ABSTRACT:
A copying machine includes a copying unit, an automatic original feeding unit, and a sorting unit. The sorting unit includes discharging rollers and a tray unit. The tray unit is detachable to a main body and includes a plurality of trays which are detachably connected to the tray unit. The discharging rollers are located in the main body and moves upward and downward. The sorting unit further includes a tray detecting device which detects the position of a tray of the tray unit. Before the copying unit makes a copy, the detecting device detects the tray unit and each tray of the tray unit. When one of the trays is detected, a CPU memorizes the position of the tray and controls the discharging rollers to move upward or downward to the position facing the tray of the tray unit. A sheet from the copying unit is conveyed to the sorting unit. The sorting unit includes a pair of guide plates which define a guide path. The length of the guide path will vary according to the position of the tray in which the sheet is to be discharged.
