본 고안은 비디오 인터폰용 카메라의 C.C.D 렌즈 화각 조절장치에 관한 것으로, 본인의 선 출원고안 제 90-863호 및 제 90-2019호의 개량고안이다.The present invention relates to a C.C.D lens angle of view adjustment device for a video intercom camera, which is an improvement of the prior applications Nos. 90-863 and 90-2019.
위 선출원 고안들은 소형모터의 구동력 또는 수동으로 캠을 회전시켜 이 캠에 편심 연결되거나, 별도 요동구에 의해 렌즈 고정판이 상하 좌우로 요동되게 함으로써, 렌즈가 그 요동각만큼 경사진 상태로 궤도회전을 하게 됨에 따라 광범위한 화각을 얻을 수 있게 한 것인데, 렌즈의 궤도 회전운동을 가능케하는 구성요소가 복잡하여, 오동작 발생률이 높고, 부품수가 많아져 제품단가가 높아지는 단점이 지적된다.The above-mentioned applications have eccentrically connected to the cam by rotating the cam manually or by the driving force of the small motor, or by allowing the lens fixing plate to swing up and down and left and right by a separate swing hole, so that the lens is orbitally rotated by the swing angle. As a result, it is possible to obtain a wide angle of view, the components that enable the orbital rotational movement of the lens is complicated, the malfunction rate is high, the number of parts is pointed out the disadvantage that the product cost increases.
본 고안은 렌즈 화각조절장치에 있어서 위와 같은 제폐단점들을 해결하기 위해 안출된 것으로, 렌즈의 요동각을 궤도 회전운동에 의하지 않고 단순한 상, 하, 좌, 우 위치 조작에 의하여 얻을 수 있도록 카메라케이스 본체의 뒷판상에 로타리식 안내홈을 형성하여 렌즈고정판 뒷면 중앙에 연결된 조절봉을 위 안내홈에 선택적으로 끼우면 렌즈가 일정각도로 경사지게 되어 보다 광범위한 화각을 얻을 수 있게 한 것으로써, 이를 첨부도면에 의거 상세하게 설명하면 다음과 같다. 도면 제1도는 본 고안의 요부를 발췌한 절개 사시도로서, 케이스 본체 전면 커버(1)의 투시공(1') 후면 중앙에 렌즈(3)가 위치되도록 렌즈고정판(4)을 지지하는 브라켓(2')이 배판(2)상에 부착 설치되고, 렌즈고정판(4)은 앞쪽이 핀(5')으로 좌우요동링(5)을 통하여 브라켓(2')에 유동가능하게 연결되며, 렌즈고정판(4) 후면 중앙에 조절봉(6)을 설치하여 배판(2)상에 상, 하, 좌, 우의 4방향으로된 ""형 또는 8방향의 ""형으로 형성시킨 로타리형 안내홈(7)에 선택적으로 끼워지게 구성한 것으로, 미 설명부호 8은 조절 손잡이이다.The present invention has been devised to solve the above-mentioned decontamination points in the lens angle of view adjustment device, the camera case body so that the swing angle of the lens can be obtained by simple up, down, left, right position operation without using the orbital rotational movement. Rotary guide grooves are formed on the rear panel of the lens to selectively insert the adjusting rod connected to the center of the back of the lens fixing plate into the guide grooves, and the lens is inclined at a certain angle to obtain a wider angle of view. It will be described in detail as follows. 1 is a cut-away perspective view of the main part of the present invention, a bracket (2) for supporting the lens fixing plate (4) so that the lens (3) is located at the center of the rear view hole (1 ') of the case body front cover (1) ') Is attached to the back plate (2), the lens fixing plate (4) is connected to the bracket (2') through the left and right rocking ring (5) to the front of the pin (5 ') so as to be movable. 4) Install the adjustment bar (6) in the center of the rear panel on the back panel (2) in four directions of up, down, left, right "Shaped or eight-way" "It is configured to be selectively fitted in the rotary guide groove 7 formed in the shape, reference numeral 8 is an adjustment knob.
도면 제2도 (a) (b)는 전면 커버(1)의 투시공(1')상에 렌즈(3)가 정중앙에 위치된 도시한 배면도 및 측단면도로서, 이 때는 조절봉(6)이 로타리식 안내홈(7)의 중심부분에 위치되어 있다. 이 상태에서 렌즈(3)의 화각을 좀 더 상향 또는 하향시키기를 원할때에는 조절봉(6) 끝단에 구비된 조절 손잡이를 이용하여 제3 (a) (b) 혹은 제4도 (a) (b)와 같이 조절봉(6)을 로타리형 안내홈(7)의 상부 또는 하부위치로 이동시키게 되던 브라켓(2') 및 좌우요동링(5)에 의해 렌즈 고정판(4)이 상, 하 요동되어 렌즈(3)는 전면커버(1) 상투시공(1')에서 상부 또는 하부로 경사지게 됨에 따라 상, 하로 화각의 범위가 확장되는 것이며, 좌, 우의 화각범위의 조절봉(6)을 로타리식 안내홈에서 좌, 우로 이동시키면 된다.(A) and (b) are rear and side cross-sectional views of the lens 3 positioned centrally on the see-through hole 1 'of the front cover 1, in which case the adjusting rod 6 is shown. It is located in the center of the rotary guide groove (7). In this state, if you want to raise or lower the angle of view of the lens 3 further, use the adjusting knob provided at the end of the adjusting rod 6 to adjust the third (a) (b) or the fourth degree (a) (b). The lens fixing plate 4 is moved up and down by the bracket 2 'and the left and right rocking ring 5 which move the adjusting rod 6 to the upper or lower position of the rotary guide groove 7 as shown in FIG. The lens (3) is inclined upward or downward from the front cover (1) upper and lower construction (1 ') to expand the range of view angles up and down, the rotary rod guides the adjustment bar (6) of the left and right angle of view range You can move left and right at home.
한편 렌즈와 각의 보다 큰 광범위화를 원할 경우에는 로타리형 안내홈(7)을 ""형으로 형성함으로써 위 목적을 달성할 수 있다. 이와같이 본 고안은 간단한 구성으로 이루어져 고장률이 적고, 제품단가를 낮출 수 있으며, 그 사용방법이 극히 단순하여 쉽게 사용할 수 있게 된 비디오 인터폰용 카메라의 C.C.D 렌즈 화각 조절장치를 제공하는 효과가 있다.On the other hand, if you want a wider range of lenses and angles, turn the rotary guide groove (7) " "The above object can be achieved by forming a shape. As such, the present invention has a simple configuration, which has a low failure rate, lowers the cost of the product, and uses the CCD of a camera for a video intercom, which is very simple to use. It is effective to provide a lens angle of view adjustment device.
