  • Publication number: 20100219581
    Abstract: A printer has a paper feed mechanism that can reliably balance the paper feed force of the paper feed roller and paper pressure roller on the left and right sides of the recording paper width. Using the self-centering action of a pressure lever fulcrum 31k and adjustment of the position where an extension spring 32 applies force, the paper feed mechanism 30 of a printer 1 can press the paper pressure roller 23 that is supported by a pressure lever 31 to a paper feed roller 21 so that the paper pressure roller 23 applies equal pressure at all points along the width of the paper feed roller 21, can balance the paper feed force applied by the paper feed roller 21 and the paper pressure roller 23 to the recording paper 12a left and right widthwise to the paper, and can prevent the recording paper 12a from meandering, skewing, and jamming.

  • Publication number: 20100221054
    Abstract: A roll paper supply mechanism reliably prevents roll paper from rising from a desired position. The roll paper supply mechanism 3 of a roll paper printer 1 has an urging member 41 that urges the round end surface of the roll paper 2 to the roll paper guide 33 defining one side of the roll paper storage unit 31. The urging surface 41a of the urging member 41 is inclined to the inside in the pulling direction A of the recording paper 2a that is pulled from the roll paper 2. When seen from the side of the width of the roll paper storage unit 31, the urging surface 41a is disposed between a vertical line V through the center of gravity G of the roll paper and the recording paper pulling position D, and urges an outside edge part 2d of the roll paper 2 at a position above the recording paper pulling position D.

  • Publication number: 20100178094
    Abstract: A printer having an opening/closing cover for providing access to a roll paper compartment, a peeler mechanism for peeling printed labels from a web and for dispensing the peeled printed labels from the printer and an opening and closing mechanism 50 which locks and unlocks the cover and a peeler unit 10 of the peeler mechanism in response to the manual operation of a manual operating member such as a release button 17 with a single easy operation. When the release button 17 is depressed into a first operating position 17B, a lock lever 52 of the opening/closing mechanism 50 slides from a locked position 52A to a released position 52B to disengage the lock lever 52 thus unlocking the opening/closing cover 9. At the same time, the sliding lock lever 52 pushes engaging claws 74a, 73a that lock or unlocks the peeler unit 10.

  • Patent number: 7578332
    Abstract: A printer with a peeler mechanism 1 for peeling labels from a web, the printer having a movable web pressure roller 24 which may be moved from a web pressure position 24A in which pressure is applied to a platen roller 20 to a retracted position 24B in which pressure is not applied. The printer also has a photosensor 21 and photoreceptor having an emitter/receptor surface 21a for detecting the presence and absence of labels peeled from the web. A window 22b in the label guide surface 22a becomes covered to shield the photosensor output for defining a no-label detection stateWhether the peeler mechanism is set to operate in the label peeling mode or is set to a retracted position defining a non-peeling continuous label dispensing mode of operation can be determined based on the output of the label detection photosensor 21, and the label dispensing mode can be set to the label peeling mode or continuous label dispensing mode based on this determination.

  • Publication number: 20090129846
    Abstract: A printer having one roller of a transportation roller pair attached to cover renders the mechanism pressing the transportation roller pair together and the damping mechanism used when opening the cover using few parts, compactly, and at low cost. A damper spring 27 prevents the cover unit 3 of the printer 1 from opening suddenly and forcefully. A roller support lever 38 having the first follower roller 33b disposed to the distal end thereof is attached rotatably and movably to the cover unit 3. The roller support lever 38 is urged by the damper spring 27, and the first follower roller 33b on the distal end thereof is pressed to the first transportation roller 33a on the printer frame 11 side. The damper spring 27 functions as the damping mechanism when the cover unit 3 opens, and as the pressure mechanism of the first transportation roller pair 33 when the cover unit 3 is closed.

  • Publication number: 20090102878
    Abstract: A recording medium detection method uses transmission and reflection photosensors to correctly detect if a recording medium having labels affixed to a liner is in the transportation path. The label printer 1 has a reflection photosensor 26 and a transmission photosensor 27 disposed to the transportation path at positions separated the distance L0 between the labels 12c. Labels 12c on the recording medium 12a can always be detected by either or both the reflection photosensor 26 and the transmission photosensor 27. Because the reflection photosensor 26 is downstream from the transmission photosensor 27, a situation in which a black mark 12d is at the detection position of the reflection photosensor 26 and reflection is not detected and only the liner 12b is at the detection position of the transmission photosensor 27 and transmission of the detection beam is detected is avoided.

  • Publication number: 20090046173
    Abstract: Disclosed herein is a method of storing or transferring an image along with an image-processing parameter for processing the image. When storing or transferring a second image for storage or transfer which has a second resolution for storage or transfer differing from a reference resolution, a reference image-processing parameter set according to a reference resolution image having the reference resolution is corrected based on a difference between the reference resolution and the second resolution, so that it becomes a second parameter corresponding to the second image. The second parameter obtained by the correction is stored or transferred along with the second image.
