본 고안은 더블데크카셋트의 모우터제어회로에 관한 것으로, 특히 A데크의 테이프내용을 B데크의 테이프로 더빙(Dubbing)시킬 때 정속 및 고속이외에 중속으로도 더빙시킬 수 있게 해줌으로써 중속더빙에 의해 복사기능을 수행하면서 더빙되는 내용에 관한 모니터음을 청취할 수 있도록 된 더블데크카세트의 모우터제어회로에 관한 것이다.The present invention relates to a motor control circuit of a double deck cassette. In particular, when dubbing the contents of A deck tape with the tape of B deck, it is possible to dub at medium speed in addition to the constant speed and high speed. The present invention relates to a motor control circuit of a double deck cassette capable of listening to a monitor sound regarding a dubbed content while performing a copy function.

종래의 더블데크카세트에서는 통상 A데크에서 B데크로 테이프내용을 더빙시키기는 경우 테이프에 기록된 내용을 정상적으로 청취해가면서 더빙시킬 수 있도록 모우터를 정속으로 구동시키는 정속제어와, 이 정속제어보다 고속(배속)으로 모우터를 구동시키면서 더빙시키는 고속제어를 통해 실시하도록 되어 있는 바, 여기서 고속의 더빙시에는 이퀼라이저 증폭기 및 헤드특성상 가청주파수의 하이측 보상문제가 난제로 되고 있다. 즉, 그 일례로서 회화테이프의 내용을 고속으로 더빙시킬 때 청취자는 테이프의 내용이 고속으로 더빙됨으로 말미암아 그 내용에 대한 모니터음을 알아듣기 어렵게 되므로 고속의 더빙시에는 단지 복사기능만 실시되는 것으로 되어 소정의 신호에 대한 더빙상태를 청취하면서 더빙시킬 수 없다는 단점이 있었다.In the conventional double deck cassette, when dubbing the contents of the tape from the A deck to the B deck, the constant speed control which drives the motor at a constant speed so that the contents recorded on the tape can be dubbed while listening to the normal contents, and faster than the constant speed control. The high-speed control of dubbing while driving the motor at (double speed) is performed. In this case, the high-side compensation problem of the audible frequency is difficult due to the equalizer amplifier and the head characteristics. That is, as an example, when the contents of the conversation tape are dubbed at high speed, it is difficult for the listener to hear the monitor sound of the contents because the contents of the tape are dubbed at high speed, so only the copy function is performed at the high speed dubbing. There is a disadvantage in that the dubbing cannot be performed while listening to a dubbing state for a predetermined signal.

본 고안은 상기한 단점을 개선시키기 위해서 고안된 것으로, 모우터의 속도를 정속 및 고속으로 제어할 수 있게 됨과 더불어 모우터를 정속과 고속의 중간속도로도 구동시킬 수 있도록 구성해서, A데크에서 B데크로 테이프의 내용을 고속으로 더빙시킬때에는 고속복사만 실행시키는 한편 모니터로 출력되는 신호는 뮤팅시킬수 있게 해주고, 중속으로 더빙시킬 때에는 사용자가 모니터를 통해서 더빙되는 내용의 신호를 알아들을 수 있도록 해주면서, 또 고속더빙의 경우에 초래되는 하이측 가청주파수보상의 난제를 모우터를 중속으로 구동시킴으로써 보상해 줄 수 있도록 된 더블데크 카셋트의 모우터제어회로를 제공함에 그 목적이 있다.The present invention is designed to improve the above-mentioned disadvantages, and it is possible to control the speed of the motor at constant speed and high speed, and also to configure the motor to be driven at a constant speed and a medium speed of the constant speed, B on deck A When dubbing the contents of the tape to the deck at high speed, only high-speed copying is performed, while the signal output to the monitor can be muted, and when dubbing at medium speed, the user can recognize the signal of the dubbed content through the monitor. It is an object of the present invention to provide a motor control circuit of a double deck cassette that can compensate for the difficulty of compensating high side audio frequency caused by high speed dubbing by driving the motor at a medium speed.

이하 본 고안의 구성 및 작용, 효과를 에시도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration, operation, and effects of the present invention will be described in detail with reference to the drawings.

본 고안은 속도조절단자(PH, PL)와 모우터구동전압단자(+, -)를 갖춘 모우터 구동부(1) (1')에 저항(R1~R4)(R1'~R4')과 가변저항(VR1~VR3)(VR1'~VR3') 및 트랜지스터(TR1)(TR2)(TR1')(TR2')로 구성되어 상기 가변저항(VR1~VR3)(VR1'~VR3')의 가변에 의해 모우터의 속도를 제어해주는 속도제어부(2)(2')가 각각 연결되고, 이 속도제어부(2) (2')에 저항 (R7)(R8)(TR7')(TR8')과 트랜지스터(TR3)(TR4)(TR3')(TR4')로 구성되어 정속,중속,고속,으로 모우터를 구동시키는 경우에 상기 속도제어부(2)(2')를 스위칭제어해 주는 스위칭부 (3)(3')가 연결되며, 상기 스위칭부(3)(3')에 고속단자(a)와 중속단자 (b) 및 정속단자(c)가 갖추어진 속도제어스위치(S1)와 정항(R10) 및기록/재생스위치(S2)가 연결되고, 상기 속도제어 스위치(S1) 의 고속단자(a)에 상기 스위칭부(3)(3')의 트랜지스터 (TR3)(TR3') 의 베이스와 저항(R9)를 매개해서 모우터의 고속구동시 더빙신호를 뮤팅시키도록 기능하는 트랜지스터(TR5)의 베이스가 연결된 구조로 되어있다.The present invention is a variable (R1 ~ R4) (R1 '~ R4') and variable in the motor driver (1) (1 ') equipped with a speed control terminal (PH, PL) and motor driving voltage terminals (+,-) Resistors VR1 to VR3 (VR1 'to VR3') and transistors TR1 (TR2) (TR1 ') and TR2' to vary the resistance of the variable resistors VR1 to VR3 (VR1 'to VR3'). Speed controllers 2 and 2 ', which control the speed of the motor, are respectively connected, and resistors R7, R8, TR7', TR8 'and transistors are connected to the speed controller 2, 2'. A switching unit (3) consisting of (TR3) (TR4) (TR3 ') (TR4') for switching and controlling the speed control unit (2) (2 ') when driving the motor at constant speed, medium speed, and high speed; 3 'is connected, the speed control switch (S1) and the constant port (R10) equipped with a high speed terminal (a), a medium speed terminal (b) and a constant speed terminal (c) in the switching unit (3) (3') And the recording / reproducing switch S2, and the base and the resistor of the transistors TR3 and TR3 of the switching section 3 and 3 'are connected to the high speed terminal a of the speed control switch S1. (R9) Dog to have a structure connected to the base of a transistor (TR5) which functions so as to mute the dubbing signal during high-speed driving of the Motor.

제1도는 상기와 같이 구성된 본 고안의 회로도로서 더블데크카셋트에서 A데크로 부터 B데크로 테이프의 내용을 더빙시킬 때는 양 데크에서 녹음과 재생이 동시에 행하여 질 때만 가능하게 되고, 모우터의 속도제어는 더빙시에만 가능하도록 되어야 하므로 본 고안에 따른 회로에는 테이프더빙시에만 동작전압이(B+)이 인가되도록 해주고 있다. 그리고, 상기 모우터 구동부(1)(1') 에는 각각 속도조절단자(PH, PL)가 갖추어져 있으면서 모우터의 구동전압단자(+, -)가 갖추어져 있는데, 상기 속도조절단자 (PH, PL)에는 속도제어부(2)(2')의 가변저항 (VR1~ VR3)(VR1'~ VR3')의 저항치가변에 의해 일정한 구동전압(+, -)에 대한 전류량을 제어해줌으로서 모우터를 정속, 중속, 고속으로 제어해 줄 수 있게 된다.1 is a circuit diagram of the present invention configured as described above, when dubbing the contents of a tape from A deck to B deck in a double deck cassette, it is possible only when recording and playback are simultaneously performed on both decks. Since is to be possible only when dubbing, the circuit according to the present invention allows the operating voltage (B + ) to be applied only during tape dubbing. The motor driving units 1 and 1 'are provided with speed adjusting terminals PH and PL, respectively, and are provided with driving voltage terminals + and-of the motor, respectively. The motor is controlled at constant speed by controlling the amount of current to a constant driving voltage (+,-) by varying the resistance value of the variable resistors VR1 to VR3 (VR1 'to VR3') of the speed controller 2 (2 '). Can control at medium speed and high speed.

여기서 사용자가 A데크에서 B데크로 테이프내용을 정속으로 더빙하는 경우의 작용에 대해 설명하면, 먼저 기록/재생스위치(S2)를 기록의 위치(R)에 위치시키고, 속도제어스위치(S1)를 정속단자(C)에 접속시키면 동작전압 (B+)이 저항(R8)을 매개하여 트랜지스터(TR4)의 베이스단자에 입력되므로 트랜지스터(TR4)가 턴온되므로 트랜지스터(TR4)의 콜렉터단자의 전위가 로우레벨로 강하되므로 접속점(B)부분의 전위가 낮아지게 되어 트랜지스트(TR1)가 턴오프된다. 이에 따라 속도조절단자(PH, PL)사이의 전류는 저항(R1)을 통하여 가변저항(VR1)으로 흐르는 전류(11)와 저항(R6)을 통해 인가되는 동작전압(B+)에 의해 턴온되는 트랜지스터(TR2)를 통해 가변저항(VR3)방향으로 흐르는 전류(I3)의 합성전류로 결정되므로, 이경우 가변저항 (VR3)을 조정하여 전류(I3)를 조정해줌으로써, A, B데크에 대해 모우터(1)의 정속구동 RPM을 조정해 줄 수 있게 된다.Here, the operation of the user dubbing the contents of the tape from the deck A to the deck B at a constant speed will be described first. When connected to the constant speed terminal C, the operating voltage B + is input to the base terminal of the transistor TR4 via the resistor R8, so that the transistor TR4 is turned on, so the potential of the collector terminal of the transistor TR4 is low. Since the voltage drops to the level, the potential of the connection point B becomes low, and the transistor TR1 is turned off. Accordingly, the current between the speed control terminals PH and PL is turned on by the operating voltage B + applied through the current 11 flowing through the resistor R1 to the variable resistor VR1 and the resistor R6. Since it is determined as the synthesized current of the current I3 flowing in the direction of the variable resistor VR3 through the transistor TR2, in this case, the current I3 is adjusted by adjusting the variable resistor VR3, so that the A and B decks are gathered. It is possible to adjust the constant speed drive RPM of the rotor (1).

또한 사용자가 A데크에서 B데크로 테이프내용을 중속으로 더빙시키는 경우에는 속도제어스위치(S1)를 중속단자(b)에 접속시키면 동작전압(B+)이 트랜지스터(TR4')의 베이스단자에 입력되어 트랜지스터(TR4')가 턴온되므로 이 트랜지스터(TR4') 의 콜렉터단자의 전압에 의해서 접속점(A)부분의 전위가 저하되게 되고, 이에 따라 트랜지스터(TR2)가 턴오프되므로 속도조절단자(PH, PL)사이의 전류는 저항(R1)을 통하여 가변저항(VR1)으로 흐르는 전류(I1)와 저항(R5)을 통해 인가되는 동작전압(B')에 의해 턴온되는 트랜지스터 (TR1) 및 가변저항(VR2)으로 흐르는 전류(I2)와의 합성전류에 의해 A데크의 모우터속도가 결정되므로 상기 가변저항(VR2)을 조정해줌으로써 중속 RPM으로 모우터(1)의 속도를 조정해 줄 수 있게 된다.In addition, when the user dubs the tape contents from the deck A to the deck B at medium speed, the speed control switch S1 is connected to the medium speed terminal b so that the operating voltage B + is input to the base terminal of the transistor TR4 '. As the transistor TR4 'is turned on, the potential of the connection point A is lowered by the voltage of the collector terminal of the transistor TR4', and accordingly, the transistor TR2 is turned off so that the speed regulating terminal PH, The current between PL is turned on by the current I1 flowing through the resistor R1 to the variable resistor VR1 and the operating voltage B 'applied through the resistor R5 and the variable resistor (T1). Since the motor speed of the A deck is determined by the combined current with the current I2 flowing to the VR2), the speed of the motor 1 can be adjusted at a medium speed RPM by adjusting the variable resistor VR2.

또한 사용자가 A데크에서 B데크로 테이프내용을 고속으로 더빙을 하고 싶을 때에는 속도제어스위치(S1)를 고속단자(a)에 접속시키면동작전압(B+)이트랜지스터(TR3)와 트랜지스터(TR3')의 베이스단자에 각각 입력되므로 트랜지스터(TR3)와 트랜지스터(TR3')가 각각 턴온되고, 이에 따라 트랜지스터(TR3)와 트랜지스터(TR3')의 각 콜렉터단자전압에 의해서 접속점(A)과 접속점(B)부분의 전위가 저하되므로 트랜지스터(TR1)와 트랜지스터(TR2) 가 각각 턴오프되어 속도조절단자(PH, PL)사이의 전류는 저항(R1)과 가변저항(VR1)으로 흐르는 전류(I1)로되므로 가변저항(VR1)을 조정해 줌으로써 모우터의 속도를 고속 RPM으로 조정해 줄 수 있게 된다. 이 경우 가변저항(VR1 )의 가변으로 전류(I1)가 변화되어 중속, 정속의 RPM이 정확하게 조정되지 않는 경우가 있으므로 속도제어스위치(S1)를 "a" 단자부터 위치시켜 고속 RPM부터 조정을 하여 중속, 정속을 조정해주게 되면 최초전류(I1)가 고정되어 중속, 정속을 쉽게 조정해 줄 수 있다. 여기서, 상기 고속접점(a) 이 선택된 경우에는 뮤팅용 트랜지스터 (TR5)의 베이스에 동작전압(B+)이 인가되어 이 트랜지스터(TR5)가 턴온되는데, 이는 도시되지 않은 뮤팅회로에다 그 트랜지스터 (TR5)를 접속시키면 고속더빙시의 신호음을 뮤팅시킬 수 있게 된다.In addition, when the user wants to dub the contents of the tape from deck A to deck B at high speed, the speed control switch S1 is connected to the high speed terminal a, and the operating voltage (B + ) transistor (TR3) and transistor (TR3 ') are connected. Since the transistors TR3 and TR3 'are respectively turned on, the transistors A3 and B are connected by the collector terminal voltages of the transistors TR3 and TR3'. Since the potential of the portion decreases, the transistor TR1 and the transistor TR2 are turned off, respectively, and the current between the speed regulating terminals PH and PL becomes a current I1 flowing through the resistor R1 and the variable resistor VR1. Therefore, by adjusting the variable resistor (VR 1 ) it is possible to adjust the speed of the motor to a high RPM. In this case, since the current I1 is changed by the variable resistor VR1, the RPM of the medium speed and the constant speed may not be adjusted correctly. Therefore, the speed control switch S1 is positioned from the terminal “a” to adjust from the high speed RPM. By adjusting the medium speed and constant speed, the initial current (I1) is fixed so that the medium speed and constant speed can be easily adjusted. Here, when the high speed contact a is selected, the operating voltage B + is applied to the base of the muting transistor TR5 to turn on the transistor TR5, which is a muting circuit (not shown) and the transistor TR5. ), It is possible to mute the beeping sound at high speed dubbing.

한편 이상에서는 더블데크카셋트에서 A데크의 테이프내용을 B데크로 더빙시키는 경우에 대해서만 더빙시키고자 하는 경우만 설명했지만 , 모우터의 속도를 제어해서 정속, 중속, 했고속으로 더빙지만 B데크의 테이프내용을 A데크로 더빙시키는 경우의 모우터 속도 조절도 상기 동작과 유사하게 실시될 수 있게 된다.In the above description, only the case where the double deck cassette is to dub the contents of the deck of A deck from the deck to the B deck is explained. However, the speed of the motor is controlled to control the speed of the motor. Motor speed adjustment in the case of dubbing the contents to the A deck can be performed similarly to the above operation.

상기한 바와 같이 본 고안은 사용자가 테이프내용을 더빙시키자 하는 경우 모우터 속도를 제어해서 정속 ,중속,고속으로 더빙시킬수 있게 되고 또 고속 더빙시에 모우터의 속도가 너무 빠르게 되어 더빙내용에 관한 모니터음을 이행할 수 없었던 것을 중속으로 더빙시킬 수 있게 된다.As described above, the present invention allows the user to dub the contents of the tape so that the user can dub at constant speed, medium speed, and high speed by controlling the motor speed. You will be able to dub on medium speeds that could not be performed.
