Abstract (en)

[origin: EP2075210A1] First and second detected bodies that are disposed so as to be spaced apart from each other in a direction of movement of a car are disposed at a first position that is either inside a hoistway or on the car, and first and second detectors are disposed at a second position. The first detector has a magnetic sensor on which a first detecting region is disposed, and the second detector has an optical sensor on which a second detecting region is disposed. Each of the first and second detected bodies can pass through the first and second detecting regions due to the movement of the car. The first detected body is inserted into the first detecting region when the car is within a predetermined door opening and closing enabled zone, and the second detected body is inserted into the second detecting region when the car is within a predetermined car floor alignment zone that is set within the door opening and closing enabled zone. The magnetic sensor can detect only presence or absence of insertion of the first detected body into the first detecting region among the first and second detected bodies. The optical sensor can detect presence or absence of insertion of either of the first and second detected bodies into the second detecting region.
