Description

TECHNICAL FIELD The present invention relates to a disc player, and more particularly to a multi-disc player that can accommodate a plurality of discs and can sequentially select any of the stored discs for continuous performance.

BACKGROUND ART A joke box is generally known as a disk player that can store a plurality of disks and can sequentially select any of the stored disks for continuous performance. However, conventional juice boxes were very large, making them unsuitable for home use.

In recent years, digital audio discs (hereinafter referred to as
(abbreviated as DAD), by recording digital signals, it can accommodate a larger amount of information than conventional audio disks that record analog signals, and generates less noise during playback. Several types of disks have been developed and are widely used.
Among these, disks with an outer diameter of approximately 12 cm, which are generally called compact disks and which record and read signals using laser light, are easy to handle and allow the overall size of the disk player to be made smaller. be. Recently, a multi-disc player has been developed that can store a plurality of small DADs (for example, 5 to 6 discs) at any time and is suitable as a home-use joke box for playing these discs continuously. By the way, the playing time of a small DAD is 1 hour, which is about 1.5 hours longer than a conventional analog audio disk.
It can accommodate twice the amount of information. Therefore,
For example, 6 discs can hold approximately 120 songs with a playing time of around 3 minutes.
It is also easy to cover your favorite genres, such as Jiyaz or Enka.

A multi-disc player basically includes a performance means including a turntable, a pickup, etc.
The player includes a disk holder that holds a disk and is inserted into a mounting portion in the player housing, and a disk ejecting and conveying mechanism that conveys the disk in the disk holder to a performance position, that is, onto a turntable.

In a multi-disc player, when a disk in a disk holder is conveyed onto a turntable, the disk is moved in two directions, for example, in a direction parallel to the disk supporting surface of the turntable and in a direction substantially perpendicular thereto. However, in the already developed multi-disc player, the disk ejecting and conveying mechanism for carrying out this conveyance directly removes the disk in the disk holder, the end of the disk in the direction of protrusion from the disk holder, or almost the entire disk. It is of the type that can be grasped and pulled out of the disc holder, and the configuration of the disc ejecting and transporting mechanism, including the holding mechanism that grips the disc, is large and complex, and the space required for its operation is large, making it difficult for players to It has been difficult to downsize the entire device, and this has led to an increase in cost.

Recently, in an attempt to solve this problem, for example,
No. 60-104310, the disk holders are provided with a housing, arranged within the housing in a direction substantially perpendicular to the disk-carrying surface of the turntable, each carrying a disk on its major surface; A new multi-disc player has been developed that includes a plurality of plate-shaped trays that can protrude from a housing along each main surface.
That is, by simply protruding the plate-shaped trays each carrying a disk from the housing, the disks can be transported in one direction (dake transport in a direction parallel to the disk-supporting surface of the turntable).
It is structured so that this is done. Therefore, in a multi-disc player as described above, a disk housed in a disk holder is directly gripped by the end of the disk in the direction of protrusion from the disk holder or substantially the entire disk by a complicated gripping mechanism to remove the disk from the disk holder. The structure is simpler than that provided with a disc ejecting and transporting mechanism of the type that pulls out the disc, and it becomes easier to reduce the size and cost of the player as a whole.

SUMMARY OF THE INVENTION An object of the present invention is to provide such a multi-disc player that can be further miniaturized.
