<p><P>PROBLEM TO BE SOLVED: To realize smooth actuation without any hunting actuation when drivingly controlling respective actuators for a back part and a knee part in preset ideal actuation patterns in a Gatch bed. <P>SOLUTION: A control part 7 is provided with a storage means dividing the actuations of the back part 2 and the knee part 4 into a plurality of actuation areas by using an ideal actuation pattern as a reference and storing actuation pattern maps, wherein a drive control command approximates the actuations to the ideal actuation patterns is set, in the actuation areas; and a driving command output means determining in which actuation areas are the present positions of the respective back and the knee positioned in the actuation pattern maps based on back and knee position detecting sensors 11 and 12 and outputting the driving control command preset in the actuation areas to the back and knee actuators 8 and 9. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
