ABSTRACT:
A door device for an elevator is provided with an elevator door for opening/closing a doorway through which an interior of a car communicates with a landing, a distance sensor for continuously detecting a distance from the doorway to a passenger at the landing, a processing device for obtaining a door control command corresponding to information from the distance sensor, and a door control device for controlling a movement of the elevator door based on the door control command from the processing device. Thus, the elevator door can be moved in accordance with the movement of the passenger. Accordingly, the passenger is allowed to board the car more reliably, and a running efficiency of the elevator can be enhanced.
