Description
본 발명은 의료용 카메라에 관한 것으로, 보다 상세하게는 물체를 촬영하는 상태에서도 용이하게 렌즈의 촛점을 맞출 수 있음은 물론 렌즈의 촛점을 맞추는 과정에서 렌즈가 오염되는 것을 방지하여 사용자에게 제품의 신뢰성을 높일 수 있는 의료용 카메라에 관한 것이다.The present invention relates to a medical camera, and more particularly, it is possible to easily focus the lens even in the state of photographing an object, as well as to prevent contamination of the lens in the process of focusing the lens to improve the reliability of the product to the user. It relates to a medical camera that can be raised.
일반적으로, 카메라는 여러 분야에서 사용되고 있으며, 최근에는 과학기술의 발달로 인하여 의료용이나 산업용에도 많이 사용되고 있다. 의료용에는 모발, 피부, 홍체, 치아, 자궁 등을 검사 및 진단하는데 사용되고 있으며, 산업용에는 반도체 등과 같이 정밀분야에 많이 사용되고 있다.Generally, cameras are used in various fields, and recently, due to the development of science and technology, they are also used in medical and industrial fields. For medical purposes, it is used to examine and diagnose hair, skin, iris, teeth, uterus, and the like, and is used in precision fields such as semiconductors for industrial purposes.
도 1은 종래기술에 따른 의료용 카메라시스템의 구성을 보인 사시도이다. 도 1을 설명하면, 장방형의 형상을 갖는 본체(2)가 구비되어지고, 이 본체(2)의 전면 일측에는 본체(2)를 선택적으로 제어하는 조작부(4)가 장착되어진다. 케이블(6)에 의하여 본체(2)와 연결되는 카메라(8)가 구비되어지고, 이 카메라(8)의 일측에는 물체를 촬영하는 렌즈(10)가 나사결합되어진다. 본체(2)와 연결되어 카메라(8)에서 촬영된 물체의 화상을 디스플레이하는 모니터(12)가 구비되어진다.1 is a perspective view showing the configuration of a medical camera system according to the prior art. Referring to FIG. 1, a main body 2 having a rectangular shape is provided, and an operation unit 4 for selectively controlling the main body 2 is mounted on one side of the front surface of the main body 2. A camera 8 connected to the main body 2 is provided by a cable 6, and a lens 10 for photographing an object is screwed to one side of the camera 8. A monitor 12 connected with the main body 2 to display an image of an object photographed by the camera 8 is provided.
상기와 같이 구성된 의료용 카메라시스템이 작동되는 상태를 간략하게 설명한다.The operating state of the medical camera system configured as described above will be briefly described.
먼저, 어떠한 물체를 촬영하기 위해서는 본체(2)의 조작부(4)에 구비된 전원스위치(미도시)를 "온" 상태로 변환시킨다. 조작부(4)의 전원스위치가 "온" 상태로 변환되면, 전원이 본체(2)로 공급된다. 전원공급으로 인하여 본체(2)가 작동되면,카메라(8)를 촬영하고 싶은 물체의 전방에 위치시킨다. 이때, 카메라(8)에서 촬영된 화상이 모니터(12)를 통하여 디스플레이된다. 카메라(8)를 이용하여 물체를 촬영하는 도중 렌즈(10)의 촛점을 조절할 경우에는 렌즈(10)를 선택적으로 정방향 및 역방향으로 회전시키면, 렌즈(10)의 촛점이 선택적으로 조절된다. 즉, 렌즈(10)가 카메라(8)에 나사결합되어 있음으로 렌즈(10)를 선택적으로 회전시키면, 렌즈(10)의 촛점이 조절되는 것이다.First, in order to photograph any object, the power switch (not shown) provided in the operation unit 4 of the main body 2 is switched to the "on" state. When the power switch of the operation unit 4 is switched to the "on" state, power is supplied to the main body 2. When the main body 2 is operated by the power supply, the camera 8 is positioned in front of the object to be photographed. At this time, an image captured by the camera 8 is displayed through the monitor 12. In the case of adjusting the focus of the lens 10 while photographing an object using the camera 8, if the lens 10 is selectively rotated forward and reverse, the focus of the lens 10 is selectively adjusted. That is, when the lens 10 is selectively rotated because the lens 10 is screwed to the camera 8, the focus of the lens 10 is adjusted.
상기와 같이 구성된 카메라시스템을 이용하여 물체를 촬영할 수 있었지만, 이러한 카메라는 물체를 촬영하는 렌즈의 촛점을 조절하기가 매우 불편하였다. 즉, 렌즈의 촛점을 조절할 경우에는 카메라를 물체의 전방에서 이탈시킨 상태에서 렌즈를 회전시켜 렌즈의 촛점을 조절하였지만, 이러한 경우 렌즈의 촛점이 맞았는지를 확인하여야 하는 작업을 여러번 반복하여야만 원하는 렌즈의 촛점을 맞출 수 있음으로 사용자가 렌즈의 촛점을 맞추기가 매우 불편하였다.Although it was possible to photograph the object using the camera system configured as described above, such a camera was very inconvenient to adjust the focus of the lens for photographing the object. In other words, when adjusting the focus of the lens, the lens was adjusted by rotating the lens while the camera was separated from the front of the object. However, in this case, it is necessary to repeat the operation several times to check whether the lens is in focus. Since it was possible to focus, it was very inconvenient for the user to focus the lens.
또한, 렌즈의 촛점을 조절하는 도중 사용자에 의하여 렌즈가 오염되는 경우가 종종 발생하였으며, 이러한 오염으로 인하여 선명한 화상을 제공받지 못하는 경우가 종종 있었다.In addition, the lens is often contaminated by the user while adjusting the focus of the lens, and the image is often not provided due to such contamination.
이에 본 발명의 따른 상술한 문제점을 감안하여 안출한 것으로, 그 목적은 물체를 촬영하는 상태에서도 용이하게 렌즈의 촛점을 맞출 수 있음은 물론 렌즈의 촛점을 맞추는 과정에서 렌즈가 오염되는 것을 방지하여 사용자에게 제품의 신뢰성을 높일 수 있는 의료용 카메라를 제공함에 있다.In view of the above-described problems of the present invention, the object of the present invention is to easily focus the lens even in the state of photographing the object, as well as to prevent the lens from being contaminated in the process of focusing the lens To provide a medical camera that can increase the reliability of the product.

상기와 같이 구성된 의료용 카메라가 사용되는 상태 및 이에 따른 효과를 설명한다.The state in which the medical camera configured as described above is used and the effects thereof will be described.
먼저, 몸체(30)와 커버(56)의 하단에 결합된 광케이블(66)의 타측을 광원장치(미도시)와 연결한 상태에서 광원장치를 "온" 상태로 변환시킨다. 광원장치가 "온" 상태로 변환되면, 렌즈(33)의 자유단을 촬영하고 싶은 물체의 전방에 위치시킨다. 렌즈(33)의 자유단이 촬영하고 싶은 물체의 전방에 위치되면, 물체의 화상이 렌즈(33)와 화상인식소자(50)를 거쳐 모니터(미도시)를 통하여 디스플레이된다. 렌즈(33)에 의하여 촬영된 화상중에 원하는 화상이 촬영되면, 커버(56)의 일측에 장착된 정지버튼(64)을 가압하면, 렌즈(33)에 의하여 촬영된 화상이 모니터를 통하여 정지된 상태로 출력된다. 즉, 의료용 카메라(70)를 물체에 위치시키면, 물체의 화상이 모니터를 통하여 동영상으로 디스플레이되고, 촬영하고 있는 도중 정지버튼(64)을 가압하면, 모니터를 통하여 정지된 화상이 디스플레이되는 것이다.First, the other side of the optical cable 66 coupled to the lower end of the body 30 and the cover 56 is connected to a light source device (not shown) to convert the light source device to the "on" state. When the light source device is switched to the "on" state, the free end of the lens 33 is positioned in front of the object to be photographed. When the free end of the lens 33 is positioned in front of the object to be photographed, an image of the object is displayed via a monitor (not shown) via the lens 33 and the image recognition device 50. When a desired image is captured among the images photographed by the lens 33, when the stop button 64 mounted on one side of the cover 56 is pressed, the image photographed by the lens 33 is stopped through the monitor. Is output. That is, when the medical camera 70 is placed on the object, an image of the object is displayed as a moving image through the monitor, and when the stop button 64 is pressed while shooting, the still image is displayed through the monitor.
물체를 촬영하는 도중 렌즈(33)의 촛점을 조절할 경우, 커버(56)의 상단에 형성된 절개부(58)를 통하여 일측이 외측으로 돌출구성된 간격조절부(58)를 선택적으로 회전시키면 렌즈(33)의 촛점이 선택적으로 조절된다. 즉, 화상인식소자(50)가 결합고정된 이송브라켓(40)에 형성된 제 1가이드공(44) 및 제 2가이드공(46)에 일단이 몸체(30)의 제 2결합공 및 제 3결합공에 고정되고, 타단이 커버(56)의 제 4결합공(60) 및 제 5결합공(62)에 삽입고정된 가이드핀(68)에 이동가능하게 결함됨과 동시에 이송브라켓(40)의 나사공(42)에 간격조절부(54)의 나사축(52)이 치합되어 있음으로 간격조절부(54)를 정방향 및 역방향으로 회전시키면, 화상인식소자(50)와 렌즈(33)의 거리가 조절됨으로 렌즈(33)의 촛점을 용이하게 조절할 수 있는 것이다.In the case of adjusting the focus of the lens 33 while photographing an object, the lens 33 is rotated by selectively rotating the gap adjusting unit 58 having one side protruding outward through the cutout 58 formed at the top of the cover 56. ) Focus is selectively adjusted. That is, one end of the second coupling hole and the third coupling hole of the body 30 in the first guide hole 44 and the second guide hole 46 formed in the transfer bracket 40 to which the image recognition device 50 is coupled and fixed. It is fixed to the ball, and the other end is movably defective in the guide pin 68 inserted into the fourth coupling hole 60 and the fifth coupling hole 62 of the cover 56 and at the same time the b of the transfer bracket 40 Since the screw shaft 52 of the gap adjusting portion 54 is engaged with the thread hole 42, when the gap adjusting portion 54 is rotated in the forward and reverse directions, the distance between the image recognition element 50 and the lens 33 is increased. By being adjusted, the focus of the lens 33 can be easily adjusted.
간격조절부(54)의 회전에 따라 용이하게 렌즈(33)의 촛점이 조절됨으로 카메라(70)를 사용하는 상태에서도 용이하게 렌즈(33)의 촛점을 맞출 수 있음은 물론 렌즈(33)의 촛점을 조절하는 과정에서 렌즈(33)가 오염되지 않는 것이다.Since the focus of the lens 33 is easily adjusted according to the rotation of the gap adjusting unit 54, the focus of the lens 33 can be easily focused as well as the focus of the lens 33 can be achieved even when the camera 70 is used. In the process of adjusting the lens 33 is not contaminated.
상술한 바와 같이 본 발명에 따른 의료용 카메라는 몸체의 상단에 렌즈의 촛점을 용이하게 조절할 수 있는 간격조절부가 회전가능하게 구비되어 있음으로 카메라를 사용하는 상태에서도 용이하게 렌즈의 촛점을 맞출 수 있음은 물론 렌즈의 촛점을 조절하는 과정에서 렌즈가 오염되는 것을 방지할 수 있는 효과를 갖는 것이다.As described above, the medical camera according to the present invention is rotatably provided with a gap adjusting part that can easily adjust the focus of the lens on the top of the body, so that the lens can be easily focused even when the camera is used. Of course, in the process of adjusting the focus of the lens will have an effect that can prevent the lens from being contaminated.
