ABSTRACT:
A sheet feeder includes a support plate inclined backward and a feed roller for feeding one by one the sheets of paper stacked on the plate. A first support surface and a second support surface are formed at or near the bottom of the plate to support the front ends of the sheets. The second surface is lower in frictional resistance than the first surface. The second surface can be moved by an operating lever between a first position, where it is protruded from the first surface toward the sheets, and a second position, where it is retracted from the first surface away from the sheets. If the sheets are relatively rigid, their front ends are supported by the second surface in the first position, and they can therefore be fed smoothly.
