PROBLEM TO BE SOLVED: To provide a relatively low-cost road guidance device dispensing with a multitude of sensors, arithmetic units, etc., and accordingly, dispensing with the large-scaled installations. SOLUTION: While a portable terminal 2 is not operated, a guidance display device 4 performs display only by a guide display part 41 for walkers and vehicles. When a walker 1 inputs a destination into the portable terminal 2 to transmit a destination radio signal, the display device 4 receives a signal of its own address to actuate an attention attracting display part 42. A user recognizes the existence of a guide display part and its displayed description by the actuation of the attracting display part. COPYRIGHT: (C)2005,JPO&NCIPI |
