Abstract
An image exposure apparatus in which positioning of a photosensitive material, such as a printing plate to be wound around a rotating drum, is implemented in a small space. A turning unit and a transport conveyor are provided at a plate supply/transport section. The turning unit trains the printing plate about the rotating drum and feeds the plate to the transport conveyor. At the transport conveyor, the printing plate is transported and a leading end of the printing plate abuts pin rollers. Then, a positioning motor is operated to move the turning unit and the transport conveyor integrally. Thus, the printing plate abuts another pin roller in a width direction to implement positioning of the printing plate. The leading end of the positioned printing plate is then fed to a puncher by the transport conveyor.
Claims17
An image exposure apparatus for enabling positioning of a sheet-like photosensitive material at a rotating drum by positioning the photosensitive material at a predetermined position before the photosensitive material is wound onto a peripheral surface of the rotating drum in order to be scanningly exposed, the image exposure apparatus comprising:
- a transport device which imparts transport force to each of two end portions in a width direction of the photosensitive material, which width direction is perpendicular to a transport direction of the photosensitive material, and transports the photosensitive material while maintaining the photosensitive material in a state in which the photosensitive material is tilted at a predetermined inclination;
- a first positioning device which stops each of two end portions in the width direction of a leading end of the photosensitive material, which is transported by the transport device, at a predetermined position;
- a moving device which moves the transport device and the photosensitive material integrally along the width direction of the photosensitive material after the photosensitive material has been stopped at the predetermined position by the first positioning device;
- and
- a second positioning device which stops the photosensitive material, which is moved by the moving device, at a predetermined position.
