RF tagged article
First Claim
1. An RF tagged article whose data is readable by an RF tag reading apparatus, the article having a planar surface, comprising:
- an RF tag comprising an IC chip and an antenna connected to the IC chip that are integrally molded with a covering material, the RF tag retaining the data;
a reflector of an electrically conductive material; and
a holding member affixed to the article for holding the RF tag and the reflector thereon, the antenna of the RF tag and the reflector being arranged in parallel with each other at a predetermined distance between them, wherein the antenna is situated closer to an edge line of the planar surface of the article than to the reflector in parallel with the edge line in a state that the holding member is affixed to the article.

Abstract
An RF tag reading apparatus reads information from RF tags affixed to postal envelopes by a single operation. An article container contains a large number of postal envelopes provided with RF tags. A reader antenna, which is connected to an interrogator via a coaxial cable, is disposed under the article container. Maximum gain directions of the RF tags of the respective postal envelopes are uniformly directed to the reader antenna. The respective postal envelopes contained in the article container are arranged face to face with each other in a direction orthogonal to the maximum directions of the RF tags. Since a maximum gain direction of the reader antenna is oriented toward a base end surface of the article container, the maximum gain directions of the RF tags are opposed to the maximum gain direction of the reader antenna.
