Abstract
(EN)
[PROBLEMS] To prevent prolonging of a communication time because of a plenty of identification slots and reduce the communication time, thereby performing efficient communication. [MEANS FOR SOLVING PROBLEMS] An interrogator (100) for transmitting/receiving information to and from a plurality of radio tags (Ts) having an IC circuit section (150) and an antenna (151) comprises an AM modulation section (24) for generating a response request command to acquire the radio tag information on the IC circuit section (150), high-frequency transmission/reception sections (34A to 34D) and antenna elements (1A to 1D) capable of transmitting the response request command to the radio tags (Ts) and of receiving response signals transmitted from the radio tags (Ts) according to the response request command, while dividing the response signal into a plurality of the identification slots, a control procedure of Step S5 of setting a communication condition under which the information is transmitted/received to and from the radio tags (Ts), and a number-of-slots control section (47) for controlling the number of identification slots (M) under the communication condition.

L'objet de l'invention est d'éviter l'allongement de la durée de communication du fait de nombreux intervalles d'identification, et de réduire la durée de communication, réalisant ainsi une communication efficace. L'interrogateur (100) d'émission/réception d'informations de multiples étiquettes radio (Ts) ayant une section de circuit CI (150) et une antenne (151) comprend une section de modulation AM (24) pour générer une commande de requête de réponse pour acquérir les informations d'étiquette radio à la section de circuit CI (150), des sections d'émission/réception haute fréquence (34A à 34D) et des éléments d'antenne (1A à 1D) pouvant transmettre la commande de requête de réponse aux étiquettes radio (Ts) et recevoir des signaux de réponse émis par les étiquettes radio (Ts) en fonction de la commande de requête de réponse, tout en divisant le signal de réponse en de multiples intervalles d'identification, une procédure de commande à l'étape S5 de réglage de condition de communication sous laquelle les informations sont transmises/reçues des étiquettes radio (Ts), et une section de commande de nombre d'intervalles (47) pour commander le nombre d'intervalles d'identification (M) en condition de communication.
