Abstract
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.
