ていることを特徴とする複写機の照明装置。 A tube-shaped light bulb was placed inside a gutter-shaped reflector body with an opening on one side, and the light emitted from the tube-shaped bulb was reflected by the reflector body and placed on a translucent mounting plate. In addition to converging the light onto the copy document, a light control plate is provided at the upper end of the reflector body, and the amount of protrusion can be adjusted in the direction of the optical path of the light reflected by the reflector body. In an illumination device for a copying machine, each divided light control plate is independently directed toward the optical path of the reflected light, and the amount of protrusion can be adjusted. An illumination device for a copying machine, characterized in that the light plate has a notch at its end and a protrusion formed near the center.
