安定化検知装置。[Scope of Claim for Utility Model Registration] (1) Signal cutoff means that holds the switching means in an open state to cut off signals to the output side as soon as the power is turned on, and a timer that starts counting a predetermined time from the time the power is turned on. a signal level determining means for determining whether or not the input signal has reached the detection level from the time when the timing operation by the clocking means is completed; and a signal level determining means for determining whether the input signal has reached the detection level from the time when the timing operation by the clocking means ends, and cutting off the signal when the signal level determining means determines that the input signal has reached the detection level 1. A signal input stabilization detection device comprising: a cutoff release means for releasing a signal cutoff caused by the means. (2) A means is additionally provided for starting the timer again when the signal level determining means determines that the signal level has reached the detection level, and driving the cutoff release means when the timer ends the timekeeping operation. The signal input stabilization detection device according to claim (1), characterized in that:
