Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a merchandise sales data processing device capable of managing an operator.

[0002]

2. Description of the Related Art In a store where a large number of store staff (cashers or customer service representatives) are operating as operators who operate electronic cash registers for registering product sales data, such as discount registration and return product registration. If anyone can freely perform processing that reduces the sales data, the operator may misuse the processing to perform fraud.

Since this kind of fraud is easily carried out if the discount amount and the return amount are limited, the conventional electronic cash register can set the maximum amount of the discount amount or the return amount for each customer once or once. It is set, and only discounts and returned goods registration below this limited amount are possible.

[0004]

However, since the limit amount of discounts and returns set in the electronic cash register is commonly applied to all operators, the limit amount of registration operation depends on the years of experience of the operator. It was not possible to perform fine-grained management, such as setting any of.

Therefore, the present invention is intended to provide a product sales data processing device capable of finely managing the limit amount of registration operation for each operator.

[0006]

According to the present invention, there is provided a product sales data processing device having a card reader for reading data from a card and storing product sales data obtained by a product registration operation in a storage unit. In the above, there is provided a limit amount information recognizing means for recognizing limit amount information by the registration operation stored in the card, and a registration operation inhibiting means for inhibiting a registration operation exceeding the limit amount recognized by the recognizing means. ..

[0007]

According to the present invention having such a configuration, by storing the limit amount information of the registration operation in association with the operator in the card possessed by each operator, the operator can perform the registration operation exceeding the limited amount. The operation becomes invalid. Therefore, the limit amount of registration operation can be determined for each operator under different conditions.

In the RAM 34, as shown in FIG. 4, a return flag F1 indicating "1" indicating that the product is registered for return, a registration flag F2 indicating "1" indicating that the product is being registered, and a card in the card reader / writer 15. A flag memory 51 that stores a card flag F3 or the like that indicates that "1" is attached,
The register register 52 for temporarily storing the register data, the amount totalizer 53 for calculating the total amount of the products sold to one customer, and the sales data (sales amount, returned goods) of each product registered in the electronic cash register. From the operator registration card 54 and the product registration file 54 for totaling the amount (discount amount, discount amount, etc.) for each department and transaction (cash payment sales registration, card payment sales registration, returned goods registration, discount registration, etc.) Area C for storing card number, operator name, operation limitation flag, and limit amount data which are read information
A card data buffer 55 including 1 to C4 and a card registration data area C5 for temporarily storing the sales data obtained by the registration operation when the operator card 42 is not attached to the card reader / writer 15. Are formed.

As shown in FIG. 5, the operator card 42 has a memory 61 of a card number set as unique information of the operator card, a memory 62 for storing an operator name, a daily total and total sales by transaction. Transaction-specific registration files 63, 64 for storing data, operation keys for registering by a predetermined key such as a return key 22, a discount key 23, a cancel key 24, and permission / prohibition of operation in each business mode are stored. Memory 65, memory 66 for storing limit amount data for registration operation such as return amount for one return or one customer in return registration, discount amount for one time or one customer in discount registration, operation of electronic cash register A memory 67 for storing the time zone for permitting is added.

After the predetermined initial processing is completed by turning on the power, the CPU 31 executes the main routine according to the flow charts shown in FIGS. 6 and 7. That is, as step (hereinafter abbreviated as ST) 1, it is determined whether or not a card (operator card 42 or customer card 43) is inserted in the card reader / writer 15, and if not inserted, the card flag F3 is set to " It is determined whether or not it is set to "1", and if it is not "1", the process proceeds to ST2.

When the card flag F3 is "1", it means immediately after the card is removed.
To judge. If the registration flag F2 is "1", it means that the card has been removed during the product registration. Therefore, the card flag F3 is reset to "0" and the process proceeds to ST2.

If the registration flag is not "1", it means that the card is removed after the registration is completed. Therefore, the signal from the second selection switch 27 is read, and if it is an ON signal, the predetermined data in the card data buffer 55 is read. Areas C3 and C storing the operation limitation flag and the limit amount data as
After clearing 4, the card flag F3 is reset to "0" and the process proceeds to ST2.

When the card is removed after the registration is completed by turning on the second selection switch 27, the predetermined area C
When C3 and C4 are cleared, the operation is prohibited until the next card is inserted.

On the other hand, when the card is inserted in ST1, it is judged whether or not the card flag F3 is set to "1". If "1", the process proceeds to ST2, and if not "1". Immediately after the card is loaded, the data is read from the card to determine whether it is the operator card 42 or the customer card 43. And customer card 4
If it is 3, the card flag F3 is set to "1" and ST
Go to 2.

On the other hand, in the case of the operator card 42, it is determined whether or not the card number read from the card and the card number stored in the area C1 in the card data buffer 55 match.

If the card numbers match, it means that the once removed card is re-installed. Therefore, the data in the area C5 in the card data buffer 55 (according to the registration performed while the card is removed) The obtained sales data) is added to the daily total and cumulative transaction-specific registration files 63 and 64 of the operator card 42, respectively, and the area C5 is cleared.

At this time, when the second selection switch 27 is ON, the cleared operation limitation flag and limit amount data are read from the card 42 and re-input. Then, set the card flag F3 to "1" and ST2
Go to.

If the card numbers do not match, after confirming that the area C5 of the card data buffer 55 is empty, the respective data read from the card 42 are respectively placed in the predetermined areas C1 to C4 of the card data buffer 55. After storing, the card flag F3 is set to "1" and the process proceeds to ST2.

In ST2, the signal from the first selection switch 26 is read to determine whether it is ON or not. If it is OFF, the process proceeds to ST3. If it is ON, the process returns to ST1 if the card is not inserted, and if the card is inserted, the permission time zone data is read from the card and compared with the current time, and the current time is within the permission time zone. If so, the process proceeds to ST3, and if it is outside the permitted time period, the process returns to ST1.

In ST3, it is determined whether or not there is a key input from the keyboard 12, and if there is no key input, the process returns to ST1. If there is a key input, the process proceeds to ST4.

At ST4, the business mode selected by the mode switch 25 is determined. Then, in the registration mode, the type of the key is determined, and the processing corresponding to the input key as shown in FIGS. 8 to 11 is executed.

In the inspection mode, the inspection work operation flag of the operation limited flag on the card is recognized, and if the flag is set to "1", the process proceeds to the inspection process and "1".
Otherwise, inspection processing is prohibited.

In the cash register minus mode, the cash register minus operation flag of the operation limitation flag in the card is recognized. If the flag is set to "1", the cash register minus process is started. Register minus processing is prohibited.

Each flag is recognized by reading the corresponding flag from the card when the card is inserted, and by reading the corresponding flag in the card data buffer 55 when the card is not inserted.

FIG. 8 is a flow chart showing the department key processing in the registration mode. When the department key processing is started, after confirming that the number data is stored in the number register 52, it is determined in ST5 whether the return flag F1 is set to "1". Here, the return flag F1 is "1".
If so, the return registration process is performed, and if it is other than “1”, the sale registration process is performed.

In the case of sales registration processing, registration flag F2
Is set to "1", and the number data in the number register 52 is added to the amount totalizer 53 as the sales amount of the sale product,
The sales amount, sales points, etc. are cumulatively registered in the corresponding department in the sales registration file 54 for each department, and the department code, the sales amount, etc. are displayed on the displays 14 and 17, and the printer 3
At 8, the printout is printed on the receipt and the process ends.

In the case of return registration processing, the return limit amount as the limit amount data on the card is recognized, and it is determined whether or not the number data is less than or equal to this limit amount (limit amount information recognizing means). Then, if the number data is larger than the limit amount, it is judged as an error and the returned goods registration process is prohibited (registration operation prohibiting means).

If the number data is less than the return limit, the registration flag is set to "1" because the return registration process is permitted, and the number data is returned as the return amount from the total amount in the amount totalizer 53. The amount is subtracted, the return amount is subtracted from the sales amount of the relevant department in the department file in the sales registration file 54, and the returned amount is added to the return transaction memory of the transaction file.

Next, it is judged whether or not the operator card 42 is inserted into the card reader / writer 15, and if it is inserted, the return transaction memory of the daily total and accumulated transaction-specific registration files 63, 64 of the card. If the card is not inserted, the return amount is added to the return transaction memory in the card registration data in the card data buffer 55.

Thereafter, the relevant department code and the amount of returned goods (minus display) are displayed on the displays 14 and 17, and the relevant department code, the amount of returned goods and the symbol "return" are printed on the receipt, and the return flag F1 is set to "0". To reset and exit.

FIG. 9 is a flow chart showing the return key processing in the registration mode. When the return key 22 is input in the registration mode, the return key operation limitation flag of the operation limitation flag on the card is recognized. If the flag is not "1", it is an error because the input of the return key 22 is prohibited. If the flag is "1", the input of the return key 22 is permitted, and therefore the return flag F1 is set to "1". Set and finish.

FIG. 10 is a flow chart showing the discount key processing in the registration mode. Discount key 23 in registration mode
Is input, the number data is stored in the number register 52, the registration flag F2 is set to "1", and the number data is less than or equal to the amount in the amount totalizer 53. After confirming, the discount key operation limitation flag of the operation limitation flag on the card is recognized.

If the flag is not "1", it is an error because the input of the discount key 22 is prohibited.
If the value is "1", the discount key 22 is permitted to be input, and the process proceeds to the discount registration process.

Next, the discount limit amount as the limit amount data on the card is recognized, and it is judged whether or not the number data is less than or equal to this limit amount (limit amount information prohibiting means). If the number data is larger than the limit amount, it is determined as an error and the discount registration processing is prohibited (registration operation prohibition means).

When the number data is less than or equal to the discount limit amount, it is determined that the discount registration processing is permitted, and the number data is used as the discount amount to subtract the discount amount from the total amount in the amount totalizer 53.
And the discount amount is added to the discount transaction memory of the transaction-specific file in the sales registration file 54.

Next, it is judged whether or not the operator card 42 is inserted in the card reader / writer 15, and if it is inserted, the discount transaction of the daily total and cumulative transaction registration files 63, 64 of the card is made. The discount amount is added to the memory, and when the card is not inserted, the discount amount is added to the discount transaction memory in the card registration data in the card data buffer 55. After that, the discount amount (negative display) is displayed on the display devices 14 and 17, and the discount amount and the symbol "discount" are printed on the receipt to finish the process.

FIG. 11 is a flow chart showing deposit / cash total key processing in the registration mode. When the deposit / cash total key 20 is input in the registration mode, after confirming that the registration flag F2 is set to "1", it is determined whether or not the register data is stored in the register register 52. ..

If the number data is present, it is confirmed that the number data is the deposit amount and the total amount is equal to or larger than the total amount in the amount totalizer 53, and the amount is stored in the cash settlement transaction memory of the sales registration file 54 for each transaction. The total amount of money in the totalizer 53 is added.

Next, it is judged whether or not the operator card 42 is inserted in the card reader / writer 15, and if it is inserted, the cash settlement transaction of the daily total and accumulated transaction-specific registration files 63, 64 of the card. The total amount is added to the memory, and when the card is not inserted, the total amount is added to the cash settlement transaction memory in the card registration data in the card data buffer 55.

Thereafter, the total amount of money is displayed on the indicators 14 and 17, and the drawer 16 is opened. In addition, the total amount, deposit amount, and change amount are printed on the receipt as required, and further, the operator name on the card is recognized, the receipt number, and the current time are printed on the receipt,
The receipt is issued from the receipt issuing port 13. After that, the registration flag F2 is reset to "0", the amount totalizer 53 is cleared, and the process ends.

In the electronic cash register of this embodiment having such a configuration, each operator has an operator card 42, and when operating the electronic cash register, his or her own card 42 is used as a card reader / writer. Insert into 15 and start operation.

When the return key 22 is operated to register the return, if the return key operation limitation flag of the card 42 is "1" and the return amount is less than or equal to the return limit amount of the card 42. Returns registration processing is allowed. Then, the return amount at this time is the transaction registration file 6 of the card 42.
Accumulated in return transaction memory within 3,64.

Similarly, in the case of discount registration by operating the discount key 23, the discount key operation limitation flag of the card 42 is "1" and the discount amount is less than or equal to the discount limit amount of the card 42. If so, the discount registration process is permitted, and the discount amount at this time is accumulated in the discount transaction memory in the transaction-specific registration files 63 and 64 of the card 42.

As described above, in the present embodiment, it is possible to set the maximum amount for the return amount at the time of return registration and the discount amount at the time of discount registration for each operator card 52. Therefore, the administrator can set the limit amount data arbitrarily according to the years of experience of the operator and the like, and thereby it is possible to limit the return amount at the time of return registration or the discount amount at the time of discount registration for each operator. Therefore, it becomes possible to easily perform fine-tuned management such as setting individual limits such as the amount of returned goods at the time of return registration and the discount amount at the time of discount registration, depending on the number of years of experience of the operator. Can be expected.

Although the operator card 42 has a function of accumulating sales data of transactions registered by itself in the above embodiment, it goes without saying that the effect of the present invention can be obtained without this function. .. In this case, it goes without saying that a card reader dedicated to reading card data can be used instead of the card reader / writer 15.

[0055]

As described above in detail, according to the present invention, the limit amount information by the registration operation is stored in the card possessed by each operator in association with the operator, and the registration operation exceeding the limited amount is invalidated. Therefore, it is possible to provide a product sales data processing device capable of finely managing the limit amount of registration operation for each operator.
