Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to an electronic cash register that prints and issues merchandise data and the total amount of money as a registration result on a receipt. The present invention relates to an electronic cash register which performs a discount registration in which the amount of money is subtracted to perform registration processing, and a percentage discount registration in which a certain percentage of the unit price is subtracted from the unit price for registration.

(Prior Art) In a conventional electronic cash register, when a discount is applied to a single item, that is, in the case of a single item discount, the discount amount is printed together with the normal unit price. The print format of the receipt is shown in FIG. As shown in the figure, the discounted amount of money is printed for each product on the conventional receipt. This allows the customer to know how much the discount was applied to each product. However, since the total of the discounts is not printed at all, there was the trouble of having to recalculate the totals of the discounts with a calculator or the like in order to know the total of the discounts. In addition, as a method of selling products, there is a uniform 5% discount for all of the purchased products, that is, a lump sum discount, but even in this case, the percentage discount for each product is the same as for the receipt mentioned above. It prints only what was done, and it is easy to know what percentage of each product was discounted, but it took time to know the total amount of discount.

(Problems to be Solved by the Invention) As described above, in the conventional electronic cash register, the price or the discount rate for each individual item is printed, or the discount rate is printed. It is inconvenient for customers who want to know the total amount of discount because it is not possible to easily know how much the total discount has been discounted. However, since the discounted amount and the discount rate are printed for each product, reading the receipt is complicated and the receipt itself becomes long.

In view of the above problems of the prior art, the present invention easily prints the total amount of the discount or the percentage discount at the end of the registration when the discount registration or the discount discount registration is performed. With the object of providing an electronic cash register capable of knowing the total amount of a discount or a percentage discount, the second aspect of the present invention focuses on the fact that the discount rate is constant for the collective percentage discount, Regarding percentage discount registration, the purpose is to provide an electronic cash register that issues a short and easy-to-read receipt by printing a mark that can identify that the percentage discount registration has been made without printing the discount rate for each product. And

The display controller 8 for controlling the printer, the printer controller 10 for controlling the R / J printer 9, and the signal output I / O port 18 for opening the drawer 11 are connected.

FIG. 2 is a key layout diagram of the keyboard 5. The keyboard 5 is a numeric keypad 13 for entering numerical values such as the amount of money,
Department key 14 to enter the department of the product,% key 15 to enter the discount rate at the time of batch rate discount, PLU key 16 to be used when entering the product by entering the PLU (price lookup) number, Bulk rate discount key 17 to declare a bulk rate discount, discount key 18 to enter after entering the discount amount when performing a single item discount, subtotal key 19 to enter the total registration, one customer It consists of deposit / cash total key (tightening key) 20 and the like to be entered at the end of registration.

FIG. 3 is a block diagram of the main memory in the RAM 4 used in this embodiment. RAM4 is a single item table 21 that manages sales for each product, a product registration flag 22 indicating that product registration has been performed, a batch ratio discount flag 23 indicating that a batch ratio discount has been declared, and a subtotal key is Subtotal flag 24 that indicates that it has been entered, discount total storage area 25 that stores the total discount amount in one transaction, one customer total storage area 26 that stores the total registered amount of one transaction, input from numeric keypad 13 It is composed of a numerical value storage area 27 for storing the stored data, a collective rate discount rate storage area 28 for storing the discount rate input when the collective rate discount is declared, and the like. Also, the single item table 21 has a PLU number area 21 for storing the PLU number.
1. A name area 212 for storing the names of products used for printing and displaying, a unit price area 213 for storing unit prices, and a cumulative sales amount area 214 for cumulatively storing the sales of the products.

FIG. 4 is a flow chart showing the processing of this embodiment. This flow chart starts when there is an input from the keyboard 2. First, what the input key is is determined. Here, if it is the PLU key, the processing from step 101 onward is executed, if it is the discount key, the processing from step 113 onward is executed, and if it is the batch ratio discount key, the processing from step 119 onward is executed. Further, if it is a sub-total key, the processing from step 124 onward is executed, if it is a closing key, the processing from step 131 onward is executed, and if it is a ten-key, the processing from step 137 onward is executed. If neither of these keys is present, other processing is performed in step 139.

When it is determined that the key is the PLU key in step 100, the subtotal flag is first 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 or not the batch ratio discount flag is set. If the lump rate discount flag is set, it means that the lump rate discount is registered, so in step 104 the rate stored in the lump rate discount rate storage area was entered.
Calculate the registration amount and discount amount from the unit price corresponding to the PLU number. In step 105, which is a means for summing the discount amount, the discount amount is cumulatively stored in the discount cumulative storage area, and in step 106, the registered amount is cumulatively stored in the one-customer total storage area or the like. In step 107, the registered amount is displayed, and in step 108, which is the mark printing control means, the product data such as the product name and unit price and the batch rate discount mark are printed on the receipt, and the process ends. If the collective rate discount flag is not set, the registration is normal registration, and the registered amount is cumulatively stored in the one-customer total storage area or the like in step 109. In step 110, the registered amount is displayed, and in step 111, product data such as the product name and unit price is printed on the receipt, and the process ends.

If it is determined in step 112 that the discount key has been input, then in step 113 it is determined from the batch ratio discount flag 23 whether or not the declaration of batch ratio discount has already been made. This is to prevent double discounting. If the lump rate discount flag 23 is set, the lump rate discount processing has already been performed, so error processing is performed in step 117. If the lump rate discount flag 23 is not set, it is determined in step 114 by the product registration flag 22 whether product registration has been performed before the discount key 18 is input. If the merchandise registration flag 22 is set, merchandise has been registered, so the discount amount that may have been input with the ten keys 13 is stored in the discount cumulative storage area in step 115, and the value is recorded on the receipt in step 116. The discount amount is printed and the process ends. If the product registration flag 22 is not set, error processing is performed in step 117. Error processing is a message indicating an operation error, and the buzzer is turned on. When the Clear key is input, the process returns to the state before the error operation. The operator has to perform the operation again from the state before the operation error occurs.

 Steps 105 and 115 are amount summing means.

When it is determined in step 118 that the batch rate discount key 17 has been input, it is determined in step 119 whether or not product registration has already been performed. If the product registration flag 22 is set, the product has already been registered, so the batch ratio discount key
Perform error handling to invalidate 17 inputs. If the product registration flag 22 is not set, the batch ratio discount flag 23 is set in step 120, and the% key 1 is set in step 121.
Wait for input of 5. Step 1 when the% key 15 is entered
The value input by the ten-key pad 13 at 22 and stored in the numeral storage area 27 is stored in the batch ratio 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 or not by the product registration flag 22. If the merchandise registration flag 22 is not set, the merchandise registration has not been performed yet, and thus the process ends. If the product registration flag 22 is set, the subtotal flag 24 indicating that the subtotal operation has been performed is set in step 125, and the discount total storage area 25 is set in step 126 which is the registration discriminating means and the discount discriminating means. From the value of, it is determined whether the discount was registered for this transaction. If the value of the total discount storage area 25 is 0, there is no discount processing in this transaction, so the process proceeds to step 128. If a numerical value has been stored in the discount total storage area 25, it is the amount printing control means and the discount amount printing control means in step 127. The discount total stored in the discount total storage area 25 is received. Print on. Step 12
The subtotal amount, the tax amount, and the total amount are printed in 8, and the total amount is displayed in step 129, and the process ends.

When it is determined in step 130 that the closing key 20 has been input, in step 131 it is determined by the subtotal flag 24 whether subtotal processing has been performed. If the subtotal flag 24 is not set, the subtotal processing has not yet been performed, and the processing ends. If the subtotal flag 24 is set, in step 132 the value stored in the one-customer total storage area 26 is subtracted from the value input by the numeric keypad 13 and stored in the numeral storage area 27, and the change is calculated. Display the change with 133. In step 134, print the deposit, change, etc.,
In step 135, various flags, total discount storage area 25, total customer storage area 26, collective rate discount rate storage area 28
Is cleared and the process ends.

If it is determined in step 136 that the numeric keypad 13 has been input, the numerical value input in step 137 is displayed and step 1
At 38, the number is stored in the numeral storage area 27, and the process ends.

FIG. 5 is an example of printing a receipt output in this embodiment. (1) is a printing example in the case of a single item discount, and (2) is a printing example in a batch ratio discount. The operation of this embodiment will be described using this printing example.

Then, enter the discount amount of 300 and enter the discount key, and the discount amount of 300 is printed as -300. The following is a discount of 40 yen for punches and a discount of 100 yen for notebooks. By entering the subtotal key, the total discount amount of 440 will be printed. The printing will look like (a). In addition, the subtotal amount of 8520 yen, tax amount of 255 yen, and total amount of 8775 yen will be printed. If the customer paid 9,000 yen, the number would be 9000,
Enter the closing key. The deposit amount 9000 and change 225 are printed.

Next, the batch ratio discount will be described with reference to (2). The operator inputs a collective rate discount key according to the customer bringing a service card or the like, and sets a discount rate. Now, it is assumed that a uniform rate discount of 5% is performed. Enter the batch rate discount key, enter 5, and enter the% key. Then enter the calculator's PLU number 001 from the keyboard. 5000 on receipt and unit price
Circles and a batch percentage discount mark indicating that percentage discounts are being made uniformly are printed. The printing will look like (a). Do the same for punches and notebooks, and enter the subtotal key to print the discount amount of 448. In addition, the subtotal amount of 8512 yen, tax amount of 255 yen, and total amount of 8767 yen will be printed. If the customer paid 9,000 yen, enter 9000 and enter the closing key. Deposit 9000 and change 23
3 is printed.

As described above, according to the present embodiment, it is possible to know the total amount of the discounted or the percentage discounted without complicated calculation. Moreover, since the mark indicating the batch ratio discount is printed together with the product data for the products for which the batch ratio discount has been performed, the customer can easily know that the batch ratio discount has been performed. Such a method that does not print the discount rate for each product is effective for transactions that the customer naturally knows, such as performing a certain percentage discount on all products, that is, when the discount rate is constant. Is.

In the present embodiment, the batch rate discount is calculated by summing the discount amount for each registration of each product, but may be calculated and printed when the subtotal key is input. Furthermore, the discount mark is not limited to this embodiment. In addition, various modifications can be made without departing from the spirit of the present invention.
