본 고안의 여러개의 터치센서를 사용하는 터치감지회로에 적합한 전자식 터치센서 감지회로에 관한 것이다. 종래의 터치감지회로는 각각의 터치센서 감지회로마다 각각의 발진회로가 접속되어 있어 다수개의 터치감지회로를 구성하는 경우에는 회로 구성이 복잡하여 질 뿐만아니라 제조원가의 앙등을 초래하는 것이었다.An electronic touch sensor sensing circuit suitable for a touch sensing circuit using a plurality of touch sensors of the present invention. In the conventional touch sensing circuit, each oscillation circuit is connected to each touch sensor sensing circuit, and when a plurality of touch sensing circuits are configured, not only the circuit configuration is complicated but also the manufacturing cost rises.

본 고안은 이와 같은 점을 감안하여 다수개의 터치감지 회로를 구성하는 경우에 단일의 발진회로로서 구동할 수 있게하여 회로의 단순화를 기할 수 있게한 것으로 이를 첨부도면에 의하여 상술하면 다음과 같다. 제1도는 본 고안의 회로도로써 트랜스(T)에서 다이오드(D)와 콘덴서(C1)를 통하여 정류하도록 구성하여 발진회로(OSC)에 연결구성된 각각의 터치감지회로(S)(S')에 전원을 공급할 수있게 구성하고, 단일의 발진회로(OSC)에 연결구성된 각각의 터치감지회로(S)(S')는 모두 동일하게 구성된것으로 터치감지회로(S)(S')는 각각 터치센서(TH),(TH')에서 콘덴서(C2)(C2')를 통하여 연결된 트랜지스터(Q3)(Q3')의 에미터측에 트랜지스터(Q2)(Q2')의 에미터측을 연결 구성한 후 트랜지스터(Q2,Q3),(Q2',Q3')의 베이스측에는 트랜지스터(Q1)(Q1')의 콜렉터측을 연결 구성시켜된 것이다.In view of the above, the present invention enables driving as a single oscillation circuit when configuring a plurality of touch sensing circuits, thereby simplifying the circuit. This will be described in detail with reference to the accompanying drawings. 1 is a circuit diagram of the present invention, which is configured to rectify through a diode (D) and a capacitor (C 1 ) in a transformer (T) and is connected to each touch sensing circuit (S) (S ') configured to be connected to an oscillation circuit (OSC). Each touch sensing circuit (S) (S ') configured to supply power and connected to a single oscillation circuit (OSC) is configured identically, and each touch sensing circuit (S) (S') is a touch sensor. (TH), (TH ') to the emitter teocheuk of (connected transistors (Q 3) (Q 3' ) to the emitter teocheuk transistor (Q 2) of the (Q 2 ') via a capacitor (C 2) C 2) in the " After the connection configuration, the collector side of the transistors Q 1 and Q 1 ′ is connected to the base side of the transistors Q 2 , Q 3 and Q 2 ′ and Q 3 ′.

이와 같이 구성된 본 고안은 트랜스(T)에서 다이오드(D1)와 콘덴서(C1)를 통하여 정류된 직류전원이 각각의 회로에 공급되면 통상의 발진회로(OSC)는 발진동작하여 신호를 저항(R1)을 통하여 트랜지스터(Q1)의 베이스에 인가시키게 되므로 트랜지스터(Q1)는 도통 및 차단 동작을 반복하게 된다.According to the present invention configured as described above, when the DC power rectified through the diode D 1 and the capacitor C 1 is supplied to each circuit in the transformer T, the general oscillation circuit OSC oscillates and resists the signal. R 1) thereby so applied to the base of the transistor (Q 1) through the transistor (Q 1) is conductive and to repeat the breaking operation.

따라서 트랜지스터(Q1)이 차단되면 저항(R2)을 통하여 트랜지스터(Q2)를 도통시키고, 트랜지스터(Q1)가 도통될 때에는 트랜지스터(Q3)의 베이스가 저전위 상태가 되어 트랜지스터(Q3)가 도통하게 된다. 따라서 트랜지스터(Q1)가 도통 및 차단을 반복할때 트랜지스터(Q2)(Q3) 역시 도통 및 차단을 반복하게 되어 출력단자(OUT)에는 항상 고전위 상태의 전압이 제3도에서와 같이 나타나게 된다.Accordingly, when the transistor Q 1 is cut off, the transistor Q 2 is conducted through the resistor R 2 , and when the transistor Q 1 is turned on, the base of the transistor Q 3 is in a low potential state, so that the transistor Q 3 ) becomes conductive. Therefore, when the transistor Q 1 repeats conduction and interruption, the transistors Q 2 and Q 3 also repeat conduction and interruption, so that the voltage of the high potential state is always present at the output terminal OUT as shown in FIG. Will appear.

이때에 터치센서(TH)를 조작하게 되면(터치센서에 인체가 접속되면) 인체를 통한 접지점이 콘덴서(C2)와 연결되어 트랜지스터(Q2)가 도통될 때 저항(R3)을 통한 전류가 콘덴서(C2)에 충전되고, 트랜지스터(Q3)가 도통될 때 콘덴서(C2)에 충전된 전원이 트랜지스터(Q3)를 통하여 방전하게되어 출력단자(OUT)의 전압은 제2도와 같은 파형이 인가하게 되는 것이며, 터치센서(TH)의 접촉시에 그 터치 여부를 감지할 수 있는 전자식 터치센서 감지회로를 제공할 수가 있는 것으로, 다수의 터치감지회로(S')를 연결설치하여 구성시켜도 동일한 효과를 기할 수 있는 것이다.At this time, when the touch sensor TH is manipulated (when the human body is connected to the touch sensor), a ground point through the human body is connected to the capacitor C 2 so that the current through the resistor R 3 when the transistor Q 2 is conducted. Is charged in the capacitor C 2 , and when the transistor Q 3 is conducted, the power charged in the capacitor C 2 is discharged through the transistor Q 3 , so that the voltage at the output terminal OUT is shown in FIG. The same waveform is to be applied, and it is possible to provide an electronic touch sensor sensing circuit that can detect whether the touch is touched by the touch sensor TH, by connecting and installing a plurality of touch sensing circuits S '. The same effect can be achieved even if configured.
