ABSTRACT:
A sheet feeding apparatus for sequentially moving sheets into a predetermined registration position with a sheet support surface of an associated optical imaging device including a sheet displacement assembly for engaging and guidingly displacing the sheet along a predetermined displacement path having an upstream end and a downstream end; an abutment surface disposed along the displacement path in spaced relationship from the sheet support surface; and a drive for driving the displacement assembly for moving the sheet downstream a predetermined distance along the path past the abutment surface, then moving the sheet upstream into edge aligning engagement with the abutment surface and then moving the sheet downstream a predetermined distance along the path.
