Abstract
A door opening and closing mechanism, wherein a swinging door to cover an opening for loading, unloading, or exchanging discs comprises two doors, an upper door (14) and a lower door (13), each of which is supported by pivots (14a) and (13a). The opening is covered, when closing the doors, with the two doors, the upper door (14) and the lower door (13), by an interlocking motion by engaging a sliding guide (14b) provided on the upper door (14) and a sliding pin (13b) provided on the lower door (13). When opening the doors, the lower door (13) is nested inside the upper door (14) guided by pivots (14a), (13a), the sliding guide (14b), and the sliding pin (13b), whereby the amount of the projection of the doors when open corresponds to the projection only of the upper door (14).
