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 3):
The sheet feeding apparatus according to  claim 1 , wherein the restriction member is pivotable about a first axis extending parallel to the rotation axis in a position below a portion of the support surface, the restriction member being configured to, when the stopper moves to the second position, separate from the stopper and retreat below the portion of the support surface.
