ABSTRACT:
A sheet feeding apparatus for a printing device includes a pickup roller and a feeding roller picking up sheets loaded on a tray and feeding the sheets into a sheet feeding path, respectively, a rotation member installed on a rotation shaft of the feeding roller to support and rotate the pickup roller at a free end, a relay gear engaging the feeding roller and the pickup roller, a clutch unit selectively transferring a raising force of the rotation shaft to the rotation member, and a stopper installed in the rotation member to be elevated and lowered with respect to the rotation member to block a path between the pickup roller and the feeding roller. Accordingly, since the pickup roller is raised to allow the sheets to be loaded and then lowered after the sheets are loaded on the tray, front ends of the sheets are automatically inserted under the pickup roller. In addition, since the stopper aligns the sheets under the pickup roller when the sheets are pushed toward the feeding roller, the front ends of the sheets are prevented from being crumpled by the feeding roller.
