A print head 305 that performs predetermined printing in the predetermined area, an antenna (communication means) 306 and a high-frequency circuit (communication means) 301 for transmitting and receiving information by wireless communication with the RFID circuit element To. A control circuit 302 connected to the CPU 10 and the like via the output interface 310, and tag tags The tag tape 303, which has finished printing on the tape 303 and writing the information on the RFID circuit element To, is cut into a predetermined length to form the tag labels Tb and Th, and the print head 305 is provided opposite to the cutter 307. And a conveying device (conveying means) 309 that conveys the tag tape 303 under the control of the control circuit 302.

  The high-frequency circuit 301 and the control circuit 302 included in the tag label creating unit 11 are not described in detail, but have substantially the same functions as the RF communication control unit 17 and the CPU 10 of the register 3 described above. Access information (including at least a tag ID as identification information) to the IC circuit unit 150 of the element (the RFID tag circuit element provided in the fixed price tag label Tb or the RFID tag circuit element provided in the discount tag label Th) To is stored in the database 6. The information is acquired and transmitted to the RFID circuit element To via the device-side antenna 306, and information is written to the IC circuit unit 150 of the RFID circuit element To.

  FIG. 5 is a block diagram showing an example of a functional configuration of the RFID circuit element To provided in common to the tag labels Tb and Th.

  In FIG. 5, the RFID circuit element To includes a planar antenna 4 of the register 3 as described above, an antenna 151 that performs non-contact signal transmission and reception using a high frequency such as a UHF band and a microwave, and the antenna 151. And an IC circuit unit 150 connected thereto.

  The IC circuit unit 150 includes a rectifying unit 152 that rectifies the carrier wave received by the antenna 151 that is the tag side antenna, and a power source unit 153 that accumulates the energy of the carrier wave rectified by the rectifying unit 152 and serves as a driving power source. A clock extraction unit 154 that extracts a clock signal from the carrier wave received by the antenna 151 and supplies the clock signal to a control unit (described later) 157; a memory unit 155 that functions as an information storage unit that can store a predetermined information signal; A modulation / demodulation unit 156 connected to the antenna 151, and a control unit 157 for controlling the operation of the RFID circuit element To through the rectification unit 152, the clock extraction unit 154, the modulation / demodulation unit 156, and the like. Yes.

  The modulation / demodulation unit 156 demodulates the communication signal received from the planar antenna 4 of the register 3 received by the antenna 151 and modulates the carrier wave received from the planar antenna 4 based on the return signal from the control unit 157. Then, it is retransmitted as a reflected wave from the antenna 151.

  The control unit 157 interprets the received signal demodulated by the modulation / demodulation unit 156, generates a return signal based on the information signal stored in the memory unit 155, and performs basic control such as returning by the modulation / demodulation unit 156. Execute proper control.

  The clock extraction unit 154 extracts a clock component from the received signal and extracts the clock to the control unit 157, and supplies a clock corresponding to the speed of the clock component of the received signal to the control unit 157.

  The memory unit 155 stores at least tag IDs for individually identifying the tag labels Tb and Th, and the tag IDs are information that can be distinguished between the fixed price tag label Tb and the discount tag label Th. It has become. Corresponding to this, the register 3 can distinguish and detect the fixed price tag label Tb and the discount tag label Th.

  6A and 6B are diagrams showing an example of the overall schematic structure of the tag labels Tb and Th. FIG. 6A is a top view of the regular price label Tb, and FIG. 6B is a top view of the discount tag label Th. In FIG. 6A and FIG. 6B, the tag labels Tb and Th include, for example, a substantially sheet-shaped label main body 149 and a RFID circuit element To disposed on the label main body 149 as described above. I have.

  As shown in FIG. 6A, on the front side (upper surface) of the label main body 149 of the price tag label Tb, corresponding price printing information Ab (in this example, “rice: 300 yen”) Rb is printed. Is provided. Further, as shown in FIG. 6B, corresponding discount printing information (in this example, “discount: 30 yen”) Rh is printed on the front side (upper surface) of the label main body 149 of the discount tag label Th. A discount printing area (printing area) Ah is provided. In addition, printing of these fixed price printing information Rb and discount printing information Rh is not indispensable, and when a label printed with a fixed price, a product name, etc. is affixed, it is not a letter but a figure, code, or simple color. It may be a paint (can be colorless) or a pattern.

  As described above, the most significant feature of the present embodiment is that, in addition to attaching the fixed price tag label Tb for storing the tag ID associated with the product 2 to obtain the fixed price from the database 6 to the product 2, After a predetermined time has elapsed (or temporarily), a discount tag label Th corresponding to information for changing the price to change (price reduction or price increase) is affixed to the product 2, and processing corresponding to this is performed in the register 3. Is to do. Hereinafter, the details will be described in order.

  First, information stored in the fixed price tag label Tb and discount tag label Th in the example of the present embodiment, and information processing and accounting calculation performed by the register 3 based on the information will be described.

  FIG. 7 is a diagram conceptually showing the flow of information processing and accounting calculation when only the regular price tag label Tb is attached to the product 2. In FIG. 7, only the article tag ID (tag identification information) stored in the fixed price tag label Tb is detected from the planar antenna 4 and the RF communication control unit 17 of the register 3. The list price information (300 yen in this example) corresponding to the ID is acquired from the database 6 via the communication network NW, and the list price is directly accounted for as the sales price of the single product. This is the accounting calculation for product 2 in the normal case.

  Then, for example, when a discount tag label Th is further attached to the product 2 by a limited time sale service or a disposal service before closing, as shown in FIG. 8, the planar antenna 4 and the RF communication control unit 17 of the register 3 are used. To the article tag ID stored in the fixed price tag label Tb and the change tag ID (information corresponding to the changed information) stored in the discount tag label Th are detected. The register 3 obtains the list price information corresponding to the article tag ID and the discount price information corresponding to the change tag ID (30 yen in this example) from the database 6, and based on these, the list price information is obtained from the discount price information. The sales price of a single item is calculated and accounted for as a change process.

  The association between the article tag ID and the fixed price information and the association between the change tag ID and the discount amount information are constructed by inputting in advance into the database 6 by a data manager or the like. .

  FIG. 9 is a flowchart showing a control procedure executed by the CPU 10 of the register 3. In FIG. 9, for example, when the start switch 31 (see FIG. 1) in the operation unit 14 is pressed, this flow is started.

  First, in step S5, in this example, it is determined whether or not the accounting switch 33 (see FIG. 1) in the operation unit 14 of the register 3 is pressed. If the accounting switch 33 is pressed to perform an accounting operation by the operator, the determination is satisfied, and after performing the accounting process of step S100, the process proceeds to step S10. On the other hand, if the accounting switch 33 has not been pressed, the determination is not satisfied and the routine goes directly to step S10.

  In step S10, it is determined whether the regular price tag label creation switch 34 (see FIG. 1) is pressed. If the operator presses the price tag label creation switch 34 to create the price tag label Tb, the determination is satisfied, and after performing the price tag label creation processing (normal mode) in step S200, the process proceeds to step S15. On the other hand, if the regular price tag label creation switch 34 has not been pressed, the determination is not satisfied and the routine goes directly to step S15.

  In step S15, it is determined whether or not the discount tag label creation switch 35 (see FIG. 1) is pressed. If the operator has pressed the discount tag label creation switch 35 to create the discount tag label Th, the determination is satisfied, and the step after the discount tag label creation processing (change tag mode) in step S300 is performed. Move on to S20. On the other hand, if the discount tag label creation switch 35 has not been pressed, the determination is not satisfied and the routine goes directly to step S20.

  In step S20, it is determined whether or not the end switch 32 (see FIG. 1) is pressed. If the operator has pressed the end switch 32 to end the operation at the register 3, the determination is satisfied and the flow ends. On the other hand, when the end switch 32 is not pressed, the determination is not satisfied, that is, it is considered that the operation in the register 3 is still performed, and the process returns to step S5 and the same procedure is repeated.

  FIG. 10 is a flowchart showing a detailed procedure of the accounting process executed by the CPU 10 of the register 3 in step S100. In FIG. 10, first, in step S105, the total amount S of sales for each customer is reset to zero.

  In step S110, it is determined whether the tag labels Tb and Th are detected from the planar antenna 4 of the register 3. A method for detecting the tag labels Tb and Th will not be described in detail here, but a question command signal for requesting a response to all the tag labels Tb and Th, such as a “Scroll All ID” signal, is generated by a known technique. All the response signals transmitted from the planar antenna 4 via the communication control unit and transmitted by the tag labels Tb and Th are received by the same planar antenna 4. At this time, the detection of the tag labels Tb and Th is continued for a predetermined time range after receiving the first response signal so that the plurality of tag labels Tb and Th attached to one product 2 can be detected. In step S110, a loop is made until at least one response signal is received, and the question signal is repeatedly transmitted.

  Next, the process proceeds to step S115, and it is determined whether or not the article tag ID is included in the response signal from the tag labels Tb and Th detected in step S110. A fixed price tag label Tb should always be affixed to one product 2 and the product tag ID should be detected. If the product tag ID is not detected and only other response signals are detected, the determination is made. Is not satisfied, that is, the fixed price tag label Tb has been taken from the product 2 or the detection of the fixed price tag label Tb is considered to have failed, and error processing such as outputting a signal for displaying an error on the display unit 15 is performed in step S120. Then, this accounting process flow is terminated. On the other hand, if the article tag ID is detected, the determination is satisfied, and the routine goes to the next Step S125.

  In step S125, based on the detected article tag ID, a search is performed by accessing the database 6 (abbreviated as DB in the figure, the same shall apply hereinafter), and list price amount information (in the figure and In the following description, the list price is abbreviated), and the process proceeds to the next step S130.

  In step S130, it is determined whether or not the change tag ID is included in the response signal from the tag labels Tb and Th detected in step S110. If the change tag ID is not included, the determination is not satisfied, that is, it is regarded that there is no change such as discount or price increase in the product 2 and the process is not performed without performing the change processing of step S135 and step S140. The process moves to step S145. On the other hand, when the change tag ID is detected, the change processing of the next step S135 and step S140 is performed.

  In the next step S135, the database 6 is accessed and searched based on the detected change tag ID, and the discount amount information indicating the discount amount of the corresponding product 2 (the discount amount in the figure and the following description). Is omitted from the database 6, and in the next step S140, the discount amount is subtracted from the list price acquired in step S125 (in the case of a price increase, it is calculated by adding). In this example, the discount amount is set as an absolute amount that is directly deducted from the list price. However, for example, the discount amount may be set as a percentage of the list price (for example, 10% discount). In this case, the discount amount is calculated at the ratio and is subtracted from the list price. Further, this discount amount may be set so as to change with the passage of time. In this case, although not shown in particular, the discount amount changed with the passage of time by providing the database 6 with a clock function. Make information available.

  Next, the process proceeds to step S145, where the display control signal is output to the display unit 15 to display the list price at that time (the sales price with the discount amount if discounted). Further, the print control signal may be output to the receipt printing unit 16 so that the regular price (sales price) at that time is printed on the receipt 18. At this time, if the item and discount price of the product 2 are also displayed and printed, the sales price of the single product becomes clear.

  Next, the process proceeds to step S150, and the list price (sales price) at that time is added to the total price S, and then the process proceeds to next step S155.

  In step S155, it is determined whether the total switch 36 (see FIG. 1) is pressed. If the total switch 36 has not been pressed, the determination is not satisfied, that is, it is considered that there is another product 2 to be accounted for by the same customer, and the process returns to step S110 and the same procedure is repeated. On the other hand, when the total switch 36 is pressed, the determination is satisfied, that is, it is considered that the accounting for all the products 2 purchased by the same customer is finished, and the display unit 15 controls in the next step S160. A signal is output to display the total amount S of the sales amount of all the products 2 (and the total amount S is printed on the receipt 18), and this flow is finished.

  FIG. 11 is a flowchart showing the detailed procedure of the regular price tag label generation process executed by the CPU 10 of the register 3 in step S200. In FIG. 11, first, in step S205, the list price to be created operated by the operation unit 14 of the register 3 shown in FIG. 1 (or the operation unit of another PC terminal (not shown) connected via the communication network NW). Input (recognize) the item of the product 2 to be attached with the tag label Tb. In the operation input in the operation unit, the name of an item may be input as it is from a keyboard or the like, or for example, a menu listing all items is displayed on the display unit 15 and selected from there. You may do it.

  Next, the process proceeds to step S210, the database 6 is accessed and searched based on the product item input in step S210, the corresponding article tag ID and the regular price printing information Rb are obtained from the database 6, and the next step S215 is performed. Move.

  In step S215, a command signal is output to the control circuit 302 of the tag label producing unit 11 (see FIG. 4), and the article tag acquired in step S210 above with respect to the RFID circuit element To provided in the tag tape 303. The ID is written and the fixed price printing information Rb is printed on a predetermined area (fixed price printing area Ab) on the surface of the label main body 149 (tag tape 303).

  In the next step S220, a command signal is output to the control circuit 302 of the tag label producing unit 11, the tag tape 303 is cut by the cutter 307 of the tag label producing unit 11, and the fixed price tag label provided with one RFID circuit element To. Tb is created and this flow ends.

  FIG. 12 is a flowchart showing the detailed procedure of the discount tag label creation process executed by the CPU 10 of the register 3 in step S300. The control procedure shown in FIG. 12 is substantially the same as the flowchart of the regular price tag label generation process shown in FIG. 11, and only the procedure that is mainly different will be described below.

  12, first, in step S305, a commodity item is input in the same manner as in step S205 in FIG. 11, and in the next step S310, a change tag corresponding to the input commodity item in the same manner as in step S210 in FIG. ID and discount print information Rh are acquired from the database 6. The above-described discount amount information that is the basis of the discount print information Rh is obtained, for example, when the CPU 10 of the register 3 outputs a display signal for displaying the change setting screen to the display unit 15 to the display unit 15. Then, the contents of the discount amount information together with the list price information are displayed on the display unit 15 (= change setting screen), and the user sets various information contents in advance through the operation unit 14 while viewing the change setting screen. You may make it keep.

  At this time, the product 2 may be selected and specified by menu selection on the operation unit 14, and the above-mentioned various information may be set based on the selection. For example, the amount itself may be directly input from the operation unit 14 as the amount information. It may be set to 6.

  In the next step S315, a command signal is output to the tag label producing unit 11 in the same manner as in step S215 in FIG. 11, and the obtained changed tag ID is written to the RFID circuit element To provided in the tag tape 303. The discount print information Rh is printed in a predetermined area (discount print area) on the surface of the label main body 149 (tag tape 303).

  In the next step S320, the tag tape 303 is cut to create a discount tag label Th as in step S220 of FIG. 11, and this flow is terminated.

  In the above, step S110, step S125 and step S135 in the flow of FIG. 10 correspond to the information acquisition means described in each claim, step S140 in the flow of FIG. 10 corresponds to the change processing means, and step in the flow of FIG. S315 corresponds to the writing control means. Further, step S10 and step S15 in the flow of FIG. 9 correspond to mode switching means.

  As described above, in the present embodiment, the list price information relating to the product 2 to which the discount tag label Th is attached is attached to the IC circuit unit 150 of the RFID circuit element To provided in the discount tag label Th. The change tag ID corresponding to the discount amount information to be changed only in the register 3 is stored and held (note that the discount amount information itself may be written into the IC circuit unit 150 and stored and held. ).

  Then, the register 3 has a list price information related to the product 2 associated with the list tag label Tb based on the article tag ID stored and held in the IC circuit section 150 of the RFID circuit element To provided in the list tag Tb. And a control procedure for acquiring the change tag ID stored in the IC circuit unit 150 of the RFID circuit element To of the discount tag label Th (steps S110, S125 and S135 in the flow of FIG. 10). ), The discount amount information is acquired based on the change tag ID, and the control procedure (step S140 in the flow of FIG. 10) of changing the list price information using the discount amount information is performed.

  As a result, there is no need to modify the list price information stored in the database 6 corresponding to the original article tag ID, so that the list price information in the database 6 is corrected and then restored again. The general user can substantially change the list price information by an easy and simple method without the need for bothersomeness and advanced knowledge for operating the database 6.

  In the present embodiment, in particular, the fixed price tag label Tb and the discount tag label Th itself used as described above can be created by the tag label creating unit 11 provided in the register 3. In other words, the tag label creating unit 11 conveys the tag tape 303 with a conveying device, and the RFID tag circuit element is connected to the IC circuit unit 150 of the RFID tag circuit element To provided in the tag tape 303 via the antenna 306. A control procedure (step S315 in the flow of FIG. 12) for writing the change tag ID corresponding to the discount amount information for changing the list price information related to the product 2 assumed in advance to To is performed, and the RFID circuit Tag labels Tb and Th are created using the element To.

  The information stored in the RFID circuit element To of the discount tag label Th may store the discount amount information itself, not the change tag ID for acquiring the discount amount information. In this case, the product tag ID stored in the fixed price tag label Tb and the value stored in the discount tag label Th from the planar antenna 4 of the register 3 as shown in the flow of information processing and accounting calculation shown in FIG. The discount amount information is detected, and the register 3 can change the discount amount information with the discount amount information immediately after acquiring the list price amount information from the database 6 based on the article tag ID.

  In this embodiment, in particular, the discount label print area Ah in which the discount print information Rh related to the discount amount information is printed on the label main body 149 of the discount tag label Th is provided. The user can clearly visually recognize what change function the discount tag label Th has by simply looking at the printout.

  In this embodiment, particularly, the register 3 is within a predetermined time range before and after the time when the change tag ID corresponding to the discount amount information is acquired from the IC circuit unit 150 of the RFID tag circuit element To of the discount tag label Th. The price information is acquired based on the article tag ID of the price tag label Tb. As described above, the fixed price information acquired within the predetermined time range before and after is regarded as the fixed price information of the product 2 that is assumed to be changed in the discount tag label Th, and is changed using the discount price information. . As a result, the RFID tag circuit element To of the discount tag label Th does not necessarily need to store and hold the article tag ID and the list price information, and the storage capacity can be reduced (or can be used for another purpose). It is not necessary to perform collation on the third side, and the configuration and control contents can be simplified and processed quickly.

  Further, in this embodiment, in particular, the tag label creating unit 11 writes the change tag ID corresponding to the discount amount information, the discount tag label creation processing according to the flow of FIG. 12, and the change tag corresponding to the discount amount information. A control procedure (step S10 and step S15 in the flow of FIG. 9) for switching between the price tag label creation processing according to the flow of FIG. 11 in which no ID is written is performed. Thereby, the user selectively switches the generation processing of the tag labels Tb and Th according to the use and needs, and thereby the discount tag label provided with the change tag ID corresponding to the discount amount information in the RFID circuit element To. Since both the Th and the fixed price tag label Tb that does not include the change tag ID corresponding to the discount amount information in the RFID circuit element To can be created by the same tag label creating unit 11, the convenience is improved.

  In this embodiment, in particular, the CPU 10 of the register 3 outputs to the display unit 15 a display signal for displaying a change setting screen for setting the contents of the fixed price amount information and the discount amount information on the display unit 15. The contents of the list price information and the discount price information are displayed on the change setting screen of the display unit 15, and the user can set various information contents on the change setting screen, thereby changing the list price information. The operation of creating the discount tag label Th for performing can be performed more easily and smoothly.

  Whether or not the discount tag label creation processing is to be performed on the label creation unit 11 of the register 3 according to this embodiment depends on whether or not the discount tag label creation switch 35 of the operation unit 14 is pressed in step S15 in the flow of FIG. However, the present invention is not limited to this. For example, the determination may be made based on whether or not the article tag ID of the regular price tag label Tb is detected from the planar antenna 4. In other words, instead of pressing the discount tag label creation switch 35, the discount tag label creation process can be started by detecting the product tag ID by passing the price tag label Tb of the product 2 to be discounted through the area near the flat antenna 4. In this case, step S305 is omitted in the flow of FIG. 12, and in step S310, a change tag ID and discount print information set in advance in association with each other are acquired from the database 6 (step S310). (It is not particularly shown, and the subsequent control procedure is the same).

  As described above, when the product tag ID is detected from the RFID circuit element To of the regular price tag label Tb related to the predetermined product 2 through the RF communication control unit 17 and the planar antenna 4 connected to the tag label creating unit 11, When the change tag ID corresponding to the product 2 is acquired from the database 6 based on the article tag ID and input to the tag label creating unit 11 to create the discount tag label Th having the corresponding change tag ID, The discount tag label Th that stores the change tag ID corresponding to the product 2 can be easily created, and the convenience for the user can be further improved.

  In addition, this embodiment is not restricted above, A various deformation | transformation is possible in the range which does not deviate from the meaning and technical idea. Hereinafter, such modifications will be described in order.

(1-1) When storing the product tag ID in the discount tag label Th In the first embodiment, only the change tag ID corresponding to the discount amount information is stored in the discount tag label Th. The product tag ID that can identify the item of the product 2 is also stored in the discount tag label Th together with the change tag ID.

  FIG. 14 is a flow of information processing and accounting calculation when a fixed price tag label Tb for storing an article tag ID and a discount tag label Th for storing an article tag ID and a change tag ID are attached to a product (article) 2. FIG. In FIG. 14, the first article tag ID stored in the fixed price tag label Tb, the second article tag ID and the change tag ID stored in the discount tag label Th are detected from the planar antenna 4 of the register 3. It will be.

  Then, the register 3 collates the first product tag ID and the second product tag ID, and determines whether or not they match (whether they are tag IDs corresponding to the same product item). If they do not match, it is assumed that the discount tag label Th does not correspond to the product 2 and error processing is performed. If they match, the list price information corresponding to the first article tag ID and the discount price information corresponding to the change tag ID are acquired from the database 6 respectively, and based on these, the price information is changed by the discount price information. In this way, the sales price of a single item is calculated and accounted for.

  When each tag ID is detected, it can be recognized that the first article tag ID is detected from the fixed price tag label Tb and the second article tag ID is detected from the discount tag label Th. Alternatively, the data structure may be individually identified while holding the identification information of the product 2 by a separate method, or a time difference may be provided in the detection timing.

  FIG. 15 is a flowchart showing a detailed procedure of the accounting process executed by the CPU 10 of the register 3 in the present modification, and corresponds to FIG. 10 in the first embodiment. The flow in FIG. 15 is roughly the same as the flow in FIG. 10, and is basically different in that steps S137 and S139 are added after step S135 in the flow in FIG. In step S115, it is determined that the first article tag ID is detected. In step S125, the list price information corresponding to the first article tag ID is acquired from the database 6. Hereinafter, the different procedures will be described.

  In FIG. 15, after the discount amount information corresponding to the change tag ID is acquired from the database 6 in step S135, the process proceeds to step S137, and the second product tag ID is included in the response signal detected in step S110 from the tag labels Tb and Th. It is determined whether or not. In this example, the second item tag ID to be checked against the first item tag ID stored in the fixed price tag label Tb should be detected from the discount tag label Th, and if the second item tag ID is detected. If not, the determination is not satisfied, that is, it is considered that a defective or inappropriate discount tag label Th is affixed to the product 2, the error process of step S120 is performed, and the flow of this accounting process is terminated. On the other hand, if the second article tag ID is detected, the determination is satisfied, and the routine goes to the next Step S139.

  In step S139, it is determined whether or not the first product tag ID detected from the fixed price tag label Tb matches the second product tag ID detected from the discount tag label Th, that is, the two product tag IDs are set to the same product 2. It is determined whether or not the corresponding identification information. If the two product tag IDs do not match, that is, if each product tag ID is tag identification information corresponding to a different product 2, the determination is not satisfied, that is, the price tag label Tb and the value for the same product 2 It is considered that one of the tag tags Th that is not supported is attached to the wrong label, and the error process of step S120 is performed, and this accounting process flow is ended. On the other hand, if the two article tag IDs match, the determination is satisfied, and the routine goes to the next Step S140. Other procedures are the same as those in FIG.

  In addition, the price tag label creation process performed in this modification example is the flowchart of FIG. 11 in the first embodiment, and the product tag ID acquired in step S210 and the tag ID written in step S215 are respectively the first product tag ID. Other than that is the same.

  Further, the discount tag label creation process performed in the present modification example is the flowchart of FIG. 12 in the first embodiment, and the tag IDs acquired in step S310 are two of the change tag ID and the second article tag ID. The tag IDs written in step S315 are also the change tag ID and the second article tag ID, and the others are the same.

  In the above, step S139 in the flow of FIG. 15 corresponds to the collating means.

  In the present variation configured as described above, in the register 3, step S110 in the flow of FIG. 15 acquires the second article tag ID stored and held in the IC circuit unit 150 of the discount tag label Th, and FIG. In step S140 in the flow, based on the second item tag ID related to the discount tag label Th, the list price information acquired based on the first item tag ID of the list tag label Tb is changed using the discount amount information.

  At this time, in particular, in step S139, the matching between the first item tag ID of the regular price tag label Tb and the second item tag ID of the discount tag label Th is collated, and only when it is determined that the matching is recognized, The list price information acquired based on the first article tag ID of the list tag Tb is changed. As a result, even if the user mistakenly acquires the list price information of the product 2 that is not assumed to be the target of changing the discount tag label Th and tries to change it using the discount price information related to the discount tag label Th, the first article If the tag ID and the second article tag ID are not matched properly, the change cannot be made.

(1-2) When the price tag information Th is stored in the discount tag label Th The price tag information may be stored in the discount tag label Th together with the change tag ID.

  FIG. 16 shows the flow of information processing and accounting calculation when the price tag label Tb for storing the product tag ID and the discount tag label Th for storing the price price information and the change tag ID are attached to the product (article) 2. FIG. In FIG. 16, from the planar antenna 4 of the register 3, the article tag ID stored in the list tag label Tb and the second list price information (changed information, price information of the article) stored in the discount tag label Th. Then, the change tag ID is detected.

  The register 3 obtains the first list price information corresponding to the article tag ID and the discount price information (item price change information) corresponding to the change tag ID from the database 6, respectively, and then the first list price information and the first price information. 2 Check the list price information and determine whether or not they match. If they do not match, the discount tag label Th is regarded as not corresponding to the fixed price tag label Tb, and error processing is performed. If they match, the selling price of the single product is calculated and accounted for by changing the first list price information (or the second list price information) according to the discount price information.

  FIG. 17 is a flowchart showing a detailed procedure of the accounting process executed by the CPU 10 of the register 3 in this modification, and corresponds to FIG. 10 in the first embodiment. The flow in FIG. 17 is roughly the same as the flow in FIG. 10, and is basically different in that steps S137A and S139A are added after step S135 in the flow in FIG. Hereinafter, the different procedures will be described.

  In FIG. 17, after the discount amount information corresponding to the change tag ID is acquired from the database 6 in step S135, the process proceeds to step S137A, and the second list price information is included in the response signal from the tag labels Tb and Th detected in step S110. It is determined whether or not. In this example, the second list price information to be checked against the first list price information corresponding to the article tag ID stored in the list tag label Tb should be detected from the discount tag label Th. When the list price information is not detected, the determination is not satisfied, that is, it is considered that a defective or inappropriate discount tag label Th is attached to the product 2, and an error process of step S120 is performed, and this accounting process is performed. End the flow. On the other hand, if the second list price information is detected, the determination is satisfied, and the routine goes to the next Step S139A.

  In step S139A, it is determined whether or not the first list price information acquired from the price tag label Tb and the second list price information detected from the discount tag label Th match. If the two fixed price amounts do not match, that is, if each fixed price amount information is a different fixed price amount, the determination is not satisfied, that is, one of the fixed price tag label Tb and the discount tag label Th is not set for the same product 2. It is considered that the wrong correspondence is attached, the error process of step S120 is performed, and the flow of this accounting process is terminated. On the other hand, if the two list prices match, the determination is satisfied, and the routine goes to the next Step S140.

  In step S140, the discount is calculated by subtracting the discount amount from the first list price (or the second list price), and in step S145, the first list price (second list price) is displayed on the display unit 15. In S150, the first fixed price (second fixed price) is added to the total price S. Other procedures are the same as those in FIG.

  Further, the discount tag label creation process performed in the present modification is the flowchart of FIG. 12 in the first embodiment. In step S310, the second list price information, the change tag ID, and the discount print information corresponding to the product item are obtained. Obtained from the database 6, and in step S315, the second list price information and the change tag ID are written and the discount print information is printed.

  In the above, step S139A in the flow of FIG. 17 corresponds to the collating means.

  In the present variation configured as described above, in the register 3, step S110 in the flow of FIG. 17 obtains the article tag ID stored and held in the IC circuit unit 150 of the discount tag label Th, and step S140 receives the value. Based on the second item tag ID related to the discount tag label Th, the first list price information (or the second list price information) acquired based on the item tag ID of the list price tag label Tb is changed using the discount amount information. .

  At this time, in particular, in step S139A, the matching between the first list price information acquired based on the list price tag Tb and the second list price information acquired based on the discount tag label Th is collated, and it is determined that the match is recognized. Only when it is done, the first fixed price information acquired based on the article tag ID of the fixed price tag label Tb is changed. As a result, even if the user mistakenly acquires the list price information of the product 2 that is not assumed to be the target of changing the discount tag label Th and tries to change it using the discount price information related to the discount tag label Th, If it is inappropriate, it can be changed.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The present embodiment is an embodiment in the case where the present invention is applied to a monitoring system that monitors and monitors the entry or exit of articles or persons in a building such as a building.

  FIG. 18 is a diagram schematically showing the overall configuration of the monitoring system of the present embodiment. This example shows a case where the monitoring system 101 of the present embodiment is applied to an entire office building (building; hereinafter simply referred to as “building”) 102 having a plurality of floors, of which a predetermined number on each floor is shown. A plurality of rooms (for example, an office room, a hot water room, a break room, etc.) and a corridor on each floor are set as independent management target areas, and the management target areas 103 (in the figure) Through the dotted line). A management gate 103 is also provided in the middle of the stairway connecting the corridors of each floor to partition the floors of each floor, and an entrance door 104 which is an entrance passage to the outside of the building 102 is also included in the management gate 103. As one, the outside and the inside of the building 102 are separated.

  As described above, in the example of the building 102 shown in FIG. 18, the first floor corridor, the second floor corridor, the second floor A room, the second floor B room, the third floor hallway, the third floor A room, and the third floor B room are managed areas. The management gates 103 are provided at seven locations located at the boundaries of each management target area. In addition to these management target areas, a monitoring room 105 where an operator in charge of management (not shown, hereinafter referred to as “manager”) waits is provided in the first floor of the building 102.

  The monitoring system 101 is also connected to each reader 107 (radio tag information reading device) 107 installed in each management gate 103 in the building 102 and each reader 107 installed in the monitoring room 105 via the communication network NW. Terminal 108, management server 109, and tag label producing apparatus 110.

  One reader 107 is installed at each of the seven management gates 103. Each reader 107 has the same configuration, and when passing through each management gate 103, each tag Gj, Gkj is searched to detect each tag ID and the like (details will be described later). Although not specifically illustrated, each management gate 103 allows only one person 106 to pass through at the same time, and each unit passage operation is grouped by one pass by the one person 106 as a unit. Wireless tags Gj and Gkj are detected.

  The management server 109 includes passability information (movement restriction information, object information) indicating which management gate 103 is allowed to pass corresponding to the person tag ID stored in each person tag Gj, and each person. Passing permission information (changed information, movement restriction release information) indicating which management gate 103 specifically allows passage is stored corresponding to the person permission tag ID stored in the permission tag Gkj. Furthermore, when each tag Gj, Gkj is detected by each reader 107, the management server 109 determines whether or not the passage operation at the corresponding management gate 103 can be permitted based on the passage permission information and the passage permission information. When it is determined that the passing operation cannot be permitted, a notification process is performed for the administrator (details will be described later).

  In this example, all persons (objects) 106 that enter the building 102 such as employees and visitors of the company where the building 102 is located are set as monitoring targets and are set as monitoring targets. All persons 106 have a person tag Gj. Further, the restriction on the passage of the predetermined management gate 103 is changed for the predetermined person 106 among the persons 106 (in this example, the restriction is relaxed such that the passage is additionally permitted. A person permission tag (abbreviated as a permission tag in the figure) Gkj for possessing a strict restriction may be possessed. The person permission tag Gkj is held for a limited period (or only temporarily) when a predetermined condition is satisfied.

  The person tag Gj is affixed with a person tag label Tj (a wireless tag including a first wireless tag circuit element; details will be described later) having the same configuration as the fixed price tag label Tb used in the first embodiment. The IC circuit unit 150 of the RFID circuit element To included in the tag label Tj stores a person tag ID, which is identification information corresponding to the person 106 possessing the person tag Gj. In addition, the person permission tag Gkj possessed by the predetermined person 106 among the persons 106 also has a person permission tag label Tkj (a wireless tag including a second wireless tag circuit element having the same configuration as the regular price tag label Tb; details will be described later) The IC circuit unit 150 of the RFID tag circuit element To of the person permission tag label Tkj has a predetermined permission to allow the person 106 to pass only during the possession of the person permission tag Gkj. The person permission tag ID corresponding to the passage permission information describing the management gate 103 is stored.

  At this time, in the monitoring system 101, a suspicious person who does not have the person tag Gj enters each management target area, and even the person 106 who has the person tag Gj can pass information (a movement restriction mode of the person 106 in advance). ), Each management gate 103 detects an erroneous entry to the management target area where movement is restricted, and such an inappropriate passing operation of the management gate 103 is notified to the administrator as an entrance management abnormality. The And only when the person 106 who owns the person tag Gj further possesses the person permission tag Gkj, the restriction of movement based on the passage permission information is passed permission information (movement restriction release information of the person 106). Is partially or entirely released based on the above, and the passage through the corresponding management gate 103 is permitted (or the restriction may be strengthened and the passage may be prohibited as described above).

  FIG. 19 is a system configuration diagram illustrating an overview of the monitoring system 101 according to the present embodiment. In addition, the same code | symbol is attached | subjected about the part equivalent to the structure (refer FIG. 2) of the register | resistor 3 in the said 1st Embodiment, and description is abbreviate | omitted suitably. The tag label producing device 110 has the same configuration (see FIG. 4) as the tag label producing unit 11 provided in the register 3 of the first embodiment. explain.

  In FIG. 19, the monitoring system 101 is connected to the reader 107 for detecting the tag ID by wireless communication with the tags Gj and Gkj as described above, and to each reader 107 via an appropriate communication network NW. The terminal 108, the management server 109, and the tag label producing device 110 are configured. When an administrator (operator) resident in the monitoring room 105 operates the terminal 108, the terminal 108 transmits / receives an instruction signal and management information to / from the management server 109 via the communication network NW and is input. In response to the received instruction signal, a control signal is output from the management server 109 to each reader 107 via the communication network NW, and a detection result signal from the reader 107 is output to the management server 109.

  In addition, when a command signal is input from the terminal 108, a control signal is output from the management server 109 to the tag label producing device 110 via the communication network NW, and the tag label producing device 110 receives the person tag Gj or person as the RFID label. A permission tag Gkj is created.

  The reader 107 includes a control unit 111 and a reader antenna (reading side antenna) 113. If necessary, a sensor (for example, an infrared sensor) 112 that detects some passing operation in the management gate 103 and a sensor control unit 117 that controls the infrared sensor 112 are provided. Information transmission / reception to / from the RFID circuit element To may be performed.

  The control unit 111 includes a CPU (central processing unit) 114, a network communication control unit 115 that controls transmission and reception of control signals and information signals with the management server 109 via the communication network NW, and a RAM, a ROM, and the like, for example. And an RF communication control unit 118 that controls wireless communication with the tags Gj and Gkj via the reader antenna 113.

  The CPU 114 performs signal processing according to a program stored in advance in the ROM using the temporary storage function of the RAM, thereby accepting an input of a detection processing execution command from the management server 109, and wireless communication via the reader antenna 113. Thus, the tag Gj, Gkj is detected, and the detection result is output to the management server 109 via the communication network NW.

  The reader antenna 113 is an antenna whose communication distance is set longer than the planar antenna 4 of the register 3 in the first embodiment, and can detect the tags Gj and Gkj passing through the entire management gate 103.

  The management server 109 includes a CPU (Central Processing Unit) 121, a memory 122 similar to the above, and a large-capacity storage device such as a hard disk device, and a database 123 that stores various information relating to the tags Gj, Gkj, the readers 107, and the like. And a network communication control unit 124 that controls transmission / reception of control signals and information signals to / from the reader 107 via the communication network NW. Note that the database 123 is not limited to being provided in the management server 109, and an external database connected to be able to send and receive information via some kind of communication line may be used as in the first embodiment. Although not particularly illustrated, each reader 107 is preset with an identification number for individually identifying, and the management server 109 identifies one reader 107 using the identification number of the reader 107, Control signals and information signals are exchanged.

  The terminal 108 displays a CPU (Central Processing Unit) 131, a memory 132 similar to the above, an operation unit (setting signal input means) 133 for inputting instructions and information from the administrator, and various information and messages. Display unit (display signal output means) 134, network communication control unit 135 that controls transmission / reception of control signals and information signals to / from management server 109 via communication network NW, and passing operation that is not permitted in each management gate 103 And a buzzer 136 for notifying the administrator of the sound when the error is detected. This terminal 108 functions as a common operation terminal / display terminal for both the management server 109 and the tag label producing apparatus 110.

  The tag label producing device 110 has the same configuration as the tag label producing unit 11 provided in the register 3 in the first embodiment, and the network communication control unit 124 replaces the input / output I / F shown in FIG. Provided, and controls the exchange of control signals and information signals with the management server 109 via the communication network NW.

  FIG. 20 is a diagram illustrating an example of the overall schematic structure of the tags Gj and Gkj. FIG. 20A is a top view of the person tag Gj, and FIG. 20B is a top view of the person permission tag Gkj. 20 (a) and 20 (b), in this example, the tags Gj and Gkj each have a main body plate 148, and the surface of each main body plate 148 has the first embodiment as described above. The person tag label Tj or the person permission tag label Tkj having the same configuration as that of the tag labels Tb and Th of the form is affixed. In addition, it is good also as a card-type radio | wireless tag (it has a function equivalent to person tag label Tj or person permission tag label Tkj) instead of the label attachment system to such a main body plate 148.

  As shown in FIG. 20 (a), on the front side (upper surface) of the label main body 149 of the person tag label Tj, person print information (in this example, “Technology Department: Jiro Yamada” representing the affiliation and name of the person 106 possessing the person is provided. ") A person print area Aj on which Rj is printed is provided, and passability print information (in this example," only the first and second floors ") Rt is printed corresponding to the person 106 possessed. A region At is provided. Also, as shown in FIG. 20B, corresponding pass permission print information (in this example, “permit except for the third floor B room”) Rkj is printed on the front side (upper surface) of the label main body 149 of the person permission tag label Tkj. The passage permission print area (print area) Akj is provided. It should be noted that printing of the pass / fail print information Rt and the pass permission print information Rkj is not essential, and may be a figure, a code, or a simple color coating (can be colorless) or a pattern.

  As described above, the most significant feature of the present embodiment is that information is acquired by the reader 7 from the person permission tag Gkj that permits passage of other management gates 103 other than the management gate 103 that is set to pass through in advance. The processing corresponding to this is performed. Hereinafter, the details will be described in order.

  FIG. 21 is a flowchart illustrating a control procedure executed by the CPU 121 of the management server 109. In FIG. 21, for example, when a monitoring start instruction is input (for example, key operation) in the operation unit 133 of the terminal 108, this flow is started.

  First, in step S405, a variable M for specifying the management gate 103 to be monitored and the reader 107 corresponding thereto is initialized to 1.

  In step S410, the reader 107 (hereinafter referred to as the Mth reader 107) provided in the management gate 103 (hereinafter referred to as the Mth management gate 103) corresponding to the specific variable M via the communication network NW. A control signal is output to the control unit 111, and a question signal for requesting a response to all the tags Gj, Gkj such as a “Scroll All ID” signal is transmitted from the reader antenna 113, and the tags Gj, All response signals transmitted by Gkj are received by the same reader antenna 113, and it is determined whether any response signal has been received (whether passage operation has been detected). If any passing operation is detected, the determination is satisfied, and the routine goes to the next Step S420.

  In step S420, it is determined whether or not the person tag Gj has been read in step S410, that is, whether or not a person tag ID has been detected in the Mth management gate 103 in which the passage operation has been detected. If the person tag ID is not detected, the determination is not satisfied, that is, a suspicious person who does not have the person tag Gj is regarded as passing through the Mth management gate 103, and the communication network NW is set in step S425. The control signal is output to the terminal 108 and a notification process such as displaying a warning on the display unit 134 is performed (details will be described later), and this flow ends. On the other hand, if the person tag ID is detected, the determination is satisfied, and the routine goes to the next Step S430.

  In step S430, the database 123 is accessed and searched based on the person tag ID detected in step S410, the corresponding passability information is acquired from the database 123, and the process proceeds to the next step S435.

  In step S435, whether or not the person 106 possessing the person tag Gj storing the person tag ID detected in step S410 based on the passage permission information acquired in step S430 can pass through the Mth management gate 103. Determine whether. If it is set that the person 106 cannot pass through the Mth management gate 103 based on the passability information, the determination is not satisfied, that is, the person 106 who has the person tag Gj but cannot enter. It is considered that the vehicle is about to enter the target area, and the passage permission is further confirmed in steps S440 to S450.

  In the next step S440, it is determined whether or not the person permission tag Gkj is read in step S410, that is, whether or not the person permission tag ID is detected in the Mth management gate 103 in which the passage operation is detected. When the person permission tag ID is not detected, the determination is not satisfied, that is, the person 106 who is going to enter the management target area that cannot originally enter does not have the person permission tag Gkj and is about to enter unjustly. Therefore, the notification process is performed in step S425, and this flow ends. On the other hand, if the person permission tag ID is detected, the determination is satisfied, and the routine goes to the next Step S445.

  In step S445, the database 123 is accessed and searched based on the person permission tag ID detected in step S410, the corresponding passage permission information is acquired from the database 123, and the process proceeds to the next step S450.

  In step S450, whether or not the person permission tag Gkj that stores the person permission tag ID detected in step S410 based on the passage permission information acquired in step S445 permits passage through the Mth management gate 103 is determined. judge. If the person permission tag Gkj does not permit passage of the Mth management gate 103 based on the passage permission information, the determination is not satisfied, that is, the person 106 trying to pass through the Mth management gate 103 cannot enter. It is considered that the area to be managed is entered and is not specifically permitted, and a notification process is performed in step S425, and this flow is terminated. On the other hand, if the person permission tag Gkj permits the passage of the Mth management gate 103, the determination is satisfied, that is, the Mth management gate 103 is appropriately passed by the monitoring of the Mth reader 107. The operation is considered to be performed, and the process proceeds to the next step S455.

  On the other hand, if any response signal is not received in the determination in step S410 (passing motion is not detected) or the determination is not satisfied, or the person 106 is M based on the passability information in the determination in step S435. If it is set to pass through the th management gate 103 and the determination is satisfied, the process proceeds to step S455 without performing the notification process.

  In step S455, it is determined whether or not the above-described monitoring processing has been performed by all readers 107, that is, whether or not the specific variable M is the maximum value (7 in this example). If the monitoring processing has not been performed by all the readers 107 (the specific variable M is not the maximum value = 7), the determination is not satisfied, and 1 is added to the specific variable M in step S460, and the process returns to step S410. Repeat the same search loop procedure. On the other hand, if the monitoring process by all the readers 107 is performed in a single line, the determination is satisfied, and the routine goes to the next Step S465.

  In step S465, it is determined whether or not an operation for ending this flow has been performed on the operation unit 133 of the terminal 108. If the end operation has not been performed, the determination is not satisfied, and the flow returns to step S405 to repeat this flow from the beginning. On the other hand, if the end operation has been performed, the determination is satisfied, and this flow is ended.

  In addition, regarding the notification process in step S425, specifically, for example, a control signal is output to the terminal 108 and the buzzer 136 is sounded and an appropriate notification display is performed on the display unit 134. Announces abnormalities in passing operation. At this time, if each tag ID is detected, the name of the person 106 corresponding to the tag ID is searched from the database 123, and the management gate 103 (M-th management gate 103) entering is searched. At the same time, it may be displayed on the display unit 134 of the terminal 108.

  Although not specifically described in detail, the tag label creating apparatus 110 in the present embodiment also creates the person tag label Tj and the person permission tag label Tkj by the same control as the tag label creating unit 11 in the first embodiment. That is, the CPU 121 included in the management server 109 of the present embodiment creates the person tag label Tj and the person permission tag label Tkj by performing a control procedure equivalent to the flow described in FIG. 11 and FIG. In this case, the name of the person 106 is used in place of the product item, the person tag ID is used in place of the article tag ID, the person permission tag ID is used in place of the change tag ID, and instead of the fixed price printing information. The person print information and the pass / fail print information are used, and the pass permission print information is used instead of the discount print information. Further, in step S205 of FIG. 11 and step S305 of FIG. 12, the name (and affiliation) of the person 106 is input from the operation unit 133 of the terminal 108, respectively.

  In the above, step S410, step S430, and step S445 in the flow of FIG. 21 correspond to the information acquisition means described in each claim, and step S450 in the flow of FIG. 21 corresponds to the change processing means.

  As described above, in the present embodiment, the passage permission / prohibition information regarding the person 106 possessing the person permission tag label Tkj is managed in the IC circuit unit 150 of the RFID circuit element To provided in the person permission tag label Tkj. The person permission tag ID corresponding to the passage permission information for the change processing only in the server 109 is stored and held (the passage permission information itself may be written in the IC circuit unit 150 and stored). .

  Then, the management server 109 and each reader 107 communicate with the person 106 possessing the person tag label Tj based on the person tag ID stored and held in the IC circuit unit 150 of the RFID circuit element To provided in the person tag label Tj. A control procedure for acquiring the passage permission information based on the person permission tag ID stored and held in the IC circuit unit 150 of the RFID circuit element To of the person permission tag label Tkj. Steps S410, S430, and S445 in the flow are performed, and a control procedure (step S450 in the flow of FIG. 21) for changing the passage permission information using the acquired passage permission information is performed.

  As a result, there is no need to modify the passability information stored in the database 123 corresponding to the original person tag ID, so that the passability information in the database 123 is corrected and then restored again. Therefore, the general user can change the pass / fail information substantially in an easy and simple manner, without the need for bothersomeness and advanced knowledge for operating the database 123.

  In the present embodiment, the movement restriction of the person 106 is partially canceled such as allowing permission to enter other than the third floor B room as the passage permission information. However, the present invention is not limited thereto, All of the movement restrictions may be released by permitting the passage through the management gate 103. Further, the passage permission information itself may be stored in the person permission tag label Tkj.

  Also in the present embodiment, modifications similar to the two modifications of the first embodiment are possible. That is, according to the modified example (1-1) of the first embodiment, a person tag ID as identification information of the person 106 may be stored in the person permission tag label Tkj together with the person permission tag ID. The reader 107 detects the first person tag ID from the person tag label Tj, and detects the second person tag ID and the person permission tag ID from the person permission tag label Tkj. Then, although not particularly illustrated, after step S445 in the flow of FIG. 21, a collation determination is performed as to whether or not the first person tag ID and the second person tag ID match. If they match, the process proceeds to the next step S450. If not, the notification process is performed.

  As a result, when the user erroneously acquires the pass permission information of the person 106 who is not supposed to be changed as the person permission tag label Tkj and tries to change it using the pass permission information of the person permission tag label Tkj, the first person tag It is possible to take various measures such as checking the ID and the second person tag ID to confirm that they are not originally changed in some form or making the change impossible if the check is inappropriate.

  Further, according to the modified example (1-2) of the first embodiment, the person permission tag label Tkj may store passage permission information together with the person permission tag ID. In this case, the reader 107 may use the person tag label. The person tag ID is detected from Tj, and the second passage permission information and the person permission tag ID are detected from the person permission tag label Tkj. Although not particularly illustrated, the first passage permission information acquired corresponding to the person tag ID after step S445 in the flow of FIG. 21 matches the second passage permission information directly detected from the person permission tag label Tkj. Whether or not they match is determined. If they match, the process proceeds to the next step S450, and if they do not match, a notification process is performed. In this case, the same effect as described above can be obtained.

  In the second embodiment, various modifications can be made without departing from the spirit and technical idea of the second embodiment. Hereinafter, such modifications will be described in order.

(2-1) When an article is a monitoring target In the second embodiment, the person 106 to be managed is set as the monitoring target. However, the present invention is not limited to this, and the article to be managed is the monitoring target. It may be set.

  FIG. 22 is a diagram schematically showing the overall configuration of the monitoring system 101 of this modification. In this example, normally, articles (objects) to be managed 141 such as documents, fixtures, project files and the like to be stored in any of the predetermined rooms in the building 102 are set as monitoring targets. An article tag Gb is attached to all the articles 141 to be managed (or may be associated in some form such as bundling). Further, among the above-described articles 141, a predetermined article 141 is attached with an article permission tag Gkb (abbreviated as a permission tag in the drawing) that additionally permits passage of the predetermined management gate 103. This article permission tag Gkb is attached for a limited period (or temporarily) when a predetermined condition is satisfied.

  The product tag label Tb having the same configuration as the person tag label Tj used in the second embodiment is affixed to the product tag Gb, and the IC circuit unit 150 of the RFID circuit element To included in the product tag label Tb includes An article tag ID that is identification information corresponding to the article 141 to which the article tag Gb is attached is stored. Moreover, the article permission tag label Tkb having the same configuration as the article tag label Tb is also attached to the article permission tag Gkb attached to the predetermined article 141 among the articles 141. In the IC circuit section 150 of the RFID circuit element To of the article permission tag label Tkb, the restriction on the passage of the article 141 is changed only while the article permission tag Gkb is attached (in this example, the passage is additionally added). The article permission tag ID corresponding to the passage permission information describing the predetermined management gate 103 is stored.

  The monitoring system 101 of the present modification monitors only the management target item 141 to which the item tag Gb is attached, and the movement is limited based on the passability information (movement limit mode of the item 141) in advance. Each management gate 103 detects an erroneous entry to the management target area, and notifies the manager of such an inappropriate passing operation of the management gate 103 as an entrance management abnormality. And only when the article permission tag Gkb is further attached to the article 141 to which the article tag Gb is attached, the movement restriction based on the passage permission information is permitted as the passage permission information (movement restriction release information of the article 141). Is partially or entirely released based on the above, and the passage through the corresponding management gate 103 is permitted (or the restriction may be strengthened and the passage may be prohibited as described above).

  Other hardware configurations (reader 107, management server 109, terminal 108, tag label creating apparatus 110) in this modification are exactly the same as those of the second embodiment shown in FIG. The control procedure performed by the CPU 121 is only slightly different. Hereinafter, the control procedure will be described.

  FIG. 23 is a flowchart showing a control procedure executed by the CPU 121 of the management server 109 in this variation, and corresponds to FIG. 21 in the second embodiment. The flow in FIG. 23 is roughly the same as the flow in FIG. 21 except that the procedure of step S420A is basically performed instead of step S420 in the flow of FIG. In step S430, passability information corresponding to the article tag ID is acquired from the database 123. In step S435, it is determined whether or not the article tag ID can be passed. In step S440, the article permission tag ID is detected. In step S445, passage permission information corresponding to the article permission tag ID is acquired from the database 123. In step S450, it is determined whether passage of the article permission tag ID is permitted. Only the above-described different procedures will be described below.

In FIG. 23, in step S410, “Scroll All
In response to the “ID” signal, all the response signals transmitted by the tags Gb and Gkb are received by the reader antenna 113 and passed, and then the process proceeds to step S420A, and the response signals from the tags Gb and Gkb detected in step S410 are displayed. It is determined whether or not an article tag ID is included.

  In this example, the article tag Gb is attached only to the managed article 141 for which movement restrictions are set for security management among many articles 141 stored in each managed area in the building 102. Therefore, it is not necessary to monitor the unmanaged item 141 to which the item tag Gb is not attached. Therefore, if the article tag ID is not detected, the determination is not satisfied, that is, the article 141 (or the person 106) passing through the Mth management gate 103 is considered not to be monitored, and step S455 is performed. Move on. On the other hand, if the article tag ID is detected, the determination is satisfied, that is, it is assumed that the article 141 to be managed has passed through the Mth management gate 103, and the process proceeds to the next step S430. Other procedures are the same as those in FIG. 21, and a description thereof will be omitted.

  Although not specifically described in detail, the tag label producing apparatus 110 in the present modification also produces the article tag label Tb and the article permission tag label Tkb by the same control as the tag label producing unit 11 in the first embodiment. That is, the CPU 121 included in the management server 109 of the present modification creates the article tag label Tb and the article permission tag label Tkb by performing a control procedure equivalent to the flow described in FIG. 11 and FIG. In this case, the name of the article 141 is used instead of the commodity item, the article permission tag ID is used instead of the change tag ID, and the article printing information (for example, the name of the article 141) is substituted for the regular price printing information Rb. And pass / fail print information is used, and pass permission print information is used instead of the discount print information Rh.

  Further, in step S205 of FIG. 11 and step S305 of FIG. 12, the name of the article 141 is input from the operation unit 133 of the terminal 108, respectively. Further, the appearances of the article tag label Tb and the article permission tag label Tkb to be created are not particularly shown, but the person tag label Tj shown in FIGS. 20A and 20B created in the second embodiment is used. It differs in that it is printed with the same appearance as the person permission tag label Tkj, and an article printing area for printing article printing information is provided instead of the person printing area Aj in the person tag label Tj of FIG.

  In this modification configured as described above, the reader 107 and the management server 109 read the article tag ID of the RFID circuit element To of the article tag label Tb related to the article 141 that is assumed in advance as a change target of the article permission tag label Tkb. The management server 109 obtains the passage permission information corresponding to the article tag ID from the database 123, while reading the article permission tag ID for the article permission tag label Tkb and based on this, the passage permission information is obtained from the database 123. Thus, the acquired passability information can be changed by the pass permission information only in the management server 109.

  Therefore, since it is not necessary to modify the passability information stored in the database 123 corresponding to the original article tag ID, the passability information in the database 123 is corrected and then restored again. Thus, the general user can substantially change the pass / fail information by an easy and simple method without the need for such annoyance or advanced knowledge for operating the database 123.

  Note that this modification can be modified in the same manner as the two modifications of the first embodiment.

(2-2) When a person and an article are set as monitoring targets Furthermore, the management target person 106 and the management target article 141 may be combined and set as a monitoring target.

  This modified example is a modified example of monitoring the taking-out / taking-in of the article 141 by the person 106 by combining the second embodiment and the modified example (2-1). The person tag Gj, the person permission tag Gkj, the article The hardware configuration including the tag Gb and the article permission tag Gkb is exactly the same as that of the second embodiment shown in FIG. 19 and the modified example shown in FIG. The control procedure performed by is slightly different. Hereinafter, the control procedure will be described.

  FIG. 24 is a flowchart illustrating a control procedure executed by the CPU 121 of the management server 109 in this modification. The flow of FIG. 24 is roughly the same as the flow of FIG. 21, and basically a person monitoring process (step S600 in the figure) including the steps S420 and S430 to S450 in the flow of FIG. The point that the article monitoring process of step S700 is performed together is omitted. Other procedures are the same as those in FIG. 21, and a description thereof will be omitted.

  FIG. 25 is a flowchart showing a detailed procedure of the person monitoring process executed by CPU 121 of management server 109 in step S600 in FIG. The flow of FIG. 25 is the same as the procedure of step S420 and step S430 to step S450 in the flow of FIG. 21, and the determination is not satisfied in step S620, the determination is not satisfied in step S640, and the determination is made in step S650. If not satisfied, the process proceeds to the notification process in step S525 in FIG. If the determination is satisfied in step S635, the process proceeds to the article monitoring process in step S700 in FIG.

  FIG. 26 is a flowchart showing the detailed procedure of the article monitoring process executed by CPU 121 of management server 109 in step S700 in FIG. The flow in FIG. 26 is the same as the procedure in steps S420A and S430 to S450 in the flow in FIG. 21. In step S720, it is determined that the item tag ID is detected, and in step S730, the flow corresponds to the item tag ID. Passability information is acquired from the database 123. In step S735, it is determined whether or not the article tag ID can be passed. In step S740, the detection of the article permission tag ID is determined. In step S745, the article permission is determined. The passage permission information corresponding to the tag ID is acquired from the database 123, and it is determined in step S750 whether or not the passage of the article permission tag ID is permitted.

  If the determination is not satisfied in step S740 and if the determination is not satisfied in step S750, the process proceeds to the notification process in step S525 in FIG. If the determination is not satisfied in step S720 and if the determination is satisfied in step S735, the process proceeds to step S555 in FIG.

  Although not specifically described in detail, the tag label producing apparatus 110 in the present modification is also controlled by the same control as the tag label producing unit 11 in the first embodiment. Create

  In the above description, the pass / fail information corresponding to the person tag ID and the article tag ID corresponds to a mode of restricting the take-out / taking-in of the article 141 by the person 106. Further, the passage permission information corresponding to the person permission tag ID and the article permission tag ID corresponds to release information on the restriction of taking out / taking in the article 141 by the person 106.

  In the present modification configured as described above, the effects of the second embodiment and the modification of (2-1) can be obtained together. That is, since it is not necessary to correct the passability information stored in the database 123 corresponding to the original person tag ID and the article tag ID, the passability information in the database 123 is corrected. A general user can substantially change the passability information by an easy and simple method without requiring bothersomeness as in the case of returning to the original state again and advanced knowledge for operating the database 123.

  Note that this modification can be modified in the same manner as the two modifications of the first embodiment.

  Further, in the tag label producing unit 11 and the tag label producing device 110 described above, information is written to the IC circuit unit 155 of the RFID circuit element To and printing for identifying the RFID circuit element To is performed by the print head 10. It is not limited to things. This printing is not necessarily performed.

  Note that the “Scroll All ID” signal and the like used above are compliant with the specifications established by EPC global, but signals that comply with other standards may be used as long as they perform the same function. .

  In the above description, the tag identification information of the RFID tag circuit element To (target RFID circuit element) of the tag label Tb (target RFID tag) related to the product 2 preliminarily assumed to be changed is used as the RFID tag information of the register 3. While reading with the function as a reading device and acquiring corresponding object information from the database 6 based on the link, the RFID tag circuit element To (change RFID tag circuit element) of the tag label Th (change RFID tag) Is also read and the change information is acquired based on this, so that all or a part of the acquired object information is changed (changed / corrected after being read and recognized) However, it is not limited to this. That is, the object information may be stored as other storage media that can be read by wireless communication other than the wireless tag or information of other aspects, for example, barcode information, and may be changed.

  In this case, information such as barcode information relating to an object assumed in advance as a change target may be stored in a barcode scanner or the like (which may be provided in the register 3 or connected to the register 3 via the network NW). And the corresponding object information is acquired from the database 6 based on the preset link, while the RFID tag circuit element To (change RFID tag circuit element) of the tag label Th (change RFID tag) ), And the change information is acquired based on the read information to change all or a part of the acquired object information (recognized by changing / correcting after reading). What should I do? In this case as well, the object information in the database 6 linked to the original barcode information or the like does not need to be corrected while maintaining the object information in the same manner as described above. The general user can substantially change the contents of the object information by an easy and simple method without requiring bothersomeness and high-level knowledge as in the case of returning to the original state after correction.

  Furthermore, in addition to those already described above, the methods according to the above embodiments and modifications may be used in appropriate combination.
