Abstract
In a probe for observing an ultrasonic image, which obtains the ultrasonic image of an object to be observed such as a body cavity by means of an ultrasonic transmitting and receiving means, a mechanical scanning operation of the ultrasonic transmitting and receiving means is performed by an ultrasonic driving means, and thus it is possible to obtain a good diagnosis image with no distortion and no flicker because noises of the driving means can be reduced. Therefore, an ultrasonic endoscope system and an ultrasonic video endoscope system etc. which utilize the probe mentioned above can display a good ultrasonic image and a good optical image.
