Description

Embodiments of the present invention relate to a product sales data processing device and a control program for causing a computer to function as the device.

Regarding the tax system in which taxes are imposed on the consumption of products, there is a so-called reduced tax rate system that holds tax rates lower on products that are directly involved in daily life, such as beverages and foods, than on other products. Under the reduced tax rate system, the tax rate on products eligible for the reduced tax rate is lower than the regular tax rate on products that are not eligible. However, even if a product is eligible for the reduced tax rate, it may not be applicable depending on the form of consumption. For example, if the product eligible for the reduced tax rate is defined as "beverages or food items other than eating out," if the drink or food item purchased at a store is taken home, it is not eligible for the reduced tax rate. Become. However, in the case of eating and drinking beverages or foodstuffs inside the store, so-called eating and drinking in the store, it is treated as eating out and is therefore not eligible for the reduced tax rate.

It is up to the consumer to decide whether to take the purchased beverages or foods home or to eat and drink them in the store. For this reason, at stores, store clerks in charge of accounting verbally confirm with consumers who have purchased foodstuffs etc. that are subject to the reduced tax rate whether they are taking them home or eating in the store. In the case of in-store dining, it is necessary to manipulate product sales data such as POS (Point Of Sales) so that the product sales data is processed at the regular tax rate rather than the reduced tax rate.

Hereinafter, an embodiment of a product sales data processing device that can easily cope with the case where the tax rate imposed on the consumption of a product changes depending on the form of consumption will be described with reference to the drawings.
In addition, in this embodiment, "beverages or food products other than eating out" are subject to the reduced tax rate. In other words, the tax rate levied on beverages or foods is a reduced tax rate in the case of take-out, but a normal tax rate in the case of in-store dining. A POS (Point Of Sales) terminal installed at a checkout location of a retail store equipped with an eat-in space will be exemplified as an example of a product sales data processing device.

FIG. 1 is a block diagram showing the main circuit configuration of a POS terminal 1 according to an embodiment. The POS terminal 1 includes a scanner 2 and a terminal main body 3.

The scanner 2 functions as a reading device that reads information that identifies products provided to consumers, so-called product identification information. In order to realize this function, the scanner 2 includes an imaging device 21, a controller 22, and a storage device 23. The imaging device 21 captures an image of a product held over a reading window (not shown). The controller 22 analyzes the image captured by the imaging device 21 and reads product identification information. The product identification information is information on the barcode attached to the product. Product identification information is not limited to barcode information. The product identification information may be information on a two-dimensional data code, character information, information regarding the appearance feature amount of the product, or the like. The controller 22 outputs a data signal including product identification information to the terminal body 3. The storage device 23 stores data necessary for image analysis by the controller 22.

The terminal body 3 functions as a data processing device that processes data related to product sales. In order to realize this function, the terminal body 3 includes a processor 31, a main memory 32, an auxiliary storage device 33, a clock 34, an input device 35, a first display device 36, a second display device 37, a scanner interface 38, and a printer 39. , a communication interface 310 and a system transmission path 311. The system transmission line 311 includes an address bus, a data bus, a control signal line, and the like. The terminal body 3 includes a system transmission path 311, a processor 31, a main memory 32, an auxiliary storage device 33, a clock 34, an input device 35, a first display device 36, a second display device 37, a scanner interface 38, a printer 39, and a communication device. Connect the interface 310. In the terminal main body 3, a computer is configured by a processor 31, a main memory 32, an auxiliary storage device 33, and a system transmission path 311 connecting these.

The processor 31 corresponds to the central part of the computer. The processor 31 controls each part to realize various functions of the POS terminal 1 according to an operating system or an application program. The processor 31 is, for example, a CPU (Central Processing Unit).

The main memory 32 corresponds to the main memory portion of the computer. Main memory 32 includes a nonvolatile memory area and a volatile memory area. The main memory 32 is a nonvolatile memory area that stores an operating system or application programs. The main memory 32 may store data necessary for the processor 31 to execute processing for controlling each unit in a non-volatile or volatile memory area. The main memory 32 uses a volatile memory area as a work area in which data is appropriately rewritten by the processor 31. The nonvolatile memory area is, for example, a ROM (Read Only Memory). The volatile memory area is, for example, RAM (Random Access Memory).

The auxiliary storage device 33 corresponds to the auxiliary storage portion of the computer. For example, the auxiliary storage device 33 may be an EEPROM (registered trademark) (Electric Erasable Programmable Read-Only Memory), an HDD (Hard Disc Drive), or an SSD (Solid State Drive). The auxiliary storage device 33 stores data used by the processor 31 in performing various processes, data created by processing by the processor 31, and the like. The auxiliary storage device 33 may also store the above application program.

The application program includes a control program. That is, the control program is stored in the main memory 32 or the auxiliary storage device 33 and executed by the processor 31. Note that the method of installing the control program into the main memory 32 or the auxiliary storage device 33 is not particularly limited. The control program can be recorded on a removable recording medium or distributed by communication via a network and installed in the main memory 32 or the auxiliary storage device 33. The recording medium may be in any form as long as it can store the program and is readable by the device, such as a CD-ROM or a memory card.

The clock 34 functions as a time information source for the terminal body 3. The processor 31 measures the current date and time based on time information measured by the clock 34.

The input device 35 receives operation input from the operator of the POS terminal 1. The input device 35 is, for example, a keyboard. The input device 35 may be, for example, a touch panel.

The first display device 36 displays an image to the operator of the POS terminal 1. The image may be a registered image showing data of a product registered for sale as a purchased product by a customer who is a consumer, or an accounting image showing data related to the customer's accounting, such as the total amount of purchased products. The second display device 37 displays images to the customer. The image is the above-mentioned registered image, accounting image, or the like. The first display device 36 and the second display device 37 are examples of display means that display product information. The first display device 36 and the second display device 37 are, for example, liquid crystal displays. The screen sizes of the displays may be the same or different between the first display device 36 and the second display device 37.

The scanner interface 38 performs data communication with the scanner 2. The scanner interface 38 receives the data signal output from the scanner 2.
The printer 39 prints data on products registered for sale as purchased products on a roll of receipt paper. Receipt paper with product data printed on it is cut for each customer and issued as a receipt. The printer 39 is an example of an issuing unit that issues a receipt on which product information is recorded.

The communication interface 310 performs data communication with an external device connected via a communication network 4 such as a LAN (Local Area Network). External equipment includes a store server 5. The store server 5 is a server computer equipped with a product master file 51, a tax rate table 52, and the like. A POS system is configured by a store server 5 controlling a plurality of POS terminals 1 connected via a communication network 4. Since such a POS system is well known, a description thereof will be omitted here.

FIG. 2 is a schematic diagram showing the main data structure of the product record 51R stored in the product master file 51. The product master file 51 stores product records 51R generated for each product sold at the store. The product record 51R includes a product code, classification code, product name, price, tax exemption flag F1, reduction target flag F2, eating out target flag F3, and the like.

The product code is a unique code set for each product to identify each product. Each product has a barcode symbol printed on it, which is a barcode of the product code. Alternatively, a label with a barcode symbol printed on it is affixed to each product. A classification code is a unique code assigned to a product classification. Each product is assigned to one of the product categories based on its attributes. Product classifications include, for example, beverages, foods, daily necessities, magazines and books, and the like. The product name and price are the name of the product identified by the product code and the sales amount per item.

The tax exemption flag F1 is 1-bit information for identifying whether the product identified by the product code is a tax exempt item. In this embodiment, the tax-free flag F1 is set to "1" for products that are tax-exempt items, and the tax-free flag F1 is set to "0" for products that are taxable items.

The reduction target flag F2 is 1-bit information for identifying whether the product identified by the product code is a product eligible for the reduced tax rate. In this embodiment, the reduction target flag F2 is set to "1" for products that are subject to the reduced tax rate, and the reduction target flag F2 is set to "0" for products that are not subject to the reduced tax rate.

The eating out target flag F3 is 1-bit information for identifying whether or not the product identified by the product code is treated as eating out when eaten in the eat-in space. In this embodiment, when a consumer purchases food items such as boxed lunches, rice balls, bread, and side dishes, and eats them in an eat-in space within a store, the purchase is treated as eating out. Other food items such as sweets and fresh foods are not treated as eating out even if eaten in the eat-in space. In this way, even if the products are subject to the reduced tax rate, that is, beverages or foodstuffs, it is assumed that there is a mixture of products that can be treated as eating out and products that cannot be treated as eating out. For products that can be treated as eating out, the eating out flag F3 is set to "1", and for products that cannot be treated as eating out, the eating out flag F3 is set to "0". Note that the criteria for determining whether or not to treat food as eating out is not limited to this.

FIG. 3 is a schematic diagram showing the data structure of the tax rate table 52. The tax rate table 52 has a normal tax rate area 52A and a reduced tax rate area 52B. The normal tax rate area 52A describes the normal tax rate of the tax system under which tax is imposed on the consumption of products. The reduced tax rate area 52B describes the reduced tax rate of the same tax system. In this embodiment, the normal tax rate is 10% and the reduced tax rate is 8%. The data of the tax rate table 52 is distributed to the store server 5, and is also downloaded and stored in the main memory 32 of the terminal body 3 and the storage device 23 of the scanner 2.

FIGS. 4 and 5 are schematic diagrams showing the barcode symbol 61 and its surroundings attached to products that can be treated as eating out among products eligible for the reduced tax rate. FIG. 4 shows a first state in which a second sticker 8 is affixed to cover the first sticker 7 affixed to the product, and FIG. 5 shows a second state in which the second sticker 8 is removed. It shows.

Hereinafter, for convenience of explanation, products that are subject to the reduced tax rate will be referred to as reduced-rate products. Among the reduction target products, products that can be treated as eating out products are referred to as eating out eligible products.

In FIG. 4 or 5, a barcode symbol 61 represents a 13-digit product code [4901234567890] in accordance with the JAN code standard. The product code includes a country code, manufacturer code, product item code, check digit, etc. Incidentally, the barcode symbol 61 is attached not only to products eligible for eating out, but also to products eligible for reduction other than products eligible for eating out, and to regular products that are not subject to the reduced tax rate.

As shown in FIG. 4 or 5, in the product to be eaten out, a double-circle specific mark 62 is attached near the barcode symbol 61, in this embodiment, at the upper left as viewed from the figure. Further, a sealing area 63 is formed near the specific mark 62, in this embodiment at the upper right side of the figure. The area surrounding the barcode symbol 61, specific mark 62, and sticker area 63 is defined as the identification area 6 of the product to be eaten out.

The specific mark 62 is a mark for specifying that the product is a product eligible for eating out. The position where the specific mark 62 is attached is not limited to the position shown in FIG. 4 or FIG. 5. It may be pasted at any position within the identification area 6. Further, the shape of the specific mark 62 is not limited to that shown in FIG. 4 or FIG. 5 either. Any shape may be used as long as it does not affect the recognition of the barcode represented by the barcode symbol 61.

The seal area 63 is an area for attaching the first seal 7 and the second seal 8. In the sticker area 63, a first sticker 7 and a second sticker 8 are affixed to the product to which the specific mark 62 is attached, that is, the product to be eaten out. The position of the seal area 63 is determined based on the position of the specific mark 62. In the case of the example shown in FIG. 4 or 5, the rectangular area on the upper left of the specific mark 62 is the seal area 63. The shape and size of the seal area 63 are not limited to those shown in FIG. 4 or FIG. 5. In short, any area may be of a size that does not protrude from the identification area 6 and to which the first sticker 7 and the second sticker 8 can be attached.

As shown in FIG. 5, the first sticker 7 displays information indicating that the tax rate when the product is eaten in the eat-in space will be the regular tax rate of 10% instead of the reduced tax rate of 8%. . The first sticker 7 is attached to the product in the sticker area 63.

As shown in FIG. 4, information written on the second sticker 8 instructs the customer to peel off the second sticker 8 when eating the product in the eat-in space. The second sticker 8 is attached so as to cover the entire first sticker 7.

In this way, products to be eaten out are sold with a specific mark 62 affixed near the barcode symbol 61, and further with a first sticker 7 and a second sticker 8 affixed in the seal area 63. Then, the consumer who purchases the product for eating out and eats and drinks in the eat-in space peels off the second sticker 8. A consumer who takes home a product for eating out does not remove the second sticker 8. Note that, instead of the consumer peeling off the second sticker 8, the second sticker 8 may be peeled off by a clerk in charge of accounting who operates the POS terminal 1. Further, the store sells the product without pasting the first sticker 7 and the second sticker 8 in the sticker area 63. Then, when a consumer who purchases a product for eating out requests eating and drinking in the restaurant, a store clerk or the consumer may affix the first sticker 7 to the sticker area 63. In this case, the second seal 8 can be omitted, which is economical.

Now, the clerk in charge of accounting holds up the product that the consumer is purchasing over the reading window of the scanner 2. At this time, the store clerk holds the product over the reading window so that the barcode symbol 61 is imaged by the imaging device 21. In addition, especially for products to be eaten out, the store clerk holds the product over the reading window so that not only the barcode symbol 61 but also the specific mark 62 and seal area 63 are imaged by the imaging device 21. In other words, the store clerk holds the product up to the reading window so that the identification area 6 is photographed. When the store clerk holds the product over the reading window, the imaging device 21 of the scanner 2 captures an image of the product.

FIG. 6 is a flowchart showing the main operating procedures of the controller 22. The operation of the controller 22 will be described below using FIG. 6. Note that the contents of the process shown in FIG. 6 and described below are merely examples. The processing procedure and processing contents are not particularly limited as long as similar results can be obtained.

As Act 1, the controller 22 captures a frame image captured by the imaging device 21. Then, in Act 2, the controller 22 detects whether or not the barcode symbol 61 is displayed on the frame image. If the barcode symbol 61 is not displayed, the controller 22 determines NO in Act 2, and returns to Act 1. The controller 22 captures the next frame image from the imaging device 21.

If it is detected that the barcode symbol 61 is displayed on the frame image, the controller 22 determines YES in Act 2, and proceeds to Act 3. The controller 22 reads the product code from the barcode symbol 61 in Act 3. In Act 4, the controller 22 determines whether or not the product code has been successfully read. If reading the product code fails, the controller 22 determines NO in Act 4 and returns to Act 1. The controller 22 captures the next frame image from the imaging device 21. In this way, the controller 22 waits for the frame image in which the barcode symbol 61 from which the product code can be read is captured from the imaging device 21.

If the product code has been successfully read from the barcode symbol 61 displayed on the frame image, the controller 22 determines YES in Act 4 and proceeds to Act 5. In Act 5, the controller 22 detects whether or not the specific mark 62 is displayed on the frame image. If the specific mark 62 is not displayed, the controller 22 determines NO in Act 5, and proceeds to Act 6. The controller 22 generates the first communication data D1 (see FIG. 10) as Act6. In this manner, when the controller 22 captures a frame image in which the barcode symbol 61 from which the product code can be read is displayed but the specific mark 62 is not displayed, the controller 22 generates the first communication data D1. The first communication data D1 will be described later.

If the specific mark 62 is displayed on the frame image, the controller 22 determines YES in Act 5, and proceeds to Act 7. In Act 7, the controller 22 detects an image of the seal area 63 determined based on the position where the specific mark 62 is displayed.

In Act 8, the controller 22 detects whether the first seal 7 is displayed on the seal area 63. If the first sticker 7 is not displayed, the controller 22 determines NO in Act 8, and proceeds to Act 9. The controller 22 obtains the reduced tax rate from the tax rate table 52 as Act 9. If the first seal 7 is displayed in the seal area 63, the controller 22 determines YES in Act 8, and proceeds to Act 10. The controller 22 obtains the normal tax rate from the tax rate table 52 as Act 10. The tax rate table 52 is stored in the storage device 23.

If the reduced tax rate or the normal tax rate is obtained in Act 9 or Act 10, the controller 22 generates the second communication data D2 (see FIG. 10) as Act 11. In this manner, when the controller 22 captures a frame image in which the specific mark 62 is displayed together with the barcode symbol 61 from which the product code can be read, the controller 22 generates the second communication data D2.

FIG. 10 is a schematic diagram showing the data structure of the first communication data D1 and the second communication data D2. The first communication data D1 is composed of a 13-digit product code. That is, the first communication data D1 matches the barcode system of the JAN code standard. The product code is data read from the barcode symbol 61 in Act3.

The second communication data D2 includes a 13-digit product code, a 1-digit change flag, a 4-digit tax rate, a 1-digit tax type flag, and a 1-digit check digit. That is, the second communication data D2 matches the CODE-128 barcode system. The product code is data read from the barcode symbol 61 in Act3.

The change flag is data that identifies whether or not to change the tax rate. As mentioned above, in this embodiment, when the product to be eaten out is taken home, the tax rate is 8% of the reduced tax rate. However, if a product eligible for eating out is eaten inside the restaurant, it will be treated as eating out, so the tax rate will be changed from the reduced tax rate of 8% to the regular tax rate of 10%. When the tax rate is changed from the reduced tax rate to the normal tax rate, the change flag becomes "1". In other words, the change flag can be data that instructs to change the tax rate.

When a product to be eaten out is taken home, the second sticker 8 remains affixed to the seal area 63 of the product. However, when the product is to be eaten at a restaurant, the second seal 8 is peeled off and the first seal 7 appears in the seal area 63. That is, if the first sticker 7 is not displayed in the sticker area 63 of the image captured by the imaging device 21, the controller 22 determines that the item is to be taken home. In the case of take-out, the tax rate remains unchanged. At this time, the controller 22 obtains the reduced tax rate in Act9. Then, the controller 22 generates second communication data D2 with the change flag set to "0" and the tax rate set to the value of the reduced tax rate "8".

On the other hand, if the first seal 7 is displayed in the seal area 63 of the image captured by the imaging device 21, the controller 22 determines that the restaurant is a restaurant. For dine-in dining, the tax rate will change. At this time, the controller 22 obtains the normal tax rate in Act10. Then, the controller 22 generates second communication data D2 with the change flag set to "1" and the tax rate set to the normal tax rate value "10".

The tax type flag is data that identifies whether the tax-inclusive method or the tax-exclusive method is used. Whether the tax to be levied on the consumption of a product is tax-inclusive or tax-exclusive is determined by the store or its operating entity. In stores or operating entities that use the tax-inclusive method, the price of the product record 51R stored in the product master file 51 is the tax-inclusive price. In stores or operating entities that use the tax-excluded method, the price of the product record 51R is the tax-excluded price. In this embodiment, the tax type flag that specifies the tax-inclusive method is set to "1," and the tax type flag that specifies the tax-exclusive method is set to "0." The value of the tax type flag is stored in the storage device 23. The controller 22 reads the value of the tax type flag stored in the storage device 23 and incorporates it into the second communication data D2. Thereafter, the controller 22 calculates a check digit to complete the second communication data D2.

In this way, when the identification area 6 of a product to be eaten out is captured by the imaging device 21 with the second sticker 8 affixed, the controller 22 records the product code of the product to be eaten out, the change flag of "0", Second communication data D2 including a tax rate of "8" and a tax type flag of "0" or "1" is generated. When the identification area 6 of the product to be eaten out is captured by the imaging device 21 with the second sticker 8 peeled off and the first sticker 7 exposed, the controller 22 captures the product code of the product to be eaten out and the “ Second communication data D2 including a change flag of "1", a tax rate of "10", and a tax type flag of "0" or "1" is generated.

Returning to the explanation of FIG. 6.
After the controller 22 finishes generating the first communication data D1 or the second communication data D2 in Act6 or Act11, the controller 22 proceeds to Act10. The controller 22 outputs the generated first communication data D1 or second communication data D2 to the terminal main body 3 as Act10. After that, the controller 22 returns to Act1. The controller 22 captures the next frame image from the imaging device 21.

In this way, the scanner 2 functioning as a reading device reads the product code, which is product identification information, from the information of the barcode symbol 61 included in the image of the product held over the reading window. Here, if the specific mark 62 is not displayed on the image, the scanner 2 generates the first communication data D1 and outputs it to the terminal main body 3.

On the other hand, if the specific mark 62 is displayed on the image and the first seal 7 is displayed in the seal area 63 specified by the specific mark 62, the scanner 2 changes the state to instruct a change in the tax rate. Second communication data D2 including the flag is generated and output to the terminal body 3. If the first sticker 7 is not displayed in the sticker area 63, the scanner 2 generates second communication data D2 including a change flag that does not instruct a change in the tax rate, and outputs it to the terminal body 3. . In this way, the first communication data D1 or the second communication data D2 is output from the scanner 2 to the terminal main body 3 every time the product code is read.

Note that the technology for recognizing the barcode symbol 61, the specific mark 62, the first seal 7, etc. from the image captured by the imaging device 21 is possible by using a well-known pattern recognition technology or the like. Therefore, the explanation here will be omitted.

7 to 9 are flowcharts showing main procedures of information processing executed by the processor 31 of the terminal main body 3 according to the above-described control program. The operation of the terminal main body 3 will be described below using FIGS. 7 to 9. Note that the contents of the processes shown in FIGS. 7 to 9 and described below are merely examples. The processing procedure and processing contents are not particularly limited as long as similar results can be obtained.

The processor 31 waits for a data signal from the scanner 2 in Act 21. Upon receiving the data signal output from the scanner 2 at the scanner interface 38, the processor 31 determines YES in Act 21 and proceeds to Act 22. The processor 31 identifies whether the data signal received in Act 22 is a signal of the first communication data D1 or a signal of the second communication data D2.

If the pattern of the data signal matches that of the barcode system of the JAN code standard, the data signal is a signal of the first communication data D1. If the pattern of the data signal matches that of the CODE-128 barcode system, the data signal is a signal of the second communication data D2.

When the signal of the first communication data D1 is received from the scanner 2, the processor 31 determines YES in Act 22, and proceeds to Act 23. The processor 31 extracts the product code from the first communication data D1 as Act23. Then, in Act 24, the processor 31 accesses the store server 5 and obtains the product record 51R including the product code from the product master file 51.

In Act 25, the processor 31 examines the tax exemption flag F1 included in the product record 51R. Here, if the tax exemption flag F1 is "1", that is, if the product code of the tax exempt product is read by the scanner 2, the processor 31 determines YES in Act 25, and proceeds to Act 34. The processing in Act 34 will be described later.

In Act 25, if the tax exemption flag F1 is "0", that is, if the product code of the taxable product is read by the scanner 2, the processor 31 determines NO and proceeds to Act 26. The processor 31 checks the reduction target flag F2 included in the product record 51R in Act26. Here, if the reduction target flag F2 is "0", that is, if the product code of a product that is not eligible for reduction is read by the scanner 2, the processor 31 determines NO in Act 26, and proceeds to Act 27. . The processor 31 obtains the normal tax rate from the tax rate table 52 as Act 27. Thereafter, the processor 31 proceeds to Act30. The processing in Act 30 will be described later.

In Act 26, if the reduction target flag F2 is "1", that is, if the product code of the reduction target product is read by the scanner 2, the processor 31 determines YES and proceeds to Act 28. In Act 28, the processor 31 checks the eating out target flag F3 included in the product record 51R.

Here, if the eating out target flag F3 is "1", that is, if the product code of the eating out target product is read by the scanner 2, the processor 31 determines YES in Act 28, and makes an error.

In the case of a product to be eaten out, the first communication data D1 is generated by the scanner 2 and is not output to the terminal main body 3. Therefore, in Act28, which is a part of the process when the first communication data D1 is received, the fact that the eating out target flag F3 is "1" indicates an abnormal state. A possible cause of this situation is, for example, when the product is held up to the reading window, the barcode symbol 61 is recognized, but the specific mark 62 is not. Alternatively, it is also assumed that the specific mark 62 pasted on the identification area 6 has peeled off. If the specific mark 62 is not recognized by the scanner 2, it cannot be determined whether the product to be eaten out is a take-out item or a dine-in item. Therefore, the processor 31 treats the read product code as an error and cancels subsequent processing.

In Act 28, if the eating out target flag F3 is "0", the processor 31 determines NO and proceeds to Act 29. The processor 31 obtains the reduced tax rate from the tax rate table 52 as Act 29. Thereafter, the processor 31 proceeds to Act30.

In this way, when the processor 31 acquires the normal tax rate from the tax rate table 52 in Act 27 or acquires the reduced tax rate in Act 29, it proceeds to Act 30. The tax rate table 52 is stored in the main memory 32. The processor 31 may refer to the tax rate table 52 of the store server 5.

In Act 30, the processor 31 confirms whether the tax imposed on the consumption of the product is an exclusive tax system or an inclusive tax system. Information regarding this tax is stored in advance in the auxiliary storage device 33. In the case of the tax-inclusive method, the processor 31 determines NO in Act 30 and proceeds to Act 31. The processor 31 calculates the tax included amount R1 included in the price P1 from the price P1 included in the product record 51R as Act 31 and the tax rate Q1 acquired in Act 27 or Act 29. The included tax amount R1 is calculated using the following formula (1).
R1=P1-[P1/(1+Q1)]...(1)
After calculating the included tax amount R1, the processor 31 proceeds to Act34.

On the other hand, in the case of the tax-exclusive method, the processor 31 determines YES in Act 30 and proceeds to Act 32. The processor 31 calculates the tax-excluded amount R2 as Act32. The tax-excluded amount R2 is calculated using the following formula (2), where the price is expressed as P1 and the tax rate is expressed as Q1.
R2=P1*Q1...(2)
After calculating the tax-exclusive price R2, the processor 31 calculates the tax-inclusive price P2 in Act 33. The tax-inclusive price P2 is calculated using the following formula (3).
P2=P1+R2...(3)
After calculating the tax-included price P2, the processor 31 proceeds to Act34.

In this way, when the processor 31 determines that the item is not taxed in Act 25 or calculates the tax-inclusive price R1 or the tax-inclusive price P2 in Act 31 or Act 33, the processor 31 proceeds to Act 34.

The processor 31 performs product sales data registration processing in Act34. The registration process differs depending on whether the item is determined to be exempt from tax, the case where the tax-inclusive amount R1 is calculated, or the case where the tax-inclusive price P2 is calculated together with the tax-exclusive amount R2. If it is determined that the product is not taxed, the processor 31 generates product sales data including the product code and price P1 of the product record 51R, and registers it in the registration area of the main memory 32. When the tax-included amount R1 is calculated, the processor 31 generates product sales data including the product code of the product record 51R, the price P1, and the tax-included amount R1, and registers it in the registration area. When the tax-inclusive price P2 is calculated together with the tax-inclusive price R2, the processor 31 generates product sales data including the product code of the product record 51R, the tax-inclusive price P3, and the tax-inclusive price R2, and registers it in the registration area.

Note that whether the tax imposed on the consumption of a product is tax-inclusive or tax-exclusive is determined by the store or its operating body, as described above. Therefore, a routine in which the judgment is NO in Act 30 and the tax-inclusive price R1 is calculated and a routine in which the judgment is YES in Act 30 and the tax-inclusive price R2 and the tax-inclusive price P2 are not mixed together.

After completing the product sales data registration process, the processor 31 performs product sales data display processing in Act 35. Specifically, the processor 31 causes the first display device 36 and the second display device 37 to display the product name and price P1 or tax-included price P2 of the product record. The processor 31 may also cause the first display device 36 or the second display device 37 to display information other than the product name or price.

After completing the product sales data display process, the processor 31 ends the process performed when receiving the first communication data D1. The processor 31 then waits to receive the next data.

Return to Act 22.
When the signal of the second communication data D2 is received from the scanner 2, the processor 31 determines NO in Act 22, and proceeds to Act 41 in FIG. 8. The processor 31 extracts the product code from the second communication data D2 as Act41. Then, in Act 42, the processor 31 accesses the store server 5 and obtains the product record 51R including the product code from the product master file 51.

In Act 43, the processor 31 checks the eating out target flag F3 included in the product record 51R. As described above, the scanner 2 generates the second communication data D2 in the case of a product to be eaten out, and outputs it to the terminal main body 3. For products other than products to be eaten out, first communication data D1 is generated and output to the terminal main body 3. Therefore, when the signal of the second communication data D2 is received from the scanner 2, the eating out target flag F3 included in the product record 51R must be "1".

However, if the eating out target flag F3 is "0", the processor 31 determines NO in Act 43, and proceeds to Act 44. For example, if the specific mark 62 is erroneously affixed to a product other than the product eligible for eating out, the eating out eligible flag F3 may become "0". In this case, the processor 31 issues a warning in Act44. For example, the processor 31 causes the first display device 36 to display a warning message such as "Products other than those eligible for eating out have been marked with a specific mark." Note that the processor 31 may notify by sound or light that a specific mark is attached to a product other than the edible product.

When the clerk in charge of accounting who operates the POS terminal 1 receives the warning, he operates the input device 35 to input for confirmation. For example, if the input device 35 is a keyboard, a confirmation key is pressed. For example, if the input device 35 is a touch panel, a confirmation soft key on the display screen is touched.

The processor 31 waits for a confirmation input to be made in Act 45. When the input for confirmation is made, the processor 31 determines YES in Act 45, and proceeds to Act 25 in FIG. Then, the processor 31 executes the processes in Acts 25 to 34 in the same manner as described above. That is, the processor 31 executes registration processing, display processing, etc. for products other than products to be eaten out.

In Act 43, if the eating out target flag F3 is "1", the processor 31 determines YES and proceeds to Act 46. The processor 31 checks the change flag included in the second communication data D2 as Act46. If the change flag is "0", that is, if a tax rate change is not instructed, the processor 31 determines NO in Act 46, and proceeds to Act 47. The processor 31 obtains the reduced tax rate from the tax rate table 52 as Act 47. Thereafter, the processor 31 proceeds to Act48.

In Act 48, the processor 31 confirms whether the tax imposed on the consumption of the product is an exclusive tax system or an inclusive tax system. In the case of the tax-inclusive method, the processor 31 determines NO in Act 48 and proceeds to Act 49. The processor 31 calculates the tax included amount R1 included in the price P1 using the formula (1) above from the price P1 included in the product record 51R as Act 49 and the tax rate Q1 acquired in Act 47. After calculating the included tax amount R1, the processor 31 proceeds to Act52.

On the other hand, in the case of the tax-exclusive method, the processor 31 determines YES in Act 48 and proceeds to Act 50. As Act 50, the processor 31 calculates the tax-excluded amount R2 from the price P1 and the tax rate Q1 using the formula (2). After calculating the tax-excluded amount R2, the processor 31 calculates the tax-included price P2 using the formula (3) in Act 51. After calculating the tax-included price P2, the processor 31 proceeds to Act52.

In this way, when the tax-included amount R1 is calculated in Act 49 or the tax-included price P2 is calculated in Act 51, the processor 31 proceeds to Act 52. The processor 31 performs product sales data registration processing in Act 52. Furthermore, the processor 31 performs display processing of product sales data as Act 53. This registration process and display process are similar to the processes in Acts 34 and 35, so a detailed explanation will be omitted here.

After completing the product sales data registration process and display process, the processor 31 ends the process performed when receiving the second communication data D2. The processor 31 then waits to receive the next data.

Return to Act 46.
When the change flag included in the second communication data D2 is "1", that is, when a tax rate change is instructed, the processor 31 determines YES in Act 46, and proceeds to Act 61 in FIG. 9. In Act 61, the processor 31 confirms whether the tax imposed on the consumption of the product is an exclusive tax system or an inclusive tax system. In the case of the tax-inclusive method, the processor 31 determines YES in Act 61 and proceeds to Act 62. The processor 31 obtains the reduced tax rate from the tax rate table 52 as Act62. In addition, the processor 31 calculates the tax-excluded price P3 for the price P1 included in the product record 51R as Act 63.

As described above, in the case of the tax-inclusive method, the price P1 stored in the product master file 51 includes the tax-inclusive amount. Therefore, the processor 31 calculates the tax-excluded price P3 using the reduced tax rate acquired in Act62. The tax-excluded price P3 is calculated by the following formula (3), where the reduced tax rate is represented by Q2.
P3=P1/(1+Q2)...(3)
After calculating the tax-excluding price P3, the processor 31 proceeds to Act64.

On the other hand, if the tax imposed on the consumption of the product is tax-excluded, the price P1 stored in the product master file 51 is the tax-excluded price P3. Therefore, the processor 31 determines NO in Act61, skips the processing in Act62 and Act63, and proceeds to Act64.

The processor 31 obtains the normal tax rate from the tax rate table 52 as Act64. Then, in Act 65, the processor 31 calculates the tax-excluded amount R3 from the tax-excluded price P3 and the normal tax rate. The exclusive tax amount R3 is calculated using the following formula (4), where the normal tax rate is expressed as Q3. R3=P3*Q3...(4)
After calculating the tax-exclusive amount R3, the processor 31 calculates the tax-inclusive price P4 from the tax-exclusive price P3 and the tax-exclusive price R3. The tax-inclusive price P4 is calculated using the following formula (5).
P4=P3+R3...(5)
After calculating the tax-included price P4, the processor 31 performs product sales data registration processing in Act 67. Further, the processor 31 performs display processing of product sales data as Act 68. This registration process and display process are similar to the processes in Acts 34 and 35, so a detailed explanation will be omitted here.

After completing the product sales data registration process and display process, the processor 31 ends the process performed when receiving the second communication data D2. The processor 31 then waits to receive the next data.

FIG. 11 shows a case where a food-out product with the product name "AAA" is taken home at a tax-inclusive store, that is, when the information in the identification area 6 is read by the scanner 2 without removing the second sticker 8. This is a display image SC1 of product sales data. FIG. 12 is a display image SC2 of product sales data when the same product is consumed in the same store, that is, when the second sticker 8 is peeled off and the information in the identification area 6 is read by the scanner 2. The display image SC1 and the display image SC2 are displayed on the first display device 36 under the control of the processor 31 as the first control means. Display image SC1 and display image SC2 may be displayed on second display device 37 under the control of processor 31.

As shown in FIG. 11, in the display image SC1, the product name "AAA" is displayed in the product name column AR1, the score "1" is displayed in the score column AR2, and the tax-included price "400 yen" is displayed in the price column AR3. The reduced tax rate "8%" is displayed in the tax rate column AR4, and the tax amount "30 yen" is displayed in the tax amount column AR5.

As shown in FIG. 12, in the display image SC2, the product name "AAA" is displayed in the product name column AR1, the score "1" is displayed in the score column AR2, and the tax-included price "407 yen" is displayed in the price column AR3. The normal tax rate "10%" is displayed in the tax rate column AR4, and the tax amount "37 yen" is displayed in the tax amount column AR5. Furthermore, a mark M1 indicating that the tax rate has been changed due to in-store dining is displayed in the product name column AR1.

Therefore, the clerk in charge of accounting can easily recognize that the product to be eaten in the store and eaten out has been correctly registered in the POS terminal 1 because the mark M1 is displayed in the product name field AR1. In other words, since the mark M1 is displayed in the product name field AR1, even if a take-out product to be eaten out is fraudulently registered in the POS terminal 1, the store clerk can easily recognize it.

Note that the display position of the mark M1 is not limited to the product name field AR1. For example, it may be the tax rate column AR4 or the tax amount column AR5. In short, it is sufficient that the store clerk or consumer who checks the display image SC2 can recognize that there has been a change in the tax rate.

FIG. 13 is an example of issuing a receipt RS1 when a product with the product name "AAA" to be eaten out is consumed in the restaurant and two products with the product name "BBB" and the product name "CCC" are taken home. The product name "BBB" is a product to which the normal tax rate is applied, and the product name "CCC" is a product eligible for reduction to which the reduced tax rate is applied. The receipt RS1 is printed and issued by the printer 39 under the control of the processor 31 as the second control means.

As shown in FIG. 13, for products that are dine-in or dine-in, a mark M2 indicating that the tax rate has been changed due to dine-in is printed along with the product name "AAA". Therefore, the consumer who receives the receipt RS1 can prove that the product with the product name "AAA" is correctly registered as an in-store food service.

As described in detail above, in the POS terminal 1, the identification means is configured by the computer mainly including the processor 31 of the terminal main body 3 executing the processes in Acts 21 to 23 in FIG. 7 and Act 41 in FIG. There is. Further, the acquisition means is configured by the same computer executing the processing in Acts 27 and 29 in FIG. 7 and the processing in Act 47 in FIG. 8. Further, the same computer executes the process of Act 46 in FIG. 8, thereby configuring the reception means. Further, the computer constitutes a calculation means by executing the processing in Acts 30 and 32 in FIG. 7, the processing in Acts 48 and 50 in FIG. 8, and the processing in Acts 61 and 65 in FIG. 9. Further, the same computer executes the processing in Act 34 in FIG. 7 and the processing in Act 52 in FIG. 8, thereby forming a processing means.

With the POS terminal 1 having such a configuration, even if the tax rate levied on the consumption of a product changes depending on the form of consumption, it can be done simply by deciding whether or not to remove the second sticker 8. , to be able to process sales data that includes the correct tax amount. In other words, when the form of consumption is take-out, the store clerk only needs to have the scanner 2 read the image of the identification area 6 without removing the second sticker 8. If the form of consumption is eating and drinking in the store, the store clerk may peel off the second sticker 8 and then read the image of the identification area 6 with the scanner 2. Note that the operator who causes the scanner 2 to read the image of the identification area 6 is not limited to a store clerk. The consumer may operate the scanner 2 himself/herself to read the image of the identification area 6.

As described above, according to the present embodiment, it is possible to provide a POS terminal 1 that can easily cope with the case where the tax rate imposed on the consumption of a product changes depending on the form of consumption.

Further, in the POS terminal 1, a computer mainly including the processor 31 of the terminal main body 3 constitutes a warning means by executing the processes in Acts 41 to 44 of FIG. Incidentally, in Act 43 of FIG. 8, when the second communication data D2 is received from the scanner 2, if the eating out target flag F3 included in the product record 51R is "0", the process proceeds to Act 44 and a warning is issued. I have to. The second communication data D2 includes a change flag as information indicating whether or not to change the tax rate. On the other hand, the fact that the eating out target flag F3 included in the product record 51R is "0" means that the product record 51R is data of a product that is not subject to tax rate change. Therefore, when the POS terminal 1 receives the second communication data D2 including the product code of a product not subject to a tax rate change and a change flag instructing a tax rate change, the POS terminal 1 issues a warning.

As described above, the POS terminal 1 of the present embodiment has the advantage of being able to prevent the inconvenience of registering a product with a changed tax rate for a product that is not subject to a tax rate change.

Further, the computer mainly including the processor 31 executes the processes in Acts 25 to 35 in FIG. 7 after the warning is canceled. That is, when the calculating means receives the second communication data D2 including the product code of a product not subject to a tax rate change and a change flag instructing a tax rate change, the calculation means calculates a value based on the price of the product and the tax rate obtained by the acquisition means. Calculating the tax amount. Therefore, according to the POS terminal 1, products can always be registered at the correct tax rate.

The embodiments of the product sales data processing device that can easily handle cases where the tax rate imposed on product consumption changes depending on the form of consumption have been described above, but such embodiments are not limited to this. do not have.

In the embodiment described above, the first sticker 7 affixed to the sticker area 63 has been described as having information indicating that the tax rate is 10% of the normal tax rate. In another embodiment, the first sticker 70 (see FIG. 14) may be used as a sticker that displays information indicating that the tax rate is 8% of the reduced tax rate. In this case, a second sticker 80 (see FIG. 14) that covers the first sticker 70 includes information that instructs the user to remove the second sticker 80 when taking the product home. be done. Further, in Act 8 of FIG. 6, the controller 22 of the scanner 2 determines NO when the first seal 70 is displayed in the seal area 63, and determines YES when the first seal 70 is not displayed. Bye.

FIG. 14 shows another embodiment in which a seal 90 formed by arranging the first seal 7 and the second seal 8 and the first seal 70 and the second seal 80 is attached to a product. In another embodiment, when taking the product to eat out to take home, the store clerk or the consumer peels off the second sticker 80 from the sticker 90. When a product to be eaten out is to be eaten inside the store, the store clerk or the consumer peels off the second sticker 8 from the sticker 90. In this way, in other embodiments, one of the second seals 8 or 80 must be peeled off for the product to be eaten out. Therefore, it is possible to prevent the store clerk from forgetting to check with the consumer.

In addition, in the case of other embodiments, the first sticker 7 or the first sticker 70 is projected near the barcode symbol 61 by the imaging device 21, whether the product is taken home or eaten inside the restaurant. An image is taken. Therefore, depending on whether the first seal 7 or the first seal 70 is displayed, it is possible to specify whether the product is a product to be eaten out. Therefore, the specific mark 62 may be omitted.
Note that the first seal 7 and the second seal 8 and the first seal 70 and the second seal 80 may be separately arranged and attached to the product for operation.

Moreover, in the embodiment, the first sticker 7 and the second sticker 8 are affixed in advance to the seal area 63 for the product to be eaten out. Regarding this point, before having the scanner 2 read the barcode symbol 61 of the product to be eaten out, the store staff confirms whether the product is to be eaten inside or taken out, and in the case of eating out, the first sticker 7 is pasted on the sticker area 63. You may. Alternatively, the first sticker 7 may be attached to the sticker area 63 when the consumer eats and drinks in the store. Alternatively, when taking the product home, a store clerk or a consumer may affix the first sticker 70 to the sticker area 63.

Further, in the above embodiment, a case is illustrated in which the first sticker 7 and the second sticker 8 are affixed to the seal area 63 and a specific mark 62 for specifying the position of this seal area 63 is affixed to the product to be eaten out. did. Regarding this point, it is also possible to omit the specific mark 62 by setting, for example, an area of a certain size around the barcode symbol 61 as the seal area 63 through programming.

Note that instead of the first seal 7 or the first seal 70, it is also possible to apply a two-dimensional data code or bar code dedicated to changing the tax rate.

In the embodiment, the second communication data D2 is composed of a product code, a change flag, a tax rate, a tax type flag, and a check digit. Among these items, information on the tax rate and tax type can be acquired by the terminal main body 3, and therefore does not necessarily have to be included in the second communication data D2. In other words, the second communication data D2 only needs to include at least a product code, which is product identification information, and a change flag, which is information indicating whether or not to instruct a change in the tax rate.

Furthermore, in the embodiment described above, the accepting means is a means for accepting whether or not a tax rate change is set based on a change flag. The reception means is not limited to this. For example, the accepting means may be a means for accepting whether a tax rate is set in the second communication data D2. In this case, the second communication data D2 only needs to include at least a product code, which is product identification information, and a tax rate.

Furthermore, the code system of the first communication data D1 and the second communication data D2 is not limited to the code system described in the embodiment. In short, the first communication data D1 only needs to be able to notify the terminal body 3 of information identifying the product provided to the consumer. The second communication data D2 only needs to be able to notify the terminal main body 3 of information identifying the product provided to the consumer and information instructing a change in the tax rate.

In the embodiment, the first display device 36 and the second display device 37 provided integrally with the terminal main body 3 have been described as an example of display means. The display means does not necessarily have to be provided integrally with the terminal main body 3. In that case, the computer of the terminal main body 3 constituting the processing means may output information on the product whose sales data has been processed to a display means provided separately to the terminal main body 3.

Although several other embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. These embodiments and modifications thereof are included within the scope of the invention, and are included within the scope of the invention described in the claims and its equivalents.
