In FIG. 1, reference numeral 1 denotes a computer card showing an example of a card for information processing equipment, and 2 denotes a storage case. At present, the computer card 1 has three types of external appearances, that is, one in which upper and lower reference surfaces 5 and 5 are formed in a flat shape without any convex portion as shown in FIG. As shown in (B), the upper and lower reference surfaces 5.5 are standardized to have flat convex portions 6 having different heights at the center of each (for example, PCMCIA standard, JEIDA standard, etc.). In order to make all three types compatible, the vertical length L and the horizontal length W have the same dimensions, and have a connector 3 at one end in the vertical direction and a predetermined length on both sides at the other end in the vertical direction. The ground clips 4.4 are provided at the positions in an exposed state. The only difference is the total thickness H, but the thickness h between the upper and lower reference planes 5 of the type shown in FIGS. 4A and 4B is the same as the total thickness H of the type shown in FIG.

A conductive buffer 13 formed of urethane foam or sponge rubber mixed with a conductive substance such as carbon black or copper sulfide is attached to the body 10 and the lid 11, respectively. The buffer 13 on the side of the body 10 is formed in a tray shape having a concave portion 14 having a shape corresponding to the outer shape of the computer card 1, and a bottom wall portion 13a for closing the bottom of the concave portion 14 and a concave portion on the upper surface of the bottom wall portion 13a. And a peripheral wall portion 13b integrally formed to protrude to form the peripheral portion 13b.

The concave portion 14 has a first concave portion 14a having a plane rectangular shape substantially the same as the maximum planar size (L × W) of the computer card 1, and a concave portion formed in the bottom wall 15 of the first concave portion 14a. The second concave portion 14b, which is slightly smaller than the first concave portion 14a and slightly larger than the planar size of the convex portion 6 of the computer card 1, is formed in a reverse convex shape in cross section. It is closed by the wall 13b (see FIG. 3). The outer periphery of the reference surface 5 of the computer card 1 is received and supported on the bottom wall 15 of the first recess 14a. The depth of the second concave portion 14b is adjusted so as to correspond to both the computer cards 1 of FIGS. 4A and 4B.

The projections 16 on the side that does not come into contact with the ground clips 4 come into contact with the side surface of the computer card 1 so as to exhibit a function of preventing backlash in the recess 14 of the card 1. Further, a notch 17 is provided between the front and rear convex portions 16 in the peripheral wall portion 13b to facilitate picking out the computer card 1 in the concave portion 14.

On the other hand, the buffer 13 on the side of the lid 11 is formed in a flat plate shape, and as shown in FIG. 2, when the lid 11 is closed, it overlaps the buffer 13 on the side of the body 10 and is exposed in the recess 14. One side of the computer card 1 is covered. The buffer 13 on the side of the lid 11 forms a window hole 19 in the center, and the computer card 1 is opened from the transparent lid 11 through the window hole 19.

The surface 5 is easily bent and deformed into a concave shape, and the wide surface 5 is stored in the storage case 2.
When an external force is applied to the ground clip, the built-in IC or the like may be damaged. However, since the ground clip 4 is provided on the narrow circumferential side surface as one flat body in a bridge shape between the upper and lower cases 1a and 1b, The holding force of the portion 16 and the external force applied via the convex portion 16 are
Added to and firmly received by the built-in I
