Description

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

Conventionally, as a sales data processing device installed in a store that sells products (including services) and accepts the designation of sales registration of products, a compact type electronic cash register (ECR) and a high-performance type POS (ECR) Point Of Sales) Electronic devices such as terminal devices are known.
When the sales data processing device receives an instruction to execute the accounting process at the time of selling the product, the sales data processing device calculates the accounting amount and the consumption tax of the product for which the designation of the sales registration is accepted, and executes the accounting process of the product.

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

Japanese Unexamined Patent Publication No. 2003-256937

When the consumption tax of a plurality of tax rates is enforced, the prior art described in Patent Document 1 has the following problems.
In the prior art, the standard tax rate is applied to the accounting treatment of consumption tax, or the reduced tax rate, which is lower than the standard tax rate, is applied to the accounting treatment of consumption tax, depending on the type of goods (including services). Even if the products are the same, the standard tax rate may be applied to the consumption tax accounting process, or the reduced tax rate may be used for consumption tax accounting, depending on the transaction form (for example, in-store food and drink transactions, take-out transactions, etc.). It is applied to processing.
That is, in the prior art, even if there are a plurality of products having different tax rates, the products are sold by subtotaling them all at once.

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

An object of the present invention is to allow a customer to cancel the purchase of a product at an unintended tax rate before accounting for the product.

In order to solve the above problems, the sales data processing device according to the present invention includes display control means for displaying a list of products for which sales registration is specified in one transaction in association with the tax rate applied to the products. The display control means is characterized in that the first selection means for collectively selecting the products whose sales registration designation is canceled from the list of the products for each tax rate is displayed.
Further, the program according to the present invention functions as a display control means for displaying the computer of the sales data processing device in association with the tax rate applied to the product by displaying a list of products for which the designation of sales registration is accepted in one transaction. The display control means is characterized in that the first selection means for collectively selecting the products whose sales registration designation is canceled from the list of the products for each tax rate is displayed.

According to the present invention, it is possible to cancel the purchase of a product at a tax rate unintended by the customer before accounting for the product.

As shown in FIG. 3, the sales registration control unit 2 includes a product registration means 20, a cancellation processing means 21, and an accounting processing means 22. That is, the control program Pr is composed of a program that functions as the product registration means 20, a program that functions as the cancellation processing means 21, and a program that functions as the accounting processing means 22.

The product registration means 20 registers the product (including the service) purchased by the customer in the electronic cash register 1. The product registration means 20 displays the sales registration screen on the store clerk display device 112, and registers the product selected by the store clerk operating (touching) the customer input device 121.
Specifically, the process of the product registration means 20 will be described by taking the sales registration screen 30 shown in FIG. 4 as an example.
The sales registration screen 30 shown in FIG. 4 is mainly composed of a product selection area 31, a group selection area 32, a slip area 33, a numeric keypad area 34, and an accounting instruction area 35.

The product selection area 31 is an area for selecting a product by displaying a plurality of selection candidates 31a including a product name and its unit price as a list. The product registration means 20 refers to the product database DB (see FIG. 10) and displays a list of products belonging to the group selected in the group selection area 32. In addition, the product registration means 20 sequentially displays the selection candidates 31a selected by the clerk in the slip area 33. At this time, the product registration means 20 refers to the product database DB and displays a list of products for each tax rate corresponding to the selected product.
The group selection area 32 is an area for displaying groups (groups A, B, ...) For classifying products and selecting a group.

The slip area 33 is an area for displaying the product (product name), the quantity, and the amount (unit price × quantity) of the product selected in the product selection area 31 by tax rate. The product registration means 20 refers to the product database DB and displays the selected products in the slip area 33 according to the tax rate. At this time, if the number in the numeric keypad area 34 is selected before the product is selected, the product registration means 20 calculates the amount by multiplying the selected number by the unit price of the selected product.

At this time, the product registration means 20 may display the subtotal amount on the sub display device 13.
When the "subtotal" key 35a is selected, the cancellation acceptance screens 40 and 50 for canceling the products registered by the cancellation processing means 21 collectively or individually are displayed. In addition to the "subtotal" key 35a, the cancellation acceptance screens 40 and 50 may be displayed by separately selecting the "cancel" key 36.
The "cash" key 35b is an area instructed when purchasing a product in cash. When the "cash" key 35b is selected, the product registration means 20 outputs an instruction to open the cash storage unit to the drawer 15.
Returning to FIG. 3, the description of the control program configuration will be continued.

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

The display means (display control means) 211 classifies the list of products for which sales registration is specified in one transaction according to the tax rate applied to the products, and accepts the cancellation of the products (cancellation acceptance screen 40, 50 [see FIGS. 5 and 6]) is displayed. The tax rate classification display means 211 refers to the product database DB (see FIG. 10), and displays the cancellation reception screens 40 and 50 for the clerk display device 112, which divides the list of products registered by the product registration means 20 by tax rate. And the customer display device 122, respectively.
When the cancellation reception screen 50 is displayed on the clerk display device 112, the tax rate classification display means 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 cancellation reception screen 50 is superimposed.

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

Specifically, the tax rate classification display means 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 in the product registration means 20. Displays the product name and unit price (amount) of the product having the first tax rate (here, the reduced tax rate is 8%) as the first tax rate product list 41. In addition, the tax rate classification display means 211 is 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 means 20 is the second tax rate (here, the standard tax rate is 10%). Is displayed as the second tax rate product list 42.

Here, the tax rate classification display means 211 displays the batch designation check boxes (first check boxes) 43 and 44 for instructing the cancellation of the product list by tax rate at once on the cancellation reception screen 40. .. In addition, the tax rate classification display means 211 has a plurality of individually designated check boxes (second check boxes) for individually canceling the 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 more products than the maximum number of items displayed in each list are registered as the first tax rate product list 41 and the second tax rate product list 42, the tax rate classification display means 211 displays a scroll bar in each list. It enables scrolling in the list.

The batch designation check box 43 is an area for designating the batch cancellation of products having a reduced tax rate (8%). The tax rate classification 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. It is preferable that the batch designation check box 43 is displayed on an extension line in which a plurality of individual designation check boxes 45 of the first tax rate product list 41 are arranged.
This makes it possible to prevent the customer from erroneously recognizing the batch designation check box 43 as a check box for batch cancellation with respect to the standard tax rate.

The batch designation check box 44 is an area for designating the batch cancellation of products having a standard tax rate (10%). The tax rate classification display means 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. It is preferable that the batch designation check box 44 is displayed on an extension line in which a plurality of individual designation check boxes 46 of the second tax rate product list 42 are arranged.
This makes it possible to prevent the customer from erroneously recognizing the batch designation check box 44 as a batch cancellation check box for the reduced tax rate.

The individual designation check box 45 is an area for designating the individual cancellation of the reduced tax rate products. The tax rate classification display means 211 displays the individual designation check box 45 at a position closer to the individual products in the first tax rate product list 41 than the other products. This prevents the customer from accidentally canceling another product with a reduced tax rate.

The individual designation check box 46 is an area for designating the individual cancellation of the products having the standard tax rate. The tax rate classification display means 211 displays the individual designation check box 46 at a position closer to the individual products in the second tax rate product list 42 than the other products. This prevents the customer from accidentally canceling other products with a standard tax rate.
Further, the tax rate classification display means 211 preferably displays the amount of money by tax rate or the total amount of money when the cancellation is carried out on the cancellation reception screen 40, as shown in FIG. This allows the customer to recognize the canceled amount of the item.

Next, an example of the cancellation acceptance screen 50 displayed on the clerk display device 112 by the tax rate classification display means 211 will be described with reference to FIG.
The cancellation reception screen 50 is a screen for the clerk to grasp the content of the cancellation made 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 classification display means 211 displays the same contents as the cancellation acceptance screen 40 as the cancellation acceptance screen 50.
Further, the tax rate classification display means 211 further displays the "close" key 51 and the "confirmation" key 52 on the cancellation acceptance screen 50.

The "close" key 51 is an area for instructing the cancellation acceptance screen 50 and the cancellation acceptance screen 40 (see FIG. 5) displayed on the customer display device 122 to be closed without canceling. This "close" key 51 is used when the customer does not cancel, but the customer cancels, but the cancellation is not actually performed, such as when the customer wants to cancel the cancellation at once. Selected by the clerk.

The “confirmation” key 52 is an area for instructing the confirmation of the content of the cancellation made by the customer. The "confirmation" key 52 is selected by the clerk after the clerk confirms the consent of the cancellation contents to the customer. As a result, the actual content of the cancellation is confirmed. When the "confirm" key 52 is selected, the cancellation acceptance screen 50 and the cancellation acceptance screen 40 (see FIG. 5) displayed on the customer display device 122 are closed.
Returning to FIG. 3, the description of the control program configuration will be continued.

At this time, the tax rate classification display means 211 holds the state in which the check box is selected during the operation of the cancellation processing means 21, and therefore, as an internal state, a flag indicating a batch cancellation state by tax rate on the RAM 101 ( A batch designation flag) and a flag indicating the individual cancellation status for each product (individual designation flag) are prepared and reset in advance when the cancellation acceptance screens 40 and 50 are displayed.
The tax rate classification display means 211 shifts to the operation of the accounting processing means 22 by selecting the "close" key 51 or the "confirmation" key 52.

The batch designation means 212 processes the designation of the batch designation check boxes 43 and 44 on the cancellation acceptance screens 40 and 50.
When the batch designation check boxes 43 and 44 are selected via the customer input device 121 or the clerk input device 111 on the cancellation acceptance screens 40 and 50, the batch designation means 212 selects the check boxes. Draw a check mark (check mark) indicating that the check mark has been made.

Further, when the batch designation check boxes 43 and 44 are selected, the batch designation means 212 draws check marks on all of the individual designation check boxes 45 and 46 in the product list corresponding to the tax rate of the selected check box. I will do it. This makes it possible to more clearly indicate to the customer that all products by the selected tax rate have been subject to cancellation.
For example, as shown in FIG. 7, when the batch designation check box 44 is selected, a check mark is drawn in the batch designation check box 44, and the second tax rate product list 42 of the standard tax rate corresponding to the batch designation check box 44 42. Check marks are drawn in all the individually specified check boxes 46 of.

Further, when the batch designation check boxes 43 and 44 on which the check marks have already been drawn are selected, the batch designation means 212 cancels the batch designation, deletes the check marks of the batch designation check boxes 43 and 44, and selects them. In the product list corresponding to the tax rate of the checked check box, all the check marks of the individually specified check boxes 45 and 46 are deleted.
When the batch designation check boxes 43 and 44 are selected, the batch designation means 212 sets a flag (batch designation flag) corresponding to each tax rate in order to maintain the state. Further, when the selection of the batch designation check boxes 43 and 44 is canceled, the batch designation means 212 resets the flags (batch designation flags) corresponding to the respective tax rates.

Further, when the batch designation means 212 selects or cancels the individual designation check boxes 45, 46 by selecting or canceling the batch designation check boxes 43, 44, the flag corresponding to each individual product (individual designation flag). To set or reset.

Further, when the batch designation check boxes 43 and 44 are selected or canceled, the batch designation means 212 updates the amount for each tax rate and the total amount on the cancellation acceptance screen 40.
The batch designation means 212 draws and erases the check mark on the cancellation acceptance screen 40, updates the amount of money, and the like on the cancellation acceptance screen 50 (see FIG. 6) in the same manner. As a result, the clerk can recognize the cancellation contents of the customer.

Further, the batch designation means 212 may accept selection or cancellation of each check box operated by the clerk according to the verbal instruction of the customer on the cancellation acceptance screen 50 via the clerk input device 111. In that case, the batch designation means 212 draws and erases the check mark on the cancellation acceptance screen 50, updates the amount of money, and the like on the cancellation acceptance screen 40 as well. As a result, the clerk can cancel the product on behalf of the customer who is unfamiliar with the operation of the touch panel.

The individual designation means 213 processes the designation of the individual designation check boxes 45 and 46 on the cancellation acceptance screens 40 and 50.
When the individual designation check boxes 45 and 46 are selected via the customer input device 121 or the clerk input device 111 on the cancellation acceptance screens 40 and 50, the individual designation means 213 selects the check boxes. Draw a check mark (check mark) indicating that the check mark has been made.
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.

Further, when the individual designation check boxes 45 and 46 on which the check marks have already been drawn are selected, the individual designation means 213 cancels the designation and deletes the check marks of the selected individual designation check boxes 45 and 46. ..

In the individual designation means 213, a check mark has already been drawn in the batch designation check box 43 or the batch designation check box 44, and the product list by tax rate is collectively selected, and the individual designation check boxes 45 and 46 are selected. When is selected, the batch designation is canceled, the check marks of the batch designation check box 43 or the batch designation check box 44 are deleted, and only the check marks of the selected individual designation check boxes 45 and 46 are deleted.

That is, as shown in FIG. 7, the batch 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 designation check box 46 is selected, the individual designation means 213 deletes the check mark in the batch designation check box 44 and the one individual designation check box 46 designated as shown in FIG. As a result, even if you mistakenly select cancel all at once, you can cancel the cancellation individually.
Note that the individual designation means 213 sets or resets flags (batch designation flag, individual designation flag) according to the states of the check boxes 43, 44, 45, 46, similarly to the batch designation means 212.

Further, when the individual designation check boxes 45 and 46 are selected or canceled, the individual designation means 213 updates the amount for each tax rate and the total amount on the cancellation acceptance screen 40.
Further, the individual designation means 213 reflects the display state of the cancellation reception screen 40 on the cancellation reception screen 50 (see FIG. 6) as in the batch designation means 212, and also transmits the cancellation reception screen via the clerk input device 111. At 50, the operation of the clerk is also possible.

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

The CPU 100 may proceed to step S3 by selecting the "cancel" key 36.

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

In step S4, when the "close" key 51 or the "confirm" key 52 is selected by the tax rate classification display means 211 on the cancellation reception screen 50 for the clerk (see FIG. 6) (Yes in step S4). ), 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 operations after step S5.

In step S5, the CPU 100 uses the tax rate classification display means 211 to display the batch designation check box 43 on the cancellation reception screen 40 for customers (see FIG. 5) or the cancellation reception screen 50 for clerk (see FIG. 6). Determine if 44 is selected. Here, when the batch designation check boxes 43 and 44 are selected (Yes in step S5), the CPU 100 performs the batch cancellation process in step S6 by the batch designation means 212. Further, when the individual designation check boxes 45 and 46 are selected in step S5 (No in step S5), the CPU 100 performs the individual cancellation process of step S7 by the individual designation means 213.
The batch cancellation process in step S6 and the individual cancellation process in step S7 will be described in detail later with reference to FIGS. 13 and 14.

When the "close" key 51 or the "confirm" key 52 is selected in step S4, in step S8, the CPU 100 is set in steps S6 and S7 among the products registered in step S1 by the accounting processing means 22. Accounting is performed except for canceled products.

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

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

In step S31, the CPU 100 uses the product code of the product registered in step S1 (see FIG. 11) as a search key to obtain data (product name, tax rate, unit price) from the product database DB stored in the storage device 103. 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 (first tax rate in step S32), the CPU 100 proceeds to the operation in step S33. On the other hand, when the tax rate is the second tax rate (second tax rate in step S32), the CPU 100 proceeds to the operation in step S35.

In step S33, the CPU 100 determines whether or not the products corresponding to the maximum number of products to be displayed are already displayed on the first tax rate product list 41.
Here, if the maximum number of displayed products is not yet displayed in the first tax rate product list 41 (No in step S33), the CPU 100 proceeds to the operation in step S34. On the other hand, when the maximum number of displayed products is already displayed in the first tax rate product list 41 (Yes in step S33), the CPU 100 proceeds to the operation in step S37.
When the number of products in the first tax rate product list 41 exceeds the maximum number of displayed products, the CPU 100 displays a scroll bar or the like in 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 in the first tax rate product list 41, and also displays the product name (for example, product AA) acquired in step S31 and the amount of money corresponding to the number of the products (for example). 1000 yen) is displayed. Then, the CPU 100 advances the operation to step S37.

In step S35, the CPU 100 determines whether or not the products corresponding to the maximum number of products to be displayed are already displayed on the second tax rate product list 42.
Here, if the maximum number of displayed products is 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 number of displayed products are already displayed in the second tax rate product list 42 (Yes in step S35), the CPU 100 proceeds to the operation in step S37.
When the number of products in the second tax rate product list 42 exceeds the maximum number of displayed products, the CPU 100 displays a scroll bar or the like in 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 on the second tax rate product list 42, and also displays the product name (for example, product AB) acquired in step S31 and the amount of money corresponding to the number of the products (for example). 1000 yen) is displayed. 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 for all the products has not been completed yet (No in step S37), the CPU 100 returns to step S31 and continues the operation. On the other hand, when the screen display processing is completed for all the products (Yes in step S37), the CPU 100 proceeds to the operation in step S38.

In step S38, the CPU 100 displays the batch designation check box 43 when the product exists in the first tax rate product list 41, and displays the batch designation check box 44 when the product exists in the second tax rate product list 42. ..
At this time, the CPU 100 arranges the batch 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 a plurality of individual designation check boxes 45 of the first tax rate product list 41 are arranged. Display on the extension line. Further, the CPU 100 arranges the batch 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. Display on the extension line.

In step S39, the total amount of the products acquired in step S31 is displayed on the cancellation acceptance screen 40.
In order to display the cancellation acceptance screen 50, the CPU 100 may perform the same operation as that described with reference to FIG. However, after the operation of FIG. 12, the CPU 100 displays the "close" key 51 and the "confirm" key 52 of FIG. 6 on the cancellation acceptance screen 50 (not shown).

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

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

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

In step S63, the CPU 100 draws check marks in all the individually designated check boxes 46 in the second tax rate product list 42 having the same tax rate (here, the standard tax rate) as the batch designated check box 44. For example, as shown in FIG. 7, the CPU 100 displays a check mark in the individually designated 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 selection status of each product at the standard tax rate. Then, the CPU 100 advances the operation to step S69.

On the other hand, if the batch designation check box 44 is already selected in step S60 (Yes in step S60), the CPU 100 erases the check mark of the batch designation check box 44 in step S65. For example, the CPU 100 erases the check mark of the batch designation check box 44 shown in FIG.
In step S66, the CPU 100 resets the standard tax rate batch designation flag. As a result, the CPU 100 cancels the state in which the products having the standard tax rate are collectively canceled.

In step S67, the CPU 100 deletes all the check marks of the individually designated check boxes 46 in the second tax rate product list 42 having the same tax rate (here, the standard tax rate) as the batch designated check box 44. For example, the CPU 100 erases the check marks attached to all the individually designated 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 designation flags indicating the selection status of each product at the standard tax rate.

In step S69, the CPU 100 acquires the unit price corresponding to the product code of the product for which the individually specified flag is set for each tax rate from the product database DB, multiplies the number of the products, and cancels as the total amount excluding tax. In addition to displaying on the reception screen 40, the total amount excluding 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 process]
Next, the individual cancellation process (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 multiple individual cancellation processes for individual cancellation processing for products with a standard tax rate and individual cancellation processing for products with a reduced tax rate. Therefore, here, an individual cancellation process for a product with a 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 depending on whether or not the individual specification flag corresponding to the selected individual specification check box 46 is set among the flags indicating the selection state. Is determined.

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

In step S71, the CPU 100 draws a check mark in the selected individually specified check box 46. For example, as shown in FIG. 8, the CPU 100 displays a check mark in the individual designation check box 46.
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 keeps the canceled state for each individual product at the standard tax rate. Then, the CPU 100 advances the operation to step S78.

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

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

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

In step S76, the CPU 100 erases the check mark of the selected individual designation check box 46. For example, as shown in FIG. 9, the CPU 100 erases only 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 canceled state of the standard tax rate product.

In step S78, the CPU 100 acquires the unit price corresponding to the product code of the product for which the individually specified flag is set for each tax rate from the product database DB, multiplies the number of the products, and cancels as the total amount excluding tax. In addition to displaying on the reception screen 40, the total amount excluding 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 presents the cancellation acceptance screen 40 displaying the product list by tax rate to the customer, and can cancel the products collectively by tax rate or individually for each product.
