HOLDER OF LOW PROFILE FOR COMPACT CARMERA MODULE

摘要

A low profile holder of a compact camera module is provided to be designed so that the diagonal length of an IR(Infrared Ray) filter junction supporting part is longer than a diameter of an internal side of a lens barrel coupling part by forming the tetragonal IR filter junction supporting part between the lens barrel coupling part and an image sensor cover part. A lens barrel coupling part(30) couples a lens barrel of a camera module. An image sensor cover part(31) is located in a lower end of the lens barrel coupling part(30). The image sensor cover part(31) protects an image sensor for converting a beam inputted through a lens into an electric image signal. An IR filter junction supporting part(32) is processed as a tetragonal shape between the lens barrel coupling part(30) and the image sensor cover part(31). The length of the processed tetragonal diagonal is formed to be longer than a diameter of an internal side of the lens barrel coupling part(30) at 0.2mm or more. A cylindrical part of the lens barrel coupling part(30) is exposed to the processed tetragonal edge part. The IR filter junction supporting part(32) is formed at thickness close to the thickness of an IR filter(40) including an IR filter safety-receiving part capable of safely receiving the IR filter(40) when the IR filter(40) is attached.
