Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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. 2. The meter device according to claim 1 , wherein the illumination light source and the light source of the infrared rays are arranged, opposing to an end face of a base end part side of the rotation shaft. 3. The meter device according to claim 1 , wherein the pointer includes a light guide part protruding toward the illumination light source and the light source of infrared rays and having light input surfaces which allow the visible rays and the infrared rays to be incident. 4. The meter device according to claim 1 , wherein a diffusion lens which diffuses and outputs the infrared rays is provided with the pointer. 5. A meter unit comprising: the meter device according to claim 1 ; a camera which picks up an image of an irradiated member which is irradiated with the infrared rays; and a meter panel on which the meter device and the camera are installed. 6. 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 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; and a tubular light guide member into which the rotation shaft is inserted, wherein the illumination light source and the light source of infrared rays are arranged, opposing to an end face of a base end part side of the tubular light guide member, and wherein the visible rays and the infrared rays pass through the tubular light guide member and reach the reflection part.
