본 고안은 테이프 레코더에 있어서, 레코더가 동작도중 정전이 될 경우 캡스턴 축에 밀착되어 있는 핀치롤러를 분리시켜 이의 변형을 방지할 수 있도록 한 핀치롤러의 분리장치에 관한 것이다.The present invention relates to a tape recorder, wherein the pinch roller is in close contact with the capstan shaft when the recorder is out of power during operation to prevent the deformation of the pinch roller.
종래의 테이프 레코더에 있어서는 레코더가 동작도중 정전이 발생될 경우 이를 정전검출 제어회로부에서 검출제어하고 충전회로와 더불어 로딩모터를 언로딩시켜 핀치롤러를 캡스턴 축에서 분리토록 되어 있었다.In the conventional tape recorder, if a power failure occurs while the recorder is in operation, the power failure detection control circuit unit detects and controls the unloading motor together with the charging circuit to separate the pinch roller from the capstan shaft.
그러나, 이와같은 종래의 것은 회로적 구성에 의해서 핀치롤러를 분리시키므로서 회로구성에 매우 복잡하게 되어 있었고 또한 충전회로부의 콘덴서 용량을 크게 하여야만 하므로서 핀치롤러를 분리하기 위한 구성에 매우 복잡하게 이루어질수 밖에 없는등의 문제점이 있었다.However, such a conventional structure is very complicated in the circuit configuration by separating the pinch rollers by the circuit configuration, and also has to be very complicated in the configuration for separating the pinch rollers because the capacitor capacity of the charging circuit part must be increased. There was a problem.
본 고안은 상기와 같은 종래의 제반 문제점을 감안하여 핀치롤러를 로딩기어로서 구동시키도록 하고 정전시에는 스프링의 탄력만으로 핀치롤러를 분리시킬수 있도록 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is designed to drive the pinch rollers as a loading gear in view of the above-mentioned conventional problems, and in the event of a power outage, the pinch rollers can be separated only by the elasticity of the spring. Same as
데크(1)의 일방에 설치되는 로딩기어(2)에 가이드홈(3)을 형성하고 이에 핀(4)으로서 걸림턱(6)을 가진 작동구(5)를 설치하여 작동구(5)는 로딩기어(2)에 스프링(7)으로 탄력 설치한다.The guide groove 3 is formed in the loading gear 2 installed on one side of the deck 1, and the operation tool 5 is installed by installing the operation tool 5 having the locking jaw 6 as the pin 4. Resilient installation with a spring (7) to the loading gear (2).
상기 로딩 기어(2)의 일방에는 로딩모터(8)를 설치하고 이들 사이에는 연결기어 (9)(10)(11)와 제어기어(12)를 설치하여 제어기어(12)의 하부에는 고정판(121)을 설치하고 이의 하방에는 고정판(121)과 착탈될 수 있도록 솔레노이드(13)를 설치한다.A loading motor 8 is installed on one side of the loading gear 2, and connecting gears 9, 10, 11, and controller gear 12 are installed between them, and a fixed plate is disposed below the controller gear 12. 121) and the solenoid 13 is installed below the fixing plate 121 to be attached and detached.
상기 로딩모터(8) 와 솔레노이드(13)에는 드라이버(14)와 제어부(15)를 연결하고 제어부(15)와 솔레노이드(13)사이에는 트랜지스터(16)를 연결 설치하고 솔레노이드(13)의 일단에는 전원부에 연결한다.The driver 14 and the control unit 15 are connected to the loading motor 8 and the solenoid 13, and the transistor 16 is connected between the control unit 15 and the solenoid 13, and at one end of the solenoid 13. Connect to the power supply.
상기 로딩기어(2)의 일측하방에는 핀치암(17)에 설치되는 핀치롤러(18)를 스프링(19)으로 탄력 설치시키되, 이는 데크(1)상에 형성된 원호상의 안내장공(101)에 관통 설치하며 핀치롤러(18)는 상기 작동구(5)에 의하여 켑스턴 축(20) 사이에서 구동되도록 설치 구동하여서 된 것이다.Under one side of the loading gear 2, the pinch roller 18, which is installed on the pinch arm 17, is elastically installed with a spring 19, which penetrates through the circular guide hole 101 formed on the deck 1. The pinch roller 18 is installed and driven so as to be driven between the shaxton shafts 20 by the operation tool 5.
이상과 같이 구성된 본 고안은 전원이 ON되어 있는 상태에서 카세트를 장착하고 로딩동작을 시키게 되면 제어부(15)에서 C1과 C2가 출력하며 이때 C2가 로우 (LOW)신호를 출력하게 되면 트랜지스터(16)는 OFF되고 솔레노이드(13)는 고정판 (121)에서 떨어지게 되어 동작하지 않게 되면 C1의 출력에 의해서 드라이버(14)가 구동되고 로딩모터(8)가 구동된다.The subject innovation constituted as described above is when the power is Let it to be attached to the cassette and loading operation in a state where ON is C 1 and C 2 output from the control section 15 and wherein C 2 is to output a low (LOW) signal transistor When 16 is turned off and the solenoid 13 is removed from the fixed plate 121 and is not operated, the driver 14 is driven by the output of C 1 and the loading motor 8 is driven.
로딩모터(8)가 구동하면 이의 구동기어에 연결된 제어기어(12)와 각 연결기어 (9)(10)(11)가 회동하게 됨에 따라 로딩기어(2)가 동작하기 시작한다.When the loading motor 8 is driven, the loading gear 2 starts to operate as the controller gear 12 connected to the driving gear 12 and the respective connecting gears 9, 10, 11 are rotated.
로딩기어(2)가 회동하면 이의 가이드홈(3)상에 핀(4)으로 설치된 작동구(5)가 스프링(7)의 힘으로 로딩기어(2)와 함께 이동하게 되고 작동구(5)의 걸림턱(6)이 핀치암(17)에 설치된 핀치롤러(18)를 안내장공(101)상에서 끌고 아동시키게 되며 핀치롤러(18)는 이의스프링(19)에 의해 탄력을 가지면서 캡스턴 축(20)에 밀착되면 제어부(15)는 드라이버(14)를 제어하여 로딩모터(8)를 정지시키고 동시에 C2를 하이 (HIGH)로 하여 트랜지스터(16)를 ON시키게 되며 이에 따라 솔레노이드(13)가 작동하여 제어기어(12)의 하부에 부착 설치된 고정판(121)에 밀착 고정되어 제어기어 (12)를 록킹시켜 로딩동작을 완료시키게 되며 이때 작동구(5)는 핀치롤러(18)에 걸려있는 상태로 스프링(7)만 인장되어 있다.When the loading gear 2 rotates, the actuating tool 5 installed by the pin 4 on the guide groove 3 thereof moves with the loading gear 2 by the force of the spring 7 and the actuating tool 5 The catching jaw 6 of the pinch roller 18 installed on the pinch arm 17 is dragged and guided on the guide hole 101 and the pinch roller 18 is elastic by the spring 19 of the capstan shaft ( 20, the control unit 15 controls the driver 14 to stop the loading motor 8 and at the same time turn on the transistor 16 by turning C 2 high and thus the solenoid 13 is turned on. It is operated to be tightly fixed to the fixed plate 121 attached to the lower portion of the control gear 12 to lock the control gear 12 to complete the loading operation, the operation hole 5 is caught in the pinch roller 18 Only the furnace spring 7 is tensioned.
이와같이 로딩된 상태에서 언로딩을 시키면 제어부(15)가 동작하여 솔레노이드 (13)를 OFF시키고 로딩모터(8)만을 구동시켜 로딩기어(2)를 복귀시키고 작동구(5)와 함께 핀치롤러(18)가 스프링(19)에 의해 복귀된다.When unloading is performed in the loaded state, the control unit 15 operates to turn off the solenoid 13, drive only the loading motor 8 to return the loading gear 2, and the pinch roller 18 together with the operation tool 5. ) Is returned by the spring 19.
상기와 같은 동작에 있어서, 만인 로딩상태에서 정전이 발생되면, 전원 자체가 차단되므로 솔레노이드(13)가 OFF되고 로딩기어(2)는 복귀할 수 없는 상태가 된다.In the above operation, when a power failure occurs in the full loading state, the power supply itself is shut off, so the solenoid 13 is turned off and the loading gear 2 is in a state in which it cannot return.
이때 작동구(5)에 설치된 스프링(7)과 핀치암(17)에 설치된 스프링(19)이 복귀력을 발휘하게 되며 이에따라 로딩기어(2)에 설치된 작동구(5)가 스프링(7)의 복귀력에 의해 핀치롤러(18)가 캡스턴 축(20)에서 분리되는 것이다.At this time, the spring (7) installed on the operating port (5) and the spring (19) installed on the pinch arm (17) exert a return force, and accordingly the operating port (5) installed on the loading gear (2) is The pinch roller 18 is separated from the capstan shaft 20 by the return force.
이상과 같은 본 고안은 제어부는 로딩모터와 솔레노이드만을 구동시키고 정전시의 핀치롤러의 분리는 스프링만으로 행할 수 있기 때문에 종래와 같이 복잡한 회로구성이 필요없으며 동작이 확실하고 원활하게 이루어지는 점등의 특징을 지닌 것이다.As described above, the control unit drives only the loading motor and the solenoid, and the pinch roller can be separated only by the spring during power failure, and thus does not require a complicated circuit configuration as in the prior art. will be.
