Disk Drive and Computer mounted with the Disk Driver}

The present invention relates to a disk drive capable of placing a disk vertically and a computer equipped with the disk drive. In particular, even if the small compact disk of 8cm in diameter to operate vertically, the small disk does not fall and relates to the disk drive to operate normally.

Hereinafter, a disk mounted in the disk driver according to the present invention will be described.

First, in terms of the shape of the disk, a compact disk, usually called a compact disk (CD), is mounted, and a circular shape is preferable in view of its rotation in operation.

Next, in view of the size of the disk, especially the diameter, compact disks have been developed in the past, only disks with a diameter of 12 cm, but disks with a diameter of 8 cm have been developed and commercially available. Therefore, there is a possibility that a compact disc having another diameter will appear in the future in consideration of ease of use with a computer and a user. In the present specification, a small disk refers to a disk having a diameter of 8 cm, and a large disk refers to a disk having a diameter of 12 cm. However, the disc drive according to the present invention can be applied to discs of new diameter that will emerge in the future.

Next, in terms of the types of discs, there are currently Compact Disc Read-Only Memory (CD-ROM), Compact Disc Rewritable (CD-RW), and Digital Versatile Disc (DVD). . Any type of disk can be applied to the disk driver according to the present invention as long as the shape and size described above are satisfied.

Hereinafter, a look at the prior art. Conventionally, there has been a disk drive in which the disk can be placed vertically.

1 is a plan view of a disk tray of a conventional disk driver. As shown, the disc drive includes a casing 10 and a disc tray 20. The disc tray 20 has a small disk seat 21 having a flat surface on which a small disk of 8 cm in diameter is placed, and a large disk seat 23 having a flat surface on which a large disk of 12 cm in diameter is placed. There are approximately four protrusions 25 at the edges of the flat surface of the large disc seating part 23, so that even if the large disc is placed vertically on the large disc seating part 23, it does not detach and operates normally.

However, in the case of the small disk seating portion 21, there is no separate device to prevent the small disk from being separated when the small disk is placed vertically, it is difficult to operate normally.

In this regard, a separate device for preventing the detachment of the small disk may be considered. Japanese Patent Application Laid-open No. Hei 10-199088 is one example. According to this, when the 8cm disk is placed vertically, the built-in holder is first projected manually, then the 8cm disk is placed, and then the projected holder is manually supported on the disk.

However, such a conventional small disk departure prevention device has the following problems. First, there is a hassle to protrude the built-in separation prevention device by manual operation. Second, it is difficult to stably support the rotating small disk.

Accordingly, it is an object of the present invention to provide a disc drive having a support member for protruding a built-in detachment preventing device automatically and stably supporting a rotating small disc.

As shown, the present invention includes a casing 100, a disc tray 200, and a support member 300.

The disk tray 200 includes a small disk seating unit 210 and a large disk seating unit 220.

The small disk seating portion 210 has a supporting plate 211 and a jaw 213.

The supporting plate 211 is a flat portion on which the small disk 1 is seated. The jaw 213 protrudes from the edge of the base plate 213 and prevents the seated disk 1 from being separated by centrifugal force. As shown in FIG. 6, an embodiment in which the support plate 211 is hinged with the first connecting portion 321 of the support member 300 is also possible. However, it is also possible to have a plurality of support plates 211. In this case, since the inner space is narrow, it is preferable to have two support plates 211 as shown in FIG. 3, and are integrally coupled without hinge coupling with the first connection portion 321 of the support member 300. It is also possible.

The large disc seating part 220 has a flat surface 221, a receiving groove 223, a protrusion 225, and a concave groove 227.

The flat surface 221 is where the large disk is directly placed. The receiving groove 223 is provided in the circumferential direction in a long hole shape on the flat surface 221. The long hole shape corresponds to the shape of the support 310 of the support member 300 accommodated in the receiving groove 223.

A plurality of protrusions 225 are provided at the edges of the flat surface 221 to prevent the large disks placed vertically from being separated. In order to prevent the detachment of a circular disk, three or more protrusions 225 may be provided.

The concave groove 227 has a substantially semi-circular shape that is large enough to accommodate a finger. It is preferable to have at least one concave groove 227 in order to easily take out the small disk 1 placed on the small disk mounting portion 210.

The support member 300 includes a support 310, a connection member 320, an elastic body 330, and a rotation support part 340.

The support 310 is automatically projected from the receiving groove 223 of the large disk seating portion 220 by pressing the small disk (1) on the support plate 211 and slightly. Since one side of the support 310 contacts the disk, it is preferable to have a round shape as shown in FIG. 5.

The connection member 320 has a first connection portion 321 and a second connection portion 323. The first connection part has a substantially straight rod shape and is coupled to the support plate 211 of the small disc seating part 210, and a predetermined portion is hinged to the rotation support part 340. Like the principle that the seesaw works, by using a light pressing force while placing the small disk 1 on the support plate 211 of the small disk seating portion 210, it is coupled to the second connecting portion 323 opposite The support 310 to protrude. The second connection portion 323 is a first extension portion 321 is bent and extended, the hinge is engaged with the support 310, and the protruding support 310 is rotatable. In addition, the second connection part has a shape in which one side coupled to the support 310 is bent to enable the support 310 to protrude.

Although the elastic body 330 is illustrated as a spring in FIG. 3, it is applicable to an elastic material capable of imparting an elastic force such as rubber. The position of the elastic body 330 may be mounted to the first connection portion, as shown. In this case, when the elastic body 330 pulls out the small disk 1 from the support plate 211 of the small disk seating part 210, the protruding support 310 again receives the receiving groove 223 of the large disk seating part 220. Pull the first connection portion 321 to return to.

On the other hand, the elastic body 330 is mounted on the second connecting portion, and when the small disk 1 is placed on the support plate 211 of the small disk seating portion 210, it is compressed, and when the small disk 1 is taken out, the compressed elastic body ( By using the 330 is restored by the elastic force it is also possible to return the protruding support 310 back to the receiving groove 223 of the large disk seating portion 220.

The rotation support part 340 includes a support shaft 341, a hinge pin receiving part 343, and a hinge pin 345.

The support shaft 341 is coupled to a predetermined position of the disc tray 200, and hinged to the connection member 320 using the hinge pin accommodation portion 343 and the hinge pin 345. The support shaft 341 allows the support plate 211 and the support 310 of the small disc seating portion 210 to perform the seesaw motion through the connecting member 320.

With this configuration, a process of implementing the support member 300 with the small disk 1 in the vertical position will be described with reference to FIGS. 3 to 5.

First, the small disk is held by hand and placed on the support plate 211 of the small disk seating portion 210. At this time, a finger may be inserted into a hole in the center of the small disk 1, or the finger may grasp the edge of the small disk 1 with a finger and rest on the support plate 211 using the recessed groove 227 on the large disk seating part 220. You can also

Next, the small disk 1 placed on the backing plate 211 is gently pressed with a finger. In this case, the pressed force moves the first connection portion 321 of the support member 300. The elastic body 330 connected to the first connector 321 is tensioned. Since the seesaw movement, the second connecting portion 323 opposite to the first connecting portion 321 moves in the opposite direction. As a result, the support 310 coupled to the second connector 323 protrudes from the receiving groove 223 of the large disc seating part 220.

Finally, the protruding support 310 is rotated approximately 90 degrees. Since the support 310 is hinged to the second connector 323, rotation is possible. And one side of the support 310 is in contact with the small disk (1). In this case, the small disk 1 vertically placed on the support plate 211 of the small disk seat 210 has a direction of the force applied by the support 310 and the force applied to the support plate 211 by the restoring force of the elastic body. On the contrary, since the support plate 211 and the support 310 are interconnected, the small disk 1 is provided with a disk driver which is prevented from detachment and operates stably.

As described above, according to the present invention, the detachment of the small vertical disk is prevented, thereby providing the effect that the disk driver can be stably operated.
