Abstract

PURPOSE: To save sharply the waste of power at the time when a system is not used by sending the output of a sequential or individual supply cut off controlling part and a memory controlling part to an output controlling part and operating ON/OFF of power source of each device.
CONSTITUTION: Command receiving part 11 receives an instruction from CPU through I/O bus and command controlling part 12 controls the power source of devices by receiving the output from the command receiving part and address receiving part 10 which receives device addresses through I/O bus. Where, sequential supply cut off controlling part 13 cuts off sequential power supply by means of the output of controlling part 12 and individual supply cut off controlling part 14 cuts off power supply individually by menas of the output of controlling part 12. The output of controlling parts 13 and 14 and control memory circuit 16 is sent to output controlling part 18 and ON/OFF operation of power source of each device is executed. Thus, the waste of power at the time when the system is not used can be saved sharply by controlling each device in sequence or individually by means of a program.
