본 고안은 브이티알(V.T.R: video Tape Recoder)의 테이프 텐션조절 및 종진동 감쇠장치에 관한 것으로, 특히 텐션암의 텐션핀에 감쇠로울러를 축착하여 일체화 함으로써 텐션암의 작동에 의하여 테이프의 텐센 조절기능과 종진동 감쇠기능이 겸하여 달성될 수 있게한 테이프 텐션 조절 및 종진동 감쇠장치에 관한 것이다.The present invention relates to a tape tension control and longitudinal vibration damping device of VTR (Video Tape Recoder). In particular, the tension tension control function of the tape is controlled by operating the tension arm by integrating a damping roller onto the tension pin of the tension arm. The present invention relates to a tape tension control and a longitudinal vibration damping device that can be achieved in combination with a longitudinal vibration damping function.
종래에 사용되는 테이프 텐션조절 및 종진동 감쇠장치는 제1도 및 제2도에 도시한 바와같이 기기본체의 베이스 플레이트에 착설된 공급릴 테이블(1)의 일측에 텐션핀(2)을 후단부에 입설한 텐션암(3)을 축핀(4)으로 축착하여 그 선단부에는 괘지편(5)에 일단이 고정된 코일스프링(6)의 타단을 고정하고 그 중간부에는 공급릴 테이블(1)에 중간부가 감기고 일단이 고정편(7)에 고정된 텐션밴드(8)의 타탄을 고정하고 그 중간부에는 공급릴 테이블(1)에 중간부가 감기고 일단이 고정편(7)에 고정된 텐션밴드(8)의 타탄을 고정하는 한편, 텐션암(3)에 인접되는 부위에 샤프트(9)를 입설시키고, 그 샤프트(9)에 종진동 감쇠용 로울러(10)를 삽입하여 샤프트(9) 상단부에 고정된 이탈방지편(11)과 하측부에 삽입되어 코일스프링(12)으로 상향지탄되는 탄지편(13)의 사이에 가이드되어 회전되게 한 구조로 되어있다.In the conventional tape tension control and longitudinal vibration damping device, as shown in FIGS. 1 and 2, the rear end of the tension pin 2 is provided on one side of the supply reel table 1 mounted on the base plate of the main body of the apparatus. The tension arm 3 installed in the shaft is fixed to the shaft pin 4, and the other end of the coil spring 6 having one end fixed to the hanging piece 5 is fixed to the tip end thereof. The middle part is wound and the tartan of the tension band 8 fixed at one end is fixed to the fixing piece 7, and the middle part is wound at the feeding reel table 1 and the one end is fixed to the fixing piece 7 at the middle part thereof. While the tartan of 8) is fixed, a shaft 9 is placed in a portion adjacent to the tension arm 3, a longitudinal vibration damping roller 10 is inserted into the shaft 9, and an upper end of the shaft 9 is provided. Between the fixed release prevention piece (11) and the tungsten piece (13) inserted into the lower portion and supported by the coil spring 12 upward It is to be de-rotated and is a structure.
이러한 종래기술은 플레이등의 모우드가 진행되는 경우에 공급릴 테이블(1)위에 안착된 테이프 카세트(도시되지 않음)의 공급릴에서 공급되는 테이프(14)가 주행중 텐션이 강하게 되면 테이프(14)에 접촉하고 있는 텐션핀(2)이 밀리게되어 텐션암(3)의 축핀(4)을 중심으로 하여 시계방향으로 약간 회전하게 되어 공급릴 테이블(1)과 텐션밴드 사이의 마찰력이 감소되도록 작용하며, 따라서 테이프(14)가 공급릴 테이블(1) 측으로부터 쉽게 풀려나오게 되므로 테이프(14)의 텐션이 감소된다. 반대로 테이프(14)의 텐션이 약하게 되면 텐션암(3)의 코일스프링(6)의 힘에 의하여 반시계방향으로 회동하게 되고 따라서 텐션암(3)에 연결되어 있는 텐션밴드(8)가 공급릴테이블(1) 을 조이는 방향으로 이동하여 공급릴(1)과 텐션밴드(8)사이 에는 브레이크력이 크게되어 카세트로부터테이프(14)가 쉽게 풀려 나올수 있게 된다.This prior art is a tape 14, which is supplied from the supply reel of the tape cassette (not shown) seated on the supply reel table (1) in the case of a play or the like proceeds to the tape (14) The tension pin (2) in contact is pushed back to rotate slightly clockwise around the shaft pin (4) of the tension arm (3) acts to reduce the friction force between the table 1 and the tension band to supply Therefore, the tension of the tape 14 is reduced because the tape 14 is easily released from the table 1 side to be fed. On the contrary, when the tension of the tape 14 becomes weak, it rotates counterclockwise by the force of the coil spring 6 of the tension arm 3, and thus the tension band 8 connected to the tension arm 3 is supplied. By moving the table 1 in the tightening direction, the brake force is increased between the supply reel 1 and the tension band 8 so that the tape 14 can be easily released from the cassette.
또한, 테이프(14)가 주행할때는 외부 충격등에 의하여 테이프(14)에 종방향의 진동이 발생하게 되는데 감쇠로울러(10)를 설치하여 테이프가 접촉주향하게 되어 있고 그 접촉마찰력에 의하여 감쇠로울러(10)가 회전하므로 종잔동이 감쇠되어진다.In addition, when the tape 14 is driven, longitudinal vibration occurs in the tape 14 due to an external impact, etc. The damping roller 10 is installed so that the tape is in contact with the damping roller 10 by the frictional force thereof. ), The longitudinal residuals are attenuated.
그러나, 이러한 종래의 장치는 테이프 주행시 테이프의 텐션을 조절하고 종진동을 감소시키기 위하여 텐션핀(2)을 갖는 텐션암(3)과 종진동 감쇠용 로울러(10')를 각각 별도로 하였을 뿐만 아니라 감쇠로울러(10)가 고정샤프트(9)에 멀치되어 있으므로 테이프의 종진동은 물론 횡진동 감쇠에 효과적인 역할을 충분히 하지 못하는 문제점이 있었다.However, this conventional apparatus not only separates the tension arm 3 having the tension pin 2 and the roller 10 'for longitudinal vibration damping separately, in order to adjust the tension of the tape and reduce the longitudinal vibration during tape driving. Since the roller 10 is far from the fixed shaft 9, there is a problem in that the longitudinal vibration of the tape does not play an effective role in damping the lateral vibration as well.
본 고안은 이와같은 종래장치의 문제점을 해소하기 위하여 텐션 조절기구와 테이프 종진동 감쇠기구를 일체화 시키어 구조를 단순화를 기하고 텐션조절과 종진동 감쇠를 효과적으로 달성할 수 있게한 것인바 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to integrate the tension control mechanism and the tape longitudinal vibration damping mechanism in order to solve the problems of the conventional device to simplify the structure and effectively achieve the tension control and longitudinal vibration damping bar attached to the accompanying drawings When described in detail as follows.
제3도 및 제4도에 도시한 바와같이, 공급릴 테이프(1)의 일측에 텐션핀(2)이 후단부에 입설되고 전방단부가 코일스프링(6)으로 탄지되는 텐션암(3)을 축핀(4)으로 축설하여 공급릴 테이블 외주면에 감긴 텐션밴드(8)와 연결한 것이어서, 상기 텐션암(3) 텐션핀(2)에 감쇠 로울러(10')를 축착하여 감쇠로울러(10')가 주행하는 테이프(14)의 내측에 적절한 탄성으로 접촉되게한 것으로, 도면중 미 설명 부호중 종래장치와 동일한 부분에는 동일부호를 사용하였다.As shown in FIGS. 3 and 4, the tension arm 3 is mounted on one side of the supply reel tape 1 with the tension pin 2 mounted on the rear end and the front end held by the coil spring 6. It is connected to the tension band (8) wound around the outer peripheral surface of the feed reel table by the shaft pin (4), the damping roller (10 ') is affixed to the tension pin (3) tension pin (2) damping roller (10') The same reference numerals are used for the same portions as those of the conventional apparatus in the reference numerals in the figure, in which the inner side of the tape 14 is moved with proper elasticity.
이와같이 된 본 고안 장치는 테이프(14)의 텐션강약에 따른 텐션조절 방식은 종래 기술과 동일하고 테이프 종진동 감쇠 기구에 있어서는 텐션암(3)의 텐션핀(2)이 테이프에 직접 접촉하게 하는 대신에 텐션핀(2)에 감쇠로울러(10')룰 설치하여 하나의 텐션암(3)으로써 텐션조절 및 종진동 감쇠 기능을 겸하여 수행할수 있을 뿐아니라, 또 종래의 방식과 다르게 감쇠로울러(10')가 고정식으로 설치되어 있지않고 텐션스프링(6)과 테이프(14)의 텐션에 따라 적절한 탄성을 가지면서 테이프(14)에 접촉되므로 테이프(14)의 종진동을 훨씬 효과적으로 감쇠시킬 수 있는 것이다.The device according to the present invention has the same tension control method according to the tension strength of the tape 14 as in the prior art, and in the tape longitudinal vibration damping mechanism, the tension pin 2 of the tension arm 3 directly contacts the tape. The attenuation roller 10 'is installed on the tension pin 2 so that the tension arm and the longitudinal vibration attenuation function can be performed as a single tension arm 3, and the damping roller 10' is different from the conventional method. ) Is not fixedly installed and is in contact with the tape 14 with appropriate elasticity according to the tension of the tension spring 6 and the tape 14 so that the longitudinal vibration of the tape 14 can be more effectively attenuated.
이상에서 설명한 바와같이 본 공란은 테이프의 텐션조절장치와 테이프의 종진동 감쇠장치를 일체화 함으로써 구조의 간소화를 도모하고, 테이프 종진동을 감쇠를 효과적으로 얻을 수 있게 되었으며, 감쇠로울러가 테이프의 신호기록면의 반대면, 즉 신호기록이 되지 않는 면과 접촉하면서 회전할 수 있게 함으로써 신호기록면의 손상을 방지하는 효과도 있다.As described above, this blank is designed to simplify the structure by integrating the tension control device of the tape and the longitudinal vibration damping device of the tape, and to effectively attenuate the tape longitudinal vibration. It is also possible to prevent damage to the signal recording surface by allowing it to rotate while being in contact with the opposite side, that is, the surface on which no signal recording is performed.
