Abstract
A pointer of a meter is driven by a driving unit disposed behind a scale plate. A wiring board for supplying electric current to a stepping motor included in the driving unit is placed between the scale plate and the driving unit. Plural light sources for illuminating the pointer are placed on the wiring board around a pointer shaft in the vicinity thereof. Terminal pins for supplying electric current to the stepping motor are positioned on the wiring board apart form the light sources to avoid wiring congestion around the pointer shaft. Since the light sources are freely placed around the pointer shaft, the light from the light sources can be uniformly distributed around the pointer shaft with high luminance.
