ABSTRACT:
In a sheet feeding apparatus, a member, supporting at one end thereof a rotatable pressure roller, is mounted turnably at the other end thereof on an input shaft driven by a motor. This member is coupled to the input shaft via a friction generating mechanism which generates a friction force. This friction force allows the rotatable pressure roller to be pressed with an optimum pressure onto a sheet to be fed.
