Abstract: A media stacker (100) comprises a stacking platform (102), a feed mechanism (104), a media arresting mechanism (106) and a controller (108). The feed mechanism conveys media sheets for dispensing onto the stacking platform, wherein the media sheets are dispensed onto the stacking platform with a momentum imparted by the feed mechanism. The media arresting mechanism reduces the momentum of media sheets. The controller determines that a trailing edge of a media sheet is to be dispensed onto the stacking platform, and further control the media arresting apparatus to reduce the momentum of the media sheet in response to the determination.

Abstract: A sheet post-processing apparatus includes a sheet introducing unit, a first sheet discharge unit, a second sheet discharge unit, a sheet processing unit, a sheet conveyance unit, and a control unit. The first and the second sheet discharge unit are configured to be able to discharge a sheet to an outside. The sheet conveyance unit includes a sheet conveyance path arranged between the first sheet discharge unit and the second sheet discharge unit. The control unit controls the sheet conveyance unit to convey the sheet along the sheet conveyance path toward the first sheet discharge unit to a predetermined position at which the sheet is not discharged from the first sheet discharge unit to the outside, then convey the sheet along the sheet conveyance path in an opposite direction toward the second sheet discharge unit, and discharge the sheet from the second sheet discharge unit.

Abstract: A sheet processing apparatus is provided with a carry-in path for guiding a sheet from a carry-in entrance, a shift roller provided in the carry-in path to transport the sheet, while shifting, a carry-in roller positioned on the downstream side of the shift roller to carry the sheet from the carry-in path toward a collection tray, and a punch shift unit provided on the upstream side of the carry-in roller to process an end portion of the sheet in a processing position. The punch shift unit shifts in the same direction as the shift roller, a shift amount of the punch shift unit is set to be equal to a shift amount of the shift roller or more, and the end portion processing unit is thereby already positioned in an end portion processing position or a position near the processing position after shifting the sheet.
