Abstract
Abstract A sheet handling apparatus comprising a stapling tray for receiving sheets ejected from a copying machine and a stamp for stamping on the sheets in the stapling tray, wherein the surface of the stapling tray facing the stamp is made of soft and elastic material to reduce friction. The sheets are selectively stapled or stapled and stamped, and the stamping operation is performed after the stapling operation. Further, the sheet handling apparatus comprises an ejection tray for receiving sheets ejected for the copying machine, an elevate block for elevating and lowering the ejection tray, a linking mechanism for actuating the stamp to stamp on the sheets in connection with the movement of the ejection tray driven by the elevate block.
