COPIER DOCUMENT HANDLING SYSTEM

摘要

COPIER DOCUMENT HANDLING SYSTEM OF THE SPECIFICATION A low cost original document handling apparatus for a copying machine for automatically discharging the original document from the platen after it has been copied. It is automatically driven for an electrically controlled time period by a helical spring drive system which automatically stores and subsequently utilizes the platen cover opening or closing force to eject documents and eliminate the cost and power consumption of a conventional electrically driven document drive system. It includes automatic over-winding protection. A dual function electromechanical release system automatically unlatches the platen cover after connecting the spring drive to eject the document.
