Abstract

PURPOSE:To eliminate the need of a sub-power source or a power source controller, by executing a power source control of a processor from the side of plural sets of display devices. CONSTITUTION:When a processor 1 and all display devices are disconnected from a power source, when a power source of a display device 2A is turned on, a +5V output 8 of a power source 7 is transmitted to an OR circuit 3, a signal 9 goes to +5V through a diode 5 and a power source 4 is turned on. When the power source of each display device is disconnected, and all the display devices are brought to power source disconnection, the signal to the OR circuit 3 all goes to '0'V, and the signal 9 which has passed through the diode 5 also becomes '0'V, and the power source 4 is brought to power source disconnection. In such a way, the power source of the processor can be controlled from the display device side.
