Patent ID: 7497432

Claim:
A sheet supplying device for supplying sheets one by one, comprising: a separation roller having an outer circumferential surface contacting at least a part of the sheets in a stacked state; a pad located to face the outer circumferential surface of the separation roller; a holder that holds the pad and is movable relative to the separation roller; and a pressing mechanism that presses the holder in a direction in which the pad held by the holder approaches the separation roller, wherein the pad contacts a first surface of a sheet being fed by rotation of the separation roller, and the first surface of the sheet is opposite to a second surface of the sheet contacting the outer circumferential surface of the separation roller, wherein the holder has a recessed portion formed on an upstream side of a pressurization point at which the sheet being fed is nipped between the separation roller and the pad, space being formed by the recessed portion and a surface of the pad facing the holder, wherein the holder has a holding portion that holds the pad and is located downstream with respect to the pressurization point, and wherein the holder is configured to be rotatable about a rotational axis situated on a downstream side of the pressurization point so that the holder is rotated to move near to or to move away from the separation roller.
