Abstract: A load sensor includes: a base member; an electrically-conductive elastic body having a band-like shape and disposed on a surface of the base member; an electrically-conductive member disposed so as to be superposed on the electrically-conductive elastic body; a dielectric body provided between the electrically-conductive elastic body and the electrically-conductive member; and a substrate configured to connect the electrically-conductive elastic body and an external circuit. The substrate includes an electrode extending in a width direction and a length direction of the electrically-conductive elastic body, and is fixed to the base member in a state where the electrode is pressed against a surface of the electrically-conductive elastic body.

Abstract: A load sensor includes: an element part in which capacitance changes in accordance with a load; a copper wire drawn from the element part in order to detect change in the capacitance; and a fixation tool configured to fix the copper wire to the element part. The element part includes an electrically-conductive elastic body that is electrically conductive and that forms one pole for the capacitance, and the fixation tool presses and fixes the copper wire to a surface of the electrically-conductive elastic body so as to be movable with respect to the surface of the electrically-conductive elastic body in accordance with elastic deformation of the electrically-conductive elastic body.

Abstract: An image display device includes: a light source emitting laser light; a screen on which an image is drawn by being two-dimensionally scanned by the laser light; a scanner causing the laser light to scan the screen; a light detector detecting a light amount of the laser light emitted from the light source; and a controller controlling the light source by changing a current value to drive the light source in response to a target light amount. The controller obtains a detection signal when driving the light source at a plurality of current setting values from the light detector, and corrects the current value with respect to the target light amount according to an arithmetic operation configured to suppress a difference between an output characteristic of the light source guessed by the obtained detection signal and a reference output characteristic.
