본 고안은 브이씨알의 릴 및 캡스탄 소프트 브레이크 장치에 관한 것으로, 특히 권취릴 소프트 브레이크와 캡스탄 소프트 브레이크를 연동구조로 형성한 릴 및 캡스탄 소프트 브레이트 장치에 관한 것이다.The present invention relates to a V reel and capstan soft brake device, and more particularly, to a reel and capstan soft brake device formed by interlocking a winding reel soft cap and a capstan soft brake.
종래에는 제1도에 도시한 바와같이, 공급릴(1)과 권취릴(2)의 하측에서 좌우로 직선이동하는 평션플레이트(3)의 작동핀(3a)이 캠기어(4)의 캠홈(4a)에 삼입되고, 캠기어(4)의 외주면에 형성된 기어부에는 구동모터(5)의 웜(6)이 맞물리게 되어 있으며, 캡스탄 휠(7)의 일측에는 솔레노이드(8)로 작동되어 그를 제동하는 캡스탄 브레이크(9)가 설치되고, 권취릴(2)의 일측에는 그를 제동하는 릴 브레이크(10)가 메인베이스에 고정되는 측(11)에 회전가능하게 설치되며, 그의 하면에 고정된 핀(10a)이 평선플레이트(3)의 장공(3a′)에 삽입되어 있다.Conventionally, as shown in FIG. 1, the actuating pins 3a of the flat plate 3 linearly moving from the lower side of the supply reel 1 and the take-up reel 2 to the left and right of the cam groove 4 of the cam gear 4 The worm 6 of the driving motor 5 is engaged with the gear part formed on the outer circumferential surface of the cam gear 4, and is engaged with the solenoid 8 on one side of the capstan wheel 7. A capstan brake 9 for braking is installed, and one side of the take-up reel 2 is rotatably installed at a side 11 fixed to the main base, and a reel brake 10 for braking it is fixed to its lower surface. The pin 10a is inserted into the long hole 3a 'of the flat plate 3.
도면에서 12는 캡스탄 측을 보인것이고, 13은 회전헤드르럼을 보인것이며, 14는 공급릴(1)과 권취릴(2)에서 각종 주행계 부품을 거쳐 헤드드럼(13)에 접촉되도록 장가되는 테이프를 보인 것이다.In the drawing, 12 is a capstan side, 13 is a rotating head drum, and 14 is loaded to contact the head drum 13 through various traveling parts in the supply reel 1 and the winding reel 2. I showed the tape.
상기와 같은 종래의 장치는 테이프(14)를 헤드드럼(13)주위로 인출시킬 때 테이프(14)는 공급릴(1)측에서 풀려 나가야만 재생위치를 정확하게 찾을수 있는바, 이를 위해 권취릴(2)측에 소프트 브레이크(10)를 제동시켜 여기에서 풀림량을 줄이게 한다.In the conventional apparatus as described above, when the tape 14 is pulled out around the head drum 13, the tape 14 must be released from the supply reel 1 side to accurately find the play position. Braking the soft brake 10 on the side 2) reduces the amount of loosening there.
소프트 브레이크(10)의 착탈동작은 캠기어(4)의 회전에 따라 이에 형성된 캠홈(4a)에 작동핀(3a)이 접동되면서 평선플레이트(3)가 우측으로 이동하고 그 평선플레이트(3)의 장공(3a′)이 브레이크핀(10a)을 밀면 브레이크(10)가 헤제되는데, 테이프(14)가 드럼(13)주위로 로딩이 완료될 때 까지는 평선플레이트(3)가 이동해도 브레이크(10)가 해제되지 않고 고속되감기나 재생시에 해제되며 또한 리뷰시에 권취릴(2)에 밀착되어 테이프(14)에 적정량의 텐션을 부여하여 안전된 화면을 재생시킬 수 있게 된다.In the detachable operation of the soft brake 10, the flat plate 3 moves to the right as the actuating pin 3a is slid into the cam groove 4a formed according to the rotation of the cam gear 4. When the long hole 3a 'pushes the brake pin 10a, the brake 10 is released. Even if the flat plate 3 is moved until the tape 14 is finished loading around the drum 13, the brake 10 Is released during high-speed rewinding or replaying, and close to the winding reel (2) during review to impart an appropriate amount of tension to the tape (14), thereby reproducing a safe screen.
그리고, 슬로우 재생시나 정지화면 재생시에는 캡스탄휠(7)의 회전 관성력이 발생하여 적정위치에서 캡스탄이 정지하지 못하여 화면의 상부가 불안정한 상태로 될 수 있으므로 이를 방지하기 위해서 캡스탄휠(7)의 관성력을 제거하도록 별도의 캡스탄 브레이크99)가 설치되고 이를 작동시키기 위한 솔레노이드(8)가 별도의 회로적 제어에 의하여 작동되도록 하고 있는 것이다.In addition, in the case of slow playback or still image playback, the rotational inertia force of the capstan wheel 7 is generated, and the capstan wheel 7 may be unstable because the capstan may not stop at an appropriate position. A separate capstan brake 99 is installed to remove the inertial force of the solenoid 8 so as to operate it by separate circuit control.
그러나, 종래에는 테이프(14)를 드럼(13)주위로 로딩 시킬 때 브레이크 제동력과 리뷰시 테이프 텐션을 부여하기 위한 브레이크 제동력이 동일 브레이크에 의한 것이므로 브레이크력이 동일하게 발생하게 된다. 따라서, 각각의 모드에서 필요한 적정 제동력이 아니어서 작동에 다소 결함이 있을 수 있고 별도의 캡스탄 브레이크(9)제동을 위한 솔레노이드(8) 등을 사용하므로 부품수 및 원가적 측면에서 불리하며, 또한 브레이크턱이 동일하여 로딩시 테이프 풀림량이 많아서 재생위치를 찾기가 곤란한 문제점등이 있었다.However, in the related art, when the tape 14 is loaded around the drum 13, the brake braking force and the brake braking force for giving the tape tension at the time of review are caused by the same brake, so that the brake force is generated the same. Therefore, it is not proper braking force required in each mode, so it may be somewhat defective in operation, and a separate capstan brake 9 uses a solenoid 8 for braking, which is disadvantageous in terms of parts and cost. Since the brake jaws were the same, there was a problem that it was difficult to find a play position because the amount of tape unwinding was large during loading.
본 고안은 이와같은 종래의 장치에 따른 문제점을 해소하기 위하여 안출한 것으로 이를 첨부한 도면 제1도 내지 제5도에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve the problems according to the conventional apparatus, which will be described in detail with reference to FIGS. 1 to 5 as follows.
제2도는 본 고안 장치의 구성을 보인 정지상태의 평면도이고 제3도는 통상의 부분 확대도이며 제5도는 본 고안의 작동기구 설명도로서, 이에 도시한 바와같이, 캡스탄 휠(7)의 일측에 캡스탄 브레이크(15)를 축핀(16)으로 축착하고, 권취릴(2)의 일축에 권취릴 브레이크(17)를 축핀(18)으로 축착함과 아울러 캡스탄 브레이크(15)의 일축 돌기(15a)와 권취릴 브레이크(17)의 중간 돌부(17a)간에 인장스프링(19)을 연결하고, 상기 캡스탄 브레이크(15)의 하면에는 단차(15b)(15c)(15d)를 가지는 캠형상 단차부(15e)를 형성하고 상기 평선플레이트(3)에는 상기 캡스탄 브레이크(15)의 단차부(15e)에 접동되는 접동핀(3b)를 고정하여서 된 것으로, 도면에서 미설명 부호 17b는 권취를 브레이크(17)의 중간부에 고정된 핀이고, 3c는 그 핀(17b)이 삽입되도록 평선플레이트(3)에 형성된 장공을 보인 것이다.2 is a plan view of a stationary state showing the configuration of the device of the present invention, and FIG. 3 is a partial enlarged view of a conventional part, and FIG. 5 is an explanatory view of the operation mechanism of the present invention, as shown therein, one side of the capstan wheel 7 The capstan brake 15 is fixed with the shaft pin 16, the winding reel brake 17 is fixed with the shaft pin 18 on one axis of the winding reel 2, and the uniaxial projection of the capstan brake 15 ( A cam-shaped step having a step (15b) (15c) and (15d) is connected to the tension spring (19) between the middle protrusion (17a) of the winding reel brake (17a) and the capstan brake (15). It is formed by fixing the sliding pin (3b) to form a portion (15e) and the step plate (15e) of the capstan brake 15 to the flat plate (3), reference numeral 17b in the drawing The pin is fixed to the middle of the brake 17, 3c is a long hole formed in the flat plate 3 so that the pin 17b is inserted Will be shown.
이와같이된 본 고안은 제2도와 같은 정지상태에서 카세트에서 테이프를 인출하여 드럼(13)주위로 로딩시키기 전까지 캠(4)의 회전에 의해서 평성플레이트(3)가 이동함에 따라 접동핀(3b)이 함께 이동하면서 캡스탄 브레이크(15)의 캠 단차부(15e)를 밀게 된다. 이때 제5도와 같이 핀(3b)이 * S 만틈 이동하면 캡스탄 브레이크(15)가 축점 양측부의 거리비 11: 12에 의하여 축(16)을 기준으로 회전하면서 스프링 고정점에 * X만큼의 편위차가 발생하여 스프링(19)에 K. * X만큼의 장력이 증가되어 (K는 비례상수), 축(18)을 기준으로 회동하는 권취릴 브레이크(17)의 제동력이 * fr만큼 증가하게 되고 권취릴(2)을 증가된 제동력으로 제동하므로 권취릴(2)측에서 테이프(14) 풀림량을 극소화시킬 수 있게 된다.In this way, the sliding pin 3b is moved as the flat plate 3 is moved by the rotation of the cam 4 until the tape is removed from the cassette and loaded around the drum 13 in the stationary state as shown in FIG. While moving together, the cam step 15e of the capstan brake 15 is pushed. At this time, as shown in FIG. 5, when the pin 3b moves only * S, the capstan brake 15 rotates about the axis 16 by the distance ratio 1 1 : 1 2 of both sides of the axis point, And the tension of K. * X is increased in spring 19 (K is proportionality), and the braking force of winding reel brake 17 which rotates about axis 18 is increased by * f r . And the braking reel (2) by the increased braking force is to be able to minimize the amount of loosening the tape 14 on the take-up reel (2) side.
또한 캠(4)의 회전에 의하여 평션플레이트(3)가 더 이동하여 고속 되감기 모드에 이르면 접동핀(3b)이 캡스탄 브레이크(15)의 단차(15c)에 도달하고 이때에는 캡스탄 브레이크(15)가 스프링(19)에 의해 캡스탄 휠(7)측으로 약간 밀리게 되므로 권취릴 브레이크(17)의 제동력이 저하되어 권취릴(2)의 회전 토오크가 증가되므로 릴의 관성에 의하여 테이프(14)의 불균일 감김 등을 방지할 수 있으며, 재생모드시에는 평선플레이트(3)의 장공(3c)이 권취릴 브레이크(17)의 핀(17b)을 밀어 그 권취릴 브레이크(17)가 권취릴(2)에서 이탈되어 구동계의 부하를 최소화한 상태로 구동되게 한다.In addition, when the motion plate 3 moves further by the rotation of the cam 4 to reach the high speed rewind mode, the sliding pin 3b reaches the step 15c of the capstan brake 15, and at this time, the capstan brake 15 ) Is slightly pushed toward the capstan wheel 7 by the spring 19, so that the braking force of the take-up reel brake 17 is lowered and the rotational torque of the take-up reel 2 is increased. Uneven winding and the like can be prevented. In the regeneration mode, the long hole 3c of the flat plate 3 pushes the pin 17b of the winding reel brake 17, and the winding reel brake 17 is wound up. ) To be driven with minimal load on the drive system.
또한, 스틸이나 슬로우 재생시에는 제4도와 같이, 평선플레이트(3)의 접동편(3b)이 캡스탄 브레이크(15)의 최저 단자(15d)에 위치하여 캡스탄 브레이크(15)의 브레이크 수가 캡스탄 휠(7)에 밀착되고 스프링(19)의 장력이 캡스탄 휠(7)의 제동력으로 작동되어 스틸이나 슬로우 재생시 캡스탄 휠(7)의 관성에 의한 회전을 방지하여 정상적인 화면을 얻을 수 있게 된다.In the case of still or slow regeneration, the sliding piece 3b of the flat plate 3 is positioned at the lowest terminal 15d of the capstan brake 15 as shown in FIG. 4, so that the number of brakes of the capstan brake 15 is capstan. It is in close contact with the wheel 7 and the tension of the spring 19 is operated by the braking force of the capstan wheel 7 to prevent the rotation of the capstan wheel 7 by the inertia during steel or slow regeneration to obtain a normal screen. do.
