JP2866387B2 - Calculation method of per capita account in register - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an arithmetic processing method by a POS or other accounting processor (hereinafter referred to as a register), and particularly to a per capita account.

[Conventional technology]

Conventionally, in pubs and pubs, customers have often been requested to present an even discounted account amount at the register after the total is completed. Since the register does not have such a function of making an account, the accountant has separately calculated the demand of the customer using a calculator or the like.

[Problems to be solved by the invention]

The per capita account is calculated manually, irrespective of the register, so that it takes a long time for the accounting process, and it is easy for the customer to feel uneasy. Further, if the number is divided arithmetically by the number of customers, it may be less than one yen unit, and the customer and the accounting clerk must consider how to handle the fraction, which is complicated.

An object of the present invention is to provide an arithmetic processing method capable of performing fraction processing efficiently and not so unequally in view of the above circumstances.

[Means for solving the problem]

According to the present invention, as a calculation processing method in which the total purchase price and the number of customers from a large number of customers are recorded as accounting data in a register and the purchase price is displayed as a per capita account, a Select and enter a flag indicating a predetermined unit amount (flag amount) required for fraction processing,
b.The purchase price is rounded up according to the input flag according to the input flag.c.After the fractional purchase price is divided by the number of customers, the value obtained by rounding down the fractional value with the flag price from the divided value is used as the reference price. D. Subtract the amount obtained by multiplying the base amount by the number of customers from the rounded purchase amount, and e. Add the flag amount to the base amount by dividing the subtracted amount by the flag amount, and add a positive account amount After the process of determining the number of persons, the reference amount and the plus account amount are allocated, the number of persons is divided, and the fractional amount obtained when the purchase amount is rounded is displayed as change.

[Action]

The principle of the method of the present invention will be described. In the following, (a) to (e) are entered in each case relating to the items a to e described in [Means for Solving the Problems].

Assuming that the flag amount is Z, the purchased amount is first rounded up. (B) Fraction processing purchase amount = mZ is a multiple of Z. The number of customers is n, and the above mZ is n
(C) mZ / n = lZ + p (p <Z) lZ is a reference amount, and to show it, if the expression is modified as [lZ], (d) mZ− [lZ] · n = np Since the right side of the equation is a multiple of Z, (e) np = n'Z. Here, it is clear that n '<n, and the distribution of mZ is given by mZ = [lZ] n + np = [lZ] (nn-) + [lZ] n' + n'Z = [lZ] (n-n ' ) + {[Lz] + Z｝ n 'That is, it can be seen that the customer of n-n' should have the reference amount and the customer of n 'should have the plus account amount. Note that np = n'Z
Is performed on the premise that n 'customers are given a plus of only Z per person, in order to minimize the inequality in the allocation.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 shows the configuration of a normal POS register. The CPU 1 controls the keyboard 2, the display 3, and the printer 4. RAM5 stores temporary data during operation, and ROM6 stores programs. The floppy disk 7 is an external memory.

In the present invention, it is assumed that data necessary for all accounting processing is input from the keyboard 2, a temporary accounting processing is performed, and the data is stored in the RAM 5. In this case, the number of customers and the total purchase price are entered, and a per capita account is started at the request of the customer. First, as fraction processing,
For example, consider three types: 1 yen, 10 yen, and 100 yen. In the case of 10 yen, the amount less than 10 yen is rounded up or down. The amount is coded as flags "0", "1", and "2", and is input from the keyboard 2 according to a customer's instruction.

Next, arithmetic processing is performed by the arithmetic steps (1) to (6) shown in FIG. When the display calculation is completed, the data is displayed on the display 3, and after the payment, the data is printed out by the printer 4 together with other data.

 Hereinafter, calculation examples 1 and 2 will be described.

EX1. Purchase price 10217 yen Number of customers 3 people Flag “1” (10 yen) (1) 10220 (2) 10220/3 = 3406.6 (3) 3400 (4) 10220-3400 × 3 = 20 (5) 20/10 = 2 (6) 1 person 3400 yen 2 people 3410 yen Change 3 yen EX2. Purchase price 6380 yen Number of customers 3 Flag “2” (100 yen) (1) 6400 (2) 6400 ÷ 3 = 2133.3 (3) 2100 (4) 6400-2100 x 3 = 100 (5) 100/100 = 1 (6) 2 people 2100 yen 1 person 2200 yen Change 20 yen [Effect of the invention] As described above, fractional processing is performed in the per capita account. The unit price can be set in several types, and the purchase price is first rounded up with this amount (flag amount) to obtain a fractional numerical value. Since this number is an integral multiple of the flag amount, a specific number of customers can be set as a plus account amount that is extra paid by the flag amount with respect to the reference amount, and the others can be set as the reference amount. . Both amounts are multiples of the unit price and are not fractional. However, the fraction at the time of the first purchase price increase is returned to the customer as change.

As described above, in the accounting business, calculation using a special calculator or the like is not necessary as in the related art, and the equal-cost account can be quickly displayed by simply designating a flag using data already in the register. Therefore, there is an excellent effect of improving the service at the store.

Claims (1)

(57) [Claims] In a register, a total amount of purchases from a large number of customers and the number of customers are recorded as accounting data, and a calculation processing method for displaying the purchase amount as a per capita account, comprising: a. Select and enter a flag indicating a predetermined unit amount (flag amount) required for processing, b. Round up the purchase amount according to the input flag, c. After dividing by the number of customers, the value obtained by rounding down the divided value with the flag amount from the divided value is used as the reference amount, d. Subtracting the amount obtained by multiplying the reference amount by the number of customers from the rounded purchase price, e. By dividing the amount by the flag amount, the flag amount is added to the base amount to determine the number of people who will be the positive account amount. After the process, the base amount and the positive account amount are assigned.
An arithmetic processing method characterized in that the number of persons is divided and a fractional amount obtained when the purchase amount is rounded is displayed as change.
