Abstract
A copying apparatus includes an image forming device, a sheet reversal mechanism, and a sheet holding device having a tray, each of the components being independently separable. The sheet reversal mechanism transports to the tray each sheet either in face-up condition or with its face turned downward. The tray is lowered according to the volume of sheets loaded thereon and is caused to shift on a horizontal plane under a specified timing control. The lowering of the tray is effected through detection by a sensor of the volume of sheets loaded on the tray. After each such lowering, any downward movement of the tray is inhibited until a next sheet is loaded on the tray.
