The name “place name A”, latitudes “N35 ° 12′53 ″ to 21′53 ″”, and longitudes “E139 ° 2′53 ″ to 20′53 ″” are data on the second line from the top. The name “B store”, the latitude “N35 ° 21′21 ″”, the longitude “N139 ° 13′18 ″”, and the business hours “06:00:00 to 20:00” correspond to each other.

  The data on the first line from the top of the place name / facility update history information is the area of “place name A” (latitudes “N35 ° 12′53 ″ to 21′53 ″”, longitude “E139 ° 2′53 ′). ”To 20′53 ″”), the data does not correspond to the requested place name information “place name A” and the requested date / time information “March 20, 2004”.

  The boundary information corresponding to the requested place name information “place name A” and the requested date and time information “March 20, 2004” is the city name “D city” which is data on the first line from the boundary update history information shown in FIG. The name of the town and village to be configured 1 “A town”, the name of the town and town 2 to be configured “B town”, the city name “G city” which is the third line data from the boundary update history information, the name of the town and village 1 to be configured “H town” ”, The name of the composing village 2“ I town ”, and the name of the composing town“ J town ”.

  Further, the place name / facility information display unit 180 associates the requested place name information, the requested date information, the corresponding place name / facility information, and boundary information, and stores them as display history information 170a. That is, if the place name / facility information display unit 180 receives a notification from the place name input unit 120 or the date / time setting unit 130 that the same requested place name information or requested date / time information has been received, the place name / facility information management server 300 The corresponding place name / facility information and the boundary information are searched from the storage unit 170 without communicating with each other, and the searched information is passed to the display unit 160.

  In this way, the place name / facility information display unit 180 can eliminate the need to communicate with the place name / facility information management server 300, so that the load on the network 50 and the place name / facility information management server 300 can be reduced. .

  Next, an image output from the display unit 160 to the display will be described. 5-8 is explanatory drawing for demonstrating an example of the image which the display part 160 outputs to a display. As shown in FIGS. 5 and 6, even if the information is in the same region, the image displayed on the display differs if the requested date and time information is different. That is, when the requested date and time information is before the merger of A town, B town, and C town, A town, B town, and C town are displayed as shown in FIG. 5, but the requested date and time information is after the merger. Only D city after merger is displayed as shown in FIG.

  Further, as shown in FIGS. 7 and 8, when the requested date and time information is before the D store is closed, the A store, B store, C store, and D store are displayed as shown in FIG. When D is closed, only store A, store B, and store C are displayed as shown in FIG. 8 (not displayed on the display because store D is closed).
