<P>PROBLEM TO BE SOLVED: To execute a predetermined process properly according to the motion of a wireless IC device to an antenna, independently of a distance relationship between the wireless IC device and the antenna and an antenna installation state. <P>SOLUTION: An electromagnetic wave attenuation sheet 9 is attached to a half region of an antenna 7. A CPU 1 refers to a data section that is included in a set of data indicating a radio field intensity sequentially acquired from a radio field intensity detector 8 and that is affected by the electromagnetic wave attenuation sheet 9, and thereby recognizes the motion of a non-contact IC card 10 to the antenna 7, and then performs instruction of a predetermined process according to the motion of the non-contact IC card 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
