*도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of drawing
1 : 셔터군 2 : 전군렌즈군1: Shutter group 2: All lens group
5 : 프론트 무버 발레 11 : 차광필름5: front mover ballet 11: shading film
12 : 차광부재12: light blocking member
본 고안은 줌 카메라의 차광구조에 관한 것으로서, 보다 상세하게는 프론트 무버 바렐과 셔터군의 틈새로 들어오는 광선을 차단할 수 있도록 하는 줌 카메라의 차광구조에 관한 것이다.The present invention relates to a light blocking structure of a zoom camera, and more particularly, to a light blocking structure of a zoom camera that can block light rays coming into a gap between a front mover barrel and a shutter group.
일반적으로 줌잉 작동되는 고배율의 카메라, 특히 셔터군을 전군렌즈군과 후군렌즈군의 사이에 개재 설치하는 비트윈 렌즈셔터 방식의 줌 카메라는 바렐에 형성된 직선홀에 캠 바렐의캠홀을 관통하는 프론트 무버 바렐의 돌기가 삽입되도록하여 캠 바렐의 회전시 프론트 무버 바렐이 전, 후진 이동될 수 있도록 하고, 또한 상기 프론트 무버 바렐의 일측부에 장착되는 셔터군 일측단부의 헬리코이드에 의해 전, 후진 이동하는 전군렌즈군을 설치하여 카메라의 줌잉 작동이 이루어지도록 하고 있다.In general, a high magnification camera that operates zooming, especially a bit win lens shutter type zoom camera in which a shutter group is installed between a front lens group and a rear lens group, has a front mover barrel that penetrates a cam hole of a cam barrel through a straight hole formed in the barrel. The front mover barrel is moved forward and backward when the cam barrel is rotated so that the projection of the cam barrel is rotated. An all-lens group is installed to allow the camera to zoom.
그런데, 이와 같은 종래의 줌 카메라는 프론트 무버 바렐과 셔터군을 조립하는 과정에서 틈새가 발생하게 되며, 또, 줌 카메라는 중잉 작동을 위한 부품이 설치되므로 다수개의 구멍들이 존재하게 된다.However, such a conventional zoom camera has a gap in the process of assembling the front mover barrel and shutter group, and the zoom camera has a plurality of holes because parts for heavy operation are installed.
이러한 틈새와 구멍들을, 종래에는 별도의 부품으로 시임 (Seam) 작업을 하여 매웠다.These gaps and holes were conventionally filled with seams as separate parts.
그러나 종래의 방법은 생산성이 저하될 분 아니다, 특히 셔터와 프론트 무버 바렐 사이의 틈을 확실하게 매우는 것이 어려워 제품 불량률이 증가하는 문제점이 있다.However, the conventional method does not reduce productivity, in particular, it is difficult to reliably fill the gap between the shutter and the front mover barrel, and thus there is a problem that the product defect rate increases.
이 고안은 상기한 바와 같은 종래의 문제점을 해소하기 위하여 안출된 것으로서, 이 고안의 목적은 프론트 무버 바렐과 셔터군의 틈새로 입사되는 유해 광선을 차단할 수 있도록하여 양호 사진의 촬영을 가능하게 하는줌 카메라의 차광구조를 제공하는데 있다.This invention was devised to solve the above-mentioned problems, and the object of this invention is to make it possible to block harmful rays incident to the gap between the front mover barrel and the shutter group, so that it is possible to take a good picture. To provide a light shielding structure of the camera.
이를 실현하기 위하여 이 고안은 셔터 개폐레버의 작동 부위를 제외한 셔터군의 외주에 차광 필름을 부착토록 하고, 이와 같은 셔터군의 프론트 무버 바렐의 장착 경계부에 차광부재를 부착하여 외부이 유해광선이 셔터군과 프론트 무버 바렐 의 틈새로 입사되지 못하도록 함을 특징으로 하고 있다.In order to realize this, the present invention allows a light shielding film to be attached to the outer periphery of the shutter group except for the operating part of the shutter opening and closing lever, and a light shielding member is attached to the mounting boundary of the front mover barrel of the shutter group so that the harmful light is emitted to the outside of the shutter group. It is characterized in that it is prevented from entering into the gap between the and front mover barrel.
이하, 이 고안이 바람직한 실시예를 첨부한 도면에 따라서 더욱 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
제1도와 제2도는 이 고안에 의한 줌 카메라의 차광구조를 나타내는 도면으로서, 섹터(도시생략)들이 조립되어 군을 이루고 있는 셔터군(1)을 전군렌즌(2)와 후군렌즈(3)의 사이에 개재 장착토록 하되, 상기한 바와 같은 셔터군(1)은 그 일측단부에 헬리코이드(4)에 의하여 전, 후진 이동이 가능한 전군렌즈군(2)을 장착한 상태로 프론트 무버 바렐(5)의 일측단부에 장착하고, 프론트 무버 바렐(5)의 돌기(6)가 캠 바렐(7)의 캠홀(8) 관통하는 상태로 바렐(9)의 직선홀(10)에 삽입되도록하여 카메라의 줌잉 작동을 가능하도록 하는 줌 카메라의 있어서, 상기한 바와 같은 프론트 무버 바렐 (5)과 셔터군(1)의 틈새로 입사되는 유해한 광선을 차단하기 위하여 셔터군(1)의 외주면에 차광 필름(11)을 부착하고, 프론트 무버 바렐(5)의 장착 경계부의 위치로 차광 필름(11)의 상면에 차광부재(12)를 부착하여 외부의 유해광선 차단할 수 있도록 하고 있는데, 상기한 차광부재(12)는 스폰지재로 형성함이 바람직하다.1 and 2 are views showing the light shielding structure of the zoom camera according to the present invention, in which the shutter group 1 in which the sectors (not shown) are assembled to form a group of the front lens range 2 and the rear lens 3. The shutter group 1 as described above is interposed between the front mover barrel and the front lens mover group 2 equipped with a front lens group 2 capable of moving forward and backward by a helicoid 4 at one end thereof. 5) and the projection 6 of the front mover barrel 5 is inserted into the straight hole 10 of the barrel 9 while penetrating the cam hole 8 of the cam barrel 7. A zoom camera for enabling zooming operation of a light shielding film on the outer circumferential surface of the shutter group 1 in order to block harmful rays incident to the gap between the front mover barrel 5 and the shutter group 1 as described above. 11) and attach the image of the light shielding film 11 to the position of the mounting boundary of the front mover barrel 5. By attaching the shielding member 12 in there, and to block the external light remains, it is the above-described light-blocking member 12 is preferably also formed of a sponge material.
이러한 구조에 의해 차광필름(11)은 셔터군(1)의 외주에 뚫려진 구멍들을 매울 수 있으며, 차광부재(12)는 프론트 무버 바렐과 셔터 사이의 틈으로 유입되는 광을 차단할 수 있다.By such a structure, the light blocking film 11 may fill holes formed in the outer circumference of the shutter group 1, and the light blocking member 12 may block light introduced into the gap between the front mover barrel and the shutter.
특히, 차광부재(12)를 스폰지로 하는 것은 틈의 크기가 일정하지 않으므로 탄력성이 있는 재질로 하므로서 차광효과를 더욱 높이기 위한 것이다.In particular, the sponge to the light-shielding member 12 is to increase the light-shielding effect by making the elastic material because the size of the gap is not constant.
이와 같은 이 고안에 의한 줌 카메라의 차광구조는 셔터군과 프론트 무버 바렐과 틈새를 통하여 입사되는 유해 광선을 차단할 수 있도록 함으로써 양호한 사진의 촬영 상태를 기대할 수 있는데 그 이점이 있다.Such a light shielding structure of the zoom camera according to the present invention is capable of blocking a harmful light incident through the shutter group, the front mover barrel, and the gap, thereby providing a favorable state of photographing.
