Pointer structure
View Patent ↗A pointer structure including: a pointer main body formed by a light guide member and having a light guide portion closer to a light source and a light guide portion closer to a visualizing portion that are continued together through a pointer bend portion; an outer reflection surface formed at an outer corner of the pointer bend portion so that a ray of light from a light source can be incident thereon; and an inner reflection surface formed at an inner corner of the pointer bend portion and having a normal line thereof intersecting with a normal line of the outer reflection surface, the normal line of the inner reflection surface intersecting with the normal line of the outer reflection surface at an including angle θ, on a light input side, smaller than 180 degrees and greater than 90 degrees.
1. A pointer structure comprising:
a pointer main body formed from a light guide member and having a first light guide portion closer to a light source and a second light guide portion closer to a visualizing portion that are continued together through a pointer bend portion;
an outer reflection surface formed at an outer corner of the pointer bend portion so that a ray of light from the light source can be incident thereon; and
an inner reflection surface formed at an inner corner of the pointer bend portion, the inner reflection surface having a normal line thereof intersecting with a normal line of the outer reflection surface at an including angle, on a light input side, smaller than 180 degrees and greater than 90 degrees.
2. A pointer structure according to claim 1 , wherein the pointer main body includes a plurality of pointer bend portions, at least a closest one out of the pointer bend portions having the outer reflection surface and the inner reflection surface.
