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.

A movement member which reciprocates includes a thick portion and a thin portion, a bearing portion formed in the thick portion is slidingly supported by the guide shaft, and a sliding portion formed in the thin portion is slidingly guided by the sliding guide portion. Power of the motor is transmitted to a pinion gear via a speed reduction gear and a speed reduction mechanism inside a gear box, and a movement reaction force is applied from the pinion gear to the rack portion. Since the rack portion is positioned on an axis Os, a force is effectively applied to the movement member by the power from the motor.
