<p>PURPOSE:To provide a sheet after-treatment device, having a chuck device capable of preventing rotation due to the own weight of a sheet bundle even without the guide part in a bin rear end in moving the sheet bundle in parallel to a sheet discharge direction, performing good sheet binding, and equipped with a simple and inexpensive sheet-binding apparatus. CONSTITUTION:This device is provided with a chuck apparatus 440, having two pairs of sheet bundle nipping members, having a fixed interval in parallel to the discharge direction of a sheet, and nipping a discharged sheet bundle to lead it to a sheet binding apparatus 470. Since the sheet binding apparatus 470, moved in parallel along the rear end sides of plural bins 350 and rotationally moved in this side end surface, is provided, plural binding methods can be selected in binding sheets, loaded on respective bins 350, by the sheet binding apparatus 470.</p> |
