Description

  An embodiment of the present invention relates to a checkout system, a settlement apparatus included in the system, and a control program for causing a computer to function as a settlement apparatus.

  As a checkout system for mass retailers, there is a type in which a registration device for registering a product to be traded in the transaction for each transaction and a settlement device for processing settlement of the transaction based on data of the registered product are separated. .

  The registration device generally comprises a scanner, which generates registration data of a product scanned (registered). Then, the registration device transfers the generated registration data to the settlement device. The payment device generally comprises an input device for payment data pertaining to cash transactions, credit transactions and the like. The settlement apparatus then processes the settlement of the transaction with the payment data input via the input device based on the registration data. In a checkout system consisting of such a registration device and a settlement device, a shop clerk operates a registration device and a two-person system in which the registration device and the settlement device are operated by different clerks, and a shopper operates the settlement device. There is a sharing system, so-called semi-self system.

  In the case of the semi-self method, if the shopper takes time to operate the settlement apparatus, the subsequent shopper will wait for settlement. In order to avoid such a situation, a plurality of payment devices are usually connected to one registration device. Then, the registration device that has finished registration of the commodity to be traded in the transaction is to transfer the registration data to any available settlement device.

  By the way, after the registration data has been transferred from the registration apparatus to the settlement apparatus, the shopper may purchase additional goods or cancel the purchase of the goods. In such a case, conventionally, the registration data transferred to the settlement apparatus is called back to the registration apparatus. Then, after adding the data of the product to be additionally purchased to the registration data or deleting the data of the product for which the purchase is canceled from the registration data in the registration device, the registration data is again transmitted to any settlement device . Therefore, in the registration device, an operation for recalling the registration data and an operation for retransmitting the recalled registration data to the settlement device are required.

  Hereinafter, an embodiment of a checkout system capable of additional purchase of a product or cancellation of purchase of a product without recalling registration data transferred to the settlement apparatus to the registration apparatus will be described with reference to the drawings. In the present embodiment, a semi-self checkout system is exemplified, which is built in a store such as a mass sales store, and a store clerk operates a registration apparatus and a shopper operates a settlement apparatus.

First Embodiment
FIG. 1 is a perspective view of a checkout system 10 in the present embodiment. The checkout system 10 includes at least one registration device 11 and at least one payment device 12. In FIG. 1, a checkout system 10 is shown which includes two registration devices 11 and four payment devices 12. The number of registration devices 11 and settlement devices 12 included in the checkout system 10 is arbitrary, and the ratio of the number of registration devices 11 to the number of settlement devices 12 is also arbitrary. The registration device 11 and the settlement device 12 are installed at a checkout corner of a store such as a supermarket.

  The registration device 11 has a role called a checker, and the store clerk 21 of the above store is the operator. In the settlement apparatus 12, a shopper 22 who purchases a product to be sold at the above store becomes the operator. However, the settlement apparatus 12 may be operated by the store clerk 21.

  The registration device 11 is attached to the work table 23 in FIG. The work table 23 has a rectangular top. A plurality of work tables 23 are arranged so that the longitudinal directions of the top plates are substantially parallel to each other, thereby forming a passage (checkout lane) for the shopper 22.

  The registration device 11 has functions of registration of a purchased product, generation of registration data and transfer of registration data to the settlement device 12, and settlement processing. The registration is to register a product purchased by the shopper 22 in the registration device 11 as a purchased product. For example, by scanning a barcode attached to a product with a scanner, the product is registered in the registration device 11 as a purchased product. The registration data is data relating to purchased goods registered as one transaction. The registered data includes a product code, which is an identification code of a purchased product, a product name, a unit price, a quantity, an amount of money, and the like. The settlement process is to process settlement of a transaction which is a commodity buying and selling act on the basis of registration data. For payment, cash, a credit card, electronic money, etc. are used as the payment.

  The settlement device 12 has a settlement processing function. That is, when the registration data is transferred from the registration device 11, the settlement apparatus 12 processes transaction settlement based on the registration data.

  FIG. 2 is a block diagram showing the main circuit configuration of the registration device 11 and the settlement device 12. The registration device 11 and the settlement device 12 are both connected to a LAN (local area network) 13 which is a network. Although not shown, a server is connected to the LAN 13. The server has a product database in which product information such as product name and unit price is set in association with the product code of each product.

  The registration device 11 and the settlement device 12 exchange information via the LAN 13. The network may use another communication network such as the Internet or a wireless LAN instead of the LAN 13. Further, information may be exchanged between the registration device 11 and the payment device 12 via the server.

  The registration device 11 includes a CPU (central processing unit) 11a, a ROM (read-only memory) 11b, a RAM (random-access memory) 11c, an auxiliary storage unit 11d, a drawer opening unit 11e, a scanner 11f, and two touch panels 11g1 and 11g2. , A printer 11h, a card reader / writer 11i, a communication unit 11j, and a transmission system 11k.

The CPU 11a is connected to the ROM 11b, the RAM 11c, and the auxiliary storage unit 11d via the transmission system 11k to configure a computer.
The CPU 11a corresponds to the central part of the computer. The CPU 11a controls each unit to realize various functions as the registration device 11 based on the operating system, the middleware, and the application program stored in the ROM 11b and the RAM 11c.

  The ROM 11 b corresponds to the main storage portion of the computer. The ROM 11 b stores the operating system. The ROM 11 b may store the above middleware or application program. The ROM 11 b may store data to be referred to when the CPU 11 a performs various processes.

  The RAM 11 c corresponds to the main storage portion of the computer. The RAM 11 c stores data to be referred to when the CPU 11 a performs various processes. The RAM 11 c is also used as a so-called work area in which data temporarily used when the CPU 11 a performs various processes is stored.

  The auxiliary storage unit 11d corresponds to an auxiliary storage portion of the computer. The auxiliary storage unit 11d stores data used when the CPU 11a performs various processes, or data generated by the process of the CPU 11a. For example, an EEPROM (electric erasable programmable read-only memory), an HDD (hard disk drive), an SSD (solid state drive), or the like can be used as the auxiliary storage unit 11 d.

  The application program stored in the ROM 11 b or the auxiliary storage unit 11 d includes a control program described regarding the information processing executed by the registration device 11. Transfer of the registration device 11 is generally performed in a state where the control program is stored in the ROM 11 b or the auxiliary storage unit 11 d. However, the registration device 11 may be transferred in a state where the control program is not stored in the ROM 11 b or the auxiliary storage unit 11 d. In this case, the control program is transferred to a removable recording medium such as a magnetic disk, a magneto-optical disk, an optical disk, a semiconductor memory or the like. Alternatively, the control program may be transferred via the network, and the control program may be written to the auxiliary storage unit 11 d of the registration device 11 separately transferred.

The drawer opening unit 11e automatically opens the drawer for storing money.
The scanner 11 f reads the barcode attached to the product to obtain the product code of the product. Various known types of scanners can be used as the scanner 11 f as they are. The scanner 11 f may correspond to only one of various known types, or may correspond to a plurality of types. That is, the scanner 11 f may include a fixed or handy two-dimensional code scanner. The scanner 11 f may also include a scanner of a type that identifies an item from an image of the item using image recognition technology.

  Of the two touch panels 11g1 and 11g2, one touch panel 11g1 is for the store clerk, and the other touch panel 11g2 is for the customer. The touch panels 11g1 and 11g2 each include a display device and a touch sensor. The display device sets the display screen as an arbitrary screen such as a GUI screen. As a display device, for example, a known device such as a color LCD can be used. The touch sensor is disposed so as to overlap the display surface of the display device. The touch sensor detects the touch position of the operator on the display surface of the display device, and sends the position information to the CPU 11a. A well-known device can be used as a touch sensor.

  The touch panel 11g1 for the store clerk is provided on the work table 23 so that the display screen faces the work space side of the store clerk 21. The touch panel 11g2 for customers is provided on the work table 23 so that the display screen faces the aisle side for the shopper 22.

  The printer 11 h issues a receipt by printing various character strings or images on receipt paper. For example, a thermal printer or a dot impact printer can be used as this type of printer 11 h.

  The card reader / writer 11i has a function of reading data recorded in a card and a function of writing data in the card. The card may include a payment card such as a credit card, a debit card, an electronic money card, a prepaid card, etc., as well as a membership card called a members' card or a point card. The card reader / writer 11i reads and rewrites data (such as balance) of electronic money stored in the electronic money card. The card reader / writer 11i may be any device of magnetic type, contact type or non-contact type, and may include a plurality of types of devices.

  The communication unit 11 j performs data communication with a plurality of payment devices 12 connected via the LAN 13. The communication unit 11 j can also perform data communication with another registration device 11 via the LAN 13.

  The transmission system 11k transmits data transferred between the CPU 11a, the ROM 11b, the RAM 11c, the auxiliary storage unit 11d, the drawer opening unit 11e, the scanner 11f, the touch panels 11g1 and 11g2, the printer 11h, the card reader / writer 11i and the communication unit 11j. . As the transmission system 11k, known ones can be used including various buses such as a system bus and various interface circuits connecting the buses and the respective units.

  As hardware of such a registration device 11, it is possible to use, for example, an existing POS terminal.

  The settlement apparatus 12 includes a CPU 12a, a ROM 12b, a RAM 12c, an auxiliary storage unit 12d, an automatic change machine 12e, a scanner 12f, a touch panel 12g, a printer 12h, a card reader / writer 12i, a communication unit 12j and a transmission system 12k.

  The automatic change machine 12e receives coins and bills to be inserted. The automatic change machine 12e also discharges coins and bills as change.

  The other functions of the CPU 12a, the ROM 12b, the RAM 12c, the auxiliary storage unit 12d, the scanner 12f, the touch panel 12g, the printer 12h, the card reader / writer 12i, the communication unit 12j and the transmission system 12k are the CPU 11a, the ROM 11b, the RAM 11c and the auxiliary storage of the registration device 11. It is equivalent to the unit 11d, the touch panels 11g1 and 11g2, the printer 11h, the card reader / writer 11i, the communication unit 11j, and the transmission system 11k.

  That is, the CPU 12a is connected to the ROM 11b, the RAM 11c, and the auxiliary storage unit 11d via the transmission system 11k to configure a computer. Then, the CPU 12a controls each unit to realize various operations as the settlement apparatus 12 based on the operating system, the middleware, and the application program stored in the ROM 12b and the RAM 12c.

  The application program stored in the ROM 12 b or the auxiliary storage unit 12 d includes a control program described regarding the information processing executed by the settlement apparatus 12. Transfer of the settlement apparatus 12 is generally performed in a state where the control program is stored in the ROM 12 b or the auxiliary storage unit 12 d. However, the settlement apparatus 12 may be transferred in a state where the control program is not stored in the ROM 12 b or the auxiliary storage unit 12 d. In this case, the control program is transferred to a removable recording medium such as a magnetic disk, a magneto-optical disk, an optical disk, a semiconductor memory or the like. Alternatively, the control program may be transferred via the network, and the control program may be written to the auxiliary storage unit 12 d of the separately transferred settlement device 12 described above.

  As hardware of such a settlement apparatus 12, it is possible to use, for example, a POS terminal compatible with the existing self system.

  The checkout system 10 including the registration device 11 and the settlement device 12 configured as described above forms the data memory areas 31 and 32 shown in FIG. 3 in the registration devices 11 and the RAMs 11 c and 12 c of the settlement device 12 respectively.

  The data memory area 31 is an area for storing registration data for one transaction. The registration data is a collection of records including items of item code, item name, unit price, quantity, and amount. The product code is a unique code for identifying each product individually. For example, a product code represented by a barcode is attached to each product, and the registration device 11 can obtain the product code by scanning the barcode with the scanner 11 f. The item name and unit price are the item name and the price per point of the item identified by the corresponding item code. The number is the registered number of the same product, and the amount is the amount for the registered number. Hereinafter, the data memory area 31 is referred to as transaction memory. Then, the one of the registration device 11 is represented by the transaction memory 31a, and the one of the settlement device 12 is represented by the transaction memory 31b.

  The data memory area 32 is an area for storing the total number and the total amount. The total number is the sum of the number of items included in the registration data. The total amount is the sum of the amount of goods included in the registration data. Hereinafter, the data memory area 32 is referred to as a total memory. Then, the one of the registration device 11 is represented by the total memory 32a, and the one of the settlement device 12 is represented by the total memory 32b.

  The checkout system 10 also forms data memory areas 41 and 42 shown in FIG. 4 in the RAM 11 c of the registration device 11.

  The data memory area 41 is an area for temporarily storing the product code, the product name, the unit price, the number, and the amount of one registered product. The data memory area 41 is hereinafter referred to as a temporary buffer 41.

  The data memory area 42 stores counters C1, C2, C3 and C4 in association with the codes "1", "2", "3" and "4" which individually identify each settlement device 12. The data memory area 42 is hereinafter referred to as a counter table 42.

  FIGS. 5 to 8 are flowcharts showing main procedures of information processing executed by the CPU 11a of the registration device 11 according to the control program. FIG. 9 is a flow chart showing a main procedure of information processing executed by the CPU 12a of the settlement apparatus 12 according to the control program. FIGS. 10 to 14 are schematic views showing various screen examples displayed on the touch panels 11g1 and 11g2 of the registration device 11, respectively. FIGS. 15 to 18 are schematic views showing various screen examples displayed on the touch panel 12 g of the settlement apparatus 12. Hereinafter, the operation of the checkout system 10 will be described using these figures. The contents of the processes described below are merely examples, and various processes that can obtain similar results can be appropriately used.

First, the operation of the registration device 11 will be described.
The registration device 11 has a registration mode as one of the operation modes. When the registration device 11 is activated in this registration mode, the CPU 11a starts control processing of the procedure shown in the flowchart of FIG. First, the CPU 11a initializes the RAM 11c (Act 1). By this initialization, the transaction memory 31a, the total memory 32a and the temporary buffer 41 are cleared. Also, the counters C1 to C4 associated with the respective codes "1" to "4" of the counter table 42 are reset to "0".

  Next, the CPU 11a causes the registration screen SC1 (see FIG. 10) to be displayed on a part of the screen of the touch panel 11g (Act 2).

  The registration screen SC1 displays the contents of the temporary buffer 41, the transaction memory 31a, and the total memory 32a, and causes the store clerk 21 to confirm the implementation status of the registration process. An example of the registration screen SC1 is shown in FIG. The registration screen SC1 includes display areas R1 and R2. The display area R1 includes a display field r11 in which the product name and unit price of the most recently registered product for purchase are displayed, a display field r12 in which the number is displayed, a display field r13 in which the amount is displayed, and 1 transaction A display field r14 is formed on which the total number and the total amount of each product registered for purchase are displayed. In the display area R2, a list of product names, numbers, unit prices and amounts of products for which purchase registration has been made prior to the products shown in the display area R1 is formed.

  Although not shown, the CPU 11a also displays various function buttons such as a commodity button and a subtotal button for the store clerk 21 to designate a commodity out of the area on the touch panel 11g, which is the registration screen SC1. Let

  If the store clerk 21 confirms that the registration screen SC1 is displayed on the touch panel 11g, it recognizes that the registration of the product purchased by the shopper 22 is possible. Then, when the shopper 22 brings the purchased product and comes to the work table 23, the clerk 21 operates the scanner 11f or the product button, for example, to sequentially input the product code of the purchased product. Then, after inputting the product codes of all the purchased products, the clerk 21 touches the subtotal button. By the above-described operation, registration of a product purchased by one shopper (registration of purchase on one transaction) is completed.

  In response to such a registration operation, the CPU 11a of the registration device 11 executes the following information processing. First, the CPU 11a that has displayed the registration screen SC1 waits for an input of a product code (Act 3). When a product code is input via the scanner 11f or the product button (YES in Act 3), the CPU 11a acquires product information such as a product name, a unit price, etc., which is set in the product database in association with the product code. . Further, the CPU 11a multiplies this unit price by the number to calculate the amount of money for the number. The number is a numerical value when it is substituted by a ten key or the like before the product code is input, and is “1” when it is not substituted. Thus, the CPU 11a generates commodity sales data including the commodity code, the commodity name, the unit price, the number and the amount, and stores the commodity sales data in the temporary buffer 41 (Act 4). At this time, when the commodity sales data is already stored in the temporary buffer 41, the CPU 11a moves the commodity sales data to the transaction memory 31 as one record.

  The CPU 11a adds the number and the amount stored in the temporary buffer 41 to the total memory 32a. Then, the CPU 11a updates the registration screen SC1 so that the contents of the temporary buffer 41 and the total memory 32a are displayed in the display area R1 and the contents of the transaction memory 31a are displayed in the display area R2 (Act 5).

  After updating the registration screen SC1, the CPU 11a checks whether the next product code has been input (Act 6). If the product code is not input (NO in Act 6), the CPU 11a checks whether the subtotal button is touched (Act 7). If the subtotal button is not touched (NO in Act 7), the CPU 11a checks again if the product code is input (Act 6). Thus, the CPU 11a waits for the commodity code to be input or the subtotal button to be touched as Act 6 and Act 7. When the CPU 11a confirms the occurrence of another event such as another operation being performed in the standby state, the CPU 11a shifts to processing according to the occurrence event. Such an operation is the same in other standby states.

  In the standby state of Act 6 and Act 7, when the product code is input (YES in Act 6), the CPU 11a proceeds to the process of Act 4. Then, the CPU 11a repeats the subsequent processing in the same manner as described above.

  If the subtotal button is touched in the standby state of Act 6 and Act 7 (YES in Act 7), the CPU 11a executes the processing of Act 8 and Act 9. The processing procedure of Act 8 and Act 9 is not limited to this order. The order may be reversed.

  In Act 8, the CPU 11 a moves the commodity sales data stored in the temporary buffer 41 to the transaction memory 31 as one record. And CPU11a produces | generates registration data based on the content of transaction memory 31a. In Act 9, the CPU 11a causes the transfer destination selection screen SC2 (see FIG. 11) to be displayed on a part of the screen of the touch panel 11g.

  An example of the transfer destination selection screen SC2 is shown in FIG. The transfer destination selection screen SC2 includes display areas R3, R4, R5, R6, R7, R8 and buttons B1, B2, B3, B4, B5, B6, B7.

  The display area R3 displays the total number of the total memory 32a, the total amount of money, and the like. The display area R4 displays various messages. Buttons B1 and B2 are a subtotal discount button B1 and a subtotal discount button B2 for the store clerk 21 to designate that the discount or discount is applied to the total amount. The button B3 is a return button B3 for the store clerk 21 to designate that a partial area of the screen of the touch panel 11g be returned to the registration screen SC1.

  The display areas R <b> 5 to R <b> 8 indicate whether or not transfer of registration data to each of the four settlement devices 12 is possible. Buttons B4 to B7 are transfer buttons B4 to B7 for the store clerk 21 to designate transfer of registration data to each of the four settlement apparatuses 12. The settlement apparatus 12 does not receive transfer of registration data during execution of the settlement process. In the display areas R5 to R8 associated with the settlement apparatus 12 in such a state, "transfer impossible" is displayed. Conversely, "transferable" is displayed in the display areas R5 to R8 associated with the settlement apparatus 12 that has received the transfer of registration data. The transfer buttons B4 to B7 may be hidden when the associated settlement apparatus 12 does not receive the transfer of the registration data. Further, instead of hiding the transfer buttons B4 to B7, the display mode may be changed depending on whether the associated settlement apparatus 12 receives the transfer of the registration data.

  Having displayed the transfer destination selection screen SC2, the CPU 11a confirms whether or not the settlement apparatus 12 as the transfer destination of the registration data is designated (Act 10). When the settlement apparatus 12 is not designated (NO in Act 10), the CPU 11a confirms whether or not the return button B3 is input (Act 11). If the return button B3 is not input (NO in Act 11), the CPU 11a checks again whether or not the settlement apparatus 12 is designated (Act 10). Thus, the CPU 11a waits for the settlement device 12 to be designated or the return button B3 to be input as Act 10 and Act 11.

  In the standby state of Act10 and Act11, when confirming that the return button B3 is input (YES in Act11), the CPU 11a returns a partial area of the screen of the touch panel 11g to the registration screen SC1 (Act12). Thereafter, the CPU 11a proceeds to the process of Act 6 and repeats the subsequent processes in the same manner as described above.

  The clerk 21 who has confirmed the transfer destination selection screen SC2 determines the settlement apparatus 12 to which the registration data is to be transferred. Then, the store clerk 21 touches the transfer buttons B4 to B7 for the settlement apparatus 12 decided as the transfer destination. At this time, the store clerk 21 determines the transfer destination of the registration data from the transferable payment devices 12. If there is no transferable payment apparatus 12, the clerk 21 determines the payment apparatus 12 which seems to be the earliest available, and sets it as the transfer destination of registration data.

  When any of the transfer buttons B4 to B7 is touched in Act10 and Act11 standby states (YES in Act 10), the CPU 11a selects a settlement device corresponding to the touched transfer button (hereinafter referred to as the settlement device 12x) Is designated as the transfer destination of registration data. Then, the CPU 11a executes each process of Act 13, Act 14, and Act 15. The processing procedures of Act 13, Act 14, and Act 15 are not limited to this order. The order may be reversed.

In Act 13, the CPU 11a transfers registration data to the settlement apparatus 12x (Act 13). Specifically, the CPU 11a instructs the communication unit 11j to transmit the registration data to the LAN 13 with the communication address set in the settlement apparatus 12x as the transmission destination address and the communication address set in itself as the transmission source address. Do. In response to this instruction, the communication unit 11 j transmits registration data in which the transmission destination address and the transmission source address are set to the LAN 13. This registration data is received by the settlement apparatus 12x whose transmission destination address matches the communication address.
Here, the CPU 11a cooperates with the communication unit 11j to constitute transfer means for transferring registration data to any one of the settlement apparatuses 12.

  In Act 14, the CPU 11a counts up the counter (hereinafter referred to as counter Cx) associated with the code of the settlement apparatus 12x in the counter table 42 by "1" (Act 14). In Act 15, the CPU 11a causes the notification screen SC3 (see FIG. 12) to be displayed on a part of the screen of the touch panel 11g (Act 15).

  An example of the notification screen SC3 is shown in FIG. The notification screen SC3 includes a display area R9 and buttons B8, B9, and B10.

  The display area R9 displays the total number of the total memory 32a and the total amount and also displays a message indicating the settlement apparatus 12x to which the registration data is transferred. The button B8 is a close button B8 for instructing the store clerk 21 to close the notification screen SC3. The button B9 is an addition button B9 for the store clerk 21 instructing the additional purchase of a product. The button B10 is a cancel button B10 for the store clerk 21 instructing the cancellation of the purchase of a product.

  The store clerk 21 who has confirmed the notification screen SC3 notifies the shopper 22 that, among the payment devices 12, the payment device 12x displayed in the display area R9 should perform the payment. The shopper 22 receiving this notification moves to the designated settlement device 12x and performs an operation for settlement.

  By the way, at the stage of transferring registration data to the settlement apparatus 12x, the shopper 22 may offer additional purchases of goods. Alternatively, the shopper 22 may receive an offer to cancel the purchase of a product. If such an offer is not received, the store clerk 21 touches the close button B9. In the case of receiving an offer for additional purchase, the store clerk 21 touches the add button B10. If the sales clerk 21 receives a request to cancel the purchase, the salesperson 21 touches the cancel button B11.

  Having displayed the notification screen SC3, the CPU 11a checks whether the close button B8 has been touched (Act 16). If the close button B8 is not touched (NO in Act 16), the CPU 11a checks whether the add button B9 is touched (Act 17). When the addition button B9 is not touched (NO in Act 17), the CPU 11a confirms whether the cancel button B10 is touched (Act 18). When the cancel button B10 is not touched (NO in Act 18), the CPU 11a confirms whether the close button B8 is touched again (Act 16). Thus, the CPU 11a waits for Act 16 to Act 18 to be touched by the close button B8, the additional button B9, or the cancel button B10.

  When the close button B8 is touched in the standby state of Act 16 to Act 18 (YES in Act 16), the CPU 11a erases the notification screen SC3 and ends the information processing according to the control program. Thereafter, the CPU 11a again starts the information processing of the procedure shown in the flowchart of FIG. 5 to prepare for the purchase registration of the product purchased by the next shopper.

  In the standby state of Act 16 to Act 18, when the addition button B9 is touched (YES in Act 17), the CPU 11a executes the information processing of the procedure shown in the flowchart of FIG. That is, the CPU 11a displays the additional screen SC4 (see FIG. 13) on a part of the screen of the touch panel 11g (Act 21).

  An example of the addition screen SC4 is shown in FIG. The addition screen SC4 includes a display area R10. The display area R10 has a display field r101 in which the product name and unit price of the product to be additionally registered are displayed, a display field r102 in which the number of products to be additionally registered is displayed, and the number of products to be additionally registered. A display field r103 in which the amount of money is displayed is formed.

  Having displayed the addition screen SC4, the CPU 11a waits for input of the product code of the product to be additionally registered (Act 22). When a product code is input via the scanner 11f or the product button (YES in Act 22), the CPU 11a is a product such as a product name or unit price set in the product database in association with the product code as described above. Get information. Further, the CPU 11a multiplies this unit price by the number to calculate the amount of money for the number. The number is a numerical value when it is substituted by a ten key or the like before the product code is input, and is “1” when it is not substituted. The CPU 11a generates additional update data including a product code, a product name, a unit price, a quantity and an amount, and stores the additional update data in the temporary buffer 41 (Act 23). Then, the CPU 11a updates the addition screen SC4 so that the product name, the unit price, the number and the price of the additional update data stored in the temporary buffer 41 are displayed on the addition screen SC4 (Act 24).

  After updating the additional screen SC4, the CPU 11a waits for the subtotal button to be touched (Act 25). If the subtotal button is touched (YES in Act 25), the CPU 11a executes the processes of Act 26 and Act 27. The processing procedure of Act 26 and Act 27 is not limited to this order. The order may be reversed.

  In Act 26, the CPU 11a transfers the additional update data stored in the temporary buffer 41 to the settlement apparatus 12x designated as the transfer destination of the registration data in the process of Act 10. Specifically, the CPU 11a uses the communication address set in the settlement apparatus 12x as a transmission destination address, and uses the communication address set in itself as a transmission source address to transmit additional update data to the LAN 13 to the communication unit 11j. To command. In response to this instruction, the communication unit 11 j transmits, on the LAN 13, additional update data in which the transmission destination address and the transmission source address are set. The additional update data is received by the settlement apparatus 12x whose transmission destination address matches the communication address.

In Act 27, the CPU 11a causes the notification screen SC3 to be displayed again on part of the screen of the touch panel 11g.
When the processes of Act 26 and Act 27 end, the CPU 11a proceeds to the process of Act 16 and repeats the subsequent processes in the same manner as described above.

  When the cancel button B10 is touched in the standby state of Act 16 to Act 18 (YES in Act 18), the CPU 11a executes the process of the procedure shown in the flowchart of FIG. That is, the CPU 11a causes the cancellation screen SC5 (see FIG. 14) to be displayed on a part of the screen of the touch panel 11g (Act 31).

  An example of the cancellation screen SC5 is shown in FIG. The cancel screen SC5 includes a display area R11. In the display area R11, a display field r111 in which the product name and unit price of the product for which the purchase is canceled is displayed, a display field r112 in which the number of products for which the purchase is canceled is displayed, A display field r113 in which the amount of money is displayed is formed.

  Having displayed the cancel screen SC5, the CPU 11a waits for the input of the product code of the product for which the purchase is to be canceled (Act 32). When the incoming product code is input through the scanner 11f or the product button (YES in Act 32), the CPU 11a associates the product code with the product name and the product name, unit price, etc., as described above. Get product information. Further, the CPU 11a multiplies this unit price by the number to calculate the amount of money for the number. The number is a numerical value when it is substituted by a ten key or the like before the product code is input, and is “1” when it is not substituted. The CPU 11a attaches a minus sign to the number and sets it as the cancellation number. In addition, the CPU 11a attaches a minus sign to the amount of money and sets it as a cancellation amount of money. The CPU 11a generates cancellation update data including the commodity code, the commodity name, the unit price, the number of cancellations, and the cancellation amount, and stores the cancellation update data in the temporary buffer 41 (Act 33). Then, the CPU 11a updates the cancellation screen SC5 such that the product name, the unit price, the number of cancellations, and the cancellation amount of the cancellation update data stored in the temporary buffer 41 are displayed on the cancellation screen SC5 (Act 34).

  After updating the cancel screen SC5, the CPU 11a waits for the subtotal button to be touched (Act 35). If the subtotal button is touched (YES in Act 35), the CPU 11a executes the processes of Act 36 and Act 37. The processing procedure of Act 36 and Act 37 is not limited to this order. The order may be reversed.

  In Act 36, the CPU 11a transfers the cancellation update data stored in the temporary buffer 41 to the settlement apparatus 12x designated as the transfer destination of the registration data in the process of Act 10. Specifically, the CPU 11a sets the communication address set in the settlement apparatus 12x as a transmission destination address, sets the communication address set in itself as a transmission source address, and transmits cancellation update data to the LAN 13 to the communication unit 11j. To command. In response to this instruction, the communication unit 11 j transmits cancellation update data in which the transmission destination address and the transmission source address are set to the LAN 13. The cancellation update data is received by the settlement apparatus 12x whose transmission destination address matches the communication address.

In Act 37, the CPU 11a causes the notification screen SC3 to be displayed again on part of the screen of the touch panel 11g.
When the processes of Act 36 and Act 37 end, the CPU 11a proceeds to the process of Act 16 and repeats the subsequent processes in the same manner as described above.

  Here, the CPU 11a causes the touch panel 11g to display the notification screen SC3 to transfer the registration data to the settlement apparatus 12x and thereafter wait for the update waiting means to wait for the input of the update data until the next transaction is started. Configure.

  Further, the CPU 11a cooperates with the touch panel 11g and the communication unit 11j to constitute a transmitting means for transmitting the update data to the registration data transferred to the settlement apparatus 12x to the settlement apparatus 12x to which the registration data is transferred. Specifically, the transmitting means transmits the update data input in a standby state for the input of the update data to the settlement apparatus 12x which has transferred the registration data immediately before.

Next, the operation of the settlement apparatus 12 will be described.
When the settlement apparatus 12 is activated, the CPU 12a starts information processing of the procedure shown in the flowchart of FIG. First, the CPU 12a sets the screen of the touch panel 12g as a standby screen (Act 51). The standby screen indicates that there is no situation in which payment processing is performed, and any information may be displayed. For example, it is assumed that the standby screen displays a message indicating that payment processing can not be performed, or displays an arbitrary image representing an advertisement or the like as a screen saver. After setting the screen of the touch panel 12g as a standby screen, the CPU 12a waits for reception of registration data (Act 52).

  As described above, the CPU 11a of the registration device 11 transmits registration data from the communication unit 11j to the LAN 13 in the process of Act 13 of FIG. The registration data is received by the communication unit 12j provided in the settlement apparatus 12 as the destination. The settlement apparatus 12 which has received the registration data can specify the registration apparatus 11 which is the transmission source of the registration data by storing the transmission source address of the registration data.

  When the registration data is received (YES in Act 52), the CPU 12a develops the registration data in the transaction memory 31b (Act 53). That is, the CPU 12a extracts the record of the product code, the product name, the unit price, the number and the amount from the registered data, and stores the record in the transaction memory 31b. Further, the CPU 12a adds up the points and the amount of the records stored in the transaction memory 31b, and stores the total number and the total amount in the total memory 32b.

  Here, the CPU 12a cooperates with the RAM 12c to configure storage means for storing the registration data transferred from the registration device 11 in the storage unit (transaction memory 31b).

Next, the CPU 12a causes the payment method selection screen SC6 (see FIG. 15) to be displayed on a part of the screen of the touch panel 12g (Act 54).
An example of the payment method selection screen SC6 is shown in FIG. Payment method selection screen SC6 includes display areas R12 and R13 and buttons B11 and B12. The display area R12 displays operation guidance for the shopper 22 who operates the settlement apparatus 12. The display area R13 displays the total number and the total amount stored in the total memory 32b. The button B11 is a payment method button B11 for the shopper to designate one of a plurality of payment methods. The button B12 is a store clerk call button B13 for the shopper 22 to designate calling of the store clerk 21.

  Although cash, a credit card, and electronic money are illustrated as a payment method in this embodiment, a payment method is not limited to these. Other payment methods may be added. Also, any payment method may be omitted.

  The shopper 22 who has confirmed the payment method selection screen SC6 determines the payment method of the price, and touches the payment method button. However, if there is a product to be additionally purchased or if there is a commodity to be canceled, the shopper offers to the clerk before touching the payment method button. Then, after waiting for the registration device 11 to register the cancellation of the product that is desired to be additionally registered or to be canceled, the payment method button is touched.

  Having displayed the payment method selection screen SC6, the CPU 12a checks whether the payment method button B11 has been touched (Act 55). If the payment method button B11 is not touched (NO in Act 55), the CPU 12a confirms whether additional update data or cancellation update data has been received (Act 56). When the additional update data or the cancellation update data is not received (NO in Act 56), the CPU 12a checks again whether the payment method button B11 is touched (Act 55). Thus, the CPU 12a waits for the payment method button B11 to be touched or to receive additional update data or cancellation update data as Act 55 and Act 56.

  Here, the CPU 12a cooperates with the touch panel 12g to configure a transaction start instruction based on registration data stored in the storage unit (transaction memory 31b), that is, start standby means for waiting for a touch input of the payment method button B11. Do.

  In the standby state of Act 55 and Act 56, when the additional update data or the cancellation update data is received (YES in Act 56), the CPU 12a updates the registration data developed in the transaction memory 31b (Act 57). That is, when the additional update data is received, the CPU 12a adds the product code, the product name, the unit price, the number, and the amount included in the additional update data to the transaction memory 31b as one record. However, if a record including the same product code is already stored in the transaction memory 31b, the CPU 12a adds the number and the amount included in the additional update data to the number and the amount of the record, and adds the record Not performed. When the cancellation update data is received, the CPU 12a searches the transaction memory 31b for a record including the same product code. Then, the CPU 12a subtracts the number and the amount included in the cancellation update data from the number and the amount of the record. As a result, when the number and the amount of money become "0", the CPU 12a deletes this record from the transaction memory 31b.

  When the registration data expanded in the transaction memory 31 is updated by the additional update data or the cancellation update data, the CPU 12a recalculates the total number and the total amount by the data of the transaction memory 31. Then, the CPU 12a updates the data of the total memory 32b and, as shown in FIG. 16, also updates the total score and the total amount displayed in the display area R13 of the payment method selection screen SC6 (Act 58). Thereafter, the CPU 12a proceeds to the process of Act 55, and repeats the subsequent processes in the same manner as described above.

  FIG. 16 shows the payment method selection screen when the update data in the transaction memory 31b is updated by additional registration data relating to one commodity of 500 yen while the payment method selection screen SC6 shown in FIG. 15 is displayed. The SC6 is illustrated.

  The CPU 12a updates the registered data stored in the storage unit (transaction memory 31b) when the updated data is received from the registration device 11 in cooperation with the RAM 12c and the communication unit 12j in the waiting state of the settlement start instruction. To configure updating means for updating.

  When the payment method button B11 is touched in the standby state of Act 55 and Act 56 (YES in Act 55), the CPU 12a pays the payment method selected by the payment method button B11 to a part of the screen of the touch panel 12g. The screen SC7 (see FIG. 17) is displayed (Act 58).

  An example of the payment screen SC7 is shown in FIG. FIG. 17 is a payment screen SC7 when cash is selected as the payment method. Payment screen SC7 includes display areas R13 and R14 and a button B13. The display area R13 displays operation guidance for the shopper 22 who operates the settlement apparatus 12. Display area R14 displays the total amount, the input amount, and the remaining amount. A button B13 is a settlement button B13 for a shopper who has finished inserting cash to specify execution of settlement. The shopper who has selected cash as the payment method inserts cash into the automatic change machine 12e. And if cash more than the total amount is inserted, the settlement button B13 is touched.

  Having displayed the payment screen SC7, the CPU 12a waits for the settlement button B13 to be touched (Act 59). If the settlement button B13 is touched (YES in Act 59), the CPU 12a executes settlement processing according to the selected payment method (Act 60). For example, when cash is selected as the payment method, the CPU 12a executes settlement processing for cash payment. Then, the CPU 12a controls the printer 12h to issue a receipt, and controls the automatic change machine 12e to dispense change. When a credit card is selected, the CPU 12a executes payment processing for credit payment. Then, the CPU 12a controls the printer 12h to issue a credit slip. When electronic money is selected, the CPU 12a executes settlement processing for electronic money payment. Then, the CPU 12a controls the printer 12h to issue a receipt, and controls the card reader / writer 12i to update the balance of the electronic money. Since such payment processing is well known, detailed description is omitted.

  When the settlement process is completed, the CPU 12a displays a completion screen SC8 (see FIG. 18) on a part of the screen of the touch panel 12g (Act 61).

  An example of the completion screen SC8 for cash payment is shown in FIG. The completion screen SC8 includes display areas R15, R16, and R17. The display area R15 displays operation guidance for the shopper 22 who operates the settlement apparatus 12. Display area R16 displays a guidance image. The guidance image is an image for guiding the shopper 22 of the issue opening of the receipt and the payout opening of the change. Therefore, the shopper can easily know from the guide image the place where the receipt is issued and the place where the change is paid out. Display area R16 displays the amount of change. Therefore, the shopper can know the amount of change from the data of the display area R16.

  Having displayed the completion screen SC8, the CPU 12a notifies the registration device 11 of the registration data transmission source of the completion of the transaction (Act 62). Specifically, the CPU 12a uses the transmission source address stored at the time of reception of the registration data as the transmission destination address, and transmits the transaction completion notification command to the LAN 13 using the communication address set therein as the transmission source address. To control the communication unit 12j. As a result, a transaction completion notification command in which the transmission destination address and the transmission source address are set is transmitted via the LAN 13. Then, this command is received by the registration device 11 whose transmission destination address matches the communication address.

  The CPU 11a of the registration device 11 having received the command of the transaction completion notification executes the reception interrupt process of the procedure shown in the flowchart of FIG. That is, the CPU 11a confirms whether the received command is a transaction completion notification (Act 41). If it is a command other than the transaction completion notification (NO in Act 41), the CPU 11a executes a process according to the command.

  If the received command is a transaction completion notification (YES in Act 41), the CPU 11a resets the counter Cx associated with the code identifying the settlement apparatus 12x of the command transmission source in the counter table 42 to "0". To do (Act 42). Above, CPU11a ends reception interruption processing.

  As described above, according to the first embodiment, even when the shopper additionally purchases a product or cancels the purchase of a product after transfer of registration data from the registration device 11 to the settlement device 12 is completed, The registration data transferred to the settlement apparatus 12 can be dealt with without being called back to the registration apparatus 11.

  Therefore, in the registration device 11, the operation for recalling the registration data and the operation for retransmitting the recalled registration data to the settlement device 12 are unnecessary, so that the manipulation can be simplified.

Second Embodiment
In the first embodiment, if it is within a period from when the registration data is transferred from the registration device 11 to the settlement device 12 and until the close button B8 of the notification screen SC3 is operated, the shopper 22 according to the registration data It is possible to purchase or cancel the purchase of a product. Conversely, when the close button B8 of the notification screen SC3 is operated by the store clerk 21, the shopper 22 can not perform additional purchase or purchase cancellation of the product.

  Then, next, after the close button B8 is operated in the registration device 11 and the registration of the product purchased by the next shopper is started, if the payment device 12 is selected before the payment method is selected, additional purchase of the product or A second embodiment which enables cancellation of purchase will be described using the drawings. The drawings common to the first embodiment are incorporated, and the description thereof is omitted. Specifically, FIGS. 1 to 4, 8, 9, and 11 to 18 are used.

  19 to 21 are flowcharts showing the main procedures of information processing executed by the CPU 11a of the registration device 11 according to the control program in the second embodiment, and FIG. 22 is a schematic diagram showing an example of the registration screen SC11. FIG. In these FIGS. 19-22, the same code | symbol is attached | subjected to the part which is common in the corresponding figure (FIG. 5-7, FIG. 10) of 1st Embodiment.

  As shown in FIG. 22, in the second embodiment, an interrupt button B21 is added to the registration screen SC11. The interrupt button B21 closes the notification screen SC3 and starts registration of a product purchased by the next shopper (hereinafter referred to as shopper 22b), and then indicates the shopper in front (hereinafter referred to as shopper 22a). The store clerk 21 touches when an offer for additional purchase or cancellation of purchase is received from the.

  As shown in FIG. 19, the CPU 11a of the registration device 11 waits for the touch of the interrupt button B21 in the standby state of Act 6 and Act 7 (Act 71). Then, when the interrupt button B21 is touched (YES in Act 71), the CPU 11a executes the processes of Act 72, Act 73, and Act 74. Note that the processing procedures of Act 72, Act 73, and Act 74 are not limited to this order. The order may be reversed.

  At Act 72, the CPU 11a sets an interrupt flag. The interrupt flag is, for example, 1-bit data stored in the RAM 11 c. At Act 73, the CPU 11a moves the data of the temporary buffer 41 to the save buffer. The save buffer has the same area structure as the temporary buffer 41, and is formed in the RAM 11c. In Act 74, the CPU 11a causes the interrupt screen SC12 (see FIG. 23) to be displayed on part of the screen of the touch panel 11g.

  An example of the interrupt screen SC12 is shown in FIG. The interrupt screen SC12 includes buttons B22, B23, and B24. The button B22 is a close button B22 for instructing the store clerk 21 to close the interrupt screen SC12. The button B23 is an addition button B23 for the store clerk 21 to instruct an additional purchase of a product. The button B10 is a cancel button B24 for instructing the store clerk 21 to cancel the purchase of a product.

  The clerk 21 who has confirmed the interruption screen SC12 touches the addition button B23 when the offer from the shopper 22a is an additional purchase, and touches the cancel button B11 when the purchase cancellation is made. If the request for additional purchase or purchase cancellation is canceled, the close button B22 is touched.

  Having displayed the interrupt screen SC12, the CPU 11a checks whether the close button B22 has been touched (Act 75). If the close button B22 is not touched (NO in Act 75), the CPU 11a confirms whether the add button B23 is touched (Act 76). If the addition button B23 is not touched (NO in Act 76), the CPU 11a confirms whether the cancel button B24 is touched (Act 77). If the cancel button B24 is not touched (NO in Act 77), the CPU 11a confirms whether the close button B22 is touched again (Act 75). Thus, the CPU 11a waits for the close button B22 to be touched, the additional button B23 to be touched, or the cancel button B24 to be touched as Act 75 to Act 77.

  When the close button B22 is touched in the standby state of Act 75 to Act 77 (YES in Act 75), the CPU 11a executes the processes of Act 78, Act 79, and Act 80. Note that the processing procedures of Act 78, Act 79, and Act 80 are not limited to this order. The order may be reversed.

  In Act 78, the CPU 11a resets the interrupt flag. In Act 79, the CPU 11a restores the data saved in the save buffer in the temporary buffer 41. In Act 80, the CPU 11a erases the interrupt screen SC12, and causes the registration screen SC11 to be displayed again on part of the screen of the touch panel 11g.

  Thus, when the processes of Act 78, Act 79 and Act 80 are completed, the CPU 11a proceeds to the process of Act 6 and repeats the subsequent processes in the same manner as described above.

  When the addition button B23 is touched in the standby state from Act 75 to Act 77 (YES in Act 76), the CPU 11a executes the process of the procedure shown in the flowchart of FIG. This process substantially corresponds to the process described using FIG. 6 in the first embodiment. The difference is the processing after the subtotal button is touched in Act 25.

  That is, if the subtotal button is touched (YES in Act 25), the CPU 11a determines the transfer destination of the additional update data (Act 81). Specifically, the CPU 11a searches the counter table 42 and recognizes the settlement apparatus 12x in which the counter C is increased to "1" as the transfer destination of the additional update data. Then, the CPU 11a transmits the additional update data generated from the data stored in the temporary buffer 41 to the settlement apparatus 12x (Act 82). If the additional update data has been transmitted, the CPU 11a proceeds to the process of Act 78 and repeats the subsequent processes in the same manner as described above.

  When the cancel button B24 is touched in the standby state from Act 75 to Act 77 (YES in Act 77), the CPU 11a executes the process of the procedure shown in the flowchart of FIG. This process substantially corresponds to the process described using FIG. 7 in the first embodiment. The difference is in the processing after the subtotal button is touched in Act 35.

  That is, if the subtotal button is touched (YES in Act 35), the CPU 11a determines the transfer destination of the cancellation update data (Act 83). Specifically, the CPU 11a searches the counter table 42 and recognizes the settlement apparatus 12x whose counter C is incremented to "1" as the transfer destination of the cancellation update data. Then, the CPU 11a transmits cancellation update data generated from the data stored in the temporary buffer 41 to the settlement apparatus 12x (Act 84). If the cancellation update data has been transmitted, the CPU 11a proceeds to the process of Act 78 and repeats the subsequent processes in the same manner as described above.

  On the other hand, the settlement apparatus 12 operates in the same manner as in the first embodiment. That is, in a state where the payment method selection screen SC6 is displayed on part of the screen of the touch panel 12g, when the additional update data or the cancellation update data is received, the CPU 12a executes the processes of Act 57 and Act 58.

  Therefore, according to the second embodiment, even after the registration of the product purchased by the next shopper 22b is started in the registration apparatus 11, before the previous shopper 22a selects the payment method in the settlement apparatus 12 In this case, the shopper 22a can purchase or cancel the purchase of a product. At this time, as in the first embodiment, since the registration data transferred to the settlement apparatus 12 is not called back to the registration apparatus 11, the operation can be simplified as well.

Third Embodiment
In the second embodiment, when the shopper 22a offers to purchase or cancel the purchase of a product, the registration of the product purchased by the shopper 22b is interrupted to cope with the offer. However, it is not always the case that the shopper 22b does not complain if the registration is interrupted.

  Therefore, next, a third embodiment for dealing with additional purchase or cancellation of purchase of a product for the shopper 22a after waiting for registration of a product purchased by the shopper 22b will be described with reference to the drawings. The drawings common to the first and second embodiments are incorporated, and the description thereof is omitted. Specifically, FIGS. 1 to 4, 8, 9, 11 to 18, and 20 to 23 are incorporated.

  FIG. 24 is a flowchart showing main procedures of information processing executed by the CPU 11a of the registration device 11 according to the control program in the third embodiment. In FIG. 24, the same reference numerals as in the corresponding drawings (FIG. 5) of the first embodiment denote the same parts.

  As shown in FIG. 24, after the CPU 11a causes the registration screen SC11 (see FIG. 22) to be displayed on part of the screen of the touch panel 11g in Act 2, the interrupt button B21 is touched in the last purchase registration. Whether or not it is confirmed (Act 91). As described in the second embodiment, when the interrupt button B21 is touched during purchase registration, the CPU 11a sets an interrupt flag. Then, the CPU 11a checks whether the interrupt flag is set.

  If the interrupt flag is not set (NO in Act 91), the CPU 11a proceeds to the process of Act 3. That is, the CPU 11a waits for the input of the product code. When the product code is input via the scanner 11 f or the product button (YES in Act 3), the CPU 11 a generates product sales data and stores it in the temporary buffer 41 (Act 4). The CPU 11a also updates the registration screen SC1 by adding the number and the amount stored in the temporary buffer 41 to the total memory 32a (Act 5).

  After updating the registration screen SC1, the CPU 11a waits for the item code to be input (Act 6) or that the subtotal button is touched (Act 7). Further, the CPU 11a checks whether the interrupt flag is set (Act 92). If the interrupt flag is not set (NO in Act 92), the CPU 11a confirms whether the interrupt button B21 is touched (Act 93). If the interrupt button B21 is not touched (NO in Act 93), the CPU 11a proceeds to the process of Act 6 and repeats the subsequent processes in the same manner as described above. On the other hand, if the interrupt flag is set (YES in Act 92), the CPU 11a proceeds to Act 6 without executing Act 93, and repeats the subsequent processes as described above.

  Therefore, in a state in which the interrupt flag is not set, the CPU 11a waits for input of the product code, touch of the subtotal button, or touch of the interrupt button B21. In the state in which the interrupt flag is set, the CPU 11a waits for the item code to be input or the subtotal button to be touched.

  When the shopper 22b is registering a product to be purchased, if the shopper 22a receives a request for additional purchase or cancellation of purchase of a product, the clerk 21 touches the interrupt button 21. However, registration of the product purchased by the shopper 22b is not interrupted.

  When the interrupt button B21 is touched (YES in Act 93), the CPU 11a executes the processes of Act 94 and Act 95. The processing procedures of Act 94 and Act 95 are not limited to this order. The order may be reversed.

  In Act 94, the CPU 11a sets an interrupt flag. In Act 95, the CPU 11a further counts up the counter Cx whose count value is “1” among the counters in the counter table 42 by “1”.

  When the processes of Act 94 and Act 95 are completed, the CPU 11a proceeds to the process of Act 6 and repeats the subsequent processes in the same manner as described above. Therefore, in this case, since the interrupt flag is set, the CPU 11a waits for the commodity code to be input or the subtotal button to be touched. In this standby state, the operation when the product code is input or when the subtotal button is touched is the same as that of the first or second embodiment.

  On the other hand, if the interrupt flag is set in Act 3 (YES in Act 91), the interrupt button B21 is touched during the registration of the product purchased by the shopper 22b. In this case, the CPU 11a executes the processes of Act 96 and Act 97. The processing procedures of Act 96 and Act 97 are not limited to this order. The order may be reversed.

  In Act 96, the CPU 11a resets the interrupt flag. In Act 97, the CPU 11a causes the interrupt screen SC12 (see FIG. 23) to be displayed on part of the screen of the touch panel 11g.

  The clerk 21 who has confirmed the interruption screen SC12 touches the addition button B23 when the offer from the shopper 22a is an additional purchase, and touches the cancel button B11 when the purchase cancellation is made. If the request for additional purchase or purchase cancellation is canceled, the close button B22 is touched.

  Having displayed the interrupt screen SC12, the CPU 11a checks whether the close button B22 has been touched (Act 98). If the close button B22 is not touched (NO in Act 98), the CPU 11a confirms whether the add button B23 is touched (Act 99). When the addition button B23 is not touched (NO in Act 99), the CPU 11a confirms whether the cancel button B24 is touched (Act 100). If the cancel button B24 is not touched (NO in Act 100), the CPU 11a confirms whether the close button B22 is touched again (Act 98). Thus, the CPU 11a waits for the close button B22 to be touched, the add button B23 to be touched, or the cancel button B24 to be touched as Act 98 to Act 100.

  If the close button B22 is touched in the standby state from Act 98 to Act 100 (YES in Act 98), the CPU 11a proceeds to the processing of Act 2 and repeats the subsequent processing in the same manner as described above. Therefore, in this case, after making a part of the screen of the touch panel 11g into the registration screen SC11 (Act 2), the process waits for the input of the product code (Act 3).

  In the standby state from Act 98 to Act 100, when the addition button B23 is touched (YES in Act 99), the CPU 11a executes the process of the procedure shown in the flowchart of FIG. 20 described in the second embodiment. Then, when the additional update data is transmitted to the settlement apparatus 12x (Act 82), the CPU 11a proceeds to the process of Act 2 and repeats the subsequent processes in the same manner as described above.

  When the cancel button B24 is touched in the standby state from Act 98 to Act 100 (YES in Act 100), the CPU 11a executes the process of the procedure shown in the flowchart of FIG. 21 described in the second embodiment. Then, when the cancellation update data is transmitted to the settlement apparatus 12x (Act 84), the CPU 11a proceeds to the process of Act 2 and repeats the subsequent processes in the same manner as described above.

  On the other hand, the settlement apparatus 12 operates in the same manner as in the first or second embodiment. That is, in a state where the payment method selection screen SC6 is displayed on part of the screen of the touch panel 12g, when the additional update data or the cancellation update data is received, the CPU 12a executes the processes of Act 57 and Act 58.

  Therefore, according to the third embodiment, after the registration of the product purchased by the next shopper 22b is started in the registration device 11, the shopper 22a before that has offered to purchase or cancel the purchase of the product. In this case, it can be dealt with after the shopper 22b has registered the product to be purchased. At this time, as in the first or second embodiment, since the registration data transferred to the settlement apparatus 12 is not called back to the registration apparatus 11, the operation can be simplified as well.

The present invention is not limited to the above embodiment.
For example, in the embodiment described above, the payment method selection screen SC6 is displayed on the settlement apparatus 12 that has received the registration data transferred from the registration apparatus. Then, by waiting for the touch input of the payment method button B11 on the payment method selection screen SC6, the transaction settlement start instruction based on the registration data stored in the storage unit (transaction memory 31b) is waited. When the payment method is one type, the payment method selection screen SC6 is not displayed on the settlement apparatus 12 that has received the registration data. In that case, the settlement device 12 is provided with a declaration button for the shopper to declare the start of payment. For example, in response to the reception of the registration data, the CPU 12a may display a declaration button on a part of the screen of the touch panel 12g. By waiting for the declaration button to be input, the CPU 12a waits for a transaction settlement start instruction based on the registration data stored in the storage unit (transaction memory 31b).

  Further, in the above embodiment, the semi-self type checkout system is illustrated, but the function of the present embodiment can be applied to a two-man checkout system.

  In addition, although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and the gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
