Abstract

PURPOSE: To decrease the power consumption and to prolong the lifetime of each of distribution processing units by providing a loop control power supply part and a unit process power supply part on each title processing unit and adding a power supply control state in order to obtain a unit constitution accordant with the operating state and therefore driving/interrupting the unit process power supply part.
CONSTITUTION: A loop control part 1 of a distribution processing unit receives a command addressed to its own from a loop circuit 5, and a sequence control circuit 6 is operated to fetch a command to a command register 7. The contents of the register 7 are interpreted by a command detector 8. In the case of a unit inherent action, the output of the decoder 8 which instructs the working of a unit process part 4 with a control signal instructs the supply of power and the interruption of power to a unit process power supply part 3 with the power supply ON and OFF signals respectively.
