Patent ID: 8717652

Claim:
A micro scanner device comprising: a fixing frame serving as an outer frame; a first axis portion and a second axis portion having axis directions different from one another; a holder having a cantilever beam structure in which a first end of the holder is connected to the second axis portion and a second end of the holder is fixed to the fixing frame; a drive portion generating, in response to a voltage applied thereto, a force for deforming the holder; a moving portion swinging with respect to the first axis portion according to displacement of the first axis portion, the moving portion swinging with respect to the second axis portion according to displacement of the second axis portion; and a drive circuit applying to the drive portion a voltage, the voltage being configured to cause deformation of the drive portion, the deformation of the drive portion being configured to cause the deformation of the holder, the deformation of the holder being configured to cause displacement of both the first axis portion and the second axis portion, the displacement of both the first axis portion and the second axis portion being configured to cause a first rotation of the moving portion with respect to the first axis portion and a second rotation of the moving portion with respect to the second axis portion, the first rotation being made with resonance at higher speed than the second rotation, wherein the drive circuit applies to the drive portion a voltage having a frequency that is approximate to or equal to a natural frequency of the micro scanner itself and that generates in the holder at least one node intersecting with respect to a length of the holder.
