  As shown in the figure, the information display system SY includes a serving tray 1 on which dishes 6, 7, and 8 (containers) loaded with ingredients (cooking, food, etc.) are placed, and the back surfaces of the dishes 6, 7, and 8. And a wireless tag 20 (see FIG. 4) attached to the device. Note that RFID (Radio Frequency Identification) is used as the wireless tag 20. The RFID may be an active type with a built-in battery, but in the present embodiment, it is preferable to use a passive type in order to reduce the cost. Further, although not shown in particular, foodstuffs put in a bag, such as bread and rice balls, do not require tableware, so the wireless tag 20 is attached to the package. As a general RFID structure, a unique code recorded in a ROM (hereinafter referred to as type 1) at the time of shipment from a manufacturer (hereinafter referred to as type 1) and a unique code + rewritable memory area (hereinafter referred to as type) 2) and all types of rewritable memory areas (hereinafter referred to as type 3). In the first embodiment, an RFID including the rewritable memory areas of type 2 and type 3 is used in the first embodiment. Used.

  A wireless tag reader 10 is detachably attached to the tray 1 for each tray. The wireless tag reader 10 is attached to the right front side of the flat portion 4 on which the tableware 6, 7, 8 is placed so as not to disturb the arrangement of the tableware 6, 7, 8. In addition, the wireless tag reader 10 reads the wireless tags 20 attached to the dishes 6, 7, and 8 and displays various information recorded in the wireless tags 20 on the display 11 (display unit). The information recorded in the wireless tag 20 includes a code (tag ID) for identifying the wireless tag 20 or a unique code for each tableware or package, and a code (numerical value, symbol, character) indicating part or all of the food information. Column). In the following description, it is assumed that a tag ID and a food code are stored in the wireless tag 20.

  The customer holds the tray 1 with the RFID tag reader 10 in his / her hand, goes around the store, selects the dishes 6, 7, and 8 with the favorite ingredients from the display shelf 31, and selects the tray 1 for the tray. put on top. Ingredients include ingredients that are sold by weight and ingredients that have a uniform weight per tableware. For ingredients that are sold by weight, customers put their favorite amount on the tableware (tableware 6 in Figure 1). The weight is measured with the weight measuring device 32. The weight measuring device 32 is equipped with a writer function for writing a measurement value to the wireless tag 20, and the measurement value (weight) can be written while the tableware 6 is placed on the placement unit 32 a. .

  On the other hand, the wireless tag reader 10 reads the wireless tags 20 of the dishes 6, 7, and 8 placed on the tray 1 for serving, and arranges various information held in the wireless tags 20 (displayed on the dishes 6, 7, and 8). The name of the selected food, the allergen contained in the food (food information), the fee and the weight, etc.) are displayed on the display 11. The customer selects food ingredients while confirming the information on the display 11 and goes to the checkout office when the selection is completed.

  A POS terminal (cash register terminal) 40 equipped with a code reader 41 is installed at the checkout office. The cashier person operates the wireless tag reader 10 to display the settlement information 60 on the display 11 (see FIG. 11), and the code reader 41 reads the two-dimensional code 63 displayed as a part of the settlement information 60. The cashier person performs a settlement process based on the reading result, and finally removes the wireless tag reader 10 from the tray 1 for serving. When the customer finishes the meal at the predetermined place, the customer returns the serving tray 1 and the dishes 6, 7, and 8 to the predetermined return place in the same manner as a return method in a general self-service restaurant.

  Note that the RFID tag reader 10 may be returned without being collected by the cashier in charge while being attached to the layout tray 1. Further, instead of mounting one by one on the distribution tray 1, each customer may carry it by himself and install it on the distribution tray 1 when he / she enters the store. In this case, by installing the function of the wireless tag reader 10 in a mobile phone or the like that is widely used, the customer can easily receive the service provided by the information display system SY. Moreover, the cost required for system construction can be reduced also for the store side.

  Next, with reference to FIG. 2, the appearance and configuration of the tray for layout 1 will be described. FIG. 2A is a schematic diagram showing the appearance of the serving tray 1 before the dishes 6, 7, and 8 are placed thereon. A conductor 19 serving as an antenna 9 is arranged in a coil shape on the tray edge 5 of the tray 1 (see FIG. 2B), but the surface is covered with paint or plastic mold. It has no structure. Reference numeral 2 denotes a connection terminal portion of the conductor 19. A wireless tag reader 10 that reads the wireless tag 20 is connected to the connection terminal portion 2, and the conductor 19 arranged in a coil shape functions as the antenna 9. Reference numeral 3 denotes a support portion for fixing the wireless tag reader 10, and is configured such that the wireless tag reader 10 can be held (positioned and set) by the tray edge portion 5 and the support portion 3. That is, the layout tray 1 includes the antenna 9 and the connection terminal portion 2 to which the wireless tag reader 10 is connected in the tray body including the flat portion 4 and the tray edge portion 5 that borders the four sides of the flat portion 4. It is configured.

  FIG. 2B is a schematic diagram showing a state where the surface of the tray 1 for painting is painted or the plastic mold is peeled off, and shows the conductor 19 of the antenna 9. The antenna 9 is arranged along the tray edge 5 of the tray 1 for serving so as to surround the dishes. In such a configuration, it is effective for a radio wave 20 having a low frequency, for example, about 130 KHz, and by placing the tray edge portion 5 of the tray for tray 1 along, the dishes 6, 7, 8 placed therein The wireless tag 20 can be read reliably.

  Next, the control configuration of the wireless tag reader 10 will be described with reference to FIG. The wireless tag reader 10 includes a connection terminal unit 2, an operation button 13, a power switch 14, a display 11, a CPU 15, a ROM 16, a RAM 17, and a power source 18.

  The connection terminal portion 2 is connected to the antenna 9 (conductor 19) and used to communicate with the wireless tag 20 attached to the dishes 6, 7, and 8. The operation button 13 is a so-called push button type switch, and is used by a customer or a cashier person for various operations. The wireless tag reader 10 of the present embodiment is assumed to have two operation buttons (A button 13a and B button 13b) (detailed functions will be described later). The power switch 14 is for performing ON / OFF operation of the power source 18, and is configured by a slide switch or the like. The display 11 is a liquid crystal display and displays various types of information including the reading result of the wireless tag 20.

  The CPU 15 is a central control device, and the ROM 16 stores various control programs and various control data for the CPU 15 to perform various arithmetic processes. Specifically, a calculation program for calculating the total price of food, an extraction program for extracting allergen substances contained in the food, a display control program for performing display control, and communication control with the wireless tag 20 are performed. For example, a message control database for displaying advice information 70 (see FIG. 11) to the customer. The RAM 17 is used as a work area for the CPU 15 to perform various arithmetic processes. In the following description, CPU 15, ROM 16 and RAM 17 are collectively referred to as “control system 80”.

  Next, with reference to FIG. 4, the functional configuration of the tray for layout 1 (mainly the wireless tag reader 10) will be described. The wireless tag reader 10 attached to the tray 1 has, as main functional components, a reading unit 110, an operation unit 120, a display control unit 130, an allergen extraction unit 140, a charge calculation unit 150, and a control unit that performs overall control of these units. 100.

  The reading unit 110 reads various information from the wireless tag 20 attached to the tableware 6, 7, 8 via the antenna 9 arranged on the tray edge 5 of the tray 1 for connection. The main part is constituted by. As various types of information, the tag ID of the wireless tag 20, identification information (food name) for identifying the food material, food material information regarding the content of the food material, fee information regarding the price of the food material, weight information regarding the weight of the food material, and the like are read.

  In the present embodiment, information (hereinafter referred to as “allergen information”) in which allergen substances are associated with contents (including ingredients and seasonings) are read as food information. Allergen substances are subject to mandatory allergen labeling (eg, eggs, milk, wheat, buckwheat, and peanuts). For example, when the food material is “shrimp pilaf”, the allergen substance (for example, “egg”) and the contents (materials) containing it are read as the food material information. Allergen substances include not only the mandatory items listed above, but also recommended items for allergen labeling (abalone, squid, how much, shrimp, orange, crab, kiwifruit, beef, walnut, salmon, mackerel, soy, chicken, pork , Matsutake, peach, yam, apple, gelatin, banana (20 items) are also preferred.

  On the other hand, as the fee information, either the first fee information indicating the fee per unit weight of the food or the second fee information indicating the fee per food item (single item fee) is read. In other words, depending on the ingredients (cooking), it can be assumed that the food is sold by weight and the weight per tableware is unified, but in the former case, the customer can use the tableware 6, 7, 8 as much as they like. Therefore, if the first fee information is recorded in the wireless tag 20, it is only necessary to measure the weight by the weight measuring device 32 and record the value, which is convenient.

  The operation unit 120 is used by a customer to perform various settings and operations, and the operation button 13 constitutes a main part. Although specifically described later, the operation button 13 can be used to set an allergen substance to be noted, a settlement instruction, an information reset, and the like. The allergen substance is set to display the allergen according to the customer. Further, the clearing instruction specifically instructs the calculation of the total charge of all the ingredients on the serving tray 1. When a settlement instruction is given by the operation unit 120, the reading unit 110 rereads all the wireless tags 20 on the layout tray 1.

  The display control unit 130 performs display control of the display 11, and a main part is configured by the control system 80. The display control unit 130 causes the display 11 to display the ingredient name, allergen information, single item price, and total price of the food every time the reading unit 110 reads.

  The allergen extraction unit 140 extracts allergen information when the allergen information read by the reading unit 110 includes an allergen substance set by the customer, and the control system 80 constitutes a main part. The For example, when the food is “shrimp pilaf”, the allergen information (egg / ingredient) is read, but only when the customer sets “egg” as the “allergen substance to be aware of” (egg egg). / Ingredient) is extracted. In other words, when the customer does not set “egg” as “a noteable allergen substance”, even if the allergen information is included in the information read from the wireless tag 20, it is not extracted. Depending on the food, there may be a case where a plurality of allergen information is included, but when there are a plurality of allergen information corresponding to the allergen substance set by the customer for one food, all of them are extracted (FIG. 10). Reference number 55, see “Allergen” column of food “Western food plate”). The extracted allergen information is displayed on the display 11 by the display control unit 130.

  The fee calculation unit 150 calculates the total fee by summing the single item charges of all ingredients on the tray 1 based on the fee information read by the reading unit 110. Is configured. As described above, as the fee information, either the first fee information indicating the fee per unit weight of the ingredients or the second fee information indicating the fee per ingredient is read, and the first fee information of the former is read. In such a case, the multiplication result of the charge per unit weight of the food and the weight of the food based on the weight information is calculated as a single food charge. Whether the read fee information is the first fee information or the second fee information may be determined by the presence or absence of weight information, or additional information added to each fee information or any fee information It may be determined by information.

  Next, the operation (display control method) of the wireless tag reader 10 will be described with reference to the flowcharts of FIGS. Here, it is assumed that the customer has already set “allergens to be aware of”. As shown in FIG. 5, when the wireless tag reader 10 detects the wireless tag 20 attached to the dishes 6, 7, 8 when the customer places the dishes 6, 7, 8 on the serving tray 1 ( (S01: Yes), various information recorded in the wireless tag 20 is acquired (S02). The acquired information is temporarily stored in a predetermined area of the RAM 17. Subsequently, it is determined whether or not the food placed on the serving tray 1 is one item (S03). Whether or not there is one item is determined by whether or not there is already stored information in a predetermined area of the RAM 17. Further, the reading of the same wireless tag 20 is ignored. Whether or not they are the same is determined by whether or not the tag IDs are the same.

  If it is determined in S03 that the item is one item (S03: Yes), the fee information (single item fee) read from the wireless tag 20 is set as the total fee (S04). If it is determined that the item is not one item (two items or more) (S03: No), the fee information (single item fee) read from the wireless tag 20 is added to the total fee so far to obtain the total fee. (S05).

  In addition, it is determined whether or not allergen information is included in the information read from the wireless tag 20 (S06), and if included (S06: Yes), the allergen information is set by the customer as “noticeable”. It is determined whether or not it corresponds to “allergen substance” (S07). Here, when there is allergen information corresponding to the “allergen substance to be noted” (S07: Yes), the ingredient name, allergen information, single item price, and total price are displayed on the display 11 (S08). On the other hand, when the allergen information is not included in the information read from the wireless tag 20 (S06: No), or even if the allergen information is included, the allergen information does not correspond to the “allergen substance to be noted” ( S07: No), the name of the ingredient, the single item fee, and the total fee are displayed on the display 11 (S09).

  Also, as shown in FIG. 6, when the depression of the settlement button (A button 13a, see FIG. 7) is detected (S10: Yes), the settlement information 60 and the advice information 70 are displayed (S11, see FIG. 11). . Further, when it is detected that the reset button (B button 13b, see FIG. 7) is pressed (S12: Yes), the read information stored in the predetermined area of the RAM 17 is erased and the display 11 is displayed in the initial state (power supply). The state immediately after the power ON operation by the switch 14 (see FIG. 7) is set (S13).

  Next, display contents displayed on the display 11 of the wireless tag reader 10 and an operation method of the wireless tag reader 10 will be described with reference to FIGS. FIG. 7 shows an example of an initial screen displayed immediately after the power-on operation. On the initial screen, a message 50 prompting the user to input “allergens to be noted” is displayed. Here, selection / non-selection is determined for five items which are the mandatory items for allergen display. The selection method is as shown in the message 51. The item is moved with the A button 13a, and the selection / non-selection is switched with the B button 13b. The illustrated example shows a case where the allergen substances “egg” and “wheat” are selected (a black circle indicates selection and a white circle indicates non-selection).

  When selection / non-selection of each allergen substance is determined on the initial screen shown in FIG. 7, the screen transitions to the screen shown in FIG. Here, a message 52 indicating that the wireless tag 20 is in a readable state (“Please place tableware on the tray”) 52 and a message 53 indicating the operation method are displayed. As shown in the message 53 indicating the operation method, when the A button 13a is pressed on a screen other than the initial screen, a transition is made to a screen (see FIG. 11) for displaying the settlement information 60 and the advice information 70 (however, FIG. When the A button 13a is pressed on the screen shown in FIG. 8, since no food is placed on the tray 1 for serving, the clearing information 60 and the advice information 70 are not displayed). Further, when the B button 13b is pressed, all read contents are reset.

  Here, when one item of food (tableware 6, 7, 8) is placed on the serving tray 1, the screen transitions to the screen shown in FIG. Here, a message 54 indicating the number of read ingredients, single item information 55 that is information only about the read ingredients, total information 56 that is information based on all the read ingredients, and a message 53 indicating the operation method described above , Is displayed. As the single item information 55, the read tag ID, food name (identification information), allergen substance, and single item price are displayed. As the allergen substance, the allergen substance contained in the food material (corresponding to “allergen substance to be noted” set in the initial screen (see FIG. 7)) is displayed. In addition, as a single item fee, if the shrimp pilaf with the tag ID “0123” is a food sold by weight, a value obtained by multiplying the fee per gram (first fee information) and the weight is displayed. . If the weight information is included in the information read from the wireless tag 20, the weight may be displayed as the single item information 55. Moreover, as the total information 56, the total number of the read foodstuffs, all allergen substances, and a total charge are displayed. Here, since there is one item, the total charge displays the same value as the single item charge.

  Here, when food is further placed on the tray 1 for serving, the screen changes to the screen shown in FIG. As the number of ingredients increases, the display of the message 54 is changed from “1 product” to “2 items”, and the newly read food information is additionally displayed as single product information 55 (see tag ID “1234”). . Further, as the total information 56, the total number of the two ingredients, all allergen substances, and the total fee are updated.

  FIG. 11 shows a screen displayed after the screen shown in FIG. 10 has been displayed and another food (see tag ID “2345”) is placed on the distribution tray 1 and the A button 13a is pressed. An example of the (clearing screen) is shown.

The two-dimensional code 63 is obtained by coding the settlement information 60 and is read by the code reader 41 (see FIG. 1) at the time of settlement. Accordingly, the cashier person can quickly perform the clearing process only by reading the two-dimensional code 63 without manually inputting the fee for each ingredient into the POS terminal 40. Further, since the wireless tag reader 10 rereads the wireless tag 20 and recalculates the total fee when the A button 13a is pressed, the cashier person finally presses the A button 13a, so The reading omission of the tag 20 can be prevented.

  When the A button 13 a is pressed, advice information 70 is displayed together with the settlement information 60. In the present embodiment, as the advice information 70, information on the contents including the quality of the menu balance of the selected food and the “allergens to be noted” is displayed. The quality of the menu balance is determined by referring to a table (not shown) that associates the menu with its ingredient attributes (classified according to the three major nutrients, the five major nutrients, etc.), and the distribution of the ingredient attributes is not biased It can be determined by various methods, such as determining that it is good. In addition, the information on the contents includes “food name”, “content” included in the allergen information, and “allergen substance” in a predetermined template “***”, “***” and “***”. Display the text data generated by inserting into "Used".

  As described above, according to the first embodiment, the allergen information (food material information) included in the contents of the food material is read from the wireless tag 20 attached to the tableware 6, 7, 8 and displayed. Allergen substances can be confirmed simply by placing the dishes 6, 7, 8 on the serving tray 1. Thereby, in a self-service restaurant, foodstuffs can be selected while confirming allergen substances, which is convenient for customers who need attention.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. In the first embodiment, the allergen information and the like are read from the wireless tag 20, but in this embodiment, the tag ID is read from the wireless tag 20, and the identification is performed by referring to the correspondence table T in the wireless tag reader 10. It differs in that it specifies information (food name), allergen information, single item price, etc. Therefore, in this embodiment, it is possible to use an RFID that does not have the above-described type 1 rewritable memory. Only differences from the first embodiment will be described below.

  As shown in FIG. 12, the wireless tag reader 10 of this embodiment has a configuration in which a storage unit 160 is added to the wireless tag reader 10 of the first embodiment shown in FIG. The storage unit 160 stores a correspondence table T in which the tag ID of the wireless tag 20 is associated with various pieces of information regarding each food material, and a main part is configured by the ROM 16 (see FIG. 3).

  As shown in FIG. 13, the correspondence table T associates tag IDs, identification information (food material names), allergen information, and charges. For example, when the reading unit 110 reads the tag ID “0123” from the wireless tag 20, the control unit 100 refers to the correspondence table T and determines that the identification information is “shrimp pilaf”. The allergen extraction unit 140 refers to the correspondence table T and extracts allergen information corresponding to “allergen substances to be noted”.

  In the second embodiment, in order to enable use of the wireless tag 20 having no rewritable memory, the price is determined in units of tableware instead of selling by weight (the price is described in the correspondence table T). . The control unit 100 causes the display control unit 130 to display the screen shown in FIG. 9 based on these determination / extraction results and calculation results. That is, only the tag ID is recorded in the wireless tag 20 (for example, the tag ID “1234” of the Western food plate, the tag ID “2345” of the oolong tea, etc.), and in this case, the charge described in the correspondence table T is used separately. It displays on the display 11 as a charge.

  As described above, according to the second embodiment, since the tag ID should be stored in the wireless tag 20 at a minimum, the storage capacity can be reduced. Further, even when there is a change in the ingredients to be placed / packaged on the tableware 6, 7, 8, it can be easily handled by rewriting the correspondence table T. In this case, as the ROM 16 for storing the correspondence table T, a rewritable flash ROM or the like is used.

  In order to quickly and reliably rewrite the correspondence table T, the store has an in-store server that performs overall control of the wireless tag reader 10, and distribution of table information (preferably wireless communication) from the in-store server allows the plurality of wireless tag readers 10 to be rewritten. It is preferable that the correspondence table T can be rewritten all at once. Further, the storage unit 160 of the wireless tag reader 10 may be configured with a removable storage medium.

  In the present embodiment, the tag ID is stored in the wireless tag 20, but the identification information (tableware / packaging code is used instead of the tag ID by using the above-described type 2 and type 3 RFIDs. + Foodstuff name) may be stored. In other words, any type of information can be used as long as the information can uniquely identify the container and the food. The reason why the containers are specified is that even when a plurality of the same foodstuffs are placed on the serving tray 1, the wireless tag reader 10 can identify each of them without reading failure.

  In the above two embodiments, the name of the food (dish) is exemplified as the identification information. However, the type of food (Japanese style, Chinese style, Western style, etc.), the appearance (color) of the dishes 6, 7, 8 (containers) Or the shape), the code affixed or printed on the tableware 6, 7, 8 and the like, any information that allows the user to identify the food (tableware 6, 7, 8) by looking at the identification information.

  In the above-described two embodiments, the case where allergen information is displayed as the food material information is exemplified. However, “information regarding food contraindications of religion” may be displayed. For example, in the case where the “information regarding the food contraindications of religion” is displayed in the second embodiment, the correspondence table T <b> 2 shown in FIG. 14 may be stored in the ROM 16 of the wireless tag reader 10. As shown in the figure, in the correspondence table T2, “information about religious contraindications” is recorded in association with tag IDs and identification information. “Religious Food Contraindication Information” is information that associates religion, contraindicated food, and contents (may be represented by food classification such as “hors d'oeuvre”, “dessert”, “condiment”). is there. In this case, the customer sets his / her religion on the initial screen (see FIG. 7). Thereby, when the content of the selected foodstuff contains a contraindicated food for one's own religion, the incompatible food can be displayed on the display 11.

  In addition, as shown in FIG. 15, “information regarding dietary restrictions” may be displayed. In this case, the correspondence table T3 in which the tag ID is associated with “meal restriction information” may be stored in the ROM 16 of the wireless tag reader 10. “Information on dietary restrictions” is information in which a disease name, food (component), and contents (classification) are associated with each other. In this case, the customer sets his / her disease name on the initial screen (see FIG. 7). Thereby, when the foodstuff (component) which becomes a problem by chronic disease is contained in the contents of the selected foodstuff, the foodstuff can be displayed on the display 11. When this correspondence table T3 is used, as the advice information 70, a symptom when the food (component) is ingested (for example, when the ventilated person selects “shrimp pilaf”, the food “ It is preferable to display information such as that the blood sugar level rises due to the intake of “squid”.

In the above-described two embodiments, the antenna 9 is arranged so as to surround the dishes along the tray edge portion 5 of the serving tray 1. However, the antenna 9 is provided in the wireless tag reader 10. May be. According to this configuration, the present invention can be realized only by incorporating the connection terminal portion 2 into the existing layout tray 1. In this case, the main part of the “reading unit” in the claims is constituted by the antenna 9 and the connection terminal unit 2. Further, the wireless tag reader 10 is not used while being fixed to the tray 1 for use, but the wireless tag 20 is read by the customer directly holding the wireless tag reader 10 and holding it on the dishes 6, 7, 8. Anyway.
In the above-described embodiment, the example in which the customer sets allergens in the wireless tag reader 10 in advance has been described. However, the touch panel is arranged on the display 11 of the wireless tag reader 10 and, for example, a “*” mark is displayed on the food with allergen information. Then, it is possible to use the wireless tag reader 10 configured to display the detailed information when it is touched via the touch panel on the display.

  In addition, each component of the wireless tag reader 10 shown in the above two embodiments can be provided as a program. Further, the program can be provided by being stored in various recording media (CD-ROM, flash memory, etc.). That is, a program for causing a computer to function as each unit of the wireless tag reader 10 and a recording medium on which the program is recorded are also included in the scope of rights of the present invention.

  Further, the system configuration of the information display system SY, the shape and function of the tray for tray 1 and the wireless tag reader 10, the place where the wireless tag 20 is attached to the tableware 6, 7, 8 and the package do not depart from the gist of the present invention.
