PROBLEM TO BE SOLVED: To provide a pointer instrument capable of illuminating a pointer by light from a light source, with which it is possible to inject light to a pointer base part while being unaffected by the position of the light source.SOLUTION: Behind a pointer 3 is arranged seven light sources 8 on a circumference around the axis of rotation L1 of the pointer 3. Four of the seven light sources 8 emit white light, and the remaining three emit red light. Between a boss part 34 of the pointer 3 and the light sources 8 is provided a light guide part 6 that is separate from the pointer 3. The light guide part 6 is formed in such a shape that the light received by a light receiving part 61 is converged at a center position where the axis of rotation L1 is located. A control part causes the three of the seven light sources 8 to emit light, and changes a combination of the light sources 8 caused to emit light in accordance with a vehicle speed. In a first speed area three white light sources 8 are made to emit light, in a second speed area higher in speed than the first speed area two white light sources 8 and one red light source 8 are made to emit light, and in a third speed area higher in speed than the second speed area three red light sources 8 are made to emit light.SELECTED DRAWING: Figure 2

    【課題】光源からの光により指針を照明することができる指針計器において、光源の位置の影響を抑制した形で指針基部に光を入射できる指針計器を提供する。【解決手段】指針3の背後には、指針3の回転軸線L1を中心とした円周上に7個の光源8が配置される。7個の光源8のうち4個は白色光を発し、残り3個は赤色光を発する。指針3のボス部34と光源8との間に指針3と別体の導光部6が設けられる。導光部6は受光部61で受光した光を回転軸線L1が位置する中央位置にて集束する形状に形成される。制御部は、7個の光源8のうち3個を発光させるとともに、車速に応じて発光させる光源8の組み合わせを変化させる。第1の速度領域では3個の白色光の光源8を発光させ、第1の速度領域よりも高い第2の速度領域では2個の白色光の光源8及び1個の赤色光の光源8を発光させ、第2の速度領域よりも高い第3の速度領域では3個の赤色光の光源8を発光させる。【選択図】図2
