In this way, according to the settlement system, the burden of business on the clerk can be reduced by using the computer for the settlement work.

Patent document 1: japanese patent laid-open No. 2008-3926

Disclosure of Invention

However, in this settlement system, the RFID11 is attached to each product tray 10. Therefore, it is necessary to stack a plurality of product trays 10 on a customer's table until the customer acquires order data (food consumption), that is, until the customer finishes eating. Therefore, there is a problem that the dining table is messy, and not only the customer is not comfortable, but also the dining table space is reduced.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a settlement system capable of reducing the burden of business on a clerk using a computer and removing a dish after eating from a dining table before settlement by a customer.

To achieve the object, a settlement system according to the present invention includes: a label provided with the customer's dish; a reading unit that reads the contents of the tag; an identification unit that identifies information related to a dish consumed by a customer according to a reading result of the reading unit; and a settlement unit configured to settle a fee of the customer based on a result of the identification by the identification unit, wherein the reading unit, the identification unit, and the settlement unit are executed by a computer, wherein the tag is configured to be separable from a dish and a dish plate containing the dish, the reading unit reads the content of the tag separated from the dish and the dish plate at a customer seat, and the dish plate eaten by the customer can be removed from the customer's table before settlement by the settlement unit.

According to the settlement system of the first aspect, the contents of the tags provided with the dishes of the customer are read by the reading unit, and information related to the dishes consumed by the customer is identified by the identifying unit according to the reading result. Further, the customer's fee is settled by a settlement unit based on the identification result. Since these are executed by a computer, the business burden of the clerk can be reduced. The tag is configured to be separable from a dish and a dish plate containing the dish, and the reading unit reads the content of the tag separated from the dish and the dish plate at the customer seat. Thus, the dish consumed by the customer can be removed from the customer's table before the payment is settled by the settlement unit. Therefore, the dining table is not cluttered or the dining table space is not reduced due to the edible dinner plate. Further, as the information related to the dish, for example, the content of the dish, the amount of money of the dish, a code assigned to the dish or the amount of money can be exemplified.

According to the settlement system of the second aspect, in addition to the effects of the first aspect, the following effects are also obtained. An adhesive sheet to which a plurality of labels can be attached is provided at the customer seat, and the reading means reads the label attached to the adhesive sheet at the customer seat to display the label. Therefore, the customer can grasp the eating condition by visually checking the label attached to the attachment plate. That is, the customer can eat while grasping the eating condition.

The settlement system according to the third aspect has the following effects in addition to the effects of the second aspect. The identification unit identifies information related to the dish by image-recognizing the display of the tag read by the reading unit, and displays the contents of the dish in characters or patterns on the surface of the tag so that the customer can grasp the contents of the dish by visual confirmation. Therefore, the customer can grasp not only the eating status but also the eating contents by visually checking the label attached to the attachment plate.

According to the settlement system of the fourth aspect, in addition to the effects of the third aspect, the following effects are also obtained. The identification unit identifies information related to the dishes according to characters displayed in the label. Characters displayed on the label are simple and stable in shape compared with patterns. The character is recognized through image processing, so that information related to dishes can be recognized accurately and rapidly.

According to the settlement system of the fifth aspect, in addition to the effects of the third aspect, the following effects are also obtained. The identification unit does not identify the information related to the dishes when foreign matters except the adhesive plate and the label exist in the reading result of the reading unit. Thus, it is possible to suppress an error in the identification of the information relating to the dish due to the foreign matter, and thus it is possible to improve the accuracy of the identification of the information relating to the dish.

The settlement system according to the sixth aspect has the following effects in addition to the effects of the second aspect or the third aspect. The label is formed in a non-circular shape in a plan view, and the contour line of the label formed in the non-circular shape is displayed on the surface of the adhesive sheet in the form of a frame line indicating the position where the label is to be attached. Therefore, the label can be attached to the position where the frame line is displayed in a state of the same direction, and thus, the information related to the dish can be easily identified by the identification unit.

The settlement system according to the seventh aspect has the following effects in addition to the effects of the second aspect or the third aspect. The benefit giving unit gives a benefit to the customer when a state in which the plurality of labels are attached to the attachment plate satisfies a predetermined condition. Therefore, it is possible to provide entertainment to the attaching operation of attaching the label to the attaching plate, thereby promoting the attaching operation of the customer. In addition, as the benefit given to the customer, a discount service of a fee, a discount coupon, a dish, a small gift, or the like can be exemplified.

According to the settlement system of the eighth aspect, in addition to the effects of the second aspect or the third aspect, the following effects are also obtained. The mounting table mounts the adhesive sheet so that the label attached to the adhesive sheet is positioned in a reading range of the reading unit. Therefore, by simply placing the attachment plate on the placement table, the label attached to the attachment plate can be reliably read by the reading means. The mounting table can stack and mount a plurality of adhesive sheets. Therefore, when the amount of dishes consumed by the customer is large and it is not possible to attach all the labels to one adhesive sheet, the plurality of adhesive sheets are stacked on the mounting table, and the space of the dining table of the customer seat is not reduced by the adhesive sheet. That is, the space of the customer's table can be secured.

The settlement system according to the ninth aspect has the following effects in addition to the effects of any one of the first to third aspects. The settlement unit settles the items ordered by the input unit provided at the customer seat and eaten by the customer together with the customer fee calculated from the reading result of the reading unit and the identification result of the identification unit. That is, the label-based diet and the diet of the input means based on the customer seat can be settled together.

Detailed Description

Hereinafter, preferred embodiments will be described with reference to the drawings. First, referring to fig. 1 and 2, the structure of the computing system 100 will be described. Fig. 1 is a diagram showing a configuration of a settlement system 100 according to an embodiment of the present invention. Fig. 2 (a) is a perspective view of the dish 3 in which the dish F and the label 4 are placed, and fig. 2 (b) is a plan view of the sticker sheet 11 in which the label 4 is stuck.

As shown in fig. 1 and 2, the settlement system 100 is a system for performing settlement (checkout) processing in a restaurant (a hot pot restaurant in the present embodiment). In the settlement system 100, a customer who has mainly eaten at a customer seat 1 takes out a dish 3 from the transportation path 2, and reads a tag 4 placed on the dish 3 together with a dish F (food) by using a portable terminal 5 (tablet computer), thereby performing settlement processing of the food.

In a restaurant, a plurality of customer seats 1 are arranged in a row along a conveying direction of a conveying path 2. In the present embodiment, the description is given of the case where one customer takes a meal at one customer seat 1, but a configuration may be adopted in which a plurality of customers take a meal at the customer seats 1.

The conveyance path 2 is provided adjacent to the customer seat 1 on the front side as viewed from the customer seated in each customer seat 1. The conveyor path 2 is a conveyor for conveying the dishes 3 with the dishes F placed thereon to the customer seats 1, and a known configuration can be adopted, and thus detailed description thereof is omitted.

A dish F and a label 4 on which contents (for example, information on the type and quantity of meat) of the dish F are recorded are placed on the dish 3 conveyed by the conveyance path 2. The dish F is cooked by the cooker 10 provided at the customer seat 1 and consumed by the customer. On the other hand, the label 4 is adhered to the adhesive sheet 11 so as to read the contents of the dish F eaten by the customer with the portable terminal 5.

The adhesive sheet 11 is formed of a metal material into a rectangular plate shape, and a magnet is provided on the back surface of the label 4. Therefore, by placing the label 4 taken (separated) from the dish 3 on the adhesive sheet 11, the label 4 can be easily adhered to the adhesive sheet 11.

Each customer seat 1 is provided with a mounting table 12 on which the adhesive sheet 11 is mounted. The mounting table 12 includes a mounting portion 12a on which the adhesive sheet 11 is mounted, and a holder 12b for holding the mobile terminal 5 so as to face the mounting portion 12 a. Each customer seat 1 is provided with one of the placement tables 12.

The holder 12b protrudes upward from an edge portion of the mounting portion 12a, and the portable terminal 5 is detachably fixed to a protruding distal end side thereof. The mobile terminal 5 is provided with a camera, and the upper surface of the adhesive sheet 11 (the surface to which the label 4 is attached) placed on the placement portion 12a is in a state in which the mobile terminal 5 is fixed to the holder 12b, and the camera lens of the mobile terminal 5 face each other. Therefore, the contents (information) of the label 4 attached to the attachment plate 11 can be read (photographed) by the portable terminal 5.

On the surface of the label 4 is displayed a character string representing the content of the dish F placed on the dinner plate 3. For example, dish F shown in fig. 2 (a) is pork rib meat, and thus a character string of "pork rib meat 40 g" is displayed in label 4.

In addition, the surface of the label 4 is painted with a pattern corresponding to the contents of the dish F. For example, as shown in fig. 2 (b), a cow is marked on the label 4 of "cow tongue root 40 g", and a pig is marked on the label 4 of "pig rib meat 40 g". Further, the background of the character string and the pattern displayed on the label 4 is colored in different colors according to the contents of the dish F. For example, label 4 of "taupe root 40 g" is colored pink and label 4 of "pork rib meat 40 g" is colored red.

Thus, by image-recognizing the display (character string in the present embodiment) of the tag 4 photographed by the mobile terminal 5, it is possible to recognize (discriminate) information (contents of the dish F in the present embodiment) related to the dish F eaten by the customer, and to settle the fee of the customer based on the recognition result. The recognition and settlement processing of these images is executed by the image recognition server 7 and the POS server 8 (see fig. 5) described later. That is, since the operation of reading the information of the tag 4 by the clerk going to the customer seat 1 is not required, the burden of the clerk on the business can be reduced.

Further, the dish F, the dish plate 3 containing the dish F, and the label 4 can be separated, and the payment can be settled according to the information of the separated label 4. This enables the dinner plate 3 after meal to be removed from the table of the customer seat 1 before settlement. Therefore, the dining table of the customer seat 1 is not cluttered or the dining table space is not reduced by the dinner plate 3 after eating.

Further, the customer seat 1 is provided with an adhesive sheet 11 to which a plurality of labels 4 can be attached, and the label 4 attached to the adhesive sheet 11 is read and displayed on the customer seat 1. This allows the customer to visually confirm the number of adhesive sheets 11 and the number of labels 4 attached to the adhesive sheets 11 during a meal. Therefore, the customer can eat and drink while grasping the eating status of how much the customer has eaten and drink.

In this way, the content of the dish F eaten by the customer is recognized by image-recognizing the display of the tag 4, and the display of the tag 4 for this image-recognition is a character string representing the content of the dish F. Therefore, the customer can grasp the contents of the dish F by visually confirming the character string displayed on the label 4. Therefore, the customer can visually confirm the label 4 attached to the attachment plate 11, and can grasp which dishes F are eaten in addition to the above-described eating conditions.

Further, since the character string or the pattern indicating the contents of the dish F is displayed on the label 4, the customer can easily determine what dish F is placed on the dish 3 conveyed on the conveyance path 2. That is, the character string or pattern of the tag 4 can be made to have a function for image recognition and a function of notifying the customer of the content of the dish F.

In addition, the adhesive sheet 11 is configured to be entirely received within the imaging range of the camera of the mobile terminal 5 in a state where the adhesive sheet 11 is placed on the placement portion 12a of the placement table 12 and the mobile terminal 5 is fixed to the holder 12 b. Thus, only by attaching the label 4 to the adhesive sheet 11 placed on the placement portion 12a of the placement table 12, the label 4 attached to the adhesive sheet 11 can be reliably imaged by the mobile terminal 5. That is, when photographing the label 4, it is not necessary to adjust the positional relationship between the attachment plate 11 and the mobile terminal 5 or to pick up the mobile terminal 5, and therefore, the label 4 can be easily photographed.

The placement portion 12a of the placement table 12 is formed in a box shape capable of accommodating the attachment plate 11 in a stacked state. Thus, when the number of labels 4 stuck to the sticking plate 11 reaches the upper limit of 9, a new sticking plate 11 can be stacked. Therefore, when the amount of dishes consumed by the customer is large and it is not possible to attach all the labels 4 to one adhesive sheet 11, the plurality of adhesive sheets 11 are stacked on the placement portion 12a, so that the dining room space of the customer seat 1 is not reduced by the adhesive sheets 11. That is, the space of the customer's table can be secured.

The label 4 is formed into a substantially circular plate shape as a whole, and a part of the outer edge of the label 4 is formed as a corner portion 4a (the label 4 is formed into a droplet shape as a whole). The corner portion 4a is formed in a wedge shape protruding toward the radial direction of the label 4. Therefore, the posture of the tag 4 can be stabilized by inserting the corner 4a into the dish F (meat) (see fig. 2 (a)). On the other hand, the corner portion 4a also functions as a positioning portion when the label 4 is attached to the adhesive sheet 11.

The adhesive sheet 11 has a plurality of (9 portions in 3 rows × 3 columns in the present embodiment) adhesive areas 11a for attaching the labels 4 (see fig. 2 (b)). The pasting region 11a is formed by a frame line drawn on the pasting board 11 in the same shape as the outline of the label 4, and the corner 11b is also formed in the pasting region 11a in the same manner as the label 4. The adhesive areas 11a are arranged on the adhesive sheet 11 so that the corner portions 11b face the same direction (below the adhesive sheet 11).

Thus, by attaching the labels 4 along the frame line of each attachment area 11a, the plurality of labels 4 can be attached to the attachment plate 11 in a state in which the vertical directions thereof are aligned. Therefore, the image can be captured by the mobile terminal 5 in a state in which the orientations of the character strings of the respective tags 4 are aligned, and thus the image recognition can be easily performed. That is, even in a state where the labels 4 are not attached along the frame line of the attachment area 11a (the vertical directions of the labels 4 do not coincide), the information of the labels 4 can be recognized by image recognition, but by aligning the vertical directions of the labels 4, the recognition accuracy and the processing speed of the image recognition can be improved.

In the present embodiment, when the state of attachment of the label 4 in the attachment area 11a of the attachment plate 11 satisfies a predetermined condition, a customer is given a preference. Specifically, as shown in fig. 2 (b), three labels 4 in the leftmost column in 9 pasting regions 11a of 3 rows × 3 columns in the pasting sheet 11 are all drawn in a bovine pattern. That is, when the same patterns are aligned in a row and such a state is recognized by image recognition, a discount coupon for a fee (fee discount at the time of settlement) is issued (see fig. 3 (c)).

This gives entertainment to the sticking operation of the label 4 to the sticking plate 11, and promotes the sticking operation of the customer. That is, although the operation corresponding to reading of the tag 4 is performed by a clerk at present, the operation is performed by a customer in the present embodiment. On the other hand, by providing entertainment to the operation of reading (image recognition) the tag 4, the operation can be positively performed without being bothered.

Further, in fig. 2 (b), the case where the discount coupon is given when the patterns are aligned in a column in the vertical direction is explained, but the discount coupon is also given when the patterns are aligned in a column in the horizontal direction or aligned in a column in the diagonal direction. That is, the larger the number of rows in which the patterns are aligned, the higher the discount rate, and therefore, the entertainment of the work of attaching the label 4 to the attachment plate 11 can be further improved.

Further, the top surface of the adhesive sheet 11 is provided with a sheet number 11c for identifying each adhesive sheet 11. The plate number 11c is a number for managing information of the labels 4 for each of the adhesive sheets 11 when the labels 4 are adhered to the adhesive sheets 11.

In this way, in the present embodiment, increase or decrease of the labels 4 attached to the attachment plate 11 is recognized by image recognition, and a benefit is given based on the recognition result. A screen displayed on the mobile terminal 5 when an increase or decrease of the tag 4 is recognized or when a benefit is given will be described with reference to fig. 3. Fig. 3 (a) is a schematic view of a screen displayed on the LCD57 when the label 4 on the attachment plate 11 is added. Fig. 3 (b) is a schematic view of a screen displayed on the LCD57 when the label 4 on the attachment plate 11 is reduced. Fig. 3 (c) is a schematic diagram showing a screen displayed on the LCD57 when a discount coupon is issued.

As shown in fig. 3 (a) and (b), when the number of labels 4 attached to the attachment plate 11 increases or decreases, an addition confirmation screen 57a (see fig. 3 (a)) for confirming that a customer has added a label 4 to the attachment plate 11 and a deletion confirmation screen 57b (see fig. 3 (b)) for confirming that the label 4 has been removed are displayed on the LCD57 (liquid crystal display device) of the mobile terminal 5. The addition confirmation screen 57a and the deletion confirmation screen 57b display an OK button 57c and a cancel button 57d for the customer to determine whether the increase or decrease of the label 4 is correct, in addition to information indicating the image of the label 4 (dish F) to be increased or decreased and the price.

When the OK button 57c is operated, the increase or decrease of the label 4 displayed on the addition confirmation screen 57a or the deletion confirmation screen 57b is reflected in the settlement processing. On the other hand, when the cancel button 57d is operated, the increase or decrease is not reflected in the settlement processing. This prevents settlement processing from being performed at an incorrect fee.

As shown in fig. 3 (c), when the discount coupon is attached by attaching the label 4 to the attachment plate 11, an addition confirmation screen 57e for confirming that the discount coupon is added (applied) is displayed. When the addition confirmation screen 57e is displayed, a sound (sound, music) notifying that the discount coupon is added is output. In this way, by notifying the result of identification (increase or decrease) of the label 4 and notifying the preferential application based on the identification result, it is possible to improve the entertainment of the work of attaching the label 4 to the attachment plate 11.

In addition, the LCD57 displays a menu button 57f, a placing history button 57g, and a checkout button 57 h. A screen displayed on the mobile terminal 5 when these buttons are operated will be described with reference to fig. 4. Fig. 4 (a) is a schematic diagram of a screen displayed on the LCD57 when the menu button 57f is operated. Fig. 4 (b) is a schematic diagram of a screen displayed on the LCD57 when the order history button 57g is operated. Fig. 4 (c) is a schematic diagram of a screen displayed on the LCD57 when the checkout button 57h is operated.

As shown in fig. 4 (a), when the menu button 57f on the LCD57 is operated, a screen for ordering meat, soup, single-point dishes, beverages, and the like from the portable terminal 5 is displayed. In the example shown in fig. 4 (a), the drink button 57i is operated, and a screen for selecting a drink to be ordered is displayed.

Here, when a menu of meat is ordered from the portable terminal 5, the ordered dish F is supplied to the customer seat 1 through the transportation path 2 (see fig. 1) together with the label 4. On the other hand, in the case where a beverage is ordered, only the beverage is directly provided to the customer seat 1 by a clerk, and the label 4 is not provided to the customer. Therefore, in the case where a beverage is ordered from the portable terminal 5, the time point of placing an order on the LCD57 is reflected in the following settlement processing. This makes it possible to settle the fee of the beverage ordered (placed) from the portable terminal 5 and the fee of the dish F calculated based on the image recognition of the tag 4.

As shown in fig. 4 (b), when the order history button 57g on the LCD57 is operated, an order history screen 57j indicating the diet fee at the current time is displayed. Since the information (type and number) of the dishes F consumed is displayed on the order history screen 57j, the customer can confirm whether or not the diet result displayed on the order history screen 57j is incorrect, as compared with the label 4 attached to the attachment plate 11. Therefore, the reliability of the subsequent settlement processing can be improved.

As shown in fig. 4 (c), when the checkout button 57h on the LCD57 is operated, a settlement screen 57k indicating the total amount of the fee to be settled is displayed. The settlement screen 57k displays a barcode 57l for performing settlement processing by a settlement device 86 (see fig. 5) to be described later. Thus, the customer can place the adhesive sheet 11 (label 4) on the customer seat 1, and can carry out settlement processing by taking only the portable terminal 5 to the settlement device 86 and presenting the barcode 57 l. Therefore, for example, the clerk is not required to go to the customer seat 1 to issue the barcode 57l, and thus the burden of the clerk on the business can be reduced.

Next, an electrical configuration of the computing system 100 will be described with reference to fig. 5. Fig. 5 is a block diagram showing an electrical configuration of the settlement system 100.

As shown in fig. 5, the settlement system 100 is composed of a plurality of mobile terminals 5, an AP6 as a wireless LAN access point wirelessly connected to the plurality of mobile terminals 5, an image recognition server 7 connected to the AP6, and a POS server 8.

The image recognition server 7 is a server mainly used for analyzing information of the tag 4 (see fig. 2) from the image captured by the mobile terminal 5. The POS server 8 is a server mainly used for performing settlement processing based on the information (the amount of food consumed by the customer) of the tag 4 analyzed by the image recognition server 7.

Each mobile terminal 5 includes a CPU50, a flash ROM51, and a RAM52, and is connected to the input/output port 54 via a bus 53. The input/output port 54 is connected to a camera 55, a touch panel 56 for operating on the LCD57, an LCD57, and a wireless communication device 58, respectively. The CPU50 is an arithmetic device that controls each unit connected via the bus 53.

The flash ROM51 is a rewritable nonvolatile memory. The flash ROM51 stores therein the terminal control program 51a, the terminal ID data 51b, and the menu code table 51 c. When the terminal control program 51a is executed by the CPU50, the terminal main process of fig. 7 described later is executed.

The terminal ID data 51b stores ID information of the portable terminal 5. That is, independent ID information (T1, T2, etc.) is given to each mobile terminal 5, and the amount of food consumed by the customer is managed for each mobile terminal 5, that is, each customer seat 1, based on the ID information (settlement processing).

The menu code table 51c is a data table storing menu codes assigned to the dishes F provided by the restaurant. The menu code table 51c is referred to when adding/deleting a menu code to/from the subscription table 52a of the RAM 52.

The RAM52 is a volatile memory that rewritably stores various operation data, flags, and the like when the CPU50 executes programs such as the terminal control program 51 a. The RAM52 is provided with a purchase table 52a for storing information on a dish F consumed by the customer. Here, the menu code table 51c and the order table 52a will be described with reference to (a) and (b) of fig. 6.

Fig. 6 (a) is a schematic diagram of the menu code table 51c, and fig. 6 (b) is a schematic diagram of the order table 52 a. As shown in fig. 6 (a), the menu code table 51c stores menu codes corresponding to trade names of the dish F. That is, the dishes F provided to the restaurant are respectively given menu codes corresponding to the kinds and amounts of the dishes F. For example, a menu code of "1001" is given to the pig back 40g, and a menu code of "1012" is given to the pig rib meat 50 g. Further, the beer is given a menu code of "5001", and the discount coupon is given a menu code of "9001".

As shown in fig. 6 (b), the order table 52a is a data table for storing menu codes of the dish F consumed by the customer. The order table 52a stores menu codes (product names and numbers) of dishes F consumed by the customer. For example, in the example of fig. 6 (b), "4" is stored in the table of No.1 as the number of pig ridges 40g having the menu code "1001", and "2" is stored in the table of No.10 as the number of draught beer having the menu code "5001".

Further, as described above, with respect to the dish F provided together with the tag 4, the menu code is added to the order table 52a according to the resolution of the tag 4. On the other hand, when ordering a part of the products (for example, beverages) ordered by the operation of the mobile terminal 5, the menu code is added to the order table 52a along with the ordering.

The explanation will be made with reference to fig. 5. The portable terminal 5 is connected to the AP6 via the wireless communication device 58. The image of the tag 4 captured by the camera 55 of the portable terminal 5 is transmitted to the image recognition server 7 via the AP 6.

The image recognition server 7 includes a CPU70, an HDD71, and a RAM72, and is connected to the input/output port 74 via a bus 73. The input/output port 74 is connected to a communication device 75, and the image recognition server 7 is connected to the AP6 via the communication device 75.

The CPU70 is an arithmetic device that controls each unit connected via the bus 73. The HDD71 is a rewritable nonvolatile storage device that stores programs executed by the CPU70, fixed value data, and the like. The HDD71 stores therein an image recognition control program 71a and a menu code table 71 b. When the image recognition control program 71a is executed by the CPU70, the image recognition processing of fig. 9 described later is executed. The configuration of the menu code table 71b is the same as that of the menu code table 51c (see fig. 6 (a)) of the mobile terminal 5, and therefore, detailed description thereof is omitted.

The RAM72 is a volatile memory that rewritably stores various operation data, flags, and the like when the CPU70 executes programs such as the image recognition control program 71 a. The RAM72 is provided with a read result table 72a and a terminal ID memory 72 b.

The read result table 72a is a data table for storing information of the tag 4 analyzed by image recognition, and the terminal ID memory 72b is a memory for storing ID information of the portable terminal 5 that transmits an image to the image recognition server 7. Here, the read result table 72a will be described with reference to fig. 6 (c).

Fig. 6(c) is a schematic diagram of the read result table 72 a. As shown in fig. 6(c), the read result table 72a stores the type and number of dishes F read from the image (tag 4) captured by each portable terminal 5 for each board number. This is because: as described above, when the number of labels 4 attached to the attachment plate 11 reaches the upper limit, there is a case where the labels 4 are attached to a new attachment plate 11 and the labels 4 are managed for each attachment plate 11.

For example, in the example of fig. 6(c), as a result of reading the image transmitted from the mobile terminal 5 having the terminal ID T1, information (menu code, product name, number) of the label 4 attached to the attachment plate 11 having the plate number "1" is stored in the tables of nos. 1 to 9, and information of the label 4 attached to the attachment plate 11 having the plate number "2" is stored in the tables of nos. 10 to 18.

The explanation will be made with reference to fig. 5. The POS server 8 includes a CPU80, an HDD81, and a RAM82, and is connected to the input/output port 84 via a bus 83. The input/output port 84 is connected to a communication device 85 and a settlement device 86. The communication device 85 is a device for connecting the POS server 8 to the AP6, and the settlement device 86 is a device for managing settlement of fees and payment of customers.

The CPU80 is an arithmetic device that controls each unit connected via the bus 83. The HDD81 is a rewritable nonvolatile storage device that stores programs executed by the CPU80, fixed value data, and the like. The HDD81 stores a POS control program 81a, a menu code table 81b, and a settlement management table 81 c.

When the POS control program 81a is executed by the CPU80, POS main processing of fig. 10 described later is executed. The RAM82 is a volatile memory that rewritably stores various operation data, flags, and the like when the CPU80 executes programs such as the POS control program 81 a. The configuration of the menu code table 81b is the same as that of the menu code table 51c (see fig. 6 (a)) of the mobile terminal 5, and therefore, detailed description thereof is omitted.

The settlement management table 81c is a data table for storing information on the dish F to be eaten at the customer seat 1 where each portable terminal 5 is placed. Here, the calculation management table 81c will be described with reference to fig. 6 (d).

Fig. 6 (d) is a schematic diagram of the settlement management table 81 c. As shown in fig. 6 (d), the settlement management table 81c stores the type and number of dishes F to be eaten at the customer seat 1 for each terminal ID of the portable terminal 5. For example, in the example of fig. 6 (d), as the dish F to be eaten at the customer seat 1 where the portable terminal 5 having the terminal ID of T1 is placed, the number "4" of the pig back 40g having the menu code of "1001" is stored in the table of No.1, and the number "2" of the draught beer having the menu code of "5001" is stored in the table of No. 10. Settlement processing is performed for each customer seat 1 on which each portable terminal 5 is placed, based on the information stored in the settlement management table 81 c.

The explanation will be made with reference to fig. 5. The tag 4 imaged by the mobile terminal 5 is analyzed by the image recognition server 7, and the analysis result is temporarily transmitted to the mobile terminal 5. That is, when the image recognition server 7 analyzes the tag 4, the image recognition server 7 sends an instruction to the mobile terminal 5 to add the menu code of the dish F corresponding to the tag 4 to the order table 52 a. The judgment as to whether the instruction is correct is made by the operation performed by the customer in the mobile terminal 5 as described above (see fig. 3 (a) and 3 (b)).

If it is determined that the instruction is correct, the menu code of the dish F corresponding to the analyzed tag 4 is stored in the order table 52a of the mobile terminal 5 and the read result table 72a of the image recognition server 7. Then, an instruction is sent from the portable terminal 5 to the POS server 8 to add the menu code to the settlement management table 81 c. The terminal ID memory 82a provided in the POS server 8 is a memory for storing ID information of the mobile terminal 5 instructed to the POS server 8.

Next, with reference to fig. 7 and 8, a process executed by the CPU50 of the mobile terminal 5 will be described. Fig. 7 is a flowchart of the terminal main process, and fig. 8 is a flowchart of the subscription process. The terminal main process is a process executed when an execution instruction of the terminal control program 51a is input from the touch panel 56.

As shown in fig. 7, in the terminal main process, it is first confirmed whether or not an initialization instruction is input to the mobile terminal 5 (S1). The initialization instruction is a process for bringing the mobile terminal 5 into a state in which it can accept orders from new customers, and if the initialization instruction is not input (no in S1), the processes from S2 to S4 are skipped. The initialization instruction may be input by a clerk operating the mobile terminal 5, or may be automatically input when a new customer uses the mobile terminal 5 (the previous customer has finished using the mobile terminal 5).

On the other hand, when the initialization instruction is input to the mobile terminal 5 (S1: YES), the initialization instruction is given to the image recognition server 7 and the POS server 8 (S2). The initialization instruction is an instruction for clearing the data of the read result table 72a of the image recognition server 7 and the settlement management table 81c of the POS server 8.

After the process at S2, subscription table 52a is initialized (S3), and subscription reception is started (S4). This allows the order of a customer who newly uses the mobile terminal 5 to be accepted.

After the process of S4, it is confirmed whether or not the order is being accepted (S5). If the order is not being accepted (NO at S5), the process of S6 and S7 is skipped. On the other hand, when the order is accepted (YES in S5), the image captured by the camera 55 is transmitted to the image recognition server 7 (S6). After the process of S6, a subscription process is performed (S7). This order processing (S7) will be described with reference to fig. 8.

As shown in fig. 8, in the order process (S7), it is first confirmed whether or not an instruction is received from the image recognition server 7 (S20). That is, as described above, for example, when it is determined by the analysis in the image recognition server 7 that the number of the labels 4 on the attachment plate 11 has increased or decreased, an instruction is transmitted from the image recognition server 7 to the mobile terminal 5 to add the menu code corresponding to the increased or decreased label 4 to the order table 52a or delete the menu code from the order table 52 a.

When an instruction to add a menu code is received from the image recognition server 7 (S20: addition instruction), the addition confirmation screens 57a and 57e (see fig. 3) are displayed on the LCD57 (S21). After the process of S21, it is confirmed which of the above-described OK button 57c or cancel button 57d is operated (S22). When the cancel button 57d is operated (S22: cancel), it is considered that the label 4 actually stuck to the sticking plate 11 by the customer does not match the analysis result of the label 4 in the image recognition server 7, and a cancel instruction is transmitted to the image recognition server 7 (S23). On the other hand, when the OK button 57c is operated (S22: OK), an OK instruction is transmitted to the image recognition server 7 (S24).

After the process of S24, the menu code for which the addition instruction is received from the image recognition server 7 is added to the purchase table 52a (S25). Then, in order to reflect the addition of the menu code in the processing of S25 in the settlement management table 81c of the POS server 8, an instruction to add the menu code is transmitted to the POS server 8 (S26).

On the other hand, when a deletion instruction of the menu code is received from the image recognition server 7 (S20: deletion instruction), the deletion confirmation screen 57b (see FIG. 3) is displayed on the LCD57 (S27). After the process of S27, it is confirmed which of the above-described OK button 57c or cancel button 57d is operated (S28). When cancel button 57d is operated (S28: cancel), it is assumed that tag 4 actually removed from attachment plate 11 by the customer does not match the analysis result of tag 4 in image recognition server 7, and a cancel instruction is transmitted to image recognition server 7 (S23). On the other hand, when the OK button 57c is operated (S28: OK), an OK instruction is transmitted to the image recognition server 7 (S29).

After the process of S29, the menu code for which the deletion instruction has been received from the image recognition server 7 is deleted from the subscription table 52a (S30). Then, in order to reflect the deletion of the menu code in the processing of S30 in the settlement management table 81c of the POS server 8, an instruction to delete the menu code is transmitted to the POS server 8 (S31).

By directly (without passing through the image recognition server 7) performing the deletion instruction of S31 or the addition instruction of S26 from the mobile terminal 5 to the POS server 8, the addition/deletion of the menu code in the purchase table 52a can be promptly reflected in the settlement management table 81c of the POS server 8.

If there is no instruction (or other) to add or delete the menu code from the image recognition server 7 (S20: other/none), and after the processing of S23, S26, S31, it is confirmed whether or not an order (placement) for the dish F, beverage, or the like is input by the operation of the portable terminal 5 (S32). When an order is input by the operation of portable terminal 5 (yes in S32), if the input order is a beverage, the menu code of the order is added to order table 52a (S33). On the other hand, in the case where the input order is provided together with the tag 4, the menu code is not added.

Then, in order to reflect the addition of the menu code in the processing of S33 in the settlement management table 81c of the POS server 8, an instruction to add the menu code is transmitted to the POS server 8 (S34), and the ordering processing is ended (S7). In addition, in the case where the subscription is not input by the operation in the portable terminal 5 in the process of S32 (S32: no), the subscription process is also ended (S7).

The explanation will be made with reference to fig. 7. After the process of the order process (S7), in the terminal main process, it is confirmed whether or not an instruction for the order history display is input, that is, whether or not the order history button 57g (refer to (b) of fig. 4) is operated (S8). When the instruction for the order history display is input (yes in S8), the product names and the number thereof are acquired from the purchase table 52a, the order history screen 57j (see fig. 4 (b)) is displayed together with the total amount (S9), and the process of S1 is repeated again.

On the other hand, if the instruction to display the receipt history is not input (no in S8), it is checked whether or not the settlement instruction, that is, whether or not the checkout button 57h is operated (see fig. 4 (c)) (S10). When the settlement instruction is input (yes in S10), the settlement information acquisition instruction is transmitted to the POS server 8 (S11), and the process of S1 is repeated again. The processing of S11 is processing for issuing the barcode 57l (see fig. 4 (c)).

On the other hand, if the settlement instruction is not input (S10: NO), it is checked whether or not the barcode 57l is received from the POS server 8 (S12). When the barcode is received (S12: yes), the settlement screen 57k is displayed together with the received barcode 57l (see (c) of fig. 4) (S13), and the process of S1 is repeated again.

On the other hand, when the barcode 57l is not received from the POS server 8 (S12: NO), it is checked whether or not a settlement completion notification is received from the POS server 8 (S14). When the settlement completion notification is received (yes in S14), the customer leaves the store because the settlement is completed, and the order reception is terminated (S15), and the process of S1 is repeated again.

Next, with reference to fig. 9, an image recognition process performed by the CPU70 of the image recognition server 7 will be described. Fig. 9 is a flowchart of the image recognition processing. The image recognition processing is processing executed when the power of the image recognition server 7 is turned on.

As shown in fig. 9, in the image recognition process, it is first confirmed whether or not an initialization instruction is received from the mobile terminal 5 (S40), and when the initialization instruction is received (S40: yes), the read result table 72a corresponding to the terminal ID of the mobile terminal 5 that has performed the initialization instruction is initialized (S41). On the other hand, when the initialization instruction is not received from the mobile terminal 5 (S40: no) and after the processing of S41, it is confirmed whether or not the image is received from the mobile terminal 5 (S42), and when the image is not received (S42: no), the processing of S40 is repeated again.

On the other hand, when an image is received from the portable terminal 5 (S42: YES), the terminal ID of the portable terminal 5 which has transmitted the image is acquired (S43), and stored (rewritten) in the terminal ID memory 72 b. Note that, in the following processing, the notification or instruction transmitted from the image recognition server 7 is performed in the mobile terminal 5 in which the terminal ID is stored in the terminal ID memory 72 b.

After the processing at S43, the received image is analyzed (image recognition) (S44), and it is confirmed whether or not a foreign substance other than the attachment plate 11 and the label 4 is present in the image (S45). The foreign matter is, for example, an object (a hand of a customer, chopsticks, or the like) that blocks the image of the tag 4, or dirt adhering to the tag 4.

If a foreign object other than the adhesive sheet 11 and the label 4 is present in the image (yes in S45), the process of S40 is repeated again. When the state in which the foreign object is present continues for a predetermined time, the portable terminal 5 is notified that a recognition error has occurred.

On the other hand, when there is no foreign matter other than the adhesive sheet 11 and the label 4 in the image (no in S45), the sheet number and the label 4 of the adhesive sheet 11 are extracted from the image (S46). In this way, by not performing image recognition when foreign matter other than the adhesive sheet 11 and the label 4 is present in the image, it is possible to suppress an error in recognizing the menu code from the sheet number of the adhesive sheet 11 and the label 4 due to the foreign matter. This can improve the accuracy of image recognition.

After the processing at S46, it is determined whether or not the number of labels 4 in the sticker sheet 11 of the extracted sheet number has increased or decreased with reference to the reading result table 72a (S47). In the case where the number of tags 4 is not changed (S47: no change), the process of S40 is repeated again.

On the other hand, when the number of tags 4 increases (S47: increase), the menu code corresponding to the tag 4 is acquired from the character string of the increased tag 4 with reference to menu code table 71b (S48). The character string in the label 4 is simple and stable in shape compared to the pattern. By performing image recognition on the character string, the menu code can be acquired accurately and quickly. Then, an instruction to add the obtained menu code is transmitted to the mobile terminal 5 (S49). The addition instruction is an instruction to add the menu code to the order table 52 a.

After the process of S49, standby is performed until an instruction is received from the portable terminal 5 (S50), and in the case of receiving an OK instruction from the portable terminal 5 (S50: OK), the menu code obtained in S48 is added to the read result table 72a (S51). The menu code is added to the table corresponding to the board number extracted in S46 in the read result table 72 a.

After the process of S51, it is confirmed whether the patterns of the tags 4 are aligned in a column (S52). In the case where the patterns of the tags 4 are not aligned in one column (S52: NO), the process of S40 is repeated again. On the other hand, if the patterns of the tab 4 are aligned in a row (S52: YES), an instruction to add the menu code of the discount coupon is transmitted to the portable terminal 5 (S53). This causes a discount in the subsequent settlement processing.

On the other hand, in the case where the number of tags 4 is decreased in the process of S47 (S47: decrease), the menu codes of tags 4 decreased from the reading result table 72a are acquired (S54). Then, a deletion instruction of the obtained menu code is transmitted to the portable terminal 5 (S55). The delete instruction is an instruction to delete the menu code from the order table 52 a.

After the process of S55, a standby is performed until an instruction is received from the portable terminal 5 (S56), and in the case where an OK instruction is received from the portable terminal 5 (S56: OK), the menu code obtained in S54 is deleted from the reading result table 72a (S57). The menu code is deleted in the table corresponding to the board number extracted in S46 in the read result table 72 a.

In the case where a cancel instruction is received from the portable terminal 5 in the processing of S50 and S56 (S50: cancel, S56: cancel), and after the processing of S57, the processing of S40 is repeated again.

In this way, by performing image recognition of the image captured by the mobile terminal 5, increase/decrease of the tags 4 based on the recognition, and determination of the attached state by the image recognition server 7, the processing load on the mobile terminal 5 can be reduced as compared with the case of performing the recognition and determination by the mobile terminal 5. Accordingly, the processing speed in the portable terminal 5 can be increased accordingly.

Next, the POS main process executed by the CPU80 of the POS server 8 will be described with reference to fig. 10. Fig. 10 is a flowchart of the POS main process. The POS main process is a process executed when the power of the POS server 8 is turned on.

As shown in fig. 10, in the POS main processing, it is first confirmed whether or not an instruction is received from the portable terminal 5 (S60). The instruction is an initialization instruction, an instruction to add/delete a menu code, or a settlement information acquisition instruction.

When any instruction is received from the portable terminal 5 (yes in S60), the terminal ID of the portable terminal 5 that has transmitted the instruction is acquired (S61), and stored (rewritten) in the terminal ID memory 82 a. After the process of S61, it is confirmed whether or not an initialization instruction is received (S62), and if an initialization instruction is received (S62: YES), the settlement management table 81c is initialized (S63).

On the other hand, if the initialization instruction is not received (NO in S62), it is checked whether an additional instruction for a menu code is received (S64). When an instruction to add a menu code is received (yes in S64), the instructed menu code is added to the settlement management table 81c (S65).

On the other hand, when the instruction to add the menu code is not received (NO in S64), it is checked whether or not the instruction to delete the menu code is received (S66). When the instruction for deletion is received (S66: YES), the instructed menu code is deleted from the settlement management table 81c (S67).

In this way, by adding or deleting the menu code in the settlement management table 81c, the type and number of dishes F to be eaten can be stored in the POS server 8. Therefore, it is possible to confirm the actual result of what kind of dish F is sold by the POS server 8, and therefore, it is possible to easily grasp the trend of the dish F to be eaten, and to easily perform sales management such as stock management of the dish F.

The initialization of the settlement management table 81c and the addition/deletion of the menu code in S63, S65, and S67 are performed in a table corresponding to the terminal ID stored in the terminal ID memory 82 a.

On the other hand, when the instruction to delete the menu code is not received (S66: NO), it is checked whether or not the settlement information acquisition instruction is received (S68). When the settlement information acquisition instruction is received (yes in S68), the barcode 57l is created with reference to the settlement management table 81c and transmitted to the mobile terminal 5 (S69). The barcode 57l is also created and transmitted in the mobile terminal 5 in which the terminal ID is stored in the terminal ID memory 82 a.

On the other hand, when the settlement information acquisition instruction is not received (no in S68) or when no instruction is received in the process of S60 (no in S60), it is checked whether or not the settlement process of any of the mobile terminals 5 is performed with reference to the process result in the settlement device 86 (see fig. 5) (S70). When the settlement processing is performed, a settlement completion notification is transmitted to the mobile terminal 5 that has performed the settlement processing (S71).

On the other hand, when the settlement processing is not performed in any of the mobile terminals 5 (no in S70), and after the processing in S63, S65, S67, S69, S71, the processing in S60 is repeated again. In this way, by performing settlement management in the POS server 8, inventory management of the products can be performed based on the actual results of the settlement.

As described above, according to the settlement system 100 of the present embodiment, since the CPU70 of the image recognition server 7 and the CPU80 of the POS server 8 perform the analysis and settlement processing of the image of the tag 4, the business load of the clerk can be reduced. Further, since the image recognition can be performed in a state where the tag 4 is separated from the dish 3 (dish F), the dish 3 eaten by the customer can be removed from the customer seat 1 before the settlement by the POS server 8 (settlement device 86).

The present invention has been described above based on the above embodiments, but the present invention is not limited to the above embodiments at all, and it can be easily estimated that various modifications and variations can be made within the scope not departing from the gist of the present invention.

In the above embodiment, as the restaurant to which the settlement system 100 is applied, a hot pot restaurant that provides the dish F such as meat is exemplified, but the present invention is not limited to this. The settlement system 100 of the above embodiment can be applied to any store having a floor for providing food and drink to customers.

In the above embodiment, the case where the image recognition of the tag 4 is performed by the image recognition server 7 and the coupon (discount coupon) is given based on the recognition result has been described, but the present invention is not limited to this. For example, image recognition of the tag 4 and giving of a discount (discount coupon) based on the recognition result may be performed by the mobile terminal 5 and the POS server 8. That is, the mobile terminal 5 may have the function of the image recognition server 7, or the POS server 8 may have the function of the image recognition server 7.

That is, in the above embodiment, the case where the settlement system 100 is configured by three units, i.e., the mobile terminal 5, the image recognition server 7, and the POS server 8, has been described. On the other hand, the settlement system 100 may be configured by two units by assigning the respective configurations (respective processes performed by the three units) of the three units to two units.

In the above-described embodiment, as an example of the predetermined condition for giving a preference to a customer, a case where a preference is given when the same type of (same information-containing) labels 4 are attached to the attachment plate 11 in a state aligned in a row has been described, but the present invention is not limited to this. For example, as another example of the predetermined condition, the following may be configured: advantages are given when the number of labels 4 attached to the attachment plate 11 reaches a predetermined number (for example, nine labels at the upper limit) regardless of the type, when the number of the same type of labels 4 attached to one or more attachment plates 11 reaches a predetermined number (for example, three labels), or when all the labels 4 attached to one attachment plate 11 at the upper limit number are of different types.

In the above-described embodiment, a discount coupon (discount service) in which a fee is discounted at the time of settlement has been described as an example of the advantage given to the customer, but the present invention is not limited to this. For example, the offer given to the customer may be a discount coupon available next time the customer comes to the store, or may be other services such as dish F and a small gift.

In the above embodiment, the case where the label 4 is provided to the customer together with the dish 3 and the dish F (conveyed in the conveyance path 2) has been described, but the method of providing the label 4 is not necessarily limited to the manner of placing the label on the dish 3 or inserting the dish F. For example, it may be the way that the clerk sends the dish F and the label 4 to the customer seat 1.

In the above embodiment, the case where the label 4 is not provided when ordering a part of the products (beverages) has been described, but the present invention is not limited to this. For example, the label 4 may be provided when ordering all the products, and in this case, when there is a product sent to the seat by a store clerk, the store clerk may send the product to the seat together with the label 4.

In the above embodiment, the case where the pasting regions 11a of 3 rows × 3 columns (multiple rows × multiple columns) are formed in the pasting board 11 (the pasting regions 11a are regularly formed) has been described, but the present invention is not limited to this. For example, the plurality of attachment areas 11a may be irregularly distributed on the attachment plate 11, or the attachment areas 11a may be omitted.

In the above embodiment, the case where the label 4 is aligned by forming the adhesive region 11a (frame line) on the adhesive sheet 11 has been described, but the present invention is not limited to this. For example, the following may be configured: the adhesive sheet 11 is provided with a recess (projection) surrounding a part or all of the outline of the label 4, and the label 4 is fitted into the recess (projection) to align the orientations (restrict rotation).

In addition, the case where the corner portion 4a (corner portion 11b) is provided in the label 4 (adhesive sheet 11) as a shape that facilitates alignment of the label 4 has been described, but the present invention is not limited to this. For example, the shape of the label 4 in a plan view may be circular, but the shape of the label 4 in a plan view is preferably non-circular, such as a polygon or a combination of a straight line and a curved line, and more preferably a shape having no rotational symmetry. That is, it is preferable to have a configuration in which the orientation of the label 4 can be specified when the label is attached along the attachment region 11a, and for example, even if the shape of the label 4 in a plan view is a regular polygon, the adjustment in the vertical direction can be easily performed as compared with the case of a circle. However, if the label 4 is a regular polygon having rotational symmetry, the label 4 (the pasting region 11a) may not be pasted in the correct orientation. Therefore, by forming the labels 4 (the pasting region 11a) in a shape without rotational symmetry as in the above-described embodiment, it is possible to reliably align the labels 4 pasted on the pasting region 11a in the correct direction.

In the above embodiment, the case where the tag 4 is in the form of a plate has been described, but the present invention is not limited to this. For example, the label 4 may be a polyhedron such as a rectangular parallelepiped or a cube, or a sphere. Regardless of the shape of the label 4, the label 4 may be attached to the attachment plate 11 by providing a recess or a protrusion capable of holding the label 4 (corresponding to the outer shape of the label 4) or by using a magnet as in the above-described embodiment.

In the above embodiment, the case where the placing table 12 is provided in the customer seat 1 has been described, but the present invention is not limited to this. For example, the placement table 12 may be omitted, and the customer may read the information of the tag 4 while holding the mobile terminal 5.

In the above-described embodiment, the case where the information of the tag 4 (the content of the dish F) is identified by performing image recognition on the character string of the tag 4 has been described, but the present invention is not limited to this. For example, the information of the label 4 may be identified by a pattern, a color, an amount, or a menu code (a code assigned to the content or the amount of the dish F) displayed on the label 4.

Further, the label 4 may be configured to display a plurality of characters, patterns, colors, amounts, or menu codes, either one or both of which are displayed.
