ABSTRACT:
The feed device includes: a feed tray for stacking a multiple number of sheets thereon; a feed roller for feeding sheets from the feed tray; and a frictional plate which is pivotally supported on a pivotal axle and urged by a pressure spring in order to prevent multiple delivery of sheets from being caused by feed roller. The pivotal axle of the frictional plate is disposed on the downstream side, with respect to the sheet feeding direction, of the pressure nip between the feed roller and frictional plate, and on the feed roller side with respect to the tangent line of the frictional plate to the feed roller.
