You may set the area | region comprised from the mesh in which the map in a facility is included. That is, as shown in FIG. 3C, the area setting unit 202b can scroll the minimum rectangular area including at least the mesh that includes the in-facility map based on the mesh representing the in-facility map. Alternatively, as shown in FIG. 3D, an area composed only of a mesh including the in-facility map may be a scrollable area.

  And the map data transmission part 202c of the map information provision server 200 transmits area setting map data to the terminal device 100 via the network 300 (step SA-5).

  And the map data receiving part 102c of the terminal device 100 receives the area setting map data transmitted from the map data transmitting part 202c of the map information providing server 200 (step SA-6).

Here, the area setting map display unit 102d may display a cursor superimposed on the map display screen in order to clearly indicate the designated position on the screen.

  And the scroll display part 102e of the terminal device 100 acquires the scroll operation signal input via the input part 112 by the user (step SA-8).

  Then, the scroll display unit 102e of the terminal device 100 determines whether or not the received scroll operation signal is a signal that exceeds the region in which the region setting map data can be scrolled (step SA-9).

  When it is determined that the signal does not exceed the scrollable region (step SA-9: NO), the scroll display unit 102e of the terminal device 100 is displayed on the display unit 114 based on the received scroll operation signal. The displayed map display screen is scrolled (step SA-10).

  On the other hand, when it is determined that the signal exceeds the scrollable region (step SA-9: YES), the scroll display unit 102e of the terminal device 100 scrolls the map display screen displayed on the display unit 114. (Step SA-11). Here, the limitation of the scroll display is that the scroll display is performed up to the outer edge of the scrollable region, the subsequent operation may be invalidated, or any scroll operation may be invalidated.
