Disclosed is a recirculating document handling unit 1 for automatically placing documents to be copied on the platen 2 of a conventional xerographic or other copier. It includes a document inverter 3 for inverting duplex documents so that their opposite sides may be copied. The documents to be copied are fed individually from the bottom af a stack 4 by a bottom feeder 5 closely adjacent the platen 2. Each document is fed onto the platen by an input roller pair 6a and 6b, which may be directly driven by engagement of the roller 6a by a large roller 7 driven in the direction shown. The registration of the document may be accomplished on the platen by various known systems, such as the illustrated registration belt 8 and raised registration edge 9. Reversal of the registration belt 8 after copying drives the document back toward the nip between the roller pair 6a and the roller 7, which transports the document into a diverter gate 10.
