Abstract

Abstract An autochanger type disc player for playing compact audio discs includes a disc storage area able to store a plurality of closely spaced discs, a disc playing mechanism, and a mechanism for transferring a selected disc from the disc storage area to the disc playing mechanism. During transfer of the selected disc from the disc storage area to the disc playing mechanism, the selected disc passes through a disc inlet that includes a restraining member permitting only the selected disc to pass through to the disc playing mechanism and a buffer part preventing the recorded portion of the disc from contacting non-resilient components of the disc player.

Claim 3
Dependent Claim 37 words
The disc player of claim 1, wherein said disc inlet is V-shaped and said restraining member is positioned above the bottom of said disc inlet by a distance less than the radius of one of said discs.
Claim 4
Dependent Claim 47 words
The disc player of claim 1, wherein said disc inlet is V-shaped and said restraining member extends from the bottom of said disc inlet to a point positioned above said bottom of said disc inlet by a distance less than the radius of one of said discs.
Claim 5
Dependent Claim 41 words
The disc player of claim 1, wherein discs are recorded on one side only and said restraining member is connected to the side of said disc inlet corresponding to the recorded side of said selected disc passing through said disc inlet.
Claim 6
Dependent Claim 40 words
The disc player of claim 1, wherein said restraining means includes two restraining members, each connected to an individual side of said disc inlet and projecting from said forward face portion of said disc guide toward said disc storing means.
Claim 7
Dependent Claim 164 words
An autochanger type disc player, comprising: means for storing a plurality of closely spaced, parallel discs; means for playing said discs; means for transferring a selected one of said discs from said disc storing means to said disc playing means, said disc transferring means being movable along said plurality of discs in said disc storing means and including a disc guide having a disc inlet alignable with said selected disc in said disc storing means, said selected disc passing through said disc inlet during transfer of said selected disc from said disc storing means to said disc playing means; and buffer means for preventing the recorded portion of said selected disc from contacting non-resilient portions of said disc player when said selected disc is being transferred from said disc storing means to said disc playing means, said buffer means including a buffer part formed of a resilient material projecting from one side of said disc inlet approximately to the center of said disc inlet.
Claim 8
Dependent Claim 164 words
An autochanger type disc player, comprising: means for storing a plurality of closely spaced, parallel discs; means for playing said discs; means for transferring a selected one of said discs from said disc storing means to said disc playing means, said disc transferring means being movable along said plurality of discs in said disc storing means and including a disc guide having a disc inlet alignable with said selected disc in said disc storing means, said selected disc passing through said disc inlet during transfer of said selected disc from said disc storing means to said disc playing means; and buffer means for preventing the recorded portion of said selected disc from contacting non-resilient portions of said disc player when said selected disc is being transferred from said disc storing means to said disc playing means, said buffer means including a buffer part formed of a resilient material projecting from one side of said disc inlet approximately to the center of said disc inlet.
