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.

Abstract: A process for full-automatic and synchronous quick thermoprinting of stereoscopic color film and apparatus adopting the process uses the internationally accepted nontoxic oil ink to design patterns on a transfer medium, which medium is in turn absorbed by a special thin film so as to be attached to a printing stock, whereupon the thus prepared printing stock is put into the apparatus. By gas pressure a pressure column of an inclined surface is pushed downward so as to contact and press a sliding mold jig of the inclined surface to synchronously move toward the center, so that each outer mold thermocompresses onto the outer surface of the printing stock from upper, left, right, front and rear directions simultaneously. After a predetermined period at predetermined temperature, the mold automatically returns to its original position. The disadvantages of manual operation which is of lower efficiency and unstable quality are thus overcome.
