Description

Embodiments of the present invention relate to article information readers and programs.

Conventionally, a symbol such as a barcode attached to a product or the like is read by a barcode reader or the like to acquire a product code that identifies the product with the symbol, and sales registration of the product is performed based on the acquired product code. There is an article information reading device such as a POS (Point of Sales) terminal that executes processing.

Recently, there is a POS terminal having a function of attaching a wireless tag instead of a symbol to a product, reading the tag information transmitted by the wireless tag by a tag reader, and executing a sales registration process. And recently, products with only symbols and products with both symbols and wireless tags may be sold together, so POS terminals are bar code readers so that they can read both. And equipped with a tag reader.

The customer or the clerk takes out the product from the basket and makes the symbol read. The barcode reader then reads the symbol. In addition, the tag reader reads the tag information by performing an operation to read the symbol.

By the way, when both the wireless tag and the symbol attached to the product are read, the POS terminal performs the sales registration process based on the tag information read from the wireless tag and the sales registration based on the read symbol for one product. There is a risk of so-called double registration, in which both processing is performed, as if sales registration processing was performed for two products.

An object to be solved by the present invention is to provide an article information reading device and a program that do not perform double registration even if both a wireless tag and a symbol are read.

The article information reading device of the embodiment is a first storage that stores the number of acquisitions of the article-specific information for each article-specific information acquired based on the tag information stored in the radio tag attached to the article received by the antenna. The unit, the second storage unit that stores the acquisition number of the article specific information for each article specific information acquired by reading the symbol attached to the article, and the acquisition that the first storage unit stores for the same type of article. A determination unit that determines the number and the magnitude of the acquisition number stored by the second storage unit, and a processing unit that executes processing based on the article identification information associated with the acquisition number determined by the determination unit to be large. , Equipped with.

The self-POS terminal 1 executes the sales registration process based on the sales registration operation performed by the customer. Further, the self-POS terminal 1 executes the payment process based on the payment operation performed by the customer.

Here, the sales registration process is the product from the product master 142 (see FIG. 2) based on the product code (article identification information) that specifies the type of the product included in the tag information read by the self-POS terminal 1. Product information (product name, price, etc.) is read, the read product information of the product is displayed, and the product information is stored in the product information unit 131 (see FIG. 2). The settlement process is to display the total amount and tax amount related to the transaction based on the product information stored in the product information unit 131 along with the sales registration process, and to calculate and display the change based on the deposit received from the customer. Processing, processing to issue a receipt printed with product information and payment information (total amount, deposit amount, change amount, etc.). Information that combines product information and payment information is called sales information.

Here, the product code will be described. The product code is information that identifies the type of product. For example, the product code is information that identifies XX milk. The product code is not information that individually identifies each individual item of XX milk. Information that individually identifies products of the same type is an individual product code (individual product identification information). It is the product code that the self-POS terminal 1 reads and acquires the symbol. The tag information transmitted from the wireless tag includes an individual product code that identifies the product as an individual product. The self-POS terminal 1 acquires the product code of the product based on the read individual product code.

Further, the control unit 100 is connected to the communication interface (I / F) 32 via the bus 15. The communication interface 32 is connected to a store server (not shown), which is a higher-level device of the self-POS terminal 1, so that information can be transmitted and received.

Next, the tag information unit 132 will be described. The tag information unit 132 stores a product code that identifies a product acquired based on the tag information received by the antenna 27, and the number of acquisitions that is the number of times the product code is acquired. FIG. 3 is a diagram showing an example of the memory configuration of the tag information unit 132. As shown in FIG. 3, the tag information unit 132 includes a product code unit 1321 and an acquisition number unit 1322. The tag information unit 132 stores the product code acquired for the first time in the product code unit 1321. Further, the tag information unit 132 stores the acquired number “1” in the acquired number unit 1322 for the product code acquired for the first time. Further, when the acquired product code is already stored in the product code unit 1321, the tag information unit 132 counts up the acquired number stored in the acquired number unit 1322 by +1 and stores the product code. To do.

In the example of FIG. 3, the number of acquisitions of the product code “4900001” stored in the product code unit 1321 is “5”. This indicates that the product code "4900001" has been acquired five times based on the read tag information. Further, regarding the product code "4900002", the number of acquisitions is "2", which indicates that the product code "4900002" has been acquired twice based on the read tag information. Further, regarding the product code "4900003", the number of acquisitions is "1", which indicates that the product code "4900003" has been acquired once based on the read tag information.

Next, the barcode information unit 133 will be described. The bar code information unit 133 stores the product code acquired by reading the symbol and the number of acquired product codes. FIG. 4 is a diagram showing an example of the memory configuration of the barcode information unit 133. As shown in FIG. 4, the barcode information unit 133 includes a product code unit 1331 and an acquisition number unit 1332. The bar code information unit 133 stores the product code acquired for the first time in the product code unit 1331. Further, the barcode information unit 133 stores the acquired number "1" in the acquired number unit 1332 for the product code acquired for the first time. Further, when the acquired product code is already stored in the product code unit 1331, the barcode information unit 133 counts up the number of acquisitions stored in the acquisition number unit 1332 by +1 for the product code. Remember.

In the example of FIG. 4, the number of acquisitions of the product code “4900001” stored in the product code unit 1331 is “4”. This indicates that the product code "4900001" has been acquired four times based on the read symbol. Further, regarding the product code "4900002", the number of acquisitions is "2", which indicates that the product code "4900002" has been acquired twice based on the read symbol. Further, regarding the product code "4900004", the number of acquisitions is "1", which indicates that the product code "4900004" has been acquired once based on the read symbol.

Here, comparing the product code stored in the tag information unit 132 with the product code stored in the barcode information unit 133, the product code "4900001" is obtained by the tag information unit 132. The number of acquisitions "5" is stored in, and the number of acquisitions "4" is stored in the number of acquisitions 1332 of the barcode information unit 133. This is because when the customer passes the product related to the product code "4900001" five times in front of the barcode reader 33, the tag reader 30 reads the tag information related to the product code "4900001" five times and the barcode reader 33. Indicates that the symbol relating to the product code "4900001" has been read four times. That is, the tag reader 30 has read all the tag information from the wireless tag attached to the product that has passed five times. In addition, the barcode reader 33 read the symbol attached to the product that passed five times four times (it could not be read once). The reason why it could not be read once is, for example, that the symbol attached to the passed product did not face the barcode reader 33 side, or the symbol was dirty and could not be read by the barcode reader 33, etc. Is.

Further, regarding the product code "4900002", the acquisition number "2" is stored in the acquisition number unit 1322 of the tag information unit 132, and the acquisition number "2" is also stored in the acquisition number unit 1332 of the barcode information unit 133. There is. This is because when the customer passes the product related to the product code "4900002" twice in front of the barcode reader 33, the tag reader 30 reads the tag information related to the product code "4900002" twice and the barcode reader 33. Indicates that the symbol relating to the product code "4900002" has been read twice. That is, the tag reader 30 reads the tag information twice from the wireless tag attached to the product that has passed twice. In addition, the barcode reader 33 read the symbol attached to the product that passed twice.

Regarding the product code "4900003", the tag reader 30 also reads the tag information once from the wireless tag attached to the product that has passed once. In addition, the barcode reader 33 reads the symbol attached to the product that has passed once.

Regarding the product code "4900004", the acquisition number "1" is stored in the acquisition number unit 1332 of the barcode information unit 133. However, the tag information unit 132 does not store the product code and the number of acquisitions. This is because the product specified by the product code "4900004" has a symbol but no wireless tag. Therefore, when the product was passed, the barcode reader 33 read the symbol, but the tag reader 30 could not read the tag information.

Next, the product information unit 131 will be described. The product information unit 131 stores product information (product name, product price, etc.) of the product for which the self-POS terminal 1 has performed sales registration processing. The product information unit 131 is created based on the product code and the number of acquisitions stored in the tag information unit 132 and the barcode information unit 133. FIG. 5 is a diagram showing an example of the memory configuration of the product information unit 131. The product information unit 131 includes a product code unit 1311 and an acquisition number unit 1312.

For the product according to the product code "4900001", the acquisition number "5" is stored in the acquisition number part 1322, and the acquisition number "4" is stored in the acquisition number part 1332. Therefore, the product code "4900001" is stored in the product code unit 1311 of the product information unit 131. Further, the acquired number "5" is stored in the acquired number unit 1312. This is because the acquisition number "5" stored in the acquisition number unit 1322 is larger than the acquisition number "4" stored in the acquisition number unit 1332.

Further, for the product related to the product code "4900002", the acquisition number "2" is stored in the acquisition number unit 1322, and the acquisition number "2" is stored in the acquisition number unit 1332. Therefore, the product code "4900002" is stored in the product code unit 1311 of the product information unit 131. Further, the acquired number "2" is stored in the acquired number unit 1312.

Similarly, for the product related to the product code "4900003", the product code "4900003" is stored in the product code unit 1311 of the product information unit 131. Further, the acquired number "1" is stored in the acquired number unit 1312.

Further, for the product related to the product code "4900004", the product code "4900004" and the acquired number "1" are stored only in the barcode information unit 133. The product code "4900004" and the number of acquisitions are not stored in the tag information unit 132 (that is, the number of acquisitions "0" is stored). Therefore, the product code "4900004" is stored in the product code unit 1311 of the product information unit 131. Further, the acquired number "1" is stored in the acquired number unit 1312.

From here, the functional configuration of the self-POS terminal 1 will be described. FIG. 6 is a functional block diagram showing a functional configuration of the self-POS terminal 1. As shown in FIG. 6, the control unit 100 of the self-POS terminal 1 is stored in the control program unit 141, and by following the control program expanded in the RAM 13, the tag information reading determination unit 101, the first storage unit 102, and the product It functions as a code acquisition determination unit 103, a second storage unit 104, a determination unit 105, and a processing unit 106.

The tag information reading determination unit 101 determines whether the tag reader 30 has read the tag information by receiving the tag information stored in the wireless tag attached to the product by the antenna 27.

The first storage unit 102 stores the number of acquired product codes for each product code acquired based on the tag information stored in the wireless tag attached to the product received by the antenna 27. Specifically, the first storage unit 102 acquires a product code indicating the type of the product based on the individual product code included in the tag information read by the tag information reading determination unit 101, and the product code of the same type. The number of product codes acquired is stored for each item. More specifically, each time the product code is acquired, the first storage unit 102 counts up the number of acquired product codes stored in the acquired number unit 1322 by +1 and stores the product code.

The product code acquisition determination unit 103 determines whether or not the product code that specifies the type of the product has been acquired based on the symbol attached to the product. Specifically, the barcode reader 33 reads the symbol attached to the product passed by the customer. The product code acquisition determination unit 103 analyzes the symbol read by the barcode reader 33 and determines whether or not the product code of the product has been acquired.

The second storage unit 104 stores the number of acquired product codes for each product code acquired by reading the symbol attached to the product. Specifically, the second storage unit 104 stores the number of acquired product codes of the same type based on the product code acquired by the product code acquisition determination unit 103. More specifically, each time the second storage unit 104 acquires the product code, the acquisition number of the product code stored in the acquisition number unit 1332 is incremented by +1 and stored.

The determination unit 105 determines the magnitude of the number of acquired product codes stored in the first storage unit 102 and the number of acquired product codes stored in the second storage unit 104 for the same type of product. Specifically, the determination unit 105 compares the number of acquisitions stored in the acquisition number unit 1322 with the number of acquisitions stored in the acquisition number unit 1332, and determines which is larger.

The processing unit 106 executes processing based on the product code associated with the number of acquisitions determined by the determination unit 105 to be large. Specifically, the processing unit 106 executes a process of storing the product code and the number of acquisitions associated with the number of acquisitions determined by the determination unit 105 in the product information unit 131. This process is the sales registration process. In addition, the processing unit 106 notifies that the sales registration process has been executed based on the product code associated with the number of acquisitions determined by the determination unit 105 to be large. Further, the processing unit 106 displays on the display unit information indicating the medium (wireless tag or symbol) for which the product code associated with the acquisition number determined by the determination unit 105 to be large has been acquired.

Further, when the processing unit 106 acquires the product code based on only one of the tag information and the symbol for the same product, the processing unit 106 executes the sales registration process using the acquired product code.

From here, the control of the self-POS terminal 1 will be described. FIG. 7 is a flowchart showing the flow of control processing of the self-POS terminal 1. As shown in FIG. 7, the product code acquisition determination unit 103 of the self-POS terminal 1 determines whether or not the product code for specifying the product type has been acquired based on the thinn attached to the product imaged by the barcode reader 33. (S11).

If it is determined that the product code is not acquired based on the symbol (No in S11), then the tag information reading determination unit 101 receives the tag information stored in the wireless tag attached to the product by the antenna 27. Then, it is determined whether the tag reader 30 has read the tag information (S12). When the tag reader 30 determines that the tag information has been read (Yes in S12), the control unit 100 determines whether the tag information determined to have been read in S12 is duplicate information that has already been read (S13). ). When it is determined that the information is not duplicated (No in S13), the control unit 100 indicates the type of the product based on the individual product code included in the tag information determined to be read by the tag information reading determination unit 101. Acquire the product code (S14).

Next, the first storage unit 102 stores the following information in the tag information unit 132 with respect to the acquired product code (S15). If the acquired product code is already stored in the product code unit 1321, the number of acquisitions stored in the acquisition number unit 1322 associated with the product code is incremented by +1 (S15). If the acquired product code is not yet stored in the product code unit 1321, the product code is newly stored in the product code unit 1321 and the number of acquisitions is stored in the acquisition number unit 1322 corresponding to the product code. Memorize "1" (S15).

Next, the control unit 100 determines whether or not the product code based on the symbol related to the product code acquired based on the tag information has already been acquired (S16). If it is determined that the product code based on the symbol related to the product code has already been acquired (Yes in S16), the determination unit 105 acquires the product code stored in the first storage unit 102 for the same type of product. It is determined whether or not the number and the number of acquired product codes stored in the second storage unit 104 are large (S17). Specifically, the determination unit 105 has the number of acquisitions (the number of acquisitions of the product code acquired based on the tag information) stored in the number of acquisitions unit 1322 and the number of acquisitions (in the symbol) stored in the number of acquisitions unit 1332. It is determined whether or not the number of acquisitions stored in the acquisition number unit 1322 is larger by comparing with the number of acquisitions of the product code acquired based on this (S17). As described above, when both the wireless tag and the symbol are attached to the same product, the tag information is read earlier than the symbol in many cases, so that the judgment of S17 is often "Yes". In the case of "Yes" in S17, the product code based on the symbol has not yet been acquired for the product.

When it is determined that the number of acquisitions stored in the acquisition number unit 1322 is larger (Yes in S17), the processing unit 106 assigns the product code associated with the acquisition number determined by the determination unit 105 to be larger. The process is executed based on (S18). That is, the processing unit 106 displays information (for example, “wireless tag”) indicating the medium (wireless tag) from which the product code has been acquired on the display unit 22 (S18). Next, the processing unit 106 executes processing based on the product code associated with the number of acquisitions determined by the determination unit 105 to be large (S19). That is, the processing unit 106 executes the sales registration process related to the product based on the product code associated with the number of acquisitions determined by the determination unit 105 to be large (S19). Next, the processing unit 106 executes processing based on the product code associated with the number of acquisitions determined by the determination unit 105 to be large (S20). That is, the processing unit 106 sounds (notifies) a notification sound indicating that the sales registration process has been executed based on the product code associated with the number of acquisitions determined by the determination unit 105 to be large (S20).

On the other hand, in S17, when it is determined that the number of acquisitions stored in the acquisition number unit 1322 is not larger than the acquisition number stored in the acquisition number unit 1332 (Nos in S17), the control unit 100 processes. The processes of S18, S19, and S20 processed by the unit 106 are not executed. That is, the control unit 100 does not display the information indicating the medium from which the product code has been acquired on the display unit. Further, the control unit 100 does not execute the sales registration process related to the product based on the acquired product code. Further, the control unit 100 does not sound the notification sound based on the acquired product code.

Further, in S16, when it is determined that the product code based on the symbol related to the product code has not been acquired yet (No of S16), since the product code has been acquired for the first time, S18, without making the judgment of S17, The processes of S19 and S20 are executed.

On the other hand, when it is determined in S11 that the product code based on the symbol has been acquired (Yes in S11), the second storage unit 104 reads the symbol attached to the product and acquires the number of acquired products for each product code. Remember (S21). Specifically, the second storage unit 104 stores the number of acquired product codes of the same type based on the product code acquired by the product code acquisition determination unit 103 (S21). More specifically, when the acquired product code is already stored in the product code unit 1331, the second storage unit 104 is stored in the acquisition number unit 1332 associated with the product code. The number of acquisitions is increased by +1 (S21). If the acquired product code is not yet stored in the product code unit 1331, the product code is newly stored in the product code unit 1331, and the number of acquisitions is stored in the acquisition number unit 1332 corresponding to the product code. Memorize "1" (S21).

Next, the control unit 100 determines whether or not the product code based on the tag information related to the product code acquired based on the symbol has already been acquired (S22). When it is determined that the product code based on the tag information related to the product code has already been acquired (Yes in S22), the determination unit 105 determines that the product code stored in the first storage unit 102 for the same type of product. It is determined whether the number of acquisitions and the number of acquisitions of the product code stored in the second storage unit 104 are large (S23). Specifically, the determination unit 105 has the acquisition number (the number of acquisitions of the product code acquired based on the tag information) stored in the acquisition number unit 1322 and the acquisition number (in the symbol) stored in the acquisition number unit 1332. It is determined whether or not the number of acquisitions stored in the acquisition number unit 1332 is larger by comparing with the number of acquisitions of the product code acquired based on this (S23). In the case of "Yes" in S23, the product code based on the tag information has not yet been acquired for the product.

When it is determined that the number of acquisitions stored in the acquisition number unit 1332 is larger (Yes in S23), the processing unit 106 assigns the product code associated with the acquisition number determined by the determination unit 105 to be larger. The process is executed based on (S24). That is, the processing unit 106 displays information (for example, “bar code”) indicating the medium (wireless tag) from which the product code has been acquired on the display unit 22 (S24). Next, the processing unit 106 executes processing based on the product code associated with the number of acquisitions determined by the determination unit 105 to be large (S19). That is, the processing unit 106 executes the sales registration process based on the product code associated with the number of acquisitions determined by the determination unit 105 to be large (S19). Next, the processing unit 106 executes processing based on the product code associated with the number of acquisitions determined by the determination unit 105 to be large (S20). That is, the processing unit 106 sounds (notifies) a notification sound indicating that the sales registration process has been executed based on the product code associated with the number of acquisitions determined by the determination unit 105 to be large (S20).

On the other hand, when it is determined in S23 that the number of acquisitions stored in the acquisition number unit 1322 is larger (Nos in S23), the control unit 100 processes S24, S19, and S20 processed by the processing unit 106. Do not execute. That is, the control unit 100 does not display the information indicating the medium from which the product code has been acquired on the display unit. Further, the control unit 100 does not execute the sales registration process related to the product based on the acquired product code. Further, the control unit 100 does not sound the notification sound based on the acquired product code.

Further, in S22, when it is determined that the product code based on the tag information related to the product code has not been acquired yet (No of S22), since the product code has been acquired for the first time, S24 without making the judgment of S23. , S19, S20 are executed.

When the process of S20 is executed, when it is determined in S17 that the number of acquisitions stored in the acquisition number part 1322 is not larger than the number of acquisitions stored in the acquisition number part 1332 (No in S17), the process of S24 Is executed, when it is determined in S23 that the number of acquisitions stored in the acquisition number part 1332 is not larger than the number of acquisitions stored in the acquisition number part 1322 (No in S23), and in S12, the tag information If it is determined that the above is not read (No in S12), and if it is determined in S13 that the information is duplicated (Yes in S13), the control unit 100 then determines whether the end key 211 has been operated. (S31). When it is determined that the end key 211 has been operated (Yes in S31), the control unit 100 executes the settlement process based on the product information stored in the product information unit 131 (S32). Then, the control unit 100 clears the information stored in the product information unit 131, the tag information unit 132, and the barcode information unit 133 (S33). Then, the control unit 100 returns to S11.

If it is determined that the operation is not the end key 211 (No in S31), the control unit 100 returns to S11.
