PURPOSE:To realize a continuation processing from a state before a power failure at the time of power restoration by saving data of a memory in an external storage device when a power failure notice signal is inputted and loading data in the memory when feeding resumes. CONSTITUTION:When the power failure is detected, the power failure notice signal is transmitted from a control circuit to an ECR 1 through a signal line, a signal terminal and a signal line 5. In the ECR 1, state information of CPU 11 which is executed at present is once saved in RAM 13, and the whole content of RAM 13 is saved in HDD 21. Then, the stop command signal of an inverter circuit is transmitted from the ECR 1 to UPC 3 through a signal line 4. When power is restored, data which is saved in HDD 21 at the time of the power failure is loaded on RAM 13 in the ECR 1, and the address and the register of CPU 11 are restored to the state before the power failure. Thus, the processing is continued from the state before the power failure in the ECR 1. |
