PROBLEM TO BE SOLVED: To easily restore system information.SOLUTION: In an automatic transaction device 1, a first storage unit 2 stores first information 2a that is created each time transaction processing is executed, and a second storage unit 3 that is a flash-type semiconductor memory stores second information 3a having a lower rewrite frequency than the first information 2a. This suppresses both the rewrite frequency to the second storage unit 3 and the replacement frequency of the second storage unit 3, thereby suppressing an increase in cost. In addition, in the automatic transaction device 1, a transfer unit 6 transfers a copy of the second information 3a of the second storage unit 3 to the first storage unit 2. Thus, a restoration unit 7 can easily restore the second information 3b (the second information 3a) in the second storage unit 3 by relocating the second information 3b from the first storage unit 2 to a new second storage unit 3 that is obtained by replacement. |
