ABSTRACT:
A sheet feeding and registering apparatus includes a document platen, a single wide document transport belt and a sheet registration member. The sheet registration member is a linear member with a plurality of lower registration edges at a first level above the platen and a plurality of sheet stripping portions raised to a level above the first level and forming therewith a series of undulations. The raised sheet stripping portions are inclined to a direction opposite the direction of sheet transport and with the document platen form a small sheet corner capturing cavity. When feeding a slightly skewed sheet to the registration edge the lead corner is first stripped from the transport belt, then physically captured by the cavity and pivoted about its lead edge until it is fully registered against the registration member.
