A lens holder is movably supported by plate springs in a support member provided in a movable unit. Legs of the support member have X direction positioning portions and Y direction positioning portions. Inner facing surfaces of some magnets are in contact with the X direction positioning portions so as to be positioned, and inner facing surfaces of other magnets are in contact with the Y direction positioning portions so as to be positioned. This allows a facing distance to be set without being affected by a variation in thickness among the magnets.

First and second magnetic detection units are disposed at positions where an S/N ratio, which is a ratio between the strength of a magnetic field generated by a current to be measured flowing through a current path and the strength of an external magnetic field, is the same. A processing unit determines a normal operation state in a case where the detection signal of the first magnetic detection unit and the detection signal of the second magnetic detection unit approximately match each other. The processing unit determines that either one of the first and second magnetic detection units has failed in a case where the detection signals do not match each other.

A connection state (conduction/non-conduction) between a slide electrode and a first electrode pattern is switched with a first rotation angle as a boundary, and the switching of the connection state is generated by switching a contact state (contact/non-contact) between a first contact and a first electrode pattern. A connection state between a slide electrode and a second electrode pattern is switched with a third rotation angle as a boundary, and the switching of the connection state is generated by switching a contact state between a first contact and a second electrode pattern. That is, the contact state between the first contact farther away from a rotation center than the second contact and the electrode pattern defines a connection state between the slide electrode and an electrode pattern.

An output of a first sensor having a low sensitivity and an output of the second sensor having a high sensitivity are compared with each other, and thus it is determined whether a physical quantity becomes larger than a maximum value of a physical quantity capable of being measured in the second sensor. A sensor module is provided which is configured to switch a plurality of sensors capable of measuring different ranges and to extend a dynamic range by selecting the output of the second sensor in a selection unit in a case where the output of the first sensor and the output of the second sensor are coincident with each other, and selecting the output of the first sensor in the selection unit in a case where the output of the first sensor and the output of the second sensor are not coincident with each other.

First electrode layers are formed from an ITO layer on one surface of a substrate formed from a PET film. The surfaces of the first electrode layers are covered with an insulating layer formed from a dry film resist or the like. Second electrode layers are formed on the surface of the insulating layer in a printing process. The second electrode layer is formed from conductive nanowires or conductive nanotubes. After that, first wiring layers brought into conduction with the first wiring layers and second wiring layers brought into conduction with the second electrode layers are formed.

Electrodes of a sensor unit are fewer than segments; and, are arranged so that at least one electrode has an overlapping portion in each segment. An element data configuration part repeats processing of correcting a number m of provisional element data on the basis of predetermined information determined in accordance with an electrode pattern and a segment pattern on an operation surface so that a number n of provisional detection data calculated from the number m of provisional element data on the basis of the predetermined information approach a number n of detection data output from a capacitance detection part.

There is provided a wireless sensor device capable of suppressing a reduction in detection sensitivity even if the distance between the wireless sensor device and a detection target is changed. A wireless sensor device 1 includes: a sensor unit 10 that generates a detection signal based on a transmission signal emitted to a detection target 30 and a reflection signal from the detection target of the transmission signal; and a signal processing unit 20 that performs signal processing on the detection signal generated by the sensor unit 10 . The sensor unit 10 generates a first detection signal Sa1 corresponding to a first phase state, which is a phase state of the transmission signal or the reflection signal, and a second detection signal Sa2 corresponding to a second phase state in which a phase of the transmission signal or the reflection signal is different from that in the first phase state. The signal processing unit 20 detects phase information based on the first detection signal Sa1 and second detection signal Sa2, and performs predetermined signal processing based on the detected phase information.
