DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a POS terminal will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a main configuration of a POS terminal. The CPU (Central Processing Unit) 10 is the PO
The main body of the control unit of the S terminal is configured, and each unit is controlled by a control program preset in a ROM (Read Only Memory) 11.

The ROM 11 and the RAM 12 are the POS
The main storage unit of the terminal is configured, and the ROM 11 is preset with fixed data such as the control program.
In M12, an area for setting variable data necessary for the data processing of the CPU 10 and an area for temporarily storing the data generated by the data processing of the CPU 10 are formed. The clock circuit 13 measures the current date and time, and the date and time data obtained from the clock circuit 13 is used for receipt printing and the like.

The CPU 10, the ROM 11 and the RAM 1
2 and the clock circuit 13 are connected by a bus line 14. Also, the bus line 14 has an I / O port 1
5, communication interface 16, keyboard controller 17, display controller 18, printer controller 1
9 and a scanner controller 20 and other input / output control units are connected.

The I / O port 15 inputs a signal from the mode switch 21 to notify the CPU 10. Further, in response to a command from the CPU 10, a drive signal is output to the drawer opening device 22 to open a drawer (not shown) for accommodating cash or the like.

The mode switch 21 is for selecting various work modes such as "registration", "inspection", "payment" and "setting". By the way, "registration" means that sales data of a product registered for sale by the product registration means is subjected to sales registration processing in the storage unit, and when the registration closing means closes the registration of one transaction, the sales registration processing of the product is performed. This is a business mode in which sales detail information and total sales information are printed on a receipt and issued. The "inspection" is a business mode in which the contents of the storage unit subjected to the sales registration processing by the "registration" are printed out on a recording paper and a sales totalization report is issued. "pay off"
Is a business mode in which the contents of the storage unit subjected to sales registration processing by “registration” are printed out on a recording sheet, a sales totalization report is issued, and then the storage unit is cleared. "Configuration"
Is a job for presetting data necessary for executing various job modes such as “registration”, “inspection”, “payment” in a storage unit.

The communication interface 16 is the PO
It controls transmission / reception of data performed via the communication line 24 with the file processor 23 which is a higher model of the S terminal. As shown in FIG. 2, the file processor 23 is provided with a single item file 29 in which a single item name, a link department, a unit price, and a tax classification code are preset for each individual item code of each item. Here, the tax classification code is a code for identifying the tax type of the corresponding product. In this embodiment, the tax classification code “1” is the product subject to the external tax, the tax classification code “2” is the product subject to the internal tax, and the tax classification is Code "3" is a tax exempt product.

The keyboard controller 17 includes a numeric keypad for inputting numerical data, a PLU key for indicating that the numerical data is a single item code, a registration closing key as registration closing means for instructing registration closing of one transaction, and the like. The keyboard 25 provided is controlled, the display controller 18 controls the display 26 for displaying the name and sale price of the registered product, the total price of one transaction, etc., and the printer controller 19 controls the printer for receipt printing. Then, the scanner controller 20 controls the barcode scanner 28 that optically reads the barcode attached to the product.

Here, a unique single-piece code is set for each product, and most products are attached or printed by converting the single-piece code into a bar code. And POS
The terminal reads the bar code of the product with the bar code scanner 28 and inputs it, or uses the numeric keypad of the keyboard 25 and the PLU.
The product is registered for sale by keying in the individual product code with the key. The bar code scanner 28 and the numerical keys and PLU key of the keyboard 25 constitute a product registration means.

The RAM 12 functions as a storage unit for performing sales registration processing of sales data of the products registered for sale by the product registration means. Further, in the RAM 12, as shown in FIG. 3, single item sales detailed information including a single item code, a single item name, a unit price, a sales point, a sales amount, etc. of a registered product, is a tax classification code indicating a tax type of the product. A work buffer 31 for storing and storing together with it, a counter area 32 for a registration number counter n, a read counter r, and a tax classification counter t, a flag area 33 for a registration flag F,
Various areas such as a print buffer 34, a transaction total area 35, an external tax target total area 36, an external tax area 37, and a total tax area 38 are formed.

Therefore, in the state where the "register" mode is selected by the mode switch 21 in the CPU 10,
It is programmed to perform the process shown in the flow chart of FIG.

That is, when the input of the single product code of the product for sale by the product registration means is detected in ST (step) 1, it is determined that the single product registration has been performed, and in ST2 the registration flag F in the flag area 33 is checked.

If the registering flag F is not set to "1", it means the first single item registration of one transaction.
In ST3, the registering flag F is set to "1". Further, in ST4, the transaction total area 35, the amount-of-tax-excluded total area 36, the external-tax area 37, the total-tax-included area 38
And the single work buffer 31 are cleared. Further, in ST5, the registered number counter n in the counter area 32
After being reset to "0", the process proceeds to ST6.

When the registration flag F is set to "1" in ST2, it means that the second and subsequent points of one transaction are registered, so that the processing proceeds to ST6 without performing the processing of ST3 to ST5.

In ST6, a single-item information inquiry message using the input single-item code as a search key is created and transmitted to the file processor 23 through the communication interface 16.
Upon receiving this inquiry message, the file processor 23 retrieves the single item file 29, and returns the single item information corresponding to the inquired single item code, the link department, the unit price, and the tax classification code. C received
The PU 10 acquires the product sales data by setting the sales amount data as the unit price in the single item information and the sales point data as “1”,
This product sales data is registered in the RAM 12 as sales by link department, for example. Further, in ST7, the sales amount data is added to the transaction totalizer area 35. Next, in ST8, the tax classification code in the single item information is checked to determine whether or not the sale item is a tax-exempt item. Then, if the tax classification code is "1", it is a product subject to tax exemption, and therefore, the sales amount data is added to the tax exempt amount summing device area 36 in ST9.
If the tax classification code is "2" or "3", the product is not subject to external tax, and therefore the process of ST9 is not performed.

Next, in ST10, the registration number counter n is incremented by "+1", and in ST11, single item sales detail information is created from the single item name data in the single item information and the sales amount data. The detailed information is stored in the n-th area of the single product work buffer 31 together with the tax classification code in the single product information (detail information storage means).

Thereafter, in ST12, it is judged whether or not the registration closing key is input. If there is no registration closing key input, ST1 is entered.
Return to and process the single item registration for the next sale item. That is, ST1, ST2, ST6, ST7, ST8, (ST
9), ST10 and ST11 are executed.

When the key input of the registration closing key is detected in ST12, in ST13, the total sales amount of the tax-exempted merchandise added in the tax-excluded amount sum total area 35 is set in advance. The external tax amount is calculated by multiplying the tax rate (for example, 3%), and this external tax amount is further calculated in the total transaction amount area 35.
The total amount of tax included is added to the total amount of sales of the sale item added in to calculate the total amount including tax, and the total amount including tax is displayed on the display unit 26.

Next, in ST14, the sales detailed information stored and stored in the single work buffer 31 is sorted by tax classification code and printed on the receipt by the printer 27 (tax type detailed information printing means).

Next, at ST15, the total transaction amount area 3
The contents of 5 are subtotals, and the amount of tax-exempt sum total area 3
The contents of 5 are set as the amount subject to external tax, and the printer 28 prints on the receipt together with the external tax amount and the total amount including tax calculated in ST13.

Next, in ST16, the receipt is issued, and an opening command is output to the drawer opening device 22 to open the drawer. Then, the registration flag F is registered.
Is reset to "0", and this processing ends.

FIG. 5 is a flowchart embodying the single item sales detail information printing process in ST14. That is, when this printing process is started, first, in ST21, the tax classification counter t in the counter area 32 is initialized to "1". Also, ST
At 22, the read counter r of the counter area 32 is also initialized to "1".

Next, in ST23, the single work buffer 31 is used.
The tax classification code is read from the area corresponding to the value of the read counter r (first area in this case). And ST2
At 4, it is determined whether the tax classification code matches the value of the tax classification counter t.

If they match, the product specification information is read from the area corresponding to the value of the read counter r of the single work buffer 31 in ST25, and if it is converted into receipt print data, it is set in the print buffer 34. After that, in ST26, the contents of the print buffer 34 are changed to the printer 2
Output to 7 and print data. If the tax classification code does not match the value of the tax classification counter t in ST24, ST2
5, the process of ST26 is not performed.

Next, when the read counter r is incremented by "+1" in ST27, the value of the read counter r is compared with the value of the registered number counter n in ST28. If the value of the read counter r is less than or equal to the value of the registered number counter n, there is data that has not been read in the single work buffer 31 while the tax classification counter r is at a predetermined value. Return, ST27
Repeat the above process. As a result, of the single-item sales detailed information accumulated and stored in the single-item work buffer 31, all the information whose tax classification code is equal to the value of the tax classification counter r are extracted and printed as a receipt.

Thus, when the value of the read counter r becomes larger than the value of the registered number counter n in ST28, S
Proceeding to T29, the tax classification counter t is incremented by "+1". Then, if it is confirmed in ST30 that the value of the tax classification counter t does not exceed "3",
Returning to ST22, the above-mentioned processing is repeatedly executed. If it is confirmed in ST30 that the value of the tax classification counter t exceeds "3", the sales item information accumulated and stored in the single product work buffer 31 is the tax-excluded product having the tax classification code "1", Since the tax-excluded product having the tax classification code “2” and the tax-exempt product having the tax classification code “3” are rearranged in order and the receipt is printed by the printer 27, the printing process is ended.

Next, the function and effect of this embodiment thus constructed will be described based on a concrete example.

Now, a customer selects "orange juice" and "ice cream" as tax-exempt products, "weekly magazine" and "beer" as tax-exclusive products, and "prepaid card" as tax-exempt products. Suppose you bought it. Then, the cashier operates the barcode scanner 28 or the keyboard 25 to select "weekly magazine", "orange juice", "beer", "prepaid card". It is assumed that the individual items are registered in the order of "ice cream".

Then, the single item work buffer 31 stores and stores the single item sales detail information and tax classification code of each of the above products in the order of registration.

Then, when the cashier operates the registration closing key to declare the end of registration of one transaction, first, the external tax amount is calculated from the total amount of the products subject to the external tax, and the total amount including tax is further calculated and displayed. As displayed on the container 26, the customer pays in proportion to the total amount including tax.

Further, a single item sales detail information printing process for each tax type is executed. That is, first, sales detail information of "orange juice" and "ice cream", which are tax-exempt products with tax classification code "1", is read from the single-item work buffer 31 and printed as a receipt. Next, the sales detail information of "weekly magazine" and "beer", which are tax-inclusive products with tax classification code "2", is read from the single-item work buffer 31 and a receipt is printed. Finally, the sales statement information of the "prepaid card", which is a tax-exempt product with the tax classification code "3", is read from the single-item work buffer 31 and printed as a receipt.

After that, the subtotal amount, the amount subject to external tax, the external tax amount,
The total amount of money including tax is printed on the receipt, and the receipt 60 shown in FIG. 6 is issued.

As shown in FIG. 6, in the receipt issued in this embodiment, since the sales detail information of each purchased product is classified and printed together, it is only necessary to glance at the tax type of the purchased product. There is an effect that can be confirmed.

Further, in this embodiment, the sales statement information of the sales commodity registered as a single article is accumulated in the single article work buffer in the order of registration, and after the registration closing key operation, each sales statement information is divided into tax types and printed. . Therefore, if the number of products is within the storage capacity of the single work buffer 31, the registration process can be performed at one time.

It is possible to determine the tax type of the product when a single product work buffer is provided for each tax type and the individual product is registered, and the sales statement information can be stored in the tax type. The number of registrations that can be registered at the same time depends on the storage capacity of the tax type single item work buffer. Therefore, when the number of registrable is set to the same level as that of this embodiment, the number of tax types of buffers equal to the storage capacity of the single work buffer of this embodiment is required, and the cost increases due to an increase in memory capacity. There is.

The present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

[0043]

As described above in detail, according to the present invention, the sales detail information of a registered product for sale is accumulated and stored in a buffer together with a tax classification code indicating the tax type of the product, so that the registration of one transaction can be closed. When this is done, the sales statement information accumulated in this buffer is sorted by tax classification code and printed on the receipt, so the memory capacity does not increase.
It is possible to provide a merchandise sales data processing device capable of classifying sales statement information of merchandise registered for sale by transaction into tax types and printing the receipts together, and issuing a receipt in which tax types can be easily confirmed.
