Electronic weighing apparatus

An electronic weighing apparatus, comprising:

• means responsive to the weight of an article being weighed for causing a displacement associated with the weight of said article, means responsive to the displacement of said displacement means for providing an electrical signal representing the displacement of said displacement means and thus the weight of said article, means operatively coupled to said electrical signal providing means for storing said weight associated electrical signal, means responsive to said electrical signal storing means for displaying the weight of said article, vibration detecting means operatively coupled to said electrical signal providing means for detecting an undesired vibration of said displacement means, means operatively coupled to said storing means and to said vibration detecting means and responsive to the output from said vibration detecting means for preventing said weight representing electrical signal from being stored in said storing means for a predetermined time period, said electrical signal providing means comprising pulse generating means responsive to the displacement of said displacement means for generating a pulse train having a number of pulses representative of the displacement of said displacement means, counter means operatively coupled to said pulse generating means for counting the number of pulses in said pulse train, said displacement means being adapted to cause displacement in a first direction in response to a relative increase in the weight of the article and to cause displacement in a second direction in response to a relative decrease in the weight of the article, said pulse generating means being adapted to generate a first pulse train responsive to the displacement of said displacement means in said first direction and to generate a second pulse train responsive to the displacement of said displacement means in the second direction, said vibration detecting means comprising signal output means responsive to sequential generation of said first pulse train and to said second pulse train in the stated order for providing a vibration representing output for a predetermined time period, said signal output means comprising storing means assuming a first state in response to said first pulse train and assuming a second state in response to said second pulse train, delay means coupled to said storing means for delaying one state output of said storing means for a predetermined time period, and means coupled to said delay means and the other output of said storing means for providing a logical product of the output from said delay means and the other output of said storing means.
