成したことを特徴とする複写機の照明装置。 Light emitted from a long tube-shaped light bulb, which has a plurality of light emitting parts spaced apart in the direction of the tube axis, is reflected by a gutter-shaped reflector that accommodates the tube-shaped light bulbs. In an illumination device for a copying machine, the light is reflected by a copy original placed on the translucent mounting plate and formed into an image on a photoreceptor drum through an optical system such as a lens. A low reflection part having a lower reflectance than other parts is formed at a position facing each of the light emitting parts, and these low reflection parts are formed so that the reflectance increases as the distance from the light emitting part increases. A unique lighting system for copiers.
