ABSTRACT:
Document sheets are removed seriatim from the bottom of a stack of sheets by an oscillating vacuum feeder having a plurality of spaced tube sections. The feeder delivers a removed sheet to a sheet transport mechanism, which transports it to the platen for copying and then removes the sheet from the platen. The sheet transport mechanism has at least one vacuum belt that passes between two adjacent sections of the feeder and picks up a sheet as it leaves the feeder so that the sheet is tacked to the feeder or the vacuum belt throughout its path of travel from the stack of sheets to the platen. After the sheet is removed from the platen it is returned to the stack of sheets on top of other sheets in the stack. A sheet inverter can be provided for inverting duplex document sheets so that both sides of such sheets can be copied. Sheets also can be fed to the platen along a non-recirculating path by a document positioner apparatus. Sheets fed by the document positioner also are advanced across the platen by the vacuum belt.
