CONSTITUTION: Since a power source switching signal is not outputted from a CPU10 when an automatic transaction device, etc. is not used, switch circuits 14 and 15 are turned on. Thus a power source voltage from a solar battery 4 is impressed to a CPU10, ROM11 and RAM12. When a balance display indicating switch 15 is depressed in the state, the CPU10 reads out a balance from a data memory 12 and displays it with a display part 3. Then a paying-in transaction display indicating switch 6 is depressed. The CPU10 reads out the latest paying-in transaction data, that is, paying-in transaction data and its sum, and displays them with the display part 3.
