<p>PROBLEM TO BE SOLVED: To store a large volume of post-processed sheets on a paper discharge tray by elevating/lowering a paper discharge tray means when a sensor detects that the volume of the sheets discharged and loaded on one paper discharge tray means reaches the prescribed maximum value, and discharging and loading the sheets on the other paper discharge tray means. SOLUTION: When the post-processed sheets P are drawn from other paper discharge tray means, i.e., the paper discharge tray means 20 on the upper stage during or after the sheet post-processing, the self weight of the sheets P on a movable paper discharge pan 21 is reduced, the movable paper discharge pan 21 is urged by a spring, and elevated, and a sensor PS1 or PS3 generates the signal of loading the sheet P is possible, and continues the sheet post- processing after the paper discharge tray means is moved. The sheet post- processing operation is continued by arbitrarily drawing the post-processed sheets P on the upper and lower paper discharge tray means 20, 30 during the post-processing of the sheets, and a large volume of sheets P can be post- processed.</p> |
