Description

  The present invention relates to a technique for promoting customer sales and promoting sales in an electronic cash register. More specifically, the present invention relates to a technique for performing a discount calculation for a specific product among products purchased by a customer.

  When a customer purchases multiple products at a supermarket, bring them to a cashier counter at the same time for payment. At this time, an electronic cash register is used that calculates the amount charged to the customer based on the selling price of each purchased product. The electronic cash register acquires the selling price of each purchased product, calculates the billed amount by adding the selling price, and outputs the billed amount to an output device such as a display or a printing device.

  On the other hand, the electronic cash register is a device used at the point of contact between the store side and the customer, and conventionally, an electronic cash register useful for sales promotion has been proposed. For example, Patent Document 1 discloses an electronic cash register that promotes customer purchasing motivation.

  The electronic cash register described in Patent Document 1 prints a coupon on a receipt by using a function of a printing apparatus that outputs a billed amount as a receipt. Since the receipt is given to the customer after printing, a coupon is issued to the customer who has purchased the product, and the next visit is encouraged.

  A method for promoting sales has also been proposed in an apparatus for printing a label attached to a product. Such a technique is described in Patent Document 2, for example.

  The technology described in Patent Document 2 prints information on discounts on tie-up products on a label as a coupon, and gives a target product (for example, “meat for roast meat”) to a customer who purchases a specific product ( For example, it is a technology that further encourages the purchase of “baked meat sauce”). Such a sales promotion method is appealing to a specific customer, and is particularly effective in increasing the willingness to purchase.

Japanese Utility Model Publication No. 06-074362 Japanese Patent Laid-Open No. 06-091950

  However, the technique described in Patent Document 1 has a problem that the content to be printed is uniform for all customers.

  Further, in the technique described in Patent Document 2, it is necessary to find the “meat for grilled meat” from a plurality of purchased products brought to the checkout counter and then perform a discount on “sauce for grilled meat”. In other words, not only the products whose sales price has already been read must be checked again to see if they contain “baked meat sauce”, but the products to be processed do not contain “baked meat sauce”. It must be handled with care. That is, there is a problem that the burden on the operator who operates the electronic cash register increases.

  In addition, in the technique described in Patent Document 2, a customer who has purchased “meat for roasted meat” but has not purchased “sauce for roasted meat” has to bother to remove the coupon printed on the label from the product next time. There was a problem that the sales promotion effect declined.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an electronic cash register that can reduce the burden on an operator and can effectively promote sales.

In order to solve the above-mentioned problem, the invention of claim 1 is an electronic cash register that outputs an amount charged to the customer based on an individual selling price of at least one purchased product purchased by the customer, A determination unit that reads coupon information attached to one purchased product and determines a target product to be discounted and a discount amount of the target product based on the read coupon information ; A determination unit that determines whether or not the determined target product is included in the at least one purchased product, and the determination unit determines that the target product is included in the at least one purchased product. when was the, and calculating means for calculating the amount billed while discount the selling price of the subject merchandise based on the discounted value of the subject merchandise, in the judgment means If the target commodity is determined not included in said at least one purchasing goods, and printing means for printing the coupon information according to the discount amount of the Shipping and Shipping to be the discount It is characterized by providing.

The invention of claim 2 is the electronic cash register according to the invention of claim 1 , wherein the printing means prints a discount amount different from the discount amount of the target product as the coupon information. To do.

The invention of claim 3 is the electronic cash register according to the invention of claim 1 or 2 , wherein the printing means prints an expiration date as the coupon information.

In the inventions according to claims 1 to 3, when it is determined that the target product is included in at least one purchased product, the amount charged while discounting the selling price of the target product based on the discount amount of the target product By calculating, it is not necessary for the operator to check whether or not the purchased product contains the target product, so that the payment work time at the cash register can be shortened and the burden on the operator can be reduced. Further, the service for the customer can be surely executed by preventing the operator from overlooking it.

Furthermore, in the inventions according to claims 1 to 3 , if the determination means determines that the target product is not included in at least one purchased product, the target product to be discounted and the discount amount of the target product The discount service can be carried over to the next time by printing coupon information according to the above. Further, even when a coupon is attached to the product, the customer does not have to remove the coupon from the product and bring it.

In the invention according to claim 2 , by printing a discount amount different from the discount amount of the target product as coupon information, for example, to increase the discount amount when used at a later date in order to have the customer visit again, It is possible to differentiate between a customer who uses the day and a customer who uses the day later.

In the invention described in claim 3 , it is possible to strongly appeal another visit by printing the expiration date as coupon information.

  The keyboard 22 has a structure in which a plurality of buttons are arranged, and is used when an operator inputs an instruction or data to the terminal 2. The keyboard 22 converts the input received from the operator into an electrical signal and transmits it to the control unit 10.

  The terminal 2 includes a magnetic card reader 23 and a receipt printer 24.

  The magnetic card reader 23 is an input device for reading information stored in a magnetic card (not shown). Thereby, the electronic cash register 1 can read information such as a customer's point card, for example.

  The receipt printer 24 is a device that prints and outputs data on receipt paper. Although not shown in detail, the terminal 2 can set a roll paper as a receipt paper inside.

  The scanner 3 is a handy type general bar code reader, and mainly reads a bar code of a label attached to a purchased product and transmits it to the terminal 2.

  FIG. 3 is a diagram illustrating an example of a label 100 attached to a product. In the present embodiment, the product identification information 101 and the coupon identification information 102 are barcodes and are printed on a label 100 attached to the product. That is, a coupon for a tie-up product (xxx grilled meat sauce) with the product (roasted meat) shown in the product identification information 101 is printed on the same label 100 as the coupon identification information 102.

  The scanner 3 has a function of reading the product identification information 101 and the coupon identification information 102 regarding each product, and mainly corresponds to the input unit and the reading unit in the present invention. However, these pieces of information may be input from the keyboard 22.

  FIG. 4 is a block diagram showing a functional configuration realized by the CPU 11 operating according to a program together with a data flow. The product determination unit 110, the coupon determination unit 111, and the calculation unit 112 illustrated in FIG. 4 are functional configurations realized by the CPU 11.

  Here, the product master table 130 and the coupon master table 131 are databases created in advance and stored in the hard disk 13.

  FIG. 5 is a diagram illustrating an example of the product master table 130. The product master table 130 is constructed as a database that can be searched using the product identification information 101 (product code) as a keyword, and is capable of acquiring various unique information (product information) for each product. . In FIG. 5, “product name” and “amount (sale price)” are shown as examples of the product information, but of course, the present invention is not limited to this. In FIG. 5, the “money amount” of “roasted meat roast” and “roasted meat ribs” is not stored in the product master table 130, but these products are products priced according to the weighing weight, for example, The bar code which is the product identification information 101 includes information related to “amount”.

  FIG. 6 is a diagram illustrating an example of the coupon master table 131. The coupon master table 131 is constructed as a database that can be searched using the coupon identification information 102 (identification code) as a keyword, and can acquire various unique information (coupon information) for each coupon. . In FIG. 6, “coupon name”, “target product (product code of the target product)”, “expiration date”, and “next discount amount” are shown as examples of the coupon information. Absent.

  The product determination unit 110 searches the product master table 130 of the hard disk 13 on the basis of the product identification information 101 read by the scanner 3 and acquires the amount (product information) of the purchased product. Moreover, it is determined with reference to the coupon check table 103 whether the coupon which makes the said purchased goods the object goods exists. In accordance with the determination result, the coupon check table 103 is updated and the purchased product is registered in the product specification table 104.

  The coupon determination unit 111 searches the coupon master table 131 of the hard disk 13 based on the coupon identification information 102 read by the scanner 3 and acquires coupon information. Then, using the “target product (product code)” included in the coupon information as a keyword, the product description table 104 is searched to determine whether the coupon target product is registered. In accordance with the determination result, the coupon determination unit 111 updates the coupon check table 103 and the product description table 104.

  The calculation unit 112 generates display information 105 based on the updated product detail table 104 every time the product detail table 104 is updated. Further, when there is a settlement instruction from the keyboard 22, the coupon check table 103 is referred to determine whether there is an unused coupon, and print information 106 is generated according to the result. Although details are omitted, the display information 105 is created for each operator display 20 and customer display 21.

  The above is the description of the configuration and function of the electronic cash register 1 in the present embodiment. Next, the operation of the electronic cash register 1 will be described.

  7 and 8 are flowcharts showing the operation of the electronic cash register 1 in the first embodiment.

  In the electronic cash register 1 in the present embodiment, initial setting is first executed when starting a transaction (step S11). In the initial setting, processing such as initialization of the coupon check table 103 and the product description table 104 is performed.

  Next, the scanner 3 reads the barcode of the purchased product (product brought by the customer) (step S12). Only the product identification information 101 is printed on a label attached to a normal product, but coupon identification information 102 is also printed on the tie-up product as shown in FIG.

  The control unit 10 determines whether or not the barcode read by the scanner 3 is the product identification information 101 (step S13). If the barcode is the product identification information 101, the product registration process (step S14) is executed. If it is not the product identification information 101, a coupon registration process (step S15) is executed.

  First, the product registration process in step S14 will be described.

  FIG. 9 is a flowchart showing a product registration process according to the first embodiment. In the product identification process, the product determination unit 110 refers to the product master table 130 using the product identification information 101 acquired by the scanner 3 as a keyword (step S31). And based on the merchandise information (amount) acquired from the merchandise master table 130, the merchandise details table 104 is created (step S32).

  FIG. 10 is a diagram illustrating an example of the product detail table 104. For example, when the product identification information 101 of “Yakiniku roast” is first read, an information table related to the purchased product is created as the first record as shown in FIG. That is, the purchased product is registered in the product description table 104.

  In addition, when “Yakiniku loin” is subjected to product registration processing, since “Yakiniku loin” is a metered product (with different contents), “sales price (1280 yen)” is determined from the information included in the product identification information 101. Is remembered. On the other hand, when “XXX grilled meat sauce” is registered as a product, “amount (298)” stored in the product master table 130 is stored as “selling price (298)” in the product specification table 104. .

  Next, the product determination unit 110 refers to the coupon check table 103 using the product identification information 101 as a keyword (step S33).

  FIG. 11 is a diagram illustrating an example of the coupon check table 103. Although the creation method of the coupon check table 103 will be described later, the coupon check table 103 stores information on available coupons.

  The product determination unit 110 determines whether or not a coupon related to the purchased product is registered in the coupon check table 103 (step S34). This determination is performed by searching for “target product” in the coupon check table 103 using the product identification information 101.

  In the example shown in FIG. 11, no coupon for “Yakiniku roast” is registered. Therefore, when the product registration process for “roasted meat roast” is performed, the product determination unit 110 determines No in step S34 and skips steps S35 and S36.

  When the update of the product detail table 104 is completed, the calculation unit 112 creates display information 105 and displays it on the operator display 20 and the customer display 21 (step S37).

  FIG. 12 is a diagram illustrating an example of a screen displayed on the customer display 21. The “sales price (1280 yen)” is displayed along with the “product name (roasted meat)” of the purchased product. As a result, the customer can confirm the product purchased by the customer and its price. However, no discount is applied to “roasted meat”.

  On the other hand, in the example shown in FIG. 11, a coupon having “xxx grilled meat sauce” as a target product is registered. Accordingly, when the product registration process is performed on “xxx grilled meat sauce”, the product determination unit 110 determines Yes in step S34. And the information (the lower 2nd digit-the 5th digit) regarding the “discount amount” included in the coupon identification information 102 of the coupon check table 103 is acquired and stored in the “discount amount” of the product description table 104 created in step S32. . Thereby, the product details table 104 is updated (step S35).

  At this time, if the processing flag is checked and the coupon has been used, the product detail table 104 may not be updated. The processing flag is a flag for determining whether or not the coupon is used, and “0” indicates unused and “1” indicates used.

  When the update of the product detail table 104 is completed, the product determination unit 110 updates the processing flag of the coupon check table 103 to “1” (step S36). This makes it possible to determine that the coupon has been used in later processing.

  When the update of the product detail table 104 and the coupon check table 103 is completed, the calculation unit 112 creates display information 105 and displays it on the operator display 20 and the customer display 21 (step S37).

  FIG. 13 is a diagram illustrating an example of a screen displayed on the customer display 21. Even when the discount is applied, the “sales price (298 yen)” is displayed together with the “commodity name (xxx grilled meat sauce)” of the purchased product. Further, the fact that the coupon has been discounted and the “discount amount (−50 yen)” are displayed. Accordingly, the customer can confirm that the discount service has been received for the tie-up product (purchased product).

  If step S37 is performed, the control part 10 will complete | finish a goods registration process, and will return to the process of FIG.

  Returning to FIG. 7, when the product registration process (step S14) is completed, the control unit 10 determines whether or not the payment is to be made (step S16), and when the payment is instructed by the operator, the process of step S21 is executed. To do. On the other hand, if there is another purchased product (or coupon), the process returns to step S12.

  Next, the case where the coupon registration process of step S15 is executed (No in step S13) will be described. That is, a case where the coupon identification information 102 is read by the scanner 3 will be described.

  FIG. 14 is a flowchart showing the coupon registration process in the first embodiment. In the coupon registration process of step S15, the coupon determination unit 111 refers to the coupon master table 131 using the coupon identification information 102 acquired by the scanner 3 as a keyword (step S41).

  The coupon determination part 111 acquires the coupon information of the coupon applicable to the coupon identification information 102 from the coupon master table 131, and creates the coupon check table 103 as shown in FIG. 11 (step S42). Thereby, the coupon corresponding to the coupon identification information 102 is registered in the coupon check table 103. At this time, the coupon determination unit 111 sets the processing flag to “0”.

  When the registration of the coupon is completed, the coupon determination unit 111 refers to the product specification table 104 (step S43), and searches for “target product” included in the coupon information of the coupon as a keyword, thereby changing the “target product”. It is determined whether or not a matching product is registered as a purchased product in the product description table 104 (step S44).

  In the example illustrated in FIG. 10, when the coupon registration process is performed for the “xxx grilled meat sauce” coupon, the purchased product (xxx grilled meat sauce) matching the target product of the coupon is registered in the product specification table 104. ing. In this case, the coupon determination unit 111 sets the processing flag for the coupon in the coupon check table 103 to “1” (step S45). In addition, the coupon determination unit 111 selects “xxx barbecue sauce” in the product specification table 104 based on information related to “discount” included in the coupon identification information 102 (a numerical value indicated by a predetermined digit of the barcode). The “discount” is updated (step S46).

  When the update of the product detail table 104 is completed, the calculation unit 112 creates display information 105 based on the coupon check table 103 and displays it on the operator display 20 and the customer display 21. (Step S47).

  FIG. 15 is a diagram illustrating an example of a screen displayed on the customer display 21. As shown in FIG. 15, if “target product” exists, “coupon name (xxx coupon for grilled meat)”, service content display (coupon discount), “discount” Is displayed. Thus, the customer can confirm that the discount for the tie-up product has been executed.

  On the other hand, in the example shown in FIG. 10, when the “△△△ grilled meat sauce” coupon is registered in the coupon, the purchased product (△△△ grilled meat sauce) matching the target product of the coupon is displayed in the product specification table 104. not registered. Therefore, the coupon determination part 111 determines No in step S44 and skips the processes of steps S45 and S46. Then, the calculation unit 112 creates display information 105 based on the coupon check table 103 and displays it on the operator display 20 and the customer display 21. (Step S47).

  FIG. 16 is a diagram illustrating an example of a screen displayed on the customer display 21. As shown in FIG. 16, in the coupon registration process, when there is no “target product”, only “coupon name (ΔΔΔ roasted meat coupon)” is displayed. Thereby, the customer can confirm that the coupon is registered in a usable state.

  If step S47 is performed, the control part 10 will complete | finish a goods registration process, and will return to the process of FIG.

  Returning to FIG. 7, when the coupon registration process (step S15) ends, the control unit 10 determines whether or not to settle (step S16), similarly to the case where the product registration process (step S14) ends. At this time, when settlement is instructed by the operator, the process of step S21 is executed. On the other hand, if there is another purchased product (or coupon), the process returns to step S12.

  When settlement is instructed by the operator, it is determined as Yes in step S16, and as shown in FIG. 8, the calculation unit 112 generates print information 106 based on the product specification table 104 created so far ( Step S21). At this time, the calculation unit 112 calculates the “billing amount (total amount)” by subtracting the “discount amount” while totaling the “selling prices” shown in the product detail table 104.

  Further, the computing unit 112 refers to the coupon check table 103 and determines whether or not there is a coupon whose processing flag is “0” (step S22).

  If there is an unprocessed coupon, the coupon information of the coupon is added to the print information 106 (step S23). At this time, the calculation unit 112 includes, as the “discount amount”, not the information related to the “discount amount” indicated in the coupon identification information 102 but the value indicated in the “next discount amount” in the print information 106.

  Thereby, the electronic cash register 1 in this Embodiment can differentiate the customer who uses a coupon that day, and the customer who uses a coupon later. That is, a flexible service can be provided.

  In addition, the calculation unit 112 includes the “expiration date” of the coupon in the print information 106. As a result, the customer can be invited to visit the store again by the expiration date, so that a more flexible service can be provided.

  In step S23, the calculation unit 112 sets the processing flag of the coupon added to the print information 106 to “2”. Thereby, in the subsequent process, the used coupon (processing flag is “1”) and the reissued coupon (processing flag is “2”) can be distinguished.

  Thereby, for example, if the coupon check table 103 is preserve | saved about each transaction, the usage rate etc. of the coupon in a tie-up goods can be calculated, and it can utilize for further sales promotion. In order to realize such processing, if a coupon is added to the print information 106, a processing flag is included in information related to the coupon in the print information 106 (coupon information 102 printed on a receipt described later). Good.

  When the coupon with the processing flag “0” no longer exists, the calculation unit 112 ends step S23, causes the receipt printer 24 to print the print information 106 (step S24), and ends the process.

  FIG. 17 is a diagram illustrating an example of a receipt 107 on which print information 106 is printed in the examples illustrated in FIGS. 10 and 11. As shown in FIG. 17, “total (billed amount)” calculated by the calculation unit 112 is printed on the receipt 107. Further, a “ΔΔΔ grilled meat sauce” coupon that has not been used is printed as new coupon identification information 102, and its expiration date display 108 is also printed. The discount amount display 109 for the next use is displayed as 90 yen, which is a discount amount different from the discount amount (100 yen) of the coupon information. Note that the next discount amount may be higher than the discount amount used this time. That is, the electronic cash register 1 can flexibly cope with a sales promotion strategy for each store.

  As described above, in the electronic cash register 1 according to the present embodiment, the operator does not need to be aware of whether or not the target product of the coupon is included in the purchased product, so that the burden on the operator can be reduced. Moreover, since customer satisfaction can be improved by preventing a discount mistake, effective sales promotion can be performed.

  In particular, it is not necessary to look for two products that have been put into shopping carts separately when recommending purchase of tie-up products to customers who have purchased a specific product. Can be reduced.

  In addition, when a coupon is attached to the purchased product, the coupon identification information 102 is displayed together with the product identification information 101 to ensure that the product identification information 101 and the coupon identification information 102 are read regardless of the reading order. Discount services can be performed. That is, the coupon may be read at any timing until payment is instructed, and the burden on the operator is reduced.

  In addition, by automatically printing a coupon that has not been used on a receipt, it is possible to encourage the next visit and to promote more effective sales promotion.

  In addition, as shown in FIG. 3, even when the coupon identification information 102 is attached to the product in a state of being printed on the label 100, the customer does not need to remove the label 100 and bring it in. Convenience is improved.

  In the present embodiment, as shown in FIG. 3, the example in which the coupon (coupon identification information 102) is attached to the product as a barcode has been described. However, the present invention is not limited to this. The same processing can be performed even if the received receipt 107 is read by the scanner 3. A coupon that is printed on a leaflet and distributed separately can also be used.

<2. Second Embodiment>
In the first embodiment, the example in which the coupon identification information 102 is attached to a product (printed as a barcode on a label) has been described. However, in order to realize a service such as discounting other tie-up products for a customer who has purchased a specific product, it is not necessary to use a coupon as a medium.

  FIG. 18 is a diagram illustrating an example of the product master table 130a according to the second embodiment configured based on such a principle. In addition, about the electronic cash register 1 in 2nd Embodiment, description is abbreviate | omitted below about the function, a structure, and operation | movement similar to the electronic cash register 1 in 1st Embodiment.

  The product master table 130a is different from the product master table 130 in the first embodiment in that an item “coupon identification information” is provided. The information stored in the “coupon identification information” is information corresponding to the coupon identification information 102 in the first embodiment.

  The product determination unit 110 in the second embodiment acquires information stored in the “coupon identification information” as the coupon identification information 102 when searching the product master table 130a using the product identification information 101 as a keyword. And transmitted to the coupon determination unit 111.

  The coupon determination unit 111 performs the same processing as when the coupon identification information 102 is read by the scanner 3 even when the coupon identification information 102 is received from the product determination unit 110.

  As a result, the electronic cash register 1 in the second embodiment has the same effects as those in the first embodiment even when the label 100 as shown in FIG. 3 is not attached to the purchased product in advance. Can be obtained. That is, it is possible to provide a desired service quickly only by rewriting the product master table 130a without performing work such as label replacement for each product. Therefore, it is particularly effective when combined with a time service or the like.

  Further, since the present invention can be applied even to a label printing apparatus having no function for printing coupons, the system cost can be reduced.

  Further, it is possible to prevent a situation in which the discount is not performed due to a mistake in reading the coupon identification information 102.

  Furthermore, since the number of times of reading by the scanner 3 can be reduced, the burden on the operator can be reduced.

<3. Modification>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made.

  For example, in the first embodiment, the example in which two barcodes (the product identification information 101 and the coupon identification information 102) of the label 100 attached to the product are read separately has been described. May be used. That is, the scanner 3 may have a function of simultaneously reading two levels of barcodes.

  In addition, although the commodity determination unit 110, the coupon determination unit 111, and the calculation unit 112 of the electronic cash register 1 have been described as being realized by software by the CPU 11 operating according to a program, some or all of these functions are implemented. You may implement | achieve in hardware by a dedicated circuit.

  Further, the operation process of the electronic cash register 1 described in the above embodiment is not limited to this. For example, the order of each process may be changed as appropriate. In other words, any order in which similar effects can be obtained may be used.

  Furthermore, the information included in the product master tables 130 and 130a, the coupon master table 131, and the like is not limited to the example shown in the above embodiment, and various information may be included depending on the service. . For example, the coupon information is described as “discount amount”, but may be “discount rate”.
