[0037]FIG. 1 shows a data network system, which uses the first embodiment of the data terminal device. As shown in FIG. 1, the data network system 100 comprises a portable telephone set 20 as data terminal device, a base station 12 accessible by the portable telephone set 20, an artificial satellite 13 for transmitting GPS (global positioning system) radio waves, and a position data server 14 for storing detailed map data such as map data for walking people, e.g., crossroads, walking road bridges and underground roads. As shown in FIG. 1, the base station 12 and the position data server 14 are interconnected via a network 15 (such as an internet system).
[0039]FIG. 2 is a block diagram showing the arrangement of the portable telephone set 20. As shown in the Figure, the portable telephone set 20 includes a CPU 21 for controlling the operations of various parts of the portable telephone set 20, a GPS receiving part 22 for receiving GPS radio waves from the artificial satellite 13, a map data part 23 for storing road map data to be used for road map display, a portable telephone wireless part 24 for executing transmission and reception of data with respect to the base station 12, a memory 25 for progressively storing positions of the portable telephone set 20 and also storing the received detailed map data, a display part 26 constituted by a liquid crystal display unit or the like for displaying road map and detailed map data, and an operating part 27 for accepting user's operations.
[0050]FIG. 6 shows an example of display to be carried by a walking person. When displaying the map during high speed movement such as movement on vehicle, the scale of the road map and the contents of detailed map data can be changed according to circumstances. FIG. 7 shows a road map which is displayed during high speed movement, FIG. 8 shows a detailed map shown during the high speed movement, and FIG. 9 shows a map displayed during the high speed movement. As shown in FIGS. 8 and 9, in this example parking places and gasoline stands (labeled GS) are shown in superimposition on the road map. Also, the map scale is reduced to match the moving range capable of being covered.
