摘要： A recirculating document feeder for use with an image forming machine having a transparent platen. This recirculating document feeder includes a document support disposed above the transparent platen and adapted to have a stack of documents placed thereon, with a selected side of each document facing down; a feed-out path extending from one end of the document support; a first switchback path having an upstream end connected to the downstream end of the feed-out path; a send-in path extending from its upstream end, which is connected to the upstream end of the first switchback path, to one end of the transparent platen; a send-out path extending from the other end of the transparent platen; a second switchback path having an upstream end connected to the downstream end of the send-out path; and a return path extending from its upstream end, which is connected to the upstream end of the second switchback path, to the other end of the document support. The bottom-most document of the document stack placed on the document support is fed out to the feed-out path, fed to the first switchback path through the feed-out path, and then sent onto the transparent platen through the send-in path in a reversed direction of feeding. Then, the document is fed from the transparent platen to the second switchback path through the send-out path, and then returned onto the document stack on the document support through the return path after the direction of its feeding is reversed again.
