FIG. 1 is a diagram illustrating a system configuration of the layout system SY and an implementation example thereof. In the present embodiment, an example will be described in which a catering system SY is realized in a buffet restaurant (cafeteria, employee cafeteria, etc.).

  As shown in the figure, the serving system SY includes a serving tray 1 for placing tableware 6, 7, 8 (containers) on which ingredients (cooking, food, etc.) are placed, and the back surface of each tableware 6, 7, 8 It consists of an attached wireless tag 20 (see FIG. 4) and a weight measuring device 30 (information recording device) that measures the weight of each tableware 6, 7, and 8. 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 (tag ID) is recorded in ROM at the time of shipment from the manufacturer (hereinafter referred to as type 1), and a unique code + rewritable memory area is provided. There are three types of memory areas (hereinafter referred to as type 2) and those composed of rewritable memory areas (hereinafter referred to as type 3). In this embodiment, the rewritable memory areas of type 2 and type 3 The provided RFID is 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. The wireless tag reader 10 reads the wireless tag 20 attached to each tableware 6, 7, 8 and displays various information recorded on the wireless tag 20 on the display 11. Information stored in the wireless tag 20 includes a code (tag ID) for identifying the wireless tag 20 or a code (food material ID) for specifying individual ingredients, and a code (numerical value, symbol, String). In the following description, it is assumed that the wireless tag 20 stores a tag ID, a food material ID, and food material information.

  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 sold by weight, the price per tableware is determined based on the measurement result of the weight measuring device 30. It is done. Here, with regard to the ingredients sold by weight, the cooking staff in the kitchen places an appropriate amount on the tableware 6, 7, 8 and measures the weight of the tableware 6, 7, 8 by the weight measuring device 30. The weight measuring device 30 records food information such as a fee on the wireless tag 20 based on the measurement result. In addition, the weight measuring device 30 records food material information and the like on the wireless tag 20 in the same manner for foods having a uniform weight per tableware. However, in this case, since there is no need to measure the weight, only the information recording is performed without measuring the weight. Details will be described later. The cooking staff arranges the tableware 6, 7, 8 on which the information is recorded on the display shelf 31 in the store.

  On the other hand, the wireless tag reader 10 reads the wireless tags 20 of the dishes 6, 7, and 8 placed on the serving tray 1, and various information (tag ID, food name, weight, heat amount) held in the wireless tag 20. And charges) 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. 9), 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 location, the customer returns the serving tray 1 and the dishes 6, 7, and 8 to the predetermined return location in the same manner as a return method at a general buffet 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 of the serving system SY. Moreover, the cost required for system construction can be reduced also for the store side.

  Next, an external configuration of the weight measuring device 30 will be described with reference to FIG. The figure is an external perspective view of the weight measuring device 30.

The display 54 is a liquid crystal display device and displays the weight measurement result in grams. The operation key group 55 has a plurality of operation keys whose key names are food names, and the cooking staff presses the operation keys for the names of ingredients to be recorded before information recording. As a result, the food information of a plurality of types of foods (six types in the case of the illustrated weight measuring device 30) can be recorded by one weight measuring device 30. For example, when recording information on the wireless tag 20 of the tableware 6 on which “shrimp pilaf” is arranged as a foodstuff, the cooking staff presses the operation key “1. shrimp pilaf”. At this time, the lamp incorporated in the operation key is turned on to indicate that the operation key “1. Shrimp Pilaf” is in a selected state. In other words, if you want to continue recording information on the ingredients “shrimp pilaf”, you do not need to press the “1. shrimp pilaf” key each time, and after the information recording is complete (after confirming the buzzer sound) 6 can be placed. As described above, the weight measuring device 30 can record the weight measurement result and the food information while the tableware 6 is placed on the tableware placing unit 52 by the writer function incorporated in the tableware placing unit 52. It is possible.

  The weight measuring unit 33 measures the weight of the tableware 6, 7, 8 (foodstuff) placed on the tableware placing unit 52. In addition, although the weight measurement part 33 of this embodiment measures the weight of the foodstuff also including the weight of the tableware 6,7,8, when the foodstuff to serve on the tableware 6,7,8 is decided beforehand, the tableware 6 , 7, 8 may be subtracted so that only the weight of pure food can be measured.

  The buzzer 34 generates a buzzer sound (electronic sound) when information recording by the recording unit 38 is completed. The cooking staff can confirm that the information recording has been normally completed by the buzzer sound. Note that if information recording cannot be performed normally for some reason, a buzzer sound different from that during normal recording may be generated.

  The CPU 35 is a central control device that controls the entire weight measuring device 30. The ROM 36 stores various control programs for the CPU 35 to perform various arithmetic processes. Specifically, a calorie calculation program P1 for calculating the amount of heat of food per tableware and a charge calculation program P2 for calculating the price of food per tableware are stored. The RAM 37 stores the correspondence table T shown in FIG. 4 in a rewritable manner (storage unit) and is used as a work area for the CPU 35 to perform various arithmetic processes.

  As shown in FIG. 4, the correspondence table T stores “operation keys”, “food material IDs”, and “food material information” in association with each other. “Food material ID” is a unique code for specifying a food material. Further, in the present embodiment, as “food material information”, “food material name”, “heat amount (heat amount information)”, “fee (charge information)”, and “presence / absence of weight measurement” are stored. . For foods for which “Need to measure weight” is recorded as “Necessary”, “Amount of heat” and “Fee” are recorded in grams. In addition, for foods for which “existence of weight measurement” is recorded as “unnecessary”, “heat amount” and “fee” are recorded in units of dishes.

  Returning to the description of FIG. The recording unit 38 measures the measurement result by the weight measurement unit 33, the reference result of the correspondence table T by the CPU 35 based on the selection operation of the operation key group 55, and the calculation result (the amount of heat) using the heat calculation program P1 and the charge calculation program P2 by the CPU 35. Information and fee information) is recorded in the wireless tag 20. The recording unit 38 detects the placement of the tableware 6, 7, 8 on the tableware placement unit 52 and records information using this as a trigger. In this case, the reading of the tag ID from the wireless tag 20 may be used as a trigger, or the weight detection by the weight measuring unit 33 may be a predetermined amount or more.

  Next, with reference to FIG. 5, the control configuration of the tray for tray 1 (mainly, the wireless tag reader 10) will be described. FIG. 2 is a control block diagram of the tray 1 for serving. The tray for layout 1 includes a connection terminal portion 2, an antenna 9 (reading portion), and a wireless tag reader 10. The connection terminal unit 2 is a terminal for connecting the antenna 9 and the wireless tag reader 10 (communication unit 12). Although not particularly illustrated, the antenna 9 is disposed along the tray edge of the serving tray 1 so as to surround the dishes. In such a configuration, it is effective for the radio tag 20 having a low frequency, for example, about 130 KHz, and the radio of the tableware 6, 7, 8 placed inside the tray 1 is arranged along the tray edge. The tag 20 can be read reliably. The wireless tag reader 10 is connected to the connection terminal portion 2 by being set on a fixing / supporting portion (not shown) provided on the layout tray 1, and can communicate with the wireless tag 20 via the antenna 9. .

  On the other hand, the wireless tag reader 10 includes a communication unit 12, operation buttons 13, a display 11 (display unit), a CPU 15, a ROM 16, and a RAM 17. The communication unit 12 is connected to the connection terminal unit 2 of the tray body and is used for reading information from the wireless tag 20 attached to the dishes 6, 7, and 8. The operation button 13 is a push button type switch, and is used by a customer or a cashier person for various operations. The wireless tag reader 10 of this embodiment has two operation buttons (A button 13a and B button 13b, see FIG. 9). The A button 13a is a button for performing a settlement instruction, and the B button 13b is a button for performing information reset.

  The display 11 is a liquid crystal type display device, and displays various information including the reading result of the wireless tag 20. Specifically, each time the wireless tag 20 is read, the tag ID of the wireless tag 20, the ingredient name of the ingredient, the single item heat amount and the single item charge, and the total heat amount and total charge are displayed. Further, when a settlement instruction is given, the settlement information 60 (see FIG. 9) is displayed.

  The CPU 15 is a central control device that controls the entire tray 1 for serving. The ROM 16 stores various control programs for the CPU 15 to perform various arithmetic processes. Specifically, a calculation program for calculating the total amount of heat and the total charge of the food, a display control program (display control unit) for performing display control, a communication control program for performing communication control with the wireless tag 20, and the like (Both not shown). The RAM 17 is used as a work area for the CPU 15 to perform various arithmetic processes.

  Next, the operation of the weight measuring device 30 will be described with reference to FIG. This figure is a flowchart showing the information recording process of the weight measuring device 30. When any of the operation keys 55 in the operation key group 55 is pressed (S01: Yes), the weight measuring device 30 (CPU 35) acquires the food ID (identification information) corresponding to the operation key (S03, Identification information acquisition unit). Even if the operation key is not pressed (S01: No), if the placement of the dishes 6, 7, 8 on the tableware placement unit 52 is detected (S02: Yes), the operation key that has already been pressed. The foodstuff ID corresponding to is acquired (S03). And with reference to the corresponding | compatible table T, the foodstuff information matched with acquired foodstuff ID is extracted (S04, foodstuff information extraction part).

  Here, with reference to the item “Necessity of weight measurement” included in the food material information (see FIG. 4), in the case of a food material that requires weight measurement (S05: Yes), the weight measurement is performed (S06). Then, based on the weight measurement result and the “heat amount” and “fee” per unit weight read from the correspondence table T, the heat amount and fee per tableware are calculated (S07, heat amount calculation unit and charge calculation unit). After that, the “foodstuff name” read from the correspondence table T, the weight measured in S06, and the tableware calculated in S07 on the wireless tags 20 of the tableware 6, 7, and 8 placed on the tableware placement unit 52 The amount of heat and the charge are recorded (S08). When the recording is completed, a buzzer sound is generated by the buzzer 34 (S09).

  On the other hand, when the food does not require weight measurement (S05: No), the correspondence table T is placed on the wireless tag 20 of the tableware 6, 7, 8 placed on the tableware placement unit 52 without performing weight measurement. The “food material name”, “heat amount”, and “fee” read from the above are recorded (S10). Also in this case, when recording is finished, a buzzer sound is generated (S09).

  Next, the operation of the wireless tag reader 10 will be described with reference to FIGS. Both figures are flowcharts showing display processing of the wireless tag reader 10. As shown in FIG. 7, when the wireless tag reader 10 detects the wireless tag 20 attached to the tableware 6, 7, 8 as the customer places the tableware 6, 7, 8 on the serving tray 1 ( (S11: Yes), various information recorded on the wireless tag 20 (tag ID, food name, weight, amount of heat, information on charges) is acquired (S12). 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 tray 1 is one item (S13). 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 S13 that the item is one item (S13: Yes), the amount of heat read from the wireless tag 20 (single item amount of heat) is set as the total amount of heat, and the rate read from the wireless tag 20 (single item rate) is set as the total amount ( S14). In addition, these single item heat quantity and single item charge, and the total heat quantity and total charge are displayed on the display 11 (S15). On the other hand, if it is determined that it is not one item (two items or more) (S13: No), the heat amount (single item heat amount) and fee (single item fee) read from the wireless tag 20 are added to the total heat amount and the total charge so far. These are added to obtain the total heat amount and total charge (S16), and these values are displayed on the display 11 (S15).

  Further, as shown in FIG. 8, when it is detected that the settlement button (A button 13a, see FIG. 9) is pressed (S17: Yes), all the dishes 6, 7, 8 placed on the tray 1 for serving are arranged. The wireless tag 20 is re-read and the total heat amount and total charge are recalculated (S18), and the settlement information 60 is displayed (S19). Further, when pressing of the reset button (B button 13b, see FIG. 9) is detected (S20: Yes), the read information stored in the predetermined area of the RAM 17 is erased and the display 11 display is set to the initial state. (S21).

  Next, display contents displayed on the display 11 of the wireless tag reader 10 will be described with reference to FIG. FIG. 9 is a diagram illustrating an example of a checkout screen displayed on the wireless tag reader 10 after three foodstuffs are placed on the tray 1 and the A button 13a is pressed. Here, as the settlement information 60, single item information 61 that is information for each ingredient, total information 62 that is information based on all the read ingredients, and a two-dimensional code 63 are displayed.

  As the single item information 61, the tag ID read from the wireless tag 20, the name of the ingredient, the single item calorie, and the single item charge are displayed. Here, when “weight” is included in the information read from the wireless tag 20, the weight is written in parentheses in the food name. Further, as the total information 62, the total number of read ingredients, total heat amount, and total charge are displayed. 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. The wireless tag reader 10 rereads the wireless tag 20 and recalculates the total heat amount and the total fee when the A button 13a is pressed, so that the cashier person finally presses the A button 13a. Thus, reading omission of the wireless tag 20 can be prevented.

  As described above, according to the weight measuring apparatus 30 of the present embodiment, the correspondence table T in which the operation key and the food information are associated with each food is stored, and the food information associated with the operation key is stored. Since recording is performed on the wireless tag 20, it is possible to record food information of a plurality of types of foods with a single device. Thereby, since it is not necessary to install the information recording device by the number of types of foodstuffs, the problem of installation cost and installation space can be solved.

  In addition, according to the wireless tag reader 10 of the present embodiment, the food material information related to the amount of heat is read from the wireless tag 20 attached to the tableware 6, 7, 8, and the total heat amount of all the food materials on the serving tray 1 is obtained. Since it is calculated and displayed, the customer can easily check the total amount of heat simply by placing the dishes 6, 7, 8 on the serving tray 1. Thereby, in the restaurant of a buffet system, since a foodstuff can be selected, confirming total calorie | heat amount, it is convenient for the user who cares about health and a diet.

  Note that the weight measuring device 30 in the above embodiment specifies the food information of the food to be recorded by operating the operation key group 55 (acquires a selection result based on the selection operation of the operation key group 55 as identification information). However, the food information may be specified by acquiring tag information recorded in advance on the wireless tag 20. In this case, it is assumed that the weight measuring device 30 has a reading function of the wireless tag 20. For example, when the ingredients to be arranged on the dishes 6, 7, and 8 are determined in advance, the ingredient ID is recorded in advance as tag information (identification information) on the wireless tag 20 of the dishes 6, 7, and 8. The weight measuring device 30 reads the food ID when the tableware 6, 7, 8 is placed on the tableware placement unit 52. Then, the food information is specified with reference to the correspondence table T (see FIG. 4). As described above, since one food material information to be recorded can be specified from the tag information pre-recorded in the wireless tag 20, it is possible to continuously read the tag information and record the food information, and quickly Information recording processing can be performed.

  As another method, it is possible to use the above-described type 1 RFID that does not have a rewritable memory. In this case, it is assumed that the weight measuring device 30 and the wireless tag reader 10 are connected via a wired or wireless network. First, the weight measuring device 30 reads the tag ID as tag information when the tableware 6, 7, 8 is placed on the tableware placement unit 52. And the foodstuff information specified by the operation of the operation key or the like is stored in the database in the server connected to the weight measuring device 30, the wireless tag reader 10, or both in association with the read tag ID. The wireless tag reader 10 reads the tag ID from the wireless tag 20, reads the food material information associated with the tag ID from the database, and displays the information. According to this configuration, the writer function can be omitted from the weight measuring device 30, and an inexpensive RFID of type 1 can be used.

  In the above embodiment, the case where the calorie information and the charge information are recorded in the wireless tag 20 as the food material information is exemplified. However, the content information related to the food content may be recorded. As the content information, for example, “information on allergen substance” may be recorded. In this case, the weight measuring device 30 stores in the correspondence table T the allergen substances contained in the food contents in association with each other. Then, the wireless tag reader 10 determines whether or not the allergen substance is included from the read food material information, and if included, the contents and the allergen substance are displayed or output by the two-dimensional code 63 or the like. Or That is, as the content information, information in which the allergen substance is associated with the content including the material (including ingredients and seasonings) is read. Allergen substances include allergen-required items (egg, milk, wheat, buckwheat, peanut), or allergen-recommended items (abalone, squid, how much, shrimp, orange, crab, kiwifruit, beef, It is preferable to target walnuts, salmon, mackerel, soybeans, chicken, pork, matsutake, peaches, yam, apples, gelatin, and bananas. Also, in this case, allergen substances that should be noted are set in the wireless tag reader 10 from the above-mentioned obligatory items or recommended items, and only the set allergen substances and contents containing them are extracted and displayed.
