본 고안은 비디오 테이프 레코오더(VTR)에 있어서 텐션아암과 이에 연결하는 텐션밴드의 텐션량을 세트에 따라 각기 알맞게 조절하여 테이프의 텐션이 조절되도록 한 텐션조절 장치에 대한 것이다.The present invention relates to a tension control device in which the tension of the tape is adjusted by appropriately adjusting the tension amount of the tension arm and the tension band connected thereto in the video tape recorder (VTR).
종래의 브이티알에서는 테이프이 텐션을 조절하여주기 위해 텐션아암 및 텐션포스트를 두고 리일디스크에 감겨있는 텐션밴드와 연결하여 텐션량을 조절하였으나 그 조절이 세트로 나오면 텐션량은 고정이 되고, 또한 양산시에는 모든 세트에 똑같은 스프링을 사용하게 되므로 세트마다 각기 틀린 특성을 제대로 맞추어 줄 수가 없게 되는 등의 폐단이 있었다.In the conventional VTIAL, the tension of the tape is adjusted by connecting the tension arm and the tension post to the tension band wound on the real disc to adjust the tension, but when the adjustment is released as a set, the tension is fixed and also in mass production. The same spring was used for every set, which meant that each set would not be able to match the wrong characteristics.
본 고안은 이와 같은 점들을 해결하기 위해 텐션아암에 일단을 부착하는 텐션밴드의 단부를 워엄기어의 회전에 의해 연동되는 랙에 부착시켜 워엄기어의 좌, 우 회전량에 따라 랙이 텐션밴드를 당겨주거나 늦춰주므로 각기 세트의 특성에 맞도록 텐션량을 간편 용이하게 조절하여 줄 수 있도록 고안한 것으로 첨부도면에 의거 상술하면 다음과 같다.In order to solve the above problems, the end of the tension band attaching one end to the tension arm is attached to the rack interlocked by the rotation of the worm gear, and the rack pulls the tension band according to the left and right rotation of the worm gear. It is designed to easily and easily adjust the amount of tension to suit the characteristics of each set to give or delay according to the accompanying drawings as follows.
데크에 착설하는 조절박스(1) 내의 일측에는 워엄기어(2)를 외단에 조절구(3)가 부착된 주측(4)으로 측착하고 타측에는 일단에 테션밴드(6)의 단부를 부착하는 랙(5)을 좌우이동자재토록 가이드핀(7)(7')으로 지지되게 설치하며 이들 사이에는 단일체로 성형된 대기어(8)와 소기어(9)를 축착하여 대기어(8)는 워엄기어(2)에, 소기어(9)는 랙(5)에 각각 치합되게 하고, 텐션밴드(6)의 타단은 리일디스크(10)를 거쳐 인장스프링(11)으로 탄력설치되는 텐션아암(12)의 단부에 부착시켜서된 것이다.One side in the control box (1) to be installed on the deck side of the worm gear (2) attached to the main side (4) attached to the adjuster (3) on the outer end and the other side of the rack to attach the end of the test band (6) at one end (5) is installed so as to be supported by guide pins (7) (7 ') so as to move left and right, and between them, the air gear (8) and the small gear (9) formed as a single body are compressed and the air gear (8) is warmed. To the gear 2, the small gear 9 is engaged with the rack 5, respectively, and the other end of the tension band 6 is tension arm 12 which is elastically installed to the tension spring 11 via the reel disk 10. It is attached to the end of the).
미설명 부호 "13"은 텐션폴이고 "14"는 테이프를 표시한 것이다.Reference numeral "13" denotes a tension pole and "14" denotes a tape.
이와 같이된 본 고안의 사용상태를 설명하면 다음과 같다.Referring to the state of use of the present invention as described above is as follows.
세트의 특성에 따라 텐션량을 조절해야될 때에는 조절박스(1)의 일측으로 노출된 조절구(3)를 드라이비등을 사용하여 좌측 또는 우측으로 회전시켜주면 이에 따라 주측(4)이 회전되어 워엄기어(2)가 회전되고 그 회전력은 대기어(8)와 동시에 회전되는 소기어(9)를 통해 감속되어 랙(5)에 전달되어 랙(5)을 좌, 우측으로 이동시켜 주게 된다.When it is necessary to adjust the tension amount according to the characteristics of the set, rotate the control knob 3 exposed to one side of the control box 1 to the left or the right using dry boiling, and the main side 4 is rotated accordingly. The gear 2 is rotated and its rotational force is decelerated through the small gear 9 which is rotated at the same time as the standby gear 8 and transmitted to the rack 5 to move the rack 5 left and right.
이렇게 하여 랙(5)이 제 2 도 가상선과 같이 좌측방향(L)으로 이동하게 되면 이동되는 만큼 텐션밴드(6)를 당겨주므로 리일디스크(10)와 텐션아암(12)의 텐션량을 강하게 하여주며, 반대로 랙(5)을 우측방향(R)으로 이동되게 하여주면 이번에는 이동되는 만큼 텐션밴드(6)를 풀어주게 되어 텐션량이 약하게 되는 것이다.In this way, when the rack 5 moves in the left direction L as shown in FIG. 2, the tension band 6 is pulled as much as it moves so that the amount of tension between the real disk 10 and the tension arm 12 is increased. On the contrary, if the rack 5 is moved in the right direction (R), the tension band 6 is released as much as this time, so that the amount of tension becomes weak.
이와 같이 사용하는 본 고안은 세트의 외부에서도 드라이버등으로 간편 용이하게 텐션량을 조절할 수 있게되며, 또 워엄기어의 회전력을 큰 비율로 감속시켜 랙에 전달토록 하므로 텐션량의 미세조정이 가능하게 되어 세트의 양산시 공통된 스프링을 사용하여도 텐션량을 항상 세트의 특성에 따라 각기 알맞게 조절하여 줄 수 있게 되는 효과와 또 이에 따라 성능 및 품질의 향상을 기할 수 있게 되는 등 매우 유용한 고안이다.The present invention used in this way can easily adjust the amount of tension with a driver or the like from the outside of the set, and it is possible to finely adjust the amount of tension since the rotation force of the worm gear is reduced to a large ratio and transmitted to the rack. Even when using a common spring in mass production of the set, the tension can always be adjusted appropriately according to the characteristics of the set, and accordingly the performance and quality can be improved accordingly.
