Patent ID: 8393610

Claim:
A sheet feeding device configured to feed stacked sheets one by one in a sheet feed direction, comprising: a sheet tray configured to accommodate the stacked sheets; a feed-out roller protruded from the sheet tray and configured to feed the stacked sheets from the sheet tray; a feed-out nip member arranged above and opposite to the feed-out roller, the feed-out nip member being configured to contact an uppermost sheet of the stacked sheets and bias the stacked sheets toward the feed-out roller; a separation unit located on a downstream side, in the sheet feed direction, of the feed-out roller, the separation unit being configured to separate a lowermost sheet from the stacked sheets fed by the feed-out roller; a friction member configured to apply friction to the uppermost sheet of the stacked sheets at a position different from a position where the feed-out nip member contacts the uppermost sheet; and an interlocking mechanism configured to interlock the friction member and the feed-out nip member such that movement of the feed-out nip member toward the feed-out roller causes movement of the friction member away from the sheet tray and movement of the feed-out nip member away from the feed-out roller causes movement of the friction member toward the sheet tray.
