摘要 |
An illumination means for an electrographic reproduction machine in which a single light source is used in combination with a primary and a secondary elliptical reflector to furnish direct and reflected light as a narrow band of illumination and in which a third flat reflector is used to reflect a portion of the light from the light source which would not otherwise be directed in such a narrow band back into the primary and secondary reflectors to be reflected into the narrow band and to balance the direct and reflected light. |
