Illumination device for copying apparatus and the like

摘要

An illumination device for use in copying apparatus and the like for illuminating an original, the device having an elongated light source and reflecting members each of which is disposed at each side of the optical path from the original to a transmission system for transmitting the image light. The reflecting members reflect the light from the elongated light source toward the vicinity of opposite end portions of the illumination area in the longitudinal direction of the source. The device gives a uniform illumination intensity distribution and achieves a high illumination efficiency with a simple construction.
