[0020] The disk data reading device of the present invention includes a disk tray 100 and an upper cover 200 . Such as image 3 As shown in the cross-sectional view, the disk tray 100 has a groove 120 for placing a disk 140 . The groove 120 has a groove leading edge 122 . For this embodiment, the disc tray 100 is made of plastic, however, in other embodiments, it can be made of sheet metal, polymer, glass, and other materials that can provide similar functions.

[0021] Such as figure 2 As shown, the upper cover 200 includes an upper panel 220 parallel to the disc tray 100 . For this embodiment, the upper panel 220 is made of sheet metal, however, in other embodiments, it can also be made of plastic, polymer, glass, and other materials that can provide similar functions. The upper panel 220 includes a blocking portion 300 and a plurality of bending boundaries, and the blocking portion 300 is formed by bending the upper panel 220 from one of the plurality of bending bounda...

[0031] see Figure 5A , Figure 5A It is a cross-sectional view of the second embodiment of the disk data reading device of the present invention. The main difference between the second embodiment and the first embodiment is that the second part 420 extends downward from the front edge of the upper panel 220 to the bending boundary 320, and the third part 430 turns from the bending boundary 320 to the opposite direction of the panel 700. Extends to the groove leading edge 122 . For a preferred embodiment, the second portion 420 is perpendicular to the upper panel 220 , and the second portion 420 is perpendicular to the third portion 430 at the same time. However, the second portion 420 is not limited to be perpendicular to the upper panel 220 and the third portion 430 respectively, and other angles are also possible.

[0032] Such as Figure 5AAs shown, the blocking portion 600 is mainly composed of the third portion 430 . A slit 500 is formed between the third portion 43...

[0034] Figure 5B Shown is a cross-sectional view of a third embodiment of the present invention. The main difference between the second embodiment and the first embodiment is that the blocking portion 600 is only composed of the second portion 420 . In addition, the second portion 420 does not extend downward from the front edge of the upper panel 220 , but extends downward from the upper panel 220 between the front edge 122 of the groove and the front edge 240 of the upper cover. According to the embodiment, the second part 420 is a planar structure. However, in other embodiments, the second portion 420 can also be a block structure, a mesh structure, and other structures that can provide similar functions.

[0035] Such as Figure 5B As shown, the second portion 420 is perpendicular to the disc tray 100 . When the disk 140 is broken in the disk reading device, the second portion 420 is used to directly block the cracked disk fragments generated after the rupture, so as ...

Abstract

The present invention provides an optical disk data fetch device, including tray on which the optical disk can be placed and upper cover, the upper cover includes upper face plate which is parallel to disk tray and has barrier portion and several bent edges. When the optical disk is broken in the interior of fetch device, the barrier portion can prevent the broken disk pieces from being ejected from the interior of fetch device. Besides, the barrier portion also can increase the strength of said upper cover.

Description

technical field [0001] The invention relates to a disc data reading device, which is used to prevent the cracked disc fragments produced by disc rupture from shooting out. Background technique [0002] As the multiples of optical drives continue to increase, and the quality of optical discs on the market is uneven, incidents of discs breaking and flying out when the optical drive is running are common. Therefore how to prevent the cracked disc from flying out has become one of the key points in the design of the optical drive mechanism. [0003] Figure 1A and Figure 1B It is a schematic diagram and a cross-sectional view of a disc data reading device in the prior art. Generally speaking, the cracked optical disc usually passes through the gap between the disc tray 100 and the upper cover 200 first. Utilize powerful impact again to destroy the outer cover 720 on the panel 700, to shoot and hurt people. Traditionally, the front edge 240 of the upper cover is bent downwar...
