Abstract:
1. An instrument driving device comprising: an instrument for showing vehicle information by rotating a pointer on a display plate; a display plate illuminating means for illuminating the display plate; a plurality of light emitting section illuminating means, provided in the instrument, for illuminating a light emitting section having an area smaller than that of the display plate; and a control means that causes the instrument to perform a mood enhancement operation different from a normal displaying operation in response to an input of a predetermined start signal, and, as part of the mood enhancement operation, at least activates the display plate illuminating means and then gradually reduces the intensity of the display plate illuminating means to a non-lighted state so that the intensity changes non-linearly and the light reduction rate decreases with time, wherein, as part of the mood enhancement operation, the control means activates at least one of the plurality of light emitting section illuminating means before activating the display plate illuminating means, and then gradually reduces the intensity of the at least one of the plurality of light emitting section illuminating means to a non-lighted state so that the intensity changes non-linearly and the light reduction rate decreases with time, and after the display plate illuminating means becomes the non-lighted state, the control means individually causes the plurality of light emitting section illuminating means to blink so that the plurality of light emitting section illuminating means are activated alternately with each other.
