The present invention relates to an optical disc drive device, and more particularly, to an optical disc drive including a compact disc ROM drive for a computer or a disc drive for an audio / video compact disc player. More specifically, it relates to an optical disc drive with a disc anchor installed in the tray.

The compact disc ROM drive is an auxiliary storage device of a computer, and is usually used in a computer main body. In addition to the main components, monitors and keyboards, which are the most essential components, computers include a variety of input / output devices and peripherals, and when used in an office or home, the space occupied by them increases inconvenience. Recently, there have been attempts to modify the exterior design of the computer to increase the consumer's desire to purchase.

A typical example of the modification of the exterior of a personal computer is a case in which the computer body is vertically deformed. In the early days of the popularization of personal computers, most computer makers allowed the computer body to be used horizontally, but this method had a problem that a large area was allocated when the computer was placed on a desk. This problem has been attempted to be solved by the appearance of so-called tower computers. That is, the position of the floppy disk driver and the position of the driver built in the computer main body are changed so that the computer main body can be used vertically instead of horizontally. However, the recent rapid increase in the size of a compact disc ROM drive has to be kept horizontal when installed in a computer or other peripherals. This means that when a compact disc is to be used in the drive, the disc must be moved to the drive position as a transfer device after the disc is placed in the tray, and the drive cannot be installed vertically because there is no device for fixing the disc in the tray.

This point can be seen more clearly in the first (a) and (b). FIG. 1 (a) is a plan view of a compact disc ROM drive according to the prior art, and FIG. 1 (b) is a side view of (a) and shows a state where the disc tray protrudes outward. When inserting the disk, the user places the disk 12 on the plane of the tray 11 in the state shown in the figure. The disc 12 is conveyed to the drive position by the disc loading device. The disk 12 is rotated by the spindle motor 13 in the driving position, and data stored in the disk 12 is read by the optical pickup device 14 which moves in a linear direction along the guide rail 15. do.

In such a disk drive, the disk is rotatably fixed when the disk is driven on the turntable, but there is no fixing device when the tray protrudes out of the drive, so the drive cannot be installed vertically on the computer. This was the same cause of limitations in the disc drivers used in optical disc players for audio / video.

SUMMARY OF THE INVENTION An object of the present invention is to provide an optical disk drive device provided with a roller fixing means for fixing a disk so that the disk can be used in a tray.

In order to achieve the above object, according to the present invention, there is provided a tray capable of arranging an optical disk thereon, a driving means for rotationally driving the optical disk, and an optical pickup means capable of reading information stored in the optical disk. An optical disk drive apparatus comprising: at least one roller fixing means including elastic members along a circumferential surface of the tray in which the disk is disposed so as to detachably fix the disk disposed in the tray of the optical disk drive There is provided an optical disk drive device characterized in that one.

According to another feature of the invention, the elastic member has a horizontal portion and the inclined portion, the horizontal portion is fixed by the fastening means with respect to the tray, the end of the inclined portion extending from one or both ends of the horizontal portion is roller Support rotatably.

According to another feature of the invention, three roller fixing means are arranged on the tray at intervals of 120 degrees along the circumferential surface on which the disk is to be arranged.

Hereinafter, the present invention will be described in more detail with reference to a preferred embodiment shown in the drawings.

2 is a side cross-sectional view of the tray 28 in which the roller fixing means 21 according to the present invention is installed, and in FIG. 3 a perspective view of the roller fixing means is shown. The roller fixing means 21 comprises a leaf spring and a roller 23. The leaf spring can be divided into a horizontal portion 24 and the inclined portion 25, the horizontal portion 24 is fixed to the tray 28 through a screw or the like. In the tray 28 shown in the figure, the plane of the tray 28 forms a step so that the two disks 22, 22 'having different diameters can be fixed. A small diameter disk 22 'may be disposed on the plane of the tray 28 having a low step height, and a large diameter disk 22 may be disposed on a tray 28 having a high step height. The horizontal portion 24 of the leaf spring is fixed with a screw 26 to the lower surface of the tray 28 on which the large disk 22 is disposed. The inclined portion 25 is formed on both sides of the horizontal portion 24, and the roller 23 is rotatably installed at the end of the inclined portion 25. The outer circumferential surface of the roller 23 provided on the inclined portion 25 of the leaf spring toward the center of the tray 28 is closer toward the center of the tray 28 than the outer circumferential surfaces of the disks 22, 22 ′. Thus, once the disks 22, 22 'are disposed on the plane of the tray 28, the roller 23 elastically presses the outer circumferential surfaces of the disks 22, 22'. Since the roller 23 provided on the inclined portion 25 of the plate spreading has an elastic rotational motion with the inclined portion 25 as the radius of rotation when an external force is applied, the roller 23 is pressed by the disks 22 and 22 'by hand. Can be fixed from the bottom, or lifted out of the roller 23 by lifting the disks 22 and 22 '. This is the same when the disks 22 and 22 'are rotationally driven on the turntable, and are fixed to or separated from the roller 23 by the mechanical force applied to the disks 22 and 22'. In the disc drive which handles only the disk of the same diameter, the inclination part 25 may be formed only in one end, and only one roller 23 may be provided. The roller 23 is rotatable about the rotation shaft 27, and the rotation shaft 27 is welded to the inclined portion 25 of the leaf spring. Unlike the above, the inclined portion 25 of the leaf spring may be rolled up so as to form a bearing for the rotation shaft 27 of the roller 23 by itself, thereby fixing the rotation shaft 27 of the roller 23. . It is preferable that the roller 23 does not scratch the surface of the disks 22 and 22 'when fixing the disks 22 and 22' using a material such as synthetic resin or rubber. The elastic force of the leaf springs allows the disks 22 and 22 'to easily disengage from the roller 23 when the disks 22 and 22' are fixed on the tray 28 or when the disks 22 and 22 'are rotationally driven. It is desirable that it be as much as possible. The user grasps the disks 22 and 22 'by hand and places them on the tray 28. The elastic force of the leaf spring applied by the fixing device roller 23 is the force of pressing the disks 22 and 22' by hand. It must be overcome. When the disks 22 and 22 'contact the bottom surface of the tray 28, the roller 23 is restored to its original position to fix the disks 22 and 22' to the tray 28. The disks 22, 22 'are fixed on the tray 28 and move into the drive and are placed on top of the turntable, where the tray 28 is in a direction perpendicular to the plane on which the disks 22, 22' are arranged. By moving a predetermined distance, the disks 22 and 22 'are disengaged from the roller 23. (In contrast, the turntable with the disks 22 and 22' disposed thereon is perpendicular to the plane of the tray 28.) The discs 22 and 22 'may be disengaged from the roller 23 by moving a predetermined distance with each other.) The information reading operation of the discs 22 and 22' is finished and the discs 22 and 22 'are externally moved. The operation of the tray 28 proceeds in the reverse order when unloading. That is, the tray 28 moves toward the plane of the disks 22 and 22 ', and the force exerted on the fixing roller 23 by the disks 22 and 22' overcomes the elastic force of the leaf spring. (22, 22 ') is fixed to the roller (23) fixing device arranged in the tray (28).

FIG. 4 shows the arrangement of the roller fixing means 21 in the tray 28 in FIG. At least one roller fixing means 21 is preferably arranged in the tray 28 along the circumferential surface on which the disks 22 and 22 'are to be arranged. In the illustrated embodiment, three rollers are provided at intervals of 120 degrees. .

The use of the roller fixing means according to the invention has the advantage that the arrangement of the optical disc drive can be freed. That is, in the past, the optical disk drive should be used only by keeping it horizontal, but by using the roller fixing means, the optical disk drive can be positioned in any direction with respect to a computer or other peripheral device or audio device. Incidentally, there is an advantage that the consumer's desire to purchase can be enhanced by freely modifying the exterior of the computer main body or peripheral device in which the ROM drive is embedded.

Although the present invention has been described with reference to the preferred embodiment shown in the drawings, those skilled in the art will understand that various embodiments are possible from this. Therefore, the true scope of protection of the present invention should be determined by the appended claims.
