ABSTRACT:
A paper feeding device used for feeding stacked paper to an electrophotographic copying machine is provided with a lift for a stack of papers, which move the top sheet against a swingably supported feeding roller as the size of the stack decreases under use. Forwardly of the feeding roller in the direction of travel of the paper is a plate in frictional contact with the roller, the paper being thus fed forwardly to the copying machine through the nip between the roller and plate. This arrangement avoids the problem of a multifeed of the sheets. The feeding-out operation may be further improved by the provision of separating claws engaging the leading corners of the paper as it passes from the feeding roller. Raising of the lift is controlled by a detecting device actuated by position of the swingable support for the feeding roller.
