<P>PROBLEM TO BE SOLVED: To control a timing for storing input data in second storing means instead of first storing means depending on importance of the data when the operation condition of the first storing means is abnormal. <P>SOLUTION: When determining that the operation condition of a storage part is abnormal, the CPU decides an alternative period that is a period of a process for storing the input data in an alternative storing region of a RAM based on a process frequency in process history of the self apparatus, and sets an alternative permission period for permitting a process for storing the data with importance equal to or higher than importance in the decided alternative period for each importance specified to the data, in the alternative storing region. In addition, after the CPU determines that the operation condition of the storage part is abnormal, when new data is inputted and the data input timing is within the alternative permission period corresponding to the importance of the data, the input data is stored in the alternative storing region of the RAM. <P>COPYRIGHT: (C)2011,JPO&INPIT |
