The present invention relates to a loading / unloading device of a disc player, and more particularly, to a loading / unloading device of a disc player to prevent members installed on the deck plate from being impacted when the deck is loaded.

Disc players are devices for reproducing information recorded on discs such as compact discs, CD-ROMs, and digital video discs. The disc player has a deck for loading the disc when the disc is loaded into the carriage and drawn into the housing. The deck consists of a deck base on which one side is rotatably fixed and the other side is lifted and lowered by a hinge axis, and a deck plate fastened to the deck base and provided with a turntable and an optical pickup. When the deck base performs a loading / unloading operation, a means for suppressing vibration is required so that the optical pickup is not impacted.

1 is a schematic exploded perspective view showing a conventional loading / unloading device of a disc player.

The loading / unloading device of the disc player has a deck base 10 and a deck plate 20 as shown.

The deck base 10 is hinged to one side of the housing (not shown), the other side is raised and lowered by the driving means (not shown).

The deck plate 20 is located above the deck base 10, and the center portion 22 of the deck plate 20 is open. The deck plate 20 is provided with a turntable 26 for rotating the inserted disc and an optical pickup 28 for reproducing the information recorded on the disc. Each of the deck base 10 and the deck plate 20 has a plurality of fastening grooves 12 and 24 formed therein. The fastening grooves 12 and 24 are formed at positions facing each other, and by positioning the washer 35 between the two fastening grooves 12 and 24 and fastening by using the screw 31, the two members are mutually coupled. do.

The shock absorbing member 33 is fitted into the fastening groove 24 of the deck plate 20 to prevent the deck plate 20 from being impacted when the deck base 10 is loaded / unloaded. The shock absorbing member 33 is a member capable of absorbing vibration such as rubber, and the center portion thereof is opened so that the screw 31 can be fitted.

The loading / unloading device of the disc player made as described above has a disadvantage in that the shock absorbing member is formed only at a predetermined position of the deck plate 20 and the deck base 10 so as not to effectively absorb the vibration generated.

Accordingly, an object of the present invention is to provide a disc player loading / unloading apparatus capable of effectively alleviating vibration of an optical pickup during loading / unloading.

In order to achieve the above object, a disc player loading / unloading apparatus according to the present invention,

A deck base having a hinge axis and a side wall formed with a lifting guide protrusion, a deck plate positioned on an upper surface of the deck base and having an open center at which a turntable and an optical pickup can be installed, and the deck base and the deck plate are fastened. In the loading / unloading apparatus of a disc player provided with a buffer means for alleviating the vibration generated when the deck base is raised and lowered,

A flange portion formed on the side wall of the deck base by the buffer means; A buffer plate configured to open a central portion and to have a first coupling portion coupled to the flange portion, and a second coupling portion coupled to an upper surface of the deck plate to mitigate vibration transmission; First fastening means for coupling the first coupling portion and the flange portion; Second fastening means for coupling the second coupling part and the deck plate; Characterized in that provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 and 3 are schematic exploded perspective views and front views respectively shown for explaining the loading / unloading apparatus of the disc player according to the present invention. 4 is a cross-sectional view taken along the line A-A of FIG. 3, and FIG. 5 is a cross-sectional view taken along the line B-B of FIG.

As shown, the loading / unloading apparatus of the present invention is roughly divided into a deck base 40, a deck plate 50 and a cushioning means.

The deck base 40 has a side wall 41 formed at its edge. The side wall 41 is formed with a hinge shaft 45 rotatably coupled to a housing (not shown) of the disc player, and a guide protrusion (not shown) which is moved up and down in conjunction with a carriage (not shown) for transporting the disc. It is. Thus, the deck base 40 is raised and lowered on the other side with respect to one side that is rotatably fixed.

The deck plate 50 is located on the upper surface of the deck base 40, and the center portion 51 is opened so that the turntable 59 and the optical pickup 57 can be installed. The deck plate 50 is moved up and down in accordance with the movement of the deck base 40, the turntable 59 is in close contact with or separated from the center of rotation of the inserted disk.

The buffer means is a means for fastening the deck base 40 and the deck plate 50 and mitigating the vibration generated by the rotation of the turntable so that the optical pickup 57 does not malfunction.

The buffer means includes a flange portion 43 formed on the side wall 41 of the deck base 40, a buffer plate 60, the first fastening means for coupling the buffer plate 60 and the flange portion 43, It consists of a second fastening means for coupling the buffer plate 60 and the deck plate (50).

The buffer plate 60 is an integral member having a central portion 61 opened therein, and a first coupling portion 65 fastened on the flange portion 43 and a second coupling portion fastened on the deck plate 50. It consists of (63). The buffer plate 60 is made of a material capable of absorbing vibration, for example, a hard rubber plate to mitigate transmission of the vibration generated when the deck base 40 is raised and lowered to the deck plate 50.

The first fastening means includes a plurality of first through holes 71 formed in the first coupling part 65, a plurality of first fastening grooves 47 formed in the flange 43, and a plurality of screws 73. ) The first through hole 71 and the first fastening groove 47 are formed at positions corresponding to each other, and are fastened by the screw 73 to couple the buffer plate 60 to the flange portion 43.

The second fastening means includes a plurality of second fastening grooves 69 formed on the second coupling part 63, a plurality of coupling protrusions 53 formed on an upper surface of the deck plate 50, and the second coupling means. It consists of a plurality of support angles (67) formed on the bottom of the portion (63), and a plurality of second through holes (55) formed on the deck plate (50). Each of the second fastening grooves 69 and the coupling protrusions 53 are positioned to face each other, and the coupling protrusions 53 are cocked to the second fastening grooves 69. The support angle 67 passes through the second through hole 55 and supports the deck plate 50 and the buffer plate 60 to maintain a predetermined height with respect to the bottom surface of the deck base 40. The support angle 67 may be integrally formed with the buffer plate 60 to elastically support the deck plate 50 with respect to the deck base 40.

Since the loading / unloading device of the disc player provided as described above combines the deck base and the deck plate using a buffer plate, the buffer area can be formed wide, thereby effectively alleviating vibration generated during loading / unloading.
