Abstract
The present invention is directed to an information terminal device. A memory card 14 stores a serial number MID of the memory card 14 and a MID register program for registering the serial number MID in the information terminal device 10. At starting the information terminal device 10, the MID register program is downloaded from the installed memory card 14 and the serial number MID stored in the memory card 14 is stored in a non-volatile flash ROM 30 in accordance with the program. Then, the MID register program is cleared out of the memory card 14 and the MID register program on a SDRAM 32 downloaded to the information terminal device 10 is made invalid. Such processing prevents the serial number of the memory card 14 from being thereafter stored in the other information terminal device 10.

24. A predetermined information changing program which is a computer readable program for causing an information terminal device in which a storage medium is detachably installed to execute operations comprising:
-
a first operation of determining whether identification information for identifying the storage medium, which has already been stored in a first internal memory of the information terminal device, corresponds to the identification information of the storage medium now installed in the information terminal device; and
a second operation of replacing predetermined information, which is different from the identification information, stored in the second internal memory with predetermined information on the storage medium now installed in the information terminal device if both identification information is determined to corresponds each other in the first operation.

25. A terminal operating program which is a computer readable program for causing an information terminal device in which a storage medium is detachably installed to execute operations comprising:
-
a first operation of determining whether identification information for identifying the storage medium is stored in a first internal memory;
a second operation of storing predetermined information on the storage medium, which is now installed in the information terminal device, in a second internal memory of the information terminal device under a predetermined condition when it is determined in the first operation that the identification information is not stored in the first internal memory; and
a third operation of causing the information terminal device to operate according to the predetermined information stored in the second internal memory by way of the second operation. - View Dependent Claims (26)
