Abstract

PURPOSE: To discriminate the state of input waveform generating source depending on the first and second states, and elongate the discriminating time, by forming the first and second states depending on whether an input waveform exceeding the reference pulse reaches within the specified period or not.
CONSTITUTION: For instance, the sound wave at the time of blanking out by the press is inputted into a comparator 1 as an input waveform, and is compared with the reference level. The part of waveform exceeding the reference level becomes a pulse, which is outputted from the comparator 1. As a result, a pulse of micro width is outputted from a monostable multivibrator 5. This pulse is inputted into a pulse annihilation detecting circuit 6. If this pulse is inputted within the set period, level 1 is outputted, and if it is not inputted within the set period, level 0 is outputted. A counter 2 counts the outputs from the pulse annihilation detecting circuit 6 for a specified period. When this count value is beyond the reference count value, a discriminating circuit 3 judges that a failure has occurred in the blanking- out press, motor, or the like.
