ANTENNA-INTEGRATED NON-CONTACT IC CARD READING/WRITING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an antenna-integrated non-contact IC card reading/writing device which does not require the limitation of an installation location and the adjustment of the resonant frequency of an antenna, has high convenience and stable characteristics in installation, and is small and inexpensive.

SOLUTION: This device comprises a loop antenna 1 for supplying electric power and transmission data to a non-contact IC card by electromagnetic induction, and acquires reception data from the non-contact IC card by load fluctuation; a magnetic body 2 arranged closely on the back of the loop antenna 1; a first metallic plate 4 arranged on the back side of the magnetic body 2; and a second metallic plate 7 arranged on the back side of the first metallic plate 4, and having a size larger than the first metallic plate 4.
