<P>PROBLEM TO BE SOLVED: To make light incident on a plane of a light emission plate at a target angle from a target position. <P>SOLUTION: An LED board 66 is fixed in a board storing chamber 63. A front LED 67 faces a front light incident surface 45 of a front light emitting plate 43 by fixing the LED board 66 in the board storing chamber 63, and a rear LED 68 faces a rear light incident surface 54 of a rear light emitting plate 52. This board storing chamber 63 is provided between a front cover 44 and a rear cover 53. The front cover 44 is integrally molded with the front light emitting plate 43, and the rear cover 53 is integrally molded with the rear light emitting plate 52. Therefore, as a positional relation of the front LED 67 to the front light emitting plate 43, and a positional relation of the rear LED 68 to the rear light emitting plate 52 are stabilized without variation, the light is stably made incident from the target position at the target angle to the front light incident surface 45 of the front light emitting plate 43 and to the rear light incident surface 54 of the rear light emitting plate 52. <P>COPYRIGHT: (C)2012,JPO&INPIT |
