ABSTRACT:
In a mechanical sector scanner, a first bevel gear is mounted on the end of an output shaft of a motor, and an ultrasonic transducer is rotatably supported for rotating about a scanning axis transverse to the output shaft. A second bevel gear engaging the first bevel gear is mounted on the back surface of the transducer. The output shaft oscillates about an output axis. Oscillations of the output shaft are coupled to the transducer by the bevel gears. The second gear has a plurality of teeth arranged in an arc less than completely around the scanning axis, and the second gear is so disposed that the back surface of the transducer is nearer to the scanning axis than the teeth.
