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.
