Abstract

PURPOSE:To prevent illegal use without deteriorating the portability of a user by including time calibration data into the data outputted from a medium processor to a storage medium. CONSTITUTION:CPU 11 reads present time from a clock 15 and stores it in the prescribed memory area of RAM 13 as wicket entering time at the wicket entering time when the user enters into a station from a wicket. At the time of leaving the wicket, CPU 11 similarly reads present time from the clock 15. When a difference between present time and ticket barrier entering time is within permissible time, medium data is read from EEPROM 14 and it is transmitted to the medium processor. Then, CPU 11 stands by for the transmission of a time calibration command from the medium processor within prescribed time. When the time calibration command is received from the medium processor, CPU 11 calibrates present time which is set in the clock 15 and transmits a calibration termination response.
