Multiple compact disk carousel mechanism
First Claim
1. A disk loading and unloading apparatus for loading and unloading informational disks into a multiple disk player, said apparatus comprising:
- a loading drawer adapted to be opened for loading disks by a user, and adapted to be closed in preparation for said disk player to play loaded disks;
a motorized rotational arm member;
a pin member coupled to said rotational arm member; and
a pin member guide slot attached to said loading drawer which slidably receives said pin member;
wherein said pin member guide slot has a contour which provides an interplay between said pin member and the boundaries of said guide slot, facilitating opening and closing of said loading drawer when said rotational arm member is rotated, said contour comprising two end regions, one on each side of a curved middle region, said end regions providing drawer movement between open and closed positions and vice versa, said middle region providing drawer dwell and locking states for locking said drawer in a predetermined open loading drawer position and in a predetermined closed drawer position;
a pivotally mounted pickup bracket for raising and lowering a disk mounted thereon; and
a rotatable locking index coupled to a non-pivoting end of said pickup bracket, and operatively coupled to said rotational arm member;
wherein rotation of said locking index in a first direction causes said non-pivoting end of said pickup bracket to be raised, and rotation of said locking index in a second direction causes said non-pivoting end of said pickup bracket to be lowered.

Abstract
A multiple compact disk (CD) carousel mechanism for a CD player has a novel loading drawer mechanism employing the combination of a pin arm and a uniquely configured drawer guide slot (within which a pin attached to the end of the pin arm travels) attached to the underside of the drawer for carrying out the following operations: drawer opening; drawer locking in the opened position; drawer closing; and drawer locking in the closed position. The improved design obviates the need for prior art rack and pinion gears for drawer movement, and also obviates the need for separate prior art drawer lock-in and drawer lock-out mechanisms (requiring additional springs, levers and gears).
