PURPOSE:To automatically control the operation of a system when a temperature is abnormal by stopping the supply of power when the temperature inside a case body becomes equal to or more than a first prescribed temperature, saving restart information before stoppage and restarting the operation of the system by the restart information saved inside a memory unit when the temperature becomes equal to or less than a second prescribed temperature. CONSTITUTION:A temperature abnormality detection part 1 detects that the temperature inside a device is higher than a prescribed temperature and performs output to a system operation control part 2. Then, an instruction signal is sent out to a central processing unit (CPU) 3 and the restart information such as an execution state for indicating the operating state of the CPU 3 or the like is saved at the specified address of a main memory unit 4. The system operation control part 2 confirms whether or not a saving operation is completed, stops the CPU 3 through a CPU control line 11 and stops power supply. Then, when temperature abnormality is recovered, the CPU 3 reads the restart information saved in the main memory unit 4 from the main memory unit 4 through a system bus 10 and executes the restarting of the operation by the restart information. |
