Abstract
Movement of a movable portion without stopping at any moment can be achieved by a simple configuration including a beam structural portion including two beam portions extending in directions different from each other and one driving portion. Furthermore, a size reduction of a device is achieved in comparison with a case where a device includes a motor disposed for rotation driving.
