Japanese Patent JP3135137
Kind Code:
B2
Abstract:
PURPOSE:To surely prevent the light matching function of the illuminating display body from being lost by forming a prism in the part of the display body where light is ought to be transmitted, thereby regulating the irradiation direction of the light. CONSTITUTION:The light from a light source refracts and changes its progressing direction at the time of transmitting the prism part 1a when this light passes through a light guide 4. The direction where the light past the bottom end of, for example, the light guide 4 transmits a display mark 3 is limited to a range of A' from A in Fig. and the light past the end face of the light guide 4 from the position upper the same progresses by always facing downward from the direction shown by A. Then, the prism part 1a acts effectively to project the light only to the required range from the spacing between the fine reflection points 3b of the display mark 3 when the irradiation of the range shown by theta in Fig. with light is prohibitive.
