recording or playback apparatus using mechanically marked tape, e.g. punched paper tape, or using unit records, e.g. punched or magnetically marked cards G06K; transferring data from one type of record carrier to another G06K1/18; circuits for coupling output of reproducer to radio receiver H04B1/20; gramophone pick-ups or like acoustic electromechanical transducers or circuits therefor H04R) ## Abstract A compact disc storage box for receiving a compact disc consisting of a flat housing having bottom and cover plates, wherein a disc carrier is drawer-like supported so as to be slidable between inserted and outer end positions, has means for urging the disc carrier toward either of its end positions including a spring clip mounted pivotally on the bottom plate and engaging the disc carrier for urging it toward and retaining it in its end positions. ## Claims ### Claim 1 A compact disc storage box for receiving a compact disc (CD) consisting of a housing having a bottom plate and a cover plate with side walls joined together such that said bottom plate and said cover plate are disposed in spaced parallel relationship to each other and define therebetween a space with a front opening, a disc carrier supported in said housing so as to be slidable into, and out of, said housing through said front opening between an inner end position in which said disc carrier is fully inserted in said housing and an outer end position in which said disc carrier is slid at least partially out of said housing, means for releasably retaining said disc carrier in its inner end position, said retaining means including a spring clip mounted pivotally on said bottom plate and extending transverse to the direction of sliding movement of said disc carrier into, and out of, said housing, said spring clip engaging said disc carrier, an ejector slide slidably supported in said compact disc storage box adjacent to, and at one side of, said disc carrier so as to be slidable in the same direction as said disc carrier and a double arm lever pivotally supported on a lug integrally formed with the bottom plate and having first and second ends, the first end hinged to said ejector slide and the second end hinged to said disc carrier. ### Claim 2 (depends on 1) A compact disc storage box according to claim 1 , wherein said spring clip is arcuately shaped and has opposite ends supported on said bottom plate. ### Claim 3 (depends on 2) A compact disc storage box according to claim 2, wherein said spring clip is a spring wire of circular cross section having outwardly bent ends supported on said bottom plate. ### Claim 4 (depends on 1) A compact disc storage according to claim 1, wherein said slide ejector is slidably supported on said bottom plate by an upwardly open guide structure defined at one side by a side wall and, at the other side, by a rib projecting upwardly from the bottom plate. ### Claim 5 (depends on 1) A compact disc storage box according to claim 1, wherein said ejector slide has downwardly projecting side, front, and rear walls defining a downwardly open cavity and a spring is disposed in said downwardly open cavity, said spring having an inner end and an outer end; wherein the outer end abutting the front wall of said ejector slide and wherein a stop member having first and second opposite sides is integral with said bottom plate and extending therefrom into said cavity, and wherein said inner end of said spring is abutting said first opposite side of said stop member and wherein said slide ejector has a slide ejector inner end with a tongue abutting the second opposite side of said stop member when said ejector slide is held by said spring in a forward rest position. ### Claim 6 (depends on 5) A compact disc storage box according to claim 5, wherein said tongue has an opening receiving a pin-like projection formed at said first end of said lever, said lever having at said other end an opening receiving a pin-like projection formed on said disc carrier. ### Claim 7 (depends on 2) A compact disc storage box according to claim 2, wherein said disc carrier has an underside and has a projection at its underside which is received in a guide slot formed in said bottom plate, said projection having a fork-like cavity receiving said spring clip. ### Claim 8 (depends on 1) A compact disc storage box according to claim 1, wherein said disc carrier has a rearward end at its rearward end an upwardly extending web structure formed along an arc having approximately in the radius of a compact disc wherein the web structure would prevent a CD placed on said disc carrier to slide off said disc carrier and side walls with fins extending parallel to the bottom plate and adapted to receive the edges of a CD disposed on said disc carrier for firmly engaging a CD in an area thereof which does not contain information and thereby prevent rattling of a CD. ### Claim 9 (depends on 8) A compact disc storage box according to claim 8, wherein said fins projecting from said side walls have projections so arranged that a CD inserted into said box all the way to the rear web structure would be engaged by said projections at the outer circumference thereof. ### Claim 10 (depends on 1) A compact disc storage box according to claim 1, wherein a sight slot is provided at the front end of said compact disc storage box. ### Claim 11 (depends on 1) A compact disc storage box according to claim 1, wherein a cut-out is provided in the front end of said box and said disc carrier has a projection which, when the disc carrier is in the outer end, position of said projection projects through said cut-out so as to permit detection whether said disc carrier is in its outer end or inner end position. ### Claim 12 (depends on 11) A compact disc storage box according to claim 11, wherein said cut-out and said projection are arranged immediately adjacent said ejector slide so that the presence of said disc carrier in its outer end position can be detected by touch of a finger. ### Claim 13 (depends on 1) A compact disc storage box according to claim 1, wherein said cover plate and bottom plate are each shaped having side edges, which, when assembled into the disc storage box, form grooves in the middle of the side walls of the compact disc storage box adapted to receive support webs of a compact disc storage box rack. ### Claim 14 (depends on 13) A compact disc storage box according to claim 13, each of wherein said cover plate and bottom plate has inclined side edges such that V-shaped grooves are formed between two disc boxes when joined together, said grooves being adapted to receive corresponding webs formed on the side walls of a disc box rack.
