Abstract

PURPOSE:To easily confirm the total of the deduction amount of money only by looking at a receipt by printing out the contents of a deduction and discount amount storage part on a print part according to a decision on reduction registration. CONSTITUTION:When an article registration flag 22 is set, a subtotal flag 24 is set and it is decided whether the deduction of a current transaction is registered from the value in a deduction total storage area 25. Then when a numeral is stored in the deduction total storage area 25, the reduction total stored in the deduction total storage area 25 is printed on the receipt by a deduction amount print control means which is an amount print control means. Consequently, the total amount of money after deduction or discount can be known without any troublesome calculation.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to an electronic cash register that prints and issues product data, total amount, etc. on a receipt as a registration result. The present invention relates to an electronic cash register that performs discount registration in which an amount of money is subtracted and registered, and percentage discount registration in which a certain percentage of the unit price is registered by subtracting the amount from the unit price.

(Prior Art) In conventional electronic cash registers, when a discount is applied to a single item, that is, in the case of a single item discount, the discount amount is printed along with the normal unit price. The printing format of the receipt is shown in FIG.

As shown in the figure, the discount amount for each product is printed on the conventional receipt. This allows the customer to know how much the discount has been on each product. However, since the cumulative total of discounts is not printed at all, if you want to know the total discount, you have to calculate it again using a calculator, which is a hassle. In addition, as a method of selling products, there is a flat rate discount of 5% on all purchased products to specific customers, that is, a lump-sum percentage discount, but even in this case, similar to the receipt mentioned above, there is a percentage discount on each product. It was easy to see what percentage each item was discounted, but it took time to find out the total amount discounted.

(Problems to be Solved by the Invention) As mentioned above, in conventional electronic cash registers, the discounted amount or discount rate for each item is printed. It is inconvenient for customers who want to know the total discount amount because it is not easy to know how much the discount has been given in total, and it is also inconvenient for customers who want to know the total discount amount. However, since the discount amount and discount rate are printed on each product, it is difficult to read the receipt, and the receipt itself is also long.

In view of the above-mentioned problems of the prior art, in the first aspect of the present invention, when discount registration or percentage discount registration is performed, the total amount of the discount or percentage discount is printed at the end of registration, and the total amount of the discount or percentage discount is easily printed. The purpose of the second
The invention focuses on the fact that the discount rate is constant for lump-sum percentage discounts, and identifies that percentage discount registration has been performed without printing the discount rate for each product. To provide an electronic cash register that prints a cash register mark and issues a short and easy-to-read receipt.

[Structure of the invention]

(Means for solving the problem) (1) It has an input means, and registers the product based on the product code corresponding to the product inputted from the input means, and outputs the product data to the printing section. and further discount a predetermined amount or an amount equivalent to a predetermined percentage of the unit price based on an instruction from the input means to register the product indicated by the product code input by the input means as a discount. Discount registration is performed in an electronic cash register that performs a discount registration process and outputs the total amount per customer to the printing unit and prints it on the receipt based on a registration completion instruction input from the input means. an amount totaling means for cumulatively storing the discount amount for each discount amount in a discount amount storage unit; and a registration determining means for determining whether discount registration has been performed in response to an instruction to end the registration by the input means. and an amount printing control means for printing out the contents of the discount amount storage section on the printing section based on the registration discriminating means discriminating that a discount registration has been performed. formula cash register.

(2) having an input means, registering the product based on the product code corresponding to the product input from the input means, outputting the product data to the printing unit to print on the receipt, and further inputting the If the input means has given a bulk percentage discount registration instruction to discount the products indicated by the product code input by the input means by a predetermined percentage, the predetermined discount registration process is performed and the registration from the input means is completed. In an electronic cash register that outputs the total amount per customer to the printing unit and prints it on the receipt based on an instruction input, the discount amount is accumulated and stored in the discount amount storage unit each time a discount registration process is performed. a discount amount aggregation means; a mark printing control means for printing out the product data and mark data indicating that the discount is registered on the printing unit each time a discount registration process is performed; a discount determining means for determining whether a discount has been registered in response to the termination instruction; and a discount amount determined based on the discount determining means having determined that a discount has been registered. 1. An electronic cash register comprising: discount amount printing control means for printing out the contents of the storage section on the printing section.

(Operation) In the first invention, the discount amount is stored cumulatively each time a discount registration is performed, and in response to an instruction to end the registration,
By printing out the total discounted amount on the printing unit, the total discounted amount is printed on the receipt.

In the second invention, when registering a bulk percentage discount, the total discount amount is stored, and mark data indicating that the discount is registered is added to the receipt together with the product data each time the discount registration process is performed. Print out. Then, in response to an instruction to end the registration, the total discount amount is printed out on the printing unit.

It consists of a discount key 18 that is input later, a subtotal key 19 that is input when calculating the registration total, and a deposit/cash total key (closing key) 20 that is input when completing customer registration.

FIG. 3 is a configuration diagram of the main memories used in this embodiment within the RAM 4. The RAM 4 stores a single item table 21 for managing sales for each product, a product registration flag 22 that indicates that the product has been registered, a lump sum percentage discount flag 23 that indicates that a -bulk percentage discount has been declared, and a subtotal key. A subtotal flag 24 indicating that it has been input; - a discount total storage area 25 that stores the total discount amount within a transaction; - a customer total storage area 26 that stores the total registered amount of the transaction; input from the numeric keypad 13 It is composed of a number storage area 27 for storing the data entered, and a lump-sum percentage discount rate storage area 28' for storing the discount rate input when the lump-sum percentage discount is declared. Also, the single table 21 is PLU
PLU number area 211 for storing numbers; name area 212 for storing product names used for printing and display;
It consists of a unit price area 213 that stores unit prices, and a cumulative sales amount area 214 that stores cumulative product sales.

FIG. 4 is a flowchart showing the processing of this embodiment. This flowchart starts when there is manual input from the keyboard 2. First, it is determined what the input key is. Here, if it is a PLU key, the process from step 101 is executed, if it is a discount key, the process from step 113 is executed, and if it is a -batch percentage discount key, the process from step 119 is executed.
Execute the following processing. Furthermore, if it is a subtotal key, the process from step 124 is executed, if it is a closing key, the process from step 131 is executed, and if it is a numeric keypad, the process from step 13 is executed.
7 Execute the following processing. If it is not one of these keys, other processing will be performed in step 139.

If it is determined in step 100 that it is PLU, the subtotal flag is cleared in step 101. This is to prepare for additional registration after the subtotal. In step 102, a product registration flag indicating that product registration has started is set, and in step 103, it is determined whether a bulk percentage discount has been set. - If the bulk percentage discount flag is set, it is a registration of a lump sum percentage discount, so in step 104, the registered amount and value are calculated from the rate stored in the lump percentage discount rate storage area and the unit price corresponding to the input PLU number. Calculate the withdrawal amount. In step 105, which is a discount amount aggregation means, the discount amount is stored in a cumulative discount storage area;
In step 106, the registered amount is accumulated and stored in the per-customer total storage area or the like. In step 107, the registered amount is displayed, and in step 108, which is a mark printing control means, product data such as the product name, unit price, and a lump sum discount mark are printed on the receipt, and the process ends. Furthermore, if the -batch percentage discount flag is not set, it is a normal registration, and the registered amount is accumulated and stored in the per-customer total storage area or the like in step 109. In step 110, the registered amount is displayed, and in step 1], product data such as product name and unit price are printed on the receipt, and the process ends.

If it is determined in step 112 that a discount key has been input, then in step 113 it is determined from the bulk percentage discount flag 23 whether a declaration of a bulk percentage discount has already been made. This is to prohibit double discounting. -Bulk percentage discount frac 2
If 3 is set, it means that the bulk percentage discount process has already been carried out, and error processing is performed in step 117. - If the direct pull flag 23 is not set, step 11
In step 4, it is determined by the product registration flag 22 whether the product has been registered before the discount key 18 is input. If the product registration flag 22 is set, the product has been registered, so in step 115 the discount amount that would have been entered using the numeric keypad 13 is stored in the discount cumulative storage area, and in step 116 the value is recorded on the receipt. Print the withdrawal amount and end the process. If the product registration flag 22 is not set, error processing is performed in step 117.

Error handling involves displaying a message indicating an operational error and sounding a buzzer. This represents the process of returning to the state before the error operation when the clear key is input.

This forces the operator to restart the operation from the state before the error occurred.

Step 105 and step 115 are amount totaling means.

If it is determined in step 11.8 that the bulk percentage discount key 17 has been input, it is determined in step 119 whether the product has already been registered. If the product registration flag 22 is set, the product has already been registered, so error processing is executed to invalidate the input of the bulk percentage discount key 17. If the product registration flag 22 is not set, the bulk percentage discount 23 is set in step 120, and the process waits for input of the % key 15 in step 121. % key 15
When inputted, in step 122, the value inputted using the numeric keypad I3 and stored in the number storage area 27 is stored in the bulk percentage discount rate storage area 28, and the process is terminated.

If it is determined in step 123 that the subtotal key 19 has been input, it is determined in step 124 whether the product has been registered based on the product registration flag 22.

If the product registration flag 22 is not set, it means that the product has not been registered yet, so the process ends.

If product registration flag 22 is set, step 1
Subtotal flag ゛24 indicating that subtotal operation was performed at 25
is set, and in step 126, which is a registration determining means and a discount determining means, it is determined from the value in the discount total storage area 25 whether a discount has been registered for the current transaction.

If the value in the discount total storage area 25 is 0, there was no discount processing in this transaction, and the process proceeds to step 128. If a numerical value is stored in the discount total storage area 25, the amount printing control means and the discount amount printing control means print the discount total stored in the discount total storage area 25 at step 127. to be printed. Step 12
At step 8, the subtotal amount, tax amount, and total amount are printed, and at step 129, the total amount is displayed, and the process ends.

If it is determined in step 130 that the close key 20 has been input, it is determined in step 131 whether subtotal processing has been performed based on the subtotal flag 24. If the subtotal flag 24 is not set, the subtotal processing has not yet been completed, and the processing is terminated. If the subtotal flag 24 is set, in step 132 the value stored in the per-customer total storage area 26 is subtracted from the value entered using the numeric keypad 13 and stored in the number storage area 27 to calculate change. 1
33 to display the change. In step 134, deposit money, change, etc. are printed, and in step 135, various flags,
Discount total storage area 25, -Customer total storage area 26, -
The bulk percentage discount rate storage area 28 is cleared and the process ends.

If it is determined in step 136 that an input has been made using the numeric keypad 13, the input value is displayed in step 137, and stored in the numeric storage area 27 in step 138, and the process ends.

FIG. 5 shows a printed example of a receipt output in this embodiment. (1) is a printing example for single item discount, and (2) is -
This is an example of printing a lump sum discount. The operation of this embodiment will be explained using this printing example.

As for key operations, the PLU number is input using the numeric keypad and the PLO key is input.When discounting a single item, the discount amount is then input using the numeric keypad and the discount key is input. In addition, when performing a bulk percentage discount, enter the bulk percentage discount key before starting product registration, specify the percentage discount to be applied using the numeric keypad, and enter the % key. .

Assume that a customer now purchases a calculator, punch, and notebook. First, single item discounts will be explained with reference to (1). The operator inputs the PLU number 001 of the calculator from the keyboard. Dentaku and the unit price of 5,000 yen will be printed on the receipt. Next, enter the discount amount of 300 and input the discount key, and the discount amount of 300 will be printed as -300. Below, punches will be discounted by 40 yen, and notebooks will be discounted by 100 yen. By inputting the subtotal key, the total discount amount of 440 is printed. The printing is (
It will be like a). In addition, the subtotal amount is 8,520 yen, and the tax amount is 2.
55 yen, printing a total of 8,775 yen. Assuming that the customer paid 9,000 yen, he enters 9,000 and enters the closing key. The deposit amount 9000 and change 225 are printed.

Next, lump-sum percentage discount will be explained with reference to (2).

The operator inputs a bulk percentage discount key in response to the fact that the customer has brought a service card or the like, and sets the discount rate. Assume that a one-time discount of 5% is given. -Enter the bulk percentage discount key and enter 5 to %
Enter the key. Then, input the PLU number 001 of the calculator from the keyboard. Dentaku and unit price 5 on the receipt
000 yen and a blanket percentage discount mark is printed to indicate that a percentage discount is applied across the board. The printout will look like (a). Do the same for punches and notebooks below, and enter the subtotal key to calculate the discount amount of 448.
Print. Furthermore, the subtotal amount of 8,512 yen, the tax amount of 255 yen, and the total amount of 8,767 yen are printed. Assuming that the customer paid 9,000 yen, he enters the number 9,000 and enters the closing key. The deposit amount 9000 and change 233 are printed.

In this way, according to this embodiment, the total amount of discounted or percentage discounted amounts can be known without any troublesome calculations.

What's more, - for products that have been given a bulk discount -
Since the mark indicating the bulk percentage discount is printed together with the product data, customers can easily know that the bulk percentage discount has been applied. This method of not printing the discount rate for each product is used in transactions where the customer naturally knows the discount rate, such as giving a fixed percentage discount for all products, i.e. when the discount rate is constant. It is valid.

In the present embodiment, the lump-sum percentage discount is calculated and totaled for each product registration, but it may also be calculated and printed when the subtotal key is input. Further, the discount mark is not limited to this embodiment. Various modifications can be made without departing from the gist of the invention.
