<p><P>PROBLEM TO BE SOLVED: To provide an article management system, a radio tag, and radio tag communication equipment for enabling a user to surely grasp a radio tag to be retrieved by the light emission pattern of the light emission means of a radio tag in the case of retrieving his or her desired radio tag by a plurality of radio communication equipment. <P>SOLUTION: This article management system is provided with: a tag antenna for transmitting/receiving information: a radio tag circuit part connected to the tag antenna; a radio tag equipped with a light emission means for emitting the rays of light with a plurality of light emission patterns; and a plurality of radio tag communication equipment equipped with a device antenna for transmitting and receiving information to/from the radio tag. The radio tag communication equipment is provided with a light emission instruction information transmission means for transmitting a light emission instruction information for instructing light emission through the device antenna to the light emission means. The radio tag is provided with a first control means for, when receiving the light emission instruction information transmitted by the light emission instruction information transmission means through a first antenna, controlling the first light emission means to emit the rays of light with light emission patterns different by radio tag communication equipment. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
