However, the conventional technology disclosed in Patent Document 1 has a problem in that it is desired to perform accounting processing corresponding to multiple tax rates with a simple operation, as described below.

In Japan, a multi-rate consumption tax will go into effect in April 2017. When a multi-rate consumption tax is enforced, depending on the type of product (including services), the standard tax rate may be applied to the consumption tax accounting treatment, or the reduced tax rate, which is lower than the standard tax rate, may be applied to the consumption tax. It is applied to accounting treatment. For example, standard tax rates apply to alcoholic beverages. On the other hand, reduced tax rates are applied to food products. Therefore, accounting procedures are likely to become more complex depending on the type of product.

Furthermore, even for the same product, depending on the transaction type, the standard tax rate may be applied to the consumption tax accounting process, or the reduced tax rate may be applied to the consumption tax accounting process. For example, in restaurants serving sushi, soba, ramen, pizza, etc., there are transaction types such as in-store dining transactions, delivery transactions, and take-out transactions. Additionally, for example, if a store in the distribution industry such as a convenience store or shopping mall provides customers with eat-in space or provides a delivery service for products, the store may There are transaction types such as transaction and take-home transaction. Standard tax rates apply to dine-in transactions. On the other hand, reduced tax rates apply to food delivery and take-out transactions. Therefore, depending on the type of transaction, the standard tax rate may be applied to consumption tax accounting, or the reduced tax rate may be applied to consumption tax accounting. Therefore, there is a high possibility that accounting treatment will become complicated due to differences in transaction formats.

The conventional technology does not take into consideration the simplification of accounting processing when such multi-rate consumption tax is enforced. Therefore, when trying to perform accounting processing corresponding to consumption tax with multiple tax rates using the conventional technology, an operator such as a store clerk needs to perform complicated operations. Moreover, the operator may fail in such a complicated operation. Therefore, the conventional technology may impose a relatively large burden on the operator, and there has been a desire to perform accounting processing corresponding to multiple tax rates with a simple operation.

Further, the explanation will be made assuming that the standard tax rate is 10% and the reduced tax rate is 8%. However, the standard tax rate and reduced tax rate are subject to change. Furthermore, the reduced tax rate may include multiple tax rates.

Note that the sales data processing device 1 operates based on time measured by a timer (not shown). Further, the operation of the sales data processing device 1 is defined by a control program that is readably stored in advance in the ROM 13 or the storage section 19, and is executed by the CPU 11, which is a control section. Since these points are common practice in information processing, detailed explanations thereof will be omitted below.

A customer orders a desired product from a store clerk at a restaurant. The clerk becomes the operator of the sales data processing device 1 and operates the sales data processing device 1. Thereby, the sales data processing device 1 starts the accounting processing operation.

At this time, for example, the operator first inputs the product number into the sales data processing device 1, and then instructs the sales data processing device 1 to perform accounting processing.
In this embodiment, the product number is input by operating the numeric keys 180 (see FIG. 2) to enter the product number attached to each product, and then by operating the PLU key 181 (see FIG. 2). This will be explained as something that is done.
Further, the explanation will be given assuming that instructions to execute accounting processing are given by operating accounting key 183 (see FIG. 2). Specifically, the explanation will be made assuming that the operator first operates the subtotal key 183a and then operates the cash/deposit key 183b.

Note that the store clerk may receive orders for delivery transactions or take-out transactions. In this case, the operator (clerk) inputs the transaction type after (or before) inputting the product number, and then instructs the sales data processing device 1 to execute accounting processing. In this embodiment, the explanation will be made assuming that the operator (store clerk) inputs the transaction type after inputting the product number.

As shown in FIG. 5A, the sales data processing device 1 determines what key is operated by the operator in step S1.

If it is determined in step S1 that the operated key is the numeric key 180 (see FIG. 2), the sales data processing device 1 determines that the number input using the numeric key 180 (see FIG. 2) is the product number. is recognized as representing the product number, and in step S2, the product number displayed on the display section 14 and the customer display section 15 is updated. Thereby, the sales data processing device 1 receives the input of the product number. After this, the process returns to step S1.

If it is determined in step S1 that the operated key is the PLU key 181 (see FIG. 2), the sales data processing device 1 recognizes that the product number has been accepted, and in step S6, The product data corresponding to the input product number is read from the PLU file data Dplu (see FIG. 4D) registered in the storage unit 19 (see FIG. 2). Next, in step S7, the sales data processing device 1 calculates the subtotal amount and tax amount when the standard tax rate is applied, and in step S8, the standard tax rate is applied to the display section 14 and the customer display section 15. Display the subtotal amount and tax amount in case. After this, the process proceeds to step S10 shown in FIG. 5B via symbol A1.

As shown in FIG. 5B, the sales data processing device 1 determines what key is operated by the operator in step S10.

If it is determined in step S10 that the operated key is the numeric key 180 (see FIG. 2), the process returns to step S1 shown in FIG. 5A via symbol A2. In this case, the sales data processing device 1 recognizes that the number input using the numeric keys 180 (see FIG. 2) represents the product number to be additionally purchased, and in step S2, the sales data processing device 1 The product number displayed on the display section 15 is updated. Thereby, the sales data processing device 1 receives the input of the product number to be additionally purchased.

Further, if it is determined in step S10 that the operated key is the food delivery key 182a (see FIG. 2), the sales data processing device 1 refers to the transaction type data Dtc (see FIG. 4A) in step S14. and determine the use of formulas for food delivery transactions. In this case, the sales data processing device 1 refers to the transaction type data Dtc (see FIG. 4B), the amount calculation formula data Dex (see FIG. 4B), and the tax amount calculation formula data Dtx (see FIG. 4C) in step S16a. , based on the calculation method associated with the delivery transaction (see Figure 4A), amount calculation formula 3 (see Figure 4B), and tax amount calculation formula 3 (see Figure 4C), calculate the subtotal amount when the reduced tax rate is applied. Calculate the tax amount. Next, in step S16b, the sales data processing device 1 displays the subtotal amount and tax amount when the calculated reduced tax rate is applied on the display section 14 and the customer display section 15. After this, the process returns to step S10.

Further, if it is determined in step S10 that the operated key is the take-out key 182b (see FIG. 2), the sales data processing device 1 refers to the transaction type data Dtc (see FIG. 4A) in step S15. and determine the use of the formula for take-home transactions. In this case, the sales data processing device 1 refers to the transaction type data Dtc (see FIG. 4B), the amount calculation formula data Dex (see FIG. 4B), and the tax amount calculation formula data Dtx (see FIG. 4C) in step S16a. , based on the calculation method associated with the take-home transaction (see Figure 4A), amount calculation formula 3 (see Figure 4B), and tax amount calculation formula 3 (see Figure 4C), calculate the subtotal amount when the reduced tax rate is applied. Calculate the tax amount. Next, in step S16b, the sales data processing device 1 displays the subtotal amount and tax amount when the calculated reduced tax rate is applied on the display section 14 and the customer display section 15. After this, the process returns to step S10.

If it is determined in step S10 that the operated key is the subtotal key 183a (see FIG. 2), the sales data processing device 1 recognizes that a closing process has been instructed in step S17, The final subtotal amount, which is the accounting amount, and the final tax amount are calculated. Next, in step S18, the sales data processing device 1 displays the calculated final accounting amount and final tax amount on the display section 14 and the customer display section 15.

In the processing of steps S1 to S18, if an operation key is operated in association with a product when the specification of a product to be registered for sales is received, the first tax rate is applied to that product; In addition, when the designation of the product to be registered for sales is accepted, a second tax rate that is different from the first tax rate is applied to the product for which the operation of the operation key associated with that product is omitted, and the subtotal amount is calculated. The process is to update the display. In this embodiment, the "first tax rate" is the "reduced tax rate" and the "second tax rate" is the "standard tax rate."
After this, the process proceeds to step S20.

The customer sees the subtotal amount (account amount) displayed on the customer display section 15 and hands the cash to the operator. When the operator receives cash from the customer, the operator inputs the cash amount into the sales data processing device 1 as the deposit amount, and then operates the cash/deposit key 183b. Along with these operations, the sales data processing device 1 determines which key was operated by the operator in step S20.

If it is determined in step S20 that the operated key is the numeric key 180 (see FIG. 2), the sales data processing device 1 determines that the number input using the numeric key 180 (see FIG. 2) is the deposited amount. , and in step S21, the number of deposit amount displayed on the display section 14 and the customer display section 15 is updated. After this, the process returns to step S20.

If it is determined in step S20 that the operated key is the cash/deposit key 183b (see FIG. 2), the sales data processing device 1 recognizes that execution of accounting processing has been instructed, In step S22, accounting processing is executed and the amount of change is displayed on the display section 14 and the customer display section 15. Next, in step S23, the sales data processing device 1 creates detailed transaction data and registers it in the storage unit 19 (see FIG. 3), prints out the detailed data on a receipt in the printing unit 16, and prints out the detailed data on the receipt. Issue. Thereby, the sales data processing device 1 ends the series of operations. Thereafter, the operator hands over the purchased product, issued receipt, and change to the customer. As a result, the accounting process is completed.

<Main features of the sales data processing device>
(1) The control unit (CPU 11) of the sales data processing device 1 functions as the following display control means by executing the control program Pr (see FIG. 3).

(a) The display control means applies the first tax rate to the product if an operation key is operated in association with the product when receiving the designation of the product to be registered for sales; When the specification of the product is received, a second tax rate different from the first tax rate is applied to the product for which the operation of the operation key associated with the product is omitted, and the subtotal amount is updated and displayed.

(b) The display control means applies the first tax rate to the product if an operation key is operated in association with the product when receiving the designation of the product to be registered for sales; A second tax rate different from the first tax rate is applied to the product for which the operation of the operation key associated with the product is omitted when the designation of the product is received, and the tax amount is updated and displayed.
Such a sales data processing device 1 can present an appropriate subtotal amount and tax amount to the customer. Thereby, the sales data processing device 1 can perform accounting processing corresponding to multiple tax rates of consumption tax with a simple operation. Therefore, even if consumption tax with multiple tax rates is enforced, the burden placed on the operator can be reduced.

(2) The control unit (CPU 11) of the sales data processing device 1 functions as the following accounting processing means by executing the control program Pr (see FIG. 3).

(a) When the transaction type key 182 (see FIG. 2) is operated, the accounting processing means calculates the transaction amount based on a preset amount calculation formula corresponding to the transaction type key 182.
Such a sales data processing device 1 can perform accounting processing corresponding to multiple tax rates of consumption tax with a simple operation. Therefore, even if consumption tax with multiple tax rates is enforced, the burden placed on the operator can be reduced.

(b) The accounting processing means calculates the amount of money when the transaction type key 182 corresponding to a transaction to which the standard tax rate is applied is operated when the main price of the product is a tax-exclusive price that does not include consumption tax. The amount based on the amount calculation formula of ``Product price x (100 + standard tax rate (%)) / 100'' is calculated as the accounting amount.

(c) The accounting processing means is such that when the main price of the product is a tax-inclusive price that includes consumption tax at the standard tax rate, and when the transaction type key 182 corresponding to a transaction to which the standard tax rate is applied is operated, The amount based on the amount calculation formula where "amount = main price of the product" is calculated as the accounting amount.

(d) The accounting processing means determines that when the main price of the product is a tax-exclusive price that does not include consumption tax and the transaction type key 182 corresponding to a transaction to which the reduced tax rate is applied is operated, "Amount = The amount based on the amount calculation formula of ``Product price x (100 + reduced tax rate (%)) / 100'' is calculated as the accounting amount.

(e) The accounting processing means is when the main price of the product is a tax-inclusive price that includes consumption tax at the standard tax rate, and when the transaction type key 182 corresponding to a transaction to which the reduced tax rate is applied is operated. The amount based on the amount calculation formula where "amount = main price of the product" is calculated as the accounting amount.

(f) The accounting processing means creates detailed data representing the accounting amount calculated at the time of accounting for the product. For example, the accounting processing means creates detailed data including the price of the product when the delivery key 182a (see FIG. 2) is operated.
(f-1) Specifically, as shown in FIG. 7A, for example, when the main price of the product is a tax-exclusive price that does not include consumption tax at the standard tax rate, and the delivery key 182a (See Figure 2) is operated, the amount obtained by adding the product price and the reduced tax rate consumption tax is calculated as the accounting amount for the delivery transaction, and the accounting amount for the delivery transaction is included. Create detailed data. Therefore, the operator can cause the sales data processing device 1 to automatically calculate the accounting price to which the reduced tax rate is applied, based on the reduced tax rate applied price of the product, simply by operating the delivery key 182a.
(f-2) For example, as shown in FIG. 7B, the accounting processing means is used when the main price of the product is a tax-inclusive price that includes consumption tax at the standard tax rate, and the delivery key 182a (see FIG. 2) ) is operated, the amount obtained by changing the consumption tax at the standard tax rate to the consumption tax at the reduced tax rate based on the product price is calculated as the accounting amount for the delivery transaction, and the accounting amount for the delivery transaction is included. Create the detailed data that is included. Therefore, by simply operating the delivery key 182a, the operator has the sales data processing device 1 perform the following operations based on the product's standard tax rate applicable price (that is, the product's main price that includes consumption tax at the standard tax rate). The accounting price to which the reduced tax rate is applied can be automatically calculated.

(g) Accounting processing means include receipt printout using a printer (not shown), audio output from a speaker (not shown), display output from displays such as the display section 14 and the customer display section 15, and transfer output to an external device (not shown). The created detailed data can be output in one or more of the following output formats. Note that the external device is, for example, a server (not shown) installed outside, a smartphone (not shown) owned by the customer, or the like.
The server transfers the detailed data to, for example, a portable POS terminal device carried by a delivery person during a delivery transaction. Thereby, the delivery person can perform accounting processing at the delivery destination based on the transferred detailed data.
Further, the smartphone receives, for example, detailed data as an electronic receipt (or data that is the source of the electronic receipt). This allows customers to use electronic receipts for household account books and the like.

(3) The input unit 18 includes a plurality of transaction type keys 182. The amount calculation formula differs for each transaction type key 182. Thereby, the sales data processing device 1 can perform accounting processing tailored to various product types and transaction types.

(4) In this embodiment, the standard tax rate is 10% and the reduced tax rate is 8%. However, the standard tax rate value and the reduced tax rate value are subject to change. Furthermore, the reduced tax rate may include multiple tax rates. Even in such a case, the sales data processing device 1 changes the transaction type data Dtc (see FIG. 4A), the amount calculation formula data Dex (see FIG. 4B), and the tax amount calculation formula data Dtx (see FIG. 4C). It is possible to apply it easily.

As described above, according to the sales data processing device 1 according to the present embodiment, accounting processing corresponding to multiple tax rates can be executed with a simple operation.

Note that the present invention is not limited to the embodiments described above, and various changes and modifications can be made without departing from the gist of the present invention.
For example, the embodiments described above have been described in detail in order to explain the gist of the present invention in an easy-to-understand manner. Therefore, the present invention is not necessarily limited to having all the components described. Further, in the present invention, other components can be added to certain components, or some components can be changed to other components. Further, in the present invention, some components can also be deleted.

Further, for example, in the embodiment described above, the sales data processing device 1 is described as being configured as a compact type electronic cash register (ECR). However, the sales data processing device 1 may be configured as an electronic device other than a compact electronic cash register, such as a high-performance POS (Point Of Sales) terminal device or a tablet terminal device. Note that when the tablet terminal device is used as an accounting processing device, a barcode scanner, printing section 16 (printer), drawer 17, etc. (not shown) are connected to the tablet terminal device.

In this configuration, the control program Pr (see FIG. 3) functions as a display control means that causes the control unit (CPU) of the electronic device to update and display the subtotal amount and tax amount for one transaction every time it receives a specification of a product to be registered for sales. let

Further, the control program Pr (see FIG. 3) causes the control unit (CPU) of the electronic device to function as an accounting processing means for executing accounting processing corresponding to consumption tax with multiple tax rates. That is, when the transaction type key is operated, the control program Pr functions as an accounting processing means that calculates the transaction amount based on an amount calculation formula set in advance corresponding to the transaction type key.

Further, for example, the structure of the transaction type data Dtc shown in FIG. 4A and the contents of the data included therein can be changed as appropriate depending on the operation. Similarly, the structure of the amount calculation formula data Dex shown in FIG. 4B and the contents of the data included therein can be changed as appropriate depending on the operation.

Further, for example, the operation example of the sales data processing device 1 described above (see FIGS. 5A and 5B) is only an example, and can be changed as appropriate depending on the operation. For example, when a customer purchases multiple types of products, the sales data processing device 1 operates appropriately.

Furthermore, for example, the sales data processing device 1 can create sales data in which the sales amounts of each transaction are totaled, based on detailed data created during the accounting process for the product. Owners of each store often look at the daily accounting column that summarizes daily sales amounts. Therefore, the daily account column of the sales data created by the sales data processing device 1 is preferably configured such that the sales amount to which the standard tax rate applies and the sales amount to which the reduced tax rate applies can be distinguished.
