【Example】

 As shown in FIGS. 1, 2, and 3, the present invention has one lid 10, a central circular hole 11 is provided at the center of the surface of the lid 10, and one central hole 11 is provided on one side of the surface. Two fan-shaped openings 12 are provided, one arc-shaped slide groove 13 is provided on the surface opposite to the fan-shaped openings 12, and a projecting wall 14 having an appropriate height is provided around the lid 10. A portion of the projecting wall 14 corresponding to the fan-shaped opening 12 is cut out to form a notch, and an upper end of the projecting wall 14 is bent inward to form a horizontal plane 141 having an appropriate width. A cut line 1411 is provided near both ends adjacent to the notch.

The present invention further comprises a circular shield piece 20, a central circular hole 21 symmetrical to the central circular hole 11 of the lid 10 is provided in the center thereof, and a central circular hole 21 is provided on one side of the surface thereof. A fan-shaped opening 22 is provided, and a U-shaped cut is made at a position opposite to the fan-shaped opening 12 on the surface, and the inside of the cut is bent downward to form one projecting piece 23. When the lid 20 is placed on the lid 10, the protruding piece 23 projects to the bottom surface of the lid 10 and is slidable along the arcuate slide groove 13, so that the shielding piece 20 is placed on the surface of the lid 10. The fan-shaped openings 12, 22 overlap each other or are separated from each other so that the fan-shaped openings 12 of the lid 10 are opened and closed.

After the shielding piece 20 and the lid body 10 are combined, the upper side of the shielding piece 20 is covered with one wipe paper 30, and the CD 40 is fitted from the notch portion of the projecting wall 14 of the lid body 10 and further. The surface of the CD 40 is covered with one layer of the protective film 50, and thus the effect of protecting the CD 40 is achieved.

At the time of use, simply slide the protrusion 23 to expose a part of the CD 40 through the overlapping fan-shaped openings 12 and 22, and then set the CD 40 together with the protective cover 1 of the present invention in the CD drive 60. The reading can be advanced to the CD drive 60 through the fan-shaped opening.

As shown in FIG. 4, after the shielding piece 20 of the present invention and the lid 10 are assembled, the CD 40 is fitted from the notch of the protruding wall 14 of the lid 10. At this time, the CD 40 Due to the notch line 1411 in the horizontal plane 141 of 14, the projecting wall 14 can be expanded outwardly when the CD 40 is fitted, so that the CD 40 is smoothly fitted into the protective cover 1.

Please refer to FIG. 5, 6 and FIG. 1 in combination. When the present invention is used, the projecting piece 23 is slid to expose the fan-shaped opening 12 of the lid body 10, thereby exposing the CD 40 from the fan-shaped opening 12, and further the whole protective case 1 with the lid body 10 down. Then, the slide sheet 601 is placed horizontally on the slide sheet 601 of the CD drive 60, and the slide sheet 601 is slid into the CD drive 60. Then, the rotary shaft 602 installed in the CD drive 60 is inserted into the central circular hole of the CD 40 and rotated with it, and the optical device 603 reads the data recorded in the CD 40 through the opening 12 of the lid 10. In this way, the present invention eliminates the need to directly remove the CD40 by hand as is well known in the whole operation process, and also prevents the CD from being scratched due to a collision when it is set in the CD drive, thus achieving a reliable protection effect. ing.

As shown in FIG. 7, when the protective cover 1 accommodating the CD of the present invention is set in the CD drive 60, the rotating shaft 602 of the CD drive 60 is immediately inserted into the central circular hole of the CD 40 and the CD 40. Then, the optical device 603 reads the data stored in the CD 40 directly from the fan-shaped opening 12 of the lid body. The bottom of the lid 10 is in contact with the slide sheet 601 of the CD drive 60. By providing an appropriate number of the slip pads 15 on the bottom of the lid 10 at symmetrical positions, a more reliable slip effect can be obtained. The lid 10 and the shielding piece 20 obtained can be prevented from rotating together with the CD 40.
