摘要：
An oscillator device includes a supporting member, an oscillation system having plural oscillators and plural torsion springs, a driving device for oscillating the oscillation system, a drive control device for controlling the driving device, an oscillation detecting device for detecting a state of oscillation of an oscillator of the oscillation system, a resonance frequency calculating device for calculating a resonance frequency of the oscillation system based on an output of the oscillation detecting device, and a control parameter adjusting device for adjusting a control parameter of the drive control device, wherein the control parameter adjusting device adjusts a control parameter based on an output of the resonance frequency calculating device.
