ABSTRACT:
A paper feed device to forward documents to be copied across a document glass utilizing foraminous rollers positioned above the glass at a slight angle to the direction of document movement to move the side of the document into sliding relationship with a reference edge during the forwarding operation. The angle is produced by a curved drive shaft and rollers at opposite ends of the drive shaft are at different angles to the direction of paper movement. The rollers and drive train are rigidly mounted on a plate which is nonrigidly carried in a frame which pivots about a hinge at one end of the document glass. The plate rests on the top surface of front and rear reference edges when the frame is closed to assure accurate positioning of the rollers in relation to the document glass. After completing the forward feeding of a document, it is reversed a slight distance to a registration position for the copying operation.
