2 : A/C 헤드 지지판 5 : X 조정 너트2: A / C head support plate 5: X adjustment nut
5-1 : Y 조정 너트 고정축 6 : 스프링5-1: Y adjustment nut fixed shaft 6: Spring
본 고안은 VTR에 있어서, A/C(Audio Control) 헤드의 X 조정 너트를 직면체로 교체하고, 스프링의 탄성을 받도록 함으로써 Y 조정 너트로 A/C헤드 지지판을 조정할 때 X의 값이 변하지 않도록 한 VTR의 A/C 헤드 조정 장치에 관한 것이다.The present invention replaces the X adjustment nut of the A / C (Audio Control) head with a face in the VTR and allows the spring to be elastic so that the value of X does not change when the A / C head support plate is adjusted with the Y adjustment nut. A / C head adjusting device of the VTR.
종래에는 제 3 도에 도시한 바와 같이 X 조정 너트(11)가 사다리 꼴로 형성되어 있으므로 Y 조정 너트(12)를 좌,우로 회전시켜 A/C 헤드 지지판(13)을 화살표 방향으로 상, 하 이동시키면서 Y축 조정을 한다.Conventionally, as shown in FIG. 3, since the X adjusting nut 11 is formed in a trapezoidal shape, the Y adjusting nut 12 is rotated left and right to move the A / C head support plate 13 up and down in the direction of the arrow. While adjusting Y axis.
이때 A/C 헤드 지지판(13)이 A,A'등의 위치로 변하게 되고 이에 따라 Y축 조정포인트가 앞쪽으로 이동하여 Y축 조정점이 A에서 A'로 이동하면서 X의 값이 "T"만큼 변하게 되므로 X 조정너트(11)를 회전시켜 A/C 헤드 지지판(13)의 위치를 A'에서 A에 위치하도록 하여 X축 조정 포인트를 맞추어야만 했으므로 A/C 헤드의 조정때마다 X축과 Y축을 일일이 조정하여야 하는 번거로움이 생기고 Y축이 조정 상태에서 X축을 조정하거나 X축이 조정된 상태에서 Y축을 조정한 후에 다시 조정 오차에 대한 위치 변경이 따라야 하는 불편이 있었다.At this time, the A / C head support plate 13 changes to the position of A, A 'and so on, and the Y-axis adjustment point moves forward, so that the Y-axis adjustment point moves from A to A' and the value of X is "T". Since the X adjustment nut 11 was rotated so that the position of the A / C head support plate 13 was positioned from A 'to A, the X axis adjustment point had to be aligned. It was inconvenient to adjust the axis one by one, and to adjust the X axis while the Y axis was adjusted, or to adjust the Y axis while the X axis was adjusted, and then to change the position of the adjustment error again.
이와 같은 단점을 보완하기 위한 본 고안은 A/C 헤드 지지판과 맞닿아 X축 조정을 하는 X 조정 너트를 직면체로 형성하고 A/C 헤드 고정축에 끼워져 A/C 헤드 지지판을 탄성으로 받쳐주는 코일 스프링의 일측을 연장하여 X 조정 너트 고정측에 감아 X 조정 너트가 탄성으로 수직 승강하도록 하여 Y축 조정시에도 X축의 위치 변동이 없도록 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention to compensate for this disadvantage is to form an X adjustment nut for the X-axis adjustment in contact with the A / C head support plate as a face and fitted to the A / C head fixed shaft to support the A / C head support plate elastically One side of the spring is wound around the X adjustment nut fixing side so that the X adjustment nut is vertically elevated by elasticity so that the position of the X axis does not change even when the Y axis is adjusted.
VTR에 있어서, 테이프가 타고 가는 상태에서 오디오 신호를 콘트롤하는 A/C 헤드(1)의 하단에 스크류(1-1)로 고정된 A/C 헤드 지지판(2)의 일측은 로딩 플레이트(3)에 고정된 A/C 헤드 고정축(4-1)에 끼워져 Y 조정 너트(4)를 회전시키면서 상하로 조정하도록 하고, 타측은 로딩 플레이트(3)에 X 조정 너트 고정축(5-1)이 고정된 직면체형 X 조정 너트(5)에 맞닿게 하며, A/C 헤드 고정축(4-1)에 감긴 스프링(6)의 일측을 연장하여 X 조정 너트 고정축(5-1)에도 감아 X 조정 너트(5)에 탄성을 주도록 한 것이다.In the VTR, one side of the A / C head support plate 2 fixed with a screw 1-1 on the lower end of the A / C head 1 that controls the audio signal while the tape is riding is the loading plate 3. Is inserted into the A / C head fixing shaft 4-1 fixed to the Y / Y head while the Y adjustment nut 4 is rotated up and down, and the other side of the loading plate 3 has the X adjustment nut fixing shaft 5-1 Abuts the fixed face type X adjustment nut (5), extends one side of the spring (6) wound around the A / C head fixing shaft (4-1), and also winds the X adjustment nut fixing shaft (5-1) The adjustment nut 5 is elasticized.
미설명 부호 7은 테이프이다.Reference numeral 7 is a tape.
이와 같은 본 고안은 제 2 도에 도시된 바와 같이 A/C 헤드(1)를 조정할때 Y축을 Y 조정너트(4)를 회전시켜 A/C 헤드 지지판(2)을 화살표 방향으로 이동시키면서 Y축을 조정하면 A/C 헤드 지지판(2)의 위치가 X 조정너트(5)에 A 또는 A'의 상태가 된다.The present invention, as shown in FIG. 2, rotates the Y adjustment nut 4 in the Y axis when the A / C head 1 is adjusted, while moving the A / C head support plate 2 in the direction of the arrow. If it adjusts, the position of the A / C head support plate 2 will be in the state of A or A 'with the X adjustment nut 5.
X축의 조정 포인트가 A위치이었다면 A/C 헤드 지지판(2)의 위치가 A'로 바뀐다 하더라도 X축 조정 포인트는 항상 일정하게 된다.If the adjustment point of the X axis is the A position, the X axis adjustment point is always constant even if the position of the A / C head support plate 2 changes to A '.
따라서 X축 조정 포인트를 한번 조정하면 Y축 조정을 하더라도 X 조정은 다시할 필요가 없고 스프링(6)은 A/C헤드 지지판(2)을 상측으로 밀면서 전방으로 밀어 주는 한편 X 조정 너트(5)를 상측으로 밀어 주고 있으므로 외력에도 X 조정 포인트는 변하지 않는 것이다.Therefore, once the X-axis adjustment point is adjusted, even if Y-axis is adjusted, X adjustment is not necessary again and the spring 6 pushes the A / C head support plate 2 upward and pushes it forward while the X adjustment nut (5) Is pushing upwards, so the X adjustment point does not change even with external force.
이와 같이 X 조정 너트(5)를 직면체로 형성하고 스프링의 일측을 연장하여 상측으로 탄성을 받도록 함으로써 X축 조정 포인트가 변하지 않도록 한 것이다.As such, the X adjustment nut 5 is formed as a facing body, and one side of the spring is extended to receive the elasticity upward, so that the X axis adjustment point does not change.
