Then, the CPU 1, the ROM 2, the RAM 3, the clock unit 4, the communication interface 5, the I / O port 8, the keyboard controller 10, the display controller 13, the printer controller 15 and the scanner interface 16 are connected to a bus line such as an address bus and a data bus. Connect at 17, P
It constitutes the control circuit of the OS terminal.

The mode switch 6 is a switch for the operator to select various business modes such as "registration", "check", "payment" and "setting" that can be executed by the POS terminal. Incidentally, the “registration” is a mode of business in which the sales number, the sales amount, etc. of the product registered by the product registration means are processed in the memory and the printer 14 prints / issues a receipt. “Setting” is a mode of operation in which product sales data that has undergone sales processing is totaled in the memory, and the totalized result is printed on recording paper by the printer 14 and output as an inspection report. The “settlement” is a mode of operation in which, like the “inspection”, the result of totaling product sales data is output as a report, and then the processed product sales data in the memory is cleared. "Setting" is a mode of work in which data necessary for executing various works such as "registration" and "settlement" is preset in the memory.

The keyboard 9 is used for the product points, amount of money, and PL.
POS that has various keys such as PLU key, subtotal key, deposit / cash total key, clear key, multiplication key, cancel key, etc. in addition to the numeric keys for entering numerical data such as U code
It is a keyboard dedicated to the terminal.

The operator display 11 is for displaying the name of the registered product, the price, the total amount of the product sales transaction, the change amount, etc. to the cashier who is the operator of the POS terminal. The container 12 is for displaying similar data to the shopper.

The printer 14 prints detailed data such as the PLU code of the registered product, the product name, the price, the total amount of the product sales transaction, the deposit amount, and the change amount on the receipt paper and the journal paper. The receipt paper is the product. It is cut into sales transaction units and issued as a receipt, and the journal paper is wound inside the terminal and stored as a history of product sales transactions.

The scanner 16 optically reads a bar code attached to each product or the like, and the PLU code unique to the product is printed or attached to each product in the form of a bar code.

The POS terminal having the above-mentioned structure has a structure for supporting a mass selling system for the same product.
The PLU table 2 having the area structure shown in FIG.
1, a bulk sale processing table 22, a transaction totalizer 23, and a registration flag memory 24 are formed.

The PLU table 21 corresponds to the product-specific PLU code set for each product, and is set to "1" for the product name of the product, the unit price that is the price per product, and the product to be sold collectively. The set sale flag F is set and stored, and the number of sales and the amount of sale of the product specified by the PLU code are additionally stored.

The collective sale processing table 22 is a collective sale symbol (A, B, C, ... In the present embodiment) for identifying the collective sale target product and P of the collective sale target product.
Corresponding to the LU code, the number of sales points and the selling price at the time of completion of the bulk sale are set and stored, and the number of sales points of the bulk sale target product and the sales number of the bulk sale target product in a unit of transaction of sale with one shopper and The selling prices are summed up, and the number of times of collective selling of the products to be collectively sold and the total discount amount are additionally stored.

The transaction totalizer 23 is an area for totaling the sales amounts of the commodities registered as the commodity sales transaction with one shopper.

The registering flag memory 24 stores a registering flag F which is set to "1" at the start of product registration of a product sales transaction with one shopper and reset to "0" at the end of product registration. This is the area to be stored.

In this POS terminal, the "register" mode is selected by the mode switch 6, and the PLU code converted into the bar code by the scanner 16 is scanned or the keyboard 9 is placed as a product registration means. When the PLU code is keyed in with the number keys and the PLU key, the sale item specified by the PLU code is registered, so that the CPU 1 executes the PLU registration process shown in the flowchart of FIG. .

First, the CPU 1 determines in ST1 whether or not the registration flag F in the registration flag memory 24 is set to "1". Here, when the registration flag F is reset to "0", one item of the merchandise sales transaction with one shopper has been registered, so the registration flag F is set to "1" as ST2. . Further, in ST2, the data of the total number of sales and the amount area of the total sum 23 and the total sale processing table 22 are cleared to “0”. If the registration flag F is set to "1" in ST1, the processing of ST2 and ST3 is not performed because it is the registration of two or more items of the merchandise sales transaction with one shopper.

Next, the CPU 1 executes the PLU sales registration processing at ST4. This process uses the PLU code that is scanned or keyed in the PLU table 2
1 is searched, and the product name, unit price, and bulk sale flag f of the registered product set corresponding to the PLU code are read. Then, the unit price is multiplied by the number of sales points (the multiplier when the multiplier is entered by the numeric key and the multiplication key immediately before entering the PLU code, the multiplier, and when the multiplier is not entered, 1) to sell the registered product. Calculate the amount of money, and PLU table 21
Is a process of adding the number of sales points and the sales amount to the sales point number data and the sales amount data corresponding to the corresponding PLU code.

Next, the CPU 1 adds the sales amount of the registered merchandise to the transaction totalizer 23 in ST5. Also, ST6
Then, the name of the registered merchandise, the sales amount, etc. are displayed on the operator display 11 and the customer display 12.

Next, in step ST7, the CPU 1 checks the bulk sale flag f of the registered merchandise to determine whether or not the registered merchandise is a preset merchandise for bulk sale (commodity determination means). Here, if the bulk sale flag f is reset to "0", the registered product is not a bulk sale target product, and the process proceeds to ST8. In ST8, the PLU code, the product name, the selling price, etc. of the registered product are printed by the printer 14 on the receipt paper and the journal paper. After printing, the PLU registration process this time is completed.

On the other hand, if the batch sale flag f is set to "1" in ST7, the registered product is a product for batch sale, so the process proceeds to ST9. In ST9, the PLU code, the product name, the selling price, etc. of the registered product are printed by the printer 14 on the receipt paper and the journal paper. At this time, the bulk sale symbol corresponding to the PLU code of the registered product is acquired from the bulk sale processing table 22,
This collective selling symbol is printed by attaching it to the upper digit side of the most significant digit of the PLU code. In ST10, the sales amount of the registered product is added to the sales amount data of the registered product corresponding to the PLU code of the registered product in the sales unit processing table 22 (collection sales sales number counting means), and the sales amount of the registered product is added to the sales amount data of the registered product. Is added.

Next, in step ST11, the CPU 1 determines whether or not the bulk sale of the bulk sale target sale products is completed.
That is, the collective selling point data corresponding to the PLU code of the registered product in the collective selling processing table 22 is
It is determined whether or not the result corresponds to a positive multiple of the number of sales points, which is the corresponding condition for the bulk sale (bulk sale determination means). Here, if the bundled sale point data does not match a positive multiple of the bundled sale satisfaction condition point, it is determined that the bundled sale is unsuccessful, and the current PLU registration processing is ended.

On the other hand, if the bundled selling point data coincides with a positive multiple of the bundled selling satisfaction condition score in ST11, it is determined that the bundled selling is successful, and the process proceeds to ST12. ST
At 12, the collective discount price is calculated by subtracting the corresponding collective sell price from the collective sell price data corresponding to the PLU code of the registered product in the collective sell processing table 22. Then, as ST13, the transaction totalizer 2
The collective discount processing is performed by subtracting the collective discount amount from 3. Further, in ST14, the collective discount amount is added to the total discount amount corresponding to the PLU code of the registered product in the collective sale processing table 22, and "1" is added to the establishment count data.

Then, in ST15, the printer 14 prints each piece of information of the collective sale code, the number of conditions for establishment, the collective sale price, and the collective discount amount on the receipt paper and the journal paper (collective discount amount printing control means).

Next, at ST16, the unit price after discount is calculated by dividing the amount obtained by subtracting the collective discount amount from the collective sale amount data corresponding to the PLU code of the registered product in the collective sale processing table 22 by the collective sale establishment condition score. . In this case, when the unit price after discount produces a fraction below the decimal point, rounding is performed by rounding off the fraction below the decimal point (unit price after discount calculation means). After the discounted unit price is calculated in this way, the printer 14 prints the discounted unit price on the receipt paper and the journal paper (post-discount unit price printing control means). At this time, the discounted unit price obtained by rounding the fractional part after the decimal point is indicated by adding "about" before the unit price to indicate that it is an approximate unit price. As for the unit price after discount, which is an integer as a result of calculation by the unit price after discount calculation unit and does not need to be rounded to the right of the decimal point, "about" is omitted. Above,
The PLU registration processing this time is ended.

When the input of the subtotal key is detected after the PLU registration process is completed, the CPU 1 displays and prints the amount data of the transaction totalizer 23 as the subtotal amount. It also calculates the amount of foreign tax and displays and prints the total amount including tax. Next, when the deposit amount is input by the deposit / cash total key, the total amount including tax is subtracted from the deposit amount to calculate the change amount, and the deposit amount and the change amount are displayed and printed. Thereafter, the printer 14 is driven to issue a receipt, the drawer is opened, the registering flag F is reset to "0", and the product sales transaction with one shopper is ended. .

In the present embodiment configured as described above, it is now assumed that the data shown in FIG. 2 is set in the PLU table 21 and the bulk sale processing table 22, respectively. In this state, PLU codes “PLU1”, “PL
For a shopper who purchased a total of 7 items of U4 ”,“ PLU5 ”, and“ PLU6 ”items and 3 items of the PLU code“ PLU2 ”, the cashier“ PLU6 ”,
"PLU2", "PLU1", "PLU5", "PLU"
Assuming that the products are registered one by one in the order of “2”, “PLU2”, and “PLU4”, the collective sale identified by the collective sale symbol “A” is established when the third point of the PLU code “PLU2” is registered. To do. Then, as the receipt, as shown in the print data 41 in the receipt 40 shown in FIG.
En] is established, and the summary discount information indicating that the discount amount is 34 yen is printed. Further, in the next line, as shown in the print data 42, the total amount of the selling price before discount of the items for which the bulk sale is determined to be successful [384 yen]
The amount [350 yen]
[Yen] is divided by the number of sales points [3 points] that are sold together and rounded to the nearest whole number.
16 yen] will be printed in the format of “* (1 116 yen) *”, and with the digits of the price of the registered product and the summary discount amount shifted.

As described above, according to the present embodiment, the price per item after the discount of the products determined to be bundled for the same product is calculated as the unit price after the discount, and the calculated value is calculated. Since the post-delivery unit price is printed on the receipt, the receipt 40 (see FIG. 4) that is printed / issued to the shopper who has completed the bulk sale of the same product has the value of the product for which the bulk sale has been completed. The price per item after drawing is specified. Therefore, since the unit price before discount of the product is printed on the receipt 40, it is possible for the shopper to easily compare the unit price before discount and the unit price after discount, and the service based on the bulk sale method is provided. The degree can be strongly appealed to shoppers. Also, some shoppers calculate the unit price after discount and record it in the household account book, so such shoppers should not have to calculate the unit price after discount. And improve customer service.

Further, in the present embodiment, when rounding the fraction below the decimal point when calculating the unit price after discount,
Since the unit price after the discount is added with "about" at the beginning to clearly indicate that the price is an approximate amount, shoppers will not point out the inaccuracy of the amount. Further, the post-discount unit price is printed on the line next to the corresponding summed discount amount, so that the shopper can easily understand which mass sale unit price after discount. In addition, since the unit price after discount is printed by shifting the digit from the discount amount, it becomes clear that the unit price after discount is not included in the total amount of merchandise sales transactions. In addition, the unit price after discounting is enclosed in parentheses, and the US mark "*" is attached, so the degree of clarity is the highest.

In the above embodiment, the rounding process after the decimal point when rounding off the discounted unit price is rounded down, but it may be rounded off or rounded up.
However, by adopting rounding down, the difference from the unit price before discount becomes large, so it becomes possible to more strongly appeal to shoppers the degree of service by the bulk sale method.
It is convenient.

Further, the above-mentioned one embodiment is a POS terminal which sequentially prints the details such as the product name and price of the registered product on the receipt every time the product is registered.
Immediately, the summary discount information and the unit price after discount are printed, but after the product registration, the details of the registered products are printed together.
In the case of the OS terminal as well, after completion of product registration by inputting a subtotal key or the like, it is determined whether or not the collective sale is successful by referring to the collective sale processing table 22, and when the collective sale is successful, the summary discount information and the unit price after discount are given. The present invention can be applied by being configured to print.

In addition, the printing format of the unit price after discount is not limited to that of the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
