Description

An embodiment of the present invention relates to an article information reading device and a program.

Conventionally, barcodes and other symbols attached to products, etc. are read with a barcode reader, etc., product codes that identify products with the relevant symbols are obtained, and sales of the products are registered based on the obtained product codes. There is an article information reading device such as a POS (Point of Sales) terminal that executes processing.

Recently, there is a POS terminal equipped with a function of attaching a wireless tag instead of a symbol to a product, reading the tag information transmitted by the wireless tag with a tag reader, and executing sales registration processing. Recently, products with only symbols and products with both symbols and wireless tags are sometimes sold together. and a tag reader.

The customer or store clerk takes out the product from the basket and reads the symbol. The barcode reader then reads the symbol. Moreover, 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 sales registration processing based on the tag information read from the wireless tag and sales registration based on the read symbol for one product. There is a risk of so-called double registration, in which both processes are performed, as if the sales registration process was performed for two products.

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

An article information reading apparatus according to an embodiment provides article specifying information for specifying the type of article acquired based on tag information stored in a wireless tag attached to an article received by an antenna, and the number of acquisitions of the article specifying information. and a second storage unit for storing the article specifying information specifying the type of the article acquired by reading the symbol attached to the article and the number of acquisitions of the article specifying information . a judgment unit for judging whether the number of acquisitions stored by the first storage unit and the number of acquisitions stored by the second storage unit for the article specifying information is larger or smaller; and a processing unit that executes sales registration processing for the acquired number of the articles based on the obtained article specifying information.

Embodiments will be described below with reference to the drawings. In the embodiments, a self-type POS terminal (hereinafter referred to as a "self-service POS terminal") where a customer performs sales registration operation and settlement operation will be described as an example of an article information reading device. Also, a product will be described as an example of an article. In addition, this invention is not limited by embodiment described below.

First, the self-POS terminal 1 will be described. The self-service POS terminal 1 includes a registration unit that reads tag information from a wireless tag (medium) attached to a product to be purchased, and a payment unit that performs payment operations for the product based on the read tag information. . The self-service POS terminal 1 also includes a registration unit that reads a symbol (medium) attached to a product to be purchased, and a payment unit that performs a payment operation for the product based on the read tag information. Both the sales registration operation at the registration unit and the settlement operation at the settlement unit are performed by the customer himself/herself. The self-POS terminal 1 executes sales registration processing based on the sales registration operation performed by the customer. Also, the self-POS terminal 1 executes payment processing based on the payment operation performed by the customer.

Here, the sales registration process is based on the product code (item specifying information) that specifies the type of product contained in the tag information read by the self-POS terminal 1, from the product master 142 (see FIG. 2). product information (product name, price, etc.), displays the read product information of the product, and stores the product information in the product information unit 131 (see FIG. 2). Settlement processing is based on the product information stored in the product information unit 131 along with the sales registration processing, displaying the total amount and tax amount related to the transaction, and calculating and displaying the change based on the deposit received from the customer. This refers to the process of issuing a receipt on which product information and payment information (total amount, deposit amount, change amount, etc.) are printed. Information combining product information and payment information is called sales information.

Here, the product code will be explained. The product code is information specifying the type of product. For example, the product code is information specifying XX milk. The product code is not information that individually identifies each individual item of ○○ milk. Information for individually specifying products of the same type is an individual product code (individual product specifying information). The product code is acquired by the self-POS terminal 1 by reading the symbol. The tag information transmitted from the wireless tag contains 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.

Next, the tag information section 132 will be described. The tag information unit 132 stores a product code that specifies the 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 section 132. As shown in FIG. As shown in FIG. 3 , the tag information section 132 has a product code section 1321 and an acquisition number section 1322 . The tag information section 132 stores the product code acquired for the first time in the product code section 1321 . Also, the tag information unit 132 stores the acquisition number “1” in the acquisition 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 acquisition number stored in the acquisition number unit 1322 by +1 and stores the product code. do.

In the example of FIG. 3, for the product code "4900001" stored in the product code field 1321, the acquisition number is "5". This indicates that the product code "4900001" has been obtained five times based on the read tag information. Also, the number of acquisitions for the product code "4900002" is "2", indicating that the product code "4900002" was acquired twice based on the read tag information. The number of acquisitions for the product code "4900003" is "1", indicating that the product code "4900003" was acquired once based on the read tag information.

Next, the barcode information section 133 will be described. The barcode information section 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 section 133. As shown in FIG. As shown in FIG. 4, the bar code information section 133 has a product code section 1331 and an acquisition number section 1332 . The barcode information section 133 stores the product code acquired for the first time in the product code section 1331 . Also, the barcode information unit 133 stores the acquisition number “1” in the acquisition number unit 1332 for the product code acquired for the first time. In addition, when the acquired product code is already stored in the product code unit 1331, the barcode information unit 133 increments the acquisition number stored in the acquisition number unit 1332 by +1. Remember.

In the example of FIG. 4, for the product code "4900001" stored in the product code field 1331, the acquisition number is "4". This indicates that the product code "4900001" has been obtained four times based on the read symbols. The number of acquisitions for the product code "4900002" is "2", indicating that the product code "4900002" was acquired twice based on the read symbol. Also, the number of acquisitions for the product code "4900004" is "1", indicating that the product code "4900004" was acquired once based on the read symbol.

Here, when comparing the product code stored in the tag information section 132 and the product code stored in the barcode information section 133, the product code "4900001" is The number of acquisitions “5” is stored in the bar code information section 133, and the number of acquisitions “4” is stored in the number of acquisitions section 1332 of the barcode information section 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. indicates that the symbol associated with the product code "4900001" has been read four times. That is, the tag reader 30 read all the tag information from the wireless tags attached to the products that passed five times. Also, the bar code reader 33 read the symbol attached to the product that passed five times four times (the symbol 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 bar code reader 33 side, or that the symbol was dirty and could not be read by the bar code reader 33, etc. is.

For the product code "4900002", the number of acquisitions "2" is stored in the number of acquisitions section 1322 of the tag information section 132, and the number of acquisitions "2" is also stored in the number of acquisitions section 1332 of the barcode information section 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. indicates that the symbol associated with the product code "4900002" has been read twice. That is, the tag reader 30 read the tag information twice from the wireless tag attached to the product that passed twice. In addition, the bar code reader 33 read the symbol attached to the product that passed twice.

For the product code "4900003", the tag reader 30 also read the tag information once from the wireless tag attached to the product that passed once. In addition, the bar code reader 33 once read the symbol attached to the product that passed once.

For the product code “4900004”, the acquisition number “1” is stored in the acquisition number section 1332 of the barcode information section 133 . However, the tag information section 132 does not store the product code and the number of acquisitions. This is because the product specified by the product code "4900004" is attached with a symbol but is not attached with a wireless tag. Therefore, when the commodity was passed, the barcode reader 33 read the symbol, but the tag reader 30 could not read the tag information.

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

For the product related to the product code “4900001”, the number of acquisitions “5” is stored in the number of acquisitions section 1322 and the number of acquisitions “4” is stored in the number of acquisitions section 1332 . Therefore, the product code portion 1311 of the product information portion 131 stores the product code “4900001”. Also, the number of acquisitions “5” is stored in the number of acquisitions section 1312 . This is because the acquisition number “5” stored in the acquisition number section 1322 is greater than the acquisition number “4” stored in the acquisition number section 1332 .

For the product related to the product code “4900002”, the number of acquisitions “2” is stored in the number of acquisitions section 1322 , and the number of acquisitions “2” is stored in the number of acquisitions section 1332 . Therefore, the product code portion 1311 of the product information portion 131 stores the product code “4900002”. Also, the number of acquisitions “2” is stored in the number of acquisitions section 1312 .

Similarly, for the product related to the product code “4900003”, the product code “4900003” is stored in the product code section 1311 of the product information section 131 . Also, the number of acquisitions “1” is stored in the number of acquisitions section 1312 .

As for the product related to the product code “4900004”, the product code “4900004” and the acquisition number “1” are stored only in the barcode information section 133 . The product code "4900004" and the acquisition number are not stored in the tag information section 132 (that is, the acquisition number "0" is stored). Therefore, the product code portion 1311 of the product information portion 131 stores the product code “4900004”. Also, the number of acquisitions “1” is stored in the number of acquisitions section 1312 .

From here, the functional configuration of the self-POS terminal 1 will be described. FIG. 6 is a functional block diagram showing the functional configuration of the self-POS terminal 1. As shown in FIG. As shown in FIG. 6, the control unit 100 of the self-POS terminal 1 operates according to the control program stored in the control program unit 141 and developed in the RAM 13 so that the tag information reading determination unit 101, the first storage unit 102, 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 receives the tag information stored in the wireless tag attached to the product through the antenna 27 and determines whether the tag reader 30 has read the tag information.

The first storage unit 102 stores the acquisition number of 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 the product code indicating the type of product based on the individual product code included in the tag information read by the tag information reading determination unit 101, and stores the product code of the same type. Stores the number of acquisitions of the product code for each. More specifically, each time a product code is acquired, the first storage unit 102 counts up the acquisition number of the product code stored in the acquisition number unit 1322 by +1 and stores the obtained product code.

The product code acquisition determination unit 103 determines whether a product code specifying the type of product has been acquired based on the symbol attached to the product. Specifically, the bar code 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 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, based on the product codes acquired by the product code acquisition determination unit 103, the second storage unit 104 stores the number of acquired product codes of the same type. More specifically, every time a product code is acquired, the second storage unit 104 increments the acquisition number of the product code stored in the acquisition number unit 1332 by +1 and stores the obtained product code.

The determination unit 105 determines whether 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 are larger or smaller. Specifically, the determination unit 105 compares the acquisition number stored in the acquisition number section 1322 and the acquisition number stored in the acquisition number section 1332, and determines which is larger.

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

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

From here, the control of the self-POS terminal 1 will be described. FIG. 7 is a flow chart showing the flow of control processing of the self-POS terminal 1. As shown in FIG. As shown in FIG. 7, the product code acquisition determination unit 103 of the self-service POS terminal 1 determines whether or not the product code specifying the type of product has been acquired based on the sticker 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 through 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 redundant information that has already been read (S13 ). If it is determined that the information is not duplicated information (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. A product code is acquired (S14).

Next, the first storage unit 102 stores the following information in the tag information unit 132 for the acquired product code (S15). When the acquired product code is already stored in the product code section 1321, the acquired number stored in the acquired product code section 1322 associated with the product code is incremented by +1 (S15). If the acquired product code is not yet stored in the product code field 1321, the product code is newly stored in the product code field 1321, "1" is stored (S15).

Next, the control unit 100 determines whether the product code based on the symbol associated with the product code obtained based on the tag information has already been obtained (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. A judgment is made as to whether the number is larger or smaller than the acquired number of product codes stored in the second storage unit 104 (S17). Specifically, the determination unit 105 determines the acquisition number stored in the acquisition number unit 1322 (acquisition number of product codes acquired based on the tag information) and the acquisition number stored in the acquisition number unit 1332 (symbol (Acquisition number of product codes acquired based on the number of acquisitions), and it is determined whether the number of acquisitions stored in the acquisition number unit 1322 is larger (S17). As described above, when both a wireless tag and a symbol are attached to the same product, the tag information is often read faster than the symbol, so the determination in S17 is often "Yes". If "Yes" in S17, the product code based on the symbol has not yet been acquired for the product.

If it is determined that the number of acquisitions stored in the number of acquisitions unit 1322 is greater (Yes in S17), the processing unit 106 adds the product code associated with the number of acquisitions determined to be larger by the determination unit 105. The processing 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 is acquired on the display unit 22 (S18). Next, the processing unit 106 executes processing based on the product code associated with the acquisition number determined to be large by the determination unit 105 (S19). That is, the processing unit 106 executes the sales registration process for the product based on the product code associated with the acquisition number determined to be large by the determination unit 105 (S19). Next, the processing unit 106 executes processing based on the product code associated with the acquisition number determined to be large by the determination unit 105 (S20). That is, the processing unit 106 emits (notifies) a notification sound indicating that the sales registration process has been executed based on the product code associated with the acquisition number determined to be large by the determination unit 105 (S20).

On the other hand, if it is determined in S17 that the number of acquisitions stored in the acquisition number unit 1322 is not greater than the number of acquisitions stored in the acquisition number unit 1332 (No in S17), the control unit 100 performs processing. The processing of S18, S19, and S20 processed by the unit 106 is not executed. That is, the control unit 100 does not display information indicating the medium from which the product code is acquired on the display unit. Also, the control unit 100 does not execute the sales registration process for the product based on the acquired product code. Also, the control unit 100 does not emit a notification sound based on the acquired product code.

If it is determined in S16 that the product code based on the symbol related to the product code has not yet been obtained (No in S16), the product code has been obtained for the first time. The processing of S19 and S20 is 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 stores the number of acquisitions for each product code acquired by reading the symbol attached to the product. Store (S21). Specifically, the second storage unit 104 stores the number of acquisitions of the same type of product code 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 stores the acquired product code in the acquisition number unit 1332 associated with the product code. The number of acquisitions is counted up by +1 (S21). If the acquired product code is not yet stored in the product code field 1331, the product code is newly stored in the product code field 1331, and the acquired product code is stored in the acquired product code field 1332. "1" is stored (S21).

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

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

On the other hand, if it is determined in S23 that the acquisition number stored in the acquisition number unit 1322 is larger (No in S23), the control unit 100 performs the processing of S24, S19, and S20 that the processing unit 106 processes. do not run That is, the control unit 100 does not display information indicating the medium from which the product code is acquired on the display unit. Also, the control unit 100 does not execute the sales registration process for the product based on the acquired product code. Also, the control unit 100 does not emit a notification sound based on the acquired product code.

In addition, if it is determined in S22 that the product code based on the tag information related to the product code has not yet been acquired (No in S22), the product code has been acquired for the first time, so the determination in S23 is not made in S24. , S19 and S20 are executed.

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

If it is determined that the end key 211 has not been operated (No in S31), the control section 100 returns to S11.

According to such an embodiment, 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. a second storage unit 104 for storing the number of acquired product codes for each product code acquired by reading symbols attached to products; 2 a judgment unit 105 for judging whether the number of acquisitions stored in the storage unit 104 is large or small, and a processing unit 106 for executing processing based on the product code associated with the number of acquisitions judged to be large by the judgment unit 105. prepared. Therefore, even if both the wireless tag and the symbol are read, the self-service POS terminal 1 does not perform double registration.

Further, according to the embodiment, the processing unit 106 executes the sales registration process of the product corresponding to the acquisition number using the product code associated with the acquisition number determined to be large by the determination unit 105 . Therefore, even if both the wireless tag and the symbol are read, the self-service POS terminal 1 does not perform double registration.

Further, according to the embodiment, when it is determined in S17 that the number of obtained product codes based on the tag information is large, and when it is determined in S23 that the number of obtained product codes based on the symbol is large, the processing unit 106 A notification sound is generated based on the product code used in the registration process. Therefore, even if both the tag information and the symbol are read, the notification sound is emitted only once. Therefore, the customer does not have a sense of suspicion that it might be double registration.
