제1도는 본 고안 장치의 회로도.1 is a circuit diagram of the device of the present invention.

본 고안은 모니터장치에 입력되는 두가지의 다른 수직 동기 입력 신호를 모니터 장치의 화면에서 수직크기가 동일하게 표시되도록 할 수 있는 이중화면 크기 조절장치에 관한 것이다.The present invention relates to a dual screen size adjusting device capable of displaying two different vertical synchronizing input signals inputted to the monitor device to have the same vertical size on the screen of the monitor device.

종래에는 모니터장치의 로직보드 또는 컴퓨터에서의 수직동기 신호나 외부 입력 신호의 수직동기 신호 두가지가 입력되어도 모니터 장치에 설치된 한가지 수직 사이즈 회로로서 처리하므로써 두가지 수직동기 신호가 입력되면 이에 따라서 모니터 화면의 크기가 변동될 뿐만 아니라 화면의 일부분이 모니터 화면에 나타나지 않게 되는 단점이 있다.Conventionally, even if two vertical synchronization signals from a logic board of a monitor device or a computer or two vertical synchronization signals of an external input signal are input, the two screens are processed as one vertical size circuit installed in the monitor device. Not only does this change, but part of the screen does not appear on the monitor screen.

본 고안은 이러한 종래의 단점을 해결하기 위하여 두 개의 다른 수직 신호 입력을 두 개의 전압분배장치를 각각 거치도록 하므로써 동일한 수직크기를 얻도록 하여 다른 수직 신호 입력이 모니터 장치에 각각 입력되어도 모니터 화면의 크기가 변동되지 않으며 화면이 항상 전체적으로 나타날 수 있는 이중수직 동기 입력을 갖는 모니터 장치용 이중 화면 크기 조절장치를 제공하는 것을 목적으로 하며 이하 첨부된 도면을 참조 하면서 본 고안의 구성, 작용효과를 설명하면 다음과 같다.In order to solve the above disadvantages, the present invention obtains the same vertical size by passing two different vertical signal inputs through two voltage dividers, respectively, so that the size of the monitor screen can be obtained even if different vertical signal inputs are respectively input to the monitor device. The purpose of the present invention is to provide a dual screen size adjusting device for a monitor device having a dual vertical synchronous input that does not change and the screen always appears as a whole. The configuration and effect of the present invention will be described below with reference to the accompanying drawings. Same as

제1도를 참조하면 본 고안장치의 구성은 수직신호입력단자(1)는 결합콘덴서(C1)을 통하여 편향요크코일(L1)의 일측에 연결하고 편향요크코일(L1)의 타측은 가변저항(VR1, VR2)과 저항(R1)을 통하여 접지하며, 가변저항(VR1, VR2)의 가동자는 저항(R2,R3)을 통하여 트랜지스터(Q1, Q2) 의 콜렉터에 각각 연결하고, 트랜지스터(Q1,Q2)의 에미터는 수직구동 및 수직발진기(2)에 공통접속하되, 트랜지스터(Q1)의 베이스는 저항(R7,R8)을 통하여 전원(Vcc)에 연결하며, 트랜지스터(Q2)의 베이스는 저항(R4)를 통하여 모드신호입력단자(3)에 연결하고 , 모드신호입력단자(3)는 바이어스저항(R5, R6)을 통하여 에미터 접지된 트랜지스터(Q3)의 베이스에 연결함과 동시에 트랜지스터(Q3)의 콜렉터를 저항(R7,R8)의 접속점에 연결하여서된 것으로써 이러한 본 고안 구성의 전체적 작동은 수직신호 입력단자(1)에 입력단 수직신호가 편향요크코일(L1)을 통하여 부궤환 저항(R1,VR,VR2)에서 얻은 부궤환 전압을 수직구동 및 수직발진기(2)에 부궤환하여 화면수직크기를 가변하는 것이다.Referring to FIG. 1, the device of the present invention is configured such that the vertical signal input terminal 1 is connected to one side of the deflection yoke coil L 1 through a coupling capacitor C 1 , and the other side of the deflection yoke coil L 1 is connected. Through the variable resistors VR 1 and VR 2 and the resistor R 1 , the movable members of the variable resistors VR 1 and VR 2 are collectors of the transistors Q 1 and Q 2 through the resistors R2 and R3. And emitters of transistors Q 1 and Q 2 are commonly connected to the vertical drive and vertical oscillator 2, with the base of transistor Q 1 connected via resistors R 7 and R 8 to the power supply Vcc. ), The base of the transistor Q 2 is connected to the mode signal input terminal 3 through the resistor R 4 , and the mode signal input terminal 3 is connected via the bias resistors R 5 and R 6 . emitters such as the present write hayeoseo connected to the connection point of the connection to the base of the grounding transistor (Q 3), and at the same time the collector of the transistor (Q 3) resistors (R 7, R 8) No overall operation of the configuration, negative feedback resistor (R 1, VR, VR 2 ) negative feedback voltage to the vertical drive and vertical oscillator obtained from the input vertical signal to the vertical signal input terminal (1) via a deflection yoke coil (L 1) It is negative feedback to (2) to change the screen vertical size.

따라서 모드신호 입력단자(3)에서 입력되는 모드신호가 있는 경우에 트랜지스터(Q2)에는 바이어스 전압이 걸리지 않으므로 트랜지스터(Q3)는 저항(R5, R6, R8) 및 전원(Vcc)에 의해 바이어스가 걸리므로 도통된다.Therefore, when there is a mode signal input from the mode signal input terminal 3, the transistor Q 2 does not apply a bias voltage, so that the transistor Q 3 has a resistor R 5 , R 6 , R 8 and a power supply Vcc. It is biased by, so it conducts.

따라서 트랜지스터(Q3)의 콜렉터는 로우레벨이 되고 이에 따라 트랜지스터(Q1)는 도통된다.Thus, the collector of transistor Q 3 is at a low level, thereby transistor Q 1 is conductive.

따라서 가변저항(VR1)을 통하여 수직신호입력단자(1)에 입력된 수직신호는 저항(R2)과 트랜지스터(Q1)의 콜랙터에미터를 통하여 수직구동 및 수직발진기(2)에 공급이 된다.Therefore, the vertical signal input to the vertical signal input terminal 1 through the variable resistor VR 1 is supplied to the vertical drive and the vertical oscillator 2 through the collector emitter of the resistor R 2 and the transistor Q 1 . Becomes

이때 수직 신호는 가변 저항(VR1)을 통하게 되므로 수직크기의 조절이 가능하게 된다.At this time, since the vertical signal is passed through the variable resistor VR 1 , the vertical size can be adjusted.

또한 모드신호입력단자(3)에 모드신호가 입력되지 않으면 트랜지스터(Q2)가 도통되고 동시에 트랜지스터(Q3)의 베이스에 바이어스 전압이 걸리지 않게 되어 트랜지스터(Q3)가 비도통된다.Also, if the mode signal input terminal 3 to a mode signal is input transistor (Q 2) is not conductive, and at the same time a bias voltage to the base of the transistor (Q 3) takes is a non-conductive transistor (Q 3).

따라서 전원(Vcc)이 저항(R7, R8)을 통하여 트랜지스터(Q1)의 베이스에 인가되므로 트랜지스터(Q1)가 비도통되므로 수직신호 입력단자(1)에 입력된 수직신호는 가변저항(VR2) 저항(R3) 및 트랜지스터(Q2)의 콜렉터에 미터를 통하여 수직구종 및 수직발진기(2)에 공급된다.Therefore, since the power supply Vcc is applied to the base of the transistor Q 1 through the resistors R 7 and R 8 , the transistor Q 1 is not conducting, so the vertical signal input to the vertical signal input terminal 1 is a variable resistor. (VR 2 ) The resistors R 3 and the collectors of the transistors Q 2 are supplied to the vertical bulb and the vertical oscillator 2 through a meter.

이 때에도 모드 신호가 단자(3)에 입력되어 트랜지스터(Q1)가 도통되는 경우와 같이 수직신호는 가변저항(VR2)에 의하여 가변될 수 있어 수직크기의 조절이 가능한 것이다.In this case, as in the case where the mode signal is input to the terminal 3 and the transistor Q 1 is conducted, the vertical signal may be changed by the variable resistor VR 2 , and thus the vertical size may be adjusted.

이상에서 설명한 바와 같이 본 고안 장치에 의하면, 두종류의 수직동기신호가 입력될 때 모드신호가 없는 경우(로우레벨)에는 가변저항(VR2)으로써 그리고 모드신호가 있는 경우가 (하이레벨)에는 가변저항(VR1)으로서 수직동기신호를 조절하여 수직크기를 가변할 수 있는 것이므로 이중 수직동기신호는 입력에 따라 모니터 장치의 화면크기를 일정하게 하여 항상 화면 전체 내용을 훼손됨이 없이 모니터 화면에 나타낼 수 있는 것이다.As described above, according to the device of the present invention, when there are no mode signals when two types of vertical synchronization signals are input (low level), the variable resistor VR 2 is used, and when there is a mode signal (high level). Since the vertical size can be changed by adjusting the vertical synchronization signal as the variable resistor (VR 1 ), the double vertical synchronization signal is used to make the screen size of the monitor device constant according to the input so that the entire screen is always displayed on the monitor screen without being damaged. It can be.
