ABSTRACT:
An apparatus for automatically and circulatively feeding originals comprises an original feed-out section for sequentially feeding out the originals stacked therein from an original placed at a lowermost position, each image to be copied of the stacked original being kept facing downwardly, and an original reversing section provided with a reversing roller for reversing the direction of movement of the original exposed at an original exposure section. In the case of both-side copy, the exposed original is guided through a first reversing path in the direction of the original feed-out section by means of clockwise rotation of the reversing roller, and in the case of single-side copy, the exposed original is guided through a second reversing path in the direction of the original feed-out section by means of counterclockwise rotation of the reversing roller.
