20080199177 | IRIS DIAPHRAGM MECHANISM - A fixed aperture and a fixed shaft are formed in a fixed member. A drive shaft is formed in a driving member. A fixed shaft hole and a drive shaft hole are formed in a plurality of diaphragm blades, and the plurality of blades is connected to the fixed shaft and the drive shaft. An aperture diameter of a variable aperture AP which is an aperture zone formed by the plurality of diaphragm blades is controlled by rotating relatively the driving member with respect to the fixed member. Here, the diaphragm blades are disposed in a plurality of layers, and a part of) the diaphragm blades belonging to an adjacent layer are disposed to be overlapping with respect to an optical axis direction. | 08-21-2008 |
20090073578 | INCIDENT-LIGHT CONTROLLING APPARATUS - An incident-light controlling apparatus has a first aperture | 03-19-2009 |
20100027094 | LIGHT CONTROLLING APPARATUS, CONTROL UNIT OF LIGHT CONTROLLING APPARATUS, AND METHOD OF DRIVING LIGHT CONTROLLING APPARATUS - A method of driving light controlling apparatus which includes a substrate, which has an aperture, a plurality of incident-light controlling unit which are displaced on the substrate, a plurality of driving unit which exert on the incident-light controlling unit, an aperture-displacing driving force which displaces the incident-light controlling unit to an aperture position, and a retracting-displacement driving force which displaces the incident-light controlling unit to a retracted position which is different from the aperture position, and in which, the incident-light controlling unit is displaced by the driving unit to the aperture position and the retracted position alternately, and incident light passing through the aperture is adjusted, and the displacement of each incident-light controlling unit to the aperture position is exclusive for the other incident-light controlling unit, includes a step of displacing the incident-light controlling unit, which includes a step of displacing a first incident-light controlling unit disposed at the aperture position, to the retracted position, and a step of displacing a second incident-light controlling unit disposed at the retracted position, to the aperture position, after completion of the step of displacing the first incident-light controlling unit to the retracted position. | 02-04-2010 |
20100181463 | LIGHT CONTROL APPARATUS - A light control apparatus for controlling incident light passing through an aperture includes a substrate having the aperture, a plurality of incident light control members that are moved respectively in different planes perpendicular to an optical axis direction on the substrate, a plurality of drive members that drive the incident light control members, and separating members that separate, with a certain gap, moving spaces in which the plurality of incident light control members moves in the respective planes. The plurality of incident light control members are each moved by the drive members between an aperture position and a retracted position away from the aperture position. | 07-22-2010 |
20110002023 | LIGHT CONTROLLING APPARATUS AND OPTICAL SYSTEM - A light controlling apparatus includes 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. The incident-light controlling means is displaced to a retracted position of being retracted from the position of the aperture, by supplying an electric power supply, 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 the optical axis. | 01-06-2011 |
