Abstract

Abstract A record disk loading and retrieving system is provided in which when a record disk stored in a container is inserted, the record disk is taken out of the container, fixed on a turn table and reproduced by a simple structure, and when the reproduction is ended, a load is applied to the outer periphery of the record disk in a direction to damp the rotation so that the rotation of the record disk is transformed into a thrust in a radial direction by said rotation load so as to retrieve the record disk into the container. There is no need to stop or wait the cease of the rotation of the turn table, but the rotation of the record disk is utilized effectively.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 135 words
A record disk loading and retrieving system comprising: a record disk; a record disk container having an opening on one side for allowing said record disk to go in and out; a turn table for engaging with and rotating said record disk; means for taking said record disk out of said record disk container and transporting the disk onto said turn table; clamp means for detachably engaging said record disk with said turn table; means for contacting the periphery of said record disk rotating on the turn table and applying a damping load for the rotation when said clamp means is released; and guide means for guiding the record disk to the opening of said record disk container utilizing the thrust force generated by the rotation of said record disk subjected to said load means.
Claim 2
Dependent Claim 135 words
A record disk loading and retrieving system comprising: a record disk; a record disk container having an opening on one side for allowing said record disk to go in and out; a turn table for engaging with and rotating said record disk; means for taking said record disk out of said record disk container and transporting the disk onto said turn table; clamp means for detachably engaging said record disk with said turn table; means for contacting the periphery of said record disk rotating on the turn table and applying a damping load for the rotation when said clamp means is released; and guide means for guiding the record disk to the opening of said record disk container utilizing the thrust force generated by the rotation of said record disk subjected to said load means.
Claim 3
Dependent Claim 52 words
A record disk loading and retrieving system according to claim 1, in which said record disk transporting means supports said record disk container above the position for clamping the record disk and tilts said disk container in drawing out the record disk to let the record disk fall down by its weight.
Claim 4
Dependent Claim 61 words
A record disk loading and retrieving system according to claim 1, wherein said container is provided with a cut away portion near said opening, and in which said record disk transporting means includes two rollers to be inserted in said cut away portion and pinch the record disk in the container, at least one of the rollers being driven to rotate.
Claim 5
Dependent Claim 46 words
A record disk loading and retrieving system according to claim 1, further comprising means for detecting that the record disk is retrieved in the disk container; and second transporting means for pushing said record disk into the disk container by the output of said detecting means.
Claim 6
Dependent Claim 39 words
A record disk loading and retrieving system according to claim 1, further comprising means for contacting the record disk rotating on the turn table when the clamp means is released and shifting the record disk to said load means.
Claim 7
Dependent Claim 31 words
A record disk loading and retrieving system according to claim 1, in which said load means having the portion subjected to contact with the record disk formed in a V-shaped groove.
Claim 8
Dependent Claim 32 words
A record disk loading and retrieving system according to claim 1, in which said guide means is disposed in U-shape along the outer periphery of the record disk on the turn table.
Claim 9
Dependent Claim 35 words
A record disk loading and retrieving system according to claim 1, in which said clamp means consists of a smooth tapering projection and a concave portion formed in said turntable to engage with said projection.
Claim 10
Dependent Claim 48 words
A record disk loading and retrieving system according to claim 1, in which said clamp means comprises a concave formed in said turn table, an outer ring member having a projection to fit in said concave, and a clamp releasing shaft for rotatively supporting said outer ring member.
Claim 11
Dependent Claim 46 words
A reCord disk loading and retrieving system according to claim 1, in which said disk container is provided with holes, and said record disk further comprises an opener means for extending the opening of said disk container by engaging with the holes of said disk container.
