<p>PURPOSE:To freely change the shape of the sheet receiving face of a discharge tray according to the processing mode, easily match sheets, and improve the post-processing work efficiency of sheets by providing an auxiliary tray protrudable on the sheet receiving face on the discharge tray. CONSTITUTION:The sheet post-processing device of a copying machine is provided with a post-processing conveyance path 42 conveying copied sheets and a processing discharge path 44 stapling and discharging them to a discharge tray 45 on the downstream side. A sheet receiving face 45a recessed from the virtual line on the extension line of a stapling plate 44a is formed on the upper face of the discharge tray 45, and a horizontal section 45c is formed on the aligning plate side of the sheet receiving face 45a. A bore hole 45b is formed on the sheet receiving face 45a side, and an auxiliary tray 56 is protrudably provided. A solenoid 59 is turned off in the stapling mode, and the auxiliary tray 56 is controlled to wait at a position on the extension line of the stapling plate 44a by the force of a torsion spring 62.</p> |
