본 고안은 브이 씨 알에 적용되는 캡스턴모터의 회전 불균일 보정장치에 관한 것으로 특히 일련의 기어와 브래키트로 이루어지는 기어 조립체를 스프링과 솔레노이드를 이용하여 캡스턴 휘일에 밀착 또는 유격되도록하여 캡스턴 모터의 회전불균일로 인한 진동으로 발생되는 와우/플러터(Wow and Flutter)를 방지할수 있게한 캡스턴 모터의 회전 불균일 보정 장치에 관한 것이다.The present invention relates to a device for compensating the rotational nonuniformity of a capstan motor applied to a V seed, and in particular, a gear assembly consisting of a series of gears and a bracket is made to be in close contact or play with the capstan wheel by using springs and solenoids. The present invention relates to a device for compensating rotational unevenness of a capstan motor, which can prevent wow and flutter caused by vibration caused by the vibration.

일반적으로 브이 씨 알에 적용되는 캡스턴 모터는 핀치로울러와 압착되어 테이프를 이송시키는 캡스턴축과 캡스턴 모터에 회전관성을 부여하는 캡스턴 휘일이 일체를 이루고 있는 구조로서 캡스턴 모터가 회전시 발생되는 모터자체의 기계적 진동이나 오차를 보정하기 위한 별도의 수단을 구비하고 있지 않다.In general, the capstan motor applied to the V seed is a structure in which the capstan shaft for compressing the pinch roller and conveying the tape and the capstan wheel for imparting rotational inertia to the capstan motor are integrally formed. No additional means for compensating for mechanical vibrations or errors is provided.

따라서 캡스턴모터가 회전시 전원의 노이즈나 회로적인 발진노이즈등에 의하여 회전불균일 현상이 발생되고, 이는 오디오 파형의 떨림 즉, 와우/풀러터를 발생시키는 주요인이 되어 왔다.Therefore, the rotation non-uniformity occurs due to the noise of the power source or the circuit oscillation noise when the capstan motor rotates, which has been the main cause of the vibration of the audio waveform, that is, the wow / fullerter.

본 고안은 종래의 이와 같은 문제점을 해소하기 위하여 안출한 것으로 캡스턴 모터에서 발생되는 회전 불균일 및 발진현상을 방지하여 와우/ 풀러터를 최소화할 수 있는 장치를 제공함과 아울러 캡스턴 휘일의 회전력을 이용하여 팬을 회전시킴으로써 데크내부의 발생열을 냉각시켜 주는 장치를 제공하는데 그 목적이 있는 것인바 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a problem in the related art, and provides a device that can minimize the wow / fullerter by preventing rotation unevenness and oscillation occurring in the capstan motor, and using a rotational force of the capstan wheel. It is an object of the present invention to provide a device for cooling the heat generated inside the deck by rotating it described in detail by the accompanying drawings as follows.

제1도 및 제2도에 도시한 바와 같이 캡스턴 휘일(1)의 일측 인접부위에 중간부가 핀축(2)으로 유착되고 선단부에 걸림돌기(3a)가 구비되는 작동레버(3)를 축설하여 그 하측단부를 기판상에 착설한 솔레노이드(4)의 작동봉(4a)에 연결하고, 상기 작동레버(3)의 상부에는 일측단부가 기판상에 고정된 인장스프링(5)과 연결되어 상기 플라이 휘일(1)측으로 회전력을 가지는 브래키트(4)를 동심축상에 축설하는 한편, 상기 브래키트(6)의 하면에는 하측에 소기어(7a)가 일체로 형성되는 마찰차(7)를 제1축(8)으로 축설하고, 그 제1축(8)의 일측에는 소기어(9a)를 일체로 가지는 중간기어(9)를 제2축(10)으로 축설하여 그 소기어(9a)가 상기 마찰차(7)의 소기어(7a)와 맞물리게 함과 아울러 그 제2축(10)의 일측에는 중간부에 기어부(11a)가 형성되고 단부에 팬(12)이 부착되는 제3축(11)을 축설하여 기어부(11a)가 상기 중간기어(9)와 맞물리게 한 것으로, 도면중 미설명 부호1'는 캡스턴 모터를 보인 것이다.As shown in FIG. 1 and FIG. 2, the operating lever 3 which has the intermediate part adhered to the pin shaft 2 at one adjacent part of the capstan wheel 1, and the locking projection 3a is provided in the front end is constructed, and The lower end is connected to the actuating rod 4a of the solenoid 4 mounted on the substrate, and the upper end of the actuating lever 3 is connected to the tension spring 5 fixed at the substrate to the flywheel. While the bracket 4 having the rotational force on the (1) side is laid out on the concentric axis, the friction difference 7 in which the small gear 7a is integrally formed on the lower surface of the bracket 6 is formed on the first shaft. And the intermediate gear 9 having the small gear 9a integrally formed on the one side of the first shaft 8 by the second shaft 10, and the small gear 9a is subjected to the friction. The third shaft is engaged with the small gear 7a of the vehicle 7 and the gear portion 11a is formed at an intermediate portion at one side of the second shaft 10 and the fan 12 is attached at the end portion thereof. 11) is arranged so that the gear portion 11a is engaged with the intermediate gear 9, and reference numeral 1 'in the figure shows a capstan motor.

이와 같이 구성되는 본 고안의 작용효과를 상세히 설명하면 다음과 같다.If described in detail the effect of the present invention is configured as follows.

솔레노이드(4)에 전원이 인가되지 않은 상태에서 브래키트(6)는 인장스프링(5)의 탄성을 받아 캡스턴 휘일(1)측으로 힘을 받게 되므로 브래키트(4)의 하측에 설치된 마찰차(7)는 캡스턴 휘일(1)과 압착되는 상태가 되고, 캡스턴 휘일(1)이 1-3회전 /초의 정속회전을 하게되면 그 회전력은 이와 압착하고 있는 마찰차(7)를 통하여 소기어(7a), 중간기어(9)의 소기어(9a), 그리고 중간기어(9)와 제3축(11)의 기어부(11a)에 전달되면서 각기어의 치차비에 의한 가속상태가 되는 것이다.In the state where power is not applied to the solenoid 4, the bracket 6 receives the elasticity of the tension spring 5 and is forced to the capstan wheel 1 side, so that the friction difference 7 ) Is in a state of being pressed against the capstan wheel (1), when the capstan wheel (1) has a constant speed rotation of 1-3 revolutions / second, the rotational force of the small gear (7a) through the friction difference (7) The small gear 9a of the intermediate gear 9 and the gear 11a of the intermediate gear 9 and the third shaft 11 are accelerated by the gear ratio of each gear.

이를 다시 구체적으로 설명하면, 정상가능 수행시 캡스턴 모터(1')가 구동되어 캡스턴 휘일(1)이 회전을 하게되면 솔레노이드(4)에는 전원이 인가되지 않는 상태가 되고, 이와 같은 상태에서 인장스프링(5)의 힘을 받은 브래키트(6)가 핀축(2)을 중심으로 회전하게 되므로 캡스턴 휘일(1)과 마찰차(7)가 밀착되어 캡스턴 휘일(91)의 회전력이 마찰차(7)에 전달되고, 그 회전력에 의하여 마찰차(7)의 소기어(7a)가 회전하면서 중간기어(9)의 소기어(9a)을 회전시키며 이는 다시 중간기어(9)를 통하여 제3축(11)에 전달되어 팬(12)을 회전시키게 된다.In detail, when the capstan motor 1 'is driven and the capstan wheel 1 rotates during normal operation, the solenoid 4 is not powered, and the tension spring is in this state. Since the bracket 6 subjected to the force of (5) rotates around the pin shaft 2, the capstan wheel 1 and the friction wheel 7 are brought into close contact with each other so that the rotational force of the capstan wheel 91 is reduced by the friction wheel 7. The small gear 7a of the friction wheel 7 rotates while the small gear 9a of the intermediate gear 9 is rotated by the rotational force, which in turn rotates the third shaft 11 through the intermediate gear 9. ) To rotate the fan 12.

이와 같이 캡스턴 휘일(1)의 회전력이 마찰차(7)를 통하여 각 기어(7a)(9)(9a)(11a)에 전달되고 이들의 치차비에 의하여 배속되면서 캡스턴 모터(1')에서 발생되는 기계적 오차에 의한 진동이나 회전 불균일, 그리고 회로적인 노이즈에 의한 발진등이 감쇄되고 최종적으로 팬(12)이 회전시 받게되는 공기 저항에 의하여 완전히 감쇄가 되어 캡스턴 모터(1')의 원활한 회전이 이루어지는 것이다.In this way, the rotational force of the capstan wheel 1 is transmitted to the respective gears 7a, 9, 9a, 11a through the friction wheel 7, and is generated in the capstan motor 1 'while being doubled by the gear ratio. Vibration due to mechanical error, rotational unevenness, and oscillation due to circuit noise are attenuated and finally attenuated by air resistance received when the fan 12 rotates, thereby smoothly rotating the capstan motor 1 '. It is done.

한편, 캡스턴 모터(1')가 정상속도의 수배로 고속 회전을 하게 되는 FF/REW등의 모드 수행시에는 캡스턴모터(1')에 무리한 토오크를 주게 되므로 이때에는 캡스턴 휘일(1)로부터 마찰차(7)를 유격시켜야 한다.On the other hand, when the capstan motor 1 'performs a mode such as FF / REW that rotates at a high speed several times the normal speed, excessive torque is given to the capstan motor 1'. At this time, the friction difference from the capstan wheel 1 (7) is to be freed.

따라서 제1도의 가상선으로 도시한 바와 같이 솔레노이드(4)에 전원이 인가되어 작동봉(4a)이 화살표방향으로 이동을 하게되고, 이에 따라 작동레버(3)가 핀축(2)을 중심으로 시계방향의 회전을 하여 그 단부의 걸림돌기(3a)가 브래키트(6)을 시계방향으로 회전시켜 주므로 캡스턴 휘일(1)과 마찰차(7)는 유격되는 상태가 되어 캡스턴 모터(1')의 고속주행에 영향을 주지 않게 되는 것이다.Therefore, as shown by the imaginary line of FIG. 1, power is applied to the solenoid 4 so that the operating rod 4a moves in the direction of the arrow. Thus, the operating lever 3 is clocked around the pin shaft 2. Direction, and the locking projection 3a at the end rotates the bracket 6 clockwise, so that the capstan wheel 1 and the friction wheel 7 are in a state of being spaced apart, so that the capstan motor 1 ' It does not affect high speed driving.

이상에서 상술한 바와 같이 본 고안은 캡스턴 모터(1')의 회전 불균일 현상이 마찰차 (7)를 통하여 각 기어(7a)(9)(9a)(11a)에 전달되면서 감쇄되고 또한 팬(12)을 회전하게 하여 그 팬(12)의 회전시 발생되는 공기저항에 의하여 완전히 감쇄가 되므로 와우/풀러터를 최소화할 수 있음은 물론 데크 내부의 냉각효과도 아울러 갖게되는 효과가 있다.As described above, the present invention is attenuated while the rotational nonuniformity of the capstan motor 1 'is transmitted to each of the gears 7a, 9, 9a, and 11a through the friction difference 7, and the fan 12 By rotating the fan is completely attenuated by the air resistance generated during the rotation of the fan 12 can minimize the cochlea / puller as well as have the effect of cooling the inside of the deck as well.
