Abstract:
PROBLEM TO BE SOLVED: To provide a communication device and the like that identify a tag (work) which is to be an object of a communication process by using a simple configuration.SOLUTION: A control unit of a communication device performs integration processing, for each RF tag passing through a communication available area in the vicinity of the communication unit, to integrate strength of reception signals received from the RF tag by a communication unit (S5). In the integration processing, integration is performed while weighting such that a calculated integration value gets larger than a previous integration value whenever strength of each reception signal is integrated. When the RF tag moves to a predetermined position in the communication available area (S9), an identifier of an RF tag with the largest integration value among the integration values of the respective RF tags is transmitted to an upper-level apparatus.SELECTED DRAWING: Figure 8
