Abstract:
A disk holder which comprises a first core and a second core, which is inserted into an axle hole of a disk, and which supports a plurality of disks at intervals in a row, whereineach of said cores has a given length with a generally U-shaped cross section and is combined to oppose each other so that adjustment of expansion and contraction of the cores can be carried out between an expanded diameter position where an inner periphery of the axle hole of the disk is supported by parts of a circumference surface of the holder, and a contracted diameter position where the holder is inserted into and withdrawn from the axle hole of the disk, each of the cores has rows of guides and supports on an outer surface thereof so that the rows of the guides form flutes for supporting the disks at predetermined intervals by receiving the disks one by one inbetween the guides, and the supports are projected rows for supporting the inner periphery of the axle hole of each of the disks as multi-point support, said first core having two rows of the supports and said second core having one row of supports.
