The optical pickup device 22 is linearly moved by the action of being rotated by the power of the feeding motor 28 while the pinion 26 is engaged. At this time, the auxiliary gear 30 meshing with the rack gear 24 is installed on the deck plate 18 at the position where the outer end of the rack gear 24 on the optical pickup device 22 reaches in the stop mode. The auxiliary rack gear 34 having a predetermined length is integrally formed on the bottom surface of the tray 32 corresponding to the installation position of the auxiliary gear 30, and the feeding motor 28 is formed on one side of the upper surface of the deck plate 18. The tray transfer gear 36 which is rotated in place by receiving power transmitted from the optical pickup device 22 to the optical pickup device 22 is installed.

On the other hand, between the tray 32 and the deck plate 18 described above, as shown in FIG. 3, the optical disk is turned on the turn table 14 when the tray 32 is located at the center of the turn table 14. There is provided an optical disk lifting means for smoothly seating and separating.

Such an optical disk lifting means substantially includes the characteristic elements of the present invention, and is roughly divided into a guide boss 2, a rotation lever 3, a lifting rod 4, and an inclined pressure rail 5.

The guide boss 2 extends on both lower surfaces of the lower side of the tray 32, and the guide hole 2a communicates with guide long holes 33 formed on both sides of the tray 32.

The pivoting lever 3 is supported by guide pins 33 formed on both sides of the tray 32 (only one side in the drawing) so as to be rotatably supported by the pins, and one side thereof is a guide boss ( It is located inside the guide hole 2a of 2), and the other side thereof protrudes toward the upper portion of the tray 32 to be in contact with the optical disk mounted on the tray 32.

And on one side of the rotation lever 3, that is, one side located inside the guide hole 2a of the guide boss 2, the long hole 3a is formed in a predetermined length along the longitudinal direction.

The lifting bar 4 is installed so as to be moved up and down from the inner side of the guide hole 2a of the guide boss 2, the upper one side of the rotating lever 3 described above by the moving pin (6). It is slidably connected to the long hole (3a) of, the lower portion is formed in a spherical shape.

On the other hand, the above-mentioned inclined pressure rail (5) is for selectively transporting the lifting bar (4) up and down, is formed on the upper surface of both sides of the deck plate 18, the turn table (14) is located, Figure 4 As shown in FIG. 3, the inner side of the tray 32 is gradually inclined toward the inner direction based on the conveying direction (arrow direction) of the tray 32.

At this time, the above-mentioned rotation lever (3) can be returned to the initial position by the weight of itself and in particular the weight of the lifting rod (4), but through the torsion spring (S) for a quick initial position return It is provided to elastically bias in the direction opposite to the pressing direction by the steel bar 4, ie upwards.

Reference numeral 32a is a cutout groove formed in the rear center side of the tray 32.

Referring to the operating state of the present invention configured as described above are as follows.

First, when the optical disk (D) is initially seated on the tray 32, the optical disk (D) on the upper surface of the rotating lever (3), one end of which protrudes above the tray 32 by the torsion spring (S) ) Is mounted so that the optical disk D is kept spaced apart from the upper surface of the tray 32 by a predetermined distance. Therefore, interference with the turn table 14 positioned on the deck plate 18 is excluded in the process of sliding the tray 32 by the feeding motor 28.

On the other hand, in the state where the tray 32 is slidingly conveyed to some extent, that is, when the center of the optical disk D seated on the pivoting lever 3 and the turn table 14 coincide, the guide boss 2 The elevating rod 4 located on the guide hole 2a of the elbow is pressurized upward by the inclined pressure rail 5 formed on the deck plate 18, and at the same time the moving pin 6 of the elevating rod 4 By being slid along the long hole 3a of the pivoting lever 3, the pivoting lever 3 is pivoted about the portion supported by the pins on the tray 32. As shown in FIG.

Accordingly, as shown by the virtual line in FIG. 3, the rotation levers 3 rotate inwardly corresponding to each other, and at the same time, the optical disk D placed on the upper surface of the rotation levers 3 descends to turn table ( 14) to be seated on the phase.

On the contrary, when the optical disk D is to be taken out, the lifting bar 4 pressurized by the inclined pressure rail 5 is pulled downward by the tray 32 being taken out to the front by the feeding motor 28. As the pivoting lever 3 is returned to the initial position by the torsion spring S at the same time, the optical disk D is lifted by the pivoting lever 3 as shown by the solid line in FIG.

Therefore, interference between the turn table 14 and the optical disk D is eliminated, and the optical disk can be easily taken out from the turn table.

As described above, according to the optical disc player according to the present invention, not only the feeding of the tray and the pick-up device can be carried out simultaneously through one feeding motor, but also the optical disc on the turntable during the tray feeding process. Therefore, it is possible to smoothly settle out and separate take out, there is no need for a separate tilting means has the advantage of reducing the cost and workability.
