ABSTRACT:
When a plurality of preset buttons among a plurality of buttons provided on a destination call registration panel have been successively depressed in a predetermined sequence and within predetermined time intervals, the presence of a request for a special operation is determined so as to register a call to a specified floor not indicated on the panel. When the request for special operation is not determined, a call to a floor corresponding to a depressed button is registeed as usual. In this manner, the destination floor call registration panel can be used for registering cage calls under normal operation and for instructing special operation without any change.
