Copy sheet feed device

Claim 1

A copying apparatus for performing a duplicating operation on an original document comprising: (a) an original document scanning means for scanning and transmitting an image of an original document to be duplicated, said scanning means comprising movable means for reciprocal movement along a scanning path defined by the limits of image transmission; (b) receptor means for receiving said transmitted image and producing an intermediate image of the original document in response thereto, said receptor means comprising an endless surface moving cyclically along a fixed path continuously at a predetermined rate during the duplicating operation, on which surface said intermediate image is produced; (c) a copy sheet feed means for presenting copy sheets to said surface containing said intermediate image in order to transfer said intermediate image of said original document onto said copy sheets; (d) detection means disposed in a predetermined position along the scanning path of said movable means, for detecting the movement of said movable means past the predetermined position and for producing a detection signal in response thereto; and (e) means for actuating the copy sheet feed means in response to said detection signal; and wherein said predetermined position is set along the scanning path of said movable means such that the detection signal is synchronized to cause said copy sheet feed means to feed the leading end of each copy sheet to said surface in coincidence with the leading end of the intermediate image.
