2. Description of the Related Art FIG. 9 shows a CD storage case 8 in which the present invention and a conventional CD release device are used. FIG.
9 is a sectional view taken along the line VI-VI in FIG.
The state where the center of the storage case 8 is enlarged is shown. C
The D storage case 8 includes an outer case 81 that can be freely opened and closed, and an inner case 82 that is detachably attached to the outer case and has a disk storage recess 83. The disc storage recess 83 has a disc holding section 9 having a center hole at the center thereof. This disk holding unit 9
Zero elastically deformable holding pieces 91 are annularly arranged at intervals of 36 degrees via slits 92 to form a substantially cylindrical shape.

The CD storage case 8 shown in FIG. 9 is a case used for storing a CD having a diameter of 8 cm (8 cm CD / single CD). As another type of CD storage case, there is a CD storage case for a CD having a diameter of 12 cm (12 cm CD). The main differences between the CD storage case for 12 cm CD and the CD storage case for 8 cm CD are the following three points. The first difference is that the holding piece 91 is 3 in the CD storage case for an 8 cm CD.
While 10 pieces are arranged at 6 degree intervals, 12 holding pieces 91 are arranged at 30 degree intervals in the CD storage case for 12 cm. The second difference is that when comparing the distance (distance D in FIG. 10) between the outer case 81 and the disc holding unit 9, the CD storage case for 8 cm CD is longer than the CD storage case for 12 cm CD. D is short. The third difference is the 12 cm CD
The outer case 81 of the CD storage case is made of resin, whereas the case of 8 cm CD is often made of paper.

The CD stored in the CD storage case is
Several types of devices for detaching the storage case from the disk holding portion have already been proposed. As a typical example of such a conventional CD detaching device, there is a "compact disc ejector" disclosed in Japanese Utility Model Registration No. 3018285 as shown in FIG. FIG. 12 shows a state in which the conventional CD detaching device 101 is mounted on the CD storage case 8 of FIG.

Hereinafter, a conventional CD detaching device will be described with reference to FIGS. 11 and 12.

[0006] In FIG. 11, a CD detaching device 101 comprises:
Generally, a resin main body 110 having a pressing portion 111 and the like mounted on the disk holding portion 9 and integrally formed, a metal spring 120 attached to the main body 110, and the spring 120, the spring 12
A contact plate 130 made of resin for transmitting the urging force of 0 to the CD;
It is composed of

In the main body 110, the upper surface of the pressing portion 111 is pressed by a fingertip in a state of being placed on the disk holding portion of the CD storage case. On the lower surface side of the pressing portion 111, a spring support portion 112 for accommodating and fixing the base end portion of the spring 120 is provided.
The spring 120 is elastically deformed with the fulcrum as a fulcrum. Further, on the lower surface side of the pressing portion 111, there is provided a circumferential movement restricting portion 113 which is inserted into any one slit of the disk holding portion 9 and can be engaged with the holding piece 91.
The holding pieces 91 are provided on both sides of the circumferential movement restricting portion 113.
Vertical movement restricting portion 11 that can be engaged with the lower surface of
4 are formed.

The spring 120 supported by the spring support 112
Extends to the upper surface side of the pressing portion via a slit provided in the pressing portion 111. A contact plate 130 made of resin is attached to the tip of the spring 120. The spring 120 is configured to be elastically deformable from a position indicated by a solid line in FIG. 12 to a position indicated by a dotted line.

FIG. 12 shows a state in which the CD release device 101 shown in FIG.
10 shows a state in which 10 has been detached. In FIG. 12, C
The pressing portion 111 of the D release device 101 is
Is placed on top. The circumferential movement restricting section 113 is inserted into the slit 92 of the disc holding section 9 and regulates the movement of the CD detaching device 101 in the circumferential direction. Further, the vertical movement restricting section 114 is

[0010] In FIG. 12, the disk holding unit 9 is a CD.
The state of fitting with the opening 10 and holding the CD is shown by a broken line. When the pressing portion 111 is pressed from this state, the holding piece 91 is elastically deformed inward of the disk holding portion 9 and the force of holding the CD 10 by the disk holding portion 9 is reduced. When the force of pressing the CD 10 by the spring 120 exceeds the force of holding the CD 10 by the disk holding unit 9, the CD 10 is moved to the spring 1 via the contact plate 130.
It is lifted by 20 and detaches from the disc holding part 9 to reach the position shown by the solid line in FIG.

[0011]

As the demand for CDs increases, there is an increasing demand for thinner CD storage cases in order to store many CD storage cases in a small space. In order to meet such demands, the thickness of the CD storage case tends to be reduced year by year, and this tendency is particularly strong in a CD storage case for an 8 cm CD. As the CD storage case becomes thinner, for example, the distance between the outer case 81 and the disk holder 9 in FIG.
Is much shorter than in the prior art.

However, the conventional CD detaching device 101
Is used for a thin CD storage case, the pressing portion 1
Because of the thickness of 11, the upper surface side of the pressing portion 111 and the outer case 81 are in a state of being very close. On the other hand, the outer case 81
Generally, since it is made of resin or paper, it is easily bent by an external impact or the like. That is, the outer case 81 curved inward due to an impact or the like
Is pressed to elastically deform the holding piece 91 inward of the disk holding portion 9, thereby weakening the force by which the disk holding portion 9 holds the CD. As a result, due to the urging force of the spring 120, C
D10 is detached from the disc holding unit 9 while being stored in the CD storage case 8, and in some cases, the CD may be damaged in the CD storage case. In particular, in the case of a single CD, since the outer case 81 is made of paper and the distance D is shorter, the pressing portion 111 is easily pressed when a force is applied from the outside.

Further, the conventional CD detaching device 101 comprises:
There is a problem that productivity is poor because a complicated operation of assembling a plurality of members is required. Furthermore, the conventional C
The D separating device 101 has a drawback that it is difficult to reduce the cost because the assembly cost is required in addition to the cost for manufacturing a plurality of members.

Further, the separation of the CD by the conventional CD separation device 101 is performed by using a single spring 120 for the CD 10.
This is performed by pressing and pressing one point on the lower surface side (information recording surface side). However, a single spring CD
There is a case where the CD cannot be sufficiently detached from the disk holding portion of the CD storage case and raised because the urging force to the CD is insufficient. If the CD cannot be lifted sufficiently, it becomes difficult to grasp the CD.

Further, the conventional CD detaching device 101 is not provided with a member for preventing the movement in the horizontal direction (for example, the H direction shown in FIG. 12). Therefore, CD
The detaching device 101 may move in the horizontal direction, and may be detached from the CD storage case through the center hole of the disc holding unit 9 in some cases.

In view of the above problems of the prior art, an object of the present invention is to provide a thin CD detaching device which can be used for a thin CD storing case and has almost the same strength as a conventional CD detaching device. To provide.

Another object of the present invention is to form a CD detaching device integrally, so that the CD detaching device can be manufactured more easily and at a lower cost than conventional ones. Is to provide.
