Abstract

PROBLEM TO BE SOLVED: To manage a stock with correctness where difference to a permissible degree is satisfied while unnecessitating complicated scrapping input work and stocktaking work. SOLUTION: A stock memory classified by the production date of each commodity is provided, the stock quantity of the production date concerned of the commodity concerned is added and updated at the time of buying the commodity and the stock quantity of the production date concerned of the commodity concerned is subtracted and updated at the time of selling the commodity. In addition to it, presence or absence of passage in an effective sales period as against the respective production dates is normally managed and the stock quantity for the portion of the production date concerned of the commodity concerned is automatically erased (S29) when the commodity of the production date, whose effective sales period elapses within a stock memory exists (S24-Y). The stock quantity for the portion to be scrapped without being sold since the effective sales period elapses from the production date is automatically erased and processed so that the input operation of the scrapped portion and stocktaking work become unnecessary.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product sales registration data processing device such as a POS system.

[0002]

2. Description of the Related Art Generally, in various stores, a purchase input operation is performed when a product is purchased or received, a sale input operation is performed when the product is sold, and a discard input is performed when an old product is discarded. By performing operations, inventory management of products is performed for each product on a ledger or a memory of the POS system.

However, the actual inventory amount is usually different from the inventory amount on the book or in the memory of the POS system due to an input error relating to purchasing, selling, discarding, theft or loss. Therefore, in reality, the stocktaking work is periodically performed, and the input operation is performed again so that the inventory amount on the ledger or the memory of the POS system matches the actual inventory amount.

[0004]

The inventory work is indispensable for accurate inventory management, but the inventory work is a very troublesome work and the sales work must be stopped during that time. There is a problem in terms of sales.

Further, it is considered that the burden of such inventory work is still light if the product is a small number of products, such as once in half a year or seasonally. However, for example, perishable foods handled in supermarkets and convenience stores, and products such as bento whose effective sales period from the manufacturing date is limited to a relatively short period, are discarded if unsold after the period. Therefore, it is necessary to frequently perform the input processing or the stocktaking work of the waste, which cannot be endured. Therefore, even in the case of a product having a relatively short effective sales period, it is the fact that the frequency of inputting of waste and inventory work is reduced, knowing that accurate inventory management cannot be performed.

[0006] Therefore, an object of the present invention is to provide a product sales registration data processing device capable of performing inventory management with accuracy that can be accommodated within an allowable error while eliminating the troublesome disposal input work and inventory work. .

[0007]

According to a first aspect of the present invention, there is provided product information input means for inputting product information including manufacturing date information, and an inventory memory for storing an inventory amount of each product by manufacturing date. A sales period memory that stores an effective sales period from the manufacturing date set for each product group, and a timekeeping unit that measures the current date and time, and the product information input by the product information input unit when purchasing the product Based on the product, the stock amount of the corresponding product in the stock memory on the corresponding manufacturing date is added and updated. At the time of selling the product, the stock amount of the product on the corresponding manufacturing date in the stock memory is calculated based on the product information input by the product information input means. Products that have been manufactured for which the effective sales period has elapsed in the inventory memory based on each manufacturing date information and the current date and time information obtained from the timekeeping means at the time of subtraction update and settlement If there was to clear the inventory of the relevant date of manufacture amount of the relevant goods. According to the second aspect of the present invention, product information input means for inputting product information including manufacturing date information, an inventory memory for storing an inventory amount for each product by manufacturing date, and a manufacturing date set for each product group. Sales period memory for storing the effective sales period from, the time measuring means for measuring the current date and time, and the corresponding manufacturing date of the corresponding product in the inventory memory based on the product information input by the product information input means at the time of purchasing the product. And a stock amount subtraction and update means for updating and updating the stock amount and a stock amount subtraction for updating and updating the stock amount of the corresponding product in the stock memory on the corresponding manufacturing date based on the product information input by the product information input means at the time of sale of the product. There is a product on the manufacturing date for which the effective sales period has elapsed in the inventory memory based on the updating means, each manufacturing date information at the time of settlement, and the current date and time information obtained from the timing means. If there is a product for which the effective sales period has elapsed as a result of the determination by the sales period elapse determination means and the sales period elapse determination means, delete the inventory quantity of the relevant production date for the relevant product. And a means for erasing the inventory amount.

Therefore, each product has an inventory memory for each manufacturing date, the stock amount of the corresponding manufacturing date of the corresponding product is added and updated when the product is purchased, and the stock amount of the corresponding manufacturing date of the corresponding product is updated when the product is sold. Subtract and update. As a result, the stock amount is basically adjusted. In addition, whether or not the effective sales period for each manufacturing date has elapsed is constantly managed, and if there is a product on the manufacturing date for which the effective sales period has elapsed in the inventory memory, the product for that manufacturing date Automatically clear inventory. Since these products for which the effective sales period has passed from the manufacturing date have been discarded without being sold, the input operation of the discarded items becomes unnecessary by automatically erasing the inventory amount. In addition, at the time of this erasure, since the actual disposal amount and loss due to theft etc. are not considered, the actual inventory amount and the inventory amount in the memory do not necessarily match, but all the mismatched items have passed the effective sales period. Eventually, it will be surely removed from the sales floor and the inventory quantity will become 0, so that it will automatically coincide with the actual inventory quantity after a certain period of time, and the inventory work becomes unnecessary. In other words, even if inventory is not taken, the disagreement will disappear like natural selection, and the stuff will be in tune with the passage of a certain period.

According to a third aspect of the present invention, in addition to the product sales registration data processing apparatus according to the second aspect, the name of the product whose inventory quantity is deleted from the inventory memory by the inventory quantity erasing means, the erased quantity, and the individual corresponding commodity It has an output means for outputting a disposal report including information such as the amount of money, the total price of all applicable products, and the like.

Therefore, with respect to the product to be discarded as the effective sales period elapses, the inventory amount for the manufacturing date is automatically deleted and the disposal report of the corresponding product is output. Disposal of merchandise can be performed easily and surely, and it is possible to prevent the credit loss of the store due to the expired merchandise remaining in the sales floor.

According to a fourth aspect of the present invention, in addition to the commodity sales registration data processing apparatus according to the second aspect, for each corresponding commodity whose inventory quantity is erased from the inventory memory by the inventory quantity erasing means,
It has an output means for outputting a product-by-product / day-by-day disposal report including information such as the erasure amount and the amount of money by manufacturing date, the total amount of erasure and the total amount of money, together with the name of the product.

[0012] Therefore, as for the products to be discarded due to the lapse of the effective sales period, the inventory amount for the manufacturing date is automatically deleted, and the product-by-product / daily-disposal report is output. By analyzing the report content,
In order to reduce the amount of waste as much as possible, it can be effectively used for future adjustment and planning of the purchase amount.

[0013]

An embodiment of the present invention will be described with reference to the drawings. The product sales registration data processing device of the present invention, as one of its embodiments, for example, fresh food,
It is applied to POS terminals in POS systems at convenience stores that handle products such as bento. The hardware configuration will be described with reference to FIG.

This POS terminal uses a CP as a control unit body.
It is equipped with U1. This CPU 1 has a bus line 2
Via the ROM 3 in which fixed data such as a program is stored in advance, or R for temporarily storing variable data.
AM4 is connected.

The CPU 1 has a host interface 5 for connecting to a host computer of a host device via a bus line 2, a keyboard controller 7 for controlling a keyboard 6, and a display controller for controlling a display 8. 9, a printer controller 11 for controlling the receipt / journal printer 10, a two-dimensional data code reader interface (including a decoder) 13 for inputting a two-dimensional data code read by the two-dimensional data code reader 12, a mode switch 14, Drawer opening device 1 for opening a drawer (not shown)
5 is connected to the I / O port 16 and the like.
Reference numeral 17 denotes a clock circuit which is a clock means for clocking the current date and time (year / month / day / day of the week).

As shown in FIG. 3, the mode switch 14 is a key switch for selecting various business modes such as "registration", "inspection", "accounting", "setting", etc. It is also possible to select the business mode "purchasing".

The keyboard 6 is, as shown in FIG.
Various keys necessary for inputting operations in various business modes are arranged and constitute one of the product information inputting means. Specifically, the department key 6a, the number key 6b, the subtotal key 6c, the deposit / cash total key 6d for declaring closing, the clear key 6e, PL
A U key 6f, an inventory key 6g, a # key 6h, etc. are arranged.

The display device 8 displays the name of the product registered for sale, the selling price, the payment amount of one transaction, and other items as appropriate. The display device for the clerk operating the POS terminal and the display for the customer. And an indicator.

The printer 10 has the names of all the products registered for sale in one transaction on receipt paper and journal paper,
It prints the sales price, total amount, etc. The printed paper is ejected by the receipt issuing port, cut for each transaction and issued to the customer as a receipt.
It is wound inside the OS terminal and stored as a transaction history. Further, the receipt paper is also used for outputting a disposal report and the like which will be described later.

The two-dimensional data code reader 12 has two
A dimensional code, for example, a rectangular two-dimensional data code 18 in which various data are arranged in a matrix having a configuration in which at least two pieces around the dimensional code are linear as shown in FIG. Make up one of.

Here, the two-dimensional data code 18 is created independently at the time of manufacture of a product in a store, or is created by a maker and given individually to each product. In such a two-dimensional data code 18, for example, as shown in FIG. 6, "product code""product name (kana)""product name (kanji)""departmentcode""first selling price"" Various product data such as “cost”, “manufacturing date”, “second selling price”, and “discount amount” are appropriately included.

In the RAM 4, P as shown in FIG.
A storage area for the LU memory 21 and the transaction memory 22 as shown in FIG. 8 is secured.

The PLU memory 21 stores the product code column 21a, the product name column 21b, and the department code column 21 as usual.
c, unit price column 21d, sales period column 21e, multiple manufacturing date / inventory column 21f, inventory total column 21g, sales point column 21h, sales amount column 21i, discard point / disposal amount column 21j by day of the week, discard 21k point meter column, 21m discard amount column,
Etc. Here, in the sales period column 21e, effective sales period information from the manufacturing date is set for each product group (the minimum unit of the group is each product), and functions as the sales period memory 23. For example, in the case of a product that is to be discarded without being sold after 3 days from the manufacturing date, “3” is set as the sales period. The manufacturing date / inventory column 21f functions as an inventory memory 24 that stores the inventory amount for each product by manufacturing date (by manufacturing date), and at least the number of days of the effective sales period is secured for each product. . The discard point / disposal amount column 21j for each day of the week is automatically erased and discarded by the inventory amount erasing process described later for each day of the week from Monday to Sunday (depending on the product, not all days are required). It stores the number of disposal points treated as disposal and the amount of disposal amount corresponding thereto, and functions as a day-of-week disposal memory 25.

The transaction memory 22 also includes a discard point column 22a and a discard amount column 22b.

Each function of the inventory amount addition updating means, the inventory amount subtracting updating means, the sales period lapse judging means, the inventory amount erasing means and the output means, which will be described later, is executed by the CPU 1 in accordance with a program stored in the ROM 3. It is configured to run.

Next, processing control of inventory management according to various business modes will be described with reference to the flow charts shown in FIGS. 1 and 9 to 13.

First, the mode switch 14 is set to the "purchase" business mode, the two-dimensional data code 18 attached to the purchased product is read by the two-dimensional data code reader 12, and the number of products (the number of purchases) is set. ) Is input by the number key 6b and the # key 6h is pressed, the inventory amount addition updating means executes the process shown in the flowchart of FIG. In this case, instead of inputting the product information by the two-dimensional data code reader 12, the product code and the manufacturing date information may be input from the keyboard 6.

In the purchasing operation mode shown in FIG. 9, when product information is input by the two-dimensional data code reader 12, the two-dimensional data code reader interface 1
It is converted into the data content as shown in FIG. 6 by the decoder in 3, and the product code is read from the data. Then, it is searched whether a product code corresponding to the product code exists in the PLU memory 21 (step S).
1). In this search, if it does not exist in the PLU memory 21 (N of S2), it is a new product that has not been registered in the PLU memory 21, so the product code, product name, department code read from the two-dimensional data code 18, Information such as sales price and manufacturing date is set in the PLU memory 21 (S
3). Then, regardless of whether the product is newly registered or already registered, the manufacturing date / stock column 21 in the PLU memory 21
It is checked whether or not f has the same date as the manufacturing date of the product purchased this time (S4). This is because the same product may be stocked in the morning and afternoon even on the same day, and they are processed on the same manufacturing date.

If there is no same manufacturing date (N in S4), it is a new manufacturing date, so the manufacturing date / stock column 21f
In the column in which the stock amount is 0, the manufacturing date and the quantity of the product purchased this time are rewritten and stored (S5). If there is already the same manufacturing date (Y in S4), the stock amount in the manufacturing date / inventory column 21f of the corresponding manufacturing date is added and updated by the amount of the current purchase (S6). After the processing of step S5 or S6, the added amount in the processing is also added to the inventory total column 21g (S7).

In this way, every time a product is purchased, the stock amount of the corresponding product on the manufacturing date in the manufacturing date inventory memory 24 is the inventory amount based on the product information input by the two-dimensional data code reader 12 and the keyboard 6. The addition is updated by the addition updating means.

Next, the mode switch 14 is set to the business mode of "registration", and the number of products (sales point) is entered by the number key 6b.
The two-dimensional data code 18 is replaced by the two-dimensional data code reader 12
The inventory amount subtraction update means executes the processing as shown in the flowchart of FIG.

In the merchandise registration business mode shown in FIG. 10, when merchandise information is input by the two-dimensional data code reader 12, the decoder in the two-dimensional data code reader interface 13 converts it into the data content as shown in FIG. , Read the product code from the data.
And the product code corresponding to the product code is PLU.
It is searched whether or not it exists in the memory 21 (S11). In this search, if it does not exist in the PLU memory 21 (N of S12), since it is an error, other processing such as error processing is performed. On the other hand, if it exists normally (S
12 Y), it is checked whether or not the corresponding product has passed the effective sales period (S13). That is, the manufacturing date information of the corresponding product in the read two-dimensional data code 18 is subtracted from the current date and time (today's date) obtained from the timing circuit 17, and the number of days is set in the sales period column 21e for the corresponding product. Check whether the effective sales period has expired. If it exceeds the limit, error processing such as sales prohibition is performed. As a result, old products whose effective sales period has expired will not be mistakenly sold.

In the case of a product that has not exceeded the effective sales period, it is a normal sale, so the inventory amount in the manufacturing date / inventory column 21f of the relevant manufacturing date of the relevant product in the PLU memory 21 is equal to the number of sales points. Subtract and update (S14). Then, the subtracted amount in this process is also subtracted in the inventory total column 21g (S15). Further, this sales amount is added to the sales amount column 21h (S16), and this sales amount (that is, points × unit price) is added to the sales amount column 21i (S17).

In this way, each time a product is registered for sale, the inventory amount and inventory amount of the relevant product in the production date inventory memory 24 are calculated based on the product information entered by the two-dimensional data code reader 12. Is subtracted and updated by the stock amount subtraction update means, and the sales points and sales amount are additionally updated.

Further, by setting the mode switch 14 to the "payment" business mode and pressing the deposit / cash total key 6d on the keyboard 6, the processing shown in the flowchart of FIG. 1 is executed.

In the settlement operation mode shown in FIG. 1, P
Based on the information of the sales number column 21h and the sales amount column 21i stored in the LU memory 21, the sales number and the sales amount of each product are printed on the receipt paper by the receipt printer, and the output processing of the sales report for each product is issued. Perform (S21), after the report is issued, the sales point column 21
h, the information in the sales amount column 21i is deleted (S22). Such processing is executed for all products in the PLU memory 21 (S23).

Next, with respect to each product in the PLU memory 21, it is checked whether or not each of the manufacturing date / inventory columns 21f has an effective sales period that has passed today (S24). That is, the manufacturing date information in the manufacturing date / stock column 21f is subtracted from the current date and time (today's date) obtained from the timing circuit 17, and the number of days is the sales period column 2 for the product.
It is checked whether or not the effective sales period set in 1e is exceeded. If it exceeds, it is checked whether the stock quantity on the manufacturing date is 0 (S25). The processing in step S25 is executed by the sales period elapse determination means. If the effective sale period has not been exceeded, or if the inventory has already run out even if it has exceeded the valid sale period, proceed to the next product, but if there is a manufacturing date with inventory remaining beyond the effective sale period. In addition, the number of stocks corresponding to the manufacturing date is added to the discard point column of the corresponding day of the week in the discard memory 25, and the discard amount is calculated by the calculation of (stock number) × (unit price). It is added to the discard amount column which is paired with the discard point column of the day of the week (S26). The addition of the discard points and the discard amount is also performed for the discard point total column 21k and the discard amount total column 21m. further,
A discard point column 22a and a discard amount column 22 in the transaction memory 22
Also for b, the addition processing of the discard points and the discard amount is performed (S27).

With respect to the products to be discarded in this way,
The merchandise code, merchandise name, manufacturing date, the number of stocks to be discarded, and the amount are printed on the receipt paper by the receipt printer (S28). Then, the stock quantity of the corresponding product on the corresponding manufacturing date is deleted (S29). In this way, the processing is performed for all products in the PLU memory 21 (S30). Therefore, the discard information in step S28 is printed on the receipt paper for the relevant product / manufacturing date, and is finally printed out as a product-based discard report 31 as shown in FIG. Therefore, the manager or the like can see the contents of the product-by-product disposal report 31 to identify the product of the manufacturing date that has expired and should be disposed of. Therefore, the product can be easily and surely disposed of from the sales floor. it can. The processing of step S28 is executed by the output means. In addition, step S29
The above process is executed by the inventory amount erasing means.

After that, the contents of the transaction memory 22 including information such as the number of discarded points and the amount of discard are printed and issued as a transaction report (S31), and the transaction memory 22 is cleared (S3).
2) End the process.

In this way, for example, in the settlement work performed at the end of the work for one day, the inventory memory 2 for each production date is used.
For items for which the valid sales period has passed from the manufacturing date, the inventory amount for the relevant manufacturing date is automatically erased by the inventory amount erasing means. There is no need to do it one by one. Even if the stock quantity on the PLU memory 21 is cleared on the manufacturing date, the corresponding product actually remains in the sales floor and may differ from the actual stock quantity, but the product is sold at least. There is a temporary time lag, because it will be discarded without exception and eventually the number of stock will be 0.
Eventually the tsuji will fit. This is because even if the number of products in the sales floor decreases due to theft or damage and does not match the number in stock in the memory, these are equated with the discarded items due to expiration, so the inventory amount over time Tsuji will be fit. Therefore, these allow inventory management without requiring troublesome inventory work.

By the way, the mode switch 14 is inspected.
Set the business mode to become the stock key 6 on the keyboard 6.
By pressing g, the all stock inspection process as shown in the flowchart of FIG. 11 is executed. That is, for a product whose data in the inventory total column 21g is not 0 in the PLU memory 21, the product code, product name, number of stocks, and the manufacturing date and the number of stocks in the inventory memory 24 by the manufacturing date when the number of stocks is not 0 are received. The printer prints on receipt paper (S41), and repeats this for all products in the PLU memory 21 (S42), thereby issuing a full inventory report. FIG. 15 shows an example of such an inventory report 32. In the example shown in the figure, a prominent discrimination mark 33 such as “☆” is attached to a product on a manufacturing date when the effective sales period is approaching, and prompt sales are promoted.

Further, after the mode switch 14 is set to the business mode of "inspection" and the product code of the desired product is input by the numeral keys 6b on the keyboard 6 (the input may be made by the two-dimensional data code reader 12). Stock key 6g
By pressing, the individual inventory inspection process as shown in the flowchart of FIG. 12 is executed. First, it is checked whether or not the product code exists in the PLU memory 21 (S43), and if it does not exist, other processing such as error processing is performed. If there is, the product code of the corresponding product, The product name, the number of stocks, and the manufacturing date and the number of stocks in the inventory memory 24 by which the number of stocks is not 0 are displayed on the display unit 8 and printed on the receipt paper by the receipt printer (S44). Further, the contents of the day-by-day discard memory 25 of the relevant product (that is, the number of discard points and the discard amount for each day of the week)
Further, the contents of the discard point count column 21k and the discard amount column 21m are displayed on the display 8 and printed on the receipt paper by the receipt printer (S45).

Further, the mode switch 14 is set to the "payment" business mode, and the stock key 6g is placed on the keyboard 6.
By pressing, the discard settlement process as shown in the flowchart of FIG. 13 is executed. That is, regarding the product whose data in the discard point column 21k and the discard amount total column 21m in the PLU memory 21 is not 0, its product code, product name,
The contents of the day-by-day discard memory 25 (that is, the number of discard points and the amount of discard for each day of the week), the total number of discard points, and the total amount of discard are printed on the receipt paper by the receipt printer (S46),
At the same time, the discard memory 25 for each day of the week, the discard point column 21k, and the discard amount total column 21m are cleared (S47), and this is PLU.
By repeating all products in the memory 21 (S48), the product-by-product / daily-disposal report is issued. The processing of step S46 is executed by the output means. FIG. 16 shows an example of such a product / daily disposal report 34. Therefore, such product / daily disposal report 34
By studying and analyzing the contents of the above, it is possible to know the manufacturing dates, etc. where sales are unsuccessful, and it is possible to effectively utilize them for purchasing plans, etc., in which the amount of unsold stock will be reduced as much as possible.

In this case, instead of, or in addition to, the discard report indicating absolute numerical values, the discard rate report 35 having the discard rate as shown in FIG. 17 may be printed out. If so, you can understand the rate of disposal,
You can make a more appropriate sales plan.

By the way, in the present embodiment, as shown in FIG. 18, the normal selling period for switching the selling price within the effective selling period is set in the normal selling period column 21n in the PLU memory 21. A second unit price column 21p in which two unit prices are set is also prepared. For example, for a product with an effective sales period of 3 days from the date of manufacture, set 2 days from the date of manufacture as the normal sales period in order to prevent unsold items as much as possible and promote sales. This is because they are sold cheaply. Such second unit price information is appropriately included in the two-dimensional data code 18 attached to each product according to the product.

In the product registration process described above with reference to FIG. 10, the stock subtraction process of the PLU memory 21 has been mainly described, but regarding the sales registration process in consideration of the normal sales period, refer to the flowchart shown in FIG. Explain. As in the case of FIG. 10, the mode switch 14 is set to the business mode of “registration”, and the number of products (sales points) is entered by the numerical key 6b, and the two-dimensional data attached to the sales registered product is entered. By reading the code 18 with the two-dimensional data code reader 12, the processing as shown in the flowchart of FIG. 19 is executed.

In the merchandise registration business mode shown in FIG. 19, when merchandise information is input by the two-dimensional data code reader 12, the decoder in the two-dimensional data code reader interface 13 converts it into the data content as shown in FIG. , Read the product code from the data.
And the product code corresponding to the product code is PLU.
It is searched whether or not it exists in the memory 21 (S11). In this search, if it does not exist in the PLU memory 21 (N of S12), since it is an error, other processing such as error processing is performed. On the other hand, if it exists normally (S
12), it is checked whether or not the corresponding product has passed the normal sales period (S51). That is, the manufacturing date information of the corresponding product in the read two-dimensional data code 18 is subtracted from the current date and time (today's date) obtained from the timing circuit 17, and the number of days is the normal sales period column 21n for the corresponding product.
Check whether the normal sales period set in is exceeded. If not, the first selling unit price is read from the unit price column 21c of the PLU memory 21 (S52),
In the sales amount column 21i for the product (first selling unit price) ×
The sales amount calculated from (score) is added (S53), and the product name and the sales amount are displayed on the display 8 and printed on the receipt paper (S54). On the other hand, if it is determined in step S51 that the normal sales period has expired, the second sales unit price is read from the second unit price column 21p of the PLU memory 21 (S55), and then the sales amount column 21i of the product. Is added to the sales amount calculated by (second sales unit price) × (score) (S53), and the product name and the sales amount are displayed on the display 8 and printed on the receipt paper (S54). .

Therefore, the regular sale period is set for the product for which the effective sale period is set, and the product for which the normal sale period has elapsed even within the effective sale period is automatically discounted. Since it is sold, it is possible to provide a discount service without forcing the cashier to perform a special operation and without forgetting to overlook the discount as in the case of the discount seal.

In order to carry out the discount processing with the passage of such a normal sales period, the discount amount column 21 as shown in FIG. 18 together without setting the second unit price.
q is set to set the discount amount, or the discount rate column 2
Processing may be performed by providing 1r and setting a discount rate.

FIG. 20 shows the processing control in this case. If it is determined in step S51 that the normal sales period has expired, the first sales unit price is read from the unit price column 21c of the PLU memory 21 as in step S52 (S56).
In the sales amount column 21i for the product (first selling unit price) ×
The sales amount calculated from (score) is added (S57), and the product name and the sales amount are displayed on the display 8 and printed on the receipt paper (S58). After this, the discount amount is read from the discount amount column 21q (S59),
Subtract (score) x (discount amount) from the sales amount (S6
0) Then, the discount amount is displayed on the display 8 and printed on the receipt paper (S61). Alternatively, the discount rate column 21r
The discount rate is read from (S59), and (score) × (sales unit price) × (discount rate) is subtracted from the sales amount (S60),
The discount amount is displayed on the display 8 and printed on the receipt paper (S61).

FIG. 21 shows an example of printing a receipt 36 issued when such a discount process is involved.

In the present embodiment, a certain POS terminal has the PLU memory 21 and manages the inventory. However, the host device such as the file server and the host computer constituting the POS system uses the PLU memory. Own,
Each POS terminal may be configured to transmit the product code of the product and the manufacturing date information to the upper device side, and the upper device side may collectively manage the inventory in the PLU memory. Further, in the present embodiment, storage fields such as unit price (first and second) and effective sales period are prepared in advance in the PLU memory 21, but
By using the data holding amount of the two-dimensional data code 18, the two-dimensional data code 18 itself may hold such information. However, there is no problem even if the commodity sales form uses a normal bar code instead of the two-dimensional data code 18.

In this embodiment, the discard report 3
