20110058242 | LIGHT AMOUNT ADJUSTMENT APPARATUS HAVING PLURALITY OF PLATE-LIKE LIGHT-SHIELDING BLADE MEMBERS AND METHOD OF MANUFACTURING THE LIGHT-SHIELDING BLADE MEMBERS - A light amount adjustment apparatus having a plurality of light-shielding blade members that can be so manufactured by simple machining as to reduce undesired reflection on end faces of the light-shielding blade members which are parallel with the optical axis and prevent degradation in image quality such as flare and ghosts. A driving force of a stepping motor is transmitted to the light-shielding blade members so that an aperture diameter can be changed. The light-shielding blade members are formed by injection molding of a light-shielding resin material. By performing blasting on an end face of each light-shielding blade member in a part that forms the aperture diameter, an aperture end face whose surface is roughened while substantially maintaining outside dimensions of the light-shielding blade member is formed, and an oblique portion tilted relative to the aperture end face is formed. | 03-10-2011 |
