DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, the embodiments will be described in detail with reference to the drawings. In the embodiments, a self-service POS terminal will be described as an example of a sales data processing device. However, the present invention is not limited to the embodiments described below.

[0009] Fig. 1 is a front view showing an example of the appearance of a self-service POS terminal 1 according to an embodiment. As shown in Fig. 1, the self-service POS terminal 1 has, for example, a vertically elongated, approximately rectangular parallelepiped shape and includes a first housing 2 and a second housing 3. The first housing 2 is located on the lower side of the approximately rectangular parallelepiped shape and houses a deposit / withdrawal unit 4 therein. Under the control of a control unit 100, which will be described later, the deposit / withdrawal unit 4 deposits money received from a customer and dispenses change to be paid to the customer.

[0010] The second housing 3 is located on the upper side of the approximately rectangular parallelepiped shape and houses the control unit 100, which will be described later. The second housing 3 also includes a code reading unit 5, a card reading unit 6, and a printing unit 7 as interfaces operated by the user.

[0011] The code reading unit 5 is a reading device that reads information stored in a code symbol such as a barcode or a two-dimensional code. The code reading unit 5 reads the code symbol through a reading window 51 formed in the second housing 3. For example, the code reading unit 5 reads a code symbol attached to a product or a code symbol displayed on a user's mobile terminal, etc.

[0012] The card reading unit 6 is a reading device that reads information stored on a card-type medium. The card reading unit 6 reads information from a card medium inserted into the card insertion slot 61. For example, the card reading unit 6 reads information related to electronic payment from a credit card or an electronic money card.

[0013] The printing unit 7 is a printing device such as a thermal printer. The printing unit 7 prints receipts for the products purchased by the user and outputs (issues) the printed receipts from a receipt issuing port 71 formed in the second housing 3.

[0014] The self-service POS terminal 1 also includes a display operation unit 8. The display operation unit 8 is provided on the top surface of the second housing 3 or the like. The display operation unit 8 has a display unit 81 configured with a display device such as an LCD (Liquid Crystal Display), and an operation unit 82 configured with a touch panel or the like. The display unit 81 displays various information and images under the control of the control unit 100, which will be described later. The operation unit 82 is provided on the surface of the display unit 81, and outputs information to the control unit 100 based on the position touched by the user.

[0015] A basket stand 9 is provided on one side or beside the self-service POS terminal 1. The basket stand 9 is a stand for placing a basket, and is used, for example, when placing a basket containing products thereon.

[0016] The configuration of the self-service POS terminal 1 is not limited to that shown in Fig. 1. For example, the self-service POS terminal 1 may include a bagging table or the like for bagging the products after the code symbols have been read by the code reading unit 5. In this case, it is preferable that the bagging table be provided, for example, on the other side of the self-service POS terminal 1 (opposite the basket placement table 9).

[0017] Fig. 2 is a diagram showing an example of the hardware configuration of the self-service POS terminal 1. As shown in Fig. 2, the self-service POS terminal 1 includes the above-mentioned deposit / withdrawal unit 4, code reading unit 5, card reading unit 6, printing unit 7, display unit 81, operation unit 82, etc.

[0018] The self-service POS terminal 1 also includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a storage unit 14, an audio output unit 15, and a communication unit 16. The CPU 11 is connected to each of the hardware components shown in FIG. 2 via a bus or the like.

[0019] The CPU 11 is an example of a processor and controls all the components of the self-service POS terminal 1. The ROM 12 stores various programs. The RAM 13 is a workspace for storing programs and various data. The CPU 11, the ROM 12, and the RAM 13 constitute a control unit 100, which is an example of a computer.

[0020] The storage unit 14 has a storage medium such as a hard disk drive (HDD) or flash memory, and maintains its stored contents even when the power is turned off. The storage unit 14 stores various programs and setting information that can be executed by the CPU 11. The storage unit 14 also stores a product master 141, a character management table 142, etc.

[0021] The product master 141 is a data table or database that stores information about products for sale. Fig. 3 is a diagram showing an example of the data configuration of the product master 141. As shown in Fig. 3, the product master 141 associates each product with an identifiable product code and stores information (hereinafter also referred to as product information) such as the product name, abbreviation, additional information, and price of the product identified by the product code.

[0022] Here, the product code is product identification information such as a JAN code. Each product sold in a store is affixed with a code symbol such as a barcode or two-dimensional code that holds the product code of the product. Furthermore, the product can be identified by reading the product code from the code symbol affixed to the product.

[0023] The product name is information that details the product name, such as the product's official name. The abbreviated name is information that simplifies the product name, such as the product's abbreviation, alias, or nickname. For example, the abbreviated name may be the product category or part of the product name written in hiragana. The additional information stores additional information related to the product. For example, if the product is an apparel product such as clothing, the size of the product, etc. is stored as additional information. The price is information that indicates the unit price of the product.

[0024] The data structure of the product master 141 is not limited to the example in Fig. 3. For example, the product master 141 may store product information including image data representing product characteristics, weight, etc. The product master 141 also stores the above-mentioned product information for shopping bags sold in the store.

[0025] The character management table 142 is a data table or database that stores information about character images of characters to be presented to the user. Here, the character images are images or motion graphics that resemble animals, robots, imaginary creatures, etc.

[0026] Fig. 4 is a diagram showing an example of the data configuration of the character management table 142. As shown in Fig. 4, the character management table 142 stores information such as a character ID, a basic image, and a trigger operation image.

[0027] The character ID is identification information for identifying a character. The basic image stores a character image to be displayed at a fixed, predetermined position within various screens. For example, the basic image may be a combination of the type of screen on which the character image is displayed, the character image to be displayed on that screen, and the position at which the character image is to be placed within that screen. The basic image may also store an image of the background on which the character image is placed.

[0028] The trigger operation image is an example of a notification image. The trigger operation image stores a character image to be displayed when a predetermined operation is performed. Specifically, the trigger operation image may associate the type of operation that displays the character image with the character image to be displayed when that type of operation is performed. Here, the operation type can be set arbitrarily. For example, the operation type may be a "reading operation" that reads a code symbol (product code). Furthermore, the character image associated with one operation type is not limited to one, and may be multiple. In this case, the display order, priority, etc. may be added to the multiple character images.

[0029] The data configuration of the character management table 142 is not limited to the example shown in Fig. 4. For example, the character management table 142 may store voice information corresponding to a character identified by a character ID.

[0030] Returning to Fig. 2, the audio output unit 15 is an audio output device such as a speaker. The audio output unit 15 outputs the voice of a character and the like under the control of the control unit 100. The communication unit 16 is a communication interface connectable to a network such as a LAN (Local Area Network) (not shown). The communication unit 16 communicates with an external device such as a store server installed in a store or an electronic payment server that provides an electronic payment service, for example, via the network.

[0031] Next, the functional configuration of the self-service POS terminal 1 will be described with reference to Fig. 5. Fig. 5 is a diagram showing an example of the functional configuration of the self-service POS terminal 1. As shown in Fig. 5, the self-service POS terminal 1 includes an operation reception unit 111, a display control unit 112, and a sales data processing unit 113 as functional components.

[0032] Some or all of the functional configuration of the self-service POS terminal 1 may be a software configuration realized by cooperation between a processor (e.g., CPU 11) of the self-service POS terminal 1 and a program stored in a memory (e.g., ROM 12, storage unit 14). Also, some or all of the functional configuration of the self-service POS terminal 1 may be a hardware configuration realized by a dedicated circuit or the like mounted on the self-service POS terminal 1.

[0033] The operation reception unit 111 receives user operations via the operation unit 82. Specifically, the operation reception unit 111 receives operations on various screens displayed on the display unit 81, and notifies the CPU 11 of the received operation contents.

[0034] The display control unit 112 controls the display unit 81 to display various screens. For example, the display control unit 112 cooperates with the sales data processing unit 113 to cause the display unit 81 to display a screen for supporting the purchase of a product.

[0035] The sales data processing unit 113 is an example of a registration unit, a checkout unit, and a control unit. The sales data processing unit 113 executes various processes to support the purchase of products by cooperating with the hardware and other functional units of the device itself. Specifically, when the sales data processing unit 113 receives an operation to start a transaction via the operation unit 82, it starts processing sales data related to one transaction.

[0036] When a transaction is initiated, the sales data processing unit 113 enables the code reading unit 5 to read the product code and waits for the product code to be read. Each time the code reading unit 5 reads a product code, the sales data processing unit 113 identifies the product corresponding to the product code from the product master 141 and executes a registration process to store the identified product code or product information in the RAM 13 or the like. When the sales data processing unit 113 receives a transaction start instruction via the operation unit 82, it calculates the total price of the products registered up to that instruction and executes a transaction process to settle the transaction with the amount paid via the cashier unit 4 or the like. During this transaction process, the sales data processing unit 113 dispenses any change from the cashier unit 4 and causes the printing unit 7 to issue a receipt on which product information, the total price, the payment amount, and the like are printed. When a plastic bag is sold, the sales data processing unit 113 registers the plastic bag to be purchased by the user after receiving a transaction start instruction, and executes the transaction process by including the price of the plastic bag in the total price.

[0037] Furthermore, the sales data processing unit 113 cooperates with the display control unit 112 to provide a user interface for supporting product purchases during the above-described sales data processing via the display unit 81. Furthermore, the sales data processing unit 113 of this embodiment causes the display unit 81 to display a user interface that assumes that the target users operating the self-service POS terminal 1 are parents and children or children.

[0038] Hereinafter, with reference to FIGS. 6 to 16, the screens that the sales data processing unit 113 causes to be displayed on the display unit 81 will be described.

[0039] First, the sales data processing unit 113 displays the screen SCa of Fig. 6 as an initial screen on the display unit 81. Fig. 6 is a diagram showing an example of a screen displayed on the display unit 81 of the self-service POS terminal 1, and shows a screen for instructing the start of a transaction.

[0040] A message MSa is displayed on the screen SCa to explain how to start a transaction. The screen SCa also has a start button BTa, which is an operator for instructing the start of a transaction. Here, the message MSa is written in simple sentences using hiragana etc. to suit the target user. The start button BTa is displayed in a position, shape, size, etc. that makes it easy for the user to operate. An explanatory text (start) written in simple sentences using hiragana etc. is superimposed on the start button BTa. Note that the various messages and operators are displayed with a similar concept on the screens SCb to SCh and SCj to SCk described below.

[0041] In addition, character images CHa and CHb, which are examples of basic images, are displayed near the start button BTa. The character images CHa and CHb are arranged on either side of the start button BTa to emphasize the start button BTa.

[0042] The character ID of the character displayed on screen SCa and the subsequent screens may be a predetermined default character ID or may be determined randomly. Furthermore, as will be described later, the user may be able to select the character (character ID). Furthermore, the sales data processing unit 113 may perform processing such as outputting a message MSa or other text in a voice corresponding to the displayed character (the same applies to the subsequent screens).

[0043] When the sales data processing unit 113 receives an operation of the start button BTa, it determines that an instruction to start the transaction has been issued, and causes the display unit 81 to display the screen SCb of Fig. 7. Fig. 7 is a diagram showing an example of a screen displayed on the display unit 81 of the self-service POS terminal 1, and shows a screen for confirming whether or not a shopping bag is available.

[0044] A message MSb for asking whether or not a plastic bag is available is displayed on the screen SCb. A character image CHc, which is an example of a basic image, is displayed near the message MSb.

[0045] Furthermore, selection buttons BTb to BTd are displayed on screen SCb. Selection buttons BTb to BTd are operators for selecting whether or not a plastic bag is provided and the type of plastic bag. Selection button BTb is an operator for selecting a 28 yen "paper bag," which is one type of plastic bag. Selection button BTc is an operator for selecting a 5 yen "rejibukuro," which is one type of plastic bag. Selection button BTd is an operator for indicating that a plastic bag is not required. Here, selection buttons BTb and BTc are associated with, for example, the product code of the corresponding plastic bag, and the product code of the operated operator is input.

[0046] When the sales data processing unit 113 receives an operation of the selection button BTb or BTc, it displays the number of times the button was operated as the number of purchases superimposed on the selected button. Figure 7 shows an example in which a 5 yen "Register Bag" was operated once, and the number of purchases "1" is displayed superimposed on the selection button BTc.

[0047] Furthermore, the sales data processing unit 113 displays the number of plastic bags to be purchased as instructed by operating the selection buttons BTb and BTc, and the total price, in a display field DFa displayed below the selection buttons BTb-BTd. Specifically, the sales data processing unit 113 totals the number of plastic bags to be purchased as instructed by operating the selection buttons BTb and BTc, and displays the total number of purchases in the display field DFa. Furthermore, the sales data processing unit 113 multiplies the price of each type of plastic bag by the number of purchases, and displays the total price of the multiplication results in the display field DFa.

[0048] When the selection button BTc is selected, the sales data processing unit 113 displays information indicating that the selection button BTc has been selected, superimposed on the selection button BTc, and sets the total points and total amount in the display field DFa to 0.

[0049] Furthermore, screen SCb is provided with operation buttons BTe and BTf. Operation button BTe is an operator for instructing transition to the next screen. When sales data processing unit 113 accepts operation of operation button BTe, it registers the shopping bag selected using selection buttons BTb and BTc as a product to be purchased by the user, and causes display unit 81 to display screen SCc shown in Fig. 8. Note that when selection button BTd is selected, sales data processing unit 113 causes display unit 81 to display screen SCc of Fig. 8 without performing registration processing.

[0050] The operation button BTf is an operator for instructing to stop the transaction. When the sales data processing unit 113 receives an operation of the operation button BTf, it stops the transaction and returns the display to the screen SCa.

[0051] FIG. 8 is a diagram showing an example of a screen displayed on the display unit 81 of the self-checkout POS terminal 1, and shows a screen for providing guidance on how to read a commodity.

[0052] On the screen SCc, a message MSc for instructing how to read the code symbol attached to the product is displayed, along with an image Ga for instructing how to read the code symbol. Also, a character image CHd, which is an example of a basic image, is displayed near the message MSc.

[0053] The image Ga displays an illustration, animation, or the like, which shows the user bringing a code symbol attached to a product close to the reading window 51 of the code reading unit 5. When the user brings the code symbol attached to the product close to the reading window 51, the product code stored in the code symbol is read by the code reading unit 5. When the product code is read by the code reading unit 5, the sales data processing unit 113 performs a product registration process based on the product code. Furthermore, the sales data processing unit 113 notifies the user that reading by the code reading unit 5 has been completed by outputting a reading sound such as a "beep" from the audio output unit 15. Furthermore, the sales data processing unit 113 displays a screen SCd shown in FIG. 9 on the display unit 81 to notify the user that reading by the code reading unit 5 has been completed.

[0054] FIG. 9 is a diagram showing an example of a screen displayed on the display unit 81 of the self-checkout POS terminal 1, and shows the screen displayed when the product code is read.

[0055] As shown on screen SCd, when the code reading unit 5 reads a product code, the sales data processing unit 113 determines that a reading operation has been performed by the user, and displays a character image CHe corresponding to the operation. The character image CHe is an example of a trigger operation image stored in association with the product code reading operation. This trigger operation image shows an example in which an onomatopoeia (written in hiragana as "pi") that matches the reading sound of the code reading unit 5 is displayed together with the character image. The sales data processing unit 113 notifies the user that reading by the code reading unit 5 has been performed by displaying the character image CHe on the display unit 81.

[0056] Here, in order to enhance visibility and entertainment value, the character image CHe is displayed for a predetermined short time in a size that occupies more than half of the screen SCd. In other words, the character image CHe is displayed for one moment (for example, one second) when the code symbol is read by the code reading unit 5.

[0057] In this way, the sales data processing unit 113 can improve the operability and entertainment value of the reading operation by displaying a large character image CHe at the timing when a product reading operation is performed. For example, even if a child is an infant or toddler and the parent is operating the device, the child's attention can be directed to the character image CHe, so the product reading operation can be performed smoothly.

[0058] After displaying the character image CHe for a predetermined time, the sales data processing unit 113 erases the display of the character image CHe and causes the display unit 81 to display a screen SCe shown in FIG.

[0059] FIG. 10 is a diagram showing an example of a screen displayed on the display unit 81 of the self-checkout POS terminal 1, and shows the screen displayed after the product code is read.

[0060] A message MSd is displayed on the screen SCe to guide the user to register additional products and start the checkout process. Information about the products registered in the most recent registration process is also displayed in a display field DFb on the screen SCe. A character image CHf, which is an example of a basic image, is displayed near the display field DFb. Here, the character image CHf is depicted as if it is speaking a line in the speech bubble-shaped display field DFb.

[0061] The display field DFb displays the abbreviation and price included in the product information of the most recently registered product. In Figure 10, the abbreviation of the most recently registered product is "Kooto" and its price is "1758" yen. Hereinafter, the display mode of the screen in which the product name is displayed in abbreviation is also referred to as the "simplified display screen."

[0062] Furthermore, if the product information includes additional information, the content of that additional information is displayed in the display field DFb. In Fig. 10, the content of the additional information is represented by a mark MKa added to the upper left of the display field DFb, indicating that the size is 95 cm. This allows the user to easily check the content of the product most recently scanned by looking at the display field DFb.

[0063] The screen SCe also has a display field DFb for displaying the total number of registered items and the total price. The sales data processing unit 113 calculates the total number of registered items and the total price of the items registered from the start of the transaction to the present, and displays them in the display field DFb. The example in FIG. 10 shows an example in which a total number of 2 items and a total price of 1,763 yen are displayed in the display field DFb, based on the price of the first registered shopping bag (rejibukuro) of 5 yen and the price of the next registered abbreviation "koto" of 1,758 yen. This allows the user to easily check the total number of registered items and the total price of the items that have been scanned so far by looking at the display field DFc.

[0064] Furthermore, the screen SCe is provided with an operation button BTg, an operation button BTh, and an operation button BTi.

[0065] The operation button BTg is an operator for instructing the start of a transaction. A character image CHg, which is an example of a basic image, is displayed near the operation button BTg along with a message guiding the user to start the transaction.

[0066] Furthermore, the operation button BTh is an operator for instructing to cancel the most recently registered product. When the sales data processing unit 113 receives an operation of the operation button BTh, it erases the product information etc. of the most recently registered product, and then returns the display to the previous screen (screen SCc in FIG. 8). The operation button BTi is an operator for checking the products that have been registered up to now. Examples of screens that are displayed when the operation button BTg and the operation button BTi are operated will be described later.

[0067] As stated in the message MSd, while the screen SCe is displayed, the user can similarly bring the code symbol attached to the product close to the reading window 51 to additionally register the product. When the code reading unit 5 reads the product code, the sales data processing unit 113 performs product registration processing based on the product code and issues a reading sound. Furthermore, the sales data processing unit 113 displays the screen SCf shown in FIG. 11 on the display unit 81 to notify the user that the code reading unit 5 has read the code.

[0068] FIG. 11 is a diagram showing an example of a screen displayed on the display unit 81 of the self-checkout POS terminal 1, and shows the screen displayed when the product code is read.

[0069] 9, a large character image CHh is displayed on the screen SCf to notify that reading has been performed by the code reading unit 5. The character image CHh is an example of a trigger operation image stored in association with the reading operation on the code reading unit 5.

[0070] Here, the sales data processing unit 113 displays the character image CHh in a display format different from the previously displayed character image CHe. For example, as shown in FIG. 11, the sales data processing unit 113 rotates or enlarges (or reduces) the character image CHe to display the trigger operation image in a display format different from the previously displayed trigger operation image. Also, for example, the sales data processing unit 113 changes the display color of part or all of the character image CHe to display the trigger operation image in a display format different from the previously displayed trigger operation image. Furthermore, if multiple trigger operation images are stored in association with product code reading operations, the sales data processing unit 113 may read out and display a trigger operation image different from the previously displayed trigger operation image. Furthermore, the sales data processing unit 113 may output the reading sound of the code reading unit 5 in a voice or tone different from the previously output reading sound.

[0071] In this way, by changing the notification method each time a product is read, the sales data processing unit 113 can draw attention and awareness to the repetitive reading operation, which can tend to become monotonous, thereby promoting the reading operation.

[0072] After displaying the character image CHh for a predetermined time, the sales data processing unit 113 erases the display of the character image CHh and causes the display unit 81 to display a screen SCg shown in FIG.

[0073] FIG. 12 is a diagram showing an example of a screen displayed on the display unit 81 of the self-checkout POS terminal 1, and shows the screen displayed after the product code is read.

[0074] Screen SCg has the same screen configuration as screen SCe in FIG. 10 described above. Here, the display field DFb displays the abbreviation and price included in the product information of the most recently registered product, as before. In FIG. 12, the abbreviation of the most recently registered product is "Tee Shirt" and its price is 438 yen. The content of the additional information included in the product information is represented by mark MKb, indicating that the size is 90 cm. Furthermore, as the product is additionally registered, the total points and total price in display field DFc are updated and displayed.

[0075] In this way, even when multiple products are registered, the sales data processing unit 113 displays the abbreviation and price of the most recently registered product. This makes it easy for a child, for example, to check the product that the child most recently caused the code reading unit 5 to read. Hereinafter, the display mode of the screen that displays only the most recently registered product, as described in Figs. 10 and 12, is also referred to as the "single product display screen."

[0076] Furthermore, when the sales data processing unit 113 receives an operation of the operation button BTi on the screen SCg (or screen SCe), it causes the display unit 81 to display a screen SCh shown in FIG.

[0077] FIG. 13 is a diagram showing an example of a screen displayed on the display unit 81 of the self-checkout POS terminal 1, and shows a screen for checking registered products.

[0078] The screen SCh displays a message MSe to guide the user to register additional products and begin checkout. The screen SCh also has a list display field LDa, which displays a list of all registered products in the order they were registered, with their abbreviations and prices associated with each other. Hereinafter, the display mode of the screen that displays a list of all registered products will also be referred to as the "list display screen."

[0079] The list display field LDa in Figure 13 shows an example in which the product abbreviation and price are displayed along with a number indicating the order in which the product was registered. The most recently registered product, "Tee Shirt," is displayed in a different color to distinguish it from other products. If additional information is included in the product information, marks MKa and MKb indicating the content of the additional information are displayed in association with the corresponding product.

[0080] This allows the user to easily check the products that have been registered so far by looking at the list display field LDa. Also, the user can easily distinguish the most recently registered product among the products that have been registered so far.

[0081] In addition, below the list display field LDa, a display field DFd is provided for displaying the total number of items and the total price of the products that have been registered so far. The same total number of items and total price as those in the display field DFc are displayed in the display field DFd. By looking at the display field DFd, the user can easily check the number of items and the total price of the products that have been registered so far.

[0082] Furthermore, the screen SCh is provided with operation buttons BTj, BTk, and BTl.

[0083] Like operation button BTg, operation button BTj is an operator for instructing the start of a transaction. A character image CHh, which is an example of a basic image, is displayed near operation button BTj along with a message guiding the user to start the transaction.

[0084] The operation button BTk is an operator for returning to the single item display screen of the most recently registered product. When the sales data processing unit 113 accepts the operation of the operation button BTk, it returns the display to the screen SCg of FIG.

[0085] The operation button BT1 is an operator for instructing the display of product details. The operation button BT1 is intended to be operated by, for example, a parent of a child. When the sales data processing unit 113 receives an operation of the operation button BT1, it causes the display unit 81 to display the screen SCi of FIG. 14.

[0086] FIG. 14 is a diagram showing an example of a screen displayed on the display unit 81 of the self-checkout POS terminal 1, and shows a screen for checking details of registered products.

[0087] Screen SCi displays message MSf to guide the user through the additional product registration and the start of checkout, similar to the above-mentioned screens SCg, SCh, etc. However, since this screen is intended for use by adults, message MSf is written in normal notation, including kanji characters, unlike the other messages described so far.

[0088] The screen SCi also has a list display field LDb, which displays the product name and price of each product registered so far in the order they were registered. Below the list display field LDb, a display field DFe is provided for displaying the total number of products and the total price of the products registered so far.

[0089] Here, the content displayed in the list display field LDb is the same as the list display field LDa on the screen SCh described above, except that the product name has been changed from an abbreviation to the official product name. The content displayed in the display field DFe is also the same as the display field DFd on the screen SCh described above, except that the furigana readings have been removed from the display field DFd. Hereinafter, the display mode of the screen in which the product name is displayed as the product name will also be referred to as the "detailed display screen."

[0090] Furthermore, the screen SCi is provided with an operation button BTm and an operation button BTn. Note that the explanation displayed on the operation button BTm is changed from the hiragana notation on the operation button BTj to kanji notation.

[0091] Like the operation button BTj, the operation button BTm is an operator for instructing the start of a transaction. Similar to the character image CHh, a character image CHi is displayed near the operation button BTm to guide the user in operating the operation button BTm.

[0092] The operation button BTn is an operator for returning to the single item display screen of the most recently registered product. When the sales data processing unit 113 accepts the operation of the operation button BTn, it returns the display to the screen SCg of Fig. 12. Note that the operation button BTn may also be an operator for returning to the previous screen.

[0093] In addition, when the sales data processing unit 113 receives an operation on an operator for instructing the start of a transaction, such as the operation button BTm on screen SCi, the operation button BTg on screen SCg (see Figure 12), or the operation button BTj on screen SCh (see Figure 13), the sales data processing unit 113 displays the screen SCj shown in Figure 15 on the display unit 81.

[0094] Figure 15 is a diagram showing an example of a screen displayed on the display unit 81 of the self-service POS terminal 1, and shows the screen displayed when a payment instruction is given. Note that Figure 15 shows an example in which payment for goods is made by electronic payment using a code symbol (hereinafter also referred to as code payment), but the payment method is not limited to this.

[0095] The screen SCj displays a message MSg to guide the user in reading the code symbol related to code payment. The screen SCj also displays an image Gb to guide the user in reading the code symbol displayed on the user's terminal device. The image Gb displays an illustration or animation representing a smartphone, which is an example of the user's terminal device, and the code symbol displayed on the display screen of the smartphone. In addition, a character image CHj, which is an example of a basic image, is displayed near the smartphone shown in the image Gb, along with a message to guide the user in reading the code symbol.

[0096] The screen SCj also has a display field DFf for displaying the total number of items and the total price of the products that have been registered so far. The display field DFf displays the total number of items and the total price of the registered products, similar to the display field DFe, etc.

[0097] Furthermore, the screen SCj is provided with an operation button BTo. The operation button BTo is an operator for returning to the single item display screen of the most recently registered product. When the sales data processing unit 113 receives an operation of the operation button BTo, it returns the display to the screen SCg of Fig. 12. Note that the operation button BTn may also be an operator for returning to the immediately previous screen.

[0098] When the code reading unit 5 reads the code symbol for code payment on screen SCj, the sales data processing unit 113 executes a transaction process to settle the total amount displayed in the display field DFe based on the electronic payment information contained in the code symbol. Then, when the transaction process is completed, the sales data processing unit 113 issues a receipt from the printing unit 7 and displays screen SCk of Fig. 16 on the display unit 81. Note that the sales data processing unit 113 may also display a trigger operation image similar to Figs. 9 and 11, etc., when it reads the code symbol for code payment.

[0099] FIG. 16 is a diagram showing an example of a screen displayed on the display unit 81 of the self-checkout POS terminal 1, and shows the screen displayed when the transaction is completed.

[0100] A character image CHk, which is an example of a basic image, is displayed on the screen SCk. For example, the character image CHk is represented by an illustration or animation showing a waving motion, and is displayed together with a message informing the user of the next use. The screen SCk also displays a message MSh prompting the user to check the receipt. A character image CHl, which is an example of a basic image, is also displayed near the message MSh.

[0101] As a result, the sales data processing unit 113 can make the user aware that the transaction has been completed by looking at the screen SCk. Also, the sales data processing unit 113 can make the user aware of the presence of a receipt by looking at the screen SCk. Note that if the receipt is output in the form of an electronic receipt, the sales data processing unit 113 may display a message on the screen SCk prompting the user to check the electronic receipt.

[0102] As described above, the sales data processing unit 113 displays character images that attract the interest of children such as infants and small children on each screen of a transaction related to the purchase of a product. As a result, when a parent is operating the self-service POS terminal 1 together with an infant or small child, for example, the sales data processing unit 113 can direct the child's attention to the screen, thereby improving operability in proceeding with the transaction.

[0103] Furthermore, the sales data processing unit 113 displays character images in association with operators required to proceed with a transaction, such as operators that instruct the start of a transaction or the start of accounting. As a result, when, for example, a parent and child operate the self-service POS terminal 1 together or a child operates the self-service POS terminal 1, the sales data processing unit 113 can direct the child's attention to the operators with the character images attached, thereby encouraging the child to operate the terminal.

[0104] Furthermore, when a predetermined operation, such as a product reading operation, is performed, the sales data processing unit 113 displays a character image (trigger operation image) corresponding to the operation in a size that occupies more than half of the screen. As a result, when, for example, a parent and child operate the self-service POS terminal 1 or a child operates the self-service POS terminal 1, the sales data processing unit 113 can explicitly notify the child that the operation has been accepted, thereby improving operability. Furthermore, by displaying the trigger operation image, the sales data processing unit 113 can increase the child's interest in and entertainment value of the product reading operation, thereby facilitating and promoting the reading operation.

[0105] The character of the character image displayed on each of the above-mentioned screens may be configured to be selectable by the user. For example, on the screen SCa of Fig. 6, the sales data processing unit 113 changes the character displayed as the character image CHa by switching the character ID in a predetermined order or random order on the condition that the character image CHa is touched. Also, the sales data processing unit 113 sets the character ID selected at the time the start button BTa is operated as the display target, and displays the character image corresponding to the character ID on the subsequent screen.

[0106] Moreover, the sales data processing unit 113 may prompt the user to select a character by displaying, for example, a screen SC1 shown in FIG. 17 on the display unit 81 instead of the screen SCa of FIG.

[0107] FIG. 17 is a diagram showing an example of a screen displayed on the display unit 81 of the self-checkout POS terminal 1, and shows another example of a screen for instructing the start of a transaction.

[0108] A message MSi prompting the player to select a character is displayed on the screen SCl. Also displayed on the screen SCl are selection buttons BTp to BTr representing characters with each character ID. The selection buttons BTp to BTr are controls for selecting a character.

[0109] When any one of the selection buttons BTp to BT is operated, the sales data processing unit 113 sets the character ID of the character corresponding to the operated selection button as the display object. Then, the sales data processing unit 113 starts the transaction and displays the character image corresponding to the character ID set as the display object on the subsequent screens.

[0110] Although the above describes examples of screens for target users such as parents and children, the display modes of the various screens are not limited to those for children, and may be configured to be switchable to a display mode for adults. Specifically, the sales data processing unit 113 has two display modes, one for children and one for adults, and displays the various screens described above using either one of the display modes.

[0111] In this case, the initial screen is provided with an operation button BTs for switching to an adult display mode, as shown on screen SC1 in Fig. 17, for example. When the sales data processing unit 113 accepts the operation of the operation button BTs, it registers and checks out the product using, for example, a screen that omits the display of character images. Furthermore, in the adult display mode, when a product is registered, the sales data processing unit 113 may display the registered product using a list display screen such as the above-mentioned screen SCi (Fig. 14) without using the single product display screen. Furthermore, in the adult display mode, it is preferable to use a detailed display screen that displays the product name by product name. In addition, in the display mode for adults, it is preferable that various messages and explanatory text displayed on the controls be in normal notation, including kanji characters, etc. Furthermore, the display mode for adults may use a display layout different from that used in the display mode for children.

[0112] Furthermore, the display mode may be switched not only from the initial screen but also from any screen displayed during a transaction. In this case, the sales data processing unit 113 may provide an operator for switching from the children's display mode to the adult display mode (or from the adult display mode to the children's display mode) on each of the screens described in Figures 7 to 15, and switch the display mode in response to an operation on the operator.

[0113] This allows for an improvement in operability and convenience when a parent and child operate the self-service POS terminal 1, as the display mode for children and the display mode for adults can be switched as appropriate.

[0114] Next, a description will be given of an example of sales data processing performed by the self-service POS terminal 1. Fig. 18 is a flowchart showing an example of sales data processing performed by the self-service POS terminal 1. Note that this processing shows an example of processing when a display mode for children is selected.

[0115] First, the sales data processing unit 113 displays, for example, a screen SCa (see FIG. 6) or a screen SC1 (see FIG. 17) on the display unit 81, thereby prompting the user to select a character (step S11). If no character is selected, the sales data processing unit 113 sets the character ID of a predetermined default character as the display target (step S12), and proceeds to step S14.

[0116] Furthermore, if a character is selected in step S11 (step S11; Yes), the sales data processing unit 113 sets the character ID of the selected character as the display target (step S13), and proceeds to step S14.

[0117] Next, the sales data processing unit 113 determines whether or not a plastic bag is available by, for example, displaying screen SCb (see FIG. 7) on the display unit 81 (step S14). If an instruction is received that a plastic bag is not required (step S14; No), the sales data processing unit 113 proceeds to step S16.

[0118] Furthermore, if a plastic bag is selected in step S14 (step S14; Yes), the sales data processing unit 113 registers the selected plastic bag as a commodity (step S15), and proceeds to step S16.

[0119] Next, the sales data processing unit 113 causes the display unit 81 to display a guidance screen for guiding the user in reading the product (step S16). For example, the sales data processing unit 113 causes the display unit 81 to display a screen SCc (see FIG. 8).

[0120] Next, the sales data processing unit 113 waits until the product code is read by the code reading unit 5 (step S17; No → step S27; No). When the product code is read by the code reading unit 5, the sales data processing unit 113 causes the display unit 81 to display a trigger operation image corresponding to the product code reading operation (step S18). For example, the sales data processing unit 113 causes the display unit 81 to display a screen SCd (see FIG. 9).

[0121] Next, the sales data processing unit 113 performs a registration process for the product identified by the read product code (step S19), and causes the display unit 81 to display a product display screen showing the abbreviation of the product, etc. (step S20). For example, the sales data processing unit 113 causes the display unit 81 to display the screen SCe (see FIG. 10).

[0122] Next, the sales data processing unit 113 determines whether or not an operation to instruct confirmation of the registered product has been accepted (step S21). For example, the sales data processing unit 113 determines whether or not the operation button BTi on the screen SCe (see FIG. 10) has been operated. If the operation has not been accepted (step S21; No), the sales data processing unit 113 proceeds to step S27.

[0123] Furthermore, when the sales data processing unit 113 receives an instruction to check the registered products (step S21; Yes), it causes the display unit 81 to display a list display screen that displays a list of the abbreviations of the products registered so far in the order in which they were registered (step S22). For example, the sales data processing unit 113 causes the display unit 81 to display a screen SCh (see FIG. 13).

[0124] Next, the sales data processing unit 113 determines whether an instruction to return to the single item display screen has been given. For example, the sales data processing unit 113 determines whether the operation button BTk on the screen SCh (see FIG. 13) has been operated. If an instruction to return to the single item display screen has been given (step S23; Yes), the sales data processing unit 113 returns the process to step S20, thereby displaying the single item display screen.

[0125] Furthermore, if an instruction to return to the single item display screen is not given in step S23 (step S23; No), the sales data processing unit 113 determines whether an instruction to display product details has been given (step S24). For example, the sales data processing unit 113 determines whether the operation button BT1 on the screen SCh (see FIG. 13) has been operated. Here, if an instruction to display product details has not been given (step S24; No), the sales data processing unit 113 proceeds to step S27.

[0126] Furthermore, if an instruction to display product details is given in step S24 (step S24; Yes), the sales data processing unit 113 causes the display unit 81 to display a screen listing the product names and the like of products registered so far in the order in which they were registered (step S25). For example, the sales data processing unit 113 causes the display unit 81 to display a screen SCi (see FIG. 14).

[0127] Next, the sales data processing unit 113 determines whether an instruction to return to the single item display screen has been given. For example, the sales data processing unit 113 determines whether an operation button BTn on the screen SCi (see FIG. 14) has been operated. If an instruction to return to the single item display screen has been given (step S26; Yes), the sales data processing unit 113 returns the process to step S20, thereby displaying the single item display screen.

[0128] Furthermore, if an instruction to return to the single item display screen is not given in step S26 (step S26; No), the sales data processing unit 113 shifts the process to step S27.

[0129] In step S27, the sales data processing unit 113 determines whether an operation to instruct the start of a transaction has been accepted (step S27). If an instruction to start a transaction has not been accepted (step S27; No), the sales data processing unit 113 returns the process to step S17.

[0130] On the other hand, if an operation to start the transaction is accepted in step S27 (step S27; Yes), the sales data processing unit 113 executes the transaction process to settle the total amount of the products registered up to that point with the amount paid by the user (step S28), and ends this process.

[0131] As described above, the self-service POS terminal 1 of this embodiment displays various screens on the display unit 81 to assist the user in performing operations during a transaction related to the purchase of a product, and when the user performs a predetermined operation, displays a trigger operation image corresponding to that operation on the display unit 81. The self-service POS terminal 1 also displays the trigger operation image in a size that occupies more than half of the screen.

[0132] As a result, when, for example, a parent and child operate the self-service POS terminal 1 together or a child operates the self-service POS terminal 1, the self-service POS terminal 1 can explicitly notify the child that the operation has been accepted, thereby improving operability. Furthermore, by displaying the trigger operation image, the sales data processing unit 113 can increase the interest and entertainment value of children in the product reading operation, thereby facilitating and promoting the reading operation.

[0133] The above-described embodiment can be modified as needed by partially changing the configuration or functions of each of the above-described devices. Therefore, several modifications of the above-described embodiment will be described below as other embodiments. The following mainly focuses on differences from the above-described embodiment, and detailed descriptions of commonalities with the content already described will be omitted. The modifications described below may be implemented individually or in appropriate combination.

[0134] (Variation 1) In the above embodiment, the code reading unit 5 of the self-service POS terminal 1 reads the product code stored in the code symbol. However, the method for reading (obtaining) the product code is not limited to this.

[0135] For example, conventionally, wireless tags such as RFID tags storing product codes are attached to products, and the product codes are read from the wireless tags attached to each product at once using a reading device such as an RFID reader (hereinafter also referred to as a wireless tag reading device). Therefore, in this modified example, a configuration in which the code reading unit 5 is a wireless tag reading device will be described.

[0136] When the code reading unit 5 is a wireless tag reading device, the code reading unit 5 is provided, for example, on the placement portion of the basket stand 9 shown in Fig. 1 or on one side of the self-service POS terminal 1 on which the basket stand 9 is installed. By providing the code reading unit 5 in such a position, it is possible to efficiently read the product codes from the products placed in the basket.

[0137] Furthermore, when the code reader 5 is a wireless tag reader, it is possible to read a plurality of product codes at once, so it is preferable to change the screen displayed during the transaction.

[0138] Specifically, the sales data processing unit 113 displays on the display unit 81 a message MSc and an image Ga on the screen SCc (see Figure 8) that provides instructions on how to read the product code, guiding the user to place the basket containing the product on the basket stand 9.

[0139] In addition, in response to the reading operation by the code reading unit 5, the sales data processing unit 113 causes the display unit 81 to display a screen SCm shown in FIG.

[0140] FIG. 19 is a diagram showing an example of a screen displayed on the display unit 81 of the self-checkout POS terminal 1, and shows the screen displayed when the product code is read.

[0141] As shown on screen SCm, the sales data processing unit 113 is triggered by the code reading unit 5 reading an operation of a code symbol or a product code, i.e., a reading operation by the user, to display a character image CHm corresponding to that operation. The character image CHm is an example of a trigger operation image stored in association with a reading operation on the code reading unit 5. In such a trigger operation image, numbers corresponding to the number of product codes read by the code reading unit 5 are displayed in a balloon, either all at once or sequentially. By displaying the character image CHm on the display unit 81, the sales data processing unit 113 notifies the user that reading has been performed by the code reading unit 5 and the number of products (product codes) that have been read.

[0142] In this case, the sales data processing unit 113 may change the reading sound of the code reading unit 5 according to the number of product codes read by the code reading unit 5. For example, the sales data processing unit 113 may output a voice corresponding to a character counting up the number of product codes. Also, for example, the sales data processing unit 113 may change the pitch (scale) or tone of the sound according to the number of product codes read by the code reading unit 5.

[0143] This allows the sales data processing unit 113 to add entertainment value to the display on the screen when a child performs the product reading operation, thereby improving operability when a child becomes a user of the self-service POS terminal 1.

[0144] The product confirmation screen displayed after the product code is read may be the single product display screen described above, or the list display screen described with respect to the screen SCh in FIG.

[0145] The programs executed by each device in the above-described embodiments are provided in a state where they are pre-installed in a ROM, a storage unit, etc. The programs executed by each device in the above-described embodiments may be provided by being recorded in an installable or executable format on a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a digital versatile disk (DVD).

[0146] Furthermore, the programs executed by each device in the above-described embodiments may be stored on a computer connected to a network such as the Internet and provided by being downloaded via the network. Also, the programs executed by each device in the above-described embodiments may be provided or distributed via a network such as the Internet.

[0147] Although the embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments and their modifications can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the inventions and their equivalents as defined in the claims.
