PURPOSE:To easily adjust the quantity of light according to the sensitivity of a photosensitive material and to obtain a proper copy image by providing a light quantity adjusting member on the optical system path from an original to the photosensitive material when the photosensitive material is exposed to the image by a scanning system. CONSTITUTION:The silver halide color photographic sensitive material 1 is drawn out of a dark box 2, cut by a cutter 7 to specific length, and conveyed by a belt 10. Further, the original is placed on an original platen 15 and scanned for exposure by a light source 16, and reflected light from the original is reflected by mirrors 18, 19, and 20 and adjusted in quantity through a light quantity adjusting member 21 and a lens 22. Then the conveyed photosensitive material is exposed to the reflected light whose quantity is adjusted between rollers 13 and 14 through mirrors 23 and 24. Further, the light quantity adjusting member 21 consists of plural achromatic filters which differ in density and a proper filter is selected according to the sensitivity of the photosensitive material. Thus, a filter with different density is selected according to the sensitivity of the photosensitive material, so the quantity of light is easily corrected. |
