PROBLEM TO BE SOLVED: To provide a detector capable of setting a determination threshold in response to a detection object being in contact with an operation surface to improve detection accuracy.SOLUTION: A detector includes: a threshold setting unit that sets a speed threshold Von the basis of an increased speed V of a capacitance value D output by a touch switch in response to a detection object and that sets a determination threshold Dfor determining detection of the detection object on the basis of the capacitance value D (t) when the increased speed V has reached a speed threshold Vthrough a maximum increased speed V; and a control unit.SELECTED DRAWING: Figure 2 |
