  • the light projected by the light projecting unit 12A of the infrared sensor 12 passes through the filter unit 14A (see FIG.
  • the infrared sensor having the detection area AR is in a normal state (a state in which the infrared sensor 12 is not covered by the jig 14) different from the state shown in FIG. 10A.
  • 12 outputs a signal used for opening / closing control of the sliding door 11 of the automatic door device 1.
  • the infrared sensor 12 outputs the control information of the infrared sensor 12 including the amount of reflected light from the jig 14.
