摘要 |
An oscillation system includes first and second oscillation movable elements supported by respective elastic supporting elements. The oscillation system has a first natural oscillation mode of a resonance frequency f1 and a second natural oscillation mode of a resonance frequency of f2 which is approximately N-fold of f1 where N is a natural number. A control device determines set driving frequencies Df1 and Df2 in accordance with a predetermined equation while satisfying a relation Df2=N×Df1 and drives the oscillation system at the set driving frequencies through a driving member.
