US 5,984,298 A · Sheet feeding apparatus with a driving device for a paper stopper

Abstract

A sheet feeding apparatus having a feeding roller for feeding a sheet, a support shaft forwardly and reversely rotatable integrally with the feeding roller and a stopper disposed upstream of the feeding roller in the sheet feeding direction for temporarily regulating the feed of a sheet to the feeding roller. When the rotation in one direction of the feeding roller is transmitted to a locking member through a one-way clutch, the locking member is rotated to lock the stopper. When the feeding roller is rotated in the opposite direction, the locked state of the stopper is released.
