Abstract: A line-pattern formation apparatus includes: a pattern former with a display defining a pattern and a referential projection indicating a reference position of the pattern; a positioning plate including a line-pattern indicator indicating a plurality of patterns in a lateral condition and a reference-positioning indicator specifying the reference position of the patterns; and a positioner including a stand on which a sheet is placed and a fixing member for fixing the sheet placed on the stand. The fixing member is provided with fitting portions for making the positioning plate detachably attached to the fixing member.

Abstract: A punch for forming a die-cut pattern in a sheet inserted into a slit includes a punch cutter and a base having a wall portion with which the sheet comes in contact, the wall portion being constituted of a rear wall portion extending from a frontal center portion to one side of the punch and an inclined wall portion extending rearward to the other side at of the punch an angle of 45 degrees with respect to a line extending from the rear wall portion. In the slit, a first positioning member having a ruler portion extending to one side and a second positioning member having a ruler portion extending to the other side are installed so that the ruler portions are each turnable around the punch cutter positioned therebetween.

Abstract: A punch assisting apparatus usable in combination with one of a plurality of punches includes an apparatus base and a handle pivotably attached to the apparatus base, the apparatus base being provided with a punch holder integrated therein which allows the plurality of punches having different sizes to be independently positioned and fixed in accordance with their respective sizes. The punch holder is configured so as to provide both a use position and a nonuse position by changing its posture; whereby, when a punch is mounted to the punch assisting apparatus to replace the one previously mounted, the punch can always be positioned at a given position regardless of the type of punch. Since the punch assisting apparatus is provided with a punch holder combined in one piece, the punch assisting apparatus and punch holder can always be handled together, which makes managing them easier.

Abstract: In a cutting device 1 for cutting a sheet material by moving a cutting tool along a rail provided at a template, the cutting tool is configured such that a cutting blade and guide portions engaged with the rail are provided on a disc face of a rotary disc, and the rotary disc is rotatably mounted to a grasping portion. When the guide portion is engaged with the rail, the rotary disc is naturally rotated while being guided by the curved rail, and the cutting blade provided at the rotary disc is naturally oriented in the same direction as the rail.

Abstract: A line-pattern formation apparatus includes: a pattern former with a display defining a pattern and a referential projection indicating a reference position of the pattern; a positioning plate including a line-pattern indicator indicating a plurality of patterns in a lateral condition and a reference-positioning indicator specifying the reference position of the patterns; and a positioner including a stand on which a sheet is placed and a fixing member for fixing the sheet placed on the stand. The fixing member is provided with fitting portions for making the positioning plate detachably attached to the fixing member.

Abstract: A punch device includes a punch 1 and a punch auxiliary tool 3. The punch 1 includes a punch station 10 formed with a guide hole 12 and a slit 11 into which a sheet is inserted, a punching blade 13 to be guided in the guide hole, an operating section 15 for operating the punching blade, and a housing 20 having an opening 25 in which the operating section is disposed. The punch auxiliary tool 3 includes arms 36 rising from both sides of the station 30, and a pressing operating member 40 pivotally supported by the arms. An inserting/detaching opening 31 for inserting and detaching the punch is provided on a side where the pressing operating section is pivotally supported. A lower surface of the pressing operating member of the punch auxiliary tool is provided with a pressing section 41 which presses the operating section of the punch inserted from the inserting/detaching opening.

Abstract: A merchandise display implement used while being hooked on a frame bar, including an opening portion capable of housing merchandise in a condition of rowing the same, a hanger portion to be hooked on the frame bar, and a supporting leg capable of being mounted on a plane surface is constructed. Even though a shelf or a board is not provided, the merchandise can be displayed in a plane-surface manner when only the frame bar is installed on a wall in a shop. Further, since the merchandise can also be mounted on a plane surface by a supporting leg, the merchandise can also be displayed on a board, a shelf, or the like. Furthermore, only by engaging a hook with a hook engaging hole, the merchandise can also be displayed in a condition in which a plurality of merchandise display implements is connected to each other.

Abstract: An end surface of a stopper is formed so as to be thick which is substantially the same surface as an outer circumferential surface of a flange portion, and the stopper is engaged with an engaging groove formed at the flange portion, whereby an engaging portion formed at a locking piece of the stopper is elastically deformed and engages with an engaging portion formed at the flange portion. When the stopper is pulled out in the direction away from the surface of the base resisting with elastic force of the engaging portion, an opening portion of a slot can be opened. The paper cutter of the invention enables to take the slider out of a plate in spite of having a simple configuration, and prevent a falling of the slider from the plate even in conveying it.

Abstract: In order to make an extension/deletion of management function possible without interruption of a system operation and make a conversion between a plurality of management protocols possible in a network communication system for use and maintenance of a communication network, a managed object obtained by abstracting a physical subject such as a communication device or a communication service to be managed transfers from a management manager or an object server storing a plurality of managed objects on the basis of an instruction from the management manager performing a management operation and the transferred managed object is executed.
