Abstract

PROBLEM TO BE SOLVED: To prevent occurrence of such an accident that a hand of a passenger is caught between hall doors, or is caught in a gap between the hall doors and a hall frame. SOLUTION: A light projector 11a and a light receiver 11b for detecting an obstacle are provided between hall doors 2 and a hall frame 9, and a speaker for issuing voice by which attention is attracted is provided in the upper part of the hall frame 9. With this arrangement, a light beam 14 from the projector 11a is blocked by a hand of a passenger if the hand is caught when the pair of doors are closed, and accordingly, the hand of the passenger can be detected so that a signal for reopening the doors 1, 2 is delivered. Further, if a passenger waiting for a car to arrive at in the hall 8 extends his hand to the hall doors 2, the light 14 is blocked by the hand, and accordingly, a signal for inhibiting the opening operation of the doors 1, 2 is delivered and voice such as a message for attracting attention is issued from the speaker.
