  Hereinafter, an embodiment applied to a POS terminal (Point Of Sales) as a merchandise sales data processing apparatus will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a main configuration of the POS terminal 11.

  As shown in FIG. 1, the POS terminal 11 includes a CPU (Central Processing Unit) 21 as a main control unit, a ROM (Read Only Memory) 22 and a RAM (Random Access Memory) 23 as main storage units controlled by the CPU 21. Is installed. The CPU 21 includes a ROM 22, RAM 23, auxiliary storage unit 24, clock unit 25, communication interface (I / F) 26, I / O port (Input / Output) 27, keyboard controller 28, scanner controller 29, first and first. 2 Each unit such as the display unit controllers 30 and 31, the printer controller 32, and the card reader controller 33 is connected via a bus line 35 such as an address bus, a data bus, and a control bus.

  A mode switch 36 and a drawer opening 37 are connected to the I / O port 27, a keyboard 38 is connected to the keyboard controller 28, a scanner 39 is connected to the scanner controller 29, and the first display unit controller 30 is connected to the front surface. A display 40 is connected, a customer display unit 41 is connected to the second display unit controller 31, a printer 42 is connected to the printer controller 32, and a card reader 43 is connected to the card reader controller 33.

  The CPU 21 controls each unit that implements various operations as the POS terminal 11 based on an operating system, middleware, and application programs stored in the ROM 22 and the RAM 23.

  The ROM 22 stores fixed data such as a basic control program of the POS terminal 11.

  Further, a font memory is stored in the ROM 22 as a character generation device. A part of the font memory stores a normal character font memory and an enlarged character font memory having a larger character than that of the normal character font. The normal character font memory stores a normal character font, and the enlarged character font memory stores an enlarged character font. The OS acquires the character shape from the font memory.

  The RAM 23 stores data referred to when the CPU 21 performs various processes. Further, the RAM 23 stores data temporarily used for performing various processes. It is used as a so-called work memory. A part of the storage area of the RAM 23 is used as a transaction information area.

  FIG. 2 is a schematic diagram illustrating a data structure example of a transaction information area formed in the storage area of the RAM 23.

  As shown in FIG. 2, a transaction information memory 51, a customer layer information memory 52, and a print memory 53 are formed.

  The transaction information memory 51 includes a transaction number area, a transaction date / time area, a cash register No area, a responsible person code area, a responsible person name area, a PLU code area, a product name area, a unit price area, a sales point area, a sales amount area, and a subtotal amount. A transaction information record including an area, a tax-exempt amount area, a consumption tax area, a total amount area, a deposit amount area, a change amount area, a total point area, and the like is temporarily stored. Here, the transaction information memory 51 functions as a transaction information storage unit.

  The customer segment information memory 52 stores customer segment information representing the customer segment.

  The customer group is a hierarchy that divides customers according to their characteristics. A customer segment record including customer segment code, customer segment age and gender is stored as customer segment information. The customer base is mainly determined by age and gender. In other words, the customer base is defined as, for example, “20's, male”, “20's, female”, “elderly, male” and “elderly, female”.

  The customer base is determined so that the store clerk can judge from the appearance of the customer. Here, the customer segment information memory 52 functions as a customer segment information storage unit.

  The print memory 53 is configured to temporarily store the receipt print data stored in the transaction information memory 51 for one commercial transaction.

  The auxiliary storage unit 24 is, for example, a hard disk drive or an SSD (Solid State Drive), and stores data used when the CPU 21 performs various processes and data generated by the processes in the CPU 21.

  The data stored in the auxiliary storage unit 24 includes a customer-specific character information table 61, a PLU (Price Look Up) file, and other files.

  FIG. 3 is a schematic diagram showing a data structure of character information for each customer segment code that is set and stored in the customer segment-specific character information table 61.

  As shown in FIG. 3, a flag F is set as character information corresponding to the customer segment code. The customer segment code is set to “1” to “0”, and the character information flag F is set to either “0” or “1” corresponding to the customer segment code.

  When the character information flag F is set to “0” (customer layer code: 1 to 8), the CPU 21 is a normal character font, and printing on the receipt 110 (see FIG. 7) is a normal character. This is done with fonts.

  When the character information flag F is set to “1” (customer layer code: 9 to 0), the CPU 21 uses the receipt 120 (FIG. 8) because the expanded character font is used and the customer group is “elderly”. Is printed with an enlarged character font.

  The PLU file stores a product name, a unit price, etc. corresponding to a PLU code as information about a product sold or provided at a store where the POS terminal 11 is used.

  When the POS terminal 11 is activated, all or a part of the data stored in the auxiliary storage unit 24 is copied to the RAM 23. In accordance with each data copied to the RAM 23, the CPU 21 executes each process.

  The clock unit 25 constantly performs a timekeeping operation and generates date and time information representing the date and time.

  The communication interface (I / F) 26 controls data communication via the server 12 and the communication network 13.

  The server 12 is a headquarter server installed in a headquarters that manages a store server provided in the same store where the POS terminal 11 is installed and a plurality of stores including the same store where the POS terminal 11 is installed. It is.

  The server 12 aggregates product sales data generated by the POS terminal 11 and other POS terminals, and manages data used by each POS terminal. The server 12 stores a PLU file for distribution to the POS terminal 11 and other POS terminals and a character information table 61 for each customer group.

  A mode signal is input from the mode switch 36 to the I / O port 27. Further, an opening command signal for automatically opening the drawer under the control of the CPU 21 is output to the drawer opening unit 37.

  The mode switch 36 is a change-over switch for selecting any one of various business modes such as “registration”, “inspection”, “settlement”, and “setting” and notifying the CPU 21 of the execution.

  Incidentally, in the “registration” mode, the transaction information of the merchandise sales data registered by the merchandise registration means is registered in the transaction information memory 51 formed in the RAM 23, and the receipt print data including the registered transaction information is generated. This is a mode for executing the product registration work to be performed.

  In addition, when the subtotal key is entered after executing the product registration operation as a single transaction, the consumption tax is calculated by multiplying the subtotal amount of the tax-excluded product of the registered product by a preset tax rate. The total amount is calculated by adding the subtotal amount of the registered products, and the total amount is displayed on the front display 40 and the customer display unit 41. The subtotal amount, the amount subject to external tax, the tax rate, the consumption tax, the total amount, etc. It is also a mode for executing a subtotal operation for generating receipt print data consisting of

  Further, when the deposit / actual total key functioning as a registration closing means is input after the subtotal operation is executed, the change amount is calculated by subtracting the total amount from the deposit amount, and this change amount is displayed on the front display 40 and the customer. The receipt display data including the total amount, the deposit amount, the change amount, the transaction number, the transaction date and time, the responsible person code and the responsible person name is generated and displayed on the surface display unit 41. This is a mode for executing a registration closing work that is printed out at 120.

  “Inspection” is a business mode in which transaction information registered in the transaction information memory 51 is displayed or printed out as an inspection report.

  The “settlement” mode is a business mode for clearing the transaction information in the transaction information memory 51 after issuing a settlement report on which the contents of the transaction information memory 51 are printed, as in the “check” mode.

  The “setting” mode is a job mode in which data necessary for executing various jobs is set in the RAM 23.

  The keyboard controller 28 receives a key signal corresponding to the operation key from the keyboard 38, obtains key input data, and outputs it to the CPU 21.

  As shown in FIG. 4, the keyboard 38 is used to input a numeric key such as the amount of registration products “00” and “0” to “9”, numeric data such as PLU code, and a PLU code. PLU (Price Look Up) key, department key to indicate that the numerical data is a department code, x key, cancel key, clear key, subtotal key to instruct subtotal output of one transaction, registration by cash transaction of one transaction In addition to the deposit / current total key that is designated as the closing means, the credit key that is designated as the registration closing means by the margin transaction of the commercial transaction, the discount key, etc., 10 customer code “1” to “0” are preset respectively. Customer layer key K1 is arranged.

  The customer segment key K1 functions as a customer segment input means for inputting the customer segment of each customer for each commercial transaction.

  Note that the PLU code can also be input by the PLU key and the numeric key of the keyboard 38, and the PLU key and the numeric key constitute a product registration unit.

  The scanner controller 29 controls the operation of the scanner 39 under the control of the CPU 21 and writes the scan data generated by the scanner 39 into the RAM 23.

  The scanner 39 scans and inputs a bar code written on a product.

  Here, the scanner controller 29 and the scanner 39 constitute a product registration unit.

  The first display controller 30 controls the screen display of the front display 40 according to a command from the CPU 21.

  The front display 40 is an LCD (Liquid Crystal Display), for example, and can display an arbitrary image under the control of the CPU 21. Further, it is used for displaying an image representing various information to the operator.

  The second display unit controller 31 controls the screen display of the customer surface display unit 41 in response to a command from the CPU 21.

  The customer surface display unit 41 is an LCD, for example, and can display an arbitrary image under the control of the CPU 21. The customer surface display unit 41 is used to display an image representing various types of information to the customer.

  The printer controller 32 controls the operation of the printer 42 under the control of the CPU 21.

  The printer 42 is a thermal printer, for example, and prints out the receipts (110, 120) based on the receipt data in the print memory 53.

  The card reader controller 33 controls the operation of the card reader 43 under the control of the CPU 21 and writes the card information output from the card reader 43 into the RAM 23.

  The card reader 43 reads card information recorded on the payment card. The payment card is a card for making payment without using cash, and includes a credit card and a prepaid card.

  Next, the operation of the POS terminal 11 configured as described above will be described.

  FIG. 5 and FIG. 6 are flowcharts showing steps of merchandise sales data processing executed by the CPU 21 based on the control program stored in the ROM 22. That is, in a state where the “registration” mode is selected by the mode switch 36, the CPU 21 waits for product registration (step ST11). Alternatively, it waits for any customer key K1 to be input (step ST12).

  In this standby state, the CPU 21 determines whether or not a product has been registered in step ST11. In step ST12, the CPU 21 determines whether any customer segment key K1 has been input.

  When the scanner 21 inputs a PLU code represented as a barcode on a product or inputs a PLU code by a key operation on the keyboard 38 (YES in step ST11), the CPU 21 inputs the PLU code. Is temporarily stored in the RAM 23 by the scanner controller 29 or the keyboard controller 28. In this way, the PLU code as the product information is acquired. In response to this, the CPU 21 determines that there is a commodity registration. When product registration is performed, the process proceeds from step ST11 to step ST13.

  In step ST13, the CPU 21 executes a merchandise sales data registration process. That is, the CPU 21 acquires the product name and unit price corresponding to the PLU code of the registered product at step ST11 from the PLU file formed in the auxiliary storage unit 24. The CPU 21 multiplies the unit price by the number of sales points to calculate a sales amount, and registers the product sales data including the PLU code, the product name, the unit price, the sales point, and the sales amount in the transaction information memory 51 of the RAM 23.

  Further, the CPU 21 causes the front display 40 and the customer display unit 41 to display the product name, the sales score, and the sales price of the product sales data registered in the transaction information memory 51 as step ST14.

  Thereafter, the CPU 21 returns to the standby state of step ST11 or step ST12.

  On the other hand, if any one of the customer segment keys K1 is input, the key code related to the input customer segment key K1 is temporarily stored in the RAM 23 via the keyboard controller 28. In response, CPU 21 determines YES in step ST12 and proceeds from step ST12 to step ST15.

  In step ST15, since any one of the customer segment keys K1 is input, the CPU 21 acquires a customer segment code preset for the input customer segment key K1. Then, the customer segment code of the customer segment information is overwritten and stored in the customer segment information memory 52.

  Next, the CPU 21 determines whether or not the subtotal key of the keyboard 38 is input (step ST16).

  When it is determined that the subtotal key has not been input (NO in step ST16), the process returns to step ST11 again to wait for the next product registration.

  On the other hand, when it is determined that the subtotal key has been input (YES in step ST16), as step ST17, the CPU 21 calculates a subtotal amount of one commercial transaction and calculates a total amount obtained by adding the consumption tax to the subtotal amount. , Display on the front display 40 and the customer display 41.

  Further, the CPU 21 stores the transaction information such as the subtotal amount and the total amount in the transaction information memory 51 and the print memory 53 as step ST18.

  In step ST19, the CPU 21 waits for any one of the customer segment keys K1 to be input again. Then, in response to the input of any one of the customer segment keys K1, the CPU 21 determines YES in step ST19, and proceeds from step ST19 to step ST20.

  In step ST20, if any one of the customer segment keys K1 is input, the CPU 21 overwrites and stores the customer segment code in the customer segment information memory 52 as the customer segment information preset in the customer segment key K1.

  If the CPU 21 determines in step ST19 that the customer segment key K1 is not input (NO in step ST19), the process proceeds to step ST21.

  Next, the CPU 21 waits for a deposit / cash key to be input in step ST21. If the deposit / cash key is not input (NO in step ST21), the process returns to step ST19 and waits for any one of the customer segment keys K1 to be input.

  On the other hand, when the deposit / cash total key is input (YES in step ST21), in step ST22, the CPU 21 executes a registration closing process. That is, when a deposit amount from a customer is input by inputting a numeric key and a deposit / cash key on the keyboard 38, a change amount is obtained by subtracting the total amount from the deposit amount of one commerce transaction. The information is displayed on the display 40 and the customer surface display unit 41.

  In step ST <b> 23, the CPU 21 causes the transaction information memory 51 and the print memory 53 to additionally store transaction information of the registration closing process such as the total amount, the deposit amount, and the change amount that have been subjected to the registration closing process.

  Next, in step ST24, the CPU 21 reads the latest customer segment code stored in the customer segment information memory 52.

  In step ST25, the CPU 21 checks a character information flag F (0: normal character font, 1: enlarged character font) for the customer layer code in the customer layer-specific character information table 61. When the CPU 21 determines that the character information flag F corresponding to the customer segment code is “1” and is an enlarged character font, the CPU 21 stores it in the enlarged character font memory of the ROM 22 in step ST26. Enlarged character receipt data for selecting the enlarged character font and printing it on the receipt 120 is generated. Further, the enlarged character receipt data is stored in the print memory 53.

  In step ST27, the CPU 21 controls the printer 42 and prints out the receipt 120 using the enlarged character receipt data stored in the print memory 53 (enlarged character print output means).

  On the other hand, when the CPU 21 determines in step ST25 that the character information flag F corresponding to the customer segment code is "0" and is a normal character font, the CPU 21 determines in step ST28 that the normal character font memory in the ROM 22 is used. The normal character receipt data for selecting the normal character font stored in and printing on the receipt 110 is generated. Further, the normal character receipt data is stored in the print memory 53.

  In step ST28, the CPU 21 controls the printer 42 and prints it on the receipt 110 based on the normal character receipt data stored in the print memory 53 (normal character print output means).

  The merchandise sales data processing in the “registration” mode of the POS terminal 11 is thus completed.

  As described above, according to the POS terminal 11 of the present embodiment, the customer's customer base is determined within one transaction period from the start of the product registration process for one commercial transaction to before the registration closing process, and the operator's operation is performed. It is possible to determine the customer base according to the response. Accordingly, since the customer key can be re-input until immediately before the registration closing process, if there is a doubt about the customer layer, it is possible to easily re-input with the customer key.

  In the above embodiment, the normal character font and the enlarged character font are used separately to enable enlargement printing for the elderly. However, as another method, it is classified into the first term elderly and the latter term elderly. For the elderly, the enlarged characters may be made larger than the elderly in the previous term and printed on the receipt.

  In this way, for customers such as elderly people who are difficult to see fine characters, it is possible to print out a receipt with an enlarged character font larger than a normal character font. Therefore, the visibility of the receipt 120 of an elderly person or the like can be improved.

  In the above embodiment, when receipt data is printed, all the receipt data is printed in normal characters. However, some of them, for example, important amount data may be printed in an enlarged character font. .

  In addition, this invention is not limited to the said embodiment as it is, In an implementation stage, within the range which does not deviate from the summary, each component can be changed suitably and can be embodied.

  For example, in the embodiment, the PLU file may be stored in the server 12 instead of being stored in the auxiliary storage unit 24 of the POS terminal 11.

Although the embodiments of the present invention have been described, these embodiments are presented as examples, and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various changes, substitutions, and deletions of components can be made without departing from the spirit of the invention.
