PROBLEM TO BE SOLVED: To provide a galvano scanner that can easily prevent plane tilt of a galvano mirror and prevent a processing position from being displaced.SOLUTION: A magnet 33X is arranged in the vicinity of a back face of a conductive galvano mirror 35X, or arranged in the vicinity of a conductive member 32X fixed to a galvano mirror 351X. Thus, if a plane tilt occurs, a Lorentz force for suppressing the plane tilt acts on the galvano mirror 35X or on the conductive member 32X, suppressing the plane tilt. |
