摘要:
Disclosed is an oscillating system arranged so that a gravity center of a movable member and a torsional axis of a resilient support are easily registered with each other to prevent deformation of the movable member due to its dead weight or deviation of deformation from symmetrical deformation, wherein the oscillating system includes a substrate 301, a movable member 302 with hard magnetic members 310 and 311, resilient supports 304 and 305 for supporting the movable member for torsional vibration about a torsional axis 312 with respect to the substrate, and a magnetic field producing device for driving the movable member relative to the substrate, wherein the movable member 302 has recesses 306 and 307, and wherein the hard magnetic members are fixed while their end portions are aligned with end faces 308 and 309 corresponding to the recesses.
