271100060 | Endless belt separator | 10 |
20080303202 | SHEET CONVEYING DEVICE AND IMAGE FORMING APPARATUS - A fluctuation detecting unit detects a fluctuation of an endless belt generated when a sheet is brought into contact with a predetermined position of the endless belt at an upstream side in a conveying direction from a nip portion based on fluctuation information acquired by a fluctuation information acquiring unit. An entry timing estimating unit estimates entry timing of the sheet into the nip portion based on a detection of the fluctuation. A correction control unit corrects a speed fluctuation of the endless belt generated when the sheet enters the nip portion by performing a feedforward control of a first driving unit based on the entry timing. | 12-11-2008 |
20090243188 | PAPER FEEDING DEVICE AND IMAGE FORMING APPARATUS - As one embodiment, a paper feeding device is provided with a pickup roller for pulling out an uppermost positioned sheet of loaded sheets, and a paper feeding roller for transporting the sheet pulled out by the pickup roller. Spanning between the pickup roller and the paper feeding roller, a roller belt is provided that is capable of moving relatively in a circumferential direction with respect to an outer circumferential surface of the paper feeding roller. The roller belt obtains rotational drive from the pickup roller. | 10-01-2009 |
20100025916 | Feed device, and image reader and image forming apparatus incorporating the same - A feed device feeds a sheet of a recording medium, and includes a body, a support shaft, and a pickup mechanism. The pickup mechanism contacts and picks up the sheet, and includes a swingable arm and a pickup unit. The swingable arm is rotatably mounted on a support shaft provided in the body of the feed device, and includes a fulcrum shaft. The pickup unit is rotatably attached to the fulcrum shaft of the swingable arm, and includes an endless elastic belt, a first pulley, a supporter, and a second pulley. | 02-04-2010 |
20110148026 | SYSTEM FOR GUIDING MEDIA IN AN IMAGING APPARATUS - A guiding system for diverting media from an input media path to an output media path in an imaging system eliminates marking and curling of media. The system employs a drive roll, an idling belt carried on one or more idler rolls, and a release roll. The idling belt presses media onto the drive roll, eliminating the relative motion between media and the drive roll and hence avoiding marking. The penetration of the release roll into the drive roll controls curling of media. | 06-23-2011 |
20110291348 | DOCUMENT FEEDER WITH PIVOTING DELIVERY TABLE, PARTICULARLY FOR DIGITAL PRINTERS - A sheet feeder assembly ( | 12-01-2011 |
20120193861 | Sheet Feeding Device and Image Forming Apparatus Incorporating Same - A sheet feeding device includes a sheet carrying unit, an attraction separation device electrostatically attracting and separating an uppermost sheet from a sheet stack and including multiple rollers, an endless dielectric belt stretched over the multiple rollers, and an elastic member provided inside a loop of the belt to cause the endless dielectric belt to contact the uppermost sheet, a sheet conveying device, and a lifting and lowering device. The lifting and lowering device lifts the sheet stack to a lift position at which the uppermost sheet contacts with the attraction separation device, and the attraction separation device stands by for a predetermined time to attract the uppermost sheet and starts to convey the uppermost sheet after the predetermined time elapses in a state in which the sheet stack remains at the lift position. | 08-02-2012 |

20110133388 | MEDIUM CONVEYANCE MECHANISM (DEVICE) - Aligning of banknotes is carried out without using an aligning device. A medium conveyance mechanism includes an upper belt ( | 06-09-2011 |
20120056366 | PRINTING APPARATUS AND PAPER HOLDING DEVICE - Embodiments described herein are to a printing apparatus includes a printing mechanism to print information on a plurality of paper sheets and further to sequentially convey the printed paper sheets along a first conveying path. The apparatus further includes a paper holding mechanism provided downstream from the printing mechanism in a paper feed direction, which includes a pair of conveying members configured to face each other via the first conveying path. The apparatus further includes a control unit configured to control the printing mechanism and the paper holding mechanism to convey sequentially the printed paper sheets through a gap between the pair of conveying members so that the printed paper sheets are sequentially accumulated in the paper holding mechanism, and further configured to collectively discharge the printed paper sheets outside of the apparatus by holding the printed paper sheets between the pair of conveying members. | 03-08-2012 |
271100080 | To rotary conveyor | 2 |
20120193862 | SHEET TRANSPORT DEVICE AND IMAGE FORMING APPARATUS - A sheet transport device and an image forming apparatus using the sheet transport device are disclosed. The sheet transport device includes a transport belt rotating around rollers that transports a sheet by attaching the sheet to the transport belt by an electrostatic force, and charging unit that is unitized by including a charging member for charging the transport belt. The charging unit includes a unit case containing springs for pushing the charging member onto the transport belt. An Ac bias voltage is applied to the transport belt via the charging member. | 08-02-2012 |
20140054843 | IMAGE FORMING APPARATUS - An image forming apparatus includes a device main body, a detachable unit that is detachable and attachable to the device main body, a sheet guide that guides a pathway of sheet, and a guide position part that regulates a position of the sheet guide. The guide position part is disposed in the device main body, the sheet guide is disposed movably with respect to the detachable unit, and when the detachable unit is mounted on the device main body, a position of the sheet guide is regulated by abutting the guide position part. | 02-27-2014 |
