Abstract

This automatic document feeder accepts a stack of original documents and operates to feed the document sheets, one at a time, to a copier's glass platen for copying. The feeder provides automatic document feeding with or without recirculation. The feeder also provides semiautomatic document feeding (SADF) with manual insertion of individual sheets to be copied. The following modes of operation are provided: (1) recirculation with simplex-to-simplex copying, (2) recirculation with simplex-to- duplex copying, (3) recirculation with either duplex-to-duplex or duplex-to-simplex copying, (4) non-recirculation with either simplex-to- simplex or simplex-to-duplex copying, and (5) manual feed of one sheet at a time with either simplex-to-simplex copying or simplex-to-duplex copying.
