摘要： A mirror driver drives deflection mirror surfaces into a pivoting action at a frequency belonging to a first drive frequency band in which the high-frequency side of a first resonance frequency band partially overlaps the low-frequency side of a second resonance frequency band, so that the deflection mirror surfaces deflect a light beam. Hence, the deflection angles of light beams change, while canceling out each other the changes of the deflection angles of the light beams deflected by the deflection mirror surfaces owing to changes of resonance characteristics. Because of this, even when the resonance characteristics change, it is possible to stabilize the deflection angle of the light beam deflected by the first deflection mirror surface and further deflected by the second deflection mirror surface.

摘要翻译： 反射镜驱动器将偏转镜面驱动成属于第一驱动频带的频率的转动动作，其中第一共振频带的高频侧部分地与第二共振频带的低频侧重叠，使得 偏转镜面偏转光束。 因此，由于共振特性的变化，光束的偏转角变化，同时抵消由偏转镜面偏转的光束的偏转角的变化。 因此，即使在谐振特性变化的情况下，也可以使由第一偏转镜面偏转的光束的偏转角稳定，并进一步被第二偏转镜面偏转。
