A sheet feeder includes a first rotary member, a separation member that cooperates with the first rotary member in holding the sheet between the separation member and the first rotary member to define a separation nip, a conveyance unit disposed downstream of the separation nip in a conveyance direction of the sheet, a driving unit, and a control unit. The first rotary member feeds a sheet. The conveyance unit conveys the sheet. The driving unit drives the first rotary member. The control unit controls the driving unit to stop driving the first rotary member when a leading edge of the sheet reaches the conveyance unit, and controls the driving unit to restart driving the first rotary member when a trailing edge portion of the sheet comes out of the separation nip.

A media processing device includes: a hopper supporting media units (e.g. cards), and a biasing assembly biasing the cards toward a hopper outlet; an input roller for accepting a single card at a hopper slot inlet; a pick roller at the outlet for dispensing a card from the hopper to a media processing path; a motor having an output shaft; a primary drivetrain segment connecting the output shaft with the pick roller; an auxiliary output selector connected to the primary drivetrain segment and switchable between first and second output configurations; first and second auxiliary drivetrain segments connecting the output selector, respectively, with the input roller and a release member for disengaging the biasing assembly; and a selector input movable to switch the output selector between the first output configuration, coupling the primary and first auxiliary drivetrain segments, and the second output configuration, coupling the primary and second auxiliary drivetrain segments.

A medium transport device includes a drive source, a transport path through which a medium is transported in a transport direction between a first path surface and a second path surface located away from the first path surface, a plurality of projecting portions that projects from the first path surface and is arranged in a width direction intersecting the transport direction, and a moving portion that changes a projecting amount of the projecting portions with respect to the first path surface by power of the drive source between the first path surface and the second path surface.

An image forming apparatus includes a reconveying unit including a reconveying roller; and a second transmission mechanism. The second transmission mechanism transmits a drive force to the reconveying roller and includes an input gear; an output gear; an intermediate gear including first and second gears; and first and second swinging gears. The first toothless part of the first gear and the second toothless part of the second gear are provided at such a position that, when the intermediate gear is rotated by a drive force transmitted from the input gear through the second swinging gear while the second swinging gear meshes with the second toothed part of the second gear and the output gear meshes with the first toothed part of the first gear, the first toothless part reaches a position confronting the output gear and then the second toothless part reaches a position confronting the second swinging gear.

An apparatus for winding straps comprises a motor having a shaft extending therefrom to a distal end, the shaft being rotatable thereby along a shaft axis and having a slot extending longitudinally therealong from the distal end. The apparatus further comprises a spool guide located proximate to the distal end of the shaft adapted to retain a strap on the shaft and a strap guide extending parallel to and spaced apart from the shaft axis.

A transmission device includes a pickup roller assembly, a feeding roller assembly including a feeding shaft, a paper-out roller assembly including a paper-out shaft, a driving motor, a one-way drive gear module, a first transmission gear module, a second transmission gear module and a one-way clutch. The first transmission gear module includes a plurality of transmission gears disposed to two ends of the feeding shaft and two ends of the paper-out shaft. The second transmission gear module is engaged with one of the transmission gears mounted around one end of the feeding shaft. The one-way clutch disposed between the feeding shaft and the paper-out shaft, includes a first clutch gear, a second clutch gear, a third one-way clutch gear disposed between the first clutch gear and the second clutch gear, and a compression spring disposed to one end of the second clutch gear.

A sheet feeding device, which is included in an image forming apparatus, includes a reference face, a sheet loader, an air blowing device, an air drawing device, and a conveying body. The reference face stands upwardly at a downstream side of a sheet conveying direction. The sheet loader includes a body and a leading end disposed downstream from the body in the sheet conveying direction. The sheet loader moves upwardly to a position where the leading end rotates downwardly to the body. The air blowing device blows air toward a sheet bundle loaded on the sheet loader and lift an uppermost sheet of the sheet bundle. The air drawing device is configured to draw the uppermost sheet. The conveying body conveys the uppermost sheet in the sheet conveying direction while the uppermost sheet is in contact with the air drawing device due to attraction by air.

A reject storage box is provided with a sufficiently thick cover body above a second storage space that stores banknote bundles W that a user has forgotten to take, and a guide space is provided penetrating the cover body in an oblique direction. In the reject storage box, when a banknote bundle falls into an intake hole from above, a lower face of the banknote bundle immediately contacts a position toward the top of a main guide face, and the banknote bundle W travels downward through the guide space with the lower face of the banknote bundle W sliding against the main guide face. The reject storage box thereby enables the banknote bundle dropping downward through the guide space to be maintained in a substantially uniform orientation, and ultimately enables the banknote bundle to be stacked neatly inside the second storage space.

An image forming apparatus includes a reconveying unit including a reconveying roller; and a second transmission mechanism. The second transmission mechanism transmits a drive force to the reconveying roller and includes an input gear; an output gear; an intermediate gear including first and second gears; and first and second swinging gears. The first toothless part of the first gear and the second toothless part of the second gear are provided at such a position that, when the intermediate gear is rotated by a drive force transmitted from the input gear through the second swinging gear while the second swinging gear meshes with the second toothed part of the second gear and the output gear meshes with the first toothed part of the first gear, the first toothless part reaches a position confronting the output gear and then the second toothless part reaches a position confronting the second swinging gear.

A sheet feeder includes a first rotary member, a separation member that cooperates with the first rotary member in holding the sheet between the separation member and the first rotary member to define a separation nip, a conveyance unit disposed downstream of the separation nip in a conveyance direction of the sheet, a driving unit, and a control unit. The first rotary member feeds a sheet. The conveyance unit conveys the sheet. The driving unit drives the first rotary member. The control unit controls the driving unit to stop driving the first rotary member when a leading edge of the sheet reaches the conveyance unit, and controls the driving unit to restart driving the first rotary member when a trailing edge portion of the sheet comes out of the separation nip.
