Patent ID: 8537448

Claim:
A mirror actuator, comprising: a base member; a first pivot portion which is supported on the base member to be pivotally movable about an axis of a first pivot shaft; a second pivot portion which is supported on the first pivot portion to be pivotally movable about an axis of a second pivot shaft perpendicular to the first pivot shaft; a mirror which is disposed in the second pivot portion; a first coil which is pivotally moved with the first pivot portion; a second coil which is pivotally moved with the second pivot portion; a magnet portion which supplies a magnetic field to the first coil and to the second coil; a plurality of first elastic members which connect between the base member and the first pivot portion, and have flexibility and conductivity; a plurality of second elastic members which connect between the first pivot portion and the second pivot portion, and have flexibility and conductivity; and a circuit pattern which connects between one of joint portions between the first elastic members and the first pivot portion, and one of joint portions between the second elastic members and the first pivot portion, wherein the circuit pattern is configured in such a manner that a current flows from the first elastic member for supplying a signal to the second coil to the second elastic member for supplying a signal to the second coil, and the first coil is connected to an end of the first elastic member, corresponding to the side of the first pivot portion, for supplying a signal to the first coil, and the second coil is connected to an end of the second elastic member, corresponding to the side of the second pivot portion, for supplying a signal to the second coil.
