Abstract:
1. An actuator comprising: a planar movement body that is capable of moving within a specified plane, a movable element side magnetism generating element which is installed on the planar movement body along a first axial direction within a specified plane, a supporting carrier which has a guide portion that guides the planar movement body in the first axial direction, said supporting carrier being capable of moving along with the planar movement body in a second axial direction while guiding a movement of the planar movement body, the second axial direction being the opposite from the first axial direction, a fixed element side magnetism generating element which is installed on an outside of the supporting carrier and is disposed in the second axial direction within the specified plane, and a magnetic path member which is disposed on the supporting carrier and has a plurality of magnetic paths that are formed between a first magnetic field of the movable element side magnetism generating element and a second magnetic field of the fixed element side magnetism generating element, the first magnetic field being disposed in the first axial direction and the second magnetic field being disposed in the second axial direction; and wherein said planar movement body is caused to move in a specified plane by a cooperative action of a magnetic field created by said fixed element side magnetism generating element and a magnetic field created by said movable element side magnetism generating element.
