DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial Application Field] The present invention relates to a tax-exempt product in which sales tax is levied at a fixed tax rate, a tax-exempt product which is sold with unit price including tax at a fixed tax rate, and no tax is levied. Electronic cash register or POS (point-of-sale information management) used at stores that sell tax-exempt products
The present invention relates to a product sales data processing device such as a terminal.

[0002]

2. Description of the Related Art In a conventional product sales data processing apparatus of this type, sales detailed information of products registered for sale by product registration means is printed in receipt order. Then, a mark indicating a pre-set tax type (for example, “Inside” for tax-inclusive items, “Non” for non-taxable items, and no non-taxable items) is printed on a receipt in accordance with the corresponding sales statement information. Tax types were distinguished.

[0003]

By the way, the customer who wants to check the tax amount imposed by the purchase of the foreign tax-exempt product, the so-called foreign tax amount, obtains the total amount of the foreign tax-exempt product from the receipt and multiplies it by a certain tax rate. The outside tax amount was calculated. For this reason, it is troublesome to pick up the information of the tax-exempted product on the receipt in which the sales detailed information of the sales registered product is printed in the registration order.

Therefore, the present applicant provides a buffer for accumulating and storing sales details information of a product for each tax type. When sales registration of the product is performed by the product registration means, the tax type of the product is determined, and the corresponding tax is determined. The sales details information of the sales registered product is accumulated and stored in the type buffer, and when the registration closing of one transaction is performed by the registration closing means, the sales details information stored in each buffer is sequentially printed for each buffer. (Japanese Patent Laid-Open No. 4-344)
996). This makes it possible to issue a receipt classified by tax type. However,
In this device, it was necessary to have a plurality of buffers for each tax type. In addition, since it is not clear to what extent shoppers will purchase products of the same tax type in one transaction,
Each buffer had to have necessary and sufficient storage capacity. For this reason, there is a technical problem that the required memory capacity is significantly increased and the cost is increased. The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a product sales data that can issue a receipt that allows easy confirmation of a tax type without causing a problem of high cost due to an increase in memory capacity. It is intended to provide a processing device.

[0005]

According to the present invention, sales data of merchandise registered for sale by merchandise registration means is sales-registered in a storage section. In a merchandise sales data processing device that prints and issues sales details information and total sales information of merchandise that has been subjected to sales registration processing, the sales details information of the merchandise sales registered by the merchandise registration means indicates the tax type of the merchandise. One buffer that accumulates and stores together with the tax classification code, and when one transaction is closed by the registration closing means, the tax classification code sequentially matches for each tax classification code from the detailed sales information that is stored and stored in the buffer. And a tax type detailed information printing means for extracting sales detailed information and printing it on a receipt.

[0006]

According to the present invention having such a configuration, when the sale of a product is registered by the product registration means, the detailed sales information of the product is accumulated and stored in a buffer together with a tax classification code indicating the tax type of the product. You. When registration closing of one transaction is performed by the registration closing means, sales detailed information having the same tax classification code for each tax classification code is sequentially extracted from the sales detailed information stored in the buffer and printed on a receipt. You. As a result, on the receipt issued to the customer, the detailed sales information of the product purchased by the customer is printed after being sorted into the tax type, so that the tax type can be easily confirmed. In this case, the number of buffers for storing and storing the sales statement information may be one irrespective of the tax type, so that the memory capacity may be smaller than providing a buffer for each tax type.

[0007]

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
A control unit main body 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 store the POS
The main memory of the terminal is constituted, and fixed data such as the control program is set in the ROM 11 in advance.
In M12, an area for setting variable data necessary for data processing of the CPU 10, an area for temporarily storing data generated by the data processing of the CPU 10, and the like are formed. The clock circuit 13 counts 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, ROM 11, RAM 1
2 and the clock circuit 13 are connected by a bus line 14. 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 an input / output control unit such as the scanner controller 20 are connected.

The I / O port 15 receives a signal from the mode switch 21 and notifies the CPU 10 of the signal. In addition, a drive signal is output to the drawer opening device 22 according to a command from the CPU 10 to open a drawer (not shown) for storing cash and the like.

The mode switch 21 is used to select various business 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 registered in the storage unit, and when registration closing of one transaction is performed by the registration closing means, the registration of the product registered in the transaction is performed. This is a business mode in which sales statement information and total sales information are printed on a receipt and issued. “Inspection” is a business mode in which the contents of the storage unit subjected to the sales registration processing by “Registration” are printed out on a recording sheet and a sales summary report is issued. "pay off"
Is a business mode in which the contents of the storage unit subjected to the sales registration processing by “register” are printed out on a recording sheet, a sales summary report is issued, and then the storage unit is cleared. "Setting"
Is a job in which data necessary for executing various job modes such as "registration", "inspection", and "payment" is set in the storage unit in advance.

The communication interface 16 uses the PO
It controls data transmission / reception 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 section, a unit price, and a tax classification code are set in advance 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 set as the product to be excluded from tax, the tax classification code “2” is set as the product to be included in tax, and the tax classification is set. Code "3" is a tax-exempt product.

The keyboard controller 17 includes a numeric key for inputting numerical data, a PLU key for indicating that the numerical data is a single item code, and a registration closing key as registration closing means for instructing registration closing of one transaction. A display controller 18 controls a keyboard 26 provided, a display controller 18 controls a display 26 that displays the names and sales amounts of products registered for sale and a total amount of one transaction, and a printer controller 19 controls a printer that prints receipts. The scanner controller 20 controls a barcode scanner 28 that optically reads a barcode attached to a product.

Here, each product has a unique single-item code, and most of the products are bar-coded and pasted or printed. And POS
The terminal reads and inputs the barcode of the product with the barcode scanner 28 or inputs the numeric key of the keyboard 25 and the PLU.
The product is registered for sale by inputting the single item code with the key. Here, the bar code scanner 28, the numeric keys of the keyboard 25 and the PLU key constitute a product registration unit.

The RAM 12 functions as a storage unit for performing sales registration processing of sales data of products registered for sale by the product registration means. As shown in FIG. 3, the RAM 12 stores single item sales detailed information including a single item code, a single item name, a unit price, a sales number, a sales amount, and the like of a product registered for sale as a tax classification code indicating a tax type of the product. A single work buffer 31, which accumulates and stores, a counter area 32 for a registration number counter n, a reading counter r, and a tax division counter t, a flag area 33 for a registering flag F,
Various areas such as a print buffer 34, a transaction total unit area 35, a foreign tax target total amount area 36, a foreign tax amount area 37, and a tax total amount area 38 are formed.

In the state where the "registration" mode is selected by the mode switch 21,
It is programmed to execute the processing shown in the flowchart of FIG.

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

If the registering flag F is not set to "1", it is the first single item registration of one transaction.
In ST3, the registration flag F is set to "1". In step ST4, the transaction total unit area 35, the foreign tax target total amount unit area 36, the foreign tax amount area 37, and the tax total amount area 38.
And the single item work buffer 31 is cleared. Further, in ST5, the registered number counter n of the counter area 32 is set.
After resetting to "0", the process proceeds to ST6.

If the registering flag F is set to "1" in ST2, since the second item after the first transaction is registered as a single item, the process proceeds to ST6 without performing the processes of ST3 to ST5.

In ST 6, a single item information inquiry message is created using the input single item code as a search key, and transmitted to the file processor 23 through the communication interface 16.
The file processor 23 that has received the inquiry message searches the single item file 29 and returns the single item information of the single item name, link section, unit price and tax classification code corresponding to the single item code for which the inquiry was made. Received C
The PU 10 acquires the product sales data with the sales price data as the unit price in the single item information and the sales point data as “1”,
The merchandise sales data is subjected to sales registration processing in the RAM 12 for each link section, for example. In step ST7, the sales amount data is added to the transaction totalizer area 35. Next, in step ST8, the tax classification code in the single item information is checked to determine whether or not the product for sale is a product subject to foreign tax. If the tax classification code is "1", the item is a tax-exempt product, and the sales amount data is added to the tax-exempt amount total device area 36 in ST9.
If the tax classification code is "2" or "3", the product is not a tax-exempt product, and thus the process of ST9 is not performed.

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

Thereafter, in step ST12, it is determined whether or not the registration closing key has been input.
Return to and process the single item registration for the next product for sale. That is, ST1, ST2, ST6, ST7, ST8, (ST
9), the processing of ST10 and ST11 is executed.

If the key input of the registration closing key is detected in ST12, the external sales amount set in advance to the total sales amount of the external taxable product added in the external taxable total amount area 35 in ST13. A tax rate (for example, 3%) is multiplied to calculate an external tax amount.
Is added to the total sales price of the sold product, and the total tax included is calculated, and the total tax included is displayed on the display 26.

Next, in step ST14, the sales statement information stored and stored in the single item work buffer 31 is rearranged according to the tax classification code and printed on the receipt by the printer 27 (tax type statement information printing means).

Next, at ST15, the total transaction area 3
5 is a subtotal and the total taxable area is 3
The contents of No. 5 are printed on the receipt by the printer 28 together with the tax amount calculated in step ST13 and the tax-included total amount as the tax-exempt amount.

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

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

Next, in step ST23, the single work buffer 31 is set.
The tax classification code is read from the area (in this case, the first area) corresponding to the value of the read counter r. And ST2
At 4, it is determined whether or not the tax classification code matches the value of the tax classification counter t.

If they match, the product detail information is read from the area corresponding to the value of the read counter r of the single item work buffer 31 in ST25 and converted into receipt print data, and then set in the print buffer 34. Then, in ST26, the contents of the print buffer 34 are
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 processing of ST26 is not performed.

Next, if 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 equal to or smaller than the value of the registration number counter n, there is data that has not been read yet in the single item work buffer 31 with the tax division counter r at the predetermined value. Return, ST27
The process up to is repeated. As a result, of the single item sales detailed information accumulated and stored in the single item work buffer 31, all information whose tax classification code is equal to the value of the tax classification counter r is extracted and printed on receipt.

In this way, when the value of the read counter r becomes larger than the value of the registration number counter n in ST28, S
Proceeding to T29, the tax division counter t is counted up by "+1". Then, if it is confirmed in ST30 that the value of the tax division 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 division counter t has exceeded "3", the sales detail information accumulated and stored in the single item work buffer 31 is the tax-exempt product with the tax division code "1". Since the products are sorted in the order of the tax-inclusive product with the tax classification code “2” and the tax-exempt products with the tax classification code “3”, and the receipt printing is performed by the printer 27, the printing process is terminated.

Next, the operation and effect of the embodiment constructed as described above will be described based on specific examples.

Now, a customer has purchased "Orange Juice" and "Ice Cream" as tax-exempt products, "Weekly Magazine" and "Beer" as tax-exclusive products, and "Prepaid Card" as tax-exempt products, respectively. Suppose you purchased 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 accumulates and stores the single item sales detail information and the tax classification codes of the respective products in the order of registration.

Thereafter, when the cashier declares the end of the registration of one transaction by operating the registration closing key, first, the external tax amount is calculated from the total amount of the products subject to the external tax, and further, the total amount including the tax is calculated and displayed. As displayed on the display 26, the customer pays for the total amount including tax.

Further, a single item sales statement information printing process of the tax type is executed. That is, first, the sales detail information of “orange juice” and “ice cream”, which are the tax-exempt products with the tax classification code “1”, is read from the single item work buffer 31 and printed on the receipt. Next, sales details information of “weekly magazine” and “beer”, which are tax-included products with the tax classification code “2”, are read from the single item work buffer 31 and printed on receipt. Finally, the detailed sales 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 on the receipt.

After that, the subtotal amount, the foreign tax target amount, the foreign tax amount,
The receipt including the total amount including tax is printed, and a receipt 60 shown in FIG. 6 is issued.

As shown in FIG. 6, in the receipt issued in this embodiment, the detailed sales information of each purchased product is classified into a tax type and printed collectively, so that a glance of the tax type of the purchased product can be obtained. There is an effect that can be confirmed.

Further, in this embodiment, the sales details information of the sales product registered as a single product is stored in the single product work buffer in the order of registration, and after the registration closing key is operated, each sales details information is classified and printed according to tax type. . Therefore, if the number of products is within the storage capacity of the single item work buffer 31, registration processing can be performed at once.

It is also possible to provide a single item work buffer for each tax type, determine the tax type of the item at the time of single item registration, and store the detailed sales information in the tax type. The number of items that can be registered at the same time depends on the storage capacity of the single work buffer for each tax type. Therefore, when the number of registers that can be registered is the same as that of the present embodiment, the number of buffers equal to the storage capacity of the single work buffer of the present embodiment is required by the number of tax types, and the cost increases due to an increase in the memory capacity. There is.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the spirit of the present invention.
