본 고안은 레이저 프린터 등과 같이 고압을 사용하는 기기에 있어서, 고압이 발생되면, 그 고압이 발생됨을 표시하게 한 고압발생 표시회로에 관한 것이다.The present invention relates to a high-pressure generation display circuit for indicating that the high pressure is generated when a high pressure is generated in a device using a high pressure, such as a laser printer.

종래에는 고압이 발생되어도 고압이 발생되는 것을 표시하게 구성하지 않았으므로 사용자는 고압이 정상으로 발생하여 공급되는지를 판별할 수 있는 결함이 있었다.Conventionally, since the high pressure is not configured to display that the high pressure is generated, the user has a defect that can determine whether the high pressure is normally generated and supplied.

본 고안은 이와같은 종래의 결함을 감안하여, 고압이 발생되면, 발광 다이오드를 점등시켜 고압이 발생됨을 표시하게 안출한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention in view of the conventional defects, such that when a high pressure is generated, the light emitting diode is turned on to indicate that a high voltage is generated, which will be described in detail with reference to the accompanying drawings.

첨부된 도면은 본 고안의 표시회로도로서, 이에 도시한 바와같이 교류전원(AC)이 스위치(SW1)를 통해 일차측(T11)에 접속된 트랜스(T1)이 이차측(T12)를 정류기(1)의 입력단자에 접속하고, 정류기(1)의 출력단자에는 저항(R1)과, 병렬 접속된 가변저항(VR1) 및 바리스터(VA)와 저항(R2)을 직렬로 접속하여 고압출력부(2)를 구성하고, 상기 저항(R2)의 양단자는 레귤레이터(3)를 통해 콘덴서(C3)와 직렬 접속된 발광다이오드(LED1) 및 저항(R3)에 접속하여 구성한 것이다.The appended drawing is a display diagram of the subject innovation, and thus as shown alternating current power (AC) is switched transformer (T 1) connected to the primary side (T 11) through (SW 1) the secondary side (T 12) Is connected to the input terminal of the rectifier 1, and the output terminal of the rectifier 1 is connected in series with a resistor (R 1 ), a variable resistor (VR 1 ), a varistor (V A ), and a resistor (R 2 ) connected in parallel. The high voltage output unit 2 is connected to each other, and both terminals of the resistor R 2 are connected to the light emitting diode LED 1 and the resistor R 3 connected in series with the capacitor C 3 through the regulator 3 . It is connected and configured.

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

교류전원(AC)이 인가되고, 스위치(SW1)가 단락되면, 교류전원(AC)는 스위치(SW1)를 통해 트랜스(T1)의 일차측(T1)에 인가되어 트랜스(T1)의 이차측(T12)에는 승압된 교류전원이 유도되고, 그 유도된 교류전원은 정류기(1)를 통해 고압정류된 후 저항(R1, R2)을 통해 가변저항(VR1) 및 바리스터(VA)의 양단자에 인가되면서 고압을 출력하며, 저항(R2)의 양단자의 전압은 레귤레이터(3)를 통해 정전압으로 된 후 발광다이오드(LED1)에 인가되므로 발광다이오드(LED1)는 점등되어 고압이 출력됨을 표시하게 된다.AC power source (AC) is applied, a switch (SW 1) is when the short-circuit, the AC power supply (AC) is applied to the primary side (T 1) of the transformer (T 1) via a switch (SW 1) transformer (T 1 Stepped to the secondary side (T 12 ) of the AC power is induced, the induced AC power is rectified by a high-pressure rectifier through the rectifier (1) and then through the resistors (R 1 , R 2 ) variable resistor (VR 1 ) and as applied to the positive terminal of the varistor (V a), and outputs a high voltage, voltage's two ends of the resistor (R 2) it is so applied on after a constant voltage through a regulator 3 light-emitting diode (LED 1) light emitting diode (LED 1 ) Lights up to indicate that high voltage is output.

이와같은 상태에서 교류전원(AC)이 인가되지 않거나 또는 여러가지의 이유로 인하여 고압이 출력되지 않게 되면, 저항(R2)의 양단간의 전압이 없이 레귤레이터(3)가 저전압을 출력하므로 발광다이오드(LED1)가 점등되지 않아 고압이 출력되지 않음을 표시하게 한다.In this state, when the AC power is not applied or the high voltage is not output due to various reasons, the regulator 3 outputs a low voltage without voltage between both ends of the resistor R 2 , so that the LED 1 ) Is not lit, indicating that no high voltage is output.

이상에서 상세히 설명한 바와같이 본 고안은 고압이 출력되면, 발광다이오드가 점등되므로 사용자는 고압의 출력유무를 바로 판별할 수 있는 효과가 있다.As described in detail above, the present invention has the effect that the user can directly determine whether the output of the high voltage since the light emitting diode is turned on when the high pressure is output.
