Title:
揺動体装置及び光偏向装置
Document Type and Number:
Japanese Patent JP5184909
Kind Code:
B2
Abstract:
An oscillator device includes an oscillation system including an oscillator and a resilient supporting member, a driving member configured to supply a driving force to the oscillation system based on a driving signal, and a driving frequency control unit configured to control a driving frequency of a driving signal to be outputted to the driving member, wherein, when an oscillation frequency of the oscillator is to be changed from a current oscillation frequency to a target oscillation frequency, the driving frequency control unit temporarily outputs, to the driving member, a driving signal having a driving frequency which is made different from the target oscillation frequency, being changed from the current driving frequency and beyond the target oscillation frequency, thereby to cause the driving member to drive the oscillation system.
