The detailed description of the operation is omitted because it overlaps with the operation described above. Further, the sub-tray on which the disc is placed is indicated by the diagonal lines.

FIG. 17 shows a state in which the sub-tray 23 ₁ is stored in the main tray 30 located inside the player 1, and the sub-trays 23 ₂ to 23 ₆ are stored in the stocker 20. It should be noted that this state is the same as that of FIGS. 1 to 3, and the disk reproducing mechanism including an optical head, a turntable, etc.
Indicated by

Here, when a required operation button is operated to store the disc in the stocker 20, the sub tray 23 ₁
Is stored in the uppermost stage of the stocker 20 (FIG. 18), and the stocker 20 is moved a required distance upward in the drawing (FIG. 19).
Sub tray 23 ₂ stored in the second stage of the stocker 20
20 is moved into the main tray 30 (FIG. 20), and then the main tray 30 is projected to the outside of the player 1. In this state, place the disc on the sub-tray 23 ₂ (Fig. 21),
After moving the main tray 30 into the player 1,
The sub-tray 23 ₂ is stored in the second stage of the stocker 20 (FIG. 22). Subsequently, the stocker 20 is moved upward by a required distance in the drawing, and the sub-tray 23 ₃ stored in the third stage of the stocker 20 is brought into the main tray 30 at a movable position (FIG. 23). By continuously performing the above operation, the discs are loaded on the sub trays 23 ₂ to 23 _6.
Stores one sheet.

In the above embodiment, the control circuit 120 shown in FIG. 1 controls the drive sources 121 to 1 so that the player 1 is always in the state shown in FIG.
25 is controlled. Therefore, when playing a disc that is not housed in the player 1, simply play the main tray 3
It suffices that 0 be projected from the player 1, and the responsiveness and operability are the same as those of a player having no changer function. However, when the disc stored in the stocker 20 is reproduced, the sub-tray 23 ₁ is once stored in the uppermost stage of the stocker 20,
After moving the stocker 20 up and down, it is necessary to move the sub-tray on which the desired disk is placed into the main tray 30.

Therefore, when importance is attached to the responsiveness and operability when reproducing the disc stored in the stocker 20, the control unit 120 controls each drive source 121 so that the player 1 is always in the state of FIG. 18 in the initial state. Control ~ 125. In this case, when the disc stored in the stocker 20 is reproduced, the vertical movement of the stocker 20 is the first operation,
It is possible to improve the response speed with respect to the above embodiment.

In the above embodiment, the player 1
The control circuit 12 prevents the sub-tray 23 _{1 from} being stored in the stocker 20 with the disk placed thereon.
It is controlled by 0. This is the sub trays 23 ₁ to 23 ₆ in which the discs are placed in the stocker 20.
When playing a disc that is not stored in the player 1 in the state where the main tray 30 is stored, the main tray 30 must be projected from the player 1 while one of the sub-trays on which the disc is placed is stored in the main tray 30. This is because the operator is obliged to replace the disk because it must be done. That is, the sub-tray 23 ₁ mounts the disc only when reproducing the disc not housed in the player 1.

However, if the storage capacity of the disc inside the player 1 is emphasized, it is possible to place the disc on all six sub-trays and store it in the stocker 20. In this case, when playing back a disc that is not stored in the stocker 20, if the sub-tray on which the disc is placed and the sub-tray on which the disc is not placed are mixed in the stocker 20, the stocker 2
Of the sub-trays stored in 0, the sub-tray on which no disc is placed is detected by the required detection means,
After storing this sub-tray in the main tray, it is projected from the player 1. If all the sub trays stored in the stocker 20 are loaded with discs, after storing one of the sub trays in the main tray,
An operator carries out a disc replacement operation by projecting the disc from the player 1.

The present invention can be moved between the eject position, the reproduction position and the storage position by directly applying a driving force to the disc without using the main tray or the sub-tray described in the above embodiment. is there. Further, it goes without saying that various modes can be adopted, such as the disk transfer between the eject position, the reproduction position, and the storage position can be configured by the same transfer means.

[0043]

As described above, according to the present invention, the operation of accommodating a plurality of discs inside the player is performed mechanically and does not involve the hands of the operator, so the discs may be soiled or damaged. The storage work can be performed without the need. Further, since the transfer of the disc inside the player is performed on the same plane, the transfer of the disc can be smoothly performed without time loss.
