Abstract
A sheet feeder for a laser printer or similar image recording apparatus which is selectively operable in an automatic sheet feed mode and a manual sheet feed mode includes a manual feed guide plate which is located above a feed tray or a cassette. A presser member is mounted on the guide plate to be movable between an operative position where its front end portion intervenes between a feed roller and a friction pad and an inoperative position where it does not do so. When the presser member is moved toward the feed roller until its front end portion intervenes between the feed roller and the friction pad, the friction pad is physically separated from the feed roller and, instead, the front end portion of the presser member is brought into pressing contact with the feed roller. In this condition, a paper sheet inserted by hand on and along the manual feed guide plate is pressed against the feed roller by the presser member and fed stably by the rotation of the feed roller.
