[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to product sales data processing devices such as electronic cash registers and POS (point of sale) terminals, and particularly relates to mix and
The present invention relates to an improvement of a device capable of registering and processing bulk sales of products called the match (hereinafter abbreviated as M&M) method.

0002

[Prior Art] In supermarkets, for example, if you purchase three chocolates at a unit price of 200 yen, you can get a discount of 50 yen and sell them for 550 yen. In some cases, a sales method is adopted in which the products are sold at a price lower than the total price to provide better service to the customer, and this sales method is called the M&M method.

[0003] Conventional product sales data processing devices capable of registering and processing such bulk sales are equipped with counters that count the number of sold products in one transaction for each product designated as bulk sales. It is known that the counter is updated every time a product is registered, and when the count value reaches a predetermined number, it is determined that a bulk sale has been completed and a discount is processed.

[0004]Furthermore, a file memory is provided for storing the total number of units sold and total sales amount for each product, and from the contents of this file memory, for example, daily sales results can be managed for each product. .

[0005]

[Problem to be Solved by the Invention] However, in the conventional product sales data processing device equipped with the file memory described above, although it is possible to grasp the total number of sold products for which bulk sales are specified, it is difficult to understand the total number of products sold at a discount due to bulk sales. It was not possible to manage the number of items. Therefore, there is a problem in that necessary data such as the sales ratio of the number of products sold in bulk to the total number of products sold in bulk cannot be obtained.

[0006] Therefore, the present invention is capable of managing the total number of sold items of products designated for bulk sale as well as the number of times bulk sales are established for each product, and the necessary data such as the sales ratio of the number of bulk sales to the total number of sold items can be managed. The purpose is to provide a product sales data processing device that can be easily obtained.

[0007]

[Means for Solving the Problems] The product sales data processing device of the present invention includes a product code input means for inputting a product code assigned to each product, the total sales quantity of each product, and products designated for bulk sale. a first counting means for counting the number of times a bulk sale has been completed for each product code; a second counting means for counting the number of sold products in one transaction of products designated for a bulk sale for each product code; total sales quantity updating means for updating the total sales quantity corresponding to the input product code counted by the first counting means when the code is input; a code discriminating means for discriminating whether or not the input product code is sold in bulk, and a second counting means counts sales corresponding to the input product code when it is determined by the discriminating means that the input product code is for a product designated for bulk sale. a sales quantity updating means for updating the number of products; a bulk sale determining means for determining whether a bulk sale has been established for each product based on the contents of a second counting means updated by the updating means;
If this judgment means determines that a bulk sale is established, the first
and updating means for updating the number of times a bulk sale has been completed corresponding to the product code of the product for which the bulk sale has been completed, which is counted by the counting means.

[0008]

[Operation] According to the present invention having such a structure, the first counting means counts the total number of sold items of each product and the number of times a bulk sale of a product designated for bulk sale is completed for each product code. Further, the second counting means counts the number of sold items in one transaction of the items designated for bulk sale by item code.

[0009] Here, when the customer inputs the product code of the product to be purchased using the product code input means, the total number of sold items corresponding to the input product code counted by the first counting means is updated. Further, when a product code for a bulk sale product is input, the number of sold items corresponding to the input product code counted by the second counting means is also updated.

[0010] When it is determined from the contents of the second counting means that a bulk sale has been established, the number of times a bulk sale has been established corresponding to the product code of the product that has been sold in bulk, counted by the first counting means, is updated.

[0011] Therefore, necessary data such as the sales ratio of the number of products sold in bulk to the total number of products sold in bulk can be easily obtained from the contents of the first counting means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a POS terminal will be described below with reference to the drawings.

FIG. 1 is a block diagram of the POS terminal in this embodiment, and 11 is a CPU (central processing unit) that constitutes the main body of the control section. This CPU 11 has a built-in arithmetic circuit, a memory control circuit, etc., and executes various arithmetic processing based on input data, and also stores program data etc. for the CPU 11 to control various parts via a bus line 12. A ROM (read only memory) 13 and a RAM (random access memory) 14 in which various memory areas used for data processing by the CPU 11 are formed are operated.

[0014] Also, a communication interface 15 that controls data transmission and reception performed with a higher-level controller connected via a transmission path, a keyboard controller 17 to which key signals from a keyboard 16 are input, and a display 18.
a display controller 19 that drives and controls the printer 20 to display characters, etc. corresponding to the display data; and a printer controller 21 that drives and controls the printer 20 to print receipts, etc.
and an I/O port 22 via the bus line 12.
It is connected to PU11.

The I/O port 22 has power on/off controls.
A signal from a mode switch 23 for controlling off and selecting various business modes such as "registration,""accounting," and "setting," and a signal from a barcode scanner 24 for reading barcodes are input, respectively. It also outputs an opening drive signal to the drawer 25 for storing cash and the like.

The keyboard 16 is provided with various keys such as a number key, a code key, a subtotal key, a close key, and a clear key, which are necessary for executing each of the above-mentioned tasks. Here, it is possible to input the product code assigned to each product by inputting a combination of the number key and the code key. Further, some products have product codes printed as barcodes or affixed as barcode labels, and for such products, the product code can be input by reading the barcode with the barcode scanner 24. . That is, the keyboard 1
6 and the barcode scanner 24 function as a product code input means for inputting a product code attached to a sales product.

In the RAM 14, as shown in FIG. 2, the product name and unit price are preset in correspondence with the product code of each product, and in the case of a product designated for bulk sale, it is set to "1". M&M flag area 31a
, a product file (the first
Counting means) 31, the number of units sold in bulk and the data on the amount sold are preset in accordance with the product code of the product designated as bulk sale, and the number of units sold in one transaction of the product designated as bulk sale is counted. The bulk sale product table (where the area 32a is formed)
A second counting means) 32 is provided. Also, 1
A sales amount totalizer 33 for storing the total sales amount in a transaction, a discount amount totaler 34 for storing the total discount amount in one transaction, and the like are provided.

The CPU 11 is programmed to execute the product registration process shown in FIG. 3 with the mode switch 23 selecting the "registration" mode.

That is, when the product code of the product to be sold is input via the barcode scanner 24 or the keyboard 16 as ST (step) 1, the product file 3
The product name and unit price corresponding to the input product code are read from 1. Then, the product file 31 uses the unit price as the sales amount.
The sales amount is accumulated in the contents of the total sales amount area 31b corresponding to the input product code, and the contents of the total sales number area 31c corresponding to the input product code are updated by "+1" (total sales number updating means). Also, sales amount totalizer 33
Add the above sales amount to the contents of and add the result to the summator 3.
Restore to 3.

[0020] Next, as ST2, the product file 3 is
Check the M&M flag corresponding to the input product code of 1 (
code discrimination method). Here, if the flag is reset to "0", the product is registered for which bulk sale is not specified, so the product name, sales amount, etc. are displayed on the display 18, and the product code, product name, etc. are displayed on the printer 20. The product details data such as the sales amount is printed out on a receipt or the like, and this process is completed.

On the other hand, if the M&M flag corresponding to the input product code is set to "1" in ST2, the input product code in the bulk sale product table 32 is registered as a product designated for bulk sale. The contents of the corresponding sales quantity area 32a are updated by "+1" (sales quantity updating means).

Next, in ST3, the number of products corresponding to the input product code in the bulk sale product table 32 is compared with the contents of the sales number area 32a (bulk sale determination means). If the contents of the sales quantity area 32a are an integral multiple of the number of sold items, it is determined that the bulk sale is completed using the M&M method, and the discount amount is calculated from the following equation (1). Discount amount = unit price of the applicable bulk sale product x number of items sold - amount paid... (1)

Then, the above discount amount is subtracted from the content of the total sales amount area 31b corresponding to the input product code in the product file 31, and the above discount amount is added to the content of the discount amount totalizer 34, and the addition results are It is stored again in the totalizer 34. Further, the contents of the M&M success count area 31d corresponding to the input product code in the product file 31 are updated by "+1" (a success count updating means).

Thereafter, as in the case of products that are not designated for bulk sale, the product name, sales amount, etc. are displayed on the display 18, and the printer 20 prints the product details data such as the product code, product name, sales amount, etc. on a receipt, etc. , and then end this process.

On the other hand, if the content of the sales quantity area 32a is not an integral multiple of the sold quantity in ST3, the M&M
It is determined that the bulk sale is unsuccessful according to the method, and the process proceeds to the above-mentioned display and printing process.

Further, when the subtotal key of the keyboard 16 is input after executing the above-described product registration process, the CPU 11 is instructed to output the total of one transaction, and therefore, from the contents of the sales amount totalizer 33, The content of the discount amount totalizer 34 is subtracted to calculate the total amount of one transaction, and the display 18
and print it on a receipt or the like using the printer 20.

Thereafter, when the close key is pressed, issuing of a receipt is controlled. Further, the program is set to clear the contents of the sales quantity area 32a of the bulk sale product table 32 and the contents of each totalizer 33, 34 to "0".

In this embodiment having such a configuration, the product name and unit price are preset in the product file 31 in correspondence with the product code of each product handled at the store. Furthermore, for the products designated for bulk sale, the M&M flag in the flag area 31a is set to "1", and any bulk sale is established in the bulk sale product table 32 corresponding to the product code of each bulk sale designated product. The number of items and the transaction amount are preset.

[0029] When the keyboard 16 or the barcode scanner 24 is operated to input the product code of the product purchased by the customer, the product name and unit price corresponding to the input product code are read from the product file 31. . Then, the unit price is accumulated in the contents of the total sales amount area 31b corresponding to the input product code in the product file 31, and the contents of the total sales quantity area 31c corresponding to the input product code are updated by "+1". Further, the above unit price is added to the contents of the sales amount totalizer 33. Note that the sales amount totalizer 33 is cleared to "0" before the first product registration for one customer is started.

Therefore, in the total sales amount area 31b of the product file 31, the total sales amount of the products registered for sale is accumulated for each product, and in the total sales number area 31c, the total number of products sold is counted for each product. On the other hand, sales amount totalizer 33
stores the total amount of products purchased by one customer.

Further, when the product code of the product purchased by the customer is input from the keyboard 16 or the barcode scanner 24, the M&M flag corresponding to the input product code in the product file 31 is checked. Here, if the same flag is set to "1", it is determined that the product is registered for bulk sale, and the contents of the sales quantity area 32a corresponding to the input product code in the bulk sale product table 32 are set to "1". +1” will be updated. Note that the sales quantity area 32a is cleared to "0" before the first product registration for one customer is started. Therefore, in the sales quantity area 32a of the bulk sale product table 32, the number of sold items of bulk sale specified products purchased by one customer is counted for each product.

[0032] When this sales quantity count value becomes an integral multiple of the number of sold items for the corresponding bulk sale specified product, it is determined that the bulk sale for the corresponding bulk sale specified product has been completed. Then, a discount amount is automatically calculated by subtracting the established amount from the amount when purchasing the applicable bulk sale designated products at the normal unit price for the number of units that can be purchased, and the total sales amount area 31b corresponding to the input product code in the product file 31 is calculated. The discount amount is subtracted from the contents of , and the discount amount is added to the contents of the discount amount totalizer 34 . Further, the contents of the M&M formation count area 31d corresponding to the input product code in the product file 31 are updated by "+1". Note that the discount amount totalizer 34 is cleared to "0" before the first product registration for one customer is started.

[0033] Therefore, in the M&M number of times area 31d of the product file 31, the number of times a bulk sale of products designated for bulk sale is completed is counted for each product. On the other hand, the discount amount totalizer 34 stores the total discount amount due to bulk sales for one customer.

[0034] According to this embodiment, the total number of sold items and the number of times that bulk sales are completed for products designated for bulk sale are displayed in the total sales quantity area 31c and the number of M&M sales completed areas 31d of the product file 31, respectively, for each product. It is aggregated and managed. Therefore, by checking the contents of the product file 31 through "inspection" or "settlement" operations, necessary data such as the sales ratio of the number of products sold in bulk to the total number of products sold in bulk can be easily obtained. can.

In the above embodiment, the product file 31 is provided in a POS terminal, but it is provided in a higher-level controller connected to the POS terminal via a transmission path, and registered in each POS terminal in this higher-level controller. It is also possible to compile and manage the total number of sold products designated for bulk sale, the number of times the bulk sale was completed, and the like.

[0036]

Effects of the Invention As detailed above, according to the present invention, it is possible to manage the total number of products sold in bulk as well as the number of times bulk sales have been completed for each product, and the number of products sold in bulk relative to the total number of products sold can be managed. It is possible to provide a product sales data processing device that can easily acquire necessary data such as sales ratios.
