Abstract

PURPOSE:To execute a transaction stop processing, as well to transaction for which a finishing processing is executed with a simple operation by providing a recovery processing means to execute a recovery processing to a summing-up memory and a printing control means to print it to a receipt that printing contents are ineffective. CONSTITUTION:In order to stop this time transaction after this time finishing processing, the stop of the transaction is instructed by a stop instructing means (c). A recovery means (d) reloads the total number of sales by sectors including the sales up to this time transaction in a first storing means (a) to the total number of the sales by sectors in the first storing means (a) at the finishing processing time point of this time transaction in a second storing means (b). On the other hand, when it is detected by a detecting means (e) that the receipt for this time transaction issued by this time finishing processing is set in a prescribed position, it is printed to the receipt by a printing control means (f) that the contents printed to the receipt are ineffective. Thus, the transaction stop processing to the transaction, for which the finishing processing is executed, can be also executed by the simple operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to transaction cancellation processing in a sales data processing device such as an electronic register.

[Prior Art] In an electronic register, each time sales data is input to -a, cumulative values such as the total number of sold items for each product in a cumulative memory are updated and registered, and the sales details for - transactions are updated. Data is sequentially stored in one transaction memory and receipts are printed sequentially.

By the way, if a cancellation of a transaction is instructed for a transaction that has already been registered, the amount of the transaction for which the cancellation was instructed is subtracted from the cumulative value in the cumulative memory, and a receipt for the canceled transaction is also generated. It is necessary to print a message to the effect that the printed content is invalid.

In this case, if an instruction is given to cancel a transaction during registration, the sales detail data related to that transaction is stored in the transaction memory and has not been cleared.
- Based on the sales detail data in the transaction memory, the cumulative data in the cumulative memory can be updated to cancel transactions without re-entering each sales data by subtracting the contents of the corresponding cumulative data in the cumulative memory. The content has been restored to one that does not include transactions. Furthermore, since the receipt with the sales detail data for the canceled transaction was still set, a message was printed on the set receipt to the effect that the printed content was invalid.

[Problem to be solved by the invention] However, when an instruction is given to cancel a transaction after closing,
Since the sales detail data related to that transaction has already been cleared in one transaction memory, the restoration process to the cumulative memory must be performed by a reversal process that requires re-input of each sales data of the input input related to the transaction cancellation. was troublesome.

Furthermore, since the receipt on which the sales detail data for the transaction related to the canceled transaction was printed had already been issued due to the closing process, it was not possible to print on the receipt that the printed content was invalid.

An object of the present invention is to enable a transaction cancellation process for a transaction that has been finalized to be performed with a simple operation.

[Means to solve the problem] The means of this invention are as follows.

The first storage means a (see the functional block diagram of FIG. 1, the same applies hereinafter) sequentially stores the input sales data.

The second storage means (a) stores predetermined data that is utilized to restore the cumulative data in the first storage means (a) to contents that do not include the amount of canceled transactions.

The cancellation instructing means C instructs to cancel the transaction.

When a cancellation instruction is given by the cancellation instruction unit C, the restoration processing unit d stores the accumulated data in the first storage unit a based on predetermined data in the second storage unit a for the transaction cancellation. Revert to content that does not include.

The detection means e detects whether or not a receipt is set in a predetermined position when a transaction cancellation is instructed by the cancellation instruction means C.

When the detection means e detects that a receipt is set at a predetermined position, the printing control means f prints on the receipt that the contents printed on the receipt are invalid.

[Action Co. The operation of the means of this invention is as follows.

Now, the second storage means stores the contents of the first storage means a immediately before starting to input the sales data of, for example, departmental products related to the current transaction, that is, the contents of the first storage means a at the time of closing processing of the previous transaction. It is assumed that the total number of sales for each department is stored in the storage means a of 1.

Then, in this state, we entered the sales data for each department related to this transaction, and as a result of the closing process, the first
The total number of sales for each department in storage means a has been updated to a value that includes the amount up to the current transaction, and in this state, that is, after the current closing process, in order to cancel the current transaction,
It is assumed that the cancellation instruction means C instructs to cancel the transaction.

Then, the return processing means d stores the total number of sales for each department, including those up to the current transaction, in the first storage means a.
It is rewritten to the total number of sales for each department in the first storage means a at the time of closing of the previous transaction in the second storage means a.

Through this rewriting process, the contents of the first storage means a are restored to a state that does not include the current transaction amount related to the transaction cancellation.

On the other hand, when the printing control means f detects that a receipt for the current transaction issued by the current closing process is set in a predetermined position by the detection means e,
The content printed on the receipt, that is, the fact that the sales detail data for the canceled transaction is invalid is printed on the receipt.

Therefore, transaction cancellation processing for transactions for which closing processing has been performed can be performed with a simple operation.

[Example] An example will be described below with reference to FIGS. 2 to 5.

FIG. 2 is a block configuration diagram of the sales data processing device, in which the CPU performs various processing on the sales data input from the key human power section 2 according to a program stored in advance in the ROM 3, and stores the processing results in the RAM 4. , displays on the display section 5, prints on the printing section 6, and other processes.

The input control unit 7 scans the key operation status of the key manual unit 2, generates a code corresponding to the operation key, and sends the code to the CPU.
Output to I. In addition, the display control section 8 and the print control section 9 are
A display signal and a print signal are generated in accordance with the data (code) to be displayed and printed, and are displayed on the display section 5 and printed on the printing section 6.

K. - Human power section 2: Setting (P), Registration (R), Power OFF
F, mode changeover switch SW1 for changing and setting each mode of inspection (X) and settlement (Z), receipt switch SW2 for instructing whether or not to issue a receipt, number key 2
In addition to a, there are function keys such as a department key 2b, a cash/deposit key 2c, and a cancel key 2d for instructing cancellation of a transaction. Note that when the cash/deposit key 2c is operated, the CPU performs the following functions: - Calculating the total amount of the transaction;
In addition to executing transaction closing processing such as calculating change, it also opens a drawer 10 for storing money.

The RAM 4 includes a departmental memory Ml that cumulatively stores the total number of sales, total sales amount, etc. for each department, a transaction memory M2 that stores transaction sales detail data, and a save memory M.
Various types of memories such as No. 3 are formed.

When the first sales data for -transactions is input to this save memory M3, the departmental memory M3 at that time is stored.
1, that is, the total number of sales by department and the total sales amount by department for transactions up to the previous time are transferred. Note that when the transfer is performed, the cancellation processing permission flag F1 in the CPUI is set. When the above-mentioned save memory M3 is instructed to cancel the current transaction, the total sales quantity and total sales amount in the departmental memory M1, which were updated by the current transaction related to the cancellation, are restored to the contents up to the previous transaction. It is used to make things happen.

The printing section 6 includes a receipt/journal printing section 6a and an authentication printing section 6b. The authentication printing section 6b has a sensor 6bb for detecting paper placed on a slip table for authentication printing (not shown), and the sensor 6bb detects the paper under predetermined conditions. In this case, a message is printed to the effect that the printed content on that paper is invalid. Further, the authentication print is printed by the print head 6aa for receipt print and the print head 6ab for journal print.

Note that when a cancellation is instructed for a transaction for which a receipt has not been issued, the CPUI has a cancellation printing prohibition flag F2 that indicates that printing of cancellation on the receipt side by the receipt print head 6aa is prohibited. are doing.

Next, the operation of the embodiment will be explained with reference to FIGS. 3 to 5.

Under the registration mode, the CPU first waits for a key operation (step S1), and when a key operation is performed, it determines whether it is a registration operation (step S2). If so, it is determined whether or not this is the first registration operation for a transaction (step S3). If it is the first registration operation, the current data in the departmental memory Ml, that is, the previous transaction. Copy the total sales quantity and total sales amount of each department up to the minute to the save memory M3 (step S4), and set the cancellation permission flag F (step S4).
Step 55) Next, based on the data input by the above registration operation, update the total number of sales and total sales amount of the corresponding department in the department memory M1, and store the input data in the one transaction memory M2. Then, print the receipt of that person in the receipt/journal printing section 6a.
Print the journal (see Figure 4 (R1) and (Jl))
A series of registration processes such as the following are performed (step S6), and the process returns to step S1.

If it is determined in step S3 that this is not the first registration operation, the process immediately advances to step S6 to execute registration processing.

If it is determined in step S2 that it is not a registration operation, it is determined whether or not it is a closing operation by operating the cash/deposit key 2C (step S7).

As a result, if it is a closing operation, the receipt switch SW2
A series of closing processes such as issuing a receipt and clearing the contents of the transaction memory M2 are performed (step S8), and the process returns to step S1.

On the other hand, if it is determined that the closing process is not repeated, cancel key 2
It is determined whether or not the operation is a cancellation of one transaction by the operation d (step S9). As a result, if it is a cancellation operation of a transaction, it is determined whether or not the cancellation processing permission flag F is set, that is, the evacuation is performed. Determine whether the total number of sales and total amount of sales for each department up to the previous transaction have been saved in the memory M3 (step SIO>). If there is a cancellation operation after the closing process,
It is determined whether or not receipt issuing processing is being performed (step 512). As a result, when receipt issuing processing is being performed, it is determined whether or not paper is placed on the slip table based on the sensor 6bb. In step 813), if the paper is placed, the process proceeds to step S16.In the above judgment, it is simply determined whether or not a sheet is placed, and the sales detail data related to the previous transaction is printed on the sheet. The operator determines whether or not it is a receipt.

On the other hand, when the receipt issuing process is not being performed, a cancellation printing prohibition flag F2 is set in order to prohibit cancellation printing on the receipt side by the receipt print head 6aa (step 514).

If it is determined in step Sll that the cancellation operation is before the closing process (during registration), the receipt switch SW2
Determine whether or not is turned on (step 515)
As a result, if the receipt switch SW2 is turned on, the process proceeds to step S16, and if it is not turned on, it means that the receipt is not being printed, so in step S14, the cancel printing prohibition flag F2 is set. After setting, the process advances to step S16.

In step S16, a message indicating that the transaction has been canceled is printed. In this case, as shown in FIG. 4 (R1) and (Jl), if a cancellation operation is performed during registration during which both journal printing and receipt printing are being performed, the cancellation printing prohibition flag F2 is reset. Figure 4 (R2
), (J2), cancellation printing is performed on both the receipt and journal receipt. Also,
As shown in Figures 5 (R1) and (Jl), when both journal printing and receipt printing are performed and a transaction is canceled after the closing process, Figure 5 (R2) and (
As shown in J2), cancellation printing is similarly performed on both the receipt receipt and the journal receipt.

When such cancellation printing is completed, it is determined whether the registration is in the middle or not (step 517). As a result, if the registration is not in the middle but after the closing process, the process proceeds to step S20. If it is on the way, receipt switch S
Determine whether W2 is turned on (step 51
8) As a result, when the receipt switch SW2 is turned on, a receipt is issued in which the sales detail data that is currently being registered is canceled and printed, as shown in Figure 4 (R2). , proceed to step S20.

If the receipt switch SW2 is not turned on, the process directly advances to step S20.

In step S20, the contents of the departmental memory M1 are rewritten to the contents of the save memory M3. Through this rewriting process, the contents of the departmental memory M1 are restored to the contents up to the previous transaction, which does not include the sales data for the current transaction for which the transaction was cancelled.

Next, while resetting the cancellation processing permission flag F1,
If the cancel printing prohibition flag F2 is set, it is also reset (step 521) and the process returns to step S1.

If it is determined in step S9 that the operation is not a transaction cancellation operation, other processing is performed according to the key operation (step S9).
22) In step SIO, the cancellation processing permission flag F
If it is determined that 1 has been reset, error handling is performed (step 823) and the process returns to step S1.

In this way, one transaction can be completely canceled with a simple operation not only during registration but also after closing.

Note that the present invention is not limited to the above-described embodiments, but can also be applied to, for example, a POS terminal that reads barcodes with a scanner and inputs sales data. In addition, the sensor 6bb is configured with an optical character reading function, and the series of Nα printed on the receipt receipt is read to determine whether the paper placed on the slip table is the receipt issued immediately before. Furthermore, instead of the transaction memory M2,
By forming a memory that stores sales detail data for multiple transactions and configuring the sensor 6bb with an optical character reading function, it is possible to cancel not only the previous transaction but also multiple previous transactions in the same way. It is. In addition, the sensor 6b
b is configured with a barcode reading function, and by printing the series Nα printed on the receipt in barcode format, it is possible to automatically determine which transaction the receipt placed on the slip table corresponds to. It is also possible to correct the contents of the cumulative memory, such as the departmental memory M1, in accordance with the automatic discrimination result.

[Effects of the Invention] According to the present invention, even in the case of canceling a transaction after the closing process, there is no need to restore (correct) the cumulative data through the reversal process, which simplifies the operation.
