Abstract

To prevent a person who should make settlement from fraudulently leaving without paying a charge.SOLUTION: When receiving a declaration to pay a charge by a first paying means, a settlement device receives the input of payment data by the first paying means. When receiving a declaration to pay the charge by a second paying means, the settlement device receives the input of payment data by the second paying means. Although the settlement device receives an instruction to restore a state of receiving a declaration when receiving a declaration to pay the charge by the first paying device, it does not receive the above-mentioned instruction when receiving a declaration to pay the price by the second paying means. Furthermore, the settlement device restores a state of receiving a declaration of whether the charge is paid by the first paying means or the second paying means when receiving the above-mentioned instruction.SELECTED DRAWING: Figure 14

Description

  An embodiment of the present invention relates to a payment device and a payment program for causing a computer to function as the payment device.

  There is a type of settlement apparatus that processes the payment generated by commerce or service provision, that is, the settlement of the amount that the buyer pays to the seller, which is a type operated by a settler who is not a clerk, such as a shopper or facility user. Further, in this type of payment apparatus, there are a self method in which the settler performs even the registration operation necessary for calculating the payment and a semi-self method in which the registration operation is performed by the clerk.

  In the case where the payment is made in cash in the self- or semi-self type settlement apparatus, the user first selects cash as the payment means. The settler then deposits cash into the cash slot. As a result, when cash more than the price is charged, the settlement is completed. At that time, if a change occurs, the change payment is paid out from the change payment outlet, so the user collects the change.

  By the way, as means for payment of money, it is common to use electronic money, credit card, etc. in addition to cash. For this reason, in the self- or semi-self type settlement apparatus, a first screen for causing the settler to select one of the payment means is displayed on the touch panel. For example, since the button image corresponding to each payment means is displayed on the first screen, the payer touches the button image corresponding to the desired payment means. Then, the screen of the touch panel is switched to a second screen for receiving the input of payment data by the selected payment means.

  Here, it is assumed that there is a settler who wants to change to another payment means although one of the payment means is selected, and the second screen receives an instruction to return to the first screen. "Return" button is displayed. For this reason, after selecting cash as payment means and inserting cash less than the price, operating the "Return" button abuses the fact that cash inserted from the change payment exit is returned, and the settler who leaves without payment is left There is. This type of fraud is similar to the behavior of a settler's act as if the payment is just paid by cash and the change is being collected, so the clerk may miss the fraud.

JP 2017-58744 A

  The problem to be solved by the embodiments of the present invention relates to a settlement apparatus and a settlement program that can prevent the fraud of a settler who is left unpaid.

  In one embodiment, the settlement apparatus comprises a first acceptance means, a second acceptance means, a settlement means, and a return means. The first receiving means receives a declaration to pay the payment by one of the at least two payment means of the first payment means or the second payment means. The second accepting means accepts the input of the payment data by the first payment means when the first acceptance means accepts the declaration to pay the payment by the first payment means. The second accepting means accepts the input of the payment data by the second payment means when the first acceptance means accepts the declaration to pay the payment by the second payment means. The settlement means settles the payment based on the payment data by the first payment means when the second reception means receives the input of the payment data by the first payment means. Further, when the second accepting means accepts the input of the payment data by the second payment means, the settlement means settles the payment based on the payment data by the second payment means. The return means returns to a state of accepting the declaration after the first acceptance means accepts the declaration to pay the payment by the first payment means. Then, after the settlement apparatus receives the declaration to pay the payment by the second payment means by the first reception means, it can not return to the state of receiving the declaration by the return means.

  Hereinafter, an embodiment of a settlement apparatus capable of preventing fraudulentness of a settler who leaves with unpaid money will be described using the drawings. In this embodiment, a settlement apparatus in a semi-self checkout system introduced to a retail store such as a supermarket is exemplified.

First Embodiment
FIG. 1 is a schematic view of a checkout system 10 according to the first embodiment. The checkout system 10 includes a plurality of registration devices 11 and payment devices 12 having a larger number than the registration devices 11. The registration device 11 and the settlement device 12 are arranged for each checkout lane of the store.

  In FIG. 1, two registration devices 11 (11-1, 11-2) and six payment devices 12 (12-1, 12-2, 12-3, 12-4, 12-5, 12- 6) shows the case where two checkout lanes are arranged. In one checkout lane, one registration device 11 (11-1) and three settlement devices 12 (12-1, 12-2, 12-3) are arranged. Then, three settlement devices 12 (12-1, 12-2, 12-3) arranged in the same checkout lane are grouped with respect to the registration device 11 (11-1). Similarly, in the other checkout lane, one registration device 11 (11-2) and three settlement devices 12 (12-4, 12-5, 12-6) are arranged. Then, with respect to the registration device 11 (11-2), three payment devices 12 (12-4, 12-5, 12-6) arranged in the same checkout lane are grouped.

  Note that how many checkout systems 10 each include the registration device 11 and the settlement device 12 is optional. Further, the ratio of the number of registration devices 11 and the number of payment devices 12 arranged in the checkout lane is also arbitrary.

  In the registration device 11, a store clerk 21 who plays a role called a checker is the operator, that is, a so-called registrant. In the settlement apparatus 12, a shopper 22 who purchases a product to be sold in a store becomes the operator, that is, a so-called settlement party. However, the clerk may be a settler.

  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 sales product, generation of accounting data and transfer of accounting data to the settlement device 12, and settlement processing. The registration of the sale item is to register the item purchased by the shopper 22 in the registration device 11 as the sale item. For example, by scanning a barcode attached to a product with a scanner, the product is registered in the registration device 11 as a sales product. The accounting data is data relating to the accounting of sales products registered as one transaction. The accounting data includes a product code, which is an identification code of a sales product, a product name, a unit price, a quantity, an amount, and the like. The settlement process is to settle the price of a transaction which is a commodity buying and selling act based on accounting data. The price is, for example, the total price of the purchased item. If the item purchased is one item, the price of the item can be the price. Also, if there is a discount or discount on the total amount, the price will be the amount after the discount or discount. 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 accounting data is transferred from the registration device 11, the settlement apparatus 12 processes settlement of the transaction price on the basis of the accounting 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 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 middleware or the 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, for example, a registration 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 printer 11 h issues a receipt by printing various character strings or images on a receipt sheet. 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 and an electronic money card, as well as a membership card called a membership card or a point card.

  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 automatic change machine 12e separately provides a coin insertion slot, a coin payout opening, a bill insertion slot, and a bill payout opening. Then, the automatic change machine 12e receives coins and bills inserted from the coin insertion slot and the bill insertion port. Further, the automatic change machine 12e discharges coins and bills as change from the coin payout opening and the bill payout opening.

  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, for example, a settlement program. 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.

By arranging the coin slot 123, the coin dispenser 124, the bill slot 125, and the bill dispenser 126 in a step-like manner as described above, it is possible to look over all the slots from the back side to the near side. it can.

  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. 4 in the RAMs 11 c and 12 c of the registration device 11 and the settlement device 12 respectively.

  The data memory area 31 is an area for storing data of a sale item in one transaction. The data includes items of product code, product 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 the unit price are the name and the price per point of the item identified by the corresponding item code. The number is the number of pieces sold of the same product, and the amount is the amount for the number of pieces sold (sales amount). 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 sales number stored in the transaction memory 31. The total amount is the sum of the sales amounts stored in the transaction memory 31. 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.

  Further, the checkout system 10 forms the data memory area 41 shown in FIG. 5 in the RAM 11 c of the registration device 11 and forms the data memory area 42 in the auxiliary storage unit 11 d 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 sales product. The data memory area 41 is hereinafter referred to as a temporary buffer 41.

  The data memory area 42 stores the settlement device ID and the identification name in association with a series of list numbers (accounting data transfer order) starting from “1”. The settlement device ID is assigned to each settlement device 12 in order to identify each settlement device 12 individually, and is, for example, a unique ID stored in the ROM 12 b. Incidentally, the same registration device ID is stored in the ROM 11 b for each registration device 11. The identification name is a unique name set individually for each settlement device 12. The operator of the registration device 11 can determine which payment device 12 is indicated from the identification name. The data memory area 42 is hereinafter referred to as a list table 42.

  In the list number "1" of the list table 42, the settlement device ID and the identification name of the settlement device 12 installed at the nearest place to the registration device 11 are set in advance, and the list number "2" , The settlement device ID and the identification name of the settlement device 12 installed at the second closest location to the registration device 11 are set in advance. Thus, the transfer order of the accounting data is set in the order of closeness of the distance from the registration device 11. Note that such a setting is an example, and the transfer order may not necessarily be set in the order in which the distances from the registration device 11 are close.

  6 and 7 are flowcharts showing the main procedures of information processing executed by the CPU 11a of the registration device 11 in accordance with the registration program. FIG. 8 is a flow chart showing the main steps of information processing executed by the CPU 12a of the settlement apparatus 12 in accordance with the settlement program. 9 to 11 are flowcharts specifically showing the procedure of the accounting process during the information processing shown by the flowchart of FIG. 12 to 15 are schematic views showing various examples of images displayed on the touch panel 12g 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.

  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.

  Next, the CPU 11a sets the screen of the touch panel 11g as a registration screen (Act 2). The registration screen 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.

  If the store clerk 21 confirms that the registration screen 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 item and comes to the work table 23, the store clerk 21 operates the scanner 11f and the item button, for example, to sequentially enter the item code of the item. Then, when the commodity codes of all the commodities have been input, the clerk 21 touches the subtotal button. By the above operation, registration of a product purchased by one shopper (sales registration of 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 waits for the input of the 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 and a unit price, which is associated with the product code and set in the product database. . 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. After the CPU 11a generates commodity sales data including the commodity code, the commodity name, the unit price, the number and the amount, the CPU 11a stores the commodity sales data in the temporary buffer 41 (Act 4). At this time, if the commodity sales data is already stored in the temporary buffer 41, the CPU 11a moves the stored commodity sales data to the transaction memory 31, and then temporarily stores the new commodity sales data in the temporary buffer 41. Store in

  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 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, the CPU 11a checks whether or not 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. Then, the CPU 11a generates accounting data from the data of the transaction memory 31a and the data of the total memory 32a. In Act 9, the CPU 11a sets the screen of the touch panel 11g as an accounting confirmation screen. The accounting confirmation screen displays the total number, total amount, and the like of the total memory 32a. The accounting confirmation screen displays a button image including a back button and an accounting button. The return button is a button image for the store clerk 21 to specify that the screen of the touch panel 11g be returned to the registration screen. The accounting button is a button image for the store clerk 21 instructing the end of registration of a product for one transaction and transition to accounting.

  The CPU 11a that has displayed the accounting confirmation screen confirms whether or not the accounting button has been input (Act 10). If the accounting button has not been input (NO in Act 10), the CPU 11a checks whether the back button has been input (Act 11). When the back button is not input (NO in Act 11), the CPU 11a checks again whether the accounting button is input (Act 10). Thus, the CPU 11a waits for an accounting button to be input or a back button to be input as Act 10 and Act 11.

  The store clerk 21 who has confirmed the accounting confirmation screen confirms whether or not the registration of the product purchased by the shopper 22 remains. If it remains, the store clerk 21 touches the back button. If not, the store clerk 21 touches the accounting button.

  In the standby state of Act 10 and Act 11, when the return button is input (YES in Act 11), the CPU 11a returns the screen of the touch panel 11g to the registration screen (Act 12). Thereafter, the CPU 11a proceeds to the process of Act 6 and repeats the subsequent processes in the same manner as described above.

  When the accounting button is touched in Act 10 and Act 11 standby states (YES in Act 10), the CPU 11a proceeds to the process of Act 13 of FIG. That is, the CPU 11a reads the list of the ID and the identification name of the settlement apparatus 12 from the list table 42 (Act 13). Next, the CPU 11a detects the settlement device ID of the list number "1" from the list table 42 (Act 14). Then, the CPU 11a instructs the communication unit 11j to transmit the accounting data generated in the process of Act 8 and the list data acquired in the process of Act 13 to the payment apparatus ID of the list number "1" as a destination (Act 15). In response to this instruction, the communication unit 11j transmits “accounting data + list data” having the destination as the payment apparatus ID of the list number “1” and the registration apparatus ID stored in the ROM 11b as the transmission source onto the LAN 13. . The “accounting data + list data” is received by the settlement apparatus 12 whose settlement apparatus ID as the destination matches the settlement apparatus ID stored in the ROM 12 b.

  When the CPU 12a of each settlement device 12 receives "accounting data + list data" via the communication unit 12j, does the settlement device ID added to the data as the transmission destination match the settlement device ID stored in the ROM 12b? Check. If the two do not match, the CPU 12a discards "accounting data + list data". If they match, the CPU 12a takes in "accounting data + list data". Then, the CPU 12a starts the reception interrupt process specifically shown in FIG.

  When the reception interrupt process is started, the CPU 12a first checks the busy flag F (Act 21). The busy flag F is 1-bit data which is set to "1" while the CPU 12a is processing the settlement of the transaction based on the accounting data, and reset to "0" when the processing is completed, and is stored in the RAM 12c There is. Thus, while the busy flag F is set, the settlement device 12 is executing settlement of the transaction. For this reason, the settlement apparatus 12 can not settle a new transaction.

  If the busy flag F is reset, that is, if the settlement apparatus 12 is in a state capable of executing settlement of the transaction (YES in Act 21), the CPU 12a executes the processes of Act 22, Act 23 and Act 24. The processing procedures of Act 22, Act 23 and Act 24 are not limited to this order. The order may be reversed.

  At Act 22, the CPU 12 a sets the busy flag F to “1”.

  In Act 23, the CPU 12a instructs the communication unit 12j to transmit command data of an accounting enable response to the registration device 11 of the data transmission source. In response to this command, the communication unit 12 j sets the registered device ID set as the transmission source of “accounting data + list data” as the destination, and the command data of the accounting-enabled response with the settlement device ID stored in the ROM 12 b as the transmission source. On the LAN 13. The command data is received by the registration device 11 whose registration device ID as the destination matches the registration device ID stored in the ROM 11 b.

  In Act 24, the CPU 12a executes accounting processing based on the received accounting data. Accounting will be described later. When the accounting process is completed, the CPU 12a resets the busy flag F to "0" (Act 25).

  Above, the reception interruption process of "accounting data + list data" in the state where busy flag F is reset is completed.

  On the other hand, when the busy flag F is set, that is, when the settlement apparatus 12 can not execute settlement of the transaction (NO in Act 21), the CPU 12a searches the received list data (Act 26). . Then, the CPU 12a checks whether the settlement device ID stored in the ROM 12b is associated with the final list number of the list data (Act 27).

  If the settlement device ID is not associated with the final list number (NO in Act 27), the CPU 12a is a list number obtained by adding “1” to the list number with which the settlement device ID stored in the ROM 12b is associated. The settlement device ID associated with the ID is detected (Act 28). Then, the CPU 12a instructs the communication unit 12j to transmit "accounting data + list data" to the detected payment apparatus ID as a destination (Act 29). In response to this command, the communication unit 12 j transmits “accounting data + list data” to the LAN 13 with the detected payment apparatus ID as the destination and the registered apparatus ID indicating the transmission source as it is. The “accounting data + list data” is received by the settlement apparatus 12 whose settlement apparatus ID as the destination matches the settlement apparatus ID stored in the ROM 12 b.

  On the other hand, when the settlement device ID is associated with the final list number (the maximum value of the list number) (YES in Act 27), the CPU 12a sends an accounting impossible response to the registration device 11 of the data transmission source. It instructs the communication unit 12 j to transmit command data (Act 30). In response to this command, the communication unit 12j sets the registration apparatus ID set as the transmission source of "accounting data + list data" as the destination, and the command data of the accounting impossible response whose transmission source is the settlement apparatus ID stored in the ROM 12b. On the LAN 13. The command data is received by the registration device 11 whose registration device ID as the destination matches the registration device ID stored in the ROM 11 b.

  Thus, the reception interrupt process of “accounting data + list data” with the busy flag F set is completed.

  The CPU 11a of the registration device 11 that has transmitted "accounting data + list data" in Act 15 of FIG. 7 waits for a response from the settlement device 12 (Act 16). When command data indicating a response is received via the communication unit 11j (YES in Act 16), the CPU 11a identifies whether the command data is an accounting-enabled response or an accounting-impossible response (Act 17).

  In the case of an accountable response (YES in Act 17), the CPU 11a searches the list table 42, and reads out the identification name stored in association with the settlement device ID that is the transmission source of the command data. Then, the CPU 11a displays a message indicating that preparation for the accounting is completed by the settlement apparatus 12 of this identification name in a partial area of the accounting confirmation screen (Act 18). The store clerk who confirms this message notifies the shopper to perform accounting in the settlement apparatus 12 specified from the identification name.

  On the other hand, in the case of the accounting non-permission response (NO in Act 17), the CPU 11a displays a message indicating that accounting data could not be transmitted in a partial area of the accounting confirmation screen (Act 19). Thereafter, the CPU 11a executes a transmission disabling process.

  The transmission disabling process waits, for example, for the accounting button to be input again, and when the accounting button is input, the processing after Act 13 is executed again. In this case, the clerk who confirmed the message touches the accounting button.

  In the transmission disabling process, for example, the accounting data is attached with a unique identification code and transmitted to the server address, and the printer 11h is driven to issue an accounting ticket on which a bar code indicating the identification code is printed. In this case, the clerk who has confirmed the message gives a bill to the shopper. The shopper, for example, causes the scanner 12f of the settlement apparatus 12 prepared at a place different from the checkout lane to read the barcode of the bill. Then, the CPU 12a of the settlement apparatus 12 acquires, from the server, the accounting data attached by the identification code obtained from the bar code. Then, the CPU 12a executes the processes of Act22, Act24 and Act25 of FIG. 8 based on the accounting data.

  Thus, the store clerk 21 registers the product purchased by the shopper 22 in the registration device 11. Then, when the registration is completed, the store clerk 21 touches the accounting button on the accounting confirmation screen. Then, the accounting data necessary for settling the transaction with the shopper 22 is transmitted together with the list data of the list table 42. The transmission destination of the “accounting data + list data” is the settlement apparatus 12 (set as the settlement apparatus 12-1) identified by the settlement apparatus ID of the list number “1”.

  Here, if the settlement apparatus 12-1 can execute settlement of the transaction (busy flag F = 0), command data of an accounting-enabled response is transmitted from the settlement apparatus 12-1 to the registration apparatus 11. As a result, the accounting confirmation screen of the registration device 11 displays a message indicating that preparation for accounting has been completed together with the identification name representing the settlement device 12-1, so the clerk 21 settles the shopper 22 Informing device 12-1 to perform accounting.

  On the other hand, if the settlement device 12-1 can not execute settlement of the transaction (busy flag F = 1), "accounting data + list data" is converted from the settlement device 12-1 to the other settlement device 12 Ru. The conversion destination is the settlement apparatus 12 (set as the settlement apparatus 12-2) identified by the settlement apparatus ID of the list number "2".

  Here, if the settlement apparatus 12-2 can execute settlement of the transaction (busy flag F = 0), command data of an accounting-enabled response is transmitted from the settlement apparatus 12-2 to the registration apparatus 11. As a result, on the accounting confirmation screen of the registration device 11, a message indicating that preparation for accounting has been made is displayed together with the identification name representing the settlement device 12-2, so the clerk 21 settles the shopper 22 It is notified that the accounting will be performed by the device 12-2.

  On the other hand, if the settlement device 12-2 can not execute settlement of the transaction (busy flag F = 1), "accounting data + list data" is further converted from the settlement device 12-2 to the other settlement device 12 Be done. The conversion destination is the settlement apparatus 12 (set as the settlement apparatus 12-3) identified by the settlement apparatus ID of the list number "3".

  Here, if the settlement apparatus 12-3 can execute settlement of the transaction (busy flag F = 0), command data of an accounting-enabled response is transmitted from the settlement apparatus 12-3 to the registration apparatus 11. As a result, on the accounting confirmation screen of the registration device 11, a message indicating that the preparation for accounting has been completed is displayed together with the identification name representing the settlement device 12-3. Therefore, the clerk 21 settles the shopper 22 It announces that it performs accounting with the device 12-3.

  On the other hand, if the settlement device 12-3 can not execute the settlement of the transaction (busy flag F = 1), the settlement of the transaction is performed by all of the three settlement devices 12-1, 12-2, 12-3. Is impossible. In this case, command data of the accounting impossible response is transmitted from the settlement apparatus 12-3 to the registration apparatus 11. As a result, a message indicating that transmission is not possible is displayed on the accounting confirmation screen of the registration device 11, so the clerk 21 touches the accounting button again. Alternatively, since the accounting ticket is issued together with the non-transmission message, the clerk 21 passes the accounting ticket to the shopper 22.

  The shopper 22 who has been notified by the store clerk 21 to perform accounting with one of the settlement devices 12 moves to the location of the settlement device 12. At this time, the settlement apparatus 12 starts accounting processing in accordance with the settlement program. When the accounting process is started, the CPU 12a of the settlement apparatus 12 sets the screen of the touch panel 12g as the payment means selection screen SC1 (see FIG. 12) (Act 31).

  FIG. 12 is an example of the payment method selection screen SC1. Payment means selection screen SC1 includes display areas R1 and R2 and buttons B1 and B2. The display area R1 displays operation guidance for the settler who operates the settlement apparatus 12 (usually, the shopper 22). The display area R2 displays the total number and the total amount stored in the total memory 32b. The total number and the total amount stored in the total memory 32 b are values calculated by the settlement device 12 based on the unit price, the number, and the amount of the sales product included in the accounting data, as in the registration device 11. Note that the value calculated by the registration device 11 may be used as it is. The button B1 is a payment button B1 for the settler to select one of a plurality of payment means.

  The payment button B1 is a cash button B11 operated by the settler when the payment means is cash, a credit button B12 operated by the settler when the payment means is a credit card, and the settler when the payment means is electronic money And an electronic money button B13 operated by the user. A button B2 is a store clerk call button B2 operated by the settler when the store clerk 21 is called.

  The settler who confirms the payment means selection screen SC1 determines the payment means for the payment, and touches the payment button B1 corresponding to the payment means.

  The CPU 12a having displayed the payment means selection screen SC1 confirms whether the cash button B11 has been touched (Act 32). When the cash button B11 is not touched (NO in Act 32), the CPU 12a checks whether the credit button B12 is touched (Act 33). When the credit button B12 is not touched (NO in Act 33), the CPU 12a confirms whether the electronic money button B13 is touched (Act 34). If the electronic money button B13 is not touched (NO in Act 34), the CPU 12a checks again whether the cash button B11 is touched (Act 32). Thus, the CPU 12a waits for any one of the cash button B11, the credit button B12, and the electronic money button B13 to be touched as Act 32 to Act 34.

  In the present embodiment, cash, a credit card and electronic money are illustrated as payment means. At the time of payment by credit card or electronic money, card data of a credit card or electronic money card is read via the card reader / writer 12i. By reading these card data, personal information of the settler who is the card holder is taken into the settlement apparatus 12. Here, payment means by credit card or electronic money corresponds to a first payment means. On the other hand, at the time of payment by cash, the settler inserts cash into the bill insertion slot 125 or the coin insertion slot 123. Then, when the settlement by cash is completed and there is a change, the bill as the change is paid out from the bill payout port 126 and the coin is paid out from the coin payout port 124. Here, the cash payment means corresponds to a second payment means.

  Therefore, the computer mainly composed of the CPU 12a executes the processing of Act 32, Act 33 and Act 34 in cooperation with the touch panel 12g, thereby declaring whether the payment is to be made by the first payment means or by the second payment means. It will be accepted. That is, the first accepting means is realized.

  When the CPU 12a detects that the electronic money button B13 is touched in Act 32 to Act 34 standby state (Act 34, YES), the CPU 12a sets the screen of the touch panel 12g as the electronic money reception screen SC2 (see FIG. 13) (Act 35) .

  FIG. 13 is an example of the electronic money reception screen SC2. The electronic money reception screen SC2 includes a button B3 in addition to the display areas R1 and R2 and the store clerk call button B2 similar to the payment means selection screen SC1. The button B3 is a return button B3 operated by the settler when the previous operation is canceled to return to the previous screen.

  The settler who confirms the electronic money reception screen SC2 causes the card reader / writer 12i to read the data of the electronic money card when continuing the payment with the electronic money. On the other hand, in the case of stopping the payment by the electronic money, the payer touches the return button B3. When calling a store clerk, the payer touches the store clerk call button B2.

  The CPU 12a having displayed the electronic money reception screen SC2 determines whether the return button B3 is touched (Act 36). If the return button B3 is not touched (Act 36, NO), the CPU 12a determines whether the store clerk call button B2 is touched (Act 37). If the store clerk call button B2 is not touched (Act 37, NO), the CPU 12a determines whether payment data by electronic money is input (Act 38). The payment data of electronic money is balance data of electronic money recorded in an electronic money recording medium such as an electronic money card. The input of the payment data means that the balance data of electronic money recorded in the electronic money recording medium is read by the card reader / writer 12i. When payment data by electronic money is not input (Act 38, NO), the CPU 12a checks again whether the return button B3 is touched (Act 36). Thus, the CPU 12a waits for the return button B3 or the store clerk call button B2 to be touched as Act 36 to Act 38, or the input of payment data by electronic money.

  When the CPU 12a detects that the return button B3 is touched in the standby state of Act 36 to Act 38 (Act 36, YES), it returns to the process of Act 31. That is, the CPU 12a returns the screen of the touch panel 12g from the electronic money reception screen SC2 to the payment means selection screen SC1.

  Therefore, the computer mainly composed of the CPU 12a executes the process of Act 36 in cooperation with the touch panel 12g to thereby receive the declaration for paying the charge with the electronic money which is a kind of the first payment means by the first reception means In this case, the instruction to return to the state of accepting the declaration of whether to pay the payment by the first payment means or the second payment means is received here.

  Further, the computer mainly composed of the CPU 12a executes the processing of Act 36 and Act 31 to receive a declaration for paying the payment with the electronic money which is a type of the first payment means by the first reception means, and then declares the declaration. It will return to the state to accept. That is, the return means is realized.

  The CPU 12a controls the communication unit 12j to transmit a store clerk call signal to the registration device 11 when detecting that the store clerk call button B2 is touched in Act 36 to Act 38 standby state (Act 37, YES). To do (Act 39). By this control, a clerk call signal is transmitted from the communication unit 12 j to the registration device 11 via the LAN 13. In the registration device 11 that has received the clerk calling signal, for example, a message for notifying the operator of the settlement device 12 being called by the clerk is displayed on the touch panel 11g1 on the clerk side.

  The CPU 12a that controls the transmission of the store clerk calling signal sets the screen of the touch panel 12g as the store clerk calling screen (Act 40). The store clerk call screen includes, for example, a message for notifying a settler that a store clerk is being called. Above, CPU12a ends accounting processing.

  When the CPU 12a detects that the electronic money balance data recorded on the electronic money recording medium such as the electronic money card is read by the card reader / writer 12i in the standby state from Act 36 to Act 38, the payment data by the electronic money is Judge as input. If it is determined that the payment data by electronic money is input (Act 38, YES), the CPU 12a executes payment processing of electronic money (Act 41). Since this process is a well-known process of debiting the transaction from the balance of the electronic money, the detailed description will be omitted.

  Therefore, the computer mainly composed of the CPU 12a cooperates with the card reader / writer 12i to execute the process of Act 38, thereby declaring that the first accepting means declares payment using electronic money, which is a type of first payment means. If accepted, it means that the input of payment data by electronic money is accepted. That is, part of the second accepting means is realized.

  When the computer mainly composed of the CPU 12a executes the process of Act 41, the second accepting means accepts the input of payment data by electronic money, which is a type of the first payment means, by the electronic money. The payment will be settled based on the payment data. That is, part of the settlement means is realized.

  Thus, when the electronic money payment process is completed, the CPU 12a sets the screen of the touch panel 12g as the payment end screen (Act 42). The payment end screen includes a message for notifying the settler that payment for the payment has been completed. Above, CPU12a ends accounting processing.

  When the CPU 12a detects that the credit button B12 is touched in the standby state of Act 32 to Act 34 (Act 33, YES), it proceeds to Act 51 of FIG. That is, the CPU 12a sets the screen of the touch panel 12g as a card reception screen (Act 51). The card acceptance screen is the same except that the messages on the electronic money acceptance screen SC2 and the display area R1 are different. In the case of the electronic money reception screen SC2, for example, a message "Please let me read the electronic money by the reading unit" is displayed in the display area R1, but in the case of the card reception screen, for example "reading data of credit card" The message "Please read by the department" is displayed. The card reception screen is the same as the electronic money reception screen SC2 in that a return button B3 is displayed in addition to the store clerk call button B2.

  The settler who confirms the card reception screen causes the card reader / writer 12i to read the data of the credit card when continuing the payment by the credit card. On the other hand, in the case of canceling the payment by the credit card, the payer touches the back button B3. When calling a store clerk, the payer touches the store clerk call button B2.

  Having displayed the card reception screen, the CPU 12a determines whether the back button B3 has been touched (Act 52). When the return button B3 is not touched (Act 52, NO), the CPU 12a determines whether the store clerk call button B2 is touched (Act 53). If the store clerk call button B2 is not touched (Act 53, NO), the CPU 12a determines whether data of a credit card has been input (Act 54). If the data of the credit card is not input (Act 54, NO), the CPU 12a checks again whether the return button B3 is touched (Act 52). Thus, as Act 52 to Act 54, the CPU 12a waits for the return button B3 or the store clerk calling button B2 to be touched or for the data of the credit card to be input.

  When the CPU 12a detects that the return button B3 is touched in the standby state of Act 52 to Act 54 (Act 52, YES), the CPU 12a returns to the process of Act 31. That is, the CPU 12a returns the screen of the touch panel 12g from the card reception screen to the payment means selection screen SC1.

  Therefore, the computer mainly composed of the CPU 12a executes the process of Act 52 in cooperation with the touch panel 12g to thereby receive the declaration for paying the payment by the credit card, which is a type of the first payment means, by the first reception means. In this case, the instruction to return to the state of accepting the declaration of whether the payment is to be made by the first payment means or the second payment means is received.

  The computer mainly composed of the CPU 12a executes the processing of Act 52 and Act 31 to receive a declaration to pay the payment with the credit card, which is a type of the first payment means, by the first reception means, and then declares the declaration. It will return to the state to accept. That is, the return means is realized.

  When the CPU 12a detects that the store clerk call button B2 is touched in the standby state from Act 52 to Act 54 (Act 53, YES), the CPU 12a sends a store clerk call signal to the registration device 11 as in the process of Act 39 described above. The communication unit 12 j is controlled to transmit (Act 55). Further, the CPU 12a sets the screen of the touch panel 12g as a store clerk calling screen, as in the case of the process of Act 40 described above (Act 56). Above, CPU12a ends accounting processing.

  Further, when detecting that the data of the credit card is read by the card reader / writer 12i in the standby state of Act 52 to Act 54, the CPU 12a determines that the payment data by the credit card is input. Payment data by credit card is data for authentication recorded on a credit card. If it is determined that payment data by credit card is input (Act 54, YES), the CPU 12a executes payment processing of a credit card (Act 57). Since this process is a known process including credit card authentication, the detailed description will be omitted.

  Therefore, the computer mainly composed of the CPU 12a executes the process of Act 54 in cooperation with the card reader / writer 12i, thereby declaring that the first accepting means declares payment using a credit card, which is a type of first payment means. If accepted, it means that the input of payment data by credit card is accepted. That is, part of the second accepting means is realized.

  When the computer mainly composed of the CPU 12a executes the process of Act 57, the second accepting means accepts the input of payment data from the credit card, which is a type of the first payment means, by the credit card. The payment will be settled based on the payment data. That is, part of the settlement means is realized.

  Thus, when the credit card payment process is completed, the CPU 12a sets the screen of the touch panel 12g as the payment end screen (Act 58). The payment end screen includes a message for notifying the settler that payment for the payment has been completed. Above, CPU12a ends accounting processing.

  When the CPU 12a detects that the cash button B11 is touched in the standby state of Act 32 to Act 34 (Act 32, YES), it proceeds to Act 61 of FIG. That is, the CPU 12a sets the screen of the touch panel 12g as the cash reception screen SC3 (see FIG. 14) (Act 61).

  FIG. 14 is an example of the cash reception screen SC3. The cash acceptance screen SC3 includes a display area R3 and a store clerk call button B2 in addition to the display area R1 similar to the payment means selection screen SC1. However, the back button B3 displayed on the electronic money reception screen SC2 or the credit card reception screen is not displayed. The display area R3 is an area for displaying the total amount, the input amount and the change amount.

  The settler who confirms the cash reception screen SC3 inserts cash into the bill insertion slot 125 or the coin insertion slot 123 of the automatic change machine 12e when continuing the payment with cash. On the other hand, when canceling cash payment or calling a clerk, the settler touches the clerk call button B2.

  The CPU 12a having displayed the cash acceptance screen SC3 determines whether the store clerk call button B2 is touched (Act 62). If the store clerk call button B2 is not touched (Act 62, NO), the CPU 12a determines whether cash has been inserted into the automatic change machine 12e (Act 63). If cash is not inserted (Act 63, NO), the CPU 12a checks again whether the store clerk call button B2 is touched (Act 62). Thus, as Act 62 and Act 63, the CPU 12a waits for the store clerk call button B2 to be touched or for cash to be inserted.

  When the CPU 12a detects that the store clerk call button B2 is touched in the standby state of Act 62 and Act 63 (Act 62, YES), the registration device 11 registers the store clerk call signal as in the process of Act 39 and Act 55 described above. The communication unit 12 j is controlled to transmit to (Act 69). Further, the CPU 12a sets the screen of the touch panel 12g as a store clerk calling screen (Act 70), as in the processes of Act 40 and Act 56 described above. Above, CPU12a ends accounting processing.

  Incidentally, the called clerk can return the screen of the touch panel 12g to the payment means selection screen SC1 by performing a predetermined return operation after switching the operation mode of the settlement apparatus 12 to the clerk mode. That is, the settlement apparatus 12 has a second return means different from the return means. Therefore, the settler who has stopped paying cash can pay for it by other payment means, such as a credit card or electronic money, depending on which the clerk is called. The return means is a means by which any settler can return the screen of the touch panel 12g to the payment means selection screen SC1. On the other hand, the second return means is a means which can return only a limited person such as a store clerk.

  When detecting that a bill or coin is inserted into the bill insertion slot 125 or the coin insertion slot 123 of the automatic change machine in the standby state of Act 62 and Act 63, the CPU 12a determines that cash payment data is input. If it is determined that cash payment data has been input (Act 63, YES), the CPU 12a calculates a deposit amount (Act 64). Then, the CPU 12a determines whether the deposit amount is equal to or more than the payment amount (Act 65). If the deposit amount does not reach the payment amount (Act 65, NO), the CPU 12a returns to the standby state of Act 62 and Act 63. Therefore, if cash is further input (Act 63, YES), the deposit amount is added. When the CPU 12a confirms that the deposit amount is equal to or more than the payment amount (Act 65, YES), the CPU 12a sets the screen of the touch panel 12g as an accounting waiting screen SC4 (see FIG. 15) (Act 66).

  FIG. 15 is an example of the accounting wait screen SC4. The accounting waiting screen SC4 is a screen obtained by adding the accounting button B4 to the cash accepting screen SC3.

  Therefore, the computer mainly composed of the CPU 12a executes the process of Act 63 in cooperation with the automatic change machine 12e to receive the declaration to pay the money by the first receiving means with cash which is a type of the second payment means. In this case, the input of payment data in cash is accepted. That is, part of the second accepting means is realized. On the other hand, when the computer mainly composed of the CPU 12a receives the declaration to pay the price by cash which is the second payment means by the first reception means, the payment by the first payment means or the second payment I do not accept the instruction to return to the state to accept the declaration of payment by means.

  The settler who confirms the accounting waiting screen SC4 touches the accounting button B4 when completing the payment in cash. On the other hand, when calling a store clerk, the settler touches the store clerk call button B2.

  The CPU 12a that has displayed the accounting wait screen SC4 determines whether the store clerk call button B2 has been touched (Act 67). If the store clerk call button B2 is not touched (Act 67, NO), the CPU 12a determines whether the accounting button B4 is touched (Act 68). If the accounting button B4 is not touched (Act 68, NO), the CPU 12a checks again whether the store clerk calling button B2 is touched (Act 67). Thus, the CPU 12a waits for the clerk calling button B2 to be touched or the accounting button B4 to be touched as Act 67 and Act 68.

  The CPU 12a controls the communication unit 12j to transmit a store clerk call signal to the registration device 11 when detecting that the store clerk call button B2 is touched in Act 67 and Act 68 standby states (Act 67, YES). (Act 69). Further, the CPU 12a sets the screen of the touch panel 12g as a clerk calling screen (Act 70). Above, CPU12a ends accounting processing.

  On the other hand, when the CPU 12a detects that the accounting button B4 is touched in the standby state of Act 67 and Act 68 (Act 68, YES), it executes cash payment processing (Act 71). This process is a well-known process of calculating the change amount by subtracting the payment amount from the deposit amount which is cash inserted from the bill input port 125 or the coin input port 123. The cash corresponding to the change amount is paid out from the bill payout opening 126 or the coin payout opening 124 of the automatic change machine 12e. In addition, the printer 12h is driven, and the receipt is printed and issued.

  Therefore, when the computer mainly composed of the CPU 12a executes the process of Act 71, the second accepting means accepts the input of payment data by cash which is a type of the second payment means, the payment data by cash concerned It will be settled on the basis of. That is, part of the settlement means is realized.

  Thus, when the cash payment process is completed, the CPU 12a sets the screen of the touch panel 12g as the payment end screen (Act 72). The payment end screen includes a message for notifying the settler that payment for the payment has been completed. Above, CPU12a ends accounting processing.

  As described above, according to the settlement apparatus 12 of the present embodiment, when the settler selects the credit card or the electronic money as the payment means on the payment means selection screen SC1, the screen of the touch panel 12g is the credit acceptance screen or the electronic money acceptance It becomes screen SC2. A return button B3 is displayed on the credit acceptance screen or the electronic money acceptance screen SC2. Therefore, the settler can return the screen of the touch panel 12g to the payment means selection screen SC1 by touching the back button B3.

  On the other hand, when the settler selects cash as the payment means, the screen of the touch panel 12g becomes the cash acceptance screen SC3, but the return button B3 is not displayed on the cash acceptance screen SC3. Therefore, the settler can not return the screen of the touch panel 12g to the payment means selection screen SC1. That is, even if the settler selects cash as the payment means, inserts cash less than the payment, and operates the "Return" button, it can not be executed even if the payment is left unpaid and the fraud is executed. Therefore, it is possible to prevent unpaid fraud in advance when cash is used as the payment means.

Generally, such fraud is a medium for inputting payment data, that is, a cash slot 123, a bill slot 125), and a medium related to the input of the payment data, that is, a change outlet Because (coin dispensing outlet 124, bill dispensing outlet 126) is different, the clerk is less likely to notice. According to the present embodiment, as described above, since the return button B3 is not displayed on the cash reception screen SC3, this kind of fraud can be reliably prevented.
A medium for inputting payment data is cash in the case of cash payment, a credit card in the case of credit payment, and an electronic money recording medium such as an electronic money card in the case of electronic money payment. is there. The medium associated with the input of the payment data is money equivalent to the change or the amount of money inserted in the case of cash payment, and is the inserted credit card in the case of credit payment, and in the case of electronic money payment. Is the inserted electronic money recording medium.

On the other hand, in the case of a credit card or electronic money as payment means, the information on the settler who is the card holder can be acquired by the settlement apparatus 12. The information on the settler is, for example, a name, an address, a telephone number and the like. Therefore, there is a low possibility that fraudulent use will be made to leave the account unpaid by misusing the return button B3 in the same manner as when the payer is cash. For this reason, there is no problem even if the button B3 for returning is displayed on the credit acceptance screen or the electronic money acceptance screen SC2. Therefore, the settler who selects the credit card or the electronic money as the payment means does not call the store clerk. Can be changed to Further, even in the case of cash payment, if the information on the settler can be obtained, a back button may be displayed. For example, after the payment terminal 12 obtains a membership card from which information on the payer can be obtained, a return button may be displayed.
The acquired information on the settler is stored in the auxiliary storage unit 11 d in association with the identifier for identifying the transaction.

Second Embodiment
In the first embodiment, the return button B3 is not displayed on the cash acceptance screen SC3 displayed on the touch panel 12g when the settler selects cash as the payment means. However, it is assumed that there is a settler who wants to change to another means of payment after cash has been selected as the means of payment, but before the input of cash. Before the cash is inserted, even if the return button is operated, the cash is not paid out from the bill dispensing outlet 126 or the coin dispensing outlet 124 of the automatic change machine 12e.

  Therefore, when cash is selected as the payment means, the button B3 for returning to the payment means selection screen SC1 is displayed until cash is inserted, and the second embodiment enables the return to the payment method selection screen SC1. Will be described with reference to FIG. 16 and FIG. Note that FIGS. 1 to 11 described in the first embodiment, and FIGS. 12, 13, and 15 are used as they are in the second embodiment, and the description thereof is omitted here.

  FIG. 16 is a flowchart showing a main procedure of information processing executed by the CPU 12a of the settlement apparatus 12 according to the settlement program after the cash button B11 is touched in Act 32 of FIG. The contents of the processes described below are merely examples, and various processes that can obtain similar results can be appropriately used.

  When the CPU 12a detects that the cash button B11 is touched in the standby state of Act 32 to Act 34 (Act 32, YES), the CPU 12a proceeds to Act 81 of FIG. That is, the CPU 12a sets the screen of the touch panel 12g as the cash reception screen SC5 (see FIG. 17) (Act 81).

  FIG. 17 is an example of the cash reception screen SC5. The cash acceptance screen SC5 is a screen in which a button B3 for returning to the cash acceptance screen SC3 of the first embodiment is added.

  The settler who confirms the cash reception screen SC5 inserts cash into the bill insertion slot 125 or the coin insertion slot 123 of the automatic change machine 12e when continuing the payment with cash. On the other hand, when canceling the cash payment, the payer touches the back button B3. When calling a store clerk, the payer touches the store clerk call button B2.

  Having displayed the cash acceptance screen SC5, the CPU 12a determines whether the return button B3 has been touched (Act 82). If the return button B3 is not touched (Act 82, NO), the CPU 12a determines whether the store clerk call button B2 is touched (Act 83). If the store clerk call button B2 is not touched (Act 83, NO), the CPU 12a determines whether cash has been inserted into the automatic change machine 12e (Act 84). When cash is not inserted (Act 84, NO), the CPU 12a checks again whether the return button B3 is touched (Act 82). Thus, the CPU 12a waits for either the return button B3 or the store clerk call button B2 to be touched or an input of cash payment data as Act 82 to Act 84.

  If the CPU 12a detects that the return button B3 has been touched in the standby state of Act 82 to Act 84 (Act 82, YES), it returns to the process of Act 31. That is, the CPU 12a returns the screen of the touch panel 12g from the cash acceptance screen SC5 to the payment means selection screen SC1.

  On the other hand, when the CPU 12a detects that the store clerk call button B2 is touched in the standby state from Act 82 to Act 84 (Act 83, YES), the communication unit 12 j transmits the store clerk call signal to the registration device 11. Control (Act 95). Further, the CPU 12a sets the screen of the touch panel 12g as a clerk calling screen (Act 96). Above, CPU12a ends accounting processing.

  Further, when detecting that a bill or coin has been inserted into the bill insertion slot 125 or the coin insertion slot 123 of the automatic change machine in the standby state from Act 82 to Act 84, the CPU 12a determines that cash is input as payment data. If it is determined that cash has been input (Act 83, YES), the CPU 12a deletes the return button B3 from the cash reception screen SC5 (Act 84). The CPU 12a also calculates the amount of payment (Act 86). Then, the CPU 12a determines whether the deposit amount is equal to or more than the payment amount (Act 87). If the deposit amount is less than the payment amount (Act 87, NO), the CPU 12a determines whether the store clerk call button B2 is touched (Act 88). If the store clerk call button B2 is not touched (Act 88, NO), the CPU 12a determines whether cash has been inserted into the automatic change machine 12e (Act 89). When cash is not inserted (Act 89, NO), the CPU 12a checks again whether the store clerk call button B2 is touched (Act 88). Thus, as Act 88 and Act 89, the CPU 12a waits for the store clerk calling button B2 to be touched or for input of payment data by cash.

  When the CPU 12a detects that the store clerk call button B2 is touched in the standby state of Act 88 and Act 89 (Act 88, YES), the CPU 12a executes the process of Act 95 and Act 96 described above.

  When the CPU 12a detects that cash payment data has been input in the standby state of Act 88 and Act 89, the CPU 12a executes the processing of Act 86 and Act 87 described above. Therefore, if cash is further input (Act 89, YES), the deposit amount is added. When the CPU 12a confirms that the payment amount has become equal to or more than the payment amount (Act 87, YES), the CPU 12a sets the screen of the touch panel 12g as an accounting waiting screen SC4 (Act 90).

  Thereafter, the CPU 12a executes the same processes as Act 67 to Act 70 of the first embodiment as Act 91 to Act 96.

  Therefore, the computer mainly composed of the CPU 12a executes the processing of Act 81 to Act 89 in cooperation with the touch panel 12g, thereby receiving the declaration for paying the payment by the cash as the second payment means by the first reception means, and When the second accepting means accepts the input of payment data by cash, the instruction to return to the state of accepting the above declaration is not accepted.

  As described above, in the second embodiment, when the cash button B11 is touched and cash is selected as the payment means, a button B3 for returning to the cash acceptance screen SC5 displayed thereafter is displayed. The return button B3 is erased from the cash acceptance screen SC5 when cash is inserted into the automatic change machine 12e. Therefore, the settler who has selected cash as the settlement means can return the screen of the touch panel 12g to the payment means selection screen SC1 by touching the return button B3 before inserting the cash.

  On the other hand, since the return button B3 is deleted when cash is inserted, the settler can not operate the return button B3. Therefore, in the second embodiment as well, it is possible to prevent fraud that leaves without payment.

  Hereinafter, other embodiments will be described.

  The first embodiment exemplifies a first operation in which the return button B3 is not displayed on the cash reception screen SC3. In the second embodiment, cash is displayed in a state where the cash reception screen SC3 including the return button B3 is displayed. The second operation of deleting the return button B3 when it is pressed is illustrated. In another embodiment, the first operation and the second operation can be selected as options of the settlement apparatus 12. By doing so, it is possible to easily select whether to adopt the first operation or the second operation in the store where the settlement apparatus 12 is introduced.

  In the first and second embodiments, cash, a credit card and electronic money are illustrated as payment means, but the payment means is not limited to these. Other payment means may be added. Also, any payment means may be omitted.

  In that case, the first payment means is not limited to credit cards and electronic money. Likewise, the second means of payment is not limited to cash. The point is that the second payment means may be used as the second payment means for the payment means that may cause the fraud to leave unpaid due to the operation of the return button B3, and the first payment means may be used for the other payment means.

  In the first and second embodiments, the semi-self type checkout system of the type in which the registration device 11 transmits “accounting data + list data” to the accounting device 12 is exemplified, but the semi-self type check to which the settlement device 12 can be applied The out system is not limited to this. For example, the registration device 11 transmits accounting data to one settlement device 12 set in advance. The settlement apparatus 12 performs settlement processing based on the accounting data if settlement is possible, but transmits accounting data to another preset settlement apparatus when settlement is not possible. It may be a semi-self type checkout system of this type. For example, it may be a semi-self type checkout system of the type which transmits accounting data to one settlement device 12 selected by the store clerk in the registration device 11. The point is that the type of semi-self checkout system is not particularly limited. Further, for example, the same configuration as that of the present embodiment can be applied to a settlement apparatus of a self-type checkout system performed by a settlement person who is not a clerk until registration operation necessary for calculation of a payment.

  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.
