Description

  Embodiments described herein relate generally to a product sales data processing apparatus such as a POS (Point Of Sales) terminal or an electronic cash register, and a product sales program for causing a computer to function as the product sales data processing apparatus.

  One of the methods for selling products at a bargain price lower than the normal price is a limited quantity bargain. In this special sale, for example, up to 3 items with a normal price of 150 yen are sold for 100 yen. In one commercial transaction, a target product is sold at a preset price up to a preset limited number. It is.

  As a product sales data processing apparatus corresponding to such special sale, it is determined whether or not a product registered for sale as one commercial transaction is a product subject to limited quantity sale, a so-called sale restricted product. It is known to count the number of points sold and to issue a warning if the number of points sold exceeds the limited number of special sales.

  By the way, for the amount exceeding the limit number, it is considered that the operation is prohibited to sell and the operation to sell at a normal price. When selling at the normal price, the cashier is required to explain to the customer that the limited number of special sales has been exceeded and that it will be sold at the normal price. To that end, the cashier himself / herself needs to know the sale price and the regular price of the sale restricted product, which is a burden.

Hereinafter, an embodiment of a merchandise sales data processing apparatus corresponding to a limited quantity sale will be described with reference to the drawings.
In this embodiment, the present invention is applied to a POS terminal 10 installed at a so-called manned cash register where a supermarket cashier is located.

  FIG. 1 is a block diagram showing a main configuration of the POS terminal 10. The POS terminal 10 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a clock unit 104, a communication interface 105, a drawer interface 106, a keyboard controller 107, a touch panel controller 108, a display A controller 109, a printer interface 110, and a scanner interface 111 are installed. The POS terminal 10 configures a control circuit by connecting these mounted components 101 to 111 to a bus line 112 such as an address bus and a data bus.

  The CPU 101 corresponds to the central part of the computer. The CPU 101 controls each unit to implement various functions as the POS terminal 10 in accordance with the operating system and application programs.

  The ROM 102 corresponds to the main storage portion of the computer. The ROM 102 stores the above operating system and application programs. The ROM 102 may store data necessary for the CPU 101 to execute processing for controlling each unit.

  The RAM 103 corresponds to the main storage portion of the computer. The RAM 103 stores data necessary for the CPU 101 to execute processing. The RAM 103 is also used as a work area where information is appropriately rewritten by the CPU 101.

The clock unit 104 measures the current date and time.
The communication interface 105 manages data communication with an external device connected via a network such as a LAN (Local Area Network). Examples of the external device include other POS terminals and a POS server (not shown) that is a host server.

  The drawer interface 106 outputs an opening signal to the drawer 20 for storing cash or the like. When the opening signal is output, the drawer 20 opens and money can be delivered by the cashier. The POS terminal 10 may be connected to an automatic change machine instead of the drawer 20. In that case, the drawer interface 106 outputs change data to the automatic change machine. When change data is output, the automatic change machine pays out change according to the data.

  The keyboard controller 107 controls the keyboard 21. The keyboard 21 has a numeric key for entering numerical values such as sales points and deposit amounts, a multiplication key for indicating that the numeric value is a multiplier, a subtotal key for indicating a subtotal, and a registration closing for one commercial transaction. This is a dedicated keyboard with various function keys such as the key to be declared. A function necessary for the POS terminal 10 may be assigned to an arbitrary key of a general-purpose keyboard. The keyboard controller 107 takes in a key signal corresponding to the operation key from the keyboard 21 and gives it to the CPU 101.

  The touch panel controller 108 controls the touch panel 22 which is a cashier display. The touch panel 22 includes a panel type display and a touch panel sensor superimposed on the screen of the display. The touch panel controller 108 controls display on the panel type display. The touch panel controller 108 detects a touch position on the screen detected by the touch panel sensor, and gives coordinate data indicating the position to the CPU 101. The touch panel 22 is a device for displaying a product name, a price, a total amount, a change amount and the like to a cashier who is an operator of the POS terminal 10.

  The display controller 109 controls display on the customer display 23. The customer display 23 is a device for displaying a product name, a price, a total amount, a change amount, and the like to a customer who performs accounting.

  The printer interface 110 exchanges data signals with the printer 24. The printer 24 has a receipt printing function and a journal printing function. That is, the printer 24 prints the receipt data on the receipt paper in accordance with the data signal from the printer interface 110 and prints the journal data on the journal paper. The receipt paper on which the receipt data is printed is cut by a cutter and issued as a receipt. The journal paper on which the journal data is printed is taken up inside the POS terminal 10. Note that the printer 24 not having the journal printing function may be applied because the POS terminal 10 has the electronic journal function.

  The scanner interface 111 exchanges data signals with the scanner 25. The scanner 25 optically reads a code symbol (bar code, two-dimensional data code, etc.) attached to a product and outputs the code data to the scanner interface 111. The scanner interface 111 decodes the code data fetched from the scanner 25 and provides the decoded data, for example, a product code, to the CPU 101.

  The CPU 101 has a function of searching for a product file using the product code as a search key when the data provided via the scanner interface 111 is a product code. The product file is mounted on a POS server connected via the communication interface 105. Or the product file which a POS server has is made into a master file, and the local file of a product file may be downloaded to the memory | storage part (for example, RAM103) of each POS terminal 10. FIG.

  In the product file, a product data record 30 created for each product is stored. The main part of the data structure of the product data record 30 is shown in FIG. As shown in FIG. 2, the product data record 30 includes data items of a product code, a product name, a normal unit price, a number limit flag, a limit number RN, and a sale unit price.

  The product code is a unique code set for each product type. Each product is identified by its product code. The product name is the name of the product of the type specified by the corresponding product code (hereinafter referred to as the product), and the normal unit price is the selling price per point of the product. The number restriction flag is a flag for identifying whether or not the product is a sale limited product that is a target of the number limited sale. In the present embodiment, the number limit flag for the sale limited product is set to “1”, and the number limit flag for the non-sale limited product is set to “0”. When the product is a sale limited product, the limited number RN and the sale unit price are set in the product data record 30. The special sale unit price is a selling price per point of the product, and an amount lower than the normal price is set.

  If a product data record 30 including a product code as a search key is detected as a result of searching the product file, the CPU 101 generates product sales data based on the product data of the product data record 30 and performs registration processing. . Further, the CPU 101 causes the touch panel 22 and the customer display 23 to display the product name, the number of sales points, the sales price, etc. of the product sales data.

  FIG. 3 is an example of a registration screen 40 displayed on the touch panel 22. The registration screen 40 is divided into a current area 41, a detail area 42, and a total area 43. In the current area 41, the product name, the number of sales points, and the sales amount of the latest registered product sales data are displayed. In the detail area 42, a list of product names, sales points, unit prices (normal unit price or special unit price), sales amounts, etc. of each product sales data registered as one commercial transaction is displayed. In the detail area 42, an attribute column is provided. In this column, a predetermined identification mark 421 is displayed when the product of the corresponding sales data is a special sale restricted product. The total area 43 displays the total score and total amount of each item sales data registered as one commercial transaction.

  In order to display the registration screen 40 described above on the touch panel 22, the POS terminal 10 forms the memory areas LM, CM, TM, RM, FM, MM, NM, SM shown in FIG.

The memory area LM is an area for storing the product code, the product name, the unit price, the number of sales, the sales amount, and the number limit flag of each product sales data registered as one commercial transaction in the order of a series of numbers. Called.
The memory area CM is an area for storing the product code, the product name, the unit price, the number of sales, the sales price, and the number limit flag of the latest product sales data registered for sale, and is hereinafter referred to as a current memory CM.

The memory area TM is an area for storing the total score TN and the total amount TA of each product sales data registered as one commercial transaction, and is hereinafter referred to as a total memory TM.
The memory area RM is an area for storing a product code, a product name, a normal unit price, a special unit price, a limited number, and a sales point of a limited sale limited product, and is hereinafter referred to as a limited memory RM.

The memory area FM is an area for storing the registration flag f, and is hereinafter referred to as a flag memory FM.
The memory area MM is an area for storing a multiplier m input by operating the numeric key and the multiplication key, and is hereinafter referred to as a multiplier memory MM.
The memory area NM is an area for storing the registered number counter p, and is hereinafter referred to as a count memory NM.
The memory area SM is an area for storing status data ST, and is hereinafter referred to as a status memory.

Accordingly, the POS terminal 10 is mounted with a program for causing the CPU 101 to realize the following functions 1 to 6, that is, a so-called product sales program.
Function 1. A function that identifies the products that customers purchase.

Function 2. Ability to process sales data for identified products.

Function 3. A function for determining whether or not the specified product is a limited sale product with a limited sales volume at a sale price lower than the normal price.

Function 4. A function for confirming whether or not the sales amount of a limited sale product exceeds the limit when the limited sale product is included in the product purchased by the customer as one commercial transaction.

Function 5. A function of notifying the operator of the normal price and the special sale price of the product when the sales volume of the special sale restricted product exceeds the limit.

Function 6. A function of accepting a selection as to whether or not to proceed with processing of a product when the sales amount of the limited sale product exceeds the limit.

  The product sales program is stored in the ROM 102. If the POS terminal 10 is equipped with, for example, an EEPROM (Electric Erasable Programmable Read-Only Memory), a hard disk drive, or an SSD (Solid State Drive) as an auxiliary storage device of the computer, the product sales program is stored in the auxiliary storage device. May be.

  5 to 7 are flowcharts showing the main part of the information processing procedure executed by the CPU 101 in accordance with the product sales program. Note that the contents of the processes illustrated in FIGS. 5 to 7 and described below are merely examples, and various processes capable of obtaining similar results can be used as appropriate.

  When the barcode (including the product code) attached to the product is read by the scanner 25 and the barcode data is input via the scanner interface 111, the CPU 101 starts the processing shown in the flowchart of FIG.

  First, the CPU 101 checks the registering flag f in the flag memory FM (Act1). The registering flag f is reset to “0” at the time of the first product registration in one commercial transaction, and is set to “1” at the second and subsequent product registration.

  When the registering flag f is reset (YES in Act1), the CPU 101 proceeds to the process of Act4 after executing the processes of Act2 and Act3. When the registering flag f is set (NO in Act 1), the CPU 101 proceeds to the process of Act 4 without executing the processes of Act 2 and Act 3. Note that the processing order of Act2 and Act3 may be reversed.

  In Act 2, the CPU 101 initializes the memory and the screen. By this initialization, each data of the list memory LM, the current memory CM, the total memory TM, and the limited memory RM is cleared. Further, the registered number counter p of the count memory NM is reset to “0”. Furthermore, the registration screen 40 of the touch panel 22 is in an initial state. That is, the display contents of the current area 41 and the detail area 42 are deleted. In the total area 43, the total score “0 points” and the total amount “0 yen” are displayed.

  In Act 3, the CPU 101 sets the registration flag f to “1”. With this processing, the registration flag f is set to “1” at the time of the second and subsequent product registration.

  In Act 4, the CPU 101 searches for a product file with the input product code, and acquires a product data record 30 including this product code. When the product data record 30 can be acquired, the CPU 101 considers that the customer can specify the product to be purchased. Here, the processing of Act4 realizes a function of specifying a product purchased by the customer (specifying means). If the product data record 30 cannot be acquired, the product purchased by the customer cannot be specified. In this case, although not shown, the CPU 101 makes an error in inputting the product code.

  If the product data record 30 is acquired, the CPU 101 determines whether or not the product of the record 30 is a sale limited product (Act 5). When the number limit flag of the record 30 is set to “1”, the CPU 101 recognizes that the item is a limited sale commodity. When the number limit flag of the record 30 is reset to “0”, the CPU 101 recognizes that the record 30 is not a limited sale commodity. Here, the processing of Act 5 realizes a function of determining whether or not the product specified by the specifying means is a sale limited product with a limited sales volume at a sale price lower than the normal price (determination means). ).

  If it is not a special sale restricted product (NO in Act 5), the CPU 101 proceeds to the Act 7 process after executing the Act 6 process. If it is a sale limited product (YES in Act 5), the CPU 101 proceeds to a number limiting process described later (Act 13).

  In Act 6, the CPU 101 sets the status data ST in the status memory SM to “0”.

  In Act 7, the CPU 101 checks the registered number counter p in the count memory NM. The registration number counter p is reset to “0” at the time of the first product registration in one commercial transaction. When the registered number counter p is “0” (YES in Act 7), the CPU 101 proceeds to the process of Act 9 without executing the process of Act 8.

  In Act 9, the CPU 101 increments the registration number counter p by “1”. Therefore, when registering the second and subsequent items in one commercial transaction, the registration number counter p takes a value of “1” or more. When the registered number counter p is “1” or more (NO in Act 7), the CPU 101 executes the process of Act 8 and then proceeds to the process of Act 9.

  In Act 8, the CPU 101 uses the data stored in the current memory CM (product code, product name, unit price, number of sales points, sales price and number limit flag) as the number p of the list memory LM (p is the value of the registration number counter p). ).

  After counting up the registration number counter p in Act 9, the CPU 101 executes a sales data generation process described later (Act 10). Since the sales data generation process determines the sales score SN and the sales amount SA of the product for which the product code is input, the CPU 101 adds the sales point SN to the total score TN of the total memory TM and totals the sales amount SA. Add to the total amount TA of the memory TM (Act11).

  Thereafter, the CPU 101 performs display processing (Act 12). That is, the CPU 101 displays the data in the current memory CM in the current area 41 of the registration screen 40 on the touch panel 22, displays the data in the detail memory LM in the detail area 42, and displays the data in the total memory TM in the total area 43. Further, the CPU 101 displays the data of the current memory CM on the customer display 23. As described above, the CPU 101 ends the process for inputting the product code.

  FIG. 6 is a flowchart specifically showing the procedure of the number limiting process. In Act 13, when the number limit process is started, the CPU 101 searches the limit memory RM with the input product code (Act 31). Then, the CPU 101 confirms whether or not the same product code is stored in the restriction memory RM (Act 32).

  If not stored (NO in Act 32), the CPU 101 executes the process of Act33 after executing the process of Act33. If it is stored (YES at Act 32), the CPU 101 executes the process of Act 34 without executing the process of Act 33.

  In Act 33, the CPU 101 stores the product code, the normal unit price, the special unit price, and the limited number RN of the product data record 30 acquired in the process of Act4 in the limited memory RM.

  In Act 34, the CPU 101 adds the sales score SN to the score data SNx corresponding to the product code input in the restriction memory RM. The sales score SN is “1” when the multiplier m is input immediately before the product code is input, and “1” when the multiplier m is not input.

  After adding the sales score SN to the score data SNx, the CPU 101 confirms whether the score data SNx exceeds the corresponding limit number RN (Act35). Here, the processing of Act 35 realizes a function of confirming whether the sales amount of the special sale restricted product exceeds the restriction when the special purchase restricted product is included in the product purchased by the customer as one commercial transaction (confirmation means).

  When the score data SNx is equal to or less than the limit number RN, the CPU 101 executes the process of Act36. That is, the CPU 101 sets the status data ST in the status memory SM to “1”.

When the score data SNx exceeds the limit number RN, the CPU 101 executes the process of Act37. That is, the CPU 101 causes the touch panel 22 to display a warning screen 50 (see FIG. 8) for warning that the number of sales of the limited number of products exceeds the limited number. At this time, the CPU 101 reads the normal unit price and the special sale unit price of the product from the limited memory RM, and displays the normal unit price and the special sale unit price on the warning screen 50 together (Act 38). Here, the processing of Act 37 and Act 38 realizes a function of notifying the operator of the normal price and the sale price of the product when the sales amount of the sale restricted product exceeds the limit (notification means).
The CPU 101 confirms whether the value obtained by subtracting the sales point SN from the point data SNx is smaller than the limit number RN (Act 39). If it is smaller (YES in Act 39), the CPU 101 executes the process of Act 41 after executing the process of Act 40. If not smaller (NO in Act 39), the CPU 101 executes the process of Act 41 without executing the process of Act 40. In Act 40, the CPU 101 causes the button image of “low cost” to be displayed over the warning screen 50. In Act 41, each button image of [Normal] and [Cancel] is displayed on the warning screen 50 in an overlapping manner.

  The CPU 101 waits for any button image displayed on the touch panel 22 to be touch-inputted (Act 42, Act 43, Act 44). That is, the CPU 101 confirms whether or not the [cheap] button image has been touch-inputted (Act 42). If the touch input has not been performed (NO in Act 42), the CPU 101 confirms whether or not the [normal] button image has been touch-input. (Act 43) If no touch input has been made (NO in Act 43), the CPU 101 confirms whether or not the [Cancel] button image has been touch-input (Act 44). If the Act 40 process for displaying the [cheap] button image has not been executed, the process of Act 42 for confirming whether the [cheap] button image has been touch-inputted is omitted.

  When the “cheap” button image is touched (YES in Act 42), the CPU 101 sets the status data ST in the status memory SM to “1” (Act 45). When the [normal] button image is touch-input (YES in Act 43), the CPU 101 sets the status data ST to “2” (Act 46). When the [Cancel] button image is touch-inputted (YES in Act 44), the CPU 101 sets the status data ST to “3” (Act 47). The processing order of Act42, Act43, and Act44 is not limited to this, and can be changed as appropriate.

  Thus, if the status data ST is set to “1”, “2”, or “3” in Act 36, Act 45, Act 46, or Act 47, the CPU 101 ends the number limiting process.

  When the number limiting process ends, the CPU 101 checks the status data ST (Act 14). When the status data ST is other than “3”, ie, “0”, “1”, or “2” (NO in Act 14), the CPU 101 proceeds to the process of Act 7. On the other hand, when the status data ST is “3” (YES in Act 14), the CPU 101 ends the process for inputting the product code.

  FIG. 7 is a flowchart specifically showing the procedure of the sales data generation process. When the sales data generation process is entered in Act 12, the CPU 101 checks the status data ST (Act 61, Act 64).

  When the product specified by the input product code, that is, a so-called sales product (a product purchased by a customer) is not a sale-restricted product, the status data ST is “0”. On the other hand, when the sale product is a sale-restricted product, the status data ST becomes “1”, “2”, or “3” by the above-described number restriction process. However, when the status data ST is “3”, it is determined as “YES” in the processing of Act 16 and the processing for the input is completed without executing the sales data generation processing. The status data ST is never “3”.

  If the status data ST is “0” (YES in Act 61), the CPU 101 executes the processing of Act 62 and Act 63. If the status data ST is not “0” (NO in Act 61) and is “1” (YES in Act 64), the CPU 101 executes the processes of Act 65, Act 66, and Act 67. If the status data ST is not “0” (NO in Act 61) and is not “1” (NO in Act 64), that is, “2”, the CPU 101 determines Act 68, Act 69, Act 70, Act 71, and Act 72. Execute the process.

  In Act 62, the CPU 101 sets the normal unit price of the acquired product data record 30 as the unit price of the sales product. In addition, the CPU 101 obtains the number of sales items. The sales score SN is “1” when the multiplier m is input immediately before the product code is input, and “1” when the multiplier m is not input.

  In Act 63, the CPU 101 multiplies the normal unit price specified in the process of Act 62 by the number of sales points to obtain the sales price of the sales product. Then, the CPU 101 generates product sales data from the sales price, the product code, product name, and quantity limit flag of the acquired product data record 30, and the normal unit price and the sales point specified in the process of Act62.

  In Act 65, the CPU 101 subtracts the value obtained by subtracting the sales point SN from the point data SNx calculated in the process of Act34 from the limit number RN, and calculates the shortage number SN1 until the sales point SN of the limited sale product reaches the limit number RN. calculate.

  In Act 66, the CPU 101 sets the special sale unit price of the acquired product data record 30 as the unit price of the sales product. Further, the CPU 101 sets the shortage number SN1 calculated in the process of Act 65 as the number of sales items.

  In Act 67, the CPU 101 multiplies the special sale unit price specified in Act 66 by the number of sales points to obtain the sales price of the sales product. Then, the CPU 101 generates product sales data from the sales price, the product code, the product name, and the number limit flag of the acquired product data record 30, and the sale unit price and the sales point specified in the process of Act 66.

  In Act 68, the CPU 101 subtracts the value obtained by subtracting the sales point SN from the point data SNx calculated in the process of Act34 from the limited number RN, and calculates the shortage number SN1 until the sales point SN of the limited sale product reaches the limited number RN. calculate.

  In Act 69, the CPU 101 calculates an excess number SN2 from the limit number RN by subtracting the limit number RN from the score data SNx calculated in the process of Act34.

  In Act 70, the CPU 101 sets the special sale unit price of the acquired product data record 30 as the unit price of the sales product. Further, the CPU 101 sets the shortage number SN1 calculated in the processing of Act 68 as the number of sales items.

  In Act 71, the CPU 101 sets the normal unit price of the acquired product data record 30 as the unit price of the sales product. Further, the CPU 101 sets the excess number SN2 calculated in the process of Act 69 as the number of sales items.

  In Act 72, the CPU 101 multiplies the sale unit price specified in the processing of Act 70 by the number of sales points to obtain the sales amount for the shortage. In addition, the CPU 101 multiplies the normal unit price specified in the process of Act 71 by the number of sales points to obtain an excess sales amount. Further, the CPU 101 adds the sales amount corresponding to the shortage to the sales amount corresponding to the excess to obtain the sales amount of the sales product. Then, the CPU 101 generates merchandise sales data from the sales price, the merchandise code, the merchandise name and the quantity limit flag of the acquired merchandise data record 30, the sales point SN, the normal unit price, and the special sale unit price.

Thus, if product sales data is generated in Act 63, Act 67 or Act 72, the CPU 101 stores the product sales data in the current memory CM (Act 73). Thus, the CPU 101 ends the sales data generation process.
Here, the sales data generation process of Act 10 realizes a function of processing the sales data of the product specified by the specifying means (processing means). Further, the processing of Act 42 to Act 44 of the number selection means realizes a function of accepting selection as to whether or not to proceed with the processing of the product when the sales amount of the special sale restricted product exceeds the limit (selection means).

  When the selection to proceed with the selection is received by selecting the [Normal] button, the CPU 101 processes the sales data at the normal price for the sales amount exceeding the limit of the special sale restricted product. When a selection indicating that the processing is not allowed to proceed is received by selection input of the [cheap] button, the CPU 101 cancels the portion exceeding the limit of the special sale restricted product.

  In the present embodiment configured as described above, a limited quantity sale for selling up to two products BBBB with a normal unit price of 108 yen is being implemented at a special sale unit price of 98 yen, and an attempt is made to purchase four pieces of this product BBBB. Suppose that there is a customer to do. In this case, there are a method of registering the products BBBB one by one and a method of multiply registering four points together.

  First, the case of single item registration will be described. First, when the first item of the product BBBB is registered for sale, the number restriction process is executed, and the product code of the product BBBB, the normal unit price “108 yen”, the special sale unit price “98 yen”, the limited number RN “2”, and The sales number SN “1” is stored in the restriction memory RM. At this time, since the sales point number SN is equal to or less than the limit number RN, the status data ST is “1”. Accordingly, in the sales data generation process, sales data for one item of the product BBBB is generated at a special unit price of 98 yen and stored in the current memory CM.

  Next, when the second item of the product BBBB is registered for sale, the number limiting process is executed, and the sales point SN of the product BBBB in the limit memory RM becomes “2”. Even at this time, since the sales point number SN is not more than the limit number RN, the status data ST is “1”. Accordingly, in the sales data generation process, sales data for one item of the product BBBB is generated at a special unit price of 98 yen and stored in the current memory CM. Note that before the sales data generation processing, the sales data of the first product BBBB is transferred from the current memory CM to the list memory LM.

  FIG. 3 is a registration screen 40 when the product BBBB is registered up to the second point. In this example, one product AAAA having a unit price of 105 yen is registered before the product BBBB. As shown in FIG. 3, in the current area 41, a display indicating that the unit price of the product BBBB has been reduced from the normal unit price “108 yen” to the special sale unit price “98 yen” is displayed. In the detail area 42, an identification mark 421 is displayed in the attribute column for the sales data of the first product BBBB transferred to the list memory LM.

  Next, when the third item of the product BBBB is registered for sale, the number limiting process is executed, and the sales point SN of the product BBBB in the limit memory RM becomes “3”. That is, since the sales number SN exceeds the limit number RN, the warning screen 50 is displayed on the touch panel 22.

  FIG. 8 is a display example of the warning screen 50. In this example, a warning screen 50 is popped up on the registration screen 40. At this time, since the unit price of the product BBBB is not determined, the amount of the current area 41 on the registration screen 40 is 0 yen. The total score and total amount of the total area 43 are also not added for the third item BBBB.

  As shown in FIG. 8, the warning screen 50 displays a message “1 point over” that warns that the sales point SN of the limited number of products exceeds the limited number RN. Further, the special sale unit price of 98 yen and the normal unit price of 108 yen are displayed together on the warning screen 50. Further, button images of [Normal] and [Cancel] are displayed on the warning screen 50. However, since [SNx−SN <RN] is not established in the determination process of Act39, the “cheap” button image is not displayed.

  By checking the warning screen 50, the cashier can know that the sales number SN of the product BBBB has exceeded the limit number RN. Therefore, the cashier informs the customer that the sales point SN of the product BBBB has exceeded the limit number RN and confirms whether or not to purchase the third item. At that time, any cashier can accurately inform the customer of the special unit price up to the limit number RN and the normal unit price exceeding the limit number RN.

  When the customer requests to purchase the third item, the cashier touches the [normal] button image. Then, the status data ST becomes “2”. Therefore, in the sales data generation process, since the shortage number SN1 is “0”, sales data for one item BBBB is generated at a normal unit price of 108 yen and stored in the current memory CM. As a result, the registration screen 40 is updated as shown in FIG.

On the other hand, when the customer requests to return the third item, the cashier touches the [Cancel] button image. Then, the status data ST becomes “3”. Therefore, the sales data generation process is not executed. At this time, the registration screen 40 returns to the state immediately before the third item BBBB is registered, that is, the state shown in FIG.
Thereafter, when the fourth item of the product BBBB is registered for sale, the warning screen 50 is displayed as in the case of the third item. The subsequent processing is the same as in the case of the third point, and a description thereof is omitted here.

  Next, the case of multiplication registration will be described. That is, when the multiplier m = 4 is input by the numeric key and the multiplication key, and the product code of the product BBBB is input, the number limiting process is executed, and the product code of the product BBBB, the normal unit price “108 yen” ”, The unit price“ 98 yen ”, the limited number“ RN = 2 ”, and the sales number“ SN = 4 ”are stored in the limited memory RM. At this point, since the sales number SN has already exceeded the limit number RN, a warning screen 50 is displayed on the touch panel 22.

  FIG. 10 is a display example of the warning screen 50. In this example, a warning screen 50 is popped up on the registration screen 40. At this time, since the unit price of the product BBBB is not determined, the amount of the current area 41 on the registration screen 40 is 0 yen. The total score and the total amount of the total area 43 are not added for the product BBBB.

  As shown in FIG. 10, the warning screen 50 displays a message “2 points over” that warns that the number of sales of the limited quantity product exceeds the limited quantity. Further, the special sale unit price of 98 yen and the normal unit price of 108 yen are displayed together on the warning screen 50. Furthermore, since [SNx−SN <RN] is established in the determination process of Act39, in addition to the [normal] and [cancel] button images, a [cheap] button image is also displayed on the warning screen 50.

  By checking the warning screen 50, the cashier can know that the sales number SN of the product BBBB has exceeded the limit number RN. Therefore, the cashier informs the customer that the sales number SN of the product BBBB has exceeded the limit number RN and confirms whether or not to purchase four items together. At that time, any cashier can accurately inform the customer of the special unit price up to the limit number RN and the normal unit price exceeding the limit number RN.

  When the customer requests to purchase only the limited number of two, the cashier touches the button image of [Inexpensive]. Then, the status data ST becomes “1”. Therefore, in the sales data generation process, sales data for the product BBBB with two sales points is generated at a special unit price of 98 yen and stored in the current memory CM. Sales registration is canceled for two points exceeding the limit. A display example of the registration screen 40 at this time is shown in FIG.

  When the customer requests to purchase all four points, the cashier touches the [normal] button image. Then, the status data ST becomes “2”. Therefore, in the sales data generation process, since the shortage number SN1 and the excess number SN2 are both “2”, the product sales data with a special sale unit price of 98 yen and two sale points, the special sale unit price of 108 yen, and the sale point number is 2. The point sales data is generated, integrated, and stored in the current memory CM. A display example of the registration screen 40 at this time is shown in FIG. As shown in FIG. 12, in the current area 41, product sales data with a special sale unit price of 98 yen and a sales point of 2 points and product sales data with a special sale unit price of 108 yen and a sale point of 2 points are integrated. The displayed information “@ 98 yen × 2, @ 108 yen × 2” is displayed.

  When the customer cancels the purchase of all four points, or when the customer switches to the purchase of only one or three points, the cashier touches the [Cancel] button image. Then, the status data ST becomes “3”. Therefore, the sales data generation process is not executed. A display example of the registration screen 40 at this time is shown in FIG.

  As described above, in the POS terminal 10 according to the present embodiment, when the number of sales of the limited sale products exceeds the limit in one commercial transaction, the warning screen 50 is displayed on the touch panel 22 that is a cashier display.
