Abstract

PURPOSE:To achieve rocking in three dimensions with one drive motor, by providing a disc rotatable on a surface at the right angle to one axis to mount a circular arc angle adjusting guide on a plane at the right angle to the disc surface. CONSTITUTION:A screw shaft is provided in a slide guide 1 and a boss section 2 is so arranged to slide along a slide guide 1 with the rotation of the screw shaft. The whole unit is mounted on a rail 6 to be movable along the rail 6. In this mechanism, first, a disc 7 is turned to be fixed at the position at an angle phi with the X axis, then, one end of the slide guide 1 is made to slide along an angle adjusting guide 3 and fixed so as to be at an angle theta with a horizontal plane. This allows the axis of the slide guide 3 to align the orbit of a specified 3-D rocking motion. Then, a drive motor 5 is driven and then, reversed with a limit switch to make the boss section reciprocate in the length of lf=(x<2>+y<2>+z<2>)<1/2> thereby assuring a desired rocking motion.
