Abstract: In a non-contact voltage measurement device that can precisely measure an alternating-current voltage with a simple structure, a first capacitor and second capacitor, having mutually correlated capacitances, are respectively formed between a first electrode and a conductor and between a second electrode and the conductor. An alternating-current signal is given between the first electrode and a first reference potential. When a switch is off, a first charge detecting signal matching charges accumulated in the second capacitor by the alternating-current signal is created with the second electrode kept at the first reference potential. When the switch is on, a second charge detecting signal matching charges accumulated in the second capacitor by the alternating-current voltage is created with the second electrode kept at a second reference potential.

Abstract: A degree of approach of an object in positions of a detection surface is periodically detected by a sensor unit, a group of detection data items indicating a result of the detection is generated in every one of cycles. The group of detection data items generated in the sensor unit is acquired in every one of cycles by a detection data acquisition unit. In the error determination unit, it is determined in every one of cycles whether there is an error in the detection operation due to noise based on a degree of a temporal change and a degree of a positional change in the detection data. When it is determined by the error determination unit that there is an error in the detection operation of one cycle, a process of acquiring the detection data generated in the one cycle is skipped in the detection data acquisition unit.

Abstract: A spring piece is formed integrally as part of a drive arm that presses an operational body. The spring piece is disposed between a pressing part at which the drive arm presses the operational body and a linkage part that acts a swinging fulcrum. A contact part between the spring piece and a case is positioned closer to the linkage part than the bend bottom end is. When the drive arm swings from an initial orientation to a completely swung orientation, the spring piece can generate an elastic return force. The elastic return force does not largely increase even when the drive arm swings.
Abstract: In a case where the amplitude of a detection voltage is increased, the amplitude of a drive current flowing in a detection-target capacitor also increases, and thus, the amplitude of a detection current also increases. In this case, the increase in amplitude of the detection current is not directly restricted by the condition of a power supply voltage range enabling a circuit to operate. For this reason, a current conversion ratio of a current output circuit or a capacitance value of a capacitor of a current-voltage conversion circuit is set to an appropriate value so as not to cause a voltage to exceed the power supply voltage range, thereby preventing the amplitude of the detection current from being restricted by the condition of the power supply voltage range. Therefore, it is possible to increase the amplitude of the detection voltage to a maximum within the power supply voltage range.
