- the pressing member 6 is made of a metal elastic body and is provided above each of the two SD memory cards 5 attached to the connector 4.
- the pressing member 6 is shaped so as to cover these two SD memory cards 5. I'm in love.
- the present invention has a problem that the simple structure in which the pressing member 6 is simply covered with the SD memory card 5 of the PC card is not sufficient. That is, the dimensions of the SD memory card 5 and the PC card are strictly stipulated by the standard, and of course, there is no extra space for providing the pressing member 6. For this reason, considerable effort is required to arrange the pressing member 6 on the PC card. This point will be explained first.
