Abstract:
A sheet feeding apparatus includes a support member having a support surface, a feed roller rotatable about a rotation axis located below a portion of the support surface, a separation roller disposed downstream from the feed roller, a separator disposed upstream from the separation roller, a stopper, when viewed in a direction of the rotation axis, disposed at least partially overlapping the separator and movable between a first position in which the stopper crosses the support surface and restricts leading edges of the sheets supported on the support surface and a second position, downstream from the first position in a conveying direction, in which the stopper is spaced apart from the support surface, and a restriction member configured to hold the stopper in the first position and to restrict movement of the stopper while continuing to support the stopper moving from the first position to the second position.

Claim (Index 1):
A sheet feeding apparatus comprising:\n a support member having a support surface configured to support stacked sheets; a feed roller rotatable about a rotation axis located below a portion of the support surface, the feed roller having an outer peripheral surface, at least a portion of the outer peripheral surface protruding through the support surface, the feed roller being configured to feed the sheets supported on the support surface downstream in a conveying direction; a separation roller disposed downstream from the feed roller in the conveying direction, the separation roller being configured to separate a single sheet from the sheets fed by the feed roller and convey the sheet downstream in the conveying direction; a separator disposed upstream from the separation roller in the conveying direction, the separator having an upper end and a lower end, the lower end being located downstream from the upper end in the conveying direction; a stopper, when viewed in a direction of the rotation axis, disposed at least partially overlapping the separator, the stopper being movable between a first position in which the stopper crosses the support surface and restricts leading edges of the sheets supported on the support surface and a second position, downstream from the first position in the conveying direction, in which the stopper is spaced apart from the support surface; and a restriction member configured to hold the stopper in the first position and to restrict movement of the stopper while continuing to support the stopper moving from the first position to the second position.
