[Action]

Therefore, when the recording medium at the position opposite to the storage position of the recording medium being reproduced is reproduced next, the recording medium storage case storing the recording medium to be reproduced next is pulled out by the take-out mechanism. Since the recording medium storage case that has been completed can be pushed back, the number of operation steps can be reduced. Further, by using the repulsion and absorbing force of the permanent magnet, it is possible to perform the pulling out and the storing at the same time as the insertion and removal of the T-shaped hook described above.

〔Example〕

An embodiment in which a disk is used as a recording medium according to the present invention will be described with reference to the schematic configuration diagrams of FIGS. 1 and 2.

The description is simplified because it is the same as the conventional example except for the attaching / detaching mechanism part of the drawer mechanism and the disk storage case.

In the figure, a loading / unloading mechanism 4 is slidably supported on a guide rail 3 of a transport mechanism 2 supported by a central portion of a base 1 so as to be capable of moving up and down. On both sides of the loading / unloading mechanism 4, disk storage parts 5a, 5b are erected, and disk storage cases 6a, 6b, etc. in which optical disks (not shown) are stored in the disk storage parts 5a, 5b are arranged in multiple stages. ing. Then, the disc storage case 6a is pulled out from the disc storage portion 5a by the loading / unloading mechanism 4, placed at a predetermined position of the transport mechanism 2, and then the transport mechanism 2 is lowered to the bottom as it is, and the player is placed at the corresponding portion of the bottom. The information on the optical disk is reproduced by the section 7.

As shown in FIG. 2, the attaching / detaching mechanism of the disc loading / unloading mechanism 4 and the disc storage case 6a of the disc exchanging device is provided with the stepping motor 8 which rotates by 90 degrees and the rotation of the stepping motor 8. T-shaped hooks 9a and 9b are arranged on both sides of the shaft in a positional relationship orthogonal to each other. Then, the T-shaped hooks 9a, 9b rotate the stepping motor 8 so that the T-shaped hooks 9a, 9b have a positional relationship substantially orthogonal to or parallel to the disk storage cases 6a, 6b, etc. Engages with the V-shaped recesses 10a, 10b and the like.

In order to reproduce a desired optical disc by the disc exchanging device having the above-mentioned structure, first, the transport mechanism 2 is moved up and down to store the desired optical disc.
Located in front of 6a. Next, the loading / unloading mechanism 4 slides on the transport mechanism 2 and moves toward the disk storage case 6a. At this time, the T-shaped hook 9a has a positional relationship substantially orthogonal to the disk storage case 6a,
It passes through the notch 11a of the T-shaped recess 10a of 6a. When the loading / unloading mechanism 4 is stopped at a predetermined position, the stepping motor 8 is rotated and the T-shaped hook 9a is moved to the disk storage case 6a.
The T-shaped recesses 10a are in substantially parallel positions and are engaged and connected.

Subsequently, the loading / unloading mechanism 4 pulls out the disk storage case 6a from the disk storage portion 5a and moves it to a predetermined position of the transport mechanism 2. At this time, the T-shaped hook 9b passes through the notch 11b of the disk storage case 6b as shown in FIG. 3 and is positioned in the T-shaped recess 10b without contact. Then, the transport mechanism 2 descends with the disk storage case 6a placed, and is set in the player section 7 at the bottom to reproduce information. When the reproduction is completed, the operation reverse to the above-described operation procedure is performed, and the disc storage case 6a is returned to the original position.

However, when the disc storage case facing the storage position of the optical disc being reproduced is pulled out, as in the case where the next optical disc to be reproduced is contained in the disc storage case 6b, before the storage mechanism 4 starts the storage operation. Then, the stepping motor 8 is rotated 90 degrees to connect the T-shaped concave portion 10b of the disk storage case 6b and the T-shaped hook 9b.
Then, in the T-shaped concave portion 10a of the disk storage case 6a, the T-shaped hooks 9a are at positions substantially orthogonal to each other, and the ejecting mechanism 4 pulls out the disk storage case 6b while pushing in the disk storage case 6a to store the respective disk storage. Stop when the cases 6a, 6b have reached the predetermined positions. Then, the next optical disk is set in the player section 7 by the same operation procedure as described above.

As another embodiment, as shown in FIG. 4, the attraction force or repulsive force of the permanent magnet may be used instead of the connecting means by the T-shaped hook or the T-shaped recess. In the figure, a stepping motor 12 mounted on the loading / unloading mechanism 4 has rod-shaped first permanent magnets 14a, 14b at both ends of a rotary shaft 13 extending in the loading / unloading direction. Are arranged so as to be orthogonal to each other and parallel to each other, and the magnetic poles facing each other are arranged to be the same pole. Further, the second permanent magnets 16a, which have rod-shaped magnetic poles at both ends, are also provided on the end faces of the disk storage cases 15a, 15b which engage with the first permanent magnets 14a, 14b.
16b is attached and fixed, and by rotating the stepping motor 12 by 180 degrees, the disc storage cases 15a and 15b are attached or detached by being attracted or repelled. As in the case of the above embodiment, when the optical disk to be reproduced next is stored in the disk storage case facing the storage position of the optical disk currently being reproduced, the stepping motor is started before the storage operation of the loading / unloading mechanism 4. Rotate 12 180 degrees,
The first permanent magnet 14b is attracted to the second permanent magnet 16b of the disk storage case 15b, and the second permanent magnet 16a and the first permanent magnet 14a of the disk storage case 15a repel each other, and When the sliding operation starts, the disc storage case 15a is pushed back and the disc storage case 15b is set at a predetermined position.

〔The invention's effect〕

According to the present invention, the mechanism for attaching / detaching the take-in / out mechanism and the recording medium storage case can have a simple structure. Further, when the recording medium storage case opposite to the storage position of the recording medium being reproduced is next reproduced, it is possible to reduce the operation steps of the loading / unloading mechanism, so that the access time can be shortened.
