Therefore, even though wireless communication is performed between the control unit 8 and the device to be controlled, the reliability of the communication can be improved.

In addition, when the car 3 in one hoistway group 5 is about to move to the other hoistway group 5, the control unit 8 that centrally controls one hoistway group 5 controls the other hoistway group 5. The control unit 8 that centrally controls the car 3 requests permission for the car 3 to move to another hoistway group 5, and the control unit 8 that centrally controls the other hoistway group 5 requests permission for the car 3 to move to another hoistway group 5. The control unit 8 determines whether or not the car 3 can be accepted, notifies the first hoistway group 5 of permission or prohibition, and centrally controls the first hoistway group 5. The car 3 is configured to be moved to another hoistway group 5 when the car 3 is received. Therefore, when a car 3 is moved from one hoistway group 5 to another hoistway group 5, the other hoistway group 5 on the side that accepts the car 3 determines whether or not it can be accepted. Inconvenience caused by the movement of the car 3 into the interior of the car 3 can be suppressed.

Further, the control unit 8 has an operation mode for centrally controlling the operation of the cars 3 in the hoistway group 5, and a management mode for managing the elevator 1. In the management mode, an input section (a hall call section 62 and a car input section 94) capable of inputting operations related to the operation of the car 3 is provided, and an input section provided in at least one of the hall 6 and the car 3 is used for inputting in the management mode. (car input section 94). Therefore, the control section 8 has an operation mode and a management mode, and the input section can be used for both the operation mode and the management mode, so there is no need to separately provide a management section and an input section for management. Therefore, the elevator 1 can be managed efficiently.
