To 105 and the like, the control circuit 100 is also provided in the main body case 40a.

Next, the operation of the air matting device constructed as described above will be described with reference to the flow charts shown in FIGS. 13 and 14.

First, the power switch 42 provided on the operation panel 41 of the feeding / discharging device 40 is turned on. As a result, the compressor 91 operates and compressed air is stored in the filter tank 92. Then, in step 1, it is determined whether the wave switch 45 or the wave ion switch 47 is pressed. If yes, the process proceeds to step 2, and if no, the process proceeds to step 20.

In step 2, the wave selection switch 4
It is determined by 8 whether or not the A mode to the D mode are selected. If the result is YES, the process proceeds to step 10, and if the result is NO, the process proceeds to step 3. For example, when the L mode is selected, it is determined as NO in step 2 and the process proceeds to step 3.

In step 3, the stepping motor 65
Is driven, and the rotary body 61 of the rotary valve 60 rotates. In step 4, it is determined whether or not the rotating body 61 has rotated to the target position. That is, it is determined whether or not the hole 61b of the rotating body 61 communicates with the through hole 63i of the fixed body 63. This is determined by whether the position detecting means 80 detects the holes 78a to 78d of the meridian E8 and outputs the 4-bit signal "1111". If it is determined NO in step 4, the process returns to step 3, and the driving of the stepping motor 65 is continued to rotate the rotating body 31 further.

When the hole 61b of the rotating body 61 communicates with the through hole 63i of the fixed body 63, the position detecting means 80 detects the holes 78a to 78d of the meridian E8 and outputs a signal "1111".
In step 4, it is judged as yes and the process proceeds to step 5. In step 5, the driving of the stepping motor 65 is stopped, compressed air is supplied to the air bag 38, and the air bag 38 expands.

When the air bag 38 is inflated, as shown in FIG. 4, the pressing members 3 whose tops are pointed by the plate members 38a and 38b.
8c, and the pressing portion 38c presses the calf or the like that is the foot. Since the pressing portion 38c has a pointed shape, the force per unit area for pressing the calf is large, and the foot can be massaged sufficiently.

The stop time of the stepping motor 65 is determined by the setting switches 49 and 50 for setting the strength. When the strength is set high, the stop time becomes long, and when the strength is set weak, the stop time is stopped. The time will be shorter.

When the stepping motor 65 is stopped for the determined predetermined time, a predetermined number of motor driving pulses are output from the control circuit 100 to rotate the stepping motor 65 by a predetermined angle (step 6). ..
By this drive, the rotary body 61 of the rotary valve 60 is rotated by a predetermined angle, and the hole 61b of the rotary body 61 is fixed to the fixed body 6.
It is located between the three through holes 63i and 63b. As a result, all the through holes 63b to 63i of the fixed body 63 are fixed to the rotating body 6
All of the air bags 31 to 38 are communicated with the circular arc groove 61f.
Becomes an exhaust state, and the inflated foot air bag 38 contracts.

In step 7, the needle valve 93 is opened to release the compressed air in the filter tank 92, and then the needle valve 93 is closed. In step 8, it is determined whether or not to end. This is for determining whether or not a set time set by a timer (not shown) has been reached, or whether a stop switch (not shown) has been pressed. If NO, the process returns to step 3, and the operations of steps 3 to 8 are repeated until YES is determined in step 8.

By repeating the operations of steps 3 to 8, the air bag 38 for the foot is repeatedly inflated and deflated.
Then, if YES is determined in step 8, the process ends.

If the answer is YES in step 2, and the process proceeds to step 10, in step 10, the stepping motor 6
5 is driven and the rotary body 61 of the rotary valve 60 rotates. In step 11, it is determined whether the rotating body 61 has rotated to the target position.

Here, for example, when the B mode is selected, it is judged whether or not the position detecting means 80 has detected the hole 71d of the meridian E1. That is, the hole 61b of the rotating body 61
Is communicated with the through hole 63b of the fixed body 63, and if no, the process returns to step 10, the stepping motor 65 is driven, and the rotary body 61 of the rotary valve 60 is driven.
Is rotated further. Then, when the hole 61b of the rotating body 61 communicates with the through hole 63b, the position detecting means 80 outputs a 4-bit detection signal indicated by E1 in the truth table. The driving of the motor 65 is stopped.

By this stop, compressed air is supplied to the air bag 31, and the air bag 31 is inflated. The other air bags 32 to 38 are in an exhausted state. This stop time is determined in the same manner as described above. When stopped for the determined predetermined time, the stepping motor 65 is driven (step 13), and in step 14, it is determined whether or not the rotating body 61 has rotated to the next target position.

Since the B mode is set here, it is determined whether or not the hole 61b of the rotating body 61 communicates with the through hole 63c of the fixed body 63. That is, the position detecting means 8
For 0, it is judged whether or not the holes 72a and 72d of the meridian E2 are detected. If NO, the process returns to step 13 and the stepping motor 65 is driven to rotate the rotary body 6 of the rotary valve 60.
1 is rotated further.

The hole 61b of the rotating body 61 is replaced by the through hole 6
When communicating with 3c, a 4-bit detection signal indicated by E2 in the truth table is output from the position detecting means 80. As a result, YES is determined in step 14 and the process proceeds to step 15. In step 15, the driving of the stepping motor 65 is stopped. Due to this stop, the air bag 32 is inflated.
On the other hand, the inflated air bladder 31 is in an exhausted state and thus contracts.

In step 16, it is judged whether or not to end. If no, the process returns to step 13 and step 16
The operations of steps 13 to 16 are repeated until it is determined to be yes. Based on this judgment, the air bags 31 to 3
8 expands and contracts in sequence. As a result, the massage is repeatedly performed from the neck to the legs. Then, when the time set by the stop switch (not shown) or the timer (not shown) is reached, YES is determined in step 16 and the process ends.

When it is judged NO in step 1, step 2
When the process proceeds to 0, it is determined in step 20 whether the heater switch 43 or the ion switch 46 has been pressed. If NO, the process returns to step 1 and switches 45, 47, 4
The operations of steps 1 and 20 are repeated until 3,46 is pressed. If YES is determined in step 20, the process proceeds to step 21, and the heater 26 and the electric belt 25 are controlled. In step 22, it is judged whether or not to end in the same manner as described above, and if it is judged no, step 21
Then, the operation of steps 21 and 22 is repeated. When it is judged as yes, it ends.

In the above embodiment, the air bags 31 to 33,34 are used.
Although the parts 37 to 37 are arranged so as to partially overlap each other when contracted, it goes without saying that they may be arranged not to overlap each other.

FIG. 15 shows another embodiment of the foot air bag 110, in which a bar material 111 made of a hard synthetic resin is mounted on the air bag 110, and the bar material 111 is attached.
The upper part of the is formed into a pointed pressing portion 112.

In each of the foot air bags 38 shown in FIGS. 4 and 15, the pressing portion is linearly pointed, but it is needless to say that it may be pointed.

In the above embodiment, when the hole 61b of the rotating body 61 is located between the through holes 63b to 63i of the fixed body 63,
Although a predetermined number of pulses are output from the control circuit 100, as shown in FIG.
A hole 113 is provided at an intermediate position between E8 and E8.
