PROBLEM TO BE SOLVED: To improve the reliability of data with simple arrangement as to a data count processing apparatus. SOLUTION: A correcting process part 24 corrects a count value according to the comparison result of a comparing circuit part 23 which compares a count part 21 stored with the current count value and a backup part 22 stored with the last count value. The correcting process part 24 makes no correction when the values of the count pat 21 and backup part 22 are equal to each other, or copies the value of the backup part 22 to the count part 21 when the value of the backup part 22 is larger than that of the count part 21, the value of the backup part 22 to the count part 21 when the value of the count part 21 is larger than the value obtained by adding a unit quantity to the value of the backup part 22, or the value of the count part 21 to the backup part 22 when the value of the count part 21 is the unit quantity larger than the value of the backup part 22. |
