<p>PROBLEM TO BE SOLVED: To provide a sheet posterior processing device capable of applying to an inexpensive system, stabling discharge performance and stack performance of a sheet bundle discharged after staple processing, and corresponding to various size of a sheet. SOLUTION: When a sheet posterior processing device receives a start-up signal from an image forming device to start action, both of a jogger fence 70 and a staple fence 72 move to a position parting from a sheet end surface discharged with a central standard by a specific distance (10 mm) to stand by. (a) Then, the jogger fence 70 moves toward the staple fence 72 by only 20 mm and conducts a shifting action of the sheet to justify the sheet. (b) In such a way, since only the jogger fence 70 of one side is operated to conduct a justifying action of the sheet, an operating load is less than usual, so that a driving system of the jogger fence 70 can be made at low prices.</p> |
