ABSTRACT:
In an elevator group control apparatus in which a call by an elevator area call button is assigned to a cage to bring the cage to the user's floor, a second call device is provided separately from the call button. A desired time required for response by cage is designated by the second hall call device, the desired time is compared with an estimated time required for the arrival of car, and a cage is thereby selected to respond to the call. Thus, a cage is caused to serve a user with a minimum time delay.
