JP-A-4-344996

  By the way, in recent years, the enforcement of the reduced tax rate system for consumption tax is being considered due to the tax reform. The reduced tax rate system is a system aimed at alleviating the relative burden of low-income earners by applying a reduced tax rate that is lower than the standard tax rate to daily necessities such as food. However, when such a reduced tax rate system is introduced, retailers need to update a point-of-sale (POS) system that performs accounting processing and sales management, which requires significant costs and time. Also, even after the reduced tax rate system comes into effect, the items subject to the reduced tax rate and the tax rate may change, which is expected to be a heavy burden on retailers. In the above Patent Document 1, when such a reduced tax rate system is introduced, detailed information of purchased products can be printed on the tax type, but it is necessary to update the electronic cash register (POS terminal). The burden on retailers cannot be improved.

  In view of the above problems, the present invention provides a control method for a printing control device, a receipt printer, and a printing control device that can reduce the retailer's cost burden and business burden associated with tax system revisions such as the enforcement of the consumption tax reduction tax rate system. The purpose is to provide.

  The printing control apparatus of the present invention obtains a print command including product information for specifying a purchased product from the terminal through the interface that communicates with a terminal that performs accounting processing, and refers to a tax rate database that indicates a tax rate of the product. And a control unit that determines a tax rate of the purchased product specified by the product information of the print command and generates print data for receipt printing based on the print command and the tax rate of the purchased product. And

  The control method of the print control apparatus of the present invention refers to a print command acquisition step for acquiring a print command including product information for specifying a purchased product from a terminal that performs accounting processing, and a tax rate database that indicates a tax rate of the product, and prints A tax rate determination step for determining the tax rate of the purchased product specified by the product information of the directive, and a print data generation step of generating print data for receipt printing based on the print command and the tax rate of the purchased product are executed. It is characterized by doing.

The present invention obtains a print command from a terminal (POS terminal) that performs accounting processing, determines a tax rate of a purchased product included in the print command, and generates print data for receipt printing. This makes it possible to issue a receipt in accordance with the tax system revision without requiring an update of the terminal that performs the accounting process and its peripheral system (POS system). That is, by using the printing control apparatus of the present invention, it is possible to reduce the retailer's cost burden and business burden associated with the tax system revision.
The “product information” may be information specifying the item of the purchased product, not the purchased product itself (single product).

  In the above print control apparatus, the print command includes money amount information based on the terminal accounting process result, and the control unit edits at least one of the product information and money amount information included in the print command based on the tax rate of the purchased product. Generated print data.

  According to the structure of this invention, the receipt which edited merchandise information and money amount information according to the tax system revision can be issued. The product information can be edited by adding a predetermined mark to the target product name of a predetermined tax rate such as a reduced tax rate, or listing the product name and its price by tax rate. In addition, the amount information may be edited by changing the amount charged (total amount) based on the determined tax rate.

  The printing control apparatus may further include a log storage unit that stores a log of print data generated by the control unit.

According to the configuration of the present invention, the retailer can use the stored print data log for tax procedures and the like.
The “print data log” refers to a record of print data generation processing or print processing history recorded in time series. Further, the “print data log” may be associated with the print data and the print data generation date and time, or may be associated with the print data and the print date and time.
In addition, the “print data log” may be stored only when the print command includes products subject to a predetermined tax rate, such as a reduced tax rate, or for all print commands regardless of purchased products. May be.

  In the print control apparatus, the control unit acquires personal information, and the log storage unit stores the personal information in association with each print data.

  The present invention can be used when personal information is required for tax procedures and the like.

  In the print control apparatus, the control unit outputs the print data stored in the log storage unit and log information which is personal information to an external device.

  The present invention can be used when a retailer needs to submit a log of print data to a tax office or the like. For example, in the reduced tax rate system for consumption tax, the tax office applies the reduced amount of products subject to reduced tax rate included in each print data from the log of print data provided by the retailer (applying the price when applying the standard tax rate-reduced tax rate) In this case, it is considered to calculate a price equivalent to the reduction amount and transfer it to the individual's bank account specified by the personal information.

  In the above print control apparatus, the control unit generates print data including personal information.

  The present invention can be used when an individual (customer) who purchased a product from a retailer needs to submit a receipt including personal information in a final tax return or the like. For example, in the reduced tax rate system for consumption tax, it is considered that individuals collect receipts including products subject to reduced tax rate and submit them to the tax office, etc., and transfer the refund to the individual's bank account at a later date. It can be used in any case.

  In the above-described printing control apparatus, when the determined tax rate of the purchased product is the first tax rate, the control unit determines the first price that is the price of the purchased product when the first tax rate is applied, and the first tax rate. A difference between the second price, which is the price of the purchased product when a different second tax rate is applied, is calculated, and print data including difference information indicating the difference is generated.

  According to the configuration of the present invention, for example, when the first tax rate is the reduced tax rate and the second tax rate is the standard tax rate, the individual (customer) determines the reduced amount of the product subject to the reduced tax rate from the difference information printed on the receipt. I can grasp it.

  In the above-described print control apparatus, when the print command includes a plurality of pieces of product information corresponding to a plurality of purchased products, the difference information indicates a sum of the differences calculated for the plurality of purchased products by the control unit. And

  According to the structure of this invention, the individual (customer) can grasp | ascertain the sum total of the reduction amount of all the reduction tax rate object goods purchased from the difference information printed on the receipt.

  In the above-described print control apparatus, when the specific information is included in the product information, the control unit determines that the tax rate of the purchased product specified by the product information is a specific tax rate corresponding to the specific information.

The present invention can be used even when the product information is the same, when the applicable tax rate differs depending on the sales situation, the sales date and the like.
The “specific information” may be information input by the operator to the terminal, or may be information automatically input according to the sales date and the like when outputting a print command from the terminal.

  The print control apparatus includes an interface that communicates with an external apparatus that stores a tax rate database via a network.

  According to the configuration of the present invention, a database provided by a predetermined organization such as the National Tax Agency can be used. This eliminates the need to update the tax rate database.

  The printing control apparatus includes a database storage unit that stores a tax rate database.

  According to the configuration of the present invention, since the tax rate database is incorporated in the print control apparatus, it is not necessary to provide a communication means for communicating with an external device that stores the tax rate database.

  The receipt printer of the present invention obtains a print command including product information for specifying a purchased product from the terminal through the interface that communicates with a terminal that performs accounting processing, and refers to a tax rate database that indicates the tax rate of the product. The control unit that determines the tax rate of the purchased product specified by the product information of the print command and generates the print data for receipt printing based on the print command and the tax rate of the purchased product, and the print data on the receipt paper And a printing unit for printing.

  According to the configuration of the present invention, since the tax rate is determined and the print data for receipt printing is generated by the receipt printer, it is not necessary to add a new terminal in accordance with the tax system revision. That is, it is not necessary to secure a space for installing a new terminal at the checkout counter.

  Hereinafter, a control method for a print control apparatus, a receipt printer, and a print control apparatus according to the present invention will be described with reference to the accompanying drawings. The receipt printer 1 of the present embodiment is assumed to be introduced in accordance with the enforcement of the reduced consumption tax rate system, and in conjunction with the previous POS system 10 that does not support the reduced tax rate system, the reduced tax rate A receipt R1 (see FIG. 5) corresponding to the system is issued.

  FIG. 1 is a system configuration diagram of a receipt issuing system SY that is an embodiment of the present invention. The receipt issuing system SY includes a receipt printer 1, a card reader 2, a POS terminal 3, a POS server 4, a first external server 5 (external device), and a second external server 6 (external device).

  The POS terminal 3 is a terminal that performs accounting processing and has a POS application 31. The POS application 31 calculates the total amount of purchased products purchased by the customer and generates a print command for printing the receipt R (receipt). The POS server 4 is connected to one or more POS terminals 3 and has a product database 41. The product database 41 is a database that associates the product code and price of each product. The POS system 3 is constructed by the POS terminal 3 and the POS server 4.

  Here, accounting processing by the POS terminal 3 will be briefly described. The POS terminal 3 acquires the product code of the purchased product using a bar code reader (not shown), etc., and reads the product name and price of the purchased product with reference to the product database 41. Moreover, the read prices are totaled, and the total amount is calculated by applying the subtotal per accounting and the consumption tax at the standard tax rate. Thereafter, accounting detail information including a list of product names and prices of each purchased product, subtotal, consumption tax, and total is generated, and a receipt R print command is issued to the receipt printer 1.

  FIG. 4 is a diagram illustrating a print example of the receipt R0 based on the print command. In the figure, product names such as “Aji” and “mackerel”, and prices such as “400 yen” and “600 yen” displayed on the same line as each product name specify the purchased product. Product information. The subtotal, consumption tax, and total are money amount information based on the accounting processing result of the POS terminal 3. As shown in the figure, the print command includes information such as a store name, a receipt number, and an issue date.

  On the other hand, the receipt printer 1 issues a receipt R based on the print command output from the POS terminal 3. In the present embodiment, if the purchased product includes a product targeted for the reduced tax rate, the print command is edited and a receipt R1 corresponding to the reduced tax rate as shown in FIG. 5 is issued. Further, if the purchased product does not include a product subject to the reduced tax rate, a conventional receipt R0 as shown in FIG. 4 is issued. Details will be described later.

  The receipt printer 1 is connected to a card reader 2 that reads a personal ID (personal information) from a personal ID card that identifies a customer. In addition, as personal ID, my number, the personal identification number linked | related with my number, the member number issued by a shop, etc. are applicable.

  Further, the receipt printer 1 is connected to the first external server 5 and the second external server 6 via a network NW such as the Internet. The first external server 5 and the second external server 6 are operated and managed by a government organization such as the National Tax Bureau or a private company entrusted by the government, and may be a common server.

  The first external server 5 has a tax rate database 51 indicating the tax rate of the product. The tax rate database 51 is a database indicating whether each product is subject to a standard tax rate or a reduced tax rate. In other words, it is a database in which product names are associated with tax rates. The “product” includes not only goods but also services. In the present embodiment, it is assumed that the standard tax rate is 10% and the reduced tax rate is 8%.

  The second external server 6 has a log information database 61 that stores log information. The log information is information that associates the print data generated by the receipt printer 1 with the personal ID of the individual who issued the receipt R. The receipt printer 1 generates log information for each accounting process (each time a print command is acquired from the POS terminal 3) and stores it in a predetermined storage area (ROM 73, see FIG. 2) in the receipt printer 1. . The stored log information is uploaded to the second external server 6 at a predetermined timing such as at the end of business or at the end of the month. In FIG. 1, only one receipt printer 1 connected to the second external server 6 is illustrated, but actually a plurality of receipt printers 1 are connected to the second external server 6. The log information database 61 stores log information uploaded from a plurality of receipt printers 1.

  Next, the hardware configuration of the receipt printer 1 will be described with reference to FIG. The receipt printer 1 includes a PC function unit 11 (printing control device) and a printer function unit 12. The PC function unit 11 includes a CPU (Central Processing Unit) 71, a RAM (Random Access Memory) 72, a ROM (Read Only Memory) 73, a peripheral device interface 74 (interface), a printer interface 75, and a LAN interface 76 (interface). .

  The CPU 71 controls the receipt printer 1 as a whole. The RAM 72 is used as a work area for the CPU 71. The ROM 73 is realized by, for example, a flash ROM, and stores the firmware of the receipt printer 1 and the log information described above.

  The peripheral device interface 74 is connected to the POS terminal 3 and the card reader 2 via a network or a dedicated cable. In the figure, they are collectively shown, but physically provided as individual interfaces. The connection form may be either wired connection or wireless connection. The printer interface 75 is connected to the printer function unit 12. The LAN interface 76 is connected to the network NW.

  On the other hand, the printer function unit 12 includes a printer interface 81, a head driver 82, a print head 83, a transport motor 84, a cutter motor 85, and a paper cutter 86. The printer interface 81 is connected to the PC function unit 11. The head driver 82 drives the print head 83. The print head 83 is a thermal head or an inkjet head, and the printing method is not limited. The conveyance motor 84 conveys roll paper (receipt paper) along the paper conveyance path that the print head 83 faces. The cutter motor 85 drives the paper cutter 86. The paper cutter 86 cuts the printed portion of the roll paper. The cut strip-shaped paper is issued as a receipt R.

  Next, functional configurations of the POS terminal 3 and the receipt printer 1 will be described with reference to FIG. The POS terminal 3 includes an accounting processing unit 310, a print command generation unit 320, and a print command output unit 330 as main functional configurations. These are functions mainly composed of the POS application 31.

  The accounting processor 310 refers to the product database 41 in the POS server 4 based on the product code of the purchased product purchased by the customer, acquires the product name and price, and calculates the total price of the purchased product. Perform accounting. The print command generation unit 320 generates a print command for printing the receipt R0 (see FIG. 4) based on the transaction processing result by the transaction processing unit 310. The print command includes product information for specifying the purchased product and its price, and money amount information based on the accounting process result. The print command output unit 330 outputs the print command generated by the print command generation unit 320 to the receipt printer 1. The receipt R0 output by the print command includes the name and price of the purchased product specified by the product information, and the number as the accounting process result indicated in the amount information. The print command may be in a command format or a markup language such as XML (Extensible Markup Language). Further, the merchandise information and the money amount information are not necessarily included in the receipt R0 output by the print command, and may be information that can be interpreted by the receipt printer 1.

  On the other hand, the receipt printer 1 includes a print command acquisition unit 110, a tax rate determination unit 120, a communication unit 130, a difference calculation unit 140, a personal information acquisition unit 150, a print data generation unit 160, a printing unit 170, a log, as main functional configurations. A storage unit 180 and a log output unit 190 are provided. Of these, the printing unit 170 is a function mainly composed of the printer function unit 12, and the other functions are mainly composed of the PC function unit 11. Among these, the print command acquisition unit 110, the tax rate determination unit 120, the difference calculation unit 140, the personal information acquisition unit 150, the print data generation unit 160, and the log output unit 190 correspond to the control unit 200.

  The print command acquisition unit 110 acquires a print command from the POS terminal 3 (print command acquisition step). The communication unit 130 communicates with the first external server 5 that stores the tax rate database 51. The tax rate determination unit 120 refers to the tax rate database 51 via the communication unit 130 and determines the tax rate of one or more purchased products specified by the one or more product information included in the print command (tax rate determination step). In this embodiment, it is determined whether each purchased product has a tax rate of 8% (reduced tax rate) or a tax rate of 10% (standard tax rate).

  When the tax rate of the purchased product determined by the tax rate determining unit 120 is the reduced tax rate (first tax rate), the difference calculating unit 140 uses the first price that is the price of the purchased product when the reduced tax rate is applied, and the standard price The difference between the second price, which is the price of the purchased product when the tax rate (second tax rate) is applied, is calculated. In addition, when the print command includes a plurality of pieces of product information corresponding to a plurality of purchased products, the difference calculation unit 140 sums the differences calculated for the plurality of purchased products (that is, the tax-excluded sum of the plurality of purchased products). (Amount obtained by multiplying the amount of money by the difference between the first tax rate and the second tax rate). For example, in the example of the receipt R1 shown in FIG. 5, the product with “*” added to the product name is the product subject to the reduced tax rate (see reference numeral 91), but the total amount “1300 yen” is reduced to the reduced tax rate and the standard tax rate. Calculate the amount of “26 yen” multiplied by the tax rate difference of “2%”. This “26 yen” is the amount refunded to the customer when the reduced tax rate system is in effect (see reference numeral 92). Various proposals have been considered for the refund method. In this embodiment, it is assumed that the customer can receive a refund by submitting a receipt to the tax office or the like. On the other hand, the personal information acquisition unit 150 acquires the customer's personal ID (personal information) read by the card reader 2.

  The print data generation unit 160 generates print data based on the print command acquired by the print command acquisition unit 110 and the tax rate of the purchased product determined by the tax rate determination unit 120 (print data generation step). Specifically, the product information included in the print command is edited based on the tax rate of the purchased product. In the present embodiment, as shown in the receipt R1 in FIG. 5, editing is performed by adding “*” to the head of the product name (see reference numeral 91). Note that a dotted frame shown on the receipt R, such as reference numeral 91, indicates an edit target area. The print data generation unit 160 also generates print data including difference information indicating the difference calculated by the difference calculation unit 140 and personal information acquired by the personal information acquisition unit 150. In the present embodiment, as shown in the receipt R1 of FIG. 5, the reduced information including the reduced tax rate and the total amount before tax of the reduced tax rate target product are included in the print data as the difference information (see reference numeral 92). Further, the personal ID read from the customer's personal ID card is included in the print data as the personal information (see reference numeral 93). The printing unit 170 prints the print data generated by the print data generation unit 160 on roll paper (receipt paper). Note that at least one of the difference information and the personal information may be printed as a code image such as a barcode or a two-dimensional code.

  The log storage unit 180 stores a log of print data generated by the print data generation unit 160. In this embodiment, the “print data log” refers to a print data generation process history recorded in time series, and is stored together with date / time information indicating print data generation date / time. In addition, the log storage unit 180 stores the personal ID acquired by the personal information acquisition unit 150 in association with each print data. The log output unit 190 outputs the print data stored in the log storage unit 180 and log information that is a personal ID to the second external server 6 at a predetermined timing such as at the end of business or at the end of the month. The second external server 6 stores the log information in the log information database 61. The stored log information is used for fraud verification when a customer applies for a reduced tax rate refund.

  Next, a control method of the receipt printer 1 will be described with reference to the flowchart of FIG. The receipt printer 1 first acquires the personal ID by reading the customer's personal ID card with the card reader 2 when the customer comes in front of the checkout counter (S01). When a print command for printing the receipt R (see the receipt R0 in FIG. 4) is acquired from the POS terminal 3 (S02), the tax rate is determined for all purchased products included in the print command (S03).

  Based on the determination result of S03, if the purchased product does not include the reduced tax rate target product (S04: No), the print command acquired from the POS terminal 3 is used as it is (without editing) the print data for receipt printing. (S05). On the other hand, if the purchased product includes a reduced tax rate target product (S04: Yes), the standard tax rate is applied based on the price (tax excluded price) of all purchased products included in the print command acquired from the POS terminal 3 The difference between the case and the case where the reduced tax rate is applied is calculated (S06). Further, the print command is edited to generate print data (S07). Specifically, “*” is added to the product name (see reference numeral 91 in FIG. 5), difference information based on the calculation result of S06 is added (see reference numeral 92 in FIG. 5), and personal information is added (see FIG. 5). 5 (see reference numeral 93 in FIG. 5).

  After S05 and S07, the generated print data is printed on receipt paper, and a receipt R (receipt R0 in FIG. 4 or receipt R1 in FIG. 5) is issued (S08). Further, log information including the print data generated in S05 and S07 and the personal ID acquired in S01 is recorded in the log storage unit 180 (ROM 73) (S09), and a series of processing relating to the receipt R is completed. To do.

  In the above flowchart, the print command is acquired after acquiring the personal ID, but the order is not limited. Moreover, although log information was recorded after issuing the receipt R, the order is not ask | required. In addition, after acquiring the print command, the tax rate is determined for all purchased products. However, the tax rate is determined each time a print command for one line indicating the product name + price is acquired, not after acquiring the entire print command. May be performed. In this case, if the purchased product included in the print command for one line is a product subject to the reduced tax rate, “*” is added and printed one line at a time. If a product is included, the difference information and personal information may be added and printed.

  As described above, the receipt printer 1 of the first embodiment obtains a print command for printing the receipt R0 (see FIG. 4) from the POS terminal 3 that performs the accounting process, and edits this to edit the tax system. Print data for printing the combined receipt R1 (see FIG. 5) is generated. As described above, even when the tax system is revised, it is not necessary to update the POS system 10, so that the cost burden and business burden on the retailer can be reduced.

  Moreover, in this embodiment, since personal information is printed on the receipt R1, it can be used when the customer receives a refund of the reduced tax rate by submitting the receipt R in a final tax return or the like. Further, since the difference information is printed on the receipt R1, the customer can grasp the amount to be refunded. In the present embodiment, since log information in which print data and personal ID are associated is stored and output to the second external server 6, the tax office or the like uses the log information for illegal verification of a reduced tax rate refund application. be able to. Further, when the customer does not submit the receipt R to the tax office or the like, the reduced tax rate can be refunded to the individual specified by the personal ID based on the log information.

  In the present embodiment, since the tax rate is determined with reference to the tax rate database 51 provided by the National Tax Agency or the like, the retailer can reduce labor and cost for constructing and updating the tax rate database 51.

Note that the following modifications can be employed regardless of the above-described embodiment.
[Modification 1]
The print data generation unit 160 of the above embodiment adds a predetermined mark (“*”) to the product name subject to the reduced tax rate as editing product information (see FIG. 5). (The price) may be listed. FIG. 7 is a diagram illustrating a print example of the receipt R2 according to the present modification. In the figure, reference numeral 94 indicates an area listing reduced tax rate target products, and reference numeral 95 indicates an area listing standard tax rate target products. Also in this modification, difference information (see reference numeral 96) and personal information (see reference numeral 93) are included in the print data. However, in this modification, compared with the receipt R1 shown in FIG. 5, the total amount before tax of the reduced tax rate target product is omitted from the difference information. In this way, by listing the product name and its price by tax rate, it is possible to clearly show the tax type of each purchased product to the customer.

[Modification 2]
In the above embodiment and Modification 1, the product information is edited as the editing of the print command. However, the amount information may be edited. The amount information refers to the amount charged (total) based on the accounting processing result by the accounting processing unit 310, and the consumption tax or subtotal amount (subtotal) for calculating the amount charged. FIG. 8 is a diagram illustrating a print example of the receipt R3 according to the present modification. In this modified example, it is assumed that the reduced tax rate is not refunded by a transfer from the tax office or the like, but the store receives an amount obtained by subtracting the reduced tax amount for the reduced tax rate. In this case, as shown in the figure, the subtotal, consumption tax (8%), and total for the reduced tax rate target product (see reference number 97) are listed below the region where the reduced tax rate target product is listed (see reference number 94). And an area (see reference numeral 98) indicating the subtotal, consumption tax (10%), and total for the standard tax rate object commodity is provided below the area in which the standard tax rate object commodity is listed (see reference numeral 95). In addition, an area (see reference numeral 99) indicating the amount charged (total) is provided at the bottom of the receipt R3. The billing amount is the sum of the total for the reduced tax rate target product and the total for the standard tax rate target product. Thus, according to this modification, since the amount information included in the print command is edited, it is possible to cope with the receipt of the amount obtained by subtracting the reduced amount of the reduced tax rate at the store.

[Modification 3]
Although the receipt issuing system SY of the above embodiment includes the first external server 5 and the second external server 6, these may be omitted. FIG. 9 is a block diagram showing a functional configuration of the POS terminal 3 and the receipt printer 100 according to this modification. The receipt printer 100 according to the present modification has a configuration in which the communication unit 130 is omitted and a database storage unit 210 and a log writing unit 220 are added, compared to the functional configuration of the receipt printer 1 of the above-described embodiment (see FIG. 3). is there. In this modification, the print command acquisition unit 110, the tax rate determination unit 120, the difference calculation unit 140, the personal information acquisition unit 150, the print data generation unit 160, and the log writing unit 220 correspond to the control unit 200.

  The database storage unit 210 stores a tax rate database (corresponding to the tax rate database 51 in the above embodiment) indicating the tax rate of the product. The log writing unit 220 writes the log information stored in the log storage unit 180 to the external storage medium M at a predetermined timing such as when print data is generated or when the receipt printer 100 is powered off. The external storage medium M may be used as a backup for the log storage unit 180 or may be used as a submission to a tax office or the like. Thus, according to this modification, since it is not necessary to provide the communication means in the receipt printer 100, the apparatus configuration can be simplified.

[Modification 4]
The tax rate determination unit 120 of the above embodiment determines the tax rate based on the reference result of the tax rate database 51. If the product information includes specific information, the tax rate of the purchased product specified by the product information is specified. You may determine with the specific tax rate corresponding to information. For example, in other countries, taxation methods are known in which the same product has a standard tax rate for in-store dining and a reduced tax rate for out-of-store dining (takeout).
