<p>PURPOSE: To provide a sheet post-processing device smoothly performing staple operation by preventing sheet extrusion by means of a stapler. CONSTITUTION: A sheet post processing device is provided with sheet pressing means 160 for pressing sheet ends on bins B2 , B3 having perforated predetermined intervals (opening parts X1 , X2 ) by means of a lead cam 51 on stapling by means of a stapler 56. Thus, the sheet on the bins B2 , B3 having the perforated predetermined intervals (the opening parts X1 , X2 ) is not extruded by means of the stapler 56 to smoothly perform post-processing operation, such as sheet binding.</p> |
