Claims
- 1. A disc changer, comprising:
- a housing;
- a disc player in the housing having an engaged playing and a disengaged non-playing state;
- a tray support horizontally movable between an extended disc mounting position and a fixed playing position in the housing;
- a rotation shaft on the tray support;
- a tray rotatable around the rotation shaft so as to have a fixed axis of rotation relative to the tray support, the tray having a plurality of disc carrying areas each for carrying a disc for presentation to the disc player, the disc carrying areas being equally angularly spaced, the tray having a generally polygonal profile and the tray support having a width which is shorter than the effective diameter of the tray;
- a motor within the housing for use in rotating the tray, extending the tray support, and engaging and disengaging the disc player;
- a gear transmission driven by the motor operative alternately to engage and disengage the disc player, extend the tray support, or rotate the tray; and
- a solenoid operative when energized to shift the gear transmission to rotate the tray.
- 2. The disc changer according to claim 1, wherein the width of the tray support is approximately equal to four times a disc radius.
- 3. A disc changer according to claim 1, wherein the solenoid when next energized is operative to shift the gear transmission to engage the disc player.
- 4. A disc changer according to claim 3, wherein the solenoid when energized is operative to release a cam gear.
- 5. A disc changer according to claim 1, wherein the solenoid is operative to shift the gear transmission when the disc player is disengaged to rotate the tray.
- 6. A disc changer according to claim 1, wherein the solenoid is operative when successively energized when the disc player is disengaged to shift the gear transmission to rotate the tray, and then extend the tray support.
- 7. A disc changer according to claim 6, wherein the solenoid when energized is operative to release a cam gear.
- 8. A disc changer according to claim 1, wherein the gear transmission is operative to ensure that the tray is oriented in one of a plurality of predefined positions about its axis of rotation to enable the tray to be extended by the tray support out through a slot in the housing, the slot having a width which is less than the effective diameter of the tray.
