<p>An entrance detector (100) disposed at an elevator entrance reads the ID of an elevator user (300) from a personal identification tag (400) and transmits it to an authentication device (600). After authentication processing, the authentication device (600) registers the ID if not registered, and performs call registration of an elevator cab (500). A cab detector (200) in the cab (500) reads the ID from the personal identification tag (400) and transmits it to the authentication device (600). When transmission of the same ID with the registered ID from the cab detector (200) is stopped, the authentication device (600) deletes the registration of the registered ID after the elapse of a fixed time. Therefore, even if the ID is read by means of an entrance detector (100) at an elevator entrance at a destination when the user (300) gets out of the cab (500), the registration of the ID is kept, so that call registration is not performed.</p> |
