Abstract

PURPOSE:To reduce electric power consumption by changing over modes so as to perform displaying as a watch automaticlly and stopping electric power to sensor parts after the use as a weighing device. CONSTITUTION:When a user removes a weighing object from a receiving tray, the outputs of a total counter group 3 are zero. This is detected by a gate part 90, and the R terminal of a timer 74 goes to an L level, by which the counting operation is started. Upon ending of the prescribed counting, a transistor 13 goes on and the controlling terminal D0 of a display selection circuit 6B goes from the H to L level, by which the display of a display device 1 is changed over to a watch display; at the same time the electric power supply to photosensors 23U, 23D, and light emitting element 22A, 22B is stopped, and the electric power consumption is reduced.
