2. Description of the Related Art In a field of sales management and inventory management, a bar code system is widely used as a means for holding information on articles and commodities. In such a barcode system, a barcode indicator that displays information on an article or product is printed on a backing sheet or the like and attached to such an article or product, and used for product management and sales settlement at a sales floor. ing. In many cases, the barcode marker is already printed in the packaging process, such as being printed directly on the surface of an article or product, in addition to being printed on the backing paper. Such barcode signs are limited in the amount of information to be mounted, and only display very limited data such as part numbers and prices, and are not suitable for mounting a lot of information. Very widespread due to convenience. On the other hand, there is a request from a site that handles more information, and a system in which another system coexists in addition to a bar code sign is becoming widespread.

[0003] As one of such other systems, a small and thin information recording / reproducing apparatus called an IC tag, which has a built-in semiconductor memory, that is, an "information tag" has been rapidly spreading recently. Information tags can carry a greater amount of information than barcode signs and can be rewritten, so the coexistence of barcodes and information tags is an advantage of barcode signs. An information management system having both the effect of preventing data tampering using the characteristic that updating is impossible by forming a mark by printing and printing and the advantage of an information tag is possible.

Conventionally, in this initial issuance operation, an operator performs designation input for each article of interest, accesses a corresponding record in the master file, and then writes the extracted information to an information tag. For this reason, there is a problem that the amount of work is enormous when the number of target articles is large, for example, tens of thousands to hundreds of thousands or more, and the required time is also long. Therefore, there has been a demand for a technique that shortens the time required for one operation and simplifies the time required for the operation, thereby efficiently performing initial issuance.

Here, the main information tag TF is placed at a position where the main information tag reader / writer tfRW can react to an electromagnetic field by mutual guidance in a non-contact manner, and is affixed to a housing or the like of the target object Mat,
It is configured to receive, record, and reproduce information related to the article Mat. On the other hand, the main information tag reader / writer tfRW is placed at a position where the main information tag TF can be contacted with the electromagnetic field by mutual induction without contact.

To explain the actual operation, when information is exchanged between the main information tag TF and the main information tag reader / writer tfRW, in the non-contact type, at least the main information tag TfRW is generated by the electromagnetic field formed by the main information tag reader / writer tfRW.
The information tag needs to be located in the area where F is sensitive. Therefore, the main information tag TF and the main information tag reader / writer tfRW are relatively close to each other so that the main information tag TF is sensitive to the formed electromagnetic field. Normally, for example, a handy type main information tag reader / writer tfRW is moved to approach an article Mat with a main information tag TF attached thereto at a stationary position, or the main information tag TF ( Specifically, an operation of moving and approaching the article Mat) with the main information tag TF attached thereto is executed. These approaching operations are executed, for example, by an operator performing an operation of “over” one of them. Accordingly, the main information tag TF exchanges information with the main information tag reader / writer tfRW in response to the electromagnetic field. Also, the information transfer and the main information tag TF
Can be executed only during the period during which the approach-sensitive operation is continued.

The main information tag reader / writer tfRW has a built-in microcomputer, and the information transmission unit 100
0, the antenna device ANT1, and the information detection unit 1002
And a control / determination unit 1004, and operates in a transmission mode and a reception mode with the main information tag TF. In the transmission mode, information to be recorded in the main information tag TF is supplied to the main information tag TF, and in the reception mode, information reproduced from the main information tag TF is supplied. The information sending unit 1000 includes a clock generation function, a modulation function, and a power amplification function,
A clock signal of a carrier frequency and a master clock are generated, and in the transmission mode, the carrier is subjected to, for example, ASK modulation based on the transmission data supplied from the control / determination section 1004 to generate a modulated signal, which is then power-amplified and antenna-equipped with the antenna device ANT1 Drive. In the reception mode, the antenna device ANT1 is driven by amplifying the power of the carrier wave without any modulation.

The antenna ANT1 is formed of a loop antenna for both transmission and reception, and forms an electromagnetic field based on the modulated signal in the transmission mode, and forms an electromagnetic field based on the carrier wave in the reception mode. The antenna ANT2 on the main information tag TF side is inductively coupled via an electromagnetic field. The information detection unit 1002 has a function of detecting an antenna terminal voltage and a function of demodulation. Further, the control / judgment unit 100
Reference numeral 4 has an encoding / decoding function, a function of controlling the operation of the entire apparatus, and an interface function with the information processing apparatus Ipr.

In the transmission mode, the control / determination unit 1004

Drive. As a result, an electromagnetic field is formed by the carrier wave on which the command is placed, and power is supplied at the same time that the command is given to the main information tag TF by the electromagnetic field. The transmission information includes a command for reproducing and sending information recorded from the main information tag TF, and a command for recording given data in the main information tag TF and the data. Even in the reception mode, an electromagnetic field is continuously formed by an unmodulated carrier wave on which no command is carried. By this electromagnetic field, power supply to the main information tag TF is continued, and a response from the main information tag TF is detected. The response carries the reproduction information read from the main information tag TF.

Here, when the main information tag TF changes the load state of the antenna ANT2 on the main information tag TF side according to the response content or changes the power load on the main information tag TF side, the antenna ANT1 and the main information tag TF are changed. Since the antenna ANT2 on the tag TF side is in an inductively coupled state during this time, the terminal voltage of the antenna ANT1 fluctuates according to the load fluctuation on the main information tag TF side. This terminal voltage fluctuation is detected by the information detecting unit 1.
002 performs detection and demodulation, and passes it to the control / judgment unit 1004.
The control / judgment unit 1004 corrects the error, restores a response, and sends it to the information processing apparatus Ipr.

As described above, the main information tag reader / writer tfR
W transmits a command including transmission information in the transmission mode to read information from the main information tag TF or to record information. In particular, by transmitting a reproduction instruction command specifying an information type, a data item, a data address, and the like, various types of information stored in the main information tag TF are read, and further information types, data items, By transmitting a recording instruction command specifying a data address or the like and information to be recorded, it is recorded in the main information tag TF.

On the other hand, the main information tag TF is inductively coupled to the antenna apparatus ANT1 of the main information tag reader / writer tfRW using an electromagnetic field as a medium, and transmits and receives information in a non-contact manner and receives power supply by mutual induction.

A control unit Cnt1 for controlling, an encoding / decoding unit Erc connected to the control unit Cnt1, and a nonvolatile memory device M connected to the control unit Cnt1
em. The non-volatile memory device Mem functions as a storage unit.

The antenna device ANT2 is used for both transmission and reception, and is composed of, for example, a loop antenna. The demodulation means De equalizes the induced current generated in the antenna device ANT2,
Further, it is detected and demodulated to obtain information, which is supplied to the control means Cnt1. The modulating means Cm changes the load impedance (not shown) based on the response information obtained by encoding the reproduced information supplied from the control means Cnt1 and the antenna apparatus ANT2.
Modulation processing of the reflected wave by controlling to intermittently connect, or control to intermittently interrupt the load directly or indirectly connected to the power supply Pw based on response information, or modulation by response information (for example, ASK modulation) Or a configuration for feeding a carrier of another frequency to the antenna device ANT2.

More specifically, in the configuration in which the load impedance of the antenna device ANT2 is controlled based on the response information, the antenna device ANT2 which continues to receive the electromagnetic field from the main information tag reader / writer tfRW.
When a reflected wave of a carrier wave is emitted from, the reflectance of the antenna device ANT2 is controlled by switching and controlling the load impedance based on the response information, whereby the reflected wave is modulated by the above-described response information. On the other hand, in a configuration in which the power supply load is controlled based on the response information, the load applied to the power supply is switched by the load switching control based on the response information, and modulation is performed by changing the impedance of the main information tag TF in the inductive coupling state. It is configured to The impedance fluctuation on the main information tag TF side is detected as a terminal voltage fluctuation or a fluctuation in the input power of the antenna device ANT1 on the main information tag reader / writer tfRW side (external device side) in an inductively coupled state.

As described above, the information transmission / reception according to the configuration of the present embodiment is based on the induction current generated by the mutual induction when the antenna device ANT2 of the main information tag TF responds to the electromagnetic field generated by the main information tag reader / writer tfRW. The information is demodulated by processing, and then the load impedance of the antenna device ANT2 is controlled and transmitted based on the information transmitted to the main information tag reader / writer tfRW (information transmission by a reflected wave of a carrier wave) or transmitted to the main information tag reader / writer tfRW. Whether to control and transmit the load of the power supply on the main information tag TF side based on the information to be transmitted (information transmission due to impedance fluctuation),
The carrier wave of another frequency is modulated by the information transmitted to the main information tag reader / writer tfRW, and the antenna device ANT2
Or transmission (information transmission by a transmission wave of another frequency generated by the transmission function of the main information tag TF). Further, it can be realized by other principles. The other principle will be described later.

The power supply device (power supply) Pw is the antenna device A
The NT2 receives and rectifies a high-frequency induced current generated by mutual induction via an electromagnetic field, and supplies the rectified current to each unit of the apparatus as a power supply. Further, a voltage stabilizing circuit for outputting a stable DC voltage can be provided. And each part of an apparatus can operate by this supply electric power. Therefore, the main information tag TF does not need to prepare another power source such as a battery. However, it goes without saying that a configuration in which another power source such as a battery is used as the main power source or the sub power source is also possible. The clock generation unit R11 includes a frequency dividing circuit, outputs a clock signal of a carrier frequency based on the carrier wave received by the antenna 31, divides this clock signal, and operates an operation reference clock of various digital circuit units in the device. A master clock is generated and output.

As shown in the figure, an antenna device ANT2 is formed as a loop antenna on a chip serving as a base, and a semiconductor chip IC and a capacitor C are connected to the antenna device ANT2. The capacitor C adjusts the resonance frequency.

Next, the main information tag reader / writer tfRW
The principle of detecting the contents of the memory means in the main information tag TF will be described. Main information tag reader / writer tf of the present invention
Assuming that the loop antenna ANT1 on the RW side is the first antenna and the loop antenna ANT2 on the main information tag TF side is the second antenna, the first and second antennas face each other and are generated by a current flowing through the first antenna. When the magnetic field is captured by the second antenna, the magnetic field generated by the current changes in response to the change in the current flowing through the first antenna. This causes a change in the magnetic flux passing through the second antenna,
The mutual induction generates an electromotive force in the second antenna. The electromotive force V2 generated in the second antenna is proportional to the change in the current I1 of the first antenna, and is represented by V2 = M (dI1 / dt) under the tuning condition where M is a mutual inductance, and flows through the second antenna. The current I2 depends on the characteristics of the connected circuit. On the other hand, a resistance or a reactance (inductive reactance ωL or capacitive reactance 1 / ωC) can be connected to the second antenna of the main information tag TF as a load impedance, and the load impedance is intermittently connected to the second antenna. Is controlled by the content (“1” or “0”) of the memory means included in the main information tag TF.

A. First detection principle: As described above, the main information tag reader / writer tfRW is set as the primary side, and the main information tag TF inductively coupled to the main information tag reader / writer tfRW is set as the secondary side. When the impedance is Z, it can be treated as the inductively coupled four-terminal network shown in FIG. Here, the impedance Zie measured on the primary side is calculated as follows. is the angular frequency, the inductance of the antenna ANT1 of the main information tag reader / writer tfRW is L1, and the electromotive force is V
1, the current is I1, and the antenna ANT of the main information tag TF
2 is L2, the electromotive force is V2, and the current is I
2. Further, assuming that the mutual inductance between the antennas ANT1 and ANT2 is M, the induced electromotive force V
1 is V1 = jω * L1 * I1 + jω * M * I2, and the induced electromotive force V2 is V2 = jω * M * I1 + jω * L2 * I2. Here, since the direction of the current I2 is reversed, V2 = −Z * I2.

From the above, the main information tag reader / writer tfR
The impedance Zie on the W side is jω * (L1−M ** 2 / L2) as the first term, with the symbol “**” being the square.
And jω * (M ** 2) * Z / L2 * as the second term
(Z + jω * L2). Here, u2 = L2 / jω * (M ** 2) Further, if the second term is modified as u3 = (L2 ** 2) / Z * (M ** 2), it becomes 1 / (u2 + u3). . Therefore, if the first term is u1, the impedance Zie of the main information tag reader / writer tfRW
Becomes Zie = u1 + 1 / (u2 + u3). As a result, an equivalent circuit of the inductive coupling four-terminal network shown in FIG. 4 can be shown as in FIG.

The impedance Z on the main information tag TF side is
If the circuit is controlled to have an infinite impedance according to the contents of the memory means (either "1" or "0", for example, "1"), u3 = (L2 ** 2) / Z * The term (M ** 2) becomes infinitesimal, and the state of "1" in the memory means is observed on the main information tag reader / writer tfRW side as impedance Zie1 = jω * L1. On the other hand, when the impedance Z on the main information tag TF side is set to zero impedance according to the contents of the memory means (either "1" or "0", for example, "0"), 1 / (u2 + u3) ) Becomes infinitesimal, and the state of “0” of the memory means is observed as impedance Zie0 = jω * (L1−M ** 2 / L2) on the main information tag reader / writer tfRW side. This is expressed as Zie0 = jω * L1 * (1-k ** 2) using the coupling constant kk ** 2 = M ** 2 / L1 * L2 of the antennas ANT1 and ANT2. As described above, the state of “1” or “0” of the memory means on the main information tag TF side depends on the above-described different impedance value Zie on the main information tag reader / writer tfRW side.
By observing as 1, Zie0, the state of "1" or "0" of the memory means can be easily detected.

Further, by changing the impedance Z on the main information tag TF side to any different value between zero and infinity, different impedance values Zie corresponding to the respective values can be observed. In this way, the primary side (main information tag reader / writer tfRW) according to the load Z on the secondary side (main information tag TF side) by mutual guidance.
Since the impedance Zie of the primary side changes, by detecting the change of the primary side impedance Zie,
The state on the main information tag TF side can be detected.

B. Second detection principle: Next, by supplying power to the above inductively coupled four-terminal network only from the primary side, the entire inductively coupled four-terminal network is loaded into the power supply circuit of the main information tag reader / writer tfRW. And the supplied power fluctuates with the change in the impedance Zie of the load. Therefore, the main information tag reader / writer tfRW detects the fluctuation of the supplied power, whereby the contents of the memory means of the main information tag TF can be detected.

C. Third detection principle: The main information tag reader / writer tfRW is connected to the antenna ANT2 on the main information tag TF side.
When an electromagnetic wave is incident from the antenna ANT1 on the side and an induced current is generated on the side of the main information tag TF by electromagnetic induction, the electromagnetic wave is emitted again from the antenna ANT2. This is due to back scattering or reflection of the electromagnetic wave by the antenna ANT2. , Reflected) on the main information tag reader / writer tfRW side. In addition, since this reflectance depends on the antenna impedance of the main information tag TF, and the antenna impedance depends on the state of the circuit, the main information tag reader / writer tfRW knows the state of the circuit of the main information tag TF from the observed reflected wave. be able to. Therefore, by adopting a configuration in which the antenna impedance of the main information tag TF is changed in accordance with the contents of the memory means, the main information tag reader / writer tfRW detects the contents of the memory means of the main information tag TF based on the observed reflected wave. be able to.

The second or third detection principle will be further described. There are cases where the resonance frequency of the antenna ANT2 changes and shifts due to a change in the state of the main information tag TF, and cases where the resonance frequency does not change. The current in the resonant circuit is a function of the impedance Z,
Is a function of resistance R, inductance L, and capacitance C. For example, when the equivalent circuit of the antenna resonance circuit is approximated by the series connection of the resistance R, the inductance L, and the capacitance C, the impedance Z is the square of the resistance R, the inductive reactance ωL, and the capacitive reactance 1 /.
It is the root of the sum of the square of the difference of ωC. Q of this resonance circuit
The value (quality factor) is 2 of the absolute value of the induced current.
The peak value at the resonance point (resonance frequency ω 0) of the power characteristic curve is determined by the peak value and the half value width. Therefore, the Q value depends on the resistance R, the inductance L, and the capacitance C. The square of the absolute value of the induced current is obtained as a product of a conjugate complex number in a complex number representation. On the other hand, the resonance frequency ω0 of this equivalent circuit is the reciprocal of the root of the product of the inductance L and the capacitance C, and thus depends on the inductance L and the capacitance C and does not depend on the resistance R. At the time of resonance, the impedance Z becomes a pure resistance, has a minimum value, and the resonance current has a maximum value.

Based on the above characteristics, the antenna ANT2
When the resistance R of the resonance circuit on the side is changed in accordance with the contents (“1” or “0”) of the memory means, the resonance frequency ω0 does not move, and the peak value and half of the current at the resonance point are not changed. The value width (and thus the Q value) changes. This change can be detected as a change in the transmission power on the antenna ANT1 side that applies energy to the antenna ANT2 side via electromagnetic waves under inductive coupling as described above. Therefore, the content of the memory means ("1" or "0") can be detected based on the detection result.

On the other hand, when the load having the inductance L and the capacitance C is connected to and disconnected from the antenna ANT2 in accordance with, for example, the contents (“1” or “0”) of the memory means, the resonance circuit on the antenna ANT2 side is used. Of the inductive reactance ωL or the capacitive reactance 1 / ωC in the impedance of
Shift to Therefore, in this case, the main information tag TF
In the side antenna ANT2, the re-radiated power increases due to an increase in the standing wave ratio of the current due to the electromagnetic wave of the frequency ω0 emitted from the main information tag reader / writer tfRW, while the power supplied from the antenna ANT2 to the load increases. As a result, the antenna ANT2 functions as a reflection device of the electromagnetic wave of the frequency ω0 emitted from the main information tag reader / writer tfRW, and emits a reflected wave. The main information tag reader / writer tfRW can detect the contents of the memory means of the main information tag TF by detecting the reflected wave. Alternatively, the main information tag reader / writer tf
The RW shifts the frequency ω0 of the emitted electromagnetic wave to ω0 ′ when the resonance frequency shifts according to the contents of the memory means on the main information tag TF side as described above, and By detecting absorption, the main information tag T
The contents of the memory means of F can be detected.

D. Fourth detection principle: Each of the above-mentioned principles is applied to the main information tag reader / writer tfRW on the primary side so as to be handled as an inductively coupled four-terminal network.
F, and detects the contents of the memory means in the main information tag TF in a state where the main information tag TF is inductively coupled to the main information tag reader / writer tfRW by mutual induction. It did not transmit information by emitting electromagnetic waves. On the other hand, the main information tag TF emits an electromagnetic wave carrying information by itself, thereby allowing the main information tag reader / writer tfRW to receive the electromagnetic wave, thereby transmitting the information to the main information tag reader / writer tfRW.

In this case, the main information tag TF has an independent electromagnetic wave emitting function, and uses the power supplied from the main information tag reader / writer tfRW, or prepares a separate power supply and directs it to the main information tag reader / writer tfRW. Launches electromagnetic waves independently. Main information tag reader / writer tfRW
By receiving this electromagnetic wave and extracting information, the contents of the memory means of the main information tag TF can be obtained.

The present invention can be configured to apply at least any of the above principles.

If the related information iref does not exist, the process ends.

If the related information iref of the article exists, it is checked whether the related information iref is the first type information isj1 or the second type information isj2 (step S63), and the second type information isj2 is determined. If this is the case, it is read out and sent to the main information tag information management means M2 together with this second type information isj2 and an index indicating that it is the second type information. When the main information tag information management means M2 drives the main information tag reader / writer tfRW based on the information and instructs recording in the main information tag TF as the second type information isj2, the main information tag reader / writer tfRW causes the second type The information isj2 is written into the storage unit of the main information tag TF (step S6)

Based on this, the main information tag reader / writer tfRW is driven to instruct recording in the main information tag TF as the first type information isj1, and the main information tag reader / writer tfRW stores the first type information isj2 in the main information tag TF. Writing to the means (step S65). This writing is performed by the main information tag reader / writer tfRW by the operator.
This is executed while an approaching operation such as “Holding” is performed on F.

As described above, when the information for specifying the article Mat is obtained from the bar code mark attached to the article Mat, based on the information, the related information ire of the article Mat is obtained.
f is searched from the file FL, and the related information ire
f is taken out and transcribed to the main information tag TF attached to the article Mat. In addition, the above operation is automatically executed, and there is no need for the operator to input data for operation instruction on the way. Therefore, the processing is performed quickly, the required time can be reduced, and no inconvenience due to erroneous data input does not occur. In addition, the operation is an operation of approaching the bar Mat reader bcR to the article Mat (holding operation).

Here, the operator may operate so as to continue the approaching operation (holding operation) from the reading by the barcode reader bcR until the writing by the main information tag reader / writer tfRW is completed. This eliminates the need for a plurality of approaching operations, further simplifies the operation, and enables efficient processing.

Similarly, the bar code reader bcR and the main information tag reader / writer tfRW are placed at predetermined positions,

In particular, although not shown, the barcode reader bcR and the main information tag reader / writer tfRW are fixed at predetermined positions, and the article Mat is placed on a belt conveyor and moved to approach the barcode reader bcR and the main information tag reader / writer tfRW. It is also possible to adopt a configuration in which it is performed. According to this configuration, a large number of articles Mat can be processed continuously, and more efficient initial issuance of the main information tag TF becomes possible. In the case of this automatic configuration, the reading of the barcode, the reading from the file FL, and the transfer to the main information tag TF are all completed while the article Mat is approaching, that is, until the above-described processing is completed. It is preferable to set the moving speed of the belt conveyor and the installation positions of the barcode reader bcR and the main information tag reader / writer tfRW so that the approach operation is continued.
