PROBLEM TO BE SOLVED: To prevent generation of resonance on a setting floor surface by a moving cycle on a mechanical device to intermittently move a heavy weight constitutional element. SOLUTION: Movement of a part feeding table 12 heavy in weight by loading a large number of part cassettes 5 on it generates resonant vibration when its moving cycle becomes approximate to a resonant cyle of the floor surface on an electronic part mounting device which is one example of a mechanical device. As this moving cycle can be judged, a motion program, operational control to change moving speed, timing, etc., of the part feeding table so as to shift the moving cycle at the time when it becomes the moving cycle. |
