RFID GATE SYSTEM

To provide an RFID gate system such that precision of reading of an RFID tag is easily adjusted according to a state of an object.SOLUTION: A gate 10 has a wall in a cylindrical shape which has both ends opened and the inside of which is a cavity. An antenna 30 is installed on an inner surface of the wall in the cylindrical shape, and radiates a radio wave to communicate with an RFID tag that an article comprises when the article passes inside the gate 10. A position adjustment part 41 has an operated part 42a which is operated from outside, and displaces the position of the antenna 30 in an adjustment direction crossing the direction in which the article passes inside the gate 10 according to an operation state of the operated part 42a.SELECTED DRAWING: Figure 2 【課題】対象物の状態に応じたＲＦＩＤタグの読み取り精度の調整が容易なＲＦＩＤゲートシステムを提供する。【解決手段】ゲート１０は、両端が開口し内部が空洞の筒形状の壁を有する。アンテナ３０は、筒形状の壁の内面に設置され、電波を放射して、物品がゲート１０の内部を通過した際に、物品が備えるＲＦＩＤタグと交信する。位置調整部４１は、外部から操作される被操作部４２ａを有し、被操作部４２ａの操作状態に応じてアンテナ３０の位置を、ゲート１０の内部を物品が通過する方向に対して交差する方向である調整方向に沿って変位させる。【選択図】図２
