To provide a post-processor capable of executing alignment processing with high accuracy. Configuring a post-processor including: a recording material loader on which a recording material conveyed through a conveyance path is loaded; an aligner that aligns the recording material in the recording material loader; a driver that moves the aligner; and a controller that receives information of a physical property value of the recording material acquired by a medium sensor and determines an operation parameter of alignment processing that drives the driver based on the information of the physical property value.

A feeding device comprises a suction feeding unit having a belt for feeding a sheet in a suction state and a belt driving unit, a sheet detection sensor, and a control unit. The control unit controls the belt drive unit so as to feed the sheet in a feeding direction at a first speed. If the sheet does not arrive at the sheet detection sensor, the control unit controls the belt drive unit so as to execute a low-speed feeding of moving the belt in the feeding direction at a second speed lower than the first speed or so as to execute a reverse feeding of moving the belt in a reverse feeding direction opposite to the feeding direction.

A paper sheet storage apparatus (1) includes: a placement mount (10) on which bills (B), i.e., an example of paper sheets, are placed; a leading-edge position restriction guide (20) that restricts the position of the leading edge portion of a bill (B) in an entering direction (D) in which the bill (B) advances when being transported onto the placement mount (10); and a sensor (30) that detects the presence/absence of an accumulation space (S) for bills (B) that is located above the placement mount (10). The sensor (30) detects the presence/absence of an accumulation space (S) by using detection light (L) emitted to a space between a first position (P1) that is located on an opposite side of the leading-edge position restriction guide (20) from the bills (B) on the placement mount (10) and a second position (P2) below the first position (P1) that is located on an opposite side of the bills (B) on the placement mount (10) from the leading-edge position restriction guide (20).

A sheet conveying device includes a corrector configured to correct a position of a sheet, and at least three detectors disposed in a sheet conveyance direction. Each of the at least three detectors is configured to detect a lateral end of the sheet according to a length of the sheet to be conveyed in the sheet conveyance direction. The corrector is configured to correct the position of the sheet based on detection results of each of the at least three detectors.

In some examples, the disclosure describes a device that includes a first media tray positioned at a media input of a pick and separation mechanism, a second media tray positioned at the media input of the pick and separation mechanism, a media scan guide to position a sheet of print media at the media input of the pick and separation mechanism, a shared media path comprising a turn roller to receive the sheet of print media from the pick and separation mechanism from a first direction and provide the sheet of print media to a print zone in a second direction, and an output zone to receive the sheet of print media from the shared media path.
