In order to support the disk D without contacting the bottom surface of the holder hole 16, an inclined support surface 24 is provided to support the outer periphery of the disk D.

The disk holders 15 formed in this manner are each placed on the shelf board 10 so as to engage with the locking element 13 with the lock protrusion 20, as shown in FIG. It is now possible to move forward and backward and left and right.

Reference numerals 25 and 26 designate ejecting arms of a disk ejecting mechanism (not shown) provided at the rear of the disk storage device 3, and as shown in FIG. It has mating recesses 25a', 26a' and gripping rollers 27, 28, respectively, in the recesses.

The ejecting arms 25 and 26 can move toward each other on the disk ejecting mechanism, and can also move in the vertical and horizontal directions at the rear of the disk storage device 3 by the movement of the disk ejecting mechanism itself. It's on.

Effect: The present invention is configured as described above,
The effect will be explained below.

Now, each shelf board 1 of each disk storage device 3, 4
Disk holder 1 containing disk D on top of 0
5 is placed, and when the user operates the disk selection key 2A and performance key 2B on the operation panel 2 in this state, the reproduction unit 6 is selected by the elevator mechanism under the control of a control circuit (not shown). The disc is moved to a predetermined position corresponding to the shelf board 10 on which the disc is placed.

Also, at the same time or before or after this, the disk storage device side (for example, reference numeral 3
The disk ejecting mechanism on the side) moves upward or downward to bring the ejecting arms 25, 26 to a position corresponding to the shelf board 10 on which the selected disk is placed.

This state is shown in FIG. 4. In this state, the disk holder 15 is moved rearward (in the direction of arrow A) by the biasing force of the leaf spring 12 and is locked onto the lock element 13 by the lock protrusion 20. In the standby state, the take-out arms 25 and 26 are prevented from moving in the lateral direction (in the direction of arrow B) toward the passage 5, and the take-out arms 25 and 26 are in their fitting recesses 25a' and 26.
a′ is the gripped portion 19 of the disk holder 15,
19, and the gripping rollers 27, 28 are made to correspond to the slope portion 21 of the gripped portion 19.

Next, at a timing immediately after the state shown in FIG. 4 is reached, the ejecting arms 25 and 26 are moved in a direction toward each other (arrow C1, C2 direction). That is, a grasping motion is started.

As the take-out arms 25, 26 move, the fitting recesses 25a', 26a' move into the gripped portion 1.
9 and 19, and along with this fitting, the gripping rollers 27 and 28 come into contact with the inclined surfaces 21 and 21.

The inclined surfaces 21, 21 of the gripping rollers 27, 28
Since the ejecting arms 25 and 26 continue to move even after contacting the holder, the gripping rollers 27 and 28 move the disk holder 15 forward (in the direction of arrow A) via the inclined surfaces 21 and 21 against the leaf spring 12. ) to release the engagement of the lock protrusion 20 with the lock element 13, and engage the engagement protrusion 22 when descending on the slopes 21, 21, and as a result, the take-out arm 2
5 and 26 are in a state where they grip the disk holder 15 with the gripped parts 19 and 19 (see FIG. 5).

When the gripping operation of the disk holder 15 by the ejecting arm is completed in this manner, the disk ejecting mechanism starts moving the ejecting arms 25 and 26 in the direction of the passage 5 under the control of the control circuit at such timing. That is, the extraction operation is started.

According to the start of this ejecting operation, the locking element 1
The disk holder 15, which is unlocked from the disk holder 3, slides (reciprocates) on the shelf board 10 along the guide ribs 14, 14 in the direction of arrow B, and enters the passage 5 from the open side edge of the shelf board 10. As described above, the extraction arms 25 and 26 are moved to a position corresponding to the upper surface of the regeneration unit 6 which has been moved to a predetermined position, and at the same time, the take-out arms 25 and 26 are pivoted downward by the actuating means under the control of the control circuit at this position. By doing so, it is placed on the reproduction unit 6.

In the process of placing the disc holder 15 on the reproducing unit 6 as the ejecting arm pivots, the turntable 7 on the reproducing unit 6 passes through the first passage 17 of the disc holder 15 and places the disc holder 15 on the disc holder 15. At the timing when the placement is completed, the disk D in the disk holder 15 is supported at the center of its upper surface.

When the disk holder 15 is completely placed on the reproducing unit 6, the take-out arms 25 and 26 are moved away from each other by the operating means under the control of the control circuit at such timing, and the disk holder 15 is released, and at the timing of completion of such release, the above-mentioned take-out arm 2 is again operated by the actuating means.
5, 26 are pivoted upward to lift their tips 25a, 26a, and wait in their lifted position.

This completes the removal of the disk holder 15, and from now on, information is reproduced from the disk D and played by rotating the turntable 7 in the reproduction unit 6 and driving the pickup.

When the performance is finished, the control circuit operates at this timing to cause the operating means to pivot the take-out arms 25 and 26 downward and move them toward the disk holder 15 again. Let them grab it.

When the retrieval arm grips the disk holder 15 again, at that timing, the retrieval arms 25 and 26 are pivoted upward while gripping the disk holder 15 according to the operation of the actuating means. After that, the disk ejecting mechanism moves in the direction of the disk storage device 3, and the disk holder 15 slides in the direction of arrow B (backward movement).

That is, the storage operation of the disk holder 15 is started.

Due to this storage operation, the disk holder 1
5 is the shelf board 10 again from the open side edge of the shelf board 10.
It reaches the top and slides along the guide ribs 14, 14.

Then, when the disk holder 15 comes into contact with the peripheral wall 11b of the shelf board 10, the take-out arms 25, 2 are controlled by the control circuit at such timing.
The backward motion of No. 6 stops (see Figure 5).

At the timing of this stop of the take-out arms 25, 26, the take-out arms 25, 26 are subsequently moved away from each other under the control of the control circuit. That is, the gripping operation is released.

Then, as the gripping operation is released, the disk holder 15 is pushed back (in the direction of arrow A) by the urging force of the leaf spring 12, and as a result,
As shown in FIG. 4, the shelf board 10 is
It returns to the standby state in which the lock element 13 is engaged.

In the above explanation of the operation, the case of taking out the disk holder from the disk storage device 3 has been described, but when taking out the disk holder from the disk storage device 4, the same operation can be performed. Yui,
In this case, the disk holder 15 is configured to be locked to a lock on a shelf board on the side of the disk storage device 4 using its lock protrusions 20', 20'.

<Effects of the present invention> Since the present invention is configured as described above, a disk can be completely accommodated in a disk holder, and such a disk holder can be reliably placed on a shelf board. .

Furthermore, since the disk is housed in a disk holder and the disk holder is taken out from the shelf board, the disk take-out mechanism does not directly touch the disk and the disk is not damaged.

Further, by urging the disk holder placed on the shelf board in a direction to prevent its removal by the urging means, the locking element and the lock part are engaged and the disk holder is locked on the shelf board. In addition, by sliding the disk holder itself in the direction in which the engagement between the lock element and the lock part is released by the disk ejecting mechanism, the disk holder is removed from the shelf board after the engagement is released. Since the disk holder is configured to be taken out, there is no need to provide a complicated locking mechanism for the disk holder and the disk ejecting mechanism, and the disk holder can be locked and unlocked on the shelf board, and removed from the shelf board with an extremely simple configuration. This is an excellent invention that can realize the extraction of .
