[0001]

BACKGROUND OF THE INVENTION The present invention relates to an electronic register (EC
R), a POS system, a sales data processing device used in a data terminal, and the like, and more specifically, to a sales data processing device that calculates a tax amount of a product.

[0002]

2. Description of the Related Art Electronic registers (hereinafter referred to as ECR),
Alternatively, the POS terminal device accumulates (registers) sales data.
Then, the sales data is output, and the registered sales amount, the number of sales, and the like are inspected and settled.
It is a terminal device that is installed in sales areas such as supermarkets and convenience stores, and immediately collects data used for product management, customer management, sales management, and the like.

In the conventional ECR, when calculating the tax of a product, the total amount of each product is set as a taxable amount, a tax rate is calculated for the total amount, and the tax table is based on the total amount. I am doing calculations.

[0004]

However, in the tax calculation method in such a conventional ECR,
For one product, one kind of tax is multiplied and calculated,
It was possible to calculate by multiplying multiple types of taxes, but calculate by multiplying a portion of the price of a certain product by, for example, the tax of "A" and multiplying the remaining portion by the tax of "B". It was not designed to divide one product amount and calculate the divided amount with different taxes, so such divided amounts should be multiplied with different taxes. When it is necessary to calculate, there is a problem that the conventional ECR cannot handle it.

An object of the present invention is to make ECR compatible with a special tax calculation method.

Next, the operation of this embodiment will be described.

The tax calculation processing program executed by the CPU 13 shown in FIG. 2 will be described with reference to the flowchart shown in FIG.

First, when product data is registered by an operator's key operation on the input unit 11 (step S
1) Referring to the PLU file stored in the PLU memory 14h in the RAM 14, it is determined whether the status "T1" or "T2" corresponding to the registered product is set (step S2). If the status is not set, the process proceeds to the sales registration determination process in step S4, and if the status is set, the registration amount is stored in the NEW ST memory 14a that stores the new taxable subtotal total amount (( Step S3).

Next, it is judged whether or not the sales are registered (step S4). If the sales are not registered, the procedure returns to step S1. (25%) ”and“ T
2 (75%) "to divide the registration amount and store the divided registration amount in the TAST1 and TAST2 memories 14b and 14c (step S5).
Based on the divided registration amounts stored in the ST2 memories 14b and 14c, the tax amounts are calculated at different tax rates corresponding to the divided registration amounts (step S6), the normal closing process is performed, and this process is terminated ( Step S
7).

Below, an example of a specific calculation of the tax amount based on the above tax calculation processing will be shown.

For example, a product of PLU No: 0001,
When purchasing a unit price: 1,000 yen, the data stored in the RAM 14 is NEW ST memory: 1,000 TAST1: 250 TAST2: 750, and the tax rate for TAST1 is 3% and the tax rate for TAST2 is 5%. Then, TAX1 = 250 × 1.03 = ¥ 257.5 TAX2 = 750 × 1.05 = ¥ 787.5, and the tax amount is calculated for the divided road amount.

Therefore, the ECR 10 can cope with the tax system even when different product tax rates are imposed on a single product price.

In the above embodiment, the NEW ST memory 14 that stores the new taxable subtotal total amount in the RAM 14 is used.
Since "a" is provided and the divided registration amount is calculated immediately before the sales registration, the divided registration amount is calculated and stored in the TAST1 and TAST2 memories 14b and 14c for each product registration. Can be made smaller.
