<p>PURPOSE:To easily and correctly measure the occluding movement condition of a testee on the side of a treatment chair by providing a lower jaw movement probe, an A-D converter, an angle lead-through circuit and a motion locus lead-through circuit. CONSTITUTION:A low jaw movement probe 2 incorporates a horizontal angular speedsensor 6 and an arrowhead face angular speed sensor 7 to detect the horizontal angular speed of the low jaw of a testee and the arrowhead face angular speed of the low jaw. A-D converters 26, 27 A-D convert output of the probe 2. Angle lead-through circuits 28, 29 integrate output of the A-D converters, the low jaw planing speed and the low jaw opening speed to lead through the horizontal angle and the arrowhead face angle. The motion locus lead-through circuit 30 leads through the motion locus of of low jaw from the respective angles. Thus, the occluding movement condition of a testee can easily and correctly be measured on the side of a treatment chair.</p> |
