Abstract

An IC tag communication relay device is provided with an antenna section, lead lines and input/output unit. The antenna section is equipped with one or more antennas for transmitting and receiving electromagnetic radiation to and from IC tags. The lead lines are connected to each antenna for transmitting electrical signals corresponding to transmitted and received electromagnetic radiation. The input/output unit is arranged outside of the antenna corresponding to each antenna connected to the lead lines.
