Abstract
PURPOSE: To reduce the power consumption by providing such circuit that irradiates the light to the scale plate which is driven in accordance with the weighing action, delivers the signal corresponding to the scale through the photoelectric converting part, displaying the weight at the display unit via the arithmetic process part, and then cuts off the power supply if the weighed value becomes zero in the fixed time after removing the load respectively.
CONSTITUTION: When weighing subject 1 is put on saucer 2, the coded weighing scale appears to scale plate 3. This scale is irradiated by the lamp for reading through photoelectric converting part 4, and this read value is converted into the pulse signal. And the weight data received the rounding process is displayed at display part 7 via counter 5 and arithmetic process part 6. After removing load 1 from saucer 2, detecting part 10 detects whether plate 3 is at the zero position or not. And when plate 3 is at the zero position and this zero state is continued for a fixed time via AND gate 11 and timer part 17 which operates by the signal of the weighed value zero deciding part, switch driving circuit 15 is actuated to cut off power source 8. In this way, the power consumption can be reduced, thus enabling use of the battery.
