<p>PURPOSE:To eliminate a failure in shaking a bin, ensure the trued-up of sheets in the bin, and realize a stable stapling by a method wherein a plurality of reference surfaces for truing up the rear ends of sheets contained in a shakable bin are separately disposed on a part of an inner wall of the shakable bin and a part of a fixed wall for stopping the bin. CONSTITUTION:A sorter is provided with a plurality of bins 41 for sorting and containing sheets P delivered from an image forming device body 1; bin shaking devices 70 for shaking the bins 41 for moving the contained sheets P to stapling positions; and stapler devices 80 for stapling the sheets P. A plurality of reference surfaces on which the rear ends of the sheets P contained in the bin 41 per size are abutted to be trued up are separately disposed on a part of an inner wall of the shakable bin 41 and a part of a fixed wall for stopping the bin 41 at a predetermined position.</p> |
