Abstract
A sheet collecting apparatus has a sheet discharge outlet, a tray device for bearing and storing sheets, a regulation stopper disposed in the tray device; a forward/backward rotation roller, a roller lifting/lowering device, a sheet pressing guide disposed between the forward/backward rotation roller and the regulation stopper; a pressing force reducing device for reducing a pressing force, and a control device for controlling the forward/backward rotation roller, the roller lifting/lowering device and the pressing force reducing device. The control device is configured to rotate forward the forward/backward rotation roller in the operating position to move forward a carried-in sheet in the sheet discharge direction by a predetermined distance, and then rotate backward the forward/backward rotation roller. The control device has two operation modes that are selectively executed a first operation mode and a second operation mode.
