Abstract
PURPOSE: To avoid the disagreement between the display of the set dial and the actual count number by carrying out the counting at both the rise and fall of the output pulse sent from the detector.
CONSTITUTION: Pulse M for the addition/subtraction decision purpose is delivered via both circuits of AND and OR and thus delayed slightly in comparison with the counting output pulse F delivered via only the OR circuit. Thus pulse M is still at the "L" level at the rise point of output F to give the addition instead of the subtraction which should be originally given. To avoid this, delay circuit 20 comprising inverters 21 and 22, resistors 23 and 24 plus capacitor 25 is provided between OR circuit 8 to give a logic process to the output pulse of the detector and addition/subtraction counter circuit 13. As a result, pulse F is delayed by time t at the subtraction time and then supplied to circuit 13 sufficiently after the rise of pulse M. In such way, an assured counting is secured at both the rise and fall of the input pulse, thus avoiding the disagreement of the counting number.
