종래의 더블데크 카세트에서는 더빙시 녹음 덱크를 먼저 동작시킨 후 재생데크를 동작시킬 경우, 먼저 동작된 녹음데크내의 테이프에는 재생데크가 동작하기까지 콘덴서 마이크등을 통해서 불필요한 외부의 잡음이 녹음되게 되며, 또한 이와 반대로 재생데크를 먼저 동작시킨 후 녹음데크를 나중에 동작시키면, 녹음데크가 동작하기 까지 재생데크에서 재생된 신호가 녹음이 되지 않는 폐단이 있었다.In the conventional double deck cassette, when the recording deck is operated first when dubbing, and then the playback deck is operated, unnecessary external noise is recorded on the tape in the previously operated recording deck through the condenser microphone, etc. until the playback deck is operated. On the contrary, when the recording deck was operated first, and then the recording deck was operated later, there was a closed stage in which the signal reproduced from the playback deck was not recorded until the recording deck was operated.

또한 사용자가 안쪽 덱크를 동시에 동작시키기 위해서는 양손을 사용하여 각 데크의 해당버튼을 동시에 눌러주어야 하기 때문에 더빙시의 조작이 번거로워지게 된다.In addition, in order for the user to simultaneously operate the inner deck, both hands must press the corresponding button of each deck at the same time, so the operation during dubbing becomes cumbersome.

본 고안의 목적은 상기와 같은 단점을 해결하기 위하여 더빙시 먼저 녹음데크의 해당버튼을 눌러도 녹음데크는 동작하지 않는 상태에 있다가 재생데크의 재생버튼을 눌러주어야만 녹음데크와 재생데크가 동시에 동작되도록 안출한 것으로서, 이하 본 고안의 구성, 작용 및 효과를 첨부도면에 의해 성세히 설명한다.The purpose of the present invention is to solve the above drawbacks when recording, the recording deck does not work even if you press the corresponding button of the recording deck first, so that the recording deck and the playback deck to operate at the same time only if you press the play button of the playback deck As devised, the configuration, operation and effects of the present invention will be described in detail by the accompanying drawings.

At the same time, the transistor (Q) is coupled to the recording mode contact (R) of the contact (a) and the selector switch (SW 1 ') of the leaf switch (SW 3 ) through the resistor (R 2 ). 2 ) to the base of the selector switch (SW 1 ), connected to the base of the transistor (Q 1 ) through the diode D 3 and the resistor (R 1 ), The collector is connected to the other contact OFF of the control switch SW 4 and the motor MT 1 , and the reproduction mode contact P of the selection switch SW 1 ′ is connected to the transistor Q. 2 ) And a motor (MT 1 ) and a junction between the diode (D 3 ) and the resistor (R 1 ) through a diode (D 4 ), where 1 is an output amplifier. Circuit, 2 is bias oscillator circuit, B + is DC power supply terminal, RB + , PB + and AB + are B + power input terminals D 1 , D 2 , D 5 for radio, record player and external signal input mode respectively. -D 7 is a diode.

이와 같이 구성된 본 고안의 회로동작상태를 더빙시와 연속재생시로 구분하여 설명한다.The circuit operation state of the present invention configured as described above will be described by dividing into dubbing and continuous playback.

먼저, 더빙시에는 선택스위치(SW1) (SW1')의 접점을 각각 녹음모우드 접점(R)에 절환시키고, 제어스위치(SW4)를 '온'시켜 그 접점(C)을 접점(ON)에 절환시키게 되며, 이때 선택스위치(SW1)의 접점(R)을 통해 바이어스발진회로(2)로 B+전원이 공급된다.First, when dubbing, switch the contacts of the selection switch SW 1 (SW 1 ') to the recording mode contact R, respectively, and turn on the control switch SW 4 to turn on the contact C. ), And B + power is supplied to the bias oscillation circuit 2 through the contact point R of the selector switch SW 1 .

이와 같은 상태에서 먼저 녹음데크내의 녹음 버튼을 누르면 리이프스위치(SW2)가 '온'되므로 그 접점(a)(b)을 통해 B+전원이 트랜지스터(Q1)의 콜렉터에 공급된다.In such a state, when the record button in the recording deck is first pressed, the leaf switch SW 2 is 'on', so that B + power is supplied to the collector of the transistor Q 1 through the contacts (a) and (b).

그러나 이 트랜지스터(Q1)의 베이스에는 바이어스전압이 걸리지 않으므로 이 트랜지스터(Q1)는 '오프'되어 녹믐 데크용 모우터(MT1)는 구동되지 않는다.However, the base of the transistor (Q 1) has a bias voltage does not take the transistor (Q 1) is Motor (MT 1) for the "off" nokmeum deck is not driven.

이후에 재생데크내의 재생버튼을 누르면 리이프스위치(SW3)가 '온'되므로, B+전원이 리이프스위치(SW3)의 접점(a)(b)과 선택스위치(SW1')의 녹음모우드접점(R)을 통해 재생데크용 모우터(MT2)로 공급되어 이 모우터(MT2)를 구동시킴과 동시에 다이오드(D1) 및 저항(R1)을 통해 트랜지스터(Q1)의 베이스로 공급되어 이 트랜지스터(Q1)를 도통시킴으로서 모우터(MT1)도 구동시키게 되는 것으로서, 이에 의해 녹음데크와 재생데크가 동시에 동작하게 된다.Afterwards, when the play button in the play deck is pressed, the leaf switch (SW 3 ) is' on ', so that B + power is turned on between the contacts (a) (b) and the selection switch (SW 1 ') of the leaf switch (SW 3 ). It is supplied to the reproduction deck motor (MT 2 ) through the recording mode contact (R) to drive the motor (MT 2 ) and at the same time the transistor (Q 1 ) through the diode (D 1 ) and the resistor (R 1 ). The transistor Q 1 is supplied to the base of the transistor to drive the motor MT 1 so that the recording deck and the reproduction deck operate simultaneously.

이때 출력앰프회로(1)로는 다이오드(D1)(D2)를 통해 전원이 공급된다.In this case, power is supplied to the output amplifier circuit 1 through the diode D 1 and D 2 .

한편, 연속재생시에는 선택스위치(SW1)(SW1')의 접점을 각각 재생모우드접점(P)에 절환시키고, 제어스위치(SW4)의 접점을 접점(OFF)에 절환시키게 된다.On the other hand, during continuous playback, the contacts of the selector switch SW 1 (SW 1 ′) are switched to the regeneration mode contact P, respectively, and the contact of the control switch SW 4 is switched to the contact OFF.

이와 같은 상태에서 녹음데크와 재생데크의 플레이버튼을 차례로 눌러주면 각 리이프스위치(SW2)(SW3)가 모두 '온'상태로 되므로, B+전원이 리이프스위치(SW2)의 접속접점(a)(b)과 제어스위치(SW4)의 접속접점(C)(OFF)를 통해 모우터(MT1)로 공급되어 이 모우터(MT1)가 구동되어 녹음데크에 의한 재생기능이 이루어진다.In this state, if you press the play buttons of the recording deck and the playback deck in turn, all of the life switches (SW 2 ) (SW 3 ) are turned on, so the B + power supply is connected to the life switches (SW 2 ). It is supplied to the motor MT 1 through the contact point (C) (OFF) of the contacts (a) and (b) and the control switch SW 4 , and the motor MT 1 is driven to play the recording deck. This is done.

이때, 트랜지스터(Q2)는 저항(R2)을 통한 B+전원공급에 의해 역바이어스상태로 되어 '오프'되므로 모우터(MT2)는 정지된 상태에 있게 된다.At this time, since the transistor Q 2 is in a reverse biased state by B + power supply through the resistor R 2 , the transistor MT 2 is in a stopped state.

이와 같은 상태에서 녹음데크내의 테이프가 끝까지 회전되어 엔딩(Ending)되면 데크내의 오토 스톱(Auto Stop)장치에 의해 리이프스위치(SW2)가 '오프'되며, 이에 의해 트랜지스터(Q1)가 '오프'되어 녹음 데크용 모우터(MT1)가 정지되는 반면, 트랜지스터(Q2)의 베이스로는 저항(R2)과 제어스위치(SW2)의 접속접점(C)(OFF) 및 모우터(MT1)의 내부코일의 직렬연결에 의한 바이어스가 걸리게 되어 이 트랜지스터(Q2)가 도통되고, 이에 의해 모우터(MT2)로는 B+전원이 공급되므로 이 모우터(MT2)가 구동되어 재생데크가 동작하게 됨으로써 연속재생모우드가 이루어지게 된다.In this state, when the tape in the recording deck is rotated to the end and the ending is completed, the life switch SW 2 is 'off' by the auto stop device in the deck, whereby the transistor Q 1 is turned off. While the recording deck motor MT 1 is stopped, the connection contact C (OFF) of the resistor R 2 and the control switch SW 2 to the base of the transistor Q 2 and the motor are stopped. is biased by a series-connected internal coil (MT 1) is caught is a transistor (Q 2) conducts, thereby Motor (MT 2) roneun since B + power supply Motor (MT 2) is driven As the playback deck is operated, a continuous playback mode is achieved.

한편, 라디오나 레코드 플레이어 또는 외부신호입력모우드 상태에서, 이를 녹음시킬 경우에는 트랜지스터(Q1)의 베이스로는 각 다이오드(D5-D7)중 선택모우드에 대응하는 하나의 다이오드가 도통되어 바이어스가 걸리게 되고, 이때 제어스위치(SW4)가 '온'된 상태에서 녹음 데크내의 버튼을 눌러 리이프스위치(SW2)를 '온'시키면 이 트랜지스터(Q1)가 도통되며, 또한 제어스위치(SW4)가 '오프'상태이면 B+전원이 직접 이 제어스위치 접점(C)(OFF)을 통해 모우터(MT1)로 공급됨으로써 상기의 제어스위치(SW4)의 '온, 오프'에 무관하게 모우터(MT)가 구동되어 녹음데크가 동작하게 된다.On the other hand, in the radio, record player or external signal input mode, when recording this, one of the diodes (D 5 -D 7 ) corresponding to the selection mode of the transistor (Q 1 ) is turned on and is biased In this case, when the control switch SW 4 is turned on, pressing the button in the recording deck to turn on the life switch SW 2 turns on the transistor Q 1 . When SW 4 ) is in the 'off' state, B + power is directly supplied to the motor MT 1 through this control switch contact C (OFF) to the 'on, off' of the control switch SW 4 . Regardless, the motor MT is driven to operate the recording deck.

이상과 같이 본 고안은 더빙시에는 녹음데크와 재생데크내의 녹음 및 재생버튼을 차례로 누르더라도 녹음데크와 재생데크가 동시에 동작하게 됨으로써 테이프의 더빙상태가 양호하고 더빙조작이 편리해지는 잇점이 있는 유용한 고안이다.As described above, the present invention has a useful design that the dubbing state of the tape is good and the dubbing operation is convenient because the recording deck and the playback deck operate simultaneously even when the recording deck and the playback button in the recording deck are pressed simultaneously when dubbing. to be.
