Description

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

  Conventionally, an image pickup device such as a CCD (Charge Coupled Device) image sensor is used to take an image of a barcode and a service label attached in the vicinity of the barcode, and a product code and a service label are obtained from the captured image. Techniques have been proposed for reading the service content shown. In addition, in this technology, the product code of each product for which the service label is to be read is registered in advance, and the service label is read only for the registered product (product code), thereby shortening the reading time. .

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

  A problem to be solved by an embodiment of the present invention is to provide a code reading apparatus and a program capable of efficiently reading a service label added to a product.

  The code reading apparatus according to the embodiment includes an imaging unit, a first detection unit, a second detection unit, and a determination unit. The imaging means images the product. The first detection unit detects the product information of the product from the image of the product captured by the imaging unit. The second detection unit detects a service label indicating the content of the service provided to the product from the image of the product captured by the imaging unit. The determination means determines whether or not a product with the product information detected by the first detection means is registered in a list in which product information of products that are not targeted for detection by the second detection means is registered. The second detection unit detects the service label when it is determined that the determination unit is not registered.

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 includes a reading window 21, a keyboard 22, a customer display 23, a store clerk display 24, a buzzer 25, and an LED 26.

  The keyboard 22 accepts input from various keys when registering a product that cannot be registered with a barcode. The customer display 23 displays the registered product name, price, etc. to the shopper or store clerk. The store clerk display 24 displays the registered product name, price, and other error messages to the operator store clerk.

  The code reading device 2 provided with the reading window 21 includes a camera 20 (imaging means) therein (see FIG. 2). The camera 20 may be an imaging device using, for example, a CCD (Charge Coupled Device), or may be an imaging device using another imaging element such as a CMOS (Complementary Metal Oxide Semiconductor). The camera 20 captures an image of a product held over an imaging area facing the reading window 21.

  FIG. 2 is a diagram illustrating a configuration of the code reading device 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, a display controller 47, which are 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 entire operation of the code reading device 2. The ROM 42 stores programs according to the present embodiment, other programs that control 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 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 store clerk display 24. The camera controller 49 controls the imaging operation of the camera 20.

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

  FIG. 3 is a diagram illustrating an example of the relationship between the product 60 and the imaging area of the camera 20. Imaging areas 70a and 70b surrounded by a two-dot chain line in the figure are areas in which the camera 20 can capture images in one frame. In addition to the barcode 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 product name “product A1” of the product 60, the product price “200 yen”, the barcode 62, and the like. In the barcode 62, information such as a product code is incorporated as product information necessary for registering the sales data of the product 60 at the POS terminal 3. The product code “2101234567890” incorporated in the barcode 62 is displayed below the barcode 62. The discount label L1 displays character information “50 yen discount from display price” indicating the discount amount related to the product 60.

  In addition, as a service label, what is attached | subjected to the goods 60 and displays the service provided at the time of sale registration of the goods 60 should just be displayed. In other words, the service label is a display indicating a predetermined service given to the product information of the product 60 included in the barcode 62 by characters or symbols. Other examples of service labels include a discount label that displays the discount rate of the product 60, and a point surcharge that displays the number of points that are given to the customer who purchased the product 60 in addition to the normal number of points granted. There are labels.

  As shown in FIG. 3, 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. In such a 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 70a including the barcode 62 and the imaging area 70b including the discount label L1. Take images separately.

  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, product codes of products that are not detected by the service label detection unit 54 described later are registered. Specifically, in the present embodiment, a product code of a product that is not subject to service grant (hereinafter referred to as a service non-target product) 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 individually registered for each service non-target product. In addition, when the numerical values constituting the product code are partially common due to reasons such as the same category, the common sequence portion (for example, the first three digits) may be registered. Non-service target products are products that are not discounted. Non-service target products are, for example, cigarettes, sake, books, tickets, CDs, securities (stamps, stamps, gift certificates, gift cards, telephone cards, postcards, meal tickets, etc.) and high-end products.

  Next, a functional configuration of the code reading device 2 that is realized by the CPU 50 executing the program will be described. The CPU 50 operates according to a program stored in the ROM 42 expanded in the RAM 43, so that as shown in FIG. 2, the image capturing unit 51, the barcode detection unit 52 (first detection means), and the target product determination unit 53 (determination unit), service label detection unit 54 (second detection unit), notification unit 55 (notification unit), and information output unit 56.

  The image capturing 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 stores it in 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, barcode detection by a pattern matching technique from a captured image, detection of a two-dimensional code from a predetermined finder pattern, and the like are performed. The barcode detection unit 52 converts the code symbol detected according to a predetermined decoding method into code information, and reads the 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 or not the product code is registered in the target product list F1. When the target product determination unit 53 determines that the target product list F1 is registered in the target product list F1, the target product determination unit 53 determines that the service label is not detected. Further, when the target product determination unit 53 determines that the target product list F1 is not registered in the target product list F1, the target product determination unit 53 determines that the service label is to be detected.

  By the way, in the conventional technology, a product code of a product for which a service is to be granted (hereinafter referred to as a service target product), that is, a product for which a service label is to be detected (read) is registered in advance. When it is read, the service label is detected. Further, 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 product codes also increases, which may increase the time required to read service labels.

  Therefore, in the code reading device 2 of the present embodiment, the product code of the service non-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 as follows. This makes it possible to reduce the time required to search for a product code even when the number of products subject to service greatly exceeds the number of products subject to non-service, so the service label can be read efficiently. Can be done automatically.

  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 determines the service label image from the image stored in the image work area of the RAM 43 by the image capture unit 51 when the target product determination unit 53 determines that the service label is to be detected. Is detected. Further, the service label detection unit 54 continues to detect the service label while the timer 54a has not timed out, that is, while a predetermined time has not elapsed.

  More specifically, the service label detection unit 54 performs image capture to the image capture unit 51 when the timer 54a has not timed out and while the service label detection unit 54 has not detected the service label. Instruct them to Then, the image capturing 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 for the newly captured image.

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

  More specifically, the service label detection unit 54 detects the label by image recognition technology using information indicating the characteristics (frame line, shape, etc.) of the service label set in advance in the ROM 42 or the like. Then, the service label detection unit 54 performs character recognition processing such as OCR (Optical Character Reader) on the detected label and pattern matching by object recognition, so that the discount amount, the discount rate, Read service information such as points granted. For example, in the example of FIG. 3, the service label detector 54 detects the discount label L1. Next, the service label detection unit 54 recognizes characters such as “50 yen” and “deduction” written on the discount label L1, and reads service information for performing 50 yen discount.

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

  Note that the service label detection unit 54 is not limited to the character information identification process, and can identify colors, sizes, shapes, and the like of labels and figures, 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 the product 60 has a service label attached or an instruction to read the service label.

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

  In addition, 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 the service label within the predetermined time. The operator is notified of the instruction that the service label is attached to the product 60 or the service label attached to the product 60 is read.

  More specifically, the notification unit 55 sounds the buzzer 25 when it is determined that the service label is to be detected but the timer 54a times out without detecting the service label. In addition, the notification unit 55 displays “Are there any discount labels?” (Refer to FIG. 5-1) or “No discount labels have been read. Scan the discount labels.” (FIG. 5-2 The second message such as “see” 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 at least one of the code information read by the barcode detection unit 52 and the service information read by the service label detection unit 54 to the POS terminal 3.

  The information output unit 56 also reads the code information read by the barcode detection unit 52 when the enter key or the like of the keyboard 22 is pressed even when the service label is not detected and the timer 54a times out. Only to the POS terminal 3.

  That is, as described above, the second message (see FIG. 5A) such as “Is there a discount label?” Is displayed on the store clerk display 24. The store clerk checks the product 60 to see if the service label is attached. If it is determined that the service label is not attached to the product 60, the store clerk presses the enter key, for example, and outputs only the previously read code information to the POS terminal 3. The POS terminal 3 registers the sale of the product 60 based on the code information.

  If the service label is peeled off and the product is to be discounted, but the product 60 has no service label, service information such as a discount amount and a discount rate is input from the keyboard 22. May be.

  The POS terminal 3 receives the code information output from the information output unit 56 of the code reading device 2 and registers the sale of the product 60 using the received code information. When the service information is received together with the code information, the POS terminal 3 gives a service corresponding to the service information to the product 60 and registers the product 60 for sale.

  Next, a procedure of information reading processing executed by the code reading device 2 of the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing a procedure of information reading processing executed by the code reading device 2.

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

  The barcode detection unit 52 determines whether an image of the barcode 62 has been 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 with the camera 20 (step S12). When an 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 target product list F1 for the code information (product code) read by the barcode detection unit 52, thereby determining whether or not the product code is registered in the target product list F1. Is determined (step S14). If 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.

  If 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 starts the timer 54a, measures the time for detecting the service label (step S15), and detects the service label.

  For example, the notification unit 55 sounds the buzzer 25 and displays a first message (see FIG. 4) such as “Please scan the discount label” on the store clerk display 24 to display the service label on the product 60. Is notified (step S16). Then, the service label detection unit 54 determines whether or not a 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 OCR or the like. Is output to the POS terminal 3 (step S18).

  If 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 displays a second message (see FIG. 5-1) such as “Is there a discount label?” On the clerk display 24. Then, the operator is notified again whether the service label is affixed (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 displays the code information (product code). Only to the POS terminal 3 (step S23).

  On the other hand, if the time-out has not occurred in step S19 (step S19: No) or the enter key has not been pressed in step S21 (step S21: No), the image capturing unit 51 captures an image captured by the camera 20. (Step S22), the process proceeds to Step S17.

  After step S18 or step S23, the code reading device 2 determines whether or not the sales registration process is finished from the POS terminal 3 and the end of the barcode reading process is instructed (step S24). If the end of the barcode 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 the imaging by the camera 20 is terminated.

  As described above, according to the code reading device 2 of the first embodiment, the product codes of the products that are not detected by the service label are registered in the target product list F1, and the product codes other than the registered product codes are registered. When it is read, the service label is detected. As a result, when the number of products to which service labels are added becomes larger than the number of products to which service labels are not added, the search time for product codes can be reduced, so service labels can be read efficiently. Can do. Further, according to the code reading device 2 of the first embodiment, when it is determined that the product is a service non-target product, since the service label is not detected, fraud can be prevented. That is, even if a discount label is intentionally peeled off from a discounted product and a discount label is attached to a product that is not a discounted product, no discount is given from a product that is not a discounted product. At this time, you may make it display on the display 24 for shop assistants that the discount label is stuck on the goods which are not discount goods.

[Second Embodiment]
In the first embodiment, the product code registered in the target product list F1 is excluded from the service label detection target. However, it may be assumed that the number of products to which service labels are added is smaller than the number of products to which service labels are not added. Therefore, in the second embodiment, the product codes to be registered in the target product list F1 are switched according to the ratio between the number of products to which service labels occupying the total number of products and the number of products to which no service labels are added. A possible configuration 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 reading device 2a according to the second embodiment. The code reading device 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, a bus line 41 such as an address bus and a data bus. 48, a camera controller 49, and a memory 27. The memory 27 stores the target product list F1.

  Next, a functional configuration of the code reading device 2a realized by the CPU 50 executing the program will be described. The CPU 50 operates according to a program stored in the ROM 42 expanded in the RAM 43, so that an image capturing unit 51, a barcode detection unit 52, a service label detection unit 54, and a notification unit 55 are operated as shown in FIG. And an information output unit 56, a target product switching unit 57 (switching unit), and a target product determination unit 58 (determination unit).

  The target product switching unit 57 has a function of switching the product code to be registered in the target product list F1 according to 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 added. Specifically, the target product switching unit 57 compares the total number of product codes used in the store with the number of product codes to which service labels are added (or the number of product codes with products that are not added with service labels). ) Is calculated.

  Here, the “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 the present embodiment, the total number of product codes used in the store is an integrated value of the number of product codes for products to which service labels are added and the number of product codes for 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 added and the number of products to which the service label is not added based on the above calculation result. The target product switching unit 57 adds a service label when the ratio of products to which service labels are added is equal to or greater than a predetermined threshold (for example, 50%) (or when the ratio of products to which service labels are not added is less than the threshold). The product code of the product not 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 perform the first setting for excluding the product code registered in the target product list F1 from the service label detection target.

  Further, the target product switching unit 57 adds the service label when the ratio of the product to which the service label is added is less than a threshold (for example, 50%) (or when the ratio of the product to which the service label is not added is equal to or greater than 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 perform the 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. In response to an instruction from the target product switching unit 57, the target product determination unit 58 switches a determination criterion as to whether or not the product code registered in the target product list F1 is a detection target.

  Specifically, when the first setting is instructed from the target product switching unit 57, the target product determination unit 58 performs a determination process with the product code registered in the target product list F1 as a detection target. In addition, when the second setting is instructed from the target product switching unit 57, the target product determination unit 58 performs a determination process using 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 determines that the product code is registered in the target product list F1 according to the above-described determination criteria. Process.

  As described above, in the present embodiment, the ratio between the number of products to which service labels are added and the number of products to which service labels are not added is calculated, and the product codes of products with a low ratio are registered in the target product list F1. . In the present embodiment, the determination criterion of the target product determination unit 58 is switched with the update of the target product list F1. As a result, even if the number of products subject to service is significantly greater than the number of products subject to service, or the opposite event occurs, the time required to search for product codes Therefore, 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 this embodiment will be described with reference to FIG. FIG. 8 is a flowchart illustrating a procedure of setting switching processing executed by the code reading device 2a. As a premise of this process, it is assumed that each product code used in the store is stored in the memory 27 as setting information. Further, it is assumed that 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). In addition, 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 service target products (step S33). Next, the target product switching unit 57 determines whether or not the ratio calculated in step S33 is equal to or greater than a threshold value (step S34).

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

  If the target product switching unit 57 determines that the value is less than the threshold value 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 criterion 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 ends this process.

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

  The information reading process executed by the code reading device 2a of the second embodiment is the information reading process of the first embodiment, except that the determination criterion of the target product determination unit 58 is switched by the setting of the target product determination unit 58. It is the same. Therefore, the description of the information reading process in this embodiment is omitted.

  As described above, according to the code reading device 2a of the second embodiment, the target product list is selected according to the ratio between the number of products to which the service labels occupy the total number of products and the number of products to which no service labels are added. The product code registered in F1 is dynamically switched. Thereby, when one of the service target product and the service non-target product is larger than the other, the search time of the product code from the target product list F1 can be reduced, so that 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 service non-target product, since the service label is not detected, fraud can be prevented. That is, even if a discount label is intentionally peeled off from a discounted product and a discount label is attached to a product that is not a discounted product, no discount is given from a product that is not a discounted product. At this time, you may make it display on the display 24 for shop assistants that the discount label is stuck on the goods which are not discount goods.

  As mentioned above, although embodiment of this invention was described, the said embodiment was shown as an example and is not intending limiting the range of invention. The above embodiment can be implemented in various other forms, and various omissions, replacements, changes, additions, combinations, and the like can be made without departing from the scope of the invention. Moreover, the said embodiment and its deformation | transformation are included in the range of the invention, the summary, and the invention described in the claim, and its equal range.

  For example, in the above-described embodiment, an example in which one service label is attached to the product 60 has been described. However, a plurality of service labels may be attached to the product 60. In this case, the information output unit 56 outputs a plurality of service information read from each service label to the POS terminal 3 together with the code information.

  Further, service information such as discounts and discounts and the barcode 62 are not limited to the form printed on the label. As another example, the service information and the barcode 62 may be directly described or printed on the product 60.

  The program executed by the code readers 2 and 2a of the above embodiment is provided by being incorporated in advance in the ROM 42, the memory 27, and the like. The programs executed by the code readers 2 and 2a of the above embodiment are files in an installable or executable format, such as CD-ROM, flexible disk (FD), CD-R, DVD (Digital Versatile Disk). ) Or the like may be recorded and provided on a computer-readable recording medium.

  Furthermore, the program executed by the code readers 2 and 2a of the above-described embodiment may be provided by being stored on a computer connected to a network such as the Internet and downloaded via the network. The program executed by the code readers 2 and 2a of the above embodiment may be provided or distributed via a network such as the Internet.

  The program executed by the code readers 2 and 2a of the above embodiment includes the above-described units (image capture unit 51, barcode detection unit 52, target product determination unit 53, service label detection unit 54, notification unit 55, information). The module configuration includes an output unit 56, a target product switching unit 57, and a target product determination unit 58).
