  • Patent number: 10620747
    Abstract: A touch type operation input device capable of accurately detecting pressing force with which an operator presses is provided. The touch type operation input device includes a touch panel including a piezoelectric sensor and a touch sensor, and a pressing force detection unit. Until the pressing force detection unit detects a position detection signal given by the touch sensor, the pressing force detection unit causes a reference voltage of the pressing force detection to follow an output voltage of the piezoelectric sensor to be the same as the output voltage of the piezoelectric sensor. When the pressing force detection unit obtains the position detection signal given by the touch sensor, the pressing force detection unit fixes the reference voltage. The pressing force detection unit calculates a pressing force detection voltage from the difference between the output voltage and the fixed reference voltage, and detects the pressing force.
