PURPOSE:To make it possible to reduce the consumption of electric power as well as its noise, and further, smoothly reopen the copying by maintaining the energization to the DC control circuit after the end of copying, and interruptng the energization to the AC load. CONSTITUTION:AC load, such as preheating and energizing the starter St for fan motors FM1, FM2 and exposure lamp 16. DC control circuit which controls the copier by rectifying AC voltage with rectifier REC so as to give it to central processing circuit CPU. The invention is provided with the above, AC lead and DC control circuit. After the end of copying, the energization to the starter ST, heater 46, and fans FM1, FM2 is interrupted by exciting relay F with the signal SOFF from the central processing circuit CPU so as to change contacts K1-k4, but DC electric power maintains its energization state, hence the process can be reopened by making the copy button ON only. |
