  Conventionally, a bar code and a service label attached in the vicinity of the bar code are imaged using an imaging device such as a CCD (Charge Coupled Device) image sensor, and a product code and a service label are obtained from the imaged image. A technique has been proposed to read the indicated service content. Further, in the related technology, the product code of each product to be read of the service label is registered in advance, and the reading time is shortened by reading the service label of only the registered product (product code). .

  However, as the number of product code registrations increases, the time required to search for product codes also increases, which may increase the time required to read service labels.

  The problem to be solved by the embodiments of the present invention is to provide a code reader and a program capable of efficiently reading a service label attached to a product.

  The code reading device according to the embodiment includes an imaging unit configured to image a product, a first detection unit configured to detect product information of the product from an image of the product imaged by the imaging unit, and the product imaged by the imaging unit. Product information of a product to be detected or not detected by the second detection unit is registered from a second detection unit that detects a service label indicating the content of the service given to the product from the image of Determination means for determining whether or not the product of the product information detected by the first detection unit is the detection target of the second detection unit based on the setting information, and the number of products of the service target product targeted for service provision And switching means for switching product information of a product to be registered in the setting information in accordance with the relationship between the number of products of the service non-target product to be excluded from the service provision.

The keyboard 31 is provided with a closing key and the like necessary for settlement of the commodity price. The POS terminal 3 has the same configuration and function as the POS terminal that is typically used 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 includes a reading window 21, a keyboard 22, a display for customer 23, a display for shop clerk 24, a buzzer 25, and an LED 26.

  The keyboard 22 accepts input with various keys when registering a product that can not be registered with the barcode. The customer display 23 displays the item name, the price, and the like of the registered product to the shopper or the clerk. The clerk display 24 displays the item name and price of the registered product, other error messages, and the like to the clerk of the operator.

  The code reading device 2 provided with the reading window 21 includes a camera 20 (imaging means) inside (see FIG. 2). The camera 20 may be an imaging device using, for example, a charge coupled device (CCD), or may be an imaging device using another imaging element such as a complementary metal oxide semiconductor (CMOS). The camera 20 picks up an article held over an imaging area facing the reading window 21.

  FIG. 2 is a diagram showing the configuration of the code reader 2 according to the first embodiment. The code reader 2 includes a CPU 50, a ROM 42, a RAM 43, a communication I / F 44, an output port 45, a keyboard controller 46, a display controller 47, connected by a bus line 41 such as an address bus or a data bus. 48, a camera controller 49, and a memory 27.

  The CPU 50 functions as a control unit that controls the overall operation of the code reader 2. The ROM 42 stores a program according to the present embodiment, other programs for controlling the operation of the CPU 50, various target product lists, 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 also 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 45 outputs a drive signal to the buzzer 25 and the LED 26. The keyboard controller 46 takes in key signals from the keyboard 22. The display controller 47 controls data display on the customer display 23. The display controller 48 controls data display on the display 24 for the store clerk. The camera controller 49 controls the imaging operation of the camera 20.

  The camera 20 images a code symbol (first symbol) such as a bar code or a two-dimensional code attached to a product, a label (service label) displaying a service such as discount or point addition, or the like.

  FIG. 3 is a view showing an example of the relationship between the product 60 and the imaging area of the camera 20. As shown in FIG. The imaging areas 70a and 70b surrounded by a two-dot chain line in the drawing are areas in which the camera 20 can capture an image in one frame. In addition to the bar code label 61, a discount label L1, which is an example of a service label, is attached to the product 60 shown in FIG.

  The barcode label 61 includes the commodity name “commodity A1” of the commodity 60, the commodity price “200 yen”, the barcode 62 and the like. In the bar code 62, information such as a product code is incorporated as product information necessary for registering sales data of the product 60 at the POS terminal 3. At the bottom of the barcode 62, a product code "2101234567890" incorporated in the barcode 62 is displayed. The discount label L1 displays character information “50 yen discount from the displayed price” indicating the discount amount for the product 60.

  The service label may be any label that is attached to the product 60 and displays the service provided at the time of sale registration of the product 60. That is, the service label is a display that indicates a predetermined service provided to the product information of the product 60 included in the barcode 62 by characters or symbols. As another example of the service label, a discount label indicating the discount rate of the product 60 or a point discount indicating the number of points to be provided to the customer who purchased the product 60 more than the normal number of point grants There is a label etc.

  As shown in FIG. 3, when the barcode 62 and the discount label L1 are separated and attached to each other in the product 60, the barcode 62 and the discount label L1 do not fit in the same imaging area. In such a case, the operator changes the position of the product 60 held over the reading window 21 and sets the product 60 a plurality of times by a plurality of frames of the imaging area 70a including the bar code 62 and the imaging area 70b including the discount label L1. Divide the image into

  Returning to FIG. 2, the memory 27 is a non-volatile memory such as a flash memory. The memory 27 stores various programs executed by the CPU 50 and various setting information such as the target product list F1.

  In the target product list F1, the product code of the product not to be detected by the service label detection unit 54 described later is registered. Specifically, in the present embodiment, the product code of a product (hereinafter referred to as a non-service target product) which is not targeted for service provision is registered in the target product list F1. The product code registration method is not particularly limited, and various forms can be adopted. For example, the product code may be registered individually for each service non-target product. Further, if the numerical values constituting the product code are partially common due to the same category etc., the common number sequence part (for example, the upper three digits) may be registered. A non-serviceable item is an item that is not discounted. Examples of non-serviceable products are cigarettes, liquor, books, tickets, CDs, securities (stamps, stamps, gift certificates, gift certificates, telephone cards, postal cards, meal tickets, etc.), and high-end products.

  Next, the functional configuration of the code reader 2 realized by the CPU 50 executing a program will be described. The CPU 50 operates in accordance with a program stored in the ROM 42 expanded in the RAM 43, thereby, as shown in FIG. 2, an image capturing unit 51, a barcode detection unit 52 (first detection unit), and a target product determination unit It functions as 53 (judgment means), service label detection unit 54 (second detection means), notification unit 55 (notification unit), and information output unit 56.

  The image capture unit 51 outputs an imaging on signal to the camera controller 49 to cause the camera 20 to start an imaging operation. Further, when receiving an instruction from the service label detection unit 54, the image capture unit 51 captures an image in the imaging area 70a or 70b (see FIG. 3) captured by the camera 20, and enters the image work area of the RAM 43. Store.

  The barcode detection unit 52 detects a code symbol from the image captured by the image capture unit 51. Specifically, detection of a barcode from the captured image by pattern matching technology, detection of a two-dimensional code from a predetermined finder pattern, and the like are performed. The barcode detection unit 52 converts a code symbol detected according to a predetermined decoding method into code information, and reads code information corresponding to the code symbol. For example, in the example of FIG. 3, the barcode detection unit 52 detects the barcode 62 and reads the product code “2101234567890” corresponding to the barcode 62.

  The target product determination unit 53 searches the target product list F1 for the product code read by the barcode detection unit 52, and determines whether the product code is registered in the target product list F1. If the target product determination unit 53 determines that the target product list F1 is registered, the target product determination unit 53 determines that the service label is not detected. If the target product determination unit 53 determines that the target product list F1 is not registered, the target product determination unit 53 determines that the service label is to be detected.

  By the way, in the prior art, the product code of the product for which the service is to be provided (hereinafter referred to as the service target product), that is, the product code of the product for which the service label is detected (read) is registered in advance. When read, the service label is detected. In addition, in stores that provide services such as discounts and point services, the number of products targeted for service tends to increase. However, in this case, as the number of product code registrations increases, the time required to search for the product code also increases, which may increase the time required to read the service label.

  Therefore, in the code reader 2 of the present embodiment, the product code of the non-service target product is registered in the target product list F1, and the service label is detected when a product code other than the registered product code is read. Control. This makes it possible to reduce the time required to search for the product code, even when the number of products for the service target product significantly exceeds the number of products for the non-service target product, so the service label reading efficiency can be improved. Can be done.

  The service label detection unit 54 detects a service label based on the determination result of the target product determination unit 53. Specifically, the service label detection unit 54 generates an image of the service label from the image stored in the image work area of the RAM 43 when the target product determination unit 53 determines that the service label is to be detected. To detect Further, while the timer 54a has not timed out, that is, while the predetermined time set in advance has not elapsed, the service label detection unit 54 continues to detect the service label.

  More specifically, when the timer 54 a has not timed out, and the service label detection unit 54 has not detected the service label, the service label detection unit 54 transmits an image to the image capture unit 51. Instructs you to Then, the image capture unit 51 newly captures an image in the imaging area captured by the camera 20, and the service label detection unit 54 performs a process of detecting a service label on the newly captured image.

  When the service label detection unit 54 detects an image of the service label, the service label detection unit 54 reads service information corresponding to the service label from the detected image of the service label.

  More specifically, the service label detection unit 54 detects the label by the image recognition technology using information indicating the feature (frame line, shape, etc.) of the service label, which is set in advance in the ROM 42 or the like. Then, the service label detection unit 54 performs a character recognition process such as an optical character reader (OCR) on the detected label, or performs pattern matching by object recognition, thereby displaying a discount amount displayed on the label, a discount rate, Read service information such as grant points. For example, in the example of FIG. 3, the service label detection unit 54 detects the discount label L1. Next, the service label detection unit 54 recognizes characters such as "50 yen" and "description" written on the discount label L1, and reads service information that is to be discounted by 50 yen.

  As described above, the operator can image the product 60 a plurality of times with the camera 20 during a predetermined time when the timer 54 a has not timed out. Therefore, even when the service label is not included in the imaging area 70a including the bar code label 61 as shown in FIG. 3, the operator can recapture an image by the imaging area 70b including the service label, Both code information and service information can be read reliably.

  The service label detection unit 54 is not limited to the identification process of character information, and may identify the color, size, shape, etc. of a label, a figure, etc. and read service information associated with those features. Good.

  When the target product determination unit 53 determines that the service label is to be detected, the notification unit 55 notifies the operator that a service label is attached to the product 60 or an instruction to read the service label.

  For example, when it is determined that the service label is attached to the product 60, the notification unit 55 sounds the buzzer 25 and controls the display controller 48, as shown in FIG. The first message such as “Please scan” is displayed on the display 24 for the store clerk. Furthermore, the notification unit 55 may cause the LED 26 to blink.

  Further, the notification unit 55 is a case where the target product determination unit 53 determines that the service label is to be detected, and the service label detection unit 54 does not detect a service label within the above-described predetermined time. The operator is notified that a service label is attached to the product 60 or an instruction to read the service label attached to the product 60.

  More specifically, the notification unit 55 makes the buzzer 25 sound when it is determined that the service label is to be detected, but the timer 54 a times out without detecting the service label. In addition, the notification unit 55 “does not have a discount label?” (See FIG. 5-1) or “the discount label is not read. Please scan the discount label” (FIG. 5-2). The second message such as reference) is displayed on the clerk display 24.

  The information output unit 56 outputs the code information read by the barcode detection unit 52 to the POS terminal 3 via the communication I / F 44. Further, when the service label detection unit 54 reads the service information, the information output unit 56 outputs the read service information to the POS terminal 3 together with the code information.

  Since the discount label L1 may not be attached depending on the product, the barcode detection unit 52 may only read the code information. Therefore, the information output unit 56 outputs, to the POS terminal 3, at least one of the code information read by the bar code detection unit 52 and the service information read by the service label detection unit 54.

  In addition, even if the service label is not detected and the timer 54a times out, the code information read by the bar code detection unit 52 is displayed when the enter key or the like of the keyboard 22 is pressed. Output to the POS terminal 3 only.

  That is, as described above, the second message (see FIG. 5-1) such as "Is there a discount label?" The clerk checks the product 60 to see if the service label is attached. Then, when it is determined that the service label is not attached to the product 60, the store clerk, for example, presses the enter key, and outputs only the previously read code information to the POS terminal 3. The POS terminal 3 performs sales registration of the product 60 based on the code information.

  In addition, although the service label is peeled off, etc., it is a product that should be discounted originally, but if the service label is not attached to the product 60, enter service information such as discount amount or discount rate from the keyboard 22 May be

  The POS terminal 3 receives the code information output from the information output unit 56 of the code reader 2 and performs sales registration of the product 60 using the received code information. When the POS terminal 3 receives the service information together with the code information, the POS terminal 3 adds the service corresponding to the service information to the product 60 and performs sales registration of the product 60.

  Next, the procedure of the information reading process performed by the code reading device 2 of the present embodiment will be described using FIG. FIG. 6 is a flowchart showing the procedure of the information reading process performed by the code reader 2.

  When receiving the scan start instruction from the POS terminal 3, the image capture unit 51 of the code reader 2 outputs an imaging on signal to the camera controller 49, and starts imaging by the camera 20 (step S11). The image capture unit 51 captures the image data of the image captured by the camera 20 into the image work area of the RAM 43 (step S12).

  The barcode detection unit 52 determines whether the image of the barcode 62 is detected in the captured image (step S13). When the image of the barcode 62 is not detected (step S13: No), the image capturing unit 51 continues the imaging by the camera 20 (step S12). When the image of the barcode 62 is detected (step S13: Yes), the barcode detection unit 52 reads code information corresponding to the detected barcode 62.

  Next, the target product determination unit 53 searches the code information (product code) read by the barcode detection unit 52 from the target product list F1 to determine whether the product code is registered in the target product list F1. Is determined (step S14). When the target product determination unit 53 determines that the service non-target product is registered in the target product list F1 (step S14: Yes), the target product determination unit 53 determines that the service label is not detected, and proceeds to step S23.

  When it is determined that the target product determination unit 53 is not registered in the target product list F1 (Step S14: No), the target product determination unit 53 determines that the service label is to be detected. In this case, the service label detection unit 54 measures the time for detecting the service label by starting the timer 54a (step S15), and detects the service label.

  In addition, the notification unit 55 sounds, for example, the buzzer 25 and displays a first message (see FIG. 4) such as “Please scan a discount label” on the store clerk display 24 to display the service label on the product 60. Informs that it has been attached (step S16). Then, the service label detection unit 54 determines whether or not the service label has been detected (step S17).

  When the service label is detected (step S17: Yes), the information output unit 56 decodes the barcode 62 and reads the code information (product code) and the service information read from the service label by the OCR or the like. Are output to the POS terminal 3 (step S18).

  When the service label is not detected (step S17: No), it is determined whether the timer 54a has timed out (step S19). When the time out occurs (step S19: Yes), the notification unit 55 sounds the buzzer 25, and the second display (see FIG. 5-1) such as "Is there a discount label?" The message is displayed, and the operator is notified again whether the service label is attached (step S20).

  On the other hand, when the operator confirms that the service label is not attached to the product 60 and presses the enter key of the keyboard 22 (step S21: Yes), the information output unit 56 generates code information (product code). Is output to the POS terminal 3 (step S23).

  On the other hand, when time-out does not occur at step S19 (step S19: No) or when the enter key is not pressed at step S21 (step S21: No), the image capturing unit 51 captures an image captured by the camera 20 Then (step S22), the process proceeds to step S17.

  After step S18 or step S23, the code reading device 2 determines whether the sale registration process has been completed from the POS terminal 3 and the end of the bar code reading process has been instructed (step S24). When the end of the bar code reading process is not instructed (Step S24: No), the process returns to Step S12 and the subsequent processes are continued. When the end of the barcode reading process is instructed (step S24: Yes), the code reading device 2 outputs an imaging off signal to the camera controller 49 (step S25), and ends the imaging by the camera 20.

  As described above, according to the code reading device 2 of the first embodiment, the product code of the product to be excluded from the detection target of the service label is registered in the target product list F1, and the product code other than the registered product code is When read, the service label is detected. As a result, when the number of products to which the service label is added becomes larger than the number of products to which the service label is not added, the product code search time can be reduced, so that the service label can be read efficiently. Can. Further, according to the code reading device 2 of the first embodiment, when it is determined that the product is a non-service target product, the service label is not detected, so that it is possible to prevent fraud. That is, even if the discount label is intentionally removed from the discounted product and the discount label is attached to the non-discounted product, the discount is not discounted from the non-discounted product. At this time, it may be displayed on the store clerk display 24 that the discount label is attached to the product which is not the discount product.

Second Embodiment
In the first embodiment, the product code registered in the target product list F1 is excluded from the detection target of the service label. However, it is also assumed that the number of products to which the service label is added is smaller than the number of products to which the service label is not added. Therefore, in the second embodiment, the product code to be registered in the target product list F1 is switched according to the ratio between the number of products to which the service label is added that occupies the total number of products and the number of products to which the service label is not added. The possible configurations will be described. In addition, about the component similar to 1st Embodiment, the same code | symbol is provided and description is abbreviate | omitted.

  FIG. 7 is a block diagram showing the configuration of the code reader 2a according to the second embodiment. The code reader 2a includes a CPU 50, a ROM 42, a RAM 43, a communication I / F 44, an output port 45, a keyboard controller 46, a display controller 47, which are connected by a bus line 41 such as an address bus or data bus. 48, a camera controller 49, and a memory 27. Further, the memory 27 stores the target product list F1.

  Next, the functional configuration of the code reading device 2a realized by the CPU 50 executing a program will be described. The CPU 50 operates in accordance with the program stored in the ROM 42 expanded in the RAM 43, whereby the image capture unit 51, the bar code detection unit 52, the service label detection unit 54, and the notification unit 55 are operated as shown in FIG. These functions as the information output unit 56, the target product switching unit 57 (switching unit), and the target product determination unit 58 (determination unit).

  The target product switching unit 57 has a function of switching the product code registered in the target product list F1 according to the ratio of the number of products to which the service label is added and the number of products to which the service label is not added. Specifically, the target product switching unit 57 counts the number of product codes of products to which service labels are added (or the number of product codes of products to which service labels are not added, with respect to the total number of product codes used in the store. Calculate the ratio of

  Here, “total number (number) of product codes” means the number of product codes represented by different number sequences, and the product codes represented by the same number sequence are handled as one product code. In this embodiment, the total number of product codes used in the store is an integrated value of the number of product codes of products to which service labels are added and the number of product codes of products to which service labels are not added. Is assumed.

  The target product switching unit 57 calculates the ratio between the number of products to which the service label is to be added and the number of products to which the service label is not to be added, based on the above calculation result. The target product switching unit 57 adds the service label when the ratio of the product to which the service label is to be added is equal to or more than a predetermined threshold (for example, 50%) Register the product code of the product not to be sold in the target product list F1. Then, the target product switching unit 57 instructs the target product determination unit 58 to perform the first setting for excluding the product code registered in the target product list F1 as the detection target of the service label.

  Further, the target product switching unit 57 adds the service label when the ratio of the products to which the service label is to be added is less than a threshold (for example, 50%) (or the ratio of the products to which the service label is not to be added is the threshold The product code of the product to be registered is registered in the target product list F1. Then, the target product switching unit 57 instructs the target product determination unit 58 to make a second setting in which the product code registered in the target product list F1 is the detection target of the service label.

  The target product determination unit 58 is a functional unit corresponding to the target product determination unit 53 described above. The target product determination unit 58 switches the determination criteria as to whether or not the product code registered in the target product list F1 is to be detected in response to the instruction from the target product switching unit 57.

  Specifically, when the first setting is instructed from the target product switching unit 57, the target product determining unit 58 performs the determination process with the product code registered in the target product list F1 as not to be detected. In addition, when the second setting is instructed from the target product switching unit 57, the target product determining unit 58 performs a determination process on the product code registered in the target product list F1 as a detection target.

  Then, the target product determination unit 58 searches the target product list F1 for the product code read by the barcode detection unit 52, and when the product code is registered in the target product list F1, the determination is made according to the above determination criteria. Do the processing.

  As described above, in this embodiment, the ratio between the number of products to which the service label is added and the number of products to which the service label is not calculated is calculated, and the product code of the product having a small ratio is registered in the target product list F1. . Further, in the present embodiment, along with the update of the target product list F1, the determination criteria of the target product determination unit 58 are switched. Thereby, even if the number of products of the service target product greatly exceeds the number of non-service target products or the opposite event occurs, the time required for the product code search As a result, the service label can be read efficiently.

  Next, the procedure of the update (switching) process of the target product list F1 executed by the code reading device 2a of the present embodiment will be described using FIG. FIG. 8 is a flowchart showing the procedure of the setting switching process performed by the code reader 2a. As a premise of this process, it is assumed that each of the product codes used in the store is stored in the memory 27 as setting information. Further, it is assumed that either one or both of the product code of the product to which the service label is added and the product code of the product to which the service label is not added is stored in the memory 27 as setting information.

  First, the target product switching unit 57 calculates the total number of product codes used in the store (step S31). Further, the target product switching unit 57 calculates the number of product codes of the service target product (step S32).

  Subsequently, the target product switching unit 57 calculates the ratio of the number of product codes calculated in step S32 to the total number of product codes calculated in step S31, that is, the ratio of the service target products (step S33). Next, the target product switching unit 57 determines whether the ratio calculated in step S33 is equal to or more than the threshold (step S34).

  If the target product switching unit 57 determines that the value is equal to or greater than the threshold in step S34 (step S34: Yes), the target product switching unit 57 registers the product code of the service non-target product for which the service label is not added in the target product list F1 (step S35). Then, the target product switching unit 57 switches the determination criteria of the target product determination unit 58 to the first setting for excluding the product code of the target product list F1 as the detection target of the service label (step S36), and ends this processing.

  If the target product switching unit 57 determines that the value is less than the threshold in step S34 (step S34: No), the target product switching unit 57 registers the product code of the service target product to which the service label is added in the target product list F1 (step S37). Then, the target product switching unit 57 switches the determination criteria of the target product determination unit 58 to the second setting in which the product code of the target product list F1 is the detection target of the service label (step S38), and the present process is ended.

  In the above process, although the number of product codes of the service target product is calculated in step S32, the number of product codes of the non-service target product may be calculated. In this case, in the subsequent processing, the opposite determination and setting are performed.

  Further, the information reading process performed by the code reading device 2a of the second embodiment is the information reading process of the first embodiment except that the determination criteria of the target product determining unit 58 are switched by the setting of the target product determining unit 58. Is the same as Therefore, the description of the information reading process in the present embodiment is omitted.

  As described above, according to the code reading device 2a of the second embodiment, the target product list according to the ratio between the number of products to which the service label is added that occupies the total number of products and the number of products to which the service label is not added. Dynamically switch the product code registered in F1. As a result, when one of the service target product and the non-service target product becomes larger than the other, the search time for the product code from the target product list F1 can be reduced, so the service label can be read efficiently. It can be carried out. Further, according to the code reading device 2 of the second embodiment, when it is determined that the product is a non-service target product, detection of the service label is not performed, so that fraud can be prevented. That is, even if the discount label is intentionally removed from the discounted product and the discount label is attached to the non-discounted product, the discount is not discounted from the non-discounted product. At this time, it may be displayed on the store clerk display 24 that the discount label is attached to the product which is not the discount product.
