본 고안은 VTR의 공급리일 및 감김리일을 회전시키는 아이들러의 장치에 관한 것으로 특히 모드(Mode)전환이 신속하게 이루어질 수 있도록 하기 위하여 공급측 아이들러기어와 감김측 아이들러 기어를 각각 설치하고 테이프 주행의 안정을 위해 클러치장치를 아이들러에 설치한 VTR의 아이들러 장치에 관한 것이다.The present invention relates to an idler device for rotating a feed rail and a winding rail of a VTR. In particular, a feed side idler gear and a winding side idler gear are respectively installed in order to enable a quick mode change, and the tape running is stable. For an idler device of a VTR with a clutch device mounted on the idler.

종래에는 아이들러기어를 하나만 설치하였기 때문에 모드전환시간이 길어져서 화면이 일그러지는 경향이 있었고 테이프에 과부하가 걸릴때 슬립이 발생하도록 하여 테이프 및 기기의 손상을 방지하기 위한 클러치장치를 리일디스크에 직접설치하기 때문에 리일디스크의 정도를 저하시켜 테이프 재생시 테이프의 흔들림을 주는 등 제품의 성능을 저하시킨다는 문제점이 제기되었다.Conventionally, because only one idler gear is installed, the mode switching time is long, so the screen tends to be distorted, and slippage occurs when the tape is overloaded so that the clutch device is installed directly on the real disk to prevent damage to the tape and the device. Therefore, the problem of lowering the performance of the product, such as lowering the degree of the real disk to give a tape shake when playing the tape has been raised.

본 고안은 이러한 문제점을 해결하기 위하여 공급 및 감김릴 디스크를 각각 구동시키기 위한 분기형 아이들러 장치를 형성하는 동시에 상기 아이들러장치에 클러치장치를 설치하므로써 모드의 전환시간을 단축하고 테이프주행에 안정성을 부여하고자 하는데 목적이 있다.In order to solve this problem, the present invention is to form a branched idler device for driving the feeding and reeling disks respectively, and at the same time to install a clutch device in the idler device to shorten the mode switching time and to provide stability to tape driving. The purpose is to.

본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

본 고안의 구성은 제1도에 도시된 바와 같이 아이들러아암(5)을 분기형으로 성형하여 공급리일디스크(3)와 감김리일디스크(4)를 각각 구동시키기 위한 두개의 아이들러기어(1)(2)를 축핀(1a)에 의하여 고정시키고 상기 아이들러아암(5)은 좌우 회전이 가능한 상태로 메인기어축핀(8)을 이용하여 브라켓(6)에 고정한후 캡스턴모터(도시안됨)의 회전방향에 따라 공급축 또는 감김축 리일디스크를 구동시시키도록 하고 테이프에 과부하가 작용하는 경우 동력을 차단하는 클러치작용이 아이들러부에서 가능하도록 제2도에 도시된 바와 같이 메인기어스프링(9), 메인기어플레이트(10), 메인기어펠트(11), 폴리(12)를 순차적으로 조립한 다음 플레인와셔(13)와 E-링(14)을 이용하여 고정시키고 상기 부품이 조립된 브라켓(6)은 스크류(6a)에 의해 본체데크에 고정시킴으로써 이루어진다.The configuration of the present invention is two idler gears (1) for driving the supply rail disk (3) and the winding rail disk (4) by molding the idler arm (5) in a branched shape as shown in FIG. (2) is fixed by the shaft pin (1a) and the idler arm (5) is fixed to the bracket (6) using the main gear shaft pin (8) in a state that can rotate left and right, the rotation direction of the capstan motor (not shown) According to the main gear spring (9), main as shown in FIG. 2 to enable the drive shaft or the winding shaft disc to drive the drive and the clutch action to cut off the power when the tape is overloaded The gear plate 10, the main gear felt 11 and the pulley 12 are sequentially assembled, and then fixed using the plane washer 13 and the E-ring 14, and the bracket 6 to which the parts are assembled is By fixing to the body deck by screw (6a) Achieved.

상기한 바와 같이 구성된 본 고안의 작용효과는 다음과 같다.Effects of the present invention configured as described above are as follows.

제1도에 도시된 바와 같이 실선으로 표시된 것을 공급측 아이들러기어(1)가 공급측리일디스크(3)에 동력을 전달하는 상태를 나타내는 것으로 테이프되감기(RW), 동작상태이며 여기서 테이프의 재생이나 녹화 또는 빨리 보내기(FF)로 모드전환시에는 감김측 리일디스크(4)가 회전해야 하므로 제1도의 가상선부처럼 아이들러 아암(5)이 메인기어축핀(8)을 중심으로 회전이동하여 감김아이들러기어(2)가 감김리일디스크(4)와 밀착되어 동력이 전달된다.As shown in FIG. 1, the solid line indicates the state in which the supply-side idler gear 1 transmits power to the supply-side rail disc 3, which is a tape rewinding (RW) operation state, in which a tape is played or recorded. When the mode is switched to fast forward (FF), the winding side disc (4) should rotate, so the idler arm (5) rotates around the main gear shaft pin (8) like the imaginary line of FIG. ) Is in close contact with the winding rail disk 4, the power is transmitted.

상기 동작에서 공급측 아이들러기어(1)와 감김측 아이들러기어(2)가 각기 역할분담을 하여 모드전환시 아이들러아암(5)의 회전동작 각도가 작아져서 그만큼 빨리 모드전환시간이 단축되는 효과를 얻어 화면의 일그러짐을 방지할 수 있다.In the above operation, the supply side idler gear 1 and the winding side idler gear 2 share their roles so that the rotational operation angle of the idler arm 5 becomes smaller when the mode is switched, thereby achieving an effect of shortening the mode switching time. Distortion can be prevented.

한편 공급측 리일디스크가 회전하지 않아 테이프에 과부하가 걸릴 경우에도 로딩모터나 캡스턴모터로 부터의 동력은 밸트(15)를 계속 전달되므로 이때 동력을 차단하기 위해 아이들러부에 클러치장치를 설치하여 테이프 및 기기를 보호하므로서 종래의 리일디스크에 설치되었던 클러치 장치로 인한 리일 디스크의 마모로 테이프가 흔들리는증의 제품성능저하요인을 제거하였다.On the other hand, even if the supply side disc does not rotate and the tape is overloaded, the power from the loading motor or the capstan motor is continuously transmitted to the belt 15. At this time, a clutch device is installed on the idler to cut off the power. As a result, the degradation of the product performance of the tape shake caused by the wear of the rail disc due to the clutch device installed in the conventional rail disc was eliminated.
