Abstract
An imaging apparatus having an opening of a front casing caulked with a pressure member. An O-ring is used for caulking the front casing and is designed to have an inner diameter larger than the outer diameter of the first lens, and an outer diameter smaller than the inner diameter of the pressure member. When the pressure member is screw fitted, the O-ring is compressed. Thus, a clearance formed by the edge portion of the first lens and the inner wall surface of the pressure member is caulked by the deformation of the O-ring occurring when the O-ring is pressed.
Claims3
An imaging apparatus comprising:
- a camera casing having an opening;
- a lens set housed in a lens-barrel;
- and
- a pressure member in a cylindrical shape having an opening defined by an annular pressure portion, the pressure member disposed between the camera casing and the lens-barrel,
- wherein said opening of said pressure member is caulked with a first lens of said lens set by fixing said pressure member to an outer circumferential portion of said lens-barrel, and
- said opening of said camera casing is caulked by fixedly housing said fixed pressure member in said camera casing in which a front end portion of said fixed pressure member projects outside from said opening of said camera casing,
- wherein said lens set housed in said lens-barrel is a wide-angle lens set,
- said opening of said pressure member is caulked with a first lens of said wide-angle lens set, and
- said pressure member is fixedly screwed down to said outer circumferential portion of said lens-barrel in which a convex surface of said first lens projects from said opening of said pressure member to an outside of said pressure member, while an inner circumference of said pressure member is disposed to extend along an outer circumferential portion of said first lens of said lens set.
6 more elements
An imaging apparatus comprising:
- a camera casing having an opening;
- and
- a lens assembly including a lens-barrel for housing a lens set positioned relatively to each other, a pressure member in a cylindrical shape surrounding an outer circumference of said lens-barrel, and an opening defined by said pressure member, the pressure member disposed between the camera casing and the lens-barrel,
- wherein said opening of said pressure member is caulked with a first lens of said lens set by fixedly screwing said pressure member down to an outer circumferential portion of said lens-barrel, and
- said opening of said camera casing is caulked by fixedly housing said pressure member screwed down fixedly in said camera casing in which a front end portion of said pressure member screwed down fixedly projects outside from said opening of said camera casing,
- wherein said camera casing has a front casing including said opening of said camera casing, and a rear casing, and
- said lens assembly is inserted into said front casing from a rear side thereof and then fixed by screwing from said rear side, while said front casing and said rear casing are fixed by screwing from said rear side of said rear casing.
