A medium transport device includes a feeding unit that transports a medium, a stack portion that receives the medium transported by the feeding unit between a support surface for supporting the medium in an inclined posture in which a downstream side in a transport direction is directed downward and an opposing surface opposing the support surface and stacks the medium, an alignment portion that aligns a downstream end of the medium stacked in the stack portion, a paddle that is provided between the feeding unit and the alignment portion in the transport direction and moves the medium toward the alignment portion by rotating while being in contact with the medium, and a control unit that controls an operation of the paddle, in which the control unit controls the operation of the paddle according to a condition.

An example disclosed output hopper includes a cavity to receive media units from an output of a media processing device, the cavity to cause the media units to form a stack in a first direction; a first door pivotably movable between a closed position and an open position, the first door to retain the media units in the cavity when in the closed position; a second door movable between the closed position and the open position, the second door to retain the media units in the cavity when in the closed position; wherein the first door is configured to pivot on a first axis substantially parallel to the first direction; and the second door is configured to pivot on a second axis substantially parallel to the first direction.

A sheet feeding apparatus includes a sheet supporting portion including a supporting surface, an abutment portion against which a leading edge of the sheet abuts, a feeding rotator configured to feed the sheet, and a first friction member provided on the supporting surface so as to face the feeding rotator. The first friction member includes a first friction surface having a static friction coefficient greater than that of the supporting surface, a trailing end supporting portion configured to support a trailing end portion of the sheet curved upward, and a second friction member disposed upstream of the first friction member in the sheet feeding direction on the supporting surface. The second friction member includes a second friction surface which has a static friction coefficient greater than that of the supporting surface and is configured to be in contact with the sheet supported by the supporting surface.

A media folding device includes a stacking portion on which media transported from an introduction path are placed; a folding roller pair that folds the media at a folding position after the media have been stacked in the stacking portion; and a bend forming mechanism that includes a first abutting portion configured to abut against a front end of the media, which are stacked in the stacking portion, in a transport direction, and a second abutting portion that is configured to abut against a rear end of the media, which are stacked in the stacking portion, in the transport direction, and that causes the folding position of the media to be nipped by the folding roller pair the folding roller pair by shortening the relative distance between the first abutting portion and the second abutting portion to bend the media toward the folding roller pair.

The present application provides a napkin dispenser for dispensing a number of folded napkins from a sheet material to an end user. The napkin dispenser may include a loading station for loading the sheet material, a folding station for folding a napkin from the sheet material, and a presentation station for presenting one or more of the folded napkins to the end user.

A paper sheet post-processing device includes a processing tray, an aligning member that aligns paper sheets on the processing tray, a swingable holder that supports the aligning member, a swinging mechanism that causes the holder to swing, and a control unit that controls the swinging mechanism. The swinging mechanism includes a rotation shaft inserted into a shaft insertion portion of the holder with play in a rotation direction. The control unit controls the rotation shaft to rotate and stop at a predetermined rotation angle position corresponding to a stack height of the sheets stacked on the processing tray, so that the holder is disposed at a contact position. At the contact position, the holder is allowed to swing in a retracting direction with respect to the rotation shaft within a predetermined play range. The play range is set to be larger in proportion to the stack height of the sheets.

Provided are a banknote temporary storage mechanism (400) and a banknote processing device. The banknote temporary storage mechanism (400) is configured to enable the banknote to smoothly fall without getting jammed. The banknote temporary storage mechanism (400) includes a frame (8), a first door (1) pivotally connected to the frame (8), and a banknote pushing mechanism (4). The first door (1) has an open position and a closed position. The banknote pushing mechanism (4) includes a banknote pushing member (44). The banknote pushing member (44) is movably connected to the first door (1), and protrudes from a banknote support surface of the first door (1). The banknote pushing member (44) is configured to, as the first door (1) rotates towards the open position from the closed position, to move relative to the first door (1) along a direction in which a banknote is disengaged from the first door (1), to push the banknote to be disengaged from the first door (1).

A sheet aligning device includes a support member, a regulation member, a regulation member moving mechanism, and an alignment member. The support member supports leading ends of sheets. The regulation member is connected to the support member and is provided to face an inclined tray in such a way as to define a sheet entry space in which the leading ends of the sheets enter. The regulation member moving mechanism is configured to, each time a sheet is conveyed onto the inclined tray, move the regulation member in a separating direction to widen the sheet entry space, and then in an approaching direction to narrow the sheet entry space. The alignment member aligns the sheets by abutting on rear ends of the sheets.

The present application provides a napkin dispenser for dispensing a number of folded napkins from a sheet material to an end user. The napkin dispenser may include a loading station for loading the sheet material, a folding station for folding a napkin from the sheet material, and a presentation station for presenting one or more of the folded napkins to the end user.

In a sheet feeder that feeds a sheet to an image forming apparatus, a sheet placing table has a placement surface on which a sheet is placed and is inclined downward toward a downstream side in a sheet feeding direction. A sheet detecting unit has an operation piece that presses a leading end of the sheet toward an upstream side in the sheet feeding direction with predetermined pressure. A regulating member is arranged in a vicinity of an end part of the sheet placing table on the upstream side in the sheet feeding direction. The regulating member regulates movement of the sheet to the upstream side in the sheet feeding direction and has regulating portions having different heights from the placement surface of the sheet placing table. The regulating portions are arranged so that the heights are increased toward the upstream side in the sheet feeding direction.
