Description

Description: TECHNICAL FIELD The present invention relates to an electronic cash register capable of automatically discounting a fractional amount according to a certain rule when the total amount is fractional.

[Prior Art] In a general store, when a customer purchases a plurality of products, if the total amount of sales of each product has a fractional value, the fractional value is rounded down to substantially correspond to the fractional value. There are many cases where you can get a discount. For example, when the total amount is 10019 yen, the fraction 19 yen is discounted. Then, 10000 yen after the rounding down is processed as the actual cash sales amount.

In the electronic cash register capable of executing such a discount process, a numeric key for entering a sales amount on a keyboard, a department key for entering a department code of a product to be sold, and a product sold to one customer. A discount key is arranged in addition to a normal sales registration key such as a subtotal key for calculating the subtotal amount of money and a total key as a closing key for similarly calculating the total amount.

Then, the cashier sequentially enters the sales amount and department code of each product for sale with the numeric key and the department key, and when the input operation for all products is completed, the subtotal key (total amount) is entered with the subtotal key. When the above-mentioned fractional amount is generated in the total amount when it is displayed on the display unit, the fractional amount is entered with the numeric key and then the discount key is operated. Then, the fractional amount is subtracted from the total amount. And
When the total key is operated, the rounded down amount is displayed on the display unit, which is a good rounded down amount after subtracting the rounded amount.
Then, the customer pays the rounded-down amount displayed on the display.

[Problems to be Solved by the Invention] However, there is the following problem that still needs to be improved in the electronic cash register in which the fractional amount discount processing is executed by the key operation as described above. It was That is, when a fraction is generated in the total amount, the cashier needs to perform the discount operation with the fraction key and the discount key. Therefore, the burden on the cashier is increased and the work efficiency of the entire sales registration work is reduced.

Further, if the range of the fraction to be discounted is not determined, it is often left to the discretion of the cashier. For example, as described above, when the total amount of money is 10019 yen, it may be possible to discount the fractional yen of 9 yen depending on the cashier and the case of discounting the fractional value of 19 yen. Therefore, there is a concern that it may be unfair to the customers.

The object of the present invention is to reduce the cashier's burden by automatically discounting the fraction of the total amount within a predetermined range when the tightening key is pressed, thereby improving the work efficiency of sales registration work and providing customers with it. The aim is to provide electronic cash registers that can be sold fairly.

Another object of the present invention is to provide an electronic cash register capable of executing / stopping the automatic discount function as needed in addition to the above object and further improving operability.

[Means for Solving Problems] In the electronic cash register of the present invention, as shown in FIG. 1, the total amount 2 calculated by the closing key operation 1 is added to the total amount dividing unit 3 from the top (n + 1). It is divided into a fractional cutoff amount 4 in which each number of digits below the digit is 0 and a fractional amount of money 5 in which each number in the upper n digits is 0, and in response to the closing key operation, the discount registration means 6 causes the fractional amount. The amount of money 5 is accumulated as a discounted amount in the discount summing device 7, the discounted amount printing means 8 prints out the discounted amount on the receipt 9, and the cash sales registration means 10 makes a fraction in response to the closing key operation. Rounded down amount 4
Is accumulated in the cash sales total unit 11 as the cash sales amount.

In another invention, in addition to the above invention, an automatic discount key 12 is provided so that the total amount dividing means 3 can be selectively executed.

[Operation] In the electronic cash register configured as described above, if the total amount of money has a fraction when the closing key operation is performed, the total amount of money is 0 (n + 1) or less digits from the top. Is rounded down and the upper n digits are rounded down to 0. Then, the fractional amount of money is accumulated as a discount amount to the discount totalizer and is printed out on a receipt, and the fractional amount of money is accumulated as a cash sales amount to the cash sales totalizer. Therefore, the discount of the fractional amount is automatically executed.

In addition to the above operation, the operation of another invention is to perform the above-mentioned automatic discount processing by operating the automatic discount key.
Stop control is performed.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view showing an electronic cash register according to the embodiment. As shown in the figure, a keyboard 22 as an input device is provided on the front surface of the housing 21, and the department code of the product to be sold is provided above the housing 21. A display unit 23 for electronically displaying the sales amount, the total amount, etc. is provided, and a receipt issuing port 24 and a cash drawer 25 for storing cash are provided in the middle and lower portions, respectively. Further, the display unit is provided on the upper surface of the housing 21.
A customer display unit 26 having the same configuration as that of 23 is attached.

On the keyboard 22, as shown in FIG. 3, for calculating the total amount of money, a numeric key 27 for inputting the sales amount of the product, a department key 28 for indicating the classification of the product, a subtotal key 29, and a total amount of money. In addition to a sales registration key such as a cash (total cash) key 30 as a closing key, an automatic discount key 31 for instructing an automatic discount is provided. Further, a control key 32 that is operated by a key is provided.

The control key 32 is a control switch for performing on / off control of the power supply and for instructing the central processing unit to execute various tasks such as [registration] and [settlement]. [Registration] means to store the department code, sales price, sales quantity, etc. of the sold product in the storage unit, calculate the total price, etc., and print the result on the receipt and internal recording paper (journal). It is business. Further, “payment” is a job for printing out the total sales registered in the storage unit at the end of the day's job.

FIG. 4 is a block diagram of an electronic cash register. The CPU (central processing unit) 33 has a built-in arithmetic circuit and the like,
Performs various types of arithmetic processing based on the input information from the keyboard 22, address bus 34, data bus 35, control lines
The ROM 37, which stores fixed data such as the programs for each business, and the RAM 38, which stores sales data such as the sales amount of each product key-inputted, are operated via 36. Also,
A control key input circuit 39 to which a command signal from the control key 32 is input, a keyboard input circuit 40 to which a key signal from the keyboard 22 is input, a display control circuit 41 for sending a display signal to the display units 23 and 26, a receipt and Printer control circuit of dot printer 42 that prints out to the journal
43 are connected to the CPU 33 via the data bus 35 and the control line 36, respectively.

Further, in the RAM 38, as shown in FIG. 5, the sales amount and the number of sales points of each sales item input by the combination key operation of the numeral key 27 and the department key 28 of the keyboard 22 are classified by department code. Registration file R1 for each department to be counted, Numeric key
A numerical register Huffa R2 for temporarily storing the numerical data registered at 27, a totalizer R3 for calculating the total amount of sales of each product sold to one customer, and the like are formed. Furthermore, in this RAM38, a cash sales total device R5 for accumulating the actual cash sales amount after the discount, a discount total device R5 for accumulating the discount amount, and an automatic indicating that the automatic discount processing is being executed. A flag area R6 for storing a discount flag and a flag area R7 for storing a registration flag indicating that the registration process for one customer is being performed are formed.

Then, the CPU 33 is programmed so as to execute the main routine of FIG. 6 when the power is turned on and the predetermined initial processing is completed. That is, when the main routine is started, it is confirmed that the control key 32 is set to the [register] work mode. Then, when the numeric keypad 27 is keyed in at P1, the numeric data keyed in is stored in the numeric buffer R2 of the RAM 38. Also, P2
When the department key 28 is keyed in, the registration flag in the flag area R7 of the RAM 38 is checked, and if it is not yet set to 1, it is determined that the registration of the first product for this customer has started, Set the registering flag to 1. Then, the numerical data stored in the number buffer R2 is added to the sales amount of the corresponding department code of the department registration file R1 of the RAM 38 as the sales amount of the product, and the sales points are updated. At the same time, the sales amount is added to the totalizer R3. Further, the department code and the sales amount are printed out on the receipt by the dot printer 42.

If the automatic discount key 32 is pressed on P3,
If there is a fraction in the total amount of money for this customer, it is determined that the fraction will be automatically discounted, and after confirming that the registering flag in the flag area R7 is set to 1, the flag area
Set the automatic discount flag of R6 to 1.

Further, when the current total key 30 is keyed in as a closing key operation at P4, the setting state of the automatic discount flag in the flag area R6 of the RAM 38 is checked at P5. And the automatic discount flag is 0
If it is still canceled, it is judged that this customer does not need to be automatically discounted even if the total amount is rounded. Then, the normal cash registration process after P6 is performed. That is, the total amount of the totalizer R3 is displayed on the display units 23 and 26 and printed on the receipt. Then, the receipt is discharged from the receipt issuing port 24. Next, add the total amount to the total cash sales amount of cash sales totalizer R4,
Clear the totalizer R3. Then, the drawer 25 is opened, and the registering flag in the flag area R7 is cleared to 0 to 1
The sales registration process for one customer ends.

On the other hand, if the automatic discount flag is set to 1 in P5, if there is a fraction in the total price for this customer, it is determined that the fraction will be automatically discounted, and the automatic discount processing after P7. Do. First, print the total amount of totalizer R3 on the receipt on P7.

After that, the n-digit number from the top of the total amount is set to 0 (n +
1) A fractional amount consisting only of digits or less is printed out as a discount amount on a receipt and added to the total discount amount of the discount totalizer R5. Next, the number from the uppermost (n + 1) digits of the totalizer R3 is set to 0, and the number from 0 to n digits is set to 0, and the rounded down amount is formed. Displayed as cash sales amount 2
Displayed on 3,26 and printed out on receipt. Further, this cash sales amount is added to the total cash sales amount of the cash sales totalizer R4. Then, the drawer 25 is opened, the flags in the flag areas R6 and R7 are cleared to 0, and the sales registration process for one customer is completed.

In the electronic cash register configured as described above, for example, when n = 3 is set, when a fraction occurs in the total amount, the fractional amount of money from the fourth digit from the top is discounted.

In this way, in the electronic cash register set to n = 3, the product of department code 1 for 5000 yen and the product of department code 2 for 5019 yen (total price 10019 yen) for one customer
7 and 8 show the print format on the receipt when the product is sold. That is, if the automatic discount key 31 is not entered between the first input of the department key 27 indicating the start of registration and the input of the current total key 30 indicating the end of registration, as shown in FIG. If you key in 30,
As the total amount, 10019 yen, which is not processed by fractional discounting, is printed out.

On the other hand, if the automatic discount key 31 is keyed in during the registration processing period, when the current total key 30 is keyed in, as shown in FIG. 8, the total amount before discount (10019 yen) and the fractional value The discount amount (-19 yen) and cash sales amount (10000 yen) are printed out in sequence.

In this way, by keying in the automatic discount key 31, the cashier only needs to key in the current total key 30, and if a fractional amount occurs in the total amount, this fractional amount will be automatically discounted. It Therefore, the discount operation is very easy and the burden on the cashier can be greatly reduced.
The work efficiency of the entire sales registration work can be greatly improved.

Further, the maximum discount rate of the discounted fractional amount of the total amount is limited to a fixed value by the set value of n. For example, in this embodiment, since n = 3, the maximum fractional amount of money is 1%. In this way, since the automatic discounting process is performed based on a certain rule, the discount is fairly given to all customers.

Further, it is not necessary to operate the automatic discount key 31 in a period or department in which discounting is not required. In this way, it is possible to select whether or not to execute the fractional subtraction process as needed, and therefore, it is possible to make the electronic cash register very easy for the cashier or the person in charge of the store to use.

The present invention is not limited to the above embodiment. In the embodiment, the keyboard 22 has an automatic discount key 31
We made it possible to choose to execute automatic discounting of fractional amount,
The automatic discount key 31 may be removed. In this case, the fractional price subtraction process is executed for all the total amounts. That is, at P4 in the main routine of FIG.
When is input by key, unconditionally executes the fractional subtraction process after P7.

Also, the set value of n that regulates the maximum discount rate may be changeable.

[Effects of the Invention] As described above, according to the present invention, when the tightening key is pressed, the fraction of the total amount is automatically reduced within a predetermined range. Therefore, the burden on the cashier can be reduced, the work efficiency of the sales registration work can be improved, and the sales can be done fairly to the customers.

Further, since the automatic discount function can be executed / stopped as necessary, the operability can be further improved.
