  The POS terminal 1 is provided with a keyboard 3 on the front side for an operator to input a deposit amount. The keyboard 3 is provided with a mode switch 4 in addition to a numeric key and a current key (not shown). The mode switch 4 is a switch for selecting various business modes such as “registration”, “inspection”, “settlement”, “setting”, and is operated with a key. Also, an operator main display 5 is connected to the front side of the POS terminal 1, and a customer sub-display 6 is connected to the back side. The main display 5 and the sub display 6 are composed of a liquid crystal display or the like, and display the product name and price of a product registered for sale, the total amount of a transaction, the amount of change, and the like.

  The POS terminal 1 has a built-in printer 7 for printing receipts and journals, and a receipt printed by the printer 7 is issued from a receipt issuing port 8 formed on the front side of the POS terminal 1.

  The POS terminal 1 is connected with a code scanner 9 for reading a barcode printed on a product label at the time of product sales registration. The code scanner 9 reads data including product codes such as JAN (Japanese Article Number), EAN (European Article Number), UPC (Universal Product Code), etc. from the barcode attached to the product, and the read data is POS. Output to the terminal 1.

  The code scanner 9 is configured to be able to switch between a plurality of formats for data communication (output) to the POS terminal 1. For example, the code scanner 9 has a numeric input mode and a scanner mode as formats related to data communication, and outputs data read from a barcode using either one of the input modes.

  FIG. 2 is a diagram illustrating an example of a data configuration in the numeric input mode. As shown in the figure, the numerical value input mode data D11 includes a numerical value input area A11 in which numerical values of a plurality of digits (for example, 13 digits) constituting the product code are input as numerical values, and the end of the numerical value. And an end input area A12 such as a tab key and a confirmation key.

  On the other hand, FIG. 3 is a diagram showing an example of the data configuration of the scanner mode. As shown in the figure, the scanner mode data D12 includes a data type area A21 to which information such as a numerical value indicating the type of barcode read (JAN, EAN, etc.) is input, and the number of digits of the read product code ( For example, it has a digit number area A22 for inputting 13 digits) and a data area A23 for inputting a numerical value representing a product code.

  As described above, the code scanner 9 is configured to be able to select one format from a plurality of formats, so that it can correspond to a format for each application described later. Note that the input mode switching (selection) method is not particularly limited. For example, it may be configured to be switched by a hardware switch such as a dip switch, or may be configured to switch the input mode by reading a mode switching barcode.

  The electrical system of the POS terminal 1 is configured as shown in FIG. Here, FIG. 4 is a diagram illustrating the configuration of the electrical system of the POS terminal 1.

  As shown in FIG. 4, the POS terminal 1 includes a control unit 11 having a computer configuration including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. By using the communication interface 13 connected to each other, online communication can be performed with a store computer (not shown).

  Also, the keyboard 3, the main display 5, the sub display 6, the printer 7, and the code scanner 9 are connected to the control unit 11 via the bus 12 and the I / O device control unit 14. A storage unit 15 including a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) is connected. In the storage unit 15, various control programs executed by the control unit 11 (CPU), setting information, and the like are stored in advance.

  The control unit 11 controls the operation of each unit constituting the POS terminal 1 by cooperating with the control program stored in the storage unit 15. For example, the control unit 11 causes the POS terminal 1 to realize a predetermined function by executing a control program (hereinafter referred to as another application) such as an OS or a spreadsheet application. It is assumed that other applications can handle data in the numeric input mode input from the code scanner 9.

  Further, the control unit 11 causes the POS terminal 1 to realize the functional configuration illustrated in FIG. 5 by cooperating with a control program (hereinafter referred to as a POS application) related to the POS business stored in the storage unit 15. Here, FIG. 5 is a diagram illustrating a functional configuration of the POS terminal 1. As shown in the figure, the POS terminal 1 includes an input reception unit 111, a data analysis unit 112, and a sales registration processing unit 113.

  The input receiving unit 111 receives input of data output from the code scanner 9 and determines the format of this data. Specifically, the input receiving unit 111 includes a first input receiving unit 111a and a second input receiving unit 111b that notify that data in the format is input for each format that can be switched by the code scanner 9. doing.

  Here, when the format of the data input from the code scanner 9 is the numeric input mode, the first input receiving unit 111a receives the data input from the code scanner 9 together with event information for notifying this mode. The data is output to the analysis unit 112. For example, when the first input receiving unit 111a receives data input in the numerical value input mode, the numerical value representing the product code is based on the data configuration of the data (the numerical value input area A11 and the terminal input area A12). A “numerical value input event” for notifying that an input has been made and a “termination input event” for notifying that a key representing the end has been input are output as event information.

  In addition, when the format of the data input from the code scanner 9 is the scanner mode, the second input receiving unit 111b receives the data input from the code scanner 9 together with the event information notifying the mode, and the data analysis unit 112. Output to. For example, when the second input receiving unit 111b receives the scanner mode data input, the scanner mode data is input based on the data configuration (data type area A21, digit number area A22, and data area A23). A “scanner event” for notifying that the event has been made is output as event information. As with the first input receiving unit 111a, an event may be output for each data configuration (data type area A21, digit number area A22, and data area A23).

  Here, the first input receiving unit 111a and the second input receiving unit 111b are not limited to being realized by the POS application, and may be realized by a part of the functions of the OS or the driver level. For example, since the OS has a function of accepting inputs such as numeric keys provided on the keyboard 3, the first input accepting unit 111a may be realized by using this function. The second input receiving unit 111b may be realized by a dedicated driver capable of handling scanner mode data.

  Further, in the present embodiment, the data input from the code scanner 9 is received in a two-stage configuration of the first input receiving unit 111a and the second input receiving unit 111b. Assume that as many input reception units as the number of formats that can be output are provided. The single input receiving unit 111 may identify the format of the data input from the code scanner 9 and output event information corresponding to the data format to the data analysis unit 112.

  Based on the event information notified from the input reception unit 111, the data analysis unit 112 extracts a product code from the data input from the code scanner 9 by an extraction method according to the format indicated by the event information.

  Specifically, when “numerical value input event” and “terminal input event” are notified as event information, the data analysis unit 112 immediately before the terminal input area A12 (tab key or confirm key) constituting the data. The number input in the existing number input area A11 is extracted as a product code. Further, when “scanner event” is notified as event information, the data analysis unit 112 extracts, as a product code, a numerical value corresponding to the number of digits input to the digit number area A22 from the data area A23 constituting the data. . It is assumed that the data analysis unit 112 supports the scanner mode data natively.

  The sales registration processing unit 113 uses the product code extracted by the data analysis unit 112 to execute sales registration processing for the product corresponding to the product code.

  Specifically, the sales registration processing unit 113 reads the product code with the code scanner 9, inputs the product with the numeric keys, and sets the number in the state where the mode switch 4 of the keyboard 3 is set to the checkout mode. The sales registration process starts when there is an input of the sales volume by the key.

  In the sales registration process, the sales registration processing unit 113 stores the product code input from the code scanner 9 and extracted by the data analysis unit 112 in the work area of the RAM. Further, the sales registration processing unit 113 stores the transaction type input from the keyboard 3 in the work area of the RAM. Here, examples of the transaction type include normal transactions, discount transactions, card payments, and the like.

  The sales registration processing unit 113 acquires a sales price, a product name, and the like by searching a product master table stored in a store computer (not shown) based on information stored in the work area. Sales data based on sales quantity, product name, sales price, etc. is generated. In the product master table, the product type, product name, unit price, and the like are registered in advance in association with the product code of each product.

  Thereafter, the sales registration processing unit 113 calculates the total sales amount every time a product code is input, and repeats this until the current key is pressed. When the current total key is pressed, the sales registration processing unit 113 registers this sales data in the store sales table of the store computer together with a transaction number for identifying this transaction.

  Next, information processing performed by the POS terminal 1 having the above-described configuration when the POS application is executed will be described with reference to FIG. Here, FIG. 6 is a flowchart illustrating an example of an information processing procedure executed by the POS terminal 1.

  When the barcode attached to the product is held over the code scanner 9 and the data is read from the barcode by the code scanner 9, the data is POSed in a preset input mode (numerical value input mode or scanner mode). The data is output to the terminal 1 (step S11).

  When the input receiving unit 111 receives data input from the code scanner 9 (step S12), the function of the first input receiving unit 111a and the second input receiving unit 111b determines the data format (step S13). Along with the event information for notifying the format, the input data is output to the data analysis unit 112 (step S14).

  Subsequently, based on the event information notified from the input receiving unit 111, the data analysis unit 112 extracts a product code from the data input from the code scanner 9 by an extraction method according to the format indicated by the event information ( Step S15). And the sales registration process part 113 performs a sales registration process using the product code extracted by step S15 (step S16), and complete | finishes this process.

  As described above, according to the present embodiment, the format of the data input from the code scanner 9 is automatically determined, and the product code is extracted from the data by the extraction method corresponding to the determined format. Thereby, since the product code used for the sales registration of the product can be extracted from the data of various formats input from the code scanner 9, the versatility of the POS terminal 1 related to the POS business can be improved.
