이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

G. B. R 신호의 입력단을 OR회로(1)의 각단자에 접속하고, 상기 OR회로(1)의 출력단(OR1)에는 버퍼회로(2)를 연결함과 동시에, 동작스위치(SW)에 저항(R1)을 통하여 전원(Vcc1)에 접속하고, 저항(R3)을 거쳐 트랜지스터(Q1)의 베이스에 연결하며, 저항(R2)을 통하여 트랜지스터(Q1)의 콜렉터와 OR회로(1)에 접속한다.The input terminal of the GB R signal is connected to each terminal of the OR circuit 1 , the buffer circuit 2 is connected to the output terminal OR 1 of the OR circuit 1, and a resistor ( It is connected to the power supply Vcc 1 through R 1 ), and is connected to the base of the transistor Q 1 via a resistor R 3 , and the collector and OR circuit of the transistor Q 1 through a resistor R 2 ( Connect to 1).

또한 전원(Vcc2)단에 저항(R11)(R12)과 저항(R10)(R13)을 거쳐 트랜지스터(Q2)(Q3)의 각 에미터에 연결하고, 상기 트랜지스터(Q2)Q3)의 출력측인 콜렉터에는 음극선관(3)을 접속하며, 저항(R12)(R13)에는 버퍼회로(2)의 (B1)(B2)출력단이 다이오드(D1)(D2)를 통하여 G-OR회로(5)에 연결됨과 동시에 통상의 인버터 회로(4)에 접속되도록 한 것이다.In addition, the power supply Vcc 2 is connected to each emitter of transistors Q 2 and Q 3 through resistors R 11 and R 12 and resistors R 10 and R 13 , and the transistor Q 2 ) A cathode ray tube 3 is connected to the collector on the output side of Q 3 ), and the output terminal (B 1 ) (B 2 ) of the buffer circuit 2 is a diode (D 1 ) to a resistor (R 12 ) (R 13 ). It is connected to the G-OR circuit 5 via (D 2 ) and to the normal inverter circuit 4 at the same time.

상기와 같은 구성으로 이루어진 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention made of the above configuration as follows.

동작스위치(SW)를 온(ON)상태에 놓게 되면점은 하이레벨이 되므로 IC2의 출력은 오프(OFF)상태가 되어 인버터 회로(4)는 작동하지 OR회로(1)만 동작한다.When the operation switch (SW) is turned ON Since the point becomes high level, the output of the IC 2 is turned off, and the inverter circuit 4 does not operate but only the OR circuit 1 operates.

따라서 전원(Vcc1)이 저항(R1)(R3)을 통하여 트랜지스터(Q1)의 베이스에 인가되어 하이레벨이 되므로 턴온(TURN ON)되어 트랜지스터(Q1) 콜렉터는 로우레벨로 되어 오아회로(1)의 OR게이트(OR1)는 로우레벨이 된다.Therefore, since the power supply Vcc 1 is applied to the base of the transistor Q 1 through the resistors R 1 and R 3 to become a high level, the power supply Vcc 1 is turned on and the transistor Q 1 collector becomes low level. The OR gate OR 1 of the circuit 1 is at a low level.

이때 G와 B신호는 OR게이트(OR2)에 인가됨으로서 출력이 G＋B가 되어 OR 게이트 (OR3)에 입력되며, 또한 R신호는 OR게이트(OR4)를 거쳐 OR 게이트(OR3)에 동시에 입력된다.At this time, G and B signals at the same time to the OR gate (OR 2) is applied by being is input to the OR gate output is the G + B (OR 3), and R signal is an OR gate via an OR gate (OR 4) (OR 3) in Is entered.

따라서, OR 게이트(OR3)의 출력은 G＋B＋R이 되어 OR 게이트(OR1)는 로우레벨＋G＋B＋R로 출력되어 버퍼회로(2)에 입력되며 버퍼회로(B1)에서 출력된 R＋G＋B＋합성신호는 다이오드(D1)과 저항(R12)을 거쳐 G－OR회로(5) 트랜지스터(Q2)의 에미터에 인가도고 다른 버퍼회로(B2)의 출력은 다이오드(D2)와 저항(R13)을 경유하여 G－OR회로(5)의 트랜지스터(Q3)에 입력되어 트랜지스터(Q2)(Q3)의 출력단인 콜렉터에서 합성 된후 음극선과 구동회로에 5V의 TTL 레벨로 (R＋G＋B＋합성신호) 입력되어 약 40Vpp의 부극성 신호로 증폭하여 음극선관(3)의 G건(GUN)을 동작하게 하므로서 디스플레이를 녹색색상으로 재현하도록 한 것으로서 G－OR회로(5)에 다이오드(D1)(D2)를 통한 G＋B＋R 신호만이 인가되어 음극선관(3)의 G－GUN 만을 동작하게 된다.Therefore, the output of the OR gate OR 3 becomes G + B + R, and the OR gate OR 1 is output at the low level + G + B + R, and is input to the buffer circuit 2, and the R + G + B + synthesis signal output from the buffer circuit B 1 is a diode ( D 1 ) and resistor (R 12 ) are applied to the emitter of G-OR circuit (5) transistor (Q 2 ) and the output of other buffer circuit (B 2 ) is diode (D 2 ) and resistor (R 13 ). Is inputted to the transistor Q 3 of the G-OR circuit 5 through the synthesizer and synthesized by the collector, which is the output terminal of the transistors Q 2 and Q 3 , and then to the cathode and driving circuits at a TTL level of 5 V (R + G + B + synthesis signal). as one so as to reproduce the hameuroseo to input the operation to (gUN) G s of the tube (3) for amplifying a negative polarity signal of about 40Vpp displayed in green color diode in G-OR circuit (5) (D 1) (D Only G + B + R signal through 2 ) is applied to operate only G-GUN of the cathode ray tube 3.

한편 스위치(SW)가 오프(OFF)되면점은 로우레벨(LOW LWVEL)이 되어 IC2는 정상동작하게 R. G. B 단 모두 동작 하게 되는 것이다.On the other hand, when the switch (SW) is off (OFF) The point becomes the low level (LOW LWVEL) so that IC 2 operates normally.

이상에서 상술한 바와 같이 동작하는 본 고안은 화면상에 글자 및 그래픽 등이 녹색으로 나타나게 되어 사용자의 눈의 피로를 덜어 줌으로 업무의 효율을 높일수 있고 기기의 신뢰도를 높일수 있는 유용한 고안인 것이다.The present invention operating as described above is a useful design that can increase the efficiency of the work and increase the reliability of the device by reducing the fatigue of the user's eyes because the letters and graphics appear green on the screen.
