| titleOfInvention | Lens driving device and optical pickup device |
| abstract | PROBLEM TO BE SOLVED: To provide a lens driving device that has a very simple drive mechanism configuration, is free from heat generation, and can realize low vibration, low power consumption, and low noise. A polymer actuator 120 is used as a drive source. The polymer actuator 120 is configured by laminating a gel electrode layer and a gel electrolyte layer. When a potential is applied between the gel electrodes, ions are localized and an electric attractive force or repulsive force is generated. This force causes deformation in the direction perpendicular to the film surface. Both ends of the polymer actuator 120 are fixed to the film mounting portion 421 of the housing 400. On the polymer actuator 120, the bottom surface of the lens holder 221 supported by the guide shaft 223 so as to be displaceable is fixed. When the polymer actuator 120 is bent by applying an electric potential, the lens holder 221 is driven in the optical axis direction. [Selection] Figure 8 |
