Abstract
Detection of complex input by two touched points are enabled to be detected by a resistive film type touch panel input device equipped with two resistive films facing each other with a minute gap therebetween; a first electrode pair; a second electrode pair extending in directions perpendicular to the first electrode pair; means for applying voltages between the first electrode pair and between the second electrode pair; means for measuring the voltage which is divided at two touch points with respect to the first electrode pair and the second electrode pair, when the resistive films are caused to contact each other by being touched at two points; means for measuring currents that flow between the first electrode pair and between the second electrode pairs when the touch occurs; and discriminating means, for discriminating the trajectories of the two touch points based on the values of the measured voltages and currents.
