Description

[Technical Field]

[0001] The present invention relates to a product sales data processing device that can suitably register products with multiple sales modes. [Background technology]

[0002] Conventionally, there are so-called full-self-service POS devices that allow customers to register the products they wish to purchase and then process the payment themselves. This type of full-self-service POS device is connected to a scale, and after registering the product, the scale measures the product's mass and compares the measured mass with a pre-registered reference mass for that product, thereby confirming (verifying) that the registered product is correct.

[0003] However, when checking the product weight using a scale, even if the product is the correct product, there may be a difference of more than a specified value between the actual weighed mass and the reference mass. In such cases, an error may occur, which could make the registration process complicated.

[0004] In addition, there are cases where a scale is used to check whether the transfer of mass value from the placement section where unregistered products are placed to the placement section where registered products are placed is correct, or where the mass is added to the placement section of registered products, which is considered to be product registration and serves as a substitute for confirmation.

[0005] In addition, some sites do not install scales themselves in order to avoid the hassle of recovery operations due to the above errors and to increase the frequency of use of full-self-service POS devices, or due to space constraints. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-162208 Summary of the Invention [Problem to be solved by the invention]

[0007] However, as mentioned above, if product weight checks are not performed based on a pre-registered reference weight, or if scales are not installed, there is a risk of problems occurring with products that have different sales formats for the same product (for example, canned beer sold individually, in a pack of six, or in a case), and for which different barcodes are set and printed (or affixed) for each sales format.

[0008] For example, when trying to purchase a six-can pack, a user may accidentally (or fraudulently) scan the barcode printed on each can for individual sales, or even when purchasing a case, a barcode for individual sales may be printed on the case, and the user may accidentally (or fraudulently) scan this barcode.

[0009] In this way, when a case or six-pack is scanned with a single barcode, the store is forced to sell the case or six-pack at the price of the single item, which is a huge blow to the store.

[0010] Furthermore, with fully self-service POS devices, it is difficult to determine whether the incorrect registration operation when purchasing the above-mentioned product is fraudulent or an operational error. If it is an operational error, it will not leave a good impression on the customer, and if it is fraudulent, even if it is discovered, it may not be possible to pursue the fraud.

[0011] Furthermore, the above-mentioned operational error may occur when a store clerk (especially a new employee) performs the registration operation in a normal POS device.

[0012] The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a product sales data processing device that can prevent operational errors that may occur due to the existence of multiple sales modes. [Means for solving the problem]

[0013] The product sales data processing device of the present invention is characterized by comprising an input means for inputting product identification information, a storage means for storing the price for each sales mode of each product to be sold in association with the product identification information assigned to each sales mode of each product, and an output means for outputting information on the sales mode when there are multiple sales modes for the product related to the product identification information input by the input means. Here, the product identification information includes various barcodes such as JAN code, PLU code, ITF code, and QR code (registered trademark). Input means include a scanner that reads barcodes and preset keys that are pressed. Output means can output information in a variety of ways, including screen display, audio display, buzzer, rotating light, display on a receipt, and communication output to another device. This will prevent customers from selecting the wrong sales method for products that have multiple sales methods, and will also make it easier to detect and check potentially fraudulent operations.

[0014] In addition to the above features, the present invention is characterized in that when the information on the sales mode is output, the output is notified to other devices other than the device itself. The other devices include, for example, a surveillance monitor, other manned POS devices, and terminals at service counters. With this configuration, it is possible to inform and alert people other than the person operating the product sales data processing device that there are other sales modes for the product related to the product identification information input by the input means, thereby more effectively preventing mistakes in selecting the sales mode.

[0015] In addition to the above features, the present invention is characterized in that it has a display means for displaying a selectable selection of multiple sales modes when there are multiple sales modes for the product related to the product identification information input by the input means. This allows the operator to be informed that there are multiple sales modes, and also allows the operator to easily change the sales mode if it is incorrect.

[0016] In addition to the above features, the present invention is characterized in that the display means displays a confirmation means for confirming whether the sales mode of the product related to the product identification information input by the input means is correct or not. For example, the display means displays "Yes" and "No" buttons for confirming whether the sales mode of the product is correct or not. This configuration can more effectively prevent mistakes in selecting the sales mode.

[0017] In addition to the above features, the present invention is also characterized in that it includes a determination means for determining whether or not a mass detection means is connected, and when the determination means determines that the mass detection means is connected, the output means restricts the output of information about the sales mode. If a mass detection means is connected, the mass detection means can detect the mass of the product, thereby confirming the sales mode of the product and preventing the selection of the wrong sales mode. Therefore, the output operation of the sales mode information by the output means can be omitted. In other words, according to the present invention, optimal processing can be performed depending on whether or not a mass detection means is connected.

[0018] In addition to the above features, the present invention preferably further comprises a determination means for determining whether or not a mass detection means is connected, and when the determination means determines that the mass detection means is connected, the display means limits the selectable display of multiple sales modes. In this case, similarly to the above, the display of the multiple sales modes that can be selected by the display means may be omitted. That is, according to the present invention, optimal processing can be performed depending on whether or not the mass detection means is connected.

[0019] In addition to the above features, the present invention is characterized in that, if the sales mode of the product for which product identification information has been input by the input means is the sales mode for which the highest price is set among the multiple sales modes, the output means restricts the output of sales mode information. If the sales mode with the highest price set is selected, the store can easily determine that it is not an illegal selection, and the customer can easily notice if they have made a mistake because the price will be higher. Therefore, by limiting the output of the output means, it is possible to simplify the operation.

[0020] In addition to the above-mentioned features, the present invention is also preferably such that, if the sales mode of the product for which product identification information has been input by the input means is the sales mode for which the highest price is set among the plurality of sales modes, the display means limits the display of selectable sales modes from the plurality of sales modes. In this case, too, the operation can be simplified by limiting the display on the display means, as in the above case. [Effects of the Invention]

[0021] According to the present invention, operational errors that may occur due to the existence of multiple sales modes can be avoided. [Brief explanation of the drawings]

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view showing the external configuration of a product sales data processing device (hereinafter referred to as a "full-self-service POS device") 1-1 according to a first embodiment of the present invention, and Fig. 2 is a block diagram showing the configuration of the full-self-service POS device 1-1.

[0024] The self-service POS device 1-1 is a POS device in which customers themselves register the products they wish to purchase and pay for them. As shown in FIG. 1, it is configured with a touch panel 11 installed on top of a base 10, a scanner unit 13 for reading product barcodes (product identification information) and a printer unit 15 installed below the touch panel 11, a bill slot 17 installed at the top of the front of the base 10, a coin slot 18 installed diagonally below the bill slot 17, and a change outlet 19 installed below the bill slot 17. This self-service POS device 1-1 does not have a scale (mass detection means) that detects the mass of a registered product and compares it with a reference mass for that product, but of course a separate scale could be installed. Furthermore, although not shown, an input assistance means such as an integrated or connectable numeric keypad could also be installed.

[0025] 2, the full-self-service POS device 1-1 includes a CPU 201, a ROM 203, a RAM 205, a scanner unit 13, a touch panel 11, a printer unit 15, a communication unit 207, a buzzer 209, a cash deposit / withdrawal unit 211, an imaging unit 212, and a sensor unit 213, which are interconnected by a bus 213. As mentioned above, if a scale or input assistance means is installed separately, the scale (mass detection means) or input assistance means is connected to this bus 213.

[0026] The CPU 201 controls the operation of the full-self-service POS device 1-1 by reading and executing programs stored in the ROM 203. The ROM 203 stores programs (including a program that causes the CPU 201 to execute the process shown in FIG. 5 below). The RAM 205 stores various information, such as the contents of the product file 40 shown in FIG. 4 below, history information, etc.

[0027] The scanner unit 13 is an input means that optically reads barcodes (product codes, product identification information) attached to products. The touch panel 11 has the functions of a display unit 111 that displays various information to customers and an input unit 113 that inputs various commands by touching the screen. The input unit 113 is also an input means. In this example, the printing unit 15 prints on receipts and issues printed receipts from the issuing port 151. The communication unit 207 communicates with other devices via the LAN 33, which will be described below. The buzzer 209 emits a buzzer sound when it is necessary for the store clerk to confirm an operation.

[0028] The deposit / withdrawal unit 211 is configured to include a change dispenser, a credit card reader, an electronic money reader, etc., and their respective control units, and is used to perform payment processing using cash, credit, and electronic money. The deposit / withdrawal unit 211 executes a payment using cash using the change dispenser, and outputs the result of the payment (for example, information indicating whether the payment has been successful) to the CPU 201 via the bus 213. The change dispenser includes a banknote slot 17 for inserting and ejecting banknotes, a coin slot 18 for inserting coins, and a change outlet 19 for ejecting change. The deposit / withdrawal unit 211 also executes a payment using credit, and outputs the result of the payment to the CPU 201. The deposit / withdrawal unit 211 also executes a payment using electronic money, and outputs the result of the payment to the CPU 201.

[0029] The imaging unit 212 is used to photograph the deposit unit, that is, the customer himself, for example, to photograph and store the customer's payment operation. Normally, the image is stored as evidence in case of trouble with money transfer, but it can also be used to photograph and store the image of customers who frequently perform fraudulent operations or operational errors, and process the image into divisible data.

[0030] The sensor unit 213 is a human presence sensor that detects that a customer is approaching the device, and is used to return or transition the operation screen from a sleep state or an advertising video to the initial product registration screen, or to announce operation guidance messages such as "Welcome" and "Please register your product" by voice or image.

[0031] 3 is a block diagram showing an example of the configuration of a merchandise sales data processing system (hereinafter referred to as "POS system") 30 configured using a plurality of the above-described full-self-service POS devices 1-1. As shown in the figure, the POS system 30 is configured by connecting a management device (store controller) 31 and a plurality of full-self-service POS devices 1-1 to each other via a LAN 33, either wired or wirelessly.

[0032] 3 is just one example, and for example, together with the full-self-service POS device 1-1, a face-to-face self-service POS device (face-to-face semi-self-service POS device) 1-2 (where the clerk and customer meet face-to-face, with the clerk registering products and the customer performing deposit and settlement operations), a conventional normal POS device (where product registration and deposit and settlement operations are generally performed by the clerk), a semi-self-service POS system in which the registration device and settlement machine are separate (where the clerk registers products and the customer performs deposit and settlement operations), a self-service settlement machine, etc. It is also possible to configure one of the POS devices to have the functions of the management device 31, and omit the management device 31.

[0033] The management device 31 is a computer that controls the POS system 30, and acquires and manages various information such as the below-described product files (product master) 40 (40-1, 40-2) from external devices (not shown, for example, a headquarters server or a removable storage medium) via the network 35. The management device 31 transmits the latest product files 40 to the full-self-service POS device 1-1 as needed.

[0034] FIG. 4(a) is a diagram showing an example of a product file 40-1. As shown in the figure, the product file 40-1 includes information such as product identification information (product code such as a JAN code), product name (product name, item name), and sales price for each product, as well as information on other sales modes. Here, other sales modes refer to different sales modes for the same product. Specifically, as shown in FIG. 4(a), for example, the same canned beer "XXX" may be sold as a "single item," as a "6-can pack," or as a "case of 12 cans." In other words, the sales mode in this example indicates the sales unit of the product. However, the sales mode referred to in the present invention does not only refer to the sales unit, but also includes various other modes, such as different designs (e.g., championship commemorative designs) for the same number of cans, or different modes for regular products and products with bonuses. As shown in Figure 4(a), when other sales modes are "present," all of the product identification information of other sales modes related to this product identification information is linked. Specifically, in Figure 4(a), the "single" can of beer "XXX" is linked to the product identification information "XXX" of another sales mode, "6-can pack," which is a "single" and the product identification information "XXXX" of a "case of 12 cans." The "6-can pack" can of beer "XXX" is linked to the product identification information "XXX" of another sales mode, "single" and the product identification information "XXXX" of a "case of 12 cans." The "12-can case" can of beer "XXX" is linked to the product identification information "XXX" of another sales mode, "single" and the product identification information "XXX△" of a "6-can pack." That is, product file 40-1 associates the price for each sales mode of each product sold with product identification information assigned to each sales mode of the product, and is stored in storage means such as RAM 205 or a hard disk (not shown). Figure 4(b) is a diagram showing an example of other product file 40-2. As shown in the figure, product file 40-2 includes information such as each product's PLU code, product name, specifications, sales unit, and product identification information (sales JAN code), as well as information on other sales modes such as a single item JAN code. Whether or not other sales modes exist can be determined by the presence of a single item JAN code in addition to the sales JAN.The price of each product sold for each sales mode can be found by reading the price stored in the store database linked to the PLU code. That is, in the case of product file 40-2, the price of each product sold for each sales mode is associated with the product identification information assigned to each sales mode of the product, and is stored in storage means such as RAM 205 or a hard disk (not shown).

[0035] Next, the operation of the full-self-service POS device 1-1 will be described. Figure 5 is an operational flow diagram showing an example of the operation process of the full-self-service POS device 1-1. A customer approaches the full-self-service POS device 1-1 with one or more products they wish to purchase, and holds the barcode (product identification information) of one of the products over the scanner unit 13 to input the barcode information into the scanner unit 13 (step ST1-1). In this example, it is assumed that the input product barcode is the barcode for a single can of beer "XXX".

[0036] Next, the product file 40 is searched for the input product to determine whether the product has multiple sales modes (step ST1-2). In this example, since there are multiple sales modes, the process proceeds to step ST1-3 ("Y" in step ST1-2). If the product does not have multiple sales modes, there is no risk of selecting the wrong sales mode, so the process proceeds directly to step ST1-7 without performing steps ST1-3 to ST1-6 described below, and the product is registered ("N" in step ST1-2).

[0037] Next, in step ST1-3, which is reached from step ST1-2, it is determined whether or not a scale (mass detection means) is connected to this full-self-service POS device 1-1.In this example, since a scale is not installed, the process proceeds to step ST1-4 ("N" in step ST1-3).

[0038] Next, in step ST1-4, it is determined whether the sales mode of the input product is the most expensive among the related sales modes. In this example, the most expensive among the related sales modes is the sales mode of a case containing 12 cans, not a single item sales mode, so the process proceeds to step ST1-5 ("N" in step ST1-4), and multiple sales modes are output on the touch panel 11 and displayed for selection.

[0039] 6A, 6B, and 6C are diagrams showing examples of display screens G1, G1-2, and G1-3 that display multiple selectable sales modes. These display screens G1, G1-2, and G1-3 are used to confirm whether the sales mode of the product associated with the input barcode is correct. As shown in FIG. 6A, the screen displays "This is a single can of beer 'XXX'. Is that correct?" Alternatively, as shown in FIGS. 6B and 6C, the screen displays "Are you sure you want to purchase this single item?" This allows the customer to recognize (confirm) that the product has multiple sales modes. If the selection is correct, the customer presses the "Yes" button G11. On the other hand, if the sales mode of the product being purchased is incorrect, the customer presses the "6 cans" button G12 or the "12 cans" button G13, which indicates the correct sales mode. By performing this operation, the customer completes the correction process without having to re-enter the correct product or scan the barcode. In other words, if the scanned product has multiple sales modes, the customer can confirm whether the sales mode is correct, and if it is incorrect, select another sales mode (product selection). This effectively prevents operational errors before they occur. Furthermore, as shown in Figures 6B and 6C, the sales mode may be displayed together with a picture or image. Customers can easily make a selection by comparing the picture or image with the actual product. Also, as shown in Figure 6C, a button G14 for inputting the quantity may be displayed so that the quantity can be registered directly. Furthermore, the button G14 for inputting the quantity may be a mechanical key such as a numeric keypad equipped on the device, and a message such as "To enter the quantity, please press the number key" may be displayed.

[0040] FIG. 7 shows an example of another display screen G2, G3 that displays multiple selectable sales modes. These display screens G2, G3 also function as a confirmation means for confirming whether the sales mode of the product associated with the input barcode is correct. As shown in the figure, by displaying "This is a single can of beer "XXX." Is this correct?", the customer is made aware (confirms) that multiple sales modes are available for this product. If the selection is correct, the customer presses the "Yes" button G21. On the other hand, if the sales mode of the product to be purchased is incorrect, the customer presses the "No" button G22. When the "No" button G22 is pressed, another display screen G3 is displayed, displaying a message such as "Please scan the correct barcode" (a re-registration instruction), allowing the customer to select another sales mode. This effectively prevents operational errors. In these display screens G2, G3, the sales mode may also be displayed together with an image or picture.

[0041] In this example, the touch panel 11 is configured to display a screen that allows selection of multiple sales modes, but selection may instead be made by inputting numbers using a numeric keypad, etc. Furthermore, multiple sales modes may be notified by audio display, buzzer, rotating light, display on the receipt, communication output to another device, etc.

[0042] As described above, if multiple sales modes are displayed as selectable in step ST1-5, the fact that a product with multiple sales modes has been entered (scanned) is notified to other devices (step ST1-6), regardless of whether the selection is correct or incorrect. Here, other devices include, for example, a surveillance monitor, another manned POS device, a terminal at a service counter, an attendant terminal, a sign light on the device itself, or an official announcement. The notification is made, for example, by displaying the serial number of the full-self-service POS device 1-1 that entered the product with multiple sales modes. In the case of a sign light, the notification is made in a manner that only the store clerk can understand (such as a color, lighting, or flashing). Furthermore, if the device has an operation display unit on both the customer side and the store clerk side, the notification may be made to the store clerk. The store clerk may then make the correct selection. Furthermore, depending on the customer's rank, for example, for general customers or customers who frequently make operational errors (presumably frequently committing fraud), the notification may be made only to the store clerk.

[0043] Thus, if information on multiple sales modes is output in step ST1-5, a notification to that effect is sent to other devices in step ST1-6. This allows a person other than the person operating the self-service POS device 1-1 (such as a store clerk) to be informed and alerted that there are other sales modes for the product associated with the product identification information input by the scanner unit (input means) 13 (allowing them to keep an eye on the self-service POS device 1-1). Even if the transaction is completed after correcting the error, the operation history remains. In the case of fraud, the wrong product was selected intentionally, so evidence of this remains in the history. The imaging unit (imaging camera) 212, which normally captures the cash deposit / withdrawal unit (change dispenser), may be reoriented to capture the operator, or the entire customer, not just the customer's hands, may be captured. The operation history (operation log) at that time is recorded. If the customer is a registered member, a record is kept for each member. If the operation error is a second time, the notification method may be changed, for example, a comment may be displayed indicating that the same operation error was made the previous time. This makes it easy to prevent mistakes in selecting the sales mode (scanning errors) and fraud, and to secure evidence, allowing for a quick response to these. Furthermore, when a member is recognized or a non-member fraudulent operator is recognized through imaging processing, the device may be configured to issue a notification on its own or to an external party. It also becomes possible to share information with chain or group stores.

[0044] Next, the scanned products or products corrected to the correct sales mode in step ST1-5 are registered (step ST1-7). Next, if registration of all products to be purchased has not been completed ("N" in step ST1-8), the process returns to step ST1-1 and the operation of reading the barcode of the next product is repeated. On the other hand, if registration of all products to be purchased has been completed ("Y" in step ST1-8), information to be used for settling the registered products corresponding to each transaction (settlement information) is generated and stored, and settlement processing is performed using the deposit / withdrawal unit 211 or the like (step ST1-9). The settlement information includes settlement information identification information for identifying the settlement information, the registration date and time, product identification information of each registered product, the product name, sales price, discount information, the transaction number indicating the number of products to be purchased (purchase number), and the total amount (total price) of the products to be purchased. The settlement information may further include registration device identification information for identifying the self-service POS device 1-1 that generated the settlement information (i.e., the self-service POS device 1-1 that registered the product related to the settlement information). The settlement process is a process for paying and settling the price of the registered product selectively using cash, electronic money, a credit card, a debit card, etc. Once the settlement is complete, a receipt is issued using the printing unit 15 or the like (step ST1-10). Alternatively, an electronic receipt may be output instead of a physical receipt.

[0045] In step ST1-4, if the entered sales mode of the product is the sales mode with the highest price among the related sales modes ("Y" in step ST1-4), the multiple sales modes are not displayed (step ST1-5), and the process proceeds to step ST1-6. After notifying other devices, the process proceeds to step ST1-7 to register the product. That is, by skipping step ST1-5, the output of information on the multiple sales modes is restricted. This is for the following reason. That is, if the sales mode with the highest price is selected, the store can easily determine that this is not an illegal selection, and the customer can easily notice if they made a mistake because the price will be higher. For this reason, restricting the output simplifies the operation. Note that in the above example, the output of information on the multiple sales modes is restricted. Instead, the display of the selectable multiple sales modes may be restricted (regardless of whether the output itself is restricted). In either case, the process proceeds to product registration without displaying the multiple sales modes on the touch panel 11, which has the same effect.

[0046] As mentioned above, even if the sales mode of the product entered in step ST1-4 is the highest price sales mode, notification is still sent to other devices in step ST1-6. This is to quickly follow up on simple operational errors. For customers who have registered as members, it is preferable to change the notification mode from the second time onwards, as described above.

[0047] If, in step ST1-3, the full-self-service POS device 1-1 is connected to a scale (mass detection means) for weighing and verifying the entered product, the product can be weighed after the barcode is entered to verify whether it is the correct product. Therefore, steps ST1-4 and ST1-5 are unnecessary because there is no risk of registering the product with an incorrect sales format (although, of course, these steps may be executed just to be safe). Therefore, if, in step ST1-3, a scale (mass detection means) is connected ("Y" in step ST1-3), the mass of the product is detected (step ST1-11). At this time, all products may be scanned and input of the number may be prohibited, or if not prohibited, the quantity may be calculated based on the unit mass. The mass is then compared with the product mass (reference mass) pre-stored in the product file 40 (step ST1-12). If the mass is correct, proceed to step ST1-7 to register the product. If the mass is incorrect, return to step ST1-1 and start again by inputting the correct barcode.

[0048] If a scale error is detected, the system may be configured to automatically or by a store clerk's operation switch to the operation process for when the scale is not connected (the process that moves from step ST1-3 to step ST1-4).Even if there is no scale error, the system may be configured to be able to switch to the operation process for when the scale is not connected by a store clerk's operation.

[0049] As described above, the full-self-service POS device 1-1 is equipped with an output means (such as the CPU 201 that outputs the information to the touch panel 11 in step ST1-5) that outputs information on the sales modes when there are multiple sales modes for a product related to the barcode information (product identification information) input by the scanner unit (input means) 13. This makes it possible to prompt the user to check whether or not they have selected the wrong sales mode for a product with multiple sales modes, thereby preventing such operational errors. It also makes it easier to detect and check potentially fraudulent operations.

[0050] More specifically, when there are multiple sales modes for a product related to the barcode information (product identification information) input by the scanner unit (input means) 13, the touch panel (display means) 11 is provided to display the multiple sales modes in a selectable manner, so that the operator can easily be informed that there are multiple sales modes, and can easily change the sales mode if it is incorrect.

[0051] Furthermore, as described above, the full-self-service POS device 1-1 includes a determination means (such as the CPU 201 that executes step ST1-3) that determines whether a scale (mass detection means) is connected, and if the determination means determines that the scale is connected, the output means (such as the CPU 201 that outputs information on multiple sales modes to the touch panel 11 in step ST1-5) limits (does not output, etc.) the output of the sales mode information. Note that, instead of limiting (doing not output, etc.) the output of sales mode information by the output means as described above, control may be performed to limit (do not display, etc.) the display of selectable multiple sales modes by the display means.

[0052] In this way, when the weight of the product is detected by a scale, the detection can prevent the selection of the sales mode by mistake, so the output operation by the output means (or the display by the display means) can be omitted. In other words, the fully self-service POS device 1-1 can perform optimal processing depending on whether or not a scale is connected.

[0053] Although the program executed by the self-service POS device 1-1 according to the above embodiment is provided in advance in a ROM 203 or the like, the present invention is not limited to this. The program may be provided by being recorded in an installable or executable file 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). The program executed by the self-service POS device 1-1 according to the above embodiment may be stored on a computer connected to a network such as the Internet and downloaded via the network. The program executed by the self-service POS device 1-1 according to the above embodiment may be provided or distributed via a network. This also applies to the following embodiments.

[0054] FIG. 8 is a perspective view showing the external configuration of a product sales data processing device (hereinafter referred to as "face-to-face self-service POS device") 1-2 according to a second embodiment of the present invention, with FIG. 8(a) being a view from the checkout operation surface side, and FIG. 8(b) being a view from the registration operation surface side. FIG. 9 is a block diagram showing the configuration of the face-to-face self-service POS device 1-2. In these figures, parts that are the same as or equivalent to those of the full-self-service POS device 1-1 according to the embodiment shown in FIGS. 1 and 2 are given the same numbers (however, the symbol "-2" is added to each number). Note that matters other than those described below are the same as those in the embodiment shown in FIGS. 1 to 7.

[0055] The face-to-face self-service POS device (face-to-face semi-self-service POS device) 1-2 is a POS device where a store clerk and a customer meet face-to-face, with the clerk registering the items they wish to purchase and the customer paying for the items. It differs from the full-self-service POS device 1-1 shown in FIG. 1 in that, in addition to the checkout side (customer side) touch panel 11-2A, a registration side (clerk side) touch panel 11-2B is installed facing the registration side. In addition to the checkout side scanner unit 13-2A, a registration side (clerk side) scanner unit 13-2B is installed facing the registration side. The printing unit 15-2 can be rotated 180 degrees outward relative to the housing, and in the figure, the issuing port 151-2 faces the registration side. While the printing unit 15-2 is shared by both the registration side and the clerk side, separate printing units may be installed. The orientation change is not limited to a rotating or fixed type, and may be manual or automatic.

[0056] Preset keys used for registering products are provided on the side of the touch panel 11-2B on the registration side. As shown in FIG. 9, this touch panel 11-2B also has a display unit 111-2B that displays various information to the store clerk and an input unit 113-2B that inputs various commands by touching the screen. As shown in FIG. 8, the scanner unit 13-2B uses a handheld wand scanner that optically reads barcodes and the like attached to products. The entire printing unit 15-2 can be rotated 180° relative to the base 10-2, so that its printing port 151-2 can be faced toward either the registration side or the checkout side.

[0057] FIG. 10 is a block diagram showing an example of the configuration of a product sales data processing system (hereinafter referred to as the "POS system") 30-2 configured using multiple counter-operated self-service POS devices 1-2. As shown in the figure, the POS system 30-2 is configured by interconnecting a management device (store controller) 31-2 and multiple counter-operated self-service POS devices 1-2 via a LAN 33-2, either wired or wirelessly. Note that the configuration of the POS system 30-2 shown in FIG. 10 is merely an example. For example, the counter-operated self-service POS device 1-2 may be connected to the full-self-service POS device 1-1, a conventional normal POS device, a semi-self-service POS system with a separate registration device and payment machine, or a self-service payment machine. It is also possible to omit the management device 31-2 by configuring one of the POS devices to have the functions of the management device 31-2.

[0058] This face-to-face self-service POS device 1-2 also performs the same operational processing as shown in Fig. 5. However, in the case of the face-to-face self-service POS device 1-2, the registration processing is performed by a store clerk and the payment processing is performed by the customer facing the device, so in the operational flow shown in Fig. 5, steps ST1-1 to ST1-8 related to registration and steps ST1-11 and ST1-12 are performed by the store clerk, and steps ST1-9 and ST1-10 related to payment processing are performed by the customer.

[0059] In the case of this face-to-face self-service POS device 1-2, the product is registered by a store clerk, so operational errors are less likely to occur than when the product is registered by a customer. However, if the scanned product has multiple sales types, there is still a risk of scanning the wrong barcode. This invention is effective in preventing this and operational errors.

[0060] The face-to-face self-service POS device 1-2 shown in FIG. 8 can be used in a variety of ways, including as a full-self-service POS device, a self-checkout machine, or a registration device for a semi-self-service POS system in which the registration device and checkout machine are separate. This allows for instant switching between modes depending on the store's needs, which helps alleviate staff shortages and speed up checkouts. Switching between modes is achieved, for example, by pressing a mode switch button displayed on the touch panel 11-2B on the registration side. While operating as a face-to-face self-service POS device, the registration data can be sent to or transferred to another device if the other device is capable of receiving the registration data. The store clerk can freely decide whether to have the customer pay in person or at another device, as needed. For example, if there is a long line at the register, customers using credit or electronic money can operate the machine face-to-face, while customers using cash can hand it over to another device, or if it looks like it will take a while to prepare the card or cash, they can hand it over to another device, or elderly people can do it face-to-face and young people can hand it over to another device, etc. When used as a self-checkout machine, it can execute the checkout process by receiving registered data, and when used as a full self-checkout POS device, it can be configured to switch to a self-checkout machine if there is a wait, and if another customer is operating it, it will switch back to a self-checkout machine after that operation is completed.

[0061] When the counter-self-service POS device 1-2 is switched to a full-self-service POS device, the clerk-side touch panel 11-2B and scanner unit 13-2B are not used in the counter-self-service POS device 1-2 shown in FIG. 8. The orientation of the printing unit 15-2 shown in FIG. 8 is inverted toward the customer, with its issuing port 151-2 facing the customer. This results in a mechanical configuration similar to that of the full-self-service POS device 1-1 shown in FIG. 1, and the device can be used as a full-self-service POS device by using the same operational process (operation flow) as the full-self-service POS device 1-1. An example of a POS system is the POS system 30 shown in FIG. 3. When used as a full-self-service POS device, the clerk-side touch panel 11-2B may be configured to display the same screen as the customer-side touch panel 11-2A. This allows the clerk to immediately understand what the customer is doing and, if the customer is having trouble, to provide operating instructions, or to operate the device using the clerk-side touch panel 11-2B.

[0062] FIG. 11 is a block diagram showing an example of the configuration of a product sales data processing system (hereinafter referred to as the "POS system") 30-3 configured using multiple self-checkout machines 1-3, each of which uses the above-mentioned counter-operated self-checkout POS devices 1-2. As shown in the figure, the POS system 30-3 is configured by interconnecting a management device (store controller) 31-3, a registration device (a standard POS device or a counter-operated self-checkout POS device 1-2 is used as the registration device) 50-3, and multiple self-checkout machines 1-3 via a LAN 33-3, either wired or wirelessly. The configuration of the POS system 30-3 shown in FIG. 11 is merely an example; for example, the full-self-checkout POS device 1-1, the counter-operated self-checkout POS device 1-2, or a conventional checkout machine may be connected to the self-checkout machine 1-3. It is also possible to omit the management device 31-3 by configuring one of the POS devices to have the functions of the management device 31-3.

[0063] When the counter-side self-service POS device 1-2 is switched to the self-service checkout machine 1-3, the touch panel 11-2B and scanner unit 13-2B on the registration side are not used, just as when it is switched to the full-self-service POS device. The printing unit 15-2 shown in FIG. 8 is also turned over to face the customer, with its issuing port 151-2 facing the customer. Meanwhile, product registration is performed by the registration device 50-3, and the self-service checkout machine 1-3 receives the accounting data for the products registered by the registration device 50-3. This allows the device to be used as the self-service checkout machine 1-3.

[0064] The registration device 50-3 is a conventional normal POS device (or a POS device that switches over to the above-mentioned face-to-face self-service POS device 1-2 and uses it as this registration device) where a store clerk registers products, and executes a product registration process to register products to be purchased. Through this product registration operation, product identification information is input to the registration device 50-3, and product information corresponding to the input product identification information is acquired. The registration device 50-3 also generates and stores information (payment information) used to settle the registered products for each transaction. Even when a store clerk registers a product using this typical POS device, registration device 50-3, if the clerk accidentally scans the product identification information (e.g., barcode) attached to a single can of beer instead of the product identification information attached to the wrapper of a six-pack of canned beer, the customer's display screen may display a different version of the product's volume and specifications (e.g., a different color, flashing, etc.) to alert the customer, and the clerk's registration screen may display a pop-up message such as "This is a single 350ml bottle of XXX beer." Along with this notification message, a key may be provided to change the registered product to the correct product with one touch. Alternatively, a last-minute correction button may be displayed, which can be pressed to rescan the correct product identification information. When displaying a list of registered products for subtotaling, the corresponding product display column may be displayed differently from the others, or a mark may be displayed. A mark may also be added to the receipt. In addition, for items registered by mistake, the history is managed by adding them to the history of normal correction processing or by using a separate flag. Specifically, flag 1: normal correction, flag 2: sales mode change correction, or the flags may be managed in a separate area.

[0065] In this embodiment, multiple self-checkout machines 1-3 are installed, and one of the multiple machines executes the checkout process using the checkout information generated by the registration device 50-3. The following first and second designation modes can be used to specify the self-checkout machine 1-3 that should execute the checkout process from among the multiple self-checkout machines 1-3.

[0066] In the first designation mode, a store clerk uses the registration device 50-3 to designate the self-checkout machine 1-3 that will execute the payment process. That is, the store clerk designates the self-checkout machine 1-3 that will execute the payment process from among multiple self-checkout machines 1-3 by performing an operation to designate the self-checkout machine 1-3 on the registration device 50-3. The registration device 50-3 may be configured to display operation information indicating the operating status of each self-checkout machine 1-3, so that the operation status of each self-checkout machine 1-3 can be confirmed on the registration device 50-3 when the store clerk designates the self-checkout machine 1-3.

[0067] When a store clerk designates a self-checkout machine 1-3, settlement information including the product registration data generated in the registration device 50-3 is transmitted to the designated self-checkout machine 1-3 via LAN 33-3. That is, when a self-checkout machine 1-3 is designated following a product registration process, the registration device 50-3 transmits settlement information including the product registration data based on the product registration process to the designated self-checkout machine 1-3. Note that, in this embodiment, the registration device 50-3 transmits settlement information directly to the self-checkout machine 1-3, but it may also transmit the settlement information to the self-checkout machine 1-3 via the management device 31-3.

[0068] In the second specification mode, a payment medium (a receipt (registered trademark)) is issued from the registration device 50-3, and the customer has one self-checkout machine 1-3 read the receipt handed to them by the store clerk. That is, the customer specifies the self-checkout machine 1-3 to execute the payment process from among the multiple self-checkout machines 1-3 by having the self-checkout machine 1-3 read the receipt handed to them by the store clerk. The receipt has registration device identification information indicating the registration device 50-3 that issued it and payment information printed on it in the form of either a barcode (one-dimensional code) or a two-dimensional code. When the self-checkout machine 1-3 reads the code on the receipt, it obtains product registration data from the payment information indicated by the read code.

[0069] The self-checkout machine 1-3 executes the checkout process in response to the customer's operation. When the checkout process is completed, the self-checkout machine 1-3 notifies the registration device 50-3 of the completion of the checkout process.

[0070] In this embodiment, the self-checkout machine 1-3 to be used for settlement can be selected from multiple self-checkout machines 1-3 in two ways: a store clerk selects the self-checkout machine 1-3 to be used for settlement using the registration device 50-3 (first selection method); and a customer has the registration device 50-3 issue a receipt to be handed to the customer, and the customer has one self-checkout machine 1-3 read the receipt handed to them by the store clerk (second selection method). However, the selection of a self-checkout machine 1-3 is not limited to the above. For example, the self-checkout machine 1-3 may be selected as follows:

[0071] In one embodiment, in response to an operation performed on a send button displayed on the touch panel (clerk display unit) of the registration device 50-3 upon completion of product registration (or an operation that declares completion of product registration), the registration device 50-3, for example, inquires about the status of the self-checkout machines 1-3 to identify self-checkout machines 1-3 that are capable of processing the payment (for example, that are not experiencing a failure and are not in use), and then selects one self-checkout machine 1-3 from among the self-checkout machines 1-3 that are not in use according to a predetermined rule (for example, in order of the checkout machine number).The registration device 50-3 then transmits payment information to the selected self-checkout machine 1-3 and instructs it to perform the payment process.

[0072] In another embodiment, the priority of the payment process for the self-checkout machines 1-3 is set in advance. Then, upon completion of product registration, the touch panel (clerk display) of the registration device 50-3 displays a message indicating that a send button, which instructs the sending of payment information to the self-checkout machine 1-3, is enabled. In response to the send button being pressed, the registration device 50-3 checks whether the self-checkout machines 1-3 are capable of payment processing in order according to the set priority, and if it is not confirmed that payment processing is possible, it checks the self-checkout machine 1-3 with the next highest priority. Then, the registration device 50-3 sends payment information to the self-checkout machine 1-3 that was first confirmed to be capable of payment processing and instructs it to perform payment processing.

[0073] In another embodiment, the registration device 50-3 transmits settlement information to all self-checkout machines 1-3. When a self-checkout machine 1-3 that has received the settlement information becomes capable of executing the settlement process using the settlement information it has received, it transmits a settlement process execution notification to the registration device 50-3 that sent the settlement information, informing it that it will execute the settlement process. In response to receiving the settlement process execution notification, the registration device 50-3 displays a display (a settlement process execution display) indicating the self-checkout machine 1-3 to which the settlement process execution notification was sent. The store clerk simply looks at the settlement process execution display and tells the customer which self-checkout machine 1-3 will execute the settlement process. At this time, along with the display indicating that the settlement process is being executed, a sign pole (not shown) installed on the self-service settlement machine 1-3 that sent the settlement process execution notification may be lit in a predetermined pattern, or a predetermined alarm sound may be output from the buzzer of the self-service settlement machine 1-3 (corresponding to buzzer 209-2 in Figure 9) to notify the user that the settlement process will be executed.

[0074] In another embodiment, a store clerk moves a shopping cart containing products that have been registered by the registration device 50-3 to one of the basket locations provided for each self-checkout machine 1-3. The basket locations are equipped with a sensor that detects the placed shopping cart. When the sensor determines that a shopping cart has been placed in the basket location, the corresponding self-checkout machine 1-3 makes a request to obtain the corresponding payment information from the registration device 50-3 and then executes the payment process. In this case, the self-checkout machine 1-3 that is to execute the payment process may also notify the user that it will execute the payment process by, for example, lighting up a signpost or emitting an alarm.

[0075] In another aspect, the registration device 50-3 transmits to one self-checkout machine 1-3 settlement instruction information including settlement information and transfer order information that sets the transfer order among multiple self-checkout machines 1-3. The transfer order information may specify the transfer order cyclically among the self-checkout machines 1-3. If the self-checkout machine 1-3 that received the settlement instruction information is capable of executing the settlement process, it sends a settlement process execution notification to the registration device 50-3 that sent the settlement instruction information, and executes the settlement process using the settlement information included in the received settlement instruction information. On the other hand, if the self-checkout machine 1-3 that received the settlement instruction information is unable to execute the settlement process, it forwards the received settlement instruction information to the next self-checkout machine 1-3 in the transfer order in accordance with the transfer order information included in the received settlement instruction information. In this way, by sequentially transferring the settlement instruction information among the self-checkout machines 1-3, a procedure equivalent to specifying the self-checkout machine 1-3 that should execute the settlement process is realized.

[0076] Although the present invention has been described above as an embodiment, it is not limited to the above embodiment and various modifications are possible within the scope of the claims and the technical concept described in the specification and drawings. Furthermore, any configuration not directly described in the specification and drawings is within the scope of the technical concept of the present invention as long as it achieves the functions and effects of the present invention.
