ABSTRACT:
A sheet supply apparatus is provided having a pressure plate for supporting sheets on a sheet supporting surface, a pick-up roller for feeding out the sheets supported by the pressure plate, a plate member for separating the sheets fed out by the pick-up roller one by one, and a separation pad provided on the sheet supporting surface of the pressure plate opposite the pick-up roller. The separation pad protrudes from the sheet supporting surface toward the sheets to contact frictionally the lower surface of the bottom-most sheet supported by the pressure plate. The separation pad has an upper surface which is higher at a portion opposing the pick-up roller than a portion downstream thereof, in a sheet feeding direction, relative to the sheet supporting surface of the pressure plate, to urge an end of a sheet fed out by the pick-up roller toward the pressure plate.
