Abstract:
1. A sheet feeding device comprising: a sheet storing portion having a stacking surface and in which sheets are stacked on the stacking surface; a feeding roller that rotates to feed each of the sheets in the sheet storing portion while being in contact with a topmost one of the sheets; a support member having a support surface that is different from the stacking surface of the sheet storing portion and that supports downstream-side part, in a sheet feeding direction in which the feeding roller feeds the sheet, of the sheets in the sheet storing portion from below a bottommost one of the sheets the support member being movable in a substantially perpendicular direction with respect to the stacking surface such that the support surface comes into contact with and moves away from the feeding roller in the substantially perpendicular direction, the support member moving in the substantially perpendicular direction at the time of sheet feeding in such a manner as to lift the downstream-side part of the sheets in the sheet storing portion to contact with the feeding roller; and a stopper member that is out of contact with the support member while being in contact with the feeding roller, the stopper member being configured to come into contact with leading ends of some sheets to be fed by the feeding roller and to stop sheets other than the topmost sheet from being fed, wherein the support surface of the support member forms a sloping surface that slopes upward, with respect to the stacking surface, toward a downstream side in the sheet feeding direction, wherein a sloping angle of the sloping surface with respect to the stacking surface is invariable while the support member is moved in the substantially perpendicular direction.
