摘要： A light beam L from a laser source 62 impinges upon a deflection mirror surface 651 from the direction of a pivot axis (sub scanning direction Y) at an acute angle γ with respect to the surface normal NL to the deflection mirror surface 651, and the light beam scans in a main scanning direction X. Since the light beam is incident upon the deflection mirror surface 651 along the direction of the pivot axis, the length of a movable plate 653 in the main scanning direction X may be relatively short. Further, a first optical system 63 shapes the light beam incident upon the deflection mirror surface 651 into an elongated cross sectional shape which is long in the main scanning direction X, and the movable member 653 is finished as an elongated strip which elongates in the main scanning direction X. Hence, the movable plate 653 is light-weight and can pivot stably at a faster speed than in a conventional apparatus.
摘要翻译：来自激光源62的光束L相对于偏转镜表面651的相对于表面法线NL以锐角γ从枢轴（副扫描方向Y）的方向入射到偏转镜面651，光束沿主扫描方向X扫描。由于光束沿着枢转轴线的方向入射到偏转镜面651上，所以可动板653在主扫描方向X上的长度可能相对较短。此外，第一光学系统63将入射在偏转镜面651上的光束成形为在主扫描方向X上长的细长横截面形状，并且可移动部件653被完成为在主体中伸长的细长条因此，可移动板653重量轻并且能够以比传统装置更快的速度稳定地枢转。

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。
