Abstract:
A spread illuminating apparatus comprising: a bar-like light conductive member disposed along at least one end surface of a transparent substrate made of a light-transmissible material; a spot-like light source mounted on at least one end of the light conductive member; and a frame held to the transparent substrate so as to cover the light conductive member and the spot-like light source, characterized in that the frame generally comprises: a base plate facing an end surface of the transparent substrate with the light conductive member and the spot-like light source interposed therebetween; two opposing plates continuous with the base plate and opposing each other so as to clamp a portion toward the end surface of the transparent substrate; and two extension plates bent at both ends of at least one of the two opposing plates so as to face each other with at least one of the two extension plates having a spring force working toward the other extension plate.
