제2도는 종래 고안의 설치 상태도.2 is an installation state of the conventional design.
* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
4 : 지지대 5 : 핀치롤러4: support 5: pinch roller
7 : 핀 8 : 회동레버7: pin 8: pivot lever
9 : 플레이 아이들러9: play idler
본 고안은 캡스턴 모우터의 벨트 구동 방식을 가지는 VTR에 있어서, 감개릴을 구동시키는 플레이 아이들러 작동계를 단순화시키면서 보다 확실한 회전력을 종동축에 전달시키기 위하여 안출된 것이다.The present invention is designed to transfer a more reliable rotational force to a driven shaft while simplifying the play idler operating system for driving a reel in a VTR having a belt driving method of a capstan motor.
종래의 플레이 아이들러 개폐 장치를 보면 도면 제2도에서와 같이, 캡스턴 모우터(도시하지 않음)의 회전력을 벨트로써 캡스턴 휠(1')과 이에 압입된 캡스턴 축(2')에 전달하면, 캠기어(도시하지 않음)에 의해 핀치롤러(도시하지 않음)가 캡스턴 축(2')과 접촉 회전하면서 테이프를 이송시키고 이와 동시에 캠기어가 푸쉬레버(10)의 잠김동작을 해제시켜 플레이 아이들러(9')가 캡스턴 휠(1')과 감개릴(3')사이에 접촉하여 감개릴(3')을 회전시키므로써 이송된 테이프를 감아주도록 되어 있다.In the conventional play idler opening and closing device, as shown in FIG. 2, when the rotational force of the capstan motor (not shown) is transmitted to the capstan wheel 1 'and the capstan shaft 2' press-fitted thereto as a belt, the cam A pinch roller (not shown) is moved by the gear (not shown) in contact with the capstan shaft 2 'to transfer the tape, and at the same time, the cam gear releases the locking action of the push lever 10 so that the play idler 9 Is wound between the capstan wheel 1 'and the reel 3' to rotate the reel 3 'to wind the conveyed tape.
그러나, 이와 같은 것은 플레이 아이들러(9')와 핀치롤러가 서로 다른 링크에 연결 설치되어 있어 캡기어가 핀치롤러와 푸쉬레버(10)를 2중동작 해야만 이들이 동시에 구동되도록 되어 있기 때문에 작동계가 복잡하여 이들의 제작 및 연결 설치가 복잡하고 보다 많은 설치 공간을 요구하게 되고 자칫하면 오동작이 발생하여 제품의 신뢰도를 저하시키는 등의 결점이 있었다.However, this type of operation system is complicated because the play idler 9 'and the pinch roller are connected to different links so that the cap gear is operated by the dual operation of the pinch roller and the push lever 10. The manufacturing and connection installation of these is complicated and requires more installation space, and there is a drawback that a malfunction occurs and the reliability of the product is lowered.
따라서, 본 고안은 종래의 위와 같은 결점을 해결하기 위하여 핀치롤러의 지지대 임의 지점에 핀으로써 플레이 아이들러를 가진 회동레버를 결합 설치하므로써, 핀치롤러를 제어하는 캠기어의 한동작으로 함께 아이들러가 감개릴과 캡스턴 휠 사이에 접촉 또는 분리될 수 있도록 한 것으로 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Therefore, the present invention is coupled to the rotation lever having a play idler by pinning at any point of the support of the pinch roller in order to solve the above drawbacks of the prior art, the idler is wound together by one operation of the cam gear to control the pinch roller. And it can be contacted or separated between the capstan wheel as described in detail by the accompanying drawings as follows.
즉, 도면 제1도에서와 같이 선단에 핀치롤러(5)를 설치한 지지대(4)를 캠기어(도시하지 않음)로써 회전시켜 캡스턴 축(2)에 접촉 분리 동작시키는 통상의 것에 있어서, 지지대(4)의 일측에 핀(7)으로써 회동레버(8)의 후단부를 고정 설치하여 이를 중심으로 회동할 수 있도록 한뒤, 회동레버(8)의 선단부에 플레이 아이들러(9)를 설치하여서 된 것으로 도면 중 미설명 부호는 1은 캡스턴 휠 3은 감개릴이다.That is, in the ordinary thing which rotates the support 4 which installed the pinch roller 5 at the front end with a cam gear (not shown) as shown in FIG. The rear end of the pivoting lever 8 is fixedly installed with a pin 7 at one side of the pivoting shaft 4 so as to be rotated around the pivoting lever, and the play idler 9 is installed at the distal end of the pivoting lever 8. Unexplained reference numeral 1 is the capstan wheel 3 is a reel.
이상과 같이 구성된 본 고안은 캠기어가 동작하여 지지대(4)를 회전시켜 핀치롤러(5)를 캡스턴 축(2)에 접촉시킬 때 회동레버(8)에 설치한 플레이 아이들러(9)도 핀(7)을 중심으로 회동하면서 캡스턴 휠(1)과 감개릴(3) 사이에 삽입되어 캡스턴 모우터에서 벨트로써 구동력을 전달받은 캡스턴 휠(1)의 회전력을 감개릴(3)에 전달하므로써, 캡스턴 축(2)과 핀치롤러(5) 사이에 이송된 테이프가 감개릴(3)에 의해 감기도록 한 것이다.The present invention constructed as described above has the play idler 9 installed on the pivoting lever 8 when the cam gear is operated to rotate the support 4 to contact the pinch roller 5 to the capstan shaft 2. 7) the capstan wheel (1) is inserted between the capstan wheel (1) and the reel (3) while rotating about the center, and transmits the rotational force of the capstan wheel (1) to which the driving force is transmitted from the capstan motor to the coil (3). The tape conveyed between the shaft 2 and the pinch roller 5 is wound by the reel reel 3.
또 지지대(4)를 역회전시켜 핀치롤러(5)를 캡스턴 축(2)에서 분리 시킴과 동시 플레이 아이들러(9)도 캡스턴 휠(1)과 감개릴(3) 사이에서 분리되도록 하였다.In addition, the support 4 was reversed to separate the pinch roller 5 from the capstan shaft 2, and the simultaneous play idler 9 was also separated between the capstan wheel 1 and the reel 3.
이상과 같이 상호 유기적인 연관 작용을 하는 핀치롤러(5)와 플레이 아이들러(9)를 지지대(4)에 함께 설치하여 필요시 동시 작동케 하므로써, 종래의 2원화 되어 있던 작동 장치를 1원화시키면서 푸쉬버레버 및 이의 연관 작동 장치를 제어하게 되어 부품의 감소로 인한 제작 및 설치상의 난점을 해결하고 기구적 메카니즘의 단순화로 오동작이 발생할 염려가 없으며, 제품의 소형 경량화 요구를 만족시킬 수 있는등의 효과가 있다.As described above, the pinch rollers 5 and the play idler 9 having mutually organic relations are installed together on the support 4 so that they can be operated simultaneously if necessary, thereby pushing the conventional binary device into a single unit while pushing the unit. By controlling the lever and its associated operating device, it is possible to solve the manufacturing and installation difficulties due to the reduction of parts, and there is no fear of malfunction due to the simplification of the mechanical mechanism, and it can satisfy the small size and light weight requirement of the product. There is.
