    • The invention provides a beam scanner comprising a light-emitting element, a lens disposed forwardly of the light-emitting element in such a manner that its optical axis is parallel to the optical axis of the light-emitting element, and a rocking reflective mirror which is rotated by Coulomb force acting between static electrodes. There also is provided a beam scanner comprising a light-emitting element, a lens disposed forwardly of the light-emitting element in such a manner that its optical axis is parallel to the optical axis of the light-emitting element, and a displacement mechanism for reciprocal displacement of either the light-emitting element or the lens in a direction generally perpendicular to the optical axis thereof. The beam scanner of the invention is compact and permits reciprocal scanning.
    • 本发明提供了一种光束扫描器,其包括发光元件,以其光轴平行于发光元件的光轴的方式设置在发光元件的前方的透镜,以及摇摆反射镜, 通过在静电极之间作用的库仑力旋转。 还提供了一种光束扫描器,其包括发光元件,以与光发射元件的光轴平行的方式设置在发光元件的前方的透镜,以及用于 发光元件或透镜在大致垂直于其光轴的方向上的往复位移。 本发明的光束扫描器是紧凑的并且允许相互扫描。
