Abstract: A disc holder having a rigid central core for projecting through the central aperture of an optical disc in order to hold the optical disc in place. The disc holder includes, in addition to the rigid central core, a base, several support arms that extend radially inwardly from the base to support the central core in spaced relation from the base, and securing means for releasably securing the rigid central core within the central aperture of the optical disc. The securing means includes locking fingers mounted on the central core. The locking fingers are biased outwardly against the edge of the central aperture of the disc when the disc is held by the disc holder. The locking fingers are moveable radially inward to fit within the central aperture of the disc, thereby allowing the disc to move over the locking fingers so that the disc can be put on or taken off the disc holder.

Abstract translation: 具有用于通过光盘的中心孔突出以用于将光盘保持在适当位置的刚性中心芯的光盘保持器。 除了刚性中心芯之外，盘保持器还包括基部，几个支撑臂，其从基部径向向内延伸以支撑与基座间隔开的中心芯，以及固定装置，用于将刚性中心芯可释放地固定在内 光盘的中心孔径。 固定装置包括安装在中心芯上的锁定指状物。 当盘由盘保持器保持时，锁定指状物被向外偏压抵靠盘的中心孔的边缘。 锁定指状物可径向向内移动以装配在盘的中心孔内，从而允许盘在锁定指状物上移动，使得盘可以被放在或从光盘托架上取下。
