Description

TECHNICAL FIELD

This invention is related to a paper feeder device. It is suitable for all kinds of paper rolls including cleaning, cooking or packing paper feeder device, for example toilet paper, wiping paper, kitchen wiping paper, for cooking using paper or tinfoil paper which all are coiled paper especially a giving paper device which could accomplish the taking paper action operated on one hand.

BACKGROUND ART

In our daily life, the using range of the paper roll is getting much more extensive. Taking the paper roll cleaning as an example, for taking conveniently purpose, it already exist many kinds of paper roll containers for cleaning paper roll usage, which could place the cleaning paper roll into the paper roll container for taking. When taking the paper, first we have to pull out an appropriate length of the paper tape by one hand, and then pull apart by the other hand. Therefore, for making convenient cutting of the paper roll while taking the paper, there are some cleaning paper rolls having a easy-tear tearing line in every length of distance in the paper tape. Besides, some paper roll containers have a cutting contiguous serration design on the paper export. It is also for the cutting paper purpose.

But in the illustrated method, it usually use both hands to get out the paper tape and tear form the paper roll container. When users can't operate on both hands but only accomplish the taking paper action on only one hand, according to the formerly experiences, it would obviously have some incommodities and persecutes in the process of taking paper. Common situations including the paper tape were pulled out over length and the cutting side presented irregular. From this we could know that there are some problems need to be improved of the usage of the paper roll container, especially the operating convenience while taking paper.

SUMMARY OF THE INVENTION

One of the aspects of the invention is to provide a single-hand-operate paper roll giving device. To reach the illustrated investment goal, this invention put forward the following technical methods:

We set up a pushing movable shelf and place the paper roll in the shelf. This paper of the paper roll could be pulled out and formed paper tape. The paper export of the shelf set a cutting paper device. This paper tape goes through the cutting paper device and extends outward. We can pulled out the extended paper head to the needed length, and then push the shelf of the same hand which could cutting the paper tape of the cutting device placed in the shelf, and then achieve the of giving paper on single hand function.

This whole shelf of this invention is composed of suitable pieces. There are some suitable connection devices so that every shelf could exercise to each other or open the shelf and put the paper roll in it. The cutting paper device could be accomplished by pushing the shelf by one hand. This hand-driving and hand-contact push is tantamount to the extension and expansion of the button of the cutlery, and it could transform to the shelf or a part of the shelf. Pushing the shelf which having a button function by hand could drive the cutting device and cut the paper tape. It is easy to push by the hand or suitable position owing to the big area and crippling of the transformed button. It is convenient and exerted stronger power to drive the cutting paper device. Part of the shelf could also fix this invention to the wall or fixity or form support shelf so that it could place on the table.

This cutting paper device of this invention has a open-close cutlery. When it opens, the paper could pass in the middle of the cutlery. And when it closes, it could cut off the paper. Because there is a length from pulling out the paper tape to the cutting device, when the cutlery cut the paper, the paper between the cutlery and the paper roll must fallen down if we let it suspend on the air, so that it would drop into the shelf, but away from the paper export. When we need to pull out the paper again, we need to go deep into the shelf and to scoop up from the inside of the shelf which formed difficulty. Therefore, this invention also set an appropriate supported and clipped for paper roll tissues.

In addition, having the aid of this supported and clipped device, it could reduce the bending deflection when it was soft and lacking strength. And it also could avoid the arcuation while the paper is pushed or shifted. Moreover, when the paper is cut, the left residual paper between the cutlery and the paper roll is inconvenient pulled out by hands, so that this invention is also set a paper tape delivery supported device, which could deliver the front of the paper to the cutting paper device and the paper export of the shelf. It is convenient to pull of the emissive length thus it could pull out the paper of the paper roll. It could clip the paper while cutting, or clip the paper between the cutlery and the paper roll after the cut but before the paper delivering of the paper tape pushing and supported device so that it could avoid the movement of the paper and which is convenient to the pushing and delivering action of the paper tape pushing and delivering device. Besides, for convenient deliver the soft paper tape, this invention also set a paper tape strong device which set on the passing through path of the paper tape which including bossy and hollow appearance and located on at least one side of the paper tape. The paper tape would touch the appearance and make the cross section of the paper tape became anfractuous and intricate which lead to a convenient delivery by the strong and non-atilt of the delivery direction of the paper tape.

Because it would be a series action of pulling out and cutting by using the pulling-out hand to pushing forward and cut the paper and it is easy to accomplish and quite accommodating by only single hand.

DESCRIPTION OF THE EMBODIMENT

This invention provided a giving paper device for paper roll paper. It is contained a movable shelf pushed by hands or other members. The shelf has a place space for put or place the paper roll, and there is a cutting device of the paper export of the shelf. Through pushing the shelf, the paper roll paper could have a movement in the place space which including trundle, rotation, movement or combined movement. When the paper roll is pulling out, it would form a pulled-out paper tape in the shelf, which is extensive by through this cutting device. By the driving ability of pushing the shelf, it would cut the paper tape into part via appropriate device which driving the action of the cutting device placed on the shelf. Owing to the pushing and the extending, transition when return to the position, the front of the paper would automatically extend towards outside to make a convenient giving paper at the next time when the shelf is returned to its position.

The illustrated shelf could compose using two or many relatively-exercised device. The paper roll could place into the formed chamber composed of the illustrated devices. Through the relative exercise of every shelf, it could make the paper roll or rotate and pull out and then form a paper tape. When every shelf were relatively exercised, it would interlock or reach the limit of the cutlery placed on the shelf of the cutting device and the suitable device to the cutlery (also could be cutlery) and then cut down the pulled-out paper tape.

For making a smooth delivering of the paper tape, which is pulled out of the paper roll, there is a paper tape pushing and supported device on the illustrated shelf which could compose to the cutting device. When the paper tape is pulled out or pushed to the established length, through the supported and fixed of the paper tape pushing and supported device and cutting down the paper roll of the cutting device, it could avoid the return-to-the-position and fallen of paper tape. In addition, the front of the paper could be curved or wrinkled at the same time when it was gripped which could raise the rigidity of the front of the paper and the friction while contacting other devices, thus assured a smooth delivery of the front of the paper when the shelf returned to its position, the grasped paper tape would relax gradually and delivery the front of the paper to the paper expert.

Moreover, for convenient delivering the soft paper, this invention is including a paper tape strong device, which is set on the pass of the paper tape. The paper tape strong device is including a crippling or swaying shape in at least one side, the paper tape touch the shape and make the cross of the paper tape to be winding or intricate which could make the delivering direction strong and not easy-tilted. The described crippling or swaying shape could be series winding or formed by discontinuity crippling things. The appropriate discontinuity could make the cross of the paper tape series winding or intricate by pushing the side of the paper tape.

For a better controlled of the intricate of the paper tape, we could set the described rippling or swaying shape on the two sides of the paper tape. Moreover, we could make the rippling or swaying shape which set on the two sides of the paper tape grip to each other and also the make the cross of the paper tape near to the gripped place winding or intricate so that led to a convenient delivery. According to the illustration, this invention also set a single-operated paper giving device. The following is a further discussion of this invention combined with embodiment and photograph.

Embodiment 1

As illustrated in FIG. 1 to FIG. 4, this embodiment is including a shelf which could contain a paper roll, a cutting device and a paper tape pushing and supported device. The illustrated shelf is relatively composed from a first shelf 11, a second shelf 12 and a driving shelf 13 which could cover the two shelves described above. When the first shelf 11 and the second shelf 12 are composed together, there is a placed space for paper roll movement.

As illustrated in FIG. 1:

The illustrated first shelf 11 is composed of two bilateral side plates 111 to a sunken structure and among the sole of the beneath these two side plates 111 has set a spring slice 112. Each of these two side plates has a crippling out axis 113 which positioned at the same axis of the spring slice 112. This spring slice 112 has a fixed side 1121 and a movable side 1122. This fixed side 1121 is fixed on the underneath of the first shelf 11, and the spring slice 112 is winding when it is not under a pressure state.

The illustrated second shelf 12 is also composed of two bilateral side plates 122 to a sunken structure corresponding to first shelf 11. Each of the illustrated two side plates 122 has a axis aperture 121 which match the axis 113 of the first shelf 11. The axis 113 could place on the axis aperture 121 and rotate in it which articulate and link the second shelf 12 and the first shelf 11 which compose a place closed interval for the paper roll and other members.

The illustrated driving shelf 13 is including an easy-human-push driving plane 131. Extending downward form the driving plane 131, there are two extending arm 132. There is a paper export 133 on the driving plane 131. The illustrated driving shelf 13 is tantamount to a large push-button. The driving plane 131 is cover to the second shelf 12 and the first shelf 11. Each of the front head of the two extending arm 132 has set a aperture 1321 which is over semi-circle. This aperture 1321 is matching to the axis 113 of the first shelf 11 which could use to set on the axis 113. The paper export 133 of the described driving plane 131 is cross connection to form a “cross” shape by the first export 1331 and the second export 1332. The first export 1331 is longer and narrower than second export 1332, and the width of the first export 1331 is a little wider than the width of the paper roll which is easy extend for the front of the front of the paper and go far as to the second export 1332 is convenient for putting fingers in.

As illustrated in FIG. 2 and FIG. 3, in this embodiment, the bottom of the first shelf 11 and the second shelf 12 are linked together and symmetrical to form an inner space. Placing the axis 113 of the under part of the first shelf 11 to the axis aperture 121 of the second shelf 12 could make a rotation of the first shelf 11 and the second shelf 12 to each other. The upper extreme of the illustrated driving shelf 13 is cover to the upper extreme of the combination of the first shelf 11 and the second shelf 12. The aperture 1321 of the underneath of the driving shelf 13 is block to the axis 113 of the first shelf 11, herewith this to form a open- and -close action from the first shelf 11 and the second shelf 12 doing actions to each other by pushing the driving shelf 13.

The illustrated cutting device is placed on the top of the first shelf 11 and the second shelf 12 and it is including a relative set up cutlery device and accessories which is placed on the two sides of the paper tape.

The illustrated cutlery device is including a cutlery seat 21. The bottom of this cutlery seat 21 is connected to the top of the first shelf 11 and merged into an integral whole, which process with the first shelf 11 and there also is a first cutlery 211 on the top of it.

The illustrated cutlery seat 21 is installed on a little backward of the cutlery seat 21. The appearance of the first cutlery 211 is matched to the cutlery seat 21, and the edge of the cutlery is 2114. The two heads 212 of the cutlery seat 21 are extended forward, and the middle part 213 is concave backward. Because of it, the front edge of the cutlery seat 21 is assumable formed a “>” winding or curved shape. At the same time, the horizontal length of the first cutlery 211 is gradually increase from the side end 2111 to the middle part 2112, that is bulge above from the middle part, which assumable like “”.

The illustrated accessories are including a coordinating seat 22 homologous to the cutlery seat 21 which is set on the top of the second shelf 12 and connected to an integral whole. It is also processed with the second shelf 12 as an integral whole. There is a tilted part on the two processed ends. There is a second cutlery 221 of the down extreme of the coordinating seat 22 together with the first cutlery 211 to cut down the paper tape R1. There is a extending forward, tilted beneath and an arc transitional piece guiding plane 2221 which is suitable for the illustrated tilted part 222 of the second cutlery 221.

For making sure that the contact of the first cutlery 211 and the second cutlery 221 are both landed on the cutter edges of the first cutlery 211 and the second cutlery 221 but not other surfaces of the cutleries, it could make a more crippling surface than other cutleries while these two cutleries are processing. A simple and effective method is to gradually increase the horizontal length of the two sides end 2111 and the middle part 2112 of the first shelf 211. That is to make a bulge upward of the middle part, so that it needs only one horizontal beeline-shape cutter edge which could make the contacted points all fall on the cutter edge. On the other way, it could relatively process a plane shape of the first shelf 211 and also process a gradually bulge downward shape from two sides to the middle part of the second shelf 211. Or it could also process the gradually bulge from two sides to the middle of the first shelf 211 and the second shelf 221 but the first shelf 211 is bulge upward and the second shelf 221 is bulge downward. In addition, every cutlery and cutlery seat are flexible which making sure the cutter edge would contact closely to the contacted point when cutting.

The cutlery and accessories of this cutting device could also be other device, for example: the illustrated cutlery could be flat surface cutlery, and the cutter edge would be beeline or curve. The accessories could have a cutter edge or without cutter edge. The structure design could suitable to the accessories and the illustrated cutlery when the first shelf 11 and the second shelf 12 exercising to each other which form a cross-cutting or compensated-cutting method to achieve the ability of cut down the paper tape.

Owing to the pulled-out paper from the paper roll R (see FIG. 2 and FIG. 3) pass a section of distance and then enter to the cutting device, after the cutting-device cutting down the paper, and let the paper tape R1 between the cutting device and the paper roll R suspense on the air, it must fall down and fall into the shelf but away from the paper export 133 of the shelf 13. When pulling-out the paper again, we need to deeply enter the inner space of the shelf of the paper export 133 which forms difficulty. Moreover, when the paper tape R1 is cutting down, the paper which exists between the cutting device and the paper roll R is not convenient to pull by hands. Therefore, this invention has set a suitable paper supported and paper tape pushing supported device to solve this question. In this embodiment, the paper support, the supported structure and the paper pushing have many sharing components and parts to form a paper supported and pushing paper tape pushing and supported device. The illustrated paper tape pushing device mainly includes a symmetric first supporting shelf 31 and the second supporting shelf 32 which set on the first shelf 11 and the second shelf 12.

As illustrated in FIG. 2 and FIG. 3, the described first supporting shelf 31 is including body 311, two activity arms 312 and two location pieces 315. The illustrated body 311 is a rectangular member. Each of the two ends of the body 311 set an extended activity arms 312. The top of these two activity arms 312 are fixed on the inner side of the first shelf 11. The illustrated activity arms 312 are made from flexible materials which could make the activity arms 312 have flexible winding. On the two ends of the body 311 and cross the activity arms 312 with a 70 degrees angle direction, there are two concave and raised location pieces 315 which are up-right.

Correspondingly, the illustrated second supporting shelf 32 is including the body 321, two active arms 322 and two position pieces 325. The illustrated body 321 is a rectangular member. Each of the two ends of the body 311 set two extended activity arms 322. The top of these two activity arms 322 are fixed on the inner side of the first shelf 12. The illustrated activity arms 322 are made from flexible materials which could make the activity arms 322 have flexible winding. On the two ends of the body 321 and cross the activity arms 322 with a 70 degrees angle direction, there are two concave and raised location pieces 325 whose concave and raised shape is matching to ones on the first supporting shelf 31. The first supporting shelf 31 and the second supporting shelf 32 are in focus and hooked up to each other to achieve the position of these two shelves (having a supported ability of a supported structure).

For promising to transfer soft papers, this invention is including a paper tape strong device, as illustrated in FIG. 1. In the middle part on the body 311,321 of the first supporting shelf 31 and second supporting shelf 32 and at the same extended direction of the location piece 315 and location piece 325, there are two extended branching claws 316, 326 to form a protrusion disconnected to each other. As illustrated in FIG. 2 and FIG. 2a, two branching claws 316,326 form a cross state to each other nearby the back side. The broadside is cross arrangement. When the two branching claws 316,326 are crossing and gripping at paper tape R1, it is allowed a broadside winding passing through for the paper tape R1. Like this way, making the paper tape R1 passing the two branching claws 316,326 of the paper tape R1 have these broad wise or/and longitudinal crippling and sunken shapes to make the paper tape R1 contact to the illustrated branching claws 316,326 and let the cross section assume winding or twisty which could raise the rigidity of the paper tape R1 and avoid it fall down, at the same time could grip the paper tape with a suitable elasticity. Here we explain that the body 311, 321 of the first supporting shelf 31 and the second supporting shelf 32 and the two branching claws 316,326 all can't grip the paper tape tight closely, because when the top of the first shelf 11 and the second shelf 12 gather up and the body 311,321 shift downward, the top of the two branching claws 316,326 must glide downward over the paper but without pull down the paper tape R1.

The first supporting shelf 31 and the second supporting shelf 32 of the illustrated paper tape pushing supported device are block together. The branching claw 316 of the first supporting shelf 31 is interlocked with the branching claw 326 of the second supporting shelf.

The concave and the raised shape of the location piece 315 and the location piece 325 are suitable and fit to each other, and make the first supporting shelf 31 and the second supporting shelf 32 are in focus and buckled to each other. The first supporting device 31 is fixed on the inner part of the ridge of the second shelf 12 by through the activity arm 322 which could make the paper tape pushing and supported device is just under the cutting device. The paper roll R is placed on the inner space constituted from the first shelf 11 and the second shelf 12. The bottom of the paper roll is carried form the spring slice 112 and positioned under the paper tape pushing and supported device. The front of the paper R2 could get through the intricate channel 33 formed from the branching claw 316 and the branching claw 326. The front section of the intricate channel 33 is formed of the gap of the right and left two bodies 311,321, and the back section of the intricate channel 33 is formed by the interlocked two branching claws 316,326, and penetrated form the paper export 144 of the driving shelf 13 to making the next pull convenient for the users.

Normalcy, the paper roll R maintained in the middle position of the inner space of the shelf 1 when passing through restricted by the first supporting shelf 31 and the second supporting shelf 32. The concave and winding shapes are cross to each other above the inner space which suitable for the location piece 315 and the location piece 325 on the two supported shelves. The pulled-out paper tape R1 is gripped by the crossed branching claw 316 and the branching claw 326, and stretch upward when passing the intricate channel 33. The front of the paper R2 which upward extended could extend outward of the shelf for a convenient pulling-out by hands when passing through to the paper export 131 of the driving shelf 13. Because the paper tape R1 is gripped by the crossed over of branching claw 316 and branching claw 326 to make it form a curved shape (cross section or dominated plane), the upward part could keep upright but not crashed which is convenient for pulling out by hands.

When pulled out the needed length of the paper tape R1 by upward-pulling hands, we could press down the driving shelf 13 by hand. These two extending arm 132 which underneath the driving shelf 13 contact the axis 113 when passing through the aperture 1321 to make it shift downward. At this time, owing to the axis aperture 121 of the second shelf 12 is also put around the axis 113, and the bottom of the first shelf and the bottom of the second shelf 12 are fixed or placed on the fixes plane (as illustrated in the two point linked in FIG. 2 and FIG. 3). Therefore, the first shelf 11 is rotated counter-clockwise around the axis 13 and the second shelf 12 is rotated clockwise around the axis 113 (please refer to FIG. 2 and FIG. 3). The top of the first shelf 11 and the top of the second shelf would gather up. At present, the location piece 315 and the position piece 325 of the first supporting shelf 31 and the second supporting shelf 32 are suitable to each other, and each fixed on the top of the first shelf 11 and the second shelf 12 and the two supporting shelf shift downward. When pushing down by hands, we need first press the front of the paper R2 to the driving plane 131 of the driving shelf 13 (please refer to FIG. 3) and then fix the front of the paper. When the two supported shelves shift downward, the branching claw 316 and the branching claw 326 are sliding over the paper and also shift downward. At the same time that the top of the first shelf 11 and the second shelf 12 are gathering together, the first cutlery 211 and second cutlery 221 are also gathering together. The two heads 212 of the cutlery seat 21 are crippling forward, and the middle 213 is concave backward, so the front edge of the first cutlery 211 is winding or curved like “>”. The horizontal length is gradually increase from the two side end 2111 to the middle part 2112 of the first cutlery 211, which is bulge upward of the middle part roughly like “□”. Concurrently, the second cutlery 221 is also fixed on the coordinating seat 22 and there is a extend forward tilted part 222 on the two sides of the coordinating seat 22. The two sides of the second cutlery 221 sticks on the bottom of the coordinating seat 22 have a extended forward and tilted guiding plane 2221. When the first shelf 11 and the second shelf 12 gather to each other, the cutlery seat 21 and the coordinating seat 22 gather to each other at the same time. When the first cutlery 211 and the second cutlery 221 start to contact, the guiding plane 2221 first contacts to the two crippling side ends 2111 of the cutlery seat 21 which could make sure the second cutlery 221 slide into the top of the first cutlery 211 smoothly and process to cut. Since the front edge of the first cutlery 211 is winding or circuitous, the process gathering to the second cutlery 221 is point-contact from two sides to the middle part and the paper could gradually cut down along the contacted point. The cutter power at the moment of cutting is very small, and the cutting process is well-distributed and contiguous. At the same time, the first cutlery 211, the second cutlery 221, the cutlery seat 21 and the coordinating seat 22 are all flexible. The flexibility could make sure the cutter edge of these two cutleries contact closely at the contact point when cutting. When the two cutleries cross to each other, it is easy to cut off the paper tape R1.

When the hands leaving the driving shelf 13 upward, owing to the spring slice 112 on the downward of the first shelf 11, the fixed side 1121 fixed on the shelf bottom of the first shelf 11 and the movable side 1122 pressed down at the shelf bottom of the second shelf 12. The spring slice 112 is winding when without accepting pressure and it gradually smashed when press the driving shelf 13 to make the first shelf 11 and the second shelf 12 gathering to each other (please refer to FIG. 2 and FIG. 3). When the hands leaving the driving shelf 13 upward, the driving shelf 13 shifts up ward and the flexibility of the spring slice 112 let the first shelf 11 and the second shelf 12 gradually open and return to the original state. When the first shelf 11 and the second shelf 12 are opening, the left extreme of the activity arm 312 raise upward of the affection of flexibility. At the same time, the right extreme of the activity arm 322 also raise upward so that the two location pieces 315,325 and the two branching claws 316,326 shift upward. The branching claws 316,326 grip the paper tape R1 at the same time and shift upward together. At the mean time, it is increasing the distance between the first cutlery 211 and the second cutlery 221, so that the front of the paper R2 could pull out from the paper roll R by driving from the branching claw 316,326, and then pass the paper export 133 of the driving shelf 13 and extend outward from the shelf 1. The first shelf 11 and the second shelf 12 open till the top of the two shelves hamper by the driving shelf 13.

When we need to exchange the paper roll R, we could pull upward the driving shelf 13 and separate from it. (The down extreme of the aperture 1321 has an export, the material has flexibility, and the export could be prop up to make the axis 113 could fall off from the export 1321) And then separate the first shelf 11 and the second shelf 12 to make the location pieces 315,325 separate, and the first supporting shelf 31 and the second supporting shelf 32 are separated enormously, so that we could exchange the paper roll R. When put the paper roll R well, we gather the first shelf 11 and the second shelf 12 up and cover the driving shelf 13 to make the aperture 1321 buckle the axis 113. And then enter the inner space of the shelf by hands by passing the second export 1332 on the middle of the top of the driving shelf 13 and pull out the front of the paper R2.

As illustrated in FIG. 4, in this embodiment, we could cover a flexible cover 34 outside the branching claw 316 and the branching claw 326. The flexible cover 34 is a soft material and there is a claw tooth 341 upward which could increase the friction between the two branching claws 316,326 and the paper tape R1 to suit for different quality of paper rolls to prevent the slide of the front of the paper R2. The top of the illustrated branching claws 316,326 could also achieve by another structure. It could articulate a soft claw or articulate a flexible cover 34 on the top of the branching claws 316,326. There is a claw tooth 341 on the flexible cover 34. When the paper tape is pulled out along with the claw tooth 341, the hinges rotates the claw tooth 341 drifts to separate and shifts reverse to make the claw tooth 341 gradually separates the paper piece and release the paper to make a convenient pulling out of paper. When the paper tape R1 shifts reverse to the claw tooth 341, the rotation of the hinges would make the claw tooth get near to the paper piece so that it could grasp the paper tightly.

Embodiment 2

As illustrated in FIG. 5˜FIG. 7, this embodiment is also including a shelf which could space a paper roll, cutting device and a paper tape pushing supported device.

The illustrated shelf is including the first shelf 11b and the second shelf 12b. Composition of these two shelves could compose a place space for paper roll R.

The illustrated first shelf 11b could place on the fixed place. It is including a standard underside 1113b and obliquity 1114b. There are two extending arms 113b on the two ends of the illustrated standard underside 1113b extended upward, and there is an aperture 1131b on the two extending arms 113b. There is a axis 112b on the two extremes of the standard underside 1113b which extend outward each other, and the middle of the back extreme set a supported plate 114b which could block the second shelf 12b, and there is a spring blocker 115b set on the middle position of the standard underside 1113b.

The illustrated second shelf 12b is including a body 121b. The illustrated body 121b is a inverted shelf-shape device which could buckle on the first shelf 11b. The two sides of the inner space of the body 121b set a rectangular form driving cam 1223b and the front edge is obliquity 1211b. The obliquity 1211b has set a export 1224b which could allow the front of the paper R2 extends outward and there is a protruding 1222b extended outward on the down extreme. There are two side walls 1121b on the extended downward of illustrated body 121b. The down extreme of the side wall 1121b has set an axis aperture 1122b which could hinge to the axis 112b of the first shelf 11b and let the second shelf 12b could rotate and make open-close action on the first shelf 11b.

The cutting device of this embodiment is on the shelf which including a relative set cutting device and accessories which position on the two sides of the paper tape.

The illustrated cutting device is including a cutlery seat 21b. The illustrated cutlery seat 21b is on the top plane of the obliquity 1114b of the first shelf 11b which could process together with the first shelf 11b (that means that the top of the obliquity of the first shelf 11b is the cutlery's fixed seat.) The back extreme of the first cutlery 211b is fixed on the cutlery seat 21b and the two side extremes 2111b is crippling forward and the middle part 2112b is concave backward so that the front edge 2113b of the cutlery 211b is winding or curved shape.

The illustrated accessories are including a suitable seat 22b. The suitable seat 22b is an extended outward oblique board of the top of the body 121b of the second shelf. The second cutlery 221b is fixed on the bottom of the suitable seat 22b and stick with it. The illustrated second cutlery 221b is flat shape. When the first shelf and the second shelf 12b match to each other, the cutlery seat 21b and the suitable seat 22b would gather up and the cutter edge of the first cutlery 211b is gathering up with the cutter edge of the second cutlery 221b. The two cutter edges of the two cutleries are contacted to each other from two sides to the middle and the paper would be gradually cut down at the contacted point. At the same time, for making sure that the contacted points are all fall on the cutter edges of these two cutleries but not other surfaces of the cutleries when the first cutlery 211b contact to the second cutlery 221b, just like embodiment 1, we process the cutter edge much more winding than other surfaces when cutting. In other words, the horizontal length is gradually increase from the two sides ends 2111b to the middle part 2112b of the first cutlery 211b that is assumed raise upward in the middle part. The cutlery seat 21b supported the first cutlery 211b is also assumed raise upward in the middle part. For making sure that the second cutlery 221b could smoothly slide upward to the first cutlery 211b for convenient cutting at the beginning contact of the two cutleries, there is a tilted downward and arc transitional guiding piece 2115b on the two front extremes of the first cutlery. When the two cutleries gathering up, the up surface of the guiding piece 2115b would first contact to the two sides of the down surface of the second cutlery 221b to form a cross-cut method so that it could cut down the paper tape R1 placed between the two cutleries.

The cutlery and accessories of this cutting device of this embodiment could also be other device. For example: The illustrated cutlery could be flat cutlery, the cutter edge could be beeline or arc line, and the accessories could include cutter edge or not a cutter-edge device. The device design of the illustrated cutlery could fit to the accessories while the first shelf 11b is relative exercising to the second shelf 12b to form a cross cut or prop-point cut method which could also achieve the function of cut down the paper tape.

The paper tape pushing supported device of this embodiment is including a deliver frame 31b with a curve base plate 324b. The illustrated curve base plate 324b of the deliver frame 31b set a tapering and bulge deliver frame 31b. The top surface of the deliver frame 31b is obliquity or arc. When the paper roll R put on the contrary ratch 311b shift to the left or rotate on clockwise direction, it could along with the up surface 3111b of the contrary ratch 311b and slide over and the reverse exercise could be stop by the tooth point 3112b. Each of the two ends of the deliver frame 31b extend a supported branch 32b. There are an extended outward rotation shaft 321b, arc driven cam 322b and a protruding cylinder 323b on the top of the two supported branch 32b. The extended direction of the illustrated circle rotation shaft 321b and the driven cam 322b are the same. The illustrated protruding cylinder 323b is located between the rotation shaft 321b and the driven cam 322b and also located on the top of the rotation shaft 321b and the driven cam 322b. The illustrated rotation shaft 321b could place inside the aperture 1131b on the two extending arms 113b of the first shelf 11b which could make the supported branch 32b rotate around the rotation shaft 321b and swing right and left. The driven cam 322b could match t the driving cam 1223b of the second shelf 12b. There is a buckle 325b of the bottom of the curve base plate 324b of the illustrated deliver frame 31b which is suitable to the spring blocker 115b of the standard underside 1113b.

Press down the driven cam 322b, owing to the bulge rotation shaft 321b of the supported branch 32b is covered on the aperture 1131b of the first shelf 11b and could rotate; the deliver frame 31b is swing to the right to pull the paper tape R1 out from the paper roll R. When the deliver frame 31b is getting closest to the right extreme, the bulge buckle 325b of the down surface is passing the spring blocker 115b of the first shelf 11b and be blocked on the right obliquity to make the deliver frame 31b position on the right extreme temporally. On the appropriate time on the process of pressing down the second shelf 12b, the cutting device would gather up and cut down the paper. This embodiment could also go a step further to include the branching claw 23b and the branching claw 24b. The illustrated branching claw 23b is an oblique set up on at least a flexible device (could be a spring) of the obliquity 1114b of the first shelf. The bottom of the branching claw 23b is fixed on the obliquity 1114b. The illustrated branching claw 24b is a flexible device (could be a spring) set on the top of the inner space of the second shelf 12b which is corresponding to the branching claw 23b whose bottom is fixed on the top of the inner space of the second shelf 12b and the other extreme is freely spread whose top is near to the second cutlery 221b. As illustrated in FIG. 7a and FIG. 7b, for making sure the soft paper roll R isn't circuitous when it slide over the branching claw 23b and the branching claw 24b with a fast speed, the front cross-section of the illustrated two flexible branching claw 23b, 24b are curved (the branching claw 23b, 24b could have two process situation, it could be cross set up or it also could be relative set up; as in FIG. 5, there are three branching claws 23b, but there are only two branching claws 24b. Two branches of branching claws are cross set up. When the first shelf 11b and the second shelf 12b gather up, the branching claw 23b is position on the interval of the branching claw 24b, and the branching claw 24b is also position on the interval of the branching claw 23b, two of them are cross but pass to each other. And the branching claws 23b, 24b on the FIG. 6 and FIG. 7 is relative set up. The numbers of the two branching claws are same. When the first shelf 11b and the second shelf 12b are gathering up, every branching claw 23b and the branching claw 24b are in focus and conflict and the flexibility of every branching claw could let the two branches of the branching claws keep gather up with the paper tape R1 after contacted. Such set up could just simply grip the paper tape R1 tightly between the two branches of the branching claws 23b and the branching claws 24b while gather up.)

Now we illustrate the set up situation of the branching claws in FIG. 5: The cross set up of the branching claw 23b and branching claw 24b in FIG. 5 could support and grip the paper tape R1, it could also be one part of the paper tape strong device. Two branching claws 23b, 24b would cross and pass to each other when gather up, the (paper transferring) broad wise section form a crippling and concave cross shape repeatedly. The gripped paper tape R1 would be repeatedly curved. At the same time, the close range paper tape R1 near the gathering position is also related to be curved (cross-section) to make the paper stronger and not easy to be curved. When the two branching claws 23b, 24b opened, the curved shape of the paper tape R1 would not resume spreading out flat immediately, and it could deliver the paper tape R1 smoothly. In addition, the branching claw of the paper tape strong device could process the situation illustrated in FIG. 7a and FIG. 7b. The contacted point of the two branching claws assume repeatedly curved. The branching claws 23b, 24b in FIG. 7b are still fixed on the same position of the first shelf 11b and the second shelf 12b.

The paper tape R1 gripped between the branching claw 23b, 24b in the FIG. 7b is gripping to repeatedly curved (please refer to the paper tape R1 cross-section in the FIG. 7a). According to the same situation illustrated before, the paper tape R1 could deliver smoothly. Normalcy, the paper roll R is placed on the curve base plate 324b of the deliver frame 31b of the paper tape pushing supported device 3b to keep it on the former position of the inner space of the shelf 1b. When using, we pull out outward the front of the paper 2 to needed length, and then return the pulling-out hand back and press down the second shelf 12b or the extended protruding 1222b of the front extreme. At this time the branching claw 23b and the branching claw 24b of the pushing supported device 3b would first get close to each other and then gather up to fix the paper tape R1 and the rectangular driving cam 1223b of the inner side of the second shelf 12b contacts the arc driven cam 322b of the deliver frame 31b to press down the driven cam 322b. Owing to the raised rotation shaft 321b of the deliver frame 31b rotated in the covered axis aperture 1122b of the side wall 1121b of the first shelf 11b which could force the deliver frame 31b swing against the paper roll direction along with the paper roll R to pull out the paper tape R1. When the deliver frame 31b reaches to the very right position, the raised buckle 325b of the down surface of the shelf would be temporally block on the right obliquity when through the spring blocker 115b set on the shelf to make the deliver frame 31b temporally position on the right extreme.

At the appropriate time of process of pressing down the shelf 12b, the first cutlery 211b and the second cutlery 221b of the cutting device are gradually getting close and contact. When the first cutlery 211b and the second cutlery 221b start to contact, the guiding piece 2115b first contacts to the two raised sides ends 2111b of the cutlery seat 21b to ensure the second cutlery 221b slide smoothly into the top of the first cutlery 211b and process to cut. Owing to the front edge of the first cutlery 221b assumes winding or curved, the process gathering up to the second cutlery 221b contacts from two sides to middle, and the paper would gradually cut sown along the contacted point. The cutting process is well-distributed and continuous.

When the hand which holds the front of paper R2 leaves the second shelf 12b or the protruding 1222b, the spring blocker 115b fixed on the first shelf 11b would spring the deliver frame 31b (the spring blocker 115b is fixed on the standard underside 1113b of the first shelf 11b. When the second shelf 12b pressed down, it would bend the spring blocker 115b, and when the second shelf 12b released, the deliver frame 31b would be spring.) The cutting device 2b and the branching claw 23b, 24b all open and the shifting upward driving cam 1223b contacts to the protruding cylinder 323b of the deliver frame 31b to give full strength for deliver frame 31b to swing left and right. The buckle 325b presses the right obliquity of the spring blocker 115b and press the spring blocker 115b down which could separate form position on the right extreme temporally and swing to the left extreme. The paper roll R on the deliver frame 31b and the pulling-out paper tape R1 are also shifted to the left. Owing to the tapering and bulge contrary ratch 311b set on the deliver frame 31b, the paper tape R1 would slide to the paper export 1224b of the second shelf 12b along with the up surface 231b of the branching claw 23b. Finally the front of the paper R2 reveal an appropriate length outside the second shelf 12b for making the next pull convenient for users.

Embodiment 3

As illustrated in FIG. 8˜FIG. 11 and FIG. 15, this embodiment is also including a shelf which could place the paper roll, the cutting device and the paper tape pushing supported device.

The illustrated shelf is including first shelf 12c and the second shelf 10c. Composition of these two could construct a paper roll place space.

As illustrated in FIG. 8, the illustrated first shelf 12c is including a supported shelf 124c which is a “” shape device, and the back extreme could fix on the wall and there are two bilateral upward side plate 123c on the side extreme. The down extreme of the side plate 123c set a rotation shaft aperture 121c. There is a long-dimension driving groove 122c on the top extreme. The inner-concave curve plate 132c passing through the two side plates 123c and the two side plates 123c are linked to one. There is at least one triangle guiding piece 131c in front of the curve plate 132c. There is a guiding obliquity 1311c on the guiding piece 131c which could let the front of the paper R2 slide over. The illustrated second shelf 10c is placed on the first shelf 12c which including a curve base plate 105c which could sustain the paper roll R and two symmetrical curve shroud 101c which link to the curve base plate 105c. The front of the curve shroud 101c link to it by the horizontal skirt 102c. The top processes to a plane with two high extreme and low middle part and there is a concave long groove 104c in the middle. There is a rotation shaft 111c on the down extreme of the illustrated curve shroud 101c which could cover to the rotation shaft aperture 121c of the first shelf 12c and hinge to rotate. There are an axis aperture 112c and a rotation shaft 114c on the top of the curve shroud 101c.

As illustrated in FIG. 9, there is a hinged third shelf 11c on the illustrated second shelf 10c. The third shelf 11c is an inverted shell-shape member. There is an extensive arm 118c extended downward of the two sides of the front edge. The bottoms of the two extensive arms 118c are both set an axis aperture 119c which could suit to the axis aperture 112c of the second shelf 10c. Both of them hinge to fix to each other. The down extreme of the illustrated third shelf 11c is corresponding to the flat structure of the second shelf 10c. After assemble, there is concave long groove 104c between the two structures.

Outside the back extreme of the second shelf 10c, there is a spring 115c located between the first shelf 12c and the second shelf 10c which is easy for the automatically homing of the second shelf 10c after rotated.

The illustrated cutting device is in the inner space of the second shelf 10c which including relatively set cutting items and accessories. The illustrated cutting items are including a shift cutlery 22c which is installed on the active seat 21c. The active seat 21c is set on the pathway of the paper tape R1 which could have a relative motion with the paper tape R1. It includes a columnar shape part arc surface 211c and two fan side plates 212c. The down extreme of the two side plates 212c extended outward has a rotation shaft 2121c. The fan top is connected to the arc surface 211c and the shift cutlery 22c is suitable for the up surface of the arc surface 211c. Two edges of the shift cutlery 22c is crippling forward and the middle is concave backward same. The shift cutlery 22c assumes curved or winding like “>”, and the horizontal length is gradually increased and the middle part is bulge upward.

The illustrated active seat 21c is rotated by driving from the crank device. This crank device is including a driving handle 4c. One extreme of the illustrated driving handle 4c has set a driving handle aperture 41c. The rotation shaft 2121c of the fan side plate 212c of the active seat 21c could get through the axis aperture 112c of the two curve side plates 101c of the second shelf 10c to suit to the corresponding driving handle aperture 41c tightly and then fixed to the driving handle 4c.

The other extreme of the driving handle 4c has set a driving pole 42c which could place in the driving groove 122c corresponding with the first shelf 12c. The driving pole 42c would driving the driving handle 4c slide in the rectangular driving groove 122c and then drive the active seat 21c rotate. Therefore the shift cutlery 22c would also drive to rotate by the driving handle 4c and slide along the rectangular driving groove 122c of the first shelf 12c. When push the horizontal skirt 102c which between the two curve side plates 101c of the second shelf 10c by hands or any component which could rotate around the introrse of the rotation shaft 111c (for example: the top cover), the paper roll would rotate clockwise around the rotation shaft 111c. When the driving pole 42c of the driving handle 4c slide in the driving groove 122c, it would twist the rotation shaft 2121c to make the shift cutlery 22c rotate counter-clockwise.

The illustrated accessories is the fixed cutlery 213c which corresponding to the shift cutlery 22c set between the two curve side plates 101c of the second shelf 10c, in front of the cutting device. The edge 2131c of the fixed cutlery 213c is located at the passage when the shift cutlery 22c rotates. When the shift cutlery 22c and the fixed cutlery 213c gathering to each other, it could make the paper tape R1 placed at it be gradually cut down along the contacted point to make the process well-distributed and continuous.

The cutlery and the accessories of the cutting device in this embodiment could be other structure. For example: The cutter edge of the illustrated shift cutlery could be beeline or arc. The accessories could be a fixed cutlery with a cutter edge or also could be other non-cutter-edge members. The structure design could corresponding suitable to the illustrated shift cutlery and the accessories when there is a relative motion between the first shelf 12c and the second shelf 10c to form a cross-cutting or prop-top cutting method which could also achieve the function to cut down the paper tape.

The illustrated paper tape pushing supported device is including a paper roll central column 33c. The illustrated paper roll central column 33c could get through the central aperture of the paper roll R. Place it to the inner space between the two curve side plates 101c which could let the paper roll. Or there is a roller 331c on the two extremes of the paper roll central column 33c which could place in the long groove 104c and slide along with the groove.

There is a regular cavity volume in the inner space of this embodiment which could allow the paper roll to do some appropriate rolling. Moreover, for making the exported paper tape R1 wouldn't lean to the right or the left side, there is an amendment piece 24c in the interior of the two curve side plates 101c. There is an appropriate arc between the amendment piece 24c and the contacted surface. If the passing paper tape leans to right or left, the edge of the paper could slide to the middle when touch the amendment piece 24c.

There is a soft and flexible paper tape guiding device 32c in front of the illustrated paper roll central column 33c, the top of the paper tape guiding device 32c is a semicircle arc which put under the pulled paper tape R1 and make it curved to enter the cutting position. It could process with the second shelf 10c or also could be an alone components and parts. The down extreme is stick to the curve base plate 105c and fix on the second shelf 10c.

In this embodiment we could make the paper tape guiding device 32c become one part of the paper tape strong device. The way of making it is to process broad wise many winding and concave curved shape on the top of the illustrated paper tape guiding device 32c. (it could process assumed the curved shape of upper extreme 312c as illustrate in FIG. 15a and FIG. 15b) It could make the paper tape R1 covered on the top of the paper tape guiding device 32c following it to form curved. At the same time, the part between the paper tape guiding device 32c and the paper roll is also related to form curved so that it could increase the rigidity of the paper tape R1 which could make it strong but not easy-winding in the delivering direction so that it could avoid it fall down on the delivering process.

As illustrated in FIG. 11, in this embodiment, there is a guiding extensive device 321c which could cross and suit for the active seat 21c near the second shelf 10c. The illustrated active seat 21c set a paper tape intricate device 322c which is cross away to the illustrated guiding extensive device 321c. And when the illustrated active seat 21c shift to the guiding extensive device 321c, it could make the paper tape R1 intricate between the guiding extensive device 321c and the paper tape intricate device 322c. The fan two side plates 212c linked to the active seat 21c of the guiding extensive device 321c in FIG. 11 assume column shape (in the cross-sectional view in this fig is circle). In reality apply, the guiding extensive device 321c shape and the paper tape intricate device 322c shape could both be plate or column or other appropriate appearance and both could produce with soft and easy-curved material and set a roller or a pillar on the surface or the contacted point at the place which contact to the paper tape which could be good for the rotation of the active seat 21c and also avoid the weak paper tape R1 to suffer a over-huge pull strength.

The paper tape R1 is pass the top arc surface of the paper tape guiding device 32c and then bend through the paper tape intricate device 322c and the guiding extensive device 321c and then pass through the fixed cutlery 213c and the shift cutlery 22c. Like this way, it could make the paper tape R1 bend repeatedly after pull to increase the short-existing length of the paper tape R1 twined in the shelf so when the active seat 21c and the second shelf 10c return to the original position, the paper tape would has enough length fall down and could make the front of the paper R2 deliver smoothly.

The passage of the paper tape R1 of the illustrated second shelf 10c has set active seat 21c which could has a relative motion to the paper tape R1. The active seat 21c could use as in two different purpose. One is to be a cutlery seat so it could place the shift cutlery 22c. The other is to curve and bind to the paper tape R1 to place the paper tape intricate device 322c. The two use members could all place at the same active seat or could also leave each other and place on two different active seat. At the other side of the paper tape R1, relative to the active seat 21c set cutlery accessories and relative to the paper tape intricate device 322c of the active seat 21c set a guiding extensive device 321c. The active seat could be plate shape or also could be stand shape which place on the side of the paper tape R1 and could rush to the paper tape R1. When take it as a cutlery seat, the shift cutlery and cutlery accessories set on the other side of the paper tape R1 could cut down the paper tape R1. When take it to curve and bind to the paper tape R1, the paper tape intricate device 322c and the guiding extensive device 321c set on the other side of the paper tape R1 would intricate the paper tape R1 repeatedly. The shift of the active seat could be act as the rotation motion linked to the shelf and the rotation shaft illustrated in this embodiment. It could be straight rush to the paper tape, the motion is just like the extend and contract pole 212d illustrated in FIG. 12 in the embodiment 4 (there is a shifted cutlery 21d on the top of it) straight rush to the paper tape (it could also consider the shifted cutlery 21d straight rush to the paper tape R1 and gather up with the fixed cutlery 22d behind the paper tape R1 and to cut down the paper tape R1) Only the driving structure of the active seat need to change, for example it could change the modeling of the active seat to extend and contract pole 212d of the embodiment 4 and change the direction (reverse end to end for 180 degrees) to get through the shelf in a horizontal leftward direction. Go so far as to the guiding aperture 14d, axle 211d, twist spiral spring 213d, aperture 214d, blocker column 215d, pulling spiral spring 216d, fixed cutlery 22d, blocker axle bearing 217d, blocker axle 221d and other structures still set as in embodiment 4 but only need to change the direction (in company with the reverse end to end for 180 degrees of the extend and contract pole and set up) and the extend and contract pole getting leftward through the shelf. Owing to the top of the extend and contract pole is more shape-pointed and not suitable for pressing by hands, so that it could connect an easy-human-push driving plane 131 (as illustrated in FIG. 1) in the embodiment 1 on the left extreme of the pole (only the driving plane change to the vertical direction and cancel the paper export on the driving plane) so that it could press comfortably by hands. When the active seat is straight rushed to the front of the paper tape and for curving the paper tape R1 use, it need to set a paper intricate piece on one extreme of the shelf of the described transforming extend and contract pole (the extend and contract pole transform to be a active seat) and set a guiding extending piece on the other side of the paper tape. This paper curved device and the guiding extending piece are cross and shift to the guiding extending piece and then it could intricate the paper tape R1 between two of them repeatedly.

Because the paper tape R1 is soft, it is easy to collapsible and droops on the process of the pull and extended, there is a paper tape supported device 31c between the paper tape guiding device 32c and the paper roll R. The paper tape supported device 31c is also a soft and flexible arc spring and its structure is similar to the paper tape guiding device 32c and the upper extreme 312c is a semi-circle arc (it could also displace the thin roller set on the top of the paper tape supported device 31c with this arc). The middle is a concave arc plane. The shape of the down extreme 311c could stick on the arc of the curve base plate 105c of the second shelf 10c and fix on the paper tape guiding device 32c or the curve base plate 105c. The top could contact the point to the paper tape R1 and also support the paper tape R1 which could let the paper slide over it smoothly to avoid it fall down. In this embodiment, it could also make the paper tape supported device 31c to be one part of the paper strong device. The way of making is illustrated in FIG. 15a and FIG. 15b; it designs many horizontal concave-convex curve shapes on the top of the illustrated paper tape supported device 31c (the upper extreme 312c as illustrated in FIGS. 15a and 15b) to make the paper tape R1 placed on the paper tape supported device 31c is also curved shape. At the same time, on the front and back area of the paper tape supported device 31c that is the part between the paper tape guiding device 32c and the paper roll is formed regular curved shape. So that it could increase the rigidity of the paper tape which could make it strong and not-easy curved on the deliver direction and avoid it fall down on the deliver process.

The shelf of the embodiment 3 must has enough capacity space to let the new-opened paper roll R do some rolling forward and backward this is the capacity distance bigger than the diameter of the new-opened paper roll to let the paper roll placed inside could roll to the forward or backward to gather up by the appropriate structure to fix the pulled-out paper tape R1 pulled out from the paper roll R and the paper roll R of the bias box-shape shelf could roll and produce drag and then pull more paper out from the paper roll R.

On the other hand, when the paper tape R1 is gripped to fix, it would cut down the paper by the cutlery device. After cutting sown the paper, the cutlery device would open and the paper which is gripped to fix is also release.

Owing to the cutter point of the shift cutlery 22c is bias to the rotated axle centre line, and the cutter edge of the fixed cutlery 213c is parallel to the rotated axle centre line of the shift cutlery 22c therefore the contact of the two cutleries when the two gather up would not be contact of all cutter edge but the point contact. The contact point shifts along the series parallel rotated axle centre line direction, these two contact point of the two cutleries would cut sown the paper. The bias of the shift cutlery 22c could be single direction lean or could be repeatedly intricate. There are several contact points process to cut at the same time (rely on the repeatedly numbers of the intricate) when the bias repeatedly intricate so that it could finish the cut in a smaller rotated degrees.

In addition, the single bias of the shift cutlery 22c to cut the paper is from one side of the paper to the other side. Sometimes it would cut to a hypotenuse but not the square scrap of paper. The repeatedly curved bias of the shift cutlery 22c could resolve this question. The “ ” shape arrangement of the cutter edge of the shift cutlery 22c would grip the two sides of paper when it starts to cut and then cut toward the middle of the paper. For one thing it could fix the for-cutting paper piece and the paper tape R1 pulled out from the paper roll. For the other thing the edge of the cut paper is more regular.

When using, we pull out the front of the paper outward to a needed length by hands and push the horizontal skirt 102c or the second shelf 10c to the right by the pull-paper hands. Owing to the driving handle 4c is rotated on the axis aperture 112c of the second shelf 10c and the driving pole 42c is on the driving groove 122c so that the second shelf 10c shifts to the right to drive the driving handle 4c rotated on the counter clockwise direction. And owing to the driving handle 4c is connected to the cutlery seat, the shift cutlery 22c is also rotated on the counter clockwise direction. On the rotation process, the front edge of the cutlery seat first contact to the paper and bend the paper along the front edge of the paper tape supported device 31c and make it curved. And then cut the paper from two side of the paper to the middle. (the contact point of the shift cutlery 22c and the fixed cutlery 213c is from two side to the middle) When the second shelf 10c rotate clockwise of the rotation shaft 111c, the bias of the long groove 104c lean from low-left-high-right to the high-left-low-right to make the paper roll central column 33c (or paper roll R) slide to the right. Owing to the pulled-out paper bend the guiding piece of the paper tape guiding device 32c and be curved in front of the guiding piece and fix and then the paper roll R shift to the right so that force the paper roll R rotate on the counter clockwise direction to let the paper pull out from the paper roll R. When the shift cutlery 22c rotated to the end point, the paper has been completely cut down. When the hand takes the paper and leaves the horizontal skirt 102c or the second shelf 10c, the pressed spring 115c bounces to push the second shelf 10c leftward to the original position to make the driving handle 4c and the cutlery seat all rotate clockwise and get back to the original position. And the long groove 104c (or the capacity of the second shelf) would return to the low-left-high-right bias to make to paper roll R rotate counter clockwise and roll to the left. And the formerly pulled-out paper and the roll-out paper are delivering to the left and carrying by the arc on the top of the paper tape supported device 31c (or set on the thin roller which replace the arc on the top of the paper tape supported device 31c) and supporting by the guiding piece of the paper tape guiding device 32c so that it could deliver smoothly. When the paper roll R roll to the left, the soft and flexible paper tape supported device 31c could be press down and into the supported groove 323c but not obstruct the shift of the paper roll R. When the shift cutlery 22c returns to the original position, the front of it would leave the paper so that the front of the delivered paper could droop and extend out of the first shelf 12c. There is a crippling guiding piece 131c of the first shelf 12c which has a guiding obliquity 1311c on it. The drooped paper contacts to the obliquity and slides to the left leading for much more extended out of the whole device. The middle of the guiding piece 131c is concave convenient enter for forefinger and hold the front of the paper R2.

There is an adapting disc 14c under the fallen-down of the front of the paper R2. The adapting disc 14c could be stationary type which could fix on the first shelf 12c or it also could be active type of this embodiment which set a raised upward and parallel axis aperture plate 15c inside the first shelf 12c. There is an axis aperture 151c of the axis aperture plate 15c. There is a raised axis 1411c on the plate-shape winding arm 141c linked to the adapting disc 14c which could install on the axis aperture 151c and let the winding arm 141c swing. There is a driving pin 1412c on the top of the winding arm 141c and the down surface of the second shelf 10c could press and push it. When push the horizontal skirt 102c or cut paper, the second shelf 10c would press down and drive the driving pin 1412c to let the winding arm 141c swing on a clockwise direction. And the adapting disc 14c would extend up and leftward to hold out the cutting-and-fallen-down paper. And the second shelf 10c would bounce upward and the adapting disc 14c would rightward and downward return to the original position to pick up the cutting paper on the adapting disc 14c.

Embodiment 4

As illustrated in FIG. 12˜FIG. 15, this embodiment is including a shelf which could place the paper roll, cutting device and a paper supported device and a paper taper pushing and delivering supported device.

The illustrated shelf is composed of the fixed shelf 12d and the active shelf 11d. The fixed shelf 12d is including a seat 121d which set on the back extreme of the fixed shelf 12d to fix it on the wall or other fixed plane. The leading end 122d of the fixed shelf 12d is arc and there is a rotation shaft 1221d on it and there is a blocker 125d on the front extreme.

The illustrated active shelf 11d is a shelf with a paper roll active groove 115d in it. It set enough capacity space for put in the paper roll which could let the new-opened paper roll R roll in the paper roll active groove 115d. That the capacity distance of it front and behind need a longer diameter than the new-opened paper roll R. There is a hinge 111d on the front active shelf 11d which could link to the side cap 101d. The side cap 101d is flat plate shape (the side cap 101d illustrated on FIG. 12 is straight opened of 90 degrees status, which is side, so it is beeline shape.) The appearance is just the same as the active shelf 11d. When the side cap 101d is closed, it could cover the all side of the active shelf 11d. There is a bulge ear 112d on the top of the illustrated active shelf 11d and there is an axis aperture 1121d on it which could cover to the rotation shaft 1221d of the fixed shelf 12d so that the active shelf 11d could suspend and hinge on the fixed shelf 12d and swing. There is a twisted spiral spring 123d covered on the rotation shaft 1221d. The one extreme 1231d could prop the underside 124d of the seat 121d and the other extreme could prop the upper surface 116d of the active shelf 11d. This elastic force of the twisted spiral spring 123d could let the active shelf 11d take the rotation shaft 1221d as a rotation center to rotate upward. And the blocker 125d extended from the fixed shelf 12d could block the upper surface 116d of the active shelf 11d to restrict the slope of the active shelf 11d. Structurally, the bottom of the active shelf 11d could change the tilted degrees. When it lean forward or backward, it could let the paper roll R placed on it roll to the front or back and the bottom of the paper roll active groove 115d of the tilted active shelf 11d could let the paper roll R process pulling on the process of rotation to pull out more paper from the paper roll R. When pull out the appropriate length by hand, the pulled-paper hand return to press the pull-out paper on the outer surface of the active shelf 11d so that to fix the pulled-out paper from paper roll R and then the press-paper hand push the active shelf 11d to make it lean to pull out more paper from the paper roll R. On the other hand, when the paper is gripping to be fixed, it could cut down the paper by through the cutting device.

The illustrated cutting device is including cutlery piece and the accessories. The illustrated cutlery piece including a stretch out and draw back shifted cutlery 21d. The accessories is including a fixed cutlery 22d, the two pieces are set relatively. The illustrated fixed cutlery 22d is fixed inside the square chamber of the back extreme of the active shelf 11d. One of the extremes is fixed on the inner wall of the square chamber. The other extreme is extended outward. The cutter edge 222d of the fixed cutlery 22d is obliquity and there is a blocker axle 221d on the top of the cutlery. The illustrated shifted cutlery 21d is set in the chamber of the back extreme of the active shelf 11d. The place is corresponding to the fixed cutlery 22d. There is an axle 211d on the cutlery. Through the axle 211d, it could connect to the extend-and-contract pole 212d and could rotate on the extend-and-contract pole 212d. The extend-and-contract pole 212d is getting through the guiding aperture 14d of the active shelf 11d and extending outside so that it could do expand and contract action. There is a twisted spiral spring 213d on the illustrated axle 211d. One edge 2131d hooks on the aperture 214d of the shifted cutlery 21d and the other edge 2132d hooks on the border of the extend-and-contract pole 212d. The elastic force of the extend-and-contract pole 212d could make the shifted cutlery 21d assume bias shape like FIG. 14. The blocker column 215d fixed on the shifted cutlery 21d prop up the border of the extend-and-contract pole 212d to restrict the slope of the shifted cutlery 21d. One extreme of the pulling spiral spring 216d connects to the extend-and-contract pole 212d, and the other extreme of it connect to the active shelf 11d. The pulling force makes the shifted cutlery 21d far away from the fixed cutlery 22d and makes the extend-and-contract pole 212d extend outward from the active shelf 11d. There is a blocker axle bearing 217d on the illustrated shifted cutlery 21d. The middle of the blocker axle bearing 217d has set a indentation 2171d which is corresponding to the blocker axle 221d. When push the active shelf 11d rotate with a counter clockwise direction along the rotation shaft 1221d, the extend-and-contract pole 212d press to the wall and draw back to the active shelf 11d. The shifted cutlery 21d set on it is also shifted leftward. The right of the cutter point 218d of the shifted cutlery is first gathering up to the cutter point 222d of the fixed cutlery (please refer to FIG. 13). And then the indentation 2171d of the blocker axle bearing 217d is cover to the blocker axle 221d. When the extend-and-contract pole 212d keeps shifting leftward, the shifted cutlery 21d is rotated clockwise and taking the blocker axle 221d as rotation central. So the gripped point would gradually shift from left to right similar to the razor, and the paper which getting through the two cutleries would be cut down.

Like the illustrated embodiment, the cutlery of the cutting device and the accessories could be other structures. For example: the illustrated arc cutter edge could be beeline or arc line, the accessories could be a fixed cutlery with a cutter edge or other structures which are not cutter edge. The structure design could corresponding to the illustrated arc cutely or accessories when there is a relative motion between the first shelf 12c and the second shelf 10c to form cross-cut or prop-top cut methods. It could also achieve the function of cutting down the paper tape R1.

The paper supported and paper tape pushing delivering device is set on the back extreme of the paper roll active groove 115d of the active shelf 11d in this embodiment. It is including the paper tape guiding device 32d whose down extreme is fixed on the bottom of the paper roll active groove 115d of the active shelf 11d. There is a semicircle arc plane on the up extreme which is extended outward from the active shelf 11d and put it under the pulled-out paper tape R1 to make it curved and enter the cutting device (the paper tape guiding device 32d could also process with the active shelf 11d, and there is a semicircle arc plane on the back extreme of the active shelf 11d.) Similar to the embodiment 3, the top of the illustrated paper tape guiding device 32d could also horizontal process many concave-convex curved shapes to make the paper tape R1 of the top of the paper tape guiding device 32d also formed curved shape to raise the rigidity of the front of the paper R2.

Between the paper roll R and paper tape guiding device 32d, there is a paper tape supported device 31d, which is soft and flexible, the underneath 311d fixed to the bottle of supported groove 113d in active shelf 11d, and the up extreme 312d is semicircle-shape, and has a arc surface (could be replace with the thin roller which setting on the top of supported plate), by touching the paper which pull out from paper roll R, can make the paper slide smoothly; the paper tape R1 which pull out from the paper roll R pass the cambered surface on the top of paper tape supported device 31d and be supported, therefore keep the paper tape R1 away from falling down and pass easier. As the FIGS. 15a and 15b, the top of paper tape supported device 31d also lateral design to numbers of wave-shape curve, make the paper tape R1 which on the top of the paper tape supported device 31d curve-shape, enhance the hardness in front of the paper R2; avoid its falling in delivery.

Paper roll R is setting in the paper roll active groove 115d in the active shelf 11d, the active shelf 11d has enough space to let the paper roll R rolling appropriately. On the other hand, to make the exported paper not slants to left or right, there are two guiding pieces 34d connect to inside of shelf by the connected pole 341d. These two guiding pieces 34d have appropriate cambered surface, if the passed paper slant to left or slant to right, the touching between the edge of paper and the guiding piece 34d can make paper slide to the center.

Focus on the descriptive shelf in previous embodiment, the shape of the shelf can be piece of shell or shell-shape, and can be brace-shape, but not limit to description and figure of embodiment. For example, the central surface and cambered surface in both of the first shelf 11 and the second shelf 12 in embodiment 1 and embodiment 2 can be hollowed out and abandon. Remained edge, crest line and crest angle are brace-shaped; and if we extend the left and the right side plate of the first shelf 12c in the embodiment 3 to the fixed wall 123c surface, the shelf will be a concave shell; and if we widen the top surface of the fixed shelf 12d in embodiment 4, and set downward side plate, the shell will be downward-covered shape.
