ABSTRACT:
A recirculating document feeder for a copier/duplicator removes sheets seriatim from the bottom of a stack of sheets, circulates a removed sheet to a position for copying, and then returns the sheet back onto the top of the stack of sheets. A sheet separator engages the sheet that initially is on top of the stack for separating the sheets in the stack that have been circulated along the path from those sheets in the stack that have not been circulated along the path. In response to feeding of the top sheet of the stack along the path, the separator is retracted and then returned to the top of the stack after the top sheet has been circulated for copying. The separator is driven along a generally rectilinear path and guided along that path by a pin in the separator that travels along a slot formed partially in each of two facing surfaces.
