Abstract
An actuator includes a closed space defined by a deformable member in which an amount of thermally expansible gas is filled. In the closed space, there is also a substance which changes the light into the heat. A control device is set to establish the supply of the light into the closed space. Upon turning-on of the control device, the substance changes the supplied light into the heat, resulting in that the resultant heat brings the expansion of the gas. Thus, the member is brought into deformed condition. The deformation can be used as a force for operating a specific element.
