A carrier storage rack and an autochanger-type automatic carrier recording / reproducing apparatus which are configured to pick up a carrier placed on the disk driving means and store the carrier in the carrier storage rack via the carrier transport means described above are widely used. It is known.

FIGS. 4A and 4B are perspective views of a carrier storage rack and a carrier automatic recording / reproducing apparatus (hereinafter, referred to as an autochanger) 1 as previously proposed by the present applicant. In a carrier storage rack (hereinafter, referred to as a disk storage rack) 3a in which a plurality of carriers (hereinafter, referred to as disks) such as optical disks such as CDs are stored between a plurality of partition plates 11a, 11b #, a disk 2 is provided. Storage rack 3a for storing or removing
A rail 12 is laid on the lower front side of the opening, and the disk transport means 4 is pivotally mounted along the length of the rail 12 so as to be slidable.

[0004] A disk loader 15 constituting carrier guide means is rotatably mounted on the disk transport means 4 described above. This disk loader 15 has a disk 2
And the disk 2 can be mounted on the turntable 20 of the disk drive means 5. The disk 2 mounted on the turntable 20 is clamped on the disk drive means 5 arranged on the chassis 10. To a playback or recording state.

The above-mentioned disk storage rack 3a is mounted on the front plate 1
The plurality of partition plates 11 described above between 1F and the rear plate 11B.
a, 11b are formed, and these front plates 11F and 11B
Are provided with through holes 11Fa and 11Ba.

In order to take out the disk storage rack 3a from the housing 19 of the autochanger 1, the front plate 11
When the handle 16 fixed to F is pulled out in the direction of arrow A, for example, the carrier drop prevention shaft 17 housed inside the side surface of the housing 19 is taken out and the through hole 11Fa of the front plate 11F is taken out.
After inserting the discs into the center holes 2a of the plurality of discs 2 placed between the partition plates 11a and 11b and the through holes 11Ba of the rear plate 11B to fix the plurality of discs, the disc storage rack 3a is moved forward of the housing 19. The drawer and the plurality of disks 2 are configured not to fall off the partition plates 11a and 11b.

The operation of the above-configured autochanger is as follows. First, the disk transport means 4 is moved along the rail 12 to the position of the designated disk 2 stored in the disk storage rack 3a. The disk transport means 4 is rotated by the disk loader 15 which is rotated so as to be parallel (vertical direction) and is in a vertical state as shown in FIG. 4A.
The designated disk 2 is taken in via the digit part 4a of the.

Next, in order to play the designated disk 2,
For example, the disk transport means 4 including the disk loader 15 is moved in a predetermined direction along the rail 12 to the empty drive means 5 side, and the disk loader is brought on the turntable 20 of the disk drive means 5. The disc 2 is placed on the turntable 20 by tilting the disc loader 15 toward the disc driving means 5 so that the center hole 2a of the disc 2 is inserted into the inclined portion provided on the turntable 20, and then the disc loader 15 is transported to the disc. The means 4 is reversely rotated to the vertical portion side and returned to the original position. Thereafter, the disk 2 is clamped to be in a reproduction or recording state.

After the disk 2 has been reproduced or recorded, the outer periphery of the disk 2 is gripped by a guide roller provided on the disk loader 15 in the reverse operation, and the disk loader 15 is rotated clockwise to move vertically. After the state, the disk transport means 4 is moved along the rail 12 in the longitudinal direction of the rail 12, brought to a predetermined position of the disk storage rack 3a, and the guide rollers are released to move the disk 2 to the predetermined storage position. It is made to store.

[0010]
