Patent ID: 8411341

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 a first axis; a second oscillatory system including a movable member provided inside the frame of the driving member and a pair of second axial members holding the movable member to the driving member so as to allow the movable member to rotate around a second axis perpendicular to the first 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 a voltage 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 first and the second axis, in a plan view of the movable member, the movable member has a circular shape in the plan view, and the movable member is rotated around both the first axis and around the second axis.
