Abstract

PURPOSE:To improve the operability of registration of exemption object persons by discriminating tax-free commodities and taxable commodities by a tax discriminating means and subtotaling them independently of each other to calculate the amount of tax and the total amount of money after tax. CONSTITUTION:At the time of registering sale data of a commodity, whose sale is registered, in a storage part by the commodity register operation, the amount of sale of this commodity is accumulated in taxable commodity subtotal memories 41 and 42 when the commodity is taxable, but the amount of sale of the commodity is accumulated in a tax-free commodity subtotal memory 43 when it is tax-free. When the closing operation is performed in this state, the amount of tax, the taxable amount of money, and the tax-free amount of money are added to calculate the total amount of money before tax. Thus, the total amount of money after tax is momently calculated with an easy key operation though selling commodities are registered without distinction between taxable commodities and tax-free commodities, and the operability of registration of exemption object persons is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a product sales data processing device such as an electronic cash register or an electronic price scale.

[Prior Art] A product sales data processing device applicable in countries or regions that adopt the direct tax method in which the customer who purchases the product pays the excise tax levied on the product directly at a store, etc.
The following are known (patent application 1076-1987)
(See No. 33). In other words, a tax flag indicating whether the product with the code is a taxable product is provided in the product file that cumulatively totals the sales of each product for each code, and a total amount memory that stores the cumulative sales amount of products sold to - customers. and a taxable amount total memory for storing cumulatively the sales amount of taxable products among the sold products.

Further, the keyboard is provided with a tax key and a non-tax key.

Then, it is determined whether the product registered for sale by the product registration operation is a taxable product or not according to the taxable key or non-taxable key if the key was inputted immediately before, or according to the key if the taxable key or nontaxable key was inputted immediately before. It follows the tax flag corresponding to the applicable code in the product file.

Therefore, if the customer is a tax-exempt person, such as a foreigner, the store must input the tax-exempt key every time it registers a product. By doing this, even if the product is taxable, it will be treated as non-taxable, and the total amount calculated by the registration operation will be the amount excluding tax.

[Problems to be Solved by the Invention] However, such conventional devices are also insufficient in the following points. In other words, the tax exemption key must be input each time a product purchased by a tax exempt person is registered, resulting in poor operability.

Furthermore, if a tax exempt person forgets to input the tax exemption key when registering a taxable product purchased, the product will be treated as a taxable product, and the tax amount for the taxable amount will be included in the total depending on the input operation.

Therefore, the present invention makes it possible to instantly calculate the total price excluding tax with a simple key operation even when registering sales products without distinguishing between taxable and non-taxable products, thereby improving the ease of registration for tax-exempt persons. The purpose of this invention is to provide a product sales data processing device that can be improved.

[Means for Solving Problem R] The present invention is a product sales system in which sales data of products registered for sale through a product registration operation is registered in a storage unit, and a receipt with a total printed thereon is issued in response to a closing operation. The data processing device includes a tax determination means for determining whether or not a product registered for sale through a product registration operation is a taxable product, and stores cumulative sales amounts for one customer of products determined to be non-taxable products by the tax determination means. A non-taxable subtotal memory, a taxable subtotal memory that stores cumulative sales amounts for each customer of products determined to be taxable products by this tax determination means, and a tax amount that calculates the tax amount for the taxable amount cumulatively stored in this taxable subtotal memory. a calculation means, a tax exemption key, a judgment means for determining whether or not the tax exemption key is input when a closing operation is performed, and when the judgment means determines that the tax exemption key has not been input, the tax exempt amount in the tax exemption subtotal memory 1 taxable subtotal memory The total amount including tax is calculated based on the taxable amount in 1 and the tax amount calculated by the tax amount calculation means, and when it is determined that the tax exemption key has been entered, the total amount excluding tax is calculated based on the taxable amount 1 taxable amount and the tax amount. and a means for calculating the total amount.

[Operation] With the present invention configured as described above, if the product registered for sale by the product registration operation is a taxable product, the sales amount of the product is accumulated in the taxable subtotal memory, and if the product is a nontaxable product, the product is sales amount is accumulated in tax-exempt subtotal memory. In this state, when the closing operation is performed, if the visibility is external tax, the taxable amount in the taxable subtotal memory is multiplied by the tax rate to obtain the tax amount, and the tax amount and taxable amount are combined in the nontaxable subtotal memory. The tax-exempt amount is added to calculate the total amount including tax. In addition, if the visibility is inclusive tax, the tax amount is already included in the taxable amount in the taxable subtotal memory, so the taxable amount and the taxable amount in the nontaxable subtotal memory are added to calculate the total tax-inclusive amount. is calculated.

On the other hand, when the closing operation is performed after the tax exemption key is input, if the visibility is inclusive tax, the taxable amount in the tax subtotal memory is multiplied by the tax rate to obtain the tax amount, and the taxable amount and non-taxable amount are The tax amount is subtracted from the amount added to the tax-exempt amount in the subtotal memory to calculate the total amount excluding tax. In addition, if the visibility is external tax, the taxable amount in the taxable subtotal memory does not include the tax amount, so the taxable amount and the taxable amount in the nontaxable subtotal memory are added to obtain the total excluding tax. is calculated.

〔Example〕

Hereinafter, an embodiment in which the present invention is applied to an electronic fare scale will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the electronic fare scale of this embodiment. In the figure, CPU (central processing unit) 1
constitutes the main body of the control section, and is connected via the path line 2 to each storage section including a ROM 3 in which control program data etc. are set, a RAM 4 in which various memories used for data processing are formed, a product number file 5, and a keyboard controller. 6
, the display controller 7 and the print controller 8 are operated.

In addition, the CPUI takes in the current date and time data from the clock circuit 9 at the appropriate time, and also receives the current date and time data from the A/D converter 10.
A count value corresponding to the weight value measured by the weighing section 11 is taken in from the weighing section 11.

In the product number file 5, as shown in Figure 2, the product name, unit price per unit weight, tax flag, etc. are set corresponding to the product number assigned to each product, as well as a cumulative area for weight and amount. is provided.

Here, the tax flag is information to indicate whether or not the product with the corresponding product number is a taxable product. For example, flag [00] indicates a non-taxable product, flag [01] indicates an internal tax. It is assumed that the flag [10] indicates a taxable product and the flag [10] indicates a taxable product.

As shown in FIG. 3, the keyboard controller 6 includes number keys Kl for "0" to "9", 2 for the product number key for specifying the product number, 3 for the addition key for instructing product registration, and 3 for the cash transaction key. A keyboard 12 is connected with various function keys such as 4 as a deposit/account key for instructing closing of registration, and 5 as a tax exemption key.

A display 13 is connected to the display controller 7 and is capable of displaying the product name, unit price/weight, price, etc.

Connected to the print controller 8 is a printer 14 that prints sales data, totals, etc. on receipt paper and issues a receipt.

In addition to a calculation work memory, a display buffer, a print buffer, etc., the RAM 4 includes a tax subtotal area 41. as shown in FIG. External tax subtotal area 42. Tax-exempt subtotal area 43 and product number.

A customer table 40 consisting of a plurality of registered data areas 44 that store registered data such as unit price, weight, and amount; a tax rate memory 45 that stores tax rates preset by predetermined key operations; A flag memory 46 for a tax exemption flag is formed. Here, the internal tax subtotal area 41 of the customer table 40 stores the cumulative sales amount of internal tax products for one customer, and the external tax subtotal area 42 stores the cumulative sales amount of external tax products for one customer. The tax-exempt subtotal area 43 stores the cumulative sales amount of tax-exempt products for one customer. Further, the tax rate in the tax rate memory 45 can be changed at any time by key operations on the keyboard 12 in a setting mode for setting PLO and the like.

Thus, the CPUI is programmed to process a bill for a single customer according to the flowchart of FIG. That is, when the product number of a registered product is entered as ST (step) 1 using 1 in the number key and 2 in the product number key on the keyboard 12, the product with the product name, unit price, and tax flag corresponding to the product number is input from the product number file 5. Read data. In this state, a count value is taken in from the A/D converter 10 and converted into a weight value of the registered product weighed by the weighing section 11. Then, the sales amount is calculated by multiplying this weight value by the read unit price, and the product name is calculated.

The unit price 9 and the weight value as well as the sales amount are displayed on the display 13.

Thereafter, in ST2, a key input from the keyboard 12 is waited for. Here, when 3 is input to the addition key, the state of the tax flag of the read product data is checked (tax determination means)
. Then, when the tax flag is [10], the product with the product number is an included tax product, so the sales amount is added to the included tax subtotal area 41 of the customer table 40. Tax flag is [01
], the product with the product number is a tax-excluded product, so the sales amount is added to the subtotal tax area 42 of the customer table 40. When the tax flag is [00], the product with the corresponding product number is a tax-exempt product, so the tax-exempt subtotal area 4 of the customer table 4o
Add the sales amount to 3.

Thereafter, the registration data of the product number, unit price, weight, and amount are stored in the vacant registration data area 44 of the customer table 40, and the process returns to Sr1.

If there is a key input in Sr1 and the person's key is 5 for the tax exemption key, the tax exemption flag is set in the flag memory 40 and the process returns to Sr1.

When there is a key input in Sr1 and the input key is 4 in the deposit/account key, the registered data in the registered data area 44 in the customer table 40 is sequentially read out in the order in which they are stored, sent to the print controller 8, and sent to the printer. 14 to print on the receipt. Next, flag memory 4 is used as Sr1.
6, it is determined whether the tax exemption flag is set. If the tax exemption flag is reset here, the customer is a taxable person, so the taxable amount stored in the external tax subtotal area 42 is multiplied by the tax rate in the tax rate memory 45 to obtain the external tax amount (tax amount calculation means) . Then, the taxable amount in the internal tax subtotal area 41 and the taxable amount in the non-taxable subtotal area 43 are added to the amount obtained by adding the tax amount to the taxable amount in the external tax subtotal area 42.
Calculate the total including tax by adding the tax-exempt subtotals in (
total amount calculation method). Next, the total amount including tax and the tax amount are printed on a receipt, the receipt is issued, and this process is completed.

On the other hand, if the tax exemption flag is set in Sr1, the customer is a tax exempt person, so the tax amount for the taxable amount stored in the internal tax subtotal area 41 is calculated based on the tax rate in the tax rate memory 45 ( tax amount calculation method). Then, add the taxable amount in the external tax subtotal area 42 and the non-taxable subtotal in the non-taxable subtotal area 43 to the amount obtained by subtracting the tax amount from the taxable amount in the above-mentioned internal tax subtotal area 41 to make a total excluding tax. (total amount calculation means). Next, this total amount excluding tax is printed on a receipt, the receipt is issued, and this process is completed.

The customer table 40 is cleared after issuing a receipt by inputting 4 in the deposit/total key, or before registering the first product for one customer by inputting 3 in the addition key.

In this embodiment configured as described above, when a product for sale is weighed in the weighing section 11 and the product number of the product for sale is specified using the number key 1 and the product number key 2, the weight value and unit price are calculated. The sales amount is calculated from the amount and displayed on the display 13. In this state, when the user inputs 3 on the addition key to instruct the registration of the sales product, the registration data of the product number, unit price, ii quantity, and price are stored in the registration data area 44 of the customer table 40. In addition, the visibility is determined based on the tax flag of the sales product, and if it is an internal tax product, it is displayed in the internal tax subtotal area 41, and if it is an external tax product, it is displayed in the external tax subtotal area 4.
2, if the product is tax exempt, the sales amount is added to the tax exempt subtotal area 43.

After that, if 4 is entered in the deposit/cash key without 5 being entered in the tax exemption key, the tax amount for the taxable amount in the external tax subtotal area 42 is calculated, and the total amount including tax including this tax amount is calculated. A receipt is issued on which the total price including tax and the tax amount are printed together with the registration data of each sold product in the registration data area 44.

On the other hand, if 5 is entered in the tax exemption key and then 4 is entered in the deposit/cash key, the tax amount for the taxable amount in the internal tax subtotal area 41 is calculated, and the tax amount from which this tax amount is subtracted is calculated. The total price excluding tax is calculated, and a receipt is issued on which the total price excluding tax is printed together with the registration data of each sold product in the registration data area 44.

FIG. 6 is an example of a receipt issued when all registered products are tax-exempt products (tax flag -10) and no tax exemption key is entered. In this case, since the taxable amount in the internal tax subtotal area 41 already includes the tax amount, the taxable amount [1054 yen] becomes the customer's total amount.

FIG. 7 is an example of a receipt issued when all registered products are tax-exempt products (tax flag -10) and the tax-exempt key is input. In this case, the taxable amount in the internal tax subtotal area 41 [1054 yen] is reduced to the internal tax amount [30 yen: the tax rate is 3%.
The non-taxable amount [1024 yen] after subtracting the tax-exempt amount [1024 yen] becomes the customer's total amount.

FIG. 8 is an example of a receipt issued when all registered products are tax-exempt products (tax flag -01) and no tax exemption key is input. In this case, the taxable amount in the external tax subtotal area 42 does not include the tax amount, so the taxable amount [
1,054 yen] and the tax amount [31 yen: if the tax rate is 3%] is added to the customer's total amount [1,085 yen].

FIG. 9 is an example of a receipt issued when all registered products are tax-exempt products (tax flag -01) and the tax-exempt key is input. In this case, the taxable amount [1054 yen] in the external tax subtotal area 42 becomes the customer's total amount.

According to this embodiment, for example, for a tax exempt person such as a foreigner, by simply inputting 5 into the tax exemption key before closing the customer's registration, the tax amount will be deducted from the total amount at the closing operation. The total amount excluding tax can be calculated instantly. Therefore, it is no longer necessary to input the tax exemption key every time a product is registered for a tax exempt person as in the past, so the operation is simplified, there are no operational errors, and the operability is improved.

In the above embodiment, a case is shown in which both visibility ranges for an internal tax product and an external tax product are handled, but if only one of the visibility ranges is handled, the subtotal area for the other visibility may be omitted. Furthermore, although the above embodiments show the case where the present invention is applied to an electronic fare scale, it goes without saying that it can also be applied to a product sales data processing device such as an electronic cash register or a POS (point of sale) system. That's true.

[Effects of the Invention] As detailed above, according to the present invention, even if sales products are registered without distinguishing between taxable products and non-taxable products, the total price excluding tax can be instantly calculated with a simple key operation. It is possible to provide a product sales data processing device that is capable of calculating the amount of tax and improves the operability of registration for tax-exempt persons.
