<p>PURPOSE:To easily grasp the movement path of a golf cart on a golf course by displaying an image on a display unit while the movement track of the golf card is superimposed on the map of the golf course in specific pattern. CONSTITUTION:A CPU 7 calculates the travel azimuth of the card from the output of an azimuth sensor 1 at a specific period by timer interruption, and also finds longitude and latitude data indicating the current position coordinates of its own golf cart from a travel distance and the travel azimuth or the output of a GPS(Global Positioning System) device 4 by interruption at intervals of a constant distance travel based on the output data of a distance sensor 3 and stores them as current place data in a RAM 9. The map data on a hole area including the current position coordinates are read out of a CD-ROM and supplied to a display device 16. Consequently, the movement path of the golf card can be grasped, so respective holes are put in good condition according to the obtained movement path, so that the golf card can smoothly travel.</p> |
