Patent ID: 7474165

Claim:
An oscillating device, comprising: an oscillating system having a plurality of oscillation movable elements, a plurality of resiliently supporting portions connected to said plurality of oscillation movable elements, and a supporting member for supporting a portion of said plurality of resiliently supporting portions; a coil for applying a torque to at least one of said plurality of oscillation movable elements; a driving circuit for supplying a driving signal to said coil; and a temperature adjusting element for adjusting temperatures of said plurality of resiliently supporting portions; wherein said oscillating system has a reference oscillation mode corresponding to a natural oscillation mode at a reference frequency, and a second natural oscillation mode of a frequency n-fold of the reference frequency, where n is an integer; wherein said driving circuit applies, to said coil, a driving signal of the reference oscillation mode and a driving signal of the second natural oscillation mode so as to excite the reference oscillation mode and the second natural oscillation mode simultaneously, and wherein said temperature adjusting element is configured to adjust the temperatures of said plurality of resiliently supporting portions, independently of each other.
