Abstract

PURPOSE:To prohibit a discount processing at the time of a misoperation and to reduce the burden of a cashier by setting the ceiling value of the discount amount for the total amount, and prohibiting the discount processing to exceed the ceiling value. CONSTITUTION:After the cashier registers the departments of the total commodities purchased by one customer, and the discount amount is replaced by a replacing key 21 in the case of the customer whose purchase amount is discounted, the cashier operates a discount key 25. Then, the discount ceiling value corresponding to the amount range including the total amount in a single customer counter 33 is read from a discount table 36, and it is compared with the inputted discount amount. When the discount amount is with in the discount ceiling value, the discount processing to subtract the discount amount from the total amount is executed, while, when the discount value exceeds the discount ceiling value, the discount processing is prohibited. Thus, at the time of the misoperation, the discount processing is prohibited, and the burden of the cashier can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic cash register having a discount function.

[Prior Art] In general, electronic cash registers receive sales data such as the number of sales items, sales amount, etc. regarding the product by inputting product data such as code, number of items, and amount of sales items through an input device such as a keyboard. This sales data is registered in the memory by code, for example. In addition, the sales amount of each sales product is totaled by the totalizer, and the amount calculated in the totalizer according to the registration closing operation, that is, the total amount for one word, is displayed and printed, and then the totaler is displayed and printed. Clear. It also has a discount key for inputting the discount amount for the total amount, and when the discount amount is input by operating this discount key, the discount amount is automatically subtracted from the total amount in the totalizer. It becomes.

[Division WJ that the invention seeks to solve] However, in conventional electronic cash registers of this type, there is no upper limit set for the discount amount, so even if there is an operational error of entering a discount amount that exceeds the total amount, the automatic cash register There was a problem where discount processing was performed. If there is an operational error in such a discount process, the registration for that customer must be redone, which is complicated and burdens the cashier.

Therefore, the present invention sets an upper limit on the discount amount for the total amount and prohibits discount processing that exceeds this upper limit amount, so that the discount processing can be performed even if there is an operational error of inputting a discount amount that exceeds the total amount. The present invention aims to provide an electronic cash register that can reduce the burden on the cashier.

[Means for Solving the Problems] The present invention registers the sales data of each sales product input through an input device in a memory, totals the sales amount of each sales product with a totalizer, and performs a registration closing operation. Display the total amount in the totalizer above according to the above.

In an electronic cash register that prints and clears the totalizer, there is a discount table that sets an upper limit discount amount lower than the applicable amount range corresponding to a predetermined total amount range, and a discount amount for the total amount. When the discount key is entered and the discount amount is entered by operating the discount key before the registration close operation, the upper limit discount value is read out from the discount table for the amount range that includes the total amount in the totalizer. an amount reading means; a comparison means for comparing the upper limit discount amount read by the reading means with the discount amount input by operating the discount key; and when the comparison means shows that the discount amount is within the upper limit discount amount. An electronic system characterized by comprising a discount processing control means that performs a discount process to subtract the discount amount from the total amount in the totalizer, and prohibits the discount process when the discount upper limit amount is exceeded. cash register.

[Function] With an electronic cash register that takes such measures, when the sales data of each sales item is input through the input device, it is registered in the memory and the sales amount of each sales item is recorded. Added by a totalizer. In this state,
When the discount amount is entered by operating the discount key, the discount table is searched based on the total amount in the totalizer, and the discount table is searched based on the total amount in the totalizer, and the amount range that is set corresponding to the amount range that contains the total amount is searched. Also, the lower limit discount amount is read out. and,
The read upper limit discount amount and the entered discount amount are compared, and if the discount amount is within the upper limit discount amount, the discount amount is subtracted from the total amount in the totalizer and the discount is processed. If the discount amount exceeds the discount upper limit amount, the discount processing will not be performed. Therefore, in the discount table, the upper limit discount amount is set to be lower than the amount range, so even if a discount amount exceeding the total amount is input, no discount processing will be performed.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an electronic cash register. In the same figure, 1 is the CP as the main body of the control unit.
It has a built-in arithmetic circuit, memory control circuit, etc., executes predetermined arithmetic processing based on various input data, and stores programs etc. for the CPU to control each part via the pass line 2. A RAM 4 having a memory for registering sales data of each sales product, etc. is controlled. In addition, "registration", "payment",

10 boats 18, etc. are connected to the CP via the pass line 2.
Connected to the UI.

As shown in FIG. 2, the keyboard 14 includes a number key 21 for entering the sales amount of each sales product, the deposit amount from one customer, etc., and a number key 21 for entering the department code to which each sales product belongs. In addition to product registration keys such as a department key 22, a subtotal key 23 for commanding display and printout of the subtotal amount, and a deposit/cash total key 24 that functions as a sales registration closing key, there are also keys for entering discount amounts. Various function keys are provided, such as a discount key 25, a multiplication key 26 for instructing multiplication registration, and a clear key 27 for instructing cancellation of an error sound.

As shown in FIG. 3, the RAM 4 includes a departmental totalizer 31 that accumulates the number of sales points and sales amount for each department in which each sales product is classified, a totalizer for each department that accumulates sales by cash settlement, and a discount amount. a transaction totalizer 32 consisting of a discount totalizer, etc., which accumulates the value, a numeric buffer 33 that temporarily stores the numeric data set by the numeric key 21, and stores a registration flag that is set to "1" during sales registration. Flag memory 34, -
In addition to normal memories such as a customer totalizer 35 that calculates the total amount by adding up the sales amounts of products sold to multiple customers, -
A discount table 36 is formed that stores an upper limit discount amount lower than the corresponding amount range corresponding to each arbitrarily set amount range for the total amount M calculated by the word totalizer 35. There is.

In addition, in this example, if the total amount M is less than 1,000 yen, the upper limit of discount amount is 0 yen, and if the total amount M is less than 1,000 yen,
If the amount is less than 00 yen, the upper limit of discount is 500 yen, and 500 yen
If the amount is 0 yen or more and less than 10,000 yen, the maximum discount amount will be 100 yen.
0 yen, and if the amount is 10,000 yen or more, the maximum discount amount will be 20 yen.
00 yen, the discount table 36 is set according to the "setting" mode.
Set in advance.

After the CPU performs predetermined processing in response to power-on, it waits for key data to be input from the keyboard 14. Then, when the key data is input, the business mode selected by the control key 5 is determined,
Execute key processing corresponding to the applicable business mode.

Here, with the "registration" mode selected by the control key 5, press the department key 22 from the keyboard 14.
When the key data is input, the department key processing shown in FIG. 4 is executed. First, in step (ST) 1, it is confirmed that the numeric data is stored in the numeric buffer 33, and then the department code corresponding to the key data in the departmental totalizer 31 is registered in the totalizer. In other words, the number data is set as the sales amount, and if the number of points has been entered in advance by multiplication registration, that number is set as the number of sales points.
If it is not entered, the number of sales points is set to "1" and added to the number of sales points and sales amount of the corresponding department totalizer. Then,
In ST2, the above sales amount is added to the per-customer totalizer 35. Further, the corresponding department code and sales amount are displayed on the display section 12, printed out on the receipt by the printer 9, and the registration flag in the flag memory 34 is set to '1'', and the process ends.

Also, with the "registration" mode selected,
When the key data of the deposit/account key 24 is input from the keyboard 14, the deposit/account key process shown in FIG. 5 is executed. First, in ST3, it is confirmed that the registration flag in the flag memory 34 is set to "1°," that is, that a product purchased by one customer is being registered, and then, in ST4, a number is set in the number buffer 33. Check whether the data is stored or not.If it is stored, this customer paid more cash than the total amount, so the total in the customer totalizer 35 is calculated from the stored number data, that is, the deposited amount. A change calculation is performed to subtract the amount, and the calculated change amount is displayed on the display unit 12.The total amount, deposited amount, and change amount are also printed on the receipt. If the number data does not exist, the customer paid an amount equal to the total amount in cash, so the total amount in the totalizer 35 is displayed on the display section 12 and printed on the receipt.

Thereafter, a receipt is issued as Sr5, and the drawer 7 is opened. Also, the total amount in the -joy totalizer 35 is added to the current total in the transaction-specific totalizer 32, and this -
Clear the word totalizer 35.

After that, the registration flag in the flag memory 34 is set to “
0” and exit.

Also, with the "registration" mode selected,
When the key data of the discount key 25 is input from the keyboard 14, the discount key process shown in FIG. 6 is executed. First of all,
The registering flag in the flag memory 34 as Sr6 is “1”
After confirming that the value is set to , and that the number data is stored in the number buffer 33, the amount range that includes the total amount M in the customer totalizer 35 from the discount table 36 as Sr7 , and read out the upper limit discount amount corresponding to this range. Specifically, first, the total amount M is 10
If it is less than 1000 yen, the upper limit discount amount is set to 0 yen. If the amount is 1,000 yen or more, it is then determined whether it is less than 5,000 yen.

If the price is less than 5,000 yen, the upper limit of the discount is set to 500 yen. If the amount is 5,000 yen or more, then 10,000 yen
Determine whether it is less than yen.

If the amount is less than 10,000 yen, the maximum discount amount will be 100 yen.
0 yen, and in the case of 10,000 yen or more, the upper limit of discount amount is 2
000 yen.

Next, the discount upper limit amount read as Sr1 is compared with the number data stored in the number buffer 33, that is, the discount amount. If the discount amount exceeds the discount upper limit amount, subsequent processing is prohibited as an error, and the buzzer 16 is sounded to alert the cashier. Incidentally, in response to input of the clear key 27, the error state is canceled and the buzzer 16 stops.

On the other hand, if the discount amount is less than the discount upper limit amount in Sr1, discount processing is executed. That is, the discount amount in the numeric buffer 33 is subtracted from the total amount in the negative totalizer 35. Further, this discount amount is added to the discount totalizer in the transaction-by-transaction totalizer 32. Further, the discount amount is displayed on the display unit 12 and printed on the receipt, and the process ends.

In a store that employs the electronic cash register of this embodiment configured in this way, the cashier registers the departments of all the products purchased by one customer, and then gives a discount to the customer's total amount. Decide whether to proceed or not. and,
In the case of a customer who does not give a discount, the registration is immediately closed by operating the deposit/account key 24, but in the case of a customer who gives a discount, the discount amount is entered using the number key 21. After that, operate the discount key 25. Then, the upper limit discount amount corresponding to the amount range containing the total amount in the customer totalizer 33 is read from the discount table 36 and compared with the input discount amount. If the discount amount is within the discount upper limit amount, a discount process is performed in which the discount amount is subtracted from the total price, but if the discount amount exceeds the discount upper limit amount, the discount process is prohibited.

Therefore, discounts are not allowed for customers whose total amount is less than 1000 yen. Total amount is 1000 yen or more 5000 yen
Discounts of up to 500 yen are allowed for customers who spend less than 500 yen, but discounts beyond that amount are prohibited. Similarly, for customers whose total amount is 5,000 yen or more and less than 10,000 yen, 100 yen will be charged.
Discounts up to 0 yen are allowed, but discounts beyond that are prohibited, and customers with a total amount of 10,000 yen or more will receive a 200 yen discount.
Discounts up to 0 yen are allowed, but no more than that.

As described above, according to this embodiment, by setting an amount lower than the corresponding total amount range as the discount upper limit amount, an erroneous operation in which a discount amount exceeding the total amount is input in a discount operation is prevented. Even if the cashier receives the discount, the discount process is stopped, and in this case, the cashier only has to re-enter the correct discount amount, eliminating the need to re-register the customer as in the past. Therefore, the burden on the cashier can be reduced.

In addition, a maximum discount amount is set for the total amount, so
It also prevents fraud, such as a cashier giving an unnecessary discount to a customer he knows.

Note that the present invention is not limited to the above embodiments,
Of course, various modifications can be made to the set value of the monetary amount range, the set value of the upper limit discount amount, etc. in the discount table 36.

[Effects of the Invention] As described in detail above, according to the present invention, by setting an upper limit on the discount amount for the total amount and prohibiting discount processing that exceeds this upper limit amount, it is possible to reduce the amount of discount that exceeds the total amount. To provide an electronic cash register that can prohibit discount processing if there is an input operation error and can reduce the burden on a cashier.
