본 고안은 카셋트 데크가 3개인 트리데크 카셋트 테이프 레코더의 제어회로에 관한 것으로, 특히 3개의 데크가 순차적으로 연속재생기능을 실행하도록 된 전자회로에 관한 것이다.The present invention relates to a control circuit of a tri-deck cassette tape recorder having three cassette decks, and more particularly, to an electronic circuit in which three decks sequentially execute a continuous playback function.
종래에는 2개의 카셋트 데크를 시스템으로 구성해서 더빙기능 및 연속재생 기능을 실행시킬 수 있도록 된 더블데크 카셋트 테이프 레코더가 있었으나, 이러한 시스템에서는 단지 두개의 데크로만 구성되어있기 때문에 하나의 데크를 이용하여 오디오신호의 재생기능을 실행시키면서 또 다른 오디오신호를 더빙 녹음시키거나, 정속 또는 고속으로 2개의 데크에 더빙녹음 시키거나, 합성녹음 등을 실행시킬 수 없는 불편함이 있었다. 따라서 상기와 같은 불편함을 제거하고자 트리데크 카셋트 테이프 레코더의 필요성이 대두되었으며, 이러한 트리데크 카셋트 테이프 레코더의 여러기능 가운데 특히 본 고안에서는 링카운터를 수동 또는 자동으로 동작시켜서 3개의 데크에서 순차적으로 연속적인 재생기능을 실행할 수 있도록 된 트리데크 카셋트 테이프 레코더의 제어회로를 제공함에 그 목적이 있는 것이다.Previously, there was a double-deck cassette tape recorder in which two cassette decks were configured as a system to perform a dubbing function and a continuous playback function. However, since these systems consist of only two decks, audio is generated using one deck. While the signal reproduction function was executed, it was inconvenient to dub another audio signal, to dub two decks at a constant or high speed, or to perform synthetic recording. Therefore, the necessity of a tri-deck cassette tape recorder has emerged in order to eliminate such inconveniences, and among the various functions of such a tri-deck cassette tape recorder, in particular, the present invention operates the ring counter manually or automatically to sequentially operate the three decks. It is an object of the present invention to provide a control circuit of a Trideck cassette tape recorder capable of performing an ordinary playback function.
이하 본고안의 구성 및 작용, 효과를 예시도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the configuration, operation, and effects of the present disclosure will be described in detail with reference to the accompanying drawings.
본 고안은 B+전원단자에는 각 데크의 리프스위치(S1)(S2)(S3) 및 다이오드(D1∼D8), 저항(R4∼R10), 트랜지스터(TR6), 콘덴서(C1∼C4)로, 이루어진 데크선택회로(1)와 자동/수동절환회로(2)에 있는 전환스위치(SA)를 차례로 매개하여 링카운터(3)의 입력단(IN)이 연결되고, 자동/수동절환회로(2)와 링카운터(3)의 리셋트단자(Re)사이에는 자연회로(4)와 리셋트스위치(SC)가 연결되며, 링 카운터(3)의 출력단(T1∼T3)과 리프스위치(S1∼S3)의 온단자사이에는 저항(R16∼R18)과 앤드게이트(G1∼G3)의 및 트랜지스터(TR1∼TR3)(T1∼T3)로 이루어진 모터구동회로(5)를 매개하여 각 데크의 모터(M1∼M3)가 연결됨과 더불어 링카운터(3)의 출력단(T1∼T3)에는 발광다이오드(L1∼L3)와 저항(R1∼R3)으로 이루어진 표시회로(6)가 연결된 구조로 되어 있다.According to the present invention, the B + power terminal has leaf switches (S 1 ) (S 2 ) (S 3 ), diodes (D 1- D 8 ), resistors (R 4 -R 10 ), transistors (TR 6 ), The input terminal IN of the ring counter 3 is connected to the condenser C 1 to C 4 via the deck selection circuit 1 consisting of the deck selection circuit 1 and the switching switch S A in the automatic / manual switching circuit 2 in order. The natural circuit 4 and the reset switch S C are connected between the automatic / manual switching circuit 2 and the reset terminal Re of the ring counter 3, and the output terminal of the ring counter 3 T 1 ~T 3) and a leaf switch (S 1 ~S 3), the resistance (R1 6 between the on-terminal ~R 18) and aND gate (G 1 ~G 3) and a transistor (TR 1 ~TR 3) ( in the light emitting diode 1 T ~T 3) to mediate the motor driving circuit 5, an output terminal (T 1 ~T 3) of each deck motor (M 1 ~M 3) the ring counter 3 with the connected consisting of ( L 1 ~L 3) and the resistor (R 1 ~R 3) consisting of a display circuit 6 can be attached to the structure .
미설명부호 S8는 수동선택스위치 a는 각 리프스위치를 온시켰을 때의 접속단자, b는 각 리프스위치를 오프시켰을 때의 접속단자를 나타낸다.Reference numeral S 8 denotes a manual selection switch a for a connection terminal when each leaf switch is turned on, and a b for a connection terminal when each leaf switch is turned off.
제1도는 본 고안의 회로도를 나타낸 것으로, 각 리프스위치(S1∼S3)는 데크를 구동시키기 위하여 PW 단으로 B+전원을 공급하였을 때 온상태에서 각 해당 다이오드(D1∼D2)를 통해 해당 데크에 B+전원을 공급함과 더불어 해당데크의 모터를 구동시키기 위하여 모터구동회로(5)로 B+전원을 공급하도록 연결된 것이다.1 is a circuit diagram of the present invention, each leaf switch (S 1 ~ S 3 ) is a diode (D 1 ~ D 2 ) in the on state when the B + power supply to the PW stage to drive the deck In addition to supplying the B + power to the deck through the motor to drive the motor of the deck is connected to supply the B + power to the motor drive circuit (5).
콘덴서(C1∼C3)(C5∼C7)는 채터링방지용 콘덴서이다.The capacitors C 1 to C 3 (C 5 to C 7 ) are capacitors for preventing chattering.
먼저 3개의 데크를 수동으로 동작시키는 경우에 대해 설명하면, 처음에 3개 데크를 온 시키고, 절환스위치(SA)르 수동위치에 놓는다. 그러면 각 리프스위치(S1∼S3)가 온되어 B+전원이 다이오드(D1∼D3)를 통하여 각 셋트에 공급되어지는 한편 저항(R15)을 통하여 트랜지스터(TR4)의 베이스에 공급되는데, 콘덴서(C8)에 충전되는 시간동안 트랜지스터(TR4)의 오프상태가 유지되므로, 트랜지스터(TR5)가 변온되어 링카운터(3)의 리셋트단자(Re)가 로우레벨이 되어 링카운터(3)가 리셋트된다. 그러다가 콘덴서(c8)가 충전을 끝내게 되면 트랜지스터(TR4)가 턴온됨에 따라 트렌지스터(TR5)가 턴오프되므로 링카운터(3)는 동작준비상태에 접어들게된다. 이때 수동선택스위치(S4)를 한번누르게 되면 B+전원이 저항(R15)(R12)및 수동선택스위치(S8), 자동/수동절환스위치(SA), 저항(R11)을 차례로 통하여 순간적인 펄스로 공급되므로 링카운터(3)의 출력단자(T1)가 하이레벨된다. 따라서 앤드게이트(G1)의 양 입력단자가 모두 하이레벨이 되므로 출력단으로 하이레벨이 출력되는 트랜지스터(TR1)가 턴온되므로서 제1데크의 모터(M1)가 구동되므로써 제1데크에서 재생동작이 실행되어진다.First, the case of manually operating the three decks, the first three decks are turned on, the switch (S A ) is put in the manual position. Then, each leaf switch S 1 to S 3 is turned on so that B + power is supplied to each set through the diodes D 1 to D 3 , while at the base of the transistor TR 4 through the resistor R 15 . Since the transistor TR 4 is kept off during the charging time of the capacitor C 8 , the transistor TR 5 is turned on so that the reset terminal R e of the ring counter 3 is set to a low level. The ring counter 3 is reset. Then, when the capacitor c 8 finishes charging, the transistor TR 5 is turned off as the transistor TR 4 is turned on, and thus the ring counter 3 enters an operation ready state. At this time, if the manual selection switch (S 4 ) is pressed once, the B + power supply turns on the resistor (R 15 ) (R 12 ), the manual selection switch (S 8 ), the automatic / manual switching switch (S A ), and the resistor (R 11 ). The output terminal T 1 of the ring counter 3 is high level because it is supplied in an instantaneous pulse through one another . Therefore, since both input terminals of the AND gate G 1 become high level, the transistor TR 1 outputting the high level to the output terminal is turned on, so that the motor M 1 of the first deck is driven to reproduce on the first deck. The action is executed.
다음에 제2데크를 구동시키기 위하여 수동선택 스위치(SB)를 누르게 되면 전술한 바와 같이 B+전원이 링카운터(3)의 입력단(IN)으로 공급되어 링카운터(3)는 다음출력단인 출력단(T2)으로 하이레벨을 출력하게 된다. 따라서 앤게이트(G2)의 출력단에서 하이레벨이 되어 트랜지스터(TR1)가 턴온되므로써 제2데크의 모터(M2)가 구동됨에 따라 제2데크에서 재생동작이 실행되어진다.Next, when the manual selection switch S B is pressed to drive the second deck, as described above, B + power is supplied to the input terminal IN of the ring counter 3 so that the ring counter 3 is the next output terminal. The high level is output to (T 2 ). Accordingly, as the transistor TR 1 is turned on at the output terminal of the angate G 2 and the transistor TR 1 is turned on, the regeneration operation is performed on the second deck as the motor M 2 of the second deck is driven.
수동선택스위치(SB)를 또 다시 누르게 되면 전술한 바와 같은 전원공급에 의하여 링 카운터(3)의 출력단(T3)에서만 하이레벨이 출력되므로 모터(M3)가 구동됨에 따라 제3데크에서 재생기능이 실행되어진다.When the manual selection switch S B is pressed again, the high level is output only at the output terminal T 3 of the ring counter 3 by the power supply as described above, and thus, the motor M 3 is driven. The playback function is executed.
링카운터(3)의 출력단(T1∼T3)에서 하이레벨이 출력될대 표시회로(5)에 있는 해당 발광다이오드가 점등되므로 사용자는 어떤 데크에서 재생기능이 실행되고 있음을 알 수 있게 된다.A ring counter 3 an output terminal (T 1 ~T 3) at a high level, so that the light-emitting diode lights up in the display for the circuit 5 to be output from the user can know that the reproducing function is running on any deck .
3개의 데크를 자동으로 동작시키는 경우에는 각 데크를 온시키고 절환스위치(SA)를 자동위치로 접속시키면, 최초에 리프스위치(S1)가 온될때 B+전원은 저항(R8)과 콘덴서(C4)의 시정수에 의한 지연시간(T=0.63R8C4)만큼 지연된 다음에 링카운터(3)의 입력단(IN)에 펄스를 공급하게 되어, 링카운터(3)의 출력단(T1)에서 하이레벨이 출력되므로 표시회로(6)의 발광다이오드(L1)가 점등되어 제1제크가 구동되고 있음을 알림과 동시에 앤드게이트(G1)에서도 하이레벨이 출력되어 트랜지스터(TR1)가 턴온됨에 따라 제1데크의 구동모터(M1)가 구동된다. 그러다가 제1데크의 재생동작이 끝나 리프스위치(S1)가 오프되면 순간적으로 링카운터(3)에 공급되던 펄스가 없어지지만 B+전원이 리프스위치(S1)의 오프단자(b)와 저항(R6) 및 다이오드(D6)를 차례로 통하여 트랜지스터(TR6)를 턴온시킨 다음에 다이오드(D7)와 절환스위치(SA)를 통하여 링카운터(3)의 입력단(IN)에 입력되므로, 링카운터(3)는 출력단(T2)으로 하이레벨을 송출하게 되어 제2데크의 모터(M2)가 구동되는 한편 해당 발광다이오드(L2) 가 점등되어 제2데크에서 재생기능이 실행되고 있음을 표시하게 된다.When operating three decks automatically, turn on each deck and connect the selector switch (S A ) to the automatic position. When the leaf switch (S 1 ) is first turned on, the B + power supply is the resistor (R 8 ) and the condenser. After the delay by the time constant of (C 4 ) (T = 0.63R 8 C 4 ), the pulse is supplied to the input terminal IN of the ring counter 3, and the output terminal T of the ring counter 3 is 1) light emitted since the high level, the output display circuit 6, the diode (L 1) lights up to the first Zeke is driven and that the alert at the same time the high level, the output at the aND gate (G 1), the transistor (TR 1 As) is turned on, the driving motor M 1 of the first deck is driven. When the leaf switch S 1 is turned off after the regeneration operation of the first deck, the pulse supplied to the ring counter 3 disappears instantaneously, but B + power is applied to the off terminal b of the leaf switch S 1 and the resistor. Since the transistor TR 6 is turned on through R 6 and diode D 6 in turn, it is input to the input terminal IN of the ring counter 3 through the diode D 7 and the changeover switch S A. , The ring counter 3 transmits a high level to the output terminal T 2 so that the motor M 2 of the second deck is driven while the corresponding light emitting diode L 2 is turned on to perform the regeneration function on the second deck. Will be displayed.
자동연속 재생동작을 실행시키기 위해서는 링카운터(3)의 리셋트가 입력펄스보다 빨리 이루어져야 하므로 트랜지스터(TR4)가 온되어 시간(T=0.63R13C8)이 입력펄스의 지연시간(T=0.63R8C4)보다빠르게 설정되어있다.In order to execute the automatic continuous regeneration operation, the reset of the ring counter 3 must be performed earlier than the input pulse, so that the transistor TR 4 is turned on and the time (T = 0.63R 13 C 8 ) is the delay time of the input pulse (T = It is set faster than 0.63R 8 C 4 ).
상기와 같이 본 고안은 3개의 카셋트데크로 구성된 트리데크 카셋트 테이프 레코더에서 자동으로 연속재생기능을 실행시킬 수 잇고, 3개의 데크중 필요한 데크만을 임으로 선택동작시킬 수도 있는 장점이 있다.As described above, the present invention can automatically execute a continuous playback function in a tri-deck cassette tape recorder composed of three cassette decks, and has the advantage of selectively selecting and operating only the decks required among the three decks.
