ABSTRACT:
A mirror apparatus has a reflecting surface to reflect an incident luminous flux. A fixed member has a plurality of driving electrodes on a surface of the fixed member. A movable member is formed with the reflecting surface on one side, and capable of escaping out of the optical path of the incident luminous flux along the fixed member. A driving circuit is capable of applying a voltage to the driving electrodes to generate an electrostatic force between the driving electrodes and movable members. A control circuit supplies a control signal to the driving circuit to change the electrostatic force acted on the movable member.
