본 고안은 테이프 레코더의 릴 제동장치에 관한 것으로서, 특히 고속주행후 급제동을 위한 릴제동 장치에 관한 것이다.The present invention relates to a reel braking device of a tape recorder, and more particularly, to a reel braking device for rapid braking after a high speed drive.

일반적으로 테이프 레코더에는 테이프 릴을 안착 구동 시키는 릴 디스크 주위에 제동기구가 설치되는데, 이 제동기구(brake)는 릴 디스크를 정지시켜 그에 안착된 테이프 릴로부터 테이프가 풀려나가는 것을 방지하는 역할을 한다. 특히 이 제동기구는 고속주행후 다른 모드로 전환될때 급속히 정지 되어야 하므로 이를 위한 급제동장치를 필요로 하는 것이다.In general, a tape recorder is provided with a braking mechanism around a reel disk for seating and driving a tape reel. The brake mechanism stops the reel disk to prevent the tape from being released from the tape reel seated thereon. In particular, the braking mechanism needs to be stopped quickly when switching to another mode after high-speed driving, and therefore a rapid braking device is required.

급제동을 위한 제동장치로서 종래 라체트를 이용한 장치가 실용 신한 공보 공고번호 제 88-657호로 공지된바 있는데 이것을 포함한 대부분의 종래 장치는 제동기구 작동판으로서 2중 구조를 취하고 있으며 또 그 순간적인 작동을 위해 복잡한 기구들을 포함시키는 등 매우 복잡한 구조로 되어 있어 여러가지 문제점을 가지고 있고, 특히 오동작이 자주 발생되었 것이다.As a braking device for rapid braking, a device using a ratchet has been known as Practical Publication No. 88-657. Most conventional devices including this have a double structure as a braking mechanism operating plate and provide instantaneous operation. It has a very complicated structure, such as to include a complex mechanism for the various problems, especially malfunctions will occur frequently.

따라서 본 고안의 목적은 단일한 작동판을 사용하되 그 구동기구인 캠과 캠레버가 정지 시점에서 순간적인 변위를 갖게 하여 간단하고 효과적인 급제동장치를 제공하려는 것이다.Therefore, the object of the present invention is to provide a simple and effective rapid braking device by using a single operating plate but the cam and cam lever, which are the driving mechanisms, have a momentary displacement at the stop point.

상기한 목적을 달성하기 위해 본 고안은, 축에 결합된 회전 핀을 갖는 모터와, 소정의 제1 및 제2 캠홈이 형성되고 상기 모터로 구동되는 캠기어와, 상기 제1 및 제2 캠홈에 의하여 각각 회동하며 상기 회전핀에 의하여 해제될 수 상호간의 록킹 수단을 구비하는 제1 및 제2 캠레버와, 어느 한 방향으로 탄성 바이어스되고 상기 제1 캠레버에 의하여 왕복운동하는 작동판과, 어느 한 방향으로 탄성 바이어스되고 상기 작동판에 의하여 동작하는 릴 디스크의 제동기구로 결합시킴을 특징으로 한다.In order to achieve the above object, the present invention provides a motor having a rotating pin coupled to a shaft, a cam gear formed with predetermined first and second cam grooves and driven by the motor, and the first and second cam grooves. First and second cam levers each having a locking means mutually rotated and disengaged by the rotation pins, an operating plate elastically biased in either direction and reciprocating by the first cam levers, It is characterized in that it is coupled to the braking mechanism of the reel disk which is elastically biased in one direction and operated by the operating plate.

이하, 본 고안의 한 실시예를 첨부된 도면에 의거하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제1도에서 부호 10은 모터, 20은 캠기어, 30과 40은 제1 및 제2 캠레버, 50은 작동판, 60은 제도기구 그리고 70은 릴 디스크이다.In Fig. 1, reference numeral 10 is a motor, 20 is a cam gear, 30 and 40 are first and second cam levers, 50 is a working plate, 60 is a drawing mechanism, and 70 is a reel disk.

모터(10)에는 그 축에 결합되어 함께 회전하는 회전핀(11)과 웜(12)이 구비되고, 이 웜(12)에 동축 웜기어(13)가 물려 캠기어(20)를 진동시킨다.The motor 10 is provided with a rotating pin 11 and a worm 12 which are coupled to the shaft and rotate together, and the worm 12 is engaged with the coaxial worm gear 13 to vibrate the cam gear 20.

캠기어(20)에는 소정의 곡류로 그 반경을 변화시키는 제1 및 제2 캠홈(21) (22)이 형성되고 이중 제1캠홈(21)의 종단부(21a)가 넓게 되어 있다.The cam gear 20 is formed with first and second cam grooves 21 and 22 for changing the radius of the predetermined grains, and the end portion 21a of the first cam groove 21 is wide.

제1 및 제2 캠레버(30) (40)에는 상기 제1 및 제2 캠홈(21) (22)에 각각 삽입되는 가이드 보스(31) (41)가 각각 구비되고 그들 상호간의 록킹수단으로서 제1 캠레버(30)에는 록킹핀(32)이, 그리고 제2 캠레버(40)에는 록킹스프링(43)에 탄지되고 양단에 상기 록킹핀(32)의 걸림턱(42a)과 상기 회전핀(11)의 연동부(42b)를 가지는 록킹레버(42)가 각각 설치되어 있다. 작동판(50)은 작동 스프링(51)에 탄지되고, 그 일축부에 작동요홈(52)이 형성되어 있다.The first and second cam levers 30 and 40 are provided with guide bosses 31 and 41 respectively inserted into the first and second cam grooves 21 and 22, respectively, and are formed as locking means therebetween. The locking pin 32 is attached to the first cam lever 30 and the locking spring 43 is attached to the second cam lever 40, and both ends of the locking jaw 42a of the locking pin 32 and the rotation pin ( Locking levers 42 each having an interlocking portion 42b of 11) are provided. The operation plate 50 is supported by the operation spring 51, and the operation groove 52 is formed in one shaft portion thereof.

그리고, 제동기구(60)에는 릴 디스크(70) 주파수에 접촉될 수 있는 제동면(61)과 제동아암(62)을 가지며, 제동스프링(63)에 탄지되어 상기 작동판(50)에 연동된다.In addition, the braking mechanism 60 has a braking surface 61 and a braking arm 62 which may be in contact with the reel disk 70 frequency, and is supported by the braking spring 63 and interlocked with the operation plate 50. .

제2도를 참조하면, 캠기어(20)가 시계 방향으로 회전할때 제1 및 제2 캠레버(30)(40)의 각 가이드보스(31) (41)가 좌측으로 변위되고, 제1 캠레버(30)에 연결된 작동판(50)은 우측으로 당겨진다. 이때 제동기구(60)의 제동아암(62)은 작동판(50)의 작동요홈(52)을 벗어나므로 그 제동면(61)이 릴 디스크(70)로 부터 이격되게 된다.Referring to FIG. 2, when the cam gear 20 rotates in the clockwise direction, each of the guide bosses 31 and 41 of the first and second cam levers 30 and 40 is displaced to the left. The operation plate 50 connected to the cam lever 30 is pulled to the right. At this time, the braking arm 62 of the braking mechanism 60 is out of the working groove 52 of the operating plate 50 so that the braking surface 61 is spaced apart from the reel disk 70.

상기 제1 캠레버(30)의 가이드 보스(31)는 그 제1 캠홈(21)의 다른 구간 보다 넓은 종단부(21a)에 위치하여 상기 작동판(50)이 작동스프링(51)의 힘을 받지만 그 록킹핀(32)이 록킹레버(42)의 걸림턱(42a)에 걸려 변위되지 않는다.The guide boss 31 of the first cam lever 30 is positioned at a wider end portion 21a than the other section of the first cam groove 21 so that the operating plate 50 can apply the force of the operating spring 51. Although the locking pin 32 is caught by the locking jaw 42a of the locking lever 42, it is not displaced.

또한 제3도를 참조하면, 록킹레버(42)가 그를 지지하는 제2 캠레버(40)에 의하여 이동되어 그 연동부(42b)를 회전핀(11) 아래에 위치시킨다. (제4도(a) 참조)Also referring to FIG. 3, the locking lever 42 is moved by the second cam lever 40 supporting it to position the linkage 42b below the rotary pin 11. (See Figure 4 (a))

이러한 상태는 테이프 언로딩을 완료하고 테이프를 빨리 감거나 되감는 고속 주행 모드의 상태이다.This state is a high speed driving mode in which the tape unloading is completed and the tape is fast rewound or rewound.

고속 주행 모드에서 다른 모드로 변환시켜 주면 일단 스톱모드로 되는데 이때 모터(10)는 역전된다.When the switch from the high speed driving mode to another mode, once the stop mode, the motor 10 is reversed.

모터(10)가 역전하면, 제4도(b)와 같이 회전핀(11)에 의해 록킹레버(42)의 연동부(42a)가 밀쳐지고, 이에따라 제2도에서와 같이 록킹핀(32)에서 그 걸림턱(42a)이 해제된다. 이와 동시에 제1 캠레버(30)의 가이드보스(31)가 작동판(50)의 작동 스프링(51)의 힘으로 순식간에 우측으로 이동하게 되어 제1 캠레버(30)가 순간적으로 연동되고 작동판(50) 역시 순간적인 속도로 좌측으로 이동된다.When the motor 10 is reversed, the linking portion 42a of the locking lever 42 is pushed by the rotating pin 11 as shown in FIG. 4 (b), and accordingly, the locking pin 32 as shown in FIG. The locking jaw 42a is released. At the same time, the guide boss 31 of the first cam lever 30 is immediately moved to the right side by the force of the operating spring 51 of the operating plate 50 so that the first cam lever 30 is interlocked momentarily and operated. The plate 50 is also moved to the left at an instantaneous speed.

그리하여 그 작동요홈(52)이 제동기구(60)의 제동아암(62)측에 위치되어 제동기구(60)는 그 제동스프링(63)의 힘으로 신속히 움직여 그 제동면(61)을 릴 디스크(70)에 순간적으로 접촉 시킨다.Thus, the operation groove 52 is located on the braking arm 62 side of the braking mechanism 60 so that the braking mechanism 60 can be moved quickly by the force of the braking spring 63 to move the braking surface 61 to the reel disk ( 70) instantaneous contact

결국 릴 디스크(70)는 모드 변환과 동시에 급제동되므로 테이프 풀림을 방지하는 것이다.As a result, the reel disk 70 is braked at the same time as the mode change, thereby preventing tape loosening.

다시 다른 모드를 수행하기 위하여 모터(10)가 정방향으로 구동되면, 제1 및 제2 캠레버(30) (40).When the motor 10 is driven in the forward direction to perform another mode again, the first and second cam levers 30 and 40.

록킹레버(42)등 모두 제 위치로 돌아간다.All of the locking levers 42 and the like return to their positions.

이상에서 설명한 바와같이, 본 고안 장치는 캠과 캠레버가 정지 시점에서 순간적인 변위를 갖게하여 급제동을 가능케 하는 것으로서 종래 이중 작동판을 사용하는 것보다 그 구성이 간단하고 확실한 동작을 하여 제품의 신뢰도 향상등 기여하는 바가 큰 효과적인 고안이라 하겠다.As described above, the device of the present invention allows rapid braking by allowing the cam and the cam lever to have a momentary displacement at the point of stopping, and thus, the configuration is simpler and more reliable than that of the conventional dual operation plate, thereby ensuring the reliability of the product. It is an effective design that contributes to improvement.
