ABSTRACT:
A paper feeding apparatus is provided with a paper feeding roller and a paper separating plate mounted on an end of a spring-biased swingable lever. Paper sheets are separated, one sheet from the other, at a gap between the paper feeding roller and the paper separating plate. A guiding means is provided in opposition to a swingable part of the lever, and a stopper is interposed in a space between the swingable part of the lever and the guiding means. The stopper is movably biased into mechanical engagement with the swingable part of the lever, thereby to prevent double-feed of paper sheets by maintaining a predetermined extent of the gap between the paper feeding roller and the paper separating plate.
