이와같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention configured in this way in detail as follows.

전원단자(B+)에 전원이 인가되고, 연속재생을 할 경우 즉, 녹음/재생선택스위치(SW3)를 재생선택단자(PB1)에 단락시킴과 아울러 제1및 제2데크의 재생버튼을 눌러 제1데크재생스위치(SW1)및 제2데크녹음/재생스위치(SW2)가 단락되면, 상기 녹음/재생선택스위치(SW3)가 재생선택단자(PB1)에 단락됨에 따라 트랜지스터(TR4)(TR5)가 오프되고, 또한 상기 제1데크재생스위치(SW1)가 단락됨에 따라 전원단자(B+)의 전원이 그 스위치(SW1)를 통해 제1데크구동모타(M1)에 인가되어 그가 구동됨과 아울러 저항(R1)을 통해 트랜지스터(TR1)의 베이스에 인가되나, 그의 콜렉터에 저전위 신호가 인가되어 있으므로 그가 오프되고, 그 전원단자(B+)의 전원은 저항(R2)(R3)을 다시 통해 트랜지스터(TR2)의 베이스에 인가되어 그가 온되고, 또한 상기에서 제2데크녹음/재생스위치(SW2)가 온되어 있으므로 전원단자(B+)의 전원이 저항(R4)을 통해 트랜지스터(TR3)의 베이스에 인가되어 그가 온되고 이에 따라 전원단자(B+)의 전원이 저항(R7)및 트랜지스터(TR2)(TR3)를 통해 접지되므로 트랜지스터(TR6)(TR10)의 베이스에 저전위 신호가 인가되어 그가 오프되고, 이에 따라 제2데크구동모타(M2)는 구동되지 않게되고, 또한, 트랜지스터(TR10)가 오프되어 있으므로 전원단자(B+)의 전원이 저항(R11)을 통해 트랜지스터(TR11)의 베이스에 저전위 신호가 인가되어 제2데크테이프선택스위치(SW10)의 선택단자(Cro2), (NOR)의 선택에 따라 트랜지스터(TR11)가 온 및 오프되나 제1데크헤드(DH1)에서 재생되는 신호에는 영향을 미치지 못하게 되고, 이때 재생중인 제1데크에 내장된 테이프가 일반테이프일 경우에는 제1데크테이프감지스위치(SW11)가 단락되어 전원단자(B+)의 전원이 저항(R12) 및 그 스위치(SW11)를 통해 트랜지스터(TR12)의 베이스에 인가되므로 그가 온되고, 이에따라 전원단자(B+)의 전원이 저항(R13) 및 트랜지스터(TR12)를 통해 접지되어 트랜지스터(TR13)가 오프되므로 트랜지스터(TR14)도 오프되고, 이에따라 이퀄라이저증폭기(10)의 입력단자(EI)에 저전위신호가 인가되므로 제1데크헤드(DH1)에서 재생되는 신호는 그에따라 보상증폭된 재생신호로 출력되게 한다.When power is supplied to the power supply terminal (B + ) and continuous playback is performed, that is, the recording / playback selection switch (SW 3 ) is short-circuited to the playback selection terminal (PB 1 ) and the play buttons of the first and second decks. When the first deck playback switch SW 1 and the second deck recording / playback switch SW 2 are shorted by pressing, the recording / playback selection switch SW 3 is shorted to the playback selection terminal PB 1 . As (TR 4 ) (TR 5 ) is turned off and the first deck regeneration switch SW 1 is short-circuited, the power of the power supply terminal B + is supplied to the first deck driving motor through the switch SW 1 . It is applied to M 1 ) to drive it and to the base of the transistor TR 1 through the resistor R 1 , but because the low potential signal is applied to its collector, he is turned off, and the power supply terminal B + power source resistance (R 2) (R 3) is applied to the base of the transistor (TR 2) through again and he turned on, and the second deck melted in the / Reproducing switch (SW 2) is because it is on the power supply terminal (B +) power is applied through a resistor (R 4) to the base of the transistor (TR 3) of he turned on and thus the power of the power supply terminal (B +) Since it is grounded through this resistor R 7 and transistors TR 2 and TR 3 , a low potential signal is applied to the base of transistors TR 6 and TR 10 so that it is turned off, thereby turning the second deck driving motor ( Since M 2 ) is not driven and the transistor TR 10 is turned off, a low potential signal is applied to the base of the transistor TR 11 through the resistor R 11 through the power supply of the power supply terminal B + . The transistor TR 11 is turned on and off depending on selection of the selection terminals Cro 2 and NOR of the second deck tape selector switch SW 10 , but does not affect the signal reproduced by the first deck head DH 1 . If the tape embedded in the playing first deck is regular tape, the first deck tape Detection switch (SW 11) is short-circuited power supply terminal (B +) power resistor (R 12) and through the switch (SW 11) so applied to the base of the transistor (TR 12) of and he came, yiettara power supply terminal ( Since the power supply of B + ) is grounded through the resistor R 13 and the transistor TR 12 to turn off the transistor TR 13 , the transistor TR 14 is also turned off. Accordingly, the input terminal EI of the equalizer amplifier 10 is applied. Since a low potential signal is applied to the signal, the signal reproduced by the first deck head DH 1 is output as a compensation-amplified reproduction signal accordingly.

그리고, 재생중인 제1데크에 내장된 테이프가 크롬산화물 테이프일 경우에는 상기와 반대로 제1데크테이프감지스위치(SW11)가 개방되어 전원단자(B+)의 전원이 저항(R13)을 통해 트랜지스터(TR13)의 베이스에 인가되므로 그가 온되고, 이에따라 트랜지스터(TR14)의 베이스전류가 흐르게 되어 그가 온되므로 전원단자(B+)의 전원이 트랜지스터(TR14) 및 저항(R17)(R18)을 통해 이퀄라이저증폭기(10)의 입력단자(EI)에 고전신호로 인가되고, 이에따라 이퀄라이저증폭기(10)는 제1데크헤드(DH1)에서 재생되는 신호를 그에따라 보상증폭된 신호로 출력되게 한다.In addition, when the tape embedded in the first deck being regenerated is chromium oxide tape, the first deck tape detection switch SW 11 is opened in reverse to the above, so that the power of the power supply terminal B + is supplied through the resistor R 13 . It is applied to the base of the transistor TR 13 so that it is turned on. Accordingly, the base current of the transistor TR 14 flows and is turned on so that the power source of the power supply terminal B + is supplied to the transistor TR 14 and the resistor R 17 ( R 18 ) is applied as a high signal to the input terminal EI of the equalizer amplifier 10, and accordingly, the equalizer amplifier 10 converts a signal reproduced from the first deck head DH 1 into a compensation-amplified signal accordingly. Causes output

이와같은 상태에서 제1데크의 재생이 완료되어 제1데크재생스위치(SW1)가 개방되면, 제1데크구동모타(M1)의 구동이 정지되고, 트랜지스터(TR1)(TR2)가 오프되어 트랜지스터(TR3)도 오프되고, 즉, 트랜지스터(TR2)(TR5)가 오프됨에 따라 전원단자(B+)의 전원이 저항(R7)(R8)을 통해 트랜지스터(TR6)(TR10)의 베이스에 인가되어 트랜지스터(TR6)(TR10)가 온되어 제2데크구동모타(M2)를 구동시키게되고, 제2데크는 정상재생을 하게됨과 아울러 상기에서 트랜지스터(TR10)가 온되어 있으므로 전원단자(B+)의 전원이 저항(R11) 및 트랜지스터(TR10)를 통해 접지되어 트랜지스터(TR11)가 오프된다.In this state, when the regeneration of the first deck is completed and the first deck regeneration switch SW 1 is opened, the driving of the first deck driving motor M 1 is stopped, and the transistors TR 1 (TR 2 ) are stopped. is turned off transistor (TR 3) is also turned off, that is, the transistor (TR 2) (TR 5) the power that the resistance of the power supply terminal (B +) as off (R 7) transistor via (R 8) (TR 6 (TR 10 ) is applied to the base of the transistor (TR 6 ) (TR 10 ) is turned on to drive the second deck driving motor (M 2 ), the second deck is a normal regeneration and the transistor ( Since TR 10 is on, the power supply of the power supply terminal B + is grounded through the resistor R 11 and the transistor TR 10 so that the transistor TR 11 is turned off.

따라서 이때 제2데크테이프선택스위치(SW10)를 크롬산화물선택단자(Cro2)에 단락시키면 전원단자(B+)의 전원이 그 선택스위치(SW10)의 선택단자(Cro2) 및 다이오드(C10), 저항(R14), 다이오드(D11)를 통한 후 저항(R17)(R18)을 통해 이퀄라이저증폭기(10)의 입력단자(EI)에 고전위신호로 입력되므로 제2데크헤드(DH2)에서 재생되는 신호는 크롬산화물 테이프 기능에 따라 보상증폭된 재생신호로 출력되며, 상기에서 제2데크테이프선택스위치(SW10)를 일반선택단자(NOR)에 단락시킬 경우에는 상기 트랜지스터(TR11)의 온, 오프에 관계없이 다이오드(D10), 전원단자(B+)의 전원이 인가되지 않아 그가 차단되어 이퀄라이저증폭기(10)의 입력단자(EI)에 저전위신호가 입력되므로 제2데크헤드(DH2)에서 재생되는 신호는 일반테이프 기능에 따라 보상증폭된 재생신호로 출력되게 한다.Therefore, when the second deck tape selector switch SW 10 is shorted to the chromium oxide selector terminal Cro 2 , the power of the power supply terminal B + is selected from the selector terminal Cro 2 and the diode of the selector switch SW 10 . C 10 ), the second deck is input to the input terminal (EI) of the equalizer amplifier 10 through the resistor (R 14 ), after the diode (D 11 ) through the resistor (R 17 ) (R 18 ). The signal reproduced by the head DH 2 is output as a compensation-amplified reproduction signal according to the function of chromium oxide tape, and when the second deck tape selection switch SW 10 is shorted to the general selection terminal NOR, Regardless of whether the transistor TR 11 is turned on or off, the power of the diode D 10 and the power supply terminal B + is not applied and the low voltage signal is input to the input terminal EI of the equalizer amplifier 10. since the signal to be reproduced at the second deck heads (DH 2) is compensated according to the normal tape playback amplifying function It causes the output arcs.

이상에서 설명한 바와 같이 본 고안은 이퀄라이저증폭기 한개를 사용하여 연속재생되는 더블 데크 카세트에 있어서 제1데크가 일반테이프 및 크롬산화물, 메탈 테이프 기능으로 재생될 경우에 제2데크테이프선택스위치의 선택에 관계없이 재생되게 하여 제1데크의 재생이 완료되면, 제2데크의 테이프 기능이 선택에 따라 자동절활되게 함으로써 사용자가 편리하게 테이프 기능에 따른 최적의 재생을 청취할 수 있게 됨은 물론 제품에 대한 신뢰성이 향상되는 효과가 있다.As described above, the present invention relates to the selection of the second deck tape select switch when the first deck is reproduced by the normal tape, chromium oxide, and metal tape functions in a double deck cassette continuously reproduced using one equalizer amplifier. When the playback of the first deck is completed, the tape function of the second deck is automatically restored according to the selection so that the user can conveniently listen to the optimal playback according to the tape function, and the reliability of the product can be improved. There is an effect to be improved.
