The mode switch 16 is provided with "registration",
A switch for selecting various business modes such as “check”, “payment”, and “setting” and instructing the CPU 11 to execute them. Here, “registration” means that when sales registration of a customer-purchased product is performed by inputting a single item code, registration processing is performed for each product in a predetermined area of the RAM 13 based on sales data of the customer-purchased product, and 1 is entered by inputting a closing key. In this mode, when the end of the transaction with the shopper is declared, the printer 14 prints and issues a receipt recording the details of all the products purchased by the shopper. “Inspection” is a task of totalizing the contents of a predetermined area in which sales data of each product has been registered by a registration task and outputting the result as a sales report.
The “payment” is a mode of a business in which the contents of a predetermined area are totaled and output as a sales report, and then the predetermined area is cleared, similarly to the inspection business. “Setting” is a business mode in which data necessary for executing a registration business or the like is set in the RAM 13 in advance.

In the POS terminal 4 having such a configuration, as shown in FIG. 8, the RAM 13 stores single item registration information including items of a single item code, a sales point, a sales amount, a coupon code, and a product coupon discount. A single item registration buffer 31 for storing the order of registration for each transaction, a coupon registration buffer 32 for storing coupon registration information including coupon code, discount information, coupon name and type flag items for each transaction, Transaction total amount memory 3 for storing the total amount of goods registered for sale in

In the POS terminal 4, when a bar code of a single item code attached to each product is scanned and input by the bar code scanner 26 while the "registration" mode is selected by the mode switch 16, The program is configured so that the CPU 11 executes the single item code input process shown in the flowchart of FIG.

That is, when starting the single item code input processing, the CPU 11 first determines whether or not the registering flag is set in the flag memory 35 as ST (step) 1. If the registering flag has been reset (0), one of the products purchased by the shopper is
Since the single item code of the dot is input, the single item registration buffer 31 is cleared as ST2. In addition, the flag memory 3
In step 5, a registering flag is set (1). If the registering flag has already been set (1) in ST1, since the single item codes of the second and subsequent items of the product purchased by the shopper have been input, the processes in ST2 and ST3 are not performed.

Next, an inquiry message for single item information is created using the single item code input as a search key in ST4, and the inquiry message is transmitted from the communication interface 15 to the POS controller 5 via the communication line 6. Then, upon receiving the inquiry message, the POS controller 5 searches the single item file 7 with the single item code in the inquiry message, and detects a single item record including the single item code.
Inquiry PO of the single item record via communication line 6
Since the terminal 11 responds to the S terminal 4, the CPU 11 of the POS terminal 4 that has transmitted the inquiry message
It waits for a response of the single item record from the S controller 5.

Then, within a predetermined period of time, the PO
When the single unit record is responded from the S controller 5 and received by the communication interface 15, as ST6, the single unit code in the single unit record and the number of sales points (the multiplier has been input by the numeric key and the multiplication key before the single unit code is input). In this case, the multiplier, if the multiplier is not input, 1) and the sales amount calculated by multiplying the sales points by the unit price in the single item record are stored in the single item registration buffer 31 in the order of registration. In step ST7, the unit name and the sales amount in the unit record are displayed on the operator display 21 and the customer display 22. This is the end of the single item code input process.

If no single item record is returned after a certain period of time in step ST5, a message notifying that the single item information is not set for the item registered for sale in step ST8 is sent to the operator. The information is displayed on the display 21 and the customer display 22, and the single item code input process of this time is ended.

In the POS terminal 4, the coupon code printed on each of the coupon tickets 1 and 2 by the barcode scanner 26 and the barcode of discount information are input by scanning while the “registration” mode is selected. Then, the program is configured so that the CPU 11 executes the coupon code input process shown in the flowchart of FIG.

That is, when starting the coupon code input process, the CPU 11 first determines whether or not a coupon flag is set in the flag memory 36 as ST1. If the coupon flag has been reset (0), the coupon code and the discount information of the first coupon ticket presented by the shopper have been input, so that S
As T2, the coupon registration buffer 32 is cleared. Also, a coupon flag is set in the flag memory 36 (1).
I do. If the coupon flag has already been set (1) in ST1, since the coupon codes and discount information of the second and subsequent coupons 1 and 2 presented by the shopper have been entered, the processing in ST2 and ST3 is performed. No processing is performed.

Next, in ST4, an inquiry message of coupon information is created using the input coupon code as a search key, and the inquiry message is transmitted from the communication interface 15 to the POS controller 5 via the communication line 6. Then, the POS controller 5 that has received the inquiry message searches the coupon file 7 with the coupon code in the inquiry message, and when a coupon record including the coupon code is detected, the POS controller 5 transmits the coupon record via the communication line 6. Since the response is made to the inquiry source POS terminal 4, the CP of the POS terminal 4 that transmitted the inquiry message
U11 waits for a response of the coupon record from the POS controller 5 as ST5.

Then, within a predetermined period of time, the PO
When the coupon record is responded from the S controller 5 and received by the communication interface 15, whether or not the current date measured by the clock unit 14 is within the validity period (start date to end date) in the coupon record as ST6. Judge. Then, if it is confirmed that the current date is within the validity period, the coupon code, coupon name and type flag in the coupon record and the discount information input by scanning in the coupon record are stored in the coupon registration buffer 32 in the order of registration in ST7. Store. In step ST8, the coupon name is displayed on the operator display 21 and the customer display 22, and the current coupon code input processing ends.

If the coupon record is not responded even after the lapse of a predetermined time in ST5 and if the current date is out of the validity period in ST6, the coupon cannot be used in ST9. Is displayed on the operator display 21 and the customer display 22, and the current coupon code input processing ends.

Here, the barcode scanner 26 includes a single item code, which is a product identification code of a product to be sold and registered as one transaction, and a coupon code, which is a ticket identification code of a discount ticket used in one transaction. Function as a code input means for inputting a password. Also, the single item registration buffer 31 functions as a registered item information storage unit that stores sales information of the item for which the single item code, which is the item identification code, has been input by the barcode scanner 26, which is a code input unit. Function as a discount ticket information storage unit for storing discount information of a discount ticket to which a coupon code as a ticket identification code is input by a barcode scanner 26 as a code input unit.

Further, the POS terminal 4 operates the keyboard 19 with the "registration" mode selected.
Is configured, the CPU 11 executes a total key input process shown in the flowchart of FIG. Incidentally, the total key is a key that functions as total output instruction means for instructing the total output of one transaction.

That is, when starting the total key input processing, the CPU 11 firstly sets the flag memory 3 as ST1.
It is determined whether or not the registration flag is set in 5. If the registering flag is reset (0), it is an erroneous operation in which the total output of the transaction has been instructed without registration of the product sold as one transaction, so that the input of the total key is regarded as an error, and The process ends.

If the registering flag has been set (1) in ST1, it is determined in ST2 whether a coupon flag has been set in the flag memory 36 (discount ticket determining means). Here, if the coupon flag has been reset (0), since the total output of the transactions in which the coupon is not used has been instructed, the total transaction amount is calculated and displayed as ST3. Specifically, once the transaction total amount memory 33 is cleared, the single item registration information stored in the single item registration buffer 31 is sequentially read from the top. Then, the sales amount of the read single item registration information is sequentially added to the transaction total amount memory 33. Thus, when the sales amount of the final single item registration information is added to the transaction total amount memory 33, the transaction total amount memory 33 stores the transaction total amount. Therefore, the total transaction amount is displayed on the operator display 21 and the customer display 22 (transaction processing means without discount ticket).

Thereafter, in ST4, in response to the end of the transaction with one shopper being declared by inputting the closing key, closing processing such as opening the drawer and issuing a receipt is executed.
The closing process includes a process of registering the single item registration information stored in the single item registration buffer 31 in a predetermined area of the RAM 13 for each product. Thereafter, if the registering flag is reset (0) from the flag memory 35 in ST5, the current total key processing ends.

On the other hand, if the coupon flag has been set (1) in ST2, the total output of the transactions using the coupon has been instructed, and after clearing the coupon discount memory 34 in ST6, At ST7, the coupon registration information stored in the coupon registration buffer 32 is divided into coupon registration information of a product coupon with a type flag of “0” and coupon registration information of a total coupon with a type flag of “1”. The coupon registration information of the product coupon is sorted first, and the coupon registration information of the total coupon is rearranged in descending order of the discount.
After the rearrangement, the read counter n is temporarily reset to "0" in ST8, and the read counter n is counted up by "1" in ST9. Then, as ST10, the coupon registration information (hereinafter, referred to as n-th coupon registration information) in the order corresponding to the count value of the read counter n is read from the coupon registration buffer 32 (discount information reading means).

Here, if the n-th coupon registration information can be read from the coupon registration buffer 32 in ST11, it is determined in ST12 whether the coupon registration information is information on a commodity coupon or information on a total coupon. , From the type flag of the coupon registration information.
If the type flag is “0”, that is, the coupon registration information of the product coupon, the product coupon discount processing specifically shown in FIG. 12 is executed.

That is, an inquiry message of the target single item code is created using the coupon code of the n-th coupon registration information as a search key, and this inquiry message is transmitted to the communication interface 15.
To the POS controller 5 via the communication line 6. Then, the POS controller 5 that has received the inquiry message searches the coupon target product file 8 with the coupon code in the inquiry message, and detects a target product record including this coupon code, and searches the target product record for the inquiry source. Of the POS terminal 4 that has transmitted the inquiry message
11 waits for a response of the target product record from the POS controller 5.

Then, within a predetermined period of time, the PO
When the target product record is returned from the S controller 5 and received by the communication interface 15, it is checked whether the single product registration information having the target single product code in the record exists in the single product registration buffer 31. Then, when the corresponding single item registration information exists, it is determined whether or not a plurality of the corresponding single item registration information exists. Then, when there are a plurality of items, the single item registration information having the largest sales amount is selected as the single item registration information of the discount target product by the product coupon. If there is only one,
The single item registration information is used as the single item registration information of the discount target product by the product coupon.

Thereafter, a coupon discount is obtained based on the discount information of the n-th coupon information. Specifically, the coupon discount amount is acquired using the value of the discount information as the discount rate for the sales amount of the discount target product. After obtaining the coupon discount amount in this way, the single item registration information of the discount target product,
The coupon discount is set together with the coupon code of the n-th coupon information. Further, the coupon discount is added to the coupon discount memory 34, and the commodity coupon discount processing is terminated (commodity discount ticket discount processing means).

When there is no response of the target single item record within a certain period of time, or when there is a response of the target single item record but there is no single item registration information having the target single item code in the record, A message indicating that the commodity coupon specified by the coupon name in the n-th coupon registration information cannot be used is displayed on the operator display 2.
1 and the display 22 for the customer, and the merchandise coupon discount processing ends.

On the other hand, if the type flag of the n-th coupon registration information is "1" in ST12 of FIG. 11, that is, the coupon registration information of the total coupon ticket, the total coupon discount shown in FIG. Execute the process.

That is, first, the total transaction amount before the discount by the total coupon is calculated. Specifically, once the transaction total amount memory 33 is cleared, the single item registration information stored in the single item registration buffer 31 is sequentially read from the top. Then, the sales amount of the read single item registration information is sequentially added to the transaction total amount memory 33. And
The sales amount of the final single item registration information is stored in the transaction total amount memory 3
After adding to 3, the transaction total amount memory 33
From the coupon discount memory 34.

By doing so, the transaction total amount memory 33 stores the transaction total amount before the discount by the total coupon ticket, and then, based on the discount information of the n-th coupon registration information, the coupon discount amount. To get. Specifically, the value of the discount information is obtained as it is as the coupon discount. When the transaction total amount before the discount and the coupon discount amount are thus obtained, the two are compared. If the coupon discount is less than the total transaction amount, the discount is possible. Therefore, the coupon discount is added to the coupon discount memory 34, and the total coupon discount processing is terminated (total discount ticket value). Processing means).

On the other hand, when the coupon discount amount is equal to or greater than the total transaction amount, since the discount is not possible, a message notifying that the total coupon ticket specified by the coupon name of the n-th coupon registration information cannot be used is transmitted to the operator. The total coupon discount processing is ended by displaying the information on the display for customer 21 and the display for customer 22.

In step ST12 of FIG. 11, the type flag of the n-th coupon registration information is checked. If the commodity coupon discount processing or the total key input processing is executed according to the state of the type flag, the process returns to ST9. , The read counter n is counted up by "1". Then, when the n-th coupon registration information is read from the coupon registration buffer 32, the type flag of the n-th coupon registration information is checked, and the commodity coupon discount processing or the total key input processing is performed according to the state of the type flag. Execute. That is, the coupon registration information is read out sequentially from the coupon registration buffer 32, and if the coupon registration information is information on a product coupon, a product coupon discount process is executed. If the coupon registration information is information on a total coupon, Execute the total coupon discount processing.

When it is confirmed in step ST11 that the n-th coupon registration information does not exist in the coupon registration buffer 32, the total transaction amount after the discount of the coupon ticket is calculated and displayed. Specifically, once the transaction total amount memory 33 is cleared, the single item registration information stored in the single item registration buffer 31 is sequentially read from the top. And
The sales amount of the read single item registration information is sequentially added to the transaction total amount memory 33. Then, after the sales amount of the final single item registration information is added to the transaction total amount memory 33, the amount of the coupon discount memory 34 is subtracted from the transaction total amount memory 33. By doing so, the transaction total amount after the coupon discount is stored in the transaction total amount memory 33, and this transaction total amount is displayed on the operator display 21 and the customer display 22.

Thereafter, in response to the end of the transaction with one shopper being declared by inputting the closing key, the drawer is opened.
Execute transaction closing process such as receipt issuance. The closing process includes a process of registering the single item registration information stored in the single item registration buffer 31 and the information of the product coupon stored in the coupon registration buffer 32 in a predetermined area of the RAM 13 for each product. Thereafter, if the registering flag and the coupon flag are reset (0) from the respective flag memories 35 and 36, the current total key processing is terminated.

In the present embodiment configured as described above, the product "AAAAA" (unit code zzzzz1) having a unit price of 100 yen and the product "Ame BBB" having a unit price of 120 yen are provided.
B "(single item code zzz2), and the shopper who purchases one item at a time receives both items" Ame AAAA "and" Ame BB ".
BB "is a 5% discount target product coupon and 1
A total of 3 for each of the total coupons of 00 yen discount and 200 yen discount
Assuming that a number of coupons are presented, the cashier operating the POS terminal 4 will be able to provide each product “Ame AAAA”,
Bar code (single item code) attached to "Ame BBBB"
And the barcode (coupon code, discount information) printed on each coupon ticket,
Scanning is input in step 6. Then, the single item registration information buffer 31 and the coupon registration buffer 3 of the RAM 13
2 stores the data shown in FIG. Incidentally, FIG. 14 shows that the merchandise is scanned and input in the order of "AAAAA" and "Ame BBBB", and the coupon is a total coupon coupon of 100 yen discount, a product coupon coupon of 5% discount, and 200 yen value. It is an example of data when scanning input is performed in the order of discount coupons.

Thereafter, the cashier inputs the total key and instructs the total output of one transaction. Then, the coupon registration information stored in the coupon registration buffer 32 is sorted, the coupon registration information of the 5% discounted product coupon ticket is stored in the top area, and then the coupon registration information of the 200 yen discount total coupon ticket Is stored, and then the coupon registration information of the 100 yen discount total coupon ticket is stored.
