Abstract
An actuator according to the present invention includes a supportthat supports a driven unit, and outer axis driver units DSa, DSb that are separate and independent from the supportand configured to rotate the support. This configuration allows providing a sufficient rotational driving force around the outer, second axis AXby reducing size and weight of the related rotatable components and thus by reducing rotational moments thereof, and also allows increasing the resonance frequency of the support. As such, the actuator according to this embodiment provides a high-performance drive operation such as a raster scanning operation, for example.
