Description

  The present invention relates to a merchandise sales data processing apparatus such as a POS (Point Of Sales) terminal, an electronic cash register, etc., which inputs a bar code attached to a merchandise and processes merchandise sales data based on the bar code data.

  In order to maintain consistency with the JAN code system established as a unified product code so far, barcodes attached to periodicals such as magazines in Japan are published in a two-digit periodical code flag. Consists of a 13-digit bar code that includes a 7-digit publication code that indicates the issue type, type, number of items, etc., a 3-digit price code that indicates the price of the publication, and a 1-digit check digit It had been. In the barcode for the periodicals, the price is a tax-included price to which an amount equivalent to the consumption tax imposed on consumption such as purchase of goods and acceptance of services is added. For this reason, in a POS terminal that reads this type of barcode with a barcode scanner and performs processing such as sales registration of merchandise sales data based on the barcode data, it uses the flag for the read barcode for the periodicals. When the barcode is recognized, price data is acquired from the barcode, and the price data is processed as it is as the price of a product (magazine or the like) to which the barcode is attached.

  However, for example, magazines may be sold after being stored as back numbers for a long time, and the tax rate of the consumption tax may change during that time. It was better to use the price excluding tax. Therefore, in Japan, the barcode system for periodicals is based on the 13-digit main barcode (periodic code code flag [[ 491], etc.), an 18-digit barcode added with a 5-digit add-on barcode is changed to represent a tax-excluded price with 4 digits in the add-on barcode.

  However, barcodes with a new barcode system that includes tax-excluded prices (hereinafter referred to as new magazine barcodes) are only applied to periodicals issued after the implementation date, and are issued before that date. The published periodicals still had the old bar code system bar code (hereinafter referred to as the old magazine bar code) that included the tax-inclusive price corresponding to the tax rate at the time of publication. For this reason, if there is a change in the consumption tax rate in the future, there will be a mix of periodicals as products with items with the old magazine bar code and items with the new magazine bar code. First, it is identified whether the barcode attached to the publication is a new magazine barcode or an old magazine barcode. In the case of a new magazine barcode, the tax-included amount is calculated from the tax-excluded price included in the barcode and the changed tax rate. After calculating the tax-excluded amount from the tax-included price to be applied and the tax rate before the change, the tax-excluded amount is calculated from the tax-excluded amount and the tax rate after the change.

In relation to this, a barcode that automatically identifies whether a barcode read by a barcode scanner is a barcode that includes a tax-excluded price or a barcode that includes a tax-included price, and includes a tax-excluded price. In this case, there is a barcode processing apparatus that calculates a tax-included price from a tax-excluded price and a predetermined tax rate (see, for example, Patent Document 1).
JP 2005-018670 A

  However, the technology of the conventional bar code processing apparatus as described above is in a store where a product with a periodical magazine barcode and a product with a new magazine barcode are mixed. Is applicable if the tax rate equivalent to the consumption tax included in the price data included in the old magazine barcode is the same as the current rate, but after changing the consumption tax rate, There was a problem that the correct tax-included price of periodicals with magazine barcodes could not be obtained.

  Then, when the consumption tax rate is changed, there are three possible operations when selling periodicals with old magazine barcodes.

1. Operation that does not correspond to the tax rate after the change, selling as it is at the price including tax of the price data included in the old magazine barcode.

2. Operation of calculating the body price by hand calculation from the tax-included price in the price data included in the old magazine barcode and inputting it to the POS terminal to obtain the tax-included price after changing the tax rate as an external tax.

3. The operation of calculating the tax-included price after changing the tax rate by hand calculation from the tax-included price in the price data included in the old magazine barcode, and entering it as a change in selling price to the POS terminal.

  However, in the first operation, when the consumption tax rate increases, the store bears the difference, and when the consumption tax decreases, the customer bears the difference, resulting in a large loss. Further, in the second and third operations, manual calculation intervenes, which increases the burden on the sales staff and is inconvenient.

  The present invention has been made based on such circumstances, and the purpose of the present invention is that even if the tax rate of the tax equivalent amount included in the price data included in the barcode of the product is changed, A product sales data processing device that can automatically calculate the tax-included price including the tax-equivalent amount after changing the tax rate of the product, process the sales data of the product at the tax-included price, and can easily handle the tax rate change It is something to be offered.

  The present invention relates to a merchandise sales data processing apparatus that connects a bar code scanner and processes sales data of a merchandise to which the bar code is attached based on the bar code data read by the bar code scanner. Consumption tax rate storage means for storing the current tax rate of consumption tax levied on consumption, and the consumption tax equivalent amount included in the price data included in the barcode attached to the product When the barcode attached to the product is read by the barcode price tax rate storage means and the barcode scanner, the price data acquisition means for acquiring the price data included in the barcode, and the price data acquisition means The price of the item with the barcode from the obtained price data and the tax rate stored in the barcode price tax rate storage means Calculate the tax-included price of the item with the barcode from the main price calculator that calculates the data, the main price data calculated by the main price calculator, and the current tax rate stored in the consumption tax rate storage Tax-inclusive price calculating means, and sales data processing means for processing the sales data of the commodity with the barcode based on the tax-inclusive price calculated by the tax-inclusive price calculating means.

  According to the present invention in which such a measure is taken, even if the tax rate of the tax equivalent amount included in the price data included in the barcode of the product is changed, the tax equivalent amount after the change of the tax rate of the product is included. The tax-included price can be calculated automatically, and the sales data of the product can be processed at the tax-included price. No loss occurs on the store side or on the customer side due to the tax rate change, and the burden on the sales staff increases. It is possible to provide a merchandise sales data processing device that can be easily handled without any problems.

The best mode for carrying out the present invention will be described below with reference to the drawings.
This embodiment is for dealers in which periodicals as products are mixed with periodicals with the old magazine barcode 1 and periodicals with the new magazine barcode 2. This is a case where the present invention is applied to the POS terminal.

  Incidentally, as shown in FIG. 1A, the old magazine barcode 1 is composed of a 13-digit main barcode (excluding T). Among them, the first two digits are a periodicity code flag 1A, which is fixed to [11]. The next five digits are a publication code 1B representing the type of publication, the next two digits are a number code 1C representing the number of the publication of the publication, and the next three digits are The price code 1D represents the price of the publication, and the last digit is a check digit 1E. Here, the price represented by the price code 1D is a price in units of 10 yen, and is a tax-included price to which a tax equivalent amount of consumption tax imposed on consumption such as purchase of goods and service acceptance is added. For example, if the price code 1D is “087”, the tax-included price is 870 yen, and if “100”, the tax-included price is 1,000 yen.

  On the other hand, as shown in FIG. 1B, the new magazine barcode 2 is composed of an 18-digit barcode in which a 5-digit add-on barcode 4 is added to the right side of the 13-digit main barcode 3. Of the main bar code 3, the first three digits are a periodicity code flag 3A, which is fixed at [491]. The remaining 10 digits are the product identification code 3B, with the first digit being a reserve code (magazine = 0), the second to sixth digits being a publication code, the seventh and eighth digits being the month or number, and the nine digits The first is the year and the tenth is the check digit. In addition, among the add-on bar codes 4, the first digit is a spare code, and the remaining four digits are a price code 4A. The price code 4A is a main body price that does not include a consumption tax, and when it exceeds 9,999 yen, it is [0000].

  FIG. 2 is a perspective view showing an external configuration of the POS terminal 20 in the present embodiment. The POS terminal 20 is provided with a keyboard 21, a mode switch 22 and an operator display 23 on the front of the main body, and a customer display 24 on the back. In addition, a printer 25 for printing a receipt is built in the terminal body, and a receipt printed by the printer 25 is discharged from a receipt issuing port 26. The POS terminal 20 is connected to a scanner 27 for optically reading a barcode. In addition, a drawer 28 for storing change or the like is formed integrally with the POS terminal 20.

  The scanner 27 checks whether or not the add-on bar code is decoded when the main bar code data conforming to the 13-digit JAN code system is normally read. If the add-on bar code is decoded, the scanner 27 Both the code and add-on barcode data are transferred to the POS terminal 20. If the add-on barcode is not decoded, only the main barcode data is transferred to the POS terminal 20.

  FIG. 3 is a block diagram showing a main configuration of the POS terminal 20. The POS terminal is provided with a CPU (Central Processing Unit) 31 as a control unit main body. Also, a ROM (Read Only Memory) 32 in which fixed data such as a program is stored in advance, a RAM (Random Access Memory) 33 in which various memory areas for storing rewritable data are rewritable, a current date Data communication between the clock unit 34 for measuring time and the store computer 50 that manages the product file 51 in which product information such as product name and price of the product is set in advance corresponding to the product identification code for each product. A communication interface 35 for controlling the scanner, a scanner interface 36 to which barcode data read by the scanner 27 is input, a mode selection signal from the mode switch 22 and an open command signal to the drawer 28 are output. A keyboard controller 38 for capturing key signals corresponding to operation keys from the port 37 and the keyboard 21; A display controller 39 that displays an image corresponding to display data on the display 23 for the operator, a display controller 40 that displays an image corresponding to the display data on the customer display 24, a printer controller 41 that controls the printing operation of the printer 25, etc. Is provided. The CPU 31, ROM 32, RAM 33, clock unit 34, communication interface 35, scanner interface 36, I / O port 37, and controllers 38 to 41 of various input / output devices are connected by a bus line 42 such as an address bus and a data bus. ing.

  In addition to the numeric keys “0” to “9”, the keyboard 21 is provided with various function keys such as an amount key, a total key, a current key, and a clear key. The money amount key is a key for declaring that the numeric data is money data. The total key is a key for instructing the total output of one transaction. The current total key is a key for declaring that the numeric data is cash payment amount data. The clear key is a key for instructing clearing of a numerical value and cancellation of an error state.

  The mode switch 22 is an operation switch for instructing the CPU 31 to execute a business mode selected and operated from various business modes such as “registration”, “inspection”, and “settlement”. Incidentally, “registration” refers to the process of registering the sales data of the product with the barcode attached to the predetermined memory area of the RAM 33 based on the barcode data read by the scanner 27 and issuing a receipt for each transaction. It is a mode of business that performs etc. “Inspection” is a task of totaling data registered in a predetermined memory area by a “registration” task for each tabulation item, creating sales data for each tabulation item, and printing or displaying the data. “Settlement” is a task of clearing data registered in a predetermined memory area after creating and outputting sales data for each tabulation item as in “inspection”.

In the RAM 33, in addition to the above-described memory area for merchandise sales data registration, in particular, as shown in FIG. 4, the old tax rate m corresponding to the consumption tax included in the price data of the old magazine barcode 1 is set. A tax rate setting memory 61; a current tax rate setting memory 62 in which a current consumption tax rate n is set; a bar code buffer 63 for temporarily storing bar code data received from the scanner 27; and a bar code stored in the bar code buffer 63 Product name memory 64 for storing the product name of the product with the barcode of the code data, body price memory 65 for storing the body price B of the product, tax-included price memory 66 for storing the tax-included price C of the product, An internal tax amount memory 67 for storing the internal tax amount D of the product, an amount totaling unit 68 for summing up the amount of merchandise purchased for one transaction, an internal tax summing unit 69 for summing up the internal tax amount for one transaction, Such receipt buffer 70 which receipt printing data of the transaction amount is temporarily stored is formed.
Here, the current tax rate setting memory 62 constitutes a consumption tax rate storage means, and the old tax rate setting memory 61 constitutes a barcode price tax rate storage means.

  Accordingly, when the CPU 31 receives the barcode data read by the scanner 27 via the scanner interface 36 in the “registration” mode, the CPU 31 starts the barcode input processing shown in the flowchart of FIG.

  First, the CPU 31 stores the barcode data received from the scanner 27 in the barcode buffer 63. Next, the CPU 31 checks the barcode data in the barcode buffer 63. Here, when the first two digits are [11], that is, the flag 1A for the periodicals code of the old magazine barcode 1, the old magazine barcode processing detailed in the flowchart of FIG. 6 is executed. . In contrast, if the first three digits are [491], that is, the flag 3A for the periodicals code of the new magazine barcode 2, the new magazine barcode processing detailed in the flowchart of FIG. 7 is executed. To do.

  Here, the CPU 31 determines whether the price data included in the barcode read by the barcode scanner 27 is data with tax (old magazine barcode 1) or tax-excluded price (new magazine barcode 2). The bar code price discriminating means for discriminating is constituted.

  FIG. 6 is a flowchart specifically showing the contents of the old magazine barcode processing. That is, when entering the old magazine bar code processing, the CPU 31 first analyzes the 13-digit bar code data stored in the bar code buffer 63 as ST (step) 1 and issues a publication corresponding to the product code. The code 1B and the number code 1C are acquired. Further, a price code 1D corresponding to the price A is acquired (price data acquiring means). Then, as ST2, an inquiry is made to the store computer 50 with the publication code 1B and the number code 1C, and the product file 51 is set corresponding to the product code composed of the publication code 1B and the number code 1C. The product name is acquired and set in the product name memory 64.

  Next, the CPU 31 uses the price A derived from the price code 1D and the tax rate m set in the old tax rate setting memory 61 as ST3, and the barcode is attached by the following equation (1). The main price B of the product is calculated (main price calculation means).

Body price B = A × 100 / (100 + m) (1)
Then, the calculated main body price B is set in the main body price memory 65.

  In equation (1), the body price B is rounded after the decimal point. In this case, whether rounding is performed by rounding, rounding by rounding down, or rounding up is set as an option in advance.

  Next, the CPU 31 determines whether the tax rate m set in the old tax rate setting memory 61 as ST4 is equal to the tax rate n set in the current tax rate setting memory 62, that is, included in the old magazine barcode. It is determined whether or not the current tax rate has been changed with respect to the tax rate equivalent to the consumption tax included in the price A (tax rate change determination means).

  As a result, when both the tax rates m and n are equal, that is, when the current tax rate is not changed with respect to the tax rate equivalent to the consumption tax included in the price A included in the old magazine barcode, the CPU 31 In ST5, the price A is set in the tax-included price memory 66 as the tax-included price C of the product with the barcode attached. In ST6, the tax amount is calculated by subtracting the main body price B in the main body price memory 65 from the tax included price C in the tax included price memory 66, and is set in the internal tax amount memory 67.

  On the other hand, if both tax rates m and n are not equal, that is, the current tax rate has been changed with respect to the tax rate equivalent to the consumption tax included in the price A included in the old magazine barcode The CPU 31 uses the main body price B in the main body price memory 65 and the current tax rate n set in the current tax rate setting memory 62 as ST7, and uses the current tax rate n set in the current tax rate setting memory 62 to The tax-included price C for the current tax rate n is calculated (tax-included price calculation means: first tax-included price calculation means).

Tax-included price C = B × (100 + m) / 100 (2)
Then, the calculated tax-included price C is set in the tax-included price memory 66. Also, as ST8, the tax amount is calculated by subtracting the main body price B in the main body price memory 65 from the tax included price C in the tax included price memory 66, and set in the internal tax amount memory 67.

  In the formula (2), the price C including tax is rounded off after the decimal point. In this case, whether rounding is performed by rounding, rounding by rounding down, or rounding up is set as an option in advance.

Thus, if the tax-included price C and the in-tax amount D with respect to the current tax rate n of the product are calculated from the tax-included price data A included in the old magazine barcode 1 attached to the product, the CPU 31 stores the product name memory as ST9. The product name in 64 and the tax-inclusive price C in the tax-included price memory 66 are displayed on the operator display 23 and the customer display 24 (commodity price display means). In ST10, the tax-included price C in the tax-included price memory 66 is set as the sales price of the product with the barcode attached, and sales registration processing is performed in a predetermined memory area of the RAM 33 together with the sales score = 1 (sales data processing means). In ST11, the product name in the product name memory 64 and the tax-included price C in the tax-included price memory 66 are set in the receipt buffer 70. In ST12, the tax-included price C in the tax-included price memory 66 is added to the price totalizer 68 (price summing means). In ST13, the internal tax amount D in the internal tax amount memory 67 is added to the internal tax totalizer 69.
Incidentally, the amount totalizer 68 and the internal tax totalizer 69 are cleared to “0” prior to the start of registration of one commercial transaction. Note that these processes of ST9 to ST13 do not need to be executed in the order of the steps, and can be replaced as appropriate.

  Thereafter, if the CPU 31 clears the barcode buffer 63 in ST14, the old magazine barcode processing is terminated.

  FIG. 7 is a flowchart specifically showing the contents of the new magazine barcode processing. That is, when entering the new magazine barcode process, the CPU 31 first analyzes the data of the main barcode 3 among the 18-digit barcode data stored in the barcode buffer 63 as ST21 and corresponds to the product code. The product identification code 3B to be acquired is acquired. Further, the data of the add-on barcode 4 is analyzed, and the price code 4A corresponding to the price A is acquired (price data acquisition means). Then, in ST22, the store computer 50 is inquired with the product identification code 3B, and if the product name set in the product file 51 corresponding to the product identification code 3B is acquired, the product name memory 64 is set. . In ST23, the price A derived from the price code 4A is set in the main body price memory 65.

  Next, the CPU 31 uses the body price B in the body price memory 65 and the current tax rate n set in the current tax rate setting memory 62 as ST24 to attach the barcode according to the equation (2). The tax-included price C for the current tax rate n of the product is calculated (tax-included price calculating means: second tax-included price calculating means). Then, the calculated tax-included price C is set in the tax-included price memory 66. Also, as ST25, the tax amount is calculated by subtracting the main body price B in the main body price memory 65 from the tax included price C in the tax included price memory 66, and set in the internal tax amount memory 67.

  Thus, if the tax-included price C and the tax-included amount D for the current tax rate n of the product are calculated from the price data excluding tax included in the new magazine barcode 2 attached to the product, the CPU 31 determines the product name as ST26. The product name in the memory 64 and the tax-included price C in the tax-included price memory 66 are displayed on the operator display 23 and the customer display 24 (commodity price display means). In ST27, the tax-included price C in the tax-included price memory 66 is set as the sales price of the product with the barcode attached, and sales registration processing is performed in a predetermined memory area of the RAM 33 together with the sales score = 1 (sales data processing means). In ST28, the product name in the product name memory 64 and the tax-included price C in the tax-included price memory 66 are set in the receipt buffer 70. In ST29, the tax-included price C in the tax-included price memory 66 is added to the price totalizer 68 (price summing means). Further, the internal tax amount D in the internal tax amount memory 67 is added to the internal tax totalizer 69 as ST30.

Each process of ST26 to ST30 does not need to be executed in the order of the steps, and can be replaced as appropriate.
Thereafter, if the bar code buffer 63 is cleared, the CPU 31 ends the new magazine bar code processing.

  The CPU 31 starts the total key input process shown in the flowchart of FIG. 8 when the total keys of the keyboard 21 are operated and input in the “registration” mode.

  First, the CPU 31 determines whether or not a registration flag is set in ST41. When the registering flag is not set, the total key is operated without registering merchandise for one transaction, so a key input error is notified and the current total key input process is terminated.

  When the registering flag is set, the CPU 31 displays the amount data stored in the amount totalizer 68 as ST42 on the operator display 23 and the customer display 24 as the total amount of one transaction ( Transaction total display means). In step ST43, the total amount data of one transaction is stored in the receipt buffer 70 together with the character data “total” indicating the total amount. Further, the amount data stored in the internal tax totalizer 69 as ST44 is stored in the receipt buffer 70 as the internal tax data for one transaction together with the character data “internal tax” indicating the internal tax amount.

  Next, the CPU 31 waits for payment data for the total amount to be input in ST45. Then, if payment data of the payment item and the payment amount is input by the key operation of the numeric key, the current total key, the ticket key, etc. of the keyboard 21, the CPU 31 receives the payment item and the payment amount data as receipt in ST46. Store in the buffer 70. Next, CPU31 judges whether payment was completed as ST47. Here, if the payment amount is insufficient with respect to the total amount, it is determined that the payment has not been completed, and the processing returns to ST45 to wait for additional input of payment data.

  If it is determined that the payment has been completed, the CPU 31 calculates the change amount by subtracting the total amount from the total amount of payment in ST48, and displays it on the operator display 23 and the customer display 24. In ST49, the change amount data is stored in the receipt buffer 70 together with the character data “change” indicating the change. After that, the CPU 31 outputs the data in the receipt buffer 70 to the printer 25 as ST50, and prints and issues a receipt. In ST51, an opening command signal is output to the drawer 28 to open the drawer 28. Thereafter, if the registering flag is reset to “0” in ST52, the current total key input process is terminated.

  As described above, in the POS terminal of the present embodiment, it is included in the price data included in the old magazine barcode 1 separately from the current tax rate setting memory 62 for setting the current tax rate n of the consumption tax in the RAM 33. An old tax rate setting memory 61 for setting the tax rate m corresponding to the consumption tax is provided.

  Price data including the consumption tax equivalent amount of 5% is included in the old magazine barcode 1 attached to the products (periodical publications) currently on sale, and the current tax rate has not changed at this time. Then, the tax rate n in the current tax rate setting memory 62 and the tax rate m in the old tax rate setting memory 61 are the same value.

  Under this condition, when the old magazine barcode 1 is scanned by the barcode scanner 27, the price A of the price data included in the old magazine barcode 1 is the product ( The tax-included price C corresponding to the current tax rate n of the periodicals) is derived, and the sales data of the product is subjected to sales registration processing based on the tax-included price C. Further, the tax-included price C is added to the amount totalizer 68 and displayed on the operator display 23 and the customer display 24.

  On the other hand, when the new magazine barcode 2 is scanned by the barcode scanner 27, the barcode is calculated from the price A of the price data included in the new magazine barcode 2 and the tax rate n of the current tax rate setting memory 62. The tax-included price C corresponding to the current tax rate n of the product (periodical publication) with “” is calculated, and the sales data of the product is subjected to sales registration processing by this tax-included price C. Further, the tax-included price C is added to the amount totalizer 68 and displayed on the operator display 23 and the customer display 24.

  Thereafter, when the consumption tax rate is changed, the data in the current tax rate setting memory 62 is updated to the changed tax rate data. That is, the tax rate n in the current tax rate setting memory 62 and the tax rate m in the old tax rate setting memory 61 are different values.

  Under this condition, when the old magazine barcode 1 is scanned by the barcode scanner 27, the price of the price data included in the old magazine barcode 1, that is, the price A corresponding to the pre-change tax rate m Based on the tax rate m in the old tax rate setting memory 61, the body price B of the product (periodical publication) with the barcode is calculated, and the current price of the product is calculated from the body price B and the tax rate n in the current tax rate setting memory 62. A tax-included price C corresponding to the tax rate n is calculated, and sales data of the product is registered for sales based on the tax-included price C. Further, the tax-included price C is added to the amount totalizer 68 and displayed on the operator display 23 and the customer display 24.

  On the other hand, when the new magazine barcode 2 is scanned by the barcode scanner 27, the price A and the current tax rate setting memory included in the new magazine barcode 2 are the same as when the consumption tax rate is not changed. The tax-included price C corresponding to the current tax rate n of the product (periodical publication) with the barcode is calculated from the 62 tax rate n, and the sales data of the product is registered for sales using this tax-included price C. . Further, the tax-included price C is added to the amount totalizer 68 and displayed on the operator display 23 and the customer display 24.

  Thus, according to the present embodiment, even when the current tax rate n is changed with respect to the tax rate m corresponding to the consumption tax included in the price data included in the old magazine barcode 1, the old magazine barcode is changed. By scanning 1, the product with the old magazine barcode 1 can be sold at a tax-inclusive price corresponding to the current tax rate n. In addition, with respect to a product to which the new magazine barcode 2 is attached, it is possible to sell the product at a tax-inclusive price corresponding to the current tax rate n by simply scanning the new magazine barcode 2. Therefore, even if there is a change in the consumption tax rate, the store does not bear the difference and the customer does not bear it. Further, complicated manual calculation by the salesperson is unnecessary, and the burden on the salesperson does not increase.

  In addition, the price data displayed on the operator display 23 and the customer display 24 may be the product with the old magazine barcode 1 or the product with the new magazine barcode 2. Both are tax-inclusive prices C corresponding to the current consumption tax rate n. Therefore, when displaying a price on a price tag or an advertisement for a consumer, it corresponds to a total amount display method that requires display of a total amount of payment including a consumption tax equivalent amount. Similarly, in the case of the product with the old magazine barcode 1 and the product with the new magazine barcode 2, the tax-included price C corresponding to the consumption tax rate n is calculated in both cases. And is displayed as the total amount of one transaction, so that it corresponds to the total amount display method.

  The present invention is not limited to the merchandise sales data processing device (POS terminal) for the periodicals barcodes 1 and 2 attached to the periodicals, but a barcode including the tax-included price is attached. The present invention can be similarly applied to a device for processing sales data of a product, for example, a POS terminal, an electronic fee scale and the like.
