Description

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

Conventionally, a compact electronic cash register (ECR; Electronic Cash Register) or a high-performance POS (POS) has been installed as a sales data processing device installed in a store or the like that sells products (including services) and accepts the designation of product sales registration. An electronic device such as a terminal device is known.
When the sales data processing device receives an instruction to execute an accounting process at the time of selling a product, the sales data processing device calculates the accounting amount and the consumption tax of the product for which the designation of sales registration has been received, and executes the accounting process for the product.

On the other hand, in Japan in April 2017, multiple consumption tax rates will be enforced. When the consumption tax with multiple tax rates is enforced, the standard tax rate (10%) may be applied to the consumption tax accounting, or the reduced tax rate may be lower than the standard tax rate, depending on the type of goods (including services). (8%) would be applied to the accounting for consumption tax.
As such a sales data processing device for dealing with a plurality of tax rates, a tax amount as a product obtained by combining a plurality of products is calculated from a tax amount of each of a plurality of products, and a receipt after sales is calculated. Patent Document 1 discloses an apparatus for printing a tax amount for each product.

JP 2003-256937 A

When a consumption tax with a plurality of tax rates is enforced, the conventional technology described in Patent Document 1 has the following problems.
In the related art, the standard tax rate is applied to the accounting for the consumption tax, or a reduced tax rate lower than the standard tax rate is applied to the accounting for the consumption tax, depending on the type of the product (including the service). This reduced tax rate may be applied to the consumption tax accounting process or the reduced tax rate may be applied to the consumption tax accounting for the same product, depending on the type of transaction (for example, in-store dining and take-out transactions). Or applied to processing.
That is, according to the conventional technology, even if a plurality of products have different tax rates, the products are sold by collectively subtotaling.

However, for example, if the product purchased by the customer after recognizing the product as the target of the reduced tax rate is actually a product with the standard tax rate, the customer will erroneously purchase the product with the standard tax rate.
In this case, the customer needs to recognize the error by a receipt or the like after the completion of the accounting process or at home, and need to perform the accounting process for canceling the purchase of the product again or visit the store again.
Further, if the purchase amount is not confirmed by a receipt or the like, the customer purchases the product without noticing the error.

  An object of the present invention is to enable a customer to cancel the purchase of a product at an unintended tax rate before performing the accounting process on the product.

In order to solve the above problem, a sales data processing device according to the present invention includes a display control unit configured to display a list of products for which a registration of sales has been received in one transaction according to a tax rate applied to the products, and First designation means for collectively designating, for each tax rate applied to the commodity, a commodity for which the designation of the sales registration is to be canceled from the list of commodities displayed separately by the control means. And
Further, the program according to the present invention is a display control means for causing the computer of the sales data processing apparatus to display a list of products for which the designation of sales registration has been received in one transaction, classified according to a tax rate applied to the products, and the display control. Means for functioning as a first designating means for collectively designating, for each of the tax rates applied to the product, a product for which the designation of the sales registration is to be canceled from the list of the products displayed separately by means. .

  According to the present invention, it is possible to cancel the purchase of a product at a tax rate not intended by the customer before performing the accounting process on the product.

The cancel accepting screens 40 and 50 may be displayed by separately selecting the "cancel" key 36 in addition to the "subtotal" key 35a.
The “cash” key 35b is an area instructed when purchasing a product with cash. When the “cash” key 35 b is selected, the commodity registration means 20 outputs an instruction to open the cash storage unit to the drawer 15.
Returning to FIG. 3, the description of the configuration of the control program will be continued.

The cancellation processing unit 21 performs a cancellation process of the product registered by the product registration unit 20. The cancel processing unit 21 operates when the product registration in the product registration unit 20 is completed and the “subtotal” key 35a (see FIG. 4) is selected. Alternatively, the cancel processing means 21 operates when the “cancel” key 36 (see FIG. 4) is selected.
As shown in FIG. 3, the cancellation processing unit 21 includes a tax rate classified display unit 211, a batch designation unit 212, and an individual designation unit 213.

The tax rate classification display means (display control means) 211 classifies a list of products for which registration of sales has been received in one transaction by a tax rate applied to the product, and receives a cancellation of the product (cancel reception screen 40, 50 (see FIGS. 5 and 6)). The tax rate-separated display means 211 refers to the product database DB (see FIG. 10) and displays the cancellation reception screens 40 and 50 in which the list of the products registered by the product registration means 20 is classified according to the tax rate. And the customer display device 122, respectively.
When displaying the cancellation reception screen 50 on the display device 112 for the clerk, the tax rate classified display unit 211 switches the sales registration screen 30 (see FIG. 4) to the cancellation reception screen 50 or displays the sales registration screen 30 on the sales registration screen 30. The cancel acceptance screen 50 is superimposed.

Here, an example of the cancel acceptance screen 40 displayed on the customer display device 122 by the tax rate classified display means 211 will be described with reference to FIG.
As shown in FIG. 5, the cancellation reception screen 40 includes a first tax rate product list 41 that is a list (product name and amount) of products having a first tax rate (here, a reduced tax rate of 8%) and a second tax rate (here). In this case, a second tax rate product list 42 which is a list of products (product name and price) with a standard tax rate of 10% is displayed.

  Specifically, the tax rate classified display unit 211 refers to the product database DB (see FIG. 10) stored in the storage device 103 and refers to the tax rate corresponding to the product code of the product registered by the product registration unit 20. Displays a product name and a unit price (amount) as a first tax rate product list 41 for a product having a first tax rate (here, a reduced tax rate of 8%). In addition, the tax rate classified display unit 211 displays the product name and unit price (amount) of the product whose tax rate corresponding to the product code of the product registered by the product registration unit 20 is the second tax rate (here, the standard tax rate is 10%). Are displayed as the second tax rate product list 42.

Here, the tax rate-separated display means 211 displays collective designation check boxes (first check boxes) 43 and 44 for instructing to collectively cancel the product list for each tax rate on the cancel reception screen 40. . In addition, the tax rate classified display unit 211 displays a plurality of individual designation check boxes (second check boxes) for individually canceling products for each tax rate in the first tax rate product list 41 and the second tax rate product list 42. ) 45 and 46 are displayed.
When the first tax rate product list 41 and the second tax rate product list 42 have registered more products than the maximum display number of each list, the tax rate classified display unit 211 displays a scroll bar on each list. To enable scroll display in the list.

The collective designation check box 43 is an area for designating that products with a reduced tax rate (8%) are collectively canceled. The tax rate classified display means 211 displays the batch designation check box 43 at a position closer to the first tax rate product list 41 than to the second tax rate product list 42. The collective designation check box 43 is preferably displayed on an extension of the first tax rate product list 41 on which the plurality of individual designation check boxes 45 are arranged.
Thus, it is possible to prevent the customer from mistakenly recognizing the collective designation check box 43 as a collective cancellation check box for the standard tax rate.

The collective designation check box 44 is an area for designating that products with the standard tax rate (10%) are collectively canceled. The tax rate classified display unit 211 displays the batch designation check box 44 at a position closer to the second tax rate product list 42 than to the first tax rate product list 41. This collective designation check box 44 is preferably displayed on an extension of the second tax rate product list 42 in which a plurality of individual designation check boxes 46 are arranged.
Thus, it is possible to prevent the customer from erroneously recognizing the collective designation check box 44 as a collective cancellation check box for the reduced tax rate.

  The individual designation check box 45 is an area for designating that products with reduced tax rates are individually canceled. The tax rate classified display unit 211 displays the individual designation check box 45 at a position closer to other products in correspondence with each product in the first tax rate product list 41. This can prevent the customer from erroneously canceling another product with a reduced tax rate.

The individual designation check box 46 is an area for designating that the products of the standard tax rate are individually canceled. The tax rate classified display unit 211 displays the individual designation check box 46 at a position closer to other products than the other products, corresponding to each product in the second tax rate product list 42. This can prevent a customer from accidentally canceling another product with a standard tax rate.
In addition, it is preferable that the tax rate classified display unit 211 displays, on the cancellation reception screen 40, the amount of each tax rate and the total amount when the cancellation is performed, as shown in FIG. Thereby, the customer can recognize the amount of money after the cancellation of the product.

Next, an example of the cancel reception screen 50 displayed on the display device 112 for the clerk by the tax rate classified display means 211 will be described with reference to FIG.
The cancellation reception screen 50 is a screen for the clerk to grasp the details of the cancellation performed by the customer on the cancellation reception screen 40 (see FIG. 5) and execute the cancellation.
Specifically, as shown in FIG. 6, the tax rate classified display unit 211 displays the same content as the cancellation reception screen 40 as the cancellation reception screen 50.
In addition, the tax rate classified display unit 211 further displays a “close” key 51 and a “fix” key 52 on the cancellation reception screen 50.

  The “close” key 51 is an area for instructing to close the cancel reception screen 50 and the cancel reception screen 40 (see FIG. 5) displayed on the customer display device 122 without canceling. This “close” key 51 is used when the customer does not cancel, or when the customer cancels, but the customer wants to cancel the cancellation at once, for example, when the customer does not cancel. Selected by the clerk.

The “confirm” key 52 is an area for instructing to confirm the details of the cancellation performed by the customer. The “confirm” key 52 is selected by the clerk after the clerk confirms the customer's agreement of the cancellation contents. As a result, the content of the actual cancellation is determined. When the “OK” key 52 is selected, the cancel accepting screen 50 and the cancel accepting screen 40 (see FIG. 5) displayed on the customer display device 122 are closed.
Returning to FIG. 3, the description of the configuration of the control program will be continued.

The tax rate classified display unit 211 controls the display of the cancel reception screens 40 and 50 illustrated in FIGS. 5 and 6.
At this time, the tax rate classified display unit 211 retains the state in which the check box is selected during the operation of the cancellation processing unit 21. Therefore, the tax rate classified display unit 211 displays a flag indicating the batch cancellation state by tax rate in the RAM 101 as an internal state. A batch designation flag) and a flag (individual designation flag) indicating an individual cancellation state for each product are prepared, and are reset in advance when the cancel acceptance screens 40 and 50 are displayed.
When the “close” key 51 or the “confirm” key 52 is selected, the tax rate classified display means 211 shifts to the operation of the accounting processing means 22.

The collective designation unit 212 processes designation of the collective designation check boxes 43 and 44 on the cancel acceptance screens 40 and 50.
The collective designation unit 212 selects the collective designation check boxes 43 and 44 on the cancel reception screens 40 and 50 via the customer input device 121 or the clerk input device 111 when the check boxes 43 and 44 are selected. Draw a check mark (check point) indicating that the operation has been performed.

When the collective specification check boxes 43 and 44 are selected, the collective specification means 212 draws check marks on all the individual specification check boxes 45 and 46 in the product list corresponding to the tax rate of the selected check box. It shall be. As a result, it is possible to more clearly indicate to the customer that all the products for the selected tax rate have been canceled.
For example, as shown in FIG. 7, when the collective designation check box 44 is selected, a check mark is drawn on the collective designation check box 44 and the second tax rate product list 42 of the standard tax rate corresponding to the collective designation check box 44 is displayed. A check mark is drawn in all the individual specification check boxes 46.

In addition, when the collective specification check boxes 43 and 44 on which the check marks are already drawn are selected, the collective specification unit 212 cancels the collective specification, deletes the check marks of the collective specification check boxes 43 and 44, and performs the selection. In the product list corresponding to the tax rate of the selected check box, all the check marks of the individual specification check boxes 45 and 46 are deleted.
When the collective specification check boxes 43 and 44 are selected, the collective specification means 212 sets flags (collective specification flags) corresponding to the respective tax rates in order to maintain the state. In addition, when the selection of the collective specification check boxes 43 and 44 is canceled, the collective specification unit 212 resets flags (collective specification flags) corresponding to the respective tax rates.

  When the collective specification means 212 selects or cancels the individual specification check boxes 45 and 46 by selecting or canceling the collective specification check boxes 43 and 44, a flag (individual specification flag) corresponding to each individual product is provided.

Thus, the clerk can recognize the details of the customer's cancellation.

  In addition, the collective designation unit 212 may receive, via the clerk input device 111, selection or cancellation of each check box operated by the clerk according to the verbal instruction of the customer on the cancel reception screen 50. In this case, the collective designation unit 212 performs drawing and erasing of a check mark on the cancellation reception screen 50, updating of the amount, and the like on the cancellation reception screen 40 in the same manner. As a result, a customer who is not accustomed to operating the touch panel can cancel the merchandise on behalf of the clerk.

The individual specification unit 213 processes the specification of the individual specification check boxes 45 and 46 on the cancel acceptance screens 40 and 50.
When the individual designation check boxes 45 and 46 are selected on the cancel reception screens 40 and 50 via the customer input device 121 or the clerk input device 111, the individual designation means 213 Draw a check mark (check point) indicating that the operation has been performed.
For example, as shown in FIG. 8, when the individual designation check box 46 is selected, a check mark is drawn in the individual designation check box 46.

  When the individual designation check boxes 45 and 46 on which the check marks are already drawn are selected, the individual designation unit 213 cancels the designation and erases the check marks of the selected individual designation check boxes 45 and 46. .

  Note that the individual designation means 213 sets the individual designation check boxes 45 and 46 in a state where a check mark is already drawn on the collective designation check box 43 or the collective designation check box 44 and the product list for each tax rate is collectively selected. Is selected, the collective designation is canceled, the check mark of the collective designation check box 43 or the collective designation check box 44 is erased, and only the check marks of the selected individual designation check boxes 45 and 46 are erased.

That is, as shown in FIG. 7, the collective designation check box 44 is selected, and the check marks are drawn in all the individual designation check boxes 46 of the second tax rate product list 42 corresponding to the tax rate (standard tax rate). When one individual specification check box 46 is selected, the individual specification unit 213 deletes the check marks in the collective specification check box 44 and the one individual specification check box 46 as shown in FIG. As a result, even when the cancellation is selected collectively by mistake, the cancellation can be individually canceled.
The individual specification unit 213 sets or resets a flag (batch specification flag, individual specification flag) according to the state of each of the check boxes 43, 44, 45, and 46, similarly to the collective specification unit 212.

When the individual designation check boxes 45 and 46 are selected or canceled, the individual designation unit 213 updates the amount for each tax rate and the total amount on the cancellation reception screen 40.
In addition, the individual specification unit 213 reflects the display state of the cancel reception screen 40 on the cancellation reception screen 50 (see FIG. 6), similarly to the collective specification unit 212, and outputs the cancellation reception screen via the clerk input device 111. At 50, the operation of the clerk is also enabled.

The accounting processing unit 22 performs accounting processing except for the products registered by the product registration unit 20 that are canceled by the cancellation processing unit 21.
For example, when the “cash” key 35b is selected on the sales registration screen 30 shown in FIG. 4, the accounting processing unit 22 executes a change calculation or the like at the time of selling cash, and sends the receipt information to the printing device 14. Output.

  In step S2, after the registration of the product is completed, that is, when the “subtotal” key 35a is selected on the sales registration screen 30 (Yes in step S2), the operation proceeds to step S3. On the other hand, when an area other than the “subtotal” key 35a is selected (No in step S2), the CPU 100 returns to step S1 and continues the product registration processing. Note that the CPU 100 may advance the operation to step S3 by selecting the “cancel” key 36.

In step S3, the CPU 100 uses the tax rate classified display means (display control means) 211 of the cancel processing means 21 to sort the list of products registered in step S1 by tax rate, and displays the cancel reception screens 40 and 50 (FIGS. 5 and 5). 6) is displayed. That is, the CPU 100 displays the clerk's cancellation reception screen 50 on the clerk's display device 112 and displays the customer's cancellation reception screen 40 on the customer's display device 122. The cancel accepting image display process in step S3 will be described later in detail with reference to FIG.
After displaying the cancel acceptance screens 40 and 50 in step S3, the CPU 100 resets the collective designation flag for each tax rate and the individual designation flag for each product (not shown as steps).

  In step S4, the CPU 100 determines that the "close" key 51 or the "confirm" key 52 has been selected on the clerk cancellation reception screen 50 (see FIG. 6) by the tax rate classified display means 211 (Yes in step S4). ), And the operation proceeds to step S8. On the other hand, when an area other than the “close” key 51 or the “confirm” key 52 is selected (No in step S4), the CPU 100 performs the operation from step S5.

In step S5, the CPU 100 causes the tax-rate-separated display means 211 to display the collective designation check box 43, on the customer's cancel reception screen 40 (see FIG. 5) or the clerk's cancellation reception screen 50 (see FIG. 6). It is determined whether or not 44 has been selected. Here, when the collective specification check boxes 43 and 44 are selected (Yes in step S5), the CPU 100 causes the collective specification unit 212 to perform the collective cancellation process in step S6. When the individual specification check boxes 45 and 46 are selected in step S5 (No in step S5), the CPU 100 causes the individual specification unit 213 to perform the individual cancellation process in step S7.
The batch cancel processing in step S6 and the individual cancel processing in step S7 will be described later in detail with reference to FIGS.

  When the “close” key 51 or the “confirm” key 52 is selected in step S4, in step S8, the CPU 100 causes the accounting processing unit 22 to select one of the commodities registered in step S1 in steps S6 and S7. Accounts are processed except for canceled products.

[Cancel reception screen display processing]
Next, with reference to FIG. 12 (see FIGS. 1 to 3 as appropriate), the cancel reception screen display processing (step S3 in FIG. 11) will be described. The cancel reception screen display processing includes processing to be displayed on the display device 112 for the clerk and processing to be displayed on the display device 122 for the customer. The “close” key 51 and the “confirm” key 52 in FIG. Since the process is the same except for the cancellation, the cancel reception screen 40 displayed on the customer display device 122 will be described as an example.

  In step S30, the CPU 100 displays fixed screen information of the cancel reception screen 40. For example, the CPU 100 displays titles (8% product, 10% product) of the first tax rate product list 41 and the second tax rate product list 42 on the cancellation reception screen 40, a list frame, and the like.

  In step S31, the CPU 100 retrieves data (product name, tax rate, unit price) from the product database DB stored in the storage device 103 using the product code of the product registered in step S1 (see FIG. 11) as a search key. get.

In step S32, the CPU 100 determines whether the tax rate acquired from the product database DB is the first tax rate (8%) or the second tax rate (10%).
Here, when the tax rate is the first tax rate (the first tax rate in step S32), the CPU 100 advances the operation to step S33. On the other hand, when the tax rate is the second tax rate (the second tax rate in step S32), the CPU 100 advances the operation to step S35.

In step S33, the CPU 100 determines whether or not the maximum number of displayed products is already displayed in the first tax rate product list 41.
Here, when the products for the maximum display number are not yet displayed in the first tax rate product list 41 (No in step S33), the CPU 100 proceeds to step S34. On the other hand, when the products for the maximum display number have already been displayed in the first tax rate product list 41 (Yes in step S33), the CPU 100 advances the operation to step S37.
When the number of products in the first tax rate product list 41 exceeds the maximum display number, the CPU 100 displays a scroll bar or the like on the first tax rate product list 41 (not shown as a step).

  In step S34, the CPU 100 displays the individual designation check box 45 on the first tax rate product list 41, and also displays the product name (for example, the product AA) acquired in step S31 and the amount corresponding to the number of the products (for example, 1000 yen). Then, the CPU 100 advances the operation to step S37.

In step S35, the CPU 100 determines whether or not the maximum number of displayed products is already displayed in the second tax rate product list 42.
Here, if the products for the maximum display number are not yet displayed in the second tax rate product list 42 (No in step S35), the CPU 100 proceeds to step S36. On the other hand, when the products for the maximum display number have already been displayed in the second tax rate product list 42 (Yes in step S35), the CPU 100 advances the operation to step S37.
When the number of products exceeds the maximum display number in the second tax rate product list 42, the CPU 100 displays a scroll bar or the like on the second tax rate product list 42 (not shown as a step).

  In step S36, the CPU 100 displays the individual designation check box 46 in the second tax rate product list 42, and also displays the product name (for example, the product AB) acquired in step S31 and the amount corresponding to the number of the products (for example, 1000 yen). Then, the CPU 100 advances the operation to step S37.

In step S37, the CPU 100 determines whether or not the screen display processing has been completed for all the products registered in step S1 (see FIG. 11) (step S37).
Here, if the screen display processing has not been completed for all the products (No in step S37), the CPU 100 returns to step S31 to continue the operation. On the other hand, when the screen display processing has been completed for all the products (Yes in step S37), the CPU 100 advances the operation to step S38.

In step S38, the CPU 100 displays the collective designation check box 43 when a product is present in the first tax rate product list 41, and displays the collective designation check box 44 when a product is present in the second tax rate product list 42. .
At this time, the CPU 100 arranges the collective designation check box 43 at a position closer to the first tax rate product list 41 than the second tax rate product list 42 and arranges a plurality of individual designation check boxes 45 of the first tax rate product list 41. Display on the extension line that is being done. In addition, the CPU 100 arranges the collective designation check box 44 at a position closer to the second tax rate product list 42 than the first tax rate product list 41 and a plurality of individual designation check boxes 46 of the second tax rate product list 42 are arranged. Displayed on the extension line that

In step S39, the total price of the product acquired in step S31 is displayed on the cancellation reception screen 40.
Note that the CPU 100 may perform the same operation as the operation described with reference to FIG. 12 to display the cancel reception screen 50. However, after the operation of FIG. 12, the CPU 100 displays the “close” key 51 and the “fix” key 52 of FIG. 6 on the cancel reception screen 50 (not shown).

[Batch cancellation process]
Next, the batch cancel process (step S6 in FIG. 11) will be described with reference to FIG. 13 (see FIGS. 1 to 3 as appropriate). There are a plurality of batch cancellation processes for each of the batch cancellation process for products with the standard tax rate and the batch cancellation process for products with the reduced tax rate.However, only the tax rates are different, and they are the same process. A description will be given of an example of a batch cancellation process of a product with a tax rate.

In step S60, the CPU 100 determines whether the collective designation check box 44 has already been selected. That is, the CPU 100 determines whether or not the collective designation check box 44 has already been selected, based on whether or not the collective designation flag of the standard tax rate is set among the flags indicating the selection state.
Here, if the collective designation check box 44 has not been selected yet (No in step S60), the CPU 100 advances the operation to step S61. On the other hand, if the collective designation check box 44 has already been selected (Yes in step S60), the CPU 100 advances the operation to step S65.

In step S61, the CPU 100 draws a check mark in the collective designation check box 44. For example, as shown in FIG. 7, the CPU 100 displays a check mark in the collective designation check box 44.
In step S62, the CPU 100 sets a standard tax rate batch designation flag. As a result, the CPU 100 retains the state in which the products of the standard tax rate are collectively canceled.

In step S63, the CPU 100 draws check marks in all the individual specification check boxes 46 in the second tax rate product list 42 having the same tax rate as the collective specification check box 44 (here, the standard tax rate). For example, as shown in FIG. 7, the CPU 100 displays a check mark in the individual designation check box 46 for all of the product AB, the product AE, the product BC, and the product CB in the second tax rate product list 42.
In step S64, the CPU 100 sets all the individual designation flags indicating the individual product selection status of the standard tax rate. Then, the CPU 100 advances the operation to step S69.

On the other hand, if the collective designation check box 44 has already been selected in step S60 (Yes in step S60), the CPU 100 deletes the check mark in the collective designation check box 44 in step S65. For example, the CPU 100 deletes the check mark of the collective designation check box 44 shown in FIG.
In step S66, the CPU 100 resets the standard tax rate batch designation flag. Thereby, the CPU 100 cancels the state in which the products of the standard tax rate are collectively canceled.

In step S67, the CPU 100 deletes the check marks of all the individual specification check boxes 46 in the second tax rate product list 42 having the same tax rate as the collective specification check box 44 (here, the standard tax rate). For example, the CPU 100 deletes the check marks attached to all the individual designation check boxes 46 of the product AB, the product AE, the product BC, and the product CB in the second tax rate product list 42 shown in FIG.
In step S68, the CPU 100 resets all the individual specification flags indicating the individual product selection status of the standard tax rate.

In step S69, the CPU 100 obtains a unit price corresponding to the product code of the product for which the individual designation flag is set from the product database DB for each tax rate, multiplies the number of the products, and cancels the sum as a total amount by tax. In addition to displaying on the reception screen 40, the total amount by tax is totaled and displayed on the cancellation reception screen 40.
Then, the CPU 100 returns the operation to step S4 (see FIG. 11).

[Individual cancellation processing]
Next, the individual cancel processing (step S7 in FIG. 11) will be described with reference to FIG. 14 (see FIGS. 1 to 3 as appropriate). Similar to the batch cancellation process, there are a plurality of individual cancellation processes for individual cancellation processes for products with the standard tax rate and individual cancellation processes for products with the reduced tax rate. Therefore, here, the individual cancellation processing of the product of the standard tax rate will be described as an example.

  In step S70, the CPU 100 determines whether or not the individual designation check box 46 has already been selected. That is, the CPU 100 determines whether or not the individual specification check box 46 has already been selected, based on whether or not the individual specification flag corresponding to the selected individual specification check box 46 among the flags indicating the selection state is set. Is determined.

  Here, if the individual designation check box 46 has not been selected yet (No in step S70), the CPU 100 advances the operation to step S71. On the other hand, when the individual designation check box 46 has already been selected (Yes in step S70), the CPU 100 advances the operation to step S73.

In step S71, the CPU 100 draws a check mark in the selected individual designation check box 46. For example, the CPU 100 displays a check mark in the individual designation check box 46 as shown in FIG.
In step S72, the CPU 100 sets the individual designation flag of the product corresponding to the selected individual designation check box 46. As a result, the CPU 100 retains the state where the individual products with the standard tax rate are canceled. Then, the CPU 100 advances the operation to step S78.

  On the other hand, if the selected individual specification check box 46 has already been selected in step S70 (Yes in step S70), in step S73, the CPU 100 determines whether the collective specification check box 44 has already been selected. judge. That is, the CPU 100 determines whether or not the collective designation check box 44 has been selected, based on whether or not the collective designation flag of the standard tax rate is set.

  Here, when the collective designation check box 44 is selected (Yes in step S73), the CPU 100 advances the operation to step S74. On the other hand, if the collective designation check box 44 is not selected (No in step S73), the CPU 100 advances the operation to step S76.

In step S74, the CPU 100 deletes the check mark of the collective designation check box 44. For example, the CPU 100 deletes the check mark of the collective designation check box 44 shown in FIG.
In step S75, the CPU 100 resets a standard tax rate batch designation flag. Thereby, the CPU 100 cancels the state in which the products of the standard tax rate are collectively canceled.

In step S76, the CPU 100 deletes the check mark of the selected individual designation check box 46. For example, as shown in FIG. 9, the CPU 100 deletes the check mark only in the individual designation check box 46 of the selected product CB.
In step S77, the CPU 100 resets the individual designation flag of the product corresponding to the selected individual designation check box 46. As a result, the CPU 100 individually cancels the state in which the commodity of the standard tax rate is canceled.

In step S78, the CPU 100 acquires, for each tax rate, the unit price corresponding to the product code of the product for which the individual designation flag is set from the product database DB, multiplies the number of products, and cancels the sum as a total price by tax. In addition to displaying on the reception screen 40, the total amount by tax is totaled and displayed on the cancellation reception screen 40.
Then, the CPU 100 returns the operation to step S4 (see FIG. 11).

  By the above operation, the electronic cash register 1 can present the customer with the cancellation acceptance screen 40 displaying the list of products for each tax rate, and can cancel the products collectively for each tax rate or individually for each product.
