BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk exchange device for selectively recording and / or reproducing a plurality of disks stored in a disk storage unit.

[0002]

2. Description of the Related Art Conventionally, in an optical disk reproducing apparatus for reproducing an optical disk, a plurality of optical disks are stored in a tray housing provided in a main body of the apparatus, and one of the optical disks stored in the tray housing is read. 2. Description of the Related Art There is an optical disc reproducing apparatus having a disc exchange function of selectively taking out a disc, mounting the disc on a disc rotation operation unit, and reproducing information signals such as a tone signal recorded on an optical disc. An example of this type of optical disk reproducing apparatus is an automatic record exchange apparatus disclosed in Japanese Patent Publication No. 7-58577.

This automatic record exchanging apparatus includes a magazine in which records are stored, a loading / reproducing mechanism for storing and reproducing records transferred from the magazine, and a first magazine.
Installation means for installation so as to be pivotable about the axis of
Mounting means for pivotally mounting the loading / reproducing mechanism about a second axis separate from the first axis, and displacing the magazine and the loading / reproducing mechanism with equal angular displacement in opposite directions about the respective axes. Moving means for moving to a plurality of predetermined angular positions. In such an automatic record exchange apparatus, at each of a plurality of predetermined angular positions, the loading / playback mechanism is aligned with one storage section for storing records in the magazine, and the magazine and the loading / playback mechanism are aligned. And the selected record can be transported between them.

[0004]

However, the above-described automatic record exchange apparatus has the following problems. First, this automatic record exchanging apparatus changes the rotation angle of the magazine and the loading / reproducing mechanism in accordance with the storage section of the selected record, so that the load on the moving mechanism for transferring the record to the loading / reproducing mechanism is reduced. Variations occur.
That is, for example, when transferring the records stored in the uppermost storage section of the magazine to the loading / reproducing mechanism, the storage plane is aligned with the storage plane in order to align the storage plane of the magazine with the loading plane of the record of the loading / reproducing mechanism. The surface formed by the loading plane becomes steep, and the load on the moving mechanism increases. On the other hand, when transferring the records stored in the storage section at the middle position of the magazine to the loading / reproducing mechanism, the surface formed by the storage plane and the loading plane becomes a horizontal plane, and the load on the moving mechanism is reduced. Therefore, the moving mechanism for transferring the records from the magazine to the loading / reproducing mechanism has to be designed so that the motor serving as the driving source thereof is adapted to the largest load, resulting in an increase in size. Was hindered.

Further, in this record exchanging apparatus, since the magazine is swiveled around the first axis, the records stored in the magazine may rattle and damage the records. Further, in this record exchange device, since the magazine is pivoted around the first axis, when the magazine is tilted to the loading / reproducing mechanism, records other than the record to be transferred to the loading / reproducing mechanism do not fall from the magazine. It is necessary to provide a holding mechanism as described above, and the configuration of the magazine becomes complicated and large.

Further, in this record exchanging apparatus, when the number of records stored in the magazine is increased, it is necessary to increase the interval between the record / reproduction mechanism and the recording / reproducing mechanism.
The whole device is enlarged.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a disk exchange device capable of reducing the size of the entire device and simplifying its structure.

[0008]
