<p>PROBLEM TO BE SOLVED: To miniaturize an entire machine so as to conserve space by setting the longitudinal direction dimension of a staple tray for loading paper sheet bundles to be shorter than the carrying direction length of a maximum size copying paper sheet in a device for perform binding after a plurality of copying paper sheets are housed in aligned. SOLUTION: Copying paper sheets passed between upper and lower relay guiding plates 201 and 202 and carried into a paper sheet post-treatment device 100 are sent between a carrying guiding plate 206 and an entrance guiding plate 205 by a feed roller 203 and, at this time, if a staple mode is selected, when paper sheet tips are detected by an entrance sensor 204, a branch catch 208 is rotated to a position 208a by the operation of a solenoid. Thus, the paper sheets are ejected to a staple tray 401 by a feed roller 207. Thus, in a post- treatment device, by setting the longitudinal dimension of the staple tray 401 to be shorter than the feeding direction length of a loaded maximum size paper sheet, an entire machine is miniaturized to conserve space.</p> |
