发明名称 AUTOMATIC RECEIPT SYSTEM OF PARKING FEE
摘要 <p><P>PROBLEM TO BE SOLVED: To provide an automatic receipt system of parking fee to preliminarily let a user know how many hours the user is able to park from the prepaid balance of a current IC card when a vehicle passes the entrance gate of a parking lot. <P>SOLUTION: An onboard device 10 reads the balance of an inserted IC card 20, and transmits the data to a roadside device 1. The roadside device 1 calculates a parking enabling time corresponding to the prepaid balance, and transmits it to the onboard device 10. The onboard device 10 outputs the parking enabling time from a display part 15 and a loudspeaker 17. The onboard device 10 monitors an elapsed time by time data from a time measuring part 18, and when it exceeds the parking enabling time in user's leaving, the on-vehicle device 10 notifies its exceeding and insufficient charge to the user. After the lapse of the parking enabling time, the roadside device may let the user know the lapse of the time by a portable telephone. In the system to pay a parking fee at a parking lot by using an IC card stored with a prepaid balance, it is possible to solve the problem that the prepaid balance is unknown until the user inserts the IC card into a fare adjustment, and that it is necessary for the user to perform fare adjustment again when the prepaid balance is insufficient. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p>
