項記載の複写機の照明装置。[Claims for Utility Model Registration] (1) Light emitted from a long tube-shaped light bulb in which a plurality of light-emitting parts are formed at intervals in the tube axis direction is transmitted to a gutter-shaped light bulb that houses the tube-shaped light bulb. A copying machine that directs light toward a translucent mounting plate using a reflecting mirror, reflects the light from a copy original placed on the translucent mounting plate, and forms an image on a photoreceptor drum through an optical system such as a lens. In the lighting device, the reflecting mirror is provided with a low reflection portion located on each optical axis connecting the optical system from each of the light emitting portions through the copy document and having a lower reflectance than other portions. Features: Copy machine lighting system. (2) Each of the above-mentioned low reflection parts is formed by forming a plurality of grooves in the direction of the tube axis of the tube-shaped light bulb in a direction perpendicular to the direction of the tube axis. The lighting device for a copying machine according to item 1. (3) The low reflection part is formed such that the reflectance approaches the other parts as it moves away from the light emitting part.
Illumination device for a copying machine as described in Section 1.
