ABSTRACT:
This invention relates to an indicating instrument for a vehicle or the like in which a pointer-indicated driving condition such as vehicle speed and rotation speed of an engine is formed by light, and to an indicating instrument system having the above indicating instruments. The structure of the indicating instrument is that a front surface having graduations is spherical such that the front surface sticks out forwardly as it is far from the rotation shaft and a light source is disposed in front of the dial and out of the graduations. Further, the indicating instrument system of the present invention indicates a cylindrical lens for converting beam from a point light source to a substantially linear beam; first and second reflecting plates for dividing the substantially linear beam into divided beam; and third and fourth reflecting plates for reflecting the divided beams each to a dial as a pointer indicating the graduations on the dial to a plurality of pointer forming portions.
