Abstract

PURPOSE:To understand the contents stored in a memory card, and also, to know its area, and to efficiently use the memory card, by providing a program data discriminating part and a data area designating part on the memory card. CONSTITUTION:When a power source is turned on to a CPU 2, a program in an internal storage device 8 is started, and a program data discriminating part 3 in a memory card 1 is retrieved. Subsequently, whether the contents of the card 1 are a data or a program is checked, and in case of the data, the program in the device 8 is executed continuously. On the other hand, in case when the contents of the card 1 are the program, a data area designating part 5 is retrieved. In such a way, whether a data area exists in the card 1 or not is checked, and when the data area exists, its part is used as a data area. Subsequently, a program area designating part 4 is retrieved, and the program in the card 1 is executed. Accordingly, even if a user has no concern in the contents of the card 1, the use corresponding to the contents can be executed, and the card 1 can be used efficiently.
