And a loading mechanism (not shown) provided in the housing 1 for driving the loading tray 2, and the optical disk recording in the housing 1 accommodated in the loading tray 2. A turntable (not shown) on which the media Da and Db are rotatably mounted, a spindle motor (not shown) provided inside the housing 1 to rotate and drive the turntable, and the optical disk provided inside the housing 1 It is composed of an optical pickup (not shown) for moving the recording media Da and Db close to each other in the radial direction to read the recorded information.

On the upper surface of the loading tray 2 shown in FIG. 5, there is provided a disc storage recess 2a for mounting an optical disc recording medium Da having a large diameter, and further, in the center of the disc storage recess 2a, a disc A disc housing recess 2b for mounting a small optical disc recording medium Db is provided.

Further, an optical pickup moving hole 2c is provided in the center of the loading tray 2 and serves as an escape area for an unillustrated optical pickup moving range when the loading tray 2 is stored.

Further, locking protrusions 2d are provided at two places on the left side around the disk storage recess 2a so as to protrude toward the center of the loading tray 2.

The operation of such a conventional optical disk drive device α will be described. The operation from the state where the loading tray 2 shown in FIG. 5 is pulled out to the attachment / detachment exchange position will be described.

When the optical disk drive device α is used in a horizontal installation, the bottom surface of the housing 1 is installed on the installation surface side.
Next, the user selects the optical disc recording medium Da from the upper side of the housing 1.
Alternatively, Db is placed in the disc storage recess 2a or 2b of the disc storage recess 2, respectively.

Then, a loading mechanism (not shown) is operated, the loading tray 2 is pulled into the housing 1 along the guide rails 1b and accommodated, and the loading tray 2 is placed on a turntable to rotationally drive the spindle motor to drive the optical pickup. The recording information on the optical disk recording media Da and Db is read by moving.

When the optical disk drive device α is installed vertically, the left side surface of the housing 1 is installed as the installation surface side. Next, the user mounts the optical disc recording medium Da having a large diameter from the right side surface of the housing 1 between the disc housing recess 2a and the locking protrusion 2d.

Alternatively, once the optical disc recording medium Db having a small diameter is mounted in the center hole Aa of the disc adapter A, the disc housing recess 2a and the locking projection 2d are integrally formed from the right side of the housing 1. Place between and.

Then, a loading mechanism (not shown) is operated to draw the loading tray 2 into the housing 1 and store it. At this time, the optical disc recording medium Da or the optical disc recording medium Db mounted on the disc adapter A is
Since it is supported between the disk storage recess 2a or 2b and the locking projection 2d, it is held in the approximate center of the loading tray 2 so as not to fall off.

Then, a loading mechanism (not shown) is operated to retract the loading tray 2 into the housing 1 along the guide rails 1b and store it, and the loading tray 2 is placed on a turntable to rotationally drive the spindle motor to drive the optical pickup. The recording information on the optical disk recording media Da and Db is read by moving. The ejecting operation of the optical disk recording media Da and Db is performed in the reverse procedure of the loading operation.

Since the structure is supported between a or 2b and the locking projection 2d, it has the following problems.

First, when an optical disc recording medium Db having a small diameter is placed, the optical disc recording medium Db is once attached to the disc adapter A and then the loading tray 2 is loaded.
However, the disk adapter A must be prepared in advance, and the work is complicated.

Secondly, when the optical disk recording media Da and Db are placed between the disk housing recess 2a and the locking projection 2d, the recording / reproducing surface of the optical disk recording media Da and Db is brought to the surface of the loading tray 2. There is a drawback that the recording / reproducing surface is easily damaged due to contact.

Here, the present invention provides an optical disk drive device which has a high degree of freedom in installation posture and does not require a separate adapter member when the optical disk recording medium is mounted.

[0020]

In order to solve the above-mentioned problems, the present invention adopts the following novel concrete solving means. That is, a feature of the present invention is that a housing having a front opening is formed, and an optical disk recording medium is placed on the top surface, and the loading inside the housing and the front surface of the housing is movable via the front opening. An optical disk drive device comprising: a tray; and a movable disk clamper that is movable on the loading tray in the radial direction of the optical disk recording medium and rotatably holds a part of a circumferential portion of the optical disk recording medium.
