Abstract: A trigger switch according to one or more embodiments may include a first conductive plate (movable electrode) movable in response to movement of a trigger receiving a depressing operation, and a second fixed electrode (fixed electrode) located adjacent to a movable range of the first conductive plate with a space in between. The second fixed electrode forms a capacitor together with the first conductive plate. The capacitor formed by the first conductive plate and the second fixed electrode has a capacitance that changes as the first conductive plate moves.

Abstract: A dimension measurement device provided with a flat plane that forms the xy plane of a Cartesian coordinate system comprising x, y and z axes and with an x-axis direction measurement unit, y-axis direction measurement unit and z-axis direction measurement unit, wherein the axial direction measurement units each have an array of a plurality of light emitting/receiving unit boards (30), which include a plurality of pairs of light-emitting elements and light-receiving elements and a shift register, and the axial direction measurement units have controllers (51, 52, 53); for controlling the shift registers so as to scan through the light-emitting elements and light-receiving elements lined up in the axial directions and calculating the dimensions of the freight in each of the axial directions on the basis of the output of the light receiving elements. Each controller (51, 52, 53) performs scanning at the same time.

Abstract: The coil that is installed on a lever is obtained from a flat coil, which is wound flat so as to generate upper and lower winding regions that are parallel to the direction that the lever extends along a vertical surface that is parallel to the direction that the lever extends. The magnetic circuit is provided with multiple plate-shaped permanent magnets that face the upper and lower winding regions of the flat coil and are magnetized in a direction that is orthogonal to the vertical surface, and yoke members that induce lines of magnetic force of the permanent magnets so that a magnetic flux of an orientation that is orthogonal to the vertical surface is generated.
