OSCILLATOR DEVICE AND OPTICAL DEFLECTOR USING THE SAME

摘要

An oscillator device includes at least one movable element supported for oscillatory motion around a rotational axis, and a first rectifying member for suppressing generation of a spiral airflow during oscillation of the movable element, the first rectifying member being provided to occupy a space of at least a portion of a spiral airflow generating region which might otherwise be created when the first rectifying member is not provided there.
