<p>PURPOSE:To connect the same display devices to a system device to which plural display devices can be connected by adding to a remote operation circuit such as a relay to the power circuit of the display device. CONSTITUTION:For the power-on system of a system device 1 and a display device 8A, a system power source control part 13 turns ON a power source 7 and informs a processor part 3 that the power source of the system is turned ON when the power switch 11A of the display device 8A is turned ON. Then the processor part 3 powers ON a keyboard 9A and a mouse 10A. When its electric power passes through the display device 8A, a power lamp 12A illuminates and a relay 15A turns ON to turn ON a display power source 16A. Similarly, when the power switch 11B of a display device 8B is turned ON, a relay 14B is excited to turn ON a display power source 15B.</p> |
