Primary passenger sensors are installed in outer decks near the entrance/exit of a pair of balustrades such that the sensor output surfaces point in the direction in which passengers enter, and primary passenger sensors are installed in inner decks near the entrance/exit of the pair of balustrades such that the sensor output surfaces are rotated inward to make a predetermined angle with the direction in which passengers enter, thereby forming a sensing range having a width substantially equal to a spacing W between the pair of balustrades, and a length falling within a predetermined distance from the entrance/exit. By sensing the presence/absence of a passenger within this sensing range, an automatic operation can be performed by accurately sensing only persons who use a conveyor by these sensors. |
