PROBLEM TO BE SOLVED: To improve reliability in data in a data transfer process. SOLUTION: The data processor has first, second, and third storage means. Data are stored to at least three storage locations (a), (b), and (c) of the first storage means. Storage is made to storage locations A, B, and C of the second storage means 6 corresponding to each of three storage locations. At least three data that are stored into the second storage means 6 are compared. According the comparison, classification is made. More specifically, a case (S6) where at least three data coincide one another, cases (S10 and S14) where two data coincide each other, and a case (S12) where entire data do not coincide one another are classified. Based on the classified state, storage to the third storage means 7 is permitted/prohibited to the data that are stored into the second storage means 6. COPYRIGHT: (C)2003,JPO
