A paper feed stacker equipped with a pressure plate that opens when printing paper and presses the cut paper against the paper feed roller, a paper feed roller that feeds the cut paper set in this paper feed stacker toward the printer, and a paper feeder. In an automatic paper feeder equipped with a separation claw that separates cut paper sheets sent out by a roller one by one, an upper part is rotatably attached to a roller shaft supporting the paper feed roller, and a lower end thereof is attached to the roller shaft that supports the paper feed roller. A paper feed opening formed between the paper feed opening and the support surface in conjunction with the pusher plate is engaged with and closed by the support surface when paper is set, and is separated from the support surface when paper can be fed. An automatic paper feeder characterized by being provided with an opening/closing member that opens.
