Patent ID: 8070304

Claim:
A camera lens unit comprising: a first lens including a first lens section having a first optical axis along which light runs, a first flange provided on an outer circumference of the first lens section, a first cylindrical section extending from the first flange along the first optical axis; and a second lens including a second lens section having a second optical axis along which the light runs, a second flange provided on an outer circumference of the second lens section and having a surface facing the first lens, and a second cylindrical section having an inner circumference extending from the second flange along the second optical axis, the inner circumference of the second cylindrical section facing the first lens, wherein, within a range between the second flange and a top end of the second cylindrical section, an outermost circumference of the first lens contacts the inner circumference of the second cylindrical section and is engaged into the second cylindrical section, wherein the second cylindrical section includes a plurality of protrusions protruding along the second optical axis, such that a plurality of crenels are provided between the protrusions and have heights along the second optical axis lower than the protrusions, and wherein a light shield sheet is located on the surface of the second flange and on the plurality of crenels of the second cylindrical section, wherein the light shield sheet does not extend along the second optical axis as high as the protrusions, wherein the first cylindrical section is remotely located from the first lens section and extends toward the second lens, wherein the second cylindrical section is remotely located from the second lens section and extends toward the first lens, wherein the first cylindrical section contacts the inner circumference of the second cylindrical section so that the first lens is engaged into the second cylindrical section, wherein a combined width of the protrusions defined by a circumferential direction of the cylindrical section is less than a combined width of the crenels.
