As shown in FIG. 4, the elevator in the present embodiment is a case where a passenger operates the destination floor registration device 1 to input a destination floor and it is determined that boarding on all the cars in the first lap is inappropriate. When the car 4 assigned to respond to the floor of the operation source in the second lap and after is not scheduled to respond to the floor of the operation source in the first lap, the display device 11 of the destination floor registration device 1 of the operation source The information on the assigned number is displayed immediately after the destination floor registration device 1 is operated.

  In addition, when the passenger inputs the destination floor by operating the destination floor registration device 1 and it is determined that the boarding of all the cars in the first lap is inappropriate, the response is made to the floor of the operation source after the second lap. If the car 4 assigned to be responding to or scheduled to respond to the floor of the operation source in the first lap, the car 4 passes after the door closing at the floor of the operation source is completed. Until, the message “Please wait for a while” is displayed on the display device 11 of the operation source destination floor registration device 1 together with the destination floor information, and after passing, the information on the destination floor and the message of the standby instruction are displayed. Instead, the information on the assigned number machine is displayed on the display device 11.

  By the way, although the car 4 assigned to respond to the floor of the operation source in the second lap and after is responding to or scheduled to respond to the floor of the operation source in the first lap, this car When the information on the assigned number is displayed on the display device 11 of the destination floor registration device 1 before the operation 4 passes through the floor of the operation source, the passenger who is scheduled to get on the floor from the operation source You will be guided in front of the boarding gate.

  However, when the car 4 assigned to respond to the floor of the operation source after the second lap is responding to or scheduled to respond to the floor of the operation source in the first lap, the car 4 is If the information of the assigned car is not displayed on the display device 11 of the operation source destination floor registration device 1 until it passes through the operation source floor, passengers scheduled to board from the operation source floor are in the second and subsequent laps. The information on the car number of the car 4 assigned to respond to cannot be grasped until the car 4 passes through the floor of the operation source. Therefore, as described above, the ride of the car assigned to respond to the floor of the operation source after the second lap, even though the boarding of all the cars in the first lap is inappropriate. Since there is no need to guide in front of the mouth, unnecessary guidance to passengers can be prevented.

  As described above, in the elevator according to the first embodiment, the passengers on the floor of the operation source of the destination floor registration device at the landing of each floor are able to board each of the plurality of cars in the congestion of the car. If it is determined that it is inappropriate to board all of the cars, it will pass through the floor of the operation source and then the floor of the operation source. If the assigned car is scheduled to respond to the floor when the assigned car first approaches the floor of the operator, the assigned car will be connected to the floor of the operator. The waiting instruction is displayed on the display device of the destination floor registration device of the operation source until the departure is completed after the response is completed, and after the assigned car leaves the floor of the operation source, the assigned car number Information is displayed on a display device. Therefore, since the useless response of the car can be prevented, the improvement of the operation efficiency of the elevator is not hindered.
