A disk storage box comprised of two pivoted shells connected by two axle caps with a hollow shaft retained therebetween to hold a plurality of flat disk holders. Lifting one shell from the other causes said axle caps to rotate said hollow shaft, permitting said flat disk holders to be spread out like a fan for arranging laser disks or floppy disks conveniently. Stop strips are made in connecting rings on one shell to confine said axle caps to be rotated within a fixed angle.
