BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register for mass retail stores such as supermarkets.

0002

2. Description of the Related Art As a conventional electronic cash register of this type, one having a PLU (Price Look Up) registration function is known. This product has a product table inside or outside in which the product name, unit price, etc. are preset according to the product code of each product, and the product code is input via an input device such as a keyboard or barcode scanner. Then, the product table is searched, the product name and unit price corresponding to the input product code are read out, and the sales amount of the product for which the product code is input is calculated from the unit price and the number of items sold, and the sales are registered. At this time, the display is configured to display the product name and sales amount almost in real time.

[0003] By the way, at mass retail stores such as supermarkets, customers usually walk through the store with a basket provided in the store, place all the products they want to purchase in the basket, and then go to the checkout area equipped with an electronic cash register. go. Then, the clerk at the checkout area prepares an empty basket, takes out the products received from the customer one by one, enters the corresponding product code using a keyboard or scanner, and then transfers them to the empty basket. After entering the product codes for all the products in the cart received from the customer, the user operates the subtotal key on the keyboard. Then, the total price of all the products purchased by the customer is displayed on the display, and payment is received from the customer and a receipt is issued. In addition to detailed product data such as product names and sales amounts of all products purchased by the customer, the total price of all products, total number of items, etc. are printed on the receipt.

[0004] Therefore, the customer can discover the store clerk's registration error by checking the product that the store clerk has placed in an empty basket, as well as the product name and sales amount displayed on the display. Also,
After receiving the receipt, it is possible to discover the registration error from the total number of items printed on the receipt and the number of purchased items.

[0005]

[Problem to be Solved by the Invention] However, for example, when inputting a barcoded product code using a barcode scanner, if a store clerk makes a registration mistake of reading the barcode of one product twice in succession. Since there was no change in the display contents, it was difficult for customers to notice the registration error. In addition, in this case, when the store clerk notices a registration error, he cancels the one item that was registered just before, but from the customer's perspective, the meaning of the cancellation operation is unclear and he is unsure whether it has been registered correctly. . As mentioned above, it is possible to confirm that there was a registration error after the receipt has been issued, but even if the registration error is noticed after the customer has left the store, it is difficult to prove it, causing trouble.

[0006] Therefore, the present invention aims to provide an electronic cash register that can display and output the total number of points registered up to that point during the registration of products purchased by a single customer, and that can reliably detect registration errors during product registration. It is something.

[0007]

[Means for Solving the Problems] The present invention accumulates and stores the number of sales items and sales amount of sales items inputted by a product registration operation in a cumulative total memory for each customer, and In an electronic cash register that prints out the total points and total amount for one customer stored in the cumulative memory on a receipt, a score display section for displaying the total points stored in the cumulative memory and a closing key are input operated. Total score reading means for reading the total score stored in the cumulative memory at a predetermined timing before the total score is read out, and total score display control means for displaying the total score read by the reading means on the score display section. It is.

[0008]

[Operation] In an electronic cash register employing such a method, while a customer is registering a product to be purchased, the total number of points registered up to that point is displayed on the point display section. Therefore, if the content displayed on the score display section and the number of products already registered by the store clerk are different, it can be confirmed that a registration error has occurred.

[0009]

Current total key 14, multiplication key 15 for instructing multiplier input
, various keys such as a cancel key 16 for instructing cancellation of the most recently registered product are provided.

Both the displays 5 and 6 are capable of displaying two lines of 16 characters per line, as shown in FIG.
The characters are used as the name display section 21, the 6 characters on the upper right side are used as the amount display section 22, the 6 characters on the lower left side are used as the total purchase score display section 23, and the 10 characters on the lower right side are used as the total purchase amount. It is used as the display section 24.

FIG. 5 is a block diagram of an electronic cash register, in which a CPU (central processing unit) 31 constituting the main body of the control unit is connected via a bus line 32 to a ROM (read only memory) 33 and a RAM ( random access memory) 34, a clock circuit 35 that measures the current date and time;
an I/O port 37 to which a selection signal of the mode switch 4 is input and a drive signal to a drawer opening device 36 for opening the drawer 8; a keyboard controller 38 to which key signals from the keyboard 2 are input;
A scanner interface 39 to which a barcode reading signal is input from the scanner 8, a printer controller 41 that drives and controls a printer 40 for printing on receipts, etc., a display controller 42 that drives and controls both the displays 5 and 6, etc. Each part is connected.

The ROM 33 stores in advance program data and the like for the CPU 31 to control the business mode selected by the mode switch 4.

As shown in FIG. 4, the RAM 34 has the following information:
A product table 51 in which the product name and unit price are preset in accordance with the product code of each product and also stores the total number of sales points and total sales amount for each product; a temporary buffer 52 that temporarily stores the latest data for each data item; one person A registration flag F1 is set (1) during the registration of a product purchased by a customer, and a multiplier flag F2 is set in response to a multiplier input.
Various memory areas are formed, such as a flag memory 53, a point counter 54 for accumulating the number of items purchased by one customer, and an amount totaler 55 for accumulating the amount of items purchased by one customer.

When the power is turned on and the predetermined initialization process is completed, the CPU 31 starts the control shown in FIG. 6. That is, it waits for a barcode reading operation (scanning) to be performed by the scanner 8 in ST (step) 1 or for a key input operation on the keyboard 2 to be performed in ST2. Then, when a barcode reading signal is input via the scanner interface 39 in ST1, the scanning process shown in FIG. 7 is executed. That is, when the "registration" mode is selected by the mode switch 4, the registration flag F1 of the flag memory 53 is set to "1", and the input barcode is converted to a product code and the The product name and unit price corresponding to the product code are read from the product table 51 and stored in the temporary buffer 52 together with the product code. Next, the multiplier flag F2 in the flag memory 53 is checked. Here, if the flag F2 is reset to "0", since a single item is registered, the sales data is stored in the temporary buffer 52 with the number of sales items set to "1" and the unit price set as the sales amount. Then, the number of sales points is added to the point counter 54, and the sales amount is added to the amount totalizer 55. On the other hand, the multiplier flag F2 is “1”
If it is set to , there are a plurality of registrations, so the sales data is stored in the temporary buffer 52 with the sales amount as the multiplier input immediately before, and the amount obtained by multiplying the unit price by the multiplier as the sales amount. Then, the number of sales points is added to the point counter 54, and the sales amount is added to the amount totalizer 55. At this time, set the multiplier flag F2 to “0”
Reset to .

Thereafter, the sales data is cumulatively registered in the total score area and total amount area corresponding to the input product code of the product table 51. In addition, the name display section 21 of both displays 5 and 6 displays the product name read from the product table 51, the price display section 22 displays the unit price read out in the same manner, and the total purchase score display section 23 displays the count value of the point counter 54. The stored values of the amount totalizer 55 are respectively displayed on the purchase total amount display section 24. Furthermore, the printer 40 is driven and controlled,
The product name and unit price, as well as the number of sold items and sales amount registered in the total sales area of the product table 51 are printed out on a receipt or the like, and the process returns to the control shown in FIG. In addition, mode switch 4
If a business mode other than the "registration" mode is selected, an error will occur.

On the other hand, when a key signal is input via the keyboard controller 38 in ST2, the CPU 31 determines the type of the key signal. When it is confirmed that the key signal input as ST3 is the key signal generated by the key input of the multiplication key 15, the multiplication key processing shown in FIG. 8 is executed. In other words, the mode switch 4
If “Register” mode is selected, press number key 11.
Check to see if numerical data has been assigned. If the number has been assigned, the multiplier flag F2 of the flag memory 53 is set to "1" and the assigned numerical data is stored in the temporary buffer 52 as a multiplier. Thereafter, the multiplier is displayed in the name display areas 21 of both the displays 5 and 6, and the process returns to the control shown in FIG. It should be noted that if a business mode other than the "registration" mode is selected by the mode switch 4, and if numerical data is not entered, an error will occur.

[0019] The key signal input in ST2 is transmitted to ST4.
When it is confirmed that the key signal is generated by key input of the cancel key 16, the cancel key process shown in FIG. 9 is executed. That is, when the "registration" mode is selected by the mode switch 4, it is checked whether the registration flag F1 in the flag memory 53 is set to "1". And if set, product table 5
Since the cancellation of the sales data registered immediately before is instructed in step 1, the number of sales points stored in the temporary buffer 52 is subtracted from the point counter 54, and the sales amount is subtracted from the amount totalizer 55. Further, the number of sold items and the sales amount are subtracted from the sales total area corresponding to the product code stored in the temporary buffer 52 of the product table 51. After that, the message "Trikeshi" is displayed on the name display section 21 of both displays 5 and 6, the count value of the point counter 54 is displayed on the purchase total score display section 23, and the stored value of the amount totalizer 55 is displayed on the purchase total amount display section 24. are displayed respectively. Furthermore, the printer 40 is driven and controlled to perform cancellation printing on a receipt or the like, and the process returns to the control shown in FIG.

Note that if a business mode other than the "registration" mode is selected by the mode switch 4, key processing corresponding to the business mode is executed. Further, if the registration flag F is reset to "0", it is determined as an error.

[0021] The key signal input in ST2 is transmitted to ST5.
When it is confirmed that the key signal is generated by key input of the deposit/cash total key 14, the deposit/cash total key process shown in FIG. 10 is executed. That is, when the "registration" mode is selected by the mode switch 4, it is checked whether the registration flag F1 in the flag memory 53 is set to "1". If it is set, it is declared that the registration is closed by cash payment, so the change is calculated by subtracting the value stored in the totalizer 55 from the payment amount.
The message "Tsurisen" is displayed on the name display sections 21 of both displays 5 and 6, and the calculated amount of change is displayed on the amount display sections 22. In addition, in the above-mentioned change calculation, if numerical data is set using the numeric key 11 just before inputting the deposit/cash total key 14, that numerical data is used as the payment amount, and when no numerical data is set, the payment amount is set as the payment amount. In this case, the value stored in the amount totalizer 55 is set as the payment amount. Next, the printer 40 is driven and controlled to display the total purchase points (score counter 54) on the receipt, etc.
count value) and the total purchase amount (value stored in the amount totalizer 55), the deposited amount and change are printed out, and a receipt is issued from the receipt issuing port 3. Further, an opening drive signal is output to the drawer opening device 36 to open the drawer 8 forward. Thereafter, the registration flag F1 is reset to "0", the point counter 54 and the amount totalizer 55 are cleared, and the process returns to the control shown in FIG.

Note that if a business mode other than the "registration" mode is selected by the mode switch 4, key processing corresponding to the business mode is executed. Further, if the registration flag F is reset to "0", it is determined as an error.

In this embodiment configured as described above, when the barcode of a product is scanned by the scanner 9 in the "registration" mode, the barcode is converted into a product code and the product name and unit price corresponding to the product code are displayed. It is read from the product table 51. If a multiplier is input using the number key 11 and the multiplication key 15 immediately before scanning, that multiplier is set as the number of sales items, and if no multiplier input is performed, "1" is set as the number of sales items. The sales amount (=unit price x number of items sold) is calculated. Then, the number of sales items and sales amount are displayed in the product table 51.
The total is registered in the total area corresponding to the relevant product code. In addition, the point counter 54 counts up by the number of items sold, and the sales amount is added to the amount totalizer 55, and the contents of the point counter 54 and the total amount are displayed on the cashier display 5 and the customer display 6 together with the product name and unit price. The contents of the container 55 are displayed.

Here, the point counter 54 and amount totalizer 55 are cleared by the previous customer's operation of the closing key (deposit/total key 14). That is, the point counter 54 and the amount totalizer 55 function as a cumulative memory for summing up and storing the number of sales items and sales amount for each customer, which are input through the product registration operation. Then, the contents of the cumulative memory, that is, the total number of points registered and the total amount of money registered up to now for one customer are displayed on both the displays 5 and 6.

[0025] Therefore, in the case of a store such as a mass merchandiser such as a supermarket, which operates in such a way that out of all the products purchased by one customer, the products that have been scanned are moved to another basket, the customer is transferred to another basket. Number of products purchased and customer display 6
Compare the total number of registered points displayed in , and if they do not match, it can be determined that a registration error has occurred.

[0026] For example, a registration error in which the barcode of one product is read twice often occurs. Since the total number of registered points increases by 2 points, both customers and store staff can easily discover registration errors. If such a mistake is made, the store clerk operates the cancellation key 16 to delete the sales data that was just registered, but if he does so, the total registration points displayed on both displays 5 and 6 will be equal to the amount of the cancellation. Since the number is reduced to match the number of items in the cart, the customer can confirm the validity of the cancellation operation and will not feel anxious.

Furthermore, according to this embodiment, the total amount of registration is displayed together with the total number of points registered so far during product registration, so that the key operation of the subtotal key 13, which was required before the operation of the close key, can be performed. There are also advantages to being able to omit it.

In the above embodiment, the contents of the point counter 54 are displayed on the displays 5 and 6 at any time when the product is registered. However, if the number of purchased items is small, there is less risk of a registration error occurring. For example, the point counter 54
If the content exceeds "10", it may be displayed. Further, a score display section may be provided independently.

[0029]

[Effects of the Invention] As described in detail above, according to the present invention, the total number of registered points up to that point can be displayed and output while a customer is registering a product to be purchased, and registration errors can be reliably discovered during product registration. We can provide electronic cash registers.
