Abstract
A mirror control device includes a pivotally supported mirror (), electrodes (-) spaced apart from the mirror (), a driving voltage generation means () for generating a driving voltage corresponding to the desired tilt angle of the mirror () for each electrode, a bias voltage generation means () for generating, as a bias voltage for each electrode, a voltage which causes the tilt angle of the mirror () to have the same predetermined value upon being independently applied to each of the electrodes (-), and an electrode voltage applying means () for adding, for each electrode, the bias voltage to the driving voltage and applying the voltage after addition to a corresponding one of the electrodes (-).
