Abstract

PURPOSE:To obtain two light sources for image exposure and heat development with use of a lamp, by dividing the light through a mirror that reflects the ultraviolet rays and transmits the infrared rays, respectively. CONSTITUTION:Only the components of <=450nm wavelength of the light of a flash lamp 6 are reflected by a mirror 5. The image of a transparent original drawing 4 is projected on the heat development type diazo photosensitive paper 3, and a latent image 2a is formed to a photosensitive layer 2. The drawing 4 is torn off and only the paper 3 is carried onto the upper surface of a mirror 7 by a roller, etc. The components of >=450nm wavelength of the light of the lamp 6 pass through the mirror 7 and reaches the layer 2 to give heat development to the image 2a.
