ABSTRACT:
An optical scanner and beam printer using the optical scanner are disclosed in which the optical scanner includes a scanning element supporting a mirror surface, a support element for freely supporting at one end the scanning element and at another end a vibrating element, and a drive source for inducing vibrations in the vibrating element. The support element may be a shaft having two modes of elastic deformation upon vibration or a torsional spring which undergoes deformation upon vibration. Vibrations received by the vibrating element are applied to the scanning element by the support element to cause optical scanning movement by the scanning element.
