ANTENNA INTEGRATED TYPE NON-CONTACT IC CARD READER/WRITER

摘要

PROBLEM TO BE SOLVED: To provide a miniaturized and thin antenna integrated type non-contact IC card reader/writer which is not easily affected by limitation to installation places and the drawing of a coaxial cable, eliminates the need of controlling the resonance frequency of an antenna and has high convenience for installation and stable characteristics.;SOLUTION: A loop antenna for supplying power and transmission data to a contactless IC card by electromagnetic induction and acquiring receiving data from the contactless IC card by load variation and a control substrate loaded with a resonance matching circuit part and a control part for controlling a radio transmission part and a radio receiving part are stored in a shield case and the center axis of the loop antenna in the thickness direction and the center axis of the shield case in the thickness direction are approximately aligned and assembled in the aperture surface of the loop antenna.;COPYRIGHT: (C)2004,JPO&NCIPI
