<p>PURPOSE:To exchange storage units even if the power source of a processor is not disconnected by copying the stored content of the storage unit whose receive life does not last long into an exchange unit when it is inserted, and switching the storage unit after copy completes. CONSTITUTION:In addition to spaces 13-13n storing the storage units 14a-14n, a space only for exchange 15 storing the exchange unit 16 are provided. Function DPF displaying the storage unit to be exchanged, function IRF identifying that the new storage unit is inserted into the space only for exchange and copy function CPF copying data from the storage unit to be exchanged to the new storage unit are provided to an information processing part 11. when the exchange unit 16 is inserted into the space only for exchange 15, the stored content of the storage unit 14a whose service life does not last long is copied in the exchange unit 16 and it is switched to the storage unit 16. Thus, the storage units can be exchanged even if the power source of the processor is not disconnected.</p> |
