본 고안은 카셋트 라디오에 관한 것으로, 특히 AM방송신호를 창취하면서 FM방송신호를 녹음하거나 AM방송신호를 청취하면서 AM방송신호를 녹음할 수 있도록 된 모니터형의 카셋트 테이프 레코더에 관한 것이다.The present invention relates to a cassette radio, and more particularly, to a cassette type tape recorder of a monitor type capable of recording an FM broadcast signal while generating an AM broadcast signal or recording an AM broadcast signal while listening to an AM broadcast signal.
종래의 카셋트 라디오는 라디오튜너부의 출력신호가 메인앰프로 이퀄라이져를 거쳐 녹음되도록 되어 있으므로, 기능선택스위치로 AM이나 FM방송을 선택했을 때에는 스피커로는 해당 방송신호만 출력되고, 기능선택스위치로 테이프를 선택했을 때에는 녹음이나 재생기능을 실행시킬 수 있음과 더불어 방송신호를 테이프에 녹음시킬 수도 있었지마는, AM방송을 청취하면서 FM방송을 녹음하거나, 역으로 FM방송을 청취하면서 AM방송을 녹음할 수 있는 기능이 없는 단점이 있었다.In the conventional cassette radio, the output signal of the radio tuner unit is recorded through the equalizer as the main amplifier. When the AM or FM broadcast is selected with the function selection switch, only the corresponding broadcast signal is output through the speaker, and the tape is selected with the function selection switch. When you select it, you can run the recording or playback function, and you can record the broadcast signal on tape.You can record the FM broadcast while listening to the AM broadcast, or the AM broadcast while listening to the FM broadcast. There was a drawback of no function.
본 고안은 상기한 단점을 개선하기 위한 것으로, 종래의 회로에다 트랜지스터를 이용한 스위칭회로를 추가시키므로서 AM방송을 청취하면서 FM방송을 녹음시키거나 FM방송을 청취하면서 AM방송을 녹음시킬 수 있게되어 기능의 다양화는 이룩할 수 있도록 된 모니터형 카셋트 테이프 레코더를 제공함에 목적이 잇다.The present invention is to improve the above-mentioned disadvantages, by adding a switching circuit using a transistor in the conventional circuit, it is possible to record the FM broadcast while listening to the AM broadcast or AM broadcast while listening to the AM broadcast function The purpose of this diversification is to provide a monitored cassette tape recorder that can be achieved.
이하 본 고안의 구성 및 작용, 효과를 예시도면에 의거 상세히 설명하면 다음과같다.Hereinafter, the configuration, operation, and effects of the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 방송수신회로(1)와 녹음/재생회로(2) 및 오디오출력회로(3)로 이루어진 카셋트 테이프 회로더에 있어서, 방송수신회로(1)에 있는 중간주파증폭단(7)의 AM출력단과 멀티플렉서(8)의 FM출력단에다 연동으로 동작되는 기능선택스위치(SW1-1)(SW1-2)의 선택에 따라 동작하도록 트랜지스터(TR1∼TR8)와 저항(R1∼R4)으로 구성된 기능전환회로(4)를 매개하여 녹음재생회로(2)에 있는 이쿨라이져저앰프(10)의 입력단과 오디오 출력회로(3)의 입력단을 연결시킨 구조로 되어 있다.The present invention is a cassette tape circuit consisting of a broadcast receiving circuit (1), a recording / playback circuit (2), and an audio output circuit (3), wherein the AM output stage of the intermediate frequency amplifier stage (7) in the broadcast receiving circuit (1). And transistors TR 1 to TR 8 and resistors R 1 to R 4 to operate according to the selection of the function selection switch SW1-1 (SW1-2) operated in conjunction with the FM output terminal of the The input terminal of the equalizer amplifier 10 in the recording and playback circuit 2 is connected to the input terminal of the audio output circuit 3 through the configured function switching circuit 4.

제1도는 본 고안의 회로를 나타낸 것으로, 여기서 기능선택스위치(SW1-1)(SW1-2)의 각 단자(a)는 테이프, 단자(b)는 AM방송, 단자(c)는 AM모니터, 단자(e)는 FM모니터의 선택단자이고, 녹음/재생절환여동스위치(S1∼S6)는 도면에 접속된 녹음위치이고, 도면에 개방되어 있는 단자가 재생위치이다.1 shows a circuit of the present invention, wherein each terminal (a) of the function selection switch (SW1-1) (SW1-2) is a tape, the terminal (b) is an AM broadcast, the terminal (c) is an AM monitor, The terminal (e) is the selection terminal of the FM monitor, the recording / playback switching activation switches (S 1 to S 6 ) are the recording positions connected to the drawing, and the terminals opened in the drawing are the playback positions.
먼저 AM방송을 녹음시키면서 FM방송을 스피커(SP)(SP2)로 출력시키고자 한다면, 기능선택스위치(SW1-1)(SW1-2)를 단자(d)에 접속시키고 녹음재생절환스위치(S1∼S6)를 녹음위치인 현재 접속된 위치에 접속시킨다. 그러면 기능선택위치(SW1-1) 단자(d)를 통한 B+전원이 트랜지스터(TR1)(TR2)를 턴온시키게 되므로, 방송수신회로(1)의 중간주파증폭단(7)에서 출력되는 AM방송신호는 트랜지스터(TR1)(TR2) 및 콘덴서(C1)(C2), 스위티(C2)(C4), 이퀄라이져앰프(10), 다이오드(D1), 스위치(S5), 콘덴서(C3) 고역보상회로인 콘덴서(C5)와 저항(R5), 콘덴서(C5)와 코일(L1)을 차례로 통하여 헤드(HDR)에 의해 테이프에 녹음되어지게 된다. 또한 기능선택스위치(SW1-2)의 단자(d)를 통한 B+전원이 트랜지스터(Q5)(Q6)를 턴온시키게 되므로 방송수신회로(1)에 있는 멀티플렉서(8)에서 출력되는 FM방송신호의좌,우신호가 트랜지스터(Q5)(Q6)및 콘덴서(C7)(C8), 볼륨(VR1)(VR2), 메인앰프(11)를 차례로 통하여 스피커(SP1)(SP2)를 통해 외부로 송출되어진다. 이리하여 FM방송신호가 녹음/재생회로(2)에 위해 테이프에 녹음됨과 더불어 FM방송신호가 스피커(SP1)(SP2)를 통해 외부로 송출되어지는 것이다.First, if you want to output the FM broadcast to the speaker SP (SP 2 ) while recording AM broadcast, connect the function selection switch (SW1-1) (SW1-2) to the terminal (d), 1 to S 6 ) to the currently connected position as the recording position. Then, B + power supply via the function selection position (SW1-1) terminal (d) turns on the transistors TR 1 (TR 2 ), and thus the AM output from the intermediate frequency amplifier terminal 7 of the broadcast receiving circuit 1 The broadcast signal is a transistor (TR 1 ) (TR 2 ) and a capacitor (C 1 ) (C 2 ), a switch (C 2 ) (C 4 ), an equalizer amplifier (10), a diode (D 1 ), a switch (S 5 ). The capacitor (C 3 ) is recorded on the tape by the head (HDR) through the capacitor (C 5 ) and the resistor (R 5 ), the capacitor (C 5 ), and the coil (L 1 ). In addition, since the B + power supply via the terminal d of the function selector switch SW1-2 turns on the transistors Q 5 and Q 6 , the FM broadcast output from the multiplexer 8 in the broadcast reception circuit 1 is performed. left signal, Woosin call transistor (Q5) (Q 6) and a capacitor (C 7) (C 8), a volume (VR 1) (VR 2), the speaker through the main amplifier 11 in turn (SP1) (SP 2 It is sent out through). Thus, the FM broadcast signal is recorded on the tape for the recording / playback circuit 2, and the FM broadcast signal is transmitted to the outside through the speaker SP 1 and SP 2 .
이와 반대로 AM방송신호가 스피커(SP1)(SP2)를 통해 외부로 송출되고, FM방송신호가 헤드(HDR)(HDL)에 의해 테이프에 녹음되는 동작에 관해 설명하면, 이때는 기능선택스위치(SW1-1)(SW1-2)를 FM모니터위치인 단자(e)에 접속시킨다. 그러면 기능선택스위치(SW1-2)의 단자(e)를 통한 B+전원이 트랜지스터(TR7)(TR8)를 턴온시키게 되므로, 방송수신회로(1)에 있는 중간주파중폭단(7)에서 출력되는 AM방송신호가 트랜지스터(TR7)(TR8) 및 콘덴서(C7)(CP8), 볼륨(VR1)(VR2), 메인앰프를 차례로 통하여 스피커(SP1)(SP2)로 출력되어지고, 또한 기능선택스위치(SW1-1)의 단자(e)를 통한 B+전원이 트랜지스터(TR3)(TR4)를 턴온시키게 되므로 방송수신회로(1)에 있는 멀티플레서(8)에서 출력되는 FM방송신호의 좌,우신호가 트랜지스터(TR3)(TR4), 및 콘덴서(C1)(C2), 스위치(S2)(S4), 이퀄라이져앰프(10), 다이오드(D1)(D2), 스위치(S5)(S6), 콘덴서(C3)(C4), 고역봉상회로인 콘덴서(C5)와 저항(R5) 그리고 콘덴서(C6)와 저항(R6), 콘덴서(C5)와 코일(L1) 그리고 콘덴서(C6)와 코일(L2)를 차례로 통하여 헤드(HDR)(HDL)에 의해 테이프에 녹음되어진다. 이와 같이 AM방송신호가 스프커(SP1)(SP2)를 통해 외부로 송출됨과 더불어 FM방송신호가 녹음/재생회로(2)에 의해 테이프에 녹음되어지는 것이다.On the contrary, when the AM broadcast signal is transmitted to the outside through the speaker SP 1 (SP 2 ) and the FM broadcast signal is recorded on the tape by the head HDR (HDL), the function selection switch ( Connect SW1-1) (SW1-2) to the terminal (e) which is the FM monitor position. Then, B + power supply through the terminal e of the function selector switch SW1-2 turns on the transistors TR 7 (TR 8 ), so that at the intermediate frequency bandwidth stage 7 of the broadcast receiving circuit 1, The AM broadcast signal is output through the transistors TR 7 (TR 8 ), capacitors C 7 (CP 8 ), volume (VR 1 ) (VR 2 ), and main amplifier (SP 1 ) (SP 2 ). And the B + power supply via the terminal e of the function selector switch SW1-1 turns on the transistors TR 3 and TR 4 so that the multiplexer 8 in the broadcast reception circuit 1 is output. The left and right signals of the FM broadcast signal output from) are transistors TR 3 , TR 4 , and capacitors C 1 , C 2 , switches S 2 , S 4 , equalizer amplifier 10 and diodes. (D 1 ) (D 2 ), switch (S 5 ) (S 6 ), condenser (C 3 ) (C 4 ), condenser (C 5 ) and resistor (R 5 ) and condenser (C 6 ) Through resistor (R 6 ), capacitor (C 5 ) and coil (L 1 ), and then capacitor (C 6 ) and coil (L 2 ) The tape is recorded by the head HDR (HDL). Thus, it being AM broadcast signal are recorded on tape by a large soup (SP 1) the FM broadcasting signal recording / reproducing along as soon via (SP 2) transmitted to an external circuit (2).
위와같은 기능을 실행시키고자 할때에는 방송수신회로(1)에 의해 FM방송과 AM방송을 미리 선국해야한다.In order to execute the above functions, the FM and AM broadcasts should be tuned in advance by the broadcast receiving circuit (1).
상기한 바와 같이 본 고안은 스위칭 회로를 추가시키므로 써 AM방송을 청취하면서 FM방송을 녹음하거나, FM방송을 청취하면서 AM반송을 녹음시킬 수 있는 기능이 추가되어 보다 다양화된 카셋트 라디오를 실현시킬 수 있는 장점이 있다.As described above, the present invention adds a switching circuit so that the FM radio can be recorded while listening to AM broadcast, or the AM bounce can be recorded while listening to FM broadcast to realize more diversified cassette radio. There is an advantage.
