Abstract

A paper feeding apparatus includes a housing accommodating a plurality of papers, a pickup unit, a rotation transmitting member and a torque transmitting member. The pickup unit has a pickup lever, a driving shaft rotatably supporting the pickup lever, and a pickup roller rotatably provided on an end of the pickup lever. The rotation transmitting member transmits a rotating force of the driving shaft to the pickup roller. The torque transmitting member is provided between the driving shaft and the pickup lever. The torque transmitting member selectively rotates one of the pickup lever or the pickup roller depending on a torque acting on the driving shaft. The pickup roller is rotated while being pressed against the papers, thereby feeding the papers one by one out of the housing.
