PROBLEM TO BE SOLVED: To concurrently perform the drive with avoiding the position where a plurality of members make interference with one another by sensing the positions of the members furnished on a medical treatment table, and controlling the motion sequence of each member on the basis of the position information obtained. SOLUTION: Rotating angles of a seat plate 3 and a seat back 5 are sensed by potentiometers 9, 10 fixed to their rotational centers. The rotating angles of left and right leg supports 7, 8 in the direction spreading from each other and in the vertical direction are sensed by potentiometers 11, 12 fixed to two shafts as the rotational centers of the leg supports 7, 8. Further a potentiometer 13 senses the rotational angle of the link of a link mechanism which is a height adjusting mechanism, while multi-rotation type potentiometers 14, 15 sense the lengths of the leg supports 7, 8. The results from sensing are fed to a CPU system, which decides the motion sequence so that the members 5, 7, 8, etc., do not interfere with one another. Thus the motion control is established. |
