<p>PURPOSE:To facilitate the operation of a power source control for plural respective controlled device when a control is not received from a high order device by providing a power source control means to send a power source control signal to respective controlled device. CONSTITUTION:When the power source on instruction of a device is executed from a control device 1 of a high order device through power source control interfaces 51-53, the power source of devices to be controlled 2-4 of a low order device is successively turned on. The power source control means to provide respective controlled devices 2-4, when a self-device is made into the local condition not to receive the control from the high order device, sends a power source control signal to control the on or off condition of the device power source from the self device to the power source control interface of the device to be controlled of other low order device. Thus, the operation of the power source control for the device to be controlled of plural respective low order devices in a system when the control is not received from the high order device is facilitated.</p> |
