Abstract
A first virtual axis orthogonally intersects with a second virtual axis, and a third axis (axis passing a support center point) vertical to the first and second virtual axes is permitted to be a reference axis. A magnetic drive mechanism is provided with first magnetic drive sections for applying a drive power to a movable axis, which is supporting an object to be controlled, in a rotating direction of the first virtual axis or in a rotating direction parallel to the first virtual axis, and second magnetic drive sections for applying a drive power to the movable axis, in a rotating direction of the second virtual axis or in a rotating direction parallel to the second virtual axis.
