Then, the CPU 31 displays the bar code scanner in the state that the "register" mode is selected by the mode switch 3.
When the bar code is read by 10, the scanner process shown in FIG. 7 is executed, and when the key signal is input from the keyboard 2, the program process is executed to execute the key process shown in FIG. 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 bar code attached to the first product purchased by the customer, that is, the single product code.
When it is read in 10, the scanner process shown in FIG. 7 is started, in ST1 there is a "registration" mode, in ST2 the utility bill declaration flag F3 is "0", and in ST3 utility bill establishment flag F4 is " After confirming that each is 0 ", proceed to ST4. In ST4, since the registering flag F1 is reset to "0", the value (= 3) of the scroll start line S is set to the scroll pointer P of the scroll data memory 55, and the registering flag F1 is set to "1". And declare that one customer is being registered. Next, the product name, unit price, link department, etc. of the product corresponding to the single product code entered as ST5 are read from the store controller, and the sales points (if there is no input of the multiplier immediately before product registration, the multiplier, if there is no input of the multiplier, 1 ”) and the sales amount (unit price × point of sale) are cumulatively processed in the sales registration file 51 for each department, for example, and the sales amount is added to the totalizer memory 52. Further, as ST6, the display data for one line of the screen consisting of the number of registrations, the unit price, the number of sales, and the sales amount is edited, and this display data is displayed on the line of FIU4 corresponding to the scroll pointer P, and on the upper line of RIU5. Is also displayed. FIG. 9 shows a display example of FIU4 at this time. Further, in ST7, the print data including the number of registrations, the product name, and the sales amount is edited, and the printer 41 is driven to print out the receipt and the journal. After that, in ST8, the scroll pointer P changes the value of the last line E of the scroll (=
Since it does not match 8), there is room in the registered data display area of FIU4, so wait for the next input.

Next, when the operator reads the bar code of the second to sixth items of the customer with the bar code scanner 10,
Proceed to ST4 via ST1, ST2, ST3, and registering flag F1 is "1".
Since the scroll pointer P does not match the value (= 8) of the last line E of the scroll, the process proceeds to ST5. Then, the registration process, the display / print process are performed in the same manner as the first point, and the scroll pointer P
Will be updated. A display example of the FIU 4 at this point is shown in FIG.

Next, when the barcode of the customer's 7th item is read by the barcode scanner 10, ST1, ST2, ST3, ST4, and ST5
Then, the scroll pointer P coincides with the value (= 8) on the last line E of the scroll, and the registered data display area of FIU4 is full. Therefore, the display data on the third line of FIU4 is cleared, and from the fourth line to 8 1 for each display data up to the line
A so-called display scroll process is performed in which the lines are shifted upward by one line. After that, the registration process and the display / print process are performed in the same manner, but since the value of the scroll pointer P coincides with the value (= 8) of the scroll display line E in ST8, the scroll pointer P is not updated. FIU4 at this point
A display example of is shown in FIG.

Here, when the customer applies for the payment of the utility bill, the operator presses the utility key 29 of the keyboard 2.
Then, the key processing shown in FIG. 8 is started, the "registration" mode is set in ST10, and the utility bill establishment flag is set in ST11.
After confirming that F4 is "0", the utility charge key 29 is entered in ST12, and that the public utility charge flag F3 is "0" in ST13, the process proceeds to ST14. In ST14, the company code flag F5, the customer code flag F6 and the amount code flag F7 are reset to "0". After that, in ST15, the public utility charge flag F3 is set to "1" to declare that the public utility charge is to be registered. Then, in ST16, the screen data of the FIU 4 corresponding to the scroll start line S to the last line E is read from the screen data memory 53, saved in the screen save memory 54, and stored and held. After a while
Switch to screen display mode by setting the display mode flag F2 to "1" as ST17, edit the public utility rate declaration screen set in advance as ST18, and if this screen is displayed on FIU4, enter the next Wait for Fig. 12 shows a display example of FIU4 at this time.

Next, the operator is the company code (JAN code 8 digits and the leading “7”) printed as a bar code on the utility bill, customer code (JAN code 13 digits and the leading “7”), and the amount code. (13 digits of JAN code and “8” at the beginning) is scanned once by each barcode scanner 10. For example, first, when the company code is read, the scanner process of FIG. 7 is started, in ST1 the mode is "registration", in ST2 the public utility charge flag F3 is set to "1", ST19 The company code was read at
After confirming that the company code flag F5 is reset to "0" in ST20, the process proceeds to ST21. In ST21, 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 from the barcode scanner 10 is stored in the company code data area D1 of the utility fee data memory 56,
Edit this company code data to display data, FIU4
The company code is displayed on the line (6th line in this embodiment) which is set in advance as the company code display line as the screen display mode. Then, at ST22, the company code flag F
5, The state of the customer code flag F6 and the amount code flag F7 is checked, and since only the company code flag F5 is still set to "1", the next input is awaited.

Next, when the operator reads the amount code with the bar code scanner 10, the scanner process of FIG. 7 is restarted, the ST1 is in "registration" mode, and the flag F3 for declaring public utility charges is set to "1" in ST2. After confirming that they are set, the amount code is read in S23, and the amount code flag F7 is reset to "0" in ST24, the process proceeds to ST25. In ST25, the amount code flag F7 is set to "1" to declare that the amount code has been read. And 13 read from the barcode scanner 10
The digit scan data is stored in the amount code data area D3 of the utility fee data memory 56, and this amount code data is edited into display data, which is set in advance in the amount code display line as the screen display mode of FIU4. The amount code is displayed on the (8th line in this embodiment). Then, at ST22, only the company code flag F5 and the amount code flag F7 are still set to "1", so the next input is awaited.

Next, when the operator reads the customer code with the bar code scanner 10, the scanner process of FIG. 7 is restarted, and in ST1, the "registration" mode is set. In ST2, the public utility charge flag F3 is set to "1". After confirming that it is set, the customer code is read in ST26, and the customer code flag F6 is reset to "0" in ST27,
Continue to ST28. In ST28, 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 bar code scanner 10 is stored in the customer code data area D2 of the utility bill data memory 56, and the customer code data is edited into display data, which is previously set as the screen display mode of the FIU4. The customer code is displayed on the line set in the customer code display line (7th line in this embodiment). After that, ST
At 22, the company code flag F5, the customer code flag F6, and the amount code flag F7 are all set to "1", so it is confirmed that all the data necessary for the registration of public utility charges has been entered. The flag under declaration F3 is reset to "0", the flag under public utility charge F4 is set to "1", and the process proceeds to ST30. ST30 recognizes the amount of utility bill shown by the data in the amount code data area D3, and if this amount is 30,000 yen or more, 200 yen stamp is required, so edit the display data for stamp fee billing. And this display data
As the screen display mode of FIU4, it is displayed on the line (the ninth line in this embodiment) which is set in advance as the stamp billing data display line, and is displayed on the upper line of RIU5. Then, as ST31, the message display on the 4th and 5th lines in FIU4 is deleted. Also, as ST32, the amount of the utility charge indicated in the amount code is added to the totalizer memory 52, and as ST33, the amount of the utility charge is set in advance in the amount data display line as the screen display mode of the FIU4. In the embodiment, it is displayed on the 10th line) and the lower line of RIU5. Fig. 13 shows a display example of FIU4 at this time. In addition, the printer 41 is driven to print out the amount of the utility bill on a receipt and a journal. After that, this public utility fee registration is edited as one registration to display data for one line on the screen, and the next input is waited.

Here, the operator performs a scanner operation or a key operation as needed. Now, when the operator reads the bar code of the customer's 8th item, the scanner process shown in FIG. 7 is started, the ST1 is in the "registration" mode, and the flag F3 for declaring public utility charges is set in ST2. After confirming that the utility charge has been reset to "0", the utility charge flag F4 is set to "1" in ST3 and the utility charge was registered immediately before, so the process proceeds to ST35. In ST35, the display mode flag F2 is reset to "0" and the FIU4 is returned to the scroll display mode. Then, in ST36, the screen data retained in the screen save memory 54 is restored to the screen data memory 53, and the contents of the screen data memory 53 are returned to the contents just before the public utility key 29 was pressed. At this time, since the scroll pointer P has not been updated, it coincides with the state immediately before the public utility key 29 is pressed. Next, the utility price data edited as ST37 is converted to FIU4.
Is displayed on a line corresponding to the value of the scroll pointer P in the above, but if the scroll pointer P already matches the value (= 8) of the scroll end line E, the display scroll processing is performed before the pointer line. To display. After that, as ST38, the public utility rate flag F4 is set to "0".
After resetting to ST9, the process proceeds from ST4 to ST9, where display scroll processing is performed as necessary, registration processing and display print processing are performed, and the next input is awaited. Fig. 14 shows a display example of the FIU 4 at this time.

If there is a key operation instead of a scanner operation after registration of public utility charges, the key processing shown in Fig. 8 is started, and after confirming that the mode is "registration" in ST10, the public utility charge flag is confirmed in ST11. Since F4 is set to "1", ST
The program proceeds to 35 'and executes the same processing as ST35 to ST39 described above.

Finally, the operator selects the deposit / cash total key 24 on the keyboard 2.
When is pressed to instruct the customer to close the registration, the key processing shown in Fig. 8 is started. In ST40, the deposit / cash total key 24 is input, and in ST41 the registration flag F1 is set to "1". After confirming that each is confirmed, a change calculation is performed to reduce the total amount in the totalizer memory 52 from the deposit amount from the customer,
The deposit amount is on the 11th line of FIU4, and the calculated change is FIU4
On the 12th line and the lower line of RIU5. Also,
The printer 41 is driven to print out the total amount, deposit amount and change on a receipt and a journal, the receipt is issued from the receipt issuing port 7, and the drawer 11 is opened. One example of receipt 60 issued at this time
Shown in Figure 15. After that, 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 apparent from the description of this embodiment that operates as described above, in the POS terminal of this embodiment, registration of utility bills using the screen display mode is instructed during registration of products using the scroll display mode. Then, the display screen data in the scroll display mode is temporarily saved and stored in the screen save memory 54, and the screen display mode is switched to. After that, when the registration of the utility bill is completed and the user returns to the product registration or performs a necessary key operation, the display screen data saved in the screen save memory 54 returns to the scroll display mode, and is displayed again on the FIU4. To be done.

Therefore, since 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, the normal product registration using the scroll display mode and the screen display mode can be performed. You can mix and process the registration of utility bills to be used. As a result, the merchandise registration and utility bill registration, which conventionally had to be handled as separate transactions, can be handled as one transaction, so once for customers who pay the utility bill at the beginning of shopping. Tightening operation is required, and operability can be improved and work efficiency can be improved. Further, since only one receipt is issued to such a customer, the customer will also be impressed.

In the above-mentioned embodiment, the registration of the utility bill is illustrated as an example of using the screen display mode, but it goes without saying that the invention is not limited to this. Further, in the above-described embodiment, by pressing the utility charge key 29, the scroll display mode is automatically switched to the screen display mode, and after the registration of the utility charge is completed, a scanner operation or other key operation is performed to enter the scroll display mode. Although the case of automatically returning is shown, a switching means such as a DIP switch may be separately provided, and the scroll display mode and the screen display mode may be switched by this switching means. Further, although the POS terminal is exemplified in the above embodiment, the present invention can be applied to a single electronic cash register. In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, the scroll display mode and the screen display mode can be easily changed within one transaction, the operability can be improved, and the work efficiency of registration work can be improved. It is possible to provide an electronic cash register that can improve the cost.
