Further, transmission control circuits 15 and 16 are connected to the CPU 11, and the host model 2 and the master machine 8 or satellite machines 9 _{1 to} 9 _n are connected.
It is connected to the.

 Next, the operation of the above embodiment will be described.

First, when the capacity of the commodity table 4 is designated from the master machine 8, the file controller 6 secures the designated area of the transaction table 5.

After that, when the product code, name, unit price, etc. of the product are set in the product table 4 by the master machine 8 or the higher-level model 2, the file controller 6 searches the product table 4 arranged in the ascending order of the code. Then, if there is a setting from the master machine 8 or the higher-level model 2, it is confirmed whether or not there is a code, if there is no code, it is added, if there is a code, it is changed, and processing is performed according to the flowchart of FIG. .

First, it is determined whether or not the unit price has been changed (step 1), and if the unit price is not changed, the processing is performed as it is. When the unit price is changed, the product sales data including the code of the corresponding code, the product name, the old unit price, the number of sales, and the sales amount is created from the product table 4 (step 2). At this time, it is judged whether or not it is set to write to the floppy disk 13 (step 3), and when it is set to write to the floppy disk 13, it is stored in the floppy disk 13 (step 4), and the floppy disk is set. When it is not necessary to write in 13, the transaction is stored in the transaction table 5 of the center file 7 (step 5), and the process ends.

Also describes the registration from the satellite unit 9 ₁ to 9 _n. The same applies when the master machine 8 operates as a satellite machine 9 ₁ to 9 _n.

Further, when receiving the inquiry code from the satellite unit 9 ₁ to 9 _n or master unit 8 searches for the code of the product from the product table 4 of the file controller 6. Also,
If the code of the product exists, the necessary message such as the name and unit price is taken out, and if the code does not exist, the no-code error is transmitted from the transmission control circuit 16.

Then, the file controller 6 causes the satellite machines 9 ₁ to
9 _n or affection transfected data from the master device 8, that is, memory processes sales number and sales amount of the product table 4 searches the code from the product table 4 receives the data memory process.

Next, a specific example of the above operation will be described with reference to a table and FIG.

The table shows changes over time in the product table code 00123.

(1) in the table shows a state in which 150 pieces of caramel of code 00123 are sold at a unit price of 50 yen, for a total of 7,500 yen. For example, if the unit price is changed from 50 yen to 40 yen at 10:00, it will be as shown in (2) of the table. At this time, a transaction occurs, and transaction 1 shown in FIG. 5 is stored in transaction table 5. That is, for example, the time when the unit price is changed, the code, the old unit price, the number of sales, and the amount of sales are stored as the control header. In this state, 260 more, 10,400
When yen sales occur, it becomes as shown in (3) of the table. Furthermore, for example, when the unit price is changed from 40 yen to 50 yen again at 14:00, it becomes as shown in (4) of the table, and Tran 2 occurs,
As shown in FIG. 6, transaction 2 is stored in transaction table 5. Then, the sales number and sales amount when the unit price of Tran 1 shown in Fig. 6 is 50 yen are shown, and the sales number and the sales amount when the difference between Tran 2 and Tran 1 is 40 yen are shown. Become.

Then, when a request for sales data information is made to the file controller 6 from the host model 2 via inline or online, the file controller 6 sends transaction data for each unit price change to the transaction table 5 of the file controller 6 or the floppy disk. Read from 13 and transmit to host model 2. Further, in the high-end model 2, the sales data for each unit price received is calculated for each unit price data of the code, and as shown in FIG. 7, the number of sales and the amount of sales are printed and output for each unit price.

〔The invention's effect〕

According to the POS system of the present invention, the sales unit data and the sales amount data stored in the product table are updated for each code for classifying the products based on the product information transmitted from the electronic cash register, and the product is transferred from the master machine. When the changed unit price data of is set, the sales unit data and sales amount data immediately before this product stored in the product table are newly stored in the auxiliary table corresponding to the code, and the auxiliary table is responded to in response to the information collection request. Since the file controller outputs the sales quantity data and the sales amount data stored in each code individually, it is not necessary to set the unit price changed for each electronic cash register as in the past, and the information collection request Accordingly, the sales quantity data and sales amount data stored in the auxiliary table are printed out individually for each code. Therefore, rather than simply sales quantity is outputted, it is possible to obtain information on sales quantity data and sales amount data for each was changed bids can grasp the sales situation for each bid.
