To enable use of a low-speed online circuit which is already in operatation, when online revision is carried out in various station service apparatuses in each station, by means of a host computer 10 and reduce a data amount flowing through the circuit for reducing the traffic amount of the circuit.

When the host computer 10 is connected to automatic fare adjusting machines 3, etc., automatic ticket issuing machines 4, etc., automatic ticket gate machines 5, etc., online, fare-to-kilometer information, station interval information, and cross station information as common basic data to be fed is transmitted to one automatic fare adjusting machine 3 in each station; and by mean of this automatic fare adjusting machine 3, station-to-station fare data common between the respective station service apparatuses are formed. When the formed common station-to-station fare data are transmitted, another station service apparatus extracts (forms) fare data for its own apparatus from the common station-to-station fare data.
