Abstract

PURPOSE:To prevent malfunction owing to electric power source surging at the power ON and prevent malfunction owing to active operation at the resetting of an LSI chip by providing a means of turning OFF the DC power system during continuation of system reset pulse and a means of turning ON the AC power system after DC power system ON. CONSTITUTION:This is the interface control system relating to the setting order of the power system loads at the electric power source ON in particular in the copying machine control system using a microcomputer, wherein a microcomputer 1, ROM2, RAM3, system reset circuit 14, etc. are provided and power relays 19, 20 are OFF while reset pulses are being put in them. When there are no more reset pulses, the power relay 19 goes ON to supply DC source. Next, when the CPU1 starts and the power relay 20 is turned ON by the program, the AC source is supplied.
