JP5386603B2 - Code reader, sales registration system and program - Google Patents

Description

  The present invention relates to a code reader, a sales registration system, and a program.

  Conventionally, in retail stores such as supermarkets, in order to reduce waste loss of fresh products, products are often discounted and sold as the closing time approaches. In this case, the store side affixes a discount label displaying a discount amount, a discount rate, etc. to the product to clearly indicate to the customer that the product is a discount product. In addition, when a discount label is affixed to a product purchased by a customer, a POS (Point of Sales) terminal operator reads the barcode of the product with a scanner and also relates to the discount from a keyboard, a touch panel, or the like. Process. For this reason, there is a possibility that the operator may sell the discounted product at a normal price without noticing the discount label.

  On the other hand, in Patent Document 1, a bar code and a discount label are simultaneously captured by a camera, and a product code and discount information read from the captured image are output to a POS terminal, whereby a discount process in the POS terminal is performed. A technique for automatically performing the above is disclosed.

  By the way, in the technique described in Patent Document 1, since the discount label and the barcode are picked up at a time, the discount label needs to be attached near the barcode. However, since the discount label is often attached manually by a store clerk, the position of the barcode and the discount label may be separated. In such a case, since the camera cannot pick up both images at the same time, the discount process cannot be performed automatically, and the operator performs the discount process manually by inputting from a keyboard or the like. .

  The present invention has been made in view of the above, and does not require a service provision processing operation such as a discount processing operation by an operator, for example. An apparatus, a sales registration system, and a program are provided.

  The code reading apparatus according to the embodiment includes an image capturing unit that captures an image captured by the image capturing unit, and purchase of product information or a product related to a product purchased by a customer from the one frame of the image captured by the image capturing unit. The first reading means for reading any one of service information indicating the service given at the time and the one frame image captured by the image capturing means, the product information or the service information among the service information. The other information different from the information read by one reading means is read, and when the other information is not read from the image of the one frame, a new image is taken in by the image taking means, A second reading means for reading the other information from the new image; the one information read by the first reading means; and the second reading hand. And an information output means for outputting said other information read is.

  In addition, the program according to the embodiment includes a computer that stores product information on a product purchased by a customer from an image capturing unit that captures an image captured by the image capturing unit and one frame of the image captured by the image capturing unit. From the first reading means for reading any one of the service information indicating the service given at the time of purchase of the product, and the one frame image captured by the image capturing means, the product information or the service information Of these, the other information different from the information read by the first reading means is read, and when the other information cannot be read from the image of the one frame, a new image is taken in by the image taking means. And the second reading means for reading the other information from the new image, and the one information read by the first reading means, And information output means for outputting said other information the second reading means read, to function as a.

  According to the present invention, even if only one of product information or service information can be read from an image of one frame, the other information that could not be read from a newly captured image is read, and product information and service information are output. Therefore, it is possible to automatically provide a service when purchasing a product without requiring an operator to perform a service providing process.

As shown in FIG. 1, the POS terminal 3 is provided with a keyboard 31, an operator display 32, a customer display 33, a printer 34 for printing receipts, a drawer 35 for storing cash and the like. It has been. The keyboard 31 is provided with a fastening key or the like necessary for settlement of the commodity price. The POS terminal 3 has the same configuration and functions as the POS terminal that is used as standard in this type of checkout lane system.

  The code reading device 2 is a device for reading a barcode attached to a product and outputting product information included in the barcode to the POS terminal 3. As shown in FIG. 1, the code reading device 2 mainly includes a reading window 21, a keyboard 22, a display 23, a display LED 24, and a buzzer 25. The keyboard 22 accepts input from various keys when registering a product that cannot be registered with a barcode. The display 23 displays the registered product name, price, etc. to the shopper. The display LED 24 is turned on when the barcode attached to the product is read to notify the operator that the barcode is being read. The buzzer 25 sounds a buzzer sound when the barcode attached to the product is read to notify the operator. A CCD (Charge Coupled Device) camera 20 (see FIG. 2) is built in the code reading device 2 provided with the reading window 21.

  FIG. 2 is a block diagram showing the configuration of the code reading device 2. The code reader 2 mainly includes a CPU 50, a ROM 42, a RAM 43, a communication I / F 44, an output port 46, a keyboard controller 47, a display controller 48, a camera controller 49, and a memory 45. These are connected by a bus line 41 such as an address bus or a data bus.

  The CPU 50 functions as a control unit that controls the entire operation of the code reading device 2. The ROM 42 stores a program according to the present embodiment, other programs for controlling the operation of the CPU 50, and the like. The RAM 43 functions as a work area when the CPU 50 develops various programs stored in the ROM 42. The RAM 43 stores various data such as image data captured by the camera 20.

  The communication I / F 44 controls data communication with the POS terminal 3 (see FIG. 1) connected via the bus. The output port 46 outputs a drive signal to the buzzer 25 and the display LED 24. The keyboard controller 47 captures key signals from the keyboard 22. The display controller 48 controls data display on the display 23. The camera controller 49 controls the imaging operation of the camera 20.

  The camera 20 images a code symbol such as a barcode or a two-dimensional code attached to a product, a label displaying a service such as discount or point addition.

  Next, the relationship between the product processed by the code reading device 2 of the present embodiment and the imaging area of the camera 20 will be described. FIG. 3 is a diagram illustrating an example of the relationship between the product 60 and the imaging area of the camera 20. A region surrounded by a two-dot chain line in the drawing is an imaging area 70a that is a region that the camera 20 can capture in one frame. In addition to the barcode label 61, a discount label L1, which is an example of a service display label, is attached to the product 60 shown in FIG.

  On the bar code label 61, the product name “pig rose thin cut”, the product price “200 yen”, the bar code 62, and the like are displayed. The bar code 62 incorporates information such as a product code as product information necessary for registering the sales data of the product 60 at the POS terminal 3. In addition, the product code “2101234567890” incorporated in the barcode 62 is displayed in the lower part of the barcode 62 as a number. In the discount label L1, character information “50 yen discount from display price” indicating the discount amount related to the product 60 is displayed.

  The service display label may be any label that is attached to the product 60 and displays a service related to the service provided when the product 60 is purchased. As other examples of the service display label, as shown in FIG. 4, a discount label L2 displaying the discount rate of the product 60, or as shown in FIG. There is a point premium label L3 or the like that displays the number of points that are added and awarded.

  The nonvolatile memory 45 stores a label feature table T that associates the characteristics of the service display label with the contents of the service indicated by the service display label.

  FIG. 6 is a diagram illustrating the label feature table T. As shown in FIG. 6, the label feature table T stores label feature data indicating the characteristics of characters and symbols included in the service display label and service information given to the product by the service display label in association with each other. ing.

  More specifically, the label feature data is information extracted from a service display label by character recognition processing such as OCR. That is, as shown in FIG. 3, for the discount label L1 described as “50 yen discount from display price”, as shown in the label feature data No. 1 in the label feature table T of FIG. , "Circle, pull" is extracted by the character recognition process. Similarly, for the labels L2 and L3 shown in FIGS. 2, no. As shown in the label feature data 3, information on discounts and point grants of “10,%, discount” and “10, points” is extracted.

  The service information is information obtained by converting information related to services such as discount information and point grant information read from the service display label into an alphanumeric value so that it can be used in the sales registration process of the POS terminal 3. That is, as shown in FIG. 6, the label feature data “50, yen, discount” is stored in association with service information “−50YEN” meaning a discount of 50 yen. Further, service information “−10%” meaning a discount of 10% is stored in association with the label feature data “10,%, discount”. Further, the service information “+ 10P”, which means a point increase of 10 points, is stored in association with the label feature data “10, points”.

  Next, characteristic functions of the code reading device 2 according to the present embodiment will be described. The CPU 50 operates in accordance with a program stored in the ROM 42 expanded in the RAM 43, so that as shown in FIG. 2, the image data capturing unit 51, the barcode reading unit 52, the label reading unit 53, and the information output unit 54 and functions as a notification unit 55.

  The image data capturing unit 51 outputs an imaging on signal to the camera controller 49 to cause the camera 20 to start an imaging operation. The image data capturing unit 51 captures image data in the imaging area 70 captured by the camera 20 and stores it in the image work area of the RAM 43. Further, when receiving an instruction from the label reading unit 53, the image data capturing unit 51 captures image data in the imaging area 70 captured by the camera 20 and stores it in the image work area of the RAM 43.

  Here, the image data D (Da, Db, Dc) captured by the image data capturing unit 51 will be described with reference to FIGS. 3 and 7 to 10.

  As shown in FIG. 3, when the barcode 62 and the discount label L1 are attached in close proximity to the product 60, the barcode 62 and the discount label L1 are stored in the imaging area 70a. In this case, the camera 20 can capture the barcode 62 and the discount label L1 in one frame. The image data capturing unit 51 stores image data Da (see FIG. 7) corresponding to the imaging area 70 a in the image work area of the RAM 43.

  On the other hand, as shown in FIG. 8, when the barcode 62 and the discount label L1 are pasted apart from each other on the product 60, the barcode 62 and the discount label L1 do not fit in the same imaging area 70. . In this case, the operator changes the position of the product 60 held over the reading window 21, and the product 60 is moved a plurality of times by a plurality of frames of the imaging area 70b including the barcode 62 and the imaging area 70c including the discount label L1. The image is divided into two. The image data capturing unit 51 captures the image data Db (see FIG. 9) and Dc (see FIG. 10) for the imaging areas 70b and 70c, respectively, and stores them in the image work area of the RAM 43.

  The barcode reading unit 52 detects the image of the barcode 62 from the image data stored in the image work area of the RAM 43 by the image data capturing unit 51 and reads the product information of the product 60 from the detected barcode 62. Read processing is performed.

  More specifically, the barcode reading unit 52 binarizes one frame of image data D (Da to Dc, see FIGS. 7, 9, and 10) stored in the image work area of the RAM 43. It is detected whether or not there is a data area related to the barcode 62 in the data. When the bar code reading unit 52 detects a data area related to the bar code 62 in the captured image data D, the bar code reading unit 52 decodes the bar code 62 and displays bar code data (JAN code) C1 of J1 to J13 shown in FIG. Is read as product information of the product 60. The barcode data C1 includes a manufacturer code, a product code as product information, a check digit, and the like. The barcode reading unit 52 stores the read barcode data C1 in the barcode work area of the RAM 43.

  The label reading unit 53 performs label reading processing for detecting an image of a service display label on the image data stored in the image work area of the RAM 43 by the image data capturing unit 51. The label reading unit 53 captures the image data by the image data capturing unit 51 for a predetermined time until the image of the service display label is detected. When the label reading unit 53 detects an image of the service display label within a predetermined time, the label reading unit 53 reads service information (see FIG. 6) from the detected service display label image.

  More specifically, the label reading unit 53 performs OCR (Optical Character) on one frame of image data D (Da to Dc, see FIGS. 7, 9, and 10) stored in the image work area of the RAM 43. Character recognition processing such as Reader). The label reading unit 53 collates the features such as characters, pictures, and symbols included in the service display label with the label feature data (see FIG. 6) of the label feature table T, and detects label feature data having a high degree of coincidence. In this case, it is determined that the service display label is detected in the image data D.

  Further, the label reading unit 53 reads service information corresponding to the detected label feature data from the label feature table T. Further, the label reading unit 53 encodes the read service information to generate a service code C2 (see FIG. 12) and stores it in the service code work area of the RAM 43.

  FIG. 12 is a diagram illustrating the service code C2. As shown in FIG. 12, the service code C2 includes a flag F for setting the type of service, and data P1 to P5 indicating the value of the provided service such as a discount amount, a discount rate, and the number of points granted. The flag F can represent the type of service as, for example, 1: discount rate, 2: discount amount, 3: points.

  Further, the label reading unit 53 controls the operation of the timer 56 that limits the time of label reading processing. When the service reading label is not detected and the timer 56 has not timed out, the label reading unit 53 instructs the image data capturing unit 51 to capture an image, and the camera 20 Causes the image data in the imaging area 70 that has been captured to be newly fetched.

  By doing so, the operator can take an image of the product 60 with the camera 20 a plurality of times only during a predetermined time when the timer 56 has not timed out. Accordingly, as shown in FIG. 8, even when the service display label is not attached to the imaging area 70b including the barcode label 61, the operator can re-image using the imaging area 70c including the service display label. Thus, the barcode data C1 and the service code C2 can be acquired.

  When the service code C2 generated by the label reading unit 53 is stored in the RAM 43, the information output unit 54 combines the service code C2 with the barcode data C1 stored in the RAM 43 by the barcode reading unit 52. The composite code C3 is generated and output to the POS terminal 3.

  FIG. 13 is a diagram for explaining the composite code C3. As shown in FIG. 13, the composite code C3 starts with a start code, and includes bar code data C1, a service code C2, a check digit CD of the service code C2, and a check digit CODE 128CD of the composite code C3. The code ends with a stop code. Based on the composite code C3 received from the code reading device 2, the POS terminal 3 performs sales registration in which the service indicated by the service code C2 is given to the product 60.

  As an example, as shown in FIG. 3, when a 50 yen discount label L1 is attached to the product 60, the service code C2 obtained by digitizing the service information “−50YEN” read by the label reading unit 53 Is generated. Therefore, the composite code C3 includes the barcode data C1 corresponding to the product code “21012345567890” and the service code C2 corresponding to “−50YEN”. The POS terminal 3 reads the price of the product 60 corresponding to the barcode data C1 with reference to a product master or the like held by the POS terminal 3 or a host terminal (not shown) in the store. Further, the POS terminal 3 performs merchandise sales registration by reducing 50 yen from the read price based on the service code C2.

  When the barcode reading unit 52 reads the barcode 62, the notification unit 55 outputs a barcode on signal and emits the display LED 24 to notify the operator that the barcode 62 is detected. Let Further, when the information output unit 54 outputs the composite code C3 or the barcode data C1 to the POS terminal 3, the notification unit 55 outputs a barcode off signal and turns off the display LED 24.

  Further, when the information output unit 54 outputs the barcode data C1 to the POS terminal 3, the notification unit 55 drives the buzzer 25 to read only the barcode label 61 and not the service display label. A first buzzer sound (for example, “beep”) indicating that the sound is generated is sounded.

  When the information output unit 54 outputs the composite data C3 to the POS terminal 3, the notification unit 55 drives the buzzer 25 to indicate that both the barcode label 61 and the service display label have been read. A second buzzer sound (for example, “beep”) is sounded.

  Next, the merchandise sales registration process performed by the code reader 2 will be described with reference to FIG. FIG. 14 is a flowchart showing a procedure of information output processing performed by the code reading device 2.

  The CPU 50 of the code reading device 2 starts an information output process when a job activation is instructed by a command from the POS terminal 3. The image data capturing unit 51 outputs an imaging on signal to the camera controller 49 and starts an imaging operation by the camera 20 (step S1). The image data capturing unit 51 captures image data D (Da, Db, Dc) captured by the camera 20 into the image work area of the RAM 43 (step S2). Then, the barcode reading unit 52 starts the barcode reading process described above (step S3).

  The barcode reading unit 52 determines whether or not the barcode 62 is detected in the barcode reading process of step S3 (step S4). If the barcode 62 has not been detected (step S4: No), the barcode reading unit 52 continues imaging with the camera 20 (step S2).

  If the barcode 62 is detected (step S4: Yes), the label reading unit 53 activates a timer 56 that limits the time of the label reading process (step S5). In addition, the notification unit 55 outputs a barcode on signal to turn on the display LED 24 (step S6), and notifies the operator that the barcode 62 has been detected.

  Next, the label reading unit 53 starts label reading processing on the image data captured in the image work area of the RAM 43 in step S2 (step S7). Then, the label reading unit 53 determines whether or not a service display label is detected in the label reading process in step S7 (step S8).

  When the service display label is detected (step S8: Yes), the information output unit 54 stores the barcode data C1 stored in the barcode work area of the RAM 43 and the service stored in the service code work area. A composite code C3 (see FIG. 13) is generated from the code C2 (step S9). Then, the information output unit 54 transmits and outputs the generated composite code C3 to the POS terminal 3 via the communication interface 44 (step S10). The notification unit 55 drives the buzzer 25 to generate a second buzzer sound (step S11). Furthermore, the notification unit 55 outputs a barcode off signal and turns off the indicator such as an LED that has notified the operator that the barcode is being read (step S12).

  Thereafter, it is determined whether or not the end of business is instructed by a command from the POS terminal 3 (step S18). When the business end is not instructed (step S18: No), the process returns to step S2, and steps S2 to S18 are repeated until the sales registration of all the products is completed. When the business end is instructed (step S18: Yes), the CPU 50 outputs an imaging off signal to the camera controller 49 (step S19), and the imaging operation by the camera 20 is ended.

  On the other hand, when the service display label is not detected (step S8: No), the label reading unit 53 determines whether or not the timer 56 started in step S5 has timed out (step S14).

  If the timer 56 has not timed out (step S14: No), the label reading unit 53 controls the image data capturing unit 51 to newly capture image data (step S13). Then, the label reading unit 53 performs a label reading process on the newly captured image (step S7).

  If the timer 56 has timed out (step S14: Yes), the information output unit 54 sends the barcode data C1 stored in the barcode work area of the RAM 43 to the POS terminal 3 via the communication interface 44. The transmission is output (step S15). The notification unit 55 drives the buzzer 25 to make a first buzzer sound (step S16). In addition, the notification unit 55 outputs a barcode off signal and turns off the indicator such as an LED that has notified the operator that the barcode 62 has been read (step S17). Thereafter, the CPU 50 proceeds to step S18.

  As described above, the code reader 2 has a waiting time for a predetermined time for reading the service display label, and a new image captured by the camera 20 is read until the service display label is read for the predetermined time. Accept image data. Thereby, even when the camera 20 cannot capture the barcode 62 and the service display label in one frame, it is possible to acquire the barcode data C1 and the service code C2 by capturing the product 60 a plurality of times. Become. Accordingly, it is possible to automatically perform service provision processing such as discount processing and point premium processing without requiring discount processing by the operator.

  In addition, as described above, the notification unit 55 changes the tone and number of buzzer sounds when both the barcode label 61 and the service display label are read and when only the barcode label 61 is read. To inform. Accordingly, the operator can easily determine whether or not the product has the service display label attached thereto based on the difference in the buzzer sound. Therefore, when the service is automatically given by the POS terminal 3 such as discount processing or point surcharge, there is an effect that the confirmation work by the operator can be easily performed.

(Second Embodiment)
Main products that are subject to discount include fresh foods processed and sold in stores. Generally, an in-store code starting with a specific numerical value (here, 2) is used as a product code attached to a product processed and sold in a store. That is, referring to FIG. 3, the product codes start with “2101234567890” and “2”, and it can be seen that this product 60 is provided with an in-store code.

  In the first embodiment, the waiting for reading the service display label is provided for a predetermined time after the barcode reading process is performed on all the products. However, for example, in a store that sells discounts only for products with an in-store code, it is only necessary to wait for reading of the service display label only for products with an in-store code. Therefore, the code reading device 202 according to the second embodiment determines whether or not the read product code is an in-store code, and if it is not an in-store code, outputs only the barcode data C1 to the POS terminal 3 immediately. It is characterized by doing.

  FIG. 15 is a block diagram illustrating a configuration of the code reading device 202 according to the second embodiment. The CPU 250 of the code reading device 202 further includes an in-store code determination unit 57, and includes an information output unit 254 different from the information output unit 54 according to the first embodiment. The same components as those of the code reading device 2 of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  The in-store code determination unit 57 refers to the barcode data C1 (see FIG. 11) read by the barcode reading unit 52, and indicates that the product code indicated by the barcode data C1 is an in-store code (service target information). Determine if it starts with a specific number. For example, when the specific numerical value is set to “2” and the product code indicated by the barcode data C1 starts with “2” such as “21012345567890”, the read barcode data C1 is an in-store code. Is determined.

  When the in-store code discriminating unit 57 discriminates that the bar code data C1 read by the bar code reading unit 52 is an in-store code, the information output unit 254 does not wait for the reading of the service display label for a predetermined time. Immediately, only the barcode data C1 stored in the RAM 43 is output to the POS terminal 3.

  Next, information output processing executed by the code reading device 202 will be described with reference to FIG. FIG. 16 is a flowchart illustrating a procedure of information output processing executed by the code reading device 202. The same processes as those in FIG. 14 are denoted by the same reference numerals, and description thereof is omitted here.

  The in-store code determination unit 57 determines whether or not the barcode 62 read in step S3 is an in-store code (step S20). If it is determined that the code is an in-store code (step S20: Yes), the process proceeds to step S5, and the processes after step S5 described above are performed. On the other hand, if it is determined that the code is not an in-store code (step S20: No), the information output unit 254 sends the barcode data C1 stored in the barcode work area of the RAM 43 to the POS terminal 3 via the communication interface 44. Are transmitted and output (step S21). The notification unit 55 drives the buzzer 25 to generate a first buzzer sound indicating that only the barcode 62 has been read (step S22), and proceeds to step S18.

  As described above, the code reading device 202 determines whether or not there is a possibility of discount from the read barcode 62, so that the service display label is read only for a product that may be discounted. Wait. Accordingly, since it is not necessary to provide a waiting time for reading the service display label for all products, the product sales registration process can be completed in a shorter time.

  In the above description, the barcode reader 52 reads the product information (barcode data C1) from the barcode 62 and then the label reader 53 reads the service information from the service display label. It is not limited to this. As another example, the bar code reading unit 52 may read the product information from the bar code 62 after the label reading unit 53 reads the service information from the service display label.

  In the above description, an example in which one service display label is affixed to the product 60 has been described. However, a plurality of service display labels may be affixed to the product 60. In this case, the information output units 54 and 254 combine the barcode data C1 and a plurality of service codes C2 read from each service display label to generate a composite code C3.

  In the above description, the label reading unit 53 reads the service information from the service display label, but information such as discounts and discounts is not limited to the form printed on the label. As another example, information such as discounts and discounts may be directly written on the product 60 or printed. The label reading unit 53 is not limited to the character information identification process, and may identify the color, size, shape, or the like of a label or a figure, and read service information associated with those features. .

  In the above description, the barcode reading unit 52 reads the barcode 62 attached to the product 60. However, the barcode reading unit 52 is not limited to this, and may read a two-dimensional code such as a code symbol. Further, although the barcode 62 is attached to the product 60 by the barcode label 61, the barcode 62 may be directly printed on the product.

  The program executed by the code reading devices 2 and 202 of the present embodiment is provided by being incorporated in advance in the ROM 42 or the like. The program executed by the code reading device 2 of the present embodiment is a file in an installable or executable format, such as a CD-ROM, a flexible disk (FD), a CD-R, a DVD (Digital Versatile Disk), or the like. The information may be provided by being recorded on a recording medium that can be read by the user.
