Depositing apparatus for performing a depositing process on a storage medium with a radio communication function for use in an automatic toll adjusting system

摘要

A depositing apparatus made use for an automatic toll adjusting system for performing a depositing process for toll pre-payment on a storage medium (1) with a radio communication function, said storage medium (1) with the radio communication function being carried by each user for storing adjustment information necessary for toll adjustment therein and exchanging information with outside in radio communication in a first predetermined frequency, comprising:- a communicating means (7A) for directly exchanging information with said storage medium (1) with the radio communication function in radio communication at the first predetermined frequency;- a depositing means (7B) for performing the depositing process on said storage medium (1) with the radio communication function; and- a demand issuing means (7C) for issuing a read demand to read balance information or a write demand to write depositing information and new balance information resulted from the depositing process by said depositing means (7B) to said storage medium (1) with the radio communication function via said communicating means (7A);whereby- when said depositing apparatus performs the depositing process on said storage medium (1) with the radio communication function, said demand issuing means (7C) issuing a read demand to read said balance information to said storage medium (1) with the radio communication function through said communicating means (7A);- when said depositing apparatus receives the balance information from said storage medium (1) with the radio communication function through said communicating means (7A) in response to said read demand, said depositing means (7B) adding a sum of money deposited this time to said received balance information to obtain a new balance;- said demand issuing means (7C) issuing a write demand to write the balance information including the new balance calculated by said depositing means (7B) and the depositing information including the sum of money deposited this time to said storage medium (1) with the radio communication function through said communicating means (7A).
