Abstract

A recirculating automatic document feeder includes a follower finger which follows the separation between document sheets awaiting copying and document sheets already copied and returned to the document feeder stack. Fig. 1 shows a copier having a recirculating automatic document feeder 10. This feeder contains a duplex original document stack 11 which comprises N different images carried by N/2 sheets. The document feeder operates to feed sheets from the top of stack 11, one at a time, through path A, to platen 12 for copying. The document is then inverted, by way of path C, the other side is copied, the document is again inverted, and the document is restacked on the bottom of stack 11 by way of path B.
