본 고안은 테이프 레코더에 있어서, 릴어셈불리로 전달되는 아이들러의 동력을 절환시킬 수 있도록 한 아이들러 동력절환장치에 관한 것이다.The present invention relates to an idler power switching device capable of switching power of an idler transmitted to a reel assembly in a tape recorder.
일반적으로 테이프 레코더에 있어서의 아이들러는 캡스턴 모터의 회전력을 릴어셈불리로 공급 전달하는 중간 장치로서 테이프가 주행하면서 감기도록 릴어셈불리를 회전시키고 있다.In general, an idler in a tape recorder is an intermediate device that supplies and transmits the rotational force of the capstan motor to the reel assembly, and rotates the reel assembly so that the tape is wound while traveling.
그러나, 릴어셈불리에 감겨지는 테이프의 양에 따라 실제 테이프이 감기는 속도는 달라지게 된다. 따라서 이의 속도를 일정하고 정확하게 유지할 수 있는 장치가 필요하게 된다.However, the speed at which the actual tape is wound depends on the amount of tape wound on the reel assembly. Therefore, there is a need for a device that can maintain its speed constantly and accurately.
이러한 점을 감안하여 종래에는 아이들러 자체에 동력 변환을 위한 장치를 구비하고 있었으며 이는 아이들러 자체에 구비하므로서 이의 높이가 상당히 높게 되어 소형의 테이프 레코더에는 실제 이용하기 어려웠고 구조 또한 복잡하게 되어 있어 작동상의 정확 성등이 문제 되었다.In view of this, in the past, the idler itself was equipped with a device for power conversion, and since the idler itself was provided with a high height, it was difficult to use in a small tape recorder, and the structure was complicated. This became a problem.
본 고안은 상기와 같은 점을 감안하여 간단한 구조의 아이들러 동력 절환장치를 구성시킨 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in consideration of the above-mentioned configuration of an idler power switching device having a simple structure, which will be described in detail with reference to the accompanying drawings.
1은 데크로서 이의 일측에 캡스턴기어(3)를 가진 캡스턴기어(2)를 설치하고 이의 일측에 캡스턴축(4)을 설치하며 이의 하방에 릴어셈블리(5)를 설치하고 이에 아이들러(6)를 설치하며 아이들러(6)는 캡스턴모터(2)의 동력을 전달하는 벨트(7)로 구동되며 이와 같은 구성은 공지된 것이다.1 is a deck, which has a capstan gear (2) having a capstan gear (3) on one side thereof, a capstan shaft (4) on one side thereof, a reel assembly (5) underneath it, and an idler (6) thereon. The idler 6 is installed and driven by a belt 7 which transmits the power of the capstan motor 2 and such a configuration is known.
8은 캠으로서 릴어셈블리(5)의 약간 상부에 설치되고 이의 일단에 작동홈(9)이 형성되어 있다.8 is a cam provided slightly above the reel assembly 5, and one end thereof has an operating groove 9 formed therein.
10은 연결편으로 이의 일방에 상기 아이들러(6)가 설치되고 일방에는 상, 하 슬립기어(11)(12)가 설치되며 이들 사이에 휄트(13)가 설치된다.10 is a connecting piece, the idler 6 is installed on one side thereof, and the upper and lower slip gears 11 and 12 are installed on one side thereof, and a bolt 13 is installed therebetween.
14는 작동편으로 비틀림스프링(17)으로 탄력설치되고 이의 일단에 록킹기어(16)가 설치되며 록킹기어(16)는 상, 하 슬립기어(11)(12)가 치합 가능하도록 하고 작동편(14)의 일측단에 작동부(15)를 형성한다.14 is elastically installed by the torsion spring (17) as the working piece and the locking gear 16 is installed at one end thereof, the locking gear 16 is the upper and lower slip gears (11) and 12 to be engaged with each other. The operation unit 15 is formed at one end of the 14).
이상과 같이 구성된 본 고안은 데크(1)의 하방에 설치된 캡스턴 모터(2)가 구동되면 이에 따라 캡스턴 기어(3) 캡스턴축(4)을 돌려 주며 이와 동시에 밸트(7)에 연결된 슬립기어(11)를 회동시키고 이에 치합된 아이들러(6)를 구동시키며 아이들러(6)가 릴어셈블리(5)를 회동시켜 테이프가 주행한다.The present invention configured as described above, when the capstan motor (2) installed below the deck (1) is driven accordingly to rotate the capstan gear (3) capstan shaft (4) and at the same time slip gear 11 connected to the belt (7) ) Rotates and drives the idler 6 engaged with it, and the idler 6 rotates the reel assembly 5 so that the tape travels.
이와 같은 본 고안은 제1도에서와 같이 회동되는 캠(8)의 작동홈(9)에 작동편(14)의 작동부(15)가 삽입되면 작동편(14)에 설치된 록킹기어(16)가 슬립기어(11)(12)를 동시에 돌려주며 이에 따라 아이들러(6)를 슬립 등의 간섭을 받지 않는 상태로 릴어셈블리(5)를 구동시키게 되고 이때가 테이프의 되감기 또는 빨리감기 동작을 할 때이다.The present invention has a locking gear 16 installed in the operating piece 14 when the operating part 15 of the operating piece 14 is inserted into the operating groove 9 of the cam 8 that is rotated as in FIG. 1. Rotates the slip gears 11 and 12 at the same time, thereby driving the reel assembly 5 without the interference of the slipper 6 and the like. In this case, the tape is rewound or fast rewound. to be.
한편, 캠(8)이 회동하여 이의 작동홈(9)에 있던 작동편(14)의 작동부(15)를 밀어내면 작동편(14)이 제2도에서와 같이 회동되고 슬립기어(11)(12)에 치합되어 있던 록킹기어(16)가 해제되면 슬립기어(11)(12)는 휄트(13)에 의해 슬립되면서 아이들러(6)와 릴어셈블리(5)를 회동시킨다.On the other hand, when the cam 8 rotates and pushes the operating part 15 of the operating piece 14 in its operating groove 9, the operating piece 14 is rotated as shown in FIG. 2 and the slip gear 11 is rotated. When the locking gear 16 engaged with (12) is released, the slip gears 11 and 12 slide by the bolts 13 to rotate the idler 6 and the reel assembly 5.
슬립기어(11)(12)가 휄트(13)의 간섭을 받게 되면 아이들러(6)의 회동이 둔화되며 이는 테이프의 주행상태를 조절하는 상태로 회동하고 이때 테이프의 플레이 동작시기이다.When the slip gears 11 and 12 are subjected to the interference of the bolts 13, the rotation of the idler 6 is slowed down, which rotates to a state in which the running state of the tape is adjusted, and is the timing of the play operation of the tape.
비틀림 스프링(17)은 작동편(14)의 복귀동작을 시킨다.The torsion spring 17 causes the operation piece 14 to return.
이상과 같은 본 고안은 간단한 구조의 동력절화장치로 아이들러의 동작시기를 조절하게되므로 테이프의 감기는 속도를 항시 일정하게 유지시킬 수 있고 동작이 원활하게 되는 점 등의 특징을 지닌 것이다.The present invention as described above is characterized by the fact that it is possible to maintain the constant speed of the tape at all times and smooth operation because it adjusts the operation time of the idler with a power saving device of a simple structure.
