Abstract
A photosensitive material is mounted onto an inner surface of a cylindrical inner surface drum. An input signal which provides the size of the photosensitive material is supplied to a controller. As the controller drives a pulse motor under the control of a control signal, a moving part with which punching units are connected is moved in a circumferential direction of the drum by means of the pulse motor and positioned at the desired positions for punching. Then only two punching units, determined by the controller in accordance with the size of the photosensitive material, are driven to punch holes in the photosensitive material.
