PURPOSE:To easily and accurately restore characteristic data which are lost by allowing data to be written in a 1st memory space only when specific input operation is performed. CONSTITUTION:It is decided whether or not the specific input operation for a password, etc., is performed to allows a 1st memory space to be referred to and inhibits the 1st memory space from being written when a machine is actually operated without inputting a password, and allows the 1st memory space to be written when the password is inputted. Then when it is decided that data for adjustment written in a 2nd memory space are abnormal and the number of the abnormal data is less than a specific value, the data in the 1st memory space 11 corresponding to the abnormal data are referred to and the data are overwritten on the abnormal data in the 2nd memory space 12. When the number of the abnormal data is larger than the specific value, on the other hand, all the data in the 1st memory space 11 are referred to and overwritten while made to correspond to all the data in the 2nd memory space 12. |
