Abstract
A pressing sensor is provided that generates an output voltage of a first polarity by deforming with an operation plate when a part of a user's body touches the operation plate, and generates the output voltage of a second polarity by deforming with the operation plate when the part of the user's body is moved away from the operation plate. Moreover, a calculation unit calculates an electrical parameter integral value by time-integrating an electrical parameter that changes with the output voltage generated by the pressing sensor. The electrical parameter has a third polarity when the output voltage has the first polarity and has a fourth polarity when the output voltage has the second polarity. The calculation unit calculates a subtraction electrical parameter integral value obtained by subtracting a predetermined value having the third polarity per unit time from the electrical parameter integral value.
