ABSTRACT:
A light controlling apparatus includes 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 operates the first light controlling means and the second light controlling means. 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 the position of the optical aperture. A rotating shaft member is formed integrally with the first light controlling means. 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 rotating shaft member by the drive source, and the second light controlling means is also rotated in conjunction by the coupling portion. The first light controlling means and the second light controlling means rotate with the same axis of rotation as a center of rotation.
