Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention sells products such as an electronic cash register and a POS (point of sale information management) system in which a controller centrally manages a plurality of registers as terminals. The present invention relates to a data processing device, and more particularly, to an improvement of a product sales data processing device capable of registering taxable products of external tax or internal tax and non-taxable products.

[Prior Art] An electronic cash register used in a country or region in which a customer who purchases a product pays the excise tax levied on the product directly at a store etc. The one disclosed in Sho 53-43454 is known. This publication discloses a total memory for storing the total amount of sales for one customer in the internal storage unit, a taxable memory for storing the taxable amount of the total amount of money, and a tax-free memory for storing the tax-free amount. In addition to the provision, the tax type of the department to be taxed or the tax-exempt department is preset for all departments in the department memory for totaling the sales of each product by department. Then, when the product is registered, it is determined whether the department to which the product belongs is tax-free or tax-exempt,
In the taxable department, the sales amount is added to the total memory and the taxable memory, and in the tax-free department, it is added to the total memory and the tax-free memory. Therefore, the tax amount is calculated by multiplying the contents of the taxation memory by a preset tax rate.

[Problems to be Solved by the Invention] However, in the above-mentioned publication, it is necessary to preset the tax types of taxable departments or tax-exempt departments for all departments. Moreover, all products belonging to the same department have the same tax type, so even if the products should be classified in the same department, if the tax types are different, they must be classified in different departments. For this reason, the number of department codes for classifying products increases depending on the store, and it is necessary to spend a great deal of time and effort to set the tax type.

Therefore, the present invention is intended to provide a product sales data processing device capable of easily performing tax type setting work even when there are many types of products.

[Means for Solving the Problem] The first invention of the present application is to store at least tax types corresponding to a common tax type memory that stores common tax types for all products and a classification code that classifies all products. A taxonomy file is provided for each taxonomy area of this taxonomy file, and at least tax types other than the tax types stored in the common taxon memory are set for each taxon area of this taxonomy file. When the sales item is registered by the means and the product registration means, when the tax type is set in the tax type area of the classification file corresponding to the classification code to which the sales item belongs, the sales item is registered according to the tax type. The product sales data processing device is provided with a product registration control unit that performs registration processing and, when not set, registers the sold product according to the tax type in the common tax type memory.

The second invention of the present application is, in addition to the files for each classification,
A product-specific file that stores the classification code to which the product belongs corresponding to the product code set for each product and at least a tax type area for storing the tax type is provided. A tax type setting means for selectively setting at least a tax type other than the tax types stored in the common tax type memory, and when the sale item is registered by the item registration means, it corresponds to the item code of the sale item. The first judging means for judging whether or not the tax kind is set in the tax kind area of the file for each product, and when the judging means judges that the tax kind has been set, the sales product is registered according to the tax kind. When the first product registration control means for processing and the first judging means judge that there is no tax type setting, the tax type is set in the tax type area of the classification file corresponding to the classification code to which the sale product belongs. The second judging means for judging whether or not there is a tax type setting, and when this judging means judges that the tax type is set, the sale product is registered according to the tax type, and when it is judged that the tax type is not set, the common tax type is set. It is a product sales data processing device provided with a second product registration control means for registering the sales product according to the tax type of the memory.

[Operation] In the product sales data processing device according to the first aspect of the present invention, when a sales product is registered by the product registration means, it is first determined whether or not a tax type is set in the tax type area of the classification code to which the sales product belongs. To be judged. Then, if it is set, the sales product is registered according to the tax type.
On the other hand, if it is not set, the product is sold and registered according to the tax type in the common tax type memory. Therefore, it is not necessary to set the tax types for all the classification codes, and it is sufficient to set the tax types that correspond only to the classification codes designated for the tax types other than the tax types stored in the common tax type memory.

Further, in the case of the product sales data processing device of the second invention, when the sales product is registered by the product registration means, it is first determined whether or not the tax type is set in the tax type area of the product code of the sales product. It Then, if it is set, the sales product is registered according to the tax type. On the other hand, if not set, it is determined whether or not the tax type is set in the tax type area of the classification code to which the product belongs. Then, if it is set, the sales product is registered according to the tax type. On the other hand, if it is not set, the product is sold and registered according to the tax type in the common tax type memory. Therefore, for a product of a tax type different from the tax type of the classification code to which it belongs, the corresponding tax type may be set in the tax type area corresponding to the product code.

If the tax type data [2] is set in the common tax type memory RA4, the tax registration flag F2 is set to "10", and the sales amount of the above-mentioned sale item is set in the second total taxable amount memory RA3 ( Add the registration amount). Common tax type memory
If the tax type data [3] is set in RA4, the tax registration flag F2 is set to "00". (Second product registration control means) After that, the sales amount (registered amount) of the above-mentioned sold product is added to the total amount memory RA1 and the PLU-specific file RA13 is added.
Add the above sales amount, sales points, etc. to the corresponding PLU sales memory. Further, the sales amount, the number of sales, and the like are added to the sales memory of the sales section to which the sales product belongs in the file RA12 by section. Further, the department code to which the sale product belongs and the sales amount are displayed on the display units 3 and 6, and the printer is driven to print out on a receipt or the like, and the registration flag F1
Is set to "1" and the key processing is terminated.

In FIG. 5, if the input key signal in the “registration” mode is the deposit / cash total key 10, the deposit / account of FIG.
Proceed to the current total key registration process. Here, the registration flag F1
Is confirmed to be "1", the taxable amount in the first total taxable amount memory RA2 is multiplied by the tax rate set in the first tax rate memory RA5 to calculate the tax amount P1. Next, it is determined whether the tax type corresponding to the first taxation key 14 is an external tax or an internal tax, and if it is an external tax, the tax amount P1 is added to the total amount memory PA1. This addition process is not performed for in-house tax. Next, the taxable amount in the second total taxable amount memory RA3 is multiplied by the tax rate set in the second taxable rate memory RA6 to calculate the tax amount P2. Next, it is determined whether the tax type corresponding to the second taxation key 15 is an external tax or an internal tax, and if it is an external tax, the tax amount P2 is added to the total amount memory PA1. This addition process is not performed for in-house tax.

After that, the total amounts of the total memories RA1 to RA3 and the calculated tax amounts P1 and P2 are accumulated in the corresponding area of the transaction-specific memory RA14. Further, the total amount, deposit amount, change amount, etc. are displayed and printed, the drawer 5 is opened, and the receipt issuance port 4 issues a receipt. After that, the total memories RA1 to RA3 are cleared and the registration flag F1 is set to "0".
Then, the key processing is finished.

In the present embodiment having such a configuration, first, the common tax type memory RA4 is set with a tax type common to all products. That is, after the "setting" mode is selected by the control key 17, the main code "11" is first entered by the numeric key 7 and the multiplication key 12 is then entered. Next, tax type data “1”
After inputting any one of "3" with the numeric keypad 7, input the deposit / cash total key 10. By doing so, the common tax type memory RA4 is set to a tax type common to all products.

Next, in each department that classifies all products, if the tax type of each product belonging to that department is different from the tax type in the common tax type memory RA4, in the tax type area A1 of that department in the file RA12 for each department Set different tax types. That is, in the "setting" mode, the main code "12" is first entered with the numeric keypad 7, and then the multiplication key 12 is entered. Next, one of the different tax type data is entered with the entry key 7, and then the subtotal key 9 is entered. After that, the department key of each department for which the tax type data is designated is sequentially input. By doing so, a tax type different from the common tax type is selectively set in the tax type area A1 corresponding to the department code of each department key 8 that has been key-inputted.

Next, for a product for which another tax type is designated in the same department, a different tax type is set in the tax type area A2 of the corresponding product in the PLU-specific file RA13. That is, in the state where the main code “12” is set in the “setting” mode, the tax type data is entered with the entry key 7 and then the subtotal key 9 is operated. After that, the PLU code of the corresponding product for which the tax type data is specified is sequentially input with the numerical key 7 and the PLU key 11. This will ensure that each PLU keyed in is
A tax type different from the tax type of the department to which the corresponding product belongs is selectively set in the tax type area A2 corresponding to the code.

In this way, when the setting process of the necessary data is completed, the product registration work becomes possible. Then, when the "Register" mode is selected by the control key 17 and the department code of the sale item is input by the department key 8 without operating the tax type selection keys 14-16, first, the department file RA12 is input. The tax type area A1 corresponding to the department code is searched.
Here, data "1" to "3" in the tax area A1
If is set, the registration process according to the tax type is executed. That is, if the data is "1", it is a taxable product of the tax type corresponding to the first taxation key 14. Therefore, the sales amount of the sale product is in the first taxable total amount memory RA2, the total amount memory RA1 and the divisional file RA12. Addition processing is performed on each sales memory of the department. If the data is “2”, it is a taxable product of the tax type corresponding to the second taxation key 15. Therefore, the sales amount of the sale product is the second taxable amount total memory RA3, the total amount memory RA1 and the department in the file RA12 for each department. It is added to each sales memory. If the data is “3”, it is a tax exempt product, so the total sales amount of the sales product is the memory RA1 and the department file RA1.
Addition processing is performed on each of the section 2 sales memories.

On the other hand, if tax type data “0” is set in the tax type area A1 corresponding to the input department code of the department file RA12, similar registration processing is performed according to the tax type in the common tax type memory RA4. .

In addition, PL of the product sold without operating the tax type selection keys 14-16
When the U code is entered using the numeric keypad 7 and the PLU key 11, the tax area A2 corresponding to the input PLU code in the PLU-specific file RA13 is searched first. Here, the tax area A2
If the data “1” to “3” is set in, the registration process according to the tax type is executed. On the other hand, if the tax type data “0” is set in the tax type area A2, the tax type area A1 of the department to which the registered merchandise belongs is searched next. Then, when the data "1" to "3" is set in the tax type area A1, the registration process according to the tax type is executed. On the other hand, if the data "0" is set also in the tax type area A1, the registration processing is performed according to the tax type in the common tax type memory RA4.

When the registration of all the products purchased by one customer is completed, the deposit / cash total key 10 is entered. Then, the tax amount P1 is calculated at the tax rate in the first tax rate memory RA5 with respect to the taxable amount accumulated in the first total taxable amount memory RA2. Similarly, the tax amount P2 is calculated at the tax rate in the second tax rate memory RA6 for the taxable amount accumulated in the second total taxable amount memory RA3. Then, the tax amount of the external tax is added to the total amount in the total amount memory RA1 to calculate the total amount including the tax, and the total ends.

As described above, according to this embodiment, it is only necessary to set the tax type common to all products in advance and set the tax type in the tax type area applicable only to exceptional departments or products. Alternatively, it is not necessary to set the tax type for each product, which greatly simplifies the tax type setting work. Further, even products with different tax types can be classified as the same department, so that there are less restrictions on product classification, and highly practical data management can be realized.

In the above embodiment, the department code is shown as the product classification code, but the product code is not limited to this, and can be applied to classification such as class and group. It goes without saying that the present invention is also applicable to a product sales data processing device which does not have a classification-specific file but has only a product-specific file and performs product registration by inputting a product code such as PLU or EAN. Furthermore, it is needless to say that the present invention can be applied to a POS system in which a plurality of electronic cash registers are centrally managed by a controller.
