[data structure]
Next, the data structures of the PLU file 161, the MM file 162, the sales data storage area 120, and the journal file 163 will be described.
FIG. 2 is a schematic diagram illustrating a data structure example of the PLU file 161. The PLU file 161 includes a plurality of records in which product names, unit prices, and the like are associated with PLU codes that are identification information for identifying each product. In the illustrated example, a record in which the product name “product A” and the unit price “¥ 1,000” are assigned to the PLU code “0000000000001”, and the product name “product B” and the unit price “to” are assigned to the PLU code “0000000000002”. A PLU file 161 is composed of records to which “1,500” and the like are assigned.

  FIG. 3 is a schematic diagram illustrating a data structure example of the MM file 162. The MM file 162 includes a plurality of records in which an M & M discount amount and a combination pattern of products are associated with an MM code that is identification information for identifying each M & M discount combination. Each combination pattern is indicated by a PLU code of each product as a component. In the example shown in the figure, an M & M discount amount “¥ 1,500” and a combination pattern “0000000000001,0000000000001,0000000000002” (two products A and one product B) are assigned to the MM code “MM1” The MM file 162 is composed of records in which the M & M discount amount “¥ 500” and the combination pattern “0000000000003,0000000000005” (one product C and one product E) are assigned to the MM code “MM2”. .

FIG. 4 is a schematic diagram showing an example of the data structure of the sales data storage area 120. The sales data storage area 120 is configured by a record in which a product name, a unit price, a sales point, a discount / discount amount, and the like are associated with a PLU code input at the time of accounting. Each record is generated after the PLU code is input. In the illustrated example, the product name “product A”, the unit price “¥ 1,000”, the sales number “2”, etc. are assigned to the PLU code “0000000000001”, and the product name “product name“ 0000000000004 ”is assigned to the product name“ 0000000000004 ”. The sales data storage area 120 is configured by records to which a product D, a unit price “¥ 700”, a sales score “1”, a discount amount “¥ 10”, and the like are assigned. Note that the discount / discount amount here is different from the M & M discount, and represents the discount amount or discount amount for each product.
In the present embodiment, each record stored in the sales data storage area 120 is defined as sales data.

FIG. 5 is a schematic diagram illustrating a data structure example of the journal file 163. As shown in the figure, the journal file 163 is constituted by a journal indicating history information of one transaction. Each journal is configured by associating one or more detailed data with information such as subtotal amount, total amount, current total amount, total score, transaction date and time, etc., for a transaction number for identifying each transaction. . The detailed data is sales data stored in the sales data storage area 120 in each transaction or data relating to M & M discount established in each transaction (hereinafter referred to as MM data). The MM data includes an MM code, the number of components, M & M discount amount, detailed discount amount information, and the like.
The detail discount information is information indicating an amount obtained by apportioning the M & M discount amount to each product according to the unit price of each product that is a component (hereinafter referred to as apportioned discount). For example, in the case of MM data with the MM code “MM1”, the M & M discount amount is “¥ 1,500” and the ratio of product A and product B is (¥ 1,000 × 2): (¥ 1,500). Then, the apportioned discount for product A is “¥ 857”, and the apportioned discount for product B is “¥ 643”. The detailed discount information is configured by associating such apportioned discount amount with the PLU code of the allocation target product.

[Accounting]
Next, accounting processing will be described.
When the PLU key provided on the keyboard 190 is operated, the accounting process is started according to the control program stored in the ROM 11. A flowchart of processing executed by the CPU 10 in the accounting processing is shown in FIG.

  When this process is started, the CPU 10 first receives an input such as a PLU code and various instructions (step S1). The PLU code is obtained by reading a barcode attached to a product with the barcode scanner 150 or by touching a product selection screen displayed on the LCD 171 of the store clerk display unit 170 to designate a specific product. Entered. That is, the barcode scanner 150 and the store clerk display unit 170 in this embodiment function as input means for inputting a PLU code (identification information) of a product.

  Subsequently, the CPU 10 determines whether or not a PLU code has been input (step S2). If the PLU code has been input (Yes in step S2), the CPU 10 generates sales data using the product name, unit price, etc. in the PLU file 161 associated with the input PLU code (step S3). . At this time, if the quantity of the product corresponding to the PLU code is specified, the quantity is set as the sales point in the sales data, and if not specified, the sales point in the sales data is set to “1”. . Further, when a discount amount or discount amount of a product corresponding to the PLU code is input, the amount is set as a discount / discount amount in the sales data. After creating the sales data in this way, the CPU 10 stores the sales data in the sales data storage area 120 and displays the sales data on the LCDs 171 and 181 via the display controllers 17 and 18 (step S4).

  On the other hand, if no PLU code has been input (No in step S2), or after the processing in step S4, the CPU 10 determines whether or not a subtotal instruction has been input (step S5). If the subtotal key provided on the keyboard 190 is not depressed, the CPU 10 determines that the subtotal instruction has not been input (No in step S5), returns to the process in step S1, and inputs the PLU code and the like again. Accept. In this way, input of the PLU code is accepted until the subtotal instruction is input, and sales data corresponding to each input PLU code is accumulated and stored in the sales data storage area 120.

  Eventually, when the subtotal key is operated and a subtotal instruction is input (Yes in step S5), the CPU 10 determines whether or not the M & M discount is established by each sales data stored in the sales data storage area 120 (step S5). S6). Specifically, for each record of the MM file 162, it is determined whether or not the PLU code combination pattern described in each record is established by the PLU code in each sales data stored in the sales data storage area 120. To do. When even one combination pattern is established (Yes in step S6), the CPU 10 executes M & M discount processing (step S7: discount means). The M & M discount process is a process for discounting the discount amount for the established combination pattern described in the MM file 162 from the price of the transaction.

  FIG. 7 shows a flowchart of processing executed by the CPU 10 in the M & M discount processing. When this process is started, the CPU 10 first acquires the MM code and the M & M discount amount from the corresponding record in the MM file 162 for any one of the established combination patterns (step S101). Next, the CPU 10 obtains the number of constituent elements by counting the constituent elements of the combination pattern described in the record (step S102), and obtains a PLU code indicating each constituent element from the record (step S103). .

  Next, CPU10 produces | generates MM data using each information acquired by the process of step S101-S103, and memorize | stores it in RAM12 (step S104). After generating and storing MM data in this way, the CPU 10 determines whether there is a combination pattern that has not been generated yet (step S105). If there is a combination pattern in which MM data has not been generated (Yes in step S105), the processing of steps 101 to S104 is executed for the combination, and MM data is generated and stored. On the other hand, if generation and storage of MM data have been completed for all combinations (No in step S105), the CPU 10 ends the M & M discount process.

  Returning to the flowchart of FIG. After the M & M discount process in step S7, the CPU 10 calculates a prorated discount using the unit price of each product that is a component of the established M & M discount and the discount amount in the M & M discount (step S8: calculation means). . Specifically, the MM code of the MM data generated by the M & M discount process is acquired, and the PLU code of each product that is a constituent element is acquired from the combination pattern in the MM file 162 associated with the acquired MM code. By acquiring the unit price in the PLU file 161 associated with each acquired PLU code, and apportioning the M & M discount amount stored in the MM data according to the ratio of each acquired unit price to each product, Calculate the discount amount. If a plurality of MM data is generated in the M & M discount process, a prorated discount amount is calculated for each MM data.

  After calculating the apportioned discount in this way, the CPU 10 generates detailed discount information by associating each apportioned discount with each PLU code acquired from the MM file 162 in the preprocessing, and adds it to the MM data ( Step S9). If a plurality of MM data is generated in the M & M discount process, detailed discount information is generated and added to each MM data.

  After the process of step S9 or when it is determined in the process of step S6 that the M & M discount is not established (No in step S6), the CPU 10 stores each sales data stored in the sales data storage area 120 and the RAM 12. Based on each MM data, a subtotal amount, a tax amount, a total amount, etc. of the transaction are calculated (step S10), and the calculation result is stored in the RAM 12, and the LCDs 171 and 181 are displayed via the display controllers 17 and 18. (Step S11).

After displaying the subtotal amount and the like, the CPU 10 waits for the input of the tightening instruction (No in Step S13) while receiving the input of the deposit amount from the customer (Step S12). If the deposit / current total key is pressed while the deposit amount has been input via the keyboard 190, the CPU 10 determines that a tightening instruction has been input (Yes in step S13), and the entered deposit amount and step The total amount and change amount are calculated using the total amount stored in the RAM 12 in the process of S11 (step S14). Then, the CPU 10 stores the calculated total amount and change amount in the RAM 12 and displays them on the LCDs 171 and 181 via the display controllers 17 and 18 (step S15). In the case where payment is made by a method other than cash payment, such as credit card payment or electronic money payment, the processing in steps S12 to S15 may be changed to processing suitable for each payment method.
Here, the processing of steps S10 to S15 is a settlement processing means for performing settlement processing of the transaction using the sales data stored in the sales data storage area 120 and the M & M discount amount in the MM data generated by the M & M discount processing. Configure.

  When the payment is completed in this way, the CPU 10 assigns a transaction number to the transaction, and stores the transaction number, current date and time information counted by the clock circuit 13, and stored in the sales data storage area 120 in the process of step S4. Sales data, the MM data stored in the RAM 12 in the process of steps S7 and 8, the subtotal stored in the RAM 12 in the process of step S11, and the current total stored in the RAM 12 in the process of step S15. Etc. are used to generate a journal for the transaction (step S16). The generated journal is added to the journal file 163 (step S17).

  After adding the journal to the journal file 163, the CPU 10 drives the receipt printer 210 via the printer controller 21 to issue a receipt corresponding to the journal (step S18). Thus, the accounting process for one transaction is completed.

[Journal browsing process]
Next, a method for browsing each journal constituting the journal file 163 will be described.

  When the journal key 191 provided on the keyboard 190 is pressed, an instruction for browsing each journal constituting the journal file 163 is input. When the instruction is input in this way, the journal browsing process is started according to the control program stored in the ROM 11. A flowchart of processing executed by the CPU 10 in the journal browsing processing is shown in FIG.

  When this process is started, the CPU 10 first displays a predetermined input screen on the LCD 171 via the display controller 17 and accepts the input of journal identification information (step S201), and waits for the completion of the input (in step S202). No). The journal identification information is information for specifying a journal to be browsed, and is, for example, a transaction number or date / time information. When journal identification information is input by operating the keyboard 190 (Yes in step S202), the CPU 10 searches the journal file 163 for a journal identified by the journal identification information (step S203). When the corresponding journal is found, the CPU 10 displays information indicated by the journal on the LCD 171 via the display controller 17 (step S204), and the journal browsing process is completed.

  An example of information displayed on the LCD 171 in the process of step S204 is shown in FIG. This example is based on a journal generated when a transaction is closed in a state where records as shown in FIG. 4 are stored in the sales data storage area 120. The date and time information “October 1, 2009 (Thursday) 12:43 "and subtotal amount, total amount, transaction number, etc." Subtotal ¥ 3,490 ... ", areas AR1, AR2, AR3,. .

  The areas AR1 and AR2 correspond to the sales data of the product A, and the PLU code “0000000000001”, the product name “product A”, the unit price “¥ 1,000”, and the like are displayed. The area AR3 corresponds to the sales data of the product B, and the PLU code “0000000000002”, the product name “product B”, the unit price “¥ 1,500”, and the like are displayed. The area AR5 corresponds to the sales data of the product C, and the PLU code “0000000000003”, the product name “product C”, the unit price “¥ 800”, and the like are displayed. The area AR6 corresponds to the sales data of the product D, and the PLU code “0000000000004”, the product name “product D”, the unit price “¥ 700”, the discount / discount amount “−10”, and the like are displayed. Yes.

  The combination pattern of the MM code “MM1” shown in FIG. 3 is established with two products A and one product B. MM data corresponding to this M & M discount is represented in area AR4. The area AR4 includes an MM code “MM1”, the number of components “3”, an M & M discount amount “−1,500”, and detailed discount information. The detail discount information is titled “detail discount”, and “−857” yen of the M & M discount amount is apportioned to the product “2” with the PLU code “0000000000001”, and the product “with the PLU code“ 0000000000002 ”“ It means that “-643” yen of M & M discount amount will be prorated for “1”.

  As described above, the journal displayed on the LCD 171 displays the PLU code for specifying the product, which is a component of the combination pattern of M & M discount, and the prorated discount for the product. By checking this journal, the cashier can grasp the prorated amount of each product without calculating it by himself.

[Search Returns]
Next, a search return process for returning a product sold in a past transaction will be described.
When the search return key 192 provided on the keyboard 190 is depressed, an instruction for starting the return processing of the settled product is input. When the instruction is input in this way, the search return process is started in accordance with the control program stored in the ROM 11. FIG. 10 shows a flowchart of processing executed by the CPU 10 in the search return processing.

  When this process is started, the CPU 10 first displays a predetermined input screen on the LCD 171 via the display controller 17 and accepts the input of journal identification information (step S301), and waits for the completion of the input (in step S302). No). When journal identification information is input by operating the keyboard 190 (Yes in step S302), the CPU 10 searches the journal file 163 for a journal identified by the journal identification information (step S303). When the journal is found, the CPU 10 displays a search return screen on the LCD 171 via the display controller 17 (step S304).

  An example of the search return screen is shown in FIG. The search return screen 400 shown in the figure has screen components such as a detailed data display area 401, a batch selection button 402, a selection cancel button 403, a return button 404, a cancel button 405, a confirmation button 406, and a return button 407. The collective selection button 402, the selection cancel button 403, the return button 404, the cancel button 405, the confirmation button 406, and the return button 407 are screen components that can be touched via the touch panel 172.

  The detail data display area 401 includes a department area 411 in which a department code for identifying a department of a product is represented, a product name area 412 in which a product name is represented, a unit price area 413 in which a unit price is represented, and a score in which sales points are represented. Area 414, discount discount area 415 that represents the discount / discount amount for a single item, amount area 416 that represents the amount obtained by multiplying the unit price by the number of sales points, and the discount / discount amount, and an apportioned discount amount. The detailed discount area 417 and the like. A department area 411, a product name area 412, a unit price area 413, a point area 414, a discount discount area 415, and an amount area 416 included in one line of the detailed data display area 401 include detailed data that is sales data in the journal. Information is displayed based on the details, and information is displayed in the detail discount area 417 based on the detail data which is MM data in the journal. In other words, the amount shown in the detail discount area 417 is a prorated discount for the product shown in the product name area 412 on the same line.

  The illustrated example shows a search return screen 400 displayed based on a journal generated when a transaction is closed in a state where a record as shown in FIG. 4 is stored. In a first line area 411 to 416, a department “0001”, a product name “product A”, a unit price “1,000”, a sales point “2”, and an amount “2,000” are displayed. 416 shows a section “0001”, a product name “product B”, a unit price “1,500”, a sales point “1”, and an amount “1,500”. The areas 411 to 416 in the third line indicate a section “0001”, a product The name “product C”, the unit price “800”, the number of sales points “1”, and the amount “800” are represented. The areas 411 to 416 in the fourth line have a department “0001”, a product name “product D”, and a unit price “700”. ”, Sales point“ 1 ”, discount / discount amount“ −10 ”, amount“ 690 ” It is.

  In this example, as described above, the M & M discount of the MM code “MM1” shown in FIG. 3 is established. Accordingly, the detailed data of the journal includes MM data corresponding to the MM code “MM1”. Since it is based on such a journal, an apportioned discount amount “−857” of two products A is displayed in the detail discount area 417 of the first line of the detail data display area 401, and the detail discount area of the second line. Reference numeral 417 represents the apportioned discount “−643” of the product B. Note that a letter “M” indicating a component is attached to the end of the line corresponding to the product that is a component of the combination pattern of M & M discount.

  In a state where such a search return screen 400 is displayed, the CPU 10 receives an operation on the search return screen 400 and executes a process corresponding to the operated button (step S305).
