A post-processing unit includes a stapler, a driving section, and a controller. The stapler is moved in a Y direction and executes a stapling process on a paper sheet. The driving section moves the stapler in the Y direction. The controller controls an operation of the stapler and an operation of the driving section. The controller executes first control to supply a set current or a set voltage to the driving section, second control to supply, to the driving section, the same supply current as the set current or the same supply voltage as the set voltage, and third control to stop the supply of the supply current or the supply voltage. When the stapler executes the stapling process a plurality of times, the controller repeatedly executes the second control and the third control and causes the stapler to execute the stapling process during the execution of the second control.

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.

Media processing apparatus and recording apparatus

Provided are a placement table configured to place a medium onto which liquid is discharged, a perforation member configured to perform perforation by imparting a shear force to the medium placed at the placement table, a die hole provided at the placement table, a perforation member moving section configured to move the perforation member between a standby position above the die hole and a perforating position at which the perforation member enters the die hole, and a control unit configured to control operation of the perforation member moving section, wherein when the control unit obtains perforation failure information during perforating operation in which the perforation member starts moving from the standby position and moves through the perforating position to the standby position, the control unit is configured to control the perforation member moving section so that a shear force is again imparted to the medium.

Post-processing device and liquid discharge device

A medium discharging device includes a paper discharging tray that is disposed below a height position of a discharging roller which discharges a medium and includes a placing surface on which the medium discharged by the discharging roller is placed, and a supporting member that is configured to be movable between a retreat position on an upstream side and an advance position on a downstream side between the discharging roller and the placing surface.

Medium discharging device

A medium discharging device includes a discharge roller pair that discharges a medium, a discharge tray disposed below the discharge roller pair in a vertical direction and having a placement surface on which the discharged medium is placed, and a guide member that is advanced and retracted between an advanced position where the guide member is advanced inward in a width direction from opposite sides in the width direction intersecting a discharge direction of the medium and a retracted position where the guide member is retracted to an end portion position side in the width direction. When the guide member is disposed at the advanced position, an upstream side end portion of the guide member in the discharge direction is disposed between a discharge position by the discharge roller pair and a position of the placement surface of the discharge tray, in the vertical direction.
