Japanese Patent JPH0439091
Kind Code:
B2
Abstract:
PURPOSE:To attain the accurate detection of an input position on an analog touch panel by connecting one side through a switch too a first constant voltage source for a pair of conductive films respectively and connecting the side facing to one side through a parallel connection with a voltmeter and the resistance having a prescribed resistance value to a second constant voltage source. CONSTITUTION:One side 2X of a pair of electric conduction films is constituted so as to have electrodes 22X and 23X on two sides facing to the X direction and impress the voltage in an X direction, and other side 2Y of a pair of films is constituted so as to have electrodes 22Y and 23Y on the two sides facing to the Y direction and impress the voltage in the Y direction. One side 22X or 22Y of the electrode held a pair of films 2X and 2Y respectively is connected through a switch 1X or 1Y to a constant voltage source 6. Other 23X or 23Y of the electrode is grounded through a parallel connection with a voltmeter 3X or 3Y and a resistance 4X or 4Y having a prescribed resistance value respectively. Thus, the input position detecting circuit of the analog touch panel to improve the accuracy of the position input in analog type touch panel can be obtained.
