Abstract

PURPOSE: To ensure protection for not only the circuit elements and the like but the data under being processed by delivering with delay of a fixed time the detection output of reduction and stoppage for the action of the fan which cools down the information processor and then cutting off the power source.
CONSTITUTION: The reduction or stoppage of the action of cooling fan 10 is detected by detector 20. Output (a) of detector 20 changes from the lower to higher level, and this change is informed to information processor 100 via signal line 300. And the data which is under process then is protected through such process A that memorizes the data into the nonvolatile memory and other processes. Power unit 30 is cut off immediately when it receives supply of the output of detector 20 with delay of fixed time T. After repair of fan 10, the power source is thrown in to restart the discontinuation of processor 100.
