The X-axis is a horizontal axis of the product sales data processing device 1 that is horizontal to the horizontal plane. The Y-axis is an axis in the depth direction of the product sales data processing device 1, which is horizontal to the horizontal plane, in other words, in the direction toward the customer side. The Z axis is an axis in the height direction of the product sales data processing device 1 orthogonal to the horizontal plane.

FIG. 2 is a perspective view of the appearance of the product sales data processing device 1 from another viewpoint. Specifically, FIG. 2 is a perspective view when viewed from diagonally forward and upward on the clerk side. FIG. 2 shows a clerk S (product registrant) and a customer C facing each other with the counter stand 80 in between. Hereinafter, the configuration of the product sales data processing device 1 will be described with reference to FIGS. 1 and 2.

In FIGS. 1 and 2, the same configuration is designated by the same reference numeral. As shown in FIGS. 1 and 2, the product sales data processing device 1 includes a store clerk display unit 10, an operation reception unit 20, a scanner unit 30, a housing 40, a support unit 41, and a customer display unit. 50, a change machine 60, and a receipt issuing unit 70 are included. Further, the product sales data processing device 1 includes a control unit (an example of control means) (not shown). The control unit executes a product registration process for registering the purchase of the product and a settlement process (settlement process) after payment to the change machine 60.

The clerk display unit 10 is a display device that displays the product registration display information associated with the product registration process and the accounting display information associated with the settlement process. For example, the product registration display information includes information such as the product name, unit price, discount amount, and quantity of the purchased product. For example, the accounting display information includes information such as a total amount, a deposit amount, a difference (change amount), and a purchase quantity. The clerk display unit 10 presents these display information to the clerk S.

For example, the store clerk display unit 10 is realized by a liquid crystal display device with a touch panel having an operation reception function. In this case, the control unit causes the store clerk display unit 10 to display a GUI (Graphical User Interface) button such as a preset button. Then, the touch panel receives the operation input of the GUI button and supplies the operation information corresponding to the operation to the control unit. In addition, the clerk display unit 10 displays product registration display information associated with product registration processing in transaction-related processing, information associated with settlement processing, and the like.

The operation reception unit 20 includes an input unit such as a key. For example, the input unit includes a numerical key for inputting a selling price and a quantity, a preset key associated with a predetermined process, a subtotal key (product registration completion key) for ending the product registration process in the control unit, and the like.

The scanner unit 30 is an optical reading device that reads a barcode-shaped product code associated with a product and supplies product code information to the control unit while the product registration process is being executed by the control unit. For example, the scanner unit 30 is realized by a handy scanner. The scanner unit 30 is hooked on a pedestal provided on the side surface of the housing 40. The scanner unit 30 may be realized by a fixed scanner installed on the counter table 80 on the clerk S side.

The customer display unit 50 is realized by, for example, a liquid crystal display device with a touch panel having an operation reception function. In this case, the control unit causes the customer display unit 50 to display a GUI (Graphical User Interface) button such as a preset button. Then, the touch panel receives the operation input of the GUI button and supplies the operation information corresponding to the operation to the control unit. In addition, the customer display unit 50 displays product registration display information associated with the product registration process, information associated with the settlement process, and the like. The accounting key to be operated by the customer C may be realized by a hardware key instead of the GUI button. In this case, the keyboard having the accounting key is provided in the vicinity of the customer display unit 50 (for example, immediately beside or immediately before the customer display unit 50). The customer display unit 50 causes the customer display unit 50 to display a GUI button as an accounting key (accounting button).

The housing 40 is installed on the counter table 80.

Further, the operation reception unit 20 is attached to the support unit 41 or the store clerk display unit 10 and is provided with the input unit facing the store clerk S side.

The clerk display unit 10 is rotatable with respect to the vertical central axis (axis parallel to the Z axis) of the support unit 41. For example, according to FIG. 1, the store clerk display unit 10 can swing within a range that does not hit the housing 40. For example, the clerk display unit 10 may be provided so as to be rotatable approximately 180 degrees (including 180 degrees) from the front direction with respect to the clerk S.

Further, the clerk display unit 10 has a range of, for example, from 0 degrees to approximately 120 degrees (including 120 degrees) with respect to an axis orthogonal to the vertical central axis of the support unit 41 and parallel to the display surface. It may be rotatable within. However, the axis parallel to the display surface referred to here is, for example, an axis parallel to the display surface at a position where the display surface includes a vertical axis. For example, when the store clerk display unit 10 is rotated 120 degrees with respect to an axis orthogonal to the vertical central axis of the support unit 41 and parallel to the display surface, the store clerk display unit 10 moves up and down. Will be installed in reverse. Therefore, in this case, the control unit controls the store clerk display unit 10 so that the scanning of the display screen is reversed so that the display is not reversed.

Further, on the right side of the change column 404 or the like, an image reminiscent of receiving the change or the like is displayed. In the example of FIG. 11, the arrow from the discharge port is displayed by animation (moving image).
The information that guides the customer to change and receive the receipt on the accounting screen shown in FIG. 11 is referred to as receipt receipt guidance information.

According to the above explanations of FIGS. 5 to 11, the actions up to the settlement performed by the first customer according to his / her transaction are as follows.
That is, when the customer goes to the product sales data processing device 1 and hands the product to be purchased to the clerk, the clerk starts registering the product. In response to the registration of the product, the accounting screen is displayed on the customer display unit 50 as shown in FIG. 6A. In response to the state in which the accounting screen is displayed in this way, the change machine 60 in the product sales data processing device 1 is in a state of being able to accept payment from the customer. That is, the customer confirms the total amount up to the present displayed in the total column 401 of the accounting screen even if the total amount of the upper product is not fixed before the subtotal key operation is performed. At the same time, you can deposit the price. The figure shows an example in which a customer can make a deposit to the change machine 60 after the first product is registered. However, it may be possible to make a deposit to the change machine 60 even when the product corresponding to the customer has not been registered yet.
Then, as the payment is made, on the accounting screen, as shown in FIG. 6B, the deposit amount up to now in the deposit column 402 changes according to the deposit amount. Therefore, the customer can confirm the amount of money deposited by the amount indicated in the deposit column 402.

Then, while the customer is depositing money, when the clerk completes the registration of all the purchased products of the customer and operates the subtotal key, the accounting screen in the customer display unit 50 is shown in FIG. 8 (B), for example. Changes to.
Then, when the customer deposits an amount equal to or more than the total amount to the change machine 60, the accounting screen on the customer display unit 50 changes to the content shown in FIG. 9A or FIG. 9B. If there is change, the customer is notified of the amount of change and the discharge of change after a while.
Then, in the case of the present embodiment, the window 500 is displayed as shown in FIG. 10 when the display of FIG. 9A or FIG. 9B is being performed on the customer display unit 50. Therefore, the clerk operates the accounting key 507 arranged in the window 500 in order to end the settlement process corresponding to the window 500.

In response to the operation of the accounting key 507, the accounting screen in the customer display unit 50 changes to the state shown in FIG. Then, under the state where the accounting screen in the state shown in FIG. 11 is displayed, the change is discharged from the bill discharge port 63 and the coin discharge port 65, and the receipt is further discharged from the receipt issuing unit 70.
As described above, when the discharge of change and the discharge of receipt are completed, the settlement process is completed. That is, the transaction-related processing corresponding to one customer is completed.
The customer takes out the discharged change from the bill discharge port 63 and the coin discharge port 65, and collects the receipt from the receipt issuing unit 70.

In the above description, the transaction-related processing of one customer is started from the standby state in which the transaction-related processing has not been performed in the product sales data processing device 1 of the present embodiment, and the next customer is also in the middle of the transaction-related processing of one customer. This is an example in which the transaction-related processing of one customer is completed without starting the transaction-related processing of.
However, in the product sales data processing device 1 of the present embodiment, the clerk is in the middle of the transaction-related processing of one customer (previous customer or first customer), and the transaction-related of the next customer (second customer or second customer). The process can be started.
That is, when trying to start the transaction-related processing of the second customer in response to the appearance of the second customer while registering the product corresponding to the first customer, the clerk as shown in FIG. The operation is performed on the next customer registration key 309 arranged on the product registration screen corresponding to the displayed first customer.
In response to the operation for the next customer registration key 309, the store clerk display unit 10 switches to the display of the product registration screen corresponding to the second customer, as shown in FIG. As a result, it becomes possible to register the product corresponding to the second customer. The figure shows an example of a product registration screen when the first product corresponding to the second customer, "fluffy loco moco bowl", is registered.

Here, in FIG. 12, the product registration screen corresponding to the second customer is displayed in a manner superimposed on the product registration screen corresponding to the first customer.
That is, in the figure, first, the selection area 320, which is a tab corresponding to the product registration screen of the second customer, is arranged. In the selection area 320, information 324 (value "1") indicating that the second customer is displayed, the deposit amount 321 up to now, the total amount 322 up to now, and the second customer as the first customer. The character 323 (cow in FIG. 12) for identifying the character is displayed.
As the display priority, "1" may be displayed in the information 324 of the selection area 320 corresponding to the second customer, and "2" may be displayed in the information 304 of the selection area 300 corresponding to the first customer. ..

Then, on the right side of the selection area 320, a selection area 300, which is a tab corresponding to the product registration screen of the first customer, is arranged. By arranging the selection area 300 in this way, it is clearly shown that the product registration screen of the first customer is arranged below the product registration screen of the second customer.
For example, when the clerk performs an operation on the selection area 300, the clerk display unit 10 displays the product registration screen corresponding to the first customer in a manner of moving to the front from the state shown in FIG. The product registration screen corresponding to the customer is arranged at the lower side of the product registration screen corresponding to the first customer.
That is, in the store clerk display unit 10 of the present embodiment, when the transaction-related processing between the first customer and the second customer is started, the transaction-related information of the second customer is displayed and the transaction of the first customer is performed. Display of related information is performed.

In the present embodiment, the operation (switching to the product registration screen of the first customer) for the selection area 300 under the state of FIG. 12 is always effective.
Alternatively, for example, when the product registration corresponding to the second customer is performed, the operation for the selection area 300 is not accepted in order to give priority to the product registration (the first customer cannot switch to the product registration screen). ) May be done. Then, when the operation of the subtotal key corresponding to the second customer is performed and the product registration is completed, the operation for the selection area 300 may be accepted.

Here, for example, although the subtotal key is operated in response to the first customer to shift to the settlement process, the first customer may take time to settle the settlement for some reason, and the settlement may not be completed easily. .. In such a case, for example, before the first customer finishes the settlement, the subtotal key may be operated even if the second customer is dealt with, and the settlement may be possible. That is, there is a possibility that both the first customer and the second customer can make a payment.
In such a case, for example, in response to the fact that it is possible to settle the payment for the second customer, in addition to the accounting screen corresponding to the first customer, which has been displayed so far on the customer display unit 50, the second customer is displayed. It is possible to display the corresponding accounting screen for two customers. However, when the accounting screen corresponding to the first customer and the accounting screen corresponding to the second customer are displayed on the same customer display unit 50 in this way, for example, the first customer who is trying to make a payment mistakenly makes a second customer. There is a possibility that the customer will be confused because the settlement process will be performed on the accounting screen corresponding to the two customers.

Therefore, as described above, the product sales data processing device 1 of the present embodiment completes the settlement process corresponding to the first customer even if the first customer and the second customer can be settled. Until then, it is prohibited to display the accounting screen corresponding to the second customer on the customer display unit 50.
Then, when it is determined that the product sales data processing device 1 is in a predetermined state after the settlement process of the first customer is completed and the accounting screen corresponding to the first customer is erased, the second customer is notified. Display the corresponding accounting screen.

Here, referring to FIG. 13, the accounting screen corresponding to the second customer is displayed in response to the completion of the settlement process of the first customer and the removal of the prohibition on the display of the accounting screen corresponding to the second customer. An example of the timing of displaying on the customer display unit 50 will be described.
In FIG. 13, it is shown that the transaction-related processing corresponding to the first customer was performed from the time t1 to the time t2.
Here, the timing of the end of the transaction-related processing corresponding to the first customer indicated as the time t2 is the accounting screen including the receipt receipt guidance information (notifying the completion of the settlement processing corresponding to the first customer) as shown in FIG. Corresponds when an example of display) is displayed. The accounting screen including the receipt receipt guidance information displayed corresponding to the time t2 may be deleted, for example, after a certain period of time, and may be switched to, for example, a standby screen of a predetermined mode.

In addition, the figure shows the transaction-related processing patterns corresponding to the three second customers. Note that the figure shows a case where the transaction-related processing corresponding to the second customer is started from the same time t10 for the convenience of simplifying the explanation of the three patterns. The time t10 is a certain time in the period during which the transaction-related processing corresponding to the first customer is being performed.

The three transaction-related processing patterns corresponding to the second customer show pattern examples of the state in which the second customer should display the corresponding accounting screen after the time t2 when the settlement processing of the first customer is completed. There is.
First, pattern 1 of transaction-related processing corresponding to the second customer will be described. In pattern 1, the first product is registered at time t11 when a certain time has passed from the time t10 when the transaction-related processing is started, and the second product is registered at time t12 when a certain time has passed from time t11. The product is registered. The registration of the first and second products is performed at a timing before the time t2 when the transaction-related processing corresponding to the first customer is completed.
Then, following the registration of the product at the time t12, the registration of the third product is performed at the time t13 when a certain time has passed from the time t2.
First, in the product sales data processing device 1 of the present embodiment, if the product registration is performed after the time t2 when the settlement process of the first customer is completed, as in the above time t13, the product registration is performed. Is performed, the display of the second customer's accounting screen is started.

Next, pattern 2 of transaction-related processing corresponding to the second customer will be described.
In the pattern 2, the first to third products are sequentially registered at the times t21, t22, and t23 that are before the time t2 and a certain time has passed from the time t10.
After that, the subtotal key is operated at the time t24 when a certain time has passed from the time t2. If the subtotal key is operated after the transaction-related processing corresponding to the first customer is completed in this way, the product sales data processing device 1 causes the second customer to start displaying the corresponding accounting screen. ..

Next, pattern 3 of transaction-related processing corresponding to the second customer will be described.
In the pattern 3, the first and second products are sequentially registered at the times t31 and t32 when a certain time has passed from the time t10 before the time t2. Then, the subtotal key is operated at time t33, which is before time t2 and a certain time has passed from time t22.
In this way, if the subtotal key for the second customer is operated before the transaction-related processing corresponding to the first customer is completed, the product sales data processing device 1 corresponds to the second customer at the following timing. Start displaying the accounting screen.
That is, the product sales data processing device 1 starts displaying on the customer display unit 50 corresponding to the time t2, from the time t34 after the display time T1 of the accounting screen (FIG. 11) including the receipt receipt guidance information has elapsed. , The second customer is made to start displaying the corresponding accounting screen.
As in the case of pattern 3, when the subtotal key corresponding to the second customer is operated before the transaction-related processing corresponding to the first customer is completed, the display unit 10 for the clerk illustrates in FIG. An example of a message window MSG (information indicating that the settlement process is waiting) for notifying the clerk to wait for the accounting key operation corresponding to the corresponding settlement. ) Is displayed.

As described above, in the product sales data processing device 1 of the present embodiment, the customer display unit 50 corresponds to the second customer according to the state of any one of the above three patterns 1 to 3. The display of the accounting screen of is started.
That is, after the transaction-related processing of the first customer is completed (that is, the settlement processing is completed), the accounting corresponding to the second customer is performed according to the state in which the product registration corresponding to the second customer is performed. The screen display is started (Pattern 1).
In addition, after the transaction-related processing of the first customer is completed, the display of the accounting screen corresponding to the second customer is started according to the state in which the operation of the subtotal key corresponding to the second customer is performed. (Pattern 2).
Further, if the subtotal key corresponding to the second customer has already been operated before the transaction-related processing of the first customer is completed (that is, the settlement processing is completed), the transaction-related processing of the first customer is performed. When completed, the display of the accounting screen corresponding to the second customer is started (Pattern 3).

As can be understood from the above description, the product sales data processing device 1 in the present embodiment can execute the transaction-related processing of the second customer together with the transaction-related processing of the first customer. Then, the product sales data processing device 1 prohibits the display of the accounting screen corresponding to the second customer in the customer display unit 50 until the settlement processing corresponding to the first customer is completed, and corresponds to the first customer. The accounting screen corresponding to the second customer is displayed at a predetermined timing after the settlement process is completed.
As a result, for example, even if the product registration for the second customer is completed and the second customer can be settled while the first customer is confused by the settlement, the settlement is made corresponding to the second customer. The accounting screen for performing the above is not displayed on the customer display unit 50. As a result, for example, the customer does not accidentally make a payment on an accounting screen that does not correspond to him / her, it becomes possible to avoid confusion in the payment, and the efficiency of customer handling is improved.

Subsequently, with reference to the flowchart of FIG. 15, an example of a processing procedure executed by the product sales data processing device 1 in the present embodiment regarding the display of the customer display unit 50 will be described.
The process shown in the figure is started under the condition that only the transaction-related process corresponding to the first customer is performed. Therefore, when the process of FIG. 10 is started, the clerk display unit 10 corresponds to, for example, any of FIGS. 5, 7, and 10 depending on the progress of the transaction-related process. The product registration screen corresponding to only one customer is displayed.

First, the control unit in the product sales data processing device 1 is waiting for the start instruction of the transaction-related processing corresponding to the second customer to be obtained (step S101-NO).
Then, for example, when an operation on the next customer registration key 309 of FIG. 5 or the next customer registration key 509 of FIG. 7 or FIG. 10 is performed by a clerk, an instruction to start transaction-related processing corresponding to the second customer is obtained. (Step S101-YES).
In this case, the control unit displays the product registration screen corresponding to the second customer on the store clerk display unit 10 so as to be superimposed on the product registration screen of the first customer as described with reference to FIG. Step S102). After the product registration screen corresponding to the second customer is displayed by the process of step S102, the control unit can perform the product registration process corresponding to the second customer in response to the product registration operation by the clerk.

In the state where the transaction-related processing corresponding to the second customer is started as described above, the control unit waits for the payment of the total amount or more of the products to be completed as the settlement processing of the first customer (step S103). -NO).

As described above, when it is determined in the settlement process corresponding to the first customer that the payment of the total amount or more of the products has been completed (step S103-YES), the control unit performs the following process.
That is, the control unit displays the accounting screen including the receipt receipt guidance information corresponding to the first customer on the customer display unit 50, and discharges the change and the receipt (step S104). If the total amount of the goods and the deposit amount are the same, no change will be discharged.
Further, in the process of step S104, a certain display time for the accounting screen including the receipt receipt guidance information, which is set in consideration of the time required for the customer to receive the change and the receipt, has elapsed, and the receipt receipt guidance information is included. It ends when the accounting screen is deleted. Then, by the end of the process in step S104, the transaction-related process corresponding to the first customer is completed.

Further, upon completion of the transaction-related processing corresponding to the first customer, the control unit deletes the product registration screen corresponding to the first customer in the clerk display unit 10 (step S105). As a result, only the product registration screen corresponding to the second customer is displayed on the clerk display unit 10.

Here, in the period from the start of the transaction-related processing corresponding to the second customer in accordance with step S102 to the completion of the transaction-related processing corresponding to the second customer in step S104, for example, the second customer The corresponding processing for the second customer, such as the corresponding product registration processing or the instruction to complete the product registration by operating the subtotal key, may be performed in parallel. However, until the transaction-related processing of the first customer is completed, even if the processing corresponding to the second customer is executed, the customer display unit 50 responds to the execution of the processing corresponding to the second customer. The corresponding accounting screen is not displayed for the second customer.
That is, the processing of steps S102 to S104 corresponds to the control of prohibiting the display of the accounting screen corresponding to the second customer until the transaction-related processing of the first customer is completed as the display control.

Hereinafter, the control unit controls the customer display unit 50 to display the transaction-related processing corresponding to the second customer according to the state corresponding to any of the patterns 1 to 3 described with reference to FIG. To execute.
Therefore, first, the control unit has already performed the subtotal key operation corresponding to the second customer until the transaction-related processing corresponding to the first customer is completed (that is, until the processing in step S104 is completed). It is determined whether or not it has been performed (step S106). The determination in step S106 is a determination as to whether or not a state corresponding to the pattern 3 described with reference to FIG. 13 is obtained.

When the subtotal key operation corresponding to the second customer has already been performed (step S106-YES), the control unit executes step S109 described later.
On the other hand, when it is determined that the subtotal key operation corresponding to the second customer has not been performed yet (step S106-NO), the control unit performs the second after the completion of the transaction-related processing corresponding to the first customer. It is determined whether or not the subtotal key operation corresponding to the customer has been performed (step S107). The determination in step S107 is a determination as to whether or not a state corresponding to the pattern 2 described with reference to FIG. 13 is obtained.

When it is determined that the subtotal key operation corresponding to the second customer has been performed (step S107-YES), step S109 described later is executed.
On the other hand, when it is determined that the subtotal key operation corresponding to the second customer has not been performed after the transaction-related processing corresponding to the first customer is completed (step S107-NO), the control unit controls the second customer. It is determined whether or not the product registration corresponding to the above is performed (step S108). The determination in step S108 is a determination as to whether or not a state corresponding to the pattern 1 described with reference to FIG. 13 is obtained.
When it is determined that the product registration corresponding to the second customer has not been performed (step S108-NO), the control unit returns the process to step S107.
