A sheet discharging apparatus includes a stacking portion, a first conveyance portion, a detection portion, a second conveyance portion, a third conveyance portion, and a control portion. The control portion is configured to execute a discharge operation by causing the sheet discharging apparatus to reverse a conveyance direction of a first sheet conveyed from the first conveyance portion to the second conveyance portion and deliver the first sheet to the third conveyance portion by using the second conveyance portion, convey the first sheet toward the second conveyance portion by the third conveyance portion, and discharge the first sheet and the second sheet to the stacking portion by using the second conveyance portion in a state where the first sheet and the second sheet are superimposed on each other.

Sheet discharging apparatus, sheet processing apparatus, and image forming system

A sheet processing apparatus includes a discharge unit, a loading unit, an abutting unit, a support unit, and a control unit. The discharge unit discharges, from a discharge port, a sheet bundle transported along a transport path. The loading unit is loaded by the sheet bundle being discharged onto the loading unit. The abutting unit is disposed forward from the discharge port in a discharge direction of the sheet bundle so that the abutting unit abuts with a top surface of the discharged sheet bundle. The support unit is protrusible from and retractable into the discharge port and protrudes to an underside of the sheet bundle temporarily to support the sheet bundle when the sheet bundle is discharged. The control unit controls movement of the support unit such that the support unit reaches a position of the abutting unit after the sheet bundle abuts with the abutting unit.

Sheet processing apparatus and image forming system

A sheet processing apparatus includes a first sheet conveyance path, a second sheet conveyance path that branches from the first sheet conveyance path at a branch portion on the first sheet conveyance path and merges with the first sheet conveyance path at a merging portion, and a control unit. The control unit controls a guide unit so as to guide a first sheet conveyed first in the sheet bundle to be processed by a sheet processing unit to the second sheet conveyance path, and guide a second sheet following the first sheet to the first sheet conveyance path to merge the first and second sheets in an overlapping manner at the merging portion, and guide at least one of sheets following the second sheet among a plurality of sheets constituting the sheet bundle to the second sheet conveyance path.
