摘要： A 2-axis driving electromagnetic scanner, having a structure in which a mirror is separated from a driving unit and directly driven, is provided. The electromagnetic scanner includes: an outer driving unit which is capable of rotating around a first axis; an inner driving unit which is suspended from the outer driving unit so as to rotate around a second axis perpendicular to the first axis; and a stage which is located on an upper surface of the inner driving unit so as to rotate together with the inner driving unit. In the electromagnetic scanner, the stage is connected to the inner driving unit by a link unit protruding from a center of a lower surface of the stage.
