are moved in the direction in which they approach each other (in the directions of arrows C1 and C2). That is, a grasping motion is started.

Then, as the take-out arm 25.26 moves, the fitting recesses 25a', 26a' fit into the gripped portions 19.19, and along with this fitting, the gripping rollers 27,
28 abuts the inclined surface 21.21.

Since the take-out arm 25.26 continues to move even after the gripping rollers 27, 28 come into contact with the inclined surface 21.21, the gripping rollers 27.28 hold the disk holder 15 through the inclined surface 21.21. The lock protrusion 20 is moved forward (in the direction of the arrow) against the temporary spring 12 and locks against the mouth/knot 13.
At the same time, the ejection arm 25.26Iri engages the engagement protrusion 22 when descending the inclined surface 21.2'l, and as a result, the ejection arm 25.26Iri grips the grasped portion 19.19 5d and grasps the disc holder 15. (See Figure 5).

When the gripping operation of the disc holder 15 by the ejecting arm is completed in this way, the disc ejecting mechanism moves the ejecting arm 25 under the control of the control circuit at such timing.
．． 26 start moving in the direction of the passage 5. That is, the extraction operation is started.

In accordance with the start of this ejecting operation, the disc holder 15L/i slides (forward movement) on the shelf board 10 in the direction of arrow B along the guide ribs 14.14, which are unlocked from the lock element 13, and Passage 5 from the side open edge of the plate 10
Inside, the reproducing unit 6 is moved to a position corresponding to the upper surface of the reproducing unit 6 which has been moved to a predetermined position as described above, and at the same position, the ejecting arms 25 and 26 are moved downward by the actuating means under the control of the control circuit. It is placed on the reproduction unit 6 by pivoting.

In the process of placing the disc holder 15 on the playback unit 6 as the ejecting arm pivots, the playback unit 6
The upper turntable 7 passes through the first passage 17 of the disc holder 15, and when the disc holder 15 is completely placed, the disc D inside the disc holder 15 is inserted.
is supported at the center of its upper surface.

Then, place the disc holder 1 onto the playback unit 6.

5.26 are moved away from each other to release the gripping operation of the disk holder 15, and at the timing of completion of such release, the ejection arms 25.26 are again operated by the actuating means, so that the distal end portions 25a, 26a and is then pivoted upwardly to lift it into its raised position.

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

When the performance is finished, the control circuit operates at the timing to cause the operating means to pivot the ejecting arms 25 and 26 downward and move them toward the disc holder again. 15 w4'
f! let

When the ejecting arm completes the gripping operation of the disc holder 15 again, at that timing, the ejecting arms 25 and 26 are pivoted upward while gripping the disc holder 15 according to the operation of the actuating means (the disc holder 15 or the playback unit 6), and then the disk ejector groove and the disk storage device 3 are moved toward the direction of the disk storage device 3, and the disk holder 15 is slid (backward movement) in the direction of arrow B.

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

By this storage operation, the disc holder 15 again reaches above the shelf board 10 from the open side edge of the shelf board 10, and slides along the guide ribs 14.14.

Then, the disk holder 15 is attached to the peripheral wall 11b of the shelf board 10.
When it comes into contact with K, the take-out arms 25 and 26 are turned back or stopped under the control of the control circuit at such timing (
(See Figure 5).

At the timing of this stop of the take-out arms 25, 26, the take-out arms 25, 26 continue to move in the direction opposite to each other under the control of the control circuit. That is, the gripping operation is released.

Then, as the gripping operation is released, the disc holder 151-1 is pushed back (in the direction of the arrow) by the biasing force of the leaf spring 12. As a result.

As shown in FIG. 4, the VC lock protrusion 20 returns to the state in which it is engaged with the lock element 13 of the shelf board 10.

In the above description of the operation, a description has been given of taking out the disc holder from the disc storage device 3, but when taking out the disc holder from the disc storage device 4, the same operation can be performed. However, in this case, the disc holder 15i is designed to be locked to a locking element on the shelf board on the disc storage device 4 side using its lock protrusions 20', 20'.

Effects of the Present Invention Since the present invention is constructed as described above, it is possible to completely accommodate a disc in a disc holder, and also to securely place such a disc holder on a shelf board. This is an excellent invention.
