본 고안은 모타로 테이프를 주행시키면서 음성헤드로 음성신호를 녹음하는 녹음기에 관한 것으로, 특히 모타가 구동되지 않는 상태에서 음성신호가 입력되는 초기시간에 모타에 정속구동접압 이상의 전압을 인가하여 테이프를 빠른 시간내에 정속 구동시키게 한 녹음기의 모타 구동 제어회로에 관한 것이다.The present invention relates to a recorder for recording a voice signal with a voice head while driving a tape with a motor. In particular, a tape is applied by applying a voltage higher than the constant speed drive voltage to the motor at an initial time when the voice signal is input while the motor is not driven. It relates to a motor drive control circuit of a recorder which is driven at a constant speed within a short time.

종래의 녹음기회로는 제1도에 도시한 바와 같이 사용자가 녹음버튼을 눌러 녹음제어단자(REC)에 고전위신호가 입력되면, 전자스위치(SW1)가 단락되고, 모타구동전압출력부(1)의 출력전압은 모타(M)에 인가되어 그가 구동되면서 테이프를 주행시키며, 증폭기(2)에서 출력되는 음성신호는 음성헤드(2)에 인가되어 음성헤드(3)가 주행하는 테이프에 음성신호를 녹음하게 하였다.In the conventional recorder circuit, as shown in FIG. 1, when a user presses a record button to input a high potential signal to the record control terminal REC, the electronic switch SW 1 is short-circuited and the motor drive voltage output unit 1 is connected. The output voltage of) is applied to the motor M to drive the tape while it is driven, and the audio signal output from the amplifier 2 is applied to the voice head 2 so that the voice signal is applied to the tape on which the voice head 3 travels. To record.

그러나, 이와같은 녹음기회로는 증폭기(2)에서 음성신호가 출력되지 않아도 모타(M)는 계속 정속구동되면서 테이프를 정속주행시켜 음성헤드(3)가 녹음하게되므로 필요없이 전력을 소모함은 몰론 테이프의 소모량이 많은 결함이 있었다.However, such a recorder circuit consumes power without any need since the motor M is continuously driven at a constant speed while the voice head 3 is continuously recorded even though a voice signal is not output from the amplifier 2. There was a high consumption of defects.

본 고안은 이와같은 종래의 결함을 감안하여, 음성신호가 입력될 경우에만 모타를 구동시켜 테이프를 주행시킴은 물론 음성신호가 입력되는 초기의 일정시간동안 모타에 과전압을 인가하여 모타가 빠른시간내에 정속구동되면서 테이프를 주행시키게 안출한 것으로, 이를 첨부된 제2도의 도면에 의하여 상세히 설명하면 다음과 같다.The present invention, in view of the above-mentioned defects, drives the motor only when a voice signal is input, and drives the tape, and applies an overvoltage to the motor for a predetermined time during which the voice signal is input. It is designed to run the tape while driving at a constant speed, which will be described in detail with reference to the accompanying drawings of FIG.

제2도에 도시한 바와 같이 증폭기(2)의 출력신호를 녹음하는 음성헤드와(3)와 상기 증폭기(2)의 출력신호 및 기준전압(Vref)를 비교하는 비교기(4)와 상기 비교기(4)의 출력신호에 따라 펄스신호를 출력하는 리트리거러블 모노멀티(5)와 상기 리트리거러블 모노멀티(5)의 출력신호 및 기록제어단자(REC) 모드선택단자(MS)의 신호에 따라 제어신호를 출력하는 게이트부(6) 및 앤드화하는 앤드게이트(7)와 상기 앤드게이트(7)의 출력신호에 따라 펄스신호를 출력하는 모노멀티(8)와 상기 게이트부(6) 및 모노멀티(8)의 출력신호에 따라 모타구동 전압출력부(1)의 출력전압을 스위칭하는 전자스위치(SW1, SW2)로 된 스위칭부(9)와 상기 스위칭부(9)의 출력전압을 가산하여 모타(M)에 인가하는 가산기(10)로 구성한 것으로, 상기에서 게이트부(6)는 리트리거러블 모노멀티(5)의 출력신호와 녹음제어단자(REC) 및 모노선택단자(MS)의 신호가 모두 고전위신호이거나 또는 녹음제어단자(REC)는 고전위신호이고, 모드선택단자(MS)는 저전위신호일 때 고전위신호를 출력하게하고 전자스위치(SW2, SW3)는 그의 제어단자에 고전위신호가 인가될 때 단락되게 한다.As shown in FIG. 2, a voice head 3 recording the output signal of the amplifier 2 and a comparator 4 comparing the output signal and the reference voltage Vref of the amplifier 2 and the comparator ( According to the output signal of the retriggerable monomulti 5 and the output signal of the retriggerable mono multi 5 and the signal of the recording control terminal REC mode selection terminal MS according to the output signal of 4). A gate portion 6 for outputting a control signal, an AND gate 7 for activating and a monomulti 8 for outputting a pulse signal in accordance with an output signal of the AND gate 7 and the gate portion 6 and a mono The output voltage of the switching unit 9 and the switching unit 9 of the electronic switches SW 1 and SW 2 for switching the output voltage of the motor driving voltage output unit 1 in accordance with the output signal of the multi 8. It is composed of an adder 10 to be added to the motor (M), in which the gate portion 6 is a retriggerable mono-multi (5) When the output signal and the signals of the recording control terminal (REC) and the mono selection terminal (MS) are both high potential signals or the recording control terminal (REC) is a high potential signal, the mode selection terminal (MS) is a high potential signal. The signal is output and the electronic switches SW 2 and SW 3 are short-circuited when a high potential signal is applied to its control terminal.

이와같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention configured in this way in detail as follows.

사용자가 선택 녹음버튼을 눌러 모드선택단자(MS)로 고전위신호가 입력되고, 녹음버튼을 눌러 녹음제어단자(REC)로 고전위신호가 입력되면, 증폭기(2)의 출력신호가 음성헤드(3)에 입력됨과 아울러 비교기(4)의 반전입력단자(-)에 인가되고 이때 비교기(4)의 비반전입력단자(+)에 인가되는 기준전압(Vref)을 증폭기(2)에서 출력되는 음성신호의 크기보다 작게 설정하면, 증폭기(2)에서 음성신호가 출력될 경우에 비교기(4)에서 저전위신호가 출력되어 리트리거러블 모노멀티(5)의 트리거단자에 인가되므로 리트리거러블 모노멀티(5)의 출력단자에는 고전위신호가 출력되고, 그 출력된 고전위신호는 녹음제어단자(REC) 및 모드선택단자(MS)의 고전위신호와 함께 게이트부(6)에 입력되어 게이트부(6)는 고전위신호를 출력하고, 그 고전위신호는 전자스위치(SW2)의 제어단자에 인가되어 그가 단락된다.When the user presses the select recording button to input the high potential signal to the mode selection terminal (MS) and press the record button to input the high potential signal to the recording control terminal (REC), the output signal of the amplifier 2 is output to the audio head ( 3) and a voice output from the amplifier 2 to the reference voltage Vref applied to the inverting input terminal (-) of the comparator 4 and to the non-inverting input terminal (+) of the comparator 4 at this time. If it is set smaller than the size of the signal, when the audio signal is output from the amplifier 2, the low potential signal is output from the comparator 4 so that the trigger terminal of the retriable monomulti 5 is output. Since the high potential signal is output to the output terminal of the retriggerable monomulti 5, the output high potential signal is combined with the high potential signal of the recording control terminal REC and the mode selection terminal MS. Inputted to (6), the gate portion 6 outputs a high potential signal, and the high potential signal is applied to the control terminal of the electronic switch SW 2 and short-circuited it.

그리고, 이때 리트리거러블 모노멀티(5)에서 출력된 고전위신호가 녹음제어단자(REC) 및 모드선택단자(MS)의 고전위신호와 함께 앤드게이트(7)을 통해 모노멀티(8)에 입력되므로 모노멀티(8)는 고전위신호를 출력하여 전자스위치(SW3)도 단락된다.At this time, the high potential signal output from the retriggerable monomulti 5 is transmitted to the mono multi 8 through the AND gate 7 together with the high potential signal of the recording control terminal REC and the mode selection terminal MS. As it is input, the mono multi 8 outputs a high potential signal and the electronic switch SW 3 is also shorted.

따라서, 증폭기(2)에서 음성신호가 출력되는 초기시간에 스위치(SW2, SW3)는 모두 단락되어 모타구동전압출력부(1)의 출력단자(Q1, Q2)에서 출력되는 전압이 전자스위치(SW2, SW3)를 통해 가산기(10)에서 가산된후 모타(M)에 인가되어 모타(M)는 빠른 시간내에 정속구동되면서 테이프를 주행시키게 된다.Therefore, at the initial time when the audio signal is output from the amplifier 2, the switches SW 2 and SW 3 are all shorted so that the voltage output from the output terminals Q 1 and Q 2 of the motor driving voltage output unit 1 becomes short. After being added from the adder 10 through the electronic switches SW 2 and SW 3 , it is applied to the motor M so that the motor M is driven at a constant speed within a short time to drive the tape.

이와같은 상태에서 일정시간이 경과하여 모타(M)가 정속구동되고, 모노멀티(8)에서 저전위신호가 출력되어 스위치(SW3)가 개방되면, 모타구동전압출력부(1)의 출력단자(Q1)에서 출력된 정속구동전압만 전자스위치(SW2) 및 가산기(10)를 통해 모타(M)에 인가되어 모타(M)는 계속 정속구동된다.In this state, when a certain time has elapsed and the motor M is driven at constant speed, and the low potential signal is output from the mono multi 8 and the switch SW 3 is opened, the output terminal of the motor driving voltage output unit 1 is open. Only the constant speed drive voltage output from Q 1 is applied to the motor M through the electronic switch SW 2 and the adder 10 so that the motor M continues to be driven at constant speed.

이와같은 상태에서 증폭기(2)에서 음성신호가 출력되지 않으면, 비교기(4)는 그의 비반전입력단자(+)에 인가된 기준전압(Vref)에 의해 고전위신호를 출력하여 리트리거러블 모노멀티(5)의 트리거단자에 인가되므로 리트리거러블 모노멀티(5)는 저전위신호를 출력하여 게이트부(6) 및 앤드게이트(7)에 입력되므로 게이트부(6)는 저전위신호를 출력하여 전자스위치(SW2)가 단락되지 않고, 또한 앤드게이트(7)도 저전위 신호를 출력하여 모노멀티(8)가 저전위신호를 출력하고, 전자스위치(SW2)가 단락되지 않으므로 가산기(10)는 저전위신호를 출력하여 모타(M)가 구동되지 않는다.In this state, if no audio signal is output from the amplifier 2, the comparator 4 outputs a high potential signal by the reference voltage Vref applied to its non-inverting input terminal (+), thereby retriggerable monomulti. Trigger terminal of (5) Since the retriggerable monomulti 5 outputs a low potential signal and is input to the gate portion 6 and the end gate 7, the gate portion 6 outputs a low potential signal to the electronic switch SW 2 . Is not short-circuited, and the AND gate 7 also outputs a low potential signal, so that the multi-level 8 outputs a low potential signal, and the electronic switch SW 2 is not shorted. The motor M is not driven by outputting.

한편, 선택녹음버튼을 해제하여 모드선택단자(MS)로 저전위신호가 입력되고, 녹음버튼을 눌러 녹음제어단자(REC)로 고전위신호가 입력되면 게이트부(6)는 고전위신호를 출력하여 전자스위치가 단락되고, 앤드게이트(7) 및 모노멀티(8)는 모드선택단자(MS)의 저전위신호에 의해 저전위신호를 출력하여 전자스위치(SW3)가 단락되지 않으므로 모타구동전압출력부(1)의 출력단자(Q1)에서 출력된 정속구동전압만 전자스위치(SW2) 및 가산기(10)를 통해 모타(M)에 인가되어 모타(M)는 음성신호의 유무에 관계없이 정속구동되면서 테이프를 계속 주행시키게 된다.On the other hand, when the low potential signal is input to the mode selection terminal (MS) by releasing the selection recording button and the high potential signal is input to the recording control terminal (REC) by pressing the recording button, the gate unit 6 outputs a high potential signal. The electronic switch is short-circuited, and the AND gate 7 and the mono multi 8 output the low potential signal by the low potential signal of the mode selection terminal MS so that the electronic switch SW 3 is not shorted. Only the constant speed driving voltage output from the output terminal Q 1 of the output unit 1 is applied to the motor M through the electronic switch SW 2 and the adder 10 so that the motor M is related to the presence or absence of a voice signal. It runs at constant speed and keeps the tape running.

이상에서 설명한 바와같이 본 고안은 음성신호가 있을 경우에만 테이프를 주행시키므로 필요없이 테이프가 소모되는 것을 방지함은 몰론 음성신호가 입력되는 초기시간에 모타에 과전압을 인가하여 구동시키므로 테이프가 빠른 시간내에 정속주행하여 음성신호가 입력되는 초기시간에 테이프에 녹음되지 않는 것을 방지하는 효과가 있다.As described above, the present invention runs the tape only when there is a voice signal, thus preventing the tape from being consumed unnecessarily. Since the tape is driven by applying an overvoltage to the motor at an initial time when the voice signal is input, There is an effect of preventing the recording on the tape in the initial time when the audio signal is input by driving at constant speed.
