At this time, the contact portion 48a of the leaf spring 48 is inserted into the elongated hole 42 of the top plate portion 21. The elastic force of the upper and lower leaf springs 48 urges the plurality of steel balls 9 inserted into the elongated hole 10 and the hole 34 of the magazine structure 20 toward each other in the crimping direction.

The assembly of the magazine 18 is thus completed. Next, a usage example will be explained.

First, the user selects the trays 1A and 1 of the magazine 18.
B, 1C, ... When setting disk 2 on 1F, as shown in Fig. 2, set the desired tray 1.
A, 1B, 1C, ... 1F, for example, tray 1A
When the tray 1A is pulled out backward by hooking the finger on the finger hook 17, the tray 1A rotates to the left about the pin 8 and is pulled out to the rear of the magazine 18.

At this time, as described above, the positions of the finger hooks 17 stacked up and down are shifted from each other in the front-back direction, and the radii of the finger hooks 17 from the shaft hole 7 (pin 8) are alternately different. As tray 1A rotates, fingers move to other trays 1B, 1C,...
...With one touch, only the desired tray 1A can be smoothly pulled out without touching the finger hook 17 on the 1F. The amount by which the trays 1B, 1C, . As a result, a part of the outer periphery of the tray 3 of the pulled out tray 1A is covered with the top plate part 21, the bottom plate part 22, the other trays 1B, 1C, . . .
...coinciding with the arc-shaped notches 43 and 15a formed at the rear edge of 1F and corresponding to the outer periphery of the disk 2.

Next, predetermined trays 1A, 1B, 1C,...1
The operation when F is pulled out will be explained with reference to FIGS. 4 and 5. For example, tray 1D
When the steel balls 9 are pulled out, the upper and lower steel balls 9 located in the elongated hole 10 are pushed apart from each other in the vertical direction by the peripheral portion 11. Therefore, the steel balls 9 are connected to the trays 1A, 1B, 1C, 1E, 1F and the partition plate 30.
Tray 1D moves between
A, 1B, 1C, 1E, and 1F are locked so that they cannot be moved.

Next, on the loading section 3 of the pulled out tray 1D,
After placing the disk 2, when the tray 1D is pushed back to its original direction, the guide portion 12 of the tray 1D
It is guided by the partition groove 24 of the magazine structure 19 and is housed in the magazine 18 . Further, the upper and lower steel balls 9 fall into the elongated holes 10 of the tray 1D and are clicked. At this time, the upper outer surface of the disk 2 is pressed by the lower surface of the partition plate 23, and the upper outer surface on the opposite side is also pressed by the lower surface of the partition plate 30, thereby eliminating vertical wobbling of the disk 2. Furthermore, if the radii of the arcuate portions 25, 32 of the partition plates 23, 30 are set to predetermined dimensions, the partition plates 23, 30 will press against the outer periphery of the information recording surface of the disk 2, thereby damaging the information recording surface. Never.

Furthermore, two trays 1A, 1B, 1C,...1
Even if you try to pull out trays F at the same time, the trays 1A and
1B, 1C, . . . 1F, the force is in a direction that compresses the steel ball 9, so it cannot be pulled out. Furthermore, when an external force is applied, such as by shaking the magazine 18, it becomes a force to pull out the trays 1A, 1B, 1C, ... 1F, and similarly compresses the steel balls 9. ,1B,1C,...
...1F will not protrude. Also, when stored, the thick portions 15 of the trays 1A, 1B, 1C, ... 1F
closes the opening 38 of the magazine 18, thereby protecting it from intrusion of dust.

Next, when performing an automatic performance, as shown in FIG. 6, when the magazine 18 is inserted into the player body (not shown), the lock portion 4 is
Fix 4. Then, when a predetermined disk 2 is specified, a sub-chassis (not shown) moves up and down in a stepwise manner, and the tray 1A on which the disk 2 is placed,
1B, 1C, ... Stops at the 1F position. Here, the drive plate 52 rotates, and the arm 52 at one end thereof
a is an opening 38 formed in the side surface of the magazine 18;
Predetermined trays 1A, 1B, 1C, . . . , 1F are pushed out and rotated to a stopper 53. On this occasion,
Guide part 1 of trays 1A, 1B, 1C,...1F
2 is guided by a guide 49 and then reaches a guide 51, where the correct height is maintained throughout.

Then, in the performance section, a clamper (not shown) enters the opening 4 from below, pushes the disk 2 upward from the mounting section 3, presses it against the turntable fixed to the rotating shaft of the spindle motor, and rotates the disk. At the same time, by a pick-up (not shown),
Recorded information on disk 2 is read. Incidentally, when the disk 2 moves up and down, the arcuate parts 15a and 43 formed at the rear end of the magazine 18 and the other trays 1A, 1B, 1C, . .

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