<p><P>PROBLEM TO BE SOLVED: To provide an IC card holder which enables a data communication by allowing only an IC card facing a card reader device response a radiated magnetic field when a plurality of noncontact IC cards are held over the card reader device while being held in the card holder. <P>SOLUTION: The holder includes a partition plate 110 which is an electric conductive object, and disposition adjusting means 120 for making a disposition of the noncontact IC card 10 relating to the partition plate 110 to be a predetermined state. A distance between the partition plate 110 and the noncontact IC card 10 is adjusted between a communication allowable distance L1 and a communication disable distance L2 by the disposition adjusting means 120. The communication allowable distance L1 is a distance in which data communication between the noncontact IC card 10 and the reader device 20 is enabled even though influence of a magnetic field of an eddy current generated in the partition plate 110 is received to the radiated magnetic field form the reader device 20 facing the noncontact IC card 10. The communication disable distance L2 is a distance in which the data communication with the reader device 20 becomes disabled by receiving influence of the magnetic field of the eddy current generated in the partition plate 110 by approaching to the partition plate 110. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
