Abstract: PURPOSE: To provide the light-weight and strong optical scanner of a compact structure with excellent assembly/operation efficiency by combining an optical element, a permanent magnet and a flexible element. CONSTITUTION: When an AC current is applied to an electromagnetic coil 82, force for vibrating a mirror/magnet assembly in a horizontal direction is generated by mutual action with the permanent magnet 94 and the flexible element 90 is bent in a twisting direction. Thus, a laser beam made to hit a mirror is deflected in the horizontal direction. A vertical moment is generated by the force generated in a leaf spring 88 by magnetically induced force and a ring 86 is moved in a vertical direction. Since a ring assembly is flexibly attached so as to be adapted to vertical movement, this scanner 80 vibrates the mirror 92 in two directions and performs raster scanning by the laser beam deflected by the mirror 92. Thus, the light-weight and string optical scanner of the compact structure with the excellent assembly/operation efficiency is obtained.
