Abstract
A first detector is provided for detecting an optical disc inserted in an opening of a reproducing system and for producing a first signal, and a second detector is provided on a reproducing device for detecting the disc carried to the device and for producing a second signal. A sensing circuit is provided for sensing a temporary reduction of a voltage of power supplied to the system and for producing a temporary reduction signal. A control means is provided to be responsive to the first signal and to the temporary reduction signal for operating a carrying device to carry the disc in an unloading direction, and in a loading direction when the disc reaches a predetermined position.
