Patent ID: 7894113

Claim:
An actuator, comprising: a first oscillatory system including a frame-shaped driving member and a pair of first axial members holding the driving member so as to allow the driving member to rotate around an X-axis; a second oscillatory system including a movable plate provided inside the frame of the driving member and a pair of second axial members holding the movable plate to the driving member so as to allow the movable plate to rotate around a Y-axis perpendicular to the X axis; and a driving unit including a permanent magnet of longitudinal shape provided on the driving member, a coil provided so as to face the permanent magnet, and a voltage applying unit applying first and second voltages to the coil, wherein, the permanent magnet is provided such that the longitudinal line of the permanent magnet is slanted with respect to each of the X-axis and the Y-axis, in a plan view of the movable plate, and the voltage applying unit applies the first and second voltages to the coil, and the movable plate is rotated both of around the X-axis and around the Y axis.
