본 고안은 기판의 저면 일측에 기히 설치되어 있는 캡스턴모우터에서 동력을 전달받아 그 회동속도를 필요에 따라 저속 또는 고속으로 변속하여 아이들러를 구동시켜 아이들러가 감김 및 공급릴 디스크에 접촉하므로서 이들을 구동시키기위한 별도의 모우터를 필요로하지 않아 부품수 감소로 인한 제품의 소형화 경량화와 제작비 절감은 물론 제작이 간편하도록 한 비디오 테이프 레코더의 릴 디스크 구동장치에 관한 것이다.The present invention receives power from the capstan motor, which is installed on one side of the bottom surface of the substrate, and shifts the rotational speed to a low speed or a high speed as necessary to drive the idler to drive them by contacting the winding and feeding reel disks. The present invention relates to a reel disk driving device of a video tape recorder, which is easy to manufacture, as well as lighter and lighter product due to the reduction of the number of parts due to the need for a separate motor.
종래의 릴 디스크 구동장치를 보면 감김과 공급릴 디스크 하방에 각각 FF나 REW시에 필요한 고속모우터와 그리고 play시에 필요한 아이들러 구동용 기어모우터를 각각 설치하여 필요에 따라 별도의 스위치 장치로서 이들을 구동시켜 왔는데, 이는 각각의 구동체 회동축마다 별도의 모우터를 설치해야하므로서 이에 따른 설치면적이 커져 그 몸체의 부피가 커지면서 무게가 무겁고 부품수 증가로 인한 제작비 상승은 물론 설치작업에 많은 시간과 인력은 낭비해야 하는 결점이 있었다.In the conventional reel disc drive device, a high speed motor required for FF and REW and an idler drive gear motor for play, respectively, are installed below the winding and supply reel discs, respectively. It has been driven, which requires a separate motor to be installed for each drive shaft, so the installation area is increased, and the volume of the body increases, the weight is heavy, and the production cost increases due to the increase in the number of parts, as well as a lot of time for installation work. The workforce had a drawback to be wasted.
따라서 본 고안은 종래의 위와같은 결점을 해결하기 위하여 안출한 것으로 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to solve the above drawbacks as described above in detail by the accompanying drawings as follows.
즉 기판(1)상 양측에 공급릴디스크(2)와 감김릴디스크(3)를 설치하고 그 사이에 아이들러(4)를 설치하며 후방저면에 캡스턴모우터(5)를 설치한 통상의 것에 있어서, 기판(1)의 전방부 양측에 안내봉(6)을 각각 돌출설치하고 그 사이에 작동공(7)을 형성하며 저면에 고정대(11)를 밀착시키고 그 측방에 고정축(12)을 하향돌출 시킨다음, 양측에 안내공(9)과 중앙에 요부(10)를 형성한 슬라이드판(8)의 안내공(9)을 안내봉(6)에 끼운뒤, 상부에 부쉬(14)를 형성한 회동축(13)을 부쉬(14)가 기판(1)상으로 돌출되도록 고정대(11)에 유동설치하여 그 하부에 구동기어(15)를 압입한, 선단에 작동간(17)을 형성하고 중앙부에 돌출봉(18)을 상향돌출 형성한 포오크레버(16)후단부를 고정대(11)일측에 유동설치하되 돌출봉(18)이 기판(1)의 작동공(7)으로 돌출하여 슬라이드판(8)의 측면에 밀착토록 하고 고정축(12)이 작동간(17)사이에 위치토록한 다음 고정축(12)에는 양측에 핀(20)을 돌출형성한 링체(19)와 그 하방에 클러치부(22)를 하향돌출 형성하고 구동기어(15)와 치합되는 변속기어(21)그리고 수개의 삽입편(25)을 형성한 마찰구(24) 및 중앙부에 클러치부(28)을 상향돌출 형성한 풀리(27)를 차례로 유동설치하되 변속기어(21)와 마찰구(24)사이에 펠트(23)를 설치하여 일측면을 변속기어(21)에 접착시키고 삽입편(25)으로 연결된 마찰구(24)와 풀리(27)사이에 스프링(26)을 탄설하면 양측 클러치부(22)(18)는 마찰구(24)내에서 일정간격을 떨어져 위치토록 한후 풀리(27)와 캡스턴 모우터(5)사이에 벨트(30)를 설치하여서된 것으로 도면중 미설명부호 29는 고정링이다.In other words, in the usual case in which the supply reel disk 2 and the reel reel disk 3 are installed on both sides of the substrate 1, the idler 4 is installed therebetween, and the capstan motor 5 is installed on the rear bottom. Guide protrusions 6 are respectively provided on both sides of the front part of the substrate 1, and the operation holes 7 are formed therebetween, and the fixing stand 11 is brought into close contact with the bottom thereof, and the fixing shaft 12 is lowered on the side thereof. After protruding, the guide hole 9 of the slide plate 8 having the guide hole 9 on both sides and the recessed portion 10 in the center is inserted into the guide rod 6, and then the bush 14 is formed on the upper side. One rotation shaft 13 is flow-installed on the holder 11 so that the bush 14 protrudes onto the substrate 1, and the operating shaft 17 is formed at the tip end of which the drive gear 15 is press-fitted therein. The rear end portion of the fork lever 16, which protrudes upwardly from the protruding bar 18, is installed on one side of the fixing stand 11, but the protruding bar 18 protrudes into the operating hole 7 of the substrate 1, thereby providing a slide plate ( 8) on the side of Closely contact with each other, and the fixed shaft 12 is positioned between the operation sections 17. Then, the fixed shaft 12 has the ring body 19 protruding the pins 20 on both sides thereof, and the clutch portion 22 below. A friction gear 24 having a downwardly protruding formation and a transmission gear 21 engaged with the drive gear 15 and several insertion pieces 25, and a pulley 27 having the clutch portion 28 upwardly protrudingly formed at the center thereof. And install the felt 23 between the transmission gear 21 and the friction hole 24 in order to adhere one side to the transmission gear 21 and to the friction hole 24 and the pulley connected by the insertion piece 25. When the spring 26 is installed between the 27, the clutches 22 and 18 of the two sides are spaced apart by a predetermined distance in the friction hole 24, and then the belt between the pulley 27 and the capstan motor 5 Reference numeral 29 in the drawing indicates a fixed ring.
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 회동이 요구되는 play동작시에는 슬라이드(8)을 우측으로 당기면 스프링(26)의 탄발력으로 슬라이드판(8)측면에 밀착되었던 포오크레버(16)의 돌출봉(18)이 요부(10)내로 이동하여 그 작동간(17)이 도면 제4a도와 같이 되어 캡스턴모우터(5)에서 벨트(30)로서 전담반은 고속의 회전력은 풀리(27)와 마찰구(24)에만 전달되어 마찰구(24)와 펠트(23)사이에 슬립현상을 일으키면서 공회전하는데, 스프링(26)의 탄발력으로 마찰구(24)와 펠트(23) 사이에 마찰력이 발생하여 변속기어(21)에 저속의 동력이 전달되며 이와 치합된 구동기어(15)를 저속회전시켜 회동축(13)상부의 부쉬(14)에 밀착된 아이들러(4)를 회동시키므로서 감김릴 디스크(3)를 회동시키도록 하였고, FF나 REW와 같이 릴 디스크(2)(3)에 고속이 요구될때는 슬라이드판(8)을 좌측으로 밀면 요부(10)내에 위치하고 있던 돌출봉(18)이 도면 제4도(b)와 같이 슬라이드판(8)의 측면에 얹혀 포오크레버(16)가 하방으로 회동하면서 그 작동간(17)이 링체(19)의 핀(20)을 밀어내려 변속기어(21)도 함께 밀리면서 클러치부(22)가 풀리(27)의 클러치부(28)와 결합되어(제4도(b)참조)풀리(28)의 고속회전력이 막바로 변속기어(21)를 거쳐 구동기어(15)를 통해 아이들러(4)에 전달되므로서 릴디스크(2)(3)를 빠른 속도로 회동시킬수 있도록한 것이다.At the time of the play operation requiring slow rotational quiet rotation of the reeling disk 3, when the slide 8 is pulled to the right, the fork lever 16, which is in close contact with the side of the slide plate 8 by the spring force of the spring 26, is protruded. The rod 18 is moved into the recess 10, and the operation 17 is as shown in FIG. 4A, and as the belt 30 in the capstan motor 5, the task force of the high speed rotational force is the pulley 27 and the friction ball. It is transmitted only to the (24) and the idle rotation while causing a slip phenomenon between the friction sphere 24 and the felt 23, the friction force between the friction sphere 24 and the felt 23 is generated by the elastic force of the spring 26 Low speed power is transmitted to the transmission gear 21, and the drive gear 15 coupled thereto is rotated at low speed to rotate the idler 4 closely attached to the bush 14 on the upper rotation shaft 13, thereby rotating the reel disk ( 3) is rotated. When high speed is required for the reel disk (2) (3) such as FF or REW, slide plate (8) to the left When pushed in, the protruding rod 18 located in the recessed portion 10 is placed on the side of the slide plate 8 as shown in FIG. 4 (b), and the operating lever 17 is rotated while the fork lever 16 rotates downward. As the pin 20 of the ring body 19 is pushed down and the transmission gear 21 is pushed together, the clutch 22 is engaged with the clutch 28 of the pulley 27 (see FIG. 4 (b)). The high speed rotational force of 28 is transmitted to the idler 4 through the drive gear 15 through the transmission gear 21 so that the reel disks 2 and 3 can be rotated at high speed.
이와같이 동작하는 본 고안은 릴디스크(2)(3) 및 아이들러(4)의 구동력은 기히 설치되어 사용하고 있는 통상의 캡스턴 모우터(5)에서 전달받아 자체에서 저속, 고속으로 변속 전달토록 하여 종래 아이들러(4) 및 릴디스크(2)(3)에 각각 설치하던 별개의 모우터를 제거하므로서 그 설치면적이 작아져 제품의 소형 경량화와 부품수 감소로 인한 제작비 절감은 물론 제작에 필요한 인력과 시간의 낭비를 최대한 절감할수 있는 효과가 있다.The present invention operates as described above, the driving force of the reel disk (2) (3) and the idler (4) is transmitted from a conventional capstan motor (5), which is already installed and used, so as to shift the transmission at low speed and high speed by itself. By eliminating the separate motors installed on the idler (4) and reel disk (2) (3), the installation area becomes smaller, which reduces the production cost due to the compact size and light weight of the product, as well as the manpower and time required for production. There is an effect that can reduce the waste of the maximum.
