发明名称 FALE SAFE COUNTER
摘要 PURPOSE:To simplify the circuit constitution and to make light and small in size, by counting the first and second counted signals and performing program operation for the agreement and disagreement of the both count values. CONSTITUTION:The separation circuit 1 receives the counted signal and separates it into counted signals S21 and S22. They are fed to the counters 7 and 8 respectively to discriminate the agreement and disagreement of the both count values. As a result, if the both count values are in agreement, the output value is made to ''1'' and to ''0'' when disagreement. In this case, when the signal S21 is taken place, the program advancing the counter 7 starts operation to advance the counter 7, and when the signal S22 is inputted, the program starts operation to advance the counter 8. Succeedingly, the count value of the counters 7 and 8 is compared and the agreement and the disagreement of the both count values are in program operation. Thus, the circuit constitution is made simpler to make light the unit in weight and small in the size.
