Abstract
The input operation recognizing section 13 recognizes an input operation to execute re-search in the operating section 4. The facility search control section 10 makes the facility search section 9 execute re-search. The re-search by the facility search section 9 is carried out by searching, from facilities belonging to the same group as that of those detected in the previous search, facilities other than those detected in the previous search. With the present invention, when the re-search as described above is to be performed, user's operation for specifying a facility is not required, which improves the convenience in facility search.
