ABSTRACT:
An ultrasonic scanner, comprising a holder for supporting the ultrasonic probe, said holder being rotatably pivoted by a pivoting shaft, a rotating shaft whose axis is perpendicular to the axis of the pivoting shaft pivoting the holder, and a motion-converting mechanism for converting the rotation of the rotating shaft to a rotatingly reciprocating motion of the ultrasonic probe holder. The ultrasonic scanner can be made small in size, is capable of freely adjusting the rotatingly reciprocating motion, i.e. the head-shaking motion of the ultrasonic probe, and permits readily detecting the rotation angle of the rotating shaft. In addition, the scanner can be housed satisfactorily in a sealed vessel filled with a transmission medium of the ultrasonic beam.
