A media processing device includes: a hopper for supporting a stack of media units (e.g. cards), the hopper including (i) a gate wall configured to abut leading edges of the media units and (ii) an outlet defined at an end of the gate wall; a pick roller at the outlet for engaging an outer one of the media units in the stack and dispensing the outer media unit from the hopper to a media processing path; the gate wall including a flexible gate at the outlet, the flexible gate configured to deflect toward the media processing path responsive to the outer media unit being driven into the flexible gate by the pick roller, wherein the outer media unit deflects when passing by the flexible gate, permitting the outer media unit to be dispensed from the hopper.

A sheet feeding apparatus includes a swing shaft to swingably support a support member, an urging member to urge a rotary separation member toward a rotary feeding member, a frame member including a first support portion to fix a first end portion of the swing shaft and a second support portion to movably support a second end portion of the swing shaft, and an adjustment mechanism having an extended opening formed in the second support portion and a fixing member configured to fix the second end portion of the swing shaft to a frame member through the extended opening. The extended opening is extended in a vertical direction and the second end portion of the swing shaft can be fixed at a plurality of positions which vary in the vertical direction to the second support portion with the fixing member.

A medium conveying apparatus includes a setting member to set a torque limiter that defines a maximum torque applied to a brake roller to a first torque limiter or a second torque limiter, a unit including the first torque limiter, the second torque limiter and the brake roller, and a transmission member to transmit a drive force to the first torque limiter. The unit is swingably supported so that a predetermined force acts on the brake roller in a direction away from the feed roller when the driving force is transmitted. A force in a direction in which the brake roller presses the feed roller when the second torque limiter defines the maximum torque applied to the brake roller is greater than the force in the direction in which the brake roller presses the feed roller when the first torque limiter defines the maximum torque applied to the brake roller.

Provided is an apparatus that can reduce a braking force of a medium separating mechanism to thereby reduce occurrence of paper jams only by attaching a medium supply device to an image forming apparatus body. The medium supply device is configured to be attached to an image forming apparatus body including a medium separating mechanism, and includes a medium conveying mechanism that supplies a recording medium from stacked recording media to a predetermined position, and first mechanism that reduces a braking force generated in the medium separating mechanism.

A paper feeding device 100 includes a support hook 5 that supports a lower edge of a front side of a bundle of stacked paper sheets X, and a paper trailing edge storing part 32 provided between a lower end of the abutting surface 31 and the paper feeding table 11, and the paper feeding device retracts the lowermost layer paper sheet of the loaded paper sheets so as to store its trailing edge in the paper trailing edge storing part 32 and then advance it.

A media separation apparatus may include: a pickup roller disposed at one side of the loaded media, and configured to sequentially pick up and transfer the loaded media; a feed roller disposed separately from the pickup roller in a media feeding direction, and configured to feed the media picked up and transferred by the pickup roller toward a transfer path; and a media separator disposed at a position facing the feed roller, having a plurality of separation rollers and a separation belt wound around a part of the circumference of each of the separation rollers, and configured to separate a following medium from a leading medium through friction of the separation belt, the following medium being in close contact with the leading medium fed by the feed roller and transferred at the same time as the leading medium.

A printing apparatus includes a first transport roller pair configured to transport a medium while nipping the medium at a first nip portion, a second transport roller pair disposed downstream of the first transport roller pair and configured to transport the medium while nipping the medium at a second nip portion, and a device disposed between the first transport roller pair and the second transport roller pair in a transport path for the medium, and configured to nip the medium at a third nip portion, wherein a nip force in the third nip portion is weaker than a nip force in the first nip portion, and in a state where the medium is nipped at the first nip portion, a leading end of the medium is aligned with the second nip portion, and then the nipping at the first nip portion is released.

A sheet conveyance apparatus includes: a support member having a support surface configured to support sheets, a feed unit configured to feed the sheets stacked on the support surface in a feed direction, a guide member provided on the downstream side of the support member in the feed direction, and a separating member projecting from an inclined surface of the guide member toward the support surface. The inclined surface is curved such that a separating area where the separating member is provided comes closest to the side of the support surface. The support surface has a first support surface located on the immediate upstream side in the feed direction to correspond to the separating area, and second support surfaces arranged respectively on both sides of the first support surface in a direction orthogonal to the feed direction to be lowered than the first support surface.

An object of the invention is to provide a sheet materials separation-aiding apparatus capable of creating a gap between a specific sheet material and a sheet material coming into contact with the lower surface thereof even when the location precision of a stack of laminated sheet materials is low in the height direction of the stack of laminated sheet materials and in the direction orthogonal to the height direction.

An image forming apparatus includes a feeder unit, a separating unit, a conveying unit disposed downstream of the separating unit in a sheet feeding direction, an image forming unit disposed downstream of the conveying unit in the sheet feeding direction, a drive unit, and a control unit. The feeder unit feeds a sheet. The separating unit separates sheets fed by the feeder unit one by one. The conveying unit conveys the sheet. The image forming unit forms, while the sheet is being conveyed, an image on the sheet. The drive unit drives the conveying unit. The control unit controls the drive unit. After the conveyed sheet reaches the image forming unit, the control unit reduces a conveyance speed of the sheet conveyed by the conveying unit.
