Description of the invention (8), disc removal history detection sensor hole 3 7, disc cartridge detection sensor hole 3 8, claw 40, and accidental insertion prevention groove 41. (Please read the precautions on the back before filling this page.) Here, the disc removal history detection sensor hole 3 7 is set to the open state, and it is often constructed by keeping the information corresponding to the open state. This is to consider that when the operator installs the disc cartridge 3 0 0 in the recording / reproducing device, even if the history is not taken out from the disc of the cartridge 31, through the opening 3 3, the hand accidentally touches the disc 3 2 Information record side, etc. The 3 and 6 series can be installed and detachably hold the elastic deformation part for the disc 32, and the 39 series cooperates with the aforementioned elastic deformation part 36 to hold the fixing flange part for the disc 32. The flange portion 39 restricts the disc 32 from moving in the thickness direction. The front end face of the 4 2 series case 3 1 is equipped with the 8 cm disc cassette 1 0 0 installed in the recording / reproducing device, which will not hinder the cover switch mechanism (not shown) provided in the recording / reproducing device.

Figure 7 is a perspective view of the surface side of the box 3 1 with the disc 32 removed. Here, 4 4 is a disc accommodating section for accommodating the disc 32. Fig. 8 is a perspective view showing an enlarged portion of the elastic deformation portion 36 of Fig. 7. The elastic deformation portion 36 is a unilateral fixed beam structure that can be deformed in the thickness direction of the disc 32 included in the box 31, and the front end of the unilateral fixed beam is formed by the top of the box 31 being exposed. In order to avoid conflicts with components on the side of the device when it is mounted on the recording / reproducing device or when it is taken out, it is impossible to perform the device or take out operation. A guide portion 4 with a sloped portion that often enters the thickness of the box 31 is provided at the front end 5. This guide 45 also serves as a diameter-direction position-limiting wall that restricts the position of the disc 32 in the diameter direction, and it is included in this paper standard that applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -11-569190 A7 B7 V. Description of the invention (9) The disc 3 2 of the box 31 is restricted by the diameter position limiting wall and the position in the diameter direction. On the other hand, the underside of the single-sided fixed beam is used as a disc (please read the precautions on the back before filling in this page). 3 The height direction restricting wall restricts the position in the height direction. Here, in this embodiment, although the structure in which the guide portion 45 has a function of restricting the diameter direction is formed, the position regulating wall of the diameter direction and the guide portion 45 may be separated from each other. 4 6 is a deformation restricting portion that restricts the deformation of the elastic deformation portion 36. When the elastic deformation portion 36 is deformed in the thickness direction of the disc 32 contained in the box 31, it is within the elastic deformation range and the elastic deformation portion. 36 abuts to prevent deformation beyond the elastic deformation range of the elastic deformation portion 36. Fig. 9 is a perspective view showing a state where the elastic deformation portion 36 is in contact with the deformation restricting portion 46 in the elastic range. In this figure, in order to make the above-mentioned abutment state easier to understand, the disc 32 which deforms the elastic deformation portion 36 is omitted. As is clear from Figs. 8 and 9, the opposing portions of the elastically deformable portions 36 are opened in a window shape. By adopting such a structure, the effect of making a mold for a box having an elastically deformable part becomes easy.

When the operator holds the disc 3 2 in the state shown in FIG. 5 (the operator's hand is not shown), the disc 3 2 is lifted up, and the elastic deformation portion 36 of the box 31 is directed to the disc thickness direction. (Above) is deformed, and a part of the disc 32 is exposed to the thickness of the box 31. Further, by pulling out the disc 3 2 in the direction of the arrow A, the disc 32 is separated from the case 31 to complete removal. Figure 11 is an oblique view showing the finished state. This paper size applies the Chinese National Standard (CNS) A4 specification (21 × 297 mm) -12-569190 A7 B7 V. Description of the invention (10) In the case where the disc 3 2 is housed in the box 31, by one side Make the disc 3 2 submerge into the elastic deformation part 36 of the box 31 and store it on the side (please read the precautions on the back before filling this page). The disc storage part 4 4 passes the state of Fig. 10 to the figure. The containment of 5 is completed. Here, the bending strength of the elastic deformation portion 36 will be described. In order to take out the disc 32 from the case 31 of this embodiment, the elastic deformation portion 36 needs to be deformed by about 1 mm in the thickness direction. If the aforementioned deformation is obtained with a force of about 0.5 to 0.6 N, the disc is easy to come in and out, and it is ideal in operation. That is, the design is appropriate so that the Mises stress of the elastically deformed portion becomes 2 2 MPa (when the load is 0.55 N). Compared with the Mises stress (80 ~ 90 MPa) of ordinary bending strength, this is a sufficient margin. On the other hand, it is desirable that the fixing flange portion 39 is not elastically deformed even when the same degree of force is applied. If the amount of elastic deformation when the force is about 0. 5 to 0. 6 N is less than 0. 0 0 2 m, it is considered that the aforementioned requirements can be satisfied. That is, the Zeiss stress of the fixed flange portion 39 is designed to be 1.5 MPa (at a load of 0.55 N) or less.

Description of the invention (12) In this state, the elastic deformation part 4 7 is pressed and deformed in the direction of arrows C and D respectively. On the other hand, the disc 32 is moved in the direction of the arrow B, and abuts against the rising portion of the disc accommodation portion 44. In this state, the disc 32 is pushed down further than the fixing flange 39. Here, if the plucking force in the direction of arrow B given to the disc 32 is removed, the disc 32 is moved to the opposite side of the arrow B by the elastic restoring force of the elastic deformation portion 47, and enters the lower side of the fixed flange 39. And complete containment. Thus, in the second embodiment, when the disc 32 is taken out or received, the elastic deformation part needs to be deformed and the disc is lifted (depressed) in two steps. Therefore, the disc is removed and the like. By comparing the first embodiment with the one-step operation, the disc 32 can be held more reliably. Next, a third embodiment will be described. FIG. 15 is a plan view showing the front surface side of the third disc cartridge 500, and FIG. 16 is a plan view showing the back surface side.

Description of the invention (14) One of DVD-RAM, DVD-R, D or DVD + RW can build a system with rich interchangeability of disc devices between devices. (Please read the precautions on the back before filling in this page.) In the above embodiment, although the box 31 is configured to be used in the same recording / reproducing device as the 8 cm disc cartridge 1000, it may be configured. It is constructed by using the same recording / reproducing device as the 12 cm disc cartridge 200. In addition, it is not limited to the configuration of a recording / reproducing device which is the same as the disc cartridge. Even if the recording / reproducing device can be constructed by using only the disc cartridge 300 of the present invention, there is no problem. Here, it is assumed that the same recording and reproduction device as the 12 cm disc cartridge 200 is used. The outer shape of the box 31 is set to be slightly the same as that of the 12 cm disc cartridge. The disc 32 has a diameter of about 120 mm and a thickness of about 1.2 mm, and the type can be DVD-RAM, DVD-R, DVD-RW, or DVD-RW printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. one of them. In addition, in a case where the disc cartridge 300 is used only for the recording / reproducing device, although the outer shape of the casing 31 and the diameter and thickness of the disc 32 included therein can be arbitrarily set, but for miniaturization, The outer diameter of the disc in at least one place of the box 3 1 (equivalent to the outer dimension of W or D in FIG. 5) is set to 1.2 times or less the diameter 4 of the contained disc 32. According to the above-mentioned invention, a disc cartridge having a simple structure and an easy removal of a disc can be obtained. In addition, since the disc cartridge is interchangeable with an existing disc cartridge, it can be installed in an existing recording / reproducing device.
