Abstract: The present invention is to provide a sheet discharge device capable of preventing the lowermost sheet on a tray from being displaced. A present sheet post-processing device includes a first tray for stacking a sheet, a processing tray that temporarily stacks conveyed sheets until a number of the sheets reaches a predetermined number, and a discharge mechanism that discharges the sheets stacked on the processing tray onto the first tray. A sheet bundle forming unit divides, when forming a first sheet bundle on the first tray, sheets constituting the first sheet bundle into a plurality of sets and discharges the sheets a plurality of times for each set. At this time, a number of sheets included in a sheet set to be discharged at the first time is smaller than a maximum number of sheets included in sheet sets to be discharged at the second and subsequent times.

Abstract: A sheet conveying device includes a discharging roller pair, a discharge sheet holding portion, and a stopper member. The discharging roller pair discharges the sheet member outside from a sheet discharge port by rotating in a forward rotational direction. The discharging roller pair includes a first conveying roller, and a roller member. The discharge sheet holding portion is for holding the sheet member discharged outside by the discharging roller pair. The stopper member is swingably supported on a rotational shaft of the first conveying roller. The stopper member allows the sheet member to be discharged to the discharge sheet holding portion when the discharging roller pair rotates in the forward rotational direction, and prevents the sheet member from intruding into the nip portion from the discharge sheet holding portion when the discharging roller pair rotates in the reverse rotational direction.

Abstract: A sheet discharge apparatus includes: a discharger that discharges a sheet; a loading part on which the sheet discharged from the discharger is loaded; an abutment member that abuts against a rear end of the sheet in a direction of discharging to align the sheet loaded on the loading part; a pull-back member that performs a pull-back operation by contacting with the sheet discharged from the discharger to pull back the sheet toward the abutment member; and a hardware processor that controls the pull-back member. The hardware processor performs the pull-pack operation on a sheet bundle when determining that the sheet bundle bound by a binder is discharged from the discharger.

Abstract: A sheet discharge device has a sheet discharge port, a conveying guide, discharge roller pairs, corrugation members, and first biasing members, and discharges sheets onto a discharge tray sequentially. The corrugation members are arranged between the discharge roller pairs to protrude beyond a nip portion in them and stiffens the sheet by pressing one side of the sheet. The first biasing members bias the corrugation members in the protruding direction. Each of the corrugation members has, in a region extending from the upstream side to a downstream-side end part of the discharge roller pairs in the sheet discharge direction and including the nip portion, a first pressing part making contact with one side of the sheet and, in a region further on the downstream side of the downstream-side end part of the discharge roller pairs, a second pressing part making contact with one side of the sheet.
