A first control unit, a selection switch unit which selects at least one of the plurality of switching elements to change the voltage supply logic of the first control unit, and is connected to at least one of the plurality of switching elements There is provided an automatic selection control circuit of a tape sound including a second control unit comprising a plurality of further switching elements for developing or outputting the operation of the connected switching element in accordance with a combination of a signal and a recording signal.
이하, 본 고안을 첨부도면에 의하여 상세히 설명한다.Hereinafter, the present invention will be described in detail by the accompanying drawings.
제 1 도는 본 고안에 따른 자동선택제어회로도로서, LA 7456M인 IC(1)를 사용한 것으로 IC(1)인 6번핀, 7번핀, 8번핀에 각각 제 1 제어부(2)의 트랜지스터(Q1)(Q2)(Q3)의 콜렉터측과 연결하고 같은 값을 갖는 저항 (R1)(R2)(R3)을 각각 거쳐 공급전원(Vcc)이 인가되도록 구성한다.FIG. 1 is an automatic selection control circuit diagram according to the present invention, which uses an IC 1 of LA 7456M. The transistor Q1 of the first control unit 2 is connected to pins 6, 7, and 8 of the IC 1, respectively. The power supply Vcc is configured to be connected to the collector side of Q2) (Q3) and applied via resistors R1, R2, and R3 having the same value.
본 고안에서의 저항(R1, R2, R3)은 2.4㏀으로 사용하였으며, 공급전원(Vcc)은 5V로 하였다. 트랜지스터(Q1)의 게이트에는 일측으로 저항(R4)을 통해 공급전원(Vcc)이 인가되고 다른 일측으로 저항(R4)을 통해 공급전원(Vcc)이 인가되고 다른 일측으로 다이오드(D1)를 통해 선택스위치(SW)의 단자(다)에 연결된다. 트랜지스터(Q2)의 게이트에는 일측으로 저항(R5)을 통해 공급전원(Vcc)이 인가되고 다른 일측으로 다이오드(D2)를 통해 선택스위치(SW)의 단자(나)에 연결된다. 트랜지스터(Q3)의 게이트에는 일측으로 저항(R6)을 통해 공급전원(Vcc)이 인가되고 다른 일측으로 다이오드(D3)를 통해 선택스위치(SW)의 단자(가)에 연결된다. 선택스위치(SW)의 후단은 접지시켜 선택되는 단자에 접지전위가 인가되도록 한다. 본 고안에서 저항(R4, R5)은 5.6㏀, 저항(R6)은 1.5㏀을 각각 사용하였다. 단자(가)는 스테레오 및 모노사운드 선택단자로 다중음성사운드일때 좌우채널이 예를들어 국어와 외국어가 따로 분리되어 오디오신호처리용 IC(도시하지 않음)에 출력되도록 제어하는 단자이며, 단자(나)는 다중음성사운드일때 좌우채널이 동시에 국어가 출력되도록하는 단자이며, 단자(다)는 다중음성사운드일때 좌우채널이 동시에 외국어가 출력되도록 하는 단자이다.In the present invention, the resistors R1, R2, and R3 were used as 2.4 kV, and the supply power source (Vcc) was 5V. Supply power Vcc is applied to the gate of transistor Q1 through resistor R4 on one side, supply power Vcc is applied through resistor R4 on one side, and selected through diode D1 on the other side. It is connected to the terminal (c) of the switch SW. The supply voltage Vcc is applied to the gate of the transistor Q2 through the resistor R5 on one side and connected to the terminal B of the selection switch SW through the diode D2 on the other side. The supply voltage Vcc is applied to the gate of the transistor Q3 through the resistor R6 on one side and connected to the terminal of the selection switch SW through the diode D3 on the other side. The rear end of the selection switch SW is grounded so that the ground potential is applied to the selected terminal. In the present invention, resistors R4 and R5 were 5.6 kV and resistor R6 was 1.5 kW, respectively. Terminal (A) is a stereo and mono sound selection terminal, which is a terminal that controls the left and right channels to be separately outputted to an audio signal processing IC (not shown), for example, when the left and right channels are separated from each other in multi-voice sound. ) Is a terminal that allows the left and right channels to be output simultaneously in multi-voice sound, and terminal (C) is a terminal that allows the left and right channels to be output in a foreign language simultaneously in multi-voice sound.
한편, 각각의 트랜지스터(Q1, Q2, Q3)의 에미터는 접지되어 있으며, 트랜지스터(Q3)의 콜렉터에는 다중음성신호/노말신호가 인가됨에 따라 온, 오프되는 트랜지스터(Q4)와 재생신호/기록신호가 인가됨에 따라 온, 오프되는 트랜지스터(Q5)가 직렬연결되어 접지되어 있는 제 2 제어부(3)가 연결된다. 여기서 노말신호는 스테레오 신호 및 모노신호를 의미한다. 또한, 선택스위치 (SW)의 단자(가)와 트랜지스터(Q5)의 베이스 사이에는 다이오드(D4)가 마련되어 기록모드시 단가(가)의 선택유무에 따라 트랜지스터(Q5)가 오프, 온되도록 한다.On the other hand, the emitters of the transistors Q1, Q2, and Q3 are grounded, and the transistor Q4 and the playback signal / recording signal which are turned on and off as the multiple audio signal / normal signal is applied to the collector of the transistor Q3. As is applied, the second control unit 3 which is turned on and off in series and connected to the ground is connected. Here, the normal signal means a stereo signal and a mono signal. In addition, a diode D4 is provided between the terminal A of the selection switch SW and the base of the transistor Q5 so that the transistor Q5 is turned off and on depending on whether the unit price is selected in the recording mode.
이와같이 구성되는 본 고안의 테이프사운드에 따라 자동선택제어회로의 동작을 (표1)을 참조하여 설명하면, 우선 초기의 선택스위치(SW)를 단자(가)에 두고 재생시의 스테레오사운드 및 모노사운드의 제어신호가 제어부(2)에 인가되면 제 1 제어부(2)의 트랜지스터(Q1, Q2)는 턴온, 트랜지스터(Q3)는 턴오프되며, 제 2 제어부(3)의 트랜지스터(Q4)가 턴오프, 트랜지스터(Q5)가 턴온되므로 IC(1)의 6번핀 및 7번핀에는 로우레벨, 8번핀에는 하이레벨이 인가되어 스테레오 및 모노동작을 하게된다. 한편, 선택스위치(SW)를 단자(나) 또는 단자 (다)에 두게되면 스테레오사운드일 경우 좌우채널이 믹싱되어 출력되게 된다.The operation of the automatic selection control circuit according to the tape sound of the present invention configured as described above will be described with reference to (Table 1). First, the initial selection switch (SW) is set to the terminal (a) for the stereo sound and the mono sound during reproduction. When the control signal is applied to the control unit 2, the transistors Q1 and Q2 of the first control unit 2 are turned on, the transistor Q3 is turned off, and the transistor Q4 of the second control unit 3 is turned off, Since transistor Q5 is turned on, a low level is applied to pins 6 and 7 of IC 1 and a high level is applied to pin 8 to perform stereo and mono operation. On the other hand, if the selection switch (SW) is placed in the terminal (b) or terminal (c), the left and right channels are mixed and output in the case of stereo sound.
또한, 재생시의 다중음성사운드신호가 제어부(2)에 인가되면 제 1 제어부(2)의 트랜지스터(Q1, Q2)는 턴온, 트랜지스터(Q3)는 턴오프되지만, 제 2 제어부(3)의 트랜지스터(Q4, Q5)가 턴온되므로 IC(1)의 6번핀, 7번핀 및 8번핀 모두에 로우레벨이 인가되어 좌우채널이 국어와 외국어가 따로 분리되는 동작을 하게 된다. 여기서, 국어만을 선택하여 듣고 싶을 경우는 선택스위치(SW)를 단자(나)에 놓게 되는데 이때 제 1 제어부(2)의 트랜지스터(Q2)가 오프되므로 IC(1)의 6번핀, 7번핀 및 8번핀 모두에 로우레벨이 인가되어 좌우채널이 국어와 외국어가 따로 분리되는 동작을 하게된다. 여기서, 국어만을 선택하여 듣고 싶을 경우는 선택스위치(SW)를 단자(나)에 놓게 되는데 이때 제 1 제어부(2)의 트랜지스터(Q2)가 오프되므로 IC(1)의 6번핀 및 8번핀에는 로우레벨, 7번핀에는 하이레벨이 인가되어 좌우채널이 국어만 선택되어 동작하게 된다. 외국어만을 선택하여 듣고 싶을 경우는 선택스위치(SW)를 단자(다)에 놓게 되는데 이때 제 1 제어부(2)의 트랜지스터(Q1)가 오프되므로 IC(1)의 6번핀에는 하이레벨, 7번핀 및 8번핀에는 로우레벨이 인가되어 좌우채널이 외국어만 선택되어 동작하게 된다.In addition, when the multi-sound sound signal during reproduction is applied to the control unit 2, the transistors Q1 and Q2 of the first control unit 2 are turned on and the transistor Q3 is turned off, but the transistors of the second control unit 3 ( Since Q4 and Q5 are turned on, a low level is applied to all of pins 6, 7 and 8 of the IC 1 so that the left and right channels are separated from the Korean and foreign languages. In this case, if only the Korean language is desired to be listened to, the selector switch SW is placed on the terminal (B). At this time, the transistor Q2 of the first control unit 2 is turned off, so pins 6, 7 and 8 of the IC 1 are turned off. Low level is applied to both burn pins so that the left and right channels are separated from Korean and foreign languages. In this case, if only the Korean language is desired to be heard, the selection switch SW is placed at the terminal (B). At this time, since the transistor Q2 of the first control unit 2 is turned off, the pins 6 and 8 of the IC 1 are low. Level, high level is applied to pin 7, so that only left and right channels are selected and operated. If only the foreign language is desired to be listened to, the selector switch SW is placed on the terminal C. At this time, the transistor Q1 of the first control unit 2 is turned off. Therefore, pin 6 of the IC 1 has a high level, pin 7 and Low level is applied to pin 8 so that only left and right channels are selected and operated.
기록시의 경우는 선택스위치(SW)가 어느 단자에 있더라도 스테레오 및 모노동작을 하게 된다.In the case of recording, stereo and mono operations are performed regardless of which terminal the selection switch SW is in.
이상 설명한 바와같이 본 고안에 따르면 선택스위치를 고정시킨 상태에서 스테레오사운드, 모노사운드, 다중음성사운드를 용이하게 청취할 수 있으며, 특히 다중음성사운드의 청취시 간단한 조작으로 원하는 음성을 선택할 수 있으므로 비디오테이프레코더나 캠코더에 적용해서 사용자들이 매우 편리하게 이용할 수 있는 효과가 있다.As described above, according to the present invention, the stereo switch, the mono sound, and the multi-sound sound can be easily listened while the selector switch is fixed. In particular, when the multi-sound sound is listened to, the desired voice can be selected by a simple operation. Applied to recorders or camcorders, there is an effect that users can use very conveniently.
