A mount sheet having a plurality of radio tags attached at an interval to it is run over a radio communicating section. The radio communicating section has a metal member providing a conveying surface with a slit formed therein. A dielectric member is arranged on a lower surface of the metal member with a projecting section inserted into the slit and, by doing so, the top surface of the projecting section is set flush with the top surface of the metal member. An antenna of the radio communicating section is located beneath the projecting section of the dielectric member and this antenna is held within the metal case. When any radio tag being an object of a radio communication is located over the slit, the radio communicating section positively makes radio communication with the radio tag through the antenna.

A quadrature demodulation device effectively utilizes the result of quadrature detection in order to improve demodulation efficiency. The quadrature modulation device includes a quadrature detector DT which performs quadrature detection on a reception signal obtained by receiving a radio wave from a radio frequency identification tag, to generate an in-phase signal and a quadrature-phase signal, and a demodulation circuit DM which detects a preamble of a particular transition pattern in at least one of the in-phase signal and the quadrature-phase signal and which decodes the at least one of the in-phase signal and the quadrature-phase signal to obtain data succeeding the preamble, the demodulation circuit DM further performing error detection on a decoding result to check for errors.

There are provided a barcode reader for reading an article code in a barcode form from an article tag, and an RFID tag reader for reading a shelf code from a shelf tag in a non-contact wireless manner. The article code read by the barcode reader is stored in an article code memory, and the shelf code read by the RFID tag reader is stored in a shelf code memory. There are also provided an information processing unit, a control unit and a transmission unit. The information processing unit is controlled by the control unit to process the article code and the shelf code as one set of information for article management. Then, the transmission unit transmits the processed information to a personal computer.

Tag reading apparatus

Tag information which has been previously read but is not currently read is retrieved every time tag information is collectively read by a wireless tag reading device. When corresponding tag information is detected, sales information of a commodity is acquired from this tag information, and the acquired sales information is registered in a sales registering section. Further, display contents in a display device are changed in response to detection of the tag information which has been previously read but is not currently read. Furthermore, when information concerning a commodity for sale is input through a barcode reader, sales information of the commodity is acquired from this input information, and the acquired sales information is registered.

Commodity sales registration processing system and commodity information registering apparatus

Radio tag issuing apparatus

There is disclosed a commodity information registering apparatus which registers commodity information while a commodity is moved, comprising a radio tag reading section which reads a radio tag within a first field to acquire commodity identification information stored in the radio tag, an optical reading section which reads a code symbol within a second field to acquire commodity identification information described in the code symbol, and a registering section which registers one of the commodity information corresponding to the commodity identification information acquired from the radio tag and the commodity information corresponding to the commodity identification information acquired from the code symbol.

A label and RFID tag issuing apparatus comprises a recording apparatus that records information on a production label and an RFID tag reader/writer that writes and reads part of the recorded information to/from an RFID tag. This label and RFID tag issuing apparatus writes a production number to the RFID tag attached to the container if a container for containing an article or articles carrying the production label and RFID tag is judged to be on the container loading plate. The apparatus, subsequently confirming presence of the container on the container loading plate, records on the production label production information including bar-code data corresponding to the production number that has been written to the RFID. Thus, information recorded on the production label and information stored in the RFID tag are tied, and thereby accidental affixing of a wrong production label onto the container can be prevented.

Label and RFID tag issuing apparatus

A tag unit comprises two RFID tags arranged nearly parallel with each other, each RFID tag including an antenna, tag transmission/reception section, and storage section. The tag unit stores different serial numbers in the respective storage sections. A tag unit reading/writing apparatus writes the different serial numbers and common data in the storage sections of the respective RFID tags, and retains the same serial numbers of the respective RFID tags in its storage section 18. The tag unit reading/writing apparatus judges validity of reading and reusability of the tag unit, when it successfully reads both of the serial numbers and the data stored in the storage sections of the respective RFID tags.

Reading/writing apparatus of tag unit

There is provided an article management system having a plurality of article management apparatus that are arranged at the respective process stage position in a production line and read information by RF tag readers from an article RF tag affixed to each of articles contained in a case and a case RF tag attached to each of the cases. A server connected to the respective article management apparatus for managing ID information on the articles, quantity of the articles, current process stage positions for each of the cases and other items. With this system, production management for the articles contained in the cases can be performed in a short time without being interrupted, even if some of the tags have become damaged and reading from the tags is impaired.

Article management system and article management apparatus

A checkout device including a conveying section for conveying an article in one direction, an optical scanner for scanning the article conveyed by the conveying section with a scanning light beam to read an article code affixed thereto, and a registration processing section for registering the article based on the article code read by the optical scanner. The optical scanner is provided with a variable scanning range to which the scanning light beam is applied, and the registration processing section includes control means for detecting physical features of the article conveyed by the conveying section and for controlling the scanning range of the optical scanner to be optimized for reading the article code affixed to the article based on a conveying position and the detected physical features of the article.

Checkout device

A checkout system has a checkout lane which includes a belt conveyor for carrying articles in one direction a video camera for imaging an article which is being carried by the belt conveyor, and a bar code scanner for reading out a bar code of the article which is being carried by the belt conveyor. A CPU recognizes and registers the article on the basis of at least one of the bar code read out by the bar code scanner and the physical features of the article which are included in an image obtained by the video camera.

A laser beam emitted from the beam emitting unit is deflected for scanning by a reflector rotated by a scanner motor. The deflection scanning beam passes through a meniscus lens device provided close to the reflector, and converges the laser beam on an image-forming surface. The meniscus lens device has an incident surface, a radius of curvature of which is set smaller than that of an output surface thereof, with a convex surface thereof facing the image-forming surface. The laser beam emitting unit, the reflector, the scanner motor, and the meniscus lens device are all integrally built in a housing.
