Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a product sales system in which a store control section is connected to a file control section provided with a tally file, and a plurality of terminals are connected to this file control section. The present invention relates to a data processing device.

[Technical background of the invention and its problems]

In department stores, supermarkets, etc. that handle a large number of products, product sales data processing equipment, so-called product sales data processing equipment, performs sales management, inventory management, and purchasing management using product numbers such as JAN codes assigned to each product.
POS (Point of Sales) systems are beginning to be adopted.

Such a POS system, for example, connects electronic cash registers (ECRs, hereinafter referred to as registers) as multiple terminals installed in a sales floor to one file control unit, and then connects this file control unit to this file control unit. A store control section that controls a file control section is connected. The file control unit stores the above-mentioned product number set for each product sold on the sales floor, the number of sales of the product with this product number,
A tally file is provided that stores a plurality of registered data including sales amounts and the like. Then, each time a product is registered for sale in each register, registration data such as the product number of the sold product, number of sales items, sales amount, etc. is sent from the register to the file control section, and based on this registration data, the file control section The number of sales items, sales amount, etc. of the registered data of the corresponding product number in the summary file provided in the . Then, at the end of the day, the store control section performs settlement operations based on each registered data transmitted from the file control section. In addition, the store control section
Sends a command to set the product number in the total file to the file control unit.

In such a POS system, generally,
In addition to the total file, an auxiliary area is provided within the file control section. In the register, if a product whose product number is not stored in the above-mentioned summary file is registered for sale, only the number of sales items and sales amount of the registered data are stored in the above-mentioned auxiliary area without distinguishing the product number, and a new In addition, each time registered data whose product number was not set in the summary file was generated, the number of sales items and sales amount of that registered data was added to the previously stored number of sales items and sales amount.

However, in a POS system that stores the registered data of products whose product numbers are not set in the summary file in the auxiliary area without distinguishing between the product numbers, the above products are not distinguished at the time of checkout and are stored all at once. Calculated as other sales points and sales amount. As a result, accurate product sales, settlement, inventory, and purchasing management were not possible. Additionally, there was a problem in which the store control unit could not immediately determine which product numbers were not set in the summary file.

[Purpose of the invention]

The present invention has been made based on the above circumstances, and its purpose is to store registered data for which no product number has been set in an empty area of a tally file, including the product number. To provide a product sales data processing device that can greatly suppress the amount of data stored in an area, obtain accurate payment results, and carry out sales, payment, inventory, and purchase management of qualified products.

[Summary of the invention]

The present invention provides a status area for storing status information for each product number indicating whether the product number is set by own processing or by the store control unit, and also provides an empty area in the summary file. . Then, if the product number of the registered data sent from each terminal is set in the summary file, the file control unit updates the registered data of the corresponding product number in the summary file based on that registration data, and updates the registered data of the corresponding product number in the summary file based on that registration data. In this case, it detects free space in the summary file, sets the corresponding product number in that free space, and then aggregates the registered data, and also checks that the product number has been set in the status area corresponding to the product number by its own processing. This is a product sales data processing device that stores information indicating the storage area and, if no free area is detected, totals registered data corresponding to the auxiliary area.

[Embodiments of the invention]

FIG. 1 is a schematic configuration diagram of a POS system according to an embodiment of the present invention.

In the POS system of this embodiment, a plurality of electronic cash registers 1 are installed in each sales floor.
(ECR, hereinafter abbreviated as register) is connected in series to one file control unit (FC) 3 via transmission line 2, and store control is sent to this file control unit 3 via transmission lines 4a and 4b. (SC) 5 is connected.

FIG. 2 is a block diagram of the file control section (SC) 5. As shown in FIG. The CPU (central processing unit) 6 is
Built-in arithmetic circuit, command register, etc., each register (ECR) 1 and store control section (SC)
5 performs various arithmetic processing based on the input information from the ROM 8, RAM 9, and tally file 10 as storage devices, and the SC transmission control circuit 11 as an input/output device via the data bus 7.
The ECR transmission control circuit 12 and the LED control circuit 13 are operated. The store control unit (SC) is connected to the SC transmission control circuit 11 via transmission lines 4a and 4b.
5 is connected, and the ECR transmission control circuit 12
Each register (ECR) 1 is connected to via a transmission line 2. Furthermore, in the LED control circuit 13,
Indicator light 1 composed of light emitting diodes (LEDs)
4 is connected, and is configured to control the lighting of the indicator light while the CPU 6 is executing the above-mentioned arithmetic processing.

For example, as shown in FIG. 3, the aggregation file 10 can store a plurality of pieces of registered data (200 pieces in this embodiment) consisting of the product number set for each product, status, sales amount, and number of sales items. An area is provided in which a predetermined amount of registered data is already stored. The above status indicates the setting state of the product number of the registered data to which this status belongs, and when the above product number is set by a command from the store control unit 5, it is set to "0".
If the area is newly set as a free area by the registration data from register 1 by own processing, it is set to "1". Furthermore, this total file 10 is provided with an auxiliary area 15 consisting of two areas: a sales amount area and a sales points area.

Each of the registers 1 performs product sales registration and money transfer operations, and also transmits registration data of sold products to the file control section 3 via the transmission path 2. The store control section 5 road 4b
The product number is set in the tally file 10 of the file control section 3 via the file control section 3, and settlement operations are performed based on each registered data accumulated in the tally file 10.

When setting a new product number in the area of the total file 10 of the file control unit 3, or when setting the product number of an additional product, the store control unit 5 and the CPU 6 of the file control unit 3 follow the flowchart in FIG. It is configured to operate based on That is, the store control unit (SC) 5 inquires of the file control unit (FC) 3 how many pieces of registered data are stored, that is, the number of product numbers that can be set.
In response to the above inquiry, the file control unit 3 transmits the settable number of product numbers. The store control section 5 edits newly set product numbers that are less than the settable number into a message format as shown in FIG. 5a. In other words, this message format incorporates information indicating that a product number is to be set at the beginning of the transmission, and connects, for example, n product numbers in sequence after the beginning of the transmission. . Then, this message format is transferred to the transmission line 4b.
It is transmitted to the SC transmission control circuit 11 of the file control unit 3 via. The file control unit 3 checks whether each product number incorporated in the received message format has already been set in the tally file 10.
If the corresponding product number has already been set in P1,
The received product number is temporarily stored in another storage area such as RAM9. If the corresponding product number has not yet been set in P1, the corresponding product number is stored in the area at the next address of the area where the product number is already stored. Further, "0" is stored in the status storage section of the registered data area where this product number is stored. However,
At P2, all the received product numbers are saved in the summary file 10, except for the product numbers that have already been set above.
After confirming that the file number has been set, the file control unit 3 transmits a product number setting completion signal to the store control unit 5, and also sends the duplicate product number temporarily stored in another storage area such as the RAM 9 to the store control unit 5. and simultaneously send the information to , and complete the product number setting process.

Next, when updating the registered data in the summary file 10 based on the registered data from register 1, the CPU of register 1 and file control unit 3
6 is configured to operate based on the flowchart of FIG. That is, when a product is registered for sale in register 1, register 1 edits the registered data such as the product number, sales amount, and number of sales items of the product to be sold into the message format shown in FIG. It is transmitted to the ECR transmission control circuit 12 of the intermediary file control section 3. The file control unit 3 searches the total file 10 for a product number that is the same as the product number of the registered data incorporated in the received message format (product number detection means), and if the corresponding product number has already been set in P3, The sales amount and number of sales points of the received registered data are added to the sales amount and number of sales points of the registered data of the corresponding product number in the aggregation file 10, and the updating of the registered data is completed (first data aggregation means). If the corresponding product number is not set in P3, search for free space in the tally file 10 to store the registered data (free space detection means), and P4
If there is a free area, the corresponding product number is stored in the product number area of the free area, and "1" is stored in the newly provided status storage section adjacent to this product number area. Then, the sales amount and number of sales items of the registered data are set in the empty area where the product number is newly set (second data aggregation means). If no free space is detected in P4, only the sales amount and sales points of the registered data from register 1 are added to the sales amount and sales points stored in the sales amount area and sales points area of auxiliary area 15. (third data aggregation means), and ends the registration data update work.

Furthermore, for example, when performing settlement/inspection work based on each registered data accumulated in the tally file 10 at the end of the day's work, the store control unit 5
The CPU 6 of the file control unit 3 is configured to operate based on the flowchart shown in FIG. That is, the store control unit 5 requests the file control unit 3 to transmit the total file information of the total file 10, that is, each registered data. Upon receiving the request signal, the file control unit 3 reads out the registered data of the number that can be transmitted at one time from the tally file 10 at P5, and edits it into a message format as shown in FIG. 5c. That is, this message format incorporates information indicating that registration data is to be transmitted at the beginning of the transmission, and after the beginning of the transmission, for example, n pieces of information shown in FIG.
Registered data consisting of product number, status, sales amount, and number of sales items as shown in the figure is sequentially connected. Then, in P6, it is determined whether the registered data edited into the message format includes the final registered data in the total file 10. If there is still registered data to be transmitted, information indicating that it is not the final message format is incorporated at the beginning of the transmission of the message format, and this message format is sent to the store control unit via the transmission path 4a. Send to 5. The store control unit 5, which has received this message format, notifies the file control unit 3 of the reception, requests transmission of the next registration data, and returns to P5. If the registered data edited in the message format at P6 includes the final one, this message format is the final delivery, so the message format will be indicated at the beginning of the transmission of this message format. The information shown is incorporated and transmitted to the store control unit 5. Incidentally, the sales amount and the number of sales points in the preliminary area 15 are also transmitted to the store control section 5. The store control unit 5 that has collected all the registered data performs settlement and inspection based on this registered data. When performing an inspection, it is checked whether a new product number has been set in the tally file 10 based on a request from the register 1. At P7, search for product numbers for which the status of each registered data is "1".
If the corresponding product number is detected at P7, the product number is output and displayed on a cathode ray display tube (CRT), printer, etc. Then, the above product number is added to the product number list of the store control section 5, and a change command is sent to the file control section 3 to change the status of the corresponding product number in the tally file 10 to "0". Then, the payment and inspection work is completed.

With a POS system configured like this,
When registration data of a product number that has not been set in advance by the store control unit 5 is sent from the register 1 to the file control unit 3 in the tally file 10, an empty area in the tally file 10 is searched and the above-mentioned data is stored in this empty area. The product number is set and registered data is stored. Then, only when there is no more free space, the registered data is stored in the spare area. Therefore, the amount of registration data other than the product number stored in the auxiliary area can be significantly reduced. Therefore, even if the product number is not set in the tally file 10 at the time of sales registration, accurate payment results such as the sales amount and number of items sold can be obtained for each product number at the time of checkout, so the corresponding product number and order slip,
By comparing purchase slips, etc., it is possible to perform sales, settlement, inventory, and purchase management of eligible products.

Further, in the present invention, the summary file 10
Stores a status that distinguishes whether the product number setting is based on a command from the store control unit 5 or based on its own processing using registered data from the register 1. Therefore, the store control unit 5 can immediately determine which product numbers are not registered in the store control unit's product number list by searching for product numbers whose status indicates "1" in the tally file 10. It is possible to promptly resolve problems in product management.

〔Effect of the invention〕

As explained above, according to the present invention, even if registered data with no part number set in the summary file is sent from the terminal to the file control unit, as long as there is free space in the summary file, the corresponding registered data will be counted. The data is aggregated for each product number in the file, and when there is no free space in the summary file, it is only aggregated in the auxiliary area, which greatly reduces the amount of data stored in the auxiliary area. Since the registered data is also aggregated for each product number in the aggregation file, accurate settlement results can be obtained, and it is possible to carry out sales, settlement, inventory, and purchase management of eligible products.

In addition, we have created a status area in the summary file that stores status information for each product number, indicating whether the product number was set by its own processing or by the store control unit. This also has the advantage that it is possible to easily grasp product numbers that have not been set in the tally file by the store control unit from the status information.
