Abstract
A sheet feeding apparatus, comprising a pad base, a groove along the central line of the pad base, and a spring embedded in the groove, is disclosed. The top of the spring protrudes above the top surface of base and a series of inclined protrusions are formed at two sides of the groove. The sheets are driven by rollers and rise gradually along the protrusions such that the sheets are separated one-by-one. Moreover, a radial arrangement of the ribs and the sheet-separating pad allows the lower edge of each sheet to move smoothly so that paper jams can be prevented.
