する超音波物体検知器。 An ultrasonic transducer is used for transmitting and receiving waves, and an object is detected by transmitting ultrasonic pulses from this ultrasonic transducer and receiving reflected waves from the object.
In an ultrasonic object detector that changes the timing at which the reception gate opens according to the expansion and contraction of the reverberant vibration of the ultrasonic transducer, the reverberant vibration causes An ultrasonic object detector characterized in that the ultrasonic object detector is equipped with a notification means for notifying that an object at the shortest detection distance cannot be detected because the reception gate is not opened when the reception gate is not opened.
