Abstract
Abstract A disc record caddy comprises a pair of substantially flat circular covers releasably held in channels defined along the inside rim of an expandable circular ring. Spring elements bias the ring into a contracted shape to radially restrain a disc retained between the pair of covers. A platform, mounted on a base of a disc record player system, horizontally supports the caddy in an elevated position over a turntable of the system and includes means for expanding the ring to release the covers. A turntable spindle incorporates a lowering/lifting mechanism which lowers the cover nearest the turntable and the disc supported thereon onto the turntable for record playback purposes, the other cover being retained at the platform level by the radially inward extension of the land defined between the ring channels. At the termination of record playback, the disc and the supporting cover are lifted up to platform level and the ring is allowed to return to the contracted shape thereby enclosing the disc between the two covers. The expanding means and the lowering/lifting mechanism are actuated in response to the movement of a player lid.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
165 words
In a disc record player, including a turntable rotatably mounted on a base, for use with a record-enclosing caddy having a pair of substantially flat covers, with peripheries releasably held by an expandable ring in respective channels in the inner rim of said ring which are disposed on opposite sides of an inwardly-projecting central land of the ring; apparatus comprising the combination: means, mounted on said base and including a ring-engaging platform, for supporting a caddy in a position over said turntable whereat the covers thereof are substantially parallel to said turntable; first selectively actuated means for expanding the circumference of a platform-engaged caddy ring to an expanded shape permitting channel release of the lowermost of the covers held by said platform-engaged ring, while maintaining support of the uppermost of said covers on the central land of said ring; and second selectively actuated means, subject to engagement with the released cover, for lifting said released cover off said turntable and returning it to plaftform level.
Claim 2
Dependent Claim
165 words
In a disc record player, including a turntable rotatably mounted on a base, for use with a record-enclosing caddy having a pair of substantially flat covers, with peripheries releasably held by an expandable ring in respective channels in the inner rim of said ring which are disposed on opposite sides of an inwardly-projecting central land of the ring; apparatus comprising the combination: means, mounted on said base and including a ring-engaging platform, for supporting a caddy in a position over said turntable whereat the covers thereof are substantially parallel to said turntable; first selectively actuated means for expanding the circumference of a platform-engaged caddy ring to an expanded shape permitting channel release of the lowermost of the covers held by said platform-engaged ring, while maintaining support of the uppermost of said covers on the central land of said ring; and second selectively actuated means, subject to engagement with the released cover, for lifting said released cover off said turntable and returning it to plaftform level.
Claim 3
Dependent Claim
45 words
Apparatus as defined in claim 1 also including a lid subject to movement between an open position and a closed position covering said base, and wherein said first and second selectively actuated means are actuated in response to movements of said lid between said positions.
Claim 4
Dependent Claim
42 words
Apparatus as defined in claim 1 wherein: said platform is provided with a recessed circular area for caddy reception, which recessed area includes a central opening dimensioned to permit passage of a caddy cover therethrough while precluding passage of a caddy ring.
