FIG. 2 is a perspective view showing an example of the product sales data processing device 100. FIG. 3 is an electrical functional block diagram of the product sales data processing device 100.

  In the present embodiment, a case where the product sales data processing device 100 is applied to a self-type weighing device will be described. The merchandise sales data processing apparatus 100 is installed in a store such as a supermarket, generates sales data such as the type and amount of the merchandise in which articles are stored in containers, and transmits the sales data to a cash register, a host computer, or the like. You can register. Further, the product sales data processing apparatus 100 includes a printing unit 9 such as a printer, and the printing unit 9 can issue a label according to sales data. This store sells salads and other items sold by weight and croquettes and other items sold by quantity.

The merchandise sales data processing apparatus 100 (self-type weighing device) according to the embodiment of the present invention does not require an operator (customer) to perform an operation input for specifying whether the sales mode is a weighing or piece-selling sales mode. When a product is placed on a weighing dish or the like of the weighing unit 7 of the apparatus, it is automatically determined whether the sales mode is a weighed-for-sale product or a quantity-sold product, and sales data of the product is generated. . Further, the merchandise sales data processing device 100 issues a label printed with information according to the sales form of the merchandise. The customer affixes the label to the container and pays a predetermined amount at the place where the cash register is installed.
Hereinafter, each component of the product sales data processing device 100 (self-type weighing device) will be described in detail.

  The product sales data processing device 100 according to the embodiment of the present invention includes a control unit 1 (CPU), a ROM 2 and a RAM 3 as storage units (storage units), an auxiliary storage unit 4, an operation unit 5, a display unit 6 , A weighing unit 7, an imaging unit 8, a printing unit 9, a communication unit 10, an audio output unit 11 (speaker), and the like. The above components are electrically connected by a communication line 12 such as a bus (see FIG. 3 and the like).

As shown in FIGS. 1 and 2, a weighing unit 7 having a weighing dish (not shown) and the like is provided in the apparatus main body 100 a of the product sales data processing apparatus 100. A printing section 9 such as a printer is provided in the apparatus main body 100a, and a label issued by the printing section 9 is discharged from a paper discharge port 9a.
An operation unit 5, a display unit 6, and the like, which are supported by a support unit 100b, are provided at an upper portion of the apparatus main body 100a. In the present embodiment, a touch panel device is employed as the operation unit 5 and the display unit 6. An image pickup unit 8 for picking up an image of a product (container) placed on a weighing dish (placement unit (placement means)) of the weighing unit 7 is provided on the operation unit 5, the display unit 6, or the support unit 100b. Have been. An imaging range 80 (recognition range) of the imaging unit 8 is set on the weighing unit 7 (see FIG. 2).
When the imaging unit 8 captures an image of a product (container) placed on a weighing plate (mounting unit) of the weighing unit 7, light is reflected on the weighing plate (mounting unit) of the weighing unit 7. From the captured image of the product (container) including the background composed of the weighing dish (mounting portion) of the weighing unit 7 captured by light, the shape and color of the product (container) or the attached material attached to the container May not be recognized correctly.
In order to avoid such a state, for example, there is a method of baking or frosting the weighing plate (mounting portion) of the weighing unit 7 in black, but it is not possible to completely prevent the reflection of light. .
Therefore, as a method of completely preventing the reflection of light (or a method of reducing the reflection of light), a method of raising the measuring dish (mounting section) of the measuring section 7 with black brushed at a predetermined density is adopted. More specifically, electrostatic flocking and flocking coating are performed as a method for raising the measuring dish (mounting section) of the measuring section 7 with a predetermined density of black.
Accordingly, the reflection of light can be completely prevented with respect to the weighing plate (mounting portion) of the weighing unit 7, so that it is possible to correctly recognize the shape and color of the product (container) from the captured image. . In addition, when a sticker with identification information for identifying the container is attached to the container (for example, the sticker is a sticker made of a graphic or a label on which code information is printed), the sticker is also attached. The attached material can be correctly recognized.
It is also effective for a transparent container, and the shape and color of a product (transparent container) can be correctly recognized from a captured image.
Further, in addition to electrostatic flocking and flocking coating, for example, the reflection of light can be prevented by wrapping or covering the weighing dish (mounting portion) of the weighing section 7 with a sponge or cloth such as black which is hard to reflect. It is possible.
In addition, at least a region where the measuring plate (mounting portion) of the measuring portion 7 is blackened with a predetermined density by electrostatic flocking or flocking coating is mounted on the measuring plate (mounting portion) of the measuring portion 7. This is an area where the placed product (container) is imaged. Further, a material other than the region where the black raising is performed may be made of a different material (for example, a normal plated state, or a baking coating or a matte coating). As a result, since the texture is different between the black-brushed region and the other region imaged by the imaging unit 8, where the customer places the container on the weighing dish (mounting unit), It is easy to understand whether it is good or not, and the container is not placed in a place where the image can not be picked up by the image pickup unit 8. Thus, the container can be correctly recognized and specified from the captured image data.

  The control unit 1 (CPU) controls each component of the merchandise sales data processing device 100 as a whole.

  The weighing unit 7 has a weighing pan (mounting unit) and the like, weighs the mass of an article or the like placed on the weighing pan or the like, and outputs information indicating mass data of the article or the like to the control unit 1.

The imaging unit 8 captures an image of the container. In the present embodiment, an image of a container containing an article as a product placed in an imaging range 80 (recognition range) on the weighing unit 7 is captured and output to the control unit 1. Examples of the imaging unit 8 include a CCD imaging device and a CMOS imaging device.
Note that a light emitting unit such as a light that illuminates the imaging range 80 (recognition range) of the measuring unit 7 may be provided near the imaging unit 8.

  Under the control of the control unit 1, the printing unit 9 prints, on a label, sales data (such as the type and amount of the product) of the product in which the article is stored in the container.

  The communication unit 10 can perform data communication with a computer such as a cash register or a host computer via a wired or wireless communication path under the control of the control unit 1.

  The sound output unit 11 (speaker) can emit a sound such as an operation guide and an error sound for the product sales data processing device 100 (self-type weighing device) at a predetermined timing under the control of the control unit 1.

  As described above, the control unit 1 (CPU) causes the product sales data processing device 100 as a computer to realize the functions according to the present invention by executing the control program stored in the storage unit. As shown in FIG. 3, the control unit 1 includes a container determination unit 101 (container determination unit), a product registration unit 102 (product registration unit), and the like.

  The container determining unit 101 specifies the container imaged by the image capturing unit 8 based on the image data of the container imaged by the image capturing unit 8 and the specific information that specifies the container. It is determined whether or not the sale is by weight, specifically, whether the sale is by weight or by quantity.

When the sales form of the container specified by the container determination unit 101 is a product to be sold by weighing, the product registration unit 102 generates sales data of the product based on the mass data of the article or the like measured by the measuring unit 7. And register.

In addition, the product registration unit 102 performs a process of generating and registering sales data based on the unit price of the article and the mass data obtained by subtracting the mass data of the container from the mass data of the container containing the articles measured by the measuring unit 7. .

  Further, in the container identification process performed by the container determination unit 101, the control unit 1 uses the container identification information stored in the container information storage unit 32 and the container of the product imaged by the imaging unit 8 in the identification information that identifies the container. If the information corresponding to is not included, a process of displaying a plurality of container type candidates stored in a storage unit such as the RAM 3 in a selectable manner on the touch panel display unit 6 is performed.

  FIG. 4 is a diagram showing an example of information stored in the RAM 3 or the like as a storage unit of the product sales data processing device 100. 4A is a diagram illustrating an example of product information, and FIG. 4B is a diagram illustrating an example of container information.

Product information (product information) is stored in association with product classification, product code (product code), product names such as croquettes and salads, production locations, unit weights (unit mass data), standard units, container codes, unit prices, etc. doing.
In the case where an article (article) is specified by image data (image data) obtained by imaging the article (article) by the imaging unit 8 (imaging means), the article information includes the article specifying information (the article specifying information is (Data obtained by digitizing the size, color, shape, etc. of the product).

  Container information includes container code, container name (container type) such as rectangular container and round container, container identification information (specific information), sales form information, product code (article code), container mass data (tare weight data) , Or tare mass data). The container identification information is information indicating the area of the container (the area of the container when the image is taken by the imaging unit 8), the shape of the container, and the like. The information indicating the shape and the like of the container is not limited to the shape, area, color, and the like when the container is imaged from above. For example, the imaging unit 8 (imaging means) images the bottom of an article (product) and obtains image data. When (image data) is obtained, the shape of the bottom of the container, the area of the bottom, the color of the bottom, and the like become container specifying information (specific information), and the imaging direction of the imaging unit 8 (imaging means) is set to the side end of the container. In the case of (front, rear, left and right), the shape of the side end of the container, the area of the side end, the color of the side end, and the like are the container specifying information (specific information). As the sales form information, for example, it is indicated by 0 in the case of unit sales, and is indicated by 1 in the case of mass sales. That is, the sales form information indicates whether or not the sales form of the container is weighing sales. The setting of the container specifying information is performed on the setting screen, and the imaging unit 8 captures an image of the empty container placed on the placement unit of the weighing unit 7, performs binarization processing, and acquires the area of the container. The obtained area is stored in a storage unit such as the RAM 3 as container specification information (specific information) of the container. In addition, the container specifying information is not limited to the area, and may be, for example, the number of binarized dots of the container, or the external shape (silhouette), the actual three-dimensional dimensions (length, width, height). It may be a combination of colors and patterns on the surface of the container.

  In the present embodiment, the type of container (tray) and the type of article stored in the container (tray) are stored in the storage unit in association with each other. Further, the type of the container (tray) and the sales form information are stored in the storage unit in association with each other.

  FIG. 5 is a diagram showing an example of a setting screen by the product sales data processing device 100. In detail, an example of a screen for setting information on a container such as a tray (container) size is shown.

The setting screen is obtained by performing a binarization process on the capture button 60, an image of the product or the like captured by the imaging unit (capture image 61), and the image (capture image 61) based on the set threshold. The obtained binarized image (converted image 62), a plurality of operation buttons 63 for setting a threshold for binarization processing, a threshold display section 64 for displaying a threshold, and a plurality of operation buttons for setting a protruding threshold 65, an overflow threshold display section 66 for displaying an overflow threshold, a tray size display section 67 for indicating the size of a tray (container), a setting button 68 for setting the size of a tray (container), and an end button for ending the setting 69, and the like.
The tray size display section 67 displays the number of pixels or the area of the tray (container) in the portion (white portion in FIG. 5) corresponding to the tray (container) in the binarized image (converted image 62). .

  By operating the up button 63u or the down button 63d related to the binarization processing, the threshold value of the binarization processing can be finely adjusted manually. When the automatic setting button 63a for automatically setting the threshold value of the binarization process is operated, a specified threshold value is set based on the illuminance (luminance) of the surrounding environment.

  By operating the up button 65u or the down button 65d related to the protruding threshold, the protruding threshold can be finely adjusted manually. When the automatic setting button 65a for automatically setting the protruding threshold is operated, a specified protruding threshold is set based on the illuminance (luminance) of the surrounding environment.

When the capture button 60 is operated, a captured image 61 of a container or the like captured by the imaging unit is displayed, and a binarization obtained by performing a binarization process on the captured image 61 based on the set monochrome threshold value. The image (the converted image 62) is displayed.
Then, the number of pixels of the portion (white portion in FIG. 5) corresponding to the tray (container) or the area (container identification information) of the tray (container) is displayed on the tray size display section 67.
When the setting button 68 is operated, the area of the tray (container) displayed on the tray size display section 67 and the type of the set tray (container) are stored in a storage unit such as the RAM 3 in association with each other. You.

  As shown in FIG. 5, a product recognition range 61a is set in the image (capture image 61). It is preferable that the recognition range 61a is set to correspond to, for example, an edge of a weighing dish of the weighing unit. The control unit determines that the container of the product cannot be accurately specified, such as when the product protrudes from the recognition range 61a or when the operator's hand or the like appears in the captured image 61, and performs error processing. Examples of the error processing by the control unit include a process of displaying an error on the display unit and a process of displaying on the display unit a display prompting the user to place a product in the recognition range 61a.

  Specifically, in the present embodiment, a plurality of protrusion detection units 61c are provided around the recognition range 61a. When the pixel value of the protrusion detection unit 61c is equal to or larger than the threshold value, the control unit 1 determines that an error has occurred, such as a product protruding from the recognition range 61a, an operator's hand or the like being captured in the captured image 61, or the like. And performs error processing.

  When the pixel value of the protrusion detection unit 61c is equal to or larger than the threshold, the control unit 1 determines that there is an error and performs error processing. As the error processing, a container selection screen is displayed on the display unit. Processing may be performed. On the container selection screen, images indicating the types of the plurality of containers stored in the storage unit are displayed. The operator (user or the like) looks at the container selection screen displayed on the display unit and selects the same type of container as the actual one. The control unit 1 performs a process of specifying a container based on a signal input from the operation unit. By doing so, even in the case of an error in the image recognition processing, the control unit 1 can easily specify the container based on the signal from the operation unit.

  When an error is detected by a plurality of protrusion detection units 61c, and when the number of “protrusion detection units 61c” less than a threshold is less than a predetermined number, the control unit 1 may determine an error. By doing so, the accuracy of error detection can be improved.

  In addition, since the hand is actually judged as a part of the container, the area of the container (for example, the total number of dots) may happen to coincide with another container. The protruding detection unit 61c is provided because there is a possibility that processing will be performed based on judgment.

  The control unit 1 performs an error process when the protrusion detection unit 61c cannot be detected. For example, when a seal (specific information) that specifies a sales mode of the container is detected in the imaging data, the control unit 1 Alternatively, it may be determined from the seal (specific information) whether the product is sold by weighing or sold by quantity, and a container selection screen may be displayed. It is to be noted that the container (product) placed on the placing portion is a product sold by weighing only with a sticker (specific information) for specifying the sales form attached to the container, not limited to the case where the protrusion detection unit 61c cannot be detected. It may be determined whether or not this is the case. In this case, the sticker that specifies the sales form attached to the container may be, for example, a seal made of a figure that specifies the sales form, a label on which code information that specifies the sales form is printed, or the like. Further, the sticker for specifying the sales form attached to the container may be attached to any location of the container as long as the location allows imaging.

  In step S101, the control unit 1 determines whether or not an article stored in a container is placed on a weighing dish or the like of the weighing unit 7 based on a signal from the weighing unit 7, and determines that the article is placed. If so, the process proceeds to step S102, and if no article is placed, the process in step S101 is repeated.

  In step S102, the mass of the article is measured by the measuring section 7, and the control section 1 receives information (mass data) indicating the mass of the article from the measuring section 7.

  In step S103, the control unit 1 performs a process of causing the imaging unit 8 to image a container placed on a weighing dish or the like of the weighing unit 7, receives imaging data (image data) of the container from the imaging unit 8, and Then, a process of storing the information in the storage unit is performed. After storing the imaging data (image data) in the storage unit, in the process of the next step S104, when specifying the container, the imaging data (image data) stored in the storage unit is read, and the read imaging data is read. The data may be binarized to obtain the area of the container (identification information), or in step S103, the imaging data (image data) of the container may be binarized to obtain the area of the container (identification information). May be acquired, and the acquired area (identification information) of the container may be stored in a storage unit such as the RAM 3 (acquisition unit).

  In step S104, the control unit 1 performs a container determination process (container identification process) based on the imaging data from the imaging unit 8. Specifically, the container determination unit 101 binarizes the image data of the container imaged by the imaging unit 8 and acquires the area (identification information) of the container (acquisition unit). That is, the acquiring unit acquires the identification information for identifying the container from the container. Then, based on the area (identification information) of the container obtained by binarizing the image data and the specific information for specifying the container stored in the container information storage unit 32, the imaged container is specified ( Determination means). In the present embodiment, the container determination unit 101 performs a process of specifying a container based on the size (area) of the tray (container) obtained from the binarized image data. Note that the container may be specified by the number of dots of the binarized image data, or may be specified by an appearance shape or the like (identification information or specific information). In this case, the information specifying the container stored in the container information storage unit 32 includes information on the external shape of the container (contour shape, dimensional information (length, width, height)), color and pattern on the surface of the container, and the like. May be stored. Further, a combination of the various types of information may be stored.

  In step S105, the control unit 1 determines whether or not the container has been specified. If the container has been specified, the process proceeds to step S108. If the container has not been specified, the process proceeds to step S106.

  In step S106, the control unit 1 performs a process of displaying a plurality of containers stored in a storage unit (storage unit) such as the RAM 3 on the display unit 6 as selectable candidates. More specifically, the control unit 1 performs a process of displaying image data and illustrations of the container corresponding to the container information on the display unit 6.

  In step S107, the control unit 1 determines whether or not a container has been selected by the operator (such as a customer). If a container has been selected, the process proceeds to step S108. If a container has not been selected, the process proceeds to step S108. Proceed to step S106.

  In step S108, the control unit 1 calls (reads) container information and product information from a storage unit such as the RAM 3.

  In step S109, the control unit 1 determines whether or not the product associated with the container is a weigh-selling product. If the product is a weigh-selling product, the process proceeds to step S111; otherwise, the process of step S110. Proceed to.

  In step S110, the control unit 1 generates sales data of unit sale, and proceeds to the process of step S112. In addition, the sales data of the quantity sale is calculated by calculating the number of articles based on the mass data obtained by subtracting the mass data of the container from the measured mass data of the goods and the unit mass data of the article, and calculating the calculated number and the article. The sales data of the product is generated based on the unit price of. If the product does not contain a plurality of products in a container, the sales data of the product is generated based on the unit price of the product without using the measured mass of the product.

  In step S111, the control unit 1 generates sales data for weighing sale, and proceeds to the processing in step S112. The sales data generation of the weighing sale generates the sales data of the merchandise based on the mass data obtained by subtracting the mass data of the container from the measured mass data of the merchandise and the unit price of the article.

  In step S112, the control unit 1 causes the printing unit 9 to perform a printing process according to the sales data, and performs a process of issuing a label. It should be noted that the label to be issued uses a mountless label, and the label whose label issuing direction is variable based on the print data amount according to the product is cut and issued after printing.

In step S113, the control unit 1 performs a process of registering sales data. More specifically, the control unit 1 performs a process of storing sales data in a storage unit such as the RAM 3, a process of registering the sales data in a cash register or a host computer via the communication unit 10, and the like.

In the case where the merchandise sales data processing device 100 is a self-contained weighing scale device having an accounting settlement function (payment settlement function), the merchandise sales data processing device 100 performs settlement for the goods purchased by the customer himself (self accounting settlement). ) May be performed.

  In the above-described embodiment, the type of the container is specified based on the image data (image data) captured by the image capturing unit 8, and based on the type of the container, the content is previously associated with the type of the container. Although the type and sales form of a certain article (commodity) are specified, the present invention is not limited to this form. For example, the type of an article such as a croquette or a horse mackerel may be specified based on image data (image data) captured by the image capturing section 8. In the embodiment, the container mounted on the mounting unit is imaged from above. However, the present invention is not limited to this. For example, the imaging unit 8 (imaging unit) images the bottom of the article (product) and obtains image data. (Image data) may be obtained, or the imaging direction of the imaging unit 8 (imaging means) may be the side end (both front and rear, left and right) of the container. In this case, when the imaging direction of the imaging unit 8 (imaging means) is from the bottom of the container, the container specification information (specific information) for specifying the container includes the shape of the bottom of the container, the area of the bottom, the color of the bottom, and the like. The container specifying information (specific information) becomes container specifying information (specific information), and when the imaging direction of the imaging unit 8 (imaging means) is the side end (front and rear, left and right) of the container, the container specifying information (specific information) for specifying the container is the container The shape of the side end, the area of the side end, the color of the side end, and the like are container specification information (specific information).

Next, a specific example of the embodiment of the present invention will be described.
FIG. 10 is a diagram for explaining an example of the specific information. More specifically, FIG. 10A is a diagram illustrating an example of the seal 70 (70 a, 70 b, 70 c) having the color and shape defined as the specific information. FIG. 10B is a diagram illustrating an example of a container 75 to which a seal 70b is attached as specific information, and FIG. 10C is a diagram illustrating an example of a container 75 to which a seal 70c is attached as specific information.

  In the above-described embodiment, the specific information for specifying the container stored in the storage unit is the area of the container (such as the number of dots corresponding to the area of the container), but is not limited to this mode. The specific information may be, for example, the shape and color of the seal 70 as shown in FIG. Further, it may be a label or the like on which code information (for example, a one-dimensional code or a two-dimensional code, etc.) specifying the sales form is printed.

The color of the colored portion of the seal 70 is, for example, a predetermined color such as red, blue, yellow, or green, and is defined by a hue, a color number, or the like. As the shape of the colored portion of the figure of the seal 70, for example, a square, a circle, a triangle, a polygon, or the like can be adopted.
The seal 70 has a colored portion of the figure and a white area (white portion) surrounding the colored portion at a predetermined distance outward. By providing the white portion, the color of the product and the color of the colored portion of the seal 70 can be easily distinguished, and the color shape of the distinguished seal 70 can be easily specified. The seal 70 attached to this container is attached, for example, by a clerk.

The specific information preliminarily defines the shape and color of the seal corresponding to the commodity for sale by mass and the commodity for sale by quantity, and stores them in the storage means in association with each other. A seal 70 indicating specific information is attached to the container 75. The control unit determines whether the product is sold by weighing or sold by quantity based on the shape of the seal 70 imaged by the imaging unit or the color of the seal 70.
By doing so, even when the container for the sold-by-quantity product and the container for the sold-by-quantity product have the same shape and area, the control unit determines the shape and color of the seal 70 as the specific information captured by the imaging unit. In addition, it is possible to easily determine whether the container is a container for a commodity for sale by weight or a container for a commodity for sale by quantity. In the case of a label or the like on which code information (for example, a one-dimensional code or a two-dimensional code) for specifying a sales form is printed, the label is printed on a label attached to a container of image data captured by the imaging unit. The code information for specifying the sales form is decoded to obtain the specific information (acquisition means). In the case of a one-dimensional code, a scanner device (scanner unit) may be used instead of the imaging unit 8 without using the imaging unit 8. Further, the product sales data processing device may be a device in which the imaging unit 8 and the scanner device are combined.

Next, another specific example of the embodiment of the present invention will be described.
The storage unit stores, for example, specific information A1 for specifying the container, specific information A2 for specifying the container, specific information A3 for specifying the container, and the like. The specific information A1, A2, and A3 are stored in the storage unit in association with information indicating whether the product is a sold-by-quantity product or a sold-by-quantity product.

The specification information A1 for specifying the container stores the area of the container, the number of dots corresponding to the area of the container, the shape of the container, and the like.
The specific information A2 for specifying the container stores information on the seal, for example, the shape of the seal, the color of the seal, and the like.
The specific information A3 for specifying the container stores, for example, only the color of the seal. In this example, as described above, the information relating to the area and shape of the container and the information relating to the seal are stored in the storage means in separate files.

Next, an example of a procedure performed by the control unit to determine whether the container is a weigh-selling item or a number-selling item will be described.
(I) First, the area of the container is determined. (II) It is determined whether or not a seal is attached. (III) When a seal is attached, after determining the shape of the seal, (IV) determining the color of the seal.
The control unit determines, for example, whether the container is a commodity sold by weighing or a commodity sold by quantity in the above-described procedure.

  Note that the procedure for determining whether a container is a weigh-selling item or a number-selling item is not limited to the above-described example. For example, an order (priority order) for determining whether a container is a weigh-selling item or a number-selling item for a container is set by the setting unit, and the control unit performs the above-described determination based on the priority set by the setting unit. Good.

  Next, an example of the priority order set by the setting means will be described.

“Specific information A1 specifying container” = third priority,
“Specific information A2 specifying container” = first priority,
“Specific information A3 specifying the container” = second priority,
“Specific information A4 specifying the container” = fourth priority.

  In this example, based on the specific information A1 for specifying the container, judging whether the container is a weighing sale item or a unit sale item based on the area of the container or the like is the third priority, and the specific information A2 for specifying the container. Based on the shape of the seal, it is the first priority to determine whether the container is a product sold by weighing or a product sold by quantity. Based on the specific information A3 for specifying the container, the container is weighed and sold by the color of the seal. Determining whether a product is a commodity or a quantity-selling product is the second priority, and code information (for example, a one-dimensional code or a two-dimensional code) that specifies a sales form is based on the specific information A4 that specifies a container. It is the fourth priority to determine whether a container is a weigh-selling item or a number-selling item based on the printed label.

  In addition, the control unit may determine whether the commodity is a weigh-selling item or a number-selling item based on a combination of the shape and the color of the sticker based on the captured image data. In this case, even if the type of the container is small, it is possible to increase the types of sales forms of the product by combining the type of the container and the color and shape of the seal. For this reason, the stock quantity and cost of the container can be reduced. When the sales form of a product (container) is determined by a label printed with a combination of the color and shape of the seal and code information (for example, a one-dimensional code or a two-dimensional code) for specifying the sales form, The location of the sticker or label to be affixed (or pre-printed) on the container is not limited to the top surface of the container, but may be any of the front and rear surfaces, the left and right surfaces, and the bottom surface. An image is provided from a corresponding direction.

As described above, the merchandise sales data processing apparatus 100 according to the embodiment of the present invention registers sales data of articles stored in containers.
Specifically, the merchandise sales data processing apparatus 100 includes an acquiring unit (an imaging unit 8 (imaging unit) for imaging the container) for acquiring identification information for identifying the container from the container, and a weighing unit for measuring the mass of the article. A storage unit (RAM3 or the like) that indicates whether or not the sales form of the container is weighing sales and stores specific information for specifying the container, a control unit 1 (CPU), and the like. . The control unit 1 specifies the container imaged by the imaging unit 8 based on the imaging data (image data) of the container imaged by the imaging unit 8 (imaging unit) and the specific information, and sells the container using the specified container. It has a container determining unit 101 (container determining means) for determining whether or not the form is weighing sale.
As described above, the container determination unit 101 of the product sales data processing apparatus 100 can determine whether the sales mode of the container imaged by the imaging unit 8 is weighing sale. Input and operation errors can be eliminated.

  In addition, the control unit 1 of the product sales data processing apparatus 100, when the sales form of the container specified by the container determination unit 101 (container determination unit) is the weighing sale, adds the mass data of the product measured by the measurement unit 7 A product registration unit 102 (product registration means) for generating and registering sales data of the product based on the product data;

  In detail, the merchandise sales data processing apparatus 100 specifies a container based on the image data (image data) imaged by the imaging unit 8 to determine whether the merchandise is a weigh-selling item or a number-selling item. It is specified whether the imaged container is sold by weight or sold by quantity. Then, based on the mass data of the product weighed by the weighing unit 7, the specified container can generate and register sales data in accordance with one of the sales modes of weighing sales or piece sales. . For this reason, it is not necessary for the operator to perform an operation input for specifying whether the sales form is weighed or sold separately, and it is possible to provide the product sales data processing apparatus 100 capable of reliably generating sales data. Further, as described above, it is possible to provide the commodity sales data processing apparatus 100 which can realize the effects according to the present invention with a simple structure.

  In addition, a storage unit such as the RAM 3 stores a container for accommodating articles in association with information (sales form) indicating whether the container is sold by mass or sold by quantity. At the time of setting, by associating in advance the information indicating the sales form with the number of types of containers in association with the types of containers and storing them in the storage unit, these can be easily set, and setting errors are small.

Further, in the embodiment of the present invention, when the container determining unit 101 cannot specify the container of the product imaged by the imaging unit 8 in the specifying process of the container housing the article, the storage unit such as the RAM 3 The merchandise sales data processing apparatus 100 includes a display unit 6 that displays one or more containers to be stored as candidates.
That is, when the container cannot be determined by the container determination unit, the display unit 6 (display unit) that displays the container stored in the storage unit such as the RAM 3 as a storage unit as a candidate is provided by the merchandise sales data processing apparatus. 100 have.
That is, even if the container cannot be recognized from the image data (image data) of the product imaged by the imaging unit 8, the control unit 1 displays a plurality of container type candidates on the display unit 6 so as to be selectable. Processing is performed, and the product registration unit 102 can reliably generate and register product sales data based on information indicating the type of container selected and input by the operator among the plurality of candidates.
In the process in which the control unit 1 displays the plurality of container type candidates on the display unit 6 in a selectable manner, the order in which the container type candidates to be displayed are displayed in the order in which the imaging data of the product imaged by the imaging unit 8 is displayed. Containers close to containers recognized based on (image data) may be displayed on the display unit 6 in a selectable order.

  Further, in the embodiment of the present invention, the container information storage unit 32 stores the mass data of the container. The merchandise registration unit 102 subtracts the mass data of the container from the mass data of the merchandise weighed by the weighing unit 7, and generates and registers sales data of the article based on the subtracted value. For this reason, it is possible to provide the product sales data processing apparatus 100 capable of appropriately generating and registering sales data such as the number of articles contained in the product and the sales price.

  In the present embodiment, the storage unit such as the RAM 3 stores identification information for identifying a container, identification information for identifying an article contained in the container, unit mass data of the article, and a unit price of the article contained in the container. Is stored in association with. The product registration unit 102 (product registration means) is weighed based on the specific information specifying the container determined by the container determination unit 101 (container determination means) when the determined container is a product to be sold by weighing. Product sales data is generated based on the mass data obtained by subtracting the mass data of the container from the mass data of the product and the unit price of the item, and if the determined container is not a product sold by weighing, the measured mass data of the item The number of articles is calculated based on the mass data obtained by subtracting the mass data of the container from the unit and the unit mass data of the article, and the sales data of the article is generated based on the calculated number and the unit price of the article. For this reason, it is possible to generate optimal sales data according to the sales form without performing complicated operations by the operator.

  Further, in the embodiment of the present invention, the control unit 1 determines whether or not the commodity is appropriately placed in the commodity recognition range 61 a by the imaging unit 8 by the imaging data (image data) generated by the imaging unit 8. If it is determined that the product is not properly placed in the recognition range 61a, an error process is performed. For this reason, it is possible for the operator to place a product in the recognition range 61a by the imaging unit 8, and to provide the product sales data processing device 100 capable of specifying the container of the product.

  In the present embodiment, each pixel of the image data (image data) imaged by the imaging unit 8 is binarized, and the container and the background portion other than the container are clearly separated, so that the area and the shape of the container are obtained. Etc. can be easily specified. The area of the container and the type of the container are stored in a storage unit such as the RAM 3 in advance. The control unit 1 can obtain the area of the container placed on the weighing unit 7 by binarizing the imaging data (image data) of the product imaged by the imaging unit 8 and obtain the area of the container. The type of the container stored in the storage unit can be easily specified based on the information.

Also, depending on the installation location of the device (the environment in which the illuminance in the room changes due to external light), it is assumed that the illuminance in the room changes due to the weather, time zones such as morning, daytime, night, and indoor lighting. The values of the luminance, gamma, color, and the like of each pixel of the image data (image data) imaged by the imaging unit 8 greatly change. In the present embodiment, as calibration, a mounting surface (the color of the mounting surface is a single color) is imaged in a state where no container or the like is mounted, and the brightness, gamma, and color of the captured image (imaging) data are taken. Are adjusted (corrected), and the values of the corrected (adjusted) luminance, gamma, color, and the like are set as threshold values for the binarization processing. This makes it possible to reliably identify the container from the image data captured by the imaging unit 8 in a state where the container is mounted on the mounting surface. In addition, a correction value such as lens distortion may be stored in addition to the calibration.
More specifically, for example, the mounting surface is imaged by the imaging unit 8 for each time period, and a threshold value for the binarization process is defined based on the image data, and stored in the storage unit. The control unit 1 performs a binarization process on the image data captured by the imaging unit 8 using the threshold value of the binarization process for each time zone stored in the storage unit, specifies the area of the container, The type of the container can be reliably specified from the area of the container. Note that when storing in the storage unit, a value (threshold value of the binarization process) for each time zone of morning, daytime, and night (a threshold value of the binarization process) and a switching time of the usage time zone in the morning, daytime, and nighttime are stored. And automatically calibrate the value (threshold for the binarization process) for each time zone based on the time measured based on the time measuring means and the switching time. Switching may be performed. Further, an illuminometer or the like may be provided in the apparatus, and a calibrated value (threshold for the binarization process) may be automatically switched based on the value indicated by the illuminometer.
