  Next, in step S102, the camera 13 captures the face image 2B and transfers the image to the personal authentication means 7. The personal authentication means 7 performs personal authentication using the face image 2B. Next, in step S103, it is determined whether or not the personal authentication is successful. If the personal authentication unit 7 fails in the personal authentication, the process enters a standby state in step S104, and the operations in steps S101 to S104 are repeated. If it is determined that the personal authentication is successful, in step S105, the result and the user information are transmitted to the information display control means 8, and the information display control means 8 obtains the name and information from the user information. Information such as the destination floor is acquired and information for display on the screen is synthesized. When the information to be displayed is created, in step S106, the information display control means 8 synthesizes the face information 2B and the created information while continuing to shoot with the camera 13, and displays the synthesized information on the display monitor 10. When the name information as the user is “XXX” and the destination floor is “Δ floor”, a composite screen of the message 10B and the face information 2B as shown in FIG.

  Next, in step S107, the information display control means 8 notifies the elevator control apparatus 3 of the result of successful authentication at the landing hall 9. Next, in step S108, the elevator control device 3 receives the result, generates a call to the floor where the user 2 is located, and moves the car 1a of the elevator 1 to the floor where the user is located. When the elevator car 1a arrives at the floor where the user is present in step S109, when the user 2 gets into the car 1a, the elevator control device 3 acquires the destination floor from the information of the individual 2 as the user. Then, a car call to the destination floor is generated, the call is registered, and the manual processing is completed. Therefore, the user 2 can move to the target floor without doing anything regarding call registration.
