Abstract: A document handling system particularly suitable for electronic imaging by sequentially feeding uppermost document sheets (18) stacked in an input tray (20) to be imaged in forward serial order at an imaging station (16) and restacked collated in an output tray (22), with a short and compact "U" shaped common document feeding path also providing the majority of a duplex document feeding path (24) for returning duplex document sheets imaged on their first sides back to the imaging station for imaging their second sides. The input and output trays are in a space saving closely superposed relationship defining a protective confining inverter chute space therebetween within which the duplex document sheets may be fed out over the output tray by a dual mode reversible output sheet feeder at the "U" shaped path output and then reversed to feed back through a short linear duplex document feeding path into the entrance of the same "U" shaped document sheet feeding path for simplex document sheets to provide a duplex loop path.

Abstract: A document reproduction system with a first large imaging platen (12a) on which documents are scanned by moving an imaging system thereunder, and an automatic document feeding system (ADF) for sequentially feeding documents to a directly adjacent smaller second (removable) imaging platen (12b) where the same imaging system may be stationarily positioned. A recess is provided between the opposing edges of the first and second platens extending substantially below their upper surface. The ADF has a document lead edge member extendable down into this recess to positively catch and deflect documents away from the upper surface of the second platen after the documents have been moved over this surface and imaged. The first and second platens are abutting at their lower surfaces, below the notch, to define a contiguous lower surface. The recess may be formed by an inclined beveled end (5b) of the first platen. The imaging station is preferably not centrally of the second platen, and the second platen reversible, to change the position of the imaging station thereon. The first and second imaging platens have coplanar upper and lower surfaces and are comonly mounted. The ADF has two trays which overlie the first platen and one another.
