Description

Disk guide device for a disc player {A apparatus for guiding a disk}

The present invention relates to a disc guide device of a disc player for guiding a disc inserted into a disc player body and loaded into a clamping position in the disc player body. In particular, the disc guide device prevents the disc from tilting when the disc is loaded, The present invention relates to a disc guide device for a disc player, which is improved to prevent the player from being miniaturized.

A disc player generally includes a turntable on which a disc loaded into the disc player body is placed, a clamp for clamping the disc with the turntable while being in close proximity to the turntable, and for rotating the disc clamped by the turntable and the clamp. And a spindle motor and an optical pickup for irradiating a light beam on the disk to read information from the disk rotated by the spindle motor.

Such a disc player is a type in which a disc is inserted by a tray installed in and out of the main body according to a method of inserting the disc, and the disc player directly inserts the disc through the disc entrance provided in the main body without providing the tray as described above. Can be distinguished in form.

The trayless disc player includes a loading device for loading a disc inserted through a disc entrance into a clamping position, and a disc guide device for guiding both edge portions of the disc loaded by the loading device.

As such a guide device, a guide rail supporting a disc is provided in the disc player main body while slidingly contacting the bottom surface of both edge portions of the disc loaded in the clamping position. The reason why the guide rail is slidably contacted only at the bottom of both edges of the disc is that the loaded disc can be lifted by the turntable and clamped by the turntable and clamp so that the disc is loaded with the disc. This is to allow upward movement.

However, when the guide device of the conventional configuration described above is adopted, the disk may be moved up and down while being loaded. In this case, not only noise is generated but also the disk does not take the correct posture at the loading position. There is a problem that it is not done correctly.

Disc guide device for this is disclosed in Korean Patent No. 0252125, shown in Figures 1 and 2. The disclosed technique has a pair of guide members 22 for guiding the disk 1 inserted into the disc player body and loaded into the clamping position. The pair of guide members 22 is for guiding the movement of the disk during the loading of the disk 1, with each guide member 22 moving together with the slider 60 in a direction perpendicular to the disk insertion direction. It is supported by the cover 20 as much as possible.

Guide slots 222 are formed in the guide members 22 in the disc insertion direction so that both edge portions of the loaded disc 1 can be fitted.

As shown in FIG. 1, the guide device 22 is guided between the clamp 21 and the turntable 13 by inserting both edge portions of the disc 1 so that the guide members 22 approach each other while loading the disc, as shown in FIG. 1. Since the guide members 22 are configured to be spaced apart from each other and the interference with the disk 1 can be released after the loading is completed as shown in FIG. 2, the disk is prevented from flowing up and down during loading of the disk. Noise and clamping defects caused by the up and down flow of the disk during the loading of the disk are suppressed.

However, in the guide device as described above, the guide member 22 having the guide slot 222 for guiding the disk 1 is installed in the space between the clamp 21 and the turntable 13, and is disposed on the upper surface of the cover 20. By providing the slider 60, it is disadvantageous in downsizing the player.

That is, since the thickness of the player is increased by the guide member 22 and the slider 60, it is disadvantageous for thinning the player, that is, miniaturization.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a disk guide device for an improved disk player, which is advantageous for thinning the disk player and stably guides the disk.
