Problems solved by technology

[0003] However, in electrostatic switches, the detected electrostatic capacitance fluctuates depending on whether the operator wears gloves, individual differences, and the state of the fingertips (sweat, injury), etc.
Therefore, there is a problem that accurate judgment cannot be performed if the threshold value is set to a fixed value.

Abstract

The invention provides an input operation receiving apparatus and a threshold value adjusting method. An input operation receiving apparatus includes a mechanical switch; a capacitance sensor that is provided at a position where an operator comes into contact therewith when the mechanical switch is operated and that detects capacitance; and an adjustment unit that adjusts a threshold value for a contact determination when the capacitance sensor is used as a switch, on the basis of a detection value at a time of operation, the detection value at the time of operation being a detection value of the capacitance sensor when an operation of the mechanical switch is detected.

Description

technical field [0001] The invention relates to an input operation accepting device and a threshold adjustment method. Background technique [0002] Conventionally, a switch (hereinafter referred to as an electrostatic switch) that detects a touch operation by an operator based on a change in electrostatic capacitance has been used. In the electrostatic switch, for example, a threshold is set for the capacitance detected by the capacitance sensor, and when the capacitance increased by the approach of an operator's finger or the like exceeds the threshold, it is determined that a touch operation has been performed. [0003] However, in the electrostatic switch, the detected electrostatic capacitance fluctuates depending on whether the operator wears gloves, individual differences, and the state of the fingertip (sweat, injury), etc. Therefore, there is a problem that accurate determination cannot be performed if the threshold value is fixed. [0004] In connection therewith...
