Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a merchandise sales registration data processing system called a POS (Point Of Sales) system.
[0002]
[Prior art]
For example, in general supermarkets that sell not only food and daily goods, but also clothing, home appliances, stationery, toys, etc., generally, POS terminals installed at each sales floor and file processors installed at store management offices, etc. And a POS system that is connected by a communication line.
[0003]
In this POS system, the file processor sets and stores single product data such as a link code, a product name, and a unit price linked to the single product code corresponding to the single product code attached to each product in advance. Set up and store a single item file that aggregates and stores the sales data of sales points and sales amounts by code, and link data such as link names corresponding to the link codes, and totals sales data of sales points and sales amounts by link code It functions as a file management device that manages the link files to be stored.
[0004]
On the other hand, each POS terminal is provided with a scanner, a keyboard, and the like for inputting a single item code, the number of sales points, etc. as product registration means for registering sales of products. When the product registration is performed by the product registration means, single product data corresponding to the single product code of the registered product is obtained from the single product file, and the sales price is calculated from the unit price and the sales points in the single product data. . Then, sales transaction data is created from the single product code of the registered product, the link code linked to it, the number of sales points, and the sales amount, and the sales transaction data is transmitted to the file processor via the communication line.
[0005]
The file processor that has received the sales transaction data includes the sales points and sales amounts in the data, the sales points and sales amounts corresponding to the single item codes in the data in the single item file, and the data in the link file. Addition processing is added to the number of sales points and the sales amount corresponding to the link code. As a result, the sales of each product in the entire store are classified and totaled for each single item code and each link code.
[0006]
[Problems to be solved by the invention]
However, in the conventional POS system, the products with the same single item code are aggregated as the sales of the same link code regardless of the sales POS terminal at any sales floor. For this reason, for example, if there are products that are sold at the same unit price across multiple sales floors, and you want to aggregate the sales of those products by sales floor, you must set the single item code for this product differently for each sales floor. In other words, there is a problem that the management of the product becomes complicated.
[0007]
Therefore, the present invention can process the sales of one product as sales of different link codes depending on the product sales registration device that has registered the product for sale without complicating product management, and can improve the practicality. It is intended to provide a data processing system.
[0008]
[Means for Solving the Problems]
The invention according to claim 1 of the present application is a single item setting file that stores in advance a link code linked to a single item code corresponding to each single item code, a single item sales totaling file that summarizes sales data by single item code, and a link code Separately, product sales registration data obtained by connecting a file management device that manages a link sales summary file that aggregates sales data, and a plurality of product sales registration devices that have product registration means for performing product sales registration In the processing system, change data storage means for storing link code change data in each product sales registration device, and when the product registration is performed by the product registration means, a link code linked to the single product code of the product is set individually. The code reading means to read from the file and the link code read by this code reading means Sales target data is created using a link code read from a single item setting file when it is determined that it is not subject to change, and when it is judged that it is subject to change. Sales data creation means for creating sales data with the link code changed by the changed data stored in the data storage means, and sales data transfer for transferring the sales data created by the sales data creation means to the file management device via the communication line Means. Further, the file management apparatus updates the single-item sales total file and the link sales total file based on the sales data collected from each merchandise sales registration apparatus via the communication line.
By taking such means, when the product registration is performed by the product registration unit in the product sales registration device, the link code linked to the single product code of the product is read from the single product setting file. Then, it is determined whether or not this link code is a change target. Here, if it is not a change target, sales data is created with a link code that is linked to the single item code of the product set in the single item setting file, transferred to the file management device via the communication line, and single item The sales summary file and the link sales summary file are updated. On the other hand, when it is a change target, the link code linked to the single item code of the product is changed with the change data stored in the change data storage means. Then, sales data is created with the changed link code, transferred to the file management device via the communication line, and the single item sales total file and the link sales total file are updated.
Therefore, even if a product with the same single product code is registered for sale with a product sales registration device for which the change data of the link code linked to the single product code of the product is set, it is registered with a product sales registration device that is not set In the case of being done, data is aggregated as sales of another link code. In addition, even if the change data is different between the merchandise sales registration apparatuses in which the change data is set, the data is aggregated as sales of another link code.
[0009]
According to the second aspect of the present invention, in the single item setting file, the link code change number is stored in advance together with the link code linked to the single item code corresponding to the single item code unique to each item. Then, the change data storage means possessed by each product sales registration device is a means for selectively setting and storing the changed link code corresponding to the change number of the link code, and the code reading means is used to sell the product by the product registration means. When registration is performed, the link code linked to the single product code of the product and the change number are read from the single item setting file, and the change target determining means is the change data storage means with the change number read by the code reading means. This is a means to search and check whether the changed link code is set, and when the sales data creation means determines that the changed link code is not set by the change target judging means, the link code read from the single item setting file After creating the sales data and determining that the new link code has been set, And means for creating a sales data in Kukodo, sales data transfer means, in which the means for transferring the file management apparatus via a communication line sales data created by the sales data generation means.
By taking such means, when the product sales registration is performed by the product registration means in the product sales registration device, the link code and the change number linked to the single product code of the product are read from the single product setting file. . Then, it is determined whether or not a post-change link code is set corresponding to this change number. Here, if the changed link code is not set, sales data is created with the link code linked to the single item code of the product set in the single item setting file, and the file management device via the communication line And the single item sales summary file and the link sales summary file are updated. On the other hand, if a post-change link code is set, sales data is created with the post-change link code, transferred to the file management device via the communication line, and a single product sales summary file and link sales summary The file is updated.
Therefore, even if a product with the same single product code is registered for sale with a product sales registration device that has a changed link code for the link code change number linked to the single product code of that product, it is not set. When sales are registered by the product sales registration device, data is aggregated as sales of another link code. In addition, even if the post-change link code is different between the product sales registration apparatuses in which the post-change link code is set, the data is aggregated as sales of another link code.
[0010]
The invention according to claim 3 of the present application uses the change data storage means included in each product sales registration device as means for selectively setting and storing the changed link code corresponding to the single item code of each product, and the code reading means, When a product is registered for sale by the product registration means, the link code linked to the single item code of the product is read from the single item setting file, and the change target judgment means is the single item code of the product registered for sale by the product registration means. When the change data storage means is searched to check whether the post-change link code is set, and the sales data creation means determines that the post-change link code is not set by the change target determination means, the single item setting file When sales data is created with the link code read from, and it is determined that the changed link code is set And means for creating a sales data in the post-change link code, the sales data transfer means, in which the means for transferring the file management apparatus via a communication line sales data created by the sales data generation means.
By taking such means, when the product registration is performed by the product registration unit in the product sales registration device, the link code linked to the single product code of the product is read from the single product setting file. Further, it is determined whether or not the changed link code is set corresponding to the single product code of the product. Here, if the changed link code is not set, sales data is created with the link code read from the single item setting file, transferred to the file management device via the communication line, and the single item sales summary file and The link sales summary file is updated. On the other hand, if a post-change link code is set, sales data is created with the post-change link code, transferred to the file management device via the communication line, and a single product sales summary file and link sales summary The file is updated.
Therefore, even if a product with the same single product code is registered for sale with a product sales registration device that has a changed link code for the single product code of the product, it is registered with a product sales registration device that is not set. In this case, data is aggregated as sales of another link code. In addition, even if the post-change link code is different between the product sales registration apparatuses in which the post-change link code is set, the data is aggregated as sales of another link code.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, a first embodiment corresponding to the first and second aspects of the present invention will be described with reference to FIGS. 1 to 5 and FIG.
[0012]
FIG. 1 shows an outline of a merchandise sales registration data processing apparatus, a so-called POS system, according to the first embodiment. This POS system includes one file processor 1 functioning as a file management apparatus, and a merchandise sales registration apparatus. N (N ≧ 2) POS terminals 2A, 2B,..., 2N functioning as
[0013]
The file processor 1 is a computer device having a built-in large-capacity storage medium such as a hard disk, and the large-capacity storage medium has a single-unit code corresponding to a single-unit code unique to each product as shown in FIG. As shown in FIG. 4, a single item setting file that stores single item data such as link codes, single item names, unit prices, etc. that are linked in advance, and a single item sales summary file that functions as a single item sales summary file that totals point and monetary sales data for each item code. In addition, it is possible to rewrite the link setting file that stores link data such as link names in advance corresponding to each link code and the link file 5 that functions as a link sales total file that counts sales data of points and amounts for each link code. It is managed by holding it in memory. The file processor 1 is connected online with a store computer 6 that performs maintenance analysis of the single file 4 and the link file 5 and collects and processes the data collected in the files 4 and 5 to analyze sales. .
[0014]
The POS terminals 2A to 2N have the same configuration, and as shown in FIG. 2, a CPU (Central Processing Unit) 21 is mounted as a control unit main body. Further, a ROM (Read Only Memory) 22 in which a program executed by the CPU 21 is stored in advance, a RAM (Random Access Memory) 23 in which various data are read and written by the CPU 21, and data transmission performed through the communication line 3 are controlled. Communication interface 24, I / O port 25 for inputting signals from sensors, switches, etc. and outputting drive signals for drawers, scanner controller 26C for fetching data corresponding to the barcode read by scanner 26, keyboard 27 controls the drive of the keyboard controller 27D for fetching data corresponding to the input key 27, the display controller 28C for controlling the drive of the display 28 and displaying the product name, price, etc. of the product registered for sale, and the drive of the printer 29 Printer controller for printing receipts It is equipped with a La 29C and the like.
The CPU 21, ROM 22, RAM 23, communication interface 24, I / O port 25, and controllers 26C, 27C, 28C, 29C of each input / output device are connected by a bus line BL such as an address bus or a data bus. The control circuit is configured.
[0015]
The scanner 26 optically reads a barcode (single product code) attached to each product. The keyboard 27 is a dedicated keyboard for the POS terminal provided with a numeric key for placing a single item code of a product, a sales point, etc., and a closing key for declaring the end of registration of one commercial transaction. Thus, the scanner 26 and the keyboard 27 constitute a product registration means.
[0016]
Each of the POS terminals 2A to 2N having such a configuration previously stores link code change data that may be changed according to the POS terminal registered for sale, among the link codes linked to the single item codes of the respective products. A link switching table 7 is provided in the RAM 23 as change data storage means for storing.
FIG. 5 shows the structure of the link switching table 7 in the first embodiment, and the link code is selectively set and stored in correspondence with the change number. Here, as shown in FIG. 3, the change number is a number that is selectively set in correspondence with the single product code unique to each product on the single product file 4, and the link code is set according to the POS terminal registered for sale. Set only for products that may change from one chained to another. The link code of the link switching table 7 is a link code after change when a product for which a corresponding change number is set is registered for sale at the POS terminal.
[0017]
Thus, in the first embodiment, the CPU 21 of each POS terminal 2A to 2N performs the merchandise sales shown in the flowchart of FIG. 7 in particular for one merchandise transaction from the sales registration of the merchandise purchased by one shopper to the payment. The program is configured to execute the registration process.
That is, when the CPU 21 determines that the single product code is input by ST (step) 1 by the barcode input from the scanner 26 or the key input from the keyboard 27 and the sales registration of the product is performed, the single product code is used as the single product code as ST2. Is sent to the file processor 1 via the communication line 3. As a result, if there is a response of single item data such as a link code, single item name, unit price, change number, etc. set in the single item file 4 corresponding to the single item code from the file processor 1, the unit price and the number of sales points in this data The sales amount is calculated from the above. Then, the sales point and the sales amount are registered in the sales registration memory of the RAM 23. In addition, the display 28 displays the name of the single item, the unit price, the number of sales points, the sales price, and the like.
[0018]
Next, the CPU 21 checks the change number in the single item data returned from the file processor 1 as ST4. Here, when the change number is “0”, the registered product is a product that aggregates sales in common with a link code linked to a single product code regardless of the POS terminal registered for sale. Sales transaction data (sales data) is created from the single product code and link code, the number of sales points and the sales amount of the registered product.
[0019]
On the other hand, if the change number is other than “0”, the link switching table 7 is searched using the change number as a key in ST6. Then, in ST7, it is determined whether or not a post-change link code is set corresponding to the change number. Here, if the change number corresponding to the link switching table 7 is not set or if the change number is set but the corresponding post-change link code is not set (= 0), the registered product is sold. Although it is a product that aggregates sales with a link code other than a link code linked to a single item code according to the registered POS terminal, if it is registered for sale at the POS terminal, the sales are aggregated with a link code linked to a single item code. Therefore, the process proceeds to the process of ST5, and sales transaction data is created from the single product code and link code in the single product data, the number of sales and the sales amount of the registered product.
[0020]
On the other hand, if a changed link code is set in the link switching table 7 in ST7 corresponding to the change number, the registered product is linked to a single product code according to the POS terminal registered for sale. This is a product that aggregates sales with a link code other than, and when it is registered for sale at the POS terminal, sales are aggregated with the above-mentioned link code. Therefore, as ST8, the single product code in the single product data and the above-mentioned link code Sales transaction data is created from the sales number and sales amount of the registered product.
[0021]
Thus, if sales transaction data is created by the processing of ST5 or ST8, the CPU 21 temporarily stores the sales transaction data in the transaction buffer of the RAM 23 as ST9. Next, in ST10, it is determined whether or not the closing key for declaring the end of product registration for one commercial transaction has been operated. Here, if the closing key is not operated, the registration of the merchandise to be sold and managed as one commercial transaction is continued, so the process returns to ST1 and the processes of ST1 to ST9 are repeated.
[0022]
If it is confirmed in ST10 that the lock key has been operated, the CPU 21 displays the total of products registered for sale in ST11 on the display 28 as ST11, or drives the printer 29 to receive a receipt. The registration closing process such as printing issuance is executed. Thereafter, when the sales transaction data temporarily stored in the transaction buffer of the RAM 23 is transferred to the file processor 1 via the communication line 3 as ST12, the merchandise sales registration process for the current one commercial transaction is terminated.
[0023]
Here, in the first embodiment, the process of ST2 in the merchandise sales registration process executed by the CPU 21 constitutes a code reading means, the processes of ST6 and 7 constitute a change target judging means, and ST5 and ST8. This process constitutes sales data creation means, and the process of ST12 constitutes sales data transfer means.
[0024]
On the other hand, in the file processor 1 that has received the sales transaction data, when the single product file 4 is searched with the single product code in the transaction data and the corresponding single product code is detected, the sales point data and the sales amount corresponding to the single product code are detected. The number of sales points and the sales amount in the transaction data are added to the data. When the link file 5 is searched with the link code in the transaction data and the corresponding link code is detected, the sales point data and the sales amount data in the transaction data are added to the sales point data and sales amount data corresponding to the link code. Are respectively added.
[0025]
For example, we want to manage sales of single batteries, AA batteries, and AA batteries sold at the food / miscellaneous goods department and the toy department in addition to the home appliance department, especially at the food / general goods department and the toy department. In this case, in the first embodiment, as shown in FIG. 3, the change number is added to each single item data of the product “single battery”, “single battery”, “AA battery” on the single product file 4. For example, “10” is set. Further, as shown in FIG. 4, in the link file 5, the data of the link code “1001” as the food department battery and the link as the toy department battery separately from the data of the link code “1000” linked to the single item code of each battery. Data with code “1002” is added. Further, in the link switching table 7 of the POS terminal (assumed to be 2A) installed in the food and sundries section, the changed link code “10” corresponding to the change number “10” as shown in FIG. "1001" is set, and the link switching table 7 of the POS terminal (assumed to be 2B) installed in the toy section is linked to the changed number "10" as shown in FIG. 5C. The code “1002” is set. In addition, in the link switching table 7 of the POS terminal (assumed to be 2N) installed in the home appliance section, the changed link code is not set for the change number “10” as shown in FIG.
[0026]
As a result, the sales of the battery registered for sale by the POS terminal 2N of the consumer electronics department are counted as the sales of the link code “1000” linked to the single product code of the battery on the link file 5, but the food and miscellaneous goods The sales of the battery registered for sale by the POS terminal 2A of the sales floor are counted as the sales of the changed link code “1001” different from the link code “1000”. Similarly, the sales of each battery registered for sale by the POS terminal 2B of the toy department are counted as the sales of the link code “1002” after the change.
[0027]
As described above, according to the first embodiment, the POS terminal 2A to 2N, as in the past, simply inputs the single product code unique to the product and registers the sales of the product, and the POS that has registered the sales of the product for sale. Depending on the terminal, it can be correctly counted as sales of different link codes. Therefore, for example, it is possible to cope with the operation of counting the sales of the product for each sales floor without changing the single item code of the same product for each sales floor, so that practicality can be improved without complication of product management.
[0028]
Next, a second embodiment corresponding to the first and third aspects of the present invention will be described with reference to FIGS.
This second embodiment is also applied to the same POS system as the first embodiment, and the outline is the same as that of the first embodiment. Description is omitted. Further, since the hardware configurations of the POS terminals 2A to 2N are the same as those of the first embodiment, description thereof will be omitted with reference to FIG.
[0029]
FIG. 6 shows the structure of the link switching table 7 in the second embodiment, and the link code is selectively set and stored corresponding to the single product code. That is, in the second embodiment, when sales are registered at the POS terminal, the link code is changed from the one linked with the single product code unique to the sales product to another one and the link after the change. Set the code.
[0030]
Thus, in the second embodiment, the CPU 21 of each POS terminal 2A to 2N performs the merchandise sales shown in the flowchart of FIG. 8 for one merchandise transaction from sales registration to price settlement of merchandise purchased by one shopper. The program is configured to execute the registration process.
That is, when CPU 21 determines that the sale of the product has been registered as ST 1, CPU 21 creates an inquiry message for the single product data using the single product code as ST 2 and transmits it to file processor 1 via communication line 3. As a result, when there is a response of single item data such as a link code, a single item name, and a unit price set in the single item file 4 corresponding to the single item code from the file processor 1, sales are performed from the unit price and the number of sales points in this data. Calculate the amount. Then, the sales point and the sales amount are registered in the sales registration memory of the RAM 23. In addition, the display 28 displays the name of the single item, the unit price, the number of sales points, the sales price, and the like.
[0031]
Next, the CPU 21 searches the link switching table 7 using the single item code input as ST4 as a key. Here, when the single product code corresponding to the link switching table 7 is not set as ST5, since the registered product is sales registered at this POS terminal, the sales are totaled by the link code linked to the single product code. In ST6, sales transaction data is created from the single product code and link code in the single product data, the number of sales points and the sales amount of the registered product.
[0032]
On the other hand, if the single product code is set in the link switching table 7 in ST5, the registered product is a link different from the link code linked to the single product code when it is registered for sale at this POS terminal. Since the sales are totaled by code, the changed link code set corresponding to the single item code is read from the link switching table 7 as ST7. Then, sales transaction data is created from the single item code in the single item data, the changed link code, the number of sales points and the sales amount of the registered product.
[0033]
Thus, if sales transaction data is created by the processing of ST6 or ST7, the CPU 21 temporarily stores the sales transaction data in the transaction buffer of the RAM 23 as ST8, as in the first embodiment. Next, in ST9, it is determined whether or not the tightening key has been operated. If the tightening key is not operated, the process returns to ST1 and repeats the processes of ST1 to ST8.
[0034]
When it is confirmed in ST9 that the closing key has been operated, the CPU 21 executes the registration closing process as ST10 and then transfers the sales transaction data to the file processor 1 as ST11, as in the first embodiment. Then, the merchandise sales registration process for the current one commercial transaction is completed.
[0035]
Here, in the second embodiment, the process of ST2 in the merchandise sales registration process executed by the CPU 21 constitutes a code reading means, the processes of ST4 and 5 constitute a change target judging means, and ST6 and ST7. This process constitutes sales data creation means, and the process of ST11 constitutes sales data transfer means.
[0036]
The file processor 1 that has received the sales transaction data updates the sales data of the single product file 4 and the link file 5 in the same manner as in the first embodiment.
[0037]
In the second embodiment having such a configuration, when the above-described battery sales management is to be realized, the link switching table 7 of the POS terminal 2A installed in the food / grocery department is shown in FIG. As shown in FIG. 6B, the changed link code “1001” is set corresponding to the single item code of each battery, and the link switching table 7 of the POS terminal 2B installed in the toy section is shown in FIG. The changed link code “1002” is set corresponding to the single item code of each battery. In the link switching table 7 of the POS terminal 2N installed in the home appliance section, the single item code and the changed link code of each battery are not set.
[0038]
As a result, the sales of the battery registered for sale by the POS terminal 2N of the consumer electronics department are counted as the sales of the link code “1000” linked to the single product code of the battery on the link file 5, but the food and miscellaneous goods The sales of the batteries registered for sale at the POS terminal 2A at the sales floor are counted as the sales of the changed link code “1001” different from the link code “1000”, and each battery registered for sale at the POS terminal 2B at the toy sales floor. Are aggregated as sales of the changed link code “1002”.
[0039]
Therefore, also in the second embodiment, the same effect as in the first embodiment can be obtained.
[0040]
In the second embodiment, since the change number can be omitted from the setting items of the single product file 4, there is an advantage that the conventional single product file 4 can be used as it is.
[0041]
【The invention's effect】
As described above in detail, according to the first to third aspects of the present invention, the link code that changes the sales of one product depending on the product sales registration device that has registered the product for sale without complication of product management. It is possible to provide a product sales registration data processing system that can be tabulated as sales of products and can improve practicality.
According to the invention of claim 2, the change number is set in the single item setting file, and the changed link code is selectively set in the change data storage means of each merchandise sales registration apparatus corresponding to the change number. Therefore, there is an advantage that the setting work for enabling the tabulation processing to be performed as sales of different link codes depending on the product sales registration apparatus that has registered the sales of one product is easy.
[0042]
Further, according to the invention described in claim 3 of the present application, it is only necessary to set a single item code and a post-change link code necessary for the change data storage means of each merchandise sales registration device, so that the setting operation is further facilitated. There is.
