Displays the price and product name of the product entered from CPU1.
It displays the total amount etc. calculated by. The printer 5 prints out the product name, price, total price of the purchased products, etc., and issues it as a receipt. The P-ROM 6 stores an operating program for the CPU 1 based on a flowchart shown in FIG. 1, which will be described later. The memory 7 stores data input from the keyboard 2 and data for each product.

FIG. 3 is a diagram showing the key arrangement of the keyboard 2 shown in FIG. 2.

As shown in the figure, the keyboard 2 is provided with a registration mode setting switch 21, a numeric keypad 22, a clear key 23, a product key 24, a subtotal key 25, and a deposit/cash total key 26.

The registration mode setting switch 21 is used to set the ECR to a registration mode for product registration and payment processing, and the numeric keypad 22 is used to input numerical data such as product codes and product amounts. clear key 23
is for clearing numerical data etc. input from the numeric keypad 22. The product key 24 is used to input a product code, and the subtotal key 25 is used to add up the amount data input from the numeric keypad 22. The deposit/cash key 26 is operated when inputting the amount received from a customer and calculating change.

FIG. 4 is a diagram showing the configuration of the memory 7 shown in FIG. 2.

The memory 7 includes an input data memory 71, a product code memory 72, a registered data memory 73, a discount memory 74, a purchase total memory 75, and an individual item memory table 76.

The input data memory 71 stores function key codes and input position data. For example, the function key code becomes "01" when the product key 24 is operated, and "02" when the scanner 3 is used.
becomes. The input number data at this time is the product code. Also, this funxicon key code is subtotal key 2
When you operate 5, you will hear “1o” and press deposit/cash key 2.
When 6 is operated, it becomes "11".

The product code memory 72 stores the product code input from the keyboard 2 or scanner 3. The product name, registered price, and discount rate corresponding to the product code stored in the product code memory 72 are transferred from the individual product memory table 76 and stored in the registered data memory 73. The registered amount is an amount registered in advance for each product. The discount memory 74 stores the discount amount calculated from the registered amount and the discount rate. The purchase total memory 75 stores the total amount of products purchased by the customer.

The individual product memory table 76 stores the product code, product name, registered price, discount rate, sales amount, and total discount amount for each product. The sales amount is the sum of the registered amounts for the amount purchased by the customer, and the total discount amount is the sum of the discount amount for the amount purchased by the customer.

Input data memory 71, product code memory 72, registration data memory 73, discount memory 74, and purchase total memory 75 are used as work memories.

Next, the operation of the ECR of this embodiment will be explained using the flowchart shown in FIG.

First, at the start of the process, predetermined work memories, that is, the input demos 71, the product code memory 72, the registered data memory 73, the discount memory 74, and the purchase total memory 75 are initialized (step S1). Next, the product code is input from the keyboard 2 or scanner 3 into the input data memory 71 as input number data. Normally,
The product code is obtained by scanning the barcode attached to each product with the scanner 3. However, if the scanner 3 is defective, the product code is entered using the numeric keypad 22 of the keyboard 2 as shown in FIG. Product key 24
An operation of pressing is performed (step 82).

When the product key 24 is pressed or the product code is input by the scanner 3, the input data memory 71
Transfer the input number data to the product code memory 72 (
Steps 83.84).

Furthermore, based on the product code in the product code memory 72,
Narch the individual item memory table 76 <Step S5
). If a product code that matches the product code in the product code memory 72 exists in the single item memory table 76, the corresponding product code, the corresponding product name, registered amount, and discount rate are transferred to the registration data memory 73 (step 86.87). If there is no product code in the individual item memory table 76 that matches the product code in the product code memory 72, the process proceeds to error processing (step 86).

Next, it is determined whether the discount rate stored in the registered data memory 73 is 0 (step 88).

If the discount rate is not O, use the registered amount and discount rate in the registered data memory 73 to calculate the discount amount as follows: discount amount - registered amount x discount rate/100 (Step S9.510), and calculate the discount amount. The value is stored in the discount memory 74 (step 51).
1). Then, the printer 5 prints the product name and registered amount corresponding to the input product code on the purchase receipt (step 512), and also prints the discount rate and discount amount on the purchase receipt (step $13). Further, the amount obtained by subtracting the discount amount from the registered amount is displayed on the display 4 (step 514).

Next, the amount obtained by subtracting the discount amount from the registered amount is added to the total purchase amount in the purchase total memory 75 for -+II customers (
Step 515). Then, in order to manage sales for each individual item, the registered amount is added to the sales amount corresponding to the input product code in the individual item memory table 76.
Further, the discount amount stored in the discount memory 74 is added to the total discount amount (step 816).

If the discount rate is 0 in step S9, step 817
The printer 5 prints the product name and registered amount corresponding to the input product code, and the registered amount is displayed on the display 4.
(step 818). Then, add the registered amount to the total purchase amount in the purchase total memory 75 in step 8.
19) Add the registered amount to the sales amount corresponding to the input product code in the individual item memory table 76 (step 820).

FIG. 6 shows an example of an operator's operation and a printed receipt corresponding to the operator's operation.

In this example, product code 49400403 and product code 49322004 indicate Mild Seven and snack food, respectively, and the discount rate for Mild Seven is 0, and the discount rate for snack food is specified as 10%.

In the above embodiment, the case where the present invention is applied to the ECR has been described, but the present invention can be applied to various transaction processing devices other than the ECR.

[Effects of the Invention] As described above, according to the present invention, since the discount rate is stored for each product, discount processing is automatically performed even if the discount rate differs for each product.

Therefore, the burden on the operator is reduced and detailed price reduction management becomes possible.
