Title:
ULTRASONIC DIAGNOSTIC DEVICE
Document Type and Number:
Japanese Patent JP2998502
Kind Code:
B2
Abstract:
PURPOSE: To obtain a cubic fault image by rotating ultrasonic oscillators lined up in a line.
CONSTITUTION: In a tip end section main body 10, in order to rotate a rotary disc 11 on which ultrasonic oscillators are mounted, by means of remote control, paired operating wires 17 are engaged with a pulley 13 connected to the rotary disc 11, the operating wires 17 are led to the inside of an operating section via a slack prevention member at the halfway, and they are designed to be operated so as to be pushed on/pulled in by a motor, so that the rotating angle of the motor is detected by an encoder 23. In order to control the rotating angle of the rotary disc 11 to be 80°, a rotation side control section 40 is projected by the angular portion of 90 out of the inner surface of the pulley 13, and a fixed side control section 41 is also projected by the angular portion of 90° out of a holder 14, so that the fixed side control section 14 can relatively be slid with respect to the inner surface of the pulley 13.
