Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a product sales data processing device that can perform discount registration processing.

[Prior Art] Conventionally, when discounting a registered amount, a method has been used in which a predetermined amount is discounted when the total amount of receipts issued by a product sales data processing device exceeds a predetermined amount.

[Problems to be solved by the invention] However, with this method, the customer has to manage the receipts and when the total of several receipts exceeds the specified amount, the customer has to bring the receipt to give a discount. Not only was management troublesome, but even when opening a store, multiple receipts brought in by customers had to be added up and verified, making the process cumbersome.

Therefore, the present invention aims to provide a product sales data processing device that automatically performs discount processing based on a memory card and the registered total price, eliminating the need for customers to manage receipts and simplifying the work. It is.

Another object of the present invention is to provide a product sales data processing device that can selectively issue either a discount receipt or a discount ticket according to a customer's request by key selection, thereby improving customer service.

[Means for Solving the Problems] The present invention provides a product sales data processing device that registers input product sales data and issues a receipt.
As shown in FIG. 1, a card reader/writer b that reads and writes amount data to and from a removable memory card a, and a customer total memory C that stores the total amount of money recorded for one customer. An amount memory d that stores the amount data read from the memory card a by the card reader/writer b, a discount amount setting memory e where the υ1 discount amount is set, a discount amount setting memory f where the discount amount is set, and a discount amount setting memory f where the discount amount is set. When key q is operated, total amount of customer total memory C and amount memory d
and compares whether or not the added amount is larger than the discount prescribed amount in the discount prescribed amount setting memory e, and the comparison means determines that the added amount is larger than the discount prescribed amount. Then, the total discount amount obtained by subtracting the discount amount in the discount setting memory f from the total amount in the customer total memory C is added by the discount receipt issuing means j, which prints out the discount amount using the printer i and issues a receipt, and the comparison means. The amount writing means is provided with an amount writing means for calculating the difference when the amount is determined to be larger than the specified discount amount and having the card reader/writer b write the difference into the memory card a.

Further, according to the present invention, a discount key and a ticket issue key are provided so that when a discount is available, it is possible to select whether to issue a discount receipt or a discount ticket.

[Function] In the present invention having such a configuration, the amount registered in the past is written in the memory card a, and when the closing key is operated, the total amount registered this time and the amount in the memory card a are If the additional amount is larger than the discount prescribed amount set in the discount prescribed amount setting memory e, subtract the discount amount in the discount amount setting memory f from the total amount in the customer total memory C to find the total amount of deduction, and calculate it. A printer 1 prints out a receipt and receives payment from the customer. Further, the discount prescribed amount in the discount current fixed amount setting memory e is subtracted from the added amount of the total amount registered this time and the amount on the memory card a, and the result is written in the memory card a so that it can be used for the next registration.

In addition, a discount key and a ticket issue key are provided, and when the discount key is operated, the discount amount in the discount amount setting memory f is subtracted from the total amount in the customer total memory C to obtain the total discount amount, and the total discount amount is printed on the receipt by the printer i. Print it out and receive payment from the customer. When the ticket issuer 1 key is operated, a normal receipt is issued, and then a discount ticket with the discount amount in the discount amount determination memory f is printed out and handed to the customer.

[Embodiments] Hereinafter, practical examples of the present invention will be explained with reference to the drawings. In this embodiment, the present invention is applied to a single electronic cash register (this will be explained below).

The CPU 21 is connected to the ROM 22, RA to 123, and each controller 24, 25, 27, and 28 by a path line 30.

As shown in FIG. 5, the RAM 23 includes a PLU memory 31 which is a registration memory, a department memory 32 and a transaction memory 33 which are also registration memories, an amount area A 35 and an amount area B 36 which are amount memories, and a customer total memory. 34, a prescribed discount amount lower limit setting memory 37 and a current discount amount upper limit setting memory 38, three discount amount setting memories, a number buffer 40, a discount flag 41, etc. are provided.

The PLU memory 31 is composed of a PLU code setting area, a product name setting area, a DP (department) code setting area, a unit price setting area, a cumulative score storage area, and a cumulative amount storage area.

In the discount prescribed amount lower limit setting memory 37, a lower limit amount for performing discount processing with the discount amounts of the three discount amount setting memories is set, and in the said discount prescribed amount upper limit setting memory 38, the discount amount of the discount amount setting memory 39 is set. An upper limit amount is set for discount processing.

The CPU 21 is programmed to perform the registration process shown in FIG. 6 when there is a key input from the keyboard 1 while the "registration" mode is set with one control switch.

That is, when there is a key input on the numeric key 11, the input data is stored in the numeric buffer 40.

Further, when there is a key input using the PLU key 14, it is checked whether or not there is a PLU code input using the numeric key 11 before that, and if there is no PLU code input, an error is generated. If there is, PLU registration processing is performed. This is based on the PLU code entered.
The corresponding product name, DP code, and unit price are read out from the LU memory 31, the input points are accumulated in the accumulated points storage area, and the amount is accumulated in the accumulated amount storage area. Next, department registration processing is performed. This accumulates points and amounts for each department based on the read DP code. Furthermore, the amount is added to the customer total memory 34. PLU code,
The number of items and the amount are displayed on the display 2, and the item name, unit price, number of items, and amount are printed out on the receipt and journal by the printer 26.

Also, when the deposit/cash total (closing key) 15 key is input, it is checked whether the product has been registered at least once before.
If it does not exist, an error occurs, and if it does, memory processing is performed.

This memory processing accumulates the total amount Y in the customer total memory 34 in the transaction-by-transaction memory 33. Next, card insertion slot 5
Check whether a memory card is inserted in the
If it is not inserted, perform the normal tightening process. In other words, the discount amount P read from the three discount amount setting memories is
0", total amount P - discount amount P, that is, total amount Y
is displayed on the display 2, and printed on the receipt and journal by the printer 26. Also, amount area A3
5. Clear the amount area B36 and customer total memory 34, respectively, and issue a receipt.

If a memory card is inserted, the card reader/writer 29 reads the amount X written on the memory card.
The amount is stored in the read amount area A35. Subsequently, the total amount IY in the customer total memory 34 is added to the amount area A35. Then, the content (X+Y) of the amount area A35 is compared with the lower limit amount N set in the discount prescribed amount lower limit setting memory 37. In this comparison, if N<(X0Y), it is determined that a discount will be given, and a message such as "Discount will be given" is displayed on the display 2, and an interrupt flag 41 is set. If N< (X+Y), it is determined that no discount will be given, and the amount (X+Y) in the amount area A35 is written to the memory card using two card readers/writers. Subsequently, the discount amount is displayed in the discount amount setting memory 2 and printed out on a receipt and journal by the printer 26. Also, amount area A35, amount area B36, customer total memory 3
Clear each of 4 and issue a receipt. If a memory card is inserted into the card insertion slot 5, an operation is performed to return it. That is, the memory card is ejected from the insertion slot 5.

When the v1 pull key 17 is input, it is then checked whether the interrupt flag 41 is set, and if it is not set, an error is made, and if it is set, the total amount Y in the customer total memory 34 is determined. The discount amount P in the discount amount setting memory 39 is subtracted from the discount amount setting memory 39, and the result Q is stored in the amount area B36. At this time, if Q<O, then Q=
Set it to O.

Next, it is checked whether the content (X+Y) of the amount area A35 is smaller than the upper limit amount M of the discount prescribed amount upper limit setting memory 38. That is, (X0Y)-~1<0 or cutinic. If <X0Y)-Mho, the card reader/writer 29 writes the amount "O" into the memory card. If (X-4-Y)-M<O, the result of (X+Y)-N·1 is written to the memory card by the card reader/writer 29.

Next, the discount amount P in the 1-subtraction setting memory 39 is subtracted from the total amount Y in the customer total memory 34, and the resulting discounted total amount is displayed on the display 2, and is printed out on the receipt and journal by the printer 26. do. Also, amount area A35, amount area B36, customer total memory 3
Clear each of 4 and issue a receipt. If a memory card is inserted into the card insertion slot 5, an operation is performed to return it.

Furthermore, when there is a key input from the ticket issuing key 18, it is checked whether the interrupt flag 41 is set or not.
If it is not set, an error is made, and if it is set, it is then checked whether the content (X+Y) of the amount area A35 is smaller than the upper limit amount M of the discount prescribed amount upper limit setting memory 38. That is, it is checked whether (X+Y) -M<O. If (X+Y)-~I<O, the amount "0" is written to the memory card by two card readers/writers. If (X+Y)-M<0, the result of (X+Y)-M is written to the memory card by the card reader/writer 29.

Subsequently, the total amount Y in the customer total memory 34 is displayed on the display 2, and the printer 26 prints out a receipt and a journal to issue a receipt. Subsequently, the discount amount P in the discount amount setting memory 39 is printed out on a receipt by the printer 26, and a discount ticket is issued. Also, amount area A3
5. The amount area 836 and the customer total memory 34 are cleared, and if a memory card is inserted into the card insertion slot 5, the memory card is returned.

In this embodiment having such a configuration, the PLU code attached to the product is entered using the numeric key 11, and then the PLU code is pressed into the PLU key 14.
When operated, PLU registration is performed in the PLU memory 31, and department registration is performed in the departmental memory 32. Also, the registered amount is displayed in the customer total memory 34.
will be added to r3.

Further, the PLU code, number of points, and amount of money registered in the PLU are displayed on the display 2, and the product name, unit price, number of points, and amount of money are printed out on a receipt by the printer 26.

Such a PLU single item registration operation is repeated for all the customer's products, and the customer's total amount Y is stored in the customer total memory 34.

In this state, payment is received from the customer, and at this time the memory card is received from the customer and inserted into the card insertion slot 5.

Then, the user operates the deposit/cash key 15, which is the closing key.

As a result, amount X is read from the memory card and stored in amount area A35.

Further, the total amount Y in the customer total memory 34 is added to the amount area A35. In this way, amount area A35 has (X
+Y) amount will be stored.

In this state, the amount (X+Y) is compared with the lower limit amount N of the discount prescribed amount lower limit setting memory 37. and the amount (X+Y)
is larger than the lower limit amount N, a discount is determined and an interrupt flag 41 is set.

In this state, the selection operation of the discount key 17 or the ticket issue key 18 is performed based on the customer's request. If the customer requests a discount from the current registered amount, the discount key 17 is operated. Then, the discount amount P is subtracted from the total amount Y, and if the result is "0" or less, it is set as rOJ. Furthermore, the upper limit amount M in the discount prescribed amount upper limit setting memory 38 is subtracted from the amount (X0Y), and it is checked whether the result is smaller than rOJ. If it is smaller, write "O" to the memory card, and if it is larger than [OJ, write the result to the memory card.

Then, the total amount after discount, which is obtained by subtracting the discount amount P from the total amount Y, is printed out on a receipt and a receipt is issued. For example, if you register one product A with a unit price of 1,000 yen and three products B with a unit price of 1,500 yen, and there is a discount of 500 yen, a receipt will be issued as shown in Figure 7. Become.

That is, the total amount (a) is followed by the discount amount (c), and finally the total amount after discount (c).

Further, when a customer requests a discount ticket, the ticket issuing key 18 is operated. Then, the upper limit amount M in the discount prescribed amount upper limit setting memory 38 is subtracted from the amount (X0Y), and it is checked whether the result is smaller than "O". If it is smaller, write "0" to the memory card and write "o" again.
If it is larger, the result is written to the memory card.

First, the total amount Y in the customer total memory 34 is printed out on a receipt and the receipt is issued 11.

Subsequently, the discount amount stored in the discount amount setting memory 39, for example, 500 yen, is printed out on a receipt to issue a discount ticket as shown in FIG.

In this way, the customer's past registration data is written to the memory card, and discount judgment processing is performed based on the sum of the amount written on the memory card at the time of current registration and the current total amount. Therefore, past data is stored in the memory card, and customers do not need to manage past receipts. Therefore, the burden on customers can be reduced. In addition, the operator's work becomes easier as there is no need for the customer to receive past receipts and calculate the total amount. Furthermore, by selecting the 1 draw key 17 and the ticket issuing key 18, it is possible to selectively issue either a discount receipt or a discount ticket according to the customer's request, thereby improving the service to the customer. Although the present invention has been described as being applied to a single electronic cash register, the present invention is not necessarily limited to this, and can of course be applied to a so-called POS system in which a plurality of electronic cash registers are centrally controlled.

[Effects of the Invention] As detailed above, according to the present invention, discount processing is automatically performed based on the memory card and the registered total amount, eliminating the need for the customer to manage receipts and simplifying the work. It is possible to provide a product sales data processing device.

Further, according to the present invention, it is possible to provide a product sales data processing device that can selectively issue either a discount receipt or a υj coupon according to a customer's request by selecting a key, thereby improving customer service. .
