Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic register having a function of calculating the amount of tax on the total transaction amount using a preset arithmetic expression.

[Prior Art] Generally, there are various calculation formulas for calculating the tax amount. For example, with the Add On Tax (AOT) method, if the tax amount is 15% and the customer purchases a product that costs 200 yen, a tax amount of 30 yen will be added and the amount paid by the customer will be reduced.
230 yen, and Value Added Tax (VAT)
Under this method, for a product with a tax rate of 15% and a payment amount of 200 yen, 174 yen will be the tax-excluded price and 26 yen will be the tax amount. By the way, in conventional electronic registers that calculate tax amounts, when a transaction-specific key is operated at the end of registration for one customer, the tax amount calculated is based on one type of method, such as the AOT method or the VAT method. The tax rate is also determined based on a preset value.

[Problems to be Solved by the Invention] Therefore, when registering products with different tax rates even though they are based on the same calculation formula, it is necessary to change the tax rate set according to the tax rate of the product. Additionally, if there are products for which the tax amount is calculated using each of the AOT and VAT methods, it will not be possible to register them as is, and the operator will have to use another calculation device to calculate the tax amount. , there was a risk that the registration operation would take a long time and could lead to incorrect operations.

This is thought to be due to the fact that with conventional electronic registers, the calculation formula and tax rate used to calculate the tax amount are limited to one type of calculation formula and tax rate set in the electronic register at that time. It will be done.

An object of the present invention is to make it possible to calculate the tax amount for each registered product using an arbitrary calculation formula and tax rate with only a few setting operations.

[Means to solve the problem] The means of this invention are as follows.

A classification designation key that specifies the input of monetary data by classification (such as the departmental key of the input section 6), and an AOT that is operated in conjunction with the operation of the classification designation key when the monetary data to be input is taxable data. A first taxation key that specifies the formula for the VAT method, and a second taxation key that specifies the formula for the VAT method (input section 6
T/S ₁ , T/S ₂ keys, etc.) and this first
taxation data storage means (m1, m2 of memory 5, etc. ), a setting means (input section 6, etc.) for setting a tax rate corresponding to the first taxation key and the second taxation key, and each taxation data stored in the taxation data storage means when the transaction-specific key is operated. and calculation means (CPU 1, etc., step S ₈ ) for calculating the tax amount related to the cumulative value based on the corresponding tax rate and according to the corresponding calculation formula.

Note that the information in parentheses has been added for reference in order to clarify how each of the above-mentioned means is embodied in the embodiment.

[Effect] The operation of the means of this invention is as follows.

Corresponding to each of the first taxation key that specifies the calculation formula of the AOT method and the second taxation key that specifies the calculation formula of the VAT method by the presetting means,
Set tax rates. When the input of amount data by category is specified using the category specification key, if this amount data is taxable data, the first taxation key or the second taxation key is
operate the taxation key. Then, this amount data is accumulated and stored in tax data storage means provided corresponding to each of the first tax key and the second tax key. When the transaction-specific key is operated, the calculation means calculates the tax amount regarding the cumulative value of each taxation data stored in the taxation data storage means, based on the corresponding tax rate and according to the corresponding calculation formula.

Therefore, with only a few setting operations, the tax amount can be calculated for each registered product using an arbitrary calculation formula and tax rate.

[Example] An example will be described below based on FIGS. 1 to 6.

FIG. 1 shows a schematic system configuration diagram of an electronic register, and reference numeral 1 is a CPU, and this CPU 1 includes a Z

is connected to each of the control units 2 and 2 via the address bus AB.
Address signals are output to 3, 4 and memory 5. Furthermore, the CPU 1 inputs data from the input buffer IN provided in the input control section 2 via the data bus DB, and also inputs data from the display buffer DI provided in the display control section 3 and the data provided in the print control section 4. Data is output to each print buffer PR, and data is exchanged with the memory 5.

The input control section 2 outputs a timing signal KP to an input section 6, and when a key operation is performed in the input section 6, the timing signal KP is selected according to the operation key, and as a key input signal KI, Input to input buffer IN. The input section 6 includes:
It is equipped with numeric keys, department keys, transaction keys such as credit sales key, credit sales key, cash/deposit key, and mode switches for specifying each mode such as ``setting'' and ``registration.'' . In addition, the input unit 6 is provided with taxation keys T/S ₁ and T/S ₂ that are operated when inputting taxation data for taxing the purchased products.

Further, the display control section 3 receives a digit signal.
A segment signal SG obtained by decoding the data of the DG and display buffer DI is output to the display section 7, and the amount data and the like are displayed on the display section 7. Further, a print position signal TP of a print drum (not shown) provided in the print unit 8 is inputted to the print control unit 4, and this print position signal TP and a print buffer PR are inputted to the print control unit 4.
A print drive signal HD generated by matching the data in the print section 8 is sent to the print section 8. Then, the printing unit 8 prints amount data and the like on the recording paper according to the print drive signal HD.

The memory 5 is provided with tax memories T1 and T2 as shown in FIG. The tax memories T1 and T2 store the tax keys T/S 1 and T/S ₁ , respectively.
It corresponds to T/S ₂ , and there is an identification code TI1, which is used to identify whether the taxation key is used in the AOT or VAT calculation formula, respectively.
TI2, tax rate data t ₁ , t ₂ , and total tax data m 1 , m 2 inputted by each tax key operation.
is memorized. In addition, the memory 5 is provided with storage areas M _TA , M _TX , M _Z, etc. in which the taxable amount, tax amount, and cash sales totals are stored.

Next, the operation of this invention will be explained. Now, set the mode switch to "Settings" mode,
Taxation key T/S ₁ and corresponding identification code TI1
'10' as AOT code and tax rate data _t1
Enter %. Further, a VAT code is inputted into the identification code TI2 corresponding to the taxation key T/ _S2 , and "15"% is inputted as the tax rate data _t2 . Next, set the mode switch to "registration" mode, and select the tax key T/S ₂ , number key □5□0□0, and department key as shown in Figure 3.
01, the product name "WINE", the symbol "T ₂ " indicating the operated tax key T/S ₂ , and the tax amount "5.00" are printed on the recording paper as shown in Figure 4. , and at the same time tax memory T
Input tax data is accumulated in 1. In exactly the same way, if you enter SALAD and STEAK as AOT products using the taxation key T/S ₁ , and enter BEER as a VAT product using the taxation key T/S ₂ , the corresponding print on the recording paper will be displayed. After that, when the cash/deposit key CA is operated, the operation according to the flow shown in FIG. 5 is executed.

That is, in executing step _S1 , each data stored in the tax memory T1 is read out. Next, the process moves to step _S2 , where it is determined whether the identification code T1 read from the tax memory T1 or T2 is an AOT code or a VAT code, and if it is an AOT code, the process proceeds to step _S3 . Move. In executing step _S3 , the read tax data total m is written to the TA register of CPU1, and then step _S5
Move to. If the code is identified as a VAT code in step _S2 , the process moves to step _S4 , where the total tax data m is divided by 1 + tax rate data x 0.01, that is, the calculation m/1 + 0.0t is executed to calculate the tax-exempt price. It is calculated and written to the TA register, after which the process moves to step _S5 .

In the execution of step _S5 , TA accumulation is performed in which the data written in the TA register is accumulated in the storage area _MTA of the memory 5 as taxable amount data. Next, proceed to step _S6 , and the CPU
TA addition is performed in which the taxable amount data of the TA register is added to the Z register of 1. Next, the process moves to step _S7 , where the taxable amount data in the TA register is printed on the recording paper. Next, the process moves to step _S8 , where the taxable amount data in the TA register is multiplied by the tax rate, that is, TA0.0t is executed to calculate the tax amount data, and the TX of CPU1 is
written to the register. Next, the process moves to step _S9 , and the tax amount data in the TX register is stored in memory 5.
TX is accumulated in the storage area _MTX . Next, the process moves to step _S10 , where the tax amount data in the TX register is added to the Z register.
Addition is performed. Next, the process moves to step _S11 , and the tax amount data in the TX register is printed in the print buffer.
It is transferred to PR and printed on the recording paper. Next, the process moves to step _S12 , where it is determined whether the content of the flag area F of the CPU 1 is "0" or "1", and if it is "0", the process moves to step _S13 . In executing step _S13 , the flag area F
``1'' is written in ``1'', and then the process moves to step _S14 , where each data stored in the tax memory T2 is read out, and then the process moves to step _S2 .

In step _S12 , "1" is set in the flag area F.
If it is stored, the process moves to step _S15 .
In executing step _S15 , "0" is written in the flag area F. Next, the process moves to step _S16 , where Z accumulation is performed in which the cash sales total data stored in the Z register is accumulated in the storage area _MZ of the memory 5. Next, the process moves to step _S17 , where the total cash sales data in the Z register is printed on the recording paper. Next, the process moves to step _S18 , where the contents of the Z register are cleared. Next, the process moves to step _S19 , where the person in charge of key operation and the receipt issue number are printed on the recording paper. Next, proceed to step _S20 ,
The date and time are printed on the recording paper.

When the cash/deposit key is operated, steps S ₁ to S ₃ and S ₅ to _{S 12} are sequentially executed.
By operating the taxation key T/S ₁ on the recording paper, "TA1 13.00" indicating the entered taxable amount is printed, and further "TX1 1.30" indicating the tax amount is printed. Continue steps S ₁₃ , S ₁₄ , S ₂ , S ₄
~ _S12 are executed sequentially, and as a result, "TA2 7.83" indicating the taxable amount input by operating the taxation key T/S ₂ is printed on the recording paper, and further,
The tax amount "TX2 1.17" will be printed. after that,
As a result of sequentially executing steps _S15 to _S20 , the cash sales total data "CASH 23.30", the name of the person in charge, the receipt issue number, the date, and the time are printed in sequence on the recording paper.

Figure 6 shows "TA1" to "CASH" printed on the recording paper according to the combination in which AOT code or VAT code is set as identification codes TI1 and TI2 set in tax memories T1 and T2.
In this case, AOT,
It is assumed that each tax rate of VAT is the same as in the above case, and that the same input operations as in FIG. 3 have been performed.

The formula for calculating the tax amount is:
Although two types of cases, AOT and VAT, have been described, the present invention is not limited to this, and can be carried out in exactly the same way when calculating the tax amount using other arithmetic expressions.

[Effects of the Invention] According to the present invention, it is only necessary to set the tax rate for the first taxation key and the second taxation key, and the effort required for setting can be extremely reduced.

Even if products whose tax amounts are calculated using different calculation formulas coexist in the same department, registration can be easily performed.

It has the following effects.
