PURPOSE:To provide an information processor which can securely prevent the disappearance of data in the middle of a processing with a traveling application program owing to power interruption by power failure or misoperation. CONSTITUTION:A backup memory area 14 consisting of the non-volatile memory element of EEPROM and the like is provided as the storage area of data to be inputted/edited so that the storage content is always held. At the time of inputting/editing data, a processing is executed for an input/editing data file on the backup memory area 14, and the data file is saved to an external storage device 3 at the time of need. A flag showing whether data is saved to the external storage device 3 or not is added to the file in the backup memory area 14. When the file where data is not saved in the external storage device 3 at the time of starting a device exists, a prescribed restoration processing is executed. |
