본 고안은 오디오.콘트롤헤드의 엑스-포지션 조정장치에 관한 것으로서 오디오. 콘트로헤드가 설치되는 헤드플레이트를 캠형상의 조정구를 유동시켜 엑스-포지션을 정확하게 조정하여 오디오. 콘트롤헤드를 주행하는 비디오 테이프의 음성기록 및 재생을 찌그러김 없이 조정할 수 있게 한 것이다.The present invention relates to an X-position control device for an audio control head. The head plate on which the contro head is installed is moved through a cam-shaped adjustment port so that the X-position can be adjusted accurately. The audio recording and playback of the videotape driving the control head can be adjusted without distortion.

일반적으로 비디오 테이프를 헤드드럼상에 로딩시키면 테이프가 헤드드럼 일측에 설치된 오디오. 콘트롤헤드면에 접면되면서 주행하는데 이때 헤드드럼과 오디오. 콘트롤헤드 사이의 거리인 엑스-포지션이 정확하게 조정되지 않으면 음성 기록 및 재생기록의 불량상태(노이즈 현상)가 발생하게 된다.Generally, the video tape is loaded on the head drum and the tape is installed on one side of the head drum. Drives on the face of the control head and the head drum and audio. If the X-position, which is the distance between the control heads, is not correctly adjusted, a bad state (noise phenomenon) of audio recording and reproduction recording occurs.

그러므로 이를 방지하기 위하여 오디오. 콘트롤헤드를 VTR셋트의 최초 사용전에 엑스-포지션을 미리 조정하여 고정설치하고 일반인들은 조정을 하지 못하도록 조정구 상면에 페이트 칠을 하여 놓는다.Therefore audio to prevent this. Before the initial use of the VTR set, the control head is pre-adjusted and fixed in place, and the paint is painted on the top of the fitting to prevent the public from making adjustments.

그러나 비디오를 장시간 사용하였을 때에는 외부충격, 흔들림 또는 헤드플레이트를 지지하여 주는 텐션스프링의 탄력에 의해 이 오디오.콘트롤헤드가 유동상태가 발생되어 엑스-포지션을 조정하여야 되는 것이다.However, when the video is used for a long time, the audio / control head is in a flow state due to external shock, shaking, or tension spring supporting the head plate, and the X-position needs to be adjusted.

종래에는 이러한 엑스-포지션 불량상태를 조정하기 위하여 엑스포지션 조정구를 설치하는데 그 예를 살펴보면, 첫째, 제4도의 (a)(b)에서 도시한 바와 같이 테크판(20)상에 나사산(21)을 형성한 조정스크류(22)에 경사면(23)을 가진 조정구(24)를 나사식으로 체결하여 설치하였고 이 조정구(24)의 경사면(23)에 헤드플레이트(25)의 일측부(26)가 접촉되어 엑스-포지션 상태를 유지하였다.Conventionally, in order to adjust such an ex-position bad state, an installation of an adjustment position adjustment apparatus is described. First, as shown in (a) (b) of FIG. 4, the thread 21 on the tech board 20 is shown. The adjusting screw 24 having the inclined surface 23 was fastened to the adjusting screw 22 formed with a screw, and one side portion 26 of the head plate 25 was provided on the inclined surface 23 of the adjusting tool 24. Contact was maintained in an ex-position.

그러나 지주(27)에 축설되어 헤드플레이트(25)의 상면에 설치된 오디오.콘트를헤드(28)의 엑스-포지션 상태를 유지하도록 하여 주는 텐션스프링(29)의 강한 탄력에 의해 장시간 탄력을 받은 조정스크류(22)가 휘어지는 폐단이 발생하고 헤드플레이트(25)가 아래 방향으로의 힘을 받게 되어 장시간에 걸쳐 변형을 가져오게 되어엑스-포지션의 조정상태를 불량하게 하거나 또는 외부의 충격에 의해 조정스크류에 체결 된 조정된(24)가 풀어져 이 조정구의 위치변동에 의해 엑스-포지션 조정상태가 불량한 상태를 유발시키는 결점이 있다.However, the adjustment was made for a long time due to the strong elasticity of the tension spring 29 that is installed in the support (27), the audio.cont installed on the upper surface of the head plate 25 to maintain the X-position state of the head 28. A closed end of the screw 22 is generated and the head plate 25 is subjected to downward force, which causes deformation over a long time, thereby deteriorating the adjustment state of the X-position or adjusting the screw by an external impact. There is a drawback that the adjusted 24 fastened to is loosened, causing the X-position adjustment state to be poor due to the positional change of the adjustment mechanism.

그리고 조정스크류에 체결된 조정구는 경사면에 의하여 엑스-포지션을 조정하므로 이 경사면을 정밀하게 가공하여야 하는 제작상에 어려움이 있다.In addition, since the adjusting tool fastened to the adjusting screw adjusts the X-position by the inclined surface, there is a difficulty in manufacturing the inclined surface precisely.

둘째는 본 출원인이 고안하여 출원한 (출원번호 90-3437호)엑스-포지션 조정장치는 VTR의 테크판 일부를 절곡시킨 절곡편에 나사공을 천공하고 이 나사공에 미세 조정나사를 체결하고 이 미세 조정나사의 끝단은 오디오. 콘트를헤드를 장착한 헤드플레이트의 일측에 형성된 경사면에 접촉시켜, 액스-포지션 불량시 조정나사를 회전시켜 엑스-포지션을 조정하였던 것이다.Second, the X-position adjusting device devised and filed by the present applicant (for the application number 90-3437) drills a screw hole in a bending piece that is bent a part of the tech plate of the VTR and tightens a fine adjustment screw in the screw hole. The tip of the fine adjustment screw is audio. The control was brought into contact with the inclined surface formed on one side of the head plate on which the head was mounted, and when the ax-position was bad, the adjusting screw was rotated to adjust the ex-position.

그러나, 상기 고안은 미세 조정나사로 엑스-포지션 조정을 정확하게 조정할 수 있으나, 지주에 설치된 텐션스프링의 탄성에 의해 절곡시킨 절곡편이 장기간 지남에 따라 점차적으로 퍼지므로 엑스-포지션 불량상태를유발시키는 폐단이 있는 것이다.However, the above-described design can precisely adjust the X-position adjustment with a fine adjustment screw, but the bending piece bent by the elasticity of the tension spring installed in the support gradually spreads over a long period of time, which leads to a poor state of the X-position. will be.

본 고안은 상기와 같은 종래의 결점을 해소시키기 위하여 조정구를 절삭 가공하기 쉬운 캠의 형상으로 형성하고, 이와 같이 형성된 조정구를 지지하여 주는 지지대를 설치하여 휘어짐을 방지하여 주어 엑스-포지션 조정의 불량상태를 방지하는 한편, 조정 또한 간편하게 할 수 있게한 것으로서 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is formed in the shape of a cam that is easy to cut the adjustment tool in order to eliminate the above-mentioned drawbacks, and by installing a support for supporting the adjustment tool formed as described above to prevent the warpage of the bad state of the X-position adjustment While preventing, while also being described in detail by the accompanying drawings as easy to adjust as follows.

(1)은 헤드플레이트이다.(1) is a head plate.

이 헤드플레이트(1)의 일측부에는 오디오헤드 및 콘트롤헤드가 장착된 오디오.콘트럴헤드(2)를 설치하였고, 헤드플레이트(1)의 끝단(3)에는, 중심축으로 부터 좌,우 거리가 각기 다른 캠형상의 조정구(4)의 중심축에 구멍(5)을 천공하고 이 조정구(4)가 삽입 설치될 수 있도록 테크편(6)에 조정구 설치부(7)가 형성된 지지대(8)를 설치하였고 조정구 설치부(7)의 내경에는 나사산(9)을 형성하여 상부로 부터 체결되는 나사(10)로서 조정구(4)와 지지대(8)를 고정시켜 접촉시켜 된 것이다.One side of the head plate 1 is provided with an audio and control head 2 equipped with an audio head and a control head. At the end 3 of the head plate 1, left and right distances from the central axis are provided. A support 8 having a hole mounting portion 7 formed in the tech piece 6 so that the hole 5 can be drilled in the center axis of the cam-shaped adjustment tool 4, and the adjustment tool 4 can be inserted therein. In the inner diameter of the adjusting device mounting portion 7 is formed by the thread (9) is a screw 10 is fastened from the top to fix the adjusting device (4) and the support (8) is to contact.

미설명 부호 12는 텐션스프링,13은 지주.Unexplained symbol 12 is tension spring, 13 is strut.

이와같이 구성된 본 고안은 테크편(6)에 설치된 지지대(8)의 조정구 설치부(7)에 조정구(4)를 삽입 설치한후 헤드플레이트(1)에 장착된 오디오. 콘트를헤드(2)와 조정구(4)와의 엑스-포지션을 조정하여 나사(10)로서 조정구(4)를 지지대(8)에 고정시킨다.The present invention configured as described is the audio mounted on the head plate (1) after inserting the adjusting tool (4) in the adjusting tool mounting portion (7) of the support (8) installed in the tech piece (6). The control is adjusted to the X-position between the head 2 and the adjuster 4 to fix the adjuster 4 to the support 8 as a screw 10.

지지대(8)에 고정설치된 조정구(4)는 지주(13)에 설치되어 헤드플레이트(1)를 지지하여 주는 텐션스프링(12)의 탄성에도 지지대(8)가 휘어지는 폐단이 없어 엑스-포지션 조정이 불량해지는 폐단이 발생하지 않는것 이다.The adjuster 4 fixed to the support 8 is installed on the support 13 so that the support 8 is not bent in the elastic spring of the tension spring 12 that supports the head plate 1, so that the ex-position adjustment is performed. It does not cause the closing of the defect.

그러나 외부의 조건 즉 흔들림등에 의해 엑스포지션조정이 불량상태가 밭생하였을 경우 조정구(4)의 상측에 체결된 나사(10)를 풀고 캠형상의 조정구(4)를 제2도에 도시한 바와 같이 회전시켜 엑스-포지션을 조정한후 다시 나사(10)를 조여 조정구(4)를 고정시키면 되는 것이다.However, in the case of poor condition adjustment due to external conditions such as shaking, loosen the screw 10 fastened to the upper side of the adjusting tool 4 and rotate the cam-shaped adjusting tool 4 as shown in FIG. After adjusting the X-position by tightening the screw 10 again to fix the adjusting holes (4).

이상에서와 같이 본 고안은 엑스-포지션의 조정을 전담하는 조정구를 캠의 형상으로 형성하므로서 조정구의 절삭가공을 간편하게 형성하여 원가절감을 할 수 있고, 또한 조정구를 2단 형상인 지지대에 설치하므로서 종래와 같이 텐션스프링에 의해 지지대가 휘어지는 폐단을 방지할 수 있으며 나사로서 조정구를 고정시키므로서 외부의 진동에 의해 엑스-포지션의 불량상태가 발생하지 않으며 캠형상의 조정구에 의해 VTR의 호완성을 향상시켜 줄 수 있게 한 매우 실용적인 고안인 것이다.As described above, the present invention can reduce the cost by easily forming the cutting process of the adjusting tool by forming the adjusting tool dedicated to the X-position adjustment in the shape of the cam, and also by installing the adjusting tool on the support having the two-stage shape. It can prevent the closed end of the support bent by the tension spring as shown in the figure. By fixing the adjusting tool with screws, the bad state of the X-position does not occur due to external vibration, and the cam-shaped adjusting tool improves the compatibility of the VTR. It is a very practical design.
