A turntable 3 on which the media Da and Db are rotatably mounted, a spindle motor 4 provided inside the housing 1 for rotationally driving the turntable 3, and an optical disk recording provided inside the housing 1. An optical pickup P for reading recorded information by moving the media Da and Db close to each other in the radial direction.

On the upper surface of the loading tray 2 shown in FIG. 4, there is provided a first disc accommodating concave portion 2a for accommodating an optical disc recording medium Da having a large diameter. A second disc storage recess 2b for mounting an optical disc recording medium Db having a small diameter is provided in the recess.

Further, in the central portion of the loading tray 2, the optical pickup moving hole 2 which is an escape area for the moving range of the optical pickup P when the loading tray 2 is stored.
c is pierced.

Further, penetrating holes 2 are penetratingly provided at two places on the left side around the first disk accommodating recess 2a, and the penetrating hole 2d is formed in the penetrating hole 2d.
A claw-shaped movable member 5 that can selectively select either a pulled-out state or a stored state toward the center of the loading tray 2 is fitted.

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. 3 is pulled out to the attachment / detachment exchange position will be described.

When the optical disk drive device α is installed horizontally, the bottom surface of the housing 1 is installed on the installation surface side and the claw-shaped movable member 5 is housed therein. Next, the user mounts the optical disk recording medium Da or Db from the upper side of the housing 1 on the first disk storage recess 2a or the second disk storage recess 2b.

Next, a loading mechanism (not shown) is operated to pull the loading tray 2 into the housing 1 along the guide rails 1b and house it. The loading tray 2 is placed on the turntable 3 and the spindle motor 4 is driven to rotate. The pickup P is moved to read the record information on the optical disc recording media Da and Db.

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 and the claw-shaped movable member 5 is pulled out. Next, the user uses the housing 1
From the right side surface, the optical disk recording medium Da is placed between the first disk storage recess 2a and the claw-shaped movable member 5.

Alternatively, after the optical disk recording medium Db is once mounted in the center hole Aa of the disk adapter A, the optical disk recording medium Db and the optical disk recording medium Db are integrally mounted from the right side surface of the housing 1 into the first disk housing recess 2
It is placed between a and the claw-shaped movable member 5.

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 media Da and Db are
Since it is supported between the first disk storage recess 2a and the claw-shaped movable member 5, it is held so as not to fall off in the approximate center of the loading tray 2.

Then, a loading mechanism (not shown) is operated, the loading tray 2 is drawn along the guide rails 1b into the housing 1 and housed, and the loading tray 2 is placed on the turntable 3 to rotationally drive the spindle motor 4 to drive the light. The pickup P is moved to read the record information on the optical disc recording media Da and Db. Also, the optical disc recording media Da, Db
The eject operation is performed in the reverse order of the loading operation.

[0016]

However, the conventional optical disk drive device α has the following drawbacks when installed vertically. The conventional loading tray 2 is provided with a claw-shaped movable member 5, and the optical disk recording media Da and Db are provided with a first disk storage recess 2a or a second disk storage recess 2b recessed in the upper surface of the loading tray 2. Since the structure is supported between the claw-shaped movable member 5 and the claw-shaped movable member 5, it has the following problems.

First, when the optical disc recording medium Db having a small diameter is to be 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.

Second, since the claw-shaped movable member 5 is provided only on one side of the loading tray 2, when the housing 1 is installed vertically, the right side of the housing 1 can be installed on the installation surface side. In addition, there is a drawback that the degree of freedom of the installation posture is low.

Thirdly, when the optical disk recording media Da and Db are placed between the first disk housing recess 2a and the claw-shaped movable member 5, the recording / reproducing surfaces of the optical disk recording media Da and Db are loaded on the loading tray. 2 There was a drawback that the recording and reproducing surface was easily damaged by contact with the surface.

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

[0021]

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. A tray, a turntable provided in the center of the upper surface of the loading tray for pivotally supporting a center hole of the optical disk recording medium in a detachable and rotatable manner; and a turntable provided under the turntable of the loading tray. The optical disk drive device includes a spindle motor that is rotationally driven.
