Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a navigation system of a simple constitution which does not use a GPS-receiving device. SOLUTION: Map data, on a predetermined service area, are stored in a map data storage part 46. Bar codes are pasted on columns and walls of buildings in the service area, and the bar codes indicate their locations. A bar code processing part 41 analyzes the bar codes read by a bar code reader provided for a portable terminal 20. A present location detecting part 42 detects the present location from the results of the analysis. After a destination selection processing part 43 presents a menu to have a destination selected, a route selection processing part 44 specifies a route from the present location to the destination through the use of the map data.
