Patent ID: 7852539

Claim:
An actuator, comprising: a first vibrating system having a frame-like driving member and a pair of first axis members holding the driving member so that the driving member is rotatable about an X axis; a second vibrating system having a movable plate provided inside the frame of the driving member and a pair of second axis members holding the movable plate on the driving members so that the movable plate is rotatable about a Y axis orthogonal to the X axis; a driving unit including a permanent magnet of longitudinal shape provided on the driving member, a coil provided to oppose the permanent magnet and a voltage applying unit applying voltage to the coil; and a spacer sandwiched between the driving member and the permanent magnet so as to form space between the permanent magnet and the movable plate, the permanent magnet being provided such that the longitudinal line of the permanent magnet inclines, in a plan view of the movable plate, with respect to the X axis and the Y axis, and the voltage applying unit applying voltage to the coil so that the movable plate rotates both about the X axis and about the Y axis.
