发明名称 ANTI SLIP BACK ROLLERS IN A REVERSIBLE BELT FEEDER
摘要 <p>There is provided a document handling apparatus for use in copying machines. The apparatus is of the type wherein sheets are moved in sequence automatically into a registered position on a work surface and then are moved out of that position to make way for the next sheet. The apparatus is designed to overcome the problem of a document being only partially ejected and then being fed back onto the platen. The apparatus includes a document driving belt that can be driven in both directions. A pair of document driving rotary members flank the belt and are driven in one direction only.</p>
