Abstract

PROBLEM TO BE SOLVED: To prevent an article from being sold, without noticing that the article is sold at less than a cost by previously storing the cost of each article and generating an alarm when a selling price is less than the cost. SOLUTION: In an article file 20 provided to a file processor 6 connected through a communication line 5, the cost of an article is previously set and stored together with the unit price, etc., corresponding to the article code of the article. When an operator inputs a deduction amount and a reduction rate on a keyboard 8 for the discount sale of a customer-purchased article and inputs the article code of the customer-purchased article through a scanner 14 or the keyboard 8, article data, such as the unit price, cost, etc., of the customer-purchased article are acquired from the article file 20 and the deduction amount is subtracted from the unit price to calculate a selling price. Then it is judged whether or not the selling price is less than the cost of the article, and when the selling price is less than the cost, a buzzer sounds and the deduction below the cost is displayed at a display unit 10 at the same time.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product sales registration data processing device such as an electronic cash register or a POS (point of sale information management) terminal having a single product registration function.

[0002]

2. Description of the Related Art A conventional product sales registration data processing device having a single product registration function is a data file in which product data such as a unit price of a corresponding product is stored in advance corresponding to each product code set for each product. Was provided in a built-in storage device or a storage device of an external device connected via a communication means. Then, when the product code of the sale product is input through the product code input means such as a scanner or a keyboard,
Read the product data such as the unit price corresponding to the input product code from the above data file, multiply the unit price in this product data by the number of sales points to calculate the sales price, and accumulate the sales data of this sales price and the number of sales items. It was supposed to process sales registration in a file.

Further, this type of merchandise sales registration data processing device has a discount information input means for inputting a discount amount or a discount rate so as to deal with a discount on a product. Then, when the product code of the sold product is input through the product code input device and the discount information of the sold product is input through the discount information input device, the unit price of the corresponding product read from the data file is calculated. If the selling price is obtained by subtraction operation, the sales data of the selling price and the number of sales points is registered in the cumulative sales file.

[0004]

However, in the conventional product sales registration data processing device of this type, the discount price or the discount rate inputted by the operator is too large, and the sales price of the sales product is the cost of the product. Even if it falls below, sales registration processing of product sales data was performed without any warning being issued. Therefore, it is impossible to prevent the inconvenience of selling the product without noticing that the selling price is lower than the cost.

The present invention has been made under such circumstances, and an object thereof is to prevent inconvenience of selling a product without noticing that the selling price is lower than the cost. The present invention intends to provide a merchandise sales registration data processing device that can be used.

[0006]

The present invention has a data file in which product data such as a unit price of a corresponding product is stored in advance corresponding to each product code set for each product, and the data file When the product code of the sales product is input, the product data corresponding to the input product code is read from the data file, and the product sales data such as the sales price and the number of sales of the sales product is acquired based on the product data, In a product sales registration data processing device that performs sales registration processing of this product sales data, when the cost of each product is stored in advance and the sales price of the sales product whose product code is input by the input means is acquired, this sales price and the product The price is compared with the price of and the warning is issued when the selling price falls below the cost.

[0007] As one of the means, there are a cost storing means for storing the cost of each product in advance, a cost stored by the cost storing means of the sold product whose product code is inputted by the input means, and a selling price of this sold product. An amount comparing means for comparing and a warning means for issuing a warning when the selling price is lower than the cost as a result of the comparison by the amount comparing means.

In this case, when the selling price as a result of the comparison by the comparing means is lower than the cost, there is provided a selecting means for selecting whether or not to execute the sales registration processing of the merchandise sales data including the selling price. When the execution is selected, it is preferable that the sales registration processing of the commodity sales data including the sales price is executed.

Further, only when the sales price after the discount processing of the sales product whose product code is input by the input means is acquired, the sales price is compared with the cost of the product, and when the sales price is lower than the cost. A warning may be issued.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, a file processor in which a data file in which product data such as a unit price of a corresponding product is stored in advance corresponding to each product code set for each product is connected via a communication line. The case of applying to a POS terminal prepared for is explained.

FIG. 1 is a block diagram showing the structure of the main part of such a POS terminal.
A CPU (Central Processing Unit) 1 is mounted as a control unit main body. Further, a ROM (read only memory) 2 in which fixed data such as a program for the CPU 1 to control each unit is stored in advance, a cumulative sales file for sales registration processing of sales data of each product, and product sales for one transaction RAM (random access memory) 3 forming various memory areas such as transaction files for accumulating and storing data, clock circuit 4 for clocking date and time, eg H

A communication interface 7 for transmitting / receiving data to / from a file processor 6 connected via a communication line 5 such as a line is provided.

Further, as shown in FIG. 3, the POS terminal further includes a numeric key 31, a clear key 32, a PLU (price look up) key 33, and a deposit / cash total key 3.
4, a keyboard controller 9 for controlling the keyboard 8 provided with various keys such as an execution key 35, a discount key 36, a discount key 37, an amount key 38, and a multiplication key 39, the name and sale price of the registered product for sale, A display controller 11 for controlling a display 10 for displaying and outputting the total amount and change amount of the customer's purchased products, and a printer 1 for printing transaction data on receipt paper and journal paper and issuing a receipt.
2, a printer controller 13 for controlling the printer 2, a scanner controller 15 for optically scanning a barcode or the like, and a scanner controller 15 for controlling the input / output devices, a drawer opening device 16 for automatically opening a drawer (not shown), and a buzzer (not shown). Buzzer drive circuit 17 for ringing (shown in the figure) is equipped with I / O ports 18 for sending drive signals.

Then, the CPU 1, the ROM 2 and the RA 2
M3, clock circuit 4, communication interface 7, input / output device controllers 9, 11, 13, 15 and I / O port 18 are connected to bus lines 19 such as an address bus and a data bus.
To establish a control circuit for the POS terminal.

The file processor 6 is provided with a single item file 20 as a data file in which product data such as a unit price of the corresponding product is stored in advance corresponding to each product code set for each product. FIG. 2 shows an example of the structure of one product data stored in the single product file 20. That is, in the single item file 20, a single item code (7 bytes) 21, a link department code (2 bytes) 22, a name (14 bytes) 23, a unit price (3 bytes) 24, and a cost (3
Bytes 25, status (1 byte) 26, sales amount (5 bytes) 27, sales points (4 bytes) 28, latest sales date (2 bytes) 29 are stored in advance for all products. ing. Here, the single item file 20 constitutes a cost storage means.

In such a POS terminal, the CPU 1 controls each unit according to the processing procedure shown in the flowchart of FIG.
It constitutes a program in OM2. When starting this single item registration work, the RAM 3 is formed with a discount information memory 41, a selling price memory 42, and a flag memory 43 of the discount flag F, as shown in FIG.

First, the CPU 1 determines in ST (step) 1 whether or not the discount information has been input for the customer-purchased product. By the way, in this POS terminal, as a means for inputting discount information, after inputting a discount key 36 to declare a discount amount, a method of inputting a discount amount by the numerical key 31 and a discount It is assumed that there are two methods of inputting the discount rate by using the numeric key 31 after the key 37 is declared to input the discount rate. And
If the discount information is input by either method, the discount flag F in the flag memory 43 is set to "1" and the input discount information (the discount amount or the discount rate and the discount information The status (identifying the type) is stored in the discount information memory 41.

Next, the CPU 1 determines in ST2 whether or not the single-item code of the customer-purchased commodity has been input. By the way, in this POS terminal, as a means for inputting a single product code, for example, a method of reading and inputting a single product code that has been bar-coded by the scanner 14 and a method of inputting a single product code with the numeric keypad 31 and then inputting the PLU key 33 are entered. There are two ways to do it. When the single product code is input by any of the methods, the communication interface 7 is controlled to transmit an input product code inquiry command to the file processor 6, and the file processor 6
The product data that the input single product code and the single product code 21 match from the single product file 20 provided in
2, name 23, unit price 24, cost 25, status 26)
To get.

Next, the CPU 1 checks the state of the discount flag F in the flag memory 43 in ST3. Here, when the discount flag F is reset to "0", the discount information has not been input for the customer purchase product, and therefore the unit price 24 in the product data acquired from the single product file 20 is set. The selling price memory 42 as the selling price of the customer purchase product.
To be stored.

When the discount flag F is set to "1" in ST3, the discount information has been input for the customer-purchased product, so the discount flag F is set to "0".
After that, whether the discount information in the discount information memory 41 is the discount amount or the discount rate is determined by the status in the discount information. When the discount is applied, the discount information memory 4 is calculated from the unit price 24 in the product data acquired from the single-item file 20.
The discount price in 1 is reduced to obtain the selling price, and the selling price memory 4
2 is stored. On the other hand, at the discount rate, the discount rate is calculated by multiplying the unit price 24 in the product data acquired from the single item file 20 by the discount rate in the discount information memory 41.
Then, the discount amount is subtracted from the unit price 24 to obtain the selling price, which is stored in the selling price memory 42.

Next, in step ST4, the CPU 1 compares the selling price in the selling price memory 42 with the cost 25 in the product data acquired from the single item file 20 (amount comparison means). If the selling price is 225 or more,
Execute single item sales registration processing. That is, the selling price memory 4
The sales price is calculated by multiplying the sales price in 2 by the number of sales points (the multiplier if the multiplier key 31 and the multiplication key 39 have been entered just before entering the individual product code, or "1" otherwise). Then, the sales data of the sales amount and the sales points is registered in the sales cumulative file in the RAM 3. In addition, transaction data including the single item code 21, the sales amount and the number of sales points is created and stored in the transaction file of the RAM 3. Furthermore, the name 23 and the unit price 24 in the product data acquired from the single product file 20
Also, the registered commodity specification data such as the number of sales and the sales amount are created and displayed on the display 10. When the above-described single-item sales registration processing is completed, the single-item registration operation for this customer purchase product is completed.

When the selling price is lower than the cost 25 in ST4, a drive signal is sent to the buzzer drive circuit 17 to make the buzzer sound, and a warning message is sent to the operator to inform the operator that the cost is below the display 10 ( For example, "Cost breaks. Can I register as it is?"
Etc.) is displayed to warn of a price break (warning means). Here, the process waits for any of the execution key 35 and the clear key 32 to be input. Then, the execution key 35
If is input, the execution of the single item sales registration process for the product whose cost has been broken down is selected, and thus the single item sales registration process described above is executed and the single item registration operation for this customer purchase product is completed.

On the other hand, if the clear key 32 is entered, the single item sales registration process invalidation of the product whose cost has been broken is selected. Therefore, the single item sales registration process is not executed and the single item registration of this customer purchase product is performed. End the work.

Further, when the CPU 1 detects the input of the deposit / cash total key 34 after the completion of the customer purchase product registration work, it is declared that the registration of all the products purchased by the customer is completed. Execute closing operations. That is, the total amount of money is calculated based on the product sales data stored in the transaction file and displayed on the display 10. Then
When the deposit amount is entered with the numeric key 31 and the deposit / cash total key 34, the total amount is subtracted from the deposit amount to calculate the change amount, which is displayed on the display 10 and driven by the drawer opening device 16. Send a signal to open the drawer. Also, receipt print data is created based on the transaction file data and registration closing data such as total amount, deposit amount and change amount, and is sent to the printer 12 to perform receipt printing and journal printing, and issue a receipt. Thereafter, when the communication interface 7 is controlled and the data of the transaction file is transmitted to the file processor 6, the transaction file is cleared and the registration closing operation is completed.

The POS having the above-described structure according to the present embodiment
In the terminal, in the single item file 20 provided in the file processor 6 connected via the communication line 5, the unit price of the item and the cost are set and stored in advance in correspondence with the item code of each item.

In this state, the operator of the POS terminal inputs the discount amount or the discount rate from the keyboard 8 in order to carry out the discount sale of the customer-purchased merchandise, and then inputs the single item code of the customer-purchased merchandise from the scanner 14 or the keyboard 8. Then, product data such as the unit price and cost of the customer-purchased product is acquired from the single-unit file 20, and the discount price is reduced from the unit price to calculate the selling price. Then, it is determined whether this selling price is lower than the cost of the corresponding product. If it does not fall below, the sales data of this customer-purchased product is unconditionally registered for sales.

On the other hand, when the selling price is lower than the cost, the buzzer sounds, and at the same time, a warning message is displayed on the display 10 to inform the operator that the price is low, and a warning is issued. Therefore, when the product is sold at a discount regardless of the price break, the operator depresses the execution key 35. Then, the sales data of the customer-purchased product is registered for sales. On the other hand, if the product is not sold at a discount due to a price break, the operator presses the clear key 32. Then, the sales registration processing of the sales data of the customer purchase product is not performed, and the discount sale becomes invalid.

As described above, according to the POS terminal of the present embodiment, when the cost of each product is stored in advance and the selling price of the selling product for which the single item code is input by the input means is acquired, the selling price and We compared the cost of goods and issued a warning when the selling price fell below the cost, so even if the discount price or discount rate is too large and the selling price is below the cost, the operator can It is possible to surely eliminate the inconvenience of registering a customer-purchased product for sale without noticing it. In addition, when the selling price falls below the cost, a warning is issued, so for example, fraudulent fraud such as an operator who makes an expensive discount to an acquaintance's customer can not be done, and the loss of the store can be reduced. Also plays.

Further, when the selling price is lower than the cost, there is provided selecting means (execution key 35, clear key 32) for selecting whether or not to execute the sales registration processing of the merchandise sales data including this selling price, and this selecting means is provided. When it is selected to execute by, the sales registration process of the product sales data including this sales price is configured to be executed. Therefore, even if the sales price falls below the cost, it can be easily sold or not sold. It can be selected by operation and is highly practical.

Further, in the POS terminal of the present embodiment, the selling price and the cost are compared not only for the product for which the unit price set in the individual product file 20 is sold by discount but also for the product which is not sold for discount. Checking for cost breaks. Therefore, even if the unit price is set lower than the cost by mistake when setting the unit price in the single unit file 20, it is possible to prevent the product from being sold at the unit price when the cost is broken, and the store price may be set incorrectly. It also has the effect of preventing people from suffering losses.

However, in some commercial transactions, it may be convenient to sell even if the unit price is lower than the cost. In this case, the unit price lower than the cost is set in the unit file 20. Become. Then, in the above-mentioned embodiment, a warning is always issued at the time of sales registration for a product for which a unit price lower than the cost is set in the single-item file 20.
This causes a significant decrease in processing efficiency.

Therefore, as shown in the flowchart of FIG. 6, when the discount flag F is reset to "0" in ST3 in the processing of the single item registration work, that is, for the product not to be discounted for sale, the process of ST4 is executed. It is also possible to eliminate the above-mentioned decrease in processing efficiency by changing the processing to perform the single-item sales registration processing unconditionally without performing the comparison processing between the selling price and the unit price.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the cost is stored for all the products set in the single item file 20, but the cost is stored only for the product prohibited to be sold, and the selling price and the cost are stored only when the product is registered for sale. It may be possible to check whether or not there is a cost break by performing a comparison process with. In this case, for example, a flag for identifying whether or not to perform the comparison process is provided in the status in the single-item file 20 to easily cope with the situation. By doing so, the processing efficiency can be improved because the comparison processing of the selling price and the cost is not performed at the time of the sales registration for the product for which the cost break check is unnecessary.

Further, in the above embodiment, both the warning by the buzzer and the warning by the message display are shown as the warning means, but only one of them may be provided. Further, the operator may be warned by another method.
In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention, such as applying the present invention to a single electronic cash register including a single file in a storage device inside the device.

[0034]

As described in detail above, according to the present invention,
Since the selling price of the selling product is compared with the cost of the product, a warning is issued when the selling price falls below the cost.
It is possible to provide a product sale registration data processing device capable of preventing the inconvenience of selling a product without noticing that the selling price is lower than the cost.

Further, as a result of comparing the selling price of the sold product with the cost of the product, when the selling price is lower than the cost, it is selected whether or not to execute the sales registration process of the product sales data including the selling price. Since the selecting means is provided, it is possible to select whether to sell or not to sell even if the cost is broken by a simple operation, and it is possible to improve the practicality.

Further, only when the selling price after the discount processing of the selling product is acquired, the selling price is compared with the cost of the product, and a warning is issued when the selling price is lower than the cost. A warning is not issued for products whose unit price is set lower than the cost in advance, and there is an advantage that the processing efficiency can be improved as compared with the case where the selling prices of all the products are compared with the cost.
