<p>PROBLEM TO BE SOLVED: To execute shut-down while data is guaranteed even in the case of an inconvenient operation except for a power cut. SOLUTION: A cooling fan fault detection means 60 and an intra-case temperature detection means 70 are provided. A power control circuit 40 is formed so that it can output a trigger signal CST (shut down request signal) even if a fan fault detection signal Sf and a temperature high detection signal St are inputted apart from a power cut signal Ss. Effect that a physical event except for software can be detected and effect on the generation of the detected physical event can directly or indirectly be transferred to a control part 20 through a serial line 22C as a part of the shut down request signal.</p> |
