ABSTRACT:
An automatic original feeding device includes a pick-up mechanism for picking up originals placed on a holding portion, a feed roller for feeding the picked-up original onto an original table of an image forming apparatus and delivering the fed original from the original table, and a discharge mechanism for discharging the delivered original to a discharge portion. The feed roller is arranged to be movable between a contact position where the feed roller is in contact with the original table so that the original can be delivered onto or from the original table, and an off position where the feed roller is separated from the original table. The feed roller is moved to the off position by a moving mechanism at the start of operation of the discharge mechanism.
