Embodiment Construction

[0041] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0042] figure 1 A configuration diagram showing a system of an embodiment of the present invention. The system of this embodiment includes: an information terminal device 10 mounted on a vehicle; a center 12 for managing information distributed to the information terminal device 10; and using the information terminal device 10 to provide, for example, distribution map data to passengers. , A system for distributing services such as music performances.

[0043] The information terminal device 10 has a memory card slot (not shown) into which a memory card 14 such as an SD (Secure Digital) card can be inserted, for example. The memory card 14 is detachably mounted in the memory card slot. The memory card 14 has a predetermined storage capacity as a storage medium, and can write various programs such as application programs required for operating the informatio...

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.

Description

technical field [0001] The present invention relates to an information terminal device, an operation control method of an information terminal device, a specific information storage program, a storage medium storing a specific information storage program, a predetermined information change program, a terminal operation program, a storage medium and a center for storing a terminal operation program, and particularly to An optimal information terminal device or the like in which information such as a program held by the information terminal device is updated by distribution via a rewritable storage medium. Background technique [0002] Conventionally, for example, Japanese Patent Application Laid-Open No. 2002-139326 discloses an information terminal device that takes out a program stored in the storage medium from a storage medium such as a detachably mounted CD-ROM, and makes the The program is stored in the internal memory, and the program in the internal memory is started....
