Kind Code:
A
Abstract:
To provide an actuator device that is capable of making a driven part perform an operation which cannot be performed in a case where only a driving part drives the driven part.SOLUTION: An actuator device 10 comprises: a polymer actuator 14; a permanent magnet 20; and a plurality of ferromagnetic materials 22. The polymer actuator 14 generates a movement of a rotational motion by temperature variation, and moves a camera 12 with the generated motion. The permanent magnet 20 is provided in the camera 12. The respective ones of the plurality of ferromagnetic materials 22 are provided on a foundation 24, and are arranged at an interval from each other in a direction vertical to an axial core C1. Each of the plurality of ferromagnetic materials 22 is arranged at a position where the camera 12 should be stopped. Thus, the camera 12 can be stopped at a position where one of the plurality of ferromagnetic materials 22 lies opposite the permanent magnet 20.SELECTED DRAWING: Figure 1
