Then, a substantially circular recess 3 is formed on the upper surface of the disc tray 2 to form a CD or a CD-R.
After the disc 4 for recording and / or reproducing such as OM is inserted into the recess 3 and placed horizontally on the disc mounting surface 3a, as shown in FIG. The apparatus main body 1 is configured to be horizontally loaded from the direction of arrow a.

At this time, as shown in FIGS. 12 and 13,
A notch 5 is formed from the center of the recess 3 of the disc tray 2 to the end in the loading direction (direction of arrow a), and the disc table 6 integrated with the spindle motor and the disc table 6 are formed above and below the disc device main body 1. An optical pickup 7 and a disc clamper 8 are arranged, and the disc table 6 and the disc clamper 8 constitute a chucking means CM. In addition, a truncated cone-shaped centering projection 6a is integrally formed in the upper center of the disk table 6, and a tapered surface 6b is formed on the outer periphery of the projection 6a.

As shown in FIG. 12, when the disc tray 2 is ejected outside the disc device body 1 in the direction of arrow b, the disc table 6 and the optical pickup 7 in the disc device body 1 and the disc clamper 8 are provided. And are retracted by a pair of upper and lower support frames 9 and 10 about the fulcrum shafts 11 and 12 in the up and down directions of the disc tray 2 in the directions of arrows c and d.

Then, as shown in FIG. 13, when the disc tray 2 is completely loaded in the disc device main body 1 in the direction of the arrow a, a pair of upper and lower support frames 9 and 1 are provided.
0 is simultaneously driven to rotate about the fulcrum shafts 11 and 12 in the directions of arrows e and f. And the notch 5 of the disc tray 2
The disc table 6 and the optical pickup 7 are inserted from below in the direction of arrow e, and the disc table 6 is inserted into the center hole 4 of the disc 4 by the centering projection 6a.

[0007]

By the way, in the conventional disc apparatus of this type, as shown in FIGS. 9 and 10A, the disc 4 is mounted on the disc mounting surface 3a of the recess 3 of the disc tray 2. It is a dedicated horizontal use machine that is placed horizontally and loaded, and is not suitable for vertical use in which the disc device body 1 is installed vertically along with the disc tray 2.

That is, as shown in FIG. 10 (B), when the disc tray 2 is used while standing vertically with the disc device main body 1, the recess 3 becomes vertical, so that the disc 4 is placed vertically in the recess 3. However, there is a problem that the disc 4 cannot be placed on the disc tray 2 because the disc 4 slides down in the direction of the arrow g due to its own weight at the tapered surface 3b portion of the outer periphery of the recess 3 even if it is intended to be placed on the disc tray 2.

On the other hand, in particular, in the CD-ROM drive industry, there is an increasing demand for vertical use of the disk device for the purpose of installing the disk device in a narrow space as the computer becomes smaller.

The present invention has been made to meet the above-mentioned demands, and an object of the present invention is to enable one disk device to be used both horizontally and vertically while ensuring high safety. I am trying.
