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.
