Description

  Embodiments described herein relate generally to a reader and a program.

  In recent years, as part of in-store promotions, more and more stores issue coupons, such as coupon receipts, with service information indicating services such as discounts offered at the time of the next product purchase, to customers who have purchased the product. (See Patent Document 1). The customer can receive a service printed on the presented cash voucher and indicated by the service information by presenting the cash voucher to the operator who performs the accounting for the merchandise at the next purchase of the merchandise.

  By the way, since a voucher such as a coupon receipt is generally a paper medium, there is a situation that it is illegally copied and repeatedly used. As a method to prevent such unauthorized use of cash vouchers, an operator who conducts accounting for products checks the contents of the expiration date printed on the cash voucher and collects the used cash voucher for unauthorized use. Although there is a method for preventing this, every time a cash voucher is presented, the operator must check and collect the cash voucher, which puts a burden on the work.

  The reading apparatus according to the embodiment includes an imaging unit, a capturing unit, a reading unit, a determining unit, and a prohibiting unit. The imaging means captures an image. The capturing means captures the captured image. The reading means detects a voucher image used instead of cash from the captured image, and reads voucher information for identifying a voucher from the detected voucher image. The determination means determines whether or not the read voucher information matches used voucher information for identifying a used voucher. The prohibiting means prohibits the use of a voucher identified by the read voucher information when it is determined that the read voucher information matches the used voucher information.

For example, as shown in FIG. 8, service information “−100YEN”, which means a discount of 100 yen, is stored in association with service display feature data “100, yen, discount”.

  Next, characteristic functions of the code reading device 2 of 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 first reading unit 52, the second reading unit 53, and the determination unit 54, a prohibition unit 55, an information output unit 56, and a notification unit 57.

  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 areas 70 a and 70 b captured by the camera 20 and stores them in the image work area of the RAM 43. Further, when receiving an instruction from the first reading unit 52 or the second reading unit 53, the image data capturing unit 51 captures image data in the imaging areas 70 a and 70 b captured by the camera 20, and the image in the RAM 43. Store in work area.

  Here, the image data captured by the image data capturing unit 51 will be described with reference to FIGS. 3, 4, 9, and 10. 9 and 10 are diagrams illustrating an example of the captured image data.

  As shown in FIG. 3, when receiving an instruction from the first reading unit 52, the image data capturing unit 51 is displayed on the image 901 of the barcode label 61 affixed to the product 60 and the barcode label 61. The image data 900 including the image 902 of the barcode 62 (see FIG. 9) is stored in the image work area of the RAM 43.

  Further, when receiving an instruction from the second reading unit 53, the image data capturing unit 51 stores the image data 1000 (see FIG. 10) including the image 1001 of the coupon voucher 80 b included in the receipt 80 with coupon voucher in the RAM 43. Store in the image work area. The image 1001 of the coupon ticket 80b includes a serial number 81, a store name 82, an expiration date 83, and a service display 84.

  The first reading unit 52 detects the image 902 of the barcode 62 from the image data 900 stored in the image work area of the RAM 43 by the image data capturing unit 51, and the product 60 of the product 60 from the detected image 902 of the barcode 62. A barcode reading process for reading information is performed.

  More specifically, the first reading unit 52 binarizes one frame of image data 900 (see FIG. 9) stored in the image work area of the RAM 43, and a data area relating to the barcode 62 in the binarized data. Whether or not exists is detected. When the first reading unit 52 detects a data area related to the barcode 62 in the captured image data 900, the first reading unit 52 decodes the barcode 62 and displays the barcode data (JAN code) C1 of J1 to J13 shown in FIG. Is read as product information of the product 60. FIG. 11 is a diagram for explaining the barcode data. The barcode data C1 includes a manufacturer code, a product code as product information, a check digit, and the like. The first reading unit 52 stores the read barcode data C1 in the barcode work area of the RAM 43.

  The second reading unit 53 instructs the image data capturing unit 51 to capture the image data 1000 when a coupon use key included in the keyboard 22 is pressed. Then, the second reading unit 53 detects the image 1001 of the coupon 80b from the image data 1000 stored in the image work area of the RAM 43 by the image data capturing unit 51, and is included in the detected image 1001 of the coupon 80b. The service information (see FIG. 8) is read from the service display 84.

  More specifically, the second reading unit 53 performs character recognition processing such as OCR (Optical Character Reader) on one frame of the image data 1000 (see FIG. 10) stored in the image work area of the RAM 43. . When the second reading unit 53 collates the characters, pictures, symbols, and other features included in the coupon ticket 80b with the service display feature table T4 and detects service display feature data having a high degree of coincidence, the coupon ticket 80b It is determined that the service display 84 is detected from the image 1001.

  Next, the second reading unit 53 reads service information corresponding to the detected service display feature data from the service display feature table T4. Further, the second 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.

  In the present embodiment, the second reading unit 53 detects the service display 84 by the character recognition process and reads the service information from the service display 84. However, the bar in which the contents of the service are incorporated in the coupon ticket 80b is used. If a code is included, the image data 1000 is binarized, and it is detected whether or not there is a data area related to the barcode in which the contents of the service are incorporated in the binarized data. When the data area is detected, the barcode is decoded and the service code C2 (see FIG. 12) is read as service information.

  FIG. 12 is a diagram for explaining a service code. 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 second reading unit 53 reads the serial number 81, the store name 82, and the expiration date 83 from the image 1001 of the coupon ticket 80b.

  More specifically, the second reading unit 53 performs character recognition processing such as OCR on one frame of image data 1000 (see FIG. 10) stored in the image work area of the RAM 43. The second reading unit 53 collates the characteristics such as characters, pictures, symbols, etc. included in the coupon ticket 80b with the tables T1 to T3, and has a high degree of coincidence (serial number characteristic data, store name characteristic data, expiration date). When the feature data is detected, it is determined that the serial number 81, the store name 82, and the expiration date 83 are detected from the image 1001 of the coupon ticket 80b.

  The second reading unit 53 reads the serial number 81, the store name 82, and the expiration date 83 corresponding to the detected data (serial number feature data, store name feature data, expiration date feature data) from each of the tables T1 to T3. .

  The determination unit 54 determines whether the coupon voucher 80b is valid using the serial number 81, the store name 82, and the expiration date 83 read by the second reading unit 53.

  Specifically, the determination unit 54 reads a master file that stores a serial number of a used coupon ticket from the POS terminal 3 or a host terminal (not shown) in the store via the communication I / F 44. Next, the determination unit 54 determines whether or not the serial number 81 read by the second reading unit 53 matches the serial number of the used coupon ticket stored in the read master file. When the serial number 81 read by the second reading unit 53 matches the serial number of the used coupon ticket stored in the master file, the determination unit 54 determines that the coupon ticket 80b is not valid. To do. If the serial number 81 read by the second reading unit 53 is not stored in the master file, the determination unit 54 stores the serial number 81 in the master file.

  The determination unit 54 determines whether the store name 82 read by the second reading unit 53 matches the store name of the store where the coupon ticket 80b is used. If the store name 82 read by the second reading unit 53 does not match the store name of the store where the coupon ticket 80b is used, the determining unit 54 determines that the coupon ticket 80b is not valid. .

  Further, the determination unit 54 determines whether or not the expiration date 83 read by the second reading unit 53 has passed the current date and time. Then, when the expiration date 83 read by the second reading unit 53 has passed the current date and time, the determination unit 54 determines that the coupon ticket 80b is not valid.

  When the determination unit 54 determines that the coupon ticket 80b is not valid, the prohibition unit 55 deletes the service code C2 stored in the service code work area of the RAM 43 by the second reading unit 53, and the second reading unit 53 The use of the coupon voucher 80b identified by the serial number 81 read by is prohibited.

  When the service code C2 generated by the second reading unit 53 is stored in the RAM 43, the information output unit 56 combines the service code C2 with the barcode data C1 stored in the RAM 43 by the first reading unit 52. Then, a composite code C3 is generated and output to the POS terminal 3.

  FIG. 13 is a diagram for explaining the composite code. 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. 4, when the coupon ticket 80 b includes a service display 84 of 100 yen discount, a service code obtained by digitizing the service information “−100YEN” read by the second reading unit 53. C2 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 “−100YEN”. 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. Furthermore, the POS terminal 3 performs sales registration of the product by discounting 100 yen from the read price based on the service code C2.

  When the product information is read by the first reading unit 52, the notification unit 57 outputs a barcode on signal to cause the display LED 24 to emit light in order to notify the operator that the product information is in a read state. . In addition, when the information output unit 56 outputs the composite code C3 or the barcode data C1 to the POS terminal 3, the notification unit 57 outputs a barcode off signal and turns off the display LED 24.

  Further, when the information output unit 56 outputs the barcode data C1 to the POS terminal 3, the notification unit 57 drives the buzzer 25 to read only the product information and not the service information. The first buzzer sound shown (for example, “beep”) is sounded.

  When the information output unit 56 outputs the composite data C3 to the POS terminal 3, the notification unit 57 drives the buzzer 25 to indicate that both the product information and the service information are read. Play a buzzer sound (for example, “beep”).

  Furthermore, when the determination unit 54 determines that the coupon voucher 80b is not valid, the notification unit 57 displays a message on the display 23 via the display controller 48 to notify that the voucher is illegally used.

  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 reader.

  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 S1401). The image data capturing unit 51 captures the image data 900 captured by the camera 20 into the image work area of the RAM 43 (step S1402). Then, the first reading unit 52 starts the barcode reading process described above (step S1403).

  The first reading unit 52 determines whether or not the image 902 of the barcode 62 has been detected in the barcode reading process of step S1403 (step S1404). When the image 902 of the barcode 62 is not detected (step S1404: No), the first reading unit 52 continues the imaging with the camera 20 (step S1402).

  When the image 902 of the barcode 62 is detected (step S1404: Yes), the notification unit 57 outputs a barcode on signal to light the display LED 24 (step S1405), and the image 902 of the barcode 62 is detected. The operator is notified that is detected. Next, the second reading unit 53 determines whether or not a coupon use key included in the keyboard 22 has been pressed (step S1406).

  Next, when the coupon use key included in the keyboard 22 is pressed (Step S1406: Yes) and the instruction from the second reading unit 53 is received, the image data capturing unit 51 receives new image data captured by the camera 20. 1000 is taken into the image work area of the RAM 43 (step S1407). Then, the second reading unit 53 starts reading the service information, serial number 81, store name 82, and expiration date 83 for the image data 1000 captured in the image work area of the RAM 43 in step S1407 (step S1408). ). Then, the determination unit 54 determines whether the coupon voucher 80b is valid using the serial number 81, the store name 82, and the expiration date 83 read by the second reading unit 53 (step S1409). .

  When it is determined that the coupon ticket 80b is valid (step S1409: Yes), the information output unit 56 stores the barcode data C1 stored in the barcode work area of the RAM 43 and the service code work area. The composite code C3 (see FIG. 13) is generated from the service code C2 that has been set (step S1410). Then, the information output unit 56 transmits and outputs the generated composite code C3 to the POS terminal 3 via the communication I / F 44 (step S1411). The notification unit 57 drives the buzzer 25 to make a second buzzer sound (step S1412). Further, the notification unit 57 outputs a bar code off signal and turns off the indicator such as an LED that has notified the operator that the product information has been read (step S1413).

  Thereafter, it is determined whether or not the end of the job is instructed by a command from the POS terminal 3 (step S1418). If the business end is not instructed (step S1418: No), the process returns to step S1402, and steps S1402 to S1418 are repeated until the sales registration of all the products is completed. When the business end is instructed (step S1418: Yes), the CPU 50 outputs an imaging off signal to the camera controller 49 (step S1419), and ends the imaging operation by the camera 20.

  On the other hand, when it is determined that the coupon ticket 80b is not valid (step S1409: No), the prohibition unit 55 deletes the service code C2 stored in the service code work area of the RAM 43 by the second reading unit 53. The use of the coupon ticket 80b identified by the serial number 81 read by the second reading unit 53 is prohibited. Further, the notification unit 57 displays a message on the display 23 to notify that the unauthorized use of the coupon ticket 80b has occurred (step S1414).

  Next, when a message is displayed on the display 23 and when the coupon use key included in the keyboard 22 is not pressed (step S1406: No), the information output unit 56 displays the bar stored in the barcode work area of the RAM 43. The code data C1 is transmitted and output to the POS terminal 3 via the communication I / F 44 (step S1415). The notification unit 57 drives the buzzer 25 to sound the first buzzer sound (step S1416). Further, the notification unit 57 outputs a bar code off signal and turns off the indicator such as an LED that has notified the operator that the product information has been read (step S1417). Thereafter, the CPU 50 proceeds to step S1418.

  As described above, according to the code reading device 2 according to the present embodiment, the image data 1000 including the image 1001 of the coupon 80b is captured, the captured image data 1000 is captured, and the coupon data 80b is extracted from the captured image data 1000. While detecting the image 1001, the serial number 81 is read from the image 1001 of the detected coupon 80b, and it is determined whether or not the read serial number 81 matches the serial number that identifies the used coupon ticket. If 81 matches the serial number of the used coupon ticket, the coupon certificate 80b identified by the read serial number 81 is prohibited, so that the coupon certificate can be used without the operator confirming or collecting the coupon certificate 80b. Since the unauthorized use of 80b can be prevented, It is possible to reduce the burden on the operator of the work caused by the use.
