The link destination ID memory 44 is an area for storing the device ID of the registration machine 11 that is linked to the accounting machine 12.

Then, the checkout system 10 implements the control programs for realizing the respective functions A to G in one transaction on the registration machine 11 and the accounting machine 12, respectively.
4 and 5 are flow charts showing an information processing procedure for one transaction executed by the CPU 11a of the registration machine 11 according to a control program. 6 to 10 are flow charts showing an information processing procedure of one transaction executed by the CPU 12a of the accounting machine 12 according to the control program. 11 and 12 are schematic views showing an example of an image displayed on the touch panel 11f of the registration machine 11. FIG. 13 is a schematic view showing an example of an image displayed on the touch panel 12f of the accounting machine 12. Hereinafter, using these figures, information processing executed for one transaction by the registration machine 11 and the accounting machine 12 will be described. The content of the information processing described below is an example, and various information processing capable of obtaining similar results can be appropriately used.

First, the information processing executed by the registration machine 11 will be described with reference to FIGS. 4 and 5. This information processing follows a control program stored in the ROM 11b or the auxiliary storage unit 11d.

When the control program is started in the registration machine 11, the CPU 11a first clears the data buffer 31 as Act1 as shown in FIG. Next, the CPU 11a causes the registered image SC1 (see FIG. 11) to be displayed on a part of the screen of the touch panel 11f as Act2.

The registration image SC1 represents the contents of the data buffer 31 and causes the clerk 21 to confirm the implementation status of the registration process for one transaction. As shown in FIG. 11, the registered image SC1 includes display areas D1 and D2. The display area D1 displays the product name, unit price, number of items sold (quantity), and sales amount of the product to be purchased newly registered in the data buffer 31. The display area D1 also displays the total number of points and the total amount of all the registered products to be purchased. The display area D2 displays the product name, unit price, number of items sold (quantity), and sales amount of the product to be purchased registered in the data buffer 31 before the product shown in the display area D1 in a list format. Incidentally, at the time of Act2, since the data is not registered in the data buffer 31, the data is not displayed in the display areas D1 and D2.

Although not shown, the product button for the clerk 21 to specify the product and the registration of the product to be purchased to be registered as one transaction are completed outside the area of the touch panel 11f screen to be the registered image SC1. Various function buttons such as a subtotal button for specifying are displayed.

When the registered image SC1 is displayed, the CPU 11a confirms whether or not a link request command has been received from any accounting machine 12 as Act3. The link request command will be described in the information processing of the accounting machine 12 described later. When the link request command is not received (NO in Act3), the CPU 11a confirms whether or not the product code has been input as Act4. The product code is input via the scanner 11e or the touch panel 11f. If the product code is not entered (NO in Act4), the CPU 11a returns to the process of Act3. Therefore, in the processing of Act 3 and Act 4, the CPU 11a waits for the link request command to be received or the product code to be input.

When the product code is input in the standby state of Act3 and Act4 (YES in Act4), the CPU 11a registers the product sales data as Act5. That is, the CPU 11a acquires product information such as a product name and a unit price associated with the product code and set in the product database. Further, the CPU 11a calculates the amount of sales points, that is, the so-called sales amount, by multiplying this unit price by the number of sales points. The number of items sold is a numerical value when the number is placed by the numeric keypad or the like before the product code is input, and "1" when the number is not placed. Thus, the CPU 11a creates product sales data including a product code, a product name, a unit price, a number of items sold, and a sales amount. Then, the CPU 11a registers the product sales data in the data buffer 31.

When the product sales data has been registered, the CPU 11a updates the display areas D1 and D2 of the registered image SC1 based on the data in the data buffer 31 as Act6. After that, the CPU 11a returns to the standby state of Act3 and Act4. In this standby state, for example, when a subtotal button is input, the input is ignored.

When a link request command is received in the standby state of Act3 and Act4 (YES in Act3), the CPU 11a stores the device ID of the accounting machine 12 included as the source in the link request command as Act7 in the link destination ID memory 32. do. Next, the CPU 11a displays the linked image SC2 (see FIG. 12) as Act8. Further, the CPU 11a transmits a permission response command to the accounting machine 12 of the command transmission source as Act9. The permission response command includes the device ID of the registration machine 11 as a transmission source. The processing procedure of Act8 and Act9 is not limited to this. The front and back may be reversed.

As shown in FIG. 12, the link destination image SC2 represents information for guiding the customer 22 to the accounting machine 12 from which the link request command is transmitted. In FIG. 12, the linked image SC2 is displayed on the upper right of the registered image SC1. The display position of the linked image SC2 is not limited to the position shown in FIG. For example, it may be displayed in the center of the registered image SC1. In that case, the linked image SC2 includes a confirmation button so that the linked image SC2 is deleted when the confirmation button is touched.

When the processing of Act7 to Act9 is completed, the CPU 11a confirms whether or not the product code has been input as Act11, as shown in FIG. If the product code has not been entered (NO in Act 11), the CPU 11a confirms whether or not a communicate command has been received from the accounting machine 12 in the linked state as Act 12. The communicate command will be described in the information processing of the accounting machine 12 described later. When the communicate command has not been received (NO in Act12), the CPU 11a confirms whether or not the subtotal button has been input as Act13. If the subtotal button is not input, the CPU 11a returns to the process of Act11. Therefore, in the processing of Act 11 to Act 13, the CPU 11a waits for the product code to be input, the communicate command to be received, or the subtotal button to be input.

When the product code is input in the standby state of Act 11 to Act 13 (YES in Act 11), the CPU 11a executes the same processing as the processing of Act 5 and Act 6 described above. That is, the CPU 11a registers the product sales data as Act 14, and updates the display areas D1 and D2 of the registered image SC1 as Act 15. Further, the CPU 11a transmits display data including information on the product name, unit price, number of points sold and sales amount registered in the data buffer 31 as Act16 and information on the total points and total amount to the accounting machine 12 in the linked state. The communication unit 11h is controlled so as to do so. By this control, the display data destined for the device ID stored in the link destination ID memory 32 is transmitted to the LAN 13. This display data is received by the accounting machine 12 identified by the destination device ID. After controlling the transmission of the display data, the CPU 11a returns to the standby state of Act 11 to Act 13.

When a communicate command is received in the standby state of Act 11 to Act 13 (YES in Act 12), the CPU 11a displays a message, an icon, etc. corresponding to the command as Act 17 on the touch panel 11f. The details of this processing will be described in the information processing of the accounting machine 12 described later.

When the subtotal button is input in the standby state of Act 11 to Act 13 (YES in Act 13), the CPU 11a displays the transfer button on the touch panel 11f as Act 18. The transfer button may be displayed as part of the registered image SC1. Alternatively, the transfer button may be displayed outside the area of the touch panel 11f as the registered image SC1.

The CPU 11a waits for the transfer button to be input as Act 19. When the transfer button is input (YES in Act 19), the CPU 11a issues a new registered machine transaction number as Act 20. The registered machine transaction number is, for example, a number that increases by 1 in order from 1. When the registered machine transaction number is issued, the CPU 11a generates registered transaction data including the registered machine transaction number and the product sales data in the data buffer 31 as Act21. Then, the CPU 11a controls the communication unit 11h so as to transmit the registered transaction data to the accounting machine 12 in the linked state. By this control, the registration transaction data destined for the device ID stored in the link destination ID memory 32 is transmitted to the LAN 13. This registered transaction data is received by the accounting machine 12 identified by the destination device ID.

After controlling the transmission of the registered transaction data, the CPU 11a saves the registered transaction data in the journal file of the auxiliary storage unit 11d as Act22. Further, the CPU 11a clears the device ID stored in the link destination ID memory 32 as Act23. Further, the CPU 11a erases the linked image SC2 displayed on the touch panel 11f as Act24. The processing order of Act 22 to Act 24 is not limited to this. The front and back may be interchanged as appropriate.
When the processing of Act 20 to Act 24 is completed, the CPU 11a ends the information processing for one transaction. Then, the CPU 11a starts the process again from Act1.

Next, the information processing executed by the accounting machine 12 will be described with reference to FIGS. 6 to 10. This information processing follows a control program stored in the ROM 12b or the auxiliary storage unit 12d.

When the control program is started in the accounting machine 12, as shown in FIG. 6, the CPU 12a first sets the device status ST to “0” as Act31. Further, the CPU 12a causes the default image to be displayed on a part of the screen of the touch panel 11f as Act32.
The default image is arbitrary. For example, the message "Welcome" may be displayed. Alternatively, an advertisement image of a promotional product may be displayed.

The device status ST is information representing the state of the accounting machine 12, and is stored in, for example, the auxiliary storage unit 12d. In the present embodiment, the device status ST when not linked to the registration machine 11 is set to "0". The device status ST when the registration machine 11 is linked and the pre-accounting process can be performed is set to "1". When the registered transaction data is received from the registered machine in the linked state and the accounting process is possible, the device status ST is set to "2".

The pre-accounting process is a process of accepting a customer to prepare for payment. For example, in the case of cash payment, the pre-accounting process is the process of accepting the deposit of banknotes and coins of an appropriate amount with the automatic change machine 12 m. In the case of electronic money payment, the process of inquiring the balance of electronic money or accepting the charge of electronic money is the pre-accounting process. In the case of credit card payment, the process of reading credit card data is the pre-accounting process.

Accounting is the process of completing a customer's payment. For example, in the case of cash payment, the deposit amount inserted into the automatic change machine 12 m is used as the deposit amount, and the process of calculating the change amount and paying out from the automatic change machine 12 m is the accounting process. In the case of electronic money payment, the processing of reducing the payment amount from the balance of electronic money is the accounting process. In the case of credit card payment, the process of authenticating the credit card is the accounting process.

The CPU 12a confirms the device status ST as Act 33. At this point, since the device status ST is “0”, the CPU 12a communicates with another accounting machine 12 via LAN 13 as Act 34, and sets the device status ST to “0”. Explore. Then, the CPU 12a refers to the selection table T1 as Act35 and determines whether or not it is the highest priority accounting machine. The highest priority accounting machine is the accounting machine 12 having the highest priority among the accounting machines 12 in which the device status ST is set to “0” with respect to the registration machine 11. When it becomes the highest priority accounting machine for a plurality of registration machines 11, it becomes the highest priority accounting machine for the registration machine 11 having the highest priority.

A specific example of the process of determining the highest priority accounting machine will be described with reference to the selection table T1 of FIG. As an example, the device status of all accounting machines 12 is set to "0". In this case, with respect to the registration machine 11 of the device ID "R1", the accounting machine having the highest priority, that is, the accounting machine 12 of the device ID "A2" is the highest priority accounting machine. For the registration machine 11 of the device ID "R2", the accounting machine having the highest priority, that is, the accounting machine 12 of the device ID "A4" is the highest priority accounting machine. For the registration machine 11 of the device ID "R3", the accounting machine having the highest priority, that is, the accounting machine 12 of the device ID "A6" is the highest priority accounting machine. Accounting machines 12 with other device IDs "A1", "A3" and "A5" do not have the highest priority.

As another example, it is assumed that the device status of the accounting machine 12 other than the device ID "A2" is "0". In this case, with respect to the registration machine 11 of the device ID "R1", the accounting machine having the second highest priority, that is, the accounting machine 12 of the device ID "A1" is the highest priority accounting machine.

As yet another example, the device status of the accounting machine 12 of the device IDs "A1", "A2", and "A3" is not "0", but the accounting of the device IDs "A4", "A5", and "A6". It is assumed that the device status of the machine 12 is "0". In this case, with respect to the registration machine 11 of the device ID "R1", the accounting machine having the fourth highest priority, that is, the accounting machine 12 of the device ID "A4" is the highest priority accounting machine. However, the accounting machine 12 with the device ID "A4" has the highest priority with respect to the registered machine 11 with the device ID "R2" and becomes the highest priority accounting machine. Therefore, for the registration machine 11 of the device ID "R1", the accounting machine having the fifth priority, that is, the accounting machine 12 of the device ID "A5" is the highest priority accounting machine.

If it is determined in Act35 that it is not the highest priority accounting machine (NO in Act35), the CPU 12a returns to the processing of Act33. Therefore, in this case, since the device status ST remains “0”, the CPU 12a repeats the processes of Act 34 to Act 35.

If it is determined in Act35 that it is the highest priority accounting machine (YES in Act35), the CPU 12a is requested to send a link request command to the registration machine 11 in which it is the highest priority accounting machine as Act36. Controls the communication unit 12h. By this control, a link request command destined for the device ID of the corresponding registration machine 11 is transmitted to the LAN 13. The link request command includes its own device ID (accounting machine ID) as a transmission source. The link request command is received by the registration machine 11 in which the destination device ID is set.

After transmitting the link request command, the CPU 11a determines whether or not the permission response command has been received as Act37.
As described above, when the registration machine 11 in the standby state of Act3 and Act4 receives the link request command, the CPU 11a of the registration machine 11 executes the processes of Act7 to Act9. That is, the CPU 11a stores the device ID (accounting machine ID) of the transmission source included in the link request command in the link destination ID memory (Act7), and displays the link destination image on the touch panel 11f (Act8). Further, the CPU 11a transmits a permission response command to the accounting machine 12 which is the transmission source of the link request command (Act9). On the other hand, the registration machine 11 in the standby state of Act 11 to Act 13 does not accept the link request command. Therefore, the registration machine 11 does not send the permission response command to the accounting machine 12 which is the transmission source of the link request command.

If the permission response command cannot be received for the link request command (NO in Act37), the CPU 12a returns to the processing of Act33. Therefore, in this case, since the device status ST remains “0”, the CPU 12a repeats the processes of Act 34 to Act 37.

When the permission response command is received for the link request command (YES in Act 37), the CPU 12a stores the device ID of the registration machine 11 included as the destination in the command as Act 38 in the link destination ID memory 44. Further, the CPU 12a updates the device status ST to "1" as Act 39. After that, the CPU 12a returns to the process of Act33.

Here, the checkout system 10 constitutes a link means by processing Acts 7 to 9 of the registration machine 11 and processing Acts 34 to 39 of the accounting machine 12.

When returning to the processing of Act33 after the processing of Act39, the device status ST has been updated to "1", so that the CPU 12a executes the pre-accounting processing as Act40.

FIG. 7 is a flow chart showing a specific procedure of pre-accounting processing. When entering the pre-accounting process, the CPU 12a sets the media data M to “0” as Act51. The media data M is data that identifies the payment method of the price. In the present embodiment, the media data M for identifying cash payment is "1", the media data M for identifying electronic money payment is "2", and the media data M for identifying credit card payment is "3". “0” represents a state in which the payment method is indefinite.

The CPU 12a clears the data buffer 41 as Act 52. Then, the CPU 11a displays the accounting preparation image SC3 (see FIG. 13) on a part of the screen of the touch panel 12f as Act53.

The accounting preparation image SC3 supports a customer who prepares for payment. As shown in FIG. 13, the accounting preparation image SC3 includes display areas D3, D4, and D5. The display area D3 displays guidance and the like to customers. The display area D4 displays the registration details of the product that the customer intends to purchase.

The communicate button B2 is touched when the customer purchases a paid shopping bag. The communicate button B3 is touched when the customer wants equipment such as chopsticks or a spoon. Needless to say, the communicate buttons B1, B2, and B3 are not limited to the three types shown in FIG.

Two types of electronic money buttons B4 and B5 are displayed in the electronic money area D52. The electronic money button B4 is touched when the customer charges the electronic money. The electronic money button B5 is touched when the customer inquires about the balance of electronic money. Needless to say, the electronic money buttons B4 and B5 are not limited to the two types shown in FIG.

Three types of payment means buttons B6, B7, and B8 are displayed in the payment selection area D53. The payment means button B6 is touched when the customer selects cash payment. The payment means button B7 is touched when the customer selects electronic money payment. The payment method button B8 is touched when the customer selects credit card payment. Needless to say, the payment means buttons B6, B7, and B8 are not limited to the three types shown in FIG.

In the registration end area D54, information for notifying the customer that the registration transaction data has been received from the registration machine 11 that has received a permission response to the link request command, that is, the registration machine 11 in the linked state is displayed. As this information, for example, the message "Please pay with the payment method of your choice" may be displayed. The total points or total amount included in the registered transaction data may be displayed. The total points or total amount included in the registered transaction data may be displayed in the registration end area D54, and the above-mentioned message may be displayed in the display area D3.

After displaying the accounting preparation image SC3, the CPU 12a confirms whether or not the display data has been received from the registration machine 11 in the linked state as Act 54. When the display data is not received (NO in Act54), the CPU 12a confirms whether or not the communicate buttons B1, B2, and B3 have been input as Act55. When the communicate buttons B1, B2, and B3 are not input (NO in Act55), the CPU 12a confirms whether or not the electronic money buttons B4 and B5 are input as Act56. When the electronic money buttons B4 and B5 are not input (NO in Act56), the CPU 12a examines the media data M as Act57. Then, when the media data M is “0” (YES in Act57), the CPU 12a confirms whether or not the payment means buttons B6, B7, and B8 have been input as Act58. If the payment means buttons B6, B7, and B8 are not input (NO in Act58), the CPU 12a returns to the process of Act54. Therefore, when the media data M is "0", that is, when the payment method is undefined, the CPU 11a receives the display data, the communicate buttons B1, B2, and B3 are input, or the electronic money buttons B4 and B5 are input. It waits for the payment means buttons B6, B7, and B8 to be input.

When the display data is received in the standby state of Act 54 to Act 58 (YES in Act 54), the CPU 12a updates the registration details display in the display area D4 as Act 59. The display data includes information on the product name, unit price, number of points sold, and amount of sales registered in the data buffer 31 in the registration machine 11 in the linked state, and information on the total number of points and the total amount of money. The CPU 12a updates the registration details display in the display area D4 based on the received display data. After updating the registration details display in the display area D4, the CPU 12a returns to the standby state of Act 54 to Act 58.

Here, the checkout system 10 constitutes a display means by processing Act 16 of the registration machine 11 and processing Act 54 and Act 59 of the accounting machine 12.

When the communicate buttons B1, B2 and B3 are input in the standby state of Act54 to Act58, the CPU 12a responds to the type of the communicate buttons B1, B2 and B3 input to the registration machine 11 linked as Act60. The communication unit 12h is controlled so as to transmit the communicate command. By this control, a communicate command addressed to the device ID stored in the link destination ID memory 44 is transmitted to the LAN 13. This communicate command is received by the registration machine 11 identified by the destination device ID. As described above, in the registration machine 11 that has received the communicate command, a message, an icon, or the like corresponding to the command is displayed on the touch panel 11f.

For example, when a communicate command corresponding to the communicate button B1 is received, the registration machine 11 displays a message, an icon, or the like informing the clerk 21 that the customer 22 will use the gift certificate on the touch panel 11f. The clerk 21 who has confirmed this notification may go to the customer 22 to receive the gift certificate and register the face value of the gift certificate in the accounting machine 12 or the registration machine 11.

When a communicate command corresponding to the communicate button B2 is received, the registration machine 11 displays a message, an icon, or the like informing the clerk 21 that the customer 22 will use the pay plastic shopping bag on the touch panel 11f. After confirming this notification, the clerk 21 may register the paid shopping bag in the registration machine 11 and put the shopping bag in the shopping cart 16 containing the product to be purchased.

Further, when a communicate command corresponding to the communicate button B3 is received, the registration machine 11 displays a message, an icon, etc. on the touch panel 11f informing the clerk 21 that the customer 22 requests equipment such as chopsticks or spoons. Is displayed. The clerk 21 who confirms this notification may hand over the necessary equipment from the product to be purchased to the customer 22.
After controlling the transmission of the communicate command, the CPU 12a returns to the standby state of Act 54 to Act 58.

Here, the checkout system 10 constitutes a notification receiving means by processing Act55 and Act60 of the accounting machine 12.

When the electronic money buttons B4 and B5 are input in the standby state of Act54 to Act58, the CPU 12a executes the electronic money processing as Act61.
FIG. 8 is a flow chart showing a specific procedure of electronic money processing. When the electronic money processing is started, the CPU 12a confirms which of the electronic money buttons B4 and B5 is input as Act71. When the electronic money button B4 is input (“charged” in Act71), the CPU 12a detects the balance of electronic money from the data of the electronic money medium read by the electronic money reader / writer 12k as Act72, and touch panel 12f. Display on. At this time, the touch panel 12f displays the balance of the electronic money and the end button for the customer 22 to command the end of charging.

The CPU 12a confirms whether or not the end button has been input as Act 73. When the end button is not input, the CPU 12a confirms whether or not the charge amount has been deposited in the automatic change machine 12m as Act 74. If the charge amount has not been deposited, the CPU 12a returns to Act 73. Therefore, in the processing of Act73 and Act74, the CPU 12a waits for the end button to be input or the charge amount to be deposited.

When the charge amount is deposited in the standby state of Act73 and Act74, the CPU 12a updates the balance of the electronic money medium as Act75 so as to be increased by the deposit amount. Further, the CPU 12a displays the updated balance on the touch panel 12f. After that, the CPU 12a returns to the standby state of Act73 and Act74.

When the end button is input in the standby state of Act73 and Act74, the CPU 12a issues a new accounting machine transaction number as Act76. The accounting machine transaction number is, for example, a number that increases by 1 in order from 1. When the accounting machine transaction number is issued, the CPU 12a controls the printer 12g so as to issue a charge receipt as Act 77. By this control, a charge receipt is issued on which the balance before charging, the amount charged, the balance after charging, the accounting machine transaction number, and the like are printed.

After controlling the issuance of the charge receipt, the CPU 12a erases the balance displayed on the touch panel 12f as Act78. This completes the electronic money processing when the electronic money button B4 is input.
Here, the checkout system 10 constitutes a charge receiving means by processing Act56 and Act61 (Act71 to Act77) of the accounting machine 12.

On the other hand, when the electronic money button B5 is input (“inquiry” in Act71), the CPU 12a detects the balance of electronic money from the data of the electronic money medium read by the electronic money reader / writer 12k as Act79. Then, it is displayed on the touch panel 12f. At this time, the touch panel 12f displays a confirmation button for instructing the customer 22 to confirm the confirmation along with the balance of the electronic money.

The CPU 12a waits for the confirmation button to be input as Act 80. If the confirmation button is input (YES in Act80), the CPU 12a erases the balance displayed on the touch panel 12f as Act78. This completes the electronic money processing when the electronic money button B5 is input. When the electronic money processing is completed, the CPU 12a returns to the standby state of Act 54 to Act 58.

When the payment means buttons B6, B7, and B8 are input in the standby state of Act54 to Act58 (YES in Act58), the CPU 12a changes the media data M as Act62. That is, when the payment means button B6 is input, the CPU 12a changes the media data M to "1", and when the payment means button B7 is input, the CPU 12a changes the media data M to "2". When the payment means button B8 is input, the CPU 12a changes the media data M to “3”. After that, the CPU 12a executes the payment acceptance process as Act63.

FIG. 9 is a flow chart showing a specific procedure of payment acceptance processing. Upon entering the payment acceptance process, the CPU 12a examines the media data M as Act91.
When the media data M is "1", the CPU 12a confirms the presence or absence of payment as Act92. If no cash has been inserted into the automatic change machine 12m (NO in Act92), the CPU 12a ends the payment acceptance process. When cash is inserted into the automatic change machine 12m (YES in Act92), the CPU 12a stores the deposit amount in the data buffer 41 as Act93, and displays a message indicating that cash payment has been selected on the touch panel 12f. Display on. With the above, the CPU 12a ends the payment acceptance process.

When the media data M is "2", the CPU 12a confirms whether or not the data of the electronic money medium is read by the electronic money reader / writer 12k as Act94. When the data in the electronic money medium is not read (NO in Act94), the CPU 12a ends the payment acceptance process. When the data of the electronic money medium is read (YES in Act94), the CPU 12a detects the balance of the electronic money from the data of the electronic money medium read by the electronic money reader / writer 12k as Act95. Then, the CPU 12a stores the balance in the data buffer 41 and displays a message indicating that the electronic money payment has been selected on the touch panel 12f. With the above, the CPU 12a ends the payment acceptance process.

When the media data M is “3”, the CPU 12a confirms whether or not the card reader / writer 12j is reading the credit card data as Act 96. If the credit card data has not been read (NO in Act96), the CPU 12a ends the payment acceptance process. If the credit card data is being read (YES in Act96), the CPU 12a stores the credit card data read by the card reader / writer 12j as Act97 in the data buffer 41, and credit card payment is selected. A message indicating that the data has been sent is displayed on the touch panel 12f. With the above, the CPU 12a ends the payment acceptance process.
Here, the checkout system 10 constitutes a payment receiving means by processing Act58 and Act62 to Act63 (Act91 to Act97) of the accounting machine 12.

When the payment acceptance process is completed, the CPU 12a returns to the process of Act 54. Therefore, since the media data M is not "0" this time (NO in Act57), the CPU 12a proceeds to NO in Act57. That is, the CPU 12a waits for the display data to be received, the communicate buttons B1, B2, and B3 to be input, or the electronic money buttons B4 and B5 to be input. Further, the CPU 12a executes the payment acceptance process.

The explanation is returned to FIG. While executing the pre-accounting process, the CPU 12a waits for the registration transaction data transmitted from the registration machine 11 as Act 41. When the registered transaction data is received (YES in Act41), the CPU 12a updates the device status ST to "2" as Act42. After that, the CPU 12a returns to the process of Act33. Therefore, in this case, since the device status ST has been updated to "2", the CPU 12a stores the registered transaction data in the transaction buffer 42 as Act43.

After storing the registered transaction data in the transaction buffer 42, the CPU 12a executes accounting processing as Act44.

FIG. 10 is a flow chart showing a specific procedure of accounting processing. When the accounting process is started, the CPU 12a displays information as Act101 in the registration end area D54 of the accounting preparation image SC3 to notify the customer that the registration transaction data has been received as described above.

Next, the CPU 12a examines the media data M as Act 102. When the media data M is "0" (YES in Act 102), the payment method is undefined. In this case, the CPU 12a waits for the payment means buttons B6, B7, and B8 to be input as Act103. If the payment means buttons B6, B7, and B8 are input (YES in Act102), the CPU 12a changes the media data M as Act104. That is, when the payment means button B6 is input, the CPU 12a changes the media data M to "1", and when the payment means button B7 is input, the CPU 12a changes the media data M to "2". When the payment means button B8 is input, the CPU 12a changes the media data M to “3”. Therefore, it is possible for the customer 22 to select the payment method not only before the accounting machine 12 receives the registered transaction data but also after receiving the registered transaction data.

If the media data M is changed in Act 104, or if the media data M is not already "0" in Act 102 (NO in Act 102), the CPU 12a issues a new accounting machine transaction number as Act 105. When the accounting machine transaction number is issued, the CPU 12a edits the transaction data as Act106. Specifically, the CPU 12a adds the payment transaction data stored in the data buffer 41 together with the accounting machine transaction number to the registered transaction data stored in the transaction buffer 42 to generate transaction data representing the content of one transaction.

Next, the CPU 12a examines the media data M as Act107. Here, when the media data M is "1", the CPU 12a executes the cash settlement process as Act108. That is, when the deposit amount put into the automatic change machine 12m becomes equal to or more than the total amount, the CPU 12a calculates the change amount. At this time, if the deposit amount is stored in the payment acceptance process, the deposit amount becomes the deposit amount. When more cash is inserted into the automatic change machine 12 m, the inserted amount is added to the deposit amount to become the deposit amount. Therefore, the customer can take measures such as inserting banknotes for an approximate price at the stage of pre-accounting processing and inserting coins for a fraction of the price determined at the stage of accounting processing.

When the cash settlement process is completed, the CPU 12a updates the transaction data in the transaction buffer 42 as Act109. Specifically, the CPU 12a adds the deposit amount and the change amount to the transaction data. Then, the CPU 12a creates print data of the purchase receipt as Act110 based on the data of the transaction buffer 42, outputs the print data to the printer 12g, and controls the issuance of the purchase receipt.

In Act107, when the media data M is "2", the CPU 12a executes the electronic money payment process as Act111. That is, the CPU 12a subtracts the total amount from the balance of electronic money obtained from the data read from the electronic money medium by the electronic money reader / writer 12k. At this time, if the electronic money balance is already stored in the payment acceptance process, the electronic money balance is used.

When the electronic commerce payment process is completed, the CPU 12a updates the transaction data in the transaction buffer 42 as Act112. Specifically, the balance of electronic money before payment and the balance of electronic money after payment are added to the transaction data. Then, the CPU 12a creates print data of the purchase receipt as Act 113 based on the data of the transaction buffer 42, outputs the print data to the printer 12g, and controls the issuance of the purchase receipt.

In Act107, when the media data M is "3", the CPU 12a executes the credit card payment process as Act114. That is, the CPU 12a authenticates the data read from the credit card by the card reader / writer 12j. At this time, if the credit card data is stored in the payment acceptance process, the data is authenticated.

When the credit card data is authenticated and the credit card payment process is completed, the CPU 12a updates the transaction data in the transaction buffer 42 as Act 115. Specifically, the payment amount by credit card, some information of the credit card, etc. are added to the transaction data. Then, the CPU 12a creates print data of the credit slip based on the data of the transaction buffer 42 as Act116, outputs the print data to the printer 12g, and controls the issuance of the credit slip.

In this way, when the purchase receipt is issued (Act110, Act113) or the credit slip is issued (Act116), the CPU 12a stores the transaction data in the transaction buffer 42 as Act117 in the auxiliary storage unit 12d. With the above, the CPU 12a ends the accounting process.
Here, the checkout system 10 constitutes a settlement means by processing Act13, Act18 to Act21 of the registration machine 11 and processing of Act41, Act43 to Act44 of the accounting machine 12.

The explanation is returned to FIG. When the accounting process is completed, the CPU 12a clears the device ID stored in the link destination ID memory 32 as Act 45.

Here, the checkout system 10 constitutes a cancellation means by processing Act 23 of the registration machine 11 and processing Act 45 of the accounting machine 12.

When the processing of Act45 is completed, the CPU 12a ends the information processing for one transaction. Then, the CPU 12a starts the process again from Act 31.

Next, the operation and effect of the checkout system 10 will be described by taking a checkout lane in which the registration machine 11 of the device ID “R1” (hereinafter referred to as registration machine 11-R1) is installed as an example.
In FIG. 1, it is assumed that the registration work of the product to be purchased by the customer 22 at the installation location of the accounting machine 12 (hereinafter referred to as the accounting machine 12-A2) of the device ID "A2" is completed by the registration machine 11-R1. Then, the device status ST of the accounting machine 12-A2 becomes “2”. On the other hand, it is assumed that the accounting machine 12 (hereinafter referred to as accounting machine 12-A1) of the device ID "A1" is in the idle state. In this case, the accounting machine 12-A1 is the highest priority accounting machine for the registration machine 11-R1. Therefore, the link request command is transmitted from the accounting machine 12-A1 to the registration machine 11-R1. Then, when the registration machine 11-R1 and the accounting machine 12-A1 are in a linked state, the link destination image SC2 that guides the customer 22 to the accounting machine 12-A1 is displayed on the touch panel 11f of the registration machine 11-R1. .. Further, the accounting preparation image SC3 is displayed on the touch panel 12f of the accounting machine 12-A1.

Here, when the next customer 22 arrives at the checkout lane, the clerk 21 guides the customer 22 to guide the customer 22 to the accounting machine 12-A1 represented by the linked image SC2. The guidance method is not particularly limited. Generally, it is conceivable to verbally inform you, "Please move to the A1 accounting machine and prepare for payment." The customer 22 who hears the guidance moves to the installation location of the accounting machine 12-A1.

The clerk 21 who is the operator of the registration machine 11-R1 starts data input of the product to be purchased by the customer 22 who has moved to the installation location of the accounting machine 12-A1. Then, in the registration machine 11-R1, the data of the product to be purchased is stored in the data buffer 31. Further, in the accounting machine 12-A1, the data stored in the data buffer 31, that is, the details of the product to be purchased (product name, unit price, number of items sold, and sales amount) are displayed in the display area D4 of the accounting preparation image SC3. NS. Therefore, the customer 22 who has moved to the installation location of the accounting machine 12-A1 can confirm the registered contents in the registration machine 11-R1 in real time from the contents of the display area D4. In this way, it can be confirmed that the product to be purchased is correctly registered by the clerk 21 even if he / she leaves the clerk 21, so that the customer 22 can move to the installation location of the accounting machine 12-A1 with confidence. can.

Can be notified. Similarly, by touching the communicate button B2, the use of a paid plastic shopping bag can be notified, and by touching the communicate button B3, a request for equipment such as chopsticks or a spoon can be notified. In this way, even if the customer 22 moves to the installation location of the accounting machine 12-A1, the customer 22 can communicate with the clerk 21 who operates the registration machine 11-R1). Therefore, the customer 22 can safely move to the installation location of the accounting machine 12 according to the instruction of the clerk 21 even before the data input of the product to be purchased is completed.

In addition, the customer 22 who confirmed the accounting preparation image SC3 touches the electronic money button B4, holds the electronic money medium on the electronic money reader / writer 12k, and puts the charge amount into the automatic change machine 12m. Can be charged. Similarly, by touching the electronic money button B5 and holding the electronic money medium over the electronic money reader / writer 12k, the customer 22 can inquire about the balance of the electronic money. In this way, while the accounting preparation image SC3 is displayed, that is, while the data of the product to be purchased is being input by the registration machine 11-R1, the customer 22 operates the accounting machine 12-A1 and electronically. You can charge money or check the balance.

Similarly, the customer 22 who has confirmed the accounting preparation image SC3 can proceed with the preparation for cash payment by touching the payment means button B6. Specifically, the cash required for payment can be input to the automatic change machine 12 m in advance.
