PROBLEM TO BE SOLVED: To execute equal functions by both contact and contactless systems by discriminating by which it is started between contact and contactless interfaces and making a card switch to an executable command. SOLUTION: A CPU 405 confirms the states of input terminals A and B at the time of initialization, discriminates by which a radio combination card is driven between contactless and contact interfaces 400 and 401 and stores the result in a RAM 409. On the other hand, a command table which associates a command from the outside with a subroutine program of a ROM 406 is distinguished between contact and contactless systems and is stored in an EEPROM 407. Also, the ROM 406 stores a subroutine program for command processing and the CPU 405 refers to the RAM 409 and the EEPROM 407, reads the subroutine program and executes it according to a command from the outside. Thus, the functions of both drive systems are equally maintained by switching an execution command. |
