There must be three points. & The first difference is that the CD storage box 301 for 12cmCD and 12 holding pieces 391 are arranged at 30-degree intervals. In contrast, the CD storage box 3 8 2 for 8cmCD and the holding piece 3 9 1 3 10 arranged at 6 degree intervals. In addition, the number of the holding pieces is a general example, and is not limited to 12cmCD and 8cmCD. The second difference is that if the distance between the outer case 381 and the disc holding portion 309 (distance D in FIG. 15) is compared, the distance D of the CD storage case 302 for 8cmCD is more than the CD storage case for 12craCD. 301 are shorter. Third difference * The outer case 381 of the CD storage case 301 for 12 cmCD is mostly made of resin. In contrast, the CD storage case 302 for 8cinCD is mostly made of paper. Several types of devices have been proposed for detaching a CD stored in a CD storage case from a disc holding portion of the CD storage case. A representative example of such a conventional CD ejector is the "optical disc ejector" disclosed in Japanese New Patent No. 3018285 shown in Fig. 16. The state where the conventional CD ejector 401 is placed on the CD storage case 302 in Fig. 14 (B) is shown in Fig. 17.

Page 6 2000.12.18.006 4 4 8 4 2 -____ V. Description of the invention (3) The main body 410 is placed on the disc holding portion of the CD storage box, and the upper side of the pressing portion 411 can be pressed with a fingertip. . On the lower side of the pressing portion 411, a spring supporting portion 412 for receiving and fixing the base end portion of the spring 42 is provided. The spring supporting portion 412 can be used as a fulcrum to elastically deform the spring 420. Also, on the lower side of the pressing portion 411, A circumferential movement restricting portion 413 is provided, which is inserted into the slit of any one of the disc holding portions 3 09 and can be engaged with the retaining pieces 3 9 1 on both sides of the slit. On both sides of the circumferential direction movement restricting portion 41 3, protruding vertical movement restriction portions 414 are formed which can be engaged with the lower side of the retaining pieces 3 91 on both sides. The main body portion 410 having a complicated structure as described above is formed by integrally molding a resin. The spring 420 supported by the spring support portion 412 extends toward the upper surface side of the pressing portion via a slit provided in the pressing portion 411. A resin top plate 430 is attached to the front end of the spring "0. The spring 420 is configured to elastically change from the position shown by the solid line in Fig. 17 to the position shown by the dotted line." The disc holding portion 309 is fitted into the opening portion of the CD 10, and the state of holding the CD is shown by a dotted line. When the pressing portion 41 is pressed from this state, the holding piece 391 faces the disc holding portion. The direction of elastic deformation within 309 will weaken the force of holding the CD "by the disc holding portion 309. When the elastic force exerted by the spring 420 on the CD1G exceeds the force of the CDiO held by the disc holding portion 309, CD1 0 is lifted by the spring 420 through the top plate 43 and is lifted from the disc holding portion 309. Break away and reach the position shown by the solid line in the u-th figure.

4484 2 7 V. Description of the Invention (4) However, in the conventional CD ejector described above, the following problems occur. The detachment of the CD using the conventional CD detacher 401 is performed by applying a spring force by pressing a point on the lower side (information recording surface side) of the CD 10 using a single spring 120. However, it is not enough to apply a spring force to the CD with a single spring, and sometimes it is impossible to lift and lift the cymbal from the disc holding portion of the CD storage case. When the CD cannot be fully raised, it is difficult to capture the CD. Also, "the conventional CD remover 401 requires complicated work of assembling three components (main body, spring, and abutment surface), so there is a problem of poor productivity. Furthermore," the conventional CD remover 401 " In addition to the cost of manufacturing a plurality of components, there is a problem that it is difficult to reduce cost because assembly costs are still required. Furthermore, since the shape of the main body portion 410 is complicated, a mechanism for sliding the mold is required during the forming process, and there is a problem that the manufacturing is not simple. Furthermore, the conventional CD detacher 4001 is not provided with a member that prevents movement in a horizontal direction (e.g., the Η direction shown in Fig. 15). Therefore, there is a fear that the CD ejector 401 may move in the horizontal direction and may even fall off the CD storage case through the center hole of the disc holding portion 309. Furthermore, as the demand for CDs is rapidly increasing, in order to store more CD storage boxes in a small space, the demand for thinning of the CD storage boxes is more urgent. In response to this requirement, ‘the thickness of the CD storage box tends to become thinner year by year’, especially for 8c mCD CD storage boxes ^ This tendency is strengthened

C: \ Program Fi ies \ Patent \ 310379. Ptd page 8 4484 27 5. Description of the invention (5) Lie. With the thinning of such a CD storage case, for example, the distance between the outer case 3 8 1 and the disc holding portion 309 (distance D in FIG. 15) is much shorter than that of a conventional person. However, if the conventional CD ejector 401 is used in a thin CD storage case, the thickness of the pressing portion 411 will bring the upper side of the pressing portion 411 and the outer case 381 into a very close state. 1 On the other hand, The outer box 381 is generally made of resin or paper, so it is easy to bend due to external impact, etc., that is, the 'outer box 381 bent inward due to impact, etc.' will press the pressing portion 411 to make the holding piece 391 The elastic deformation toward the inside of the disc holding portion 309 weakens the force of the CD held by the disc holding portion 309. As a result, due to the spring pressure of the spring 420, the CD 10 may be detached from the disc holding portion while being stored in the CD storage case 302, and the cd may be damaged in the CD storage case. Especially for the single CDt, since the outer case 381 is made of paper and the distance D is shorter, it is easy to press the pressing portion 411 when a force is applied from the outside. [Summary of the Invention] In view of the problems of the conventional technology as described above, an object of the present invention is to provide a stronger spring force than conventionally used to detach and raise the CD from the disc holding portion of the CD storage case. Simply grab the CD ejector for the CD. Another object of the present invention is to provide a CD ejector which can be manufactured in a simple and low-cost manner as compared with the prior art. Furthermore, another object of the present invention is to provide a CD ejector which can be reliably mounted on a disc holding portion of a CD storage case and is not easily detached.
