Description

  The present invention relates to a merchandise sales data processing apparatus for processing merchandise sales data generated by face-to-face sales with a customer and a computer program therefor, and more particularly to a display technique for transaction information.

  In recent years, a wireless tag is attached to a product, data related to the product with the wireless tag attached to the wireless tag memory, for example, a product code, is stored, and product sales data processing and product management are executed using the data. Various technologies have been proposed and put into practical use. In addition, in POS terminals used in various stores such as convenience stores, supermarkets, drug stores, suburban large stores, etc., products stored in the memory of wireless tags attached to products stored in shopping baskets It is expected to enable efficient checkout by reading data such as codes all at once. With regard to collective reading of wireless tags attached to such a plurality of products, earnest research has been carried out, and it is considered that it will become widespread in the future.

  On the other hand, in various stores as described above, when data such as the product code stored in the memory of the wireless tag attached to the product that the customer desires to purchase is read, the read product code Based on this, data such as the name and unit price of the corresponding product is retrieved and displayed as a purchased product on the display. In general, the purchased product is displayed on both a cashier display directed to the store clerk side and a customer display directed to the customer side. The display display in this case is generally a list display (see, for example, FIG. 11 of Patent Document 1).

  Further, focusing on the aspect of displaying useful information on the display of the POS terminal, it has been proposed that the delivery information is displayed on the display when the customer wishes to deliver the purchased product. For example, in Patent Document 2, a membership code is magnetically read from a membership card, which is a magnetic card, and delivery destination data for specifying a delivery destination is acquired from a store server using the read membership code as a search key and displayed on a display. A technique is disclosed (see paragraphs 0031 to 0038, FIG. 8 and the like).

JP 2005-339353 A Japanese Patent Laid-Open No. 2002-269641

  In general, at various stores as described above, a customer brings a product to be purchased to a checkout counter in a state of being stored in a shopping basket prepared by the store. The store clerk who is the cashier looks at the product he / she wishes to purchase brought to the checkout counter for the first time. In this case, it goes without saying that the product desired to be purchased is an actual product. On the other hand, the list of purchased products displayed on the display by reading the product code attached to the actual product is expressed by the symbol of characters. For this reason, when trying to match the products stored in the shopping basket with the products listed on the display, it is necessary to compare and contrast the real world with the symbolized world.

  Here, in the case of a checkout method in which the product code of each product is read and the product information of the product is added to the list display on the display, each time a product is taken out from the shopping basket, the list is displayed on the actual product and display. Since the displayed symbolized product is compared and contrasted, even when a plurality of products are collated, the collation operation is relatively easy. On the other hand, in the checkout method in which the wireless tags attached to a plurality of products are collectively read and the product information of each product is displayed in a list at once, such a collation operation does not easily proceed. Because there is a need to compare multiple real products that are still stored in the shopping basket with multiple symbolized products that are listed on the display, the number of items to be compared at one time increases. is there.

  As described above, the difficulty in collating the individual products brought to the checkout counter with the products displayed on the display has been described. If you use a checkout method that reads the RFID tags attached to multiple products brought to the checkout counter at once and displays the product information of each product on the display at once, such verification work Becomes extremely difficult. Such difficulty becomes more difficult as items to be collated further increase in addition to collation between individual products brought to the checkout counter and products displayed on the display. As an example, it is assumed that the distinction between take-out merchandise and delivery merchandise is added as a matter to be verified.

  Regarding delivery products, the technology for displaying the delivery destination on the display was first introduced (see Patent Document 2). When considering real transactions, it often happens that a customer wants to take home for some items but wants to deliver for some other items. Therefore, in this case, in addition to the matching work between the individual products brought to the checkout counter and the products displayed on the display, there is no matching work as to whether each product is a take-out product or a delivery product. Don't be. However, even if each item listed is displayed as a take-out product or a delivery product, it is a take-out product and which is a take-out product for the actual product brought to the checkout counter. It is difficult to see at a glance whether it is a product. When using a checkout method that reads the RFID tags attached to multiple products brought to the checkout counter at once and displays the product information of each product on the display at the same time, the difficulty is further increased. Rise.

  An object of the present invention is to adopt a checkout method in which wireless tags attached to a plurality of products brought to a checkout counter are collectively read and product information of each product is displayed on a display at a time. However, it is to facilitate the collation operation between the individual products brought to the checkout counter and the products displayed on the display.

  An object of the present invention is to adopt a checkout method in which wireless tags attached to a plurality of products brought to a checkout counter are collectively read and product information of each product is displayed on a display at a time. However, it is easy to check whether each item brought to the checkout counter is a take-out item or a delivery item.

  The merchandise sales data processing apparatus of the present invention is attached to a checkout counter having a merchandise placement area for placing merchandise to be purchased, a display for displaying information, and a merchandise placed in the merchandise placement area. A wireless communication unit that executes data communication with the wireless tag for short-range wireless communication that is performed, acquires the stored data from the wireless tag, and a product code included in the stored data acquired by the wireless communication unit A product sales data process including a settlement process based on the product sales data processing, and a control unit that executes display control of the display during the product sales data processing, the display control of the control unit, on the display, Take-out merchandise recorded in the stored data and delivery of product morphological images acquired from the storage based on the stored data acquired by the wireless communication unit It is displayed in a different representation mode according to another with goods.

  The product sales data processing apparatus of the present invention viewed from another aspect includes a checkout counter having a product placement area for placing a product to be purchased, a display for displaying information, and a product placement area. A wireless communication unit that executes data communication with a wireless tag for short-range wireless communication attached to the placed product, and acquires stored data from the wireless tag, and (1) a product code and the product The product code included in the storage data acquired by the wireless communication unit is accessed by accessing a storage unit that stores a product image database that stores image data of a morphological image that visually represents the form The corresponding image data is acquired, and the morphological image based on the acquired image data is displayed in different representation modes according to different take-out products and delivery products recorded in the stored data. A process of displaying a transaction image expanded in the X-axis direction and the Y-axis direction in the display area of the spray, and (2) settlement based on a product code included in the stored data acquired by the wireless communication unit And processing for executing merchandise sales data processing including processing.

  The computer program for processing product sales data according to the present invention is mounted on a checkout counter having a product placement area for placing a product to be purchased, a display for displaying information, and the product placement area. A wireless communication unit that executes data communication with a wireless tag for short-range wireless communication attached to a product, and acquires a stored data from the wireless tag, is installed in a computer of a product sales data processing device, The wireless communication unit obtains the computer by accessing a storage unit storing a product image database that stores (1) a product code and image data of a morphological image that visually expresses the form of the product in association with each other. The image data corresponding to the product code included in the stored data is acquired, and the morphological image based on the acquired image data is acquired.

  According to the present invention, on the display, the product form image acquired from the storage unit based on the storage data acquired by the wireless communication unit when the product is placed in the product placement area is brought home and the delivery product. Because it is displayed in different expression modes depending on the checkout counter, the wireless tag attached to multiple products brought to the checkout counter is read at once, and the product information of each product is displayed on the display at once Even if the method is adopted, the individual products brought to the checkout counter are compared with the products displayed on the display, and whether the individual products brought to the checkout counter are take-out products. It is possible to intuitively check whether the product is a delivery product, and therefore, the matching work can be facilitated.

(One embodiment of the present invention)
An embodiment of the present invention will be described with reference to the drawings.

  The merchandise sales data processing apparatus according to the present embodiment is an application example to the POS terminal 101 (see FIG. 1 and the like). Before describing the POS terminal 101 in detail, a sales form at a store 301 (see FIG. 1 and the like) where the POS terminal 101 is installed will be described.

  FIG. 1 is a schematic diagram showing a store 301 in which the POS terminal 101 is installed. The store 301 is divided into a sales floor 302, a checkout corner 303, and a backyard 304. When the entrance door 305 of the store 301 is opened, it reaches the sales floor 302 and enters the checkout corner 303 from the sales floor 302 through the passage 306. The sales floor 302 and the checkout corner 303 and the backyard 304 are partitioned and can be opened and closed by a door 307.

  In the sales floor 302, a plurality of product display shelves 308 are arranged, and in addition to the actual products A, order tags O are displayed on these product display shelves 308.

  In the checkout corner 303, two POS terminals 101 are installed.

  A store server 401 is installed in the backyard 304.

  Here, the actual product A and the order tag O will be described. The actual product A is a product that can be taken home after purchase, and the order tag O represents a product that is delivered after purchase as a tag. That is, the product placed in the product placement area 105 (see FIG. 2) described later indicates the actual product A and the order tag O. A radio tag (not shown) for near field communication is attached to both the actual product A and the order tag O. In the wireless tag memory, various types of product information about the product A to which the wireless tag is attached or the product represented by the order tag O is stored and stored. Typical product information is a product code for identifying the type of the product. In addition, an identification code for identifying the actual product A and the order tag O is also stored and stored in the memory of the wireless tag. An identification code that identifies an actual product in the wireless tag memory attached to the actual product A, and an identification code that identifies an order tag in the wireless tag memory attached to the order tag O Is stored and saved. As an example, the order tag O has a card form or a stick form. As long as it can be displayed on the merchandise display shelf 308, the order tag O may have any form. However, on the order tag O, it is desirable that the name, price, etc. of the product represented by it be displayed by printing or the like.

  FIG. 2 is a perspective view showing the POS terminal 101 that is being sold face-to-face. The POS terminal 101 includes a checkout counter 102 as a component, and is configured integrally with the checkout counter 102. The checkout counter 102 includes a display 103 that displays information in a partial area of the top plate surface. As the display 103, a liquid crystal display, a plasma display, or the like can be used. A touch panel 104 is stacked on such a display 103. On the top surface of the checkout counter 102, another partial area where the display 103 and the touch panel 104 are not arranged is a product placement area 105 for placing a product to be purchased. The distinction between the arrangement area of the display 103 and the touch panel 104 and the product placement area 105 on the top surface of the checkout counter 102 is as shown in FIG. In FIG. 4, for convenience, the arrangement area of the display 103 and the touch panel 104 is indicated as OA, and the product placement area 105 is indicated as PA.

  The checkout counter 102 includes a short-distance wireless communication unit 106, a short-distance wireless communication reader / writer 107, and a scale unit 108 (see FIG. 3).

  The wireless communication unit 106 performs data communication with a wireless tag for short-range wireless communication attached to an item placed in the product placement area 105, and acquires stored data from the wireless tag. That is, the wireless communication unit 106 embeds an antenna (not shown) in the product placement area 105 and performs data communication with the wireless tag using RFID (Radio Frequency Identification) technology. An object with which the wireless communication unit 106 performs short-distance wireless communication is typically a wireless tag attached to the above-described actual product A and order tag O. In addition, the wireless communication unit 106 also performs short-range wireless communication with the wireless tag built in the member card C possessed by the customer. In this case, the member card C is in a state of being attached to the shopping basket 309 for storing the product A and the order tag O placed in the product placement area 105.

  The reader / writer 107 communicates with a non-contact type IC chip that can be settled by RFID technology. As an example, an IC chip having a data structure for storing and saving electronic money having a value equivalent to cash is used. As another embodiment, the IC chip may be of a debit type that stores and saves an identification number for specifying a debited bank account and is used for settlement. In any case, the IC chip is embedded in, for example, a card or built in a mobile phone.

  The scale unit 108 is configured by a load cell scale as an example, and weighs the weight of an item placed on the product placement area 105 arranged on the top plate surface of the checkout counter 102.

  As shown in FIG. 2, the POS terminal 101 according to the present embodiment is configured to sell products in a state where a clerk who is a cashier and a customer face each other across a checkout counter 102. At this time, the POS terminal 101 displays on the display 103 a transaction screen 151 including transaction information such as a product to be purchased by the customer, its unit price, and the total amount. As described above, the display 103 is arranged upward on the top plate surface of the checkout counter 102. Therefore, the POS terminal 101 displays the transaction information at a unique position on the top surface of the checkout counter 102 that can be viewed by both the clerk and the customer. Both the store clerk and the customer can change the display state displayed on the display 103 or input a specific instruction by touching the touch panel 104 as necessary. This point will be described later in detail with reference to FIGS.

  The POS terminal 101 first displays a background image 152 that is the basis of the transaction screen 151 on the display 103. When the shopping basket 309 storing the product A and the order tag O is placed in the product placement area 105 of the checkout counter 102, the product A and the order tag O acquired by the wireless communication unit 106 are stored. A product form image 153 acquired from a product image database 210c (see FIG. 3), which will be described later, based on stored data of an attached wireless tag (not shown) is developed and displayed on the background image 152. At this time, the products developed and displayed on the background image 152 are all products whose stored data is read from the wireless tag as long as they can be displayed as one screen.

  FIG. 3 is a block diagram illustrating a hardware configuration of the POS terminal 101. As described above, the POS terminal 101 executes information display processing on the display 103 and information input processing from the touch panel 104, and performs wireless communication with the wireless tag and short-range wireless communication. A data reception process from the reader / writer 107 and the scale unit 108 that executes a data transmission / reception process with the IC chip of the mold is executed, and further a merchandise sales data process including a settlement process is executed. Such various processes are performed by the control unit 201. For example, the control unit 201 may have a semiconductor chip configuration in which an operation sequence is written or a microcomputer configuration that operates by storing a program in a memory. Here, the control unit 201 having a microcomputer configuration is introduced.

  The CPU 202 is the core of the control unit 201. The CPU 202 is connected via a system bus 207 to a ROM 203 that stores fixed data fixedly, a RAM 204 that stores variable data in a rewritable manner, a VRAM 205 that generates a display image to be displayed on the display 103, and an HDD 206. ing. The HDD 206 stores an OS 208 (operating system), a merchandise sales data processing computer program 209, a merchandise data file 210, and an image library 211. The OS 208, the computer program 209, the product data file 210, and the image library 211 are all or partially transferred to the RAM 204 and used when the POS terminal 101 is activated.

  The product data file 210 is a file for storing information on various products handled in the store 301, and includes a PLU file 210a, a product weight database 210b, and a product image database 210c.

  The PLU file 210a stores the unit price of the product in association with the product code specifying each product.

  The product weight database 210b stores the weight of the product in association with the product code specifying each product. The weight is stored as a single weight value as an example, and is stored as an upper limit value and / or a lower limit value that should be allowed for a single weight value as another example. The value range is stored.

  The product image database 210c stores image data of products in association with product codes specifying individual products. The image data is image data of a form image that visually represents the form of the product. As such image data, for example, a two-dimensional illustration, a three-dimensional illustration, or a photograph taken by a digital camera that realistically or impressively represents the appearance of a product is used.

  The image library 211 is composed of various image data and frame images necessary for executing the computer program 209. Therefore, the product image database 210c constitutes a part of the image library 211.

  The control unit 201 includes a display 103, a touch panel 104, a wireless communication unit 106, a reader / writer 107, and a scale unit 108 via controllers and interfaces (all not shown) of those devices connected to the system bus 207. It is connected. Accordingly, the display 103, the touch panel 104, the wireless communication unit 106, the reader / writer 107, and the scale unit 108 are controlled by the control unit 201.

  A communication interface 212 is also connected to the control unit 201 via the system bus 207. The communication interface 212 is connected to the local communication network 402, for example, and realizes data communication between various external devices such as the store server 401 installed outside and the control unit 201.

  FIG. 4 is a plan view of the POS terminal 101 showing a state in which a sales standby screen is displayed on the display 103. As described above, in FIG. 4, for convenience, the arrangement area of the display 103 and the touch panel 104 is indicated as OA, and the product placement area 105 is indicated as PA. In the product placement area 105 written as PA, an instruction for the customer “please put a basket here” is printed and printed.

  The control unit 201 controls the display 103 to display the background image 152 in the arrangement area OA of the display 103 and the touch panel 104. The background image 152 is generated based on image data included in the image library 211 installed in the HDD 206 and copied to the RAM 204. The image data that is the basis of the background image 152 is a two-dimensional illustration or a three-dimensional illustration.

  The control unit 201 also controls the display 103 to display a transaction information display field 154 in the arrangement area OA of the display 103 and the touch panel 104. In the transaction information display column 154, a transaction information display column 154a for the store clerk directed to the store clerk who is the cashier and a transaction information display column 154b for the customer directed to the customer side are prepared. The transaction information display field 154a for the store clerk includes a total amount field 154a-1, a discount amount field 154a-2, and a purchase points field 154a-3. Further, a reverse display instruction button 154a-4 and a list display are displayed. An instruction button 154a-5 is included. The customer transaction information display field 154b includes a payment amount field 154b-1, a discount amount field 154b-2, a delivery date / time designation field 154b-3, and a point designation field 154b-4. A list display instruction button 154b-5 and a holding position display 154b-6 are included.

  The total amount column 154a-1 and the payment amount column 154b-1 are columns for displaying the total amount of products that the customer intends to purchase.

  The discount amount column 154a-2 and the discount amount column 154b-2 are columns for displaying the discount amount.

  The purchase points column 154a-3 is a column for displaying the purchase points displayed only in the transaction information display column 154 for the store clerk.

  The reverse display instruction button 154a-4 is an object for instructing the reverse of the display content of the background image 152 displayed only in the transaction information display field 154a for the store clerk. Here, the inversion means that the display direction of the display content of the background image 152 is switched between the store clerk side and the customer side.

  The list display instruction button 154 a-5 and the list display instruction button 154 b-5 instruct to display a list of products displayed on the background image 152 as product form images acquired from the product image database 210 c (see FIG. 3). It is an object for.

  The delivery date / time designation field 154 b-3 is an object that is displayed only in the customer transaction information display field 154 b and is used to change and designate the delivery date / time displayed as a default by a touch operation on the touch panel 104. In this case, the delivery date and time displayed by default is set based on information stored in the data stored in the wireless tag built in the member card C possessed by the customer and attached to the shopping basket 309. As an example, assuming that “9:00 am to 11:00 am the next day of the settlement date” is stored as the data stored in the wireless tag, the delivery date / time designation field 154 b-3 has “Tomorrow 9: 00 to 11”. : 0 "is displayed as a default.

  The point designation column 154b-4 is an object that is displayed only in the customer transaction information display column 154b, and displays the current accumulated point number of the customer and the number of points used. The number of accumulated points is set based on information stored in the storage data of the wireless tag built in the member card C that is held by the customer and attached to the shopping basket 309. The default setting for the number of use points is “0” and can be changed by a touch operation on the touch panel 104.

  The holding position display 154b-6 is displayed only in the customer transaction information display field 154b, and indicates the holding position of a medium containing a non-contact type IC chip that can be settled. As described above, such a medium is built in a card, a mobile phone, or the like. As described above, the position display 154b-6 indicates the position where the non-contact IC chip that can be settled built in the card or the mobile phone is held, and therefore the reader / writer 107 (see FIG. 3). An antenna (not shown) is positioned below the holding position display 154b-6.

  FIG. 5 is a plan view of the POS terminal 101 showing the moment when the shopping basket 309 in which the product A or the like is stored in the product placement area 105 is placed. The customer takes the actual product A to be purchased from the product display shelf 308 installed in the store 301 or the order tag O corresponding to the product and stores it in the shopping basket 309. At this time, as an example, for the actual product A, the my bag 310 brought by the customer is stored in the shopping basket 309 and stored in the my bag 310. On the other hand, the order tag O is stored in a storage area other than the my bag 310 of the shopping basket 309. By doing this, the customer can quickly leave with the my bag 310 after collecting the membership card C from the shopping basket 309 after the settlement is completed. Further, the store side can quickly send the order tag O remaining in the shopping basket 309 for delivery. In this way, a smooth checkout is realized.

  FIG. 6 is a flowchart showing the overall processing flow. The processing shown in this flowchart is executed by the CPU 202 in accordance with a computer program 209 that is installed in the HDD 206 and is entirely or partially copied to the RAM 204.

  As shown in FIG. 5, when the shopping basket 309 is placed in the product placement area 105, the wireless communication unit 106 is attached to the product A, the order tag O, and the shopping basket 309 stored in the shopping basket 309. Short-distance wireless communication is performed with the member card C, and the stored data is acquired from the product A, the order tag O, and the wireless tag attached to the member card C. The wireless communication unit 106 transmits the acquired storage data of the wireless tag to the control unit 201 via the system bus 207. Thereby, the CPU 202 determines reception of the wireless tag data (Y in step S101).

  When the CPU 202 determines reception of the wireless tag data (Y in step S101), the CPU 202 searches the data buffer in the RAM 204 (step S102), and determines the presence or absence of the same wireless tag data (step S103). If the same wireless tag data is stored in the data buffer as a result of this determination (Y in step S103), the wireless tag data determined to be received in step S101 is discarded and the process returns to the determination process in step S101 ( Step S104). On the other hand, if the same wireless tag data is not stored in the data buffer as a result of the determination in step S103 (N in step S103), the wireless tag data received and determined in step S101 is stored in the data buffer. (Step S105). At this time, the wireless tag data stored in the data buffer is the data of the wireless tag attached to the product A or the order tag O, the data of the wireless tag built in the member card C, or other wireless tags. It is data.

  In step S106, the CPU 202 determines whether the wireless tag data stored in the data buffer in step S105 is data of the wireless tag attached to the product A or the order tag O. If the result of this determination is negative (N in step S106), the process returns to step S101. On the other hand, when the result of the determination is affirmative (Y in step S106), a search process of searching the product data file 210 and acquiring corresponding product information is executed (step S107). That is, the CPU 202 searches the product data file 210 using the product code included in the data stored in the wireless tag attached to the product A or the order tag O as a search key, acquires the unit price from the PLU file 210a, The weight is acquired from the weight database 210b, and the image data is acquired from the product image database 210c.

  In addition to such search processing, various embodiments can be implemented. For example, all or part of the product data file 210 is stored and stored in the store server 401 or stored in an external storage device (not shown) accessible by the store server 401, and the POS terminal 101 is connected to the local communication network. Necessary data may be acquired from the store server 401 via 402. As still another embodiment, all or part of the unit price, weight, and image data is stored in the wireless tag itself, and the POS terminal 101 acquires necessary data from the wireless tag itself. Also good. After all, these various variations are where the unit price, weight, and image data of the product specified by the product A or the order tag O with the wireless tag to be read by the wireless communication unit 106 are stored. Depends on.

  In step S108, the CPU 202 displays the product form image 153 based on the image data included in the product information acquired in step S107 on the background image 152 displayed on the display 103. That is, the control unit 201 develops and displays the product form image 153 acquired from, for example, the product image database 210c on the background image 152 based on the storage data acquired by the wireless communication unit 106 by the display control. Thereby, the transaction screen 151 is displayed. Thus, the transaction screen 151 displayed in accordance with step S108 is displayed facing the store clerk who is the cashier. First, the store clerk needs to check the identity of the product specified by the actual product A and the order tag O stored in the shopping basket 309 and the product developed on the display 103 as the transaction screen 151. is there.

  FIG. 7 is a schematic diagram showing a state in which product information read from the product A or the like stored in the shopping basket 309 is displayed on the display 103 toward the store clerk side. As illustrated in FIG. 7, the product form image 153 based on the image data included in the product information acquired in step S <b> 107 is displayed on the background image 152 displayed on the display 103. The product form image 153 illustrated in FIG. 7 is expressed by adding the name and unit price of the product to the three-dimensional illustration of the corresponding product. As an example, the illustration, name, and unit price included in the form image 153 are prepared in advance as image data stored in the product image database 210c. As another example, only the image data of illustration is stored in the product image database 210c, and the name and unit price of the corresponding product are stored in, for example, the PLU file 210a, and the form image 153 is combined by combining these illustrations with the name and unit price. You may make it produce | generate. In this case, only the text data of the name and unit price may be stored in the PLU file 210a, and the text data may be converted into image data and displayed each time the form image 153 is displayed.

  As shown in FIG. 7, the background image 152 has a take-out product display area 152a in the central portion, and a delivery product display area 152b in an area that is closer to one side. One group of the morphological images 153 (morphological image 153a) is displayed as a take-out product in the appearance form itself of the product developed two-dimensionally or three-dimensionally in the take-out product display area 152a. Another group (image 153b) of the morphological images 153 is displayed as a delivery product in a tiled form in the delivery product display area 152b. In this case, the tile form is displayed in a form in which an image representing the appearance of the product is expanded two-dimensionally or three-dimensionally in the tile. The form image 153a displayed in the take-out product display area 152a is an image displayed based on the product information read from the wireless tag attached to the actual product A. The form image 153b displayed in the delivery product display area 152b is an image displayed based on product information read from the wireless tag attached to the order tag O. For such distinction, the wireless tag attached to the actual product A and the wireless tag attached to the order tag O include an identification code that can distinguish between the actual product A and the order tag O. Can be easily realized. That is, when the CPU 202 receives an identification code indicating that the wireless tag is attached to the actual product A, the CPU 202 acquires a display frame capable of displaying the morphological image 153a from the image library 211, The image data of the product acquired from the product image database 210c is displayed in combination with this display frame. Further, when the CPU 202 receives the identification code indicating that the wireless tag is attached to the order tag O, the CPU 202 acquires a display frame capable of displaying the morphological image 153b from the image library 211. The image data of the product acquired from the product image database 210c is displayed in combination with the display frame.

  Thus, according to the present embodiment, the product image database 210c (see FIG. 3) based on the storage data acquired by the wireless communication unit 106 in the background image 152 displayed on the display 103 by the display control of the control unit 201. The form image 153 of the product acquired from is developed in different expression modes according to the take-out product and the delivery product recorded in the stored data. In this case, different expression modes are realized by making the shape image 153 different in take-out merchandise and delivery merchandise. That is, the form image 153a shown in the appearance form itself of the product developed two-dimensionally or three-dimensionally expressing that it is a take-out product and the tile expressing that it is a delivery product. A take-out product and a delivery product are distinguished from each other by a form image 153b in which an image representing the appearance of the product is displayed in a two-dimensional or three-dimensionally developed form. Different expression forms are also realized by making the display area of the form image different between the take-out product and the delivery product. That is, the take-out product is displayed in the take-out product display area 152a, and the delivery product is displayed in the delivery product display area 152b, thereby distinguishing between the take-out product and the delivery product.

  Returning to the description of the flowchart shown in FIG. After displaying and displaying the transaction screen 151 on the display 103 (see step S108), the CPU 202 calculates the total price and the total score of the sales items (step S109). The total amount is calculated based on the unit price acquired from the PLU file 210a included in the product data file 210. The calculation of the total score is executed based on the number of times that the wireless tag is attached to the product A or the order tag O in step S106.

  And CPU202 displays the transaction information etc. which were obtained by the process of step S109 on the transaction information display column 154 currently displayed on the display 103 (step S110). That is, in the transaction information display field 154a for the salesclerk who is the cashier, the total price calculated in step S109 is displayed in the total price field 154a-1, and the discount price field 154a-2 is displayed in the step. The total discount amount for each product acquired from the PLU file 210a in S107 is displayed, and the total score calculated in step S109 is displayed in the purchase score field 154a-3. Further, in the customer transaction information display field 154b directed to the customer side, the total amount calculated in step S109 is displayed in the payment amount field 154b-1, and the PLU file in step S107 is displayed in the discount amount field 154b-2. The sum of the discount amount for each product acquired from 210a is displayed. The delivery date / time designation field 154b-3 displays a default value for the delivery date / time acquired from the wireless tag incorporated in the member card C stored in the buffer of the RAM 204 in step S105. Further, the point designation field 154b-4 displays the number of points acquired from the wireless tag built in the member card C stored in the buffer of the RAM 204 in step S105.

  Thereafter, the CPU 202 executes a weight check process (steps S111 to S113). In the weight check process, first, the sum of the weight values acquired by the search process in step S107 is calculated as a total weight value (step S111). Then, a measurement value measured by the scale unit 108 and output from the scale unit 108 is acquired (step S112). Then, the total weight value calculated in step S111 is compared with the measured value from the weighing unit 108 acquired in step S112, and the identity is determined (step S113).

  Here, as an example, whether the total weight value calculated in step S111 and the measured value from the scale unit 108 acquired in step S112 have the same value is the lower limit value of the weight acquired by the search process. This is done by determining whether it is within the upper limit. In this case, the weight check in the present embodiment is not a weight check for each individual product, but all products A and order tags O stored in the shopping basket 309 placed in the product placement area 105. It is a weight check for the total value of its own weight. Therefore, when determining the identity between the measurement value and the weight value, the total value of the lower limit values of all products and the total value of the upper limit values of all products, which are weight values obtained by the search process, constitutes an allowable range. Then, it is determined whether or not the measurement value is within the allowable range. However, the allowable range acquired by such a technique is merely an example in implementation, for example, the width of the allowable range is narrowed by multiplying a coefficient in the value of the allowable range, You may make it wide on the contrary. As another example, the lower limit value and the upper limit value are not acquired by the search process, or even if they are acquired, those values are not used, only the weight value obtained by the search process is used and added. The total value may be calculated, and a certain allowable range may be set for the total value to obtain the total weight value.

  If the CPU 202 does not determine the identity between the calculated total weight value and the measurement value acquired from the scale unit 108 in step S113 (N in step S113), the CPU 202 returns to the process in step S101, and again, Steps S101 to S113 are executed. This is because the product A or the like for which product information has not been acquired in step S107 should remain in the shopping basket 309.

  When the CPU 202 determines the identity between the calculated total weight value and the measured value acquired from the scale unit 108 in step S113 (Y in step S113), the transaction screen 151 displayed on the display 103 is displayed. Is switched to the customer side (step S114).

  FIG. 8 is a plan view of the POS terminal 101 showing a state in which the product information shown in FIG. 7 is reversed and displayed toward the customer side. As is apparent from comparison with the display state shown in FIG. 7, in the display state shown in FIG. 8, the display orientation of the transaction screen 151 displayed on the display 103 is switched. As a result, on the customer side, the product developed on the display 103 as the transaction screen 151 can be easily confirmed. Moreover, the display position of the transaction screen 151 displayed on the display 103 is a position that does not change before and after the display direction is reversed. Thereby, the product developed on the display 103 as the transaction screen 151 can be further easily confirmed.

  Returning to the description of the flowchart shown in FIG. After displaying the transaction screen 151 for the customer (step S114), the CPU 202 displays a dialog prompting payment on the display 103 (step S115). And it waits for the completion determination of payment (step S116).

  A customer who sees a dialog for prompting settlement is prompted to perform a settlement operation. For example, the customer performs settlement using a medium that has a contactless IC chip that can be settled, such as a mobile phone. In this case, a mobile phone or the like is held over the position position display 154b-6 located on the rightmost side of the transaction information display field 154b directed to the customer. As a result, payment by electronic money stored in a non-contact type IC chip built into a mobile phone becomes possible as an example, and as another example, a non-contact type IC chip built into a mobile phone stores data. Debit payment based on the information is available.

  When the CPU 202 determines completion of payment (Y in step S116), the CPU 202 transmits the detailed data to the store server 401 and the mobile phone used by the customer for payment (step S117). Transmission of detailed data to the store server 401 is executed by wired data transfer performed from the communication interface 212 via the local area communication network 402. Transmission of detailed data to a mobile phone or the like possessed by the customer is executed by short-range wireless communication by the reader / writer 107.

  Thereafter, the CPU 202 deletes the information displayed in the transaction information display field 154 (step S118), clears the buffer in the RAM 204 (step S119), and ends the processing of one transaction.

  As described above, according to the present embodiment, the background image 152 is displayed on the display 103. Then, when the product A or the like is placed in the product placement area 105, the form image 153 of the product is developed and displayed on the background image 152 in different expression modes depending on the take-out product and the delivery product. Therefore, the checkout method is adopted in which the wireless tags attached to the plurality of products A brought to the checkout counter 102 are collectively read and the product information of each product is displayed on the display 103 at a time. However, it is possible to intuitively compare the individual products brought to the checkout counter with the products displayed on the display 103, and the individual products brought to the checkout counter are brought home. It is possible to intuitively check whether the item is a product or a delivery product, and therefore, the matching operation can be facilitated.

  Further, according to the present embodiment, the display 103 is arranged upward on the top plate surface of the checkout counter 102. As a result, the checkout process can be performed while the store clerk who is the cashier and the customer confirm the same screen. Even in this case, two transaction information display fields 154 (transaction information display field 154a and transaction information display field 154b) respectively directed to the store clerk side and the customer side are provided. This makes it easy to confirm transaction information. In addition, since the display direction of the transaction screen 151 is reversed and displayed on the clerk side and the customer side, it is easy for both the clerk and the customer to confirm the purchased product. In this case, the display direction of the transaction screen 151 is initially set to the clerk side, and when the weight check process is passed (Y in step S113 in FIG. 6) is set to the customer side, In contrast, information on purchased products can be provided in a timely manner.

  However, in the POS terminal 101 according to the present embodiment, the display direction of the transaction screen 151 can be displayed in reverse or according to an object operation on the touch panel 104, or a list of purchased products can be displayed. Both the store clerk and the customer can change the display state displayed on the display 103 or input a specific instruction by touching the touch panel 104 as necessary. Hereinafter, such contents will be described with reference to FIGS.

  FIG. 9 is a flowchart showing a flow of processing for object operation. The CPU 202 is on standby for determining whether there is a screen touch by the touch panel 104 (step S201). Therefore, when it is determined that there is a screen touch (Y in step S201), the type of object is determined (step S202). That is, the CPU 202 determines whether the object touched on the screen is the background (background image 152), the product (morphological image 153), the date / time (delivery date / time designation field 154b-3), or the point (point designation field 154b). -4) or an instruction (reverse display instruction button 154a-4, list display instruction button 154a-5, list display instruction button 154b-5).

  Thereafter, the CPU 202 determines whether or not the screen touch position has moved on the touch panel 104 (step S203). That is, if there is a screen touch on the touch panel 104 and the touch position is moved after that, an object operation other than the instruction is performed. Therefore, in this embodiment, it is determined whether the object operation is an instruction or other than an instruction by determining whether or not the screen touch position has moved on the touch panel 104 (step S203).

If the CPU 202 determines that the screen touch position has been moved on the touch panel 104 (Y in step S203), the CPU 202 recognizes the movement of the touch position and executes an analysis of the object motion according to the recognized movement of the touch position. (Step S204). As an example, the computer program 209 installed in the HDD 206 includes:
(A) Touch position movement from the clerk side to the customer side on the background image 152 (A) Touch position movement from the customer side to the clerk side on the background image 152 (C) Touch of the form image 153a located in the take-out product display area 152a Move the position to the delivery product display area 152b (d) Move the touch position of the form image 153b located in the delivery product display area 152b to the take-out product display area 152a To move the touch position clockwise (f) Move the touch position counterclockwise at the “date” designation position in the delivery date / time designation field 154b-3 (g) at the “time” designation position in the delivery date / time designation field 154b-3 Move the touch position clockwise (K) Move the touch position counterclockwise at the “time” designation position in the delivery date / time designation field 154b-3 (K) In the point designation field 154b-4 Tsu move switch position clockwise (co) Object operation of moving the touch position counterclockwise point designation column 154b-4 are defined. Therefore, the CPU 202 analyzes which of the object motions (A) to (C) has been performed as the object motion corresponding to the movement of the touch position as the process of step S204.

Next, the CPU 202 changes the object display according to the analysis result of the object motion analyzed in step S204 (step S205). As an example, the computer program 209 installed in the HDD 206 includes:
(A) Object operation: Display the transaction screen 151 displayed on the display 103 facing the customer side (A) Object operation: Display the transaction screen 151 displayed on the display 103 facing the store clerk side (C) Object action: The touch-designated morphological image 153a is moved to the delivery product display area 152b to form the morphological image 153b. Move to form image 153a (O) Object action: Advance display of “day” in delivery date / time designation field 154b-3 in the future (F) Object action: “Day” in delivery date / time designation field 154b-3 "" To return to the past (ki) object action: display "time" in the delivery date / time designation field 154b-3 in the future Object action to be performed (K): Return the display of “time” in the delivery date / time designation field 154b-3 to the past (K) Object action: Increase the numerical value displayed as the point (K) Object action: An object display change operation is defined to lower the numerical value displayed as a point. Therefore, the CPU 202 executes the processes according to the above (a) to (co) so that the object display changing operation according to the movement of the touch position is performed as the process of step S205.

Then, the CPU 202 executes an internal process corresponding to the analysis result of the object motion analyzed in step S204 (step S206), and ends the process. As an example, the computer program 209 installed in the HDD 206 includes:
(C) Object action: Change the take-out product specified by the touch-designated form image 153a to a delivery product (d) Object action: Delivery product specified by the touch-designated form image 153b Change the product to a take-out product (e) Object action: Advance the delivery date “day” in the future (f) Object action: Return the delivery date “day” to the past (ki) Object action: (K) object action to advance the delivery date and time in the future: Return the delivery time and time to the past (K) Object action: Increase the number of points discounted from the total sales amount Object behavior: A change in internal processing is defined that lowers the number of points discounted from the total sales amount. Therefore, the CPU 202 executes the processes according to the above (c) to (c) so that the internal process is changed according to the movement of the touch position as the process of step S206.

  FIG. 10 is a plan view of the POS terminal 101 for explaining the reverse display of the display content by manual operation. The transaction screen 151 displayed on the display 103 shown in FIG. 10A is directed to the store clerk side. The transaction screen 151 displayed on the display 103 shown in FIG. 10B is directed to the customer side. Therefore, when the object operation (a) is performed while the transaction screen 151 is displayed on the display 103 in the direction of FIG. 10 (a), the display direction of the transaction screen 151 is as shown in FIG. 10 (b). Invert. On the other hand, when the above-mentioned object operation (a) is performed in a state where the transaction screen 151 is displayed on the display 103 in the direction of FIG. 10B, the display direction of the transaction screen 151 is as shown in FIG. Invert like.

  Returning to the description of the flowchart shown in FIG. If the CPU 202 determines that the screen touch position has not moved on the touch panel 104 (N in step S203), the CPU 202 checks whether the object type determined in step S202 is an instruction (step S207). If the CPU 202 confirms that the instruction is not an instruction (N in step S207), it means that some mistouch has been made on the touch panel 104, and the process returns to the process in step S201. On the other hand, if the CPU 202 confirms that the instruction is an instruction (Y in step S207), the CPU 202 executes the type of instruction determined in step S202 (step S208), and ends the process.

  FIG. 11 is a schematic diagram showing a state in which product information is displayed as a list. Whether the object type is determined to be an instruction in step S202 in the flowchart of FIG. 9 is a case where the reverse display instruction button 154a-4 in the transaction information display field 154a displayed on the store clerk side is touch-designated. Either the list display instruction button 154a-5 is touch-designated or the list display instruction button 154b-5 in the transaction information display field 154b displayed on the customer side is touch-designated. .

  When the reverse display instruction button 154a-4 in the transaction information display field 154a displayed on the store clerk side is touch-designated, the CPU 202 displays a display as shown in FIGS. 10 (a) and 10 (b). The display direction of the transaction screen 151 displayed in 103 is reversed.

  The CPU 202 also specifies that the list display instruction button 154a-5 in the transaction information display field 154a displayed on the store clerk side is touch-designated, or displays the list display instruction button in the transaction information display field 154b displayed on the customer side. When 154b-5 is touch-designated, a list display screen 155 as shown in FIG. The list display screen 155 displays the product name 155a, the number 155b, the discount amount 155c, and the unit price 155d for each product, and further displays the total of the number 155b, the discount amount 155c, and the unit price 155d.

  A unique point on the list display screen 155 is that a reduced form image 153c is displayed as a product name 155a in addition to text display. The reduced form image 153c is generated based on the image data acquired from the product image database 210c.

(Another embodiment of the present invention)
Another embodiment of the present invention will be described with reference to FIG. The same parts as those of the embodiment described with reference to FIGS. 1 to 11 are denoted by the same reference numerals, and the description thereof is also omitted.

  FIG. 12 is a plan view of the POS terminal 101 showing a state in which product information read from the product A stored in the shopping basket 309 is displayed on the display 103. In the present embodiment, the transaction information display field 154b directed to the customer side is not arranged along the side edge of the display 103, and a part of the area where the transaction screen 151 was displayed in the above embodiment. It is arranged. That is, as shown in FIG. 10, when viewed from the customer side, a display area of the transaction information display field 154 b directed to the customer side is secured in the right area of the display 103.

  Further, a unique point in the present embodiment is the display form of the transaction screen 151. In the embodiment, the background image 152 is divided into the take-out product display area 152a and the delivery product display area 152b, whereas in the present embodiment, the background image 152 has no such distinction. In other words, in the embodiment, based on the storage data read from the form tag 153a displayed based on the storage data read from the wireless tag attached to the actual product A and the wireless tag attached to the order tag O. The distinction from the morphological image 153b is made not only by the display mode of the morphological image 153 itself but also by its display area. On the other hand, in this embodiment, such two types of morphological images 153a and 153b are distinguished only by the display mode of the morphological image 153 itself. These two types of morphological images 153a and 153b are displayed in a random display orientation on a single background image 152 whose regions are not distinguished, and constitute a transaction screen 151. Therefore, it is not necessary to switch the display direction of the transaction screen 151 between the store clerk side and the customer side, and the individual form images 153a and 153b can be easily recognized at a glance from either side. Therefore, the reverse display instruction button 154a-4 provided in the transaction information display field 154 of the above embodiment is not provided.

(Another embodiment of the present invention)
