する。SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a luminous element which is provided near one of a car door and a landing door and emits a light beam, and is disposed so as to face the luminous element. A light receiver for receiving the light beam, and in a safety device for an elevator door that prevents the door from being closed when light reception is not detected by the light emitter, the light receiver does not detect light. At the time, the door opening button of the operation panel in the car is illuminated.

ある。In FIG. 1, 1 is a car, 2a, 2b
Is a door, a door 2a is provided with a multi-beam door sensor composed of a light emitter 3a that emits light rays, and a door 2b is provided with a light receiver 3b that receives the light rays 5 described above. The multi-beam door sensor operates when at least one of the light beams is shielded, and prevents the door from being closed. Reference numeral 6 denotes a door opening button, 7 denotes a car operation panel, and 8 denotes a side plate.
