Patent ID: 8625185

Claim:
A light controlling apparatus comprising: a substrate having an aperture; a light controlling section which includes at least one incident-light controlling means, having a magnet joined to a position of a center of rotation, and which rotates in a plane perpendicular to an optical axial direction, on the substrate; and at least one coil which imparts a rotational force to the magnet, wherein the incident-light controlling means is displaced to a position of the aperture and a retracted position of being retracted from the position of the aperture, by supplying an electric power, and in the light controlling apparatus in which, incident light which passes through the aperture is controlled, the coil is disposed to be extended in a direction parallel to an optical axis, wherein a length of the at least one coil is longer than an outer circumferential length of an outer edge of the substrate having the aperture.
