Needle pointer type meter

A needle pointer type meter, comprising:

• an index plate having a first through-vision section and indexes surrounding the first through-vision section;
• a movable body which has a second through-vision section corresponding to the first through-vision section;
• a drive device for moving the movable body;
• a needle pointer which is attached to the movable body and moves along the indexes around the first through-vision section;
• a light source for illuminating the needle pointer;
• and
• a display device for displaying predetermined information to an observer through the first and second through-vision sections, characterized in that:
• the light source is formed by a plurality of light sources disposed at certain intervals along the movement route of the needle pointer, and the needle pointer is made of light-transmissive material which receives light from a given light source of the plural light sources in accordance with the movement of the needle pointer so that the needle pointer can emit light.
