이 발명은 전자펜(Stylus)에 관한 것으로 더욱 상세하게 말하자면, 패널(Panel)에 유기되는 전압과 전류를 증가시키기 위하여 복수의 팁을 사용하여 안전성, 정확도 및 해상도(Rsolution)를 향상한 전자펜 시스템에 관한 것이다.The present invention relates to an electronic pen (Stylus). More specifically, the electronic pen system improves safety, accuracy, and resolution by using a plurality of tips to increase voltage and current induced in a panel. It is about.

요즈음 펜(Pen)컴퓨터나 캐드(Cad)용 마우스등에 전자펜이 널리 사용되고 있는 추세이다, 종래의 전자펜에 관한 기술로는 미합중국 특허 제4,695,680호 "특허일: 1987년 9월 22일의"(STYLUS FOR POSITION RESPONSIVE APPARATUS HAVING ELECTROGRAPIC APPLICATION)에 기재된 것이 있다.Nowadays, electronic pens are widely used in pen computers and CAD mice. As a technology related to a conventional electronic pen, US Pat. STYLUS FOR POSITION RESPONSIVE APPARATUS HAVING ELECTROGRAPIC APPLICATION.

제1도는 일반적인 종래 전자펜 시스템의 사용 실시예를 도시한 단면도로서 그 구성은, 신호를 발생하는 신호원(1)과 신호를 전달하는 팁(2)과 팁(2)을 감싸는 팁 보호체(3)로 이루어 지는 전자펜(4)과; 유전체층(5)과 저항체층(6)으로 이루어지는 센서부(8)와; 센서부(8)에 양방향으로 연결되어 있는 신호처리부(7)로 이루어진다.1 is a cross-sectional view showing an embodiment of the use of a conventional conventional electronic pen system, the configuration of which is a signal source 1 for generating a signal, a tip 2 for transmitting a signal, and a tip protector surrounding the tip 2 ( An electronic pen 4 made of 3); A sensor unit 8 composed of a dielectric layer 5 and a resistor layer 6; The signal processing unit 7 is connected to the sensor unit in both directions.

상기한 구성을 따르는 종래 전자펜 시스템의 작용은, 전자펜 사용자에 의해 전원이 인가되면 동작이 시작된다.The operation of the conventional electronic pen system according to the above configuration starts when the power is applied by the electronic pen user.

동작이 시작되면, 신호원(1)에서 신호가 출력되고, 출력된 신호는 팁(2)과 팁 보호체(3)를 통과하면서 전장을 형성하여 센서부(8)에 신호를 인가한다. 인가된 신호는 유전체층(5)과 저항체층(6)을 통해 신호처리부(7)로 들어간다.When the operation is started, a signal is output from the signal source 1, and the output signal passes through the tip 2 and the tip protector 3 to form an electric field to apply a signal to the sensor unit 8.
