Pointer structure |
摘要 |
A pointer structure including: a pointer main body 55 arranged for propagating a ray of light, incident from a light source through a light incident region 65 provided closer to a pointer base end, to a pointer visualizing portion 81 closer to a tip thereof; a light-receiving portion 91 provided in the light incident region 65 in one of opposite surfaces of the pointer main body 55; a recess 97 provided in the other surface of the pointer main body 55 and having an inclined bottom surface 93 whose backside serves as a reflection surface 95 for a ray of light incident through the light-receiving portion 91; and extension portions 101 provided in the light incident region 65 in respective side surfaces 99 sandwiched between the one surface and the other surface. |

1. A pointer structure comprising:
a pointer main body configured to propagate a ray of light, incident through a light incident region provided closer to a pointer base end, to a pointer visualizing portion closer to a tip thereof; a light-receiving portion provided in the light incident region in one surface of opposite surfaces of the pointer main body; a recess provided in another surface of the opposite surfaces of the pointer main body and having an inclined bottom surface whose backside serves as a reflection surface for a ray of light incident through the light-receiving portion; and extension portions provided in the light incident region in respective side surfaces sandwiched between the one surface and the another surface. |
