PROBLEM TO BE SOLVED: To solve the problem of the fear of breaking the uppermost sheet of the discharged sheaf of sheets due to the characteristic of the discharged sheaf of sheets, in discharging a sheaf of sheets to a discharge tray. SOLUTION: In discharging a stapled sheaf 80 of sheets to an offset tray 11, according to the sheet sheaf characteristic, the lift amount on the forward end side in the discharge direction is adjusted by a lift mechanism 76 to discharge the sheaf of sheets.
