[Problems to be Solved by the Invention] As described above, in the conventional product sales data processing device of this type, by sequentially registering the products purchased by one customer, the combination conditions of set sales products set in advance are processed. It is automatically determined whether or not this holds true, and if it holds, a predetermined discount is given. For this reason, in this type of device equipped with a screen display, each time a customer registers a product to purchase, the name of the registered product, the number of units sold, etc. are sequentially displayed in a list. Even if the combination condition is satisfied and a discount is given, the display contents regarding the registered products do not change, and there is a problem in that the total value of the prices of each registered product differs from the actual total price.

[0004] Accordingly, the present invention makes it possible to switch the display regarding the combined products to the display regarding the corresponding set sale product when a combination condition for set sale products is established by sequentially registering the products purchased by one customer. , it is an object of the present invention to provide a product sales data processing device that can improve practicality by making correspondence between display content regarding registered products and the actual total price.

[0005]

[Means for Solving the Problems] The present invention provides a display device having a screen capable of simultaneously displaying the names and sales numbers of products registered for sale for a plurality of products, and a display device that is attached to each single sale product and set sale product. A product file that sets and stores at least a name and a unit price corresponding to the product code of the set product, a set product table that stores and stores each product code of the single sales product to be combined in correspondence with the product code of the set product, and the product. A code input means, an input buffer for storing the product code and sales quantity input by this input means for one customer, and a product code set in the set product table based on each product code stored in this input buffer. set sales determining means for determining whether or not a combination is established; and quantity subtracting means for subtracting the number of sold items corresponding to the applicable product code from an input buffer by the number of established items when the determining means confirms that the combination is established. , a code deletion means for deleting from the input buffer the product code whose sales quantity has become zero by the subtraction means; and a code deletion means for deleting from the input buffer the product code whose sales quantity has become zero by the subtraction means; a set replacement means for storing the product code stored in the input buffer; a product information display control means for reading the name corresponding to the product code stored in the input buffer from the product file and displaying the list on the display screen together with the number of units sold; A total amount calculation means for reading the unit price corresponding to the product code from the product file and calculating the total amount from the unit price and the corresponding sales quantity, and a total amount for displaying the total amount calculated by this calculation means on the screen of the display device. This is a product sales data processing device including an amount display control means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a product sales data processing apparatus for fast food restaurants will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of the apparatus according to the present invention, in which the product code of each product is preset in a processor section 1 that constitutes the main body of the control section and operates based on a preset program. In addition to a plurality of product keys 21 as a means of inputting product codes, a number key 22 is used to enter numerical data such as the number of units sold, a clear key 23 is used to clear the number and clear errors, and a number key 23 is used to input numerical data such as the number of units sold. a keyboard 2 equipped with various function keys such as a close key 24 for instructing the end of registration of products registered for sale; and a screen display device capable of displaying a list of names and sales quantities of a plurality of products registered for sale as well as a subtotal price. 3, a printer 4 that prints the name of the product registered for sale, sales amount, number of items sold, total amount, etc. on receipt paper and issues a receipt;
A memory section 5 provided with various memory areas such as a product file 51, a set product table 52, an input buffer 53, and a subtotal memory 54 are connected to each other.

As shown in FIG. 2, the product file 51 includes names, unit prices, and "1" for products to be sold as a set, corresponding to the product code assigned to each product handled at the store.
It stores each information set in the set flag F set in ``, and also has an area for the cumulative number of sales items and sales amount. There are single sales products that are sold, and set sales products that are sold as a set by combining different single sales products such as "set m" and "set n."

As shown in FIG. 3, the set product table 52 sets and stores each product code of the single sales product to be combined in correspondence with each product code of the set sales product.

The input buffer 53 sequentially stores the product codes and sales quantities of products purchased by one customer as shown in FIG. 4, and the total amount of products purchased by this one customer is stored in the subtotal memory. 54.

The processor 1 is programmed to execute the process shown in FIG. 5 when one of the product keys 21 of the keyboard 2 is inputted. That is, the product code preset in the inputted product key 21 and the sales quantity (if a number has been entered using the number key 22 immediately before, that value is taken as the number of products);
If the number has not been assigned, the number is set to "1") are stored in the input buffer 53 in the order of input. Further, the name, unit price, and set flag F corresponding to the product code are read from the product file 51. Then, the name and number of units sold are displayed on the screen display 3. At this time, if this is the customer's first product registration, the display is cleared once and then displayed. When registering a second or subsequent item, it will be displayed in addition to the previous display.

Next, the unit price read out is multiplied by the number of units sold to calculate the sales amount, and the sales amount is added to the subtotal memory 54. Then, the contents of the subtotal memory 54 are displayed on the screen display 3 together with the name, number, etc.

Next, the read set flag F is examined. Here, if the flag F has been cleared to "0", the registration is for a product that is not eligible for set sale, so this key processing is terminated.

On the other hand, if the flag F is set to "1", the contents of the set product table 52 and the input buffer 53 are compared because the product is registered for set sale. Then, it is determined whether the combination of product codes set in the set product table 52 is established based on the product code stored in the input buffer 53 (
method for determining set sales). Here, if this is not true, this key processing is terminated.

[0016] When a combination of product codes is established, the sales quantity corresponding to the product code corresponding to the combination is subtracted by "1" from the input buffer 53 (quantity subtraction means).
. Here, for products whose sales quantity has become "0", the corresponding product code and sales quantity are deleted from the input buffer 53 (code deletion means). Thereafter, the set product code for which the combination has been established and the number of established items "1" are stored in the input buffer 53. At this time, if the same set product code is already stored in the input buffer 53, the sales quantity corresponding to that set product code is added by "1".

Next, the names corresponding to the respective product codes stored in the input buffer 53 are read out from the product file 51 and displayed in list form on the screen display 3 along with the number of units sold (product information display control means). At this time, the display contents up to that point are cleared.

Next, the unit price corresponding to each product code stored in the input buffer 53 is read from the product file 51, and a subtotal amount is calculated based on the unit price and the corresponding sales quantity, and is stored in the subtotal memory 54. (total amount calculation means). Then, the subtotal amount is displayed on the screen display 3 together with a list of names and numbers (total amount display control means).

After that, the contents of the set product table 52 and the contents of the input buffer 53 are compared again, and the combination of product codes set in the set product table 52 is established using the product codes stored in the input buffer 53. It is determined whether or not this holds true, and if it holds true, the same process as above is repeated. If this is not true, this key processing is terminated.

[0020] In this way, when the registration of all the products purchased by one customer is completed and the closing key 23 is inputted, the processor 1 is programmed to execute the process shown in FIG. That is, the name and unit price corresponding to each product code stored in the input buffer 53 are read from the product file 51, and product detail data consisting of the product name, unit price, number of units sold, and sales amount is created for each product. Then, the number of units sold and the sales amount of each product are recorded in the product file 51.
Addition processing is performed to the cumulative sales area. It also drives and controls the printer 4 to sequentially print out each product detail data and the total amount in the subtotal memory 54 on a receipt paper to control receipt issuance. Thereafter, the input buffer 53 and subtotal memory 54 are cleared, and this key processing is ended.

Next, the effects of the apparatus of this embodiment constructed as described above will be explained. For convenience of explanation, it is assumed that data shown in FIGS. 2 and 3 are set in advance in the product file 51 and set product table 52, respectively.

[0022] Now, one customer has two “hamburgers” and
When purchasing one each of "coffee,""cola," and "french fries," the store clerk first enters "2" using the number keys 22, then the product codes "01" and "1."
Each product key 21 of "0", "11", and "20" is input in sequence. At this point, the contents of the input buffer 53 are as shown in FIG. 4, and the subtotal amount is 900 yen. Further, the display screen of the screen display device 3 is as shown in FIG.

[0023] At this time, a combination of set sales products "set m" (hamburger, coffee, french fries) is established. Therefore, the product code "0" in the input buffer 53 is
The sales quantity corresponding to "1" becomes "2". Also, the product code "10" and the product code "20" are input from the input buffer 53.
' will be deleted. As a result, the subtotal amount becomes 850 yen, which means that a discount of 50 yen has been given. Further, the display screen of the screen display 3 changes as shown in FIG. 8 based on the contents stored in the input buffer 53. Note that in FIG. 8, the mark [*] indicates that the product has been replaced with a set product.

Thereafter, the clerk operates the closing key 23. As a result, the printer 4 issues a receipt as shown in FIG. 9 based on the contents stored in the input buffer 53, and hands it to the customer.

As described above, according to the present embodiment, when a preset combination condition is established by registering a single sale product and the combination is switched to sales of a set sale product, the display 3 displays the corresponding information. The display of the single sold product will be deleted, and the name of the corresponding set sold product will be additionally displayed in its place. Therefore, the sum of the prices of the products whose names are displayed on the display 3 always matches the subtotal amount displayed on the display 3, eliminating the problem of customer distrust.

[0026]Furthermore, since the detailed data of the set sold product is printed on the receipt, and the detailed data of the corresponding individual sold product that has actually been registered is not printed, there is no need to print the discount amount due to the establishment of the set sale. Receipts can be simplified.

[0027] In the above embodiment, when the product registered by key input of the product key 21 is a product to be sold as a set, it is determined each time whether or not the set sale is established. The stored contents of the input buffer 53 are investigated in accordance with the input, and it is determined whether or not a set sale is established, and if the set sale is established, the stored contents of the input buffer 53 are rewritten in the same manner as in this embodiment. Good too.

[0028]

Effects of the Invention As described in detail above, according to the present invention, when a combination condition for set sales products is established by sequentially registering the products purchased by one customer, the display regarding the products to be combined is displayed for the corresponding set. It is possible to provide a product sales data processing device that can switch to a display related to sales products, can match display content related to registered products with the actual total price, and can improve practicality.
