The setting of the sales floor code is performed by operating the keys of the keyboard 41 in a state where the "setting" mode is selected by the mode switch 45, or by down line loading from the store processor 1.

The CPU 31 of the terminal 3
Is program-controlled to execute a product registration process shown in FIG. 5 when a single product code of a product is read by the scanner 44 while the “registration” mode is selected by the mode switch 45.

That is, when the input of the single item code is confirmed in step ST1, the single item code and the RAM 3 are checked in ST2.
The inquiry message of the single item information is edited by the sales floor code set in the sales floor code area 33a of No. 3. (Inquiry Message Creation 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 awaited. (Query message transmitting means) In response, a response message from the file processor 22 is received in ST4, and if it is confirmed in ST5 that the response is a normal response indicating the single item information, the response message is transmitted in ST6. Execute sales registration processing at unit price. (Registration processing means) Specifically, a sales price is obtained by multiplying the unit price by the sales points, and transaction data of single item sales is created from the sales amount, the sales points, and the like, and registered in the RAM 33. Also, the name of the product, the sales amount, and the like responded to at the same time as the unit price are displayed on the display unit 42, and are printed on a receipt or the like by the printer 43.

In this manner, the transaction data of the single item sales registered in the RAM 33 is collected by the file processor 2 at appropriate times, and is classified and summed up in the sales data area of the single item file 5 by the single item code.

It should be noted that an error occurs if there is no response from the file processor 2 to the inquiry message transmission of the single item information within a predetermined time, or if there is an error response.

The CPU 21 of the file processor 2
Is controlled by a program so as to execute the processing shown in FIG. 6 when receiving the inquiry message of the single item information from the terminal 3 via the communication interface 26.

That is, if it is confirmed in ST1 that the received message is an inquiry message for single item information, the single item file 5 is searched for in ST2 using the single item code and the sales floor code in the message. (File search means) When a record in which both the single item code and the sales floor code match in ST3 is detected, the record is called from the single item file 5 in ST4, and the terminal 3 inquired as a normal response to the terminal 3 via the communication interface 26. To send. (First Single Item Information Response Means) If a record in which both the single item code and the sales floor code match cannot be detected in ST3, ST5.
The single item file 5 is searched using only the single item code in the inquiry message. (File re-search means)

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 terminal 3 inquired through the communication interface 26.
(Second single item information response means)

If a record having the same single item code is not detected in ST6, an error response without single item information is created in ST7, and transmitted to the terminal 3 that has been queried via the communication interface 26.

In a large store in which the POS system of the present embodiment configured as described above is introduced, the single item information of the item sold at each counter is set in the single item file 5 in advance. In this case, for a product sold only at one sales floor, the sales floor code of the sales floor is set together with the single item code, name, unit price, and the like of the product. For products sold at different sales floors at different unit prices, 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 at a plurality of sales floors, a sales floor code of a typical sales floor or sales floor code = 0 is set together with a single item code, name, unit price, and the like.

In this state, when a single item code is read by the scanner 44 in the “registration” mode at the terminal 3, an inquiry message of unit price information is entered 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 using the single item code and the sales floor code in the received inquiry message. If there is single item information in which the single item code and the sales floor code match in the single item file 5, the single item information is called and transmitted to the terminal 3 which has made the inquiry.

On the other hand, if 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 using only the single item code. Then, when there is single item information having the same single item code, the single item information is called and transmitted to the terminal 3 which has made the inquiry. If there is no single item information with the same single item code, an error response is transmitted.

In the terminal 3, upon receiving the single item information, registration processing of the item sales data is performed based on the single item information. If an error response is received, an error occurs because the single item information has not been set.

As described above, according to the present embodiment, for a product sold at a plurality of sales floors at different unit prices, a single product code, a name, a unit price, a sales floor code, and the like are set in the single product file 5 for each sales floor. By searching the file 5 only once, the unit price corresponding to the sales floor can be called. Therefore, it is possible to reduce the processing time required to call an accurate unit price matching the sales floor, and further to reduce the processing time required to register a product having a different unit price for each sales floor.

For products other than products having different unit prices for each sales floor, the sales floor code in the single item information is always set to “0”, and the single item file 5 is searched by the single item code and the sales floor code in the inquiry message. If there is no corresponding single item information, single item code and sales floor code “0” in the inquiry message
May be programmed to search for the single item file 5.

In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0039]

As described above in detail, according to the present invention, in a product sold at a plurality of sales floors, for a product having a different unit price depending on the sales floor, a single product code and a sales floor of the sales floor to be sold are stored in a single product file. By setting the code and unit price at the sales floor, the product can be registered at the unit price according to the sales floor. For products whose unit prices do not differ depending on the sales floor, the single item code of the product and the sales floor As long as the unit price is set, the product can be registered at the unit price common to the sales floor. Therefore, it is possible to reduce the processing time required for registering products having different unit prices depending on the sales floor, and it is not necessary to set a single product code and a unit price for each sales floor in a single product file for products whose unit prices do not differ according to the sales floor, and the storage capacity of the single product file is reduced. It is possible to provide a merchandise sales data processing device that can be saved.
