摘要: The present invention provides a symbol illumination apparatus configured to have a symbol such as characters printed on a front surface of a transparent member, and to allow light from a plurality of light sources to pass through an interior of the transparent member from one side of the transparent member, to illuminate the symbol. A lens sheet and a diffused sheet are inserted between the transparent member and the plurality of light sources in the symbol illumination apparatus. This configuration prevents a plurality of light rays from being seen on the bottom of the transparent member.
