Patent ID: 8040584

Claim:
A light controlling apparatus comprising: a substrate in which an optical aperture is formed; a first light controlling means and a second light controlling means, each having an optical aperture regulating portion; and a drive source which moves the first light controlling means and the second light controlling means, wherein the first light controlling means and the second light controlling means move mutually to a first stationary position retracted from a position of the optical aperture, and a second stationary position which overlaps with a position of the optical aperture, and a single rotating shaft member is formed integrally with the first light controlling means, and a coupling portion is formed on at least one of the first light controlling means and the second light controlling means, and the first light controlling means is rotated by rotating the single rotating shaft member by the drive source, a rotational movement of the first light controlling means is transmitted to the second light controlling means by contacting mechanically the first light controlling means and the second light controlling means via the coupling portion, and the second light controlling means is also rotated turned in conjunction by the coupling portion, and the first light controlling means and the second light controlling means rotate with the same axis of rotation as a center of rotation.
