Description

  The present invention relates to a merchandise data input device used for checkout operations such as in a supermarket.

  A product data input device that is used in a store such as a supermarket and can communicate with a POS (Point Of Sale) terminal is generally connected in a state where it can communicate with a POS terminal and a barcode reader that reads a barcode indicating a product. A touch panel that functions as a graphical user interface (GUI) of the POS terminal, and a keyboard having numeric keys, multiplication keys, subtotal keys, and current keys for inputting information related to barcode input Configured. The operator performs product registration work by causing a barcode reader included in the product data input device to sequentially read the barcodes attached to the products brought in by the customer. When the registration of all the products is completed, the operator presses a subtotal key provided on the keyboard to close the product registration work and perform the following accounting work (see Patent Document 1).

  When registering a product using such a product data input device, if there are multiple identical products, the operator registers the product using a multiplication key or a numeric key provided on the keyboard. There is a way. Specifically, the multiplication registration method includes a method of operating the keyboard in the order of the multiplication key and the numeric key after reading the barcode of the product, or the product after operating the keyboard in the order of the numeric key and the multiplication key. There is a method to read the barcode. Thereby, the conventional merchandise data input device reduces the burden on the operator when registering the same merchandise.

  However, the registration of multiple products using the multiplication keys and numeric keys provided on the keyboard forces the operator to perform operations that are far from normal registration work by reading barcodes. There is a problem of giving a burden. Specifically, during normal registration work by reading barcodes, the operator's line of sight is in the periphery of the product and the barcode reader, and the height of the hand of the operator holding the product is also high, centering on the window surface of the barcode reader. There is around. On the other hand, when operating the multiplication key or the numeric key provided on the keyboard, the operator's line of sight moves to the keyboard, and the height of the operator's hand must be moved to the height of the keyboard. Such an irregular operation has been a great psychological and physical burden on the operator who continues the registration work for a long time.

  The present invention has been made in view of the above, and an object of the present invention is to provide a product data input device that can reduce an operator's psychological and physical workload during registration work.

(First embodiment)
FIG. 1 is a perspective view showing an external appearance of a product data input apparatus according to the first embodiment of the present invention. FIG. 2 is a block diagram showing an internal configuration of the product data input apparatus according to the first embodiment of the present invention. As shown in FIGS. 1 and 2, the product data input device 100 according to the present embodiment includes an image recognition unit 101, a touch panel 102, a keyboard 103, and a hub 104. The image recognition unit 101, the touch panel 102, and the keyboard 103 are each connected to the hub 104 according to the USB (Universal Serial Bus) communication standard, and the host device such as an external POS (Point Of Sale) terminal (not shown) via the hub 104. Communication is possible.

  The touch panel 102 is connected to the external POS terminal via the hub 104 in a state capable of bidirectional communication, and functions as a GUI (Graphical User Interface) of the external POS terminal.

  The keyboard 103 includes a key for inputting related information related to input of product data indicating a product brought in by the customer. FIG. 3 is a diagram illustrating an example of keys provided on the keyboard. As shown in FIG. 3, the keyboard 103 is a key for inputting 11 types of numerical values, and a numeric key 109 and a multiplication key 110 for inputting related information such as the number of products for which product data is input. , A subtotal key 111, a deposit / cash key 112, and the like. When each key is pressed, a key code corresponding to each key is transmitted to the external POS terminal via the hub 104.

  In the present embodiment, as shown in FIG. 3, a keyboard 103 having only numeric keys 109 and multiplication keys 110 as keys for inputting related information will be described. The key is not limited to this. For example, the present invention can be applied to a keyboard provided with keys for inputting related information such as discounts on products and coupons.

  The image recognition unit 101 includes a CCD (Charge Coupled Device) camera 105, a barcode recognition unit 106, a finger sign recognition unit 107, and a speaker 108. The CCD camera 105 sequentially transfers an image obtained by photographing an operator's hand operating the product data input device 100 to the barcode recognition unit 106 and the finger sign recognition unit 107. The speaker 108 is controlled by the bar code recognition unit 106 or the finger sign recognition unit 107 and emits a notification sound.

  The bar code recognition unit 106 detects a bar code (optical symbol) attached to a product from the image transferred from the CCD camera 105, and decodes the detected bar code. Read code information (product data) (reading means). Then, the barcode recognition unit 106 transmits the read barcode information to the external POS terminal via the hub 104. In this embodiment, the barcode recognition unit 106 reads barcode information from an image taken by the CCD camera 105, but the present invention is not limited to this. For example, barcode information may be read by laser scanning.

  Further, the barcode recognition unit 106 is connected to the speaker 108 and emits a notification sound from the speaker 108 when barcode decoding is established (that is, when barcode information is read). Furthermore, the barcode recognition unit 106 is connected to the finger sign recognition unit 107 and transmits a reset signal to the finger sign recognition unit 107 when reading the barcode information.

  The finger sign recognition unit 107 detects the operator's hand included in the image transferred from the CCD camera 105. Then, the finger sign recognition unit 107 determines whether or not the detected finger sign (hand shape) of the hand is a finger sign corresponding to any of a plurality of pre-registered finger signs (determination means).

  In the present embodiment, the finger sign recognition unit 107 uses the image transferred from the CCD camera 105, and the finger sign included in the image corresponds to one of a plurality of finger signs registered in advance. Although it is determined whether it is a finger sign, it is not limited to this. Using an image photographed by another photographing means capable of photographing an image of a reading area obtained by reading the barcode information by the barcode recognition unit 106, a finger sign included in the image is a plurality of finger signs registered in advance. It may be determined whether or not the finger sign corresponds to any of the above.

  In the present embodiment, as shown in FIG. 4, the finger sign recognition unit 107 relates to the input of the barcode information that the finger sign included in the image transferred from the CCD camera 105 is read by the barcode recognition unit 106. Number mode (first mode) for determining whether or not a finger sign (number sign) representing a key code corresponding to a key for inputting related information (for example, numeric key 109 or multiplication key 110) And a normal mode (second mode) for determining whether or not a finger sign (trigger sign) indicating a transition to the number mode without determining whether or not the finger sign corresponds to a number sign registered in advance. ) Between the two operation modes. Here, the trigger sign and the number sign are any of the above-described finger signs, and each finger sign is registered in advance. FIG. 4 is an explanatory diagram showing mode transition between operation modes.

  Then, in the normal mode, the finger sign recognition unit 107 determines whether the detected finger sign of the hand is a finger sign corresponding to any of the pre-registered trigger signs, and the pre-registered trigger When it is determined that the finger sign corresponds to the sign, the mode transits to the number mode. When the finger sign recognition unit 107 is in the normal mode, it is determined only whether or not the finger sign corresponds to a trigger sign registered in advance.

  On the other hand, in the number mode, the finger sign recognition unit 107 determines whether the detected finger sign of the hand is a finger sign corresponding to any of the number signs registered in advance, and detects the finger of the detected hand. When it is determined that the sign is a finger sign corresponding to a number sign registered in advance, a key code represented by the finger sign corresponding to the number sign is transmitted to the external POS terminal via the hub 104 (transmission means) ). In the present embodiment, the finger sign recognition unit 107 uses finger characters used in sign language as number signs, but the present invention is not limited to this. In this embodiment, the barcode recognition unit 106 transmits the barcode information to the external POS terminal. However, the finger sign recognition unit 107 reads the barcode information read by the barcode recognition unit 106 together with the key code. May be transmitted to the external POS terminal.

  When the finger sign recognition unit 107 is in the number mode, it is determined only whether or not the finger sign corresponds to a number sign registered in advance. Also, the finger sign recognition unit 107 returns to the normal mode after a predetermined time has elapsed after receiving a reset signal from the barcode recognition unit 106 or determining that the finger sign is a trigger sign registered in advance. It shall be.

  FIG. 5 is a diagram showing a correspondence table between pre-registered finger signs and key codes. In the present embodiment, as shown in FIG. 5, the finger sign recognition unit 107 stores a correspondence table in which a pre-registered finger sign (trigger sign and number sign) model and a key code are associated with each other in advance. I remember it. The finger sign recognition unit 107 determines whether or not the detected finger sign of the hand is a finger sign corresponding to a trigger sign or number sign model included in the correspondence table shown in FIG. If it is determined that the finger sign corresponds to the trigger sign model, the finger sign recognition unit 107 transitions to the number mode. On the other hand, when it is determined that the finger sign corresponds to the number sign model, the finger sign recognition unit 107 displays the key code associated with the finger sign corresponding to the number sign model in the correspondence table shown in FIG. , To the external POS terminal via the hub 104.

  In addition, when the finger sign recognition unit 107 transmits a key code corresponding to the numeric key 109 and the multiplication key 110 for inputting the number of products to the external POS terminal, It is also possible to switch the transmission order of the key codes corresponding to.

  For example, when the finger sign recognition unit 107 determines that the detected finger sign of the hand is a number sign in a shape (finger sign) in which the index finger and the middle finger of the left hand are raised (finger sign), “2” that is the key code of the number key 109 and “×” that is the key code of the multiplication key 110 are transmitted in the order of “2” and “×”. Further, when the finger sign recognition unit 107 determines that the detected finger sign of the hand is a number sign in a shape (finger sign) in which the index finger, the middle finger, and the ring finger of the left hand are raised, it is associated with the number sign. In addition, “3” that is the key code of the numeric key 109 and “×” that is the key code of the multiplication key 110 are transmitted in the order of “3” and “×”. If the finger sign recognition unit 107 determines that the finger sign of the detected hand is a number sign of a shape (finger sign) in which the index finger and middle finger of the right hand are raised, the number associated with the number sign “2” that is the key code of the key 109 and “×” that is the key code of the multiplication key 110 are transmitted in the order of “×” and “2”.

  In the present embodiment, key codes corresponding to the numeric key 109 and the multiplication key 110 are transmitted as key codes corresponding to the keys for inputting the number of products. However, the present invention is not limited to this. For example, only the key code corresponding to the numeric key 109 may be transmitted as the key code corresponding to the key for inputting the number of products.

  Further, the finger sign recognition unit 107 is connected to the speaker 108 and emits a notification sound (output means). Specifically, when the finger sign recognition unit 107 determines that the finger sign of the detected hand is a finger sign corresponding to one of the pre-registered trigger signs, the notification that notifies the transition to the number mode. Sound A is emitted from the speaker 108. As a result, the operator can recognize that he has exited from the normal mode and has transitioned to the number mode.

  In addition, when the finger sign recognition unit 107 determines that the finger sign of the detected hand is a finger sign corresponding to one of the pre-registered number signs, the finger sign recognition unit 107 selects the finger sign corresponding to the pre-registered number sign. A corresponding notification sound C is emitted from the speaker 108. For example, the finger sign recognition unit 107 outputs the notification sound C from the speaker 108 by the number of products that can be registered by the key represented by the number sign, so that the operator recognizes that the multiplication processing has been performed correctly. Can do.

  Further, the finger sign recognition unit 107 receives a reset signal from the bar code recognition unit 106, or determines that the finger sign is a finger sign corresponding to a pre-registered trigger sign. Before the reading is performed, a notification sound B notifying the return to the normal mode is emitted from the speaker 108. As a result, the operator can recognize that he has exited the number mode and has returned to the normal mode. Note that the notification sound A, the notification sound B, the notification sound C, and the notification sound when the barcode decoding is established are different from each other.

  Next, an operation sequence for determining a finger sign in the finger sign recognition unit 107 will be described with reference to FIG. FIG. 6 is a flowchart showing a flow of processing for determining a finger sign.

  First, the finger sign recognition unit 107 acquires an image transferred from the CCD camera 105 (step S601). Next, the finger sign recognition unit 107 determines whether or not the finger sign included in the acquired image is a finger sign corresponding to a trigger sign registered in advance (step S602). When it is determined that the finger sign is not a trigger sign registered in advance (step S602: No), the finger sign recognition unit 107 returns to step S601 and acquires the image transferred from the CCD camera 105 again.

  Note that, as described above, the determination as to whether or not the finger sign corresponds to a trigger sign registered in advance is performed by comparison with a model of a trigger sign registered in advance. For comparison with a pre-registered trigger sign model, for example, high-speed object detection using Hear-like features used for facial image recognition and the like is used ("Paul Viola and Michael J. Jones. Rapid Object Detecting using a Boosted Cascade of Simple Features. "IEEE CVPR, 2001.").

  If the finger sign recognition unit 107 determines that the finger sign included in the acquired image is a finger sign corresponding to the trigger sign registered in advance (step S602: Yes), a timer for measuring a predetermined time is set. In addition to starting (step S603), the speaker 108 outputs a notification sound A notifying that the number mode has been changed (step S604). Note that the notification sound A is a sound different from the notification sound that is emitted when barcode decoding is established.

  Thereafter, the finger sign recognition unit 107 determines whether a reset signal has been received from the barcode recognition unit 106 (step S605). If it is determined that the reset signal has been received from the barcode recognition unit 106 as a result of the determination (step S605: Yes), the finger sign recognition unit 107 outputs a notification sound B notifying the return to the normal mode from the speaker 108. At the same time (step S611), the process returns to step S601 to acquire the image transferred from the CCD camera 105 again. The notification sound B is different from the notification sound and the notification sound A that are generated when the decoding of the barcode is established.

  If the finger sign recognition unit 107 determines that the reset signal has not been received from the barcode recognition unit 106 (step S605: No), whether the time measured by the timer started in step S603 has passed a predetermined time. Is determined (step S606). When the finger sign recognition unit 107 determines that the time measured by the timer has passed the predetermined time as a result of the determination (step S606: Yes), the notification signal B is output from the speaker 108 (step S611). Returning to step S601, the image transferred from the CCD camera 105 is acquired again.

  When it is determined that the time measured by the timer has not passed the predetermined time (step S606: No), the finger sign recognition unit 107 acquires a new image transferred from the CCD camera 105 (step S607). It is determined whether the finger sign included in the acquired image is a finger sign corresponding to a number sign registered in advance (step S608). Here, when the finger sign recognition unit 107 determines that the finger sign included in the acquired image is not a finger sign corresponding to the number sign registered in advance (step S608: No), the process returns to step S605. It is determined whether a reset signal has been received from the code recognition unit 106.

  If the finger sign recognition unit 107 determines that the finger sign included in the acquired image is a finger sign corresponding to a pre-registered number sign (step S608: Yes), the key code represented by the finger sign Is transmitted to the external POS terminal via the hub 104 (step S609), and the notification sound C corresponding to the finger sign is output from the speaker 108 (step S610). In the present embodiment, it is assumed that the finger sign recognition unit 107 outputs the notification sound C for the same number of times as the number of products that can be input by the key code represented by the number sign. Note that the notification sound C is a sound different from the notification sound, notification sound A, and notification sound B that are emitted when the barcode is decoded. In the present embodiment, the notification sound C is output the same number of times as the number of products that can be input by the key code represented by the number sign, but the present invention is not limited to this. For example, the finger sign recognizing unit 107 may output the sound of a word that conveys the number of products that can be input by the key code represented by the number sign as the notification sound C.

  Next, the usage status of the product data input device 100 according to the present embodiment will be described. The product data input device 100 is used for product registration / settlement of a supermarket or the like together with an external POS terminal. Product registration / settlement in the supermarket mainly comprises two steps, product registration business and settlement business, and the product data input device 100 is used for product registration business and not for settlement business.

  The operator of the product data input device 100 sequentially picks up the products brought in by the customer and presents the barcode printed or attached to the side of the product to the CCD camera 105 of the image recognition unit 101. The image recognition unit 101 reads the barcode information by the barcode recognition unit 106 and transmits the read barcode information to the external POS terminal via the hub 104. The external POS terminal that has received the barcode information performs barcode information processing such as registration of the product indicated by the received barcode information, and proceeds with the product registration work.

  Further, when a customer brings in a plurality of the same products, the operator performs a product registration work by one of the following methods.

  First, in the first method, the operator presents the left hand toward the CCD camera 105 of the image recognition unit 101 in the shape of a trigger sign. The image recognizing unit 101 determines whether or not the finger sign corresponds to the trigger sign registered in advance by the finger sign recognizing unit 107. If it is determined that the finger sign corresponds to the trigger sign, the image recognition unit 101 enters the number mode. A notification sound A that informs the transition is output. The operator who has recognized that the number mode has been entered changes the left hand into the shape of a number sign according to the number of products to be registered and presents it to the CCD camera 105 of the image recognition unit 101. When the image recognition unit 101 determines whether the finger sign corresponds to the number sign registered in advance by the finger sign recognition unit 107 and determines that the finger sign corresponds to the number sign registered in advance. Transmits the key code represented by the finger sign to the external POS terminal via the hub 104.

  Next, the operator presents the barcode printed or attached to the side of the product to be registered toward the CCD camera 105 of the image recognition unit 101. The image recognition unit 101 reads the barcode information by the barcode recognition unit 106 and transmits the read barcode information to the external POS terminal via the hub 104. The external POS terminal that has received the key code and the bar code information performs bar code information processing such as a product registration process indicated by the bar code information in accordance with the key code.

  In the second method, the operator presents the barcode printed or attached to the side surface of the registration target product toward the CCD camera 105 of the image recognition unit 101. The image recognition unit 101 reads the barcode information by the barcode recognition unit 106 and transmits the read barcode information to the external POS terminal via the hub 104.

  Next, the operator presents the right hand in the shape of a trigger sign toward the CCD camera 105 of the image recognition unit 101. When the image recognizing unit 101 determines whether the finger sign corresponds to the trigger sign registered in advance by the finger sign recognizing unit 107 and determines that the finger sign corresponds to the pre-registered trigger sign. Outputs a notification sound A notifying that the mode has been changed to the number mode. The operator who has recognized that the user has entered the number mode changes the right hand into a number sign shape according to the number of products to be registered, and presents it to the CCD camera 105 of the image recognition unit 101. When the image recognition unit 101 determines whether the finger sign corresponds to the number sign registered in advance by the finger sign recognition unit 107 and determines that the finger sign corresponds to the number sign registered in advance. Transmits the key code represented by the finger sign to the external POS terminal via the hub 104. The external POS terminal that has received the barcode information and the key code performs barcode information processing such as registration processing of a product indicated by the barcode information in accordance with the key code.

  As described above, according to the product data input apparatus 100 according to the present embodiment, the barcode information is read from the image acquired from the CCD camera 105, and the read barcode information is transmitted to the external POS terminal via the hub 104. Then, it is determined whether the finger sign included in the image acquired from the CCD camera 105 is a finger sign corresponding to a pre-registered number sign, and is a finger sign corresponding to a pre-registered number sign. When the determination is made, the key code represented by the finger sign is transmitted to the external POS terminal via the hub 104, so that the operator registers the product without moving the line of sight and the work range of the hand greatly when registering the product. So that the psychological and physical nature of the operator during registration It is possible to reduce the work burden. The operator can execute an operation of registering a plurality of the same products without greatly changing the operation from the normal registration operation. Further, by outputting a notification sound informing the number of registered products, the operator can confirm that the registration work can be performed without greatly changing the operation from the normal registration work.

(Second Embodiment)
In the present embodiment, the read barcode information is transmitted to an external POS terminal in accordance with a command indicated by a finger sign. In addition, description of a location similar to 1st Embodiment is abbreviate | omitted, and only a location different from 1st Embodiment is demonstrated.

  FIG. 7 is a block diagram showing an internal configuration of the product data input apparatus according to the present embodiment. As shown in FIG. 7, the product data input device 700 according to the present embodiment is a first implementation in that a barcode recognition unit 701 and a finger sign recognition unit 702 are connected in a state where bidirectional communication is possible. This is different from the product data input device 100 according to the embodiment.

  The finger sign recognition unit 702 receives a reset signal from the barcode recognition unit 701 and then detects the finger signature of the hand detected from the image acquired from the CCD camera 105 as a pre-registered finger sign. It is determined whether or not the finger sign corresponds to a finger sign (number sign) representing a multiplication command corresponding to a key (for example, numeric key 109, multiplication key 110, etc.) for inputting related information related to the input. (Determination means) When the finger sign recognition unit 702 determines that the finger sign of the hand detected from the image acquired from the CCD camera 105 is a finger sign corresponding to a pre-registered number sign, the multiplication represented by the finger sign A command (for example, a multiplication command that includes front and rear information indicating whether the timing at which the barcode information is read before or after the timing at which the barcode information is determined to be a pre-registered number sign) ) Is transmitted to the barcode recognition unit 701. Note that the finger sign recognition unit 702 is not directly connected to the hub 104.

  When the barcode recognition unit 701 reads the barcode information, the barcode recognition unit 701 transmits a reset signal to the finger sign recognition unit 702 and receives a command such as a multiplication command from the finger sign recognition unit 702. Then, the barcode recognition unit 701 transmits the barcode information decoded immediately before or after the received multiplication command to the external POS terminal a plurality of times via the hub 104 (transmission means). At that time, it is assumed that the barcode recognition unit 701 emits a notification sound from the speaker 108 according to the number of barcode information to be transmitted.

  More specifically, when the preceding and following information included in the received multiplication command is “front”, the barcode recognition unit 701 includes the barcode information read immediately before in the received multiplication command. The number of times obtained by subtracting 1 from the multiplication number is transmitted to the external POS terminal via the hub 104. On the other hand, when the front and rear information included in the received multiplication command is “after”, the barcode recognition unit 701 converts the barcode information read immediately after the received multiplication command into the number of multiplications included in the received multiplication command, the hub The data is transmitted to the external POS terminal via 104. Here, when the preceding and following information is “Previous”, 1 is subtracted from the multiplication number. When the barcode recognition unit 701 receives the multiplication command, the barcode information read immediately before is already once. This is because the data is transmitted to the external POS terminal via the hub 104.

  In the present embodiment, when the front / rear information is “previous”, the barcode recognition unit 701 transmits the barcode information by the number of times obtained by subtracting 1 from the multiplication number. However, the present invention is not limited to this. . For example, when the preceding and following information is “Previous”, the finger sign recognition unit 702 may transmit a multiplication command including a numerical value obtained by subtracting 1 from the multiplication number to the barcode recognition unit 701 in advance.

  In this embodiment, the barcode information is transmitted to the external POS terminal a plurality of times according to the multiplication command. However, the present invention is not limited to this as long as the barcode information is transmitted according to the command. For example, when the barcode recognition unit 701 receives a command indicating a product discount or a coupon, the barcode recognition unit 701 may transmit information such as a discount or a coupon indicated by the received command to the external POS terminal together with the barcode information.

  Next, an operation sequence for determining a finger sign in the finger sign recognition unit 702 will be described with reference to FIG. FIG. 8 is a flowchart showing a flow of processing for determining a finger sign. Steps S801 to S808 and S810 are the same as steps S601 to S608 and S611 shown in FIG.

  When the finger sign recognition unit 702 determines that the finger sign of the hand detected from the image acquired from the CCD camera 105 is a finger sign corresponding to a pre-registered number sign (step S808: Yes), barcode recognition is performed. A multiplication command is transmitted to the unit 701 (step S809). In the present embodiment, the notification sound C for notifying the multiplication number corresponding to the number sign is not emitted. Therefore, in this embodiment, the barcode recognition unit 701 decodes the barcode each time it transmits the barcode information to the external POS terminal via the hub 104 according to the multiplication number included in the multiplication command. A notification sound is generated when it is established.

  As described above, according to the product data input device 700 according to the present embodiment, the read barcode information is transmitted to the external POS terminal in accordance with the command indicated by the number sign, so that the product data input according to the first embodiment is performed. The same effects as the device 100 can be obtained.

  It should be noted that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
