The collector's connection point is connected to the base of transistor TR 2 via resistor R 3 and its emitter is recorded through second resistor D and M 2 through the resistor R 4 . To the collector of the transistor TR 2 connected to the < RTI ID = 0.0 > / playback switch SW 2, < / RTI > the recording signal input terminal REC has a resistor R 5 and R 6 respectively. Through transistor (TR 4) (TR 5) of the base and the transistor (TR 1) of the common-connected to the collector transistor (TR 5) of the emitter to the base resistance (R 7) a synchronized dubbing signal input terminal (SDI via ) through a transistor (TR 6) of connection to the collector, and the collector of the transistor (TR 5) is connected to a collector and a resistor (R 8) of said transistor (TR 2) resistance to the connection point (R 9) connected to the The collector is configured by connecting to the base of the transistor TR 7 connected to the second deck driving motor M 2. The recording and synchro dubbing signals are input to the recording and synchro dubbing signal input terminals REC (SDI), respectively. Is inputted, and the switch SW 1 (SW 2 ) is a switch short-circuited by pressing the play buttons of the first and second decks, and the reference numeral B + is a power supply terminal.
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, 제1 및 제2데크가 모두 구동 즉, 연속재생을 할 경우에는 녹음신호입력단자(REC) 및 싱크로 더빙 신호입력단자(SDI)에 모두 저전위신호가 인가되므로 트랜지스터(TR4)(TR5)(TR6)가 오프된다.When power is supplied to the power supply terminal B + and both the first and second decks are driven, that is, continuous playback, the low potential signal is applied to both the recording signal input terminal REC and the synchro dubbing signal input terminal SDI. Is applied, so the transistor TR 4 (TR 5 ) (TR 6 ) is turned off.
따라서 이때 제1데크 및 제2데크의 재생버튼을 눌러 제1데크재생스위치(SW1) 및 제2데크녹음/재생스위치(SW2)가 단락되면, 상기 제1데크재생스위치(SW1)가 단락됨에 따라 전원단자(B+)의 전원이 그 스위치(SW1)를 통해 제1데크구동모타(M1)에 인가되어 그가 구동됨과 아울러 저항(R1)(R2, R3)을 각각 통해 트랜지스터(TR1)(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 온되므로 전원단자(B+)의 전원이 저항(R8) 및 트랜지스터(TR2)(TR3)를 통해 접지되고, 이에 따라 트랜지스터(TR7)의 베이스에 저전위 신호가 인가되어 그가 오프되므로 제2데크구동모타(M2)는 구동되지 않게 된다.Therefore, when the first deck playback switch SW 1 and the second deck recording / playback switch SW 2 are short-circuited by pressing the playback buttons of the first and second decks, the first deck playback switch SW 1 is closed. As short-circuited, the power of the power supply terminal B + is applied to the first deck driving motor M 1 through the switch SW 1 to drive the same, and the resistors R 1 (R 2 and R 3 ) are respectively driven. It is applied to the base of the transistor TR 1 (TR 2 ) and is turned on, and since the second deck recording / regeneration switch SW 2 is turned on, the power supply of the power supply terminal B + is applied to the resistor R 4. Is applied to the base of the transistor TR 3 and is turned on so that the power supply of the power supply terminal B + is grounded through the resistor R 8 and the transistor TR 2 (TR 3 ), and thus the transistor TR The low-potential signal is applied to the base of 7 ) and is turned off so that the second deck driving motor M 2 is not driven.
이와같은 상태에서 제1데크의 재생이 완료되어 제1데크재생스위치(SW1)가 개방되면, 제1데크구동모타(M1)의 구동이 정지되고, 트랜지스터(TR1)(TR2)가 오프되어 트랜지스터(TR3)도 오프되므로 전원단자(B+)의 전원이 저항(R8)(R9)을 통해 트랜지스터(TR7)의 베이스에 인가되고, 이에 따라 트랜지스터(TR7)가 온되어 제2데크구동모타(M2)를 구동시키게 되고, 제2데크는 정상재생을 하게된다.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. Since the transistor TR 3 is turned off, the power supply of the power supply terminal B + is applied to the base of the transistor TR 7 through the resistor R 8 (R 9 ), and thus the transistor TR 7 is turned on. Then, the second deck driving motor (M 2 ) is driven, and the second deck is normally regenerated.
즉, 연속재생시 제1데크재생스위치(SW1) 및 제2데크녹음/재생스위치(SW2)가 단락되면, 제1데크가 먼저 재생을 하고 제1데크의 재생이 완료되면, 제2데크가 재생을 하게된다.That is, when the first deck playback switch SW 1 and the second deck recording / playback switch SW 2 are short-circuited during continuous playback, the first deck plays first , and when the first deck finishes playback, the second deck Will play.
그리고, 싱크로 더빙을 할 경우에는 상기와 반대로 녹음신호입력단자(REC) 및 싱크로 더빙 신호입력단자(SDI)에 모두 고전위 신호가 인가되므로 트랜지스터(TR4)(TR5)(TR6)가 온된다.In the case of synchronizing dubbing, since the high potential signal is applied to both the recording signal input terminal REC and the synchro dubbing signal input terminal SDI, the transistors TR 4 (TR 5 ) and TR 6 are turned on. do.
따라서 이때 녹음버튼을 눌러 제2데크녹음/재생스위치(SW2)가 단락되면, 전원단자(B+)의 전원이 그 스위치(SW2)를 통해 제2데크구동모타(M2)에 인가됨과 아울러 저항(R4)을 다시 통해 트랜지스터(TR3)의 베이스에 인가되므로 그가 온되나 트랜지스터(TR2)의 베이스에 저전위신호가 인가되어 트랜지스터(TR2)가 오프되므로 트랜지스터(TR3)도 오프되고, 이에 따라 전원단자(B+)의 전원이 저항(R8) 및 트랜지스터(TR5)(TR6)를 통해 접지되어 트랜지스터(TR7)의 베이스에 저전위 신호가 인가되므로 그가 오프되고, 이에따라 제2데크는 구동되지 않게되고, 잠시 대기상태로 있다가 제1데크재생스위치(SW1)가 단락되면, 전원단자(B+)의 전원이 그 스위치(SW1)를 통해 제1데크구동모타(M1)에 인가되어 그가 구동됨과 아울러 저항(R1)을 통해 트랜지스터(TR1)의 베이스에 인가되어 그가 온되고, 이에따라 녹음신호입력단자(REC)로 입력되는 고전위 신호는 저항(R6) 및 트랜지스터(TR1)를 통해 접지 및 저항(R5)을 통해 트랜지스터(TR4)의 베이스에 인가되므로 트랜지스터(TR5)는 오프되고, 트랜지스터(TR4)는 온되고 제1데크재생스위치(SW1)를 통한 전원단자(B+)의 전원이 저항(R2)및 트랜지스터(TR4)를 통해 접지되므로 트랜지스터(TR2)가 오프되고, 상기 트랜지스터(TR2)(TR5)가 모두 오프되어 전원단자(B+)의 전원이 저항(R8)(R9)을 통해 트랜지스터(TR7)의 베이스에 인가되므로 그가 온되고 이에따라 제2데크구동모타(M2)가 구동되고, 그 모타(M2)가 구동되면서 싱크로 더빙 작업을 실시하게 된다.Accordingly, when the second deck recording / playback switch SW 2 is shorted by pressing the record button, the power of the power supply terminal B + is applied to the second deck driving motor M 2 through the switch SW 2 . in addition, the resistance (R 4) back over so applied to the base of the transistor (TR 3) he is on, but is applied with the low potential signal to the base of the transistor (TR 2) the transistor (TR 2) is so-off transistor (TR 3) FIG. The power supply of the power supply terminal B + is thus grounded through the resistor R 8 and the transistors TR 5 and TR 6 so that a low potential signal is applied to the base of the transistor TR 7 so that it is turned off. Accordingly, when the second deck is not driven and is in the standby state for a while and the first deck regeneration switch SW 1 is short-circuited, the power supply of the power supply terminal B + is supplied to the first deck through the switch SW 1 . It is applied to the driving motor M 1 to drive it, and the transistor TR 1 through the resistor R 1 . The high potential signal is applied to the base of the power supply and is turned on, and accordingly, the high potential signal input to the recording signal input terminal REC is grounded through the resistor R 6 and the transistor TR 1 and the transistor TR through the resistor R 5 . 4 is applied to the base of the transistor TR 5 is turned off, the transistor TR 4 is turned on, and the power supply of the power supply terminal B + through the first deck regeneration switch SW 1 is supplied with the resistors R 2 and Since the transistor TR 4 is grounded, the transistor TR 2 is turned off, and the transistors TR 2 and TR 5 are all turned off so that the power supply of the power supply terminal B + is a resistor R 8 (R 9 ). Since it is applied to the base of the transistor (TR 7 ) through the second deck driving motor (M 2 ) is driven accordingly, and the motor (M 2 ) is driven to perform a synchro dub operation.
즉, 제1데크가 구동됨과 동시에 제2데크가 구동되어 싱크로 더빙 작업을 수행한다.That is, the first deck is driven and the second deck is driven to perform synchro dubbing.
이상에서 설명한 바와같이 본 고안은 사용자가 별도의 외부스위치 조작없이 제1데크 및 제2데크의 재생버튼을 누름에 따라 제1데크가 먼저 재생을 하고, 제1데크의 재생이 완료되면, 제2데크가 자동으로 재생되는 연속재생을 함으로써, 사용자가 번거로움없이 편리하게 사용할 수 있게 됨은 물론 간단한 회로의 구성으로 싱크로 더빙 작업도 수행할 수 있게되어 원가절감의 효과가 있게된다.As described above, according to the present invention, when the user presses the play buttons of the first deck and the second deck without a separate external switch operation, the first deck plays first, and when the first deck is played, the second deck is completed. By continuously playing the deck automatically, the user can use it conveniently without any hassle, and can also perform synchro dubbing with a simple circuit configuration, thereby reducing the cost.
