<p><P>PROBLEM TO BE SOLVED: To provide a small adaptor for a memory card securing a desired communication distance when a memory card having a non-contact communication function is mounted thereon. <P>SOLUTION: On the surface of a base 3 composing an adaptor body, a card storage part 3a for storing a mini SD card is provided, and on the card storage part 3a, two through-holes 3e are formed correspondingly to two antenna connection terminals provided on the mini SD card. In addition, on the card storage part 3a, two contacts 9 are disposed with each of their bases inserted in each through-hole 3e. The tip of each contact 9 is provided with an elastic contacting spring piece 9b elastically contacting with an antenna connection terminal of the mini SD card to be inserted in the card storage part 3a. On the back surface of the base 3, a loop shaped antenna pattern 10 of multiple turns (for instance, three turns) is formed with one through-hole 3e as its starting point and another through-hole 3e as its end point. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
