Abstract:
1. An apparatus comprising: an image sensor unit; an optical member provided closer to an object side than the image sensor unit; a vibration generation unit configured to apply vibration to the optical member; a retaining member configured to retain the image sensor unit on a photographer side and to retain the optical member on an object side; a first sealing member configured, when the image sensor unit is mounted on the retaining member, to form a closely sealed space by sealing between the image sensor unit and the retaining member, the first sealing member being provided on the photographer side of the retaining member; and a second sealing member configured, when the optical member is mounted on the retaining member, to form a closely sealed space by sealing between the optical member and the retaining member, the second sealing member being provided on the object side of the retaining member, wherein when the vibration generation unit applies vibration to the optical member, a node appears at a predetermined position of the optical member, the second sealing member contacts the optical member at the predetermined position, wherein the first sealing member and the second sealing member are provided on the retaining member separately, and wherein a bottom surface of the second sealing member is closer to the photographer side of the retaining member than a bottom surface of the first sealing member.
