摘要： A low cost touch sensor can, in conjunction with a detection of an input operation, perform detection related to a pressing force during the input operation. Upper part electrodes of the touch sensor are disposed such that they extend in an X axial direction and are arrayed in a Y axial direction that intersects the X axial direction. Furthermore, each upper part electrode comprises a plurality of upper part resistive films whose end parts in the X axial direction are electrically connected by a connection pattern. Lower part electrodes are disposed opposing the upper part resistive films and comprise lower part resistive films, whose contact surface area with the upper part resistive films varies in accordance with a pressing force that narrows the spacing to the upper part resistive films. A detection device detects contact between the upper part resistive films and the lower part resistive films based on the change in the resistance from the upper part electrodes to the lower part electrodes.

摘要： In a pressure detecting apparatus, a pressure sensor includes a piezoelectric sheet that generates a piezoelectric signal according to a load that is applied. A touch detecting unit detects contact with the pressure sensor. An acquirer acquires a piezoelectric output based on the piezoelectric signal. A rate-of-change calculator calculates a rate of change with respect to time of the piezoelectric output acquired within an arbitrary time range before a touch detection time when the touch detecting unit detects contact with the pressure sensor. An applied pressure calculator calculates applied pressure by correcting the piezoelectric output acquired after an end time of the time range used in the calculation of the rate of change using the rate of change. The apparatus enables precise measurement of applied pressure in a pressure sensor.
