Abstract

목적: 펜입력에 의한 좌표입력장치에 있어서, 외란노이즈나 불필요한 정전용량 결합에 의한 잘못된 좌표입력검출이 행해져버리는 것을 방지한다.Purpose: In a coordinate input device by pen input, it is possible to prevent incorrect coordinate input detection due to disturbance noise or unnecessary capacitance coupling.

구성: 입력펜(6)의 선단을 돌출방향으로 이동가능하게 하고, 태블flt(1)에 접촉되어 가압된 상태의 스위치(6b)를 오프(=펜입력동작 온)로 한다. 그리고, 스위치(6b)를 온(=펜입력동작 오프)으로 할 때는 저항(6c)을 삽입하여 피크검출부(10)에 대한 입력 임피던스가 저하되게 한다. 또, 피크검출부(10)는 공급되는 좌표검출용 신호를 임계값(Vth)과 비교하여 이를 초과할 경우에만 피크검출신호가 출력되게 한다.Configuration: The tip of the input pen 6 is movable in the protruding direction, and the switch 6b in the pressed state in contact with the tablet flt 1 is turned off (= pen input operation on). When the switch 6b is turned on (= pen input operation off), the resistor 6c is inserted to lower the input impedance to the peak detector 10. In addition, the peak detection unit 10 compares the supplied coordinate detection signal with a threshold value Vth so that the peak detection signal is output only when the peak detection signal is exceeded.
