A bill processing apparatus which is capable of reliably supplying information on a bill to the bill housing body side. The paper sheet processing apparatus has a bill housing part (100) being capable of housing a bill inserted from a bill insertion slot, and also a reader/writer (142) which wirelessly transmits information on the bill inserted from the bill insertion slot. The bill housing part (100) has a coil antenna (104c) which wirelessly receives the information transmitted from the reader/writer (142), and a storage part (104b) which stores the information on the bill received from the coil antenna (104c).

A medium conveyance device includes a first loading base that has a first loading surface formed thereon and is movably supported on a main body, a second loading base that has a second loading surface formed thereon and is movably supported on the first loading base so that the second loading surface is positioned next to with the first loading surface and so that the second loading surface overlaps with the first loading surface, a mechanism that converts motion of the first loading base into motion of the second loading base so that the second loading base is arranged in a position corresponding to a position in which the first loading base is arranged, and an elastic member that is elastically deformed when the second loading base is not arranged in a position corresponding to a position in which the first loading base is arranged.

A medium ejection apparatus includes a placement mount on which media are placed, a restriction part that moves between a restriction position at which the restriction part restricts media ejected toward the placement mount and a retracted position retracted from the restriction position, and a processor that controls the restriction part by adjusting a restriction frequency on the basis of at least either an amount of movement of the restriction part from the retracted position to the restriction position or ejection intervals at which the media are ejected toward the placement mount, the restriction frequency being a frequency with which the restriction part performs a restriction operation for the media.

An image forming apparatus that is capable of reducing influence of a failure on execution of a print job even if a post-processing apparatus that has a sheet stacking unit breaks down. Post-processing apparatuses are connected at a downstream side of an image forming apparatus in a sheet conveyance direction and apply post-processes to the sheet discharged from the image forming apparatus. A specifying unit specifies an available downstream-most apparatus from among the post-processing apparatuses. A setting unit can set a forced discharge mode in which a sheet is discharged to the downstream-most apparatus when the downstream-most apparatus is not provided with a sheet stacking unit. When the forced discharge mode is set, apparatuses at an upstream side of the downstream-most apparatus are controlled so as to discharge a sheet to the downstream-most apparatus and the downstream-most apparatus is controlled so as to discharge the sheet outside the apparatus.

A flange portion extending outward from a main shaft portion is disposed outside a side plate with respect to a position of an attachment member in a main direction when the attachment member is mounted to the side plate. A restriction slot is formed in the attachment member such that the flange portion can be fitted in and pass through the restriction slot. In the middle of the process where the attachment member is mounted to a second side plate in the main direction, the flange portion is fitted in the restriction slot, thereby the sheet detecting member is restricted from rotating, and one of a pair of projection portions of a sheet guide member is inserted in a hole of the attachment member.

An image forming apparatus includes a discharging tray for supporting a sheet, an operation panel and a supporting member. The sheet is discharged toward a sheet discharging direction that is a direction toward which the sheet is discharged. The operation panel is located at a position which is different from the position of the discharging tray in a width direction orthogonal to the sheet discharging direction and above the discharging tray. The supporting member is disposed at the discharging tray and capable of supporting the discharged sheet with the discharging tray. A front end portion of the supporting member is located above an upper surface of the discharging tray. At least a part of the front end portion of the supporting member overlaps the operation panel when viewed in the width direction.
