There are circuits to reduce consuming power of an electric and electronic equipment; a circuit to control clocks(4) for each device by a CPU, and to be variable by dividing clock, a circuit to access from the synchronous CPU to an asynchronous memory(5) in high speed, a standby circuit connecting a relay(2) to an AC to DC converter(1) without any transformers and a communication circuit(3) connecting to an external apparatus with photo couplers. By the above, these exclude futile power with high speed clock and loss of a transformer circuit.
