The second portion 114 extends away from the disk storage device 80 in a direction similar to the card face 92. The interior is at least partially clamped to the snap arm 87. A receptacle 1 16 extends between the end wall 1 〇 8 and the latching surface 90 and extends between the second portion 114 of the male arm 110. When the disc storage device 80 is assembled in a latching position, at least a portion of the latching arm 87 is received between the slots 1 16 (see Figure 5). The convex arm 1 1 〇 -11 - 201239877 the second portion 114 is partially clamped to the snap arm 87 and can be transported to prevent any accidental looseness or the like. In one embodiment, a central portion 104 of the snap face 90 is fastened (i.e., straight through). extends between the arms 11 ( (see page). In another embodiment, the snap face 90 includes an "interrupted" central portion 104 that is secured between the flanges 97. The "interrupted" is used for a snap face and does not pass straight through the entire surface. And the central portion 1〇4 type and the change of the contour. In an embodiment, the central portion 104 is and corresponds to the curved portion 100 of the rib 98 (see Fig. 6). However, in the technical field It will be appreciated by those skilled in the art that the central portion can include other shapes and aspects. For example, the central portion 1 〇 4 is generally shaped (see Figure 7). In another embodiment, The flange 97 of the snap ring does not include the central portion 104 (i.e., the flange 97 is connected to the central portion 104) (see Figure 8). The center portion 1 0 4 (see Figure 6) The first direction extends to the bottom end of the sheet storage device 80. In one embodiment, the manipulation surface is formed into the shape of a human finger. The central portion 1 〇4 is remote from the control surface 106, The abutment of the control surface 106 is more clicked to the bottom end 118 of the disc storage device 80. Thereby, the leverage can be advanced In order to reduce the force to manipulate the snap arm 87, the disc storage device 80. The latching surface 92 of the tab 85 is against the flange of the latching surface 90 so that when the disc storage device 80 is assembled, the buckle is buckled. The cover 86 is attached to the portion 84, for example, as shown in Fig. 6. In the process of adjoining the face 92, the level 9 is shown in Fig. 1, and the description is configurable, and the 104 square S 90 is not exposed by the plate 106. Moved to open, 97, base area

S -12- 201239877 'The control surface 106 cannot be disturbed by the central portion 104 of the snap face 90. In the latching surface 92 of the present embodiment, one of the ends 89 of the latching arms 87 can be deflected by a first distance D1 as shown in FIG. The central portion 104' of the snap face 90 can be deflected by a second distance D2 from the end 89 of the snap arm 87. In an embodiment, the first distance D1 is greater than the second distance D2 (see Figure 6). Such an arrangement includes the manipulation surface 1 〇 6 being exposed to the bottom end 1 18 of the disc storage device 80. The first Figure A illustrates a machine 70 that utilizes the force F on the latch arm 3 2 to the interior 28 of the disk storage device 10 to manipulate the snap arms 32 of the buckle cover 18. Although this embodiment is an illustrative condition of the disc storage device 10, a similar process can be applied to the manipulation of the snap arm 87 of the disc storage device 80 of the second embodiment. In this embodiment, the force F is applied to the second surface 44 below the rib 48 (or the steering surface 106 of the disc storage device 8A of the second embodiment). The machine 70 of this embodiment has a male arm 72 that abuts the second surface 44 for utilizing the force F. The raised arms 72 are moved a sufficient distance to push against the snap faces 64 without the need to worry about the snap faces 36 to align the tabs 46 with the pockets 60. The elastic force of the latching arm 32 is pressed against the inner portion 28 of the storage box portion 14 in such a manner that the latching surfaces 36 and 64 can cooperate to keep the disc storage device 1 closed. status. The force F can fully overcome the skew. When the force F on the latch arm 32 is maintained, the cam 72 moves a second distance D2' to remove the buckle cover 18 from the disc storage device 1 as shown in Fig. 10B. In this figure, the direction of the pair - the distance D2 and the direction of the force F are in a horizontal relationship. The rib 48 (or the rib 98 of the disc storage device 8 〇 -13 - 201239877) assists the male arm 72 in removing the buckle cover 18 from the base portion 16 and the storage case portion 14. In another embodiment, the snap arm 32 and the buckle cover 18 can be manually operated to remove the buckle cover 18. For example, a person can press the surface 44 and utilize the crimp block 50 to manipulate the buckle. In yet another embodiment, a person can press the control surface 106 to release the latching arm 87 of the disc storage device 8°. In the illustrated embodiment, various features are included, such as providing a production machine or a human hand and Improved interaction between the disc storage devices provides a means of loosening the snap arms. The illustrated embodiments include a combination of improved snap arms and base features. For example, the position of the snap arms 32 in the receptacle 60 of the disc storage device 10 can provide a relatively stable relationship with respect to the previous arrangement, i.e., a snap arm strap and the outer end edge of the base. In another embodiment, the improved design of the snapping arm 87 and the snap face 90 of the disc storage device 80 creates a lower abutment point on the snap arm and provides improved leverage. Lower the required force to release the snap arm 87. The benefits of these familiar techniques will utilize a carded snap arm, a snapped base portion, a rib or press block or any combination of these features to meet the particular needs.
