Abstract

PURPOSE: A disk player is provided to fix a disk, and write and read the disk after a case is fixed, and move the disk jack out of the disk player while releasing the case after the disk is released. CONSTITUTION: If a disk jack(1) is input into a disk player, a holder(5) is pushed into the disk player, so that the holder fixes the disk jack by stopping elements. If the holder and an upper holder fixing plate(6) move following a guide part(3) in the case that the disk jack moves in and out, a cover is opened by a projection formed at the guide part. A protrusion(7) formed at the upper holder fixing plate ascends or descends following a groove formed at a guide plate(8) for preventing the disk jack from separating. The protrusion is inserted into a recognizing hole installed at the disk jack, acting as a cover spring buffer.

Description

Disc player {DISC PLAYER}

The present invention relates to a disc player, and more particularly, to a disc player using a disc jack including a CD pack, a disc pack, or a dual disc.

Conventionally, various media, such as a compact disc player, a floppy diskette player, and a digital video disc player, are used as media reproducing means.

However, currently used disks, unlike floppy diskette players, have no protective jacket and thus are not protected from external damage or intrusion of foreign matter such as dust. Accordingly, a technique related to a disc jack for protecting a disc media such as a compact disc or a laser disc is disclosed in Korean Patent Application No. 10-2001-0039867 filed by the applicant of the present invention.

It is a first object of the present invention to provide a disc player that reads data by playing a disc jack.

A second object of the present invention is to provide a disc player in which, in addition to the first object, the step of inserting and ejecting and fixing the disc is manually or automatically operated.

In order to achieve the above object, the present invention is configured by connecting the fixing of the case with the upper and lower fixing of the disk to enable the insertion and withdrawal of the disk jack even in the absence of power in the manual player. In addition, in the automatic player, the disc is fixed while the disc jack is pushed down to the spin motor and the sensor so that the disc jack is pushed down to the spin motor and the sensor so as to enable continuous operation in the insertion, withdrawal, and disc fixing using a motor. And a structure in which the disk is fixed as the spin motor is raised.

Hereinafter, a preferred embodiment of a disc player according to the present invention will be described in detail with reference to the accompanying drawings, FIGS.

1A to 1C are views showing the holder mounting state before the holder of the disc jack is inserted along the guide portion in the disc player according to the present invention. Referring to FIG. 1A, when the holder 5 and the fixing plate 6 move along the guide part 3 when the disc jack 1 is taken out and inserted, an apparatus for opening the cover is installed.

That is, according to the preferred embodiment of the present invention, in the case of horizontal mounting (Figs. 2 and 5), the cover is opened by the jaw in the holder guide portion 3, and in the case of vertical mounting (Figs. 3 and 4), the holder is opened. Install the device that opens the cover with the guide part down.

Further, as a recognition hole to be installed in the disc jack, the upper holder along the groove in the guide plate 8 is slid in by installing the projection 7 fitted in the write protection hole or the type recognition hole to the holder upper fixing plate 6. The fixed plate 6 comes down, so that it does not easily come out of the disc jack player even when it is not inserted, and the cover spring cushioning function at the time of withdrawal.

Figures 2a and 2b is a view showing a state in which the fixed disk and the case of the manual horizontally mounted player according to the present invention. Referring to FIG. 2B, when the holder 5 is pushed in while the disc jack 1 is inserted, two stop devices 13 and 14 operate simultaneously to fix the disc.

The operation is performed at the same time as in the 3.5-inch floppy disk driver, and when the ejection is connected to each other and the ejection button is pressed, the disc retainer stop 14 is released and the case fixer stop 13 Is released. The dual device shown in Fig. 2B is because the thickness of the disk jack is thicker than that of the floppy diskette.

3A and 3B show an embodiment of a passive vertically mounted player according to the present invention. Referring to FIG. 3A, when the disc jack is mounted to the holder 5, the stop device 25 at the rear of the guide portion fixes the holder.

4A and 4B show an automatic vertically mounted player according to the present invention. Referring to FIG. 4A, when the transfer rack gear 35 is operated by the input / output motor installed in the guide part 3 and the holder 5 is completed to enter the guide part, the vertical movement driving motor is operated to rotate the rotary slider ( 32), push the chuck and guide part down.

At this time, the cover opening plate 33 which comes down together may also maintain the state where the feeding is completed. Referring to FIG. 4B, a wedge-type slider is moved to the left and right instead of the rotary slider, and the disk can be stably fixed by using two or more sliders.

5 is a view showing an automatic horizontally mounted disk player according to the present invention. Referring to Fig. 5A, the disk jack is fixed to the holder 5 to fix the disk at the same time up and down. At this time, the holder stop plate 44 of the moving plate 41 for spin motors to be lifted fixes the holder.

In addition, the moving plate 41 is moved upward by the wedge-shaped slider 37 as shown in FIG. 4B, but upward movement is caused by the spring 47 and the connecting arm 46 guide plate 43 as shown in FIG. 5B. Switched to the lower motion, the chuck moving plate 42 comes down to fix the disk.

On the other hand, when the disc jack is pulled out, the wedge-type slider is pulled out and the lower moving plate 41 and the guide plate 43 on which the spin motor is fixed are lowered, and the center groove is fixed up and down while the guide groove 49 is lowered. Both ends of the two connecting arms 46 with the rotating shaft protrusion 48 move down.

In addition, the middle part engaged with it rises up and stops at that position by a spring. At this time, if the vertical movement distance is large, the spring 47 may be used even if a rack and a gear are used instead of the slider.

Fig. 5C is a view showing the reference moving rod 50 moving left and right, which can perform the feeding-out operation and the disk vertical fixing operation with one motor according to the present invention. Referring to Fig. 5C, the lower part of the rod is a drive motor connecting gear 51, and the upper part is provided with a transfer rack gear 52 and a slider gear 53.

As a preferred embodiment of the present invention, the gears are fixedly rotated and the rod 50 is moved so that the loading and unloading and the disk locking and unlocking occur sequentially.

The foregoing has outlined rather broadly the features and technical advantages of the present invention to better understand the claims of the invention which will be described later. Additional features and advantages that make up the claims of the present invention will be described below. It should be appreciated by those skilled in the art that the conception and specific embodiments of the invention disclosed may be readily used as a basis for designing or modifying other structures for carrying out similar purposes to the invention.

In addition, the inventive concepts and embodiments disclosed herein may be used by those skilled in the art as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. In addition, such modifications or altered equivalent structures by those skilled in the art may be variously changed, substituted, and changed without departing from the spirit or scope of the invention described in the claims.

As described above, the present invention provides a device in which the disc jack is released from the player while the disc is fixed and the recording and playback is performed, and the disc is released after the disc is released. do.

As a result, in the case of a manual disc player, the case fixing and the disc releasing operation are linked to each other so that the disc is released first and the case is released later. In addition, in the case of the automatic disc player, if the input is made by the motor after the case is fixed, the disc is fixed by vertical movement.
