Description

The present invention relates to a sales data processing device , a sales data processing method, and a program.

  The 2015 Tax Reform Law was passed by the Upper House Plenary Meeting on March 31, 2015, and passed. According to this law, the consumption tax rate will be raised to 10% in April 2017. As a measure against low-income earners following the 10% increase in the consumption tax rate, a reduced tax rate system will also be introduced.

  The reduced tax rate system introduced this time will leave the consumption tax rate at 8% for some products that have a significant impact on low-income earners. The items subject to the reduced tax rate system are the transfer of food and beverages and the subscription fee for newspapers issued at least twice a week. However, of the transfer of food and beverages, the provision of meals provided by businesses operating restaurants and the like at places with certain eating and drinking facilities is excluded from items subject to the reduced tax rate system. In other words, the standard tax rate is applied to the transfer of food and beverage that corresponds to eating out.

  More specifically, examples of reduced tax rates that apply to eating out include eating out at a gyudon restaurant or hamburger shop, visiting a soba shop, delivering a pizza place, snacking at a stall, selling sushi or souvenirs, Listed convenience store lunches and prepared dishes. In addition, examples of the standard tax rate applied to eating out are provided on the assumption that eating and drinking at beef bowl restaurants, hamburger stores, soba restaurants, pizzerias and sushi restaurants, snacks at food courts, and eating at convenience store eat-in corners. Food and drinks, catering and business trips are listed.

  Meals provided under the reduced tax rate system are classified as eating out if they are provided by a business operator such as a restaurant business under the Food Sanitation Law where facilities for eating and drinking are installed on the spot. In addition, cooking at a place designated according to the order of the other party is also classified as eating out here.

  An invention corresponding to such a plurality of tax rates includes, for example, an invention described in Patent Document 1. The solution to the abstract of Patent Document 1 includes "In ECR1, for a pack product including a plurality of taxable products, one product registration process is performed according to a tax amount calculation method previously set in the TAX table setting memory 54. The tax amount of each taxable product was calculated, and the taxable amount of each taxable product could be printed on the receipt. "

JP 2003-256937 A

However, in the invention described in Patent Document 1, the difference from the standard tax rate under the reduced tax rate system has to be calculated by the client by mental arithmetic or the like.
For example, when an item with a standard tax rate is registered as a tax-inclusive price of 2,200 yen and an item with a reduced tax rate is registered as a tax-inclusive price of 2,160 yen, the difference from the standard tax rate by the reduced tax rate system is 40 yen. However, this could not be read directly from the receipt or the display on the display. Therefore, each customer could not easily realize the benefits of the reduced tax rate system.
Therefore, an object of the present invention is to enable a customer of a store to easily realize the merits of the reduced tax rate system for a sales data processing device , a sales data processing method, and a program.

In order to achieve the above object, a sales data processing apparatus according to the present invention includes a receiving unit for receiving sales registration of a product or service, and a tax when a reduced tax rate is applied to the product or service for which the sales registration is received. Derivation means for deriving the difference between the amount or the tax-included price and the tax amount or the tax-included price when the standard tax rate is applied, and each time the sales registration is received, the tax amount or the tax-included price of the accepted product or service , and the difference, characterized by Rukoto and an output means for outputting to the display unit for guest with application condition of the rate that is adapted to the goods or services received.
In addition, sales data processing method according to the present invention, the tax amount or a tax-inclusive price of the case and the acceptance step of accepting the sales registration of goods or services, the reduced tax rate for goods or services accepted the sales registration is applied And a derivation step of deriving a difference between the tax amount or the tax-included price when the standard tax rate is applied, and each time the sales registration is received, the tax amount or the tax-included price of the received product or service, and the difference Output to the customer display unit together with the applicable conditions of the tax rate adapted to the received product or service .
Also, when engaged Help program to the present invention, the computer used in the sales data processing apparatus, receiving means for receiving a sales registration of goods or services, reduced rate is applied to the goods or services is accepted the sales registration Derivation means for deriving the difference between the tax amount or tax-included price and the tax amount or tax-included price when the standard tax rate is applied, every time the sales registration is received, the tax amount of the received product or service or the tax-included It is characterized by functioning as an output means for outputting the price and the difference together with the applicable condition of the tax rate adapted to the received product or service to the customer display unit .

FIG. 1B is an external view of the housing when viewed from diagonally rearward.
On the rear side of the housing of the electronic cash register 1, a customer display unit 15 is provided. When the store customer faces the store clerk directly through the electronic cash register 1, the customer display unit 15 can be easily visually recognized.
The operator of the electronic cash register 1 can register a product by inputting a unit price and a department of the product via the input unit 18, displaying a subtotal, and then inputting a deposit. At the time of registering this product, the electronic cash register 1 pulls out the drawer 17 and deposits the deposit.

FIG. 2 is a block diagram showing a configuration of the electronic cash register 1.
2, the electronic cash register 1 includes a CPU (Central Processing Unit) 11, a RAM (Random Access Memory) 12, a ROM (Read Only Memory) 13, a display unit 14, a customer display unit 15, a printing unit 16, and a drawer 17. , An input unit 18 and a storage unit 19, and each unit is connected by a bus.

  The CPU 11 stores application programs specified from various application programs corresponding to the electronic cash register 1 stored in the ROM 13 or the storage unit 19 and various instructions input from the input unit 18 in the work memory in the RAM 12. expand. The CPU 11 further executes various processes according to the application program developed in the work memory in accordance with the input instruction and the input data, stores the processing results in the work memory in the RAM 12, and displays the display unit 14 and the customer display unit 15. To be displayed. Then, the CPU 11 stores the processing result stored in the work memory in a storage destination in the storage unit 19 specified by the input unit 18.

  Further, the CPU 11 analyzes the instruction content input from the input unit 18 in a product registration process described later (see FIG. 5), and if the instruction content is any of the department codes, the department stored in the storage unit 19. The table 191 is searched, a product of the corresponding section is registered, and a tax amount of the product is calculated. Then, in the overall processing, the CPU 11 analyzes the instruction content input from the input unit 18, and executes the closing process when the instruction content is closing, or executes a process according to another instruction content.

The input unit 18 includes a keyboard provided with various function keys including a department key, a current / deposit key, a clear key, and the like, and a numeric input key, and outputs a pressing signal pressed by the keyboard to the CPU 11. The input unit 18 functions as a receiving unit that receives sales registration of a product or service. The configuration of the input unit 18 will be described later in detail with reference to FIG.
The input unit 18 is not limited to a keyboard, but may be any unit that can input an instruction. For example, the input unit 18 senses coordinates specified by an input pen, a fingertip, or the like like a touch panel (touch screen), and calculates position coordinates specified by a coordinate reading principle such as an electromagnetic induction method, a magnetostrictive method, or a pressure-sensitive method. You may make it detect. In this case, the input unit 18 outputs the detected position coordinates to the CPU 11 as a position signal.

The display unit 14 and the customer display unit 15 are configured by a liquid crystal display or an organic EL display or the like, and correspond to kanji, hiragana, and katakana displays. The electronic cash register 1 generates a signal based on display data input from the CPU 11 and performs various displays on the display unit 14 and the customer display unit 15.
The printing unit 16 is, for example, a thermal transfer printer, and prints and outputs receipt information on roll paper (receipt paper). The printing unit 16, based on the price and the tax rate of the product or service, in accordance with the instruction of the CPU 11, determines the tax amount of the applied product or the applied service of the reduced tax rate and the case where the standard tax rate is applied to the applied product or the applied service. The difference from the tax amount is output on the receipt.
The drawer 17 is a portion for storing cash, and can be withdrawn by an operator operating the electronic cash register 1.

The storage unit 19 is configured by a rewritable storage medium such as a magnetic or optical storage medium or a semiconductor memory. The storage unit 19 stores, in addition to the department table 191 and the PLU (Price Look Up) file 192, a system program, various application programs corresponding to the system, data processed by these programs, and the like. The section table 191 will be described later in detail with reference to FIG. The PLU file 192 will be described in detail later with reference to FIG.
The CPU 11 refers to the section table 191 and the PLU file 192 to derive a tax amount or a tax-included price based on a predetermined tax rate for the goods or services for which sales registration has been accepted, and displays the derived tax amount or tax-included price. It functions as an output unit that outputs to the unit 14, the customer display unit 15, and the printing unit 16.

  The program, data, and the like stored in the storage unit 19 may be partially or entirely received from another device such as a server or a client via a transmission medium such as a network line and stored. Further, the storage unit 19 may be a recording medium of a server constructed on a network. Furthermore, each program may be configured to be transmitted to a server or a client via a transmission medium such as a network line and installed on these devices.

FIG. 3 is a diagram illustrating the department table 191.
The section table 191 includes a section code section, a section name section, a calculation method section, and a tax rate section. This indicates the correspondence between each section key and the tax calculation method.
Section 1 is a section for inputting the amount of the internal tax method for an item to which a standard tax rate of 10% is applied. Here, the internal tax method refers to a method of selling a product whose consumption amount includes a consumption tax. When the user selects the department 1 key, "department 01" in the department name column is displayed on the display unit 14, and the tax amount and the "tax included" in the calculation method column and the tax rate of 10% described in the tax rate column are displayed. Tax-included price is calculated.
Section 2 is a section for inputting the amount of the tax-inclusive method for an item to which the 8% reduced tax rate is applied. When the user selects the department 2 key, "department 02" in the department name column is displayed on the display unit 14, and the tax amount and the "tax included" in the calculation method column and the tax rate of 8% described in the tax rate column are displayed. Tax-included price is calculated.
The section 3 is a section for inputting the amount of the external tax method for an item to which the standard tax rate of 10% is applied. Here, the external tax method refers to a method of selling a product whose consumption amount does not include a consumption tax. When the user selects the department 3 key, “department 03” in the department name column is displayed on the display unit 14, and the tax amount and the “external tax” described in the calculation method column and the tax rate of 10% described in the tax rate column are displayed. Tax-included price is calculated.
The section 4 is a section for inputting the amount of the external tax method for an item to which the 8% reduced tax rate is applied. When the user selects the department 4 key, “department 04” in the department name column is displayed on the display unit 14, and the tax amount and the tax rate are set at “external tax” in the calculation method column and 8% in the tax rate column. Tax-included price is calculated.

FIG. 4 is a diagram illustrating the PLU file 192.
The PLU file 192 includes a PLU number column, a product name column, a unit price column, a calculation method column, and a tax rate column. Thereby, the correspondence between the PLU number and the product / unit price / calculation method / tax rate can be indicated.
The PLU number column stores a product code related to the product. The product name column stores the product name of the product. The unit price column stores the unit price in the method of calculating the tax applied to the product. In the calculation method column, a calculation method of a tax amount applied to the product is stored. For example, when “tax included (standard tax rate)” or “tax included (reduced tax rate)” is stored in the calculation method column, the unit price column stores the unit price including tax. When “external tax (standard tax rate)” or “external tax (reduced tax rate)” is stored in the calculation method column, the unit price excluding tax is stored in the unit price column. The tax rate column stores a tax rate corresponding to the product in percent.

FIG. 5 is a diagram illustrating a configuration of the input unit 18 of the electronic cash register 1.
The input unit 18 includes a group of keys arranged in a matrix of 7 rows and 6 columns, and these key groups are roughly divided into four. Keys used for merchandise registration are mainly arranged in a lower left section and a lower right section. Here, the lower left section and the lower right section of the key group will be described, and the description of the upper left section and the upper right section will be partially omitted.

The “C” (clear) key belonging to the lower left section is used when the operator makes an error. The "x / date" key is used for multiplication registration and for displaying time and date. The "10,000 yen" key is used when depositing a 10,000 yen bill.
Numeric keys such as "9" to "0", "00", and "." Are used to input numerical values.

  The “Department 1” to “Department 5” keys belonging to the lower right section are used when the operator registers a product. The “subtotal” key is used to view the total (intermediate total) of the registered amounts. The "current / deposit" key is used when completing registration and deposit.

  In addition, the “payment” key is used at the time of payment. The “payout” key is used at the time of withdrawal and also at the time of issuing an electronic journal report. The "-" key is used at the time of discount, and the "%" key is used at the time of discount. The “shin” (credit selling) key is used when selling a credit card, and the “ticket” (ticket selling) key is used when selling a gift certificate. The "# / replacement" key is used at the time of number printing or exchange. The “PLU” key is used when specifying a product by a PLU number.

FIG. 6 is a flowchart showing the product registration process.
The CPU 11 of the electronic cash register 1 repeats the processing of steps S10 to S23 for each transaction with the customer. Display examples of the display unit 14 and the customer display unit 15 at this time are shown in FIGS. 7 and 8 described later. Each time the operator registers a product, the CPU 11 repeats the processing of steps S10 to S17.
The CPU 11 determines which key of the input unit 18 has been input (step S10).

In step S10, if the numeric key of the input unit 18 is pressed, the CPU 11 updates the numbers on the display unit 14 and the customer display unit 15 (step S11), and returns to the process of step S10.
If the "x" key is pressed in step S10, the CPU 11 proceeds to step S12 in which the numbers on the display unit 14 and the customer display unit 15 are determined as the product quantity, and returns to the process in step S10. Specifically, when the operator inputs the product quantity, the operator may press the “×” key after inputting the product quantity with the numeric keys.

If the "department 1" key is pressed in step S10, the CPU 11 proceeds to step S13 where the numbers on the display unit 14 and the customer display unit 15 are determined as the standard tax rate and the internal tax system, and the "department 2" key Is pressed, the process proceeds to step S14 in which the numbers on the display unit 14 and the customer display unit 15 are determined as the reduced tax rate and the internal tax system, and the process returns to step S10.
More specifically, when the operator presses the "Department 1" key after inputting the product price with the numeric keys, the price of the product with the standard tax rate is input in the internal tax system. When the operator presses the "Department 2" key after inputting the product price with the numeric keys, the price of the product with the reduced tax rate is input by the internal tax method.

In step S10, if the "Department 3" key is pressed, the CPU 11 determines the numbers on the display unit 14 and the customer display unit 15 as the standard tax rate and the foreign tax system (Step S15), Is pressed, the numbers on the display unit 14 and the customer display unit 15 are determined as the reduced tax rate and the foreign tax method (step S16), and the process returns to step S10.
Specifically, when the operator inputs the price of the product with the standard tax rate by the foreign tax method, it is preferable to input the product price with the numeric keys and then press the “section 3” key. Further, when the operator inputs the price of the product with the reduced tax rate by the external tax method, it is preferable to input the product price with the numeric keys and then press the “section 4” key.
If the "PLU" key is pressed in step S10, the CPU 11 proceeds to step S17 to determine a product, a unit price, a tax rate, and a calculation method using the numbers on the display unit 14 and the customer display unit 15 as PLU numbers, After that, the process returns to step S10. More specifically, when the operator designates a product by a PLU number, the operator may press a “PLU” key after inputting the PLU number with a numeric key.

If the "subtotal" key is pressed in step S10, CPU 11 calculates the subtotal and the difference (step S18). Here, the difference is the difference between the standard tax amount and the reduced tax amount. That is, if the product or service whose sales registration has been accepted is a product to which the reduced tax rate (first tax rate) is applied, the CPU 11 determines the tax amount or the tax amount when the reduced tax rate is applied to this product or service. The difference between the tax-included price and the tax amount or the tax-included price when the standard tax rate (second tax rate) is applied to this product or service is derived. That is, if the product for which the sales registration has been accepted is a product to which the reduced tax rate (first tax rate) is applied, the CPU 11 determines a tax amount when the reduced tax rate is applied to this product and a standard amount for this product. The difference from the tax amount when the tax rate (second tax rate) is applied is derived, and the derived difference is output to the display unit 14 and the customer display unit 15.
While alternately displaying the subtotal and the difference on the display unit 14 and the customer display unit 15 (step S19), the CPU 11 determines which key of the input unit 18 has been input (step S20). When the numeric key is pressed, the CPU 11 updates the numbers on the display unit 14 and the customer display unit 15 (step S21), and returns to the process of step S20.
In step S20, if the "current / deposit" key is pressed, the CPU 11 calculates and displays the change (step S22), causes the printing unit 16 to print a receipt (step S23), and executes the processing in FIG. finish. Examples of receipt printing at this time are shown in FIGS. 8, 9 and 11 described later.

FIGS. 7A to 7E are diagrams showing display examples of accounting in the tax-inclusive method. In the display examples of FIGS. 7A to 7E, the operator inputs the item of 2200 yen to which the standard tax rate is applied and the item of 1080 yen to which the reduced tax rate is applied, and displays the subtotal. This is an example when a deposit of 4000 yen is received later.

FIGS. 14A and 14B are external views of the electronic cash register 3 according to the second embodiment. The electronic cash register 3 is a compact type for small and medium-sized stores, and can be operated by a touch panel display.
FIG. 14A is an external view when viewed from diagonally forward of the housing.
The electronic cash register 3 is provided with a touch panel display 34 serving as an input unit and a display unit, a customer display unit 35 (on a hidden surface) provided on the rear side of the housing, and provided on the left side of the housing. The printing unit 36 is included. The drawer is disposed separately from the housing of the electronic cash register 3.

FIG. 14B is an external view of the housing when viewed from diagonally rearward.
On the rear side of the housing of the electronic cash register 3, a customer display unit 35 is provided. When the store customer faces the store clerk via the electronic cash register 3, the customer display unit 35 can be easily visually recognized.
The operator of the electronic cash register 3 inputs the number of products and PLU (Price Look Up) through the touch panel display 34, displays a subtotal, and then inputs a deposit, thereby registering the products. it can. When registering this product, the electronic cash register 3 pulls out a drawer (not shown) and deposits a deposit. Note that the registration of the product is not limited to the input of the PLU, and the bar code reader may be used to read the product information, or a button corresponding to each product may be displayed on the touch panel display 34.

FIG. 15 is a block diagram showing a configuration of the electronic cash register 3. As shown in FIG.
In FIG. 15, the electronic cash register 3 includes a CPU 31, a RAM 32, a ROM 33, a touch panel display 34, a customer display unit 35, a printing unit 36, an external interface 37, an input unit 38, and a storage unit 39. Connected by

  The CPU 31 stores, in the RAM 32, an application program specified from various application programs corresponding to the electronic cash register 3 stored in the ROM 33 or the storage unit 39 and various instructions input from the touch panel display 34 or the input unit 38. To work memory. The CPU 31 further executes various processes in accordance with the application program expanded in the work memory in accordance with the input instruction and the input data, stores the processing results in the work memory in the RAM 32, and displays the touch panel display 34 and the customer display 35 To be displayed. Then, the processing result stored in the work memory is stored in a storage destination in the storage unit 19 specified by the touch panel display 34 or the input unit 38.

  Further, in the product registration processing (see FIG. 17) described later, the CPU 31 analyzes the instruction content input from the touch panel display 34, and if the instruction content is designated by the PLU, the PLU file 391 stored in the storage unit 19 Is registered, and the product related to the corresponding PLU is registered, and the tax amount and the like of this product are calculated. Then, in the overall process, the CPU 31 analyzes the instruction content input from the touch panel display 34, and executes the closing process when the instruction content is the closing, or executes a process according to another instruction content.

The input unit 38 is, for example, a power switch, a reset switch, or the like, and outputs a press signal indicating that these switches have been pressed to the CPU 31.
The touch panel display 34 is formed by laminating a transparent touch panel on a surface of a display device such as a liquid crystal display, and has both a display function and an input function. The touch panel (touch screen) senses coordinates specified by an input pen, a fingertip, or the like, detects position coordinates specified by a coordinate reading principle such as an electromagnetic induction method, a magnetostriction method, or a pressure-sensitive method, and outputs the position coordinates to the CPU 31. I do. The CPU 31 displays various keys and the like on a display device constituting the touch panel display 34, and detects that the display area of these keys has been tapped on the touch panel. Thus, the CPU 31 implements functions such as a numeric key, a “PLU” key, and a “subtotal” key, and accepts sales registration of a product or service. Further, the CPU 31 derives a tax amount or a tax-included price based on a predetermined tax rate for the goods or services whose sales registration has been accepted, and outputs the tax amount or the tax-included price on the touch panel display 34.
The “x” key embodied on the touch panel display 34 is used for multiplication registration and for displaying time and date. Numeric keys such as "9" to "0", "00", and "." Are used to input numerical values. The “subtotal” key is used to view the total (intermediate total) of the registered amounts. The "current / deposit" key is used when completing registration and deposit. The “PLU” key is used when a product is designated by a PLU number.

The customer display unit 35 is configured by a liquid crystal display, an organic EL display, or the like, and supports kanji, hiragana, and katakana displays. The CPU 31 derives a tax amount or a tax-included price based on a predetermined tax rate for the goods or services whose sales registration has been accepted, and outputs the tax amount or the tax-included price on the customer display unit 35.
The printing unit 36 is, for example, a thermal transfer printer, and prints and outputs receipt information on roll paper (receipt paper). The printing unit 36, based on the price and tax rate of the product or service, in accordance with the instruction of the CPU 31, determines the tax amount of the product or service to which the reduced tax rate is applied and the tax amount when the standard tax rate is applied to the applicable product or service. The difference from the tax amount is output on the receipt.
The external interface 37 is for connecting a drawer 41, a barcode scanner 42, and the like, for example.
The drawer 41 is a portion for storing cash, and can be withdrawn by an operator operating the electronic cash register 3. The barcode scanner 42 is a part that reads a barcode of a product by an operation of an operator.

The storage unit 39 is configured by a rewritable storage medium such as a magnetic or optical storage medium or a semiconductor memory. The storage unit 39 stores, in addition to the PLU file 391, a system program, various application programs corresponding to the system, data processed by these programs, and the like. The PLU file 391 will be described later in detail with reference to FIG.
The CPU 31 determines which of the reduced tax rate and the standard tax rate is applied to each product or service with reference to the PLU file 391.

  The program, data, and the like stored in the storage unit 39 may be partially or wholly received from another device such as a server or a client via a transmission medium such as a network line and stored. Further, the storage unit 39 may be a recording medium of a server constructed on a network. Furthermore, each program may be configured to be transmitted to a server or a client via a transmission medium such as a network line and installed on these devices.

FIG. 16 is a diagram illustrating the PLU file 391.
The PLU file 391 includes a PLU number column, a product name column, a unit price column, a calculation method column, and a tax rate column, similarly to the PLU file 192 of the first embodiment (see FIG. 4). Thereby, the correspondence between the PLU number and the product / unit price / calculation method / tax rate can be indicated.
The PLU number column stores a product code related to the product. The product name column stores the product name of the product. The unit price column stores the unit price in the method of calculating the tax applied to the product. In the calculation method column, a calculation method of a tax amount applied to the product is stored. For example, when “tax included (standard tax rate)” or “tax included (reduced tax rate)” is stored in the calculation method column, the unit price column stores the unit price including tax. When “external tax (standard tax rate)” or “external tax (reduced tax rate)” is stored in the calculation method column, the unit price excluding tax is stored in the unit price column. The tax rate column stores a tax rate corresponding to the product in percent.

FIG. 17 is a flowchart showing the product registration process.
The CPU 31 of the electronic cash register 3 repeats the processing of steps S30 to S39 for each transaction with the customer. Each time the operator registers a product, the CPU 31 repeats the processing of steps S30 to S33.
CPU 31 determines which of the keys displayed on touch panel display 34 has been input (step S30).

In step S30, if a numeric key on touch panel display 34 is tapped, CPU 31 updates the numbers on touch panel display 34 and customer display unit 35 (step S31), and returns to the process of step S30.
If the "x" key on the touch panel display 34 is tapped in step S30, the CPU 11 proceeds to step S32 in which the numbers on the touch panel display 34 and the customer display unit 35 are determined as the product quantity, and proceeds to step S30. Return. Specifically, when the operator inputs the product quantity, the operator may tap the numeric keys on the touch panel display 34 to input the product quantity, and then tap the “x” key.

  If the "PLU" key on the touch panel display 34 is tapped in step S30, the CPU 31 determines a product, a unit price and a tax rate using the numbers on the touch panel display 34 and the customer display unit 35 as PLU numbers (step S33). Then, the process returns to step S30. Specifically, when the operator designates a product by a PLU number, it is preferable to input a PLU number using numeric keys on the touch panel display 34 and then tap the “PLU” key.

  If the "subtotal" key on touch panel display 34 is tapped in step S30, CPU 31 calculates the subtotal and the difference (step S34). Here, the difference is the difference between the standard tax amount and the reduced tax amount. The CPU 31 displays the subtotal and the difference on the touch panel display 34 and the customer display unit 15 (step S35). That is, if the product for which the sales registration has been accepted is a product to which the reduced tax rate (first tax rate) is applied, the CPU 31 determines the tax amount when the reduced tax rate is applied to this product and the standard amount for this product. The difference from the tax amount when the tax rate (second tax rate) is applied is derived, and the derived difference is output to the touch panel display 34 or the customer display unit 35.

Further, if the product whose sales registration has been accepted is a product to which the reduced tax rate (first tax rate) is applied, the CPU 31 outputs this difference as reduction information, and the product whose sales registration has been accepted has the standard tax rate ( If the product is a product to which the second tax rate is applied, the difference is output to the touch panel display 34 or the customer display unit 15 as increase information.
If the numeric key on the touch panel display 34 is tapped (step S36), the CPU 11 updates the numbers on the touch panel display 34 and the customer display unit 15 (step S37), and returns to the process of step S36.
In step S36, if the "current / deposit" key on the touch panel display 34 is tapped, the CPU 11 calculates and displays the change (step S38), and causes the printing unit 36 to print a receipt (step S39). The processing in FIG. 17 ends.
