The present invention relates to a tray of an optical disk changer having an optical disk seating presence display function, and more particularly, to an optical disk seating to a roulette which accommodates at least one or more optical disks so that a selected optical disk is seated on a turntable and played. The present invention relates to a tray of an optical disc changer having an optical disc seating presence display function, which enables the user to easily check the naked eye without rotating the roulette.

In general, an optical disc player records a digital signal in the form of irregularities on a disc, and then projects a light having high condensing power, such as a laser beam, onto the surface of the disc, receives the reflected light, and reproduces the recorded signal according to the difference in the amount of light. It is an electronic device.

The disc changer includes a disc changer for taking out and recording / reproducing selected discs from a magazine accommodating a plurality of discs coaxially, and rotating the roulette from a roulette for accommodating a plurality of discs in the same plane. There is a disc changer that records / plays discs.

In the latter disc changer, when the disc accommodated in the roulette is selected and recorded / reproduced and then exchanged with another disc, recording / playback is stopped and the roulette is rotated to be exchanged with another disc for recording / playback. In this manner, after the recording / reproduction of all the discs stored in the roulette is completed, the roulette can be taken out from the main body so that the disc can be replaced.

And, as shown in Figure 1, when explaining the tray structure of the optical disk changer according to the prior art, the turntable (3) for rotating the optical disk seated on the first desk (2) mounted inside the housing (1) An optical disk rotatably mounted by driving of a spindle motor (not shown), in which an optical pickup 6 including an objective lens 5 is seated on the turntable 3 in a second deck 4 mounted on the first deck 2. A plurality of seating surfaces 7 installed so as to slidably move in a radial direction of the first optical disk, which are moved in the front-back direction and the vertical direction by a driving means with respect to the housing 1 described above, and the first optical disk having a different size on the upper surface is selectively received. The tray 8 of predetermined shape formed by this concentric circle is provided.

The light beam is irradiated to the above-described seating surface 7 through the objective lens 5 and through the turntable 3 to be recorded / reproduced.

However, in order to check whether or not the optical disks A and B accommodated in the seating surfaces 10 and 11 of the roulette 12 are driven, the driving means 13 provided on the bottom surface of the tray 8 is driven. Accordingly, the roulette 12 is rotated in the forward and reverse directions so that the roulette 12 is positioned at the correct position of the tray 8, so that the roulette 12 can be confirmed whether or not the optical disks A and B are seated.

Therefore, when the user checks whether the optical disk is seated in the roulette 12 accommodating at least one optical disk, it is inconvenient for use because it is possible to rotate the roulette 12 by driving the driving means. The increase in electric charges due to the driving means.

Accordingly, it is an object of the present invention to visually identify a user without having to rotate the roulette with or without the mounting of the optical disk to the roulette which accommodates the at least one optical disk so that the optical disk selected by the user is seated on the turntable and played. It is to provide a tray of an optical disk changer equipped with an optical disk seating presence display function to provide convenience.

The above object of the present invention is a tray of an optical disc changer in which a roulette for accommodating at least one or more optical discs seated on a turntable mounted on a deck is rotatably mounted in a reverse direction with respect to a tray, wherein the tray predetermined position is provided. It is achieved by providing a tray of the optical disc changer equipped with an optical disc seating presence display, characterized in that it comprises a see-through section for visually identifying the seating of the optical disc accommodated in the roulette.

According to a preferred feature of the present invention, a see-through hole of a predetermined shape is formed in the tray as the see-through part.

Hereinafter, a preferred embodiment of the present invention will be described in detail according to the accompanying drawings.

FIG. 2 is a plan view of the tray being opened in the optical disc changer to which the tray according to the present invention is applied, and FIG. 3 is a schematic cross sectional view taken along line A-A of FIG.

As shown in the figure, a first deck 2 is installed inside the housing 1 and a turntable 3 for rotating an optical disk seated thereon is mounted on the first deck 2 and mounted on the turntable 3. A second deck 4 on which the optical pickup 6 including the objective lens 5 sliding in the radial direction of the optical disk to be seated is installed, and moved forward and backward and up and down with respect to the housing 1, A tray 8 having a seating surface 7 in which an optical disk is accommodated is formed in a concentric manner, and at least one or more second optical disks having a diameter smaller than that of the first optical disk described above, being rotatably mounted on the bottom surface of the tray 8. The configuration of the roulette 12 having a predetermined shape in which the seating surfaces 10 and 11 are accommodated is the same as the conventional configuration shown in FIG. 1, and thus descriptions of the configuration and operation thereof will be omitted. The same reference numerals for the same members shown in FIG. It was marked.

Therefore, a preferred embodiment of the present invention is a predetermined shape that can visually confirm the presence or absence of the second optical disk seating accommodated in the seating surface 10 (11) of the roulette 12 described above at the predetermined position of the tray (8). To form a perspective hole (14) (15), the perspective hole (14) (15) may be formed of an elliptical long hole or polygonal, circular, etc., the size and position of the perspective hole (14) (15) is roulette It is formed differently according to the specification of the optical disk changer so that the label of the second optical disk seated on the seating surface (1) (11) of (12) can be confirmed.

Referring to the operation of the present invention as described above, as shown in FIG. 2 and FIG. 3, the tray 8 opened / closed by the front-rear driving means with respect to the housing 1 is opened, and then the tray 8 The optical disks (A) and (B) are respectively seated on the seating surfaces 10 and 11 of the roulette 12 by rotating the roulette 12 by driving the driving means 13 of the roulette 12 mounted on the bottom surface. The tray 8 is closed to the housing 1 by its forward and backward driving means, and the optical disk A received in one seating surface 10 of the roulette 12 is located above the turntable 3, and the tray ( Since it descends by the driving means in the up-down direction of 8) and is seated on the turntable 3, recording / reproducing of the optical disc A is possible.

On the other hand, since the optical disk B seated on the seating surface 10, 11 of the roulette 12 is covered by the tray 8, the user rests through the see-through hole 15 formed at a predetermined position of the tray 8. It is possible to visually check whether the optical disk B is seated on the surface 11 easily.

Therefore, when receiving the optical disk (A) (B) in the seating surface (10) (11) of the roulette 12, or when checking whether the mounting, or the optical disk accommodated in one seating surface 10 of the roulette (8) When (A) is located in the correct position of the tray 8, when the presence or absence of mounting of the optical disk (B) accommodated in the other seating surface 12 of the roulette 12, the roulette mounted on the bottom surface of the tray (8) It is possible to check with the naked eye of the user without driving the driving means 13 of (12).

As described above, the tray of the optical disc changer provided with the optical disc seating presence display according to the present invention can be visually confirmed by the naked eye whether the optical disc is seated in the roulette for accommodating at least one or more optical discs and is convenient for the user. It provides the characteristics and saves the electric charges due to the use of the drive motor that rotates the roulette when checking whether the optical disk is seated.
