型電子写真複写機の照明装置。[Claims for Utility Model Registration] (1) A slit exposure type electrophotographic copying machine using illumination means in which a plurality of light-emitting lamps are arranged along the longitudinal emission center of one reflector through an opening in the reflector. In the illumination device, the leading edge reflective portion of the opening is moved to a position where the light from the illumination means reflected by the reflector plate is blocked by the luminescent lamp bulb and does not affect the luminous flux distribution reaching the document irradiation surface. A lighting device for a slit exposure type electrophotographic copying machine, characterized in that it is located at the front. (2) Claim 1 of the utility model registration, characterized in that the front edge of the opening of the reflector through which the light emitting lamp passes is expanded to a position where the light reflected by the reflector is not blocked by the light emitting lamp bulb. An illumination device for the slit exposure type electrophotographic copying machine described above. (3) Utility model registration claim 1, characterized in that the inner surface of the reflector up to a position where the light reflected by the reflector is not blocked by the light-emitting lamp bulb is painted black or has a diffused surface. Lighting system for slit exposure type electrophotographic copying machine.
