Abstract (en)
[origin: EP2502870A1] There is provided an elevator door control device that makes detection so as to be capable of judging which of the full open position and the full close position is the position of a door panel by using a position switch provided in only one location along the travel direction of the door panel. For this purpose, an elevator door control device, which controls the opening/closing operation of the door panel which opens and closes an elevator entrance in the right-and-left direction, includes one position switch; first and second light transmitters and first and second light receivers, which are provided on the position switch; a first shield plate and a second shield plate, which are provided on the door panel; and a door control device body that judges, based on a signal carring information about the light receiving state of the first and second light receivers outputted from the position switch, whether or not the door panel lies at the full open position and the full close position. When the door panel is fully opened, the first shield plate shields one or more predetermine light beams of first and second light beams, and when the door panel is fully closed, the second shield plate shields one or more predetermined light beams of the first and second light beams different from the predetermined light beams shielded by the first shield plate.
