본 고안은 바테리 전원을 사용하는 소형 라디오-카세트녹음기등에 있어, 녹음 상태 지시와 바테리 수명 검출지시를 겸하여 표시할수 있는 회로에 관한 것이다.The present invention relates to a circuit capable of displaying both a recording status indication and a battery life detection instruction in a small radio-cassette recorder using a battery power source.
종래에도 이와같은 지시를 겸한 회로가 있었으나, 그 구성이 복잡하여 실용화하기에는 적합하지 못하였다.Conventionally, there existed a circuit which served as such an instruction, but its configuration was complicated and it was not suitable for practical use.
본 고안은 이러한 점을 감안하여 간단한 회로 구성으로서도 녹음 상태지시 및 바테리 수명 검출 지시를 겸하여 표시할 수 있도록 고안한 것으로서, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is designed to display both the recording status instruction and the battery life detection instruction even with a simple circuit configuration in view of these points, which will be described in detail with reference to the accompanying drawings.
녹음, 재생 선택스위치(SW1)의 재생측단자(P)에 저항(R1),(R2)을 통하여 트랜지스터(TR1)의 베이스를 접속하고, 그의 콜렉터에 발광다이오드(LED) 및 콘덴서(C1)를 병렬로 접속한다.The base of the transistor TR 1 is connected to the reproducing side terminal P of the recording and reproducing selection switch SW 1 through the resistors R 1 and R 2 , and a light emitting diode LED and a capacitor are connected to the collector thereof. Connect (C 1 ) in parallel.
미설명부호(E)는 바테리 전원이고, SW2는 전원스위치, R3는 저항, R는 녹음측단자, C는 공통단자이다.Reference numeral E denotes a battery power source, SW 2 is a power switch, R 3 is a resistor, R is a recording terminal, and C is a common terminal.
이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
제 1 도에 있어 재생스위치(SW1)를 단자(C),(P)가 상호 접속되는 재생측으로 세팅한 상태에서 제 2(a) 도에 도시한 임의의 시간(t1)에서 전원스위치(SW2)를 온 상태로 하면, 바테리 전원(E)은 저항(R1)(R2)에 의하여 분배되어 트랜지스터(TR1)의 베이스에 인가되므로 트랜지스터(TR1)가 도통되어 그의 콜렉터 전위는 거의 0전위가 되므로 발광다이오드(LED)의 애노우드측 전위는 로우 상태가 되어 발광다이오드(LED)는 발광하지 않으므로 바테리 전원(E)의 수명은 정상임을 알려준다.In Fig. 1 , the power switch ( 1 ) is set at any time t 1 shown in Fig. 2 (a) with the regeneration switch SW 1 set to the regeneration side where the terminals C and P are interconnected. When the SW 2) in the on state, the batteries power (E) is a resistance (R 1) (R 2) applied to the distribution is the base of the transistor (TR 1), by since the transistor (TR 1) interconnecting its collector potential is Since the potential of the anode side of the light emitting diode (LED) becomes low because the light emitting diode (LED) becomes almost zero, the life of the battery power source (E) is normal because the light emitting diode (LED) does not emit light.
이때 트랜지스터(TR1)의 캐리어 확산으로 턴온(Turn on) 되지 아니하는 짧은 시간동안에, 바테리 전원(E)이 저항(R3)을 통하여 순간적으로 발광다이오드(LED)를 도통시키어 회로가 오동작되는 것을 방지하기 위하여 발광다이오드(LED)의 양단간에 콘덴서(C1)를 병렬 접속하여 순간전류를 흡수하도록 한다.At this time, the battery power supply (E) instantaneously conducts the light emitting diode (LED) through the resistor (R 3 ) for a short time that is not turned on due to carrier diffusion of the transistor (TR 1 ), the circuit malfunctions. In order to prevent this, the capacitor C 1 is connected in parallel between both ends of the light emitting diode LED to absorb the instantaneous current.
상기한 회로 상태를 지속하다가 장기간 사용에 의하여 바테리 전원(E)이 점차 감소됨에 따라 저항(R1,R2)으로 분배되어 트랜지스터(TR1)의 베이스에 가해지는 바이어스 전압도 감소하게 된다.Had maintained a state in which the circuit is distributed to the resistor (R 1, R 2) in accordance with a gradually reduced power batteries (E) by a long-term use is reduced bias voltage is applied to the base of the transistor (TR 1).
이와같이 감소되는 전압이 제 2(a) 도에 도시한 바와같이 전압(V1)이 치 이하(시간(t2)이하)로 하강하게 되면, 트랜지스터(TR1)의 베이스 바이어스는 임계(Threshole)전압까지 하강하게 된다.In this way when the voltage is reduced to fall in claim 2 (a) a voltage (V 1) a value below (time (t 2) or less) as shown in Figure, a base bias of the transistor (TR 1) is a threshold (Threshole) To the voltage.
따라서, 트랜지스터(TR1)는 시간(t2)에서 부터 서서히 턴 오프 영역으로 돌입하게 되어 저항(R3)을 통하여 흐르는 전류는 트랜지스터(TR1)의 콜렉터-에미터간으로 흐르기도 하고, 발광다이오드(LED1)의 애노우드측으로 흐르게 된다.Accordingly, the transistor TR 1 gradually enters the turn-off region from the time t 2 so that the current flowing through the resistor R 3 flows between the collector-emitter of the transistor TR 1 , and the light emitting diode It flows to the anode side of (LED 1 ).
이와같은 상태에서 바테리 전원(E)이 더욱더 감소되어 트랜지스터(TR1)가 완전히 오프되는 시점에서는 제 2(b) 도에 도시한 바와같이 발광다이오드(LED)의 양단전압이 최대로 증가될때 발광다이오드(LED)를 가장 밝게 점등시키게 되며. 이후 점차로 바테리 전원(E)이 감소됨에 따라 발광다이오드(LED)의 밝기가 약해지고, 시간(t3)에 도달하면 발광다이오드(LED)가 완전히 소등하게 된다.In this state, when the battery power source E is further reduced and the transistor TR 1 is completely turned off, the light emitting diode when the voltage across the light emitting diode LED is maximally increased as shown in FIG. 2 (b). (LED) lights up the brightest. Afterwards, as the battery power E gradually decreases, the brightness of the light emitting diodes LED is weakened, and when the time t 3 is reached, the light emitting diodes LED is completely turned off.
즉, 시간(t2)에서 시간(t3)동안 까지는 바테리 수명이 소모되어 교환할 시기가 된 것을 발광다이오드(LED)의 점등 상태로서 알려주게 되는 것이다.That is, from the time t 2 to the time t 3 , the battery life is consumed and the time to replace the battery is informed as the lighting state of the LED.
한편 전원스위치(SW2)를 온하고, 녹음, 재생 선택 스위치(SW1)를 녹음측으로 세팅하면 스위치(SW1)의 단자(C),(P)가 상호 접속되고, 단자(C),(P)는 상호 계방되어 트랜지스터(TR1)의 베이스에 가해지는 바테리 전원(E)은 차단되어 트랜지스터(TR1)는 부도통 상태가 되므로 이 경우에 바테리 전원(E)은 저항(R3)을 통하여 발광다이오드(LED)의 애노우드측에 공급되어 발광다이오드(LED)를 점등시키게 되므로, 기기가 녹음 상태중임을 표시하게 되는 것이다.On the other hand, if the power switch SW 2 is turned on and the recording and playback selection switch SW 1 is set to the recording side, the terminals C and P of the switch SW 1 are interconnected, and the terminals C and P) is the Battery power (E) is cut off the transistor (TR 1) is a power source (E) batteries in this case, since the default barrel state resistance (R 3) is applied to the base of the cross is gyebang transistor (TR 1) Since the light emitting diode LED is supplied to the anode side of the light emitting diode LED, the device is in a recording state.
이와같이 동작되는 본 고안은 바테리 전원을 사용하는 소형라디오-카세트 녹음기 등에 있어, 간단한 회로 구성으로서 녹음 상태지시기 및 바테리 수명 검출 지시기를 겸할 수가 있는 것이어서, 재조 원가 절감 및 공정 단순화를 꾀할 수 있는 실용적인 고안인 것이다.In this way, the present invention operates in a small radio-cassette recorder using a battery power source, and has a simple circuit configuration that can serve as a recording status indicator and a battery life detection indicator, thereby reducing the manufacturing cost and simplifying the process. will be.
