Abstract
The invention relates to call registration wherein of a plurality of elevators an elevator which a user (passenger) wants to ride is called to the elevator hall of the user. A display is provided at an elevator hall for users. When a user depresses a hall calling button, a group supervisory controller determines and selects a suitable elevator, and causes the condition of the elevator to be displayed on the display in the form of sentences or the like. If the user is satisfied with the selected elevator, the hall calling button is not actuated again. If the user is dissatisfied with the selected elevator, the hall calling button is depressed again so that the controller selects another elevator for service to the user.
