<P>PROBLEM TO BE SOLVED: To provide an elevator device operating a car responding to catching of foreign matter in an elevator door without unnecessary stop of the car, by preventing reflection of an unnecessary signal from a photoelectric sensor when detecting an article caught in the elevator door, in an operation control of the car. <P>SOLUTION: The elevator device includes: the car 15; a double door 17 of car, opening/closing a car entrance 16; a plurality of photoelectric sensors 21, each of which has a light projector 22 and a light receiver 23 respectively disposed to face a pair of door stop parts facing each other of the car door 17, which outputs a light shielding signal when light from the light projector 22 to the light receiver 23 is shielded, and which are disposed to be separated from each other in a height direction; and an elevator control panel 30 controlling the operation of the car 15 according to the light shielding signal from respective photoelectric sensors 21. The elevator control panel 30 performs a control of returning the car 15 to the last stop floor, when the photoelectric sensors 21 neighboring each other in the height direction sequentially output the light shielding signals during travelling of the car 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
