ABSTRACT:
A drive mechanism is provided for the separator member of a recirculating document feeder. The separator member distinguishes pages of a document yet to be fed to a copier from those already fed to the copier by the recirculating document feeder and returned to the document stack during the document copying cycle. The drive mechanism includes a rotatable member mounted for coaxial rotation with the rotatably mounted separator member. A plurality of pawls on the rotatable member are mounted for movement between a first position in which the pawls are disposed to drivingly engage the separator member to rotate the separator member and a second position in which the pawls are disengaged from the separator member. When the rotatable member is driven, one of the pawls is moved to its first and second position in timed relation to the feeding of the last page of a document to be copied from and to the document stack respectively.
