JP 2014-38654 A

  In Japan, a multi-tax consumption tax will be enforced in April 2017. When this multi-tax consumption tax is enforced, the standard tax rate (10%) is applied to consumption tax accounting due to differences in the types of products (including services), and the reduced tax rate is lower than the standard tax rate. (8%) will be applied to consumption tax accounting.

However, when a consumption tax with multiple tax rates is enforced, the conventional sales data processing apparatus has the following problems.
In the conventional sales data processing apparatus, since the tax rate is included in the product master, it is necessary to set the tax rate for each product while checking all the products in the product master. Furthermore, in the conventional sales data processing apparatus, when selling one product at a plurality of tax rates depending on conditions, a tax rate is set for each sale, or a plurality of tax rates can be used for one product. There is a need to. For this reason, in the conventional sales data processing apparatus, considerable labor is required for setting multiple tax rates.

  An object of the present invention is to reduce the labor required for setting multiple tax rates.

To solve the above problem,
In the sales data processing apparatus of the present invention, at the time of initial setting, when a product to be registered for sales is selected, the first tax rate is once applied to display a price, or a second tax rate different from the first tax rate is applied once Selection means for selecting whether to display the applicable tax rate in advance before displaying the price, or setting means for setting the tax rate application corresponding to the product registered for sales, according to the content selected by the selection means And.

  According to the present invention, labor required for setting a plurality of tax rates can be reduced.

The product masters 110a to 110c and the product master management 111 will be described with reference to FIGS.
In the present embodiment, as shown in FIG. 3, the electronic cash register 1 uses the original product master 110a before the consumption tax of a plurality of tax rates is enforced at a tax 1 (first tax rate). Copying is made to the master 110b and the tax 2 product master 110c used at the tax 2 (second tax rate) (product master copy process).

  Here, the consumption tax rate before the consumption tax of multiple tax rates is enforced is 8%. In addition, the tax rate of tax 1 is the reduced tax rate (8%) after the consumption tax of multiple tax rates is enforced. In addition, the tax rate of tax 2 is the standard tax rate (10%) after the consumption tax of multiple tax rates is enforced. Needless to say, the tax rates of the product masters 110a to 110c are not limited to these.

As shown in FIG. 4, the product master 110a holds a product code, a product name corresponding to the product code, a tax rate, and a written character. , “Notation characters”.
“Product code” is an identification code for uniquely identifying a product. “Product name” is the name of the product. “Tax rate” indicates a consumption tax rate before a multi-tax consumption tax is enforced. “Notation character” indicates a character indicating a tax rate.

As shown in FIG. 5, the product master 110b for tax 1 is a product master used for tax 1, and is composed of “product code”, “product name”, “tax rate”, and “notation characters”. The This “tax rate” indicates the tax rate of tax 1.
As shown in FIG. 6, the tax 2 merchandise master 110c is a merchandise master used for tax 2, and is composed of “product code”, “product name”, “tax rate”, and “notation characters”. The This “tax rate” indicates the tax rate of tax 2.

The printing unit 13 prints a receipt after performing the accounting process, and is, for example, a thermal transfer printer. The printing unit 13 prints receipt information input from the main body unit 10 on roll paper (receipt paper) and outputs it.

<Product Master Copy Processing>
The product master copy process will be described with reference to FIGS. 8 and 9 (see FIG. 2 as appropriate).
This product master copy process is a process of copying the product master 110a to the tax 1 product master 110b and the tax 2 product master 110c (FIG. 3). Here, the timing for executing the merchandise master copy process is not particularly limited, but may be executed when the electronic cash register 1 is initially set, for example.

  The CPU 100 displays a tax rate input screen on the input display unit 11, asks the store clerk what the tax rates for tax 1 and tax 2 and the written characters are to be entered, and inputs them (step S1).

  As shown in FIG. 9, the tax rate input screen 200 includes a “tax 1 tax rate” field 201 for inputting a tax 1 tax rate, a “tax 1 notation character” field 202 for inputting a tax 1 notation character, and a tax 2 A “tax 2 tax rate” field 203 for inputting a tax rate, a “tax 2 notation character” field 204 for inputting a tax 2 notation character, and a “confirm” button 205 are provided. Here, when all the fields 201 to 204 are input by the store clerk and the “confirm” button 205 is pressed, the process proceeds to step S <b> 2.

The CPU 100 copies the product master 110a to the tax 1 product master 110b (step S2).
The CPU 100 copies the product master 110a to the tax 2 product master 110c (step S3).

The CPU 100 changes all the products in the tax 1 product master 110b to the tax 1 tax rate and the notation characters input in step S1 (step S4).
The CPU 100 changes all the products in the tax 2 product master 110c to the tax 2 tax rate and notation characters input in step S1 (step S5).

<Product sales processing>
The merchandise sales process will be described with reference to FIG. 10 (see FIG. 2 as appropriate).
This merchandise sales process is a process in which the store clerk designates the merchandise to be registered for sales in the electronic cash register 1. At this time, in the sales process of the product, it is selected whether the designated product uses the tax 1, the tax 2, or the tax rate is selected every time. Then, the conventional sales registration process is performed at the selected tax rate.

The store clerk operates the input display unit 11 to specify a product to be sold with a product code or the like (step S10).
The CPU 100 determines whether or not the designated product is in the product master management 111 (step S11).

If the specified product is in the product master management 111 (Yes in step S11), the CPU 100 performs a variable substitution process used in a sales registration process described later (step S12).
This variable stores the tax rate and notation characters of the specified product. Details of the variable substitution process will be described later.

  The CPU 100 performs the sales registration process for the product specified in step S10 using the tax rate and the written characters assigned to the variables (step S13), and ends the process.

When the designated product is not in the product master management 111 (No in step S11), the CPU 100 determines whether or not the designated product is in the tax 1 product master 110b (step S14).
When the designated product is not in the tax 1 product master 110b (No in step S14), the CPU 100 determines whether or not the designated product is in the tax 2 product master 110c (step S15).

When the designated product is in the tax 2 product master 110c (Yes in step S15), the CPU 100 records the designated product in the product master management 111 when the tax 2 is used. That is, the CPU 100 records the tax use type of the designated product as “2” in the product master management 111 (step S16).
The CPU 100 substitutes the tax rate and the written characters of the tax 2 commodity master 110c into variables used in the sales registration process (step S17), and proceeds to the process of step S13.

  When the designated product is in the tax 1 product master 110b (Yes in step S14), the CPU 100 determines whether or not the designated product is in the tax 2 product master 110c (step S18).

When the specified product is not in the tax 2 product master 110c (No in step S18), the CPU 100 records the specified product in the product master management 111 when the tax 1 is used. That is, the CPU 100 records the tax use type of the designated product as “1” in the product master management 111 (step S19).
The CPU 100 substitutes the tax rate and the written characters of the tax 1 commodity master 110b into variables used in the sales registration process (step S20), and proceeds to the process of step S13.

When the designated product is in the tax 2 product master 110c (Yes in step S18), the CPU 100 performs a process of selecting a tax rate to be used (step S21). Details of the tax rate selection process will be described later.
The CPU 100 performs a variable substitution process used in the sales registration process with the tax rate and the notation characters selected in the tax rate selection process (step S22), and proceeds to the process of step S13.

  When the designated product is not in the tax 2 product master 110c (No in step S15), the CPU 100 performs a conventional process when there is no designated product (step S23), and ends the process.

  By the sales process of this product, the price of each product is displayed according to the tax rate set for each product. For example, if the tax rate of “Product 1” is set at 8%, “Product price 1000 yen, tax amount 80 yen” or “Tax included price 1080 yen (including tax 80 yen)” will be displayed on the sales registration screen 210 described later. The price is displayed. After that, if the tax rate of “Product 1” is changed from 8% to 10%, “Product Price 1000 yen, Tax amount 100 yen” or “Tax included price 1100 yen (including tax 100 yen)” will be displayed on the sales registration screen 210. So that the price is displayed. Further, when the tax rate of “product 1” is returned from 10% to 8%, the price display corresponding to the tax rate of 8% is returned.

<Tax rate selection process>
With reference to FIG. 11, the tax rate selection process in step S21 of FIG. 10 will be described (see FIG. 2 as appropriate).
This tax rate selection process is a process in which the store clerk selects (specifies) whether to use tax 1, use tax 2, or select a tax rate each time, and records it in the merchandise master management 111.

  The CPU 100 displays a designation guidance to be described later on the input display unit 11, inquires of the store clerk whether to use tax 1, tax 2, or selection every time, and inputs the tax rate to be used (step S30).

The CPU 100 determines whether or not an input is made when tax 1 is used (step S31).
If input is made using tax 1 (Yes in step S31), the CPU 100 records the specified product in the product master management 111 when tax 1 is used. That is, the CPU 100 records the tax use type of the designated product as “1” in the product master management 111 (step S32), and ends the process.

  When the tax 1 is not used (No in step S31), the CPU 100 determines whether the tax 2 is used or not (step S33).

  If it is input that the tax 2 is used (Yes in step S33), the CPU 100 records the specified product in the product master management 111 when the tax 2 is used. That is, the CPU 100 records the tax use type of the designated product as “2” in the product master management 111 (step S34), and ends the process.

  When the tax 2 is not used for input (No in step S33), the CPU 100 records the tax rate in the product master management 111 when the designated product selects the tax rate each time. That is, the CPU 100 records the tax use type of the designated product as “3” in the product master management 111 (step S35), and ends the process.

<< Designated guidance: First example >>
The designation guidance will be described with reference to FIGS.
As shown in FIG. 12, the designation guidance 220 is displayed in a pop-up on the sales registration screen 210. For example, when the tax rate of “product 6” is designated, a message “Please specify the tax rate of product 6” is displayed in the designation guidance 220. Further, the designation guidance 220 includes a “tax 1” button 221 indicating use of tax 1, a “tax 2” button 223 indicating use of tax 2, and a “select every time” button 225 indicating selection of a tax rate each time. .

  When the “Tax 1” button 221 is pressed, a confirmation guidance 230 pops up on the sales registration screen 210 as shown in FIG. At this time, the confirmation guidance 230 displays a message corresponding to the first tax rate “Are you sure the tax rate of the product 6 is 8%?”. Further, the confirmation guidance 230 has a “confirm” button 231 and a “return” button 233.

When the “confirm” button 231 is pressed, the tax rate specified in the specification guidance 220 is fixed and the tax rate is input to the electronic cash register 1.
When the “return” button 233 is pressed, the tax rate specified in the specification guidance 220 is not fixed and the process returns to the specification guidance 220.

When the “Tax 2” button 223 is pressed in the designation guidance 220 of FIG. 12, the confirmation guidance 230 indicates that “the tax rate of the product 6 corresponding to the second tax rate is 10%, as shown in FIG. Is displayed.
In the designation guidance 220 of FIG. 12, when the “select every time” button 225 is pressed, as shown in FIG. 15, the confirmation guidance 230 has a message “Are you sure you want to select the tax rate for the product 6 every time?”. Is displayed.
In other respects, the confirmation guidance 230 in FIGS. 14 and 15 is the same as that in FIG.

<< Designated Guidance: Second Example >>
A second example of the designation guidance will be described with reference to FIGS.
In the first example of the designation guidance, tax 1, tax 2, or selection every time is displayed together on one screen. On the other hand, in the second example of the designation guidance, among the tax 1, tax 2, and each time selection, the most frequently used one is displayed first, and the rest is displayed on the next screen.

  As shown in FIG. 16, the designation guidance 240 is displayed in a pop-up on the sales registration screen 210. For example, when the tax rate of “product 6” is designated, the designation guidance 240 displays a message “Are you sure the tax rate of product 6 is 10%?”. Further, the designation guidance 240 has a “Yes” button 241 indicating use of the tax 2 and a “No” button 243 indicating use other than the tax 2.

  When the “Yes” button 241 is pressed, the confirmation guidance 230 of FIG. 14 is displayed. The confirmation guidance 230 is the same as the first example except that when the “return” button 233 is pressed, the confirmation guidance 230 is returned to.

  When the “No” button 241 is pressed, a designation guidance 250 is popped up on the sales registration screen 210 as shown in FIG. For example, when the tax rate of “product 6” is designated, a message “Please specify the tax rate of product 6” is displayed in the designation guidance 250. The designation guidance 250 includes a “tax 1” button 251 indicating use of tax 1 and a “select every time” button 253 indicating use of selection of a tax rate each time.

When the “tax 1” button 251 is pressed, the confirmation guidance 230 of FIG. 13 is displayed.
The confirmation guidance 230 is the same as the first example except that when the “return” button 233 is pressed, the confirmation guidance 230 returns to the designation guidance 250.
When the “select every time” button 253 is pressed, the confirmation guidance 230 of FIG. 15 is displayed. The confirmation guidance 230 is the same as the first example except that when the “return” button 233 is pressed, the confirmation guidance 230 returns to the designation guidance 250.

<Variable substitution process>
Referring to FIG. 18, the variable substitution process in steps S12 and S22 of FIG. 10 will be described (see FIG. 2 as appropriate).
This variable substitution process is a process for substituting a tax rate and written characters corresponding to either tax 1 or tax 2 into variables used in the sales registration process in accordance with the product master management 111.

  The CPU 100 determines whether or not the designated product is recorded when tax 1 is used in the product master management 111. That is, the CPU 100 determines whether or not the tax use type of the designated product is “1” in the product master management 111 (step S40).

  If it is not recorded that tax 1 is used (No in step S40), the CPU 100 determines whether or not tax 2 is recorded in the product master management 111 for the specified product. That is, the CPU 100 determines whether or not the tax use type of the designated product is “2” in the product master management 111 (step S41).

If it is not recorded that the tax 2 is used (No in step S41), the CPU 100 displays the designation guidance 220A of FIG. 19 on the input display unit 11 and inquires of the store clerk whether to use the tax 1 or the tax 2 The tax rate to be used is input (step S42).
As shown in FIG. 19, the designation guidance 220A is obtained by deleting the “select every time” button 225 from the designation guidance 220 in FIG.

The CPU 100 determines whether or not an input is made when tax 1 is used (step S43).
When it is input that tax 1 is used (Yes in step S43), or when it is recorded that tax 1 is used (Yes in step S40), the CPU 100 displays the tax rate and the written characters of the tax 1 product master 110b. Then, it is substituted into a variable used in the sales registration process (step S44), and the process is terminated.

  If the tax 1 is not used (No in step S43), or if the tax 2 is recorded (Yes in step S41), the CPU 100 displays the tax rate and the written characters of the tax 2 product master 110c, It substitutes for the variable used by sales registration processing (step S45), and ends processing.

When the tax rate of the designated product is changed by the processing of steps S42 to S45, the tax rate assigned to the product is updated with the changed tax rate.
In addition, in the process of steps S42 to S45, when tax 1 is assigned to the designated product according to the change operation, tax 2 is assigned, whereas when tax 2 is assigned to the designated product. Allocate tax 1.

  As described above, the electronic cash register 1 in the first embodiment can select different tax rates without setting the tax rate for each product in advance, and can select a plurality of tax rates at the time of the initial sale of the product. Can reduce the labor required to set

(Second Embodiment)
<Configuration of electronic cash register>
With reference to FIG. 20, the difference of the configuration of the electronic cash register 1B according to the second embodiment from the first embodiment will be described.
In 1st Embodiment, it demonstrated as using the goods master management 111 (FIG. 2). The second embodiment is different from the first embodiment in that the product master management 111 is not used. Therefore, in the second embodiment, the product is deleted from the unused one from the tax 1 product master 110Bb and the tax 2 product master 110Bc.

As shown in FIG. 20, the main body 10B of the electronic cash register 1B includes a CPU 100B, a RAM 101, a main storage device 102B, a communication control unit 103, and a storage medium read / write unit 104.
The CPU 100B controls the entire electronic cash register 1B by executing a control program 113 on the main storage device 102B.
The main storage device 102B records a product master 110a, a tax 1 product master 110Bb, a tax 2 product master 110Bc, product sales information 112, a control program 113, and the like.

<< Product Master >>
The tax 1 product master 110Bb and the tax 2 product master 110Bc will be described with reference to FIGS.
21 and 22 show a state after selecting whether to use the tax 1 or the tax 2 in the sales process (FIG. 22) of the products 2 to 4. That is, the products 2 to 4 exist only in one of the tax 1 product master 110Bb and the tax 2 product master 110Bc.

  As shown in FIG. 21, the tax 1 merchandise master 110Bb is similar to the tax 1 merchandise master 110b shown in FIG. 5 in the form of “product code”, “product name”, “tax rate”, and “notation characters”. Composed. Here, in the tax 1 product master 110Bb, the information of the product 2 is deleted. That is, since the product 2 does not exist in the tax 1 product master 110Bb, it indicates that the tax 2 product master 110Bc is used.

  As shown in FIG. 22, the product master for tax 2 110Bc includes “product code”, “product name”, “tax rate”, and “notation character” in the same manner as the product master for tax 2 110c in FIG. Composed. Here, in the tax 2 product master 110Bc, the information on the products 3 and 4 is deleted. That is, since the products 3 and 4 do not exist in the tax 2 product master 110Bc, the tax 1 product master 110Bb is used.

<Product sales processing>
The merchandise sales process will be described with reference to FIG. 23 (see FIG. 2 as appropriate).
The store clerk operates the input display unit 11 to specify a product to be sold with a product code or the like (step S50).
The CPU 100B determines whether or not the designated product is in both the tax 1 product master 110Bb and the tax 2 product master 110Bc (step S51).

When the designated product exists in both (Yes in step S51), the CPU 100B displays the designation guidance 220A of FIG. 19 on the input display unit 11, inquires the store clerk whether to use tax 1 or tax 2, and uses it. The tax rate to be entered is input (step S52).
The CPU 100B determines whether to use tax 1 or tax 2 (step S53).

When using tax 1 (tax 1 in step S53), the CPU 100B deletes the designated product from the tax 2 product master 110Bc (step S54).
The CPU 100B substitutes the tax rate and the written characters of the tax 1 product master 110Bb into variables used in the sales registration process (step S55).

  The CPU 100B performs sales registration processing for the product specified in step S50 using the tax rate and the written characters assigned to the variables (step S56), and ends the processing.

When using tax 2 (tax 2 in step S53), the CPU 100B deletes the designated product from the tax 1 product master 110Bb (step S57).
The CPU 100B substitutes the tax rate and written characters of the tax 2 commodity master 110Bc into variables used in the sales registration process (step S58), and proceeds to the process of step S56.

When there is no designated product in both (No in step S51), the CPU 100B determines whether or not the designated product is in the tax 1 product master 110Bb (step S59).
When the designated product is in the tax 1 product master 110Bb (Yes in step S59), the CPU 100B substitutes the tax rate and the written characters of the tax 1 product master 110Bb into variables used in the sales registration process (step S60). The process proceeds to step S56.

When the designated product is not in the tax 1 product master 110Bb (No in step S59), the CPU 100 determines whether or not the designated product is in the tax 2 product master 110Bc (step S61).
When the designated product is in the tax 2 product master 110Bc (Yes in step S61), the CPU 100B substitutes the tax rate and the written characters of the tax 2 product master 110Bc into variables used in the sales registration process (step S62). The process proceeds to step S56.

  When the designated product is not in the tax 2 product master 110Bc (No in step S61), the CPU 100B performs a conventional process when there is no designated product (step S63), and ends the process.

  As described above, the electronic cash register 1B in the second embodiment has the same effect as the electronic cash register 1 of FIG. Furthermore, the electronic cash register 1B does not need to store the product master management 111 of FIG. 7, and can realize a simple configuration.

(Modification)
The present invention is not limited to the above embodiment, and can be modified without departing from the spirit of the present invention.

  In the first embodiment, since the merchandise master is copied to the tax 1 merchandise master and the tax 2 merchandise master, there are a total of three merchandise masters. However, the present invention is not limited to this. For example, a product master may be used as a tax 1 product master, a tax 2 product master may be newly prepared, and a total of two product masters may exist.

  Moreover, although the product master, the product master for tax 1 and the product master for tax 2 hold the tax rate and the written characters for each product, they may be linked to other files and data having relations. In the example of FIG. 24, the product master 110a is linked to the tax table 114 by the “reference tax table”. Specifically, the numerical value in parentheses in the “reference tax table” of the product master 110 a corresponds to “record No.” in the tax table 114. Therefore, commodity 1 is taxed at a tax rate of 10%. Product 2 is taxed at a tax rate of 8%.

  In the first embodiment, information on a product that has never been specified in the product master management is not included, but a tax usage type of a product that has never been specified is determined in advance, and the product master management is preliminarily determined. It may be recorded. In this case, in the tax rate selection process of FIG. 11, in the process of step S <b> 11, it may be determined whether there is a tax use type product that has never been specified in the product master management.
