Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] In a registered product code update control method, a code for a plurality of products registered in advance in a main registration means is obtained by the main control means and output to the terminal control means. It is registered in the registration means, and the reading code obtained by the reading means reading the code attached to the product to be read is searched for whether it is already registered in the terminal registration means. If not, the main control is performed. By notifying the means to that effect, obtaining the registration code which does not exist from the main registration means and registering it in the terminal registration means, it is possible to read the next target product. In addition, a search is made as to whether or not an unregistered code to the terminal registration means is registered in the main registration means, and if it is not registered in the main control means, an unregistered notification signal is output, and main registration is performed by the input registration signal. Since it can be newly registered in the means and can also be registered in the terminal registration means, it becomes possible to read the merchandise which was not previously registered in the terminal registration means.

[Industrial applications]

The present invention relates to a POS system for updating and controlling registered merchandise information. For example, a POS system for smoothly updating a merchandise code when registering a merchandise code in a POS terminal device installed at a cash register such as a supermarket or a retail store. It is about.

At these cash registers, smooth check-out is especially required for sellers and buyers.

[Conventional technology]

2. Description of the Related Art Conventionally, in a POS system generally used in the retail industry or the like, a plurality of product codes are registered in advance in a main registration means provided at a distant place or a center side of a premises. A POS terminal is installed in a cash register that actually sells products, and the POS terminal device includes a terminal registration unit. Usually, the storage capacity of the terminal registration means is smaller than that of the main registration means.

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

At the cash register where the customer brought the product, the code attached to the product to be read (for example, JAN
Code) is read by a reading means such as a bar code reader using a laser scanner. The code read is
A code group stored in the terminal registration means is searched to obtain the price, information for each type of the product, the cashier is notified of the selling price, and the center side manages the sold product. To transmit information for.

As a result, it becomes possible to sell the product brought by the customer, and the seller side can obtain various information about the sold product, so that the totaling and product management can be efficiently performed.

[Problems to be solved by the invention]

By the way, in the above-mentioned conventional method, for all the products lined up at the retail store where the terminal control means is installed, the product code is transferred from the main registration means on the center side to the terminal registration means of the POS terminal device on the cash register side. It is assumed that you have been registered.

However, the product code may not be registered from the center side to the POS terminal side with respect to the terminal registration means on the POS terminal side of the retail store in which the terminal control means is installed. For example, when a new product arrives at a retail store, code registration from the center side may be delayed. Also, for products that are sold only in a certain season, the registered products in the terminal registration means of the POS terminal device will be deleted, and the product registration will be updated for the products of the next season. If the customer brought
Even if it was read by the reading means, the code could not be registered in the terminal registration means, so automatic accounting could not be performed.

When such automatic checkout is not possible, the cashier operator inputs the price from the keyboard provided in the POS terminal and performs the slip processing and the collection processing. Also, because the same situation occurs for the same product, the cashier once suspends his work and immediately goes to the center side.
I was informed that the product was not registered. Upon receipt of the notification, the operator on the center side operates the main control means to send the unregistered product code from the main registration means to the terminal registration means on the POS terminal side so as to register it in the terminal registration means. As a result, even if the next customer brings the same product, the reading process can be automatically read by the reading unit to perform the sales process.

However, until the product code is registered in the terminal registration means on the POS terminal side, as long as the customer brings the product, the cashier operator must constantly enter the key, and due to business suspension, etc. For this reason, there was a problem that the efficiency of sales processing was extremely poor.

In addition, regarding the reading error due to non-registration in the terminal registration means, it is necessary for the cashier to contact the center side,
There has been a problem that the cashier operator has a heavy burden. Such a problem is that if the point of sale where the POS terminal is installed and the place where the main control means on the center side is installed are close to each other, it is easy to notify such unregistered information. However, if the store where the POS terminal is installed is far from the center, notification by phone call or the like is required, and there is a problem that the office efficiency is extremely poor.

The present invention was created in view of these points, and from the viewpoint of streamlining product sales office work, which is an advantage in originally installing a POS system, the present invention is used as a terminal registration means on the POS terminal side. The objective is to provide a POS system that enables efficient management of POS terminal cash registers and rational management of products for sale even if is not registered.

[Means for solving problems]

 FIG. 1 is a configuration block diagram of the present invention.

In the figure, the main registration means 111 can register product codes for a plurality of products.

The main control means 113 receives the input registration signal 112, controls the registration of the product code input to be registered in the main registration means 111 in the main registration means 111, and requires the registered product code of the main registration means 111. Can be obtained and output according to.

The terminal registration means 115 can store the product code.

The reading means 117 reads the code attached to the product to be read.

The terminal control means 121 receives the registered merchandise code output from the main registration means 111 in response to the main control means 113 and stores it in the terminal registration means 115, and also corresponds to the read code obtained by the reading means 117. Whether or not the product code exists in the terminal registration means 115 is searched, and if it exists, a read compatibility signal 119 applicable to the transaction is output, and if it does not exist, the main control means 113 is notified.

When the terminal control means 121 notifies the main control means 113 that the code corresponding to the read code does not exist in the terminal registration means 115, the main control means 113 determines that the registration code that does not exist in the terminal registration means 115. The main registration means 111 is searched to see if it is registered, and if it is registered in the main registration means 111, the registration code is obtained from the main registration means 111 and sent to the terminal control means 121. Registration method
It is designed to be registered in 115 and the main registration means 111
If not registered, the unregistered notification signal 123 is output.

Therefore, as a whole, if the code corresponding to the read code is not registered in the terminal registration means 115 and the main registration means 111, the unregistered notification signal 123 is prompted to input the product code.

[Action]

In FIG. 1, a plurality of product codes input on the basis of the input registration signal 112 are registered in the main registration means 111, and these product codes are taken out by the control of the main control means 113, and are sent to the terminal control means 121. It is supplied to the terminal registration means 115 and stored and registered in the terminal registration means 115.

When the merchandise code to be sold is read by the reading means 117, the merchandise code information is read by the terminal control means 12
Supplied to 1. The terminal control means 121 searches the terminal registration means 115 for a code corresponding to the read code.

If a code corresponding to the read code is present in the terminal registration means 115 as a result of the search by the terminal control means 121, a read compatibility signal 119 is output and a predetermined process for the product is performed. If the code corresponding to the read code does not exist in the terminal registration means 115, the terminal control means 121 notifies the main control means 113 that there is no such product code.

Upon receiving this notification, the main control means 113 receives the notification, and the terminal registration means 1
The unregistered code to 15 is searched for whether it is registered in the main registration means 111, and if the code exists in the main registration means 111, the main control means 113 sends the product code from the main registration means 111. Obtained and sent to the terminal control means 121, the terminal control means 12
1 registers in the terminal registration means 115.

If the code does not exist in the main registration means 111, the main control means 113 outputs the unregistered notification signal 123. In response to the unregistered notification signal 123, the product registration code is newly registered in the main registration means 111 by the input registration signal 112. After that, since it is already registered in the main registration means 111, the main registration means 1
If the product code exists in 11, the operation is similar.

According to the present invention, in the POS system in which the registered product code of the main registration means 111 is registered in the main control means 113 and the terminal registration means 115 is searched by the reading of the reading means 117 for sale, the terminal registration means 115 When the reading means 117 reads a merchandise not registered in, the merchandise code is obtained from the main registration means 111 and registered in the terminal registration means 115. Further, even if there is no registration in the main registration means 111, it will prompt the new registration of the product, and if such new registration is made, thereafter, the code is similarly registered in the terminal registration means 115. . Therefore, it becomes possible to read the products that have not been previously registered in the terminal registration unit 115.

5 shows the order of processing of the store controller 213 in the center control device 200 when exchanging information with the 200 side. Below, the second
Please refer to FIGS.

(I) Product code registration to the POS terminal The operator uses the keyboard 233 of the center control unit 200.
Is operated to input the product code of a product that has arrived at the retail store and should be displayed at the store. The entered product code is registered in the main storage unit 211 by the store controller 213. In this way, the product code of the product handled at this retail store is registered when the product arrives. The operator operates the keyboard 233 each time to cancel the registration of a product that is no longer handled.

With respect to the products normally sold at this store, the operator operates the keyboard 233 from the center control device 200 side to start the product code registered to the POS terminal device 250 managed by the center control device 200. To do. In response to this, the store controller 213 extracts a plurality of product codes registered in the main storage unit 211,
It is transmitted to the POS terminal device 250 via the local line 241.

On the POS terminal device 250 side, the terminal control unit 221 receives the plurality of product codes received from the center control device 200 side, supplies them to the terminal storage unit 215, and registers them. This makes this P
At the cash register in which the OS terminal device 250 is installed, it is possible to sell products and perform accounting processing.

(Ii) Product Reading by POS Terminal As described above, the business of reading, selling, and accounting for a product brought by a purchasing customer by the POS terminal device 250 in which the product code is registered will be described.

When the customer brings the products lined up in the store to the cashier, the cashier operator scans with the barcode scanner 217,
A code (for example, a JAN code) attached to the product to be read is read (step 311). Hereinafter, this code is a PLU code.

The terminal control unit 221 supplied with the read code by the barcode scanner 217 searches the terminal storage unit 215 for the registration code corresponding to the read code in order to refer to the selling price and the product name of the product (step 312). . That is, the terminal control unit 221 determines whether the 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 the product name of the product are extracted from the corresponding code. Further, the terminal control unit 221 displays the extracted product price on the display unit 255 and prints the product price and the product name of the product by the printer 257 (step 314).

In this way, when the transaction of one product is completed, the terminal control unit
221 edits a message notifying the center control device 200 side of the single item transaction (step 315). The single item statement is
It is created in the format as shown in FIG.
In other words, the "item length" that is the beginning of the single item description message, the "item identification code" that indicates the type of the received message,
It consists of the "department code" that represents the department of the transaction, the "quantity of the product", the "transaction amount", the "scan code (product code)" obtained by reading, and the "item delimiter" that represents the end of the individual item statement message. There is.

Here, the terminal control unit 221 counts the product corresponding to the created single-item statement message as the customer's sales, and if the transaction is only for the product, press the total key (included on the keyboard 253) to display the subtotal, Perform total processing (step
316). In that case, a receipt (not shown) printed by the printer 257 is delivered to the customer, and the received money is stored in the safe 259. However, if the transaction of another product is continued, the total transaction is not performed and the next transaction is performed. By carrying out such a procedure, the transaction of a single item is completed and the next transaction is started.

When the transaction for a single item is completed, the single item statement message edited in the above format will be sent to the POS terminal device 250.
Is transmitted from the terminal control unit 221 to the center control device 200 via the private line 241. The store controller 213 of the center control device 200 analyzes this single item statement message, recognizes that the item has been sold, and sends it to the POS terminal device 2
Aggregate sales at 50 or sales at all retail stores where this POS system is installed.

If the customer carries not only one product but a plurality of products, the above procedure is executed for the next product and the next transaction is performed.

The above is the operation when the product code is already registered in the terminal storage unit 215 of the POS terminal device 250.

(Iii) When Not Registered in POS Terminal For example, a case where a product is just received and the product is not yet registered in the terminal storage unit 215 of the POS terminal device 250 will be described.

If a customer brings such an unregistered product,
Since the read code obtained by scanning with the barcode scanner 217 of the POS terminal device 250 does not exist in the terminal storage unit 215, the search by the terminal control unit 221 is not normally performed. 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 (unregistered), the terminal control unit 221 issues a message meaning “no PLU”. For example, an alarm sound is generated by an alarm device, or a message "No PLU" is displayed on the display unit 255 (step 31).
7). From such an alarm sound and a message, the cashier operator knows that the current target product is not registered in the terminal storage unit 215.

The occurrence of such an alarm sound and the message "no PLU" continue until the operator operates a clear key (not shown) provided on the keyboard 253 (step 31).
8).

In response to the operation of the clear key, the terminal control unit 221 of the POS terminal device 250 cancels the alarm sound and the message "no PLU" (step 319). Then, the terminal control unit 2
21 edits the single-item statement electronic message to which an identification code indicating that the product is not registered is added (step 320).

This single item description message has a format as shown in FIG. 4 (B), and the "item length" which is the beginning of the single item specification message, the "scan code (product code)" obtained by reading, and the single item specification message In addition to the "item delimiter" indicating the end, "item identification" is a sign code (for example, a specific flag is set) indicating that the product is not registered.

The single item statement including the “item identification” added in this way is sent from the POS terminal device 250 to the center control device 200.
It is transmitted to the side and ends one transaction. On the side of the center control device 200 that has received this single item statement, the store controller 213 performs a totaling operation according to the product reading at the POS terminal or determines whether the product is not registered at the POS terminal. To do.

(Iv) Analysis operation on the side of the center control device As described above, the POS terminal device 250 to the premises line 24
The store controller 213 of the center control device 200 analyzes the single-item specification message transmitted to the center control device 200 side via 1.

FIG. 5 shows an order in which the store controller 213 of the center control unit 200 analyzes the single item specification message and registers the item. Below, FIG. 2, FIG. 4 and FIG.
Refer to the figure.

(Iv-1) Ordinary Sales Processing The center control device 200 receives a message for one transaction received from the POS terminal device 250 (step 511).
The store controller 213 extracts the single item statement by detecting the "item length" (step 51).
2).

The "item identification" following this "item length" is detected, and in the received single item statement message, the "unregistered signature" (4th item) indicating that the product code of the transaction is not registered on the POS terminal 250 side. In the example shown in the figure, it is determined whether or not there is a flag in "item identification" (step 513).

If "unregistered signature" does not exist in "item identification" (negative determination), it is represented by the individual item statement message 1
The product for the transaction has already been registered in the terminal storage unit 215 of the POS terminal device 250. Therefore, on the side of the center control device 200, the single item is added to the sales data (step 514). Then, this center control device 2
At 00, it is determined whether or not the processing for all individual item statement messages has been completed (step 515). If a single-item statement message for another transaction should be received, a negative determination is made, and the processing returns to step 512 and the above-described operation is repeated.

When all the processing for the detailed message regarding the single item transaction is completed (affirmative determination in step 515), it is determined whether or not a new product needs to be registered in the POS terminal 250 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 registration of product By the way, from the POS terminal device 250 side to the center control device 20
The single item statement message sent to the 0 side is not necessarily related to sales transactions, but may be a message notifying that it is an unregistered item at the POS terminal. In this case, it is necessary to newly register the product.

In the case of such registration, the single item specification message received by the center control device 200 includes an “unregistered signature” (flag is unregistered) in the “item identification” next to the “item length”. Standing). As a result, the product code of the transaction shown in the received single item statement message is POS.
On the terminal device 250 side, it is indicated that the terminal device 250 has not been registered. Therefore, in the execution order described above, an affirmative determination is made in step 513, and the store controller 213 of the center control device 200 detects the “scan code (product code)” in the single item statement 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 the code corresponding to the product code is registered in the main storage unit 211 (step 518).

If it is already registered in the main memory 211 (affirmative determination),
The store controller 213 retrieves the registered product code from the main storage unit 211 and temporarily stores it in the sub storage unit 231 (step 519). Here, as the codes to be read, information codes such as product names and prices necessary for totaling, accounting, management, etc. of the products are collectively extracted.

In this way, after the unregistered product code is read out, the center control device 20
At 0, it is determined whether or not the processing has been completed for all single item statement messages (step 515). If a single-item statement message for another transaction should be received, a negative determination is made, and the processing returns to step 512 and the above-described operation is repeated. When the processing has been completed for all the statement messages (affirmative determination in step 515), it is determined whether or not a new product needs to be registered in the POS terminal device 250 side (step 516). In this case, since there is 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 once stored in the secondary storage unit 231 and sets the private line 241. It is sent to the POS terminal device 250 side via (step 520). The terminal control unit 221 of the POS terminal device 250,
The received unregistered product code is temporarily stored in the secondary storage unit 251, and the secondary storage unit 2 is stored at an appropriate time during the operation of the POS terminal device 250 (for example, when the terminal storage unit 215 is not searched).
Write from 51 to the terminal storage unit 215 and newly register.

In this way, the previously unregistered product code is newly registered in the terminal storage unit 215 of the POS terminal device 250. After that, even if the customer brings the product,
In the POS terminal device 250, normal transactions read by the barcode scan 217 can be performed.

(Iv-3) In the case where the center control device side is not registered By the way, an unregistered product in the POS terminal may be unregistered even in the center control device 200 side immediately after arrival, for example. In this case, first, it is necessary to newly register the product on the side of the center control device 200, and thereafter, it is registered on the side of the POS terminal device 250.

In the case of such registration, by the "item identification" in the single item statement message received by the center control device 200,
"Unregistered sign" indicating that the POS terminal 250 is not registered
Main memory 2 by the store controller 213 after detecting
Depending on the search of 11, the unregistered product in the terminal storage unit 215 is also unregistered in the main storage unit 211, so in the execution order described above, a negative determination is made in step 518.

According to such a negative determination, the store controller 213
Displays, on the display unit 235, that the product for the transaction by the received single item statement electronic message is “not registered in the main storage unit 211”, and the printer 237 displays the product for the transaction “Not registered in the main storage unit 211. Is printed (step 52)
1). At that time, the read product code obtained by the analysis of the received single product statement message is also shown. Then, the execution of the store controller 213 shifts to step 515.

By such a display and printout, the operator on the side of the center control device 200 can make the terminal storage unit 215 and the main storage unit
Know that there are unregistered products on both sides of 211 and which products are unregistered. Therefore, the operator operates the keyboard 233 for the displayed product to display the product name,
Enter the product code with information such as price. The input product code is stored in the secondary storage unit 231 by the store controller 213, and is written in the main storage unit 211 to be newly registered. Further, the store controller 213 reads out from the secondary storage unit 231, and transmits it to the POS terminal device 250 side via the private line 241. On the POS terminal device 250 side, the terminal control unit 221 performs the above-mentioned “(iv-2) New registration of product”.
In the same manner as in the case of the new registration described above, the terminal storage unit 215
New registration to (step 520).

In this way, the previously unregistered product code is newly registered in the terminal storage unit 215 of the POS terminal device 250. After that, even if the customer brings the product,
With the POS terminal device 250, normal transactions read by the barcode scanner 217 are possible.

IV. Summary of Examples In this way, even for a product that has not been registered in the terminal storage unit 215 of the POS terminal device 250, the fact is notified to the center control device 200 side, and the POS terminal device 250 side The unregistered product code is obtained from the center control device 200 side and newly registered. Therefore, even if the product has not been registered before, after the new registration, the code of the product can be read by the barcode scanner 217, and normal accounting and totaling processing can be performed. At that time, since it is not necessary to manually input by the keyboard 253 of the POS terminal device 250, the original function of the POS system can be smoothly exhibited.

V. Modified Embodiment of the Invention In the above-described embodiment of the present invention, the case where the center control device 200 and the POS terminal device 250 are installed in the same premises has been described, but the present invention is not limited to this. . For example, as 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 from each other, and they may be connected by a public telephone line instead of the private line 241. Even in that case, since the unregistered product code is automatically exchanged between the POS terminal device 250 and the center control device 200, it is troublesome to make a telephone call each time an unregistered product code is generated. Run out.

Further, in the above-described embodiment of the present invention, the fact that the product is unregistered is indicated by the "unregistered signature" of "item identification", but other means may be used. In short, any method can be used as long as it can notify the center control device 200 that the product code is an unregistered product code of the POS terminal device 250.

The main storage unit 211 and the sub storage unit 23 of the center control device 200
