Abstract: An opening is formed in the bottom portion of a paper cassette, and a rockable elevator is opposed to the opening. The elevator is rocked by an elevator operating mechanism, thereby pushing up a tray so that paper sheets in the paper cassette reach a position suited for takeout, or getting out of the cassette. The elevator is continuously moved up and down a plurality of times by means of the elevator operating mechanism after the end of paper feeding operation, whereby the takeout end portions of a second one of the paper sheets P and its subsequent ones, which project from the paper cassette as the sheets are taken out by a takeout mechanism, are vertically oscillated so that those sheets are repeatedly curved and straightened. As a result, the paper sheets projecting from the paper cassette are automatically returned to the cassette by their own elasticity.
