Abstract
An optical scanner has a coil and a reflection face. This optical scanner also has: a movable plate positioned at its neutral position in a stop state; torsion bars connected to the movable plate; a support body turnably supporting the movable plate by means of the torsion bars; and a restriction member disposed at a position spaced with a predetermined distance from a surface of the movable plate. The restriction member comes into physical contact with the movable plate when a shock is applied to the optical scanner. The restriction member restricts a displacement of the movable plate equal to or greater than a predetermined quantity. The movable plate is turned with the torsion bars being a turning axis.
