ABSTRACT:
A paper feeding apparatus is provided for use in an image forming apparatus. Such a paper feeding apparatus comprises a knock-up plate rotating upwardly and downwardly with a first end thereof provided as a hinge shaft, a driving motor and a paper feeding roller assembly to withdraw a single sheet of paper stacked on the knock-up plate by a driving a force from the driving motor, and further comprises a lift gear unit to upwardly rotate the knock-up plate by the driving force intermittently transmitted from the driving motor through a connecting means; a position sensor arranged to detect whether the sheets of paper stacked on the knock-up plate reaches a predetermined height proper to be fed to the paper feeding roller assembly; and a controller arranged to control the connecting means to be turned on and off based on a signal detected from the position sensor. As a result, a single driving motor is utilized to feed papers and drive a knock-up plate, thereby reducing production costs and enhancing internal space efficiency.
