<p>PURPOSE:To provide an information processor which can detect and display an instantaneous power failure without increasing its size and cost and also can improve its operating facility. CONSTITUTION:This information processor is provided with a CPU 6 which has an interruption processing function to read and control the program stored in a memory 10, a display part 7, a nonvolatile storage medium 9, and a power failure detecting circuit 20. When an instantaneous power failure detected by the circuit 20 the fact, is the medium 9 and also shown at the part 7 by executing the interruption processing of the CPU 6. When a power supply is turned off before the display is performed at the part 7, the information showing the instantaneous power failure is read out of the medium 9 and displayed the part 7 when the power supply is turned ON again.</p> |
