Abstract
An electric apparatus for carrying out start-up control of a plurality of devices requiring start-up electric currents exceeding an amount of current required at ordinary states thereof. The apparatus has a power source, a signal generating circuit for generating a stable state signal when one or the plurality of the devices enter a stable state after start-up thereof and a control circuit for causing a next device to start in response to the output of the stable state signal to the previously started device or devices. One example of the signal generating circuit includes an electric current measuring circuit and judges that the device is at a stable state thereof when the electric current supplied to the device becomes lower than a predetermined value. The above construction temporarily prevents maximum start-up currents of the devices from being supplied from the power source to the respective devices and consequently reduces the electric load on the power source.
