1. An intracavitary diagnosing apparatus comprising:

  • a transducer disposed in an ultrasonic probe for outputting ultrasound in a longitudinal direction of a distal end portion of said ultrasonic probe;

    an ultrasonic mirror disposed in said ultrasonic probe on the distal end side of said transducer for reflecting the ultrasound output from said transducer to direct the ultrasound as a focused ultrasonic beam into an organ; and

    a driving means for moving said ultrasonic mirror and changing a relative distance between said ultrasonic mirror and said transducer in the longitudinal direction of said probe, thereby changing the position of the focused range of the ultrasonic beam, said driving means including a wire mounted on said ultrasonic mirror, whereby said ultrasonic mirror can be driven by the pulling operation of said wire.
