Ultrasonic wave diagnosing apparatus having an ultrasonic wave transmitting and receiving part transmitting and receiving ultrasonic waves

摘要

The ultrasonic wave diagnosing apparatus of this invention comprises a controlling circuit controlling the rotation, advance and retreat of an ultrasonic wave oscillator, a DC power source feeding an electric power to a DC motor rotating the ultrasonic wave oscillator, a DC motor controlling circuit inputting a controlling signal from the above mentioned controlling circuit and controlling the voltage of the above mentioned DC power source, a photointerrupter detecting the position of the ultrasonic wave oscillator by the advance and retreat, a stepping motor advancing and retreating the above mentioned ultrasonic wave oscillator and a record controlling apparatus controlling an auxiliary memorizing apparatus which can record an ultrasonic wave image obtained by the above mentioned ultrasonic wave oscillator so that, in order to reverse the rotation by inverting the phases of controlling signals A and B of the stepping motor advancing and retreating the above mentioned ultrasonic wave oscillator, a position detecting signal of the above mentioned photointerrupter is input into the above mentioned controlling circuit.
