본 고안은 더빙(Dubbing)기능을 가진 더블 데크에 있어, 녹음 입력신호를 자동적으로 전환선택하여 이를 표시할수 있도록 한 더빙기능 데크의 입력 자동전환회로에 관한 것이다.The present invention relates to an input automatic switching circuit of a dubbing function deck in which a double deck having a dubbing function can automatically select and display a recording input signal.
종래에는 더빙을 하고자 할 경우에 반드시 더빙스위치를 온 시켜야만 하는데 사용자의 부주위로 연하여 온시키지 않았을 경우에는 라인입력 신호가 정속 또는 배속상태로 녹음 되기도 하였으며, 또한 더빙스위치를 온시킨 상태에서는 더빙이 되지 않고, 라인 입력신호만 녹음 되는등 사용 조작상에 많은 불편이 있었다.Conventionally, if you want to dub, you must turn on the dub switch, but if you do not turn on due to the user's surroundings, the line input signal may be recorded at constant speed or double speed. However, there was a lot of inconvenience in using the operation such as recording only the line input signal.
본 고안은 이러한 점을 감안하여 더빙시키고자 할 경우에는 녹음암프의 입력으로 재생테크의 출력신호가 선택되도록 하고, 더빙상태가 아닐경우에는 세트의 외부로 부터의 라인(Line) 입력신호가 선택되도록 자동전환시킴과 동시에 그의 동작상태를 해당표시기의 점등상태로서 간편하게 표시할 수도 있도록 안출한 것으로서, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention allows the output signal of the playback technology to be selected as the input of the recording amp when dubbing in consideration of this point, and the line input signal from the outside of the set is selected when the dubbing state is not selected. At the same time, the automatic switching and the operation state of the display as a light state of the indicator can be displayed easily, and described in detail by the accompanying drawings as follows.
라인 입력신호 단자(IN1)와 재생출력 신호입력단자(IN2)의 신호를 스위칭 하는 각각의 아날로그스위치(AS1),(AS2)의 제어단자(C1),(C2)중 단자(C1)에는 트랜지스터(Q3)를 통하여 녹음스위치(SW1)의 단자(R)에 접속된 발광소자(LED3)를 접속하고, 단자(C2)에는 콜렉터측이 상기 트랜지스터(Q3)의 베이스에 접속된 트랜지스터(Q2)의 베이스와 트랜지스터(Q1)의 에미터측을 접속하고, 재생스위치(SW3)가 베이스에 접속된 트랜지스터(Q1)의 콜렉터에 각각 발광소자(LED1),(LED2)를 연결하여 더빙시 속도선택스위치(SW3)의 고속, 정속단자(H),(L)에 연결하여 구성시킨다.Terminals of the control terminals C 1 and C 2 of the respective analog switches AS 1 and AS 2 for switching the signals of the line input signal terminal IN 1 and the reproduction output signal input terminal IN 2 . The light emitting element LED 3 connected to the terminal R of the recording switch SW 1 is connected to the C 1 through a transistor Q 3 , and the collector side of the transistor Q 3 is connected to the terminal C 2 . The base of the transistor Q 2 connected to the base of the transistor and the emitter side of the transistor Q 1 are connected, and the light emitting element LED is respectively connected to the collector of the transistor Q 1 connected to the base of the regeneration switch SW 3 . 1 ), (LED 2 ) by connecting to the high speed, constant speed terminal (H), (L) of the speed selection switch (SW 3 ) when dubbed.
미설명 부호 Vcc는 직류전원, A는 공지의 녹음암프, OUT는 녹음 출력단자. R1-R5는 저항이다.Vcc is the DC power supply, A is the well-known recording amp, and OUT is the recording output terminal. R 1 -R 5 are resistors.
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
먼저, 정속으로 더빙시키고자 할경우에는 속도 선택스위치(SW2)를 정속측(L)으로 전환시킨후, 녹음데크의 녹음버턴을 누르게 되면, 녹음스위치(SW1)가 단자(R),(C) 접속상태로 되고, 재생테크의 재생버턴을 누르면 이에 따라 스위치(SW3)가 온상태가 된다.First, to dub at constant speed, switch the speed selector switch (SW 2 ) to the constant speed side (L), and then press the recording button on the recording deck.The recording switch (SW 1 ) is connected to the terminal (R), ( C) The connection state is entered, and when the regeneration button of the regeneration tech is pressed, the switch SW 3 is turned on accordingly.
이와 같은 상태에서는 직류전원(Vcc)이 스위치(SW1)의 단자(C),(R) →스위치(SW2)의 단자(C),(L)→발광소자(LED2)의 애노우드측의 순으로 공급되며, 또한 직류전원(Vcc)이 재생스위치(SW3) 및 저항(R3)을 통하여 트랜지스터(Q1)의 베이스에 가해져 트랜지스터(Q1)를 도통시키게 되므로 상기한 발광소자(LED2)는 턴온됨과 동시에 트랜지스터(Q1)의 에미터측이 하이상태로 되어 트랜지스터(Q2)가 도통 되므로 그의 콜렉터 전위는 로우 상태가 된다.Such a state, the DC power supply (Vcc) a switch (SW 1) of the terminal (C), (R) → switch (SW 2) of the terminals (C), (L) → the light emitting device (LED 2) of the anode side In addition, since the DC power supply (Vcc) is applied to the base of the transistor (Q 1 ) through the regeneration switch (SW 3 ) and the resistor (R 3 ) to conduct the transistor (Q 1 ), the light emitting device ( LED 2 ) is turned on and at the same time the emitter side of transistor Q 1 becomes high and transistor Q 2 conducts, so its collector potential is low.
따라서, 트랜지스터(Q3)의 베이스 전위도 로우상태가 되어 부도통 되므로 발광소자(LED3)의 애노우드측에 직류전원(Vcc)이 가해지더라도 발광소자(LED3)는 턴온되지 못한다.Thus, the transistor is the base potential is also low level of (Q 3) default barrel, so the light emitting element, even if the direct-current power supply (Vcc) applied to the anode side of the (LED 3) the light emitting device (LED 3) does not turn on.
또한, 트랜지스터(Q1)의 에미터 하이신호는 아날로그스위치(AS2)의 제어단자(C2)에 가해져서 온 되므로, 재생데크로 부터의 재생출력이 입력되는 단자(IN2)신호를 녹음암프(A)에 가해주므로 그의 출력단자(OUT)에는 재생출력이 나타나는 정속 더빙상태가 된다.In addition, since the emitter high signal of the transistor Q 1 is applied to the control terminal C 2 of the analog switch AS 2 , the signal of the terminal IN 2 to which the reproduction output from the reproduction deck is input is recorded. Since it is applied to the amp A, its output terminal OUT is in a constant speed dubbing state in which the reproduction output appears.
한편, 고속더빙시에는 상기한 정속더빙시와 비교하여 스위치(SW2)가 단자(C),(H) 접속상태로 전환되는 것만이 상이하고, 그밖에 회로동작상태는 동일한 것이다.On the other hand, in the case of high speed dubbing, only the switch SW 2 is switched to the terminal C and H connection states compared with the above-described constant speed dubbing, and the circuit operation state is the same.
즉 이경우에는 발광소자(LED1)가 턴온되어 고속더빙상태 임을 알려주게 된다.That is, in this case, the light emitting device LED 1 is turned on to inform that it is in a high speed dubbing state.
한편, 외부라인 입력신호를 녹음시키고자 할 경우에는 재생데크는 동작시키지 않고, 녹음데크의 녹음버턴만을 눌러주면 되는데 이와 같은 상태에서느 스위치(SW1)의 단자(C),(R)가 접속되고, 스위치(SW3)는 재생데크의 정지로 오프상태가 된다.On the other hand, if you want to record the external line input signal, do not operate the playback deck, but only press the recording button of the recording deck. In this state, the terminals (C) and (R) of the switch (SW 1 ) are connected. The switch SW 3 is turned off by stopping the playback deck.
따라서, 트랜지스터(Q1)의 베이스 전위는 로우상태로 되어 트랜지스터(Q1)는 오프되므로 그의 에미터 전위는 로우상태가 되어 트랜지스터(Q2)는 오프되므로 그의 콜렉터 전위는 하이상태가 되어 트랜지스터(Q3)가 도통된다.Therefore, since the base potential of the transistor Q 1 goes low and the transistor Q 1 turns off, its emitter potential goes low and the transistor Q 2 turns off, so that its collector potential goes high, so that the transistor ( Q 3 ) is conducted.
이와 같이 트랜지스터(Q3)가 도통되면 직류전원(Vcc)이 스위치(SW1)의 단자(C),(R)를 통하여 발광소자(LED3)및 트랜지스터(Q3)의 순으로 가해지므로 이때에는 발광소자(LED3) 턴온되어 외부라인 신호를 녹음중인 상태임을 알려주게 된다.As described above, when the transistor Q 3 is conducted, the DC power supply Vcc is applied in the order of the light emitting element LED 3 and the transistor Q 3 through the terminals C and R of the switch SW 1 . The light emitting device (LED 3 ) is turned on to inform that the state of recording the external line signal.
또한 트랜지스터(Q1)의 에미터측은 로우신호 상태가 되어 아날로그 스위치(AS2)는 오프되고, 이경우에는 트랜지스터(Q3)의 베이스측의 하이신호가 아날로그스위치(AS1)의 제어단자(C1)에 가해져 아날로그스위치(AS1)를 도통시키므로 라인입력 신호단자(IN1)에 입력되는 외부신호가 녹음암프(A)에 가히저셔 그의 출력단자(OUT)에 녹음신호가 나타나게 되는 것이다.In addition, the emitter side of the transistor Q 1 is in a low signal state and the analog switch AS 2 is turned off. In this case, the high signal at the base side of the transistor Q 3 is controlled by the control terminal C of the analog switch AS 1 . 1 ) is applied to the analog switch AS 1 so that the external signal input to the line input signal terminal IN 1 is applied to the recording amplifier A so that the recording signal appears at its output terminal OUT.
이와 같이 동작하는 본 고안은 더빙상태에서는 녹음암프의 입력이 재생출력신호가 가해지도록 자동전환 시키고, 외부신호를 녹음하고자 할때에는 자동적으로 녹음암프의 입력이 라인입력신호가 가해지도록 전환시킬뿐 아니라 해동동작상태를 발광소자로서 용이하게 식벽되도록 표시함으로서 사용상 매우 편리한 이점이 있는 것이다.The present invention operates as described above, in the dubbing state, the input of the recording amp is automatically switched so that the playback output signal is applied. By displaying the operation state to be easily walled as a light emitting device there is a very convenient advantage in use.
