[Industrial application field]

The present invention relates to a registered product code update control system, and relates to a PO8 installed at a cash register in a supermarket, retail store, etc.
The present invention relates to a registered product code update control method that allows smooth code updating when registering a product code in a terminal device.

At these cash registers, sellers and buyers are particularly requested to ensure smooth checkout.

[Conventional technology]

BACKGROUND ART Conventionally, in a POS system commonly used in the retail industry, a plurality of product codes are registered in advance in a main registration means provided at a remote or on-site center. A PO3 terminal is installed at a cash register where products are actually sold, and the PO8 terminal device is equipped with a terminal registration means.

Typically, the storage capacity of the terminal registration means is smaller than that of the main registration means.

The registered product code is sent from the main registration means on the center side to the terminal registration means installed in this POS terminal device, and is registered in the terminal registration means.

At the cash register where the customer brings the product, the code attached to the product (for example, JAN) is read.
code) is read by a reading means such as a barcode reader using a laser scanner. The code read is
The code group stored in the terminal registration means is searched to obtain the price, information on the type of the product, etc., and the cashier is informed of the sales price, and the center is given information such as management of the sales products. transmit information for

This makes it possible to sell products brought by customers, and allows the seller to obtain various information about the sold products, allowing for efficient tabulation and product management.

[Problem that the invention seeks to solve]

By the way, in the above-mentioned conventional system, the product code is transmitted from the main registration means on the center side to the terminal registration means of the POS terminal device on the cash register side for all the products displayed at the retail store where the terminal control means is installed. It is assumed that it is registered.

However, there are cases where the product code is not registered from the center side to the PO8 terminal side in the terminal registration means on the PO8 terminal side of the retail store where the terminal control means is installed. For example, when a new product arrives at a retail store, code registration from the center may be delayed. In addition, for products that are sold only in a certain season, the registered products in the terminal registration means of the POS terminal device are deleted, and for products in the next season, the product registration is updated, so there is no need to worry about unsold products, etc. If the customer brought the code, even if it was read by the reader, the code was not registered in the terminal registration means, so automatic accounting processing could not be performed.

If such automatic accounting is not possible, the cashier operator inputs the price from the keyboard included in the POS terminal to process the slip and collect money. Also, since a similar situation occurs with the same product, the cashier temporarily stops work and immediately reports to the center.
It was notified that the product was unregistered. The center operator who received the notification: 1. The main control means is operated to send an unregistered product code from the main registration means to the terminal registration means on the POS terminal side, and the code is registered in the terminal registration means. As a result, even if the next customer brings the same product, the reading means will automatically read more items and the sales process will be possible.

However, until the product code is registered in the terminal registration means on the PO3 terminal side, as long as the customer brings the product in question, the cashier operator is required to constantly input keys, and due to business suspension, etc. For this reason, there was a problem in that the efficiency of sales processing was extremely low.

Furthermore, there is a problem in that the cashier needs to contact the center regarding reading errors due to non-registration in the terminal registration means, which places a heavy burden on the cashier operator.

This kind of problem can be solved if the store where the PO8 terminal is installed is close to the location where the main control means on the center side is installed, making it easier to notify such non-registration. However, if the store where the PO8 terminal is installed is far away from the center, notifications must be made by telephone, etc., which poses the problem of extremely poor administrative efficiency.

The present invention was created in view of these points, and from the standpoint of streamlining product sales operations, which is an advantage of installing a POS system, the present invention was created by adding product information to the terminal registration means on the POS terminal side. The purpose of the present invention is to provide a registered product code update control method that enables efficient management of PO8 terminal cash registers and rational management of sales products even if the products are unregistered.

With such a configuration, one center control device 200 and multiple PoS terminal devices 250 installed in the same premises
A POS system is formed.

Figure 3 shows the PoS terminal device 250 during information exchange between the PoS terminal device 250 side and the center control device 200 side in the registered product code update control system of the embodiment of the present invention shown in Figure 2. The processing order of the terminal control unit 221 is shown below.

FIG. 4 shows a message edited on the PO8 terminal device 250 side and transmitted to the center control device 200 in the registered product code update control system according to the embodiment of the present invention shown in FIG. FIG. 5 shows the PoS terminal device 250 in the registered product code update control system according to the embodiment of the present invention shown in FIG.

(i) R code to PO3 terminal The recording operator uses the keyboard 2 of the center control device 200.
33 to input the product code of the product that has arrived at the retail store and is to be displayed on the shelf. The input product code is registered in the main storage unit 211 by the store controller 213. In this way, the product codes of products handled at this retail store are registered as soon as they arrive.

Note that for products that are no longer handled, the operator operates the keyboard 233 each time to cancel the registration.

For products normally sold at this store, an operator operates the keyboard 233 from the center control device 200 to start providing a registered product code to the PoS terminal device 250 managed by the center control device 200. do. In response, the store controller 213 retrieves a plurality of product codes registered in the main storage section 211 and transmits them to the PO8 terminal device 250 via the private line 241.

On the PoS terminal device 250 side, the center control device 200
The terminal control section 221 receives a plurality of product codes received from the terminal, supplies them to the terminal storage section 215, and registers them. As a result, products can be sold at the cash register where this PO3 terminal device 250 is installed.

Accounting processing becomes possible.

(ii) Reading 0 at the end of PO3P' We will explain the operations of reading, selling, and accounting for the products brought by the purchasing customer using the PO8 terminal device 250 in which the product code has been registered as described above.

When a customer brings the products lined up at the store to the cash register, the cash register operator scans them with the barcode scanner 217.
The code (for example, JAN code) attached to the product to be read is read (step 311).
). Hereinafter, this code will be referred to as the PLU code.

The terminal control unit 221 to which the code read by the barcode scanner 217 is supplied searches for the registration code corresponding to the read code from the terminal storage unit 215 in order to refer to the selling price and product name of the product (step 31
2). That is, the terminal control unit 221 determines whether or not a registration code corresponding to the read code exists in the terminal storage unit 215 (step 313).

If the registration code of the product corresponding to the read code exists in the terminal storage unit 215 (affirmative determination), the price and name of the product are extracted from the corresponding code. The terminal control unit 221 also displays the extracted product price on the display unit 255.
At the same time, the product price and product name are printed by the printer 257 (step 314).
).

In this way, when the transaction for one product is completed, the terminal control unit 2
21 edits a message informing the center control device 200 of the single item transaction (step 315). The single item details message is created in a format as shown in FIG. 4(A). In other words, the "item length" is the beginning of the single item detail message.

"Item identification code" that indicates the type of received message.

“Department code” and “Product quantity” representing the department of the transaction
, ``transaction amount j,'' the ``scan code (product code)'' obtained by reading, and ``item separator'' indicating the end of the individual item details message.

Here, the terminal control unit 221 records the products corresponding to the created individual item statement message in the customer's sales, and if the transaction involves only the products, press the total key (included on the keyboard 253) to display the subtotal.

A total process is performed (step 316). In that case, a receipt (not shown) printed by printer 257 is issued to the customer, and the received money is stored in safe 259. However, if transactions for other products continue, total processing will not be performed.
Move on to the next transaction.

By performing these steps, the single item transaction is completed and the next transaction is started.

When the transaction for a single item is completed, the single item details message edited in the format described above is sent to the PO8 terminal device 2.
The data is transmitted from the terminal control unit 221 of 50 to the center control device 200 via the local line 241. The store controller 213 of the center control device 200 analyzes this single item detail message, recognizes that the item has been sold, and reports the sales at the sent PO8 terminal device 250 or the retail store where this POS system is installed. Total sales.

If a customer brings not just one product but multiple products,
The above-described procedure is also executed for the next product to perform the next transaction.

The above is the operation when the product code has already been registered in the terminal storage section 215 of the PO3 terminal device 250.

(iii) At the end of PO3F' 3. For example, a case will be described in which a product has just arrived and has not yet been registered in the terminal storage unit 215 of the POS terminal device 250.

If a customer brings such unregistered products, P.
Since the read code obtained by scanning with the barcode scanner 217 of the O3 terminal device 250 does not exist in the terminal storage section 215, the search by the terminal control section 221 is not performed normally. Therefore, in the execution order shown in FIG. 3, a negative determination is made in step 313.

When the terminal control unit 221 determines that the corresponding product code does not exist in the terminal storage unit 215 (it is unregistered), the terminal control unit 2
21 issues a message meaning rPLU absent j. For example, the alarm device generates an alarm sound, or the display unit 255 displays the message "No PLU j" (step 317). Such an alarm sound or message allows the cashier operator to confirm that the current target product is on the terminal. It is learned that it is not registered in the storage unit 215.

The generation of the alarm sound and the message ``No rPLU J'' continue until the operator operates the clear key (not shown) provided on the keyboard 253 (step 318).

In response to the operation of the clear key, the terminal control unit 221 of the PoS terminal device 250 generates an alarm sound.

The message "No rPLtJ" is canceled (step 319). Subsequently, the terminal control unit 221 edits the individual item details message with an identification code indicating that the product is unregistered (step 320).

This single item detail message has a format as shown in Figure 4 (B).
In addition to the "product code") and the "item break" indicating the end of the individual item description message, the "item identification" is an indicator code (for example, setting a specific flag) indicating that the product is unregistered.

The single item details message including the "item identification" added in this way is transmitted from the PoS terminal device 250 to the center control device 200 side, and one transaction is completed. On the center control device 200 side that receives this single item detail message, the store controller 213 determines whether to perform aggregation operations according to the product reading on the PoS terminal or whether or not the product is not registered in the PoS terminal. to do.

(iv) Solution at the Center Control Device] Operation As described above, the single item detail message transmitted from the PO3 terminal device 250 to the center control device 200 side via the private line 241 is sent to the center control device 200. The store controller 213 analyzes the information.

FIG. 5 shows the order in which the store controller 213 of the center control device 200 analyzes the received single item detail message and registers the product. Reference will now be made to FIGS. 2, 4 and 5.

(iv-1) The tree raising center control device 200 of i receives the message regarding one transaction received from the PoS terminal device 250 (Step 5
11). The store controller 213 extracts the single item detail message by detecting the "item length" (step 512).

Following this "Item Length", "Item Identification" is detected, and in the received single item details message, r indicates that the code of the product of the transaction is unregistered on the PoS terminal device 250 side.
Determine whether or not there is an unregistered sign j (in the example shown in Fig. 4, "item identification" is flagged) (
Step 513).

If r unregistered sign j does not exist in "item identification" (negative determination), the product for one transaction represented by the single item detail message has already been registered in the terminal storage unit 215 of the PO3 terminal device 250. That's what happened. Therefore,
On the center control device 200 side, the single item is recorded in sales data (step 514). Next, the center control device 200 determines whether processing for all single item detail messages has been completed (step 515).
. If a single item details message for another transaction is to be received, a negative determination is made, and the process returns to step 512 to repeat the above execution operation.

When all the processing for the detailed message regarding the single item transaction is completed (affirmative determination in step 515), the PoS terminal device 2
It is determined whether it is necessary to newly register a product on the 50 side (step 516). In this case, since there is no new registration on the PoS terminal device 250 side (negative determination), the execution operation as the store controller 213 ends.

(iv-2) New record of product r By the way, the single item detail message sent from the PO3 terminal device 250 side to the center control device 200 side is not necessarily related to sales transactions, but is for unregistered products at the PoS terminal. It may also be a telegram notifying you of this. In this case, it is necessary to newly register the product.

In the case of such registration, the single item detail message received by the center control device 200 includes an "unregistered sign j (flag) indicating that it is unregistered" in the "item identification j" next to the "item length". standing).This results in
The product code for the transaction indicated in the received single item detail message is P.
On the O8 terminal device 250 side, it is displayed that it is unregistered.

Therefore, in the above-described execution order, a negative determination is made in step 513, and the store controller 213 of the center control device Z200 detects the "scan code (product code)" in the single item detail message. Based on the code corresponding to this product code, the main storage unit 211 inside the center control device 200 is searched (Step 517), and it is determined whether or not the code corresponding to the product code is registered in the main storage unit 211. (step 518).

If it has already been registered in the main storage unit 211 (affirmative determination),
The store controller 213 retrieves the registered product code from the main storage section 211 and temporarily stores it in the secondary storage section 231 (step 519). Here, the code to be read is the product name 1 necessary for aggregation, accounting, management, etc. of the product.
Information codes such as prices are extracted all at once.

After reading out the unregistered product code in this way,
The center control device 200 performs the same operation as described above.
Then, it is determined whether processing for all single item detail messages has been completed (step 515). If a single item details message for another transaction is to be received, a negative determination is made, and the process returns to step 512 to repeat the above execution operation. When the processing for all detailed messages is completed (affirmative determination in step 515), it is determined whether or not it is necessary to newly register the product on the PO8 terminal device 250 side (step 516).
). In the case of ε, since there is a new registration on the POS terminal device 250 side (affirmative determination), the store controller 213 of the center control device 200 reads the unregistered product code temporarily stored in the secondary storage unit 231 and sends it to the local circuit ' fa241
is sent to the PO8 terminal device 250 side via
0).

The terminal control unit 221 of the POS terminal device 250 temporarily stores the received unregistered product code in the secondary storage unit 251, and then searches the terminal storage unit 215 for an appropriate time (for example, searching the terminal storage unit 215) for the operation of the POS terminal device 250. 2), the data is written from the secondary storage section 251 to the terminal storage section 215 to newly register it.

In this way, the terminal storage section 2 of the PO8 terminal device 250
15, the previously unregistered product code has been newly registered. After that, even if the customer brings the product, the POS terminal device 250 uses the barcode scanner 21.
A normal transaction read by 7 can be carried out.

(iv-3) Unregistered product on the center control device side 1 coin Also, there are cases where an unregistered product at the end of the posg, for example, has just arrived and is not registered on the center control bag W2O0 side. In this case, first, the center control device 20
It is necessary to newly register the product on the 0 side, and then register it on the PO8 terminal device 250 side.

In the case of such registration, the center control device 200 receives the "Item Identification" in the single item details message.
After detecting the "unregistered sign j" indicating that the product is unregistered on the POS terminal device 250 side, the store controller 213 searches the main storage section 211, and the product that is unregistered in the terminal storage section 215 is stored in the main storage section 211. However, since it is unregistered, in the above-described execution order, a negative determination is made in step 518.

In response to such a negative determination, the store controller 213 causes the display unit 235 to display that the item in the transaction based on the received single item statement message is “not registered in the main storage unit 211,” and also causes the printer 237 to display the transaction information in the received single item statement message. The products are “
” is printed in the main storage unit 211 (step 521).

At that time, the read product code obtained by analyzing the received single item detail message is also shown. After that, the store controller 21
The execution of step 3 moves to step 515.

Through such display and printout, the operator on the center control device 200 side knows that there are unregistered products in both the terminal storage unit 215 and the main storage unit 211, and which products are unregistered. . Then, the operator operates the keyboard 233 for the indicated product and inputs the product code with information such as the product name and price.

The input product code is stored in the secondary storage section 231 by the store controller 213, and is also stored in the main storage section 21.
1 to register a new one. Further, the store controller 213 reads the information from the secondary storage unit 231 and transmits it to the pos@terminal N250 side via the premises map &'1241. On the PoS terminal device 250 side, the terminal control unit 221
is newly registered in the terminal storage unit 215 in the same manner as in the case of new registration described in "New Registration of r(iv-2) Product" described above (step 520).

In this way, the terminal storage section 2 of the PoS terminal device 250
15, the previously unregistered product code has been newly registered. After that, even if the customer brings the product, the PoS terminal device 250 uses the barcode scanner 21.
7 allows normal transactions to be read.

■Summary of 1 In this way, the terminal storage section 2 of the PoS terminal device 250
Even if the product is not registered in 15, the center control device 200 side is notified of this fact, and the PO3 terminal device 250 side obtains the unregistered product code from the center control device 200 side and registers it newly. It is supposed to be done. Therefore, even if a product was previously unregistered, after it has been newly registered, the barcode scanner 217 reads the code of the product, and normal accounting and tabulation processing becomes possible. that time,
There is no need for manual input using the keyboard 253 of the PoS terminal device 250, so the original functions of the POS system can be smoothly performed.

V, H's...) and Mu.

In addition, in the embodiment of the present invention described above, a case has been described in which the center control device 200 and the PoS terminal device 250 are installed in the same premises, but the present invention is not limited to this. For example, in a large-scale retail business, the installation location of the center control device 200 and the installation location of each POS terminal device 250 may be separated, and they may be connected by a public telephone line instead of the private line 241. Even in that case, the exchange of unregistered product codes between the PoS terminal device 250 and the center control device 200 is done automatically, so a telephone call is made each time an unregistered product code occurs. No more hassle.

In addition, in the embodiment of the present invention described above, the fact that the product is unregistered is indicated by the "unregistered sign j" of "item identification", but other means may be used. Any method that can notify the center control device 200 that the product code is unregistered for the PoS terminal device 250 may be used.

The main storage unit 211 and the secondary storage unit 231 of the center control device 200, and the terminal storage unit 215 and the secondary storage unit 251 of the PoS terminal device 250 may not be separate, but may be the same storage medium.

In the POS system of the above embodiment, the code attached to the product to be read is the so-called J code starting with "49".
In addition to the AN code, a standardized PLU code may also be used. It goes without saying that the present invention can also be applied to so-called NON PLU codes.

Furthermore, in "■, Correspondence between Examples and FIG. 1",
Although the correspondence between FIG. 1 and the present invention has been described, those skilled in the art will easily imagine that the present invention is not limited to this and that there are various modifications.

〔Effect of the invention〕

As described above, according to the present invention, when the center side refers to the terminal registration means in which a plurality of product codes registered in the terminal registration means are registered and performs accounting processing etc. according to the reading code of the target product, If the device is not registered in the device registration device, it will be notified to that effect, and the unregistered code will be obtained from the center and registered in the device registration device, which will enable the next target product to be read, thereby making the POS system smoother. This is extremely useful from a practical point of view, as it allows for efficient operation.
