Description

렌즈 고정장치Lens holder

본 발명은 탄성부재를 사용하여 렌즈를 쉽고 확실하게 고정할 수 있는 렌즈 고정장치에 관한 것이다.The present invention relates to a lens fixing apparatus that can easily and reliably fix a lens using an elastic member.

일반적으로 카메라나 망원경 또는 현미경 등의 광학제품에 있어서는 다수의 오목렌즈와 볼록렌즈를 조합하여 피사체로부터 반사된 빛을 받아 필름편 또는 촬상면에 도립상 또는 정립상으로 초점을 맺게한다.In general, in an optical product such as a camera, a telescope or a microscope, a plurality of concave lenses and convex lenses are combined to receive light reflected from a subject to focus on an inverted or upright image on a film piece or an imaging surface.

상기와 같은 광학제품에는 다수의 오목렌즈와 볼록렌즈를 조합하여 고정하고 보호하며 렌즈를 구동하기 위하여 경통이 사용된다.In such an optical product, a barrel is used to fix, protect, and drive the lens by combining a plurality of concave and convex lenses.

종래 카메라의 경통 어셈블리에 렌즈를 고정하기 위한 방법으로는 경통의 내면에 렌즈가 장착되는 렌즈 삽입부를 계단형상으로 형성하고 상기한 렌즈 삽입부에 렌즈를 삽입한 다음 상기 렌즈 삽입부의 개방된 쪽을 별도의 부품인 렌즈 고정링 등을 사용하여 막아서 렌즈를 고정하는 방법이나, 상기한 렌즈 삽입부에 렌즈를 삽입할 때에 열코킹을 행하거나 접착제를 등을 사용하여 렌즈를 고정하는 방법이 주로 사용된다.In order to fix the lens to the barrel assembly of a conventional camera, the lens insert is formed in a step shape in which the lens is mounted on the inner surface of the barrel. The lens is inserted into the lens insert, and then the open side of the lens insert is separated. The method of fixing a lens by blocking it using a lens fixing ring or the like, or the method of fixing a lens by thermal caulking or by using an adhesive or the like when the lens is inserted into the lens insertion unit is mainly used.

상기와 같이 이루어지는 종래의 렌즈 고정방법은 별도의 부품을 사용하거나 열코킹 또는 접착 등의 방법으로 렌즈를 고정하므로, 렌즈를 경통에 조립하는 공정이 복잡하게 이루어지고 부품수가 많기 때문에 생산성이 저하되고 제조원가가 상승한다는 문제가 있다.In the conventional lens fixing method as described above, since the lens is fixed by using a separate part or by a method such as thermal caulking or adhesion, the process of assembling the lens to the barrel is complicated and the number of parts is high, resulting in low productivity and low manufacturing costs. There is a problem that rises.

본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 경통의 탄성력을 이용하여 렌즈를 고정하는 렌즈 고정장치를 제공하는 것이다.An object of the present invention is to solve the above problems, to provide a lens fixing device for fixing the lens by using the elastic force of the barrel.

본 발명의 렌즈 고정은 경통 내면의 렌즈가 장착되는 위치에 소정의 힘을 가하면 접혀지고 힘이 제거되면 세워지는 탄성돌기를 형성하여 상기한 탄성돌기의 탄성력에 의하여 이루어진다.Lens fixing of the present invention is made by the elastic force of the elastic protrusions by forming an elastic protrusion that is folded when a predetermined force is applied to the position of the lens inner surface of the barrel is mounted and erected when the force is removed.

또 본 발명의 렌즈 고정장치는 내면에 렌즈가 삽입되는 렌즈 삽입부가 형성되고, 상기한 렌즈 삽입부에는 소정의 힘을 가하면 접혀지고 힘이 제거되면 세워지는 탄성돌기가 형성된다.In addition, the lens fixing device of the present invention is formed with a lens insertion portion is inserted into the lens on the inner surface, the lens insertion portion is formed when the elastic force is folded when a predetermined force is applied and the force is removed.

상기와 같이 탄성돌기가 형성된 본 발명의 렌즈 고정장치에 의하면, 렌즈를 삽입할 때에는 상기한 탄성돌기가 접혀져서 렌즈가 상기한 렌즈 삽입부로 삽입되고, 렌즈의 삽입이 완료되면 상기한 탄성돌기가 세워져서 렌즈 삽입부에 삽입된 렌즈의 모서리 부분을 탄성돌기가 지지하는 것에 의하여 렌즈의 삽입 위치가 일정하게 고정 유지된다.According to the lens fixing device of the present invention formed with an elastic projection as described above, when the lens is inserted, the elastic projection is folded so that the lens is inserted into the lens insertion portion, and when the insertion of the lens is completed, the elastic projection is raised. The insertion position of the lens is fixedly maintained by supporting the elastic protrusions on the edge portions of the lens inserted into the lens insertion section.
