Abstract: An optical-element driving device includes: a holding groove formed in a first fixing part to hold a first supporting part; and a first biasing part including an elastic member and a spacer that are disposed with the first supporting part in the holding groove. The first biasing part biases the first supporting part toward a first movable part by the elastic member via the spacer. The first supporting part includes a pair of ball rows arranged at an interval from each other outside of the first movable part. Each ball row is parallel to an optical axis. The ball rows being held respectively by different ones of a plurality of the holding grooves. The first biasing part biases one of the ball rows obliquely with respect to a formation direction in which one of the holding grooves for holding another one of the ball rows is formed.

Abstract: A push switch contains a circuit substrate, two fixed contacts disposed on the circuit substrate, a dome-shaped spring which is disposed above the two fixed contacts and can be displaced between a first position in which the two fixed contacts are in a non-conductive state and a second position in which the two fixed contacts are in a conductive state and a conductive elastic member disposed on a surface of the dome-shaped spring facing the circuit substrate and having a surface facing the two fixed contacts. At least the surface of the conductive elastic member facing the two fixed contacts has conductivity. When the dome-shaped spring is displaced to the second position, the two fixed contacts are in the conductive state through the conductive elastic member.

Abstract: A distance measuring camera 1 includes a first optical system for collecting light from a subject to form a first subject image, a second optical system for collecting the light from the subject to form a second subject image, an imaging part for imaging the first subject image formed by the first optical system and the second subject image formed by the second optical system, and a distance calculating part 4 for calculating a distance to the subject based on the first subject image and the second subject image imaged by the imaging part S. The first optical system and the second optical system are configured so that a change of a magnification of the first subject image according to the distance to the subject is different from a change of a magnification of the second subject image according to the distance to the subject.
