PURPOSE:To reset a control system consisting of multi CPU or the like surely and in a short period of time. CONSTITUTION:When a power supply output from power supply 1 for an on/off controllable driving system is turned off by the main CPU 11, the power supply output is forcibly discharged by a lamp 12 and transistor 13, and by a diode 25 the reverse flow of current to the power supply 1 from a load system is protected. Further, when the main CPU 11 detects the drop of the power output by power off is detected by inputting a signal from analog input port AN, the power supply 1 is turned on again, thereby activating reset circuits 16, 17, and 18 of sub CPU 15 to rest the sub CPU 15. |
