14 is a door opening relay, 15 is a landing door fully closed detection switch, 17 is a car door fully closed detection switch, and 19 is a fully closed failure detection circuit (landing door fully closed failure detection time relay)
, 19a is a re-closing command circuit (landing door cannot be fully closed detection time relay contact), 20 is a re-closing command circuit (counter), 20a is a door closing ability increasing circuit (counter contact), 25 is a speed command generation circuit, 28 is a door drive motor. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] A car door fully closed detection switch that operates when the car door is fully closed, in a vehicle in which a car door is driven in the closing direction by a door drive motor, and the landing door is also driven in the closing direction in conjunction with the car door. , a landing door fully closed detection switch that operates when the landing door is fully closed, and a fully closed detection switch that detects that the landing door fully closed detection switch does not operate even if the car door fully closed detection switch operates. A detection circuit, a re-door closing command circuit which closes the car door and the landing door when the fully closing failure detection circuit operates, and a re-door closing command circuit which closes the car door and the landing door when the fully closing failure detection circuit operates even if the re-closing command circuit operates. An elevator door control device comprising: a door closing capacity increasing circuit that increases the terminal speed of closing the door.
