본 고안은 사용자 개개인의 시도에 따라 명시 거리에 맞도록 EVF(ELECTRIC VIEW FINDER)렌즈의 위치를 조절하여 촬상곽에 맺혀진 상의 거리를 간편하게 조절하여 보다 선명한 촛점이 착상되는 화상이 나타날수 있도록 한 뷰파인더시도 조절장치에 관한 것이다.The present invention adjusts the position of the EVF (ELECTRIC VIEW FINDER) lens to suit the specified distance according to the individual's attempt, and easily adjusts the distance of the image formed on the image frame so that a clearer image can be seen. It relates to a diopter adjustment device.
종래에는 EVF 렌즈의 촛점거리가 고정되어 있으므로 사용자 개개인의 명시 거리가 다를 경우에 촛점거리를 조절할 수 없는 결점으로 인하여 화면이 흐르게 나타나게 되는 결점이 있었다.Conventionally, since the focal length of the EVF lens is fixed, there is a defect that the screen appears to flow due to a defect in which the focal length cannot be adjusted when the explicit distances of individual users are different.
본 고안은 종래의 결점을 보완하기 위하여 고안된 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to supplement the conventional drawbacks and will be described in detail with reference to the accompanying drawings.
하측 카바(1) 내부에 반구면을 이루는 가이드(2)(2a)를 돌설하고 상기 가이드(2a)의 앞 뒤쪽에 각각 장방형의 가이드홈(4)과 구멍(12)이 형성되어 있다.Guides 2 and 2a constituting a hemisphere are formed inside the lower cover 1, and rectangular guide grooves 4 and holes 12 are formed in front and rear of the guides 2a, respectively.
또한 링형슬라이드관(3)의 내부에는 EVF 렌즈(6)와 렌즈카바(7)를 결합하고 슬라이드관(3)의 주표면에 돌설된 돌기(3a)는 가동캠(5)의 원통내면에 나선형을 이루는 캠홈(5a)에 삽입되게 축방향의 삽입구멍(8)을 통해 결합시킨 다음 캠홈(5a)의 밖으로 노출된 상기 슬라이드관(3)의 돌기(3a)가 하측카바(1)의 가이드(2)(2a)사이에 형성된 가이드홈(4)에 삽입되도록 복통식 가동캠(5)의 후방단차부(9)가 카바가이드(2)면에, 가동체(5)의 중간단차부(10)가 가이드(2a)면에 접동하도록 조립되며 이때 가동캠(5)의 톱니부(11)가 하측 카바에 뚫은 구멍(12)으로 노출되도록 한 것이다. 도면중 미설명부호 (13)은 상측카바, (14)은 물체(CRT), (15)는 반사경, (16)은 후드를 나타낸다.In addition, the EVF lens 6 and the lens cover 7 are coupled to the inside of the ring-shaped slide tube 3, and the projection 3a protruding from the main surface of the slide tube 3 is spirally formed on the cylindrical inner surface of the movable cam 5. The protrusion 3a of the slide tube 3 exposed through the axial insertion hole 8 to be inserted into the cam groove 5a constituting the cam groove 5a and then out of the cam groove 5a is guided by the lower cover 1 2) The intermediate step portion 10 of the movable body 5 is provided with the rear step portion 9 of the double barrel type movable cam 5 on the surface of the cover guide 2 so as to be inserted into the guide groove 4 formed between the two grooves 2a. ) Is assembled so as to slide on the surface of the guide (2a), the tooth 11 of the movable cam (5) is exposed to the hole 12 drilled in the lower cover. In the figure, reference numeral 13 denotes an upper cover, 14 denotes an object CRT, 15 denotes a reflector, and 16 denotes a hood.
이와같이 구성된 본 고안은 제2도와 같이 조립된 상태에서 촬상관(14)과 EVF렌즈(6)의 거리를 후드(16)를 통하여 눈으로 확인하면서 제3도내지 제5도에서와 같이 버튼카바(1)의 구멍(12)으로 노출된 가동캠(5)의 톰니부(11)를 화살표방향으로 좌측회전시켜 주게 되면 상기 가동캠(5)의 원통내면에 형성된 나선형캠홈(5a)의 축방향 나선이동량 만큼 슬라이드관(3)의 돌기(3a)가 버튼카바(1)의 가이드홈(4)에 유도되어 슬라이드관(3)내부의 렌즈(6)가 후방으로 이동하게 되고 가동캠의 톱니부를 우측방향으로 회전시켜 주면 EVF렌즈(6)가 전방으로 이동하게 됨으로써 사용자 개개인의 시도에 따라 렌즈의 위치조절을 자유자재로 조절하면서 물체(14)상에 맺혀진 화상을 선명하게 볼 수 있도록 한 것이다.The present invention constructed as described above has the button cover 1 as shown in FIGS. 3 to 5 while visually confirming the distance between the imaging tube 14 and the EVF lens 6 through the hood 16 in the assembled state as shown in FIG. 2. When the tomney part 11 of the movable cam 5 exposed by the hole 12 of the left side is rotated leftward in the direction of the arrow, the axial helical movement amount of the spiral cam groove 5a formed in the cylindrical inner surface of the movable cam 5 is rotated. The projection 3a of the slide tube 3 is guided to the guide groove 4 of the button cover 1 so that the lens 6 inside the slide tube 3 moves to the rear and the teeth of the movable cam move to the right. When rotated, the EVF lens 6 is moved forward, so that the image formed on the object 14 can be clearly seen while adjusting the position of the lens freely according to the individual's attempt.
이상과 같이 본 고안은 상하측카바 내부에 설치한 가동캠의 회전운동에 따라 이 가동캠의 나선형 캠홈에 삽입된 EVF렌즈의 슬라이드관 돌기가 하측카바의 가이드홈을 따라 직선운동하는 간단한 구조로서 렌즈위츠를 조절하여 물체(CRT)에 맺혀진 화상을 선명하게 볼 수 있도록 한 정점이 있는 것이다.As described above, the present invention is a simple structure in which the slide tube projection of the EVF lens inserted into the spiral cam groove of the movable cam moves linearly along the guide groove of the lower cover according to the rotational movement of the movable cam installed inside the upper and lower side covers. There is a vertex that adjusts the wit so that the image on the object (CRT) can be seen clearly.
