Abstract: A touch panel device includes a touch panel that changes a state of a region on an operation surface in which a touch operation is performed, a pressure sensor unit to output a pressure detection signal corresponding to a pressing force (Fp) applied to the operation surface, and a controller to calculate coordinates of the touch operation on the operation surface based on the state of the touch panel. In a case that a second touch operation is performed, when a value of the pressing force is greater than a predetermined threshold pressing force (ThF), the controller judges that second operation information corresponding to the second touch operation is valid. In a case that a second touch operation is performed, when the value of the pressing force is less than or equal to the threshold pressing force, the controller judges that the second operation information is invalid.

In a case that a first touch operation is performed, the controller judges that first operation information corresponding to the first touch operation is valid. In a case that a second touch operation is performed, when a press value of the pressing force indicated by the pressure detection signal is greater than a predetermined threshold pressing force, the controller judges that second operation information corresponding to the second touch operation is valid. In a case that a second touch operation is performed, when the press value is less than or equal to the threshold pressing force, the controller judges that the second operation information is invalid.
