BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a POS system, and more particularly, to a POS system that can easily manage product data and sales data.

[0002]

2. Description of the Related Art In a conventional POS system, an auxiliary storage device such as a disk stores the product information (data section) of each product such as a product code, product price, and product name, and the sales amount and sales points of the product. It has a product file that holds sales information (accumulator part) for each product, and the update of the data part and the totalization of the accumulator part have their own procedures for the store processor and the POS terminal that make up the POS system. .

In such a POS system, in order to define, change, or delete product information, the store processor creates update data and transfers it to the POS terminal, and the POS terminal uses the update data to read the data portion of the product file. The POS terminal collects the sales information and transfers it to the store processor for totaling sales information.
It has a function of totaling sales information of OS terminals, which complicates file management. Therefore, a dedicated store processor is connected. A POS terminal used in this type of POS system is disclosed in, for example, Japanese Patent Laid-Open No. 1-14.
There is one disclosed in Japanese Patent No. 0289.

[0004]

By the way, recently, the number of products handled by retail stores is increasing, and since they are being operated for a long time, information managed by the POS terminal and the store processor is not available. It is increasing and it takes a lot of time to process it.

For this reason, the POS terminal has a function capable of operating alone, but as described in the prior art,
Update and transfer of product files can be done by other POS terminals,
This is not easy because of the relationship with the store processor.

[0006] Therefore, a new POS terminal opening operation, a settlement operation totalized by the store processor, and a POS operation.
It is not easy to update files while handling the terminal, and in order to do so, it is necessary to restrict other tasks.

It is an object of the present invention to provide a POS system capable of improving a file system and a business procedure associated therewith so as to easily execute a business which cannot be easily performed by the above-mentioned conventional techniques.

In addition to the fact that the POS terminal can be operated as a single unit, a file format, file transfer means, etc. are provided as standard to facilitate connection with the store processor, and the POS terminal can be updated by the store processor to provide the PO.
Make file management in the POS terminal and store processor independent, such as making the reference only in the S terminal or updating it in the POS terminal and making it reference only in the store processor Sales, inspection, settlement, maintenance It is intended to provide a means for reducing the load in business such as.

[0009]

The above object is to provide a POS system for managing product information, which comprises a store processor, which is a high-order computer, and a POS terminal equipped with product code input means, storage means and control means.
In the storage means, a data section file consisting of a set of product information including a product code necessary for product registration and a product price, and an accumulator section file holding sales data including the product code of the product and the number of sales are separately provided. As a file, the control means reads necessary product information from the data part file of the product code in response to the input of the product code during the product registration process, creates product registration information, and stores it in the accumulator part file. Then, the accumulator section file is transferred according to an instruction from the store processor, and the data section file is updated according to an instruction from the store processor when the product information is changed.

Further, when there is no data in the data section file of the POS terminal during the merchandise registration processing, the store processor is queried to obtain merchandise information, and merchandise registration information is created and stored in the accumulator section file. This eliminates the need to update the data section at the POS terminal, and allows the store processor to easily manage the product master.

The storage means may further have a second data section file in addition to the data section file, and the second data section file can be changed at the POS terminal, so that the POS terminal can individually change the second data section file. It is also possible to perform the product registration processing of.

Furthermore, by having a plurality of accumulator units for different purposes, the store processor can easily collect only necessary items.

[0013]

[Operation] Separate data section consisting of a set of information of each product such as product code, product price, product name, etc. necessary for product registration and accumulator part for accumulating sales data such as sales amount and sales points for each product By having it as a file and updating the data part with the store processor and making the POS terminal read-only, the data part can be centrally managed by the store processor and the data part can be updated regardless of whether sales are made at the POS terminal. At the same time, the accumulator section is updated at the POS terminal and the store processor is exclusively used for reading. The POS terminal updates the data section by adding the key code to the record of the accumulator section only for the sold data. It has the function to output without referring to the file, and the data section and accumulator section are independent. To be able to be processed.

By dividing the data section and the accumulator section, the information amount of each file can be reduced,
It is possible to reduce the load of transfer of the data part from the store processor at the time of processing for opening a new POS terminal, and to reduce the load of transfer of the accumulator part to the store processor at the time of aggregation processing.

It is an accumulator section file. The POS terminal is composed of the control unit 102, the input unit 104, the output unit 105, and the storage unit 106 shown in FIG.

FIG. 2 describes the details of the data section file 161. As shown in FIG. 2, the data section file 161 is composed of a set of product information for each product, and the record of each product is composed of a product code, a product name, a price, and other additional information.

FIG. 3 describes the details of the transaction data file 162. As shown in FIG. 3, the transaction data file 162 is composed of a set of product information (product code, product price, product name, etc.) and sales information (sales amount, sales points, etc.) of each transaction. There is.

FIG. 4 shows the accumulator section file 163.
This is a description of the details of. As shown in FIG. 4, the accumulator section file 163 is composed of a set of sales information for each product, the record for each product is composed of sales amount, points, etc., and each sales information is a product code. Attach.

FIG. 5 shows the control unit 102 of the POS terminal.
5 is a flowchart showing a product registration process (performed by referring to a data part which is one of the divided files) in FIG. In step 501, the product code is input to the keyboard 141,
Alternatively, when input by the scanner 142, step 502
At, the data section file 161 is searched to obtain the corresponding product information. Next, based on the product information acquired in step 503, 1
Create transaction data for each product. 1 in step 504
When the product registration for the transaction is completed and payment processing is started,
In step 505, transaction data (payment information) for one transaction is created. Finally, in step 506, the transaction data for one transaction is stored in the transaction data file 162. In this merchandise processing, it is not necessary to access the accumulator section file and the data section is not updated.

FIG. 6 is a flowchart showing the updating process of the accumulator section file which is one of the divided files in the POS terminal. The updating process of the accumulator unit is performed by the control unit 102 of the POS terminal. The timing of performing the updating process can be freely set depending on the number of transactions, time value, etc., but in the present embodiment, it is updated for each transaction. When one transaction ends, in step 601, data for one transaction is read from the transaction data file 162. Next, the accumulator unit 163 is updated based on the transaction data read in step 602. The accumulator section file is updated using the product code as a key. At this time, there is no need to access the data section file.

As described above, the data part and the accumulator part which are divided into files at the POS terminal are referred to separately,
Even by updating, sales registration and cumulative sales processing can be realized. The store processor collects store sales information,
When managing the inventory information, the transfer instruction of the accumulator section file 163 is instructed to each POS terminal. The POS terminal receiving the transfer command transfers the accumulator section file to the store processor at that time.

The settlement processing of the POS terminal can be realized only by the accumulator section file without referring to the data section file.

Even at the time of inspection from the store processor, this can be realized by transferring only the accumulator section file to the accumulator section file.

When the data part such as the price of the product is changed, the store processor updates the data part file collectively or partially. When performing a batch update, the updated data section file is distributed from the store processor to the POS terminal and a batch update request is issued. PO
The S terminal side updates the data section file when requested. On the POS terminal side, data that can be changed according to a transaction is stored in a separate file in the data section file, so the data section file can be updated when a request is made without paying attention to the stored transaction information. it can.

The store processor stores the data section file in P
Regardless of the state of the OS terminal, it is always in a state where it can be updated, and if the POS terminal is informed each time it is updated, the POS terminal only needs to transfer files between transactions, so the store processor does not need to be aware of the state of the POS terminal. The update function can be realized.

If the POS terminal determines the file transfer timing individually, the data section file can be updated without affecting the sales registration although a slight deviation occurs for each POS terminal.

As described above, if the data section file and the accumulator section file are divided to realize sales registration and sales cumulative processing, it is possible to shorten the processing time of file inspection, settlement, maintenance functions and the like. .

When there is no data in the data section file of the POS terminal during the merchandise registration process, the store processor is queried to obtain merchandise information, create merchandise registration information, and store it in the accumulator section file. This eliminates the need to update the data section at the POS terminal, and allows the store processor to easily manage the product master.

The storage means may further have a second data section file in addition to the data section file, and the second data section file can be changed at the POS terminal, so that the second data section file can be individually changed by the POS terminal. It is also possible to perform the product registration processing of.

Further, by having a plurality of accumulator units for each purpose, the store processor can easily collect only necessary items.

[0032]

As described above, according to the present invention,
By dividing the data section and the accumulator section into files, the file management of the POS terminal and the store processor can be separated, and the data section can be centrally managed by the store processor, regardless of the sales at the POS terminal. Can be updated only by file transfer from the store processor. Further, the accumulator unit can update only the products that have been sold at the POS terminal, and by adding the key code, it is possible to output without referring to the file in the data unit.
As described above, since the POS terminal can be operated independently, the POS terminal can be provided as a single unit and has no special restrictions other than the file format and the file transfer means, and can be easily connected to the store processor.
