Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a transaction processing device with a so-called PLU function.

[Prior Art] Some transaction processing devices such as ECRs (electronic cash registers) have a so-called PLU function. P
The LU (Price Look Up) function is a product code that identifies each product and the unit price data of that product is stored in the PLU file in advance. The operator simply inputs the product code, and the product code from the PLU file is stored. Is a function for reading out and registering unit price data corresponding to.

Conventionally, the unit price of a specific product may be temporarily changed by a leaflet, a special sale, a time service, etc. In that case, the unit price is changed using the following method.

In the first method, if the unit price change period is reached, PL
This is a method of directly changing the unit price of the target product in the U file and returning the changed unit price in the PLU file to the original unit price if it is outside the target period.

The second method is a method of changing the unit price by subjecting the unit price registered in the PLU file for the target product to discounting or discounting each time.

[Problems to be Solved by the Invention] However, in the first method of directly changing the unit price of the PLU file, since the PLU file has a large capacity, the unit price changing work becomes complicated, and data addition, deletion, and change are performed. There was a problem that such work took time.

In particular, when the time for which the unit price is changed is determined, there is a problem that the unit price must be changed and corrected each time.

Also, in the second method of discounting or discounting each time from the unit price registered in the PLU file, the processing becomes complicated when the discount rate or the discount amount differs for each product,
There was a problem that many operation mistakes occurred.

Therefore, an object of the present invention is to provide a transaction processing device that can easily perform a unit price change process when temporarily changing the unit price of a product.

[Means for Solving Problems] A transaction processing device according to the present invention includes a PLU file storing a product code and unit price data of each product, a product code of a product whose unit price is changed, unit price change data, and a time. A temporary file for storing the product code, an input means for inputting the product code, a time measuring means for measuring the current time, a PLU file searching means for reading the unit price data from the PLU file, and a temporary for reading the unit price change data from the temporary file. A file search means and a unit price data changing means for changing the unit price data based on the unit price change data are provided.

When the product code is input by the input means, the PLU file search means is a PLU file based on the product code.
The file is searched and the unit price data corresponding to the product code is read. The temporary file search means is
When the product code is input by the input means, the temporary file is searched based on the product code, the product code is found, and the time counted by the time measuring means is recorded in the temporary file. Only when it is within the target time, the unit price change data corresponding to the product code is read. The unit price data changing unit changes the unit price data read by the PLU file searching unit based on the unit price change data when the unit price changing data is read by the temporary file searching unit.

[Operation] In the transaction processing device according to the present invention, when the product code of a product is input by the input means, if the product is a product for which the unit price is changed, the product is selected from the PLU file by the PLU file search means. The unit price data corresponding to the code is read, and the unit price change data corresponding to the product code is read from the temporary file by the temporary file search means. At this time, if the clocked time is outside the unit price change target time stored in the temporary file, the unit price change data is not read. Then, based on the unit price change data, the unit price data is changed by the unit price data changing unit.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a schematic block diagram showing the electrical configuration of the ECR to which the present invention is applied.

As shown in FIG. 2, a CPU 1, a keyboard 2, a scanner 3, a display 4, a printer 5, a clock 6, a P-ROM 7, and an internal memory 8 are connected to an external memory interface 9 through an external memory interface 9. 10 are connected.

The keyboard 2 is for inputting a product code, a price of a product, and various instructions, and the scanner 3
Is for reading the product code from the bar code attached to the product. Further, the display unit 4 displays the amount of money or the name of the product input from the keyboard 2, or the total amount of money calculated by the CPU 1. Then, the printer 5 prints the product name and price of the product and the total price of the purchased product and issues it as a receipt.

The P-ROM 7 stores the operation program of the CPU 1 based on the flowchart shown in FIG. 1 described later. The internal memory 8 is used as a work memory that temporarily stores data and the like input from the keyboard 2 and the scanner 3. The external memory 10 is also used to store the PLU file and the temporary price file.

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

As shown in the figure, the keyboard 2 includes 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 are provided.

The registration mode setting switch 21 is for setting the ECR in a registration mode for performing merchandise registration and payment processing, and the ten-key 22 is for inputting numerical data such as a merchandise code and the amount of merchandise. The clear key 23 is for clearing the numerical data and the like input from the ten keys 22. The product key 24 is operated so as to input a product code, and the subtotal key 25 is operated when totaling the amount data inputted from the ten keys 22. The deposit / cash total key 26 is operated when inputting the amount of money received from the customer and calculating the change.

FIG. 4 is a diagram showing configurations of the internal memory 8 and the external memory 10 shown in FIG.

The internal memory 8 is composed of an input data memory 81, a registration data memory 82, a product code memory 83, a current time memory 84, a total purchase memory 85, and a selling price change memory 86.

The input data memory 81 stores the function key code and the input numeral data. The function key code is, for example, "0" when the product key 24 is operated.
It becomes "1" and becomes "02" when the scanner 3 is used. The input number data at this time is a product code. The function key code becomes "10" when the subtotal key 25 is operated and becomes "11" when the deposit / cash total key 26 is operated.

The product code memory 83 stores the product code input from the keyboard 2 or the scanner 3. In the registration data memory 82, based on the product code stored in the product code memory 83, the corresponding product code, product name, and selling price are transferred and stored from the PLU file of the external memory 10. The present time is input from the clock 6 and stored in the present time memory 84. The total purchase amount memory 85 stores the total amount of products purchased by the customer. Selling price change memory 86
Based on the product code stored in the product code memory 83, the corresponding product code, start time, end time, change classification, and change data are transferred and stored from the temporary price file in the external memory 10. .

The external memory 10 stores a PLU file 11 and a temporary price file 12. In the PLU file 11, product codes, product names, selling prices, and sales amounts are registered for each product. Further, the temporary price file 12 stores a product code, a start time, an end time, a change classification, and change data for each product for which the selling price is to be changed. Here, the start time and the end time respectively indicate the start and end of the time zone for which the selling price is changed. When the selling price is changed, the change classification is set to "1", and the change data at this time shows the selling price after the change. Further, the change category is set to “2” at the time of discount, and the change data at this time indicates the discount amount.

Next, referring to the flow chart of FIG.
The operation of ECR will be described.

First, at the start of processing, a predetermined work memory, that is, all internal memories 8 are initialized (step S
1). Next, the product code is input from the keyboard 2 or the scanner 3 and stored in the input data memory 81 as input unit data. Normally, the product code is obtained by scanning the bar code attached to each product with the scanner 3, but when the scanner 3 is defective, the product code is obtained using the ten-key pad 22 of the keyboard 2 as shown in FIG. After the input, the product key 24 is pressed (step S2). When the product key 24 is pressed or the product code is input by the scanner 3, the input replacement data of the input data memory 81 is transferred to the product code memory 83 (steps S3, S4). And the product code memory 83
PLU file 11 in external memory 10 based on the product code
Is searched (step S5). When the PLU file 11 has a product code that matches the product code in the product code memory 83, the corresponding product code and the corresponding product name and selling price are transferred to the registered data memory 82 (step
S6, S7). If there is no product code in the PLU file 11 that matches the product code in the product code memory 83, the product is unhandled and the process proceeds to error processing (step S6). Next, based on the product code in the product code memory 83, the external memory 10
The temporary price file 12 is searched to determine whether or not a product code matching the product code in the product code memory 83 exists in the temporary price file 12 (step S8). If the product code that matches the product code in the product code memory 83 is in the temporary price file 12, the applicable product code and the corresponding start time, end time, change classification, and change data are subject to sale price change. Transfer to the selling price change memory 86 (steps S9, S10).

Next, the current time is read from the clock 6 and the time is stored in the current time memory 84 (step S11). Then, it is determined whether the time of the current time memory 84 is between the start time and the end time of the selling price change memory 86, that is, the selling price change target time (step S12). If it is within the selling price change target time, it is judged whether the change classification of the selling price change memory 86 is "1" or "0" (step).
S13, S14). If the change classification is "1", it means that the selling price has been changed, and the changing data in the selling price changing memory 86 indicates the selling price after the changing. Therefore, the selling price in the registered data memory 82 is replaced with the selling price (step S15). If the change category is "0", the discount process is performed. Since the change data in the selling price change memory 86 indicates the discount amount, the discount amount is subtracted from the selling price in the registered data memory 82 (step S16).

In this way, the selling price of the registration data memory 82 becomes the selling price after the change, so that the product name and the selling price of the registration data memory 82 are displayed on the display 4 and printed by the printer 5 (steps S17, S18).

Further, the selling price of the registered data memory 82 is added to the total purchase amount of the total purchase memory 85 (step S19), and the PLU file is added.
The selling price of the registered data memory 82 is added to the sales amount of the corresponding 11 products (step S20).

In step S9, if the product code that matches the product code in the product code memory 83 does not exist in the temporary price file 12, the product is not the product subject to the selling price change, so the selling price in the registered data memory 82 should be changed. Not a step
Proceed to S17. Further, in step S13, if the time of the current time memory 84 is not between the start time and the end time of the selling price change memory 86, it is outside the selling price change target time, so without changing the selling price of the registered data memory 82, Proceed to step S17.

In this way, it is possible to determine whether or not the product is a product whose selling price is changed by simply inputting the product code of the product with the keyboard 2 or the scanner 3.
It is determined whether or not the current time is included in the time zone for which the selling price is changed, and the selling price of the product is automatically changed.

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

[Effect of the Invention] As described above, according to the present invention, the product code of each product and the normal unit price data are stored in the PLU file, and only for the product for which the unit price is changed, the product code, the unit price change data and the target are changed. Time is stored in a temporary file, and the unit price of the target product is automatically changed based on the unit price change data of the temporary file, so there is no need to change the large capacity PLU file when changing the unit price, and the work is simple It will be realized and operation mistakes will be eliminated.
Further, since the temporary file manages only the products for which the unit price is changed, it is possible to easily add, modify, delete, etc. in a short time. Furthermore, the unit price change is automatically performed only within the time stored in the temporary file, and the unit price stored in the PLU file is used outside that time, and it is not necessary to change or repair the PLU file. Therefore, various unit prices can be changed only by changing the temporary file, and it becomes easy to support various service forms.
