POSTPROCESSING DEVICE, IMAGE FORMING SYSTEM, AND PAPER PUNCHING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a postprocessing device which allows arbitrary adjustment of a punching position and eliminates variation of the punching position.

SOLUTION: The postprocessing device comprises a second conveying roller 12 which is arranged on the downstream side in the paper conveying direction of a punching means 30 and grips and conveys a paper sheet S, a movable pressing member 48 which is arranged on the upstream side in the paper conveying direction of the punching means 30, presses the rear end (a) in the paper conveying direction of the paper sheet S, and pushes out it in the conveying direction, and a control means 100 for controlling the driving of the second conveying roller 12 and the pressing member 48. The control means 100 controls the stop of the paper tip of the second conveying roller 12 and push out of the rear end of the paper sheet by the pressing member 48, and variably adjusts the punching position in the paper conveying direction.
