<p>A subject of a prescribed length to be detected is provided in any one of an elevator shaft and a car and a detector is provided in the other. The detector has a pair of landing position sensors that are arranged at an interval with respect to each other along a moving direction of the car and perform detecting operation by facing the subject to be detected, and a pair of floor position adjusting sensors and a door opening and closing position sensor. The floor position adjusting sensor is arranged between the landing position sensors and the door opening and closing position sensor is arranged between the floor position adjusting sensors. In the detector, any detecting operation of each landing position sensor is stopped when the position of the car is deviated from a prescribed car landing zone, any detecting operation of each floor position adjusting sensor is stopped when the position of the car is deviated from floor adjusting operable zone that is adjacent to the car landing zone, and a detecting operation of the door opening and closing position sensor is stopped when the position of the car is deviated from the door opening and closing zone including the car landing zone and the floor adjusting operable zone.</p> |
