Abstract

PURPOSE:To enable a tax-on-tax process by successively performing arithmetic wherein a 1st tax amount of money is found from an object amount of taxation and added to the object amount of taxation and a 2nd tax amount is found from a 2nd object amount of taxation. CONSTITUTION:When an article of, for example, PLU001 is registered, a 1st arithmetic means 1 totalize the proceeds of this article to find the object amount of taxation for state taxation and multiplies this object amount of taxation by a specific rate to find the 1st tax amount. A 2nd arithmetic means 2 adds the 1st tax amount to the object amount of taxation to find the 2nd object amount of taxation and multiplies this 2nd object amount of taxation by the specific rate to find the 2nd tax amount. A specifying means 3 specifies the successive arithmetic of the 1st arithmetic means 1 and 2nd arithmetic means. The tax-on-tax process, therefore, becomes possible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sales data processing device such as an electronic cash register, a POS terminal or the like, which is compatible with a tax-on-tax method for calculating a second tax based on a taxable amount including a first tax.

[0002]

2. Description of the Related Art Depending on the region, two types of tax, national tax (or state tax) and city tax, are levied on purchased products. That is, the state tax is levied on the product amount, the tax-included amount including the state tax becomes the taxable amount of the city tax, and the city tax is calculated. For example, if a product of 1000 yen is purchased, the state tax is first calculated at the state tax rate (for example, 10%), and the state tax amount of "100 yen" is calculated. Next, the tax-included amount "1100 yen", which is the state tax amount "100 yen" added to the product amount "1000 yen", becomes the taxable amount of the city tax, and this taxable amount is the city tax rate (20%). The calculated amount of "220 yen" is the amount of city tax. Therefore, the total tax is "320 yen".

[0003]

However, since the conventional sales data processing device separately calculates the state tax and the city tax for the product amount, the tax-on-tax method is adopted. There was a problem that it could not be used in the area. An object of the present invention is to enable tax-on-tax processing.

[0004]

The means of the present invention are as follows. The first calculation means 1 (see the functional block diagram of FIG. 1, the same applies hereinafter) is a registered product (for example, PLU001).
The taxable amount is obtained by accumulating the sales amount of the above, and the first taxable amount (for example, state tax) is obtained by multiplying the taxable amount by a predetermined rate. The second calculation means 2 adds the first tax amount and the taxable amount to obtain the second taxable amount, multiplies the second taxable amount by a predetermined rate, and then the second tax. Ask for the amount (eg city tax). Designating means 3
Specifies that the first computing means 1 and the second computing means 3 should be continuously operated.

[0005]

The operation of the means of the present invention is as follows. For example, when a product of PLU001 is registered, the first calculation means 1 accumulates the sales amount of this product to obtain a taxable amount for the state tax, and a predetermined rate (eg 10
%) To obtain the first tax amount (eg state tax). The second computing means 2 adds the first tax amount and the taxable amount to obtain the second taxable amount, and the second taxable amount is calculated.
The second tax amount (for example, city tax) is calculated by multiplying the taxable amount of No. 1 by a predetermined rate (for example, 20%). The designating means 3 designates that the computations of the first computing means 1 and the second computing means 3 are continuously performed. Therefore, tax-on-t
Can do ax processing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. FIG. 2 is a block diagram showing the circuit configuration of the sales data processing device. The key input unit 11 includes a numeric keypad 11a for inputting numerical data, a mode switch 11b for designating various modes, and various other keys necessary for registration. When a key is operated on the key input unit 11, a key input signal corresponding to the key operation is input to the CPU 12.

The CPU 12 includes a calculation unit 12a and a control unit 1.
2b is built in and controls each part based on the control program stored in advance in the ROM 13 and executes various processes. In addition to the ROM 13, the CPU 12 has a RAM
14, the display unit 15, the printing unit 16, and the drawer 17 are connected.

The RAM 14 is a memory for storing various data. The RAM 14 has a work area as shown in FIG. The work area includes an internal totalizer ST that stores a subtotal amount, an internal totalizer TA1 that stores a taxable amount to which the first tax (state tax) is charged, a second tax (city) that does not include the first tax. Internal totalizer TA2 that stores the taxable amount to which tax is applied, and an internal adder T that stores the taxable amount to which the second tax (city tax) is included, including the first tax
It is composed of A1 + 2. In addition, the RAM 14 corresponds to the PLU numbers of PLU001 to PLU999 and the taxabl
It has a PLU memory in which e status and the like are set and stored.

Next, the operation of the above embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing the operation. In this case, it is assumed that "1000 yen" is purchased for the PLU001 product. The operator operates the key input unit 11 to “1000”
Enter "PLU001". When the key is entered, the processing of FIG. 3 is started.

First, in step S1, the item registration process is executed, and the sales amount "1000 yen" of the product is RA.
It is stored in M14. That is, the sales amount of PLU001 is "100.
“0 yen” is stored in the internal totalizer ST of the RAM 14.

Next, in step S2, it is judged whether or not a taxable status is set in the PLU memory corresponding to the input product classification (PLU001 in this case). In step S2, there is taxable status YES
If it is determined to be NO, the process proceeds to step S3, and if NO, the process proceeds to step S6. If the PLU001 has the taxable status, the process proceeds to step S3.

In step S3, it is determined whether or not the sales data processing device is set in the tax-on-tax system. In this case, for example, a tax-on-tax system is set by a DIP switch or the like. Step S
If YES is determined in step 3, the process proceeds to step S4, N
In the case of O, the process proceeds to step S5. In this case, tax-on-tax
It is assumed that the system of the method is set.

In step S4, the internal totalizers TA1, T
The sales amount "1000 yen" is added to each of A2 and TA1 + 2. After execution of step S4, the process proceeds to step S6.

If it is determined in step S3 that the system is not the tax-on-tax system and is NO, step S5.
And proceed to the internal totalizer TA1 according to the taxable status above.
Or, the sales amount "1" is added to either the internal totalizer TA2.
000 yen "is added. After execution of step S5, the process proceeds to step S6.

In step S6, whether finalize or not,
That is, it is determined whether or not the closing process is designated. If YES is determined in step S6, the process proceeds to step S7, and if NO is determined, the process returns to step S1. When the operator operates the key input unit 11 to input a closing key such as a "cash / deposit" key, the process proceeds to step S7.

In step S7, the internal totalizer TA1 + 2
It is determined whether or not the data is stored in. If YES in step S7, the process proceeds to step S8, and if NO, the process proceeds to step S9. Since the sales amount "1000 yen" is stored in the internal totalizer TA1 + 2, the determination result is YES and the process proceeds to step S8.

In step S8, the internal totalizer TA
From the sales amount "1000 yen" stored in 1 + 2, the tax amount of the state tax is calculated and added to the internal totalizer TA2. That is, since the tax rate of the state tax is 10%, “1000 × 0.
By calculating "1", the tax amount of the state tax becomes "100 yen", which is stored in the internal totalizer TA2 "1000 yen".
Therefore, the internal totalizer TA2 is "1100 yen". The process proceeds from step S8 to step S9.

In step S9, the internal totalizers TA1, T
The tax amount of state tax (TX1) and the tax amount of city tax (TX2) are calculated from the stored contents of A2, "1000 yen" and "1100 yen", respectively. That is, since the tax rate of the state tax is 10%, the tax amount of the state tax (T
X1) is “100 yen”, and the tax rate of the city tax is 20%. Therefore, the tax amount (TX2) of the city tax is “220 yen” by the calculation of “1100 × 0.2”. Then, the sales amount "1000 yen" stored in the internal totalizer ST is added to the state tax tax amount "100 yen" and the city tax tax amount "220 yen".
Is added, and the subtotal amount stored in the internal totalizer ST is “1320 yen”.

Therefore, the subtotal amount "1320 yen" stored in the internal totalizer ST is displayed on the display unit 15, and
As shown in FIG. 4, the sales amount of PLU001, the taxable amount of state tax (TA1), the taxable amount of state tax (TX1), the taxable amount of city tax (TA2), the taxable amount of city tax (TX2), The subtotal amount (ST) is printed on the receipt. Step S9
After execution of, the processing of FIG. 3 ends.
