20090051107 | ADU TRANSPORT ROLLER DRIVING DEVICE, IMAGE FORMING APPARATUS, ADU TRANSPORT ROLLER DRIVING METHOD - An ADU transport roller driving device, an image forming apparatus and an ADU transport roller driving method, in which a phenomenon of a warp does not occur on a succeeding sheet, are provided. There are included one drive motor that drives plural transport rollers to transport sheets in an ADU, a first one-way clutch that transmits only rotation force of the drive motor in a forward direction to an entrance side transport roller disposed at an ADU entrance side in a sheet transport direction among the plural transport rollers, a second one-way clutch that transmits only rotation force of the drive motor in a reverse direction of an opposite direction to the forward direction to an exit side transport roller disposed at an ADU exit side in the sheet transport direction among the plural transport rollers, and an electromagnetic clutch capable of transmitting only the rotation force of the drive motor in the forward direction to the exit side transport roller. | 02-26-2009 |
20100061784 | CONVEYING UNIT FOR IMAGE FORMING APPARATUS - An interlock switch is switched according to the movement of a relay reversal unit rather than the movement of a front cover. The relay reversal unit is connected to a driver substrate by a drawer connector. The change-over of the interlock switch according to the movement of the relay reversal unit is turned off when margin time elapses after a cover detection switch is turned off. | 03-11-2010 |
20100301550 | IMAGE FORMING APPARATUS AND CURL DETECTING METHOD - An image forming apparatus includes a first sensor lever which rotates between a standby position where the first sensor lever crosses a sheet conveyance path obliquely from a first rotation shaft to a sheet conveyance direction downstream side of the first rotation shaft and a first sensor is turned one of ON and OFF and a retract position where the first sensor lever is retracted from the sheet conveyance path and the first sensor is turned the other of ON and OFF, and a second sensor lever which rotates between a standby position where the second sensor lever crosses the sheet conveyance path obliquely from a second rotation shaft to the sheet conveyance direction downstream side of the second rotation shaft and a second sensor is turned one of ON and OFF and a retract position where the second sensor lever is retracted from the sheet conveyance path and the second sensor is turned the other of ON and OFF. | 12-02-2010 |
20110298175 | PAPER FEEDING DEVICE - According to one embodiment, a paper feeding apparatus arranged along the left-right direction on one side of an image forming apparatus and configured to feed stacked sheets one by one in order from a top sheet to the image forming apparatus from a paper feeding side adjacent to the image forming apparatus includes: a base plate; a tray on which plural sheets are stacked; a front-side guide member; a rear-side guide member; a paper-feeding-side guide member; an opened section formed by opening one side opposite to the paper-feeding-side guide member; and an auxiliary front guide member configured to regulate a position on the front end side of the sheets. The auxiliary front guide member has a sheet guiding section configured to come into contact with a corner on the front side of the sheets placed deviating from a proper placing state and guide the corner to the auxiliary guide section. | 12-08-2011 |
