Abstract

PURPOSE:To reduce the burden of a cashier when the correction of transaction contents is generated after finish operation by reprinting selling data, which are accumulated in a registration details buffer, in correspondence to the input of a transaction correcting key and executing the subtraction processing of total amount data in a buffer from a summing-up device by transaction. CONSTITUTION:When the selling data of the respective selling commodities are inputted, the selling data are accumulated to a memory and a registration details buffer 46. After that, a finish key is operated, a receipt is issued and the total amount data are added and processed by a summing-up device 42 by transaction to correspond to an input finish key. Then, the transaction or total amount data are stored to a transacting buffer 48. Then the transaction correcting key is operated, the selling data accumulated in the registration details buffer 46 are reprinted to the receipt and the total amount data in the transacting buffer 48 are subtracted from the summing-up device by transaction 42. Then, operation is returned to a condition before the input of a finish key. Thus, even when the correction of the transaction contents is generated after the finish operation, post-processing such as registration or the cancel of the registration is eliminated and the burden of the cashier can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product sales data processing device such as an electronic cash register or a Po5 (point of sale) system.

[Prior Art] Generally, an electronic cash register is provided with a plurality of closing keys for instructing closing of sales registration for each transaction such as cash transaction, credit transaction, credit sale, etc.

After the cashier completes the sales registration operation for all the products purchased by one customer, the cashier confirms the payment method with the customer and inputs the corresponding closing key. Then, the total data is printed on the receipt on which the sales data of the registered product is printed, and then this receipt is issued. Further, the above-mentioned total data is totaled for each transaction in a totalizer for each transaction formed in the memory. Note that the above transaction-specific stand is usually formed in the memory of the electronic cash register, but in the POS system, each electronic cash register (POS
It may also be formed in the memory of the file controller that manages the terminal (terminal).

By the way, some customers request to change their payment method after operating the closing key. There are also cases where the cashier does not ask the customer how to pay, or the cashier presses the wrong key and enters a different key from the customer's request. In such a case, the cashier stores the issued receipt as an error receipt. Then, it was necessary to redo the sales registration operation for all of the customer's products, enter the correct closing key, and reissue the receipt. For example, it was necessary to select the "register minus" mode after the end of business on -day and cancel registration according to the printed contents of the saved erroneous receipt.

[Problem to be Solved by the Invention] As described above, in the conventional product sales data processing device of this type, when the transaction details are corrected after the closing operation, the corresponding sales registration is redone and a correct receipt is reissued. However, after that, the registration must be canceled according to the erroneous receipt issued before the correction, which requires complicated and wasteful post-processing, placing a heavy burden on the cashier.

Therefore, the present invention makes it possible to reduce the burden on the cashier by eliminating the need for re-registration or post-processing of cancellation registration even if the transaction details are corrected after the closing operation, and the transaction details can be corrected with a simple key operation. The present invention aims to provide a product sales data processing device that can reissue correct receipts.

Furthermore, it is an object of the present invention to provide a product sales data processing device that can clearly manage erroneous receipts that occur when transaction details are corrected after a closing operation.

[Means for Solving the Problems] The present invention registers input sales data of each sales product in a memory, and registers the input sales data of each sales product in a memory, and registers the sales data according to the input of a lock key provided for each transaction such as cash transaction, credit transaction, credit transaction, etc. In a product sales data processing device that issues a receipt on which registered product data and total data are printed, and adds the total data to a totalizer for each transaction corresponding to an input lock key,
A registration details buffer that stores sales data for each sales product for one customer, a transaction buffer that stores the corresponding transaction and total data according to the input of the close key, and a transaction that commands transaction correction after the close key is input. A correction key is provided, and in response to the input of this transaction correction key, the sales data accumulated in the registered details buffer is reprinted on the receipt, and the data in the buffer is The total data is subtracted and returned to the state before the close key was input.

In addition, a series of transaction numbers that are printed on the corresponding receipt in response to the input of the transaction correction key is stored in the transaction buffer 1, and an error indication receipt with the transaction number in the transaction buffer printed in response to the input of the transaction correction key is issued. It is desirable that the

[Operation] In the product sales data processing device that takes such measures, when sales data of each sales product is input, the sales data is registered in the memory and accumulated in the registration details buffer. When the close key is operated after that, a receipt with the registered sales data and total data printed is issued, the total data is added to the transaction totalizer corresponding to the input close key, and the transaction buffer is stores the corresponding transaction and total data. When the transaction correction key is operated in this state, the sales data accumulated in the registered details buffer will be reprinted on the receipt, and the total data in the buffer will be reprinted from the transaction totalizer corresponding to the transaction in the transaction buffer. is subtracted and returns to the state before the close key was input.

Therefore, by operating the close key again, the total data is reprinted on the receipt and this receipt is issued, and the total data is added to the transaction totalizer corresponding to the input close key.

Further, when the transaction correction key is operated, an error indication receipt is issued on which the transaction number of the receipt issued before correction in the transaction buffer is printed. Therefore, the receipt with the transaction number printed on this error instruction receipt is managed as an error receipt.

[Example] Hereinafter, an example in which the present invention is applied to an electronic cash register will be described with reference to the drawings.

The mode switch 16 is used to control power on/off, select various business modes such as "registration", "checkout", "setting", "cashier minus", "manager", etc., and instruct the CPUI 1 to execute them. It is a control switch and is operated with a key.

As shown in FIG. 2, the keyboard 18 includes roOJ, which is used to enter the sales amount, number of items sold, etc.
rOJ~"9" numeric key 31, multiple department keys 32 for inputting department codes for classifying each sales item, subtotal key 33, current total key 34 for instructing closing of sales registration by cash transaction, credit Credit card key 35 for instructing closing of sales registration by credit transactions using cards etc., multiplication key 36 for instructing closing of sales registration by credit transactions, multiplication key 3
In addition to various keys such as 7, the above-mentioned cash key 34, trust key 35. A transaction correction key 38 is provided for instructing transaction correction after inputting a close key such as the multiplication key 36.

The display unit 20 displays the department code of the sales product that has been key-input,
This is a dot display that can electronically display numeric data such as the total sales amount and character data such as error messages, and a cashier's display and a customer's display are provided at the front and rear.

Further, as shown in FIG. 3, the RAM 14 includes a departmental totalizer 41 that totals the number of sales items and sales amount of each sales product by department code, and a department totalizer 41 that totals the total points and total amount of customer service by transaction code. A transaction totalizer 42, a window counter 43 for calculating the total number and total price of products sold to - customers, and a registration flag F1 that is set to "1" during registration of - customers. In addition to a flag memory 44, a counter memory 45 for a receipt number counter N that specifies a series of receipt numbers (transaction numbers) to be printed on receipts, etc., the department code, number of sales items, sales amount, and print editing data of each sales product are stored. Registration details buffer 4 that accumulates for one customer
6. Counter memory 4 of a detail buffer counter M that specifies the data storage address of the registration detail buffer 46.
7. A transaction buffer 48 is formed which stores a corresponding transaction code, total score 2 total amount, receipt number, and a document flag F2 indicating whether or not the document print type is selected according to the input of the closing keys 34, 35, and 36. There is.

With the "registration" mode selected by the mode switch 16, the CPU II executes the sales registration process for one customer according to the flowchart of FIG. 4 using the program in the ROM 13. That is, ST(
Step) As step 1, when the sales amount is entered using the number keys 31 on the keyboard and the department code is input using the department key 32 to register the department of the sold product, whether this product is the customer's first registration or not. It is determined from the state of the registration flag F1 in the flag memory 44. If the registration flag F1 is reset to "0", this is the first registration, so the window sill instrument 43. The registered details buffer 46 and transaction buffer 48 are cleared to zero. Further, the detailed buffer counter M of the counter memory 47 is initialized to "1". Then, the registration flag F1 is set to "1" and the process proceeds to ST2. On the other hand, if the registration flag F1 is set to "1", it is the second or later registration, so the detail buffer counter M is updated by +1 and ST
Proceed to 2.

In ST2, normal departmental registration processing is executed.

That is, the number of sales items and sales amount of the product registered in ST1 are added to the number of sales items and sales amount of the corresponding department code in the departmental totalizer 41.

Next, in ST3, the number of items sold and the sales amount are added to the wealth meter 43. In addition, the department code and sales amount are displayed on the display unit 20, and print data for receipts and journals is edited from the department code, number of items sold, sales amount, etc., and the printer 22 is driven to print on receipts and journals. Let's do it. After that, the department code, number of sales items, and
The sales amount and print editing data are stored in ST.
Return to I.

On the other hand, there is no department registration in STI, and current key 34. Shinkei key 35. When a closing key such as the multiplication key 36 is operated, after confirming that the registration flag F1 is set to "1", the total score and total amount calculated by the wealth meter 43 are displayed as ST6. 20 and also prints on receipts and journals. Next, in ST7, normal transaction-specific registration processing is executed.

In other words, the total score and total amount are calculated by transaction totalizer 42.
Add to the number of sales points and sales amount of the transaction code corresponding to the input key in . Further, in ST8, the receipt number counter N of the counter memory 45 is printed on the receipt and journal as a receipt number, and only the receipt is issued.

At this time, a stamp with the store name, logo, etc., and the date read from the clock circuit 15 are printed in advance on the receipt to be issued to the next customer.

Next, if the input lock key is the dipping sauce key 35, printing is performed on the credit slip, so in ST9 the printer 22
After confirming that the slip paper is inserted, print the slip data such as the total amount on the slip.

Thereafter, the transaction code corresponding to the input key, the total score and total amount in the word totalizer 43, and the receipt number in the receipt number counter N are stored in the transaction buffer 48 as 5TIO. Furthermore, in the case of a tightening operation using the dipping key 35, the slip flag F2 is set to "1", and in the case of a tightening operation using another tightening key, the flag F2 is set to "0".
”.Then, as 5TII, the receipt number counter N is updated by +1, and the registration flag F1 is set to “
0" and return to ST1.

Further, when the transaction correction key 38 is input while the "manager" mode is selected by the mode switch 16, the CPU 11 executes transaction correction processing for one customer according to the flowchart of FIG. 5 by the program in the ROM 13. Execute. That is, when the flowchart is started and it is confirmed that the mode is "manager" and that the registration flag F1 is reset to "0", a message such as "receipt correction in progress" is displayed on the display unit 20 as 5T21. . Next, as 5T22, the receipt number in the transaction buffer 48 is called, the printer 22 prints it on the receipt and the journal, and the receipt is issued as an error indication receipt (error indication receipt issue control means).

At this time, printing a stamp and date on the receipt for the next customer is the same as when issuing a normal receipt.

Next, as 5T23, the print editing data accumulated in the registered details buffer 46 is sequentially called out in the order of accumulation, and the printer 2
2 to reprint on receipts and journals (
Receipt reprint control means). Also, as 5T24, the totalizer 4 for each transaction corresponding to the transaction code in the transaction buffer 48
The total number of points and total amount in the transaction buffer 48 are subtracted from the number of sales points and the total amount of sales of ``2''. Also, 5T25
Check the slip flag F2 in the transaction buffer 48 and set it to “1”.
”, after confirming that the issued slip has been inserted into the printer at 572B, the characters “correction” are reprinted on this issued slip. Then, as 5T27, the transaction buffer 48 is cleared to zero, and the registration flag F1 is set to "1".
If the department code and the number of sales items in the address area that match the detail buffer counter M of the registration detail buffer 46 are displayed on the display section 20, and the state is returned to the state before the closing key was input in the sales registration process (transaction correction processing means ), this process ends.

In this embodiment configured in this manner, when the department registration of all products purchased by a customer is performed in sequence, the number of sales items and sales amount for each quadruple is registered in the department totalizer 41 for each department. At the same time, the wealth meter 54 calculates the customer's total score and total amount. In addition, the department code, number of sales items, sales amount, etc. of the product registered in the department are printed on the receipt and journal, and the print editing data is sequentially stored in the registered details buffer 44 along with the corresponding department code, number of sales items, and sales amount. be done.

After that, when the registration and closing by credit transaction is commanded by operating the dipping sauce key 35, for example, the richness meter 43
The total points and total amount calculated in step 1 are added to the sales points and sales amount of the transaction code (for example, 0003) corresponding to the dipping sauce key 35 in the transaction totalizer 42.

Further, the total score, the total amount, and the receipt number of the receipt number counter N are printed on the receipt and the journal, and a receipt 50 as shown in FIG. 6 is issued.

Further, since it is a credit transaction, by inserting the slip paper into the printer 22, slip data such as the total score, total amount, amount, etc. is printed on the slip paper. Further, the corresponding transaction code, total points, total amount, and receipt number are stored in the transaction buffer 48, and the slip flag F2 is set to "1", allowing the next customer to register for sales.

At this time, if the current customer requests to correct the transaction details from credit transaction to cash transaction, the cashier will press the mode switch 16.
After selecting the "manager" mode, the user operates the transaction correction key 38 to instruct correction of the transaction details. Then,
With the message “Receipt being corrected” displayed on the display unit 20, first check the receipt 50 issued to the current customer.
The receipt number is called from the transaction buffer 48 and printed on the receipt and journal, and this receipt is
It is issued as an error instruction receipt 51 as shown in the figure. Subsequently, the print editing data in the registration details buffer 46 is sequentially called out in the order of accumulation and printed on receipts and journals. That is, the same data as that printed on the receipt 50 is printed again on the receipt and journal by the customer's department registration. In addition, totalizer 42 for each transaction
The total number of points and total amount in the transaction buffer 48 are subtracted from the number of sales points and the total amount of sales corresponding to the important code in the transaction buffer 48 at The total amount of data added will be canceled. Therefore, the cashier manages the erroneous receipt 50 by pairing the issued receipt 50 as a transaction before correction with the erroneous instruction receipt 51. Further, the slip that was printed as a credit transaction before the transaction correction is inserted into the printer 22. Then, the words "correction" are printed on the slip, so the cashier invalidates the slip.

Thereafter, the display section 20 displays the department code and sales amount of the product for which department registration was last performed before the transaction correction, so the cashier can use the closing key requested by the customer, that is, in this case, the current total key 34. key operation. Then, the total points and total amount in the wealth meter 43 are added to the sales points and sales amount of the transaction code (for example, 0001) corresponding to the current total key 34 in the transaction-by-transaction totalizer 42.

Further, the total score, the total amount, and the receipt number of the receipt number counter N are printed on the receipt and journal, and a receipt 52 as shown in FIG. 8 is issued.

Further, the transaction buffer 48 contains the corresponding transaction code, total points, and total amount.

The receipt number is stored and the slip flag F2 is “0”
will be reset and the next customer can register for sales.

Therefore, according to this embodiment, when changing the details of a transaction after a closing operation, first select the "manager" mode with the mode switch 16 and operate the transaction correction key 38, and then change the mode switch 16 to "register" mode. ” mode and then operate the lock key corresponding to the corrected transaction, so the operation is simple. Moreover, without having to redo the sales registration operation for all the customer's products, a receipt 52 with the same sales data as the erroneous receipt 50 printed and only the transaction details corrected can be issued, so a single correct receipt can be generated in a short time. can be reissued, eliminating the risk of keeping customers waiting. Furthermore, since there is no need to perform cancellation registration using the erroneous receipt 50, the burden on the cashier can be significantly reduced.

In addition, an error instruction receipt 51 is printed with the receipt number of the error receipt 50 in response to a key operation of the transaction correction key 38.
is issued, so by pairing the instruction receipt 51 with the error receipt 50, the error receipt 50 can be managed reliably and fraud by the cashier can be prevented.

In addition, after operating the transaction correction key 38, the mode switch 16
When returning to the "registration" mode, additional products can be registered by registering sales products without pressing the lock key.

In the above embodiment, the case where a product is registered in a department is exemplified, but even in the case of other single item registration or PLU (Price Lookup) registration, the code accumulated in the registration details buffer 46 is not registered in the department. It is applicable because the code simply becomes a single item code or a PLU code. It goes without saying that the present invention can also be applied to POS systems. Furthermore, the timing for printing the registration data of the sales item on the receipt may be such that it is printed in accordance with the contents of the registration details buffer 46 after the closing key is operated. It goes without saying that various other modifications can be made without departing from the spirit of the invention.

[Effects of the Invention] As detailed above, according to the present invention, even if the transaction details are corrected after the closing operation, it is possible to reduce the burden on the cashier by eliminating the need for post-processing of re-registration or cancellation registration. Moreover, it is possible to provide a product sales data processing device that can reissue a correct receipt with corrected transaction details by only a simple key operation.

Further, according to claim 2, there is an effect that the management of erroneous receipts that occur when the transaction details are corrected after the closing operation can be clearly managed.
