  Transmission devices 70 and 72 are fixed to the vertical members 126 on the upper floor side and the lower floor side in the skirt guard 44.

  The upper floor side skirt guard sandwiched detection device 681 is connected to the upper floor side transmission device 70 by a branch wiring 701 made of a cord or a cable, and the upper floor side sandwiched detection device 682 is a cord or a cable or the like. Are connected by a branch wiring 702 consisting of a cord or a cable, and a step chain disconnection detecting device 684 on the upper floor is connected by a branch wiring 704. Yes. Further, the front skirt guard 40 on the upper floor boarding board 32 is provided with a passenger detection sensor 78 for detecting passengers getting on and off the upper floor. The passenger detection sensor 78 is a photoelectric sensor, such as a cord or a cable. The branch wiring 760 is connected to the transmission device 70 on the upper floor side.

  The lower floor side skirt guard sandwiched detection device 681 is connected to the lower floor side transmission device 72 by a branch wiring 721 made of a cord or a cable, and the lower floor side sandwiched detection device 682 is a cord or a cable or the like. Are connected by a branch wiring 722, a lower floor side step abnormality detection device 683 is connected by a branch wiring 723, and a lower floor side step chain disconnection detection device 684 is connected by a branch wiring 724 made of a cord or a cable. Yes. Further, the front skirt guard 42 on the lower floor boarding board 34 is provided with a passenger detection sensor 78 for detecting passengers getting on and off the lower floor. The passenger detection sensor 78 is a photoelectric sensor, such as a cord or a cable. Is connected to the transmission device 72 on the lower floor side by a branch wiring 780 consisting of

  The transmission device 72 on the lower floor side and the transmission device 70 on the upper floor side are connected by a single main wiring 74 made of a cord or a cable, and the transmission device 70 on the upper floor side and the control device 50 in the machine room 14 are connected to each other. Are connected by a main wiring 76 made of a cord or a cable. That is, the transmission device 72, the transmission device 70, and the control device 50 are connected in series by the main wiring 74 and the main wiring 76. The main wiring 74 is wired inside the skirt guard 44.

  When the limit switch of each safety device 68 is turned ON or OFF, the operation signal is input to the upper floor transmission device 70, and when the passenger gets on and off the upper floor, the operation signal is input from the passenger detection sensor 78. . The transmission device 70 adds the identification information of each safety device 68 or the passenger detection sensor 78 to the operation signal from each safety device 68 and the passenger detection sensor 78, and outputs it to the control device 50.

  Similarly, when the limit switch of each safety device 68 is turned ON or OFF, the operation signal is input to the lower floor side transmission device 72, and the operation signal is input from the passenger detection sensor 78 when the passenger gets on and off the lower floor side.
