DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magazine for mounting a disk in a changer type disk reproducing apparatus which can be stored in a plurality of disk devices.

[0002]

2. Description of the Related Art Conventionally, in the field of car audio,
There are roughly two types of changer-type disc reproducing devices capable of reproducing a plurality of discs. One type is called a magazine type changer. A so-called magazine capable of storing a plurality of disks is mounted inside the changer, and the selected disk is pulled out of the magazine and moved to a playback position to play the disk. Is performed.

[0003] This magazine is intended to protect discs that are easily handled roughly in automobiles.
When not attached to the changer, it also functions as a disk storage. In addition, by preparing a plurality of magazines each storing a disk, it is possible to replace a plurality of disks at the same time by replacing the magazine.

However, in a magazine type changer, it is necessary to secure a space for a magazine to be mounted in the changer, and the changer is inevitably increased in size.

On the other hand, there has been proposed a so-called slot-in type changer in which a slit is provided in the front panel for inserting and removing a disk, and the disk is loaded into a disk storage portion disposed inside the changer through the slit.

[0006]

However, contrary to the magazine type changer, if the disk not stored in the changer is not stored in the disk case or a required storage, the disk is damaged. There is fear. Further, when all the discs stored in the changer are to be replaced, the user is required to remove the discs one by one and insert the discs one by one. Each type changer has advantages and disadvantages.

[0007]

According to the present invention, in order to solve the above-mentioned problems, a plurality of discs concentrically housed therein are simultaneously moved and mounted in a changer-type disc reproducing apparatus. A disk withdrawing means for engaging a plurality of disks, and a coupling means for coupling the changer-type disk reproducing means and the disk withdrawing means to drive the disk withdrawing means by a driving source provided in the changer-type disk reproducing apparatus. Is provided.
