Abstract
A stapler processing apparatus includes a paper jogging tray 6 for a collated sheet 3, a paper jogging unit 7 for jogging the collated sheet 3 by pressing it on the tray 6 by a presser jogging member 13, a stapler 8 for stapling the collated sheet 3 jogged by the paper jogging unit 7 and a paper discharging unit 9 for discharging the collated sheet 3 stapled by the stapler 6 from the tray 6. In operation, when the stapler 8 staples the collated sheet 3, it is forced to the tray 6 while making an upper driven roller 30b in close contact with a lower drive roller 30a. After stapling by the stapler 8, the paper jogging operation of the paper jogging unit 7 is stopped and the upper driven roller 30b is separated from the lower drive roller 30a to release the collated sheet 3 from it nipped state once. Subsequently, the upper driven roller 30b is brought into close contact with the lower drive roller 30a again and the discharge operation is started.
