<p>PURPOSE:To eliminate an error based upon mistouching, habits of a person who performs touch operation, a shift in display position due to the change with time of a CRT, etc. CONSTITUTION:The touch screen device is constituted by providing a touch input position calculating means 4 which calculates a touch input position (xout, yout) by receiving signals indicating the arrangement positions of a light emitting element and a light receiving element having received light shielding by touch input, a memory means 5 which stores the respective coefficients of a calculation expression calculated in the touch input position calculating means 4, and a coefficient correcting means 6 which corrects the respective coefficients stored in the memory means 5 on the basis of the difference between the center position of a touch target and the arrangement positions (xin, yin) of the light emitting element and light receiving element having detected the light shielding by the touch input.</p> |
