Abstract

PURPOSE: To facilitate battery drive by reducing electric power consumption by providing a means of cutting off electric power supply to each part except an arithmetic processing part when a metered-value-zero state continues for a prescribed time.
CONSTITUTION: When object to be method 1 on saucer 2 is removed, there are no weight data of counter 5 and arithmetic processing part 6. As timer part 12 stays in a timer-set state continuously for a prescribed time, timer part 12 is placed in a time-up state with the zero detection output of metered-value-zero decision part 11 that has decided the weight data. Then, arithmetic processing part 6 having received the time-up output releases switch driving circuit 9 from an activated state to open switches 13 and 15, so that electric power supply to photoelectric conversion part 4, counter 5 and display part 7 will be stopped. If metering operation is started before the time is up, timer part 12 is immediately reset to put the electric power source to work. Thus, a waste of electric power is prevented and battery drive can be facilitated.
