照明装置。[Scope of claim for utility model registration] A lamp that emits illumination light through a glass tube,
It has a main reflector that reflects the illumination light and an auxiliary reflector that reflects the light from the main reflector, and directs a certain range of light reflected by the main reflector in a diagonal direction with respect to the document surface. After condensing light onto the illumination position of the original from the main reflector and reflecting a certain range of light from the auxiliary reflector, the original is illuminated from an oblique direction opposite to the oblique direction. A document illuminating device for a copying machine or the like that focuses light on an illumination position and illuminates the document, characterized in that a portion of the glass tube through which the light in the certain range passes is frosted.
