  • Patent number: 5012297
    Abstract: A sheet storing apparatus comprising a tray for receiving sheets ejected from a copying machine, a first shift unit for reciprocating the tray in the direction perpendicular to the ejection of sheets, an aligning member for aligning the sheets on the tray, which is in contact with the surface of the top of the sheets on the tray and a second shift unit for shifting the aligning member in the same direction as that of the shifting of the tray. The sheets are divided by the shifting of the tray every time a set of sheets finishes to be transported onto the tray, and the aligning member is shifted synchronized with the shifting of the tray.

  • Patent number: 4973036
    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.
