Description

[Technical field]

[0001] An embodiment of the present invention relates to a product sales data processing device and a program. [Background technology]

[0002] In some retail stores such as supermarkets, bulk purchases, or combinations of specified products, are sold at a lower price than if the products were purchased individually at their normal prices (see, for example, Patent Document 1).

[0003] However, in such conventional bulk sales, the combination of products was fixed to one. Therefore, for example, it was not possible to set a different discount amount for the combination of products A and B and the combination of products A and C. Therefore, the combination of products in the bulk sale was limited, resulting in a problem of lack of flexibility in the service. Summary of the Invention [Problem to be solved by the invention]

[0004] An object of the present invention is to provide a product sales data processing device and program that can flexibly set a combination of products to be sold in a bulk sale. [Means for solving the problem]

[0005] The product sales data processing device of the embodiment includes a registration means, a selection means, a discount means, and an update means. The registration means executes a registration process for products to be sold to customers. The selection means selects a combination of products that are eligible for a bulk sale from among the registered products based on information indicating whether the products are eligible for a bulk sale. The discount means sets a discount amount according to the combination of products selected by the selection means. The update means updates the combination of products and the discount amount when the selection means selects a combination of products that offers a larger discount amount.

[0007] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a product sales data processing device according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0008] (Explanation of the overall configuration of the product sales data processing device) 1 is a perspective view showing the appearance of a POS (Point Of Sales) terminal device 10, which is an example of a product sales data processing device according to this embodiment. The POS terminal device 10 includes a keyboard 4, a cashier display operation unit 5 which is an example of a cashier display means, a receipt printer 6, a customer display unit 7 which is an example of a customer display means, and a barcode reader 8.

[0009] The keyboard 4 and the cashier-side display / operation unit 5, which are user interfaces, are disposed on the top surface of the POS terminal device 10, with the keyboard 4 on the front side and the cashier-side display / operation unit 5 on the back side.

[0010] The keyboard 4 is part of the input device and has multiple keys such as numeric keys, a clear key, a return key, a subtotal key, and a closing key. The numeric keys are a numeric keypad for inputting numerical values ​​such as product codes and amounts. The clear key is a key for canceling an operation when an error occurs. The return key is a key for canceling the current operation and returning to the previous screen. The subtotal key is a key for completing the product registration process for registering products and declaring the calculation of the total transaction amount. The closing key is a key pressed to confirm the input information and perform the payment process (accounting process).

[0011] The cashier-side display operation unit 5 includes a display device such as an LCD (Liquid Crystal Display) panel 5a, and a touch panel 5b laminated on the surface of the display device. The LCD panel 5a displays to the cashier a screen corresponding to the processing status of the registration process, the settlement process, etc. The touch panel 5b detects the screen displayed on the LCD panel 5a or the cashier's pressing of a button or the like, and controls the operation of the POS terminal device 10 according to the position pressed.

[0012] The receipt printer 6 is disposed on the top left side of the POS terminal device 10 and prints itemized slips and receipts to be handed to customers. The receipt printer 6 also has an issuing port 6a and issues printed receipts.

[0013] The customer-side display unit 7 is composed of an LCD panel (see FIG. 2), and is provided on the upper rear side of the POS terminal device 10. The customer-side display unit 7 is disposed with its display surface facing the customer, and displays the price of registered products, the discount amount, the total transaction amount, the total discount amount, etc. In the following, the customer-side display unit 7 may be referred to as the LCD panel 7.

[0014] Furthermore, a barcode reader 8 that reads code data contained in a barcode affixed to a product is connected to the POS terminal 10. The barcode reader 8 decodes a light receiving signal of the code data, acquires the code data represented by the barcode (product code that identifies the product), and outputs the code data to the CPU 22 (see FIG. 2) of the POS terminal 10.

[0015] (Description of the hardware configuration of the POS terminal) Next, the hardware configuration of the POS terminal 10 will be described with reference to FIG. 2. FIG. 2 is a hardware block diagram showing an example of the hardware configuration of the POS terminal 10. As shown in FIG. 2, the POS terminal 10 includes a control unit 20 for controlling each unit. The control unit 20 has a typical computer configuration including a CPU (Central Processing Unit) 22, a ROM (Read Only Memory) 24, and a RAM (Random Access Memory) 26. The CPU 22 loads various programs stored in the ROM 24 and the storage unit 30 into the RAM 26. The CPU 22 operates according to the various programs loaded into the RAM 26, and controls the entire POS terminal 10.

[0016] The control unit 20 is connected to the storage unit 30 and the controller 50 via a bus line 40 .

[0017] The storage unit 30 is a non-volatile memory such as a flash memory that retains stored information even when the power is turned off. The storage unit 30 stores programs including a control program P1. The control program P1 is a program for implementing the functions of the POS terminal device 10. The storage unit 30 also stores a discount master 32. The discount master 32 is a master file that stores a product code, a product name, a product price, etc. in association with each other, and stores a combination of products that are discounted when purchased in bulk and the discount amount. Since the contents of the discount master 32 are updated daily, the POS terminal device 10 periodically receives the latest contents of the discount master 32 from the store server via a communication interface not shown in FIG. 2.

[0018] The controller 50 connects the control unit 20 to various peripheral devices, namely, the LCD panel 5a, the touch panel 5b, the LCD panel 7, the keyboard 4, the barcode reader 8, and the receipt printer 6. The controller 50 controls the various peripheral devices connected thereto based on commands from the control unit 20.

[0019] (Description of the functional configuration of the POS terminal device) Next, the functional configuration of the POS terminal 10 will be described with reference to Fig. 3. Fig. 3 is a functional block diagram showing an example of the functional configuration of the POS terminal 10.

[0020] The CPU 22 (see FIG. 2) of the control unit 20 reads out the control program P1 stored in the storage unit 30 and loads it in the RAM 26. The control unit 20 operates according to the control program P1 to generate each of the functional units shown in FIG. 3 on the RAM 26. Specifically, the control unit 20 realizes, as functional units, a registration unit 20a, a selection unit 20b, a discount setting unit 20c, an update unit 20d, a display control unit 20e, and a print control unit 20f.

[0021] The registration unit 20a is an example of a registration means, and executes a registration process for the products sold to customers.

[0022] The selection unit 20b is an example of a selection means, and selects a combination of products that are eligible for bulk sales from among the registered products based on information in the discount master 32 indicating whether the products are eligible for bulk sales.

[0023] The discount setting unit 20c is an example of a discount means, and sets a discount amount according to the combination of products selected by the selection unit 20b. More specifically, the discount setting unit 20c sets a discount amount according to the combination of products selected by the selection unit 20b by referring to the discount master 32.

[0024] The update unit 20d is an example of an update means, and updates the product combination and the discount amount when the selection unit 20b selects a product combination that results in a larger discount amount.

[0025] The display control unit 20e displays information including the selected combination of products that are eligible for bulk sale on the cashier-side display operation unit 5. The display control unit 20e also displays information including the selected combination of products that are eligible for bulk sale on the customer-side display unit 7.

[0026] The print control unit 20f is an example of a printing means, and prints and issues information including the selected combination of products that are the subject of the bulk sale on a receipt.

[0027] (Explanation of discount master configuration) Next, the configuration of the discount master 32 will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of the configuration of the discount master 32.

[0028] 4, the discount master 32 stores information such as product identification information 32b, target category 32c, discount amount when the combination is established 32d, and campaign name 32e. The same ID number is assigned to the combined products belonging to the same plan as the ID number 32a of the combined plan.

[0029] The product identification information 32b further stores a product code 34a, a product name 34b, and a unit price 34c. The product code 34a is, for example, a Japanese Article Number (JAN) code, which is a unique identification number given to each product. The product name 34b is the name of each product. The unit price 34c is the unit price of each product.

[0030] The target category 32c stores information for each product as to whether it is a condition product, a discounted product, or neither. A condition product is a product that is eligible for a bulk discount. A discounted product is a product that becomes eligible for a bulk discount when purchased together with a condition product. If the product does not fall into either the condition product or the discounted product, the target category 32c is left blank.

[0031] The discount amount when a combination is established 32d indicates the discount amount when the condition product and the discount target product are purchased together.

[0032] The campaign name 32e indicates the name of a service offering a bulk discount.

[0033] (Explanation of the concept of bulk discounts) Next, the concept of a bulk discount will be described with reference to Fig. 5. Fig. 5 is a diagram showing a method of setting a discount amount when a bulk discount is applied.

[0034] For example, suppose that a condition product, lunch box A, and discounted products, drinks A and B, are purchased in bulk. In this case, referring to the contents of the discount master 32 (see FIG. 4) described above, there are two possible product combinations that can be discounted in bulk (lunch box A and drink A, and lunch box A and drink B), as shown in FIG. 5(a). In such a case, the combination of products with the larger discount amount is made to be made. That is, the combination of lunch box A and drink B is made to be made, as shown in FIG. 5(b). In this case, drink A, which is not included in the product combination, is sold without discount (150 yen).

[0035] Although not shown in FIG. 5, when the same discount target product is registered multiple times, a condition product that makes up a combination is searched for for each of the registered multiple discount target products.

[0036] (Explanation of the flow of product registration processing performed by POS terminal device) Next, the flow of processing performed by the control unit 20 of the POS terminal device 10 based on the control program P1 will be described with reference to Fig. 6. Fig. 6 is a flow chart showing an example of the flow of product registration processing for registering products purchased by a customer, among the processing performed by the POS terminal device 10.

[0037] The registration unit 20a registers one item that the customer purchases (step S10).

[0038] The selection unit 20b selects a combination of products that can be sold together from the one product registered in step S10 and products that have already been registered (step S12).

[0039] Furthermore, the discount setting unit 20c judges whether there is a product combination with a larger discount amount (step S14). If it is judged that there is a product combination with a larger discount amount (step S14: Yes), the process proceeds to step S16. On the other hand, if it is not judged that there is a product combination with a larger discount amount (step S14: No), the process proceeds to step S20.

[0040] In step S16, the update unit 20d updates the product combinations.

[0041] Next, the selection unit 20b reselects a combination of products that can be discounted in bulk for the products that were excluded from the combination in step S16 (step S18).

[0042] The display control unit 20e displays all the selection results, including the product combination selected in step S18, on the cashier-side display operation unit 5 and the customer-side display unit 7 (step S20).

[0043] The registration unit 20a judges whether the registration of all the products has been completed (step S22). Specifically, for example, the registration unit 20a detects that a closing key on the keyboard 4 has been pressed to judge whether the registration of all the products has been completed. If it is judged that the registration of all the products has been completed (step S22: Yes), the processing of FIG. 6 is terminated. On the other hand, if it is not judged that the registration of all the products has been completed (step S22: No), the processing returns to step S10 to register the next product.

[0044] Although not shown in the figure, after the product registration process shown in FIG. 6 is completed, the POS terminal device 10 performs a payment process to make a payment based on the registered product details, and a receipt printing process to print the payment details on a receipt and issue it.

[0045] (Explanation of the specific flow of product registration processing) Next, the flow of the process performed by the control unit 20 of the POS terminal device 10 based on the control program P1 will be described with reference to Fig. 7. Fig. 7 is a diagram showing a specific flow of the product registration process performed by the POS terminal device 10 when registering the product set in the discount master 32 of Fig. 4.

[0046] 7(a) to 7(d) show an example of the progress of the product registration process stored in the RAM 26 of the control unit 20 when the POS terminal device 10 performs the above-mentioned product registration process.

[0047] First, when lunch box A is registered, as shown in Fig. 7(a), the product name "lunch box A" and the price of lunch box A "800 yen" are registered in the RAM 26. Then, the POS terminal device 10 waits for the registration of the next product.

[0048] Next, when lunch box B is registered, as shown in FIG. 7(b), the product name "lunch box B" and the price of lunch box B, "1000 yen", are registered in the RAM 26. Furthermore, the total transaction amount, "1800 yen", is registered in the RAM 26. Then, the POS terminal device 10 waits for the registration of the next product.

[0049] Next, when drink A is registered, as shown in FIG. 7(c), the product name "drink A" is registered. Since "drink A" is a discounted product, the selection unit 20b selects a product that can be purchased in combination with "drink A" from among the already registered products to which a bulk discount is applied. At this time, the selection unit 20b selects products in the order of registration, so that the first registered "lunch box A" is selected. The discount setting unit 20c calculates that the discount amount for the bulk discount is "30 yen". Furthermore, the calculated discount amount "30 yen" and the fact that the price of "drink A" will be "120 yen" as a result of the discount are registered in the RAM 26. Furthermore, information indicating that "drink A" and "lunch box A" are a combination of products that are eligible for bulk sales is registered in the plan column of the RAM 26. Specifically, a, b, ... are registered in alphabetical order in the plan column. Furthermore, the total transaction amount "1920 yen" and the total discount amount "30 yen" are registered in the RAM 26.

[0050] Next, when Beverage B is registered, the product name "Beverage B" is registered as shown in FIG. 7(d). Since "Beverage B" is a discounted product, the selection unit 20b selects from among the already registered products a product to which a bulk discount is applied when purchased in combination with "Beverage B". At this time, the selection unit 20b selects products in the order in which they were registered, so "Lunch Box A", which was registered first, is selected. The discount setting unit 20c then calculates that the discount amount for the bulk discount of "Beverage B" and "Lunch Box A" is "50 yen". The discount setting unit 20c selects "Beverage B" and "Lunch Box A" as a new product combination based on the fact that the calculated discount amount "50 yen" is greater than the discount amount "30 yen" calculated in FIG. 7(c). Then, the update unit 20d deletes the information "a" that was added to "Drink A" and "Lunch A" in the project column, and adds information "a" to "Drink B" and "Lunch A" indicating that they are a combination of products that are eligible for bulk sales. As a result, "Drink B" and "Lunch A" are selected as a new combination of products.

[0051] Furthermore, the selection unit 20b reselects whether the discount target product "Drink A" with the project column blank and the product eligible for bulk sales are registered. In the example of FIG. 7(d), "Drink A" and "Lunch Box B" are selected as a combination of products eligible for bulk sales. Then, the discount setting unit 20c calculates that the discount amount for the bulk discount of "Drink A" and "Lunch Box B" is "30 yen". The update unit 20d assigns information "b" to "Drink A" and "Lunch Box B" indicating that they are a combination of products eligible for bulk sales. As a result, "Drink A" and "Lunch Box B" are selected as a new combination of products. Furthermore, the total transaction amount "2070 yen" and the total discount amount "80 yen" are registered in the RAM 26.

[0052] In this manner, every time a new product is registered, the POS terminal device 10 repeats the process of selecting products to be included in the bulk sale, setting the discount amount, updating the product combination, and reselecting products to be included in the bulk sale.

[0053] (Explanation of the screen displayed on the cashier's display operation unit) Next, a screen displayed on the cashier-side display operation unit 5 will be described with reference to Fig. 8. Fig. 8 is a diagram showing an example of a screen displayed on the cashier-side display operation unit 5 by the POS terminal device 10.

[0054] Each time a new product is registered, the display control unit 20e displays registered product information 60 on the cashier-side display operation unit 5. The registered product information 60 includes a department 60a, a product name 60b, a unit price 60c, a quantity 60d, a discount 60e, and a price 60f.

[0055] The department 60a column displays information indicating that the combination of products selected for bulk sale is displayed, for example, in alphabetical order (a, b, ...). The product name 60b column displays the product name registered in the discount master 32 (see Figure 4). The unit price 60c column displays the unit price of the product registered in the discount master 32. The points 60d column displays the points of the product registered by the registration unit 20a (see Figure 3). The discount 60e column displays the amount obtained by adding a minus sign to the discount amount 32d at the time of the combination, which is registered in the discount master 32. The amount 60f column displays the amount of the product taking the discount amount into account.

[0056] In addition, in the column of the product name 60b, the name of the bulk discount campaign is displayed together with the product name. The campaign name is read and displayed from the campaign name 32e (see FIG. 4) registered in the discount master 32 in association with the product name.

[0057] The total number of registered items, the amount to be received from the customer, and the amount of change are displayed at the bottom of the cashier-side display operation unit 5. A message box 62 is provided at the bottom of the cashier-side display operation unit 5. The display control unit 20e displays necessary information for the cashier in the message box 62. For example, as shown in FIG. 8, the cashier's work is supported by displaying a message such as "Please give me your change."

[0058] (Explanation of the screen displayed on the customer side display) Next, a screen displayed on the customer display unit 7 will be described with reference to Fig. 9. Fig. 9 is a diagram showing an example of a screen displayed on the customer display unit 7 by the POS terminal device 10.

[0059] Each time a new product is registered, the display control unit 20e displays registered product information 70 on the customer side display unit 7. The registered product information 70 includes a department 70a, a product name 70b, a unit price 70c, a quantity 70d, a discount 70e, and a price 70f.

[0060] The department 70a column displays information indicating that the combination of products selected for bulk sale is displayed, for example in alphabetical order (a, b, ...). The product name 70b column displays the registered product name. The unit price 70c column displays the unit price of the product. The points 70d column displays the points of the registered product. The discount 70e column displays the discount amount. The amount 70f column displays the price of the product taking the discount amount into account.

[0061] The registered product information 70 first displays products that were not selected as items for the bulk sale, and then displays products that were selected as items for the bulk sale. Specifically, as shown in FIG. 9, the first line displays "Drink C," a product that was not selected as an item for the bulk sale. Then, the second and third lines, i.e., adjacent lines, display the first combination of "Lunch Box A" and "Drink A," and the fourth and fifth lines, i.e., adjacent lines, display the second combination of "Lunch Box B" and "Drink B." By displaying the registered product information 70 in this order, customers can easily recognize that discounts are being offered for bulk sales.

[0062] Furthermore, a message frame 72 is provided at the bottom of the customer-side display unit 7. The display control unit 20e displays necessary information in the message frame 72. For example, as shown in Fig. 9, a message such as "The discount amount is provisional. The discount amount will be updated according to the product registration" is displayed to deepen the customer's understanding.

[0063] Although an example has been shown in which the registered product information 60 displayed on the cashier's display operation unit 5 and the registered product information 70 displayed on the customer's display unit 7 are displayed in different formats, these are merely examples of display forms, and the registered product information 60 and the registered product information 70 may be displayed in the same format.

[0064] (Explanation of receipts printed by receipt printer) Next, the receipt printed and issued by the receipt printer 6 will be described with reference to Figure 10. Figure 10 shows an example of a receipt 90 printed and issued by the print control unit 20f (see Figure 3) of the POS terminal device 10.

[0065] The print control unit 20f prints on the receipt 90 information including the names 92a, 92b, and 92c of the products purchased by the customer and campaign information 94a and 94b indicating that a discount has been given for bulk sales.

[0066] As for the product names 92a, 92b, and 92c, the product that was not combined is printed first (at the top of the receipt 90). The products that were not combined are products that were not eligible for the bulk sale, and products that were eligible for the bulk sale but were not combined with conditional products and discounted products. For example, in the example of FIG. 10, the product name 92a, which is not eligible for the bulk sale, is printed first.

[0067] After that, the print control unit 20f prints the combined product names in succession. In the example of Fig. 10, "Lunch Box A" and "Drink A" are printed in succession as the product name 92b. Also, "Lunch Box B" and "Drink B" are printed in succession as the product name 92c.

[0068] Furthermore, the print control unit 20f prints campaign information 94a after the product name 92b. Also, the print control unit 20f prints campaign information 94b after the product name 92c. The campaign information 94a and 94b include the campaign name and the discount amount for the bulk sale.

[0069] In addition, the print control unit 20f also prints on the receipt 90 the subtotal, total, deposit amount, change amount, etc.

[0070] As described above, according to the POS terminal device 10 (product sales data processing device) of the embodiment, the registration unit 20a (registration means) executes the registration process of the products to be sold to the customer, and the selection unit 20b (selection means) selects a combination of products to be the subject of the bulk sale from among the registered products based on information indicating whether the products are the subject of the bulk sale. Then, the discount setting unit 20c (discount means) sets a discount amount according to the combination of products selected by the selection unit 20b, and the update unit 20d (update means) updates the combination of products and the discount amount when the selection unit 20b selects a combination of products with a larger discount amount. Therefore, the combination of products to be the subject of the bulk sale can be flexibly set.

[0071] According to the POS terminal device 10 of the embodiment, the selection unit 20b, the discount setting unit 20c, and the update unit 20d operate every time the registration unit 20a registers a product. Therefore, every time a new product is registered, the product combination that provides the maximum discount amount at that time is selected, so that the cashier and the customer can quickly check the discount amount for the bulk sale.

[0072] According to the POS terminal device 10 of the embodiment, the selection unit 20b selects a combination of products to be sold in a bundle from among the registered products each time the registration unit 20a registers products, and when the update unit 20d updates a product combination, selects a combination of products to be sold in a bundle from among the registered products that are not included in a bundle sale combination. Therefore, each time a new product is registered, a combination of products to be sold in a bundle that will maximize the discount amount can be selected.

[0073] Furthermore, according to the POS terminal device 10 of the embodiment, the cashier-side display operation unit 5 (cashier-side display means) displays information including the combination of products selected as the target of the bulk sale to the cashier operating the POS terminal device 10 (product sales data processing device). Furthermore, the customer-side display unit 7 (customer-side display means) displays information including the combination of products selected as the target of the bulk sale to the customer. Therefore, information including the combination of products that are the target of the bulk sale can be presented to both the cashier and the customer.

[0074] Furthermore, according to the POS terminal device 10 of the embodiment, the print control unit 20f (printing means) prints and issues information including the combination of products selected as the target of the bulk sale on the receipt 90. Therefore, the combination of products targeted for the bulk sale can be printed on the receipt 90 in a format that is easy for the customer to understand.

[0075] Although the embodiment of the present invention has been described above, this embodiment is merely an example and is not intended to limit the scope of the invention. This novel embodiment can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the invention and its equivalents described in the claims.

[0076] For example, the control program P1 executed by the control unit 20 may be provided in a state stored in the storage unit 30, or may be provided by being recorded in an installable or executable file format on a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a digital versatile disk (DVD).
