Abstract
A sheet processing apparatus capable of improving sheet processing performance and productivity is provided. While sheets are conveyed in a piled state toward a rear-end stopper, displacement is produced between the sheets by a pair of discharge rollers. Even if adhesion occurs between the sheets during conveyance thereof, the adhesion between the sheets can be removed before the sheets come into contact with the rear-end stopper.
Claims3
A sheet processing apparatus comprising:
- a conveying portion, having a pair of conveying rotary members, capable of conveying a plurality of sheets in a piled state;
- a stacking tray on which sheets, conveyed by the conveying portion are stacked;
- a regulation member against which piled sheets are abutted to regulate the sheet conveyed to the stacking tray,
- a changing portion which changes inclination of a line that connects centers of rotations of the pair of conveying rotary members;
- and
- a control portion which controls the changing portion, the control portion controlling the changing portion so that displacement of the piled sheets in a sheet conveying direction occurs by changing the inclination of the line connecting the centers of the rotations before the piled sheets are abutted against the regulation member.
