<p>PURPOSE:To provide a resistance film type pen input personal computer which can improve the operability of a pen type input device at input time. CONSTITUTION:A control part 1h processes information on voltages on an upper resistance film 1a sensed from sense parts at two places by A/D converters 1f, 1g and detects variation in the thickness of the tip of the pen type input device 1e to recognize whether or not the button 1j of the pen input device 1e is pressed. Consequently, when the voltages from the sense parts at the two places are different, it is recognized that the button 1j of the pen type input device 1e is pressed and when the voltage from the sense parts at the two places are equal, it is recognized that the button 1j of the pen input device 1e is not pressed.</p> |
