Description

The present invention relates to a merchandise sales data processing system, a registration device, and a program.

BACKGROUND ART A POS (Point Of Sales) system is known that includes a registration device that registers products and a settlement device that settles accounts for the products registered by the registration device.
Also, among the POS systems described above, there is known a system capable of a process called call-back. As an example, recall is performed as follows. After the registration data is output from the registration device to the settlement device for a certain transaction, the customer may request a change in the registered content, such as the addition of merchandise. In such a case, the store clerk who operates the registration device performs a recall operation for instructing the registration device to recall the registration data corresponding to the transaction.

In response to the recall operation, the settlement process based on the registration data corresponding to the relevant transaction in the settlement device is temporarily canceled, and the registration data corresponding to the relevant transaction is recalled from the settlement device to the registration device. By recalling the registered data to the registration device in this way, the store clerk can make corrections, such as additional registration of the product or cancellation of the product, with respect to the recalled registration data.

The recall operation described above is performed, for example, as follows. A store clerk who operates the registration device first displays an unsettled list screen showing a list of unsettled transactions among the transactions corresponding to the registration data output to the settlement device. The store clerk selects the transaction corresponding to the registered data to be recalled from the list of transactions displayed on the displayed unsettled list screen, and then performs an operation (for example, pressing a button) to instruct recall execution. operation). Registration data corresponding to the selected transaction is output to the registration device so as to be returned from the settlement device in response to an operation instructing execution of recall (see, for example, Patent Document 1).

JP 2016-91185 A

Currently, even if the settlement device is in the process of settlement processing using one registration data, there is no particular limit on the number of registration data that the settlement device can accept for subsequent settlement processing, or settlement There is a POS system in which the upper limit of the number of registration data that can be accepted by the device is relaxed and set relatively large. In such a POS system, the number of unsettled registration data transmitted from the registration device to the settlement device is considerably large. In such a case, the recall operation as described above is effective because the transaction to be corrected can be easily identified from among the large number of unsettled transactions displayed on the unsettled list screen.

However, from the experience of operating the POS system, it has been recognized that, for example, if the number of registration data that can be accepted by the settlement device from the registration device is limited, the accounting will be performed smoothly. . For this reason, at present, there is a tendency to reduce the number of registration data that the settlement device can receive from the registration device, for example, to one.
In general, one registration device corresponds to at most three settlement devices. In this case, if the upper limit of the number of registration data that the settlement device can receive from the registration device is one, the maximum number of unprocessed registration data on the settlement device side corresponding to one registration device is also three. Become. If the number of unprocessed registration data is so small, the store clerk can remember which settlement device has output the registration data of which transaction.
Considering the above, the recall operation of displaying the unsettled list screen and selecting the transaction to be corrected is a POS system that limits the number of registration data that the settlement device can accept from the registration device. Then, a wasteful procedure is generated.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and is directed to efficiently recall registered data from the settlement device to the registration device in a merchandise sales data processing system comprising a registration device and a settlement device. intended to

That is. The recall is generally performed in response to, for example, canceling the product registered by the registration device 20 or additionally registering the product for additional purchase.

A recall operation performed by a store clerk for recalling registered data in this embodiment will be described below.
FIG. 5 shows an example of a product registration screen displayed on the store clerk display unit 205 of the registration device 20. As shown in FIG. Note that the fare adjustment machine list button BT2 and the previous recall button BT3 shown in FIG. do.
The product registration screen shown in the figure has a structure in which sheets (product registration sheets) indicating the content of product registration corresponding to each transaction are superimposed. Each product registration sheet is provided with a tab (product registration tab: an example of a header area). In the figure, three product registration tabs TAB1-1, TAB1-2 and TAB1-3 are displayed. The product registration screen shown in the figure has a structure in which these three product registration sheets are superimposed.
The product registration tabs TAB1-1, TAB1-2, and TAB1-3 display numbers indicating registration order numbers. The registration order number indicates the order in which product registration was started. In the figure, registration order numbers "1", "2" and "3" are displayed on the product registration tabs TAB1-1, TAB1-2 and TAB1-3, respectively. This means that the order in which product registration was started is the order of the transaction corresponding to the product registration tab TAB1-1, the transaction corresponding to the product registration tab TAB1-2, and the transaction corresponding to the product registration tab TAB1-3. indicates
In the following description, the individual product registration tabs TAB1-1, TAB1-2, TAB1-3, etc. will be referred to as product registration tab TAB1 unless otherwise distinguished.

In this embodiment, the fact that three product registration tabs TAB1 are displayed as shown in FIG. is shown. The store clerk can perform the product registration for the corresponding transaction by operating the product registration sheet arranged in the foreground among these three product registration sheets. As for the transaction corresponding to the product registration sheet arranged below the forefront, the product registration is suspended.
By performing an operation (touch operation) on the product registration tab TAB1, the clerk moves the product registration sheet to which the operated product registration tab TAB1 is attached to the foreground, and corresponds to the product registration sheet moved to the forefront. It is possible to register products for transactions to be made. In other words, the store clerk selects the active product registration sheet corresponding to any one transaction from among the multiple transactions being registered by operating the product registration tab TAB1, and selects the active product registration sheet. Product registration operations in transactions can be performed.

The figure shows a state in which the product registration sheet with the product registration tab TAB1-1 is activated. A product button area AR10 is arranged in the active product registration sheet. In the product button area AR10, product buttons corresponding to each product are arranged. The product button displays, for example, the product name indicating the corresponding product.
The store clerk can specify the product to be registered by operating the product button in the product registration operation. Specifically, when a product with a product name of "product B" is to be designated as a registration target, the clerk operates the product button labeled "product B" among the product buttons arranged in the product button area AR10. should be done. By operating the product button for "product B", "product B" is designated as a registration target. Subsequently, the store clerk can perform an operation of inputting, for example, the quantity of "merchandise B". By performing the above-described operation for each purchased product, the store clerk can register the products one by one.

The product registration sheet of FIG. 1 shows that two products are currently registered. Specifically, in the registered product list area AR11 in the product registration sheet of FIG. 10, it is indicated that two products have been registered in the order of "product A" and "product B". Further, in the registered product area AR12, information about the last registered "product B" is shown. The total amount area AR13 indicates that the total number of products registered so far is "2" and the total amount of these two products is 1900 yen.

Also, on the product registration screen, checkout device designation buttons BT1-1 and BT1-2 are arranged. The settlement device designation buttons BT1-1 and BT1-2 correspond to the settlement devices 30-1 and 30-2, respectively, and are buttons for performing an operation of designating the settlement device 30 that executes settlement processing (settlement device designation operation). is.
Note that the settlement device designation buttons BT1-1 and BT1-2 are referred to as the settlement device designation button BT1 when they are not distinguished from each other.

The current state of the corresponding settlement device 30 is indicated by the settlement device designation button BT1. In the figure, a badge indicating "standby" is arranged on the settlement device designation button BT1-1. The state of the settlement device designation button BT1-1 indicates that the settlement device 30-1 is waiting for the start of settlement processing. In other words, the settlement device 30-1 at this time does not store unprocessed registration data, and is in a state of waiting for new registration data to be received.
In addition, a badge indicating "in use" is placed on the fare adjustment device designation button BT1-2, and a lane is drawn for the characters "payment machine 2" on the fare adjustment device designation button BT1-2. state. The state of the settlement device designation button BT1-2 indicates that the settlement device 30-2 has not completed the settlement processing based on the acquired registration data (an example of the in-use state). The state in which settlement processing has not been completed means that the settlement processing has started with the acquired registration data as the processing target, but the settlement processing has not been completed yet, or the registration data has been acquired from the registration device 20, but the acquired registration data has not yet been completed. This is a state in which the settlement process for which the data is to be processed has not started.
For example, the color and pattern of the settlement device designation button BT1 itself may be changed according to the state of the settlement device 30 as described above.

For example, when the operation of registering all the products for the transaction corresponding to the product registration sheet with the product registration tab TAB1-1 shown in FIG. The settlement device 30 to be executed is selected. At this time, the clerk can understand that the settlement device 30-1 is on standby and the settlement device 30-2 is in use by looking at the settlement device designation button BT1.

In this embodiment, the case where the upper limit number of registration data that can be accepted by the settlement device 30 is "1" will be taken as an example. Therefore, even if registration data is newly transmitted from the registration device 20 while the settlement device 30 is executing settlement processing based on one piece of registration data received from the registration device 20, the settlement device 30 does not transmit the registration data. The received registration data is not accepted as a processing target.

In this case, since the settlement device 30-1 is in use, the registration data cannot be sent to the settlement device 30-1. On the other hand, the settlement device 30-2 is in a standby state. In the standby state, settlement device 30-2 can accept the transmitted registration data. Therefore, the store clerk in this case selects the settlement device 30-2 as the settlement device 30 to execute settlement processing. Then, the store clerk operates the settlement device designation button BT1-2 corresponding to the settlement device 30-2 as the settlement device designation operation.

In response to the operation of the settlement device designation button BT1-2 as the settlement device designation operation, the registration device 20 registers the registration data of the transaction corresponding to the product registration sheet to which the product registration tab TAB1-1 is attached. It is transmitted to the settlement device 30-2 to instruct settlement processing.
In response to the transmission of the registration data to the settlement device 30-2 as described above, the product registration sheet with the product registration tab TAB1-1 that has been displayed on the registration device 20 is changed to the product registration sheet. It should be erased from the screen. Then, instead, for example, the product registration sheet with the product registration tab TAB1-2 is displayed so as to be in the foreground.
Also, when the product registration sheet with the product registration tab TAB1-2 is displayed in the foreground, the registration order number displayed on the product registration tab TAB1-2 changes from "2" to " 1”, and the registration order number displayed on the product registration tab TAB1-2 is moved up from “3” to “2”.

The recall operation in this embodiment includes the operation on the settlement device designation button BT1 arranged on the product registration screen. That is, the settlement device designation button BT1 in the present embodiment performs an operation of selecting the settlement device 30 to which the registration data to be recalled is sent, in addition to the operation of designating the settlement device 30 that executes the settlement process described above.

A specific example of the recall operation under the state of the product registration screen shown in the figure is as follows.
Under the condition of the product registration screen shown in FIG. )It is in. Then, the store clerk receives a request for additional registration of merchandise or partial cancellation of the registered merchandise from a customer of the transaction corresponding to the registration data currently being processed by the settlement device 30-2.
In order to correct the corresponding registration data, the store clerk who receives the above request operates the settlement device designation button BT1-2 corresponding to the settlement device 30-2, which is the transmission destination of the registration data.
Here, the settlement device designation button BT1-2 in the figure is shown to be in the "in use" state. In the present embodiment, the operation on the settlement device designation button BT1 in the "in use" state is one operation included in the recall operation, and the operation of selecting the settlement device 30 to which the registered data to be recalled is to be output. (Recall target selection operation). In the example of FIG. 1, the settlement device designation button BT1-1 indicates "standby" (waiting), and the settlement device designation button BT1-2 indicates "in use". Therefore, as the recall target selection operation, only the settlement device designation button BT1-2 is available as an option. However, for example, when both the settlement device designation buttons BT1-1 and BT1-2 indicate "in use", both the settlement device designation buttons BT1-1 and BT1-2 are called back target selection operations. be an option.

In response to the recall target selection operation performed on the settlement device designation button BT1-2 as described above, a recall confirmation dialog box is displayed so as to be superimposed on the product registration screen.
The call-back confirmation dialog box is a dialog box for asking the clerk whether or not to execute the call-back process. Although illustration is omitted, in the recall confirmation dialog box, a message is displayed prompting the clerk to confirm whether or not it is permissible to recall the registered data from the settlement device 30 selected by the clerk through the recall target selection operation. .
Also, in the recall confirmation dialog box, for example, a "yes" button and a "no" button are arranged. The "yes" button is a button operated by the store clerk when instructing to recall the registered data. The "No" button is a button operated by the store clerk when canceling the recall of registered data.

If the clerk determines that the fare adjustment device 30 selected by the recall target selection operation is correct and that the recall can be performed under the condition that the recall confirmation dialog box is displayed, the clerk operates the "Yes" button. (Recall instruction operation).
The registration device 20 executes the recall process in response to the recall instruction operation described above. That is, the registration device 20 in this case transmits a return request for the registered data to the settlement device 30-2 corresponding to the settlement device designation button BT1-2 on which the recall target selection operation has been performed. In response to receiving the return request, the settlement device 30-2 transmits the unprocessed registration data to the registration device 20 that sent the return request. The settlement device 30-2 deletes the registration data transmitted in response to the return request, or excludes it from settlement processing. Recall is performed when the registration data transmitted from the settlement device 30 to be returned is received by the registration device 20 .

The registration device 20 that has acquired the registration data recalled from the settlement device 30 as described above uses the recalled registration data to display the transaction correction screen. The store clerk can make corrections such as additional registration of products and partial cancellation of products by operating the transaction correction screen. When the correction is completed, the registration device 20 transmits the registration data reflecting the corrected content to the settlement device 30 that transmitted the recalled registration data. The settlement device 30 starts settlement processing based on the newly received registration data.
Here, the transmission of the registration data to the settlement device 30 may be automatically performed by the registration device 20, or may be performed in response to the transmission instruction operation of the store clerk. Also, the settlement device 30 of the transmission destination may be the settlement device 30 that is the source of the recalled registration data, or may be registered according to the instruction operation of the settlement device by the clerk, the state of the settlement device 30, or the like. Device 20 may determine.

On the other hand, if the clerk erroneously performs a recall target selection operation (an operation on the "in use" settlement device designation button BT1), or a recall confirmation dialog box is displayed. At some stage, if the customer withdraws the offer to correct the transaction, the store clerk can operate the "No" button in the recall confirmation dialog box.
In response to the operation of the "No" button, the registration device 20 erases the recall confirmation dialog box and restores the state of the product registration screen before the recall confirmation dialog box was displayed.

In the recall operation as described above, the store clerk can specify the settlement device 30 to which the registration data is to be recalled by operating the settlement device designation button BT1 indicating the "in use" state. That is, in the recall operation of the present embodiment, the recall of registered data can be declared and the registered data to be recalled can be specified by operating the settlement device specifying button BT1 indicating the "in use" state.
As a result, the store clerk, as a recall operation, displays an unsettled list screen showing a list of transactions corresponding to unprocessed registered data, and selects a transaction to be corrected from the displayed unsettled list screen. You do not have to perform the operation. That is, in the present embodiment, the operation procedure performed by the store clerk as the recall operation is simplified, and the recall operation is performed efficiently.

An example of a processing procedure executed by the registration device 20 in this embodiment in relation to recall will be described with reference to the flowchart of FIG. 6 .
Step S101: With the product registration screen displayed, the registration device 20 waits for an operation on the settlement device designation button BT1 indicating the "in use" state. That is, the registration device 20 waits for the recall target selection operation to be performed.
Step S102: In response to the recall target selection operation being performed, the registration device 20 controls the store clerk display section 205 to display a recall confirmation dialog box superimposed on the product registration screen.
Step S103: While the recall confirmation dialog box is being displayed, the registration device 20 determines whether or not the "Yes" button arranged in the recall confirmation dialog box has been operated, that is, the recall instruction operation has been performed. to determine.

Step S104: When the recall instruction operation is performed, the registration device 20 performs recall processing of the registered data.
That is, the registration device 20 transmits a registration data return request to the settlement device 30 selected by the recall target selection operation in step S101, and returns the registration data transmitted from the settlement device 30 in response to the return request. receive.
Step S105: The registration device 20 that has acquired the registration data through the recall process in step S104 clears the recall confirmation dialog box displayed in step S102.
Step S106: Further, the registration device 20 uses the recalled registration data to display the transaction correction screen. After displaying the transaction correction screen, the registration device 20 recalls the registration recalled in response to the operation for correcting the transaction (additional registration of the product, partial cancellation of the product, etc.) performed on the transaction correction screen. It is possible to change the contents of the data, transmit the changed registration data to the settlement device 30, and instruct the settlement processing.

Step S107: On the other hand, if the "No" button arranged in the recall confirmation dialog box is operated to cancel the recall declaration, the registration device 20 does not perform the recall instruction operation in step S103. I judge that. In this case, the registration device 20 erases the recall confirmation dialog box displayed in step S102, and returns the display on the store clerk display unit 205 to the product registration screen with the contents before the recall confirmation dialog box was displayed. .

<Second embodiment>
Next, a second embodiment will be described. An example of recall operation in the present embodiment will be described with reference to FIG. This figure shows an extracted portion of the product registration screen of the present embodiment where the product registration tab TAB1 is displayed. It should be noted that portions other than those shown in FIG. 5 may be the same as those shown in FIG. 5 in the product registration screen of the present embodiment.

In the registration device 20 of the present embodiment, an operation for registering a product corresponding to one transaction and an adjustment device designation operation (adjustment device designation indicating a "standby" state) performed in response to the completion of product registration in one transaction The operation on the button BT1) may be the same as in the first embodiment.
In addition, in the present embodiment, in response to the operation for specifying a settlement device, a settlement tab (an example of a header area) indicating that the settlement device 30 designated by the settlement device designation operation is in use is displayed. is displayed on the product registration screen.

FIG. 7 shows one mode example of the display of the settlement tab. The figure shows a state in which one product registration tab TAB1-1 and two checkout tabs TAB2-1 and TAB2-2 are displayed.
The product registration tab TAB1-1 is attached to the product registration sheet corresponding to the transaction being registered in the registration device 20, as described in the first embodiment. In the example shown in the figure, the product registration sheet to which the product registration tab TAB1-1 is attached is displayed in the foreground by selecting the product registration tab TAB1-1.
For example, from the state shown in the figure, when the product registration of the transaction corresponding to the product registration tab TAB1-1 is suspended and an operation of registering the product of another transaction is performed, the product registration tab TAB1 shown in the figure is displayed. -1, In addition to the checkout tabs TAB2-1 and TAB2-2, a product registration tab TAB1 corresponding to another transaction is displayed.

The settlement tab TAB2-1 indicates that the settlement device 30-1 is in use by displaying the guide display GD with "settlement machine 1" indicating the settlement device 30-1. Further, the settlement tab TAB2-2 indicates that the settlement device 30-2 is in use by displaying the guide display GD with "settlement machine 2" indicating the settlement device 30-2. That is, in the example of FIG. 1, both the settlement devices 30-1 and 30-2 are currently in use.
It should be noted that, in the following description, the individual checkout tabs TAB2-1, TAB2-2, etc. will be referred to as checkout tab TAB2 unless otherwise distinguished.

The settlement tab TAB2 displayed as described above is deleted when the settlement processing in the corresponding settlement device 30 is completed.

In this embodiment, in the recall operation for recalling the registered data, the store clerk first operates the checkout tab TAB2 corresponding to the checkout device 30 to which the recalled registered data is sent. Specifically, in the case of the example shown in the figure, when the store clerk wants to recall the registered data from the settlement device 30-1, he/she operates the settlement tab TAB2-1 corresponding to the settlement device 30-1. Further, when the store clerk wants to call back the registration data from the settlement device 30-2, the clerk operates the settlement tab TAB2-2 corresponding to the settlement device 30-2.
That is, in the present embodiment, recall target selection operations (declaration of recall of registered data and designation of registered data to be recalled) are performed by operating the checkout tab TAB2.

In response to the operation on the checkout tab TAB2, the store clerk display unit 205 displays a call-back confirmation dialog box so as to be superimposed on the product registration screen. The display mode of the recall confirmation dialog box may be the same as in the first embodiment. Therefore, in the recall confirmation dialog box of the present embodiment as well, a confirmation message is displayed, and a "yes" button and a "no" button are arranged.
If the store clerk can recall the registered data as it is, the clerk performs an operation (recall instruction operation) on the "Yes" button. In response to the recall instruction operation being performed, the registration device 20 executes recall processing, uses the recalled registration data to display the transaction correction screen, and corrects the transaction, as in the first embodiment. corresponds to
On the other hand, if the store clerk wants to cancel the recall of the registered data, he/she operates the "No" button. The registration device 20 erases the recall confirmation dialog box and restores the state of the product registration screen before the recall confirmation dialog box was displayed.

Even with such a recall operation, as in the first embodiment, the store clerk performs an operation to display an unsettled list screen showing a list of transactions corresponding to unprocessed registration data, and an unsettled transaction displayed on the screen. It is not necessary to perform the operation of selecting the transaction to be corrected from the list screen. This simplifies the operation procedure performed by the store clerk as the recall operation, and the recall operation is performed efficiently.

According to the above description, in the present embodiment, there is no particular need to move the sheet with the checkout tab TAB2 to the forefront on the product registration screen and display it. Therefore, the sheet with the checkout tab TAB2 may not contain significant information such as the product registration sheet. Specifically, for the checkout tab TAB2, for example, a sheet with only a background may be attached. Alternatively, it may be displayed such that only the checkout tab TAB2 is arranged, and no sheet is attached to the checkout tab TAB2.

Alternatively, as a modification of the present embodiment, the sheet with the settlement tab TAB2 displays a transaction correction screen based on the recalled registration data in response to the recall of the registration data from the corresponding settlement device 30. may be displayed.
In this case, following the operation on the payment tab TAB2 (operation to select a recall target), the following display is performed in response to the operation on the "Yes" button in the recall confirmation dialog box (operation to instruct recall). You should do it like this. That is, the sheet to which the settlement tab TAB2 is attached is moved to the forefront, and the transaction correction screen based on the recalled registration data is displayed on the foremost sheet.

An example of a processing procedure executed by the registration device 20 of the present embodiment in relation to display of the checkout tab will be described with reference to the flowchart of FIG. 8 .
First, an example of a processing procedure executed by the registration device 20 in relation to starting the display of the checkout tab TAB2 will be described.
Step S201: The registration device 20 waits for a settlement device designation operation (an operation on the settlement device designation button BT1 indicating "standby") to be performed.
Step S202: In response to the completion of the registration of the product corresponding to one transaction and the clerk's operation to designate the settlement device, the registration device 20 registers the settlement device 30 designated by the settlement device designation operation. In response, registration data corresponding to one transaction for which product registration has been completed is transmitted.
Step S203: Further, the registration device 20 displays on the product registration screen a settlement tab TAB2 indicating that the settlement device 30 to which the registration data is transmitted in step S202 is "in use".

Next, an example of a processing procedure executed by the registration device 20 in relation to erasing the displayed checkout tab TAB2 will be described with reference to FIG.
Step S301: The registration device 20 waits for the settlement device 30 to complete settlement processing corresponding to one transaction. The settlement device 30 transmits a notification to that effect (a settlement processing completion notification) to the registration device 20 each time settlement processing corresponding to one transaction is completed. When receiving the settlement process completion notice, the registration device 20 can determine that the settlement process has been completed in the settlement device 30 to which the received settlement process completion notice was transmitted.
Step S302: When the registration device 20 determines that the settlement process has been completed on the settlement device 30, it deletes the settlement tab TAB2 corresponding to the settlement device 30 for which the settlement processing has been completed from the product registration screen.

Next, an example of a processing procedure executed by the registration device 20 in relation to recalling registration data will be described with reference to the flowchart of FIG. 9 .
Step S401: The registration device 20 waits for an operation on any of the checkout tabs TAB2 displayed on the product registration screen, that is, an operation to select a recall target.
Step S402: In response to the recall target selection operation being performed, the registration device 20 performs control so that a recall confirmation dialog box is superimposed and displayed on the product registration screen.
Step S403: While the recall confirmation dialog box is being displayed, the registration device 20 determines whether an operation (recall instruction operation) has been performed on the "Yes" button arranged in the recall confirmation dialog box. to determine.

Step S404: When the recall instruction operation is performed, the registration device 20 performs recall processing of the registered data.
Step S405: The registration device 20 that has acquired the registration data through the recall process in step S404 clears the recall confirmation dialog box displayed in step S402. In addition, when the registration data is recalled, the settlement device 30 that has transmitted the recalled registration data changes from the state of "in use" to the state of settlement processing suspension or "standby". Therefore, the registration device 20 also deletes the checkout tab TAB2 operated in response to step S401.
Step S406: The registration device 20 uses the recalled registration data to display the transaction correction screen.

Step S407: On the other hand, if the "No" button arranged in the recall confirmation dialog box is operated, the registration device 20 determines in step S403 that the recall instruction operation has not been performed, and in step S402 Clear the recall confirmation dialog box that appears.

<Third Embodiment>
Next, a third embodiment will be described. In the following description of this embodiment, FIG. 7 will be referred to as in the second embodiment.
In the product registration screen of the present embodiment, a checkout tab TAB2-1 and checkout tab TAB2-2 corresponding to each of the checkout devices 30-1 and 30-2 are constantly displayed.
The display mode of the settlement tab TAB2 of the present embodiment is changed according to the state of the corresponding settlement device. That is, when the corresponding settlement device 30 is in the "standby" state, the settlement tab TAB2 is displayed in a predetermined manner corresponding to this state, and in the standby "in use" state, a predetermined mode corresponding to this state is displayed. displayed in the form. By changing the display mode in this manner, the current state of the corresponding settlement device 30 can be indicated by the settlement tab TAB2, such as whether the corresponding settlement device 30 is on standby or in use.

After that, in the present embodiment, an operation is performed on the checkout tab TAB2 indicating the "standby" state as the checkout device specifying operation performed in response to the completion of product registration. As a specific example, when the store clerk completes the registration of the product corresponding to one transaction, he or she confirms the mode of the settlement tab TAB2 and confirms the settlement device 30 in the "standby" state. Here, since the settlement tab TAB2-1 corresponding to the settlement device 30-1 is in the standby state, the store clerk has decided that the settlement device 30-1 is the settlement device 30 to execute settlement processing. In this case, the store clerk operates the settlement tab TAB2-1 corresponding to the settlement device 30-1 among the settlement tabs TAB2.
In this way, in response to the settlement device designation operation by operating the settlement tab TAB2-1 in the "standby" state, the registration device 20 registers the settlement device 30 corresponding to the operated settlement tab TAB2-1. -1, the registration data corresponding to the product registration of this transaction is transmitted.
In addition, according to the transmission of the registration data, the settlement tab TAB2-1, which has been operated as the settlement device designation operation, changes from the mode indicating the state of "standby" to the mode indicating "in use". .

According to the above description, in the present embodiment, it is possible to specify a settlement device by operating the settlement tab TAB2. Further, in the present embodiment, the state of each settlement device 30 is also indicated by the display mode of the settlement tab TAB2. Therefore, in the present embodiment, for example, the checkout device specifying button BT1 arranged on the product registration screen of FIG. 5 may be omitted.

In addition, in the present embodiment, the registered data can be recalled by operating the checkout tab TAB2 indicating the "in use" state.
As a specific example, a request for correction of product registration such as additional registration of products or partial cancellation of registered products is made by a transaction customer corresponding to the registration data currently being processed by the settlement device 30-1. If received, it will look like this:
When the request for correction of the registered contents is received, the settlement tab TAB2-1 corresponding to the settlement device 30-1 shows the state of "in use", and is in a state in which recall target selection operation can be accepted. Therefore, the store clerk in this case operates the checkout tab TAB2-1 in order to recall the registration data corresponding to the customer who requested correction of the product registration content.
Also in the present embodiment, the recall confirmation dialog box is displayed in the same manner as in the second embodiment in accordance with the operation on the settlement tab TAB2-1. The clerk performs a recall instruction operation by operating the "Yes" button in the recall confirmation dialog box, and causes the registration device 20 to recall the registration data from the settlement device 30-1. When the registered data is recalled, a transaction correction screen is displayed, and the store clerk can perform an operation to change the registered content of the product.

<Modification>
Modifications of this embodiment will be described below.
[First modification]
In the product registration screen of each of the above-described embodiments, when there are a plurality of tabbed sheets, an example is shown in which the tabbed sheets are arranged so as to overlap each other. However, for example, a plurality of sheets may be arranged one by one in the plane direction so that they can be viewed simultaneously on the screen.

[Second modification]
Transmission of registration data from the registration device 20 to the settlement device 30 in response to the settlement device designation operation may be performed via another information processing device such as the management device 10 . Similarly, information transmission/reception between the registration device 20 and the settlement device 30 regarding recall of registration data may also be performed via another information processing device.

[Third Modification]
In each of the above-described embodiments, the recall operation recalls the registered data corresponding to the registration device 20 . In other words, the registration data that can be recalled by one registration device 20 is the registration data that the other registration device 20 has performed the product registration processing and transmitted to the settlement device 30, and the other registration device 20 has performed the commodity registration processing and sent it to the settlement device 30. It was not designed to recall the registration data that was sent.
However, due to the recall operation for one registration device 20, not only the registration data transmitted by the one registration device to the settlement device 30 but also the registration data transmitted to the settlement device 30 by the other registration device 20 It may be enabled to call back to the registration device. Thus, the store clerk can recall the registered data on the spot to correct the registered data in response to a request from a customer whose merchandise is registered by a device other than the registration device 20 operated by the store clerk.

Under such a modification, as shown in FIG. 5, a checkout machine list button BT2 may be arranged on the product registration screen. When the store clerk attempts to call back registration data corresponding to a registration device 20 other than the registration device 20 that he or she is operating, the clerk operates the checkout machine list button BT2.
In response to the operation on the checkout machine list button BT2, the registration device 20 displays a list of checkout device designation buttons corresponding to each of the other registration devices 20 (payment machine list screen). The current state of the corresponding settlement device 30 is also shown in each of the settlement device designation buttons displayed on the settlement device list screen. In other words, the "waiting" badge is displayed when the device is on standby, and the "in use" badge is displayed when the registration data has been received but the settlement process has not been completed. Looking at such a settlement machine list screen, the clerk operates a settlement device designation button corresponding to registration data that needs to be corrected. Corresponding registration data is transmitted from the specified settlement device 20 to the registration device 20 operated by the store clerk in response to the operation of the settlement device designation button. The registration device 20 displays a transaction correction screen according to the received registration data. The store clerk can correct the registered data by operating the displayed transaction correction screen. In this manner, one registration device 20 can recall and correct registration data corresponding to another registration device 20 .

The above example corresponds to the case where this modified example is applied to the first embodiment. On the other hand, when this modified example is applied to the second embodiment or the third embodiment, the payment tab TAB2 corresponding to each other registration device 20 is displayed according to the operation of the payment machine list button BT2. It should be done. The store clerk operates the settlement tab TAB2 corresponding to the registered data requiring correction from among the displayed settlement tabs TAB2, thereby displaying the transaction correction screen of the registered data requiring correction on the registration device 20 operated by the store clerk. and correct the registration data.

[Fourth Modification]
Note that a registration machine list button (not shown) may be arranged on the product registration screen. When the store clerk operates the registration device list button, a registration device list screen showing a list of other registration devices 20 is displayed. The store clerk operates a registration device specification button that has performed product registration corresponding to the registration data to be corrected, among the registration device specification buttons corresponding to the other registration devices 20 presented on the displayed registration device list screen. In response to the operation of the registration device designation button, for example, similarly to the third modified example, a fare adjustment machine list screen corresponding to each other registration device 20 is displayed. The clerk operates the payment device designation button corresponding to the registered data to be corrected from among the payment device designation buttons presented on the payment machine list screen, displays the transaction correction screen, and makes corrections on the transaction correction screen. operation can be performed.

[Fifth Modification]
When the store clerk performs an operation to select another store clerk (operator) operating another registration device 20, the other registration device 20 operated by the other selected store clerk transmits the data to the settlement device 30. The registered data may be recalled to the registration device 20 operated by the store clerk so that the data can be corrected.

[Sixth Modification]
Also, on the product registration screen, a button for recalling registered data corresponding to a transaction (immediate transaction) for which product registration has been completed on the registration device 20 but settlement has not been completed on the settlement device 30. may be placed. As such a button, FIG. 5 shows an example in which a previous recall button BT3 is arranged. When the transaction for which correction is requested is the previous transaction corresponding to the registration device 20 operated by the store clerk, the clerk operates the previous recall button BT3. In response to the operation of the previous recall button BT3, the registration device 20 recalls the registered data corresponding to the previous transaction and displays the transaction correction screen.
The recall is the registration data transmitted from the registration device 20 to the settlement device 30 and the registration data that has not yet been processed by the settlement device 30 . For this reason, the recall is often performed for the transaction for which product registration has been completed in the registration device 20 at the end, that is, the immediately preceding transaction. Therefore, as in this modified example, recalling registered data corresponding to the immediately preceding transaction can be performed with a single button operation, thereby improving the efficiency of the recalling operation.

[Seventh Modification]
Note that the recall operation is performed after the registration data to be corrected has been transmitted to the settlement device 30, and the product corresponding to the new transaction is being registered (for example, if the subtotal operation has not yet been performed since product registration started). state), it may be prohibited. As a result, product registration for new transactions is not interrupted, so that the possibility of an operational mistake by a store clerk in product registration for new transactions can be reduced.

[Eighth modification]
In addition, for example, when a customer puts purchased products in two baskets and receives product registration, the store clerk misunderstands that product registration for one transaction has been completed in the first basket, and the product in the first basket is not registered. In some cases, the customer may have performed the operation for specifying the settlement device at the stage of completing the registration, and then realized that there was a second basket. In response to such a case, for example, when a recall is performed, the store clerk can select whether or not to combine the transaction currently being registered with the transaction corresponding to the registration data to be corrected. can be
In this case, if an operation to select summation is performed, the registration device 20 corrects the recalled registration data by integrating the results of the current product registration processing. That is, in this case, for example, the transaction of the first basket and the transaction of the second basket can be integrated as one transaction.
As an example, when the same customer purchases two baskets and receives product registration, the first basket contains two products, product A and product B. The store clerk completes the registration of two products, product A and product B, corresponding to the first basket in the same manner as in the example of FIG. did. After that, when the product C and D among the products in the second basket for the same customer have been registered, the sales clerk who is currently registering the product will complete the product registration immediately before. I realized that the transaction was about the same customer as the transaction I made. In this case, the store clerk performs an operation of recalling the registered data corresponding to the first basket from the settlement device 30 . A correction screen for the recalled registration data is displayed on the registration device 20 . The store clerk performs an operation on the correction screen to select integration of the registered data corresponding to the transaction in the second basket currently being registered with the registered data to be corrected (that is, the transaction corresponding to the first basket). conduct. In response to the operation, the registration device 20 integrates the information on the products registered up to now corresponding to the transaction currently being registered in the registration data to be corrected, as a transaction correction process, to complete one transaction. Executes the process of making the corresponding product registration data. After executing such correction processing, the registration device 20 displays a product registration screen on which the integrated product registration data is reflected.

FIG. 10 shows a product registration screen reflecting the product registration data after integration under the above example. In the product registration screen shown in the figure, the product registration data after integration is reflected as follows. That is, in the registered product list area AR11, as the registration results of the products so far, the first "product A" and the second "product B" corresponding to the first basket are displayed, followed by the second basket. , "product C" is registered as the third product, and "product D" is registered as the fourth product.
In addition, as shown in the same figure, in the registered product list area AR11, the product corresponding to the registration data to be corrected recalled from the settlement device 30 (that is, the product registered corresponding to the first basket) is displayed. Change the display mode by, for example, making the background color different between the item and the item of the product registered under the transaction during product registration (that is, the product registered corresponding to the second basket). You may By changing the display mode in this way, the store clerk can easily distinguish between the product corresponding to the registration data recalled from the settlement device 30 and the products registered so far under the transaction during product registration. can do.
In the example shown in the figure, the order of arrangement of the product items in the registered product list area AR11 is the order of the products registered corresponding to the first basket, and the products registered corresponding to the second basket. It follows the chronological order (oldest first) of the transactions in which product registration was performed. However, the arrangement order of the items of the products in the registered product list area AR11 is the opposite of the above, such as products registered corresponding to the second basket, products registered corresponding to the first basket, and so on. The newest order of the trades registered may be followed. In this case, the product items may be arranged so that the order of registration of the products through the first basket and the second basket is reversed as it is, or a group of products registered corresponding to the first basket and two The order of the product groups registered corresponding to the basket may be reversed, and the product items in each group may be arranged according to the order of registration.
Further, in the registered product area AR12, information about the last registered "product D" is shown. The total amount area AR13 indicates that the total number of products registered so far is "4" and the total amount of these four products is 3000 yen.
The store clerk can further perform the operation of registering the unregistered products in the second basket from the state where the product registration screen shown in the figure is displayed. As a result, when the registration of the products in the second basket is completed, product registration data in which the products in the first basket and the products in the second basket are combined as one transaction can be obtained. By processing the registration data including the product registration data in the settlement device 30, the customer can perform the settlement operation with the purchased products in the first and second baskets as one transaction.

[Ninth Modification]
In each of the above-described embodiments, as an aspect of specifying the settlement device 30 to execute the settlement processing from among the plurality of settlement devices 30, the clerk designates the settlement device 30 to execute the settlement processing using the registration device 20. A mode (a first specified mode), and a mode (a second designated mode) in which the registration device 20 issues a settlement use receipt handed to the customer, and the customer reads the settlement use receipt handed by the clerk with one settlement device 30 (second specified mode). specification mode). However, the mode of designating the settlement device 30 is not limited to the above mode. For example, it is also possible to specify the settlement device 30 as follows.
As one aspect, according to the operation performed on the send button displayed on the salesclerk display unit 205 in response to the completion of product registration (or an operation such as declaring the completion of product registration may be performed). ), the registration device 20, for example, inquires the settlement device 30 about the state of the settlement device 30, recognizes the settlement device 30 that is capable of settlement processing (for example, there is no failure and is not in use), and the settlement device 30 that is not in use is recognized. One settlement device 30 is determined from among the 30 according to a predetermined rule (for example, in order of settlement device numbers). Then, the registration device 20 transmits settlement information to the determined settlement device 30 and instructs execution of settlement processing.
Moreover, as another aspect, the order of priority of settlement processing is set in advance for the settlement device 30 . After that, according to the completion of the product registration, the salesclerk display unit 205 is displayed so that the operation of the transmission button instructing the transmission of the settlement information to the settlement device 30 is enabled. In response to the operation of the send button, the registration device 20 confirms whether or not the settlement processing of the settlement device 30 is possible in order according to the set priority order, and confirms that the settlement processing is possible. is not confirmed, the checkout device 30 having the next priority is checked. After that, the registration device 20 transmits settlement information to the settlement device 30 that is first confirmed to be capable of settlement processing, and instructs execution of settlement processing.
