Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention stores in advance the special unit price and the grouped special sale period of each product for sale in addition to the normal unit price of each product for sale in a file control unit, and performs unit price setting change work. This invention relates to a simplified POS system.

[Prior art] Generally, in a PO3 (point of sale) system adopted in supermarkets, department stores, etc., 1
A plurality of electronic cash registers are connected to one file control unit (FC) via transmission lines. Product data such as product codes, product names, unit prices, etc. of all products sold at each sales floor are stored, for example, by product code in a product data memory formed in the storage of the file control unit.

Then, when the product code attached to the sales product is read using a barcode scanner or the like at each electronic cash register, this product code is incorporated into the product data inquiry message and transmitted to the file control unit. The file control unit searches for the product code in the product data memory using the product code included in the received inquiry message, reads out the product name and unit price of the corresponding product code, incorporates them into the response message, and sends them back to the corresponding electronic cash register. do. Upon receiving the response message, the electronic cash register uses the product data such as product name and unit price included in the response message to carry out sales registration processing for the sales product. Then, sales data such as the number of sales items and sales amount as a registration result is transmitted to the file control section.

In a POS system configured in this way, the product data for all products sold at each sales floor is stored all at once in the product data memory of the file control unit, so when you start selling a new product, or when you are already selling a product, you When changing the unit price of a product, etc., it is only necessary to change the settings in the product data memory of the file control section.

[Problems to be Solved by the Invention] However, the above-described POS system also has the following problems. In other words, when changing the unit price of a product that is already on sale, for example, enter the product code of the product whose unit price is to be changed and the unit price after the change from the master electronic cash register of multiple electronic cash registers connected to the file control unit. Key human power is required.

Note that some systems allow the product code to be entered using a barcode scanner.

However, in supermarkets and the like, the unit prices of products are often changed. Also, depending on the product, you can set a certain sale period in advance, such as at the end of the fiscal year or the end of the month, and set the unit price of the product to a lower price than the normal price during that sale period. After the special sale period ends, the product may be sold at the original regular price.

In such a case, it is necessary to change the unit price of the product to the special sale price when the sale period begins, and then return the unit price to the original normal price when the sale period ends. Therefore, there is a problem in that the time required to change the unit price increases.

Furthermore, if the unit prices of many products are changed frequently, there is a concern that the unit prices of the wrong products may be changed due to key human errors, or that incorrect unit prices may be set.

The present invention has been made based on the above circumstances, and its purpose is to store in advance the special price and grouped special price period of each sale product in addition to the normal unit price of each product in the file control unit. To provide a POS system which can simplify the unit price change work between the normal unit price and the special sale unit price, improve the efficiency of the entire sales operation, and prevent erroneous setting of the unit price etc. due to erroneous operation.

[Means for Solving the Problems] As shown in FIG. 1, the present invention transmits a product code input through the input device 2 of each electronic cash register 1 to the file control unit 3 as a product data inquiry. POS that executes a sales registration process 6 using the unit price 5 read out and returned from the product data memory 4 of the file control unit.
In the system, the file control unit 3 includes a bargain price memory 7 that stores the bargain price of each product stored in the product data memory 4, and a bargain group memory 8 that stores the bargain group to which this product belongs for each product. A sale period memory 9 for storing predetermined sale periods for each sale group, and a sale flag 1G for storing whether or not each product is currently in the sale period are provided, and the flag updating means 11 can: In response to a flag update command 12 from the outside, the sale flag 10 of each product belonging to the sale group of the sale period that includes the current time in each sale period in the sale period memory 9 is set to be on sale, and the sale unit price is set to be on sale. The reply means 13 responds to the product data inquiry input from each electronic cash register 1 and sends the special sale unit price stored in the special sale unit price memory 7 to the corresponding electronic cash register 1 when the sale flag 10 of the corresponding product specifies that it is on sale. It was designed to reply to.

Another invention is that in the POS system of the above invention, instead of the flag updating means 11 described above, an automatic flag updating means 14 is used to store a sale period memory in response to an interrupt signal from an internal clock circuit at predetermined intervals. The sale flag 10 of each product belonging to the sale group of the sale period that includes the current time among the sale periods 9 is set to be on sale.

[Operation] In the POS system configured as described above, the regular unit price is stored in the product data memory of the file control unit, and the special unit price is stored in the special sale unit price memory. Further, each product belongs to each sale group that is grouped according to the sale period, and whether or not it is in the sale period is specified by a sale flag. Then, when a file update command is input from the outside, the sale flag of each product of the group whose current time is during the sale period is set to be on sale.

When a product data inquiry is input from the electronic cash register, if the product's sale flag indicates that the product is on sale, the sale unit price of the product is transmitted to the electronic cash register.

Another advantage of the invention is that, in the above-mentioned operation, the sale flag of each product is automatically updated by an interrupt signal from an internal clock circuit at predetermined intervals, rather than by an external flag update command. Automatically updated according to the current time. Therefore, a strong sale flag is always set.

A product data memory R1 is formed in the RAM 55 as shown in FIG. This product data memory R1
Inside are: 9 product code areas for storing product codes for each product on sale; 9 product name areas for storing product names; 1 normal unit price memory for storing normal unit prices; R2; special unit price memory for storing special sale unit prices; and special sale period to which the product belongs. Special sale group memory R4 stores the group numbers of groups grouped by period, flag area R5 stores a special sale flag indicating whether this product is currently in the special sale period, and the sales number and sales of this product. A sales area R6 and the like for storing amounts and the like is formed.

Also, a special sale period memory R7 as shown in FIG. 7 is formed in the RAM 55. The sale period memory R7 stores the sale start year, month, day, hour and minute and the sale end year, month, day, hour and minute for each group number.

FIG. 8 is a diagram showing a key operation procedure in the master electronic cash register 22 when setting a sale period in the sale period memory R7 of the file control section 21 of FIG. That is, after setting the control key 36 to the [master] business mode, the setting business in the sale period memory R7 is specified using the number key 33 and the date key [80]. Next, specify the sale period setting mode using [1] and the date key, then input the group number and X key using the numeric keys 33, and then input the year, month, day, hour, and minute of the sale start using the numeric keys 33. Furthermore, the end date and time of the special sale period are entered manually.

Thus, the CPU 37 of the master electronic cash register 22 is programmed to execute the flow chart of FIG. In other words, the keyboard 27 at Pl
When a key signal is input from , after confirming that the control key 36 is set to [Master] business mode, the input key signal is set to the numeric key 33 of [36] and #.
If it is a combination key signal with a key, the flag update command is incorporated into the message format and transmitted to the file control unit 21 via the transmission path 24.

Also, in Pl, instead of the key signal from the keyboard 27,
If the product code from the barcode scanner 32 is entered at P2, the control key 36 is set to [Register].
Make sure it is set to business mode. and,
The input product code is incorporated into the product data inquiry message format shown in FIG. 11(a), and the file control unit 2
Send to 1.

As shown in the figure, the message format of the product data inquiry consists of a header indicating the type of message, an electronic cash register number (ECRNQ), and a product code.

At P3, the file control unit 21 sends the command (Cb) or (
When a response message containing product data as shown in message format C) is received, registration processing of sales products is performed based on this product data.

In other words, the product name and unit price of the product data are displayed on the display section 28゜29.
The sales amount is displayed on the screen, printed out on the receipt, and added to the internal totalizer. At the same time, sales data consisting of a product code, number of items sold, and sales amount are incorporated into the message format shown in FIG. 11(d) and transmitted to the file control section 21.

FIG. 10 is a flowchart showing the operation of the CPU 51 of the file control section 21. That is, when a flag update command is input from the master electronic cash register 22 at P4,
At P5, the current year, month, day, hour, and minute A are read from the clock circuit 67. Next, the group number of the sale period corresponding to the year, month, and day A that was previously read out is searched from the sale period memory R7. Next, special sale group memory R4 of product data memory R1
The on-sale flag in the flag area R5 of each product belonging to the corresponding group number is set to 1, and the on-sale flag of the products belonging to the other groups is reset to O.

This completes the flag update process.

Furthermore, at P6 each electronic cash register 22.23
When a product data inquiry message is input from , the corresponding product code is searched in the product data memory R1. Then, product data such as the product name 2 normal unit price, special sale unit price, and special sale flag of the corresponding product code are read out. If the sale flag read in Pl is set to 1, this product is in the sale period, so as shown in Figure 11(b), the product name, sale unit price, and Product data such as the sale flag is incorporated into the message format and transmitted to the corresponding electronic cash register 22,23.

If the on-sale flag read in Pl is cleared to 0, this product is not on sale, so the flag in Figure 11 (c)
), product data such as the product name 9 of the corresponding product code, normal unit price, and sale flag are incorporated into a message format and transmitted to the corresponding electronic cash register 22, 23.

At P8, each electronic cash register 22.23 to 1st
When the message format incorporating the sales data shown in FIG. 1(d) is received, the number of sales items and sales amount of this sales data are added to the number of sales items and sales amount of the corresponding product in the sales area R6.

With a POS system configured in this way, two types of unit prices, a normal unit price and a special sale price, are always set for each product in the file control unit 21, so that the two types of unit prices, the regular unit price and the special sale price, are always set in the file control unit 21. There is no need to manually change the actual unit price for each product twice.

Furthermore, by dividing each product into a plurality of groups for each sale period and specifying only the number of that group when changing the unit price, the unit prices of all products belonging to that group can be changed. For example, by simply transmitting a flag update command from the master electronic cash register 22 to the file control unit 21 every morning when the store opens, products that fall under the current sale period are automatically sold at the sale unit price.

In this way, since unit price changing operations can be easily performed, the work efficiency of the entire sales operation can be improved. Furthermore, the probability of occurrence of incorrect unit price settings due to key operation errors when changing unit prices can be significantly reduced, so the reliability of the entire POS system can be improved.

FIG. 12 and FIG. 13 show the PO according to the embodiment of the present invention.
3 is a flowchart for explaining the operation of the file control unit of the S system. In this embodiment, as shown in FIG. 12, the flag update process is executed not by a flag update command from the master electronic cash register 22, but by a time interrupt process from the clock circuit 67 at predetermined intervals. That is, when an interrupt signal is input from the clock circuit 67 at one-minute intervals, the processes from P5 onward in FIG. 10 are executed.

13 is the same as the processing after P6 in FIG. 10.

In a POS system configured in this manner, each on-sale flag in the flag area R5 corresponding to each product in the product data memory R1 of the file control unit 21 is automatically updated every minute based on the latest time information. Since it is updated, each unit price dynamically changes to a special sale price or returns to a normal unit price in response to the sale period without sending a special command from the master electronic cash register 22. Therefore, the aforementioned effects can be further improved.

Furthermore, by adjusting the interval at which the interrupt processing shown in FIG. 12 is performed, it is possible to set up a special sale period for fresh foods, for example, after a specific time every day.

[Effects of the Invention] As explained above, according to the present invention, in addition to the regular unit price of each sale item, the special sale unit price and grouped sale period are stored in advance in the file control unit.

Therefore, the work of changing the unit price between the normal unit price and the special sale unit price can be simplified, the efficiency of the entire sales operation can be improved, and erroneous setting of the unit price etc. due to erroneous operation can be prevented.
