Abstract:
A sheet feeding apparatus includes a support member having a support surface, a feed roller, a stopper, and a restriction member. The stopper includes a restriction surface configured to contact leading edges of sheets supported on the support surface. A tangent extends in parallel to the support surface and passes through a point on an outer peripheral surface of the feed roller, and the tangent and the restriction surface of the stopper crosses at an intersection point. When the stopper moves from a first position to a second position, the intersection point moves with a movement velocity in a direction parallel to the tangent, the movement velocity at the intersection point being defined as a specified movement velocity. The restriction member is configured to restrict movement of the stopper such that the specified movement velocity is greater than or equal to a circumferential velocity of the feed roller.

Claim (Index 5):
The sheet feeding apparatus according to  claim 3 , further comprises:\n a motor configured to rotate forward or backward to generate a drive force; a first transmission device configured to transmit the drive force of the motor to the feed roller, the first transmission device being configured to, when the motor rotates forward, rotate the feed roller in the conveying direction; a second transmission device configured to transmit the drive force of the motor to the restriction member; a one-way clutch disposed between the second transmission device and the restriction member, the one-way clutch being configured to, when the motor rotates forward, become disengaged, and to, when the motor rotates backward, become engaged; and an urging member configured to urge the restriction member in a direction to retreat the restriction member below the portion of the support surface, wherein the restriction member is configured to, when the motor rotates backward, hold the stopper in the first position against the urging member, and configured to, when the motor rotates forward, retreat below the portion of the support surface, the restriction member being configured to follow the second transmission device via the one-way clutch until the restriction member retreats below the portion of the support surface.
