Abstract
PURPOSE:To effectively radiate a light beam from an exposure source on both surfaces of a photosensitive sheet and to shorten an exposing time by reflecting the light beam transmitted through the photosensitive sheet from the exposure source by a surface mirror and radiating it on the photosensitive sheet. CONSTITUTION:The photosensitive sheet 1 is arranged so that it abuts on the surface mirror 8 and an image which should be exposed is displayed with a cathode-ray tube 5. The image light l of the displayed image is radiated on a microcapsule layer 2 on a photosensitive sheet base 1a through a lens 6 and a color filter 7 so as to execute the exposure. The transmitted light is reflected on a reflecting part 8a and is made incident on the photosensitive sheet base 1a again. The image light is radiated on the microcapsule layer 2 from the opposite side to a direct irradiation from the cathode-ray tube 5 so as to execute the exposure. The microcapsule layer 2 is exposed with the image light which directly reaches from the cathode-ray tube 5 and it is radiated to be exposed with the image light which reaches by reflecting by the surface mirror 8 from both surfaces. If the luminance of the cathode-ray tube is same, the light quan tity which is nearly twice as much as in the case where there is no surface mirror can be radiated and the exposing time can be shortened.
