본 고안은 테이프 레코더에 사용되는 자동선곡장치에 있어서, 테이프의 녹음시에 스위치의 원터치만으로 곡과 곡 사이에 일정한 길이의 무녹음 부분을 자동으로 형성시킴과 동시에 이를 표시하여 주는 자동선곡장치의 무녹음 제어회로에 관한 것이다.The present invention is an automatic selection device used in a tape recorder, which automatically forms and records a certain length of non-recording part between songs with only one touch of a switch when recording a tape. It relates to a recording control circuit.
테이프 레코더의 자동선곡장치에 있어서는 테이프에 녹음된 곡과 곡 사이의 무녹음 부분을 이용하여 원하는 곡을 자동으로 선택하게 되므로, 자동선곡장치를 사용하기 위해서는 녹음시에 테이프의 곡과 곡 사이에 일정한 길이(시간)의 무녹음 부분을 형성시켜야 한다.In the automatic selection device of the tape recorder, the desired song is automatically selected by using the non-recorded portion between the songs recorded on the tape. A recording part of length (time) should be formed.
그런데, 종래에는 자동편집기능(Edit 기능)의 스위치를 누르고 있는 동안에만 녹음뮤팅회로가 동작되므로 무녹음의 길이만큼 일정한 시간동안 스위치를 누르고 있어야 하는 불편함이 뒤따랐고, 또한 스위치를 누르는 시간으로 무녹음 부분을 형성시키므로 테이프의 곡과 곡 사이의 무녹음 부분이 일정치 못하게 되고 무녹음시에 이를 표시할 수 없는 결점이 있었다.However, in the related art, since the recording muting circuit is operated only while the switch of the automatic editing function (Edit function) is pressed, the inconvenience of having to press the switch for a predetermined time as long as the length of the recording is followed, and also the time for which the switch is pressed There was a flaw that the recording part between the song and the song on the tape became inconsistent and that it could not be displayed during recording.
본 고안은 이러한 점을 감안하여 스위치를 순간적으로 접속시키는 동작만으로 녹음뮤팅회로를 일정시간 동작시키어 일정길이의 무녹음 부분을 형성시킴과 동시에 무녹음중임을 표시하게 안출한 것으로 첨부한 도면에 의하여 본 고안의 구성 및 작용·효과를 상세히 설명하면 다음과 같다.In view of the above, the present invention operates a recording muting circuit for a certain time only by simply connecting a switch to form a recording part of a certain length, and at the same time, it shows that the recording is in progress. The construction, operation, and effects of the invention are described in detail as follows.
녹음뮤팅회로(1)(2)를 동작시키어 무녹음 부분을 형성시키는 회로에 있어서, 전원단자(B+)에 접속된 스위치(S1)는 저항(R1)을 통하여 콘덴서(C1), 트랜지스터(TR2)의 콜렉터 및 트랜지스터(TR1)의 베이스에 접속하고, 트랜지스터(TR1)의 에미터는 저항(R2)을 통하여 콘덴서(C2) 및 트랜지스터(TR2)의 베이스에 접속하며, 또한 트랜지스터(TR1)의 에미터는 저항(R4)을 통하여는 뮤팅회로(1)(2)에 콜렉터가 접속된 트랜지스터(TR3)(TR4)의 베이스에 접속하고, 저항(R5)을 통하여는 발광다이오드(LED1)에 콜렉터가 접속된 트랜지스터(TR5)의 베이스에 접속하여 구성시킨 것으로, 도면의 설명중 미설명부호 R6는 저항이다.In the recording muting circuit (1) circuit which forms a record part sikieo operation (2), a capacitor (C 1) via a switch (S 1) has a resistance (R 1) connected to a power supply terminal (B +), Connected to the collector of transistor TR 2 and the base of transistor TR 1 , and the emitter of transistor TR 1 to the base of capacitor C 2 and transistor TR 2 through resistor R 2 . In addition, the emitter of the transistor TR 1 is connected to the base of the transistor TR 3 (TR 4 ) in which the collector is connected to the muting circuit 1 (2) through the resistor R 4 , and the resistor R 5. ) is a light emitting diode (LED 1) the transistor (TR 5) that was configured to connect to the base, the description of the drawings, reference numeral R 6 of the collector is connected to the via is a resistance.
이와 같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.
전원(B+)이 인가되고, 별도의 녹음스위치를 단락하여 녹음상태로 되었을때 스위치(S1)를 접속시키게 되면, 전원(B+)은 스위치 (S1)와 저항(R1)을 통하여 콘덴서(C1)에 충전되고, 스위치(S1)가 순간적으로 접속되었다가 개방되어도 콘덴서(C1)의 충전전압은 트랜지스터(TR1)의 베이스(TR1)에 서서히 방전되므로 트랜지스터(TR1)는 도통상태로 된다. 따라서 트랜지스터(TR1)의 에미터에 일정전압이 출력되고, 이 일정전압은 저항(R4)을 통하여 트랜지스터(TR3)(TR4)의 베이스에 인가되어 트랜지스터(TR3)(TR4)를 도통시키므로 녹음뮤팅회로(1)(2)가 동작되어 무녹음 부분이 현성된다.When power (B + ) is applied and the separate recording switch is short-circuited and the switch (S 1 ) is connected, the power (B + ) is connected through the switch (S 1 ) and the resistor (R 1 ). a capacitor is charged to the (C 1), the switch (S 1) that even if the opening has been momentarily connected to the charging voltage of the capacitor (C 1) is so gradually discharged to the base (TR 1) of the transistor (TR 1) transistor (TR 1 ) Becomes a conductive state. Thus transistor a constant voltage to the emitter of the (TR 1) is output, a constant voltage is applied to the base of the transistor (TR 3) (TR 4) through a resistor (R 4) transistor (TR 3) (TR 4) Since the recording muting circuit (1) (2) is operated so that no recording portion is manifested.
또한, 이때 트렌지스터(TR1)의 에미터 출력전압은 저항(R5)을 통하여 트랜지스터(TR5)의 베이스에 인가되어 트랜지스터(TR5)를 도통시키므로 발광다이오드(LED1)가 점등되어 현재의 녹음상태가 무녹음상태임을 표시하게 된다.At this time, the emitter output voltage of the transistor TR 1 is applied to the base of the transistor TR 5 through the resistor R 5 to conduct the transistor TR 5 so that the light emitting diode LED 1 is turned on to present the current. It indicates that the recording status is no recording.
또한, 이때 트랜지스터(TR1)의 에미터 출력전압은 저항(R2)을 통하여 콘덴서(C2)에 충전되기 시작하고, 콘덴서(C2)에 일정전압이 충전되면 트랜지스터(TR2)의 베이스에 바이아스 전압이 인가되어 트랜지스터(TR2)를 도통시키므로 콘덴서(C1)의 충전전압은 트랜지스터(TR2)를 통하여 순간적으로 방전하게 된다.At this time, the emitter output voltage of the transistor TR 1 begins to be charged to the capacitor C 2 through the resistor R 2 , and when the capacitor C 2 is charged with a constant voltage, the base of the transistor TR 2 is charged. Since a bias voltage is applied to the transistor TR 2 to conduct the transistor, the charging voltage of the capacitor C 1 is discharged momentarily through the transistor TR 2 .
따라서, 트랜지스터(TR1)의 베이스에 바이아스 전원이 차단되어 트랜지스터(TR1)는 오프되고, 이에 따라 트랜지스터(TR1)의 에미터 출력전압이 저전위 상태로 되어 트랜지스터(TR1)(TR4)(TR5)를 오프시키므로 녹음뮤팅회로(1)(2)는 동작을 중지하여 무녹음 상태를 해제시키고, 발광다이오드(LED1)는 소등되어 무녹음 상태가 아님을 나타내게 된다. 따라서, 이때 무녹음 상태에서 해제되었음을 사용자가 인지하여 별도의 포즈위치를 단락시키게 되면 데크가 녹음동작을 중지하게 된다.Accordingly, it is a bias power down to the base of the transistor (TR 1) transistor (TR 1) is turned off, so that the emitter output voltage of the transistor (TR 1) is in a low potential state transistor (TR 1) (TR 4 ) Since the TR 5 is turned off, the recording muting circuit 1 and 2 stop the operation to release the no recording state, and the light emitting diode LED 1 is turned off to indicate that it is not the no recording state. Therefore, when the user recognizes that the recording is released in the no recording state and shorts a separate pose position, the deck stops the recording operation.
이와같이 트랜지스터(TR1)의 에미터 출력전압이 저항(R2)을 통하여 콘덴서(C2)에 충전되는 일정시간동안은 무녹음 상태를 유지하게 되므로 저항(R2)과 콘덴서(C2)의 시정수를 조정해 둠으로써 일정한 길이의 무녹음 부분을 형성시킬 수 있고, 이때의 무녹음 상태를 표시할 수가 있지 된다.In this way the transistor (TR 1) the emitter output voltage resistance (R 2) a capacitor (C 2) for a certain period of time, so to keep the non-recording state resistance (R 2) and capacitor (C 2) to be filled in through the By adjusting the time constant, no recording portion having a certain length can be formed, and the no recording state can be displayed at this time.
이상에서와 같이 본 고안은 스위치를 순간적으로 접속시키는 동작만으로 일정시간 동안 무녹음 부분이 형성됨과 동시에 무녹음 상태가 표시되므로 종래와 같이 스위치를 일정시간동안 눌러야 하는 불편함이 없게 되고, 테이프의 곡과 곡 사이에 무녹음 부분을 일정하게 형성시킬 수 있는 이점이 있게 된다.As described above, the present invention is formed without recording part for a certain time by the operation of connecting the switch instantaneously and at the same time the recording state is displayed, there is no inconvenience to press the switch for a certain time as in the prior art, the music of the tape There is an advantage that can form a constant recording portion between the and the song.
