    摘要: An improved recirculating document feeder (12) for presenting sheets from a document sheet stack (S) seriatim to a station (14) of a reproduction apparatus (10) for reproducing information contained on such document sheets. The improved recirculating document feeder comprises a support (18a) for a document sheet stack, with a selected side of each document sheet facing up and with the selected side of the topmost document sheet in said stack for ready viewing by an operator. Document sheets are selectively fed from the stack seriatim in a first mode of operation along a first feed path from and back to the support in a closed-loop that inverts a sheet and directs the sheet into association with the reproducing station selected side down and then inverts the sheet again and directs the sheet to the top of the stack selected side up, or in a second mode of operation along the first feed path from the support through the reproduction apparatus station and back to the support through a second feed path prior to association with the reproducing station for inversion thereof and through a third feed path subsequent to association with the reproducing station for inversion thereof, whereby in each of the feed modes the selected side of each sheet always faces up when in the stack.
