본 발명은 자기기록 및 재생기의 릴 구동장치에 관한 것으로, 특히 캡스탄(capstan)에서 카세트 구동릴(reel)로 동력을 전달할 때 필요하였던 마찰클러치를 개략함으로써 사용부품수를 절감하고 릴의 높이를 축소하도록 한 릴 구동장치에 관한 것이다.The present invention relates to a reel driving device of a magnetic recording and reproducing apparatus. In particular, the friction clutch required when transferring power from a capstan to a cassette driving reel reduces the number of parts used and increases the height of the reel. It relates to a reel drive device to be reduced.
종래 브이씨알(VCT : Video cassette tape recorder)과 디에이티(DAT : digital audio tape recorder)와 같은 자기기록 및 재생기는 제1도에 도시한 바와같이 캡스탄(1)의 동력으로 릴(3)을 구동시킬 때 타이밍 벨트(2)를 이용하여 동력을 전달한다.Conventional magnetic recorders and players, such as VCT (Video cassette tape recorder) and DAT (Digital Audio Tape Recorder), use the power of the capstan (1) as shown in FIG. When driven, power is transmitted using the timing belt 2.
공급릴(3)와 권취릴(3)의 사이에는 아이들러 기구(4)가 설치되어 양측 릴(3)을 선택적으로 구동시키도록 되어있으며, 아이들러 기구(4)는 입력 아이들러 기구(5)의 출력 아이들러 기구(5)의 축(5')을 중심으로 회전하는 레버의 단부에 축착되어 있으나 레버의 도시는 생략되어 있다.An idler mechanism 4 is provided between the supply reel 3 and the take-up reel 3 to selectively drive both reels 3, and the idler mechanism 4 outputs the input idler mechanism 5. Although it is affixed to the end of the lever which rotates about the axis 5 'of the idler mechanism 5, illustration of the lever is abbreviate | omitted.
제2도는 릴(3)의 상세 단면도로서 이에 도시한 바와 같이, 베이스플레이트에 고정되는 축에 축착되는 상하부디스크(7), (8)의 사이에 펠트(9)가 삽입되고, 하부디스크(8)의 하부에는 압력조절스프링(10)의 설치되어 있다.2 is a detailed cross-sectional view of the reel 3, as shown therein, a felt 9 is inserted between the upper and lower disks 7 and 8, which are fixed to the shaft fixed to the base plate, and the lower disk 8 At the bottom of the), a pressure regulating spring 10 is installed.
종래의 장치는 캡스탄(1)에 발생한 일정한 회전력이 타이밍 벨트(2)를 통해 아이들어 기구(4)의 입력 아이들러 기구(5)에 전달되고 캡스탄(1)의 회전방향에 따라 출력 아이들러 기어(6)가 공급릴(3) 또는 권취릴(3)에 밀착하게 되어 동력을 전달한다.In the conventional apparatus, the constant rotational force generated in the capstan 1 is transmitted to the input idler mechanism 5 of the idler mechanism 4 through the timing belt 2 and the output idler gear in accordance with the rotation direction of the capstan 1. 6 is in close contact with the supply reel (3) or winding reel (3) to transmit power.
종래의 데크(deck)에서는 테이프 주행시 캡스탄(1)의 일정한 회전으로 인하여 테이프의 잔량에 따라 회전편차가 발생하므로 이것을 해결하기 위하여 릴(2)에 상, 하부 디스크(7), (8), 펠트(9) 및 압력조절 스프링(10)등으로 된 마찰클러치 기구를 설치하여 펠트(9)를 통해 동력을 전달하고 여분의 회전력은 펠트(9)와 하부디스크(8) 사이의 미끄럼에 의하여 단절되게 하거나, 또는 캡스탄(1)과 아이들러 기구(4)에서 마찰 클러치를 이용하여 미끄럼을 유발시키도록 되어있다.In the conventional deck (deck) due to the constant rotation of the capstan (1) when running the tape rotation deviation occurs depending on the remaining amount of the tape, so to solve this, the upper, lower disks (7), (8), A friction clutch mechanism, such as a felt 9 and a pressure regulating spring 10, is installed to transfer power through the felt 9 and the extra rotational force is disconnected by sliding between the felt 9 and the lower disk 8. Or by using a friction clutch in the capstan 1 and the idler mechanism 4 to induce slippage.
그러나 상기한 바와 같은 종래의 장치는 상, 하부 디스크(7), (8), 펠트(9) 및 압력조절 스프링(10)등 사용부품수가 많고 구조가 복잡하기 때문에 조립성이 저하될 뿐 아니라 소형, 경량화에 많은 불리한 결함이 있었다.However, the conventional apparatus as described above has a large number of parts and complicated structure such as upper, lower disks (7), (8), felts (9), and pressure regulating springs (10). There were many disadvantageous defects in weight reduction.
본 발명은 상기한 바와 같은 종래의 결함을 해소하기 위하여 릴 구동용 아이들러 기구의 입력 아이들러 기어와 캡스탄을 일정한 회전 토오크 이상에서 슬립이 발생하는 슬림벨트로 연결하여 필요한 슬립이 유발되도록 함으로써 복잡한 마찰 클러치를 제거할 수 있도록 한 것인 바, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention provides a complex friction clutch by connecting the input idler gear and the capstan of the reel drive idler mechanism to a slim belt that generates slip above a certain rotational torque in order to solve the above-mentioned defects. It will be to remove the bar, which will be described in detail by the accompanying drawings as follows.
제3도는 본 발명에 의한 릴 구동장치의 평면도로서, 이에 도시한 바와 같이 캡스탄(1)의 전방부에 공급릴(3)과 권취릴(3)이 설치되고, 공급릴(3)과 권취릴(3) 사이에는 아이들러 기구(4)가 설치된 것에 있어서, 캡스탄(1)의 풀리(1a)와 입력 아이들러 기구(5)의 풀리(5a)를 일정한 부하 이상에서 슬립이 일어나도록 슬립벨트 텐션조절수단(15)을 설치하여서 된 것이며, 슬립벨트(11)로 연결하고, 슬립벨트(11)의 일측에는 슬립벨트 텐션조절수단(15)은 슬립벨트(11)의 일측에 텐션조절레버(12)의 일단부를 축(12')으로 축착하여 그 타단부에 고정된 접촉핀(13)을 슬립벨트(11) 외면에 접촉시키고, 텐션조절레버(12)의 중간부에는 접촉핀(13)을 탄력으로 접촉시키기 위한 스프링(14)을 연결하여서 된 것이다. 상기 슬립벨트(11)는 펠트(felt)로 제작하는 것이 바람직하나 이에 한정되는 것은 아니다.3 is a plan view of a reel drive device according to the present invention, and as shown therein, a supply reel 3 and a winding reel 3 are provided at the front of the capstan 1, and a supply reel 3 and a winding are provided. When the idler mechanism 4 is provided between the reels 3, the slip belt tension so that slippage occurs between the pulley 1a of the capstan 1 and the pulley 5a of the input idler mechanism 5 above a certain load. It is made by installing the adjustment means 15, connected to the slip belt 11, one side of the slip belt 11, the tension belt tension adjusting means 15 is a tension control lever 12 on one side of the slip belt (11) ) And the contact pin 13 fixed at the other end thereof to the outer surface of the slip belt 11 and the contact pin 13 at the middle of the tension control lever 12. It is made by connecting the spring 14 for elastic contact. The slip belt 11 is preferably made of felt, but is not limited thereto.
이와같이된 본 발명은 캡스탄(1)에서 동력이 발생하면 펠트재 슬립벨트(11)를 통해 아이들러 기구(4)의 입력 아이들러 기어(5)에 전달되고, 출력 아이들러 기어(6)에 의하여 공급릴(3) 또는 권취릴(3)이 구동되며, 이와같이 동력이 전달되는 과정에서 필요한 만큼의 미끄럼이 캡스탄(1)과 슬립벨트(11) 사이에서 슬립벨트(11)와 입력 아이들러 기어(5) 사이에서 발생하게 된다.When the power is generated in the capstan 1, the present invention is transmitted to the input idler gear 5 of the idler mechanism 4 through the felt material slip belt 11, and is supplied by the output idler gear 6. (3) or the take-up reel (3) is driven, the slip as necessary in the process of transmitting power is the slip belt 11 and the input idler gear (5) between the capstan (1) and the slip belt (11). Will occur in between.
텐션조절수단(15)은 슬립벨트(11)와 캡스탄(1) 또는 입력 아이들러 기어(5) 사이에 과도한 미끄럼이 발생하지 않도록 하기 위한 것으로, 텐션 필요이상으로 느슨해지면서 스프링(14)의 탄성력이 작용하여 텐션조절레버(12)가 슬립벨트(11)의 장력을 강하게 하는 방향으로 회동시키게 되며 텐션이 필요이상으로 강하게 되면 슬립벨트(1)가 텐션조절레버(12)를 반대방향으로 회동시켜 장력을 감소시킨다.The tension adjusting means 15 is for preventing excessive slippage between the slip belt 11 and the capstan 1 or the input idler gear 5, and the elastic force of the spring 14 is loosened while the tension is loosened more than necessary. When the tension control lever 12 rotates in the direction in which the tension of the slip belt 11 is increased, the tension belt is rotated in the opposite direction when the tension becomes stronger than necessary, and the tension control lever 12 rotates in the opposite direction. Decreases.
또한 상기 텐션조절수단(15)의 텐션조절레버(12) 일측에는 텐션조절레버 이동수단(16)을 설치하여 FF(정방향 빨리감기)나 REW(역방향 빨리감기)시에 텐션조절레버 이동수단(16)에 의하여 텐션조절레버(12)를 강제로 이동시켜 필요한 강한 장력을 얻을 수 있다.In addition, a tension control lever moving means 16 is installed at one side of the tension control lever 12 of the tension control means 15 so that the tension control lever moving means 16 at the time of FF (forward fast forward) or REW (reverse fast forward). By forcibly moving the tension control lever 12 can obtain the necessary strong tension.
상기한 텐션조절수단(15)은 일정한 장력을 유지할 뿐 아니라, 조립시에도 이점을 준다. 즉 조립시 충분한 느슨한 슬립벨트(11)를 끼우고 텐션조절레버(12)에 장가하며 수축성이 약한 벨트도 조립이 용이하기 때문이다.The tension adjusting means (15) not only maintains a constant tension, but also provides an advantage during assembly. That is, because the assembly is easy to assemble a belt with a loose shrink belt 11, the tension control lever 12, and the weak shrinkage during assembly.
이상에 설명한 바와 같이 본 발명은 릴에 마찰클러치를 사용할 필요가 없다. 따라서 마찰클러치에서 필요한 여러 가지 부품을 절약할 수 있고, 이에따라 릴의 높이를 대폭 축소할 수 있으며, 릴의 경·박·단·소형와에 기여하는 이점이 있다.As described above, the present invention does not require the use of a friction clutch on the reel. Therefore, it is possible to save various parts necessary for the friction clutch, and accordingly, the height of the reel can be greatly reduced, which contributes to the thin, thin, short, and small size of the reel.
