Abstract
An apparatus includes an image sensor unit, a retaining member configured to retain the image sensor unit on a photographer side and to retain an 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.
Claims20
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.
