Abstract
An oscillator device includes an oscillation system having first and second oscillators and first and second resilient supporting members, wherein the oscillation system has at least two frequencies of natural oscillation mode around a torsion axis which include a first resonance frequency fand a second resonance frequency f, wherein there is a relationship that fis approximately two-fold of f, and wherein a drive control member supplies, to a driving member, a driving signal which is comprised of a driving signal based on synthesizing a first driving signal having a first driving frequency and a second driving signal having a second driving frequency, and which is such driving signal that, among the first and second driving frequencies, a lower-frequency side driving frequency Dfand a higher-frequency side driving frequency Dfsatisfy a relationship1×2=2and that Dfsatisfies a relationship2−|Δ/2|<2<2+|Δ/2|.
