Claims

[Scope of utility model registration request]

It has a light source and a light guide whose positions are fixed, and a pointer that is attached to a rotation axis of a meter body and is rotatable along the scale of a scale plate, and the light guide has an entrance port and an exit port. formed so as to be able to transmit and diffuse incident light from the light source at the entrance port to the exit port,
The pointer is made of a light-guiding material and has a base portion that is attached to the rotating shaft, and a tip portion that is formed thinly and can indicate the scale, and an entrance port is disposed in the base portion facing the exit port of the light guide body. is formed, an opening facing the observer is formed at the tip, a reflective surface is formed on at least the back surface of the pointer facing the opening, and light entering the pointer and transmitted through the pointer is formed. A pointer device characterized in that at least a portion of the reflected light is reflected within the pointer and projected from the opening.
