Abstract
An imaging device support structure includes a master flange having an opening portion through which an optical axis passes, an imaging device which is directly or indirectly attached to the master flange and is positioned in the opening portion as viewed in an optical axis direction, and a shielding member which shields a gap between the master flange and the imaging device in the opening portion. The shielding member includes a slit or a groove and is pressed against an opening edge of the opening portion.
Claims23
A shielding structure, comprising:
- a first member having an opening portion through which an axis passes;
- a shielding member which shields the opening portion;
- and
- a second member which presses a part of the shielding member located inside the opening portion toward the first member along a direction of the axis,
- wherein
- at least one slit or groove is provided in the shielding member such that, when the part of the shielding member located inside the opening portion is pressed toward the first member along the direction of the axis, the shielding member is deformed so that a central portion of the shielding member protrudes forward as compared to a peripheral portion thereof and twists and warps formed in the shielding member are absorbed by the at least one slit or groove.
An imaging device support structure, comprising:
- a master flange having an opening portion through which an optical axis passes;
- an imaging device which is directly or indirectly attached to the master flange and is positioned in the opening portion as viewed in a direction of the optical axis;
- and
- a shielding member which shields a gap between the master flange and the imaging device in the opening portion,
- wherein
- the shielding member includes at least one slit or groove and is pressed against an opening edge of the opening portion along the direction of the optical axis such that, when the shielding member is pressed against the opening edge of the opening portion along the direction of the optical axis, the shielding member is deformed so that a central portion of the shielding member protrudes forward as compared to a peripheral portion thereof and twists and warps formed in the shielding member are absorbed by the at least one slit or groove.
An imaging device support structure, comprising:
- a master flange having an opening portion through which an optical axis passes;
- an attachment member attached to the master flange;
- an imaging device which is attached to the attachment member and is positioned in the opening portion as viewed in a direction of the optical axis;
- and
- a shielding member which shields a gap between the master flange and the attachment member in the opening portion,
- wherein
- the shielding member includes at least one slit or groove and is pressed against an opening edge of the opening portion in the direction of the optical axis such that, when the shielding member is pressed against the opening edge of the opening portion in the direction of the optical axis, the shielding member is deformed so that a central portion of the shielding member protrudes forward as compared to a peripheral portion thereof and twists and warps formed in the shielding member are absorbed by the at least one slit or groove.
