Patent ID: 7954807

Claim:
A sheet-feeding device for feeding a sheet in a predetermined sheet-feeding direction from a stack of sheets having a maximum height, the sheet-feeding device comprising: a sheet-feeding cassette including: a sheet holding surface for holding the stack of sheets; and a side wall extending upward from the sheet holding surface; a sheet-restricting plate provided in the sheet-feeding cassette at a position on a downstream side in the sheet-feeding direction for setting a position of the sheet in a sheet width direction which is perpendicular to the sheet-feeding direction; a cassette accommodating section for accommodating the sheet-feeding cassette drawably in a direction parallel to the sheet-feeding direction; and a projecting portion arranged on an upstream side in the sheet-feeding direction from the position where the sheet-restricting plate is arranged, the projecting portion being formed by partially projecting the side wall of the sheet-feeding cassette upward, a height of the projecting portion being higher than the maximum height of a sheet stack which can be accommodated in the sheet-feeding cassette, a height of parts of the side wall other than the projecting portion being lower than the maximum height of the sheet stack, the projecting portion being configured for preventing shifting of an upstream portion of the sheet in the sheet width direction.
