Abstract
A graduation board has an arc-shaped graduation portion and translucent graduations disposed along the graduation portion. A light emitting pointer is disposed on a front side of the graduation board and moves along the graduations. A plurality of LEDs that are disposed on a reverse side of the graduation board emits respective graduations. A control circuit controls an emission order of the LEDs according to the movement of the light emitting pointer when a key switch of the vehicle is turned on. As a result, the combination meter provides attractiveness and originality for the driver, when the key switch turns on.
