Abstract

PURPOSE:To prevent a malfunction of a device, by delaying the supply of electricity to the power source of the device which is controlled by a microprocessor from the supply of electricity to the power source of the microprocessor. CONSTITUTION:When a power supply application switch SW2 is turned on, the current given from an AC power supply 1 flows to the coil of a relay RL4 to actuate the relay RL4. Then a relay RL2 works to start the supply of electricity to the power source 3 of a microprocessor CPU5. Thus the CPU5 starts its operation to produce an output through an output port 8 when a certain period of time elapses. Then a relay RL7 works by the output of the port 8, and then a relay RL1 works to start the supply of electricity to a device power source 4 such as a motor 6, a solenoid 7, etc. In such way, the supply of electricity to the power source 4 is delayed from the power source 3 by a specified delay of time, thus the malfunction of a device is prevented.
