Abstract
Abstract The embodiment of the invention disclosed herein is directed to a record selector mechanism which includes a plurality of spaced-apart records to be individually selected from their storage position and transported to a playing position. The record selector mechanism has an arcuately movable playing station which scans the plurality of positions occupied by the records located in a storage position. The system also includes means for removing the record from the storage position and inserting it into rotating means for playing the record while the playing station remains in registry with the storage position. The rotating means includes diametrically opposed friction surfaces which are slightly angled relative to one another and include means to effect self-centering of the record. A slide pointer is mounted for arcuate movement at the exterior of a housing and positioned in registry with one of a plurality of locations for selecting a desired record associated with that location and identified by indicia means at that location.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
144 words
In a phonograph system the combination comprising: first and second spaced-apart resilient disk means having opposed frictional surfaces for engaging opposite faces of a disk type record therebetween, said frictional surfaces engaging the faces of said record and rotationally driving said record prior to centering thereof, drive means engageable with at least one of said spaced-apart disk means for driving said disk means and said record placed therebetween at playing speed, coarse means for placing the center of said record within close proximity of said spaced-apart disk means, dynamic self-centering means formed on said disk means and engageable with the faces of a record to effect self-centering of said record upon rotation of said disk means and said record, transducer means engageable with said record for reproducing the information thereon, and reproducing means for producing an audio output of the information on said record.
Claim 2
Dependent Claim
144 words
In a phonograph system the combination comprising: first and second spaced-apart resilient disk means having opposed frictional surfaces for engaging opposite faces of a disk type record therebetween, said frictional surfaces engaging the faces of said record and rotationally driving said record prior to centering thereof, drive means engageable with at least one of said spaced-apart disk means for driving said disk means and said record placed therebetween at playing speed, coarse means for placing the center of said record within close proximity of said spaced-apart disk means, dynamic self-centering means formed on said disk means and engageable with the faces of a record to effect self-centering of said record upon rotation of said disk means and said record, transducer means engageable with said record for reproducing the information thereon, and reproducing means for producing an audio output of the information on said record.
Claim 3
Dependent Claim
96 words
In the phonograph system as set forth in claim 1 wherein said coarse alignment means includes means for engaging the peripheral edge of said record before centering thereof as it rotates with said first and second disk means for urging radial components of said peripheral edge which extend a distance greater than the radius of said record inwardly toward the center of said disk means, said coarse alignment means being spaced from the central axis of said disk means a distance greater than the radius of the maximum radius record to be inserted therebetween and played.
Claim 4
Dependent Claim
35 words
In the phonograph system as set forth in claim 1 wherein said one of said disk means is provided with resilient rubber-like material and the other of said disks is provided with resilient fibrous material.
Claim 5
Dependent Claim
36 words
In the phonograph system as set forth in claim 3 wherein the resilient fibrous material of said other disk means is sculptured to form a central hub to fit into the center aperture of said record.
Claim 6
Dependent Claim
34 words
In the phonograph system as set forth in claim 4 wherein said disk means rotate about independent axes which are angled relative to one another in the order of about 0.5 to 10 degrees.
Claim 7
Dependent Claim
36 words
In the phonograph system as set forth in claim 1 further including means for inserting said record between said disks by moving the record from a storage position to a playing position between said disk means.
