WIRELESS TAG COLLECTIVE READING DEVICE, AND NETWORK ARTICLE MANAGEMENT SYSTEM
First Claim
1. A wireless tag collective reading device for collectively reading tag information from articles equipped with wireless tags each emitting the tag information in response to an electromagnetic wave, the device comprising:
- a rack which comprises storage areas to store the articles;
an antenna unit which applies the electromagnetic waves to the articles stored in the rack, and receives the tag information emitted from the wireless tags;
an electromagnetic wave controller which controls directivity, intensity, and phase of the electromagnetic waves emitted from the antenna unit;
a position controller which controls relative positions of the antenna unit and the rack;
a reader which reads the tag information from a signal received by the antenna unit;
an article detector which detects whether the articles are stored in the storage areas in the rack, respectively;
a counter which counts a total number of the articles stored in the storage areas in the rack from a detection result of the article detector; and
a checking unit which checks number of pieces of the tag information read by the reader against the number of the stored articles counted by the counter.

Abstract
A wireless tag collective reading device of this invention comprises a rack to store the wireless-tag-equipped articles which are mounted on the wireless-tag-equipped article by printing a chip portion and an antenna portion connected to the chip portion, the chip portion emitting tag information in response to electromagnetic waves, and an antenna unit which applies, to the wireless-tag-equipped articles stored in the rack, electromagnetic waves for the emission of the tag information, and receives electromagnetic waves for the tag information emitted from the wireless tag, wherein the device controls the directivity, intensity, and phase of the electromagnetic waves emitted from the antenna unit to apply the electromagnetic waves to the wireless-tag-equipped article at a given position stored in the rack, controls the relative positions of the antenna unit and the rack, and reads the tag information from a signal received by the antenna unit.
