Abstract
A document feeder for recirculating simplex or duplex document sheets to and from a scanning station of a reproduction apparatus for selectively producing pre-collated or post-collated simplex or duplex copies of simplex or duplex document sheets. The document feeder includes a first document sheet transport path extending from a hopper to the scanning station; a second transport path located in juxtaposition with the scanning station for moving a document in scanning relation to such station; a third transport path, for turning a document sheet over, located between the hopper and the second transport path; and a fourth transport path extending between the second path and the hopper. A drive mechanism, associated with the transport paths, is operative to transport a sheet in a particular direction along such respective paths. A first diverter is controlled to be located in a first position for directing a transported document sheet from the first path to the third path when document sheets are of the simplex type, and in a second position for directing a transported document sheet from the first path to the second path when document sheets are of the duplex type. A second diverter is controlled to be located in a first position for retaining a transported document in the second path for recirculation past the scanning station when post-collated copies are to be made, and in a second position for directing a transported document sheet from the second path to the fourth path when pre-collated copies are to be made.
