ABSTRACT:
An improved sheet paper feed apparatus for a printing apparatus having a platen for holding and providing at least longitudinal motion to a sheet of paper. The sheet feed apparatus comprises a rectangular tray including a rear paper support portion and a spaced apart forward paper support portion, the portions for supporting thereon the opposite ends of a stack of paper. A shingler wheel is positioned intermediate the support portions for engaging the lowermost sheet of the paper sheet stack, and the shingler wheel is rotated in a first direction to move the lowermost sheet of the stack away from the forward support portion until the lowermost sheet is no longer supported thereby, and then in the opposite direction to drive the lowermost sheet beneath the forward paper support portion, the forward paper support portion comprising in the preferred embodiment a pair of inwardly projecting, spaced apart fingers. The improvement includes a cover member mounted for rotation on the tray and dimensioned to fit within the tray superimposed of the stack of papers. A paper stack lift is mounted adjacent the fingers and moves between a first recessed position below the plane of the fingers and a second position above the plane of the fingers. The cover means is coupled to the stack lift so that upon rotation of the cover member away from the stack, the stack lift assumes the second position and when the cover is in place superimposed of the stack, the lift is in the first position.
