Abstract
In order to execute the duplex copying operation, a sheet re-feeding apparatus transports sheets having an image formed with an image-forming apparatus one by one into a cassette through a transporting means, and then re-feeds the sheets one by one from the cassette into the same image forming apparatus. The transporting means catches a sheet with rollers and allows the sheet to be widthwise curved, whereby the sheet is transported into the cassette. A plurality of cassettes is prepared in accordance with sheet sizes and is detachable from a main body of the sheet re-feeding apparatus. Inside the cassette are disposed a projection to stack and store a sheet in a condition where the sheet is widthwise curved, stoppers separated by a space approximately equal to the width of a sheet, pressing means for pressing both side portions of a sheet, means for regulating the leading edge of a sheet, a flexible member for catching the leading edge of a sheet together with a stacking surface, and the like.
