Description

  The present invention relates to a POS register.

  The POS register is widely used in supermarkets or convenience stores. In Patent Document 1, in an POS register that can temporarily hold an operation for a customer (current customer) that is currently supported and can perform an interrupt registration process for a product that the next customer (next customer) purchases, A method has been proposed in which the current customer's payment is processed, and at the same time, the interruption registration processing of the product purchased by the next customer can be continued.

  In the POS register of Patent Document 1, when the product registration process of the current customer or the accounting process of the registered product is temporarily suspended and the registration process or accounting process of the product purchased by the next customer is performed, the current customer who is temporarily suspended When a customer who has been temporarily suspended is processed again after that, the operator operates the number assigned at the time of temporary suspension or the hold key corresponding to this number, so that the current It reads out registration data during customer processing, and registers or accounts for additional products.

JP-A-5-54258

  However, in the technique disclosed in Patent Document 1, the operator stores the current customer in association with the number assigned to the current customer process temporarily held, and executes the current customer process temporarily held again. In this case, the operator confirms the current customer, inputs and designates or selects the number stored in association with the current customer, and calls the registered data during the processing of the current customer temporarily held. For this reason, there is a problem that the operator calls the purchase information of another customer by mistake and performs additional registration processing and accounting processing of the product on the registration data of the other customer. In addition, if the operator makes such a mistake, it is necessary to correct the registration of the product, so the accounting cannot be performed smoothly, and the customer before the cash register is busy with the accounting process. The problem which will do also occurs.

  Moreover, in what is shown by the above-mentioned patent document 1, an operator memorize | stores all the correspondence with a customer and a holding | maintenance key based on the correlation with the number given at the time of the processing of the customer who was temporarily held and the customer temporarily. Therefore, it cannot be applied to a POS register that performs registration processing of products purchased by three or more customers.

  In view of the above-described problems, an object of the present invention is to provide a POS register that can prevent an operator from performing additional product registration processing or accounting processing on registration data of another customer. To do.

The present invention stores transaction information of a plurality of customers who have not completed accounting from registration of products purchased by the customer, and is registered by the registration processing in a POS register capable of performing registration processing or accounting processing in parallel. a transaction storage means for storing purchase information about the customer's product, which is for each of the customers, response and purchase information of the customer in the transaction during the registration processing storage means stores or in accounting, the purchase information for each of the customer and an index to be displayed is switched attach, accounting of the and to that trading display means displays the identification information identifying the customer, purchase information and the corresponding index of the customer the transaction display means displays on the index If the process has not been completed, alternatively it accepts the selection of the index of the customer in the registration process or during the accounting process, the selection In the POS register, characterized in that comprising a display switching means for the purchased information Ru is displayed on the transaction display means in said registration process or during the accounting corresponding to the index of the customers to which the selected and put only is there.

According to this configuration, transaction storage means in a POS register that can store transaction information of a plurality of customers who have not completed accounting from registration of a product purchased by a customer and can perform registration processing or accounting processing in parallel. Stores, for each customer, purchase information related to the customer's product registered by the registration process. Further, the transaction display means stores the purchase information of the customer in the registration process or the accounting process stored in the transaction storage means, an index for switching and displaying the purchase information in association with each customer, and the index Identification information for identifying the customer is displayed. In addition, the display switching means may selectively select the customer index during the registration process or the accounting process when the accounting process of the purchase information corresponding to the customer index displayed by the transaction display means is not completed. reception, Ru display the purchase information of the registration process or during in accounting corresponding to the index of the customers that are the selected accepts the selection transaction display unit.

  This eliminates the need for the operator to perform an operation (manual operation) for causing the transaction display device to display the purchase information of the customer who will perform the registration process or accounting process next time. Thus, it is possible to prevent the accounting process from being performed and the registration of additional products due to wrong purchase information of other customers.

In the POS register of the present invention, the display switching means should be executed next when the transaction storage means stores the accounting information of the purchase information corresponding to the customer index displayed by the transaction display means. Purchasing information during the registration process or during the accounting process corresponding to an index of a customer who has not completed the registration process or the accounting process is displayed on the transaction display means.
Further, in the POS register of the present invention, before Symbol display switching means, when accounting for the purchase information of the customer the transaction display means is displaying has been completed, the index associates the purchase information of the customer Based on the direction in which the customer leaves the POS register after the customer has finished accounting, the index upstream from the POS register in the direction away from the POS register is associated with the index. The purchase information for each customer is sequentially displayed from the index from which the association is deleted.

According to this arrangement, table示切exchange means, when accounting for purchase information of the customer transaction display means is displaying is completed, erases the correspondence of purchase information of the customer from the index, customer accounting Based on the direction of leaving the POS register after completing the processing, the index upstream from the POS register with respect to the index from which the association has been deleted is associated with the purchase information for each customer associated with the index. The index is displayed in order from the deleted index.

  As a result, even if a customer who has completed accounting processing leaves the POS register and other customers who are waiting for accounting processing move sequentially to the vacant area for accounting processing, the contents displayed in the index will be moved Since the customer moves in the same direction as the customer, the order of the customers always corresponds to the display order of the indexes. Therefore, it is possible to prevent the purchase information of another customer from being called in error and performing the accounting process, or the product being additionally registered by mistake in the purchase information of another customer.

Further, in the POS register of the present invention, the display switching means, the information identifying the customer when associating purchase information of the customer to the index, the number of indices for identifying the customer than the number of the purchased information When there are many, the index which cannot be matched with the purchase information is displayed in an empty state.

According to this configuration, when associating the purchase information of the customer with the information specifying the customer as the index, the display switching unit may associate the purchase information when the number of indexes specifying the customer is larger than the number of purchase information. The index that cannot be displayed is displayed in an empty state.

  This makes it easy for the operator to associate a new customer who has entered the accounting column with an empty index, so the index displayed in the empty state is selected, registered, and then registered. It is possible to smoothly perform registration processing or accounting processing of a product to be purchased by a customer who performs processing or accounting processing.

  According to the present invention, when the customer's accounting is completed, the purchase information is sequentially switched and displayed, so that the operator performs additional registration processing and accounting processing of the product on the registration data of other customers. Can be prevented.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic view showing the appearance of a POS register in the present embodiment. FIG. 1A is a top view of a POS (Point Of Sales) register 1. FIG. 1B is a front view of the POS register 1. The POS register 1 includes a checkout counter 60. The checkout counter 60 includes separable tables 60a, 60b, 60c, and 60d. Note that the checkout counter 60 may be composed of one table, and the form of the separation section is not limited to the above.

  The table 60a is a table on which a bag that stores products before product registration is placed. The table 60d is a table on which a bag that stores products after product registration is placed. In the table 60b, the scanner 10 and the POS terminal 2 are installed so as to secure an area where a heel can be placed on the front side. Moreover, the change machine 70 and the drawer 80 are accommodated in the accommodating part of the table 60b. In the table 60c, an area where a bag can be placed on the front side is secured, and the settlement apparatus 3 is installed so as to be movable at least in the right and left in the drawing. The terminal device 2 is connected to the scanner 10, the change machine 70, the drawer 80, and the payment device 3.

  It is assumed that the operator (store clerk) S stands at a position where the terminal device 2 and the scanner 10 can be operated on the front side of the tables 60b and 60c. The customers C1, C2, and C3 stand on the side facing the operator S across the tables 60b and 60c. It is assumed that the queue waiting for the accounting process starts with the customer C1 and is arranged in the order of C2 and C3.

  The terminal device 2 includes a display unit 20 with a touch panel, a key operation unit 30, a first customer display unit 40, and a printing unit 50. FIG. 2 is a perspective view showing the appearance of the terminal device 2. FIG. 2A is a perspective view of the terminal device 2 from the operator S side. FIG. 2B is a perspective view of the terminal device 2 from the customer C1 side. As is apparent from these two figures, each part of the terminal device 2 is integrally combined.

  The payment apparatus 3 includes a second customer display unit 90, a cash table 100, and an electronic money reader / writer 110. FIG. 3 is a perspective view showing the appearance of the settlement apparatus 3. This figure is the figure which looked at the payment apparatus 3 from the customer C1 side. As shown in this figure, the second customer display unit 90, the money table 100, and the electronic money reader / writer 110 of the payment apparatus 3 are attached to the support table 3a.

  In the above example, the operator S is operated by one person operated by one person. However, the POS register 1 is used for two-person operation in which the product registration process and the accounting process are performed by different operators. Is also supported.

  FIG. 4 is a block diagram showing an electrical configuration of the POS register 1. In this figure, blocks corresponding to the configuration shown in FIG. The control unit 410 (display switching means) includes a CPU (Central Processing Unit) and controls each unit shown in the figure. The hard disk 430 stores a control program executed by the control unit 410, a product file, and the like. This product file is a file formed by associating product information such as a product name and sales price with a product code. The RAM 420 (transaction storage means) is a memory in which a control program and a work area that are read from the hard disk 430 and executed by the CPU of the control unit 410 are developed. Details of this work area will be described later. Further, the product file data stored in the hard disk 430 is read and expanded in the RAM 420 by executing the control program. The communication unit 440 performs communication by being connected to an external computer.

  In the scanner 10, when a barcode attached to a product is held over a barcode reading unit (not shown), the barcode reading unit scans the barcode and transmits the product code to the reading control unit 410. The key operation unit 30 is a keyboard-type input means operated by the operator S, and keys used in merchandise registration work and accounting work such as a numeric keypad, a subtotal button, and a current total button are provided. A key operation signal corresponding to the key operation is transmitted from the key operation unit 30 to the control unit 410. The display unit with a touch panel 20 (transaction display means) is a display device provided with a touch panel for the operator S to operate. From the display unit with a touch panel 20, a touch panel operation signal corresponding to the touch operation is transmitted to the control unit 410.

  The control unit 410 displays a GUI operation screen for causing the operator S to perform a touch operation on the display unit 20 with a touch panel. Then, when the product code transmitted from the scanner 10 is received, the control unit 410 reads product information associated with the product code from the product file based on the product code and stores it in the work area of the RAM 420. The control unit 410 receives the touch panel operation signal transmitted from the display unit 20 with a touch panel and the key operation signal transmitted from the key operation unit 30, and stores the predetermined information based on these operation signals and the work area. The merchandise registration process and the accounting process are selectively executed based on the purchased purchase details information. Details of the merchandise registration process and the accounting process will be described later.

  The first customer display unit 40 displays product-specific accounting information for each product under the control of the control unit 410. Specifically, the first customer display unit 40 displays, for example, the product name, the selling price, and the number of each product as product-specific accounting information. The printing unit 50 prints a receipt when the current total button of the key operation unit 30 is pressed. The change machine 70 discharges the change of the amount calculated by the control unit 410 based on the total purchase amount of the entire transaction for the customer calculated by the merchandise registration process and the amount of the deposit deposited from the customer. The drawer 80 is a storage unit that stores banknotes and money.

  Under the control of the control unit 410, the second customer display unit 90 displays the total purchase amount for the customer, the amount of deposits from the customer, and the amount of change. The electronic money reader / writer 110 is used in response to a request for electronic payment from a customer with an electronic money compatible card or a portable terminal having an electronic money function (hereinafter abbreviated as an electronic money compatible card or the like). When the electronic money reader / writer 110 is used, the control unit 410 controls the electronic money reader / writer 110 so that an electronic money compatible card or the like can be received based on the operation of the key operation unit 30. When an electronic money-compatible card or the like is used, settlement processing is performed using the total purchase amount as the payment amount.

  FIG. 5 is a diagram showing a memory map of the RAM 420. As shown in the figure, a work area having a data structure indicated by a memory map 600 is expanded in the RAM 420. This work area includes customer areas 610, 620, 630 and a call pointer 640 for selecting one of these customer areas 610, 620, 630. In customer areas 610, 620, and 630, for each customer, information such as the name and number of items purchased by the customer, the total amount of purchase, and the number of entries are stored. The call pointer 640 stores an address indicating the storage position of each customer area 610, 620, 630.

  6 and 7 are diagrams schematically showing a GUI operation screen 500 displayed by the display unit 20 with a touch panel. As shown in FIG. 6, the GUI operation screen 500 has a structure in which a customer information screen 501a, a customer information screen 501b, and a customer information screen 501c are stacked. In the illustrated example, the customer information screen 501a It is displayed on the top surface. The purchase information displayed on the customer information screens 501a to 501c is based on the information in the customer areas 610, 620, and 630 of the RAM 420. In the lower part of each customer information screen 501a to 501c, indexes 540a to 540c for selecting purchase information of each customer are provided.

  FIG. 7A shows a customer information screen 501a. FIG. 7B shows a customer information screen 501b. FIG. 7C shows a customer information screen 501c. As shown in FIGS. 7A to 7C, each customer information screen 501a to 501c includes a preset key area 510, a purchase details area 520, and a transaction information area 530. In the accounting information area 530, the item name area 531 for displaying the item name included in the latest item-specific accounting information among the item-by-item purchase information registered for purchase details, and the amount for displaying the selling price of the item An area 532, a number area 533 for displaying the number of customers purchased, a total amount area 534 for displaying the total purchase amount of the entire transaction for the customer, a key operation of the key operation unit 30, or a preset key area 510 When the customer's deposit amount is input by the touch operation, a numeric area 535 for displaying the amount is included.

  Next, the product registration process and the accounting process in this embodiment will be described. As shown in FIG. 1, it is assumed that the customer C1 is arranged at the head of the queue waiting for transaction processing, and is arranged in the order of C2 and C3.

  When the customer C1 performs payment, the customer C1 places a bag containing the purchased product on the table 60a. The operator S takes out the product that the customer C1 wants to purchase from the bag, holds the scanner 10 over the barcode attached to the product, and performs product registration processing. The product registration process may use a touch panel or a keyboard. When the product registration is performed, the first customer display unit 40 displays purchase information such as a product name, a selling price, and a number for each product. When the registration process for all the commodities is completed, the operator S presses the subtotal button of the key operation unit 30. When the subtotal button is pressed, the total price of the registered products is displayed from the first customer display unit 40 to the second customer display unit 90.

  When the registration process is completed, the operator S places a bag containing the registered product of the customer C1 on the table 60d, presents the total amount to the customer C1, and waits for the customer C1 to prepare cash. The customer C1 prepares cash according to the total amount presented. If the customer C1 can prepare cash, the operator S deposits cash from the customer C1, inputs the deposit to the key operation unit 30, and presses a current button on the key operation unit 30. When the current total button is pressed, the change is calculated and the change is displayed on the second customer display unit 90. Further, the change is discharged from the change machine 70 and a receipt is printed from the printing unit 50. The operator S stores the cash deposited from the customer C1 in the drawer 80, passes the change and receipt to the customer C1, and ends the accounting process.

  The above-described operation is a case where registration processing and accounting processing are performed smoothly. However, registration processing and accounting processing are not always performed smoothly. For example, it is assumed that the customer C1 notices a product that he or she has forgotten to buy, and goes to the store for the product. Further, for example, it is assumed that the customer C1 takes time to search for cash from the wallet when performing the accounting process for the customer C1. In such a case, if the registration process and accounting process of the customer C1 can be switched to the registration process of the product to be purchased by the next customer C2 (next customer), the registration process and accounting process can be efficiently performed. It can be carried out.

  In this embodiment, in such a case, the customer C2 registration information is transferred from the purchase information of the customer C1 temporarily stored in the RAM 420. When the registration process and the accounting process of the customer C2 are completed, the purchase information of the customer C1 that is temporarily stored automatically is displayed on the GUI operation screen 500 in order to resume the registration process and the accounting process of the customer C1.

  The purchase information is stored in the customer areas 610, 620, and 630 of the RAM 420 as shown in FIG. Then, when the accounting process of the next customer C2 is completed, if the purchase information of the customer for which the registration process or the accounting process has not been completed (in this case, the customer C1) is in the RAM 420, the registration process or the accounting process is performed. The purchase information of the customer that has not been completed is displayed on the GUI operation screen 500 displayed on the display unit 20 with a touch panel.

  FIG. 8 is a diagram showing a display example of the GUI operation screen 500 displayed by the display unit with a touch panel. For example, when performing the accounting process for the customer C1, as shown in FIG. 8A, the purchase information of the customer C1 associated with the index 540a is displayed on the GUI operation screen 500. Further, when the registration process for the next customer C2 is performed during the accounting process for the customer C1, the purchase information of the customer C2 associated with the index 540b is displayed on the GUI operation screen 500 as shown in FIG. 8B. . When the registration process for the customer C2 is completed, as shown in FIG. 8C, the display is automatically switched to display the purchase information of the customer C1 waiting for the accounting process associated with the index 540a. Since the registration process and the accounting process of the customer C2 have been completed, the registration information of the customer C3 is displayed on the index 540b (customer information screen 501b), and nothing is displayed on the index 540c (customer information screen 501c). . Further, the control unit 410 controls the display unit with a touch panel 20 to display purchase information and indexes 540a to 540c.

  As described above, in this embodiment, when the accounting process of the product purchased by a certain customer is switched to the registration process and accounting process of the product that the subsequent customer purchases, and the accounting process of the subsequent customer is completed, The purchase information of the customer whose accounting process is switched is automatically displayed without the operator S performing a special operation. Therefore, the operator S does not need to perform an operation (manual operation) for causing the transaction display device to display the purchase information of the customer who will perform the next accounting process. Or additional registration of products due to mistakes in purchase information of other customers can be prevented.

  In addition, since purchase information of accounting processing switched during accounting is preferentially displayed on the transaction display means, it is possible to preferentially deal with customers waiting for accounting processing, so accounting processing is smooth. It is possible to reduce the congestion of customers waiting for the accounting process in front of the cash register.

  Also, as shown in FIG. 6, in the first embodiment of the present invention, the GUI operation screen 500 displayed on the display unit 20 with a touch panel includes a customer information screen 501a, a customer information screen 501b, and a customer information screen. In the lower part of each customer information screen 501a to 501c, indexes 540a to 540c for selecting purchase information of each customer are provided. The arrangement order of the indexes 540a to 540c is associated with the exit direction in order from the head of the customer waiting for the accounting process. The directions of the indexes 540a, 540b, and 540c can be set by an exit direction flag indicating the exit direction. Further, the program may have a direction in which the customer leaves the POS register without being limited to the exit direction flag.

  FIG. 9 is a diagram showing the relationship between the accounting flow and the arrangement of the indexes 540a to 540c. For example, it is assumed that the customer C1, C2, and C3 are waiting for the accounting process in this order. FIG. 9A shows an example in which customer C1 is in accounting, customer C2 is waiting for accounting processing, and customer C3 is in product registration processing. In this case, as shown in FIG. 9C, the GUI operation screen 500 is displayed on the index 540a to 540a so that the order of the customers C1, C2, and C3 waiting for the accounting process and the order of the indexes 540a, 540b, and 540c are associated with each other. 540c is displayed.

  Here, when the accounting process of the customer C1 ends, as shown in FIG. 9B, the customer C1 leaves the queue waiting for the accounting process, and the customer C2 becomes the head of the queue waiting for the accounting process. Correspondingly, as shown in FIG. 9D, the GUI operation screen 500 displays the index 540a so that the purchase information of the customer C2 to be the head of the accounting processing queue is displayed next to the index 540a. Then, the index 540b is displayed so that the purchase information of the customer C3 is displayed in the index 540b. That is, when there is a customer who has finished accounting for the product, an index associated with the customer who has finished accounting for the product is associated with the customer in the next order based on the direction A1 indicated by the exit direction flag. The index associated with the subsequent customers is shifted in order. Customer C4 has not yet been accounted for and there is no information associated with index 540c, so index 540c is empty.

  As described above, even if the customer C1 who has completed the accounting process leaves the POS register 1 and the customers C2 and C3 waiting for the accounting process sequentially move forward, they are associated with the indexes 540a to 540c in the same direction as the moved customer. Since the arrangement of customers changes, the operator S does not mistake the association between the customers and the indexes 540a to 540c (customer information screens 501a to 501c) for displaying customer information. Therefore, it is possible to prevent the operator S from calling up the purchase information of another customer by mistake and performing additional registration processing and accounting processing of the product.

  Next, the product registration process and the accounting process in this embodiment will be described with reference to the flowchart of FIG. FIG. 10 is a flowchart showing the procedure of the merchandise registration process and the accounting process.

  First, an initial screen is displayed on the GUI operation screen 500 of the display unit 20 with a touch panel (step S301). In the product registration process, the operator S performs an operation of reading the barcode attached to the product that the customer intends to purchase with the scanner 10. The control unit 410 reads the product code indicated by this barcode (step S302). When the product code is read, the control unit 410 searches the hard disk 430 for product information such as a product name and a sales price stored in association with the product code, and displays the product information on the GUI operation screen 500 (step S303). And the control part 410 registers purchase goods (step S304). When the purchased product is registered in step S304, the control unit 410 determines whether or not the subtotal button in the key operation unit 30 has been pressed (step S305).

  When the registration of the product that the customer wants to purchase is completed, the operator S presses the subtotal button. Then, the deposit amount is input, and the current total button is pressed to perform the accounting process.

  If it is determined in step S305 that the subtotal button has been pressed (Yes in step S305), the control unit 410 displays the total purchase amount on the first customer display unit 40 and the second customer display unit 90 (step S305). S306). Then, control unit 410 registers the deposit amount (step S307). Thereafter, the control unit 410 determines whether or not the current total button has been pressed (step S308).

  If the customer can prepare the purchase price, the operator S presses the current total button. If it is determined in step S308 that the current total button has been pressed (Yes in step S308), the control unit 410 causes the printing unit 50 to print a receipt (step S309). Then, the operator S receives the price, processes the change, and gives the change and receipt to the customer. When the accounting process ends in this way, the control unit 410 stores the accounted information (step S310), and proceeds to step S314.

  As described above, the normal product registration process and accounting process are performed by reading the product code and performing the registration process (steps S302 to S304). When the registration process is completed, the subtotal button is pressed to give the amount of money to the customer. Presenting (steps S305 to S307), pressing the cash total button, receiving the price, processing the change, and giving the receipt to the customer (steps S308 to S309) completes the accounting process.

  However, when a product registration process is performed, for example, a customer may go to a sales floor for a product forgotten to buy. In such a case, the operator S switches from the registration process of the product of the customer who went to the sales floor to the registration process of the product to be purchased by the next customer.

  Hereinafter, a procedure for switching from registration processing of a product purchased by a certain customer to registration processing of a product purchased by the next customer will be described. When switching from the product registration process to the product registration process to be purchased by the next customer, the operator S does not press the subtotal button in step S305. If it is determined in step S305 that the subtotal button has not been pressed, the control unit 410 determines in step S311 whether to add or correct the purchased product. If there is an addition or correction of the purchased product (Yes in step S311), an addition or correction process is performed (step S312), and the process returns to step S302. In step S311, if there is no addition or correction of purchased products (No in step S311), the purchase information is switched (step S313), and the process proceeds to step S314.

  Further, when performing the accounting process, for example, there are cases where the customer is taking time to pay for it from the wallet. Even in such a case, the operator S switches from the customer accounting process that is taking time to pay for the product to the registration process for the product that the next customer purchases.

  Hereinafter, a procedure in the case of switching from the accounting process of a certain customer to the registration process of the product that the next customer purchases will be described. When switching from the accounting process of a certain customer to the registration process of the product to be purchased by the next customer, the operator S does not press the current total button in step S308. If it is determined in step S308 that the current total button has not been pressed (No in step S308), the control unit 410 determines in step S311 whether to add or correct the purchased product. And when it determines with not adding and correcting purchase goods (No of step S311), switching of purchase information is performed at step S313, and it progresses to step S314. The purchase information can be switched by the operator S touching the portion of the indexes 540a to 540c corresponding to the customer.

  In step S <b> 314, the control unit 410 determines whether or not the RAM 420 has purchase information of a customer who has not been paid. When it is determined that there is purchase information of a customer who has not been accounted for (Yes in Step S314), the control unit 410 reorganizes the indexes 540a to 540c as described with reference to FIG. 9 (Step S315). Then, the control unit 410 redisplays the indexes 540a to 540c on the GUI operation screen 500 (step S316). Then, the control unit 410 determines whether there is a customer waiting for transaction processing (step S317).

  In step S317, when there is a customer waiting for the accounting process (Yes in step S317), the purchase information of the customer waiting for the accounting process is displayed (step S318), and the process returns to step S306.

  In step S317, if there is no customer waiting for the accounting process (No in step S317), information on the purchased product of the customer being registered is displayed (step S319), and the process returns to step S302.

  If it is determined in step S314 that there is no purchase information for a customer who has not been accounted for (No in step S314), it is determined whether or not the business has ended (step S320). If the business is not finished (No in step S320), the process returns to step S301. If the work is finished (Yes in step S320), the work is finished.

  In the above-described embodiment, when there is no purchase information associated with the indexes 540a to 540c, the indexes 540a to 540c with no associated purchase information are emptied. However, the present invention is not limited to this, and is illustrated in FIG. As described above, the index 540c for which there is no purchase information to be associated may be in a non-visible state (a state in which it is not displayed on the GUI operation screen 500).

  FIG. 11 is a diagram illustrating a display example of indexes 540a to 540c. In FIG. 11A, the purchase information of the customer C1 is associated with the index 540a, the purchase information of the customer C2 is associated with the index 540b, and the purchase information of the customer C3 is associated with the index 540c. The example of a display of the index 540a-540c when attached is shown.

  FIG. 11B shows a display example of indexes 540a to 540c when the registration process and the accounting process of the customer C1 are completed. In this case, the purchase information of the customer C2 and the index 540a are associated with each other, and the purchase information of the customer C3 and the index 540b are associated with each other. Since there is no purchase information associated with the index 540c, the index 540c is invisible.

  Note that the index 540c is merely invisible, and when the operator S touches the position of the invisible index 540c with a finger, the index 540c becomes visible as shown in FIG. FIG. 11B shows a display example of the indexes 540a to 540c when the operator S touches the position of the invisible index 540c with a finger. In this case, the purchase information of the customer C2 and the index 540a are associated with each other, and the purchase information of the customer C3 and the index 540b are associated with each other. Since there is no purchase information associated with the index 540c, the index 540c is displayed as an empty state.

  As a result, since the indexes 540a to 540c that are not related to registration / operation or accounting are not displayed on the GUI operation screen 500, the operator S does not make an erroneous selection, and it is possible to reduce erroneous operations of the operator S.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to the above, and various design changes and the like can be made without departing from the scope of the present invention. Is possible.
