Claims

[Scope of utility model registration request]

A vibrator that is sealed in an ultrasonic medium solution and rotates, a motor that rotates this vibrator via a deceleration mechanism, and a motor that is directly connected to this motor to supply an ultrasonic signal that excites the vibrator and sweep the CRT display. an encoder that transmits a timing signal; a photosensor mechanism that transmits a reference position signal to start emitting ultrasonic waves from the transducer to the object; and an encoder that is directly connected to the rotation axis of the transducer and rotates In a probe consisting of a slip ring that sends and receives ultrasonic signals to and from a transducer, a V-shaped seal is used as a seal for the ultrasonic medium solution and rotates together with the rotating shaft to significantly reduce the load on the motor. A small and lightweight rotary probe characterized in that the case of the probe is made of plastic.
