Abstract: A measuring device for measuring an inspection target on the basis of vibration generated when the inspection target has been irradiated with laser light includes a condensing position deriving portion configured to derive an amount of adjustment of a distance between condensing lenses of a laser condensing unit configured to condense the laser light on the basis of a distance between a laser device configured to radiate the laser light and an irradiation location of the laser light and a communicating portion configured to transmit control information including information representing the amount of adjustment to the laser condensing unit.

Abstract: An elevator passenger car allows enhancement of rigidity of a lower beam with a simple configuration while suppressing an increase in the number of components, and includes an upper beam disposed at an upper side, a pair of vertical frames having upper ends connected to both ends of the upper beam, a lower beam disposed between lower ends of the pair of vertical frames while having both ends connected, and a pair of underfloor side surface beams which are mounted and connected onto both ends of the lower beam while extending orthogonal thereto. The elevator passenger car has a car room disposed at a part defined by the upper beam, the pair of vertical frames, and the lower beam that is mounted on the pair of underfloor side surface beams. An underfloor side surface beam reinforcing member is provided for each of the pair of underfloor side surface beams.
