The terminals 3 are distributed and installed in each sales floor, and the sales floor code of the sales floor is set in the sales floor code area 33a of the RAM 33 for use. It should be noted that the setting of the sales floor code is performed by operating the keys of the keyboard 41 with the "setting" mode being selected by the mode switch 45, or by down line loading from the store processor 1.

Then, the CPU 31 of the terminal 3
When the "register" mode is selected by the mode switch 45 and the scanner 44 reads the individual product code, the program is controlled to execute the product registration process shown in FIG.

That is, when the input of the single product code is confirmed in step ST1, the single product code and the RAM 3 are confirmed in ST2.
The inquiry message of the single item information is edited with the sales floor code set in the sales floor code area 33a of 3. (Inquiry message creating means) Then, in ST3, the inquiry message is transmitted to the file processor 2 via the communication interface 34, and a response from the file processor 2 is waited. (Inquiry message transmitting means) In response, in ST4, the response message from the file processor 22 is received, and in ST5, when it is confirmed that the response is a normal response indicating single item information, the response message is transmitted in ST6. The sales registration process is executed at the unit price of. (Registration Processing Means) Specifically, the unit price is multiplied by the number of sales points to obtain the sales amount, transaction data of single item sales is created from the sales amount, the number of sales points, etc., and registered in the RAM 33. Further, the name of the product and the amount of sale which have been responded to at the same time as the unit price are displayed on the display 42 and printed on the receipt or the like by the printer 43.

In this way, the transaction data of the single item sales registered in the RAM 33 is collected by the file processor 2 at appropriate times, and classified into individual item codes in the sales data area of the single item file 5 and totaled.

If the file processor 2 does not respond to the inquiry message transmission of the single item information within a predetermined time, or if there is an error response, an error occurs.

Further, the CPU 21 of the file processor 2
Is controlled by a program so as to execute the processing shown in FIG. 6 when it receives an inquiry message for single item information from the terminal 3 through the communication interface 26.

That is, if it is confirmed in ST1 that the received message is an inquiry message for single item information, in ST2 the single item file 5 is searched by the single item code and the sales floor code in the message. (File Retrieval Means) Then, in ST3, when a record in which the single item code and the sales floor code match is detected, the record is called from the single item file 5 in ST4 and sent to the terminal 3 inquired as a normal response via the communication interface 26. Send. (Single Item Information Responding Means) If a record in which the single item code and the sales floor code match cannot be detected in ST3, the single item file 5 is searched using only the single item code in the inquiry message in ST5.

When a record having the same single item code is detected in ST6, the record is called from the single item file 5 in ST4 and transmitted as a normal response to the inquired terminal 3 via the communication interface 26.

When a record having a matching single product code is not detected in ST6, an error response without single product information is created in ST7 and transmitted to the inquired terminal 3 via the communication interface 26.

In a large-scale store in which the POS system of this embodiment having the above-mentioned structure is introduced, the single-item information of the products sold at each sales floor is set in the single-item file 5 in advance. In this case, for a product that is sold only in one sales floor, the sales floor code of the sales floor is set together with the individual product code, name, unit price, and the like of the product. For products that are sold at different unit prices at multiple sales floors, a single item code, name, unit price, sales floor code, etc. are set for each sales floor. For a product sold at the same price in a plurality of sales areas, a sales area code of a representative sales area or a sales area code = 0 is set together with a single item code, a name, a unit price, and the like.

In this state, when the scanner 44 reads the single item code in the "registration" mode at the terminal 3, the unit price information inquiry message is transmitted between the single item code and the sales floor code of the sales floor where the terminal 3 is installed. Is created and transmitted to the file processor 2.

Then, the file processor 2 searches the single item file 5 by the single item code and the sales floor code in the received inquiry message. Then, when the single item information in which the single item code and the sales floor code match is present in the single item file 5, the single item information is called and transmitted to the terminal 3 which made the inquiry.

On the other hand, when there is no single item information in which the single item code and the sales floor code match in the single item file 5, the single item file 5 is searched again only by the single item code. Then, when there is single-piece information in which the single-piece code matches, the single-piece information is called and transmitted to the inquiring terminal 3. If there is no single item information with the same single item code, an error response is transmitted.

In the terminal 3, when the single item information is received, the product sales data is registered based on the single item information. If an error response is received, an error will occur because the single item information has not been set.

As described above, according to this embodiment, the products sold at different unit prices in a plurality of sales floors are set in the single product file 5 by setting a single product code, a name, a unit price, a sales space code, etc. By searching the file 5 once, the unit price corresponding to the sales floor can be called. Therefore, it is possible to shorten the processing time required to call an accurate unit price that matches the sales floor, and further shorten the processing time required to register a product having a different unit price for each sales floor.

For products other than products whose unit price differs from store to store, the store code of the single item information is always set to "0", and the single item file 5 is searched by the single item code and the store code in the inquiry message. If the corresponding single item information does not exist, the single item code and sales floor code “0” in the inquiry message
You may program so that the single item file 5 may be searched with.

Besides, it is needless to say that various modifications can be made without departing from the scope of the present invention.

[0039]

As described above in detail, according to the present invention, the unit price that matches the sales floor of a product whose unit price differs depending on the sales floor is 1
It is possible to provide a merchandise sales data processing device that can detect and perform registration processing only by searching one table, and can reduce the processing time required for registration.
