ABSTRACT:
A double-feed prevention device in paper feeding apparatus is provided with a paper feeding roller and a frictional member carried on a paper separating plate mounted on an end of a spring-biased swingable lever. Paper sheets are separated one by one at a gap having a predetermined dimension between the paper feeding roller and the frictional member. A part of the swingable lever is always engaged by a locking member so as to prevent separation of said frictional member from said paper feeding roller by wear off in a surface of said paper feeding roller. The double-feed prevention device according to the present invention is further provided with releasing means for disengaging between the locking member and the swingable lever to remove jammed paper from the gap as desired.
