본 발명은 카메라의 아이피스 어댑터에 관한것으로 더욱 상세하게는 카메라의 뷰 파인더부에 확대경이 구비된 아이피스를 결합할 수 있는 아이피스 어댑터에 관한 것이다.The present invention relates to an eyepiece adapter of a camera, and more particularly, to an eyepiece adapter capable of coupling an eyepiece provided with a magnifying glass to a view finder of the camera.

일반적으로 카메라는 RF(레인져 파인더)방식과 SLR(일안 리플렉스)방식으로 구분할 수 있다.Generally, cameras can be divided into RF (ranger finder) and SLR (single-lens reflex) methods.

RF방식은 피사체를 감지하여 촬영되는 렌즈와 피사체를 볼 수 있는 뷰파인더가 별도로 구비된 것으로 뷰파인더와 촬영용 렌즈의 위치 사이에 오차가 발생하여 실제로 촬영되는 상과 보여지는 상에 차이가 있다는 문제점이 있는 것이다.The RF method is provided with a separate viewfinder for detecting a subject and a lens to be photographed. An error occurs between the position of the viewfinder and the photographing lens, and there is a difference between the actual image and the visible image. It is.

이에 반해 SLR방식은 피사체가 촬영되는 렌즈와 피사체를 볼 수 있는 뷰파인더가 일체로 형성된 것으로 평상시에 렌즈를 통해 들어오는 빛의 신호를 거울에 반사시켜 뷰파인더로 촬영자에게 보여주다가 셔터를 누르면 거울이 상단으로 올라가며 거울에 가려져 있던 저장매체에 도달하는 구조이므로 시차가 존재하지 않는 것이다. On the other hand, the SLR method is formed with an integrated lens and a viewfinder for viewing the subject, and reflects the light signal through the lens to the mirror and shows it to the photographer through the viewfinder. Parallax does not exist because the structure reaches the storage medium hidden by the mirror.

즉, 보여지는 그대로 촬영이 가능한 SLR구조는 빛의 신호를 제어하는 셔터의 구동부가 카메라 몸체에 형성되어 렌즈부에 형성된 RF방식의 카메라와 달리 접사, 광각, 망원, 줌 렌즈 등의 다양한 렌즈로 교환하여 사용할 수 있는 장점을 가지고 있는 것이다. That is, the SLR structure that can be photographed as it is seen is different from the RF type camera formed in the lens part by the driving part of the shutter that controls the signal of the light, which is replaced with various lenses such as macro, wide angle, telephoto, zoom lens, etc. It has the advantage of being used.

하지만 이러한 SLR카메라는 구조상 뷰파인더의 크기가 작아서 피사체가 작게 보임으로 촬영자가 뷰파인더를 통하여 피사체를 볼 때 미세한 부분까지 확인을 하 지 못하여 촬영자의 의도대로 촬영이 이루어지는데 어려움이 있고 뷰파인더 주변에 스며드는 잡광에 의하여 뷰파인더의 집중이 힘들다는 단점이 있는 것이었고 이러한 문제점을 해결하기 위하여 카메라의 확대경이나 아이피스를 카메라에 장착하기 위한 아이피스 어댑터가 제시되었다.However, the SLR camera has a small viewfinder because of its structure, which makes the subject look small. Therefore, it is difficult for the photographer to check the minute details when viewing the subject through the viewfinder. It was a disadvantage that the concentration of the viewfinder was difficult due to the infiltration of light. In order to solve this problem, an eyepiece adapter for mounting a camera magnifier or eyepiece to the camera was proposed.

그러나 아피피스 어댑터에 카메라의 확대경을 결합시 나사조임방식으로 고정하므로 결속력이 약하여 힘이 약한 사용자가 조임을 했을 경우, 또는 장시간 촬영이나 이동시에 많은 움직임에 의해 나사풀림이 현상이 일어나 분실의 위험이 있는 것이었고 이러한 분실을 방지하기 위하여 사용자가 그 조임의 강도를 강하게 하였으나 강한조임에 의하여 확대경의 탈착이 어렵다는 문제가 있는 것이었다.However, when attaching the magnifying glass of the camera to the Apispi adapter, it is fixed by screw tightening method, so when the user is weak due to weak binding force or when moving or shooting for a long time, the screw loosening occurs due to many movements. In order to prevent such loss, the user tightened the strength of the tightening, but there was a problem that it is difficult to remove the magnifying glass by the strong tightening.

이러한 문제점을 해결하기 위하여 본 발명은 어댑터의 일측에 확대경의 외주면에 형성된 널링부에 대응되는 요철부를 형성하여 확대경의 널링부가 어댑터의 요철부에 걸림되어 확대경의 풀림을 방지토록 한 것이다. In order to solve this problem, the present invention is to form an uneven portion corresponding to the knurled portion formed on the outer peripheral surface of the magnifying glass on one side of the adapter to prevent the knurled portion of the magnifying glass is caught in the uneven portion of the adapter to prevent loosening of the magnifying glass.

이하 본 발명에 따른 바람직한 실시 예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다. 하기 첨부 도면에서는 동일한 구성요소에 대해서는 동일한 참조번호를 사용하였다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. In the accompanying drawings, the same reference numerals are used for the same components.

도 1은 확대경이 아이피스에 결합되는 상태를 나타낸 분해사시도이고 도2는 카메라의 뷰파인더에 결합을 위한 끼움패드가 어댑터에 장착되는 상태의 결합사시도로서, 전방으로 전방나사산(21)이 구비된 확대경(20)이 카메라(100)의 뷰파인 더(101)에 장착되는 어댑터(10)의 암나사부(11)에 나사조임으로 결합되는 것이다.1 is an exploded perspective view showing a state in which the magnifying glass is coupled to the eyepiece, Figure 2 is a perspective view of the combination of the mounting pad is mounted on the adapter for coupling to the viewfinder of the camera, the front magnifying glass provided with a front screw 21 in the front 20 is screwed to the female threaded portion 11 of the adapter 10 mounted on the viewfinder 101 of the camera 100.

이때 어댑터(10)가 뷰파인더(101)에 끼움되기 위하여는 어댑터(10)에 일체로 끼움수단이 형성되거나 도2에 도시된 바와같이 별도의 끼움패드(10a)를 사용하여 다양한 카메라(100)의 뷰파인더(101)의 크기에 따라 각각크기에 맞는 끼움패드(10a)를 결합하여 어댑터(10)의 결합이 가능토록 할 수 있는 것이다. In this case, in order for the adapter 10 to be fitted into the viewfinder 101, a fitting means is integrally formed in the adapter 10 or various cameras 100 are formed by using a separate fitting pad 10a as shown in FIG. 2. According to the size of the viewfinder 101 of the fitting pad 10a to fit to each size will be able to be coupled to the adapter (10).

확대경(20)의 외주면으로는 어댑터(10)에 탈부착이 용이하도록 널링부(22)가 형성된 것이고 어댑터(10)의 일측으로는 확대경(20)의 널링부(22)에 대응되는 요철부(15)를 갖는 풀림방지수단(12)을 형성하여 확대경의 임의적인 이탈을 방지한 것이다.The outer circumferential surface of the magnifying glass 20 has a knurled portion 22 formed on the adapter 10 so that the adapter 10 can be easily attached and detached, and one side of the adapter 10 corresponds to the uneven portion 15 corresponding to the knurled portion 22 of the magnifying glass 20. By forming an anti-loosening means (12) having a) is to prevent the arbitrary separation of the magnifying glass.

도 3에 도시된 바와 같이 풀림방지수단(12)은 요철부(15)를 갖는 고정대(14)가 지지대(13)에 의하여 탄성력을 갖는 것으로 상기 요철부(15)는 확대경(20)의 널링부(22)와 동일선상에 위치되어 확대경(20)의 회전을 막는 것이고 확대경(20)의 탈부착을 위하여 회전을 요할 때는 풀림방지수단(12)의 고정대(14)를 누르면 고정대(14)의 요철부(15)가 어댑터(10)의 개구부(16)로 삽입되어 확대경(20)의 널링부(22)와 동일선상의 위치에서 이탈되어 확대경(20)의 회전이 가능토록 되는 것이다.As shown in FIG. 3, the anti-loosening means 12 includes a fixing member 14 having an uneven portion 15 having elastic force by the support 13, and the uneven portion 15 has a knurled portion of the magnifying glass 20. It is located on the same line as (22) and prevents the rotation of the magnifying glass 20, and when the rotation is required for the attachment and detachment of the magnifying glass 20, pressing the holder 14 of the release preventing means 12, the uneven portion of the holder 14 15 is inserted into the opening 16 of the adapter 10 so as to be separated from the same line as the knurled portion 22 of the magnifying glass 20 so that the magnifying glass 20 can be rotated.

이와 같은 풀림방지수단(12)은 도 3과 같이 요철부(15)를 갖는 고정대(14)가 지지대(13)에 의해 일체로 형성되어 탄성작용에 의해 확대경(20)의 회전을 제어토록 하는 방법과 도4에 도시된 바와 같이 어댑터(10)에 결합공(17)을 형성하여 고정대(14)를 나사결합에 의하여 어댑터(10)에 탈부착하여 확대경(20)의 회전을 제어하 는 방법으로 제작이 가능 것이다.The anti-loosening means 12 is a method for controlling the rotation of the magnifying glass 20 by an elastic action is formed integrally by the support 13 having a concave-convex portion 15 as shown in FIG. And forming a coupling hole 17 in the adapter 10 as shown in FIG. 4, by attaching and detaching the holder 14 to the adapter 10 by screwing, thereby controlling the rotation of the magnifying glass 20. This would be possible.

이때 확대경(20)의 후방으로는 피부가 금속에 마찰되는 것을 방지하고 촬영시 잡광을 차단하여 촬영에 집중하기 위하여 후방나사산(23)에 아이컵(30)을 결합하여 사용하거나 별도의 고무재질의 아이링(미도시)을 끼워서 사용을 하는 것이다.At this time, the rear of the magnifying glass 20 is used by combining the eye cup 30 with the rear screw 23 to prevent the skin from rubbing against the metal and to concentrate the shooting by blocking the light when shooting. It is used by inserting an eye ring (not shown).

상술한 바와 같이 본발명은 아이피스 어댑터에 확대경을 결합하여 사용시 확대경의 널링부가 어댑터의 풀림방지수단에 의하여 견고히 고정되어 장시간 촬영이나 이동시 많은 움직임에도 분실의 위험이 없으면서도 간단한 조작에 의해 확대경의 탈착이 이루어 지도록 한 것이다.As described above, the present invention is a knurled portion of the magnifying glass is firmly fixed by the anti-loosening means of the adapter when the magnifying glass is coupled to the eyepiece adapter, so that the attachment and detachment of the magnifying glass can be achieved by simple operation without the risk of loss even during long time shooting or moving. It is to be done.
