DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a CD or a CD-ROM.
The present invention relates to a disc changer for storing a plurality of discs (disk-shaped recording media) and automatically setting a selected disc in a disc drive (recording / reproducing device / optical pickup). More specifically, the present invention relates to a disc changer that stores a plurality of discs mounted on a carriage and automatically changes the discs by moving the carriage in horizontal and vertical planes.

[0002]

2. Description of the Related Art Conventionally, as a disc changer having a simple structure in which about three or four discs are stocked and can be automatically replaced, for example, a rotating disc tray shown in FIG. Is known. This carousel type disc changer is disclosed in, for example,
For example, the disk tray 101 on which a plurality of disks are placed is rotated to move the selected disk to the position of the optical pickup. In this disc changer, a plurality of recesses 102,..., 102 on which discs are placed are provided on the upper surface of a disc-shaped disc tray 101 so as not to overlap. Then, the optical pickup (not shown) moves up and down at the reproducing position, passes through the through hole 103 provided in the concave portion 102, and sandwiches the disc with a clamper (not shown) disposed above the disc tray 101. It is provided so as to be attached and held. The exchange of the performance disk in the disk changer is performed by rotating the disk tray 101 and moving the selected disk to the reproduction position while the optical pickup is lowered below the disk tray 101 and retracted. .

In the case of the disc changer having such a structure, the disc tray 101 needs to have a high degree of flatness by preventing warpage or the like in order to prevent the disc tray 101 from rubbing against the chassis 104 of the disc reproducing apparatus when it is rotated. There is. Therefore, it has been practiced to provide a reinforcing rib for obtaining sufficient rigidity to prevent the warp, thereby increasing the apparent thickness and height dimension. Also, the disc tray 101
Is provided so as to rotate stably on a chassis supported by rollers or the like so as to rotate stably in a horizontal plane.

[0004]

The object of the invention is to be Solved However, according to this disc changer, the one de I Sukutorei 1
Since the discs are placed on the disc 01 so as not to overlap and are stocked, as the number of stocked discs increases, the external dimensions (width × depth) of the apparatus increase, and there is a problem in that space is taken up. For example, even when only three disks are stocked, the external dimensions of the apparatus are at least twice the disk diameter and area in the width and depth directions, respectively.
You need more than twice.

[0005] In addition, the disk tray 101 on which a plurality of disks are placed on one plane is a large molded part requiring surface accuracy, so that the cost is high. In addition, the conventional disc changer requires supporting parts such as rollers to rotate the disc tray 101 smoothly, which increases the number of parts and leads to an increase in cost.

In addition, the disk tray 101 must be formed thick enough to obtain sufficient strength to eliminate warpage, which increases the size of the disk reproducing apparatus. In addition, since the pickup itself is moved up and down with respect to the disk, a space for the movement and an elevating mechanism are required, and there is a problem that the dimension in the height direction becomes large.

Further, in the case of a cartridge type disc changer in which a plurality of discs are stacked and stored as disclosed in Japanese Patent Application Laid-Open No. 4-38657, a disc and a carriage are stacked and stored behind a pickup. There was a disadvantage that the disc could not be removed or replaced during the performance.

SUMMARY OF THE INVENTION An object of the present invention is to provide a low-cost disk changer in which the same number of disks can be stored, the outer diameter can be made smaller and the height can be made smaller than before. More specifically, an object of the present invention is to provide an inexpensive disk changer that can be reduced in height and can be reduced in size as a whole when storing about three disks. It is another object of the present invention to provide a disc changer that allows another disc to be taken out or replaced even during a performance.

[0009]

In order to achieve the above object, a disk changer according to the present invention reciprocates between a carriage for mounting a disk, a plurality of the carriages, and a disk pickup position and a storage position. A tray, a disk drive for recording and reproducing the disk,
Moving the plurality of single disks on the carriage by vertically moving the disk drive loaded position or de-disc unloading position of the lowermost carriage and the same level of I disk storage position of the carriage with respect to the disc drive A disk setting mechanism, a carriage elevating mechanism for elevating and lowering a carriage at a disk storage position and a drive position where a disk drive is disposed above the disk non-loading position of the disk setting mechanism, and a storage position by the operation of the carriage elevating mechanism Or, a carriage moving mechanism for moving the carriage to a space formed at any of the drive positions.

[0010] Therefore, the performance disk is exchanged above the carriage on which the disk selected from the stocked disks or the disk newly loaded on the carriage at the storage position for performance is loaded. Alternatively, the disk located at the disk drive loading position is taken out of the disk drive and moved to a lower position.
In other words, the disk at the disk drive loading position is moved onto a carriage which is raised by driving the disk setting mechanism, and the disk is moved from the disk drive to the disk non-loading position, or the carriage is moved upward by the carriage lifting mechanism. Then, a space for one carriage is left at a drive position on the inner side of the carriage in which the selected disk in the disk storage position is stored. Then, the carriage containing the disk selected at the disk storage position is moved to this space by the carriage moving mechanism. Next, the carriage in the disk storage position at the same level as the carriage containing the disk removed from the disk drive moves to the space created in the disk storage position by the carriage movement to the drive position on the back side of the apparatus, and further, The carriage containing the disk removed from the disk drive into the created space is moved by driving the carriage moving mechanism. Thereafter, the carriage for storing the selected disk at the drive position is moved by the carriage elevating mechanism and / or the carriage.
Or by driving the disk set mechanism, toward the disk drive to move (drop), further only the drop carriage to leave behind to Disk disk on the disk drive in the disk drive loading position. At this time,
Disks on de disk drives are clamped between the clamper descending together with the carriage. Then, reproduction of the disk or recording on the disk is performed by driving the disk drive.

Further, the disc changer of the present invention comprises:
The disk drive is arranged on the back side, and the carriage is arranged on the near side so as to overlap. In this case, it is possible to exchange the disk stocked in front of the tray by pulling out the tray even during the performance.

Then, the first carriage 1 enters under the third carriage 1 (see FIG. 9). Thereafter, the second carriage 1 at the drive position 10 starts descending (see FIG. 10), and descends until it reaches the same height as the first carriage 1 (FIG. 11). The lowering of the second carriage 1 is performed by driving the carriage elevating mechanism 5 at the drive position 10. This ends change mode.

Further, when the clamper arm 20 descends, the clamper 19 descends and the lifter 26 is pushed down (see FIG. 12).

The second carriage 1 and the lifter 26 are lowered together with the clamper 19, and the second disk 7 is clamped on the turntable. Then, the play mode was set again, and the disc exchange was completed (see FIG. 13). When changing from the first disk 7 to the third disk 7, the first carriage 1 receiving the first disk 7 from the disk drive 3 does not stop in the state of FIG. 8 → 7 → 6 → 5 → 4 →
13 (FIG. 11) → FIG. 12 → FIG. 13 and the carriage moves counterclockwise.

Next, the second,
The operation of taking out the third disk 7 and replacing it during a performance or the like will be described. FIG. 14 shows the same state as FIG.
Here, when the operation key [OPEN] is pressed to open the tray 2, the tray 2 pops out by motor drive (FIG. 1).
5), the tray 2 is fully opened (see FIG. 16). Thus, the second disk 7 can be taken out. If [CLOSE] is pressed here, the tray 2 is pulled into the apparatus and returns to the state of FIG. In order to remove the third disk 7, when [OPEN] is pressed again, the pin gear 15 of the carriage moving mechanism 6 in the upper row is rotated to move the second carriage 1 to the star gear on the back side of the tray. Move over 31. At this time, the second carriage 1 slides and moves on the tooth surfaces of the star gear 22 on the front side of the tray and the star gear 31 on the rear side of the tray.

Thus, the upper part of the third carriage 1 is opened, and the third disk 7 can be taken out. When [CLOSE] is pressed here, the pin gear 15 of the carriage moving mechanism 6 in the upper row rotates again in the opposite direction to the above, pulls the second carriage back toward the tray, and returns to the state of FIG.

The above embodiment is a preferred embodiment of the present invention, but the present invention is not limited to this embodiment, and various modifications can be made without departing from the gist of the present invention. For example, in this embodiment, three disks can be exchanged. However, the present invention is not particularly limited to this, and two, four, or more disks can be stocked. However, when storing about three discs, it is possible to provide a disc changer that is simplest in structure, inexpensive, low in height, and small overall.

Further, in this embodiment, the disc is a CD.
However, the present invention is not particularly limited thereto, and other recording media such as a CD-ROM and an MO can be reproduced.

[0031]
