Description

  The present invention relates to a POS terminal device and a bar code scanner that are used for clearing in a retail store or the like.

  It is expected that GS1 data including a plurality of information in one barcode will be introduced into the market in the future. However, since there are barcode scanners that cannot read the GS1 data bar in existing stores, the product supplier has already used the GS1 data bar for the same product, for example, the barcode of the JAN code. Is expected. In this case, if the product is large, the two barcodes can be placed at a position where they cannot be read by a single reading operation. However, in the case of small products, the position where both barcodes are attached is limited, so a scanner that can read both the GS1 data bar and the JAN code reads both barcodes with a single reading operation. There is a risk.

  As described above, when both barcodes of the GS1 data bar and JAN code are read, if the same product is included, the code includes a code for identifying a common product. There is a risk that two products will be registered despite going.

  An object of the present invention is to provide a POS terminal device and a barcode scanner capable of correctly registering a product even if a plurality of barcodes including a code for identifying the product are affixed to the product.

  In order to solve the above-described problems, the present invention provides a POS terminal capable of reading and registering a product barcode to which a first barcode and a second barcode, which are different types of barcodes, are attached. An apparatus, a bar code reading unit capable of reading a first bar code and a second bar code, and information for specifying a product is stored in the first bar code, and the second bar code Stores at least information for identifying a product. When the first barcode and the second barcode are read by the barcode reading means, the first barcode and the second barcode are used. First information determination means for determining whether or not the information for specifying the read product is the same, and information for specifying the same product is determined by the first information determination means, and the first barcode and the second barcode There when it is determined to have been read within a predetermined time, characterized by comprising a control means for processing as a registered one product.

  The POS terminal device further includes a selection unit that enables only the information specifying one product when the first information determination unit determines that the same product is specified. Is characterized in that registration processing is performed based on information for specifying the product selected by the selection means.

  The POS terminal device further comprises second information determining means for determining whether or not discount information is stored in the second barcode, and the discount information is stored by the second information determining means. If it is determined that the image data is registered, the control means performs a registration process based on the second bar code information.

  The present invention also provides a barcode scanner capable of reading a barcode of a product to which a first barcode and a second barcode, which are different types of barcodes, are attached. Stores information for identifying the product, and at least information for identifying the product is stored in the second barcode, and the first barcode and the second barcode are read by the barcode reading means. The first information determination means for determining whether or not the product information specifying the product read by the first barcode and the second barcode is the same, and the same information by the first information determination means POS terminal capable of communicating product information for identifying one product when it is determined that the first barcode and the second barcode have been read within a predetermined time apparatus And further comprising a transmission means for transmitting.

  According to the first aspect of the present invention, the first barcode and the second barcode, which are different types of barcodes, are read within a predetermined time, and it is determined that the information specifying the read products is the same. In such a case, since one product is registered, there is no possibility that two products are registered by mistake.

  According to the second aspect of the present invention, when it is determined by the first information determining means that the information for specifying the first barcode product and the information for specifying the second barcode product are the same. Has a selection means to select whether or not only the information specifying one product is valid, so select whether two products are registered by mistake or two products are registered You can proceed with registration according to the actual operation.

  According to the third aspect of the present invention, when the second information determining unit determines that the discount information is set in the second barcode, the control unit performs the registration process based on the second barcode information. Therefore, the merchandise registration is performed in consideration of the discount information, and the merchandise registration at the correct price becomes possible.

  According to the invention of claim 4, when it is determined by the information determining means that the information specifying the product with the first barcode and the information specifying the product with the second barcode are the same, Since information for identifying one product is transmitted to a POS terminal device that can communicate with the transmission means, when different types of barcodes are attached to the same product, both bar codes are used when registering the product. Even if the code is read, there is no possibility of being registered as two products by mistake. In addition, since the scanner makes the above determination, even when the function to be determined is introduced into an existing POS terminal device, the program on the POS terminal device side is not changed at all, and the introduction becomes easy.

  FIG. 2 is a block diagram showing an electrical system configuration of the POS terminal apparatus shown in FIG. The POS terminal device includes a ROM 15, a drawer 8, a communication control unit 17, a scanner communication unit 19, a checker unit control unit 22, and a casasha unit control unit 23 connected to a CPU (Central Processing Unit) 14 through a bus line 24. I have. The CPU 14 controls each unit of the POS terminal device. The ROM 15 stores control programs and character patterns used in the CPU 14. The RAM 16 includes registration buffers 1, 2, 3,..., PLU files,.

  An optical fiber 18 is connected to the communication control unit 17 so that data communication can be performed via the optical fiber 18. A scanner 9 is connected to the scanner communication unit 19, and data read by the scanner 9 is sent to the scanner communication unit 19. The checker unit control unit 22 is connected to the liquid crystal touch panel 12 on the clerk side, the second customer side display unit 11, and the second operation key unit 13. Further, the liquid crystal touch panel 20 on the store clerk side, the first customer side display unit 5, and the operation key unit 6 are connected to the cashier unit control unit 23.

  The POS terminal device is a master satellite type POS system, and the CPU 14 communicates with a master (not shown) by a polling / selecting method via the communication control unit 17 and the optical fiber 18, and is transmitted from the master. The product data such as the product name and the selling price corresponding to the Price Look Up) code are received, and various performance data such as the sales amount and the number of purchases corresponding to the PLU code stored in the PLU file of the RAM are transmitted to the master. The scanner communication control unit 19 controls communication with the scanner, and receives code data transmitted from the scanner 9 and transfers it to the CPU 14.

  FIG. 3 is a diagram showing a schematic configuration of the scanner 9. The scanner 9 uniformly irradiates light to a barcode 33 printed on a label 32 from a plurality of LEDs (light sources 31) through a barcode reading surface 9a (see FIG. 1), and the reflected light is emitted from the barcode 33 as a light source. The image of the bar code 33 is projected on the line sensor 37 via the mirror 35 and the lens 36 disposed behind the line 31, and the line sensor 37 is composed of 1000 to 2000 light receiving elements arranged in a line. The bar code 33 image thus converted is converted into an electrical signal in order from the end of the line sensor 37 and output to the control unit 40.

  FIG. 4 is a block diagram showing an electrical system configuration of the control unit 40 of the scanner 9. The control unit 40 includes a ROM 43, a RAM 44, a light source control unit 45, an A / D conversion unit 46, a decoding unit 47, and an interface 48 connected to the CPU 41 through a bus line 42. A light source 31 is connected to the light source controller 45. A line sensor 37 is connected to the A / D converter 46. The interface 48 is connected to the scanner communication unit 19 of the POS terminal device.

  The CPU 41 controls each unit by reading and executing a predetermined control program stored in the ROM 43. The RAM 44 is a storage unit that temporarily stores various data. The light source control unit 45 controls the light source 31 that irradiates the barcode 33 with light according to each reading method in the touch scan mode and the slide scan mode. That is, control is performed so that light is emitted from all LEDs of the light source 31 in the touch scan mode, and light is emitted only from some LEDs of the light source 31 in the slide scan mode. The A / D conversion unit 46 converts the electrical signal received from the line sensor 37 into a digital signal by an amplifier circuit and a digital conversion circuit (not shown).

  For the converted digital signal, the decoding unit 47 identifies a start code (a code for identifying the start of the barcode 33) and a stop code (a code for identifying the end of the barcode 33), and a bar and space time therebetween. Each code character is determined by measuring the interval, and the barcode 33 is analyzed by collating the combination of the code characters with a plurality of types of barcode information (not shown) stored in advance.

  FIG. 5 is a diagram showing a product example in which two different types of barcodes, that is, a barcode 103 using a GS1 data bar and a 13-digit barcode 104 of a JAN code are attached to one product. As shown in the drawing, a barcode 101 using a GS1 data bar and a 13-digit barcode 102 of a JAN code are attached to the surface of one product 100 having a product name AAA. In this way, the product 100 to which the barcode 101 by the GS1 data bar and the barcode 102 of the JAN code are pasted is placed on the fixed scanner 9 shown in FIG. 1 while holding the surface to which the product barcode is attached. When the code is read, two barcodes may be read at the same time. In this example, both barcodes are affixed at close positions. If it is a large product, it can also be affixed or printed at a position where the two barcodes are separated. However, in small confectionery and bakery products, the area where barcodes can be affixed or printed is limited, so both barcodes are inevitably affixed or printed at close positions, and barcode reading operations are performed once as described above. There is a risk that both barcodes will be read.

  FIG. 6A shows a recording area of the RAM 16. As shown in the figure, in the recording area, in addition to the flag and register areas, the registration buffer 1 stores the information read from the barcode regarding the product registered for the first customer, and the product registered for the customer A registration buffer 2 for storing information read from the barcode, a registration buffer 3 for storing information read from the barcode regarding the product registered by the third customer,..., Other PLU files, etc. Is remembered. FIG. 6B shows the contents of the registration buffer 1 when the bar code of the product shown in FIG. 5 is read. As shown in the figure, the registration buffer 1 stores a product identification code of 4987306655544 as the first and a product identification code of the same 4987306555544 as the second.

  FIG. 7 is a diagram showing a product registration processing flow of the POS terminal apparatus. Product registration processing will be described with reference to FIG. First, the barcode attached to the product is read in step ST1. When reading the barcode (hereinafter simply referred to as “GS1”) of the GS1 data bar attached to the product and the JAN code (hereinafter simply referred to as “JAN”), the barcode is irradiated with light from the light source 31. . The light reflected by the bar code is converted into an electric signal by the line sensor 37 and converted into a digital signal by the A / D converter 46. For the converted digital signal, a start code (a code for identifying the start of a barcode), a stop code (a code for identifying the end of the barcode), and a bar or space between them are measured to identify the barcode. .

  When the first barcode is identified as, for example, GS1 by one barcode reading operation, among the 14-digit information of the item whose AI (application identifier) is “01”, the top (most significant) The remaining 13 digits of information excluding the single digit information is specified as the product identification code (“4988706055554” in the example of FIG. 5), and as shown in FIG. Are stored. Further, when the bar code is continuously read and judged to be JAN, the read 13-digit identification code (“4988706055554” in the example of FIG. 5) is stored in the second. Further, the time from when the first barcode is read until the second barcode is read is measured and stored in a predetermined area of the RAM 16.

  Next, in step ST2, it is determined whether the two identification codes are sequentially stored in the registration buffer 1 of the RAM 16 by the barcode reading operation in step ST1, and if yes (Y), the process proceeds to step ST3, and no (N ), It is determined that one product identification code has been read, and the process proceeds to step ST7.

  In step ST3, it is determined whether or not the product identification codes stored in the registration buffer 1 in step ST1 are the same. If yes (Y), the process proceeds to step ST4. If no (N), the process proceeds to step ST10. To do.

  In step ST4, it is determined whether or not the two barcodes read in step ST1 have been read within a preset predetermined time, for example, 1 second. That is, it is determined whether or not the time stored in step ST1 is within a predetermined time. If yes (Y), the process proceeds to step ST5, and if no (N), the process proceeds to step ST10. That is, if it is within a predetermined time, it means that each bar code of a product with two barcodes attached to one product is scanned, and if a product identification code is stored for a predetermined time, The bar code affixed to another product is determined to be a scan.

  In step ST5, since it is determined that two barcodes attached to the same product have been scanned within a predetermined time, a display for selecting whether to cancel the second registration is displayed on the clerk side display unit 10 of the checker unit 4. To display. FIG. 8 shows an example of a display screen displayed on the clerk side display unit 10. As shown in the figure, a message “Do you want to cancel the second item because the same product has been read twice?” Is displayed, and “Yes” and “No” touch keys are displayed.

  In step ST6, it is determined whether the “Yes” touch key for canceling the second registration displayed in step ST5 is selected. If yes (Y), the product identification code stored in the registration buffer 1 is determined. The second code is cleared, and the process proceeds to step ST7. If no, the process proceeds to step ST10.

  In step ST7, it is determined whether or not the barcode of another product is read. If yes (Y), the process proceeds to step ST2, and the above process is repeated. If no (N), the process proceeds to step ST8.

  In step ST8, the contents stored in the registration buffer 1 of the RAM 16 are determined by pressing the current total key 13a arranged in the second operation key unit 13 of the checker unit 4.

  In step ST9, the data stored in the registration buffer 1 is read out by pressing the subtotal key 6a arranged in the operation key section of the cashier section 1, and the purchase price is calculated based on the total amount of the data and the PLU file. Calculated and settled by placing the amount deposited.

  In step ST10, in addition to the first product in the registration buffer 1 stored in step ST1, the second product is registered with the product identification code.

  In the product registration process, it is determined in step ST3 whether the product identification codes are the same. If yes (Y), it is then determined in step ST4 whether the two barcodes are read within a predetermined time. It may be determined whether reading of the two barcodes read in advance is within a predetermined time, and if yes (Y), it may be determined next whether they are the same product identification code.

  In the above embodiment, only the product identification code is stored in both GS1 and JAN, and only the product identification code with AI of “01” is identified. Since clearing either the first product identification code or the second product identification code does not change, the second product identification code was cleared in the above example, but the discount is added to the read GS1 code information. When the AI information corresponding to the information is included, the product identification code read from the JAN code is cleared. That is, in the previous example, only the product identification code is stored for both GS1 and JAN, so only the product identification code read from the barcode in the first and second storage areas of the registration buffer is stored. As shown in the example in which the information is stored, the “97” of AI that can be determined between companies is used as discount information, the barcode of GS1 is read, and the information of AI “97” is included and read. In addition to the merchandise identification code, the discount information with AI “97” is stored in the registration buffer 1 and further information indicating that the discount information is included (for example, following the merchandise identification code, There is a space before and after “97” indicating a discount, and a space after that is followed by a discount amount, for example, 100 indicating 100 yen). Thereby, as in the above example, even if the same product identification code is stored in the registration buffer 1, the product identification code without information (space 97 space) indicating that the discount information is included, That is, the product identification code read from the JAN code is cleared.

  In addition to the product identification code based on GS1, discount information (for example, 100 yen discount or 10% discount) is stored in the registration buffer 1. Therefore, the discount information and the discount information at the time of settlement in step ST9, Clearing processing is performed based on the price read from the product file shown in FIG. In the product file, as shown in FIG. 9, items of PLU code, product name, price,... Are provided and stored in the RAM 16. Note that the predetermined time in step ST4 can be set to an arbitrary time in the maintenance mode, for example. As described above, when the barcode is read with the scanner 9 facing the surface where the barcode of the product is attached, both barcodes may be read by one reading operation. If the same product identification code is registered as one product, and the discount information is included in GS1, it is registered with the product identification code based on GS1 and the discount information. Registered.

  In the above embodiment, it is determined whether or not two bar codes have been read by a single reading operation in the POS terminal device, but the determination is not performed by the POS terminal device but by the scanner. It may be. FIG. 10 is a diagram illustrating a processing flow in which the scanner determines whether two bar codes have been read.

  First, the barcode is read in step ST20. When reading GS1 and JAN, the bar code 33 is irradiated with light from the light source 31. The light reflected by the bar code 33 is converted into an electric signal by the line sensor 37 and converted into a digital signal by the A / D converter 46. A start code and a stop code are identified for the converted digital signal, and a bar code is specified by measuring a time interval between bars and spaces therebetween.

  When the first barcode is specified as GS1, for example, by one reading operation, the top (most significant digit) of the 14-digit information of the item whose AI is “01”, for example, one digit The remaining 13-digit information excluding information is specified as a product identification code, and the 13-digit product identification code is stored as, for example, the first area in the RAM 44 of the scanner 9 (corresponding to FIG. 6B). The If it is subsequently determined that JAN, the read 13-digit identification code is stored as the second predetermined area in the RAM 44 of the scanner 9. Further, the time until the first barcode is read and the second barcode is read is measured and stored in a predetermined area of the RAM 44 of the scanner 9.

  In step ST21, it is determined whether or not two product identification codes are sequentially stored in a predetermined area of the scanner RAM by the barcode reading operation in step ST20. If yes (Y), the process proceeds to step ST22. If no (N), it is determined that one commodity identification code has been read, and the process proceeds to step ST24.

  In step ST22, it is determined whether or not two barcodes have been read within a preset predetermined time, for example, 1 second. If yes (Y), the process proceeds to step ST23. If no (N), it is determined that two products have been read, and the process proceeds to step ST26.

  In step ST23, it is determined whether or not the product identification codes stored in step ST20 are the same. If yes (Y), the second product identification code stored in the predetermined area of the RAM 44 of the scanner 9 is cleared in step ST20, and the process proceeds to step ST24. If no (N), the process proceeds to step ST25.

  In step ST24, one product identification code stored in a predetermined area of the RAM 44 is transmitted to the CPU 14 of the POS terminal device via the interface 48 and the scanner communication unit 19 of the POS terminal device.

  In step ST25, it is determined whether or not the barcode of another product is read. If yes (Y), the process proceeds to step ST21, the above process is repeated, and if no, the process ends.

  In step ST26, it is determined that the barcode attached to each of the two products has been read, and the two product identification codes stored in step ST20 are sent to the POS terminal via the interface 48 and the scanner communication unit 19 of the POS terminal device. It is transmitted to the CPU 14 of the apparatus. In this way, two barcodes are read in one reading operation, and it is easy to determine whether the product identification codes are the same by the scanner, so there is no need to change the POS terminal device program. The same function can be executed by an existing POS terminal device.

  In the above embodiment, the POS terminal device in which the checker unit 4 and the cashier unit 1 are separated has been described. However, a POS terminal device in which the checker unit 4 and the cashier unit 1 are integrated may be used.

  In the above-described embodiment, the scanner is the vertical and fixed scanner 9, but it may be a hand scanner in which an operator holds the scanner by hand and reads a barcode. Further, an operation unit and a display unit may be provided in the scanner, and the selection shown in FIG. 8 may be displayed on the display unit in the scanner and selected by the operation unit.

  In the present invention, a barcode reading means capable of reading the first barcode and the second barcode, and information for specifying a product is set in the first barcode, When a plurality of identifiable items have information set therein, and the first barcode and the second barcode are read by the barcode reading means within a predetermined time, the first barcode The first information determination means for determining whether or not the information for specifying the product is included in a plurality of items of the second barcode, and the product of the first barcode is specified by the first information determination means When it is determined that the information is included in a plurality of items of the second barcode, the control means for processing as registration of one product is provided. Different kinds of bars like JAN Over de available more, as POS terminals and bar code scanners that can correct items registered as had been pasted to the same product.
