Abstract
PURPOSE: To provide a discriminating apparatus of a simple constitution and easy fine adjustment by selectively applying the clocks of plural kinds of frequencies to a sub-counter and controlling the main counter which calculates the pass time of paper leaves.
CONSTITUTION: A sub-counter 35 which is reset by the leading end detecting signal of the paper leaves being conveyed counts the clocks of the frequency f2 selected with a switch S2, etc. at the clocks of different frequencies being outputted by a frequency converter 41 and sets an FF 40 to clear a counter 34 when a specified number K is reached. Then, while the counter 34 is counting the frequency f1 clocks by Nr thru Nr+M shots, a pulse is applied to a judgemefnt circuit 30 and if the trailing end detecting signal 2 of the paper leaves is applied during this time, the circuit 30 generates a judgement signal W only when the pass time T proportional to the length of the paper leaves satisfies the condition of the formula I. Hence, by selecting the clock frequencies being applied to the sub-counter, the specified numbers K, N4 and M are made constant and the judgement of various kinds of lengths is readily finely adjustably accomplished with the simple constitution of less number of counters.
