PURPOSE:To facilitate maintenance operation, and to eliminate the need to provide unnecessary space in a copying machine frame by drawing a subassembly and extending the stroke, if necessary. CONSTITUTION:When a subassembly 9 is drawn out fully in a forward direction by holding a grip 10, normal operation by an operator is carried out. To further draw the subassembly out, a screw 8 is removed and the grip 10 is drawn, and thus the subassembly is drawn as long as the long-sized hole 7 of a supporting bracket 7. To store the subassembly 9 in the frame of the copying machine, the subassembly 9 is pressed forward, supporting brackets 4 and 6 are fixed mutually with the screw 8, and the subassembly is further pushed forward. Therefore, maintenance operation is facilitated and the need to provide unnecessary space in the copying machine frame is eliminated.
