| 摘要 |
For providing a small-size light controlling apparatus in which a desirable opening and closing operation of a diaphragm blade is possible by driving an ion-conducting actuator by a small voltage, a light controlling apparatus is made to include a substrate in which an optical aperture is formed, a light controlling mechanism which is provided with another optical aperture and a shielding section, an actuator which generates a power which rotates the light controlling mechanism, a controlling mechanism which displaces the actuator, and a transmission member of which, one end is coupled with the light controlling mechanism, and the other end is coupled with the actuator via a coupling member, and which transmits the power of the actuator to the light controlling mechanism. The transmission member, at the time of transmitting the power, widens the displacement of the actuator.
