Reference numeral 8 is a turntable, 9 is a spindle motor, and 10 is a mechanical unit.

In the conventional optical disk drive apparatus α shown in FIGS. 9 to 12, a disk housing recess 6a1 having a diameter slightly smaller than the outer diameter of the optical disk recording medium D1 is provided on the front surface of a box-shaped housing 1. And a front opening for horizontally loading and unloading the loading tray 6 in which a disk storage recess 6a2 having a diameter smaller than the outer diameter of the disk recording medium D2 is recessed from the upper surface of the disk storage recess 6a1. A front panel 1a having an opening formed in the portion 1b is provided.

Inside the housing 1, the loading tray 6 is provided.
An unillustrated loading mechanism for horizontally driving the front surface of the housing 1 and the inside of the housing 1 through the front opening 1b so that the housing 1 can be housed therein, and the optical disk recording media D1 and D2.
Turntable 8 that fits into the center hole Da of the
An optical pickup P for recording and reproducing information recorded on the optical disc recording media D1 and D2, and a turntable 8 rotatably supported by a pivot 10a inside the housing 1.
A mechanical unit 10 for moving up and down the optical pickup P and the optical pickup P as a unit, and a chucking pulley 3 for rotatably sandwiching the center hole Da of the optical disc recording media D1, D2 between the upper surface of the turntable 8 and the mechanical unit 10. It is composed of a clamper plate (not shown) that suspends and pivots the chucking pulley 3 from above in the housing 1 so as to be rotatable. The clamper plate includes a first disk storage recess 6a1 and a second disk storage recess 6a2. In either case, the optical disc recording media D1, D
The holding function of 2 is not particularly provided.

The operation of the optical disk drive device α will be described. First, a loading mechanism (not shown) is driven to pull out the loading tray 6 to the front surface of the housing 1 through the front opening 1b of the front panel 1a.

Then, the optical disc recording medium D1 having a large diameter is placed on the first disc storage recess 6a1 provided in the upper surface of the loading tray 6, and the optical disc recording medium D2 having a small diameter is placed on the upper surface of the loading tray 6. After being simply placed from the recess 6a1 onto the second disk storage recess 6a2 further recessed, the loading mechanism (not shown) is driven to pull the loading tray 6 into the housing 1.

[0011]

However, the conventional optical disk drive device α has the following drawbacks. That is, since the loading tray 6 itself does not have a function of holding the optical disc recording medium D, the optical disc recording media D1 and D2 are parallel to the installation surface, that is, in an oblique posture other than the so-called horizontal orientation or on the installation face. On the other hand, in a vertical orientation, in which the optical disc recording media D1 and D2 are dropped from the loading tray 6 and recording / reproduction becomes impossible, the optical disc recording media D1 and D2 cannot be ejected or are rotating. There is a drawback that the optical disc recording media D1 and D2 itself and the internal mechanism of the optical disc drive device α may be damaged due to the dropout of the optical disc recording media D1 and D2.

Here, an object of the present invention is to provide an optical disk drive device which can be installed in any posture.
