Abstract: Disclosed is a paper feeder for sequentially feeding laminated cutform paper to a record/write portion or the like. Proper sagging of the cutform paper is produced on this side of a paper feeding roller during rotations of the paper feeding roller in an anti-feeding direction, thus adjusting the direction thereof. Subsequently, with rotations of the paper feeding roller in a paper feeding direction, a feed roller is temporarily rotated. The paper feeding roller is caused to exactly pull in the cutform paper without exerting abrupt fluctuations in load on the paper feeding roller and the cutform paper.

Abstract: A switch is located near a pair of register rollers for feeding a document sheet toward a platen glass. A pair of document-feeding rollers are located near a platen glass.

Abstract: In the document feeder of the invention, the originals stacked in the document hopper always show the same surfaces upward during copy operation. Consequently, when an original document sheet causes paper jam or similar trouble in the transport path, the original may be restacked in the document hopper with the same surface facing upward as that facing upward when the original was first stacked in the document hopper. Consequently an operator is less likely to be confused as to the surface to face upward when stacking originals in the document hopper, resulting in improved operating performance. Further, the structure of installing the original feeding mechanism and the original restacking mechanism separately on both sides of the document hopper and bottom-feed, top-restack configuration of the document hopper simplifies the structure around the document hopper.
