Abstract
A touch screen device includes: a touch screen that includes an operation surface on which touch operations are performed, and in which capacitances change at regions of the operation surface touched by conductors; a pressure sensor unit to output a signal corresponding to a pressing value of a pressing force applied to the operation surface; and a controller to calculate coordinates indicating positions of the touch operations on the operation surface based on the capacitances. The touch operations include first and second touch operations. The controller determines touch operation information input by the second touch operation to be valid when a condition is satisfied, and determines the touch operation information to be invalid when the condition is not satisfied. The condition is that the first touch operation is being performed and a pressing value of a pressing force of the first touch operation is within a predetermined reference pressure range.
