Abstract: A reciprocating document handler for transporting documents comprising a belt transport supported for transporting sheets in a first and a second, opposite direction. The device further includes apparatus for allowing documents moving in the first and second directions, respectively, at an exchange area on the belt to slide over one another substantially freely. The device includes a pressure member to urge the belt into engaging with transported documents and a mechanism for reducing the bearing of a pressure member proximate the exchange area to promote the substantially free sliding engagement of the documents transported in opposite directions.

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.

Abstract: A bi-directionally vertically bin indexed multi-bin sheet sorter, for a fixed position sheet output, such as a copier or printer, with a sheet edge alignment registration jogging system for tamping sheets which are in the immediately previously loaded bins directly above or below the bin being loaded (the bin adjacent the fixed sheet output) concurrently with that bin being loaded but without interfering with the feeding of the sheet into that bin. A single jogging system is stationarily mounted adjacent the sheet output to intermittently horizontally move a jogging member (which extends vertically alongside all three of these adjacent sorter bins) into the above and below bins for tamping sheets therein towards a registration position, such as a corner stapling position, but is configured to not extend into the sheet feeding path and to not tamp sheets in the bin being loaded.
