Subsequently, the vertical motor 5 is turned on downward (S14).
The presence / absence of a pulse signal input from the vertical position detector 43 is detected (S15), and each time a pulse signal is input from the vertical position detector 43, the vertical position counter is incremented by "1" (CT1 ← CT1 + 1), The current position of the treatment element 2 is calculated (S16).

At the same time, the load F applied to the treatment element 2 is detected by the load sensor 100, and a predetermined reference load Ft is set.
Then, it is determined whether the detected load F is equal to or more than the reference load Ft (S17). When the detected load F becomes equal to or more than the reference load Ft, the vertical motor 5 is turned off (S18).

At this time, the one-chip microcomputer 101 determines that the treatment element 2 has reached the shoulder height (C), and stores the value CT1 of the vertical position counter at this time in the shoulder position data Y1.
(Y1 ← CT1) (S19).

The shoulder position is detected by the load sensor 10.
0 is not limited to the method based on the detection of the load on the treatment element 2,
Means for detecting the current value of the vertical motor 5 is provided,
The shoulder position may be detected based on a change in the current value of the upper and lower motors 5 utilizing the fact that the load on the upper and lower motors 5 rises due to contact with the shoulders.

As a method for detecting the shoulder position, means for detecting the rotation of the rotatably supported treatment element 2 is provided, and the non-rotating treatment element 2 contacts the shoulder while not in contact with the human body. The shoulder position may be detected based on the presence or absence of rotation of the treatment element 2 that starts rotating.

FIG. 12 shows the relationship between the shoulder position data Y1 and the physique,
FIG. 9 is a diagram illustrating a method of defining a range of a massage prohibition zone H behind a kidney as a rectangular area. If the height is the same, the position of the built-in body is almost the same regardless of whether the body is lean or obese, so that the range of the massage prohibited zone H can be determined from the height estimated from the shoulder position of the user.

The shoulder position data Y1 obtained from the time data of the vertical position counter CT1 indicates that the smaller the value, the higher the shoulder position. Therefore, between the upper and lower positions Ya and Yb (Ya <Y1 <
Yb) is set to “Standard” and “High” if Y1 ≦ Ya, Y1
The case of ≧ Yb is determined as “low”.

The rectangular area of the massage prohibition zone H is defined by a combination of the values (Yn to Ym) of the vertical position counter CT1 and the values (Xn to Xm) of the left and right position counter CT2 with the origin closer to the spine. The range defining data according to the height is set in the lookup table in advance. If this shoulder position detection mode is executed before executing the automatic course (“upper body course”, “neck / shoulder course”, “lumbar course”), the data of the forbidden zone according to the physique will be used. When the position detection mode is not executed, the forbidden band data of the standard physique person is used.

Next, the procedure for determining a forbidden zone for massage by the massage machine according to the present invention will be described with reference to the flowchart shown in FIG. The shoulder position data Y1 is read from the memory (S21), and it is determined whether or not Y1 is equal to or less than Ya (S22).
If Y1 is equal to or smaller than Ya, the height of the user is determined to be "high" (S23), and the forbidden zone data for the tall person is used.
(S24).

If the result of determination in step S22 is that Y1 exceeds Ya, it is determined whether Y1 is greater than or equal to Yb (S25).
If Y1 is equal to or greater than Yb, the height of the user is determined to be "low" (S26), and the forbidden zone data for a person with a short height is used.
(S27). As a result of the determinations in steps S22 and S25, Y1 becomes Ya
In the case of Yb, the height of the user is determined to be `` standard '' (S2
8), use forbidden zone data for people of standard height (S2
9).

In this embodiment, the height is determined based on the shoulder position. However, the position is not limited to the shoulder position, but may be any other position as long as the vertical position changes in accordance with the height. You may.

In this embodiment, the height is classified into three levels, but the number of levels is not limited to this.

Furthermore, the massage prohibited zone is not limited to the area behind the kidney, which is generally considered dangerous, and may be set to any range that the user wants to avoid massage.

In the present embodiment, the forbidden massage zone is defined as a rectangular area, but the shape is not limited to a rectangular shape.

Further, in this embodiment, the chair type massage machine has been described. However, the same effect as this embodiment can be obtained not only in the chair type but also in the bed type massage machine.

In this embodiment, the motor provided to move the treatment element 2 back and forth, left and right, and up and down has been described. However, the treatment element 2 is moved in a plurality of axial directions by one motor. The same effect as in the present embodiment may be obtained.
