재생데크의 재생출력이 입력되는 증폭이(A1)와 다이오드(D1,D2)로 재생출력 여부를 검출하는 재생검출부(가) 출력은 트랜지스터(TR2)지연회로(R8,C5)로 곡의 끝부분을 검출하는 곡 끝 검출부(나)입력에 연결하고, 곡 끝 검출부(나)의 트랜지스터(TR2) 콜렉터는 트랜지스터(TR1,TR13)와 스취치(SW1-1,SW2-1,SW6)로 된 더빙시 페이드 인을 수행하는 페이드 인 구동 제어부(다)에 연결함과 동시에 트랜지스터(TR3)와 지연회로(R10,C4)로 곡의 시작부분을 검출하는 곡 시작 검출부(라) 입력에 연결하며, 곡 시작검출부(라)의 출력은 페이드 인, 아웃 장치(마)의 페이드인 단지(IN)에 콜렉터가 연결되고 애미터는 트랜지스터(TR4) 베이스에 연결하며 페이드 인, 아웃장치(마)의 페이드 아웃단자(OUT)에 콜랙터가 연결되고 에미터는 접지된 트랜지스터(TR5)베이스는 곡 끝 검출부(나)의 출력에 연결함과 동시에 모터 제어부(바)입력에 연결하되, 모터 제어부(바)는 재생데크모터(M1)를 제어하는 트랜지스터(TR13,TR6)와 녹음데크모터(M-)를 제어하는 트랜지스터(TR7,TR12) 및 트랜지스터(TR5,TR12)에 제어신호를 입력시키는 플립플롭을 구성하는 NAND게이트(G1,G2)와 NAND게이트(G1,G2) 일측에 각각 제어신호을 입력시키는 트랜지스터(TR8~TR11)로 구성하여 페이드 인, 아웃 시에 모터를 제어 구동토록 하여서 된 더블 카세트 테이크 레코더의 자동 페이드 인 더빙 제어장치.The reproducing detector (A), which detects whether the regeneration output is inputted by the amplification (A 1 ) and the diodes (D 1 , D 2 ) to which the regeneration output of the regeneration deck is input, has a transistor (TR 2 ) delay circuit (R 8 , C 5). ) in connection with the song end detector (B) for detecting the input end of the song, and the transistor (TR 2), the collector end of the track detector (B) is a transistor (TR 1, TR 13) and scale chwichi (SW 1-1 , SW 2-1, SW 6 ) is connected to the fade in driving control unit (C) which performs fade in during dubbing and at the same time the beginning of the song with the transistor TR 3 and the delay circuits R 10 and C 4 . Is connected to the input of the song start detector (D), and the output of the song start detector (D) is connected to the in (IN) of the fade in and out devices (e) and the collector is connected to the transistor (TR 4). Is connected to the base, and the collector is connected to the fade out terminal (OUT) of the fade in and out device (e), and the emitter is grounded (TR 5 ) base. Is connected to the output of the song end detector (b) and at the same time to the motor control (bar) input, the motor control (bar) is recording with the transistors (TR 13, TR 6 ) for controlling the reproduction deck motor (M 1 ) NAND gates G 1 and G 2 and NAND gates constituting a flip-flop for inputting control signals to the transistors TR 7 and TR 12 controlling the deck motor M and the transistors TR 5 and TR 12 . G 1 , G 2 ) Automatic fade in dubbing control device of a double cassette take recorder composed of transistors (TR 8 to TR 11) for inputting control signals to one side so as to control and drive the motor at fade in and out. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
