<P>PROBLEM TO BE SOLVED: To provide a non-contact IC reader/writer for transmitting and receiving information with non-contact IC media without generating any interference in a radio wave even when a plurality of non-contact IC reader/writers are installed adjacently to each other. <P>SOLUTION: Normally, not any radio wave but an infrared ray/near infrared ray is generated, and the presence of reflected rays of light on non-contact IC media is detected so that electric wave occurrence is always eliminated. <P>COPYRIGHT: (C)2007,JPO&INPIT |
