Abstract: A retaining structure with double-face carrier function includes a carrier unit, an elastic unit and a retaining unit. The carrier unit has a carrier body and a through hole passing through the carrier body. The elastic unit has a plurality of elastic arms extended from an inner surface of the through hole. The retaining unit has a plurality of retaining elements passing through the through hole. Each retaining element has a retaining portion connected to at least two of the elastic arms and extended above and under the through hole, a pressing portion extended inwards from one end of the retaining portion and at least one protrusion portion disposed on an outer surface of the retaining portion and adjacent to the pressing portion. The pressing portions above the through hole are arranged alternately and the pressing portions under the through hole are arranged alternately.

Abstract: A multiple optical disc storage case includes a upper cover, a lower supporting plate, an outer fastener, and a plurality of inner hooks. The upper cover is hollow, and the lower supporting plate is used to assemble with the upper cover. The outer fastener is positioned at one of the upper cover and a lower supporting plate, and has at least one outer hook, at least one stop block and a plurality of resilient block. The outer hooks and the stop blocks are positioned at one side of the outer fastener, and the resilient blocks are equally separated and positioned at the other side of the outer fastener. The outer fastener also has a plurality of inner hooks positioned at the other of the upper case and the lower supporting plate so that the inner hooks are hooked up with the outer hooks.

Abstract: A disc box structure according to the present invention includes a shell and an auxiliary support. The shell has a base, and a stand protruding upwardly from the base for accommodating a disc. The auxiliary support includes a pivot connected to the base, a lateral arm arranged to a side of the pivot, a pressing portion disposed over the lateral arm, and a stand connected to an opposite side of the pivot. Therefore, the pressing portion is pressed down to release the disc in order to lift the auxiliary support upwards, so that the disc is raised for easy removal.
