Also, the above-mentioned amount of money and the product number are displayed on the product number display portion 11. Next, the above amount is added to the sales amount 30 in the sales data area 31 of the corresponding product number in the RAM 18, and the food ticket issuance and registration work is completed.

When FLAG1 ≠ 1 in P3, the process proceeds to P5, and when FLAG2 = 1, it is determined that the middle key has been pressed, and the (middle) character data in the character area 32 is additionally stored in the print product name buffer 35, and The amount of change 30 corresponding to the size of the amount of change area 33 is added to the unit price to obtain the amount of sale, which is stored in the print amount buffer 36. After resetting FLAG2 to 0, the process goes to P4. When FLAG2 ≠ 1 in P5, the process proceeds to P6, and it is checked whether FLAG3 is 1, and when FLAG3 = 1, it is determined that the half rice is pressed, and the (half rice) character data is sent to the print product name buffer 35. In addition to the additional storage, the sales amount obtained by adding the change amount (-20) corresponding to the half rice to the unit price is stored in the print amount buffer 36. Then, after resetting FLAG3 to 0, the process proceeds to P4. When FLAG3 ≠ 0 in P6, it is determined that the quantity change key 8 has not been pressed, and the unit price previously read from the sales data area 31 is stored as it is in the print amount buffer 36 as the sales amount, and then the process proceeds to P4.
