Therefore, product registration device 100 in this embodiment includes both blocks that function as a master device and blocks that function as a slave device. Note that any one of the plurality of product registration devices 100 may include only the functions of a slave device.

(First reception section 110)
The first reception unit 110 corresponds to the first reception unit 11 in the first embodiment. The first reception unit 110 functions when the product registration device 100 is a master device. When the product registration device 100 is a parent device, the first reception unit 110 receives from each payment device 200 the theoretical value of the amount to be paid by the payment device 200 and the amount remaining in the payment device 200. As described above, the amount in stock is the total value of at least one of the information on the payment amount when payment is made using cash, coupons, credit cards, etc. In other words, the balance in the settlement device 200 refers to cash stored in the settlement device 200, coupons stored in the settlement device 200, and credit payment information when settlement is performed using a credit card or the like in the settlement device 200. At least one of the total values. In this embodiment, the amount in the settlement device 200 will be explained as the total value of cash and/or coupons stored in the settlement device 200. May contain values. Among the product registration devices 100 shown in FIG. 3, if the product registration device 100-1 is the master device, the product registration device 100-1 receives the theoretical value and the amount of money in the payment device 200-1 from the payment device 200-1. I accept that. Further, in the above case, the product registration device 100-1 receives the theoretical value and the amount of money in the payment device 200-2 from the payment device 200-2.

In this embodiment, payment device 200-1 receives payment information from product registration device 100-1 and product registration device 100-2, and performs payment based on the payment information. Therefore, the theoretical value of the amount settled by the settlement device 200-1 is the total amount included in the settlement information received by the settlement device 200-1. Similarly, the theoretical value of the amount to be settled by the settlement device 200-2 is the total amount of money included in the settlement information received by the settlement device 200-2.

Here, for example, when making a payment based on the payment information sent from the product registration device 100-1 to the payment device 200-1, the payment device 200-1 can perform the payment using cash and/or coupons. . Note that the payment device 200-1 may perform payment using a credit card or the like. By performing this settlement, the settlement device 200-1 transmits the amount of cash and/or coupons stored in the settlement device 200-1 to the parent device. As a result, the first reception unit 110 of the product registration device 100, which is the parent device, receives the amount of cash and/or coupons stored in the payment device 200-1 from the payment device 200-1. Similarly, the first reception unit 110 of the product registration device 100, which is the parent device, receives the amount of cash and/or coupons stored in the payment device 200-2 from the payment device 200-2.

The first receiving unit 110 supplies the total of the theoretical values received from each of the payment devices 200 and the total amount of each payment device 200 to the first processing unit 130.

(Second reception section 120)
The second reception unit 120 corresponds to the second reception unit 12 in the first embodiment. The second reception unit 120 functions when the product registration device 100 is a master device. When the product registration device 100 is a master device, the second reception unit 120 receives the amount of money paid by the parent device and the amount paid by the child device. For example, in the case of payment using cash and/or coupons that cannot be handled by the payment device 200, the product registration device 100 performs payment using cash and/or coupons based on the payment information sent to the payment device 200. . Further, for example, based on the payment information sent by the product registration device 100 to the payment device 200, the payment system 1 performs payment by accepting part of the amount at the product registration device 100 and receiving the remaining amount at the payment device 200. There are cases. The second reception unit 120 receives the amount of cash and/or coupons stored in the product registration device 100 when the product registration device 100 performs payment in relation to the payment information. The second reception unit 120 may accept the amount of money of the slave device by receiving information indicating the amount of money of the slave device from the slave device. Further, the second reception unit 120 may receive the amount of money in the parent device by, for example, being input by a store clerk using an input device. In addition, in the case of an operation in which cash and/or coupons stored in the slave device are moved into the parent device, the second reception unit 120 reports the amount of cash and/or coupons stored in the parent device after the transfer, for example, The store clerk may input the amount of money on the parent device and the child device using an input device to receive the information. Note that credit payment information may be included in the balance of the master device and the balance of the slave device.

The second reception unit 120 supplies the received balance of the parent device and the balance of the child device to the first processing unit 130.

(Second processing unit 140)
The second processing unit 140 functions when the product registration device 100 is a slave device. When the product registration device 100 is a child device, the second processing unit 140 performs the following processing based on the amount of money in stock that was settled using settlement information different from that of the settlement device that the product registration device 100 sent to the settlement device 200. Performs the closing process for the slave device. After the product registration device 100 generates settlement information for each transaction, the product registration device 100 may perform settlement without transmitting the settlement information to the settlement device 200. In such a case, the payment information generated by the product registration device 100 will be payment information different from the payment information transmitted by any of the product registration devices 100 to the payment device 200. Therefore, the product registration device 100 stores cash and/or coupons that have been settled by the product registration device 100 using settlement information that has not been sent to the settlement device 200 (referred to as unsent settlement information). When the product registration device 100 is a slave device, the slave device uses the unsent payment information stored in the slave device to calculate the amount of cash and/or coupons settled by the product registration device 100. Execute the closing process for the slave device. For example, the second processing unit 140 receives input of the total amount of cash and the total amount of vouchers settled by the product registration device 100 using the unsent settlement information. Note that the total amount of cash may include the amount of reserve money stored in the product registration device 100 in advance. In this way, the closing process (for example, the amount aggregation process such as the above-mentioned cash register closing process) is performed in the slave device.

Note that the second processing unit 140 may supply the output unit 160 with the remaining amount of money settled by the slave unit based on the unsent payment information obtained by the closing process of the slave unit. Further, the second processing unit 140 may transmit the amount of money settled by the slave unit to the base unit via a transmitting unit (not shown).

Note that the child device transmits the balance of the amount settled by the child device to the parent device regarding the settlement information, asynchronously with the closing process of the child device. The second reception unit 120 of the parent device receives the amount of money transmitted to the parent device as the amount of money of the child device. Note that, as described above, the amount of money (cash and/or coupons) settled on the child device regarding the payment information may be transferred to the parent device. Furthermore, regarding the settlement information, information indicating the amount of money settled by the slave device may be transmitted from the slave device to the base device.

(First processing unit 130)
The first processing unit 130 functions when the product registration device 100 is a slave device. The first processing unit 130 receives the theoretical value and the balance of the payment device 200 from the first reception unit 110 . Further, the first processing unit 130 receives the amount of money of the parent device and the amount of money of the child device from the second reception portion 120. Then, the first processing unit 130 performs a closing process of the master device, which is a process of totaling the amount based on the theoretical value, the amount in the payment device 200, the amount in the parent device, and the amount in the child device. Execute. The closing process of the parent device is to check whether there is any discrepancy in the calculation using, for example, the theoretical value, the amount of money in the settlement device 200, the amount of money in the parent device, and the amount in the child device. Note that the closing process of the parent device is not limited to this. In addition, the closing process of the base unit adds up the amount settled in relation to the settlement information sent and received in the settlement system 2 and the amount settled in the base unit using the unsent settlement information. This process is also called the closing process of the settlement system 2.

An example of the closing process of the payment system 1 performed by the first processing unit 130 will be described. As described above, the product registration device 100, which is the master device, may perform payment using cash and/or coupons based on the payment information sent to the payment device 200. Furthermore, the base device may perform payment using unsent payment information, similar to the child device. Therefore, the following (A) and (B) are stored in the base device.
(A) Cash and/or vouchers settled based on unsent settlement information;
(B) Cash and/or vouchers settled on the parent device regarding settlement information.

In addition, in the case of an operation in which cash and/or coupons stored in the slave device are transferred to the parent device, the parent device stores the cash and/or coupons settled by the slave device regarding (C) settlement information. Ru. Further, the parent device may include a reserve amount stored in advance. The second reception unit 120 described above receives the total amount of (A) to (C) as the balance of the parent device. For example, when a store clerk inputs cash and/or coupons stored in the parent device, the second reception unit 120 receives the amount of money in the parent device. In this way, it is assumed that the clerk is made to input the total amount without having the store clerk know what kind of information was used to calculate the cash and/or coupons stored in the parent device.

Since the theoretical value is the total amount of cash and/or coupons to be settled based on the settlement information sent to the settlement device 200, the difference between the theoretical value and the settlement device 200 is the amount calculated in (B) and (C) above. This will be the total amount. Since the amount of money in the parent device received by the second reception unit 120 is the total amount of (A) to (C), the first processing unit 130 can use this information to calculate (A). can.

In this way, if the clerk enters the total amount of cash and/or coupons stored in the parent device without knowing what information was used to settle the cash and/or coupons stored in the parent device, Even if it is, the settled cash and/or vouchers can be calculated based on the unsent settlement device.

The first processing unit 130 outputs the calculated amount of “(A) cash and/or vouchers settled based on unsent settlement information” and the total amount of (A) to (C) to the output unit 160. supply to. Note that the first processing section 130 may supply the theoretical value to the output section 160.

(Display control unit 150)
The display control unit 150 causes the display unit 170 to display a selection screen for selecting whether to execute the closing process for the master device or the closing process for the slave device. FIG. 5 is a diagram showing an example of the selection screen SS1 that the display control unit 150 displays on the display unit 170. In the selection screen SS1 shown in FIG. 5, "self-register settlement" is an object C51 for receiving an instruction to execute the closing process of the slave machine, and "batch settlement" is the execution of the closing process of the master machine, that is, This is an object C52 for receiving an instruction to execute the closing process of the settlement system 1.

In the selection screen SS1 shown in FIG. 5, when the object C51 of "self-register payment" is selected, the product registration device 100 makes itself a slave device. In other words, the second processing unit 140 executes the closing process for the slave device. When the object C52 of "lump payment" is selected, the product registration device 100 sets itself as the parent device. In other words, the first reception unit 110 accepts the theoretical value and the balance of the settlement device 200, the second reception unit 120 accepts the balance of the master unit and the balance of the slave unit, and the first processing unit 130 accepts the balance of the master unit and the balance of the slave unit. Execute the process (closing process of the settlement system 1).

In this way, for example, the store clerk simply selects whether to perform the closing process for the parent device or the closing process for the slave device, and the product registration device 100 can perform the closing process for the parent device or the closing process for the slave device. Closing processing can be executed.

(Output section 160)
The output unit 160 outputs information related to the closing process performed by the product registration device 100 itself. Specifically, when the product registration device 100 is the master device, the output unit 160 receives information from the first processing unit 130 about the amount of cash and/or coupons settled based on (A) unsent settlement information. , and receive the total amount of (A) to (C). The amount of cash and/or coupons settled by the parent machine and the amount of cash and/or coupons settled by the parent device using information different from the settlement information are output. The amount of cash and/or coupons settled on the parent device is the total amount of (A) to (C) described above, and is the amount of money received by the second reception unit 120. Further, the amount of cash and/or coupons settled on the parent device using information different from the settlement information is the amount of (A) described above.

The method by which the output unit 160 of the parent device outputs the total amount of (A) to (C) and the amount of money in (A) is not particularly limited, and may be displayed on the display unit 170 described above, or may be It may be a method. For example, the output unit 160 may print and output the total amount of (A) to (C) and the amount of money (A) on a sheet of paper. FIG. 6 shows an example of an amount receipt when the output unit 160 prints the total amount of (A) to (C) and the amount of money (A) on a sheet of paper and outputs it as an amount receipt. As shown in Figure 6, on the cash receipt R61, the total amount of cash (A) to (C) and the total amount of cash vouchers (A) to (C) are shown to the right of the character string "Total". It is printed. Further, on the balance receipt R61, the cash balance (A) and the cash voucher balance (A) are printed to the right of the character string "base machine".

In this manner, the output unit 160 may output a paper (amount receipt R61) as shown in FIG. Note that the information included in the balance receipt R61 is not limited to this, and for example, a theoretical value may be output. Further, when the master device receives from the slave device the amount of cash and/or coupons settled by the slave device, the output unit 160 outputs the amount of cash and/or coupons settled by the slave device. may be output.

Further, when the product registration device 100 is a slave device, the output unit 160 may output the amount of cash and/or coupons settled by the slave device.

In this way, the output unit 160 outputs the total amount of (A) to (C) and the amount in stock of (A), so that the product registration device 100 allows the store clerk who operates the product registration device 100 to The result of the closing process in step 1 can be easily understood.

Next, the processing of the product registration device 100 will be described with reference to FIGS. 7 and 8. As described above, when the object C51 of "self-register payment" is selected on the selection screen SS1 shown in FIG. Then, the product registration device 100 executes the closing process of the parent device. In the following, with reference to FIG. 7, when the product registration device 100 is a child device, that is, when the product registration device 100 is the product registration device 100 where the object C51 of “self-register payment” is selected, the product The flow of the registration device 100 will be explained. FIG. 7 is a flowchart illustrating an example of the processing flow of the slave device.

As shown in FIG. 7, the product registration device 100 confirms whether an instruction to execute the closing process for the slave unit has been received (step S71). For example, the product registration device 100 checks whether "self-register payment" is selected on the selection screen SS1 shown in FIG. 5. If the instruction to execute the child device closing process has not been received (NO in step S71), the product registration device 100 ends the process. When receiving an instruction to execute the child device closing process (YES in step S71), the product registration device 100 sets itself as a child device. Then, the second processing unit 140 executes a closing process for the slave device (step S72). With the above, the child device ends the process. Note that the output unit 160 of the slave device may output a cash balance receipt in which the cash balance of the slave device and the cash balance of the slave device obtained by the closing process of the slave device are printed.

Next, referring to FIG. 8, when the product registration device 100 is the master device, that is, when the product registration device 100 is the product registration device 100 from which the object C52 of “collective payment” is selected, the product registration is performed. The flow of the apparatus 100 will be explained. FIG. 8 is a flowchart illustrating an example of the process flow of the parent device.

As shown in FIG. 8, the product registration device 100 confirms whether an instruction to execute the closing process of the parent device has been received (step S81). For example, the product registration device 100 checks whether "collective payment" is selected on the selection screen SS1 shown in FIG. 5. If the instruction to execute the closing process of the parent device has not been received (NO in step S81), the product registration device 100 ends the process. If the instruction to execute the closing process for the parent device is received (YES in step S81), the product registration device 100 sets itself as the parent device. In other words, the product registration device 100 performs the following steps from step S82 onwards, triggered by receiving the instruction to execute the closing process of the parent device. Upon receiving the above instruction, the first reception unit 110 receives the theoretical value of the amount to be settled by the settlement device 200 and the amount of money in the settlement device 200, which is indicated by the settlement information (step S82).

Further, the second reception unit 120 receives the amount of money settled on the parent device and the amount of money paid on the slave device (step S83). Note that step S82 and step S83 may be performed simultaneously or in reverse order.

Then, the first processing unit 130 calculates the amount of the parent device based on the theoretical value and the amount of money in the settlement device 200 received in step S82, and the amount of money in the parent device and the amount in the child device received in step S83. A closing process is executed (step S84).

After that, the output unit 160 outputs, for example, the above-mentioned money receipt R61 (step S85), and the parent device ends the process.

As described above, the product registration device 100, which is the parent device, uses the inventory amount and theoretical value of each payment device 200 in the payment system 2, the amount of the parent device, and the amount of the child device, and uses the amount of money in the payment system 2. Perform the closing process. Therefore, without having to perform closing processing in each of the plurality of product registration devices 100 and settlement devices 200, closing processing for the entire settlement system 2 can be performed only by the product registration device 100, which is the master device. Therefore, according to the payment system 2 according to the present embodiment, it is possible to reduce the effort required for the closing process in the payment system 2.

In addition, the product registration device 100, which is a slave device, performs closing processing for the slave device based on the balance of the amount settled by the slave device using settlement information different from the settlement information sent to the settlement device 200. Sends the balance of the settled amount in relation to the settlement information to the base unit. Thereby, the tightening process of the slave device can be appropriately performed.

In this embodiment, a configuration in which the product registration device 100 has both the functions of a parent device and the functions of a child device has been described. The product registration device 100 having the functions may be predetermined. In this case, the product registration device 100 having the function of a parent device includes a first reception section 110, a second reception section 120, and a first processing section 130. Further, the product registration device 100 having the function of a parent device may further include a display control section 150, an output section 160, and a display section 170. Further, the product registration device 100 having the function of a slave device includes a second processing section 140. Further, the product registration device 100 having the function of a slave device may further include a display control section 150, an output section 160, and a display section 170.

<Third embodiment>
Next, a third embodiment of the present disclosure will be described. In the second embodiment described above, it has been explained whether the product registration device 100 executes the closing process for the master device or the closing process for the slave device depending on the object selected on the selection screen SS1. In this embodiment, a method for determining whether product registration device 100 is a master device or a slave device without depending on selection will be described.

FIG. 9 is a functional block diagram showing an example of the functional configuration of product registration device 101 in this embodiment. For convenience of explanation, blocks similar to those described in the second embodiment described above are given the same reference numerals, and the explanation thereof will be omitted. In addition, the payment system 2 including the product registration device 101 in this embodiment has the product registration device 101 (100-1 and 100-2) in place of the product registration device 100 (100-1 and 100-2) of the payment system 2 described using FIG. 101-1 and 101-2), and the other configurations are the same, so a description thereof will be omitted.

As shown in FIG. 9, the product registration device 101 according to the present embodiment includes a first reception section 110, a second reception section 120, a first processing section 130, a second processing section 140, an output section 160, A determination unit 180 is provided. Note that the product registration device 101 may be configured to further include the display control section 150 and the display section 170 described in the second embodiment. This configuration will be explained in a modified example.

The determining unit 180 determines whether the child device closing process has been executed in all product registration devices 101 different from the own device (product registration device 101). For example, when the product registration device 101 including the determination unit 180 is the product registration device 101-1, the determination unit 180 determines whether the child device closing process has been executed in the product registration device 101-2. Note that the method of determination by the determination unit 180 is not particularly limited. For example, the determination unit 180 transmits a notification to all other product registration devices 101 inquiring whether the closing process for the slave device has been executed, and all responses to the notification indicate that the closing process has been executed. In this case, it may be determined that the slave device closing process has been executed in all product registration devices 101 different from the own device.

If the determining unit 180 determines that the child device closing process has been executed in all of the product registration devices 101 different from the own device, the determining unit 180 sets the own device as the master device. In addition, if it is not determined that the slave device closing process has been executed in all of the product registration devices 101 different from the own device, in other words, at least one of the product registration devices 101 different from the own device In the step, if the closing process of the slave device is not executed, the own device is set as the slave device. Note that the determination unit 180 may store a flag indicating the setting result (for example, 1 in the case of the master device, 0 in the case of the slave device) in a storage unit or the like (not shown).

The determination unit 180 then supplies the setting result to the first processing unit 130 or the second processing unit 140. If the setting result is that of the master device, the first reception unit 110 receives the theoretical value and the amount of money in the payment device 200 from each payment device 200, the second reception portion 120 receives the amount of the child device, and the first The processing unit 130 executes the closing process of the parent device. In other words, the first reception unit 110, the second reception unit 120, and the first processing unit 130 operate when the determination unit 180 determines that the child device closing process has been executed in all product registration devices 100 different from the determination unit 180. do. On the other hand, if the setting result is a slave device, the second processing unit 140 executes a closing process for the slave device.

Note that the determination unit 180 may be provided in the product registration device 101 when the product registration device 101 executes the closing process of the master device or the closing process of the slave device according to the setting result. For example, if the product registration device 101 includes the second processing unit 140 but does not include the first reception unit 110, the second reception unit 120, and the first processing unit 130, the product registration device 101 includes the determination unit 180 may not be provided. That is, the payment system 2 according to the present embodiment may have a configuration in which at least one of the plurality of product registration devices 101 includes the determination unit 180.

FIG. 10 is a flowchart showing an example of the processing flow of the product registration device 101 in this embodiment. Note that the same processes as those shown in FIGS. 7 and 8 are given the same reference numerals, and detailed explanation thereof will be omitted.

First, the determining unit 180 determines whether the child device closing process has been executed in all product registration devices 101 different from the own device (product registration device 101) (step S101). If the slave device closing process is not executed in at least one of the product registration devices 101 different from the own device (NO in step S101), the determination unit 180 sets the own device as the slave device. The determination unit 180 then supplies the setting result to the second processing unit 140. Thereby, the second processing unit 140 executes the tightening process of the slave device according to the setting result (step S72).

If the slave device closing process is executed in all of the product registration devices 101 different from the own device (YES in step S101), the determination unit 180 sets the own device as the master device. The determination unit 180 then supplies the setting result to the first processing unit 130. The first processing unit 130 that has received the setting result transmits an instruction to the first reception unit 110 to receive the theoretical value and the balance of the payment device 200. Further, the first processing unit 130 transmits an instruction to the second reception unit 120 to receive the balance of the parent device and the balance of the slave device. Thereby, the product registration device 101 executes the processes from step S82 to step S85 described using FIG. 8. That is, the first receiving unit 110 of the product registration device 101 receives the theoretical value and the amount in the payment device 200 (step S82). Further, the second reception unit 120 of the product registration device 101 receives the amount of money of the parent device and the amount of money of the child device (step S83). Then, the first processing unit 130 executes the closing process of the parent device (step S84). In this way, when the determination unit 180 determines that the child device closing process has been executed in all product registration devices 100 different from the determination unit 180, the first reception unit 110, the second reception unit 120, and the first processing unit 130 Step S82, step S83, and step S84 are executed, respectively. After that, the output unit 160 outputs the balance receipt R61 (step S85).

Note that, similarly to the product registration device 100, the output unit 160 of the product registration device 101 may output the inventory amount of the child device when the device itself is a child device.

As described above, since the base unit receives the balance information of all the slave units from the slave units, the base unit executes the closing process of the base unit after all the slave units complete the closing process of the slave units. Therefore, typically, the store clerk who operates the base unit confirms that the closing process for the slave unit has been completed in all other product registration devices 101, and then issues an instruction to execute the closing process for the base unit. Input on the main unit. According to the product registration device 101 according to the present embodiment, since the product registration device 101 itself automatically determines whether it is a master device or a slave device, it is possible to further reduce the time and effort required by the store clerk in the closing process.

(Modified example)
In a modification of the present embodiment, a configuration will be described in which the product registration device 100 described in the second embodiment further includes a determination section. FIG. 11 is a functional block diagram showing an example of the functional configuration of the product registration device 102 in this modification. For convenience of explanation, blocks similar to those described in the second embodiment described above are given the same reference numerals, and the explanation thereof will be omitted. Furthermore, the payment system 2 including the product registration device 102 in this embodiment has the product registration device 102 ( 102-1 and 102-2), and the other configurations are the same, so a description thereof will be omitted.

As shown in FIG. 11, the product registration device 102 in this embodiment includes a first reception section 110, a second reception section 120, a first processing section 130, a second processing section 140, and a display control section 151. , an output section 160, a display section 170, and a determination section 181.

Similar to the determination unit 180 described above, the determination unit 181 determines whether the child unit closing process has been executed in all product registration devices 102 different from the own device (product registration device 102). For example, when the product registration device 102 including the determination portion 181 is the product registration device 102-1, the determination unit 181 determines whether the child unit closing process has been executed in the product registration device 102-2. Note that the method of determination by the determination unit 181 is not particularly limited. The determination unit 181 supplies the determination result to the display control unit 151. Note that the determination unit 181 may store the determination result in a storage unit (not shown) or the like.

The display control unit 151 receives the determination result from the determination unit 181. The display control unit 151 causes the display unit 170 to display a selection screen in which selectable information is changed according to the determination result.

FIG. 12 is a flowchart showing an example of the processing flow of the product registration device 102 in this modification. Note that the same processes as those shown in FIGS. 7, 8, and 10 are given the same reference numerals, and detailed explanation thereof will be omitted.

First, the determination unit 181 determines whether the child device closing process has been executed in all product registration devices 102 different from the own device (product registration device 102) (step S101). If the slave device closing process is not executed in at least one of the product registration devices 102 different from the own device (NO in step S101), the determination unit 181 determines that at least one of the product registration devices 102 different from the own device A determination result indicating that the closing process for the slave unit is not executed in one of the slave units is supplied to the display control unit 151. The display control unit 151 causes the display unit 170 to display a selection screen in which selectable information is changed according to the supplied determination result. Specifically, the display control unit 151 causes the display unit 170 to display a screen (selection screen) that prompts the user to select execution of the child device closing process (step S112).

FIG. 13 shows an example of the selection screen displayed on the display section 170 by the display control section 151 at this time. In the selection screen SS2 shown in FIG. 13, when compared with the selection screen SS1 shown in FIG. The object C132 for "lump payment" that accepts the selection for execution of the closing process is inactive. Here, object C131 being active means that object C131 is in a selectable state. On the other hand, object C132 being inactive means that object C132 cannot be selected. Note that the display manner of the object C131 and the object C132 is not limited to this. For example, the display control unit 151 may display the object C132 in a state where subsequent processing cannot be executed even if the object C132 is selected. In this manner, the display control unit 151 causes the display unit 170 to display a selection screen prompting the store clerk to select the object C131 of “self-register payment” as shown in FIG. The product registration device 102 then performs steps S71 and S72.

In addition, if the slave device closing process is executed in all of the product registration devices 102 different from the own device (YES in step S101), the determination unit 181 determines that all of the product registration devices 102 different from the own device In this step, a determination result indicating that the closing process of the slave device is being executed is supplied to the display control unit 151. The display control unit 151 causes the display unit 170 to display a selection screen in which selectable information is changed according to the supplied determination result. Specifically, the display control unit 151 causes the display unit 170 to display a selection screen that prompts the user to select execution of the closing process of the parent device (step S113). For example, the display control unit 151 causes the display unit 170 to display a selection screen in which the object C131 of “self-register payment” in FIG. 13 is made unselectable, and the object C132 of “collective payment” is selectable. The product registration device 102 then performs the processes from step S81 to step S85.

As described above, the product registration device 102 according to the present modification can also reduce the effort required for the closing process, similarly to the product registration device 100 and the product registration device 101 described above.
