To run.

  When the cars 4 to 4G stop at the service floor, a door open / close signal is transmitted from the group management control device 3 to the door control devices 11 to 11G to open and close the doors 10 to 10G. That is, the doors 10 to 10G are automatically opened, and the doors 10 to 10G are automatically closed when a certain period of time elapses after the doors 10 to 10G are fully opened. In addition, when an elevator user in the car pushes the door closing buttons 12 to 12G provided in the cars 4 to 4G, a signal is transmitted to the group management control device 3, and the group management control device 3 performs door control. A door closing signal is transmitted to the devices 11 to 11G, and the doors 10 to 10G are closed before a predetermined time elapses.

  However, the destination floor call arrival detection means 7 detects that the car to which the destination floor call has been assigned has arrived at the floor to which the landing call has been registered prior to the car to which the landing call has been assigned. Then, the landing call canceling means 8 on the first arrival is operated to cancel the registration of the landing call, and the door closing button invalidating means 9 closes the doors provided in the cars 4 to 4G to which the destination floor calls are assigned. Even if the buttons 12 to 12G are pressed, the door closing buttons 12 to 12G are disabled for a certain period of time, and the car doors 10 to 10G to which the destination floor call is assigned are kept open for a certain period of time. . For example, as shown in FIG. 3, when an elevator customer A presses the landing button 18-10F in the elevator hall on the 10th floor, a response to the landing call is reserved in the car 4C of Unit 4 and reserved. It is assumed that the elevator passenger A is waiting for the arrival of the car 4C in front of the car 4C of No. 4 because the lamp 19-10C is lit. Here, if the 4th car 4D arrives at the 10th floor elevator hall by the destination floor call before the 4th car 4C arrives at the 10th floor elevator hall, the first landing landing call canceling means 8 When the elevator call A is cancelled, the door closing button 12D of the car 4D of the fifth car is disabled by the door closing button invalidating means 9 for a certain period of time. Therefore, even if the elevator passenger B in the passenger car 4D of Unit 5 presses the door closing button 12D, the door 10D does not close before the fixed time elapses, so it waits in the elevator hall on the 10th floor. Elevator passenger A can now reliably enter the car 5D of the fifth car.

  Whether or not it is detected by the destination floor call arrival detection means 7 that the car to which the destination floor call is assigned has arrived at the floor to which the hall call is registered prior to the car to which the board call is assigned This determination, that is, the determination of destination floor call arrival is performed for all floors of elevators 2 to 2G in the following procedure.
