A detection device is configured to detect an electrostatic capacitance between an operated member having a plurality of detection areas and an electrode having areas associated with the detection areas respectively. A control device is configured to determine whether an operation is performed to each of the detection areas based on whether a difference between the electrostatic capacitance and a reference electrostatic capacitance exceeds a threshold range, and to change the reference electrostatic capacitance based on a change in the electrostatic capacitance. The control device holds the reference electrostatic capacitance in a case where different changes in the electrostatic capacitance are detected between the detection areas.
