Device for recognizing articles having radio frequency tag attached to the articles
First Claim
1. An article recognition device, comprising:
- a first tag communication antenna having an axis of directivity in a direction facing a direction of an axis of directivity of a first tag antenna that a first radio frequency tag has, the first radio frequency tag being provided on an article and shaped to have a short edge and a long edge which is greater than the short edge;
a second tag communication antenna having an axis of directivity in a direction facing a direction of an axis of directivity of a second tag antenna that a second radio frequency tag has, the second radio frequency tag being provided on the article and shaped to have a short edge and a long edge which is greater than the short edge; and
a scanner base having provided thereon the first tag communication antenna and the second tag communication antenna, wherein the respective axes of directivity of the first tag communication antenna and the second tag communication antenna cross each other.

Abstract
An article recognition device includes a scanner base. A first tag communication antenna and a second tag communication antenna are provided on the scanner base. A direction of an axis of directivity of the first tag communication antenna faces a direction of an axis of directivity of a first tag antenna that a first radio frequency tag provided on an article has. A direction of an axis of directivity of the second tag communication antenna faces a direction of an axis of directivity of a second tag antenna that a second radio frequency tag provided on the same article has. The respective axes of directivity of the first tag communication antenna and the second tag communication antenna cross each other.
