Abstract

A paper feed device comprises support frames 21, 22 disposed parallel to each other, and a rotation shaft 29 journaled in the support frames and upon which feed rollers 28 are fitted. The feed rollers 28 are imparted with vibrations in a direction perpendicular to the paper feed direction. Thus single sheets of paper may be fed from a pile by the rotation of the vibrating paper feed rollers 28 located thereabove. <IMAGE>
