본 고안은 비디오 테이프 레코오더의 어퍼드럼(UPPER DRUM)에 착설된 헤드와 오디오콘트롤 헤드와의 간격을 적정하게 조절하여주는 비디오 테이프레코오더의 오디오콘트롤헤드 간격조절장치에 대한 것이다.The present invention relates to an audio control head spacing device of a video tape recorder that properly adjusts the distance between an audio control head and a head mounted on an upper drum of a video tape recorder.
종래에는 어퍼드럼의 헤드와 오디오콘트롤헤드와의 간격을 조절하기 위해서 외주면이 경사지게 성형된 조정구를 회전시켜 조정구가 승강작동되면 그 경사면에 접촉된 조정판이 경사면을 따라 좌우로 이동되어 그 상부에 설치된 콘트롤헤드의 위치가 변경되므로 어퍼드럼에 착설된 헤드와의 간격이 조절되도록 하였다.Conventionally, in order to adjust the distance between the head of the upper drum and the audio control head, the outer peripheral surface is rotated to form an inclined control unit. Since the position of the head is changed, the distance from the head mounted on the upper drum is adjusted.
그러나 이는 조정구의 외주면이 비록 경사지게 성형은 되어 있으나, 경사면이 평활한 면으로 되어 있기 때문에 조정구를 회전시켜 조정판을 이등되게 조절을 한후에는 레코어더의 작동시의 진동등에 의해 조정판이 상하로 진동되므로, 이에 따라 오디오콘트롤 헤드도 상하로 움직이게 되는데 그 움직이는 폭이 극히 적은 상태라 해도 어퍼드럼의 헤드와의 간격이 적정위치를 벗어나 엇갈리게 되므로 녹화상태가 불량하게 되는 결점이 있었다.However, this is because the outer peripheral surface of the adjusting tool is formed to be inclined, but since the inclined surface is a smooth surface, after adjusting the adjusting plate by rotating the adjusting tool, the adjusting plate is vibrated up and down by the vibration of the recorder. As a result, the audio control head is also moved up and down. Even though the width of the audio control head is extremely small, the gap between the head of the upper drum and the head of the upper drum is shifted out of the proper position.
본 고안은 이와 같은 점을 해결하기 위해 조정구의 경사진 외주면에 나선홈을 형성하고 이에 접촉되는 조정판의 접촉면을 경사지게 형성하여 조정구의 회전에 따라 조정판이 좌우회동됨과 동시에 나선홈에 접촉면이 감착되어 상하 요동이 되지 않도록 고안한 것으로 첨부도면에 의거 상술하면 다음과 같다.The present invention forms a spiral groove on the inclined outer circumferential surface of the adjusting tool and inclined the contact surface of the adjusting plate to be inclined to solve this point, the control plate is rotated left and right according to the rotation of the adjusting device and the contact surface is depressed to the spiral groove, It is designed so that it does not rock, and according to the accompanying drawings, it is as follows.
안내로(2)를 사이에 두고 어퍼드럼(3)과 격리되게 오디오콘트롤헤드(1)를 메인데크(4)에 설치함에 있어 헤드(1)의 저부에 스프링(6)으로 탄력설치되게 착설한 조정판(5)의 접촉면(5')을 경사지게 성형하여 조정구(7)의 경사 외주면에 형성한 나선홈(7')에 감착 괘지되게 하여서 된 것이다.When the audio control head 1 is installed on the main deck 4 so as to be isolated from the upper drum 3 with the guide path 2 interposed therebetween, the bottom of the head 1 is elastically installed by the spring 6. The contact surface 5 'of the adjusting plate 5 is formed to be inclined so as to be attached to the spiral groove 7' formed on the inclined outer circumferential surface of the adjusting tool 7.
미설명 부호, "8"은 조정용 드라이버이고, "9"테이프 안내핀이다.Reference numeral "8" is an adjustment driver and "9" tape guide pin.
이와 같이된 본 고안은 비데오테이프 레코오더의 어퍼드럼(3)에 설치된 헤드와 콘트롤헤드(1)와의 간격을 조정할 필요가 있을 때에는 제2도와 같이 드라이버(8)로 조정구(7)를 회전시키면 회전되는 상태에 따라 경사외면에 의해 조정판(5)이 제3도의 가상선과 같이 회동이 된다.The present invention as described above, when it is necessary to adjust the distance between the head and the control head (1) installed in the upper drum (3) of the video tape recorder, as shown in Figure 2 by rotating the adjusting device (7) with a screwdriver 8 According to the state which becomes, the adjustment board 5 rotates like the virtual line of FIG. 3 by the inclined outer surface.
이와 같은 상태로 조정구(7)를 회전시켜 콘트롤헤드(1)를 좌측 또는 우측으로 회동시켜서 어퍼드럼(3)에 설치된 헤드와의 간격을 적정하게 조정하면 되는 것으로 일단 조정구(7)를 회전시키면 경사진 외주면에 나선홈(7')이 형성되어 있기 때문에 접촉면(5')이 이에 감착괘지 되므로 작동중진동이 발생되어도 조정판(5)이 상하로 진동되지 않고 항상조정된 상태로 고정되어 있게 되어 오디오콘트롤헤드(1)가 어퍼드럼(3)헤드와 적정간격을 유지하고 있게 되어 종래와 같이 이들의 간격이 틀려져 발생되면 녹화나 재생시의 불량을 간단히 해결할 수 있는 매우 효과적인 고안이다.In such a state, the adjuster 7 can be rotated to rotate the control head 1 to the left or right to properly adjust the distance from the head installed in the upper drum 3. Since the spiral groove 7 'is formed on the outer circumferential surface of the picture, the contact surface 5' is squeezed on it. Therefore, even if vibration occurs during operation, the adjustment plate 5 is fixed in a fixed state without being vibrated up and down. When the control head 1 maintains a proper distance from the upper drum 3 head, and the gaps thereof are generated differently as in the related art, it is a very effective design that can easily solve the defects during recording or playback.
