Abstract
An apparatus for measuring a weight including a tuning fork vibrator to produce an oscillation signal having a frequency determined in accordance with a weight applied to the vibrator, a circuit for detecting an abnormal increase in an amplitude of the oscillation signal due to disturbing vibration to produce an abnormal signal, a frequency counter for counting the number of waves of the oscillation signal except for a period during which the abnormal signal is generated and a data processor for resetting the frequency counter each time the frequency counter has counted waves of the oscillation signal for a predetermined period and calculating a measured weight from a count value of the frequency counter.
