Abstract

A sheet storing apparatus wherein sheets ejected from a copying machine one after another are stacked in order, and the sheets are supplied to the copying machine again. The apparatus comprises a sheet storing unit wherein sheets are stored, a transporter for transporting sheets to the storing unit, a regulator for preventing sheets supported by a sheet support surface of the storing unit from moving back toward the entrance thereof, a pressure member for pressing each sheet transported to the unit against the support surface and a refeeder for feeding out the stored sheets one by one. Each time a sheet is transported to the unit, the pressure member presses the sheet, whereby the end of the sheet passes through the regulator to be put between the support surface and the regulator. Also, in feeding sheets out of the unit, the pressure member presses the sheet stack against the refeeder. The pressure member has a mechanism for adjusting the pressure on the sheet stack in proportion to the thickness of the stack. Each time a sheet is transported to the unit, the timing of actuating the pressure member is determined, and the position of the pressure member is detected. When it is not …
