Description

[Detailed Description of the Invention] This invention is an electronic cash register (hereinafter referred to as ECR).
In particular, it relates to ECH, such as registering data regarding products through credit transactions.

Previously, data on products purchased by customers was sent to ECH.
Upon registration, the customer pays by cash or check, thereby completing the transaction.

However, some customers may wish to conduct margin transactions using paper forms, and some stores allow such margin transactions.

When such stores conduct margin transactions using ECR, the data regarding the products purchased by the customer is stored on the ECH.
At the same time, the total amount is posted in the ledger.

Then, in the settlement process after closing, the total amount data stored in the ECR is corrected based on the total amount of credit transactions recorded in the ledger.

As described above, when performing a credit withdrawal using the conventional ECR, there is a problem in that it requires complicated operations such as posting to a ledger and correcting the total amount data registered in the ECH.

Therefore, the main object of the present invention is to provide an ECR that allows credit transactions based on form management to be performed without error by simple key operations.

To summarize, in the case of a credit transaction using a form, the present invention specifies that the transaction is a credit transaction using a credit transaction specifying means, such as a credit key, sets a form, and inputs data regarding the product.

The input data is stored cumulatively in a first memory, for example an X register.

On the other hand, the data registered by the margin transaction up to the previous time is stored in the second memory, for example, the WP register, and when the margin transaction is identified, the data stored in the first memory and the second memory are stored. The data from previous margin transactions stored in
The data is accumulated by the PU and the accumulated data is printed on a form by a form printing printer.

Then, in the case of the next margin transaction, the data printed on the form is stored in the second memory, and then the margin transaction operation is performed.

The present invention will be described in more detail below along with embodiments shown in the drawings.

FIG. 5 is an illustrative diagram showing an example of a form with data printed by the form printing printer 70.

FIG. 6 is an illustrative view showing an example of a receipt on which data is printed by the printer 60.

FIG. 7 is a flow diagram for explaining the specific operation of one embodiment of the present invention.

Next, the specific operation of one embodiment of the present invention will be described with reference to FIGS. 1 to 7.

First, the operator switches the mode changeover switch 11 to set the REG mode.

Then, the keyboard 10 is operated according to the key operation procedure shown in FIG.

That is, the DPI key included in the department key 13 is operated.

The CPU 30 constantly determines whether or not a key input signal has been applied from the keyboard 10, and when it determines that a key input has been applied, it determines whether a key input signal has been applied from the numeric keys 12.

If the input is not from the numeric key 12, it is determined whether a key input signal is given from the department key 13 or not.

When it is determined that the department key is 13, F is entered in area 45.
It is determined whether the N flag is set and whether the FD flag is set in area 47.

If neither is set, unit price data 200 is read from the area corresponding to department 1 of department area 41,
The data is stored in the X register 48, which is an example of the first storage means.

Then, the unit price data 200 is added to the totalizer 41b of department 1.
and adds 1 to the multiplier 41a.

Then, F indicating that margin trading is in progress in area 46.
Determine whether the P flag is set.

If the FP flag is not set, the process returns to the initial state.

In addition, at this time, the receipt has DP as shown in Figure 6.
I and unit price data 200 are printed by the printer 60.

Similarly, when you operate the DP2 key, department area 41
The unit price data 250 corresponding to department 2 is read from .

This unit price data is stored in the X register 48, cumulatively added to the totalizer corresponding to department 2, and the multiplier is incremented by one.

Next, an explanation will be given of the operation when a customer desires a credit transaction using a form.

Note that the ledger is kept at the store or handed to the customer in advance, and as shown in Figure 5, the balance (1000) from the previous credit transaction and its printed line (10) are included as data. recorded.

Note that for a customer who is making a margin transaction for the first time, the balance of the previous margin loan amount is O.

When the customer desires a credit transaction, the operator inputs the previous credit loan amount balance data 1000 recorded in the ledger using the number keys 12.

In response, CPU 30 determines that there is a key input and determines that the key input is from numeric key 12.

Then, the input number data 1000 is stored in the WN work register in area 42, the FN flag in area 45 is set, and the process returns to the initial state.

Next, the operator operates the credit key 142 to specify that the transaction is a credit transaction.

In response, when the CPU 30 determines that a key manual signal has been given from the trust key 142, the CPU 30 sets an FP flag indicating that a credit transaction is in progress and an F flag indicating a request to set a form.
Determine whether any of the P flags are set.

If it is set, error processing is performed, and if it is not set, it is determined whether the FN flag is set.

If the FN flag is not set, it is considered an error, and if it is set, the data (1000) stored in the WNN work register 4 is transferred to the WP work register 43, which is an example of a second storage means, as the previous credit loan amount balance data.

Then, the FN flag is reset, and the FP flag and F
Set the D flag.

When the FD flag is set, a display indicating a request for a form is lit, for example.

When this series of operations is completed, it returns to the initial state.

Next, the operator inputs the print line 10 of the balance data recorded in the form using the number keys 12.

Then, the data is stored in the WN work register 42 and the FN flag is set.

Next, the operator sets the form on the form printing printer 70 and operates the form key 141.

At this time, the display indicating the request for a form is lit as described above, and the mistake of operating the form key 141 without forgetting to set the form can be prevented.

In response, the CPU 30 determines that the form key 141 has been operated, and determines whether the FN flag and the FD flag are set.

If both are not set, an error process is performed, and if they are set, it is determined whether the form has been set in the form printing printer 70 or not.

If it is not set, it returns to the initial state, and if it is set, the print line data "10" stored in the WN work register 42 is transferred to the WL work register 44.

Then, based on the data transferred to the WL work register 44, the form is caused to be fed by 10 lines by the form printing printer 10.

Then, as shown in FIG. 5, the credit loan amount balance data 1000 up to the previous time is printed on the form.

Furthermore, since one line has been printed, the WL work register 44 is incremented by 1.

Furthermore, the FN flag and FD flag are reset to return to the initial state.

Further, when the customer purchases a product in the department 10, the customer operates the 1) plO key included in the operator department keys 13.

Then, the CPU 30 reads out the unit price data 300 of the product 10 included in the department area 41 of the memory 40, stores it in the Add 1 cumulatively and further add 1 to the multiplier.

When the operator completes all registration processing, he operates the end key 143 to specify it.

In response, the CPU 30 determines that the end key 143 has been operated, and determines whether the FN flag and the FD flag are set.

If it is set, error processing is performed, and if it is not set, it is determined whether or not the FP flag is set.

If the FP flag is set, the data 750 cumulatively added to the X register 48 is printed on the form.

Then, by printing one line of data, the contents of the WL work register 44 are incremented by 1.

The currently registered data (750) stored in the X register 48, which is an example of the first storage means, and the previous credit loan stored in the WP work register 43, which is an example of the second storage means. The CPU 30, which is an example of a totalizing means, adds the amount balance data (iooo) and the result (
1750) is printed on the next line.

At the same time, data (14) representing the print line stored in the WL work register 44 is printed.

Then, the FP flag is reset and the X register 48
Reset to return to initial state.

After completing all operations, the operator extracts the form from the form printing printer 70 and either stores it at the store or hands it to the customer.

As described above, according to this embodiment, when a customer desires a credit transaction, the customer specifies that the transaction is a credit transaction using the credit key 142, and inputs the previous credit loan amount balance data recorded in the ledger. Then, by performing the registration process, the balance data up to the previous time and the data registered this time can be totaled and printed on the form.

Therefore, as in the past, when there is a request for margin trading, the data is registered in ECH, the data is posted to the ledger, and the data from margin trading is subtracted from the registered data after the store closes. Credit transaction processing work can be eliminated.

As described above, according to the present invention, even if a customer desires a credit transaction, the credit transaction can be reliably performed by form management with a relatively simple operation.
