Abstract

PURPOSE:To limit to appropriate an external storage medium in which a system software has been written, for other device, by inhibiting the loading, when the number of times of loading of the system software has exceeded a set value. CONSTITUTION:To a loading frequency set value memory 30, the number of times for permitting the loading of a system software is determined and set in advance, and its numerical value is stored. Also, as for a display part 31, on the other hand, an area for writing a data for showing the number of times of loading which has been executed already, of the system software is determined to a floppy disk. Whenever loading of the system software is executed, the number of times of loading which has been executed already, written in the floppy disk is counted up and rewritten, and when this number of times of loading which has been executed already has exceeded the allowable number of times, loading is inhibited. In such a way, it is limited to appropriate the system software for other device.
