Claims (1)

[Claims for Utility Model Registration] A current position setting section 2 for setting the current position of a moving body by displaying a cursor on map data indicating coordinates specified in advance by a coordinate input means 1; a current position updating unit 3 that automatically updates the set current position based on the moving distance data and azimuth data of the moving body detected by the moving distance sensor 6 and the azimuth sensor 7, respectively;
and mode selection means 4 for selecting either the current position setting mode or the current position update mode, wherein the mode selection means 4 selects the current position setting mode. A location device characterized by comprising an azimuth data display control unit 5 for sometimes displaying azimuth data at the time of setting the current position of the moving object on the map data on which the cursor is displayed.
