Abstract

A document sheet advance apparatus for separating individual sheets from a stack of sheets characterized in that it includes a sheet feed tray tilted at an acute angle to the horizontal, a first fixed friction element having a front portion adapted such that a second friction element is located adjacent to the leading edge of said sheet stack, and is movable below said first friction element, said second friction element being below an edge front of the sheets located in said supply tray and adapted to grip a lower surface of the sheet located at the bottom of said stack and move it between it and said first friction element, a document retention surface having a lower portion adjacent said front portion of said first friction element and extending in a plane that is α inclined at an acute angle to said second friction element, said second friction element being supported by a first roller having its axis generally located in the plane of said document retention surface.
