본 고안은 자기기록 재생장치의 릴 제동장치에 관한 것으로, 특히, 릴의 역회전시 회전부재와 제동부재만으로 내.외경의 마찰력을 수진 토오크(torque)로하여 제동시킬 수 있도록 한 자기기록 재생장치의 릴 제동장치에 관한 것이다.The present invention relates to a reel braking device of a magnetic recording and reproducing apparatus, and more particularly, a magnetic recording and reproducing apparatus capable of braking the frictional force of the inner and outer diameters by using a torque torque only by the rotating member and the braking member during reverse rotation of the reel. Reel braking system.
종래 일반적인 릴 제동장치는 제1도에서 도시한 바와같이, 미끄럼부재(200)와 제동부재(400)간에 스프링(500)이 장설되어 미끄럼부재(200)의 마찰력에 의해 릴의 역회전시 제동부재(400)가 시계방향으로 식입되면서 제동, 특별모드(mode)에서 제동이 필요할 경우 레버(lever)(300)에서 외력을 주어 제동시킬 수 있도록 구성되어 있다.In the conventional general reel braking device, as shown in FIG. 1, a spring 500 is installed between the sliding member 200 and the braking member 400 so that the braking member is rotated when the reel is rotated by the frictional force of the sliding member 200. When the 400 is inserted in the clockwise direction, the braking is required in a special mode (mode), the lever 300 is configured to brake with an external force.
즉, 릴 디스크(reel disk)(100)측면과 미끄럼부재(200)가 첩촉되면서 동작하는 것으로, 릴의 정회전(시계방향)시 (Play, FF FPS) 미끄럼부재(200)는 반시계방향으로 회전력이 발생되면서 릴 디스크(reel disk)(100)의 기어에서 멀어지는 방향으로 이탈되게 된다.That is, the side of the reel disk (reel disk) 100 and the sliding member 200 is in contact with the operation, the forward rotation (clockwise) of the reel (Play, FF FPS) sliding member 200 in the counterclockwise direction As the rotational force is generated, it is separated in a direction away from the gear of the reel disk 100.
한편, 릴의 역회전(반시계방향)시 (RPS, REW)에는 미끄럼부재(200)는 시계방향으로 회전력이 발생되면서 릴 디스크(reel disk)(100)의 기어에 제동부재(400)가 식입(끼임)되어 제동을 기할 수 있는 구성을 취하고 있다.On the other hand, during the reverse rotation (counterclockwise) of the reel (RPS, REW), the sliding member 200 is rotated in the clockwise direction while generating a rotational force, the braking member 400 is inserted into the gear of the reel disk (100) It takes a structure that can be caught and braked.
그러나 이같은 기술수단의 것에 있어서는, 스프링과 같은 탄성부재가 필연적으로 요구되며 레버와 같은 외력작용부재와 조합되어야만 수진력이 발생되는 등의 문제점이 있었다.However, in the technical means, there is a problem that an elastic member such as a spring is inevitably required, and water pressure is generated only when combined with an external force acting member such as a lever.
본 고안은 전술한 바와같은 종래의 제반결점을 해결하기 위하여 안출한 것으로, 회전부재의 내경부와 제동부재의 외경부 상호간의 마찰력에 의해, 정회전시 이탈되었다가 역회전시에는 제동부재가 릴치형으로 식입되게 함으로써 원활하고도 확실한 제동을 기할 수 있도록 한 자기기록 재생장치의 릴 제동장치를 제공하고자 함에 그 목적이 있다.The present invention was devised to solve the above-mentioned general defects, and the braking member was detached in the reverse rotation by the friction force between the inner diameter of the rotating member and the outer diameter of the braking member. It is an object of the present invention to provide a reel braking device of a magnetic recording and reproducing apparatus which enables smooth and reliable braking by being implanted in

It is explanatory drawing.
도시예에서와 같이 본 고안은 릴 디스크(reel disk)(1)의 기어부(11)에 치합되는 상응 기어부(22)를 갖는 회전부재(2)와, 이의 축(23)에 삽입설치되는 제동부재(3)와로 조합 구성되어 상기 릴 디스크(reel disk)(1)의 정.역 회동에 따라 제동부재(3)가 릴 디스크(reel disk)(1)를 선택적으로 제동시킬 수 있는 기본구조를 취하고 있다.As shown in the example, the present invention is provided with a rotating member 2 having a corresponding gear portion 22 engaged with the gear portion 11 of the reel disk 1, and a shaft 23 inserted therein. Composed of the braking member 3 and the basic structure in which the braking member 3 can selectively brake the reel disk 1 according to the forward / reverse rotation of the reel disk 1. Is taking.
상기 회전부재(2의 축(23) 상부 외주면에는 마찰부(21)가 형성되어 있으며 이는 제동부재(3)의 상응 마찰부(31),(32),(33)와 일정 마찰을 일으킬 수 있는 구조를 취하고 있다.A friction portion 21 is formed on the upper outer circumferential surface of the shaft 23 of the rotating member 2, which may cause constant friction with the corresponding friction portions 31, 32, and 33 of the braking member 3. It is taking structure.
상기의 제동부재(3)측 마찰부(31),(32),(33)는 회전부재(2)의 축(23)이 끼워지는 원통형 보스(boss)(36)에 소정의 일정간격을 갖는 절개홈(35)들간의 방사상 첨예부가 내향 돌출 형성된 구성을 취한다.The braking member (3) side friction portion 31, 32, 33 has a predetermined interval to the cylindrical boss (36) to which the shaft 23 of the rotating member (2) is fitted. Radial sharpness between the cutouts 35 takes a configuration in which the inwardly projected portions are formed.
또한, 상기 제동부재(3)의 일측에는 릴 디스크(reel disk)(1)의 기어부(11)에 선택적으로 식입되어 제동을 기할 수 있는 제동식입부(34)가 일체로 돌출 형성되어 있다.In addition, one side of the braking member 3 is integrally formed with a braking insertion portion 34 which is selectively implanted into the gear portion 11 of the reel disk 1 to enable braking.
도면중 미 설명부호 4는 베이스(base)(5)에 수직 설치되어 상기 회전부재(2)의 축(23)에 끼워질 수 있는 축봉을 나타낸 것이다.In the drawings, reference numeral 4 denotes a shaft that is vertically installed on the base 5 and may be fitted to the shaft 23 of the rotating member 2.
이와같은 구성으로 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention with such a configuration as follows.
본 고안은 릴 디스크(reel disk)(1)와 회전부재(2)가 상호 접속회전하고 제동부재(3)는 상기 회전부재(2)와 내경부 3점 몰드물(마찰부)의 지지에 의해 일정 압으로 눌려져(압압) 일체화로 회전력을 받게된다.The present invention is a reel disk (1) and the rotating member (2) rotates interconnected, the braking member (3) by the support of the rotating member (2) and the inner diameter three-point mold (friction) It is pressed by a certain pressure (pressing pressure) and receives rotational force by integration.
예컨대, 릴 디스크(reel disk)(1)의 정회전시 즉, PALY, FF, FPS모드시의 릴 디스크(1)가 시계방향으로 회전할때, 회전부재(2)는 상호 치합구동에 의해 반시계방향으로 회전하게 된다.For example, when the reel disk 1 rotates clockwise in the forward rotation of the reel disk 1, that is, in the PALY, FF, and FPS modes, the rotating member 2 is counterclockwise by mutual engagement driving. Direction of rotation.
이때, 제동부재(3)는 그 마찰부(21)가 회전부재(2)의 마찰부(31),(32),(33)에 의해 적정치로 압압된 상태이나 회전이동을 간섭받지 않는 상태이므로 회전부재(2)와 같이 반시계방향으로 회동력을 부여받아 릴 디스크(1)의 기어부(11)로부터 이탈된 상태를 취하게 된다.At this time, the braking member 3 is a state in which the friction portion 21 is pressed to the appropriate value by the friction portion 31, 32, 33 of the rotating member 2 or does not interfere with the rotational movement Therefore, the rotational force is applied in the counterclockwise direction as in the rotating member 2 to take a state separated from the gear portion 11 of the reel disk 1.
따라서, 릴 디스크(reel disk)(1)의 정회전(시계방향)시에는 그 제동이 이루어지지 않게 되다.Therefore, the braking is not performed during the forward rotation (clockwise) of the reel disk 1.
한편, RPS라든가 REW모드시에는 릴 디스크(reel disk)(1)가 역회전(반시계방향)하게 되는바, 회전부재(2)는 시계방향으로 회전하여 제동부재(3)를 정회전 방향으로의 회동시키게 된다.On the other hand, in the RPS or REW mode, the reel disk 1 is rotated in the reverse direction (counterclockwise). The rotating member 2 rotates clockwise to rotate the braking member 3 in the forward rotation direction. Will be rotated.
이때, 제동부재(3)는 그 마찰부(31),(32),(33)가 회전부재(2)의 상응 마찰부(21)에 적정치로 밀착된 상태를 취하고 있음으로써 제동식입부(34)가 릴 디스크(reel disk)(1)의 기어부(11)에 식입(끼임)되어 제동이 이루어지게 되는 것이다.At this time, the braking member 3 has a state in which the friction portions 31, 32, 33 are in close contact with the corresponding friction portion 21 of the rotating member 2 at an appropriate value. 34 is inserted (pinched) into the gear portion 11 of the reel disk 1 so that braking is performed.
이상에서 상술한 바와같이 본 고안의 자기기록 재생장치의 릴 제동장치에 의하면, 비교적 간단한 구성으로 원활하면서도 확실한 릴 제동을 기할 수 있는등의 특단의 효과가 기대된다.As described above, according to the reel braking device of the magnetic recording and reproducing apparatus of the present invention, a special effect is expected such that smooth and reliable reel braking can be performed with a relatively simple configuration.
