Abstract
A meter device includes a rotation shaft, a pointer provided in an end part of the rotation shaft and rotating integrally with the rotation shaft, an illumination light source which outputs visible rays to the pointer, a light source of infrared rays which is arranged in parallel to the illumination light source and outputs the infrared rays to the pointer, and a reflection part provided in the pointer to substantially reflect the visible rays into the pointer and to substantially pass and output the infrared rays from a central part of rotation of the pointer.
Claims6
A meter device comprising:
- a rotation shaft;
- a pointer provided in an end part of the rotation shaft and rotating integrally with the rotation shaft;
- an illumination light source which outputs visible rays to the pointer;
- a light source of infrared rays which is arranged in parallel to the illumination light source and outputs the infrared rays to the pointer;
- and
- a reflection part to which the visible rays outputted from the illumination light source and the infrared rays outputted from the light source of infrared rays are simultaneously guided through the rotation shaft and which is provided in the pointer to substantially reflect the visible rays into the pointer and to substantially pass and output the infrared rays from a central part of rotation of the pointer.
