PURPOSE:To enable both of the images of general documents, etc., and the images of a cathode ray tube to be copied by switching an original illumination lamp and the starting circuit of the cathod ray tube over to each other in linkage with displacement of a reflection mirror. CONSTITUTION:A photosensitive film 1 made of an org. photoconductor is fixed to a slide frame 3, and a processing table moves below the film 1 to electrostatically charge and expose the film 1. The image of the cathode ray tube 10 is changed in the direction with a reflection mirror 12 and projected through a projection lens 13 on the film 1 to form a latent image. When a mirror box 11 is slid to withdraw the mirror 12 from the light path, the starting circuit of the tube 10 is inactivated to actuate a switch 76 for turning on an original illuminating lamp, thus exposing the film 1 to the optical image of an orignal 14. |
