Abstract

PURPOSE:To easily set a personal computer, etc., into a system by interruption temporarily the power supply of an equipment to be initialized when no signal is received any more, and initializing said equipment after energizing it. CONSTITUTION:When the normal processing is carried out any more, no watchdog timer signal W is produced. Thus the output of the signal W is stopped. Under such conditions, a normalcy/abnormality deciding part 4 detects the stop of the output of the signal W and produces a temporary OFF signal C. Thus the power supply MP outputted from a power supply open/close part 5 is temporarily interrupted. As a result, the reset circuit of a personal computer 1 works and each circuit part of the computer 1 is initialized. Thus the runaway of the computer 1 if occurs is detected and the MP is temporarily interrupted and initialized. Then a normal personal computer, etc., can be automatically initialized and then easily set into a system.
