BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a kind of disc storage case with a self-locking security structure at the opening position. The case described herein can help protect the legal rights and interests of the disc issuers and enhancing the consumers&#39; ability in identifying the authorized discs, so as to prevent pilferage and distinguish originals from fakes. 
   2. Description of the Related Art 
   A disc storage case is usually composed of a case bottom, a case back, and case cover. The main function is for storing discs and protecting the disc from being damaged. Currently, most disc cases in the market do not have a security structure, thus it can be opened easily without damaging the case in any link of the distribution, and the disc may easily be subjected to theft and secret substitution. As a result, the issuers can hardly protect their legal rights and interests and the customers have difficulty in determining the genuineness of the discs, either. 
   SUMMARY OF THE INVENTION 
   The object of the present invention is to provide a kind of disc storage case with a security sign. When the case is opened for the first time, the sign will be damaged, so that the disc can&#39;t be stolen or changed by the lawbreakers during the course of distribution.

   DESCRIPTION OF THE INVENTION 
     FIG. 1  shows a typical embodiment of disc storage case of the present invention, including case cover  1 , case back  2 , and case bottom  3 , which are connected by the folding V-shaped trough  4 . In addition, a security board  5 , through which it can be judged whether the disc storage case is ever opened or not, is set at the outer side of the case cover  1 . 
   As shown in  FIG. 2 , security board  5  includes handle  7  that is connected to the outer side of the case cover  1  by the folding V-shaped trough  6  and locking board  9  that is connected to the handle  7  by the folding V-shaped trough  8 . An anti-withdrawal locking pin  10  is set on the locking board  9 . At the end of the handle  7  is the handle hole  21 . As shown in  FIG. 3 , at the end of the locking pin  10  is the arrow cone  22 , on the top of which is the flute  23 . As shown in  FIG. 1 , at the outer side of the case bottom  3  is the locking jack  11  corresponding to the locking pin  10 . The horizontal dimension of the arrow cone  22  is greater than that of the jack  11 . 
   As shown in  FIG. 1 , on both ends and outer side of case cover  1  is the vertical side  12 , which is vertical to the case cover  1 . On both ends as well as the outer side of the case bottom  3  is the vertical side  13  which is vertical to case bottom  3  and corresponds to the vertical side  12  of case cover  1 . The section of the vertical side  12  of case cover  1  corresponding to the security board  5  is the inward concave section  14 . On the vertical side  13  of the case bottom  3  is the concave section  15  corresponding to the concave section  14 . Locking jack  11  lies at the side near the bottom of the concave section  15 . The concave width of the concave section  15  of the case bottom  3  is slightly smaller than that of the concave section  14  of the case cover  1 , thus when case cover and case bottom are engaged, the concave section  15  of the case bottom lies outside, and the concave section  14  of the case cover lies inside. The purpose of setting concave sections  14  and  15  is that before the formal packing, the security board  5  and the locking pin  10  and some other structures which are located on the security board  5  can be received in the concave, so that the security board  5  can be turned to the position parallel to the vertical side  12 , and the packaging size of the storage case before formal packing can be reduced. Additionally, it can avoid the damage of the security board and error self-locking during the course of packaging and transportation of the empty cases. On the vertical side  12  are several raised bars  16  for orientation, and on the vertical side  13  are several flutes  17  corresponding to the raised bars  16 . When the case cover and bottom are engaged, the raised bars  16  penetrate into the flutes  17 , thus the case cover can be fixed. 
   As shown in  FIG. 1 , when case cover  1  and case bottom  3  are engaged, the vertical side  12  of the case cover  1  lies inside, and the vertical side  13  of the case bottom  3  lies outside. On the vertical side on the both ends of the case cover  1  is the flute  18  for positioning, and on the inner side of the vertical side on both ends of the case bottom  3  is the protruding slice  19  corresponding to the flute  18 . The height of the vertical side  12  of the case cover  1  is smaller than that of the vertical side  13  of the case bottom  3 . On the inner side of the vertical side of the case bottom  3  is the rigid supporting base  20  for bearing the case cover  1 . The central part  24  of the vertical side on both ends of the case cover  1  is of an arc protruding shape, which not only looks handsome, but also increases the strength of the central part of the case end. Thus the case cover can&#39;t be pried up from the middle part, and the disc won&#39;t be stolen or changed. 
   Resorting to the attached drawings, the using procedure of the disc storage case of the present invention is described as follows: 
   1. Put into the Disc and Encapsulate the Disc Storage Case 
   Firstly, open the disc storage case, lightly put the central hole of the disc to the disc supporting base  25  of the storage case as shown in  FIG. 1 , turn over the case cover  1 , then the case cover  1  and the conjoined security board  5  gradually shift towards the case bottom  3 . The arc heave  24  on both ends of the case cover  1  contacts the vertical side  13  at the end of the case bottom  3  and conducts radial guiding, when the positioning flute  18  on the case cover  1  touches the positioning protruding slice  19  on the case bottom  3 , the case cover  1  is to be axially positioned. When the axial positioning here is to be finished, with the case cover  1  shifted more, the vertical side at the outer side of the case cover  1  touches the supporting base  20  at the inner side of the outer section of the case bottom  3 . The case cover  1  is repositioned axially. When the case cover  1  and the case bottom  3  are closed completely, the protruding bar  16  on the case cover  1  joggles with the flute  17  on the inner side of the vertical side of the case bottom  3 , at which point the disc storage case is completely closed. Next, the security board  5  is turned back downwardly. The handle  7 , locking board  9 , and the locking pin  10  on it are shifted downwardly. When the arrow cone  22  on the top of the locking pin  10  reaches the locking jack  11  on the case bottom  3 , it enters the guiding positioning state before locking. At this time, the security board  5  is received outside the concave section of the case cover  1  and case bottom  3 . With the action of proper force, the locking jack  11  forces both limbs of the arrow cone  22  to deform towards the central flute  23 . The arrow cone  22  gradually penetrate into the locking jack  11 , then with the action of its own bounce, both limbs of the arrow cone  22  resume normal operations. It can&#39;t be withdrawn because it is blocked inside the locking jack  11 . Thus the disc is put in and the packing is also accomplished (Refer to  FIG. 4 ,  FIG. 5 , and FIG.  6 ). To guarantee that the locking pin  10  can insert into the locking jack  11  smoothly, the front of the locking jack  11  is designed into a bugle shape (Refer to FIG.  4 ). 
   2. Open the Disc Storage Case and Take out the Disc 
   After purchasing the well-packed disc, the user can lightly raise the end of the handle  7  of the security board  5  with a finger, and then put the finger into the handle hole  21 . Thus, the handle  7  can be torn along the V-shaped trough on both sides. Then the connection of the case cover  1  and the case bottom  3  at the position of the security board  5  is relieved, and the storage case is unlocked. The user can then open the case cover  1  and take out the disc in the case (Refer to  FIG. 7 ,  FIG. 8 , and FIG.  9 ). 
   When the handle  7  is torn when opening the case, the security board  5  is damaged, and the disc storage case can&#39;t resume the state before it is unlocked. Therefore, the consumers needn&#39;t worry that the disc inside is once changed if the packaging is complete. Additionally, it is very convenient to deposit or take out the disc after the security board  5  is torn. 
   To ensure that the handle  7  can be torn by hand successfully, appropriative unsealing tools can be prepared, such as special cutting tool. If for the causes of material or technique, the strength of the V-shaped groove on both sides of the handle  7  is not weak enough that the handle can be torn easily, the consumer can use the special cutting tool to cut the V-shaped trough, and then tear it.
