PURPOSE:To provide the information processor which is improved in the reliability of a resuming function and superior in practicability. CONSTITUTION:A main device is equipped with a CPU (saving means) 10, a semiconductor memory 11, a nonvolatile storage medium 12, a battery part (battery) 20, a battery state detecting circuit 21, a power circuit 22, a power switch 23. and a power source control circuit 24. When the power source is turned off by operating the power switch 23, the CPU 10 saves information on the process state at the time of the power-off operation in the semiconductor memory 11. The battery state detecting circuit 21 detects the output voltage value of the battery part 20 which drives the semiconductor memory 11 and when the detected value decreases below a specific value, the CPU 10 transfers the contents saved in the semiconductor memory 11 to the nonvolatile storage medium 12. |
