Abstract
An optical scanner and a two-dimensional scanning device using the same are provided. The optical scanner includes a scanning mechanism and a swing support. The swing support is designed to support the scanning mechanism on a housing so as to allow the scanning mechanism to swing and made up of a plurality of springs. The springs are so constructed so as resist unwanted vibrations acting on the optical scanner in directions different from a scan direction, thereby ensuring a stable scan of a light beam at all the time.
