ABSTRACT:
An electromagnetically controllable pivoting device for pivoting a reflecting surface of a pivoting mirror about pivotal axes parallel to said surface with the aid of electrical control signals, more particularly intended for a video disc player in which a light beam is produced by means of a light source, which beam is aimed at an information track of a rotating optically readable video disc by means of the reflecting surface of the pivoting mirror. The mirror is supported by a bellows body of an elastically deformable plastic, which bellows body is provided with at least one rotation-symmetrical fold which is concentric with the optical center of the reflecting surface.
