Next, the tray 1 is inserted into the partition groove 24 of the front magazine structure 19 and the partition groove 31 of the left magazine structure 20, respectively.
The peripheral portion 11 of A, 1B, 1C, ... 1F is inserted, and the shaft hole 7 and the elongated hole 1 formed in the trays 1A, 1B, 1C ,.
0 is aligned with the shaft hole 33 and the hole 34 formed in the left magazine structure 20. After that, the pin 8 is inserted into the aligned shaft holes 7 and 33, and the lower end of the pin 8 is inserted into the hole or the recess 41 of the bottom plate portion 22. At this time, the upper ends of the pins 8 project from the upper surface of the magazine forming body 20.

Moreover, the trays 1A, 1B, 1C, ...
A plurality of steel balls 9 are inserted into the elongated holes 10 of F and the holes 34 of the magazine structure 20. At this time, the joints of the upper and lower steel balls 9 are located in the respective elongated holes 10.

Next, the top plate 21 is placed on the front magazine structure 19 and the left magazine structure 20, and the upper end of the pin 8 is inserted into the hole or the recess 41 of the top plate 21. In addition, the screws 26 and 28 inserted into the small holes 45 and 46 of the top plate portion 21,
The magazine components 19 and 20 are screwed and fixed to the female screw portions 27 and 37. Further, the screw 35 is a small hole 48 of the leaf spring 48.
It is inserted into the small hole 47 of the top plate portion 21 via b and is screwed and fixed to the female screw portion 36 of the left magazine constituting body 20.
At this time, the contact portion 48 a of the leaf spring 48 is inserted into the elongated hole 42 of the top plate portion 21. Then, due to the elastic force of the upper and lower leaf springs 48, the plurality of steel balls 9 inserted into the elongated holes 10 and the holes 34 of the magazine forming body 20 are urged in the crimping direction.

This completes the assembly of the magazine 18. Next, a usage example will be described.

First, the user selects trays 1A, 1B, 1 of the magazine 18
When setting the disc 2 in C, ... 1F, as shown in FIG. 2, desired trays 1A, 1B, 1C ,.
F, for example, when a finger is hooked on the finger hook portion 17 of the tray 1A and pulled out backward, the tray 1A rotates rightward with the pin 8 as a fulcrum, and is pulled out to the front portion of the magazine 18.

At this time, as described above, the finger hooks 17 that are stacked one above the other
The positions of are shifted from each other in the front-rear direction, and the radii from the shaft holes 7 (pins 8) of the finger hooks 17 are made different from each other. Therefore, as the tray 1A rotates, the fingers are moved to other trays. It is possible to smoothly pull out only the desired tray 1A with one touch without touching the finger hooks 17 of 1B, 1C, ... 1F. The trays 1B, 1C, ... 1F are pulled out by the depths of the recessed groove 5 and the left magazine forming body 2
It is limited by the contact with the stopper portion 55 formed on the rear surface of 0. As a result, a part of the outer circumference of the mounting portion 3 of the tray 1A that has been pulled out corresponds to the outer circumference of the top plate portion 21 and the bottom plate portion 22, and the disc 2 formed at the trailing edge of the other trays 1B, 1C, ... 1F. It coincides with the arcuate notches 43 and 15a.

Next, the operation when the predetermined trays 1A, 1B, 1C, ... 1F are pulled out will be described with reference to FIG. 4 and FIG. For example, when the tray 1D is pulled out, the slot 1
The upper and lower steel balls 9 located at 0 are pushed vertically by the peripheral portion 11. For this reason,
The steel balls 9 move between the trays 1A, 1B, 1C, 1E, 1F and the partition plate 30 and are prevented from moving in the returning direction by the peripheral portion 11 of the tray 1D, so that the trays 1A, 1B,
1C, 1E and 1F are locked immovably.

Next, when the disc 2 is placed on the placing portion 3 of the pulled-out tray 1D and the tray 1D is pushed back in the original direction,
The guide portion 12 of the tray 1D is guided by the partition groove 24 of the magazine constructing body 19 and stored in the magazine 18. Further, the upper and lower steel balls 9 drop into the elongated holes 10 of the tray 1D and are clicked. At this time, the outer peripheral upper surface of the disk 2 is pressed by the lower surface of the partition plate 23, and the outer peripheral upper surface on the opposite side is also pressed by the lower surface of the partition plate 30, so that there is no rattling of the upper and lower sides of the disk 2. Further, if the radiuses of the circular arc portions 25 and 32 of the partition plates 23 and 30 are set to predetermined dimensions,
Since the partition plates 23 and 30 press the outer periphery of the information recording surface of the disc 2, the information recording surface is not damaged.

Furthermore, even if two trays 1A, 1B, 1C, ... 1F are to be pulled out at the same time, the trays 1A, 1B, 1C, 1F
Since the force acts to compress the steel ball 9 between them, it cannot be pulled out. Further, even when the magazine 18 is swung, the force is simultaneously applied to the plurality of trays 1A, 1B, 1C, ...
Since it becomes a force to pull out the 1F and also in the direction of compressing the steel ball 9 in the same manner, it is difficult to easily perform the trays 1A, 1B, 1C,
… The 1st floor never jumps out. Also, when stored, Tray 1
The thick portion 15 of A, 1B, 1C, ...
Since it closes the opening 38, it is protected from intrusion of dust.

Next, when performing the automatic performance, as shown in FIG. 6, when the magazine 18 is inserted into the player main body (not shown), the lock 44 is fixed by the lock lever. Then, when a predetermined disk 2 is designated, a sub-chassis (not shown) moves up and down in steps and stops at the positions of the trays 1A, 1B, 1C, ... 1F on which the disk 2 is placed.
Here, the drive plate 52 rotates and the arm 52a at one end thereof rotates.
However, predetermined trays 1A, 1B, 1C, ... 1F are pushed out from the opening 38 formed on the side surface of the magazine 18 and rotated to the stopper 53. At this time, the trays 1A, 1B, 1
The guide portion 12 of C, ..., 1F is guided by the guide 49, then reaches the guide 51, and the correct height is maintained until the end.

Then, in the playing section, a clamper (not shown) penetrates into the opening section 4 from below, pushes up the disk 2 from the mounting section 3 and presses it to a turntable fixed to the rotary shaft of the spindle motor to rotate it. At the same time, the recording information on the disc 2 is read by a pickup (not shown). When the disc 2 moves up and down, the magazine 18 and the notches 15a and 43 formed at the rear ends of the other trays 1A, 1B, 1C, ... 1F form part of guides on the outer periphery of the disc 2.

At the end of the performance, the clamper descends and the disc 2 is placed on the placing portion 3 of the trays 1A, 1B, 1C, ... 1F, and then the drive plate 52 rotates clockwise and the arm 52 at the other end.
b pushes the trays 1A, 1B, 1C, ... 1F back into the magazine 18. Other points are the same as in the case of manual operation.

[Advantages of the Invention] The present invention, as described above, includes a plurality of trays (1A), (1B), (1C) for mounting the disks (2).
And a disc storage container consisting of a magazine (18) for separately storing these, the trays (1A), (1B), (1C) ... are the trays (1A), (1B),
