[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading mechanism for an optical disk drive device.

[0002]

2. Description of the Related Art An optical disk drive apparatus, which is an apparatus for recording / reproducing information on / from an optical disk recording medium, is generally installed horizontally with the optical disk recording medium installed parallel to the installation surface. In some cases, it may be convenient to install vertically installed vertically to the surface, and conventionally, there are optical disk drive devices for both horizontal installation and vertical installation.

A conventional optical disk drive device will be described with reference to the drawings. FIG. 7 is an overall perspective view of a conventional optical disk drive device.

In the figure, α is an optical disk drive device, D
Reference numerals a and Db are optical disc recording media, 1 is a housing, 1a is a front opening, 2 is a loading tray, 2a is a first disc storage recess, 2b is a second disc storage recess, and 2c is a claw-shaped member.

The optical disk drive device α shown in FIG.
Case 1 and front opening 1a formed in the case 1
And the optical disc recording medium D is placed on the front opening 1
A guide rail 1 is provided between the front surface of the housing 1 and the inside of the housing 1 via a.
It is composed of a loading tray 2 movable along b and a loading mechanism (not shown) for driving the loading tray 2.

On the upper surface of the loading tray 2, there is provided a first disc accommodating recess 2a for mounting an optical disc recording medium Da having a large diameter, and a diameter of the first disc accommodating recess 2a is provided at the center thereof. A second disc storage recess 2b for mounting a small optical disc recording medium Db is provided.

At least a part of the left side portion of the first disc storage recess 2a is projected from the left side portion of the first disc storage recess 2a toward the center of the loading tray 2 or is stored therein. A selectable claw-shaped member 2c is formed on.

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. 7 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 disk support member 2c is housed therein. Next, the user uses the housing 1
From the upper side, the optical disk recording medium Da or Db is placed in the first disk storage recess 2a or the second disk storage recess 2b.

Then, a loading mechanism (not shown) is operated to retract the loading tray 2 into the housing 1 along the guide rails 1b and house it, and a spindle motor (not shown) is rotationally driven to drive the optical disk recording media Da, Db.
Read the recorded information of.

When the optical disk drive device α is used in a vertical installation, the left side surface of the housing 1 is installed on the installation surface side,
Pull out the claw-shaped member 2c. Next, the user mounts the optical disk recording medium Da from the right side of the housing 1 between the first disk housing recess 2a and the claw-shaped member 2c. Alternatively, once the optical disk recording medium Db is mounted in the center hole Aa of the disk adapter A, they are integrally mounted from the right side of the housing 1 between the first disk storage recess 2a and the claw-shaped member 2c. To do.

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 disc storage recess 2a and the disc support member 2c, it is held in the approximate center of the loading tray 2 so as not to fall off. At the time of ejecting, the procedure opposite to the loading operation is performed.

[0013]

However, the conventional optical disk drive device α has the following drawbacks when installed vertically. Since the optical disc recording media Da and Db are structured to be supported between the first disc storage recess 2a or the second disc storage recess 2b formed in the upper surface of the loading tray 2 and the claw-shaped member 2c, Had the problem of.

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, there is a drawback that the disk adapter A must be prepared and the work is complicated.

Secondly, since the disk support member 2c 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 cannot be installed on the installation surface side. However, there was a drawback that the degree of freedom of installation posture was low.

Thirdly, when the optical disc recording medium D is placed between the first disc housing recess 2a and the disc supporting member 2c, the recording / reproducing surface of the optical disc recording medium D contacts the surface of the loading tray 2. However, there is a drawback that the recording / reproducing surface is easily damaged.

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