ABSTRACT:
A sheet feeding device includes a pick roller and a resilient element disposed above the pick roller. The pick roller has a roller surface. The resilient element includes two side resilient arms and a center resilient arm located between the two side resilient arms. Free ends of the two side resilient arms are pushed forward by all sheets when the sheets arrive between the free ends of the two side resilient arms and the roller surface. A free end of the center resilient arm faces the roller surface of the pick roller and maintains a gap therebetween. When too many pieces of paper are drawn forward to the resilient element, the side resilient arms are pushed forward further more, the uppermost paper contacts the center resilient arm. The center resilient arm cooperates with the side resilient arms to provide the paper a pressure big enough to be conveyed forward.
