JPS5826058B2 - Registration data correction method for cash register - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a registered data correction method for a cash register that corrects data once registered in the cash register, and particularly relates to a registered data correction method for a cash register that can reliably correct registered data. .

Devices that manage money used in commercial transactions, so-called cash registers, generally store the product code of the product being sold,
We memorize and register single item data such as all types and quantities in a predetermined number of memories depending on the number of sales, print out receipts as proof of transactions and journals as transaction records, and manage the sales status at a later date using the registered data. Alternatively, inventory management and the like are performed.

Furthermore, in such cash registers, once a receipt is issued, it may be necessary to erase the transaction on the issued receipt.

This may occur, for example, when a customer returns a purchased product, or when an operator notices incorrect registration data printed on a receipt after completing all transactions for one customer.

In such a case, since the receipt serves as a transaction certificate, the receipt itself must be replaced and the previously registered data must be corrected.

However, when correcting data that has already been entered and registered in a conventional cash register, it is necessary to register all the individual item data that is entered on the previously issued receipt, which is a frequent operation. If an operational error occurs, the registered data will be erroneously corrected, making it difficult to complete the transaction as a normal transaction.

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks of the prior art, it is an object of the present invention to prevent data from being amended inadvertently by using a method for ensuring that transactions are corrected.

In order to achieve the above object, in the present invention, when all correction data is input, the total value of the single item data input in order to delete the previously registered data using information regarding the total value input earlier. After inspecting the data, the data is deleted.

The present invention will be explained below based on one embodiment.

FIG. 1 is a block diagram of an embodiment of a system to which the cash register of the present invention is applied.

In the figure, CR is a cash register, KB is a keyboard, GL is a guidance lamp, PR is a printer, MEM is a memory, and C
NT is the control unit, REG is the register, OP is the calculation unit, LC
is the line control unit, CC is the center device, FIL is the file,
LD is logging data.

The normal operation is explained as follows.

The guidance display GL of the cash register CR first displays guidance for inputting the transaction type.

The operator confirms this display and inputs the type of transaction using the keyboard KB.

For example, it is input to distinguish whether it is a cash transaction, a credit transaction using a credit card, or a transaction by a member that is automatically discounted.

By this distinguishing input, a corresponding transaction serial number is attached and supplied to the printer, the serial number is printed on the receipt by the printer PR, and registered in the memory MBM, and further
C is notified via the line control unit.

When this distinction input is completed, the guidance display GL is controlled to display input guidance for single item data by the control unit CNT.

The operator follows this input guide and enters the individual item data, the aforementioned product code, quantity, and amount data on the keyboard KB.
Input by.

This input data is printed on each printer, stored in a memory, and notified to the center device CC.

At this time, the control unit CNT calculates the amount data using the calculation unit OP to create a hard total.

At the end of this transaction, the operator presses the key labeled "Total" on the keyboard KB.

This allows the total data being calculated to be transferred to the memory MEM.
is stored in a position corresponding to the transaction serial number, and is printed on the receipt by the printer PR.

In addition, the center device CC is notified of the single item data each time it is input, and is logged as logging data LD in the area of the file FIL corresponding to the transaction serial number.

On the other hand, on the cash register CR side, as is generally known, when a total key is pressed and a key indicating payment is pressed, a drawer (not shown) is opened and a known process for receiving payment of cash or the like is performed.

Next, correction of registered transaction data according to the present invention will be explained.

The operator first presses the correction key, and since the total value of the transaction is printed on the transaction serial number to be corrected or the receipt on which the transaction serial number is printed, the operator inputs this total value using the keyboard.

In response, the control unit CNT reads the total value of the corresponding transaction serial number in the memo IJMEM and stores it in the register REGC, or notifies the center device that the data of the corresponding transaction serial number is to be corrected.

In response to this notification, the center device reads the logging data LD of the corresponding transaction serial number NOi, and stores the total value in the register RE.
Store in Ga.

If a total value is input, the total value is notified to the register REGc or the center device CC and stored in REGa.

Next, the operator inputs the individual item data printed on the receipt, including the data to be corrected, directly from the keyboard KB.

The control unit CNT accumulates this human power using the calculation unit OP.

After inputting the final single item data of the receipt, the operator presses the aforementioned "total" key.

The control unit CNT, in response to the press of the total j key, compares the accumulated total value with the total value data of the register RE G c previously input or read from the memory, file, etc. If they match, each part of the individual item data that has been accumulated and stored in the memory is subtracted from each part of the previously registered single item data.

That is, the previously registered single item data is deleted.

If, as mentioned above, the register REG in the center device CC
If the total value is stored in a, the control unit CNT
notifies the center device CC of the accumulated result via the circuit control unit LC.

In response to this, the center device CC compares the accumulated result with the value stored in the register REGa, and if they match, deletes the data of the transaction serial number NOi.

FIG. 2 is a block diagram of a main part of an embodiment of the present invention, and shows an example in which the aforementioned operator inputs the total value of receipts to be corrected from the keyboard KB.

In the figure, TK is a numeric keypad, AKG-! The correction key is pressed when a transaction to be corrected occurs.RK is the registration key, which is pressed when registering data entered from the numeric keypad TK as described below.TOK is the total key, and S
K is the inspection key, CL is the inspection stop key, 01 s G2
s G3 is a gate, AC is a correction control unit, which distributes the input data from the numeric keypad TK to various registers, and REG1JREG2 are registers, which store the input single item data and the cumulative value, respectively. RD is a memory read control unit, and COM is a comparator.

Components that are similar to those in FIG. 1 are designated by the same numbers.

In addition, the giant diagram shows a block diagram like a circuit diagram to clarify its functions, but it can also be achieved by using a known processing device such as a microprocessor, memory with a work area, and a program that can replace the function. It is possible.

Furthermore, it is assumed that transaction information having single item data to be corrected is stored in the memo IJMEM.

When performing payment, etc., the operator presses the payment key SK.

As a result, the reading control unit RD reads out each transaction data from the memory MBM and supplies it to the printer PR to print out each transaction data stored in the memory on a journal.

Normally, at this time, the read control unit RD reads and erases the data in the memory IJMEM.

In this embodiment, a stop key CL is provided to prevent the memory from being erased if the operator accidentally presses the settlement key SK, thereby stopping the reading operation.

Further, at the time of this payment, if the operator notices that there has been an erroneous input, for example, he or she presses the stop key CL and makes a correction input.

It goes without saying that the operator can manually make this correction at any time since there may be cases where the customer has returned the product.

When making a correction, the operator first presses the correction key AK.

When this correction key AK is pressed, the correction control unit A
C operates to first supply the input data of the numeric keypad TK to the register REGc by the gate G1.

At the same time, the input guidance for the total amount is provided under the control of the aforementioned guidance display or a control line (not shown).

The operator first inputs the total value of the transaction with the error on the receipt or journal using the numeric keypad TK.

This total value data is stored in register REGc.

At this point, the correction control unit AC switches the gate G1 so that the input data from the numeric keypad TK is supplied to the register REG1.

Next, the operator inputs each item data of the transaction using the numeric keypad TK.

The input single item data is stored in register REG1.

An operator inputs the product code, price, and quantity of one product as single item data by modifying the numeric keypad data using a function key (not shown), and presses a registration key RK to register each item data.

When registration key RK is pressed, gate G2 or register REG is pressed.

The single item data stored in the computer can be supplied to the arithmetic unit OP, printer PR, and memory MEM.

The calculation unit OP clears the register REG2 for each transaction, receives the amount data of the single item data of the transaction, and accumulates each amount data to create the total value of the transaction.

Also, the single item data supplied to Memo IJMEM is
The data that is successively stored in an unused area of JMEM and stored in the memo IJMBM is not allowed to be corrected at this point.

Note that the memory address for storing this is stored, for example, by the correction control unit AC.

After the operator has input all the transaction information including the corrected data to be corrected, the total key TOK is pressed.

This total key is different from the above-mentioned total key for normal transactions.
Use the same one.

When this total key TOK is pressed, the comparator CO
M is the data stored in register REGc and register REG
The accumulated data of 2 is read out and compared.

If the comparison results do not match, an alarm is output and, for example, the operator is notified by blinking the guidance display.

On the other hand, in response to the press output of the total key TOK, the gate G3 is opened, and the cumulative data of the register REG2 is stored in the address of the memory MBM instructed by the correction control unit AC via the gate G2, and is printed on the journal and receipt by the printer PR. is printed on.

If the comparison by the comparator COM results in a match, the comparator COM notifies the arithmetic control unit OP to this effect.

According to this instruction, the calculation control unit OP first writes the memo IJMB.
The data stored in register REG2 is subtracted from the so-called bird total, which is the total value of all transaction information of M, and corrected.

Next, the calculation control unit OP executes the correction control unit A of the memory IJMEM.
The data in the area indicated by C is written as minus data into the area where the normal data of the memo IJMEM is stored.

Transaction information is deleted in the manner described above.

The operator confirms that no alarm is output, enters the correct transaction data as described above, and creates a new receipt.

When printing data to be corrected, for example, print it in a different color than normal, or print a specific subtraction mark on the receipt so that it can be easily distinguished at checkout. becomes.

As described above, according to the present invention, since the area in which transaction information is stored is excluded unless the data to be corrected is definitely correct, erroneous correction can be prevented.
