Embodiment Construction

[0030] Now, the best mode for carrying out the invention will be described with reference to the accompanying drawings. The present embodiment is provided to exemplify identification performed when radio frequency tags formed in the same shape are respectively attached to a plurality of sheet articles of the same size. Sheet items include paper such as receipts, documents, or envelopes, plastic cards, compact discs, digital multi-purpose discs, and the like.

[0031] FIG. 1 is a block diagram depicting a schematic configuration of an article recognition device 10 in the present embodiment. The item identification device 10 is made up of the following components: a radio frequency tag reader / recorder 11; a controller 12 controlling the reader / recorder 11; a first tag communication antenna 13; a second tag communication antenna 14; Box 15. The switching box 15 is used to switch the tag communication antenna connected to the reader / writer 11 to the first tag communication anten...

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.

Description

Background technique [0001] The present invention relates to a device for identifying an item to which a radio frequency tag is attached, for example, a device for identifying bills, documents, envelopes, plastic cards, compact discs, digital multi-purpose discs and the like. [0002] In recent years, attention has been focused on a radio frequency tag system consisting of a radio frequency tag and a reader / writer. Typically, radio frequency tags are configured as an IC chip and antenna disposed on a small, thin, rectangular base. A specific identifier (ID) is set in the memory of the IC chip. The reader / writer communicates in a contactless manner using a radio with a radio frequency tag, and reads ID, etc. from the radio frequency tag. In addition, the reader / writer can write and read arbitrary data to and from the memory of the radio frequency tag. [0003] A collision proof function called anti-collision is used for communication control between the radio frequency tag a...
