ABSTRACT:
A multiplex image forming apparatus remains in a standby state for multiple functions including a copier function, a facsimile function and a printer function at all times and, in a receive mode at night, fully deactivates devices to be not used, thereby saving power and reducing noise. The apparatus has a power source for a copier, and an application extending section capable of combining a facsimile function with the apparatus and a power source for a multiplex configuration for driving the application extending section. A first and a second power source switch is located at an input section preceding the two power sources. A detecting circuit is connected to the first power source switch to detect the turn-on and turn-off of the switch. Detection signal output control means transfers a detection signal from the detecting circuit to a control circuit only when the second power source switch is turned on and the first power source switch is turned off.
