Abstract

PURPOSE:To simplify a small change management by constituting a commodity sales data processor so that a commodity ticket can be issued, when a fraction money amount of change generated by a keeping/adding-up operation exceeds a prescribed ticket issue reference money amount. CONSTITUTION:When change is calculated by a keeping/adding-up operation by a CPU 1 in a state that a fraction totaling card is installed in a card data input/output part 17, a fraction money amount being less than a prescribed unit to the change is calculated automatically, and its fraction money amount is brought to addition processing to a fraction total money amount of the frac tion totaling card. In this state, when the fraction total money amount totaled to the fraction totaling card exceeds the reference money amount, a commodity ticket of the money amount obtained by adding a prescribed privilege money amount to its reference money amount can be issued. Accordingly, it becomes unnecessary to pay the fraction money amount generated as change in cash as it is, and also, by giving a privilege of a privilege money amount portion to a customer at the time when its customer repeats shopping in a store, it is possible to give a strong impression of the privilege on the customer.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to product sales data processing devices such as electronic cash registers and POS (point of sale) systems in which multiple cash registers are centrally managed by a controller. In particular, the present invention relates to a device that can efficiently process fractions of change.

[Prior Art] For example, in mass retailers such as supermarkets, various products with fractions of 100 yen or 1 yen and 11i are sold, so the customer's total price also includes 100 yen.
Payments are often made in yen or fractions of 1 yen, but most customers do not have small change or find it troublesome to collect cash for the total amount, so they pay in larger units than fractions. , I try to take the change from the receiver. j7
Therefore, change was likely to be a fraction of 100 yen or 1 yen.

[Problem to be solved by the invention] However, in the past, the fractional amount of change was paid to the customer as change, so the customer had to prepare a large amount of small change as cash for change, which was troublesome to manage. there were. In addition, there was no benefit for the customers as they only had to spend 5 yen or 1 yen more in change.

SUMMARY OF THE INVENTION Therefore, the present invention provides a product sales data processing device that can accumulate fractional amounts of change in the customer's waiting room and simplify coin management by eliminating the need for giving and receiving fractional amounts as change. That is.

[Means for Solving the Problems] The first invention of the present application includes a card data input/output unit that inputs and outputs data to and from a fractional accumulating card that stores at least a customer identification code and a fractional cumulative amount, and this card. When the deposit/closing operation is performed with the @dispersion totalization card installed in the data input/output unit, there is an automatic fractional amount calculation means that automatically calculates the fractional amount less than a predetermined fractional unit for the change, and a fraction accumulating processing means for adding the fractional amount to the fractional cumulative amount of the fractional cumulative amount of the fractional accumulating card attached to the card data input/output unit, and displaying on a display the change payment amount calculated by subtracting the fractional amount from the change. This product sales data processing equipment is equipped with change payment amount display control means.

Further, it is preferable to include a gift certificate issuance control means for issuing a gift certificate for an amount obtained by adding a predetermined benefit amount to the reference amount when the fractional cumulative amount added by the fractional cumulative amount is equal to or more than the standard amount.

Note that the fractional amount automatic calculation means is to set fractional unit data on the fractional accumulating card and automatically calculate fractional amounts less than the fractional unit set on the fractional accumulating card attached to the card data input/output section. is possible.

In addition, the fractional unit data is set on the fractional accumulating card, and a fractional unit input key is provided, and when the fractional unit data is input using this fractional unit input key, the fractional accumulating card attached to the card data input/output section is It is also possible to automatically calculate the fractional amount using the key-input fractional unit data preferentially than the fractional unit data.

The second invention of the present application includes a customer table that stores fractional cumulative amounts corresponding to each identification code of a customer, an input means for the identification code, and a deposit closing operation with the identification code input by the input means. Fractional amount automatic calculation means that automatically calculates a fractional amount less than a predetermined fractional unit for change when a fractional amount is calculated by the calculation means, and a fractional amount in a customer table corresponding to the identification code inputted by the inputting means. This product sales data processing device includes a fractional summation processing means for adding to the cumulative amount, and a change payment amount display control means for displaying on a display the change payment amount calculated by subtracting the fractional amount from the change.

Further, it is preferable to include gift certificate issuing fA control means for issuing a gift certificate for an amount obtained by adding a predetermined award amount to the reference amount when the fractional cumulative amount added by the fractional cumulative amount is equal to or more than the standard amount.

Note that the automatic fractional amount calculation means sets fraction unit data corresponding to each identification code in the customer table, and automatically calculates fractional amounts less than the fractional unit in the customer table corresponding to the identification code input by the input means. It is conceivable to calculate it.

In addition, data in fractional units is set in the customer table corresponding to each identification code, and a key for inputting fractional units is provided. When fractional unit data is input using this key, the identification code input by the input means It is also possible to automatically calculate the fractional amount by giving priority to the fractional unit data of the customer table corresponding to the code by using the key-input fractional number I1'L data.

A third invention of the present application is that in the first invention, a fractional amount key is provided in place of the fractional amount automatic calculation means, and a fractional amount key is provided in place of the fractional amount automatic calculation means, and when a fractional amount accumulating card is attached to the card data input/output section and a deposit and closing operation is performed. When a fractional amount is entered using the fractional amount key, the fractional amount is added to the fractional cumulative amount of the fractional cumulative amount.

A fourth invention of the present application is that in the second invention, a fractional amount key is provided in place of the fractional amount automatic calculation means, and the fractional amount key is used to calculate the fractional amount when the identification code is input by the input means and the deposit closing operation is performed. Once the amount is keyed in,
The fractional amount is added to the cumulative fractional amount in the customer table corresponding to the identification code input by the input means.

[Function] In the first invention, when change is calculated by the deposit and tightening operation with the fractional accumulating card attached to the card data input/output unit, a predetermined amount (fractional amount less than 1st place) for this change is calculated. The fractional amount is automatically calculated and added to the fractional cumulative amount on the fractional cumulative amount.When the fractional cumulative amount accumulated on this fractional cumulative amount exceeds the standard amount, a predetermined amount is added to the standard amount. It is possible to issue a gift certificate with the amount added to the reward amount.Therefore, there is no need to pay the fractional amount generated as change in cash, and if the customer repeats shopping at the store, the customer can receive the amount of the reward amount. This will give the customer a special benefit, giving the customer a strong impression of the special benefit.

In the second invention, when change is calculated by a deposit and closing operation with the customer's identification code input, a fractional amount less than a predetermined unit for this change is automatically calculated, and the fractional amount is input into the customer table. The fractional amount is added to the total amount corresponding to the identification code. When the fractional amount accumulated in this customer table exceeds the standard amount, it is possible to issue a gift certificate with an amount equal to the sacrificed amount plus a predetermined benefit amount. Therefore, it is no longer necessary to pay the fractional amount that is generated as change in cash, and when the customer repeatedly shops at the store, the customer is given a benefit equal to the benefit amount, giving the customer a strong impression of the benefit. Become.

The fraction is added to the cumulative total amount in the customer table corresponding to . In this case as well, there is no need to pay the fractional amount generated as change in cash, and if the customer repeats shopping at the store, the customer will receive a benefit equal to the benefit amount.
This will give customers a strong impression of the benefits.

[Example] Hereinafter, an example in which the present invention is applied to a single electronic cash register will be described with reference to the drawings. In the first embodiment, it is assumed that a magnetic card is used as the card for adding up fractions. This fraction accumulating card has a magnetic stripe section on one side and a printing surface on the other side. As shown in FIG. 4, the magnetic stripe section includes setting areas 41 and 42 for the customer code and store code as the identification code of each customer, as well as a storage area 43 and a storage area 43 for data indicating fractional units of change. A storage area 44 is provided for each fractional cumulative amount.

FIG. 1 is a block diagram of an electronic cash register, in which a CPU (central processing unit) 1 serves as the control unit main body.
has a built-in arithmetic circuit, a memory control circuit, etc., and executes various arithmetic processing based on input data, and also connects to the storage section of ROM 3 and RAM 4, clock circuit 5, I10 board 6, and keyboard circuit via path line 2. 7. Controls the display control circuit 8, I10 boat 9, and card reader/writer control circuit 10, respectively.

The bipod ROM 3 stores program data and the like necessary for the CPU to control each section. '' The two-legged RAM 4 includes a memory for registering product sales data that has been registered for sale through a product registration operation.

The clock circuit 5 measures the current fabric weight and time. A mode switch 11 for selecting and specifying various business modes such as "registration,""accounting," and "setting" is connected to the I10 boat 6, and a selection designation signal from this mode switch 11 is input. The keyboard circuit 7 is for receiving key input signals from the keyboard 12. The display control circuit 8 is connected to a display 13 for electronically displaying the total sales amount of products, the amount of change, etc., and drives and controls the display 13 to display characters, etc. corresponding to the display data. . I1 above
The 0 boat 9 includes a receipt/journal (R/J) printer 14 that prints on receipts and journals (internal recording paper), and a printer that prints on the printing surface of the card for cumulative fractions attached to a card reader/writer 17 (described later). A printer drive circuit 16 is connected to drive each of the card printers 15 and 15, and a drive signal for each printer 14 and 15 is output to this drive circuit 16.

The card reader/writer control circuit 10 connects a card reader/writer 17 that reads and writes data to the magnetic recording surface of a magnetic card, inputs card data read by the card reader/writer 17, and receives data from the CPUI. This outputs the following. That is, the card reader/writer 17 and the card reader/writer control circuit 10 constitute a card data input/output section.

As shown in FIG. 2, the keyboard 12 includes number keys 21 for inputting the sales amount of sales products, deposit amount from customers, etc., and a plurality of preset department codes for classifying each product. In addition to product registration keys such as the department key 22 and the deposit/cash key 23 that instructs customers to close their deposits by paying in cash, there are also various keys such as a clear key 24, a ticketing key 25, a multiplication key 26, and a fractional 11t key 27. Function keys are provided.

In addition to the above-mentioned product registration memory, the RAM 4 includes:
As shown in FIG. 3, there is a total amount memory 31 that stores the total sales amount for one transaction of products registered for sale through a product registration operation, a change memory 32 that stores the amount of change, and a fractional amount that stores the fractional amount of change. Memory 33, fraction of change il1
a fractional unit memory 34 for storing the fractional amount, a fractional cumulative memory 35 for storing the cumulative fractional amount, an issued amount memory 36 for storing the standard amount for gift certificate issuance, a privilege amount memory 37 for storing a certain award amount, and the card reader. A flag memory 38 for a card flag CF that is set (1) when a fraction accumulation card is inserted into the writer 17, a flag memory 39 for a fraction unit flag FF that is set by a key input operation of the fraction unit key 27, etc. It is formed. Note that the standard ticketing amount in the ticketing amount memory 36 and the award amount in the award amount memory 37 can be arbitrarily set by inputting a predetermined key on the keyboard 12 while the "setting" mode is selected and designated by the mode switch 11. It has become something that

Therefore, the CPUI is set to "
The program is configured to execute the card processing shown in FIG. 5 at predetermined intervals in a state where the "Registration" mode is selected and designated. In other words, CPUI is ST (step)
1, it is periodically determined via the card reader/writer control circuit 10 whether or not a magnetic card is attached to the card reader/writer 17. If it is determined that the card is not installed, the state of the card flag CF in the flag memory 38 is checked in ST2. Here, if the card flag CF has been reset, the card-uninstalled state continues, so this process is ended.

If the card flag CF was set in ST2, the magnetic card attached to the card reader/writer 17 has been removed, so the card flag CF is reset (0).
) and end this process.

On the other hand, if STI determines that the card is inserted, ST3
The state of the card flag CF in the flag memory 38 is checked. Here, if the card flag CF is set, it means that the card mounting state is continued, and this process ends.

If the card flag CF has been reset in ST3, the card reader/writer 17 has been equipped with a magnetic force and -, so the card flag CF is set (1) and the magnetic card read by the card reader/writer 17. import card data. When it is confirmed by the customer code and store code in the card data that the magnetic card is a card for fractional summation, the fractional amount cumulative data in the card data is stored in the fractional summation memory 35. Also,
If the fractional unit memory FF of the flag memory 39 has been reset, the fractional unit data in the same card data is
A number of small unit memory 34 is stored.

This completes the process.

In addition, when the above-mentioned CPUI selects and specifies the "registration" mode by the mode switch 11, the keyboard 12
The program is configured to execute the commodity transaction process shown in FIG. 6 by inputting a predetermined key. That is,
When the CPU inputs a key signal from the department key 22 as an STI via the keyboard circuit 7, it recognizes that a department registration operation for a sales product has been performed, and registers the product sales data in the product registration memory. Further, the sales amount of the registered product is added to the total amount memory 31. moreover,
The department code and sales amount of the registered product are displayed on the display 13.
At the same time, the R/J printer 14 is driven to print on receipts and journals.

On the other hand, the department registration operation for sales products was not performed in ST1,
When the key signal of the fractional unit key 27 is input as ST2, the state of the fractional unit flag FF in the flag memory 39 is checked first. If the fractional unit flag FF has been reset, it is set to "1" and then the digit data set by the numeric key 21 is stored in the fractional unit memory 34.

On the other hand, if the fractional unit flag FF has been set, it is reset to "0".

Department registration of sales products is performed at STI, followed by STI.
When the deposit/cash total key 23 is inputted at T3 to perform a cash payment operation, change calculation is executed. Here, first, it is determined whether or not a number was entered using the numeric key 21 before the input of the P1/current total key 23 [α].

If the number has been entered, the number data is used as the deposit amount and the total amount memory 31
Calculate the change amount by subtracting the total amount. If no number has been entered, the total amount in the total amount memory 31 is used as the deposited amount and the amount of change is calculated in the same manner. The calculated amount of change is stored in the change memory 32.

Next, it is determined whether the amount of change in the change memory 32 is greater than 01 yen. If it is less than [0] yen, there will be no fractional amount in the change, so a normal closing process using cash payment is executed. Furthermore, even if the amount of change is greater than 0 yen, if the card flag CF is not set, the change accumulation card is not installed in the card reader/writer 17, so the closing process using normal cash payment is still executed. .

If the amount of change is larger than [0] yen and the card flag CF is set, the amount of change in the change memory 32 is divided by the fraction unit in the fraction unit memory 34 and the remainder is calculated to obtain the above fraction. The fractional amount of change that is less than the unit is automatically calculated (fractional amount automatic calculation means), and the calculated fractional amount is stored in the fractional amount memory 33. Next, the amount of change paid to the customer is calculated by subtracting the #Ia loss amount in the fractional amount memory 33 from the above change amount, and the calculated amount of change paid is stored again in the change memory 32 and displayed on the display 13. (change payment amount display control means). Also,
A new cumulative fractional amount is calculated by adding the fractional amount in the fractional cumulative amount memory 33 to the fractional cumulative amount in the fractional cumulative amount memory 35, and the calculated fractional cumulative amount is stored again in the fractional cumulative amount memory 35.

Thereafter, the R/J printer 14 is driven to display the total amount in the total amount memory 31, the deposited amount, the change payment amount in the change memory 32, the fractional amount in the fractional amount memory 33, and the receipt and journal. Each fractional cumulative amount in the fractional cumulative amount memory 35 is printed, and a receipt 70 as shown in FIG. 7, for example, is issued. Further, the fractional cumulative amount data in the fractional cumulative amount memory 35 is outputted to the card reader/writer 17 via the card reader/writer control circuit 10, and the contents of the storage area 44 of the fractional cumulative card installed in the card reader/writer 17 are output. Rewrite (fraction accumulation processing means). Furthermore, the card printer 15 is driven to print the current date a1 read from the clock circuit 5, the above fractional amount, and the above fractional cumulative amount C on the printing surface 80 of the card for accumulating fractions A, as shown in FIG. Print.

Thereafter, the fractional unit flag FF is reset and the process is ended.

Furthermore, when the CPU 1 selects and specifies the "registration" mode with the mode switch 11, the keyboard 1
The program is configured so that when the ticket issue key 25 of No. 2 is inputted, the ticket issue key process shown in FIG. 9 is executed.

That is, when the CPU starts ticket issuing key processing, it confirms that the card flag CF is set, that is, that the card for fractional accumulation is attached to the card reader/writer 17, and then calculates the fractional accumulation in the fractional accumulation memory 35. The amount is compared with the ticket issuing standard amount in the ticket issuing amount memory 36. Then, the cumulative total amount is issued! ! Since it is possible to issue a gift certificate if the amount is equal to or higher than the standard amount, the R/J printer 14 is driven to generate a receipt in a preset format that corresponds to the above-mentioned issuance standard amount plus the benefit amount in the benefit amount memory 37. A gift certificate 100 as shown in FIG. 10 is issued (gift certificate issuance control means).

Next, a new cumulative fractional amount is calculated by subtracting the ticket issuing standard amount from the cumulative fractional amount, and the calculated cumulative fractional amount is stored again in the cumulative fractional amount memory 35. After that, the card printer 15 is driven to print an i8
As shown by the percentage mark in the figure (print the current date a read from the clock circuit 5 and the fractional cumulative amount C, respectively,
This process ends.

In this embodiment configured as described above, the peripheral side issues a fraction accumulating card (magnetic card) to the customer in advance. A customer code and store code set for each successful customer are set in the magnetic stripe section of this fractional accumulating card. Further, the storage area 43 of this magnetic stripe section stores fraction unit data requested by the customer, and the storage area 44 stores an initial value "0". Here, the fractional unit data is, for example, "YUO" for a customer who makes a fractional amount of less than 10 yen in a fishing match, and "50" for a customer who makes a fractional amount of less than 50 yen.

Further, the peripheral party arbitrarily sets the ticketing standard amount and the benefit amount through a setting operation based on the gift certificate issuance conditions. For example, if a gift certificate worth 500 yen is to be issued, and 20 yen of the gift certificate is to be given to a customer as a benefit, the standard ticket issuance amount is 480 yen and the benefit amount is 20 yen.

Thus, when the cashier checks out a customer who has a card for cumulative fractions, the cashier attaches the card for cumulative fractions submitted by the customer to the card reader/writer 17 at the latest before performing the deposit and closing operation.

Then, the card data of the fractional accumulation card is read, and the fractional cumulative amount in the storage area 44 is stored in the fractional cumulative amount memory 35, and the fractional unit in the storage area 43 is stored in the fractional unit memory 34. However, if a fractional unit is keyed in using the number key 21 and the fractional unit key 27 before the tightening operation, the keyed-in fractional unit is used preferentially over the middle fractional unit of the card.

Then, after registering all the purchased products of the customer and receiving payment from the customer, the cashier inputs the deposit amount and inputs the deposit/cash total key 23. Then, the amount of change will be automatically calculated.

If the change amount is greater than [0] yen, the fractional amount less than the above fractional unit of the change amount and the change payment amount excluding the above fractional amount from the change amount are automatically calculated, and the change payment amount is is displayed on the display 413.

Further, the calculated fractional amount is added to the cumulative fractional amount in the fractional amount memory 35, and this new cumulative fractional amount is written to the customer's fractional cumulative amount. Furthermore, the current date, the current calculated fractional amount, and the new fractional cumulative amount are printed on the printing surface 80 of the customer's fractional cumulative amount.

In addition, the total amount, river charge amount, change payment amount, and
The fractional amount and the cumulative fractional amount are printed and issued.

Therefore, the cashier collects the amount of change displayed on the display and hands it to the customer along with the receipt.

Further, if the customer does not request the issuance of a gift certificate, the fractional accumulating card is removed from the card reader/writer 17 and returned to the customer. With this, the accounting work for one customer is completed.

On the other hand, if the customer who has made the transaction requests the issuance of a gift certificate, the customer inputs the ticket issuing key 25. Then, the fractional cumulative amount in the fractional cumulative amount memory 35, that is, the fractional cumulative amount stored in the fractional cumulative card held by the customer, and the issued ticket J in the ticketed amount memory 36! The quasi-full amounts are compared, and if the cumulative fractional amount is greater than or equal to the ticketing standard amount, a gift certificate 100 equivalent to the amount obtained by adding the award amount to the ticketing standard amount is issued as shown in FIG. Further, in the fractional cumulative amount, an amount obtained by subtracting the ticket issue standard amount from the fractional cumulative amount before the gift certificate issuance is recorded as a new fractional cumulative amount.

Therefore, the customer to whom the gift certificate 100 was issued has been given a benefit equivalent to the benefit amount.

Incidentally, even if a customer who does not pay the bill only wishes to issue a gift certificate, the ticket can be issued by attaching the customer's fraction accumulating card to the card reader/writer 17 and inputting the ticket issuing key 25.

As described above, according to this embodiment, by issuing cards for accumulating fractions to eight customers, it is no longer necessary to pay the fractional amount of change generated in one transaction to the customers as change. Therefore, for the peripheral side, there is no need to prepare a large amount of small change as cash for change, and the time required to collect change can be shortened, and accounting operations can be made more efficient. In addition, cash management becomes easier for the customer as there is no accumulation of coins.

Moreover, the fraction of change accumulated on the fraction accumulation card is:
[When the amount exceeds a certain ticketing standard amount, a gift certificate equivalent to the amount obtained by adding the bonus amount to the ticketing standard amount can be issued, and if a gift certificate is issued, the fractional amount = 1゛ card The cumulative total amount is the ticketing J! The amount will be reduced by the equivalent amount. Therefore, by repeating shopping at a store, a customer who has a fraction accumulating card accumulates the fractional amount of change, and is thereby given a privilege equivalent to the privilege amount. Furthermore, by receiving a gift certificate, customers are given a strong impression that they have been given a special benefit, which leads to promotion of sales.

In addition, since it is now possible to set FJ'jA number unit data for each card for fractional accumulation, Il
The i-position can be selected according to the customer's request. Furthermore, when a fractional unit is entered by key input, the fractional unit by that keystroke is used preferentially over the fractional unit on the fraction accumulating card, so customers can change the fractional unit as appropriate depending on the situation. becomes possible.

Furthermore, since the date and cumulative amount of the fractional amount are printed on the printing surface of the card for fractional cumulative amounts, customers can easily check the current cumulative amount of fractional amounts at any time, and can issue gift certificates as needed. You can request it.

Next, a second embodiment of the present invention will be described in which the fractional cumulative amount for every eight customers is stored in the internal memory instead of the fractional cumulative amount.

The overall configuration of the electronic cash register in this embodiment is the same as that of the electronic cash register in the first embodiment, omitting the card reader/writer 17, card reader/writer control circuit 10, and card printer 15. The block diagram in the figure will be used and the explanation thereof will be omitted.

As shown in FIG. 11, the keyboard 12 is additionally provided with a customer key 28 for inputting the customer code assigned to each customer.

Furthermore, as shown in FIG. 12, the RAM 4 is additionally provided with a customer table 121, a customer code memory 122, and a flag memory 123 for a customer code flag CCF. However, in FIG. 3, the flag memory 3 of the card flag CF
8 is omitted.

The customer table 121 stores the total sales amount and fractional amount of change for each customer in correspondence with the customer code assigned to each customer, and includes customer code areas R1,
It is composed of a name area R2, a fractional unit area R3, a cumulative selling and discount amount area R4, and a cumulative fractional amount area R5. The customer code memory 122 is for storing and holding the customer code input using the customer key 28. The above customer code flag CCF is
When a customer code is input using the customer key 28, it is set to "1".

Therefore, when the customer key 25 of the keyboard 12 is inputted while the "registration" mode is selected and specified by the mode switch 11, the previous CPUI executes the customer key processing shown in FIG. The program is structured. That is, when the CI'UI starts customer key processing, it searches the customer code area R1 of the customer table 121.

If the corresponding customer code is set in the area R1, the customer code flag CCF in the flag memory 123 is set. Further, the assigned customer code is stored in the customer code memory 122. Next, the customer name and fractional cumulative amount corresponding to the customer code are read from the customer table 121, and the fractional cumulative amount is stored in the fractional cumulative amount area 35. Furthermore, the R/J printer 14 is driven to print the customer code and customer name on a receipt or the like, and this process is completed.

Further, while executing a process similar to the commodity transaction process of the first embodiment shown in FIG. The program has been modified to perform meter key processing. That is, when the deposit/cash total key 23 is inputted after the department registration operation of sales products is performed and the deposit closing operation by cash payment is performed, the same change calculation as in the first embodiment is executed. Then, if the calculated change amount is greater than [0] yen and the customer code flag CCF is set, that is, if change is generated by the customer's payment and the customer code is input before the closing operation. , check the state of the fractional unit flag FF. If this flag FF has been reset, the fractional unit key input setting using the fractional unit key 27 has not been performed, so the fractional unit corresponding to the customer code in the customer code memory 122 is called from the customer table 121, It is stored in the fractional unit memory 34. If the fractional unit flag FF has been set, the fractional unit key 27 has already been used to key-in the fractional number +4i and the fractional unit memory 34 has been set, so the above process is not performed.

Next, the fractional amount of change and the amount of change to be paid are calculated in the same manner as in the first embodiment, and each fraction is stored in the fractional amount memory 3.
3 and stored in the change memory 32. Also, the amount of change to be paid is displayed on the display 13.

Next, the total amount in the total amount memory 31 is added to the cumulative sales area R3 of the customer table 121 corresponding to the customer code in the customer code memory 122, and
The fractional amount in the fractional amount memory 33 is added to the fractional amount area of the interval table 121 and the fractional amount memory 35. Then, the R/J printer 14 is driven to print the total amount, deposit amount, change payment amount, fractional amount, and fractional cumulative amount on a receipt, etc., and issue a receipt as shown in FIG. Thereafter, the fractional unit flag FF is reset and this process is ended.

Furthermore, when the CPU 1 selects and specifies the "registration" mode with the mode switch 11, the keyboard 1
The program is configured so that when the ticket issue key 25 of No. 2 is inputted, the ticket issue key process shown in FIG. 15 is executed. That is, when the CPU starts ticketing key processing, it confirms that the customer code flag CCF is set, that is, that the customer code has been input using the customer key 28, and then calculates the fractional cumulative amount in the fractional cumulative amount memory 35. and the standard ticket issuing amount in the ticket issuing amount memory 36. Then, if the cumulative fractional amount is equal to or greater than the ticketing standard amount, it is possible to issue a gift certificate, so the R/J printer 14 is driven to print the receipt in a preset format to the above-mentioned ticketing base amount in the bonus amount memory 37. A gift certificate corresponding to the amount including the bonus amount is printed, and a gift certificate 100 as shown in FIG. 10 is issued. Next, a new cumulative fractional amount is calculated by subtracting the ticket issuing standard amount from the cumulative fractional amount, and the calculated cumulative fractional amount is stored again in the cumulative fractional amount memory 35. Thereafter, the fractional cumulative amount in the fractional cumulative amount memory 35 is stored in the fractional cumulative amount area of the customer table 121 corresponding to the customer code in the customer code memory 122,
This process ends.

In the second embodiment with such a configuration, the customer side issues a unique customer code to the customer at appropriate times and sets the customer code and name in the customer table 121 each time.

Further, the digit of the fraction i1 requested by the customer is stored in the fraction unit area R3.

On the other hand, the customer to whom the customer code has been issued informs store n of his customer code at the time of checkout. The clerk enters the customer code using the number keys 21 and then inputs the customer key 28.

In this state, when you perform a deposit closing operation using cash payment, if change is generated, the fractional amount of the change less than the fractional unit and the change payment amount by subtracting the fractional amount from the change are calculated, and the change payment amount is displayed. displayed on the display 13. Further, the calculated fractional amount is added to the fractional total area R4 of the customer table 121 corresponding to the customer code of the customer.

Here, if a fractional unit is entered using the fractional unit key 27 before the tightening operation, the entered fractional unit becomes valid, and if no key is entered, the customer's customer code The fractional unit of the customer table 121 corresponding to is valid.

Thereafter, if the customer requests issuance of a gift certificate, the customer inputs the ticket issuing key 25. Then, the fraction cumulative area R of the customer table 121 corresponding to the customer code of the customer
If the fractional cumulative amount stored in step 4 is equal to or greater than the ticketing standard amount, a gift certificate equivalent to the amount obtained by adding the bonus amount to the ticketing standard amount is issued. And the above cumulative fraction area R4
The amount exceeds the ticketing standard amount. Therefore, the customer to whom the gift certificate was issued was given a benefit equivalent to the benefit amount.

Note that even if a customer who does not pay the checkout only wishes to issue a gift certificate, the customer can issue the gift certificate by key-inputting the customer's customer code and then operating the ticket-issuing key 25.

In this embodiment as well, by issuing a customer code to each customer and setting that customer's customer code in the customer table 121, fractional amounts of change generated in accounting operations can be paid to the customer as change. There will be no need. Moreover, when the cumulative fractional amount of change accumulated in the customer table 121 exceeds a certain ticket issuance standard amount, a gift certificate equivalent to the amount obtained by adding the award amount to the ticket issuance standard amount can be issued, and the gift certificate is not issued. customer table 12 if
The cumulative total amount of the corresponding customer code of 1 is issued J! ■The amount will be reduced by the amount. Therefore, the same effects as in the first embodiment can be achieved.

Further, since fractional unit data can be set for each customer in the customer table 121, the unit for the fractional amount of change can be selected according to the customer's request. Moreover, when a fractional unit is input by key input, the fractional unit by the key input is used preferentially over the corresponding fractional unit data in the customer table 121, so the customer can change the fractional unit as appropriate depending on the situation. It becomes possible to do so.

Next, a third embodiment of the present invention will be described, in which the fractional amount of change in the first embodiment is directly input using a key. In this third embodiment, the fractional unit key 27 of the keyboard 12 may be changed to two fractional amount keys, as shown in FIG. Also, C shown in FIG.
A part of the PUI product transaction processing is changed as shown in FIG. 17.

That is, when the change amount is generated by the change calculation performed in response to the F13/current total key input operation of ST3, and the card flag CF is set, the input operation using the number key 21 and the fractional amount key 29 is performed. Wait for the fractional amount to be input. Then, if the PjA number amount is input, the input fractional amount is stored in the fractional amount memory 33. The subsequent steps are the same as in the first embodiment.

In the third embodiment having such a configuration, as in the first embodiment, the fractional amount of change resulting from the deposit and closing operation is accumulated on the customer's fractional accumulating card. Then, when the cumulative fractional amount exceeds a certain ticket issuance reference amount, it becomes possible to issue a gift certificate with a benefit equal to the benefit amount.

Next, a fourth embodiment of the present invention will be described, in which the fractional amount of change in the second embodiment is directly input using a key. Also in this fourth embodiment, the keyboard 12
What is necessary is to change the fractional unit key 27 to the fractional amount key 29. In addition, in the CPUI deposit/cash key processing shown in FIG. 14, the fraction unit flag FF judgment processing after confirming the setting of the customer code flag CCF is performed using the numeric key 21 and the fraction unit flag FF in the same way as in the third embodiment. The process is changed to a fractional amount key input process using the amount key 29.

In the fourth embodiment with such a configuration, as in the second embodiment, the fractional amount of change generated by the deposit/closing operation is stored in the customer table 12 corresponding to the customer code of the customer.
The cumulative total is 1. Then, when the cumulative fractional amount exceeds a certain ticket issuance reference amount, it becomes possible to issue a gift certificate with a benefit equal to the benefit amount.

Note that the present invention is not limited to the first to fourth embodiments. For example, in the first and third embodiments, a magnetic card is used as the card for adding up fractions, but an IC card may also be used. However, when an IC card is used, a card interface for connecting the connector of the IC card is required as a card data input/output section in place of the card reader/writer 17 and the card reader/writer Wlm circuit 10.

Furthermore, in each of the above embodiments, the amount of the gift certificate issued based on the cumulative fractional amount was explained as one type, but by providing a plurality of issued amount memory 36 and a plurality of reward amount memories 37 corresponding thereto, the size of the cumulative fractional amount can be reduced. This makes it possible to issue multiple types of gift certificates with different benefit scales.

Furthermore, it goes without saying that the present invention can be applied not only to a single electronic cash register but also to a POS system in which a plurality of electronic cash registers are centrally managed by a controller.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to accumulate fractional amounts of change in the waiting room, and by eliminating the trouble of giving and receiving fractional amounts as change, it is possible to simplify coin management. It is possible to provide a product sales data processing device that can be used to

Further, it is possible to provide a product sales data processing device that can provide benefits to customers using the accumulated fractional total amount and lead to promotion of sales.
