ABSTRACT:
A disc loading structure capable of safely and effectively carrying out a disc loading operation free from mistake. The disc loading structure includes a sensor group consisting of a plurality of disc detecting sensors each selectively exhibiting a detection mode and non-detection mode. The sensor group is arranged so as to permit the disc loading structure to properly accomplish the disc loading operation such as detection and ejection of any foreign article inserted therein, discrimination and loading of each of discs different in size and the like, depending upon a pattern of combination of the detection and/or non-detection modes of the sensors.
