RADIO TAG COMMUNICATION DEVICE

摘要

[PROBLEMS] To effectively and rapidly detect positions of a plurality of target radio tag circuit elements. [MEANS FOR SOLVING PROBLEMS] A radio tag communication device includes an RF communication control unit (9) and a reader antenna (3) for performing radio communication with the radio tag circuit elements To. The radio tag communication device specifies a tag ID of at least one radio tag circuit To element To to be searched in a detection tag list and acquires information from the specified radio tag circuit element by performing search communication via the RF communication control unit (9) and the reader antenna (3) in a plural tag detection mode. The radio tag communication device performs communication for position detection of the specified radio tag circuit element To from which the information has been acquired in a single tag detection mode and detects the position of the specific radio tag circuit element To according to the communication result.
