| 20110057380 | IMAGE FORMING APPARATUS - Disclosed is an image forming apparatus that includes an image forming unit that forms an image and a conveyance unit that conveys a medium to be recorded opposing the image forming unit. The conveyance unit includes a platen member that guides the medium to be recorded and has plural suction holes formed therein, plural air chambers that the plural suction holes formed in the platen member face, and plural suction units that suction air inside the plural air chambers through the suction holes. At least two or more of the plural air chambers are arranged in a direction crossing a conveyance direction of the medium to be recorded. One of the plural air chambers is connected to one of the plural suction units, and one or two or more of the plural air chambers is connected to at least one of the plural suction units. | 03-10-2011 |

| 20110064497 | Image forming apparatus - An image forming apparatus including an image forming unit to form an image on a sheet, disposed in an upper portion of the image forming apparatus; at least upper and lower sheet roll supporters provided one above the other below the image forming unit to support a sheet roll, the lower sheet roll supporter offset proximally toward a front surface of the image forming apparatus from the upper sheet roll supporter; and multiple openings provided in the front surface of the image forming apparatus for the at least upper and lower sheet roll supporters through which the sheet roll is set to the at least upper and lower sheet roll supporters, an upper edge of the opening for the upper sheet roll supporter having a sloped portion tilting downward from the front surface to the back of the image forming apparatus. | 03-17-2011 |
| 20110211210 | Image forming apparatus - An image forming apparatus including an image reading unit disposed in an upper portion of the image forming apparatus, an image forming unit disposed below the image reading unit to form an image on a sheet fed from a sheet roll, a pair of flange members attached to both lateral ends of the sheet roll in a width direction of the sheet roll, a sheet roll supporter disposed below the image reading unit in a rear portion of the image forming apparatus to support the sheet roll, an opening through which the sheet roll is set to the sheet roll supporter, and a guide assembly provided at upper and lower parts of the opening to position at least one of the pair of flange members attached to the sheet roll in the width direction to guide the sheet roll to the sheet roll supporter. | 09-01-2011 |
| 20110229242 | ROLLED PAPER DRIVING APPARATUS AND IMAGE FORMING APPARATUS - A rolled paper driving apparatus includes supporting rollers that support rolled paper in such a manner that an axis line of the rolled paper extends between the supporting rollers, the rolled paper having a core pipe in a shape of a pile; a driving roller that is pressed onto an inner circumferential surface of the core pipe of the rolled paper and gives force to rotate the rolled paper; a driving force transmission part that rotates the driving roller; and a pressing force adjustment part that adjusts a state of the driving roller being pressed onto the inner circumferential surface of the core pipe of the rolled paper. The driving roller is disposed in the inside of a triangle that has vertexes corresponding to the supporting rollers and a center of the rolled paper, respectively. | 09-22-2011 |

| 20100219581 | PAPER FEED MECHANISM AND PRINTER - 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 | 09-02-2010 |
| 20100221054 | ROLL PAPER SUPPLY MECHANISM AND ROLL PAPER PRINTER - A roll paper supply mechanism reliably prevents roll paper from rising from a desired position. The roll paper supply mechanism | 09-02-2010 |
| 20110146158 | COVER UNIT AND PRINTER - One end of the cover unit of a printer is supported freely rotatably on the device case, and a rotating shaft is disposed with both ends supported freely rotatably on the distal end. A right pressure lever and an operating lever are supported on the right end of the rotating shaft, and a left pressure lever is supported on the left end. When the operating lever rotates, the right and left pressure lever rotate in the same direction through an intervening rotation transfer member extending widthwise to the device. When the operating lever rotates when the cover is closed, the left pressure lever contacts the device case before the right pressure lever . The right and left pressure lever are set so that their rotational positions are the same when the cover starts to rise due to deformation of the rotation transfer member. | 06-23-2011 |
| 20110311292 | RECORDING MEDIUM DETECTION METHOD AND LABEL PRINTER - 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 has a reflection photosensor and a transmission photosensor disposed to the transportation path at positions separated the distance between the labels. Labels on the recording medium can always be detected by either or both the reflection photosensor and the transmission photosensor. Because the reflection photosensor is downstream from the transmission photosensor, a situation in which a black mark is at the detection position of the reflection photosensor and reflection is not detected and only the liner is at the detection position of the transmission photosensor and transmission of the detection beam is detected is avoided. Detecting transmission without detecting reflection of the detection beam therefore only occurs when the recording medium is not in the transportation path. | 12-22-2011 |

| 20090114758 | Paper supply mechanism and roll paper printer - A paper supply mechanism comprising a roll paper compartment for storing roll paper, a first side wall that can move and defines one side of the roll paper compartment, a second side wall that defines the other side of the roll paper compartment, a lock mechanism that locks the first side wall, a roll paper urging member that urges the roll paper in a storage width direction of the roll paper compartment; and a holding mechanism that operates in conjunction with the lock mechanism and holds the roll paper urging member in a predetermined position. | 05-07-2009 |
| 20090129846 | Printer - 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 | 05-21-2009 |
| 20100178094 | PRINTER WITH A PEELER MECHANISM - 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 | 07-15-2010 |
