Abstract

PURPOSE:To easily execute desired fraction processing by calculating the fraction processing, which is determined in advance, to each amount of transaction and executing addition or calculating the fraction processing, which is determined in advance, to the amount adding the transaction amount and displaying the calculated amount while responding to the output of an input means. CONSTITUTION:For the transaction amount inputted by the input means 4, the fraction processing determined in advance is calculated to each transaction amount in a fraction calculating means 1, namely, fraction processing calculation is executed to the respective sales prices of the respective commodities and fraction processing calculated results are added. Then, the amount to be paid is calculated. Otherwise, the fraction processing calculation is executed to the amount adding the transaction amounts, for example, to the amount adding the respective prices of the respective commodities. Further, the fraction processing calculation is executed to a result adding an external tax amount to the prices of the respective commodities or to a total amount for the sales prices of the respective commodities. Then, a calculated result is displayed in a display means 2. Thus, since the fraction processing calculation can be executed for the desired unit, operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a new electronic cash register capable of so-called rounding.

Due to the implementation of the conventional technical consumption tax, it has become necessary to handle fractional amounts in units of 1 yen or 10 yen. Particularly in stores that handle high-value items, handling small amounts of 1 yen or 10 yen is unnecessarily time-consuming. Therefore, there is an increasing desire to round off such small amounts, for example by discounting them.

In conventional electronic cash registers, in order to perform such rounding of small amounts, a subtotal discount registration operation is performed for each transaction, thereby discounting the small amount.

In such prior art, a subtotal discount registration operation must be performed for each transaction, and since such discount registration is not automatically performed, there is a problem in that it is time-consuming.

In addition, when rounding small amounts using a conventional electronic cash register, electronic cash registers that have an automatic discount function will add 1 yen to the total amount at the time of closing registration. It is configured to automatically discount only those items.

Problems to be solved by the invention In such prior art, only the 1 yen digit is treated,
Moreover, it is inconvenient that only discounts can be made and it is not possible to round up or round off.

It is an object of the present invention to provide a novel electronic cash register that allows the small portion of a transaction amount to be rounded down, rounded up, or rounded down as desired.

Means for Solving the Problems The present invention provides a means for inputting a transaction amount and, in response to the output of the input means, calculating and adding a predetermined rounding amount for each transaction amount, or This is an electronic cash register characterized by including a fraction calculation means for calculating a predetermined fraction processing for the sum of sums, etc., and means for displaying the output from the fraction calculation means.

According to the present invention, the transaction amount inputted by the input means is calculated in the fraction calculation means by a predetermined rounding process for each transaction amount, that is, for the individual sales amount of each product. Perform a rounding operation and add the results of the rounding operation to determine the amount due, or alternatively, the transaction amount plus the individual amounts for each item, for example. The calculation result of such a rounding calculation means that performs a rounding calculation and further performs a rounding calculation on the result of adding the tax excluding tax to the amount of each product or the total sales amount of each product. can be displayed by means of display means, such as printed display on recording paper such as a receipt, visual display using a cathode ray tube or liquid crystal display element, or acoustic display using voice synthesis or the like. In this way, it becomes possible to perform a desired rounding calculation in a desired unit such as 1 yen, 10 yen, or 100 yen, thereby improving operability.

Embodiment FIG. 1 is a block diagram of an embodiment of the present invention. This electronic money registration machine can be used, for example, in a store, and can perform various desired rounding operations. This electronic cash register includes a processing circuit 1 realized by a microcomputer or the like, and a visual display means 2 realized by a cathode ray tube or a liquid crystal display element for visually displaying transaction amounts and other amounts. , a printer 3 for printing and displaying the transaction amount on record paper such as a receipt, and an input means 4 for inputting the transaction amount and other information, which includes numeric keys and mode keys for controlling operations. , a drawer 5 which is a drawer for storing money such as coins and banknotes, a read-only memory 6 in which a program for controlling calculation operations on a processing date 281 is stored, and a random access memory used for transaction calculations. It has a memory 7. This random access memory 7 includes a memory M1 that stores the subtotal of sales for each transaction, a memory M2 that stores the sum of the taxable amount for each transaction, and a memory M2 that stores the subtotal of the taxable amount for each transaction. It has a difference summator M3 which is a memory for calculating and storing the sum of positive or negative amounts with the amount after performing the rounding calculation, and a memory M4 for setting the rounding mode. In the memory M2 described above, a subtotal of the taxable amount of -transactions is stored, and this value represents the sales of taxable products.

The second [21] is a flowchart for explaining the operation of setting the mode of the rounding calculation. Moving from step a1 to step a2, a rounding calculation mode is set by operating the input means 4, and the rounding calculation mode is stored in the memory M4, which is a part of the random access memory 7. This set rounding calculation mode is
On recording paper 8 such as a receipt shown in FIG. 3,
It can be displayed and confirmed as shown by reference numeral 9.

In the example shown in FIG. 3, it represents 49 50 people, in other words, if the transaction amount is 49 yen or less, it is treated as zero yen, and 50
0 yen to 99 yen represents a rounding calculation mode in which the value is 100 yen.

The specific operating procedure in the input means 4 for setting the rounding calculation mode shown in step a2 of FIG. 2 described above is shown in FIG. In order to set such a rounding calculation mode, r274J is input in the input means 4.
First, enter , then enter the decimal point, and then operate the multiplication key that is operated to perform the multiplication operation. Then, input a total of 6 digits as shown in A-F of Table 1.

Table 1 Each mode of the rounding operation stored in memory property 4 in FIG. 2 is illustrated as 1 to 12 in Table 2.

(Left below) Here, tax included means 3% of the sales amount of the product, where A is the transaction amount of the product, that is, the payment amount.
% consumption tax is added, it is 3A/103, and the taxable amount is 100A/103. In addition, the tax-excluded tax is 0.03·B, where B is the transaction amount of the product, that is, the payment amount, and the taxable amount is B.

After inputting the six-digit numbers A to F, the user operates the cash closing key, which is displayed as "Current/Deposit", in order to complete the setting of the fraction processing calculation mode.

The processing circuit 1 performs calculation operations according to modes 1 to 12 of fraction processing calculations stored in the memory M4.

The registration mode will be explained with reference to FIG. 5(1). Moving from step b1 to step b2, by operating the input means 4, the department to which the product belongs is determined as P L U (pr
ice 1look up) code and JAN (jou
r++al) Enter the code etc. to register the product.
As a result, the unit price and category of the product being traded, and whether the product is a taxable product under the tax-inclusive or tax-exclusive system are determined based on the contents stored in the random access memory 7.

In step b3, the registered amount, which is the product of the input product unit price and number of products, is added and stored in the memory M1 to obtain a sales subtotal. Also, if the product is a taxable product,
In step b2, the subtotal of the taxable amount of the taxable products is added and calculated.

When it is determined in step b4 that the registration has been completed, cash is deposited from the customer in step b5, and a closing registration is performed using the input means 4.

In step b6, the consumption tax is calculated by multiplying the consumption tax rate stored in the memory 7 in advance by the taxable amount in the tax-inclusive method and the tax-exclusive method stored in the memory M2. The amount to be paid by the customer is determined by calculating the sum of the sales subtotal for one transaction stored in the memory M1 and the tax-exclusive amount of the product under the tax-exclusive method.

In step b7, a rounding operation is performed on this total amount according to the mode of rounding operation stored in the memory M4 to determine the final sum actually to be paid by the customer. At the same time, the difference between the total and the final total is calculated in the memory M3 and added to the value in the memory M3.

In step b8, the final total after the rounding calculation is processed for final registration, and is printed and displayed on the recording paper 10, which is the receipt shown in FIG. 6. Then, the registered sales subtotal is 2,3
50 yen, and the tax-excluded amount is 2.350 yen, which is 3%.
If the consumption tax is calculated as the tax-exclusive amount, it will be 70 yen, so the total of the sales subtotal and the tax-exclusive amount will be 2,420 yen. For example, if the rounding calculation mode 9 in Table 2 is stored in the memory M4 and there are 80 people to the nearest 20, in this example, 20 yen is rounded down and the final total is 2.
, it will be 400 yen. Therefore, the cash display is 2,400
Print as a circle.

In this way, the customer pays 2,400 yen, and the above-mentioned 20 yen rounding calculation has been performed, thereby eliminating the hassle of handling such small 20 yen coins.

As shown in Figure 5 (2), in the inspection/Mg mode of the electronic cash register machine, the process moves from step c1 to step c2, and all items, that is, all products are inspected/
The fW calculation is performed, and the total difference in the memory M3 is displayed, and the included tax amount and exclusive tax amount are determined.

In the above-described embodiment, the rounding process is calculated by adding the tax-excluded amount to the sum of the transaction amount. However, as another embodiment of the present invention, as shown in FIG. , the total may be calculated by performing rounding calculations for each transaction amount, that is, for each unit price of one product. In other words, the process moves from step d1 to step d2, and registration for each product is performed using the input means 4, and then In step d3, a calculation is performed to round off the unit price. In step d4, the rounding calculation results are sequentially added for one transaction and totaled. This total value is printed and displayed by the printer 3 in step d5, and the series of transactions is completed in step d6.

The contents printed and displayed by the printer 3 and other contents can also be displayed by the visual display means 2.

Effects of the Invention As described above, according to the present invention, desired rounding can be easily performed, operability is improved, and rounding calculations can be performed without much effort. Furthermore, calculation errors can be prevented during rounding. Furthermore, it is possible to realize an electronic cash register which is convenient because it can automatically perform complicated rounding, and which can precisely meet the needs of various stores. Moreover, since such rounding can be performed in a desired manner, transactions can be carried out without actually handling hard or banknotes of small denominations, thereby eliminating inconvenience.
