Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading tray for an optical disk drive. 2. Description of the Related Art An optical disk drive, which is a device for recording and reproducing information on an optical disk recording medium, is generally employed in a horizontal installation in which an optical disk recording medium is installed in parallel with an installation surface. In some cases, it is convenient to install the medium vertically and vertically on the installation surface, and there has conventionally been an optical disk drive device that can be used both horizontally and vertically. A conventional optical disk drive will be described with reference to the drawings. FIG. 5 is an overall perspective view of a conventional optical disk drive. In the figure, α is an optical disk drive, A is a disk adapter, Da and Db are optical disk recording media,

Guide the front of the housing 1 and the inside of the housing 1 through the guide rail 1b
, A loading mechanism (not shown) provided inside the housing 1 for driving the loading tray 2, and the optical disk recording provided in the housing 1 and housed 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 for rotating the turntable; and the optical disk provided inside the housing 1 An optical pickup (not shown) for reading the recorded information by moving the recording media Da and Db close in the radial direction. [0006] On the upper surface of the loading tray 2 shown in FIG. 5, a disk storage recess 2a for mounting an optical disk recording medium Da having a large diameter is recessed. A disk storage recess 2b on which a small optical disk recording medium Db is placed is recessed. In the center of the loading tray 2, there is formed an optical pickup moving hole 2c, which is an escape portion for an optical pickup moving range (not shown) 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 project 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 α is used in a horizontal installation, the bottom surface of the housing 1 is installed on the installation surface side.
Next, the user operates the optical disk recording medium Da from the upper side of the housing 1.
Alternatively, Db is placed on the disk storage recess 2a or 2b of the disk storage recess 2 respectively. Next, a loading mechanism (not shown) is operated, the loading tray 2 is drawn into the housing 1 along the guide rail 1b, housed, placed on a turntable, and rotationally driven by a spindle motor to drive the optical pickup. It moves and reads the recorded information on the optical disk recording media Da and Db. When the optical disk drive device α is used in a vertical installation, the left side of the housing 1 is installed as an installation surface. Next, the user places the large-diameter optical disc recording medium Da between the disc storage recess 2a and the locking projection 2d from the right side of the housing 1. Alternatively, after the optical disk recording medium Db having a small diameter is once mounted in the center hole Aa of the disk adapter A, these are integrally integrated from the right side of the housing 1 into the disk storage recess 2a and the locking projection 2d. Place between. Next, a loading mechanism (not shown) is operated, and the loading tray 2 is pulled into the housing 1 and stored. At this time, the optical disk recording medium Da or the optical disk recording medium Db attached to the disk adapter A is
Since the loading tray 2 is supported between the disc storage recesses 2a or 2b and the locking projections 2d, the loading tray 2 is held so as not to fall off substantially at the center. Next, a loading mechanism (not shown) is operated, and the loading tray 2 is drawn into the housing 1 along the guide rail 1b, stored therein, placed on a turntable, and rotationally driven by a spindle motor to drive the optical pickup. It moves and reads the recorded information on the optical disk recording media Da and Db. The ejection operation of the optical disk recording media Da and Db is performed in a procedure reverse to that of the loading operation. However, the loading tray 2 of the conventional optical disk drive device α is
Has the following drawbacks when installed vertically. The loading tray 2 of the conventional example has a locking projection 2d, and the optical disk recording media Da and Db are provided with a disk storage recess 2 recessed on the upper surface of the loading tray 2.
Since it is a structure supported between a or 2b and the locking convex piece 2d, it has the following problems. First, when the optical disk recording medium Db having a small diameter is to be placed, the optical disk recording medium Db is once mounted on the disk adapter A, and then loaded onto the loading tray 2.
The disk adapter A must be prepared in advance, and the operation is complicated. Second, when the optical disk recording media Da and Db are placed between the disk accommodating concave portion 2a and the locking convex piece 2d, the recording / reproducing surfaces of the optical disk recording media Da and Db move to the surface of the loading tray 2. There is a disadvantage that the recording and reproduction 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 an additional adapter member when mounting an optical disk recording medium. In order to solve the above problems, the present invention employs the following new specific solutions. That is, a feature of the present invention is that a housing having an opening formed on a front surface thereof, and an optical disk recording medium is placed on the upper surface, and the inside of the housing and the front surface of the housing are movable via the front opening. a tray, the upper surface the loading tray
