FIG. 6A shows an example of product management information for each producer stored in the storage unit 22 of the management device 2. As shown in the figure, the storage unit 22 stores 1 producer-specific product management information corresponding to 1 producer. The product management information for each producer corresponding to one producer has a structure including the producer information, the product master table for each producer, and the tax rate information for each producer.

Producer information includes predetermined information related to the corresponding producer. FIG. 6B shows an example of producer information. The producer information in the figure includes each area of the producer number, the producer name, the e-mail address, and the address.
In the producer number area, a producer number, which is an identifier uniquely indicating the corresponding producer, is stored. In the producer name area, the name of the corresponding producer is stored. In the e-mail address, the e-mail address of the corresponding producer is stored. The address area stores the address of the corresponding producer. These pieces of information stored in the producer information are based on, for example, the information entered when the producer is registered.

The product master table for each producer is information that tabulates product information for each product registered as being sold at the store ST by the corresponding producer. FIG. 6C shows an example of the product master table for each producer. One row (record) in the product master table for each producer in the figure is product information corresponding to one product. The product information corresponding to one product includes each area of the producer number, the product code, the product name, the price, and the applicable tax rate.
The producer number of the corresponding producer is stored in the producer number area. In the product code area, the product code, which is an identifier given to the corresponding product, is stored. The product name of the corresponding product is stored in the product name area. In the price area, the price set for the corresponding product is stored. In the area of the applicable tax rate, information indicating which of the tax rates 1 to 3 described later is applied to the corresponding product is stored.
These pieces of information can be input by the producer by performing an operation on the management device 2 when performing master registration for registering the product information in the product master table for each producer. It should be noted that the store clerk at the store ST may perform the input operation after receiving the information necessary for master registration from the producer.

The tax rate information for each producer is information indicating one or more tax rates associated with the corresponding producer. In the present embodiment, as an example, the consumption tax system is set to 10%, 8%, and 5%, respectively, as three different tax rates. In this case, the tax rate of 10% is the standard tax rate, and the tax rates of 8% and 5% are the reduced tax rates, respectively. Which of these tax rates is applied to the product is predetermined according to the nature of the product.

FIG. 6D shows an example of the tax rate information for each producer associated with the producer whose producer number is “0001”. The tax rate information by producer in the figure includes the area of the producer number and the set tax rate.
The producer number of the corresponding producer is stored in the producer number area.
In the area of the set tax rate, the tax rate set in association with the corresponding producer among the above three tax rates is stored. In the example of the figure, the area of the set tax rate further includes the area of tax rate 1, tax rate 2, and tax rate 3. The first set tax rate is stored in the area of the tax rate 1. The set second tax rate is stored in the area of the tax rate 2. The set third tax rate is stored in the area of the tax rate 3. In the example of the figure, the tax rate of 10% is stored in the area of tax rate 1, 5% is stored in the area of tax rate 2, and the invalid value is stored in the area of tax rate 3 as "null". Such contents of the figure indicate that two tax rates of 10% and 5% are set corresponding to the producer whose producer number is "0001". That is, as the tax rate set as the tax rate information for each producer, only the tax rate applied to the product sold by the producer among the tax rates of 10%, 8%, and 5% needs to be set.

Such setting of the tax rate in the tax rate information for each producer can be performed at any opportunity by, for example, the producer operating the management device 2. In setting the tax rate in the tax rate information for each producer, the producer performs an operation for declaring the execution of the tax rate setting for each producer to the management device 2. At this time, the producer inputs his / her own producer number. In response to this operation, the management device 2 displays, for example, a producer-specific tax rate setting screen in which a producer-specific tax rate setting operation is performed.
FIG. 7A shows an example of the tax rate setting screen for each producer. On the producer-specific tax rate setting screen of the figure, the input producer number is displayed in the producer number area AR21. Further, in the producer name area AR22, the producer name corresponding to the producer number displayed in the producer number area AR21 is displayed.
In addition, the tax rate setting area AR23 is arranged on the tax rate setting screen for each producer. In the figure, an example in which check boxes are arranged for each tax rate 1 (10%), tax rate 2 (8%), and tax rate 3 (5%) is shown as the tax rate setting area AR23. In this case, the producer selects one or more tax rates applicable to the products he sells from the tax rate 1 (10%), the tax rate 2 (8%), and the tax rate 3 (5%), and the selected tax rate. Operate so that the check box corresponding to is checked. In the figure, the check boxes corresponding to tax rate 2 (8%) and tax rate 3 (5%) are checked, and the check boxes corresponding to tax rate 1 (10%) are unchecked. It is shown. Then, when the producer operates the registration button BT1, the tax rate with the check box checked is registered in the tax rate information for each producer. If the producer wants to cancel the tax rate setting operation, the producer may operate the stop button BT2.
FIG. 7B shows another example of the tax rate setting screen for each producer. In the figure, the same parts as those in FIG. 7A are designated by the same reference numerals, and the description thereof will be omitted.
In the figure, the tax rate designation buttons BT11, BT12, and BT13 are arranged. The tax rate designation buttons BT11, BT12, and BT13 correspond to the tax rate 1 (10%), the tax rate 2 (8%), and the tax rate 3 (5%), respectively. The tax rate designation buttons BT11, BT12, and BT13 switch their states between the active state and the inactive state each time the operation is performed. The active tax rate specification button indicates that the corresponding tax rate is selected, and the inactive tax rate specification button indicates that the corresponding tax rate is not selected.
The producer activates one or more tax rate specification buttons corresponding to each one or more tax rates applied to the products sold by the producer among the tax rate specification buttons BT11, BT12, and BT13, and the tax rate that does not apply to the product. The tax rate specification button corresponding to is inactive. Then, when the producer operates the registration button BT1, the tax rate corresponding to the tax rate designation button that has been in the active state is registered in the tax rate information for each producer.
In addition, although not shown, the tax rate setting screen for each producer has a mode in which the tax rate that the producer wants to use is selected one by one using the pull-down menu, and the numerical value corresponding to the tax rate is displayed by manipulating the number of units. It may be in a mode in which it is directly input.

FIG. 8 is a block diagram showing a configuration example of the label printer 3. The label printer 3 in the figure includes a CPU 31, a storage unit 32, a RAM 33, a display unit 34, an operation unit 25, and a label issuing unit 36.

(C)), the information obtained from the area of the producer number (FIG. 6 (a)) and the price (FIG. 6 (c)).

As described above, when a producer intends to sell a new product, he / she performs master registration in which product information is registered in the product master table for each producer in advance. At the time of master registration, in the present embodiment, when setting the applicable tax rate for the product, the tax rate set in the tax rate information for each producer is presented as an option. Therefore, the producer can select and specify the applicable tax rate of the product from the presented options. As described above, the tax rate set in the tax rate information for each producer is set after only the tax rates that the producer may apply to his / her own products are selected. At the time of master registration, the applicable tax rate will be selected from the tax rate options selected in this way. As a result, it is possible to improve the efficiency of the operation of applying the tax rate to the product in the master registration.

An example of a processing procedure executed by the management device 2 in connection with the master registration of the product will be described with reference to the flowchart of FIG. The master registration operation may be performed by, for example, a clerk who has been informed of information about the product by the producer, but in the following description, the case where the producer performs the operation will be taken as an example.
Step S101: The producer registers the master in advance when there is a new product to be sold at the store ST. Therefore, when performing master registration for his / her product, the producer first performs a master registration declaration operation for declaring master registration to the management device 2. The management device 2 accepts the master registration declaration operation performed by the producer.
Step S102: When the master registration declaration operation is accepted, the management device 2 displays, for example, the producer number input screen on the display unit 24. The producer performs an operation of inputting his / her own producer number on the displayed producer number input screen. The management device 2 acquires the input producer number.

Step S103; When the management device 2 acquires the producer number in step S102, the management device 2 displays the product information registration screen on the display unit 24. The product information registration screen is a screen on which an operation of inputting information items stored in product information for one product is performed. On the product information registration screen, it is possible to input the product name and price corresponding to one product and select the applicable tax rate.
Step S104: Here, an example will be given in which the operations of inputting the product name, inputting the price, and selecting the applicable tax rate on the product information registration screen can be performed in any order. Further, in order to confirm the product information after inputting and selecting these information items and registering the product information in the product master table for each producer, a decision operation (for example, a decision button (or OK) arranged on the product information registration screen) is performed. Take as an example the case where the operation) for the button) is performed.
Therefore, the management device 2 determines what the performed operation is in response to the operation performed on the product information registration screen.
In the following description, "input of information item" includes selecting a parameter from the parameter candidates of the information item such as selection of an applicable tax rate.

Step S105: When it is determined in step S104 that the operation of inputting the product name has been performed, the management device 2 acquires the input product name.
Step S106: Further, the management device 2 generates a product code indicating the product targeted for registration this time according to a predetermined rule. The management device 2 generates a product code based on the producer number input in step S102 and the product name input in step S105. That is, the product code corresponds to the combination of the producer number and the product name. Therefore, even if the product name is the same, the product code will be different if the corresponding producer number is different.
Step S107: When it is determined that the operation for inputting the price has been performed in step S104, the management device 2 acquires the input price.

Step S108: If it is determined in step S104 that the tax rate application operation has been performed, the following processing is executed. As a specific example, the operation of applying the tax rate is an operation of displaying a menu (here, for example, a pull-down menu) in which the options of the applicable tax rate are displayed as a list. Therefore, the management device 2 displays a pull-down menu for selecting the applicable tax rate in response to the operation of applying the tax rate. The set tax rate shown in the producer-specific tax rate information (FIG. 6 (d)) is reflected in each list item of the applicable tax rate displayed in the pull-down menu for selecting the applicable tax rate. That is, a list of tax rates set corresponding to the producer number input in step S102 is displayed. Specifically, as shown in FIG. 6D, when two tax rates of 10% and 5% are stored as the set tax rate, the pull-down menu for selecting the applicable tax rate shows the tax rate of 10%. Two list items are displayed: a list item and a list item with a tax rate of 5%.
Step S109: The producer performs an operation (applicable tax rate selection operation) of selecting a list item of the tax rate to be applied to the product to be registered from the list items of the tax rate displayed in the displayed pull-down menu of the applicable tax rate selection. .. The management device 2 accepts the applicable tax rate selection operation performed by the producer.
Step S110: The management device 2 acquires the tax rate selected by the applicable tax rate selection operation received in step S109 as the applicable tax rate of the product to be registered.

Step S111: When it is determined in step S104 that the determination operation has been performed, the management device 2 generates product information including the contents of the information items acquired by the operation on the product information registration screen so far. The management device 2 registers the generated product information. That is, the management device 2 stores the generated product information to be newly added to the product master table for each producer corresponding to the producer number acquired in step S102. This completes the master registration of one product.
Even if the determination operation is performed without the required information items being input, the operation is invalidated and it cannot be determined that the determination operation has been performed.

Step S112: Further, in response to the determination operation being performed, the management device 2 holds the applicable tax rate selected by the operation on the product information registration screen this time. Then, the process returns to the process of step S103. As a result, the product information registration screen in which information items have been input and selected up to now is deleted, and instead, a new product information registration screen corresponding to the product to be registered next is displayed. On the newly displayed product information registration screen in this way, the applicable tax rate selected on the previous product information registration screen is displayed as it is. That is, under the present embodiment, the applicable tax rate selected in the previous time is retained at the stage when the master registration of the product is newly started.

After any of the processes in steps S106, S107, and S110, the management device 2 returns the process to step S104. As a result, the management device 2 can accept operations for information items that have not yet been input or selected. In addition, the producer can input and reselect the information items once input and selected.
Further, after the processing in step S112, the processing is returned to step S103 as described above. In this case, master registration for the next product can be performed on the product information registration screen newly displayed in step S103. At this time, as described above, as for the applicable tax rate, the tax rate already selected at the time of the previous registration of the product information is retained as it is. Therefore, the producer does not need to perform the operation of selecting the applicable tax rate again when the master registration of the product is performed for the second time or later, if the applicable tax rate is the same as that selected at the time of the master registration of the previous product. As a result, for example, if the producer performs an operation to continuously master-register products having the same applicable tax rate, the operation of selecting the applicable tax rate is not required each time, so that the registration operation can be performed efficiently. Can be done. On the other hand, when changing the applicable tax rate, the producer may display the pull-down menu for selecting the applicable tax rate and select the tax rate.
The operation screen corresponding to the setting of the applicable tax rate on the product information registration screen may be in a mode in which the tax rate selection area AR33 is arranged according to, for example, FIG. 13 described later. Then, for example, on the product information registration screen newly displayed in step S103, the tax rate selected at the time of the previous registration of the product information may be reflected in the tax rate selection area AR33. In addition, the producer information area AR31 is arranged on the product information registration screen, and the producer information area AR31 is also displayed in the producer information area AR31 on the product information registration screen when the previous product information is registered. The same producer information may be displayed.

Further, when the producer completes the master registration for all the products to be newly sold, the producer performs an end operation for terminating the master registration mode. The end operation is, for example, an operation for the end button arranged on the product information registration screen.
When it is determined in step S104 that the end operation has been performed, the POS register 1 ends the master registration mode by ending the process shown in the figure.

Further, when the producer displays and sells the product for which the master registration has been completed as described above at the store ST, the producer operates the label printer 3 to label the label (FIG. 9A) corresponding to the product. It is issued from the printer 3. The producer attaches the issued label to the product and displays it at the store ST.
Further, in the POS system of the present embodiment, it is possible to perform master registration of products by operating not only the management device 2 but also the label printer 3. For example, if the product is about to be sold at the store ST, but the master registration has not been completed yet, the producer can operate the label printer 3 to perform the master registration of the product and the issuance of the label at the same time. ..

An example of a processing procedure executed by the label printer 3 in connection with issuing a label and registering a master of a product will be described with reference to the flowchart of FIG.
Step S201: In starting the operation for issuing the label, the producer performs an operation of inputting his / her own producer number on the label printer 3. The label printer 3 acquires the input producer number.
Step S202: When issuing a label of a product for which master registration has been completed, the producer performs an operation of inputting a product name or a product code of the product to which the label is issued. On the other hand, the producer performs a master registration declaration operation when issuing a label of a product for which master registration has not been completed. Therefore, the label printer 3 first determines whether or not the operation of inputting the product name or the product code has been performed after the operation of inputting the producer number has been performed in response to step S201.
Step S203: Further, when it is determined in step S202 that the operation of inputting the product name or the product code has not been performed, the label printer 3 further determines whether or not the master registration declaration operation has been performed. When it is determined that the master registration declaration operation is not performed, the management device 2 returns the process to step S202.

Step S204: When it is determined in step S202 that the product name or product code has been input, the label printer 3 acquires the product name or product code input by the operation.
Step S205: Next, the label printer 3 acquires the producer name corresponding to the producer number acquired in step S201 and the product information corresponding to the product name or product code acquired in step S204.
For this purpose, the label printer 3 transmits a label information request including the producer number acquired in step S201 and the product name or product code acquired in step S204 to the management device 2. The management device 2 reads the producer name associated with the producer number included in the received label information request from the producer information in the product management information for each producer. Further, the management device 2 obtains product information including the product name or product code included in the received label information request from the product master table for each producer associated with the producer number included in the received label information request. Is read. The management device 2 transmits information including the read producer information and product information to the label printer 3 as label information. The label printer 3 acquires the producer name and the product information by receiving the label information transmitted in this way.

Step S206: When it is determined in step S203 that the master registration declaration operation has been performed, the label printer 3 executes the master registration correspondence process. The label printer 3 may execute, for example, a process according to steps S103 to S111 of FIG. 10 as a master registration-corresponding process. In this case, when the label printer 3 displays the operation screen corresponding to the pull-down menu for selecting the applicable tax rate corresponding to step S108, the label printer 3 associates with the producer number acquired in step S201. Information on the applied tax rate is obtained from the management device 2. The label printer 3 may display the operation screen by using the acquired information on the applicable tax rate. Further, when the label printer 3 performs the product information registration process corresponding to step S111, the label printer 3 transmits a master registration request including the producer number and the product information acquired in step S201 to the management device 2. To do. In response to the reception of the master registration request, the management device 2 is received in the product master table for each producer (FIG. 6 (c)) associated with the producer number included in the received master registration request. The product information included in the master registration request is stored so as to be added.

Further, the label printer 3 holds (stores) the tax rate applied to the product in the master correspondence registration process in step S206. Then, for example, when the label of the next product is issued and the master registration of the product is also performed, the operation screen in which the retained tax rate is selected is displayed. As a result, even when the product master registration is performed by the label printer 3, the operation of selecting the tax rate can be omitted by continuously performing the master registration of the products to which the same tax rate is applied.

Step S207: The label printer 3 performs a process of acquiring the producer name together with the process of supporting master registration in step S206. For this purpose, the label printer 3 requests the management device 2 for the producer name associated with the producer number acquired in step S201. The management device 2 reads the producer name associated with the producer number indicated in the request from the producer information, and transmits the read producer name to the label printer 3.

Step S208: The producer instructs the label issuance after the product name and product code input operation in step S202, or after performing the operation corresponding to the master registration process in step S206 to complete the master registration. Issuance). In the label issuing operation, for example, an operation of designating the number of issued labels can be performed.
The label printer 3 executes the label issuing process in response to the label issuing operation. In the label issuing process, when the process of step S205 is performed, the label printer 3 generates code information including the producer number and product information acquired in step S205. The label printer 3 controls the label issuing unit 36 to print a specified number of labels on paper, and ejects the printed labels one by one. At this time, the label printer 3 prints the producer name, the product name, the price, the bar code corresponding to the generated code information, and the like on the paper as illustrated in FIG. 9A for each label. The label issuing unit 36 is controlled so as to be performed.
Further, when the label printer 3 reaches step S208 through the processes of steps S206 and S207, the label printer 3 uses the product information acquired in step S206 and the producer name acquired in step S207. Execute the label issuance process.

Step S209: When the label issuing process for one product is completed, the label printer 3 determines whether or not the label issuing mode corresponding to the producer number input in step S201 has been terminated. The label issuing mode is terminated, for example, in response to an end operation instructing the termination of the label issuing mode. In the label issuing mode, the label issuing mode may be terminated even when a certain period of time has elapsed without performing either the product name or product code input operation or the master registration declaration operation.
If the producer performs the product name or product code input operation for the next product or the master registration declaration operation within a certain period of time from the previous label issuance, step S208 corresponds to the next product. Processing up to label issuance is performed. On the other hand, if it is determined that the label issuing mode has ended, the label printer 3 ends the operation corresponding to the label issuing by ending the process shown in the figure.

In the POS system of the present embodiment, a label can be issued by a label printer even if the product has forgotten to be registered as a master by the producer due to the specifications. For this reason, a product that has not been registered as a master but has a label attached (a product that has not been registered as a master) may be displayed and sold at the store ST.
In this way, when a customer tries to purchase an unregistered master product and brings it to the POS register 1, it is difficult for the clerk who operates the POS register 1 to notice that the product is not registered as a master. Therefore, the clerk performs an operation of scanning the bar code of the product label by the scanner unit 18 in order to register the master unregistered product brought to the POS register 1 by the customer as a purchased product. However, in this case, the product information of the product indicated by the barcode read from the label is not registered in the producer-specific product master table of the corresponding producer. Therefore, in this case, a product registration error occurs. Even if a product registration error occurs in this way, it is preferable for the store ST, the producer side, and the customer side to be able to sell the unregistered master product to the customer on the spot.
Therefore, in the POS system of the present embodiment, as described below, when the master unregistered product is the target of purchase registration, the master registration of the master unregistered product is performed by operating the POS register 1. It is configured so that accounting processing (processing from purchase registration processing to settlement processing) is possible.

With reference to the flowchart of FIG. 12, an example of the procedure of accounting processing in which the POS register 1 in the present embodiment is executed corresponding to one transaction will be described.
Step S301: The clerk who operates the POS register 1 performs an operation of purchasing and registering the products brought by the customer for accounting one by one. The purchase registration operation is an operation in which the scanner unit 18 reads the bar code of the label attached to the product as described above. The POS register 1 acquires the code information indicated by the read barcode in response to the operation of reading the label barcode by the scanner unit 18. The code information is information corresponding to the barcode format illustrated in FIG. 9B, and includes product code, producer number, and price information.

Step S302: The POS register 1 determines whether or not the product indicated by the code information acquired in step S301, that is, the product to be purchased is registered as a master. For this purpose, the POS register 1 transmits a product information request including the producer number and the product code indicated by the code information acquired in step S301 as a search key to the management device 2. The management device 2 that has received the product information request searches for the product information corresponding to the search key (producer number and product code) included in the received product information request.
When the product information is searched, the management device 2 transmits the searched product information to the POS register 1. On the other hand, when the product information is not searched, the management device 2 transmits a search error notification indicating that there is no product information corresponding to the search key to the POS register 1.
The POS register 1 may determine whether or not the product to be purchased has been registered as a master, depending on whether the response to the product information request is the reception of the product information or the search error notification.
Further, in the case of the label of the product not registered in the master, a significant value may not be stored for the product code in the code information. Therefore, the POS register 1 may determine that the product to be purchased is not registered as a master even when the product code in the code information acquired in step S301 does not have a significant value.

Step S303: When it is determined in step S302 that the product to be purchased is not registered as a master, the POS register 1 determines whether or not there is already a product registered for purchase in this one transaction.

Step S304: There are two types of master registration by the POS register 1 of the present embodiment: regular master registration and simple master registration. The regular master registration is a master registration performed by inputting or selecting all necessary items according to the master registration in the management device 2. The simple master registration is a master registration that is performed simply by inputting or selecting some items necessary to enable proper processing of the current accounting. Therefore, the operation for simple master registration is simpler and can be completed in a shorter time than the master registration.
If it is determined in step S303 that there is no product registered for purchase, that is, if the product subject to this purchase registration is the first product subject to purchase registration in one transaction, the relevant product is applicable. It is considered that the customer can tolerate the waiting time required to perform the operation of regular master registration for the product. That is, if there is no product registered for purchase yet, it can be considered that the master registration may be prioritized.
Therefore, when it is determined that there is no product registered for purchase, the POS register 1 executes the process corresponding to the regular master registration. Specifically, for example, the POS register 1 first causes the display unit 14 with a touch panel, which is a display unit for store clerks, to display an applicable tax rate selection dialog. At this time, the POS register 1 acquires the set tax rate stored in the producer-specific tax rate information corresponding to the producer number included in the code information acquired in step S301 from the management device 2. The POS register 1 displays an applicable tax rate selection dialog in which the acquired set tax rate is selected.

FIG. 13 shows an example of the applicable tax rate selection dialog. In the applicable tax rate selection dialog of the figure, the producer information area AR31, the selling price area AR32, the tax rate selection area AR33, the input button BT21, the registration button BT22, and the cancel button BT23 are arranged.
In the producer information area AR31, information indicating the producer of the product subject to the purchase registration this time is displayed. In the producer information area AR31 of the figure, an example in which the producer number and the producer name are displayed is shown. The information displayed in the producer information area AR31 is included in the barcode code information read according to the product targeted for the purchase registration this time. In the producer information area AR31, either one of the producer number and the producer name may be displayed.
In the selling price area AR32, the price of the product subject to this purchase registration is displayed. The price displayed in the selling price area AR32 is also included in the barcode code information read according to the product targeted for this purchase registration. In addition, for example, when it is necessary to correct the price, the price may be corrected by performing an operation of inputting a numerical value of the price and changing the price displayed in the selling price area AR32.
The tax rate selection area AR33 is an area where the operation of selecting the tax rate applied to the product subject to the purchase registration this time is performed. In the tax rate selection area AR33, the tax rate selection buttons BT31, BT32, and BT33 are arranged. The tax rate selection buttons BT31, BT32, and BT33 correspond to tax rates 1 (10%), tax rates 2 (8%), and tax rates 3 (5%), respectively. In this case, the tax rate set for the product subject to the purchase registration this time is any one of the tax rate 1 (10%), the tax rate 2 (8%), and the tax rate 3 (5%). Therefore, in the tax rate selection buttons BT31, BT32, and BT33, the operated tax rate selection button becomes active and the remaining two tax rate selection buttons are inactive in response to the operation of selecting one of them. It is designed to be. That is, in the tax rate selection area AR33, the tax rate is selectively selected from the tax rate 1 (10%), the tax rate 2 (8%), and the tax rate 3 (5%).

The explanation is returned to FIG.
Step S305: When performing an operation of applying a tax rate to the displayed applicable tax rate selection dialog, the clerk performs an operation on the input button BT21 in the applicable tax rate selection dialog and declares the operation of applying the tax rate.
Then, the clerk selects the tax rate to be applied to the product by operating the tax rate selection button arranged in the tax rate selection area AR33. After that, the clerk performs an operation (applicable tax rate selection operation) on the registration button BT22. The POS register 1 accepts the applicable tax rate selection operation performed in this way.
If the clerk wants to cancel the operation of applying the tax rate and clear the application tax rate selection dialog, the clerk may operate the stop button BT23.

Step S306: When the POS register 1 receives the applicable tax rate selection operation, the POS register 1 displays an information item input screen for inputting other uninput information items related to master registration instead of the applicable tax rate selection dialog. The clerk performs an operation of inputting a parameter for each information item on the information item input screen. The POS register 1 receives an input operation performed on the information item input screen in this way.
It is preferable that the POS register 1 is in a state in which the information items included in the code information acquired in step S301 have already been input when the information item input screen is displayed.

Step S307: When the input operation of the information item corresponding to step S306 is completed, the clerk performs, for example, an input completion operation (for example, an operation on the decision button arranged on the information item input screen). In response to the input completion operation, the POS register 1 executes the regular master registration control. As the regular master registration control, the POS register 1 transmits a regular master registration request including the applicable tax rate selected in accordance with step S305 and the parameters of various information items input in step S306 to the management device 2.
The management device 2 generates product information (genuine product information) including the applicable tax rate included in the received regular master registration request and parameters of various information items, and uses the generated regular product information of the corresponding producer. Store in the master table for each producer. As a result, regular master registration is performed.

Step S308: If a product that has not been registered as a master is subject to purchase registration while there is a product that has already been registered for purchase, a simple master registration is performed rather than a regular master registration for the product that is subject to this purchase registration. It may be more convenient, for example, to shorten the waiting time for customers. However, if the time required for regular master registration is acceptable, it is better to perform master registration.
Therefore, if it is determined in step S303 that there is a product that has already been registered for purchase, the POS register 1 displays the master registration type selection screen and accepts the master registration type selection operation. The master registration type selection screen is an operation in which the clerk selects whether to perform master registration for the product targeted for this purchase registration by either regular master registration or simple master registration (master registration type selection operation). It is an operation screen to perform.

Step S309: When the POS register 1 receives the master registration type selection operation, it determines which master registration type, the regular master registration or the simple master registration, is selected by the master registration type selection operation.
When it is determined that the regular master registration is selected, the POS register 1 shifts to the process of step S304 and executes the process corresponding to the regular master registration.
Step S310: On the other hand, when it is determined in step S309 that the simple master registration is selected, the POS register 1 executes the process for the simple master registration. For this purpose, the POS register 1 first displays the applicable tax rate selection dialog. The process of step S310 may be the same as that of step S304 described above. That is, even when the simple master is registered, the POS register 1 displays the applicable tax rate selection dialog shown in FIG.
Step S311: The POS register 1 accepts the applicable tax rate selection operation performed on the applicable tax rate selection dialog displayed in step S310.

Step S312: When the applicable tax rate selection operation is received in step S311, the POS register 1 performs simple master registration control. That is, the POS register 1 sends a simple master registration request including the information item included in the code information acquired in step S301 and the applicable tax rate selected by the applicable tax rate selection operation received in step S311 to the management device 2. Send.
The management device 2 generates product information (simple product information) including the applicable tax rate included in the received simple master registration request and the parameters of the information items, and the generated simple product information is produced by the corresponding producer. Store in the master table for each person. As a result, simple master registration corresponding to one product is performed.

Step S313: When it is determined in step S302 that the product has been registered as a master, or after the processing of step S307 or the processing of step S312, the POS register 1 is used to purchase the product targeted for purchase this time. Perform registration process.
When it is determined in step S302 that the product has been registered as a master, in step S313, the information items included in the product information acquired from the management device 2 and the acquired code information in the determination in step S302 are added. Based on this, the purchase registration process of the product to be purchased is performed using the producer name acquired from the producer information of the management device 2.
Further, when the process of step S307 is performed, the producer of the management device 2 is based on the code information acquired in step S301, the applicable tax rate obtained in response to step S305, and the acquired code information. The purchase registration process of the product to be purchased is performed using the producer name obtained from the information.
Further, when the process of step S312 is performed, the producer of the management device 2 is based on the code information acquired in step S301, the applicable tax rate obtained in response to step S311 and the acquired code information. The purchase registration process of the product to be purchased is performed using the producer name obtained from the information.

Step S314: Next, the POS register 1 determines whether or not a subtotal operation has been performed. The subtotal operation may be performed as an operation on the subtotal button arranged on the product registration screen displayed on the display unit 14 with the touch panel or the subtotal key included in the key operation unit 15.
When it is determined that the subtotal operation is not performed, the POS register 1 can perform the processing corresponding to the next product to be purchased by returning the processing to step S301.
Step S315: On the other hand, when it is determined that the subtotal operation has been performed, the POS register 1 executes the settlement process based on the settlement information obtained in accordance with the purchase registration process so far. Settlement information includes, for example, product unit information such as the producer name, product code, product name, price (excluding tax), and applicable tax rate for each product for which purchase registration has been made, and tax for the product for which purchase registration has been made. Includes the total amount including tax and tax.
For example, in the case of cash accounting, when the clerk receives the deposit from the customer, inputs the amount, and operates the current total, the change is calculated by the POS register 1, and the drawer 30 is displayed together with the change. Controlled to open. The clerk takes out the amount of change from the drawer and gives it to the customer.
Step S316: Then, when the settlement process is completed as described above, the POS register 1 issues a receipt indicating the contents of the current transaction. In this way, the accounting process corresponding to one transaction by the POS register 1 is executed.

In the above example, if a product that has not been registered as a master is subject to purchase registration in one transaction and there is a product that has already been registered for purchase, the master registration type (regular master registration, simple master registration) is selected. Is being done. However, depending on the operation, if there is a product already registered for purchase, the simple master registration may be uniquely performed without selecting the master registration type. On the contrary, when a product not registered as a master is subject to purchase registration, the master registration type may be selected regardless of whether or not there is a product already registered for purchase. Further, in the price confirmation mode, the master registration type may be selected when the product whose price has been confirmed is not registered.

FIG. 14 shows an example of the receipt issued in step S316. In the purchased product list area AR10 in which the list of purchased products is shown on the receipt of the present embodiment, the items of the purchased products are sorted and printed for each producer. Specifically, in the purchased product list area AR10 in the figure, the products with the producer name "Mr. A" are collectively arranged in the producer-specific product list area AR11, and in the subsequent producer-specific product list area AR12. , The mode in which the products whose producer name is "Mr. B" are arranged together is shown. With such a receipt, it is easy to understand which product was purchased by each producer.
In the purchased product list in the purchased product list area AR10 of the receipt, the items of the purchased products may be printed in the order in which the purchase registration is performed. Further, the order of the items of the purchased products in the purchased product list area AR10 may be switched between the format grouped by producer and the order in which the purchase registration is performed by an operation. Further, the product registered as a regular master or the product registered as a simple master may be printed so as to be identifiable, or may be indicated in an electronic journal.

As described with reference to FIG. 12, the POS register 1 of the present embodiment can perform regular master registration or simple master registration for a product to be purchased and registered that has not been master-registered. Here, since there are information items that have not been input yet for the products for which the simple master registration has been performed, it is preferable to input parameters to the information items that have not been input later to correct the registration to the regular master. Such a modification of the master registration can be performed by a store clerk or a producer on the management device 2 at a timing when time is available, for example.
However, it can be said that it is preferable that the above-mentioned modification of the master registration is performed at the earliest possible timing. Therefore, in the present embodiment, the operation for modifying the master registration from the simple master registration to the regular master registration can be performed at the timing when the POS register 1 is in the standby state. This point will be described below.

The flowchart of FIG. 15 shows an example of a processing procedure executed by the POS register 1 of the present embodiment in connection with the modification of the master registration from the simple master registration to the regular master registration.
Step S401: The POS register 1 determines whether or not a certain time has elapsed since the accounting process corresponding to one transaction was completed and the standby state was started. When it is determined that a certain time has elapsed since the standby state was started, the POS register 1 shifts to the following processing related to master registration modification.
It should be noted that, as soon as the standby state is started, the process may be shifted to the process related to the master registration correction. However, in this case, for example, in a situation where there are many customers waiting for accounting, the registration correction dialog described later is immediately displayed every time the accounting corresponding to one transaction is completed, which causes trouble for the clerk. You will remember. Therefore, if the registration correction dialog is displayed after a certain period of time has passed from the start of the standby state, the clerk will not be bothered.

Step S402: Next, the POS register 1 determines whether or not the simple product information, that is, the product information in the state of being registered in the simple master is stored in the management device 2. For this purpose, the POS register 1 transmits an inquiry (simple product information inquiry) regarding the presence or absence of simple product information to the management device 2.
The management device 2 searches the product master table for each producer corresponding to each producer in response to the reception of the simple product information inquiry, and determines the presence or absence of the simple product information. Whether or not the product information is simple product information can be determined by whether or not there is any information item included in the product information that does not store significant information. Alternatively, the management device 2 may set a flag indicating that in the simple product information and then determine by the presence or absence of the flag.
As a response to the simple product information inquiry, the management device 2 transmits information indicating whether or not the simple product information is available to the POS register 1. The POS register 1 can determine whether or not there is simple product information based on the response received from the management device 2.
If it is determined that there is no simple product information, the processing shown in the figure is terminated.

Step S403: When the POS register 1 determines that there is simple product information, the registration correction dialog is displayed on the display unit 14 with a touch panel. Although not shown in the registration correction dialog, a clerk requesting confirmation that the simple product information remains and whether or not to perform the master registration correction operation for correcting the simple product information to the regular product information from now on. Message is displayed. Further, in the registration correction dialog, buttons (for example, "Yes" button and "No" button) for specifying whether or not to perform master registration correction are arranged.
If the clerk determines that the POS register 1 can afford to perform the master registration correction operation in the current situation, the operation for specifying the master registration correction in the registration correction dialog (correction declaration operation). : For example, perform an operation on the "Yes" button). On the other hand, when the clerk determines that there is no room to perform the master registration correction operation on the POS register 1 in the current situation, an operation of specifying not to perform the master registration correction in the registration correction dialog (for example, Perform the operation for the "No" button in the registration modification dialog).

Step S404: The POS register 1 determines whether or not the correction declaration operation has been performed while the registration correction dialog is displayed in step S403. If the correction declaration operation is not performed and the operation for specifying that the master registration correction is not performed is performed, the process shown in the figure is terminated.

Step S405: On the other hand, when the modification declaration operation is performed, the POS register 1 shifts to the process for master registration modification. As a process for correcting the master registration, first, the POS register 1 acquires one simple product information from the management device 2. In order to acquire the simple product information, the POS register 1 transmits a simple product information request to the management device 2, and receives one simple product information transmitted as a response from the management device 2. In this way, the simple product information is acquired by the POS register 1.

Step S406: The POS register 1 displays an information item input screen that reflects the contents of the simple product information acquired in step S405. On the displayed information item input screen, information has already been input for the information item for which significant information has been stored in the corresponding simple product information, and significant information is stored in the corresponding simple product information. Information items that have not been entered are not entered.
Step S407: The clerk performs an operation of inputting information for an uninput information item on the information item input screen displayed in step S406. The POS register 1 accepts the operation. When the clerk completes the operation of inputting information for the uninput information item, the clerk performs an operation on the enter button on the information item input screen, for example.

Step S408: In the POS register 1, the simple product information acquired in step S405 is updated to the regular product information in the management device 2 in response to the operation for the enter button on the information item input screen. To control. At the stage when the operation for the enter button on the information item input screen is performed, significant information is stored in the POS register 1 for all the information items included in the product information. Therefore, the POS register 1 transmits a product information update request including such information to the management device 2. The management device 2 stores the information of the information item that has not been stored in the corresponding simple product information according to the information included in the product information update request, and performs a process of updating to the regular product information.

Step S409: The POS register 1 determines whether or not the master registration modification process that has been executed so far should be terminated. For example, the POS register 1 makes an inquiry to the management device 2 as to whether or not the simple product information still remains, and if a response is obtained from the management device 2 that the simple product information does not remain, the master It can be determined that the registration modification process should be completed. On the other hand, if a response is obtained from the management device 2 that the simple product information remains, it can be determined that the master registration correction process should not be completed.
Further, even if the simple product information remains in the management device 2, the clerk instructs the end of the master registration correction when, for example, the customer comes to the POS register 1 for accounting. The end instruction operation may be performed to perform the purchase registration operation of the product. The POS register 1 determines that the process of master registration modification should be terminated when the end instruction operation for instructing the termination of the master registration modification of the clerk is performed.
If it is determined that the master registration modification process should not be completed, the POS register 1 returns the process to step S405. As a result, the POS register 1 can acquire the following simple product information from the management device 2 and modify it to the regular product information.
On the other hand, when it is determined that the master registration modification process should be completed, the POS register 1 ends the process shown in the figure. Further, the POS register 1 may communicate between the management device and the POS cash register when it is not operated for a certain period of time or longer, and display a registration correction dialog when there is simple product information.

In addition, under this embodiment, point information defined for points to be given to a customer in response to a purchase of a product or the like can be set by operating the management device 2 or the POS register 1 in correspondence with the producer. May be. The point information includes information indicating the product to be given points and the number of points to be given. Such point information may be managed so as to be further included in the product management information for each producer (FIG. 6A).
Further, the discount information regarding the discount (discount) of the product may be set according to the producer by operating the management device 2 or the POS register 1. The discount information can include information such as the product to which the discount is applied, the period and time zone to which the discount is applied. Such discount information may also be managed so as to be further included in the product management information for each producer (FIG. 6A).
By setting point information and discount information in this way, not only tax rates but also information such as points and discounts can be set according to the producer. In other words, the information related to the product can be set in detail and in various ways according to the producer.

<Summary of Embodiment>
(1) As described above, one aspect of the present embodiment is associated with each producer number (an example of seller identification information) indicating a producer (an example of a seller) who sells a product, and described above. It is a product sales data processing device including a product information management means for managing product information related to a product sold by a seller and a tax rate setting means for setting a tax rate of 1 or more corresponding to each producer number.
Here, the product sales data processing device in the present embodiment may correspond to the POS register 1 and the label printer 3 in addition to the management device 2. That is, in the description of the above embodiment, the tax rate in the tax rate information for each producer is set according to the operation of the management device 2. However, in correspondence with the configuration of (1), the tax rate may be set in the tax rate information for each producer by operating the POS register 1 or the label printer 3.
According to the above configuration, it is possible to set a tax rate of 1 or more corresponding to each producer number.
