Description

  The present invention relates to a cash register, and more particularly, to a cash register that calculates a total amount by performing a discount from a subtotal amount of an input commodity amount.

  Conventionally, from the viewpoint of promoting product sales, various techniques have been disclosed for cash registers that perform discounts or discounts on subtotals of product amounts for the purpose of granting benefits to customers.

  For example, in Patent Publication 1 (Japanese Patent Laid-Open No. 2004-220426), a greater privilege (discount rate) is given to a customer who has purchased more products according to the accumulated product purchase amount for each customer or its rank. The technology to grant is disclosed.

JP 2004-220426 A

  With conventional cash registers, the operator may need to perform complicated operations such as sending and receiving a large number of coins with the customer to pay for the price or return the change at the time of payment. Was lowering.

  Technology for accepting payments with point cards has been built to increase the efficiency of cash register operations, but if the customer forgets the number of points accumulated on the point card, the remaining point amount is examined and presented to the customer. In some cases, an operator is required for this operation, which may lead to a decrease in the efficiency of the cash register operation.

  The present invention has been devised in view of such circumstances, and its purpose is to simplify the operation of the cash register operator by reducing the number of change coins relative to the purchase amount while promoting the sale of goods. , And acquiring customers to become repeaters.

  The cash register according to the present invention includes a receiving unit that receives an input of a product price, a first calculation unit that calculates a subtotal of the input product price, and customer identification information that identifies a customer who is a transaction target The first acquisition means for acquiring the information, the history storage means for storing the history of the product purchase price for each customer, and the customer that is the transaction target from the history storage means based on the customer specifying information acquired by the first acquisition means Based on the second acquisition means for acquiring the total of the product purchase amount, the limit amount information storage means for storing the deduction amount information for the total purchase amount of the product, and the total purchase amount of money acquired by the second acquisition means The total amount is calculated by subtracting the fraction from the subtotal amount to the deduction limit amount acquired by the third acquisition means and the third acquisition means for acquiring the deduction limit amount from the limit amount information storage means. And a second calculating unit that.

  In the cash register of the present invention, the history storage means further stores the last purchase date for each customer specifying information, and the second calculating means is the final associated with the customer specifying information acquired by the first acquiring means. It is preferable to calculate the total amount by subtracting the fraction from the subtotal amount to the deduction limit on the condition that the predetermined period has not elapsed since the purchase date.

  Further, the cash register of the present invention adds the total amount for the customer specifying information acquired by the first acquisition unit to the history storage unit, and the latest purchase date calculated by the second calculation unit by the second calculation unit. It is preferable to further include an updating means for updating the date.

  Further, in the cash register of the present invention, the history storage unit stores the total sum for each customer specifying information, and in the calculation of the total sum, the history storage means applies the condition that a certain period of time has elapsed since each total amount was stored. The total amount is invalidated, and the second calculation unit preferably determines the deduction limit amount according to the total sum of the total amount associated with the customer identification information acquired by the first acquisition unit.

  In the cash register of the present invention, the second calculation means calculates the total amount by subtracting the fraction from the subtotal amount to the subtraction limit on condition that the subtotal amount is equal to or greater than a specific amount.

  According to the present invention, the total amount is calculated by subtracting a fraction less than the predetermined amount from the subtotal amount of the commodity amount. Thereby, the number of change coins that the cash register operator gives to the customer can be reduced. Therefore, the operation of the cash register operator is simplified by reducing the number of change coins relative to the purchase amount.

  Moreover, since the discount amount can be changed in accordance with the purchase amount, customers who become repeaters can be acquired.

  Table 1 shows an example of the contents of the fractional value subtraction table 530.

  As understood from Table 1, in the rounded value discount table, a discount rank is associated with one of A to C based on the range of the accumulated amount of purchases in the previous year, and each discount rank has a maximum value. A discount (499 yen, 99 yen or 9 yen) is associated.

[Sales registration process at POS terminal]
Next, the sales registration process executed in the POS terminal 200 for calculating the total amount when the customer purchases the product will be described with reference to FIGS. 5 to 8 which are flowcharts of the process.

  First, the operator or customer of the POS terminal 200 sets a customer card on the card reader 206. In response to this, the CPU 201 acquires a customer number from the card reader 206 and advances the process to step S20.

  In step S20, the CPU 201 accesses the database 500 via the host computer 100, reads the customer information data associated with the customer number acquired in step S10 from the customer information database 510, and stores it in the memory 202. The process proceeds to S30.

  In step S30, the CPU 201 causes the display 203 to display the customer information data read in step S20 on the display 203 (or a part thereof (for example, only the customer number and the most recent purchase date)), and advances the process to step S40. .

  In step S40, the CPU 201 accepts an input of a product code from the barcode reader 207 or the keyboard 204, and advances the process to step S50. At this time, the operator (or customer) holds the barcode attached to the product that the customer wishes to purchase over the barcode reader 207 or inputs the product code to the keyboard 204.

  In step S50, the CPU 201 accesses the product information database 520 via the host computer 100, reads product information data associated with the product code acquired in step S40 from the product information database 520, and stores it in the memory 202. Then, the process proceeds to step S60.

  In step S60, the CPU 201 causes the display 203 to display the product information data (or part thereof) acquired in step S50, and advances the process to step S70.

  In step S70, the CPU 201 calculates the subtotal amount for all the products registered in the reading memory 202 in step S50 after starting the current sales registration process, and displays it on the display 203, and the process proceeds to step S80. Proceed.

  In step S80, it is determined whether or not the input of the product code in step S40 has been completed for all the products that the customer desires to purchase. If it is determined that the product code has not yet been completed, the process returns to step S40 and ends. If it is determined that the process has been performed, the process proceeds to step S90.

  In step S80, the CPU 202 determines, for example, whether or not a subtotal key included in the keyboard 204 has been pressed. If it is determined that the subtotal key has been pressed, the CPU 202 proceeds to step S90 and proceeds to the next step without pressing the subtotal key. If the product code is input, the process returns to step S40 to accept the input of the product code.

  Referring to FIG. 6, in step S90, CPU 202 reads the latest purchase date data for the customer number read in step S10 from customer information database 510 via host computer 100, and advances the process to step S100.

  In step S100, the CPU 202 determines whether or not the customer number read in step S10 is the first purchase this year, and if so, proceeds to step S110 and determines that it is not. The process proceeds to step S130.

  In step S100, the CPU 202 determines that the purchase is the first purchase of the current year if the latest purchase date is for the previous year, and otherwise determines that the purchase is not the first purchase of the current year.

  In step S110, the CPU 202 stores the customer information database 510 via the host computer 100 so that the value of the current year purchase cumulative amount 516 for the customer whose customer number has been read in step S10 is transferred to the previous year cumulative purchase amount 515. Update the process and proceed to step S120.

  In step S120, the CPU 202 clears the value of the total purchase amount 516 of this year for the customer whose customer number is read in step S10 in the customer information database 510 via the host computer 100 (sets it to 0 yen). Update and proceed to step S130.

  In step S130, based on the latest purchase date data read in step S90, the CPU 202 determines whether or not the current purchase has passed one year or more from the latest purchase date, and if so, step S220. If not, the process proceeds to step S140.

  Referring to FIG. 7, in step S140, CPU 202 accesses database 500 via host computer 100, whereby the previous year cumulative purchase amount 516 for the customer whose customer number is read from customer information database 510 in step S10. Is read, and the process proceeds to step S150.

  In step S150, the CPU 202 determines a discount rank for the customer whose customer number has been read in step S10.

  The CPU 201 determines the discount rank for each customer number by referring to the fractional discount table 530 based on the previous year's accumulated purchase amount 515.

  Returning to FIG. 7, in step S150, the CPU 201 determines the discount rank as A if the customer number read in step S10 is 50,000 yen or more, and if it is 10,000 yen or more and 49999 yen or less, the value is determined. The discount rank is determined as B, and if it is 9999 yen or less, the discount rank is determined as C.

  If it is determined that the discount rank is A, the CPU 21 determines in step S160 whether or not the subtotal amount of sales finally calculated in step S70 is less than 10,000 yen. If so, the process proceeds to step S180. If the process proceeds and if it is determined that it is 10,000 yen or more, the process proceeds to step S170.

  In step S170, CPU21 sets the remainder which divided the said sales total amount by 500 yen as a discount amount, and advances a process to step S230.

  In step S180, the CPU 201 determines whether or not the subtotal sales amount is less than 1000 yen. If so, the process proceeds to step S200, and if it is determined to be 1000 yen or more, the process proceeds to step S190. Proceed.

  In step S190, the CPU 201 sets the remainder obtained by dividing the subtotal sales amount by 100 yen as the discount amount, and proceeds to step S230.

  In step S200, the CPU 201 determines whether or not the subtotal sales amount is less than 100 yen. If so, the process proceeds to step S220, and if it is determined to be 100 yen or more, the process proceeds to step S210. Proceed.

  In step S210, the CPU 201 sets the remainder obtained by dividing the subtotal sales amount by 10 yen as a discount amount, and proceeds to step S230.

  In step S220, the CPU 201 sets the discount amount to 0 yen and advances the process to step S230.

  In step S230, the CPU 201 causes the display 203 to display the discount amount set in steps S170, S190, S210, and S220, and proceeds to step S240.

  In step S240, the CPU 201 calculates the total amount by subtracting the discount amount set in steps S170, S190, S210, and S220 from the sales subtotal amount calculated last in step S70, and displays it on the display 203. The process proceeds to step S250.

  In step S250, the deposit key input is accepted, and the process proceeds to step S260.

  In step S260, the deposit received in step S250 is displayed on display 203, and the process proceeds to step S270.

  In step S270, the amount of change is calculated by subtracting the total amount calculated in step S240 from the deposit input in step S250, displayed on the display 203, and the process proceeds to step S280.

  In step S280, the CPU 201 causes the printer 205 to print a receipt for the current transaction, and proceeds to step S290.

  In step S290, CPU201 updates the data of customer information database 510, and ends processing.

  In the update of the database in step S290, for the customer number input in step S10, the cumulative amount is updated so that the total amount calculated in step S240 is added to the current year purchase cumulative amount. In addition, the cumulative number of visits is updated by one. The most recent purchase date is updated on the date when this process is executed.

FIG. 9 shows an example of the receipt printed in step S280.
Referring to FIG. 9, in the receipt 900, general advertisement information such as “ABC Denki” is printed at the top, and information 901 about each purchased product is printed thereunder. In the information 901, for each product, the product name, the score of the product, and the unit price are included as the product information data read in step S50.

  In addition, the receipt 900 includes the sales subtotal amount 902 calculated last in step S70.

  The receipt 900 also includes a discount amount 903 set in steps S170, S190, S210, and S220, a total amount 904 calculated in step S240, a deposit amount 905 input from the operator in step S250, and a step. The change amount 905 calculated in S270 is shown.

  In the present embodiment described above, as shown in Table 1, a maximum discount amount is set for each customer discount rank. Here, as described in steps S170, S190, and S210, the maximum discount amount corresponds to which deduction limit amount is the discount amount. In other words, in Table 1, if the discount rank is A, the discount is performed up to a maximum of 499 yen, which is equivalent to the fractional sales amount of 500 yen or less being the discount amount.

  Further, in the present embodiment described above, the customer information database 510 stores the date (the latest purchase date 518) when the product was last purchased at the store for each customer number. In the system according to the present embodiment, when a certain period (for example, 2 years or 3 years) has passed since the most recent purchase date 518, the above-mentioned fractional discount on the purchase price is not performed. Can do.

  Further, in this embodiment, the discount amount is not only based on the rank determined by the fractional discount table for the customer number that is the target of the product settlement, but also based on the subtotal sales amount at that time Have been calculated (steps S160, S180, and S200). Specifically, according to the fractional discount table, A rank customers can discount up to 499 yen, B rank customers can discount up to 99 yen, C rank Customers can discount up to 9 yen. That is, it is possible to reduce the fraction of the amount of money of 500 yen or less, 100 yen or less, or 10 yen or less, respectively. However, even if the customer is ranked A, if the sales subtotal amount is less than 10,000 yen (when YES is determined in step S160), it is determined whether the sales subtotal amount is 1000 yen or more. (Step S180) If it is 1000 yen or more, a fraction of up to 99 yen, that is, 100 yen or less is set as the discount amount (Step S190).

[Modifications, etc.]
In the present embodiment described above, the first calculation unit 211, the second calculation unit 212, the first acquisition unit 213, and the second acquisition unit 214 are recorded in the memory 202 or the like by the CPU 101, respectively. This is realized by executing the program. As a general trend, various program modules are prepared as a part of the computer operating system, and the application program is called up when necessary in a predetermined arrangement to proceed with processing. In such a case, the software itself for realizing the merchandise sales system of the present embodiment does not include such a module, and the merchandise sales system is realized only when the computer cooperates with the operating system. However, as long as a general platform is used, it is not necessary to distribute software including such modules, and the software itself not including these modules and the recording medium storing the software (and the software distributes on the network). Data signal) can be considered to constitute the embodiment.

  In the present embodiment, the presence / absence of the discount and the amount of the discount are determined based on the purchase history of the customer.

  Specifically, the rank for the fractional discount is determined according to the accumulated purchase amount of the previous year, and the discount amount is determined according to the rank. For example, a case where a customer of rank A and a customer of rank B make purchases and the subtotal amount of each of the products of both is 23850 yen is taken as an example. For customers with rank A, the discount amount is the fraction of the subtotal of 500 yen or less. Therefore, the discount amount is 350 yen. On the other hand, for customers of rank B, the discount amount is a fraction of 100 yen or less of the subtotal. Therefore, 50 yen is set as the discount amount.

  In the present embodiment, the accumulated purchase price for the previous year is deleted by updating the accumulated purchase price for the previous year in step S110. As a result, the accumulated purchase price of the customer is invalidated after a certain period.

  In the present embodiment, according to steps S130 and S220, if the most recent purchase date (last purchase date) is one year or more before the present, discounting based on the purchase history is not performed.

  In the customer information database 510, if the latest purchase date is one year or more before the current date, that is, if the customer number for processing has not been updated based on the purchase for one year or more. In step S110, instead of updating the previous year's cumulative purchase price with the previous year's cumulative purchase price, update the previous year's cumulative purchase price with 0 yen and invalidate the previous fiscal year's cumulative purchase price. Also good.

  Further, the current purchase amount is updated each time the sales registration process is executed. In addition, in the customer information database, the CPU 101 records the total amount of each time of the sales registration process together with the date when the processing is executed separately from the current year's cumulative purchase amount, An expiration date may be set for configuring. In other words, if a customer has an expiration date of 3 months and purchases 500 yen in May and purchases 1000 yen in July, the total purchase amount for this year is 1500 yen. However, in September, since three months have passed since the purchase in May, the amount of the purchase is invalidated, and the cumulative purchase amount this year is set to 1000 yen .

  In the present embodiment described above, the information stored in the database 500 can be stored in both terminals regardless of whether the POS terminal 200 and the POS terminal 300 are installed in the same store or in different stores. It can be shared and used by both parties.

  Further, the database 500 can be prepared for each POS terminal, and customer information and product information can be used at each terminal such as each store.

  The POS terminal 200 can also be used as the host computer 100 or the database 500. That is, the storage contents of the database 500 may be stored in a recording medium that can be accessed by the CPU 202 of the memory 202 or the POS terminal 200 and can be attached to and detached from the terminal. In this case, the POS terminal 300 accesses the product information database 520 and the customer information database 510 in the POS terminal 200 by accessing the POS terminal 200, and performs the sales registration processing described with reference to FIGS. Execute.

  In the present embodiment, the database 500 stores a customer information database 510 that associates the previous year's cumulative purchase amount 515 for each customer number, and a fractional discount table 530 that associates the maximum discount amount according to the range of the previous year's cumulative purchase amount. A storage device is configured to store, for each piece of customer specifying information, information for specifying a deduction limit amount for the fraction subtracted from the subtotal amount calculated by the first calculating unit 211. Note that the maximum discount amount of “499 yen”, “99 yen”, and “9 yen” in the present embodiment is information that specifies the fractional amount value from which the fraction is subtracted, such as 500 yen or less, 100 yen or less, or 10 yen or less, respectively. is there. Then, the second acquisition unit 214 acquires a discount rank that specifies the maximum discount amount from the database 510, and determines which subtraction limit is subtracted (steps S140 to S210).

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
