Description

Description: FIELD OF THE INVENTION The present invention relates to an electronic cash register, and more specifically,
The present invention relates to a new electronic cash register that can obtain a taxable amount such as a consumption tax when discounting.

2. Description of the Related Art In a typical prior art, the registration receipt shown in FIG. 4 is configured to be obtained by printing it on a recording sheet. When entering the transaction of goods, when the external tax department is 1,000 yen, the internal tax department is 2,000 yen and the tax exempt department is 3,000 yen, the subtotal is 6,000 yen. At this time, if a key operation is performed for discounting as indicated by reference numeral a1 and the discount amount is 100 yen, the subtotal is 5,900 yen. Reference mark b1
As shown in, the taxable amount, which is the amount subject to external tax, is 900 = 1,000-100 ... (1). Therefore, the tax, which is a consumption tax of 3% of the taxable amount, is 27 yen. As indicated by the reference mark c1,
The total tax, which is the amount subject to internal tax, is calculated as 1,900 yen.

1,900 = 2,000-100 (2) At this time, the consumption tax is 55 yen. Therefore, cash of 5,927 yen to be paid is calculated as shown in the third equation.

5,970 = 900 + 27 + 1,900 + 3,000 + 100 (3) Therefore, when the amounts of the registered products are mixed in both the external tax method and the internal tax method, in the above-mentioned prior art, both the external tax and the internal tax subject subtotals are both included. Discounted from. Therefore, in the sales report, the respective amounts of the tax-excluded subtotal and the tax-excluded subtotal are printed as amounts obtained by subtracting the discount amount. Therefore, the inconsistent amount of this double discount,
It is added to the tax exempt subtotal and cash is calculated based on the third formula as described above. There is a demand for avoiding such a contradiction in the sales report and performing arithmetic processing that makes sense without causing a contradiction.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention An object of the present invention is, when a transaction amount of a commodity or the like is mixed between an external tax method and an internal tax method, when a discount is made, the apportionment of the discount is successfully performed. It is to provide an electronic cash register that can be performed.

Means for Solving the Problems The present invention provides a means for inputting a first amount of money for a product for which a predetermined percentage of an external tax is taxed, a means for inputting a second amount of money for a product including an internal tax amount, and a discount amount. A means for inputting, a means for obtaining a proportional distribution ratio of the discount amount to the sum of the first input amount and the second input amount, and a prorated amount that is the product of the first and second input amounts and the proportional distribution ratio. , An electronic monetary amount characterized by including a prorated amount calculating means for respectively calculating a taxable amount by subtracting a prorated amount corresponding to each input amount from each of the first and second input amounts. It is a registered machine.

Operation According to the present invention, the sum of the first amount of the tax exemption method in which a predetermined percentage of the tax exemption is levied and the second amount of the tax exemption method including the tax exemption amount is added, and the sum is calculated. Calculate the proration rate, which is the ratio of the discounted amount. Based on this proportional division rate, the proportional division amount corresponding to each of the first and second amounts is obtained. First
And the taxable amount is obtained by subtracting the prorated amounts corresponding to the respective input amounts from the second input amounts. In this way, even if the amount of each of the products of the external tax and the internal tax method is mixed, the price is reduced by the same percentage at the same time when discounting, so there is no contradiction and it makes sense. You will be able to request a successful taxable amount.

Embodiment FIG. 1 is an overall block diagram of an embodiment of the present invention. The key input means 1 of the electronic cash register is a numeric key 0 to 9, a product specification key 3 operated to specify a product, a subtotal key 4 and a key 5 operated when discounting. And so on. The signal input from the key input means 1 is given to a processing circuit 6 realized by a microcomputer or the like to perform calculation, and the calculation result is displayed by a visual display means 7 such as a cathode conduit. It is printed by the printer 9 on the recording paper 8 such as a sales report and a sales receipt.

FIG. 2 is a flow chart for explaining the operation of the embodiment shown in FIG. By inputting the specified product from the product specification key 3, the processing circuit 6 determines the unit price and the amount of the input product, and further whether the product is the external tax system or the internal tax system. .
Then, it is determined in step n1 whether or not the discount has been registered. In order to input the discount amount, the subtotal key 4 in the key input means 1 is operated, the discount amount is then operated and input by the numeral keys 2, and then the key 5 representing the discount is operated. As a result, the process proceeds from step n1 to step n2, and the discount amount is set as D. In step n3, a proration rate r, which is the ratio of the discount amount D to the sum of the subtotal A of the external tax department, the subtotal D of the internal tax department, and the subtotal C of the tax-exempt department, which is calculated by the processing circuit 6, is calculated. .

In step n4, the prorated amount A · r, which is the product of the subtotal A of the external tax department and the proration rate r, is obtained, and this prorated amount A · r is subtracted from the subtotal of the external tax department to obtain the external tax subtotal. Calculate the taxable amount A1.

A1 = A−A · r (5) In step n5, the amount E of external tax is calculated and obtained. E = A1 × 0.03… (6) In step n6, the internal tax that is the taxable amount of the internal tax department subtotal
B1 is calculated as shown in equation 7.

B1 = B−B · r (7) Here, the proportional division rate of the internal tax method is the product of the subtotal B of the internal tax department and the proportional division rate r.

In step n7, the amount F of tax is calculated.

Further, in this embodiment, the tax exemption subtotal C1 is obtained by discounting the subtotal C of the tax exemption department at the same proration rate.

C1 = C−C · r (9) With this, the total amount G is calculated.

G = A + B + C-D + E (10) In step n10, the subtotal values A1, B1, C1 that are taxable amounts
Then, the total value G and the discount amount D are printed by the printer 9 and visually displayed by the display means 7.
In this way, even if the amounts of the products of the external tax, the internal tax and the tax exempt method are mixed, the taxable amount of each of the external tax and the internal tax is calculated by discounting at the same proportion, and You can ask for tax-exempt subtotals, and thus make reasonable and successful discounts without creating contradictions.

FIG. 3 shows an example of a registration receipt printed by a more specific printer 9. When the subtotal A of the tax department is 1,000 yen, the subtotal B of the internal tax department is 2,000 yen, and the subtotal C of the tax-exempt department is 3,000 yen, when the subtotal is 6,000 yen and the discount is 100 yen, The subtotal after the discount is
It is 5,900 yen. Therefore, the proportional division ratio r is expressed by the eleventh formula.

r = -100 ÷ 6,000 = -0.01666666 (11) Round off the proration rate shown by this 11th formula to determine r = -1.6667%.

Therefore, the taxable amount of the foreign tax department, that is, the total taxable amount of 983
A circle is calculated and printed as indicated by reference sign a. This calculation is obtained as shown in Equation 12.

1,000-1,000 x 1.6667% = 983 (12) Here, the tax of the foreign tax department is 29 yen.

The taxable amount of the internal tax department is 1,96 as indicated by the reference sign b.
It is 7 yen, which can be obtained as shown in Equation 13.

2,000-2,000 × 1.6667% = 1,967 (13) At this time, the tax amount is 57 yen.

The total tax exemption of ¥ 2,950 can be calculated from Equation 14.

3,000-3,000 x 1.6667% = 2.950 (14) With this, the total transaction amount of cash of 5,929 yen can be calculated and obtained.

In the present invention, the products of the tax exemption department may not exist.

As described above, according to the present invention, even if the amounts of the external tax method and the internal tax method are mixed, the discount amount is deducted from the respective amounts at the same ratio, that is, the same proration rate, and the taxable object. The amount can be calculated, and the taxable amount can be calculated successfully.
