When this key input is performed, the number entered in the number buffer 31 is stored as an amount in the display buffer 33 and the print buffer 34, and the contents of the display buffer 33 are output to the display 17. Subsequently, the amount is cumulatively registered as product sales data in the departmental totalizer 36, divided by department according to the department code. This cumulative total registration is performed by reading out the corresponding cumulative amount from the departmental totalizer 36, adding the inputted amount to that amount, storing the result again in the corresponding area, and adding 1 to the number of sales points. Subsequently, the input amount is added to the customer total buffer 35. Finally, the product code and amount stored in the print buffer 34 are output to the printer drive circuit 14, and both printers 12.1
Step 3 prints out the receipt and journal.

FIG. 7 shows the key processing of the subtotal key 185, and this key operation becomes valid if "registration mode" is designated with the mode switch 11 and registration is in progress. When this key power is present, the contents of the customer total buffer 35 are output to the display 17 via the display buffer 33.

FIG. 8 shows the key processing of the deposit/cash total key 186. When "registration mode" is specified with the mode switch 11 and there is a manual input to this key during registration, there is a manual input using the numeric key 181 just before that. If there is a number, compare the number and the total amount, and if the number is equal but larger, change is obtained by (number value - total), and the change is sent via the display buffer 33. Output to display 17. At this time, if the set value is smaller than the total, an error is generated. In addition, the total amount, deposited amount, and change are sequentially output to the printer drive circuit 14 via the print buffer 34, and both printers 12
．． 13 to print out the receipt and journal. Then, the receipt printer 12 is caused to issue a receipt. If no number has been entered using the number key 181 immediately before, the total amount in the customer total buffer 35 is outputted to the display 17 via the display buffer 33. Further, the total amount is output to the printer drive circuit 14 via the print buffer 34, and both printers 12 and 13 print out the receipt and journal. And receipt printer 1
2 to issue a receipt.

After the receipt is issued, the total amount is registered in the cash totalizer of the transaction totalizer 37, the customer total buffer 35 is cleared, and a drawer opening signal is output to the drawer opening device 16.

FIG. 9 shows the key processing of the chip key 187, and this key operation becomes valid if the "registration mode" is designated with the mode switch 11 and change is being displayed. Immediately before this key, input the tip amount using the number key 181.The input value is compared with the change amount, and if the input value is equal to or smaller than the change amount, it is considered valid, and (change - input value ) and the result is displayed on the display 1 via the display buffer 33.
Output to 7. In this case, if the entered value is larger than the amount of change, an error occurs. Subsequently, the result of the calculation (change - number placed) and the input tip amount are outputted to the printer drive circuit 14 via the print buffer 34, and printed out on a journal by the journal printer 13.

Also, place the number key 18 just before this key. If there is no manual input, zero data will be output to the display 17 via the display buffer 33, and the displayed change will be output as the full tip amount to the printer drive circuit 14 via the print buffer 34, which will print the journal printer. 13 causes the journal to print out the output.

Finally, the chip amount is cumulatively registered in the amount section of the chip totalizer 38, and the number of times section is incremented by 1.

In the present invention having such a configuration, the mode switch 1
By specifying the "registration mode" in step 1, product sales data can be registered. That is, by entering the department code with the number key 181 and operating the department key 183, entering the amount of the product with the number key 181 and operating the amount key 184, the product sales data can be displayed as the total by department. The total is registered in the customer total buffer 36 and stored in the customer total buffer 35. Further, the product sales data is displayed on the display 17 via the display buffer 33, and is printed out on receipts and journals via the print buffer 34 by the printers 12 and 13. By repeating this key operation, department registration is performed for each customer's product.

When the subtotal key 185 is operated subsequent to this key operation, the customer's total amount stored in the customer total buffer 35 is read out and displayed on the display 17 via the display buffer 33.

In this state, if you enter the deposit amount from the customer using the number keys 18 and operate the deposit/cash key 186, change will be calculated by (f'fi amount - total amount), and the change will be displayed in the display buffer. It is displayed on the display 17 via 33. Further, the total amount, deposited amount, and change are sequentially printed out on a receipt and a journal by the printer 12.13 via the print buffer 34, and the receipt is issued.

In this state, when a customer offers a tip, the amount is entered using the number keys 181 and tip key 1 is entered.
Operate 87. The calculation (change - tip amount) is then performed, and the result is displayed on the display 17 as change to be returned to the customer.

Further, the tip amount and (change - tip amount) are each printed out on a journal by the journal printer 13. Further, the chip amount is accumulated in the amount section of the chip totalizer 38, and the number section is incremented by 1.

Also, when the customer offers to provide the entire amount of change as a tip, the tip key 1 is pressed without operating the number key 181.
87 alone. By operating this key, the entire amount of change displayed is printed on the journal as a tip amount and is accumulated in the tip totalizer 38. Of course, the display on the display 17 changes to zero.

When a customer provides a tip while the change is being displayed in this manner, the amount and number of tips can be accumulated in the tip totalizer 38 by key operation. Further, since the change to be finally returned to the customer is displayed on the display 17, the change can be returned to the customer according to the display.

In the above embodiment, the tip amount is printed out on the journal, but the tip amount is not necessarily limited to this, and in the case of a type that does not cut the receipt, it may be printed out on the receipt.

[Effects of the Invention] As detailed above, according to the present invention, when a customer provides a tip, the amount to be returned to the customer can be displayed, and the tip amount provided by the customer can be registered and managed. It can provide electronic cash registers.
