Abstract

Abstract A disk player includes a player housing. A turntable and a plurality of trays in which corresponding disks are detachably placed are disposed in the player housing. The trays are juxtaposed in such a manner that the surfaces of the trays are substantially in parallel with the disk bearing surface of the turntable. The disk player further includes a circular gear section for moving the plurality of trays to a playing position, a waiting position, and an ejecting position; and a drive section for rotating the circular gear section. Further, a circular cam mechanism is engaged with the circular gear so as to be turned thereby, the circular cam mechanism having cam section for moving a pickup section vertically in accordance with the position of the disk at the playing position.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 150 words
A disk player comprising: a player housing; a pickup section disposed within said player housing; a turntable disposed within said player housing and having a disk bearing surface; a plurality of movable trays disposed in said player housing and having surfaces on which corresponding disks are detachably placed, said trays being juxtaposed so that the surfaces of said trays are substantially in parallel with the disk bearing surface of the turntable; a circular gear section for moving each of said plurality of trays to a playing position, a waiting position, and an eject position; a drive section for rotating said circular gear section; and a circular cam mechanism engaged with said circular gear section so as to be turned thereby, said circular cam mechanism having a cam section for moving said pickup section vertically in accordance with the position of a corresponding one of said disks at said playing position.
Claim 2
Dependent Claim 63 words
The disk player as claimed in claim 1, wherein said circular gear section comprises a circular gear and wherein said trays are movably mounted on sub-trays, respectively; said disk player further comprising pinion gears which are rotated by said circular gear and are engaged with said trays and sub-trays so that said trays and sub-trays are moved as said circular gear is rotated.
Claim 3
Dependent Claim 44 words
The disk player as claimed in claim 1, further comprising a clamper section for clamping a corresponding one of said disks, said cam section of said circular cam mechanism moves said clamper section vertically so as to clamp a corresponding one of said disks.
Claim 4
Dependent Claim 44 words
The disk player as claimed in claim 2, further comprising a clamper section for clamping a corresponding one of said disks, said cam section of said circular cam mechanism moves said clamper section vertically so as to clamp a corresponding one of said disks.
Claim 5
Dependent Claim 72 words
The disk player as claimed in claim 3, further comprising a clamper lifting mechanism for moving said clamper section vertically, said clamper lifting mechanism comprising a clamper arm section which supports said clamper section and engages with said cam section of said circular cam mechanism, said circular cam mechanism including a circular cam, so that, as said circular cam turns, said clamper arm section is swung to move said clamper section vertically.
