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: An apparatus (48) which advances a sheet (25) through a transfer zone (64) and into registration with information developed on a moving member (20). The sheet (25) is advanced to a position wherein a leading portion thereof is within the transfer zone (64) and a trailing portion thereof is immediately behind the transfer zone (64) relative to the forward direction of movement of the moving member (20). The leading portion of the sheet (25) is advanced through the transfer zone (64) at a first velocity and the trailing portion of the sheet (25) is advanced in a region immediately behind the transfer zone (64) at a second velocity, which is greater than the first velocity, so as to create a buckle (19) in the trailing portion of the sheet (25) in the region. The buckle (19) functions to eliminate relative velocity between the photoconductive belt (20) and any portion of sheet (25) within the transfer zone (64) so as to substantially eliminate slip between the sheet (25) and the photoconductive belt (20).

Abstract: A bottom vacuum corrugated feeder (BVCF) includes a tray for supporting a stack of documents. The tray is angled downhill relative to the feeding direction of the documents such that the leading edge of the stack is urged to a common stop member. The tray also includes a single side guide for aligning one side edge of the stack. A stack height sensor sends a signal corresponding to stack height to a controller which in turn controls voltage to be applied to a DC motor controlled blower based on a predetermined ratio of air flow pressure to stack pressure. The structure enables intermixed size document feeding in a BVCF.
