ABSTRACT:
A sheet feeding apparatus of the type capable of feeding sheets individually from the lowermost sheet of a stack of sheets placed on a sheet tray, for use in facsimile apparatus, a copying machine or the like, comprises a sheet feed roller rotated in the sheet feeding direction and a sheet separation roller also rotated in the sheet feeding direction and disposed downstream of a sheet feed roller in terms of the sheet feeding direction. A brake member is in contact with the peripheral surface of the sheet separation roller and a pressure application plate is disposed above the sheet feed roller to bring the sheets into pressure contact with the sheet feed roller. The pressure application plate is movable between its pressure application position and a position substantially away from the sheets whereby the pressure plate may be held away from the sheets when they are being driven by the sheet separation rollers. Stopper members for causing the leading edges of the sheets to collide therewith are disposed in a sheet feed path between the brake member and sheet feed roller and the stopper member allow a limited number of sheets to pass towards the brake member. The stopper member is movable to a position where it is away from the sheet separation roller for removing jammed sheets.
