PROBLEM TO BE SOLVED: To provide a pointer instrument capable of guiding light from a light source part to a drive shaft of a pointer.SOLUTION: A pointer instrument includes: a display board 120 including an information display part; a photoconductive drive shaft 141 rotatably inserted into the display board; a pointer 140 for pointing to the information display part; a drive part 160 connected to the drive shaft, so as to control the rotation of the drive shaft; a light source 171; and a light reception part 141a which is provided to the drive shaft, and which receives light from the light source, so as to conduct the light from the light source to the inside of the drive shaft. Thus, the light reception part allows the light from the light source to be conducted to the inside of the drive shaft.SELECTED DRAWING: Figure 4
【課題】光源部からの光を指針の駆動軸に導光させることのできる指針計器を提供する。【解決手段】指針計器において、情報表示部を有する表示板120と、表示板に対して回転可能に挿通された光伝導性の駆動軸141を有し、情報表示部を指し示す指針140と、駆動軸に接続されて駆動軸の回転を制御する駆動部160と、光源171と、駆動軸に設けられ光源の光を受光し駆動軸内に光源の光を伝導させる受光部141aと、を設ける。これにより、受光部によって、駆動軸内に光源の光を伝導させることができるようになる。【選択図】図4
