Screen display devices used in such electronic cash registers usually have a scroll display mode or a screen display mode, and depending on the model, the scroll display mode is selected for operations in registration mode, and the screen display mode is selected for operations in setting mode. The display mode was fixed for each task, such as a display mode being selected.

In addition, recently, models have been developed that can selectively use either scroll display mode or screen display mode for each transaction, depending on the transactions handled in registration mode operations. For example, recently convenience stores are accepting payments for utility charges such as electricity and gas, but some POS terminals for convenience stores that can process special registrations such as payment of utility charges require scroll display mode to be selected for product registration. However, some special registrations allow you to select a screen display mode.

[Problems to be Solved by the Invention] However, even in the above-mentioned electronic cash register in which product registration is performed in scroll display mode and special registration is performed in screen display mode, the display mode can only be changed for one transaction. Therefore, for customers who pay utility bills at the beginning of shopping, store clerks must register the product, perform the closing operation, and then register the utility bill payment. The store staff had to calculate the amount by adding the total amount and utility charges and collect it from the customer.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide an electronic cash register that can easily change between scroll display mode and screen display mode during transactions, improve operability, and increase work efficiency of registration operations. It is.

[Means and effects for solving the problem] The present invention includes a screen display device that can select between a scroll display mode and a screen display mode, and when a sales product is registered via an input device, sales data of the product is displayed. In an electronic cash register that accumulates the amount in the memory and displays it in one display mode on the screen display device, and when the closing key is operated, a receipt with the sales data and its total printed is issued to complete one transaction. , a screen save memory is provided, and when a display mode change is commanded before the closing key is operated, the currently displayed screen data is saved and held in the screen save memory, and the screen data held in the screen save memory is The screen data is re-displayed on the screen display device in response to a command to return to the display mode before the closing key is pressed.By doing this, the time between the product registration and the closing key being pressed is made to be displayed again on the screen display device. Scroll display mode and screen display mode can be used alternately within a transaction.

is set in advance.

Therefore, the CPU 31 is activated by the mode switch 3.
When the barcode scanner 10 reads a barcode while the "registration" mode is selected, the scanner process shown in FIG. 7 is executed, and when a key signal is input from the keyboard 2, the key process shown in FIG. 8 is executed. The program is configured to run. The operation in the "registration" mode of this embodiment will be described below with reference to FIGS. 7 and 8.

First, the operator scans the barcode attached to the first product purchased by the customer, that is, the single item code, using the barcode scanner 1.
If it is read as 0, it starts the scanner process in Figure 7, and confirms that the STI is in the "registration" mode, that the utility charge declaration flag F3 is "0" in Sr1, and that the ST3 utility charge establishment flag F4 is " Check that each is 0" and set Sr
Go to 1. In Sr1, since the registration flag F1 is reset to 0, the value of the scroll start line S (-3) is set to the scroll pointer P of the scroll data memory 55, and the registration flag F1 is set to 1'. to declare that one customer is being registered. Next, the product name, unit price, and
Read the link department, etc. from the store controller, and the number of sales items (if a multiplier is input just before product registration, the multiplier).

If no multiplier is input, the sales amount (unit price x number of items sold) is accumulated in the sales registration file 51, for example, by department, and the sales amount is added to the totalizer memory 52. Also, as ST6, edit one line of display data on the screen consisting of the number of registrations, unit price, number of items sold, and sales amount, and move this display data to the F corresponding to the scroll pointer P.
It is displayed in the row of IU4 and also in the upper row of RIU5. A display example of the FIU 4 at this point is shown in FIG. Furthermore, one product name has been registered as ST7.

The print data consisting of the sales amount is edited, and the printer 41 is driven to print it out on the receipt and journal. Thereafter, in ST8, the scroll pointer P does not match the value (-8) of the last row of scrolling E, and since there is some room in the registered data display area of the FIU 4, the next input is waited.

Next, when the operator or the customer reads the barcodes of the second to sixth products with the barcode scanner 10,
STI, ST2. Proceeds to ST4 via ST3, and since the registration flag F1 is set to "1", proceeds to ST9, where the scroll pointer P moves to the value of the last scroll line E (
-8) is not met, proceed to ST5. However,
Registration processing 1 display/printing processing is performed in the same way as the 1-point exit,
Scroll pointer P is updated. Incidentally, a display example of the FIU 4 at this point is shown in FIG.

Next, when the barcode of the customer's 7-point product is read using the barcode scanner 10, the STI is detected.

ST2. ST3. Proceeding to ST5 via ST4, the scroll pointer P matches the value (-8) of the last scroll line E, and the registered data display area of FIU4 is full, so the display data of the third line of FIU4 is cleared, A so-called display scroll process is performed in which each display data from the 4th line to the 8th line is shifted upward one line at a time. After that, registration processing 1 display/print processing is performed in the same manner, but
In ST8, since the value of the scroll pointer P matches the value (-8) of the scroll display line E, the scroll pointer P is not updated. Incidentally, a display example of the FIU 4 at this point is shown in FIG.

Here, if the customer applies for payment of utility charges, the operator presses the utility charge key 29 on the keyboard 2.

Then, the key processing shown in Fig. 8 is started, and the "registration" mode is confirmed at 5TIO, the utility charge status flag F4 is "0" at 5TII, and the utility charge key 29 is input at 5T12. In ST13, it is confirmed that the utility charge declaration flag F3 is "O", and the process proceeds to ST1.4. In 5TI4, the company code flag F5. Customer code flag F6 and amount code flag F
7 to "0". After that, 5TL5
The public charge declaration flag F3 is set to "1" to declare that the public charge will be registered. And 5TL
As G, the screen data of the FIU 4 corresponding to the scroll start line S to the final line E is read out from the screen cover memory 53, and is saved as it is to the screen save memory 54 and stored and held there. After that, the display mode flag F2 is set as 5T17.
is set to "1" to switch to the screen display mode, edit the utility charge declaration screen preset as 5TI8, display this screen on the FIU 4, and then wait for the next human power. A display example of the FIU 4 at this point is shown in FIG.

Next, the operator enters the company code (JAN code - 8 digits, starting with r7J) and customer code (JAN code 13) printed as a barcode on the utility bill payment notice.
The first digit is r7J), the amount code (JAN code 13)
The first digit is "8") and barcode scanner 10.
Read each one at a time. For example, first, when the company code is read, the scanner process shown in Figure 7 is started, and the STI shows that it is in "registration" mode, and the utility charge declaration flag F3 is set in ST2.
After confirming that F5 is set to "1", that the company code is read at 5T19, and that the company code flag F5 is reset to "0" at 5T20, the process advances to 5T21.

At 5T21, the company code flag F5 is set to "1" to declare that the company code has been read. Then, the 8-digit scan data read by the barcode scanner 1o is stored in the company code data area D1 of the utility data memory 56, and this company code data is edited into display data and set in advance as the screen display mode of the FIU 4. The company code is displayed on the line set as the company code display line (line 6 in this embodiment). After that, at 5T22, the company code flag F5. Customer code flag F6. The state of the amount code flag F7 is checked, and since the company code flag F5L has not yet been set to "1", the next input is awaited.

Next, when the operator reads the amount code with the barcode scanner 10, the scanner process shown in FIG. Must be set, 5T2
After confirming that the amount code has been read at step 3 and that the amount code flag F7 has been reset to "O" at 5T24, the process advances to 5T25. At 5T25, the amount code flag F7 is changed to "]" to declare that the amount code has been read. Then, the 13-digit scan data read from the barcode scanner 10 is transferred to the amount code data area D of the utility charge data memory 56.
3, edit this amount code data into display data, and display the amount code in the line that is set in advance as the amount code display line (line 8 in this example) as the screen display mode of the FIU 4. . After that, at 5T22, only the company code flag F5 and the amount code flag F7 are still set to "1", so the next manual effort is awaited.

Next, when the operator reads the customer code with the barcode scanner 10, the scanner process shown in FIG. Must be set, 5T2
After confirming that the customer code has been read at G and that the customer code flag F6 has been reset to "0" at 5T27, the process advances to ST2g. At ST2g, the customer code flag F6 is set to "1" to declare that the customer code has been read. Then, the 13-digit scan data read from the barcode scanner 10 is transferred to the customer code data area D of the utility data memory 56.
2, edit this customer code data into display data, and display the customer code in the line that has been set in advance as the customer code display line (line 7 in this example) as the screen display mode of the FIU 4. . After that, at 5T22, the company code flag F5. Since the customer code flag F6゜ and amount code flag F7 were both set to "1", it is recognized that all the data necessary for registering the utility charge has been input, and the utility charge declaration flag F3 is set to "0" at 5T29.
" and set the utility charge status flag F4 to "1", and proceed to 5T30. At 5T30, the amount of the utility charge indicated by the data in the amount code data area D3 is recognized, and this amount is 30,000 yen. 2 if it is more than yen
00 yen stamp is required, so edit the display data for stamp fee request, and use this display data as the screen display mode of FIU 4 in the line set in advance as the stamp fee request data display line (in this example, 9 lines). It is displayed in the upper row of the RIU 5. Thereafter, as 5T31, the message display at the beginning of the 4th line and the beginning of the 5th line in the FIU 4 is erased.

Further, as 5T32, the amount of the utility fee indicated by the amount code is added to the totalizer memory 52, and as 5T33, this amount of the utility fee is added to the screen display mode of the FIU 4 in the line (main) set in advance in the amount data display line. In the embodiment, it is displayed on the 10th line) and also on the lower line of the RIU 5. The first example of the display of FIU4 at this point is
Shown in Figure 3. Further, the printer 41 is driven to print out the amount of this utility charge on a receipt and a journal.

After that, screen 1 will be displayed with this utility charge registration as one registration.
Edits the display data for one line and waits for the next input.

Here, the operator performs scanner operation or key operation as necessary. Now, when the operator reads the barcode of the customer's 8th product, it starts the scanner process shown in Figure 7 and confirms that it is in the "registration" mode in the STI.
After confirming in step 1 that the utility charge reticence flag F3 is reset to 0'', in ST3 the utility charge completion flag F4 is set to 1, indicating that the utility charge has been registered just before. Therefore, proceed to 5T35. In 5T35, the display mode flag F2 is reset to "0" and the FIU4
Returns to scroll display mode. Then, the screen data held in the screen save memory 54 as 5T3G is restored to the screen data memory 53, and the screen data memory 53
The contents are returned to the contents immediately before the utility charge key 29 was pressed. At this time, since the scroll pointer P has not been updated either, it matches the state immediately before the utility charge key 29 was pressed. next,
5T37, the edited utility charge data is displayed on the line corresponding to the value of the scroll pointer P in FIU4, but here, if the scroll pointer P already matches the value (-8) of the last scroll line E, performs display scroll processing and then displays it on the pointer line.

After that, when the utility charge completion flag F4 is reset to "0" as 5T311, proceed to ST9 via ST4, perform display scroll processing as necessary, perform registration processing 1 display printing processing, and enter the next input. wait. A display example of the FIU 4 at this point is shown in FIG.

Furthermore, if there is a key operation instead of a scanner operation after the registration of utility charges is completed, the key processing shown in Fig. 8 is started, and after confirming that it is in the "registration" mode with 5TIO, ST1.1
Since the utility charge status flag F4 is set to "," proceed to 5T35' and perform the above-mentioned 5T35 to 5T.
39 is executed.

Finally, the operator presses the deposit/cash key 24 on the keyboard 2.
When the customer is pressed to instruct the customer to complete the registration process, the key processing shown in FIG. 8 is started, and at 5T40, it is confirmed that the r11/current total key 24 is input, and at 5T41, the registration flag F1 is set to "1".
After confirming that the total amount in the totalizer memory 52 is set from the deposited amount from the customer, a change calculation is performed to subtract the total amount in the totalizer memory 52, and the deposited amount is added to the 11th line of FIU 4, and the calculated change is FIU4 line 12 and RIU5
Display each in the bottom row of . Further, the printer 41 is driven to print out the total amount, deposited amount, and change on a receipt and a journal, to issue a receipt from the receipt issuing lower, and to open the drawer 11. FIG. 15 shows an example of Resitro 0 issued at this time. Thereafter, the totalizer memory 52 and the utility charge data memory 56 are cleared, the registration flag F1 is reset to "0", and one transaction is completed.

As is clear from the description of this embodiment that operates as described above, in the POS terminal of this embodiment, registration of utility charges using screen display mode is instructed during product registration using scroll display mode. Then, the display screen data in the scroll display mode is temporarily saved in the screen save memory 54 and stored therein, and the screen display mode is switched. After that, when the registration of utility charges is completed and the return is made to product registration or the necessary key operation is performed, the display screen take that was saved in the screen save memory 54 is returned to the scroll display mode and is redisplayed on the FIU 4. be done.

Therefore, the FIU 4 of the screen display device 6 can be used by switching between the scroll display mode and the screen display mode during one transaction. Can be used in conjunction with public interest registration and processing. As a result, product registration and utility charge registration, which previously had to be processed as separate transactions, can now be processed as a single transaction, so customers who pay utility charges before shopping can be processed once. Only a tightening operation is required, which improves operability and increases work efficiency. In addition, since only one receipt is issued to such a customer, it leaves a good impression on the customer.

In the above embodiment, registration of public charges was exemplified as an example of using the screen display mode, but it goes without saying that the method is not limited to this.

Further, in the above embodiment, the scroll display mode is automatically switched to the screen display mode by pressing the utility charge key 29, and the scroll display mode is automatically switched from the scroll display mode to the screen display mode by pressing the utility charge key 29, and by performing the scanner operation or other key operation after the registration of the utility charge is completed. Although the case in which the mode is automatically returned to is shown, a switching means such as a dip switch or the like may be provided separately, and this switching means may be used to switch between the scroll display mode and the screen display mode. Furthermore, although the above embodiments have exemplified a POS terminal, the present invention can also be applied to a single electronic cash register.

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, it is possible to easily change the scroll display mode and the screen display mode within one transaction, which improves operability and improves the work efficiency of registration work. We can provide an electronic cash register that can increase the
