ABSTRACT:
A sheet feeding device for a business machine includes a cassette and a cassette receiving station which cooperate to move sheets in the cassette toward a sheet feed roll after the cassette has been fully inserted and which also cooperate to move sheets in the cassette away from the sheet feed roll immediately before the cassette is withdrawn. Two projections extend from opposite sidewalls of the cassette and cooperate with grooves in the receiving station for facilitating cassette insertion and removal and for locking the cassette in place. Sheets in the cassette rest on top of a pressure plate. A pressure arm in the receiving station moves in an opening in the bottom of the cassette below the pressure plate to move the latter, thereby raising or lowering the sheets. A lug formed on the cassette engages an operating arm for the pressure arm upon insertion of the cassette.
