ABSTRACT:
This paper feeding mechanism comprises a first spring for biasing a stack of paper against a belt for driving one or two sheets of paper from the stack toward a gap which is slightly larger than the width of one sheet of paper, and a second spring for flattening the selected sheet or sheets against the belt just prior to entering the gap. The belt is held solidly in position by a backing Teflon block to form one side of the gap, and a sharp edge that is positionally adjustable forms the other side. The sharp edge is rounded slightly to compensate for the possibility of mechanical inaccuracies, and the second spring presses the paper against the belt just prior to the knife edge for more reliable operation with stiff paper.
