  In the display control unit 223 described later, the nutrition display information stored in the nutrition display management file 216b is displayed for the customer using one predetermined display setting among the display settings defined in the display setting file 216c. Displayed on the device 204.

  Next, characteristic functions of the product code reading apparatus 200 will be described. As shown in FIG. 2, the CPU 211 cooperates with the program stored in the ROM 212 or the storage unit 216, as shown in FIG. 2, the image data capturing unit 221, the code reading unit 222, the display control unit 223, the nutrition display reading unit 224, and the information output The unit 225 is realized.

  The image data capturing unit 221 causes the imaging unit 215 to start an imaging operation by outputting an imaging on signal to the imaging unit 215. The image data capturing unit 221 captures image data in the imaging area 215 a captured by the imaging unit 215 and stores the image data in the RAM 213. Further, when receiving an instruction from the nutrition display reading unit 224, the image data capturing unit 221 captures the image data in the imaging region 215a captured by the imaging unit 215 and stores the image data in the RAM 213.

  The code reading unit 222 detects a barcode image from the image data stored in the RAM 213 by the image data capturing unit 221 and performs a barcode reading process of reading a product code from the detected barcode. Specifically, the code reading unit 222 binarizes one frame of image data stored in the RAM 213 and detects whether or not a data area related to a barcode exists in the binarized data. When the code reading unit 222 detects a data area related to the barcode, the code reading unit 222 decodes the barcode and reads the decoded data as a product code of the product G. The code reading unit 222 stores the read product code in the RAM 213.

  The display control unit 223 determines whether or not the nutrition display information corresponding to the product code read by the code reading unit 222 is stored in the nutrition display management file 216b. The nutrition display information to be displayed is displayed on the display 204 based on the display setting of the display setting file 216c.

  When the display control unit 223 determines that the nutrition display information corresponding to the product code is not stored in the nutrition display management file 216b, the display control unit 223 displays a message for prompting imaging of the nutrition display on the operator display 203, The nutrition display reading unit 224 is activated. In addition, since nutrition labeling is not attached to all products, for example, a product code representing a specific food set in advance or a product code registered in the nutrition labeling management file 216b (nutrient labeling information unregistered) Only), the presence / absence of nutrition label information may be determined.

  In addition, when the end of one transaction is instructed from the POS terminal 100, the display control unit 223 displays a predetermined component included in the component information of each product read from the nutrition display management file 216b until the end of the transaction. The total value is calculated based on the content etc. included in the product information of each food, and displayed on the display 204 for customers.

  For example, for the product with the product code “49002201337779” shown in FIG. 4, the display control unit 223 uses the energy 92 kcal per unit (per 20 g) based on the internal capacity 80 g of the product. By adding (multiplying), the energy 368 kcal of the product is calculated as the product component amount. Then, the display control unit 223 calculates the product component amount for each of the products targeted for sale registration in one transaction, and obtains the total value. In addition, the component used as the calculation object of merchandise component amount shall be predetermined.

  The nutrition display reading unit 224 performs nutrition display reading processing for detecting a character string of the nutrition display portion from one frame of image data stored in the image work area of the RAM 213 by the image data capturing unit 221.

  Specifically, when the display control unit 223 detects a character string of the nutrition display portion by a known technique such as pattern recognition or OCR character recognition in the nutrition display reading process, the code reading is performed using the detected character string as nutrition display information. The product code read by the unit 222 is registered in the nutrition display management file 216b in association with the product code. In addition, the nutrition display reading unit 224 automatically sorts the detected character string into component information, product information, and heading information based on specific words (for example, component names, names, highlighted characters, etc.) included in the character string. It is good also as a form which sorts, and it is good also as a form which the operator who operates the product code reading apparatus 200 performs manually.

  In addition, the nutrition display reading unit 224 switches the imaging mode of the imaging unit 215 to the close-up mode according to a predetermined operation input via the keyboard 202, and the nutrition display portion is displayed from the image taken by the imaging unit 215. The character string of is detected.

  The information output unit 225 transmits (outputs) the product code of the sales registration target product read by the code reading unit 222 to the POS terminal 100 through the communication I / F 214 together with the number of sales of the product.

  On the other hand, when the CPU 111 of the POS terminal 100 receives an input of a product code from the product code reader 200, the CPU 111 reads the price of the product corresponding to the product code with reference to the PLU file 114b. Then, the CPU 111 of the POS terminal 100 registers the sales of each product related to one transaction based on the price of the product read from the PLU file 114b and the number of sales of the product.

  Next, the operation of the checkout system of this embodiment will be described with reference to FIG. Here, FIG. 6 is a flowchart showing a procedure of information output processing performed by the product code reading apparatus 200.

  The CPU 211 of the commodity code reading device 200 starts an information output process when a transaction start is instructed by a predetermined signal from the POS terminal 100. The image data capturing unit 221 outputs an imaging on signal to the imaging unit 215, and starts an imaging operation by the imaging unit 215 (step S11). Next, the image data capturing unit 221 captures the image data captured by the image capturing unit 215 into the RAM 213 (step S12). Then, the code reading unit 222 starts the barcode reading process described above (step S13).

  The code reading unit 222 determines whether or not the barcode BC is detected in the barcode reading process of step S13 (step S14). If the barcode BC cannot be detected (step S14; No), the process returns to step S12 and the imaging by the imaging unit 215 is continued.

  When the code reading unit 222 reads the product code from the barcode BC by the barcode reading process (step S14; Yes), the display control unit 223 registers the nutrition display information corresponding to the product code in the nutrition display management file 216b. It is determined whether or not it has been performed (step S15). Here, when it determines with the nutrition display information having been registered (step S15; Yes), it transfers to step S22 immediately. On the other hand, when it is determined in step S15 that the nutrition display information is not registered (step S15; No), the display control unit 223 displays a message for prompting imaging of the nutrition display on the operator display 203 (step S16).

  Here, FIG. 7 is a diagram illustrating an example of a screen displayed on the display 203 by the process of step S16. In the figure, as a message prompting imaging of nutrition display, “adjust imaging range to component display area” is shown. In addition, an image of the imaging region 215a (component label L1) captured by the imaging unit 215 is displayed below the message. Thus, by displaying the captured image of the imaging unit 215 on the display device 203, the operator of the product code reading device 200 can grasp which position of the product is being captured.

  In FIG. 7, a selection button B1 is a button for instructing cancellation of registration, and a selection button B2 is a button for instructing a change to the close-up mode of the imaging unit 215. Note that the selection buttons B1 and B2 are selected by keyboard 202 or touch panel operation.

  Returning to FIG. 6, the nutrition display reading unit 224 determines whether cancellation of registration is instructed via the keyboard 202 (step S <b> 17). If cancellation of registration is instructed (step S17; Yes), the process proceeds to step S24.

  In addition, when an instruction to change to the close-up mode is received (step S17; No → step S18; Yes), the nutrition display reading unit 224 switches the image capturing mode of the image capturing unit 215 from the normal mode to the close-up mode (step S17). S19), the process proceeds to step S20. If no instruction to change to the close-up mode is given (step S18; No), the process immediately proceeds to step S20.

  Here, FIG. 8 is a diagram illustrating the relationship between the imaging region 215a and the nutrition display (component label L1) in the close-up mode. As shown in the figure, by switching to the close-up mode, it is possible to image the nutrition display portion more clearly, and thus it is possible to read the character string representing the nutrition display more accurately.

  Returning to FIG. 6, the nutrition display reading unit 224 determines whether or not the character string of the nutrition display portion is detected from the image captured by the imaging unit 215 (step S <b> 20), and when the nutrition display portion cannot be detected. (Step S20; No), it returns to Step S18 again. When the nutrition display part is detected (step S20; Yes), the nutrition display reading unit 224 uses the detected character string as nutrition display information, and associates it with the product code read in step S13, thereby providing the nutrition display management file 216b. (Step S21).

  As described above, the nutrition display reading unit 224 corresponds to the nutrition display management file 216b the product code and the nutrition display information read from the image data of the product when the nutrition display information is not registered in the nutrition display management file 216b. Add and register. Thereby, since it is possible to easily register nutrition display information, it is possible to improve convenience related to registration of nutrition display information.

  Subsequently, when the display control unit 223 reads the nutrition display information corresponding to the product code read in step S13 from the nutrition display management file 216b (step S22), the display control unit 223 sets the nutrition display information to the display setting of the display setting file 216c. Based on this, the data is displayed on the customer display 204 (step S23).

  Here, FIG. 9 is a diagram illustrating an example of a screen displayed on the display unit 204 in the process of step S23. This figure shows an example in which the nutrition display information of the product code “49002201337779” shown in FIG. 4 is displayed based on the display setting 2 of FIG. Thus, since nutrition display information can be presented to the customer in various display forms based on the display settings set in the display setting file 216c, it is possible to effectively present the nutrition display attached to the product. it can.

  Returning to FIG. 6, the information output unit 225 outputs the product code read in step S13 to the POS terminal 100 via the communication I / F 214 (step S24). Then, the CPU 211 determines whether or not a transaction end is instructed by a predetermined signal from the POS terminal 100 (step S25).

  Here, when the end of the transaction is not instructed (step S25; No), the process returns to step S12 again, and steps S12 to S25 are repeatedly executed until the sales registration of all the products is completed. When the end of the transaction is instructed (step S25; Yes), the image data capturing unit 221 outputs an imaging off signal to the imaging unit 215 (step S26), and stops the imaging operation by the imaging unit 215.

  Subsequently, the display control unit 223 converts the total value of the predetermined components included in the component information of each product read from the nutrition display management file 216b until the end of the transaction into the content amount included in the product information of each food. Based on the calculation (step S27). Then, the display control unit 223 displays the total value of the predetermined components calculated in step S27 on the customer display 204 (step S28), and ends the process.

  Here, FIG. 10 is a diagram illustrating an example of a screen displayed on the display unit 204 in the process of step S28. In the figure, the total energy value of each product (corn soup, pumpkin soup, French bread, etc.) purchased in one transaction is displayed as the total energy value. In addition, in FIG. 10, although it was set as the form which displays the sum total of energy, it is not restricted to this, You may make it the form which displays the total value calculated about other components (for example, protein, lipid, etc.) on the indicator 204. .

  As described above, for each product code read by the code reading unit 222 in one transaction, the total value of the predetermined components included in each of the nutrition display information corresponding to the product code is based on the content of each product. By calculating and presenting, the total value of the predetermined components included in all purchased products can be presented to the customer, so that the nutrition label attached to the product can be effectively presented.

  As described above, according to the product code reading apparatus 200 of the present embodiment, when a code symbol (product code) is read from the image data of the product imaged by the imaging unit 215, the product code is managed in association with the product code. The nutrition display information is displayed on the display 204 for customers. As described above, according to the product code reading apparatus 200 of the present embodiment, when the product code is read from the product, what kind of components are included in the product can be presented to the customer. It is possible to effectively present a nutritional label. In addition, since it is expected to improve the willingness to purchase products, it is possible to improve the re-purchasing (repeat) rate.

  The embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications, substitutions, additions, and the like are possible without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the nutrition component information and the total value of the predetermined components are displayed on the display 204 of the product code reading device 200 for each product that is the object of sales registration. The image information to be displayed on the display 204 may be transmitted to the POS terminal 100 to be displayed on the customer display 103 provided in the POS terminal 100.
