Abstract
A document handling apparatus for a duplicating machine or copier is disclosed and includes a document supply tray, a turnaround roller and the exposure platen arranged in a general horizontal configuration wherein all operating areas and separate transports are available for operator observation and jam clearances. The turnaround roller permits return of document sheets to the platen in an inverted orientation to permit copying of duplex document sheets. The rotational speed for this operation may be significantly increased relative to the processing speed of the copier and the normal feeding speeds of the document sheets from the supply tray to the platen in order to maximize throughput of the copier. For normal return of the document sheets for the platen area, the rotational speed of the roller may be relatively high compared to the document feeding speed, thereby minimizing time losses due to machine pitch spacings between document sheet changes.
