Abstract

PURPOSE: To smooth and quicken change services, by calculating the amount of change by subtracting a unit price from the amount of receipt through the operation of a unit-price setting key after the amount of receipt is input.
CONSTITUTION: The amount of receipt is registered by operating ten-digit numeric keys 8 and then unit-price setting key 14 is operated to register a unit price. Next, CPU2 subtracts the unit price from the amount of receipt to calculate the amount of change, which is displayed on display part 4. On the basis of the amount of change, the kinds and number of coins for the change are calculated and motor driving signal MO and solenoid driving signal SO are sent to mechanism part 5 so as to discharge change coins, so that while the number of times of keying is small, the possibility that an operation error is made will be eliminated.
