본 고안은 캡스턴과 릴의 구동을 캡스턴 모터의 동력이나 캡스턴 구동부의 동력을 벨트로 연결하여 상호 구동하도록 한 VTR에 있어서, 메인 데크에 고정한 받침판에 장공이 스크류로 고정되어 힌지를 중심으로 회전하도록 된 회전판의 일측에 아이들 풀리(Idle pully)를 회전자재하도록 축삽하여 회전판을 회전시키면서 안내풀리에 끼워진 동력 전달용 캡스턴 벨트를 밀어주거나하며 텐션을 조절할 수 있도록 한 VTR의 캡스턴 벨트 텐션 조절 장치에 관한 것이다.The present invention is a VTR in which the driving of the capstan and the reel is driven by connecting the power of the capstan motor or the power of the capstan driving unit with a belt, the long hole is fixed with a screw to the support plate fixed to the main deck to rotate around the hinge The present invention relates to a capstan belt tension adjusting device of a VTR, which is configured to insert an idle pully on one side of a rotating plate to rotate a rotating plate while pushing a power transmission capstan belt fitted to a guide pulley and adjusting tension.
종래에는 VTR의 캡스턴과 릴의 구동을 캡스턴 모터나 캡스턴 구동부의 동력을 연결하여 상호 구동케함으로써 각 모우드에 따른 캡스턴의 회전수를 결정하는데 기구적인 벨트의 장력 상태가 미끄러짐이나 마모 그리고 벨트의 자체산포에 의해 상당한 영향을 끼친다.Conventionally, the capstan and reel of the VTR are driven by connecting the power of the capstan motor or the capstan drive unit to determine the number of rotations of the capstan according to the respective modes. Has a significant impact on
그러므로 벨트의 정확한 장력 유지가 되지 않음으로 인해 특정 모우드에서 모터의 구동력을 정확히 전달할 수 없음은 물론 경시 변화에 의한 미끄러짐과 이물등에 의한 벨트의 훼손등으로 VTR의 구동계에 큰 영향을 주게 되는 문제점이 있었다.Therefore, it is not possible to accurately transmit the driving force of the motor in a specific mode due to the inability to maintain the tension of the belt, and there is a problem that greatly affects the drive system of the VTR due to slippage due to changes over time and damage to the belt due to foreign objects. .
이와 같은 종래의 단점을 보완하기 위한 본 고안은 메인데크에 고정한 받침판에 장공이 스크류로 고정되어 스크류를 푼 상태에서 힌지를 중심으로 회전할 수 있도록 된 회전판의 일측에 아이들 풀리를 회전자재하도록 축삽하여 회전판을 회전시키면서 안내풀리에 끼워진 캡스턴 벨트를 밀어주거나 원 상태로 환원시키며 미끄러짐이나 훼손에도 상관 없이 일정한 장력 유지가 되도록 한 것으로 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention to compensate for the disadvantages of the prior art by inserting the idle pulley on the side of the rotating plate to be rotated about the hinge in the state in which the long hole is fixed to the support plate fixed to the main deck with a screw to rotate While rotating the rotating plate to push the capstan belt inserted into the guide pulley or to the original state and to maintain a constant tension regardless of slip or damage as described in detail by the accompanying drawings as follows.
VTR에 있어 메인데크(1)에 고정 스크류(2)로 고정한 받침판(3)에 장공(4-1)이 스크류(5)로 고정되어 스크류(5)를 푼 상태에서 손잡이(4-2)를 잡고 힌지(4-3)를 중심으로 회전시키도록 된 회전판(4)의 일측에 아이들 풀리(6)를 축(4-4)으로 회전 자재하게 축삽하여, 캡스턴 플라이 휠(7)의 풀리(7-1)와 릴 풀리(8)를 상호구동시키는 캡스턴 벨트(9)를 안내홈(6-1)에 끼운 상태에서 밀어 주거나 원 상태로 환원시키도록 한 것이다.In the VTR, the long hole 4-1 is fixed to the support plate 3 secured to the main deck 1 with the fixing screw 2, and the handle 4-2 is removed while the screw 5 is loosened. The pulley 6 of the capstan flywheel 7 by inserting the idle pulley 6 into the shaft 4-4 on one side of the rotating plate 4 to be rotated about the hinge 4-3. -1) and push the capstan belt (9) for driving the reel pulley (8) in the guide groove (6-1) in the state of being pushed or reduced to the original state.
이와 같은 본 고안은 캡스턴 모터나 구동부의 동력을 캡스턴 플라이 휠(7)의 풀리(7-1)와 릴 풀리(8)를 캡스턴 벨트(9)로 연결하여 상호 구동하도록 한 상태에서 미끄럼짐이나 훼손등으로 캡스턴 벨트(9)의 장력이 약할때에는 받침판(3)의 윗면에 나사조임한 스크류(5)를 풀고 직각으로 벤딩된 손잡이(4-2)를 이용하여 회전판(4)를 힌지(4-3)를 중심으로 회전시켜 제 3 도의 점선으로 도시된 것과 같이 알맞은 각도를 이동시킨 후 장공(4-1)에 삽입된 스크류(5)를 조여 회전판(4)을 받침판(3)에 고정하면, 회전판(4)의 회전에 따라 이의 일측에 축(4-4)으로 회전자재하도록 축삽된 아이들 풀리(6)도 점선의 위치로 이동하면서 안내홈(6-1)에 끼워진 캡스턴 벨트(9)를 밀어주어 장력이 커지도록 하여 캡스턴 벨트(9)가 항상 일정한 장력이 유지되도록 한 것이다.The present invention, such as the capstan motor or the driving unit by the power of the capstan flywheel (7) and the pulley (7-1) and the reel pulley (8) by the capstan belt (9) to drive each other to slip or damage When the capstan belt 9 is weakly tensioned by the back, loosen the screw 5 screwed on the upper surface of the support plate 3 and hinge the rotary plate 4 by using the handle 4-2 bent at a right angle (4-). 3) by rotating the center of rotation around the appropriate angle as shown by the dashed line in Figure 3 and then tighten the screw (5) inserted in the long hole (4-1) to fix the rotating plate 4 to the backing plate (3), As the rotor plate 4 rotates, the idle pulley 6 inserted to rotate on one side thereof with the shaft 4-4 moves to the position of the dotted line, and the capstan belt 9 fitted in the guide groove 6-1 is moved. By pushing the tension to increase the capstan belt (9) is to maintain a constant tension at all times.
반대로 캡스턴 벨트(9)의 장력이 너무 셀 경우에는 장공(4-1)에 삽입된 스크류(5)를 풀고 회전판(4)을 힌지(4-3)를 중심으로 반대 방향으로 일정각도 회전시킨 후 스크류(5)를 나사 조임하여 회전판(4)을 받침판(3)에 고정하면 아이들 풀리(6)도 따라서 이동하면서 이의 안내홈(6-1)에 끼워진 캡스턴 벨트(9)가 밀리던 상태에서 어느 정도 해제되며 장력도 약해지게되는 것이다.On the contrary, if the tension of the capstan belt 9 is too high, loosen the screw 5 inserted in the long hole 4-1 and rotate the rotating plate 4 at an angle about the hinge 4-3 in the opposite direction. When the screw (5) is screwed to fix the rotating plate (4) to the support plate (3), the idle pulley (6) also moves along, while the capstan belt (9) fitted in its guide groove (6-1) is pushed. The degree is released and the tension is weakened.
이와 같이 메인데크(1)에 고정한 받침판(3)에 스크류(5)로 장공(4-1)이 끼워진채 나사조임되어 힌지(4-3)를 중심으로 회전하는 회전판(4)의 일측에 아이들 풀리(6)를 축(4-4)으로 회전자재하게 축삽하여 이의 안내홈(6-1)에 끼워진 캡스턴 벨트(9)를 밀어주거나 원 상태로 환원시키면서 캡스턴 풀리(7-1)와 릴 풀리(8)를 상호 구동시키는 캡스턴 밸트(9)의 장력이 항상 일정하게 되도록 임의로 조절할 수 있도록 한 것이다.In this way, the support plate 3 fixed to the main deck 1 is screwed with the long hole 4-1 inserted into the support plate 3 fixed to the main deck 1, and idled on one side of the rotating plate 4 rotating about the hinge 4-3. Capstan pulley (7-1) and reel pulley while rotating pulley (6) rotatably with shaft (4-4) to push or reduce the capstan belt (9) fitted in the guide groove (6-1) thereof. It is to be able to arbitrarily adjust the tension of the capstan belt (9) for driving (8) is always constant.
