The rotation of 0, 28, 5, and 34 becomes slower when the time T is increased, and becomes faster when the time T is decreased. Thus, the motor 10
-The rotation speed of 28/5/34 can be freely changed.

Next, one example of the movement (trajectory) of the right massaging element 2 at the time of the massage for rubbing is shown in FIG. 19 (a) in which the rotation speed of the motors 10, 5, and 34 is changed from above and from the back, respectively. A description will be given based on FIG. 19B for explaining the control method to be performed and FIG. 20 showing a flowchart at that time. At present, the treatment element 2 on the right side is assumed to be in the position A in FIG. At this time, the front-rear adjustment motor 10, the up-down adjustment motor 5, and the left-right adjustment motor 34 are simultaneously turned on.
Then, the front and rear (pressing), vertical and horizontal (width) positions are detected, and the rotation speeds of the motors 10, 5, and 34 are set,
Then, the treatment element 2 starts moving in a direction in which the three directions of the front-rear direction, the up-down direction, and the left-right direction are combined. While the treatment child 2 is moving,
The rotation speeds of these three motors 10, 5, and 34 are sequentially changed according to the current position in each direction. That is,

It moves by drawing a smooth elliptical locus such as 9 (a). The locus of the left massaging element 2 is shown symmetrically with the locus of FIG.

Here, the direction serving as the control reference is determined as the width direction (left-right direction). Then, when the position in the width direction of the right treatment element 2 reaches the position B in FIG. 19A, the rotation directions of the three motors 10, 5, and 34 are reversed. Next, similarly, the variable speed control according to the current position in each direction is continued until the position in the width direction of the treatment element 2 reaches the position A. As a result, one cycle of the massage of fir tree is realized.

The operation pattern (trajectory) of the massaging elements 2 and 2 in the massage massage is such that the above-mentioned A and B positions which are control positions are changed, and three motors 10, 5, and 34 are used.
Various types can be obtained by changing the speed command pattern. 21 (a) and FIG.
In (b), two different trajectories of the right treatment element 2 are illustrated. Further, by independently controlling the front-rear adjustment motor 10 and the left-right adjustment motor 34 with the up-down adjustment motor 5 stopped, the front-back direction (pressing direction) and the left-right direction (width direction) of the treatment elements 2 and 2 can be controlled. It is possible to massage rice with a combination of movements.
