The transistor T is connected to the regeneration / recording selection switch SW 4 through the ground capacitor C 1 . Connected to the base axis of the collector, and the transistor (TR 3) of R 2) the collector of the transistor (TR 3) is connected to the base of the recording deck, a motor drive switch (SW 5) and the transistor (TR 4) and the transistor (TR The collector of 4 ) is configured by connecting the collector of the transistor TR 5 connected to the base via the resistor R 8 to the recording deck drive motor M 1. In the above, the automatic selection circuit 1 selects the music of the designated song. Upon completion, the low potential signal is output. The fast forward switch SW 3 is in a short circuit state when the relay RL 1 is driven, and the dubbing switches SW 21 and SW 22 are interlocked.
이와같이 구성한 본 고안의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured in this way as follows.
더빙녹음이 아닌 경우에는 더빙스위치(SW21),(SW22)가 그의 언더빙단자(U),(U')에 접속되어 있는 상태이므로 트랜지스터(TR3)의 베이스가 오픈상태에 있게되어 그가 오프되어, 녹음버튼을 누름에 따라 녹음데크의 모터구동스위치(SW5)가 온되게 되면 그 스위치(SW5)를 통해 트랜지스터(TR4)의 베이스에 고전위가 인가되어 그가 온되고, 이에따라 트랜지스터(TR5)가 온되어 그 트랜지스터(TR5)를 통해 녹음데크구동모터(M1)에 전원단자(B+)의 전원이 인가되어 모터(M1)가 구동함으로써 녹음작업을 실시하게 된다. 즉, 언더빙시에는 재생데크와 별도로 녹음데크가 구동되어 녹음작업을 수행한다.If the recording is not dubbed, the dubbing switches SW 21 and SW 22 are connected to their underdub terminals U and U ', so that the base of the transistor TR 3 is in an open state. When the motor drive switch SW 5 of the recording deck is turned on as the recording button is pressed, the high potential is applied to the base of the transistor TR 4 through the switch SW 5 , thereby turning on the transistor. (TR 5) is that the transistor (TR 5) the recording deck driven in the power supply of the power supply terminal (B +) to the motor (M 1) is applied via one is subjected to recording operation by driving the motor (M 1). That is, during the underdub, the recording deck is driven separately from the playback deck to perform recording.
이와같은 상태에서 재생데크와 녹음데크를 연동시켜 더빙작업을 실시하고자 더빙스위치(SW21),(SW22)를 더빙단자(D)(D')에 접속하고 재생/녹음선택스위치(SW4)를 녹음단자(R)에 접속하여 녹음데크모터 구동스위치(SW5)를 단락시키면 상기한 바와같이 스위치(SW5)를 통한 고전위에 의해 트랜지스터(TR4)가 온되고 트랜지스터(TR5)가 온되어 녹음데크 구동모터(M1)가 구동된다. 이때 상기 더빙스위치(SW22)를 통한 전원이 콘덴서(C1)에 충정되고, 이 충전전원이 트랜지스터(TR3)의 베이스에 인가됨에 따라 그 트랜지스터(TR3)가 온되며, 이에따라 트랜지스터(TR4)(TR5)가 오프되어 모터(M1)의 구동이 정지된다. 즉 콘덴서(C1)와 충전동안 모터(M1)가 구동되다가 중지된다.In such a state, in order to perform the dubbing operation by interlocking the playback deck and the recording deck, connect the dubbing switches (SW 21 ) and (SW 22 ) to the dubbing terminals (D) and (D '), and play / recording selection switch (SW 4 ). Is connected to the recording terminal R and the recording deck motor drive switch SW 5 is shorted, the transistor TR 4 is turned on by the high potential through the switch SW 5 and the transistor TR 5 is turned on as described above. The recording deck drive motor (M 1 ) is driven. At this time, the power through the dubbing switch (SW 22) and loyalty to the capacitor (C 1), the charging power becomes as applied to the base of the transistor (TR 3) the transistor (TR 3) on, yiettara transistor (TR 4 ) TR 5 is turned off to stop the driving of the motor M 1 . That is, the motor M 1 is driven and stopped during the charging of the capacitor C 1 .
이 상태가 더빙동시 시작상태가 되는 것이다. 이와같은 상태에서 자동선곡기능을 이용하여 재생테이프의 특정선곡을 지정한 후 재생스위치(SW1) 및 재생빨리감기 스위치(SW3)를 동시에 단락시키면, 트랜지스터(TR2)(TR3)의 베이스에 고전위가 인가되어 트랜지스터(TR2)(TR3)가 온상태에 있게되고 이에따라 트랜지스터(TR4)(TR5)가 계속 오프상태에 있어 모터(M1)도 정지상태 계속 유지하게 된다.This state becomes the dubbing start state. In this state, if the specific selection of the playback tape is specified using the automatic selection function, the playback switch SW 1 and the playback fast forward switch SW 3 are short-circuited at the same time to the base of the transistor TR 2 (TR 3 ). The high potential is applied so that the transistors TR 2 (TR 3 ) are in the on state, and accordingly the transistors TR 4 (TR 5 ) remain in the off state so that the motor M 1 remains in the stopped state.
이때 자동선곡도중 자동선곡회로(1)로부터 고전위가 출력되는 상태이므로 트랜지스터(TR1)가 온상태에 있고, 이에따라 릴레이(RL1)가 구동되어 상기 재생빨리감기 스위치(SW3)가 계속 단락상태에 있도록 한다.At this time, since the high potential is output from the automatic selection circuit 1 during the automatic selection, the transistor TR 1 is in an on state. Accordingly, the relay RL 1 is driven so that the fast rewind switch SW 3 is continuously shorted. To be in a state.
이와같은 상태에서 자동선곡이 완료되어 자동선곡회로(1)로부터 저전위신호가 출력되면 트랜지스터(TR1)가 오프되고, 이에따라 릴레이(RL1)가 오프되므로 스위치(SW3)가 개방되어 트랜지스터(TR3)의 베이스전위는 저전위로 되고, 계속 턴온 상태를 유지하고 있는 트랜지스터(TR2)에 의해 트랜지스터(TR4)가 오프되어 스위치(SW5)를 통한 전원이 트랜지스터(TR4)의 베이스에 인가되므로 그 트랜지스터(TR4)가 온되고 트랜지스터(TR5)가 온되어 녹음데크 구동모터(M1)가 구동되기 시작한다. 즉, 자동선곡이 완료됨과 동시에 녹음데크가 구동되어 동시더빙이 실행되는 것이다.In this state, when the automatic selection is completed and the low potential signal is output from the automatic selection circuit 1, the transistor TR 1 is turned off. Accordingly, the relay RL 1 is turned off, so that the switch SW 3 is opened to open the transistor ( The base potential of TR 3 becomes low and the transistor TR 4 is turned off by the transistor TR 2 that is continuously turned on so that the power supply through the switch SW 5 is applied to the base of the transistor TR 4 . Since the transistor TR 4 is turned on and the transistor TR 5 is turned on, the recording deck driving motor M 1 starts to be driven. In other words, as soon as the automatic selection is completed, the recording deck is driven to perform simultaneous dubbing.
이상에서 설명한 바와같이 본 고안은 자동선곡기능을 갖는 더블 데크 카세트의 자동선곡회로(1)의 출력신호에 의해 녹음데크 구동모터(M1)를 구동함으로써 간단용이하게 동시더빙 작업을 수행할 수 있는 효과가 있게 된다.As described above, the present invention can easily perform simultaneous dubbing operation by driving the recording deck drive motor M 1 by the output signal of the automatic selection circuit 1 of the double deck cassette having the automatic selection function. It will work.
