PURPOSE:To safely and exactly operate an interruption processing even when a power source trouble occurs at the time of the absence of a person. CONSTITUTION:A power supply is operated from a battery 11a to a computer device 2 at the time of the occurrence of the power source trouble, also whether or not back-up currents are supplied from the battery 11a is detected by a back-up state detecting part 11c. When a current supply time measured by a timer managing part 21c passes a prescribed time set within the supply limit time of the battery 11a, an end processing part 21d ends the executing processing of an application processing pat 23. And also, when the output potential of the battery 11a is detected by a potential detecting part 11d, and the output potential is lower than a prescribed potential set higher than the operation validating potential of the computer device 2, the processing of the application processing part 23 is ended. |
