PURPOSE:To prevent operation excepting for a sales region by comparing sales area information in a storage unit which is freely attachable and detachable to a main body unit and sales area information in the storage means of the main body unit by the execution of a basic program so as to judge the possibility of the execution of an application program. CONSTITUTION:CPU 10 reads out and compares an area discrimination code in an area discrimination code storage memory 12 and an area corresponding code in a program memory 14. When they are coincident, the checking of an area code is started. CPU 10 reads out and compares a cipher code for area discrimination in the area discrimination code storage memory 12 and the area code in the program memory 14. When they are coincident, CPU 10 starts the execution of a game program in the program memory 4 but when they are not coincident, CPU 10 executes a program excepting for the game program. For example, the impossibility of the usage of this program is displayed. |
