Abstract
A paper feeding device for taking out paper sheets contained in a paper containing section one at a time by a paper feeding roller to feed the paper sheets. When a paper jam occurs in the position of the paper feeding roller, the rotation in one direction of the paper feeding roller is continued, so that the paper feeding roller is returned to its home position. At the time when the paper feeding roller is returned to its home position, the rotation of the paper feeding roller is stopped, to prepare for paper jam processing. A nip portion which nips the paper sheet and a non-nip portion spaced apart from the paper sheet are located on an outer peripheral surface of the paper feeding roller. In the home position, the nip portion is not opposed to the paper sheet and the non-nip portion is opposed to the paper sheet. That is, when a paper jam occurs, the paper feeding roller is stopped in a state where it is not pressed against the paper sheet in the paper containing section.
