PROBLEM TO BE SOLVED: To prevent a pulse caused by a malfunction from being outputted to a circuit of a subsequent stage without performing ground reinforcement or noise cutoff measures in a pulse generator circuit. SOLUTION: A monostable multivibrator circuit 3 outputs a signal of a prescribed pulse width at needed timing, and a differentiating circuit 4 inputs an output signal of the monostable multivibrator circuit 3, differentiates the output signal and outputs the differentiated output signal. A signal outputted from the differentiating circuit 4 is inputted to a monostable multivibrator circuit 7, and when noise occurs, the multivibrator circuit 7 operates. An AND circuit 8 ANDs signals outputted from the monostable multivibrator circuits 3 and 7 and outputs the results. |
