본 고안은 상부에 부쉬를 형성한 회동축 하부에 변속장치를 설치하여 기히 설치되어 있는 캡스턴 모우터에서 회전력을 전달받아 자체에서 필요에 따라 저속, 고속으로 변속시켜 그 회전력을 부쉬에 밀착 연동하는 아이들러(Idler)에 전달하므로서 별도의 모우터를 사용하지 않고서도 공급 또는 감김릴 디스크를 회동시킬 수 있도록 하므로서 부품수 감소를 인한 제품의 소형 경량화와 제작비 절감은 물론 제작이 용이하도록 한 비디오 테이프 레코더의 릴 디스크 구동장치에 관한 것이다.The present invention is provided with a transmission in the lower portion of the rotating shaft formed with a bush on the upper side receives the rotational force from the capstan motor, which is already installed, the idler shifts the rotational force to the bush in close contact with the rotational force as needed, Reel of a video tape recorder that makes it easy to manufacture, as well as to reduce the weight and manufacturing cost of the product due to the reduction of the number of parts by reducing the number of parts by allowing the rotating of discs to be supplied or wound without using a separate motor. A disk drive device.

종래의 릴 디스크 구동 장치를 보면 자체 속도 조절장치가 없기 때문에 감김릴과 공급릴 디스크의 회동축 하방 각각 FF나 REW시에 필요한 고속 모우터를 그리고 play동작시 필요한 아이들러 구동축 하방에 기어 모우터를 설치하여 필요에 따라 별도의 스위치 장치로서 어느 한쪽 모우터를 가동 이들을 구동시켜 왔는데, 이는 각각의 회동축마다 별도로 모우터를 설치하므로서 이에 따른 설치 면적이 증가하여 부피가 커지고 무게가 무거워지며 부품수 증가로 인한 제작비 상승은 물론 설치 작업에 많은 시간과 인력을 낭비해야하는 결점이 있었다.In the conventional reel disk drive system, since there is no speed control device, the high speed motor required for the FF or REW and the gear motor installed under the idler drive shaft for the play operation, respectively, below the rotating shaft of the reel and the supply reel disk. Therefore, as a separate switch device, one of the motors has been driven as needed. This is because the motors are installed separately for each rotation shaft, thereby increasing the installation area, making the volume bulky and heavy, and increasing the number of parts. There was a drawback that wasted a lot of time and manpower for installation work as well as the increase in production cost.

따라서 본 고안은 종래의 위와같은 결점을 해결하고저 구동 동력원을 일원화시킨 것으로 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Therefore, the present invention solves the above drawbacks of the prior art and unified the low drive power source as described in detail by the accompanying drawings as follows.

즉, 기판(1)의 양측에 공급릴 디스크(2)와 감김릴 디스크(3)를 설치하고 그 사이에 아이들러(4)를 설치한 통상의 것에 있어서 기판(1)의 전방 양측에 안내봉(6)과 그 사이에 통공(7)을 형성한 다음 양측방에 작동공(9)과 중앙부에 통공(10) 및 돌기(11)를 형성한 슬라이드판(8)의 양측 작동공(9)을 안내봉(6)에 끼운뒤 상부에 부쉬(13)를 형성하고 그 하부에 변속기어(14)를 압입한 회동축(12)을 부That is, in the conventional one in which the supply reel disk 2 and the reel reel disk 3 are provided on both sides of the substrate 1, and the idler 4 is provided therebetween, the guide rods are provided on both front sides of the substrate 1. 6) and the through holes 7 formed therebetween, and then the operating holes 9 on both sides and the operating holes 9 on both sides of the slide plate 8 having the through holes 10 and the projections 11 formed in the center. After inserting into the guide rod (6) to form a bush (13) in the upper portion and the rotating shaft (12) press-fit the transmission gear (14) in the lower portion

이와같이 구성된 본 고안의 작동상태를 보면 다음과 같다.Looking at the operating state of the present invention configured as described above are as follows.

먼저 감김릴 디스크(3)의 서행 정숙 운전속도가 요구되는 play시에는 버튼(도시하지 않음)을 누르면 별도의 전달장치에 의하여 슬라이드판(8)이 안내봉(6)을 따라 우측으로 이동하면서 그 통공(10)내에 위치한 레버(20)의 돌출봉(22)을 함께 이동시켜 그 후방 하단에 설치한 체인지 기어 (23)가 도면 제3도 및 도면 제4도(b)와 같이 변속기어(14)및 연동기어(15)에서 분리된다.First, when play is required for slow running speed of the reeling disk 3, pressing a button (not shown) causes the slide plate 8 to move to the right along the guide rod 6 by a separate transmission device. As shown in FIG. 3 and FIG. 4 (b), the change gear 23 which moves the protruding rod 22 of the lever 20 located in the through hole 10 and is installed at the rear lower end thereof is shifting gear 14 as shown in FIG. ) And the interlocking gear 15.

이렇게 되면 캡스턴 모우터(5)에서 빠른 회전력을 전달받은 풀리(16)와 이에 연결핀(15')으로 결합된 연동기어(15)가 동속도로 회전하게 되는데 스프링(18)의 탄력으로 펠트(17)에서 슬립현상을 일으키면서 공회전하고 이로 인해 변속기어(14)In this case, the pulley 16, which has received a quick rotational force from the capstan motor 5, and the interlocking gear 15 coupled to the connecting pin 15 'are rotated at the same speed. 17) idling, causing slippage in 17), resulting in transmission gears (14)

또한 그 작동간을 슬라이드판(8)의 돌기(11)에 밀착시킨 부레이크(25)는 슬라이드판(8)의 작동에 따라 공급릴 디스크(2)를 단속 또는 해제토록 하였다.In addition, the sub-lake 25 in which the operation is in close contact with the projection 11 of the slide plate 8 causes the supply reel disk 2 to be interrupted or released according to the operation of the slide plate 8.

이와 같이 동작하는 본 고안은 릴 디스크(2)(3)의 구동력을 기히 설치되어 사용되고 있는 통상의 캡스턴 모우터(5)에서 전달받아 자체에서 저속, 고속으로 조정하도록 하여 종래 아이들러(4) 및 릴 디스크(2)(3)에 각각 설치하던 모우터를 제거하므로서 그 설치면적이 작아져 제품의 소형 경량화와 부품수 감소로 인한 제작비 및 인력의 낭비를 최대한 절감할 수 있는 효과가 있다.The present invention operating in this way is to receive the drive force of the reel disk (2) (3) is transmitted from the conventional capstan motor (5) that is being used and used to adjust the low speed, high speed in the conventional idler (4) and reel By removing the motors respectively installed on the disks 2 and 3, the installation area is reduced, thereby minimizing the waste of manufacturing cost and manpower caused by the small size and light weight of the product and the reduction of the number of parts.
