The first roller is rotated by a driving force supplied from a driving source, and the guide rotates about a rotation axis of the first roller while rotating relatively to the first roller.

A medium discharging device includes a first tray, a second tray receiving a medium from the first tray, a supporter which is configured to be displaced from a retreat position in the first tray and an advance position above the second tray and which supports the medium, an aligner which is provided in the supporter and that aligns a first end portion which is an upstream end portion in a discharge direction of the medium supported by the supporter, to be displaced together with the supporter, and a restrictor configured to be displaced between a restriction position where an upstream movement of the first end portion of the medium in a position of the aligner in the discharge direction and a non-restriction position where the movement is not restricted, when the supporter is in the advance position.

A banknote pay-out device includes a pay-out port where a banknote bundle is handed over to a user, a shutter that is provided so as to capable of closing or opening the pay-out port, a gripping conveyance guide and a stage that guide the banknote bundle W, and a push-out plate that is disposed facing the gripping conveyance guide and the stage, and that moves in a handover direction toward the pay-out port while contacting one edge side of the banknote bundle to convey the banknote bundle toward the pay-out port. The banknote pay-out device also includes a shutter opening-and-closing projection that, as the push-out plate moves toward the pay-out port, moves together with the push-out plate and moves the shutter toward an opening direction to open the pay-out port.

A medium conveyance device is provided including a placement body, a Scott-Russell body, a moving section, and a conveyance state switching section. The placement body includes a bundle conveyance face on which a medium bundle configured by stacking plural medium into a bundle shape is conveyed in a state placed on the bundle conveyance face. The Scott-Russell body includes an abutting portion that abuts the medium bundle. The movement section causes at least a portion of the Scott-Russell body to abut against the medium bundle and moves the Scott-Russell body along the bundle conveyance face in a first direction, or in a second direction opposite to the first direction, so as to move the medium bundle along the bundle conveyance face in the first direction or in the second direction. The conveyance state switching section utilizes the Scott-Russell body being moved by the movement section to switch to a first conveyance state in which at least a portion of the Scott-Russell body is caused to abut against the second direction side of the medium bundle and conveyance of the medium bundle toward the first direction is enabled, or to a second conveyance state in which at least a portion of the Scott-Russell body is caused to abut against the first direction side of the medium bundle and conveyance of the medium bundle toward the second direction is enabled.

A media processing apparatus includes a media transporter, a stacking portion on which media are stacked, a binding processing portion that binds an upstream end portion of a media bundle, a pair of ejection rollers that eject the media bundle, and a displacement mechanism that displaces a first roller of the pair of ejection rollers to a nipping position at which the media bundle is nipped and a separated position at which the first roller is separated from the media bundle, in which, when the media bundle, the upstream end portion of which is closed, is to be ejected from the stacking portion, the first roller is disposed in the nipping position and ejection of the media bundle is started, the first roller is displaced to the separated position during ejection of the media bundle, and, thereafter, the first roller is disposed again at the nipping position.

A medium aligning apparatus includes a load tray including a load surface on which a medium discharged from a discharge member that discharges a medium is loaded, a first aligning surface that aligns a plurality of mediums loaded on the load tray by positioning rear ends of the mediums, and a second aligning surface that aligns the mediums by positioning the rear ends of the mediums loaded on the load tray. In the medium aligning apparatus, the first aligning surface and the second aligning surface are switchable, and an angle formed between a wall surface in the discharge tray that receives the mediums discharged from the load tray, the wall surface having the rear ends of the mediums come in contact therewith, and the second aligning surface is smaller than an angle formed between the wall surface and the first aligning surface.

A sheet alignment device includes a driven roller, a drive roller, a displacement driving device, an information acquisition portion, and a displacement control portion. The drive roller is configured to rotate in a first rotation direction and in contact with an upper surface of each of sheets conveyed onto a tilt tray, to feed the sheets toward a base end portion of the tilt tray. The drive roller is configured to rotate in a second rotation direction and in contact with an uppermost surface of the sheets, to discharge the sheets from the tilt tray. The displacement control portion is configured to, when the drive roller rotates in the first rotation direction, control a holding position of the drive roller in accordance with the number of the sheets on the tilt tray and thickness information of each of the sheets acquired by the information acquisition portion.

According to an embodiment, a sheet processing apparatus includes a transport unit and a holding unit. The transport unit transports a first sheet to a first position. The transport unit transports a second sheet, which is transported after the first sheet, to a second position displaced to the upstream side of a sheet transport direction relative to the first position. The transport unit transports a third sheet, which is transported after the second sheet, to a third position displaced to the downstream side of the sheet transport direction relative to the second position. In the case where the second sheet is transported to the second position, the holding unit holds the first sheet at the first position. In the case where the third sheet is transported to the third position, the holding unit holds the second sheet at the second position.

A sheet post-processing device comprises: a processing tray; a discharge tray; and a discharge rollers pair. The discharge rollers pair is constituted by a discharge roller which contacts the uppermost surface of sheets stacked in the processing tray and a discharge roller which contacts the lowermost surface of the sheets stacked in the processing tray). The sheet post-processing device discharges a sheet from the processing tray to the discharge tray by rotating the discharge rollers pair in the forward direction, and causes the sheet to be drawn into the processing tray by rotating the discharge roller in the reverse direction in a state in which the rotation of the discharge roller is stopped.
