ABSTRACT:
A paper feeding device includes a pick roller, a spring element and a separator pad. The pick roller has a roller surface. The spring element is disposed above the pick roller. The spring element has two spring arms extending toward two ends of the pick roller. Free ends of the two spring arms extend to positions outside the two ends of the pick roller and below the roller surface so as to be contactless with the roller surface and are pushed forward and upward by papers and then transfer a press force to the pick roller. A separator pad is arranged in front of the spring element and contacts with the roller surface of the pick roller for cooperating with the pick roller to separate a lowermost one of the papers. Because the spring arms are contactless with the pick roller directly, so the spring arms do not rub the pick roller, which avoids the pick roller being abraded.
