Abstract

PURPOSE:To avoid an erroneous inversion with a simple constitution, by using the JK-type flip-flop FF. CONSTITUTION:When the switch 4 is closed with a correction given to the time, the correction start signal of active low is generated from the switch circuit 5 to clear and start the counter circuit 3 and the switch box driving waveform circuit 6 each. At the same time, the correction start signal sent from the circuit 5 is applied to the terminal JK of the JK-type FF200 forming the phase inverting circuit 7 to hold the FF200. Accordingly, the beard pulse generated from the circuit 6 does not affect the circuit 7 when the switch 4 is closed. As a result, the erroneous inversion of the switch box 9, which is caused by recognizing mistakenly the beard pulse as the driving signal, can be avoided assuredly with a simple constitution.
