Abstract
A paper feed apparatus of the present invention includes a pick mechanism for successively taking out, by use of a pick roller, a plurality of sheets of paper stacked on a chute from the bottom side thereof, leading ends of the sheets being aligned by means of a stopper blockin a state in which the sheets are stacked on the chute. Moreover, the apparatus includes a roller guideand an abutment guide. When the roller guideis raised to a paper setting position in a direction away from the pick roller, the roller guideraises the leading ends of the sheets stacked on the chute to thereby prevent contact between the sheets and the pick roller. The abutment guidealigns the leading ends of the sheets when the roller guideis raised. When a pick operation is started, prior to retraction of the roller guide, sheet pressing operation of a pick armand retraction of the abutment guideare performed, and then the sheets are taken out through a clearance formed between the distal end of the stopper blockand the pick roller
