Apart from the massage mechanism 2, the vibrator 90 for vibrating the calf is incorporated in the footrest 91.

As shown in FIG. 1, the massage device of the present invention can be operated by operating the remote controller 7.

As shown in FIG. 5, the remote controller 7 includes a display device 71 and a plurality of operation buttons 72 on a vertical casing 70 surface. On the right side of the casing 70, a pulse sensor 52 composed of a light emitting element and a light receiving element and a skin temperature sensor 53 composed of a thermistor are provided, and on both sides of the casing 70, A skin electrode reflection sensor 51 (hereinafter referred to as a GSR sensor) composed of a pair of electrodes 51a and 51b is provided, and when the left hand is held by the left hand as indicated by the dashed line, the food is a skin temperature sensor ( 53, the middle finger is brought into contact with the pulse sensor 52, the one finger 51b of the ring finger and the little finger GSR sensor 51, and the palm of the other hand 51a of the GSR sensor 51. GSR is the inverse of skin electrode resistance.

The display device 71 of the remote controller 7 is shown in FIG. A plurality of display means 97 is provided which shows the degree of stiffness of the part corresponding to the "neck / shoulder", "back", "waist", "leg", and the part to which massage is performed. Each display means 97 is composed of LEDs capable of emitting a plurality of colors. Each LED is a combination of an LED device emitting red light and an LED light emitting green light, and when the red LED light only emits red, the color becomes naturally red. If only the green LED device emits light, of course it becomes green as a whole.

The degree of stiffness is determined based on the biometric information from the pulse sensor 52, the skin temperature sensor 53, the GSR sensor 51, and the like. Judging based on that. The massage is performed by a different method of massage such as rubbing, tapping, and rubbing, and determining the degree of stiffness for each massage, and displaying the result with separate LEDs. To this end, three LEDs 97 which display the determination result for each massage corresponding to each part are arranged side by side in a row.

Specifically, in FIG. 6, the leftmost LED of each part (excluding the leg) indicates the degree of stiffness corresponding to the "tap" massage, and the center LED indicates the degree of stiffness corresponding to the "rub" massage. The rightmost LED indicates the degree of stiffness corresponding to the "rubbing and rubbing" massage. The "leg" region indicates the degree of stiffness corresponding to the "vibration" massage.

For example, when it is determined that the "neck / shoulder" part is stiff, the LED 99 on the left side which is a display of "a feeling of stiffness in the neck / shoulder" is turned on.

Fig. 4 shows a control system configuration of the massage device, wherein the bioinformation sensor 5 composed of the GSR sensor 51, the pulse sensor 52 and the skin temperature sensor 53 is a control circuit 6 made of a microcomputer. Is connected to the input port. The other input port of the control circuit 6 is connected to a start button 54 which should be operated at the start of the massage operation, and a mode selector 55 which is operated when switching between the relaxation mode and the refresh mode. It is. 4, only the start button 54 and the mode selection button 55 which are related to this invention among the various operation buttons 72 of the remote controller 7 are shown.

The lifting motor 22, the rubbing motor 31, and the percussion motor 37 are connected to the output port of the control circuit 6. In addition, the display device 71 is connected.

The control circuit 6 starts in the mode selected by the mode selector 55 when the start tool 54 is operated. First, a preliminary description will be made based on the signal from the biometric information sensor 5. After performing the massage procedure, the procedure of the present massage described later is performed.

FIG. 10 shows the relationship between the biometric information detected by the biometric information sensor 5, that is, GSR, skin temperature and pulse rate, and the degree of activity of the autonomic nervous system. As shown, changes in GSR, skin temperature, and pulse rate vary depending on the degree of activity of the autonomic nervous system. When activity is low, GSR and pulse rate decrease, and skin temperature rises. When the activity is slightly low, the GSR is in a stabilized state, but the skin temperature rises and the pulse rate decreases. When the activity is slightly high, GSR rises in a steady state, the skin temperature decreases, and the pulse rate rises. In addition, when the activity is high, the GSR increases significantly, the skin temperature decreases, and the pulse rate increases.

When the biological information changes in this way, the psychological state of the subject can be estimated to be relaxed and relaxed when the activity is low, and when the activity is slightly high, for example, when the massage is performed on a loose area, It can be presumed to be a psychological state in which both are sick and pleasant, and when the activity is high, it can be presumed to be a state of feeling sick. Moreover, when activity is neutral, it can be estimated that it is a neutral state which neither feels good nor hurts.

In other words, the higher the activity, the greater the degree of stiffness, and conversely, the lower the activity, the greater the degree of relaxation.

By varying the GSR, the skin temperature and the pulse rate while applying various massages to each part of the subject, the degree of relaxation and the degree of stiffness of each part of the subject can be estimated from the relationship of FIG. This detection sequence is performed by preliminary massage.

The preliminary massage is first performed by tapping the massage at the "neck / shoulder" position, and the degree of stiffness and relaxation of the site is determined by the biometric information detected by the biometric information sensor 5. The result is displayed by the leftmost LED 97 of the three LEDs corresponding to the "neck / shoulder" position of the display device 71. Next, a "tap" massage is performed at the "back" position to determine the degree of stiffness and relaxation of the site, and the result is the leftmost of the three LEDs corresponding to the "back" position of the display device 71. Indicated by LED 97. Next, a "tap" massage is performed at the "waist" position, and the degree of stiffness and relaxation of the portion is similarly determined, and the result is the leftmost of the three LEDs corresponding to the "waist" position of the display device 71. Is indicated by LED 97.

After the "tap" massage, the calf is vibrated and massaged with the vibrator 90 to determine the degree of stiffness and relaxation of the site, and the result is one corresponding to the "leg" position of the display device 71. Indicated by LED 97.

Next, the "rub" massage is performed at the "waist" position, and the degree of stiffness and relaxation of the portion is determined as in the case of the "tap" massage, and the result is placed at the "waist" position of the display device 71. Indicated by the central LED 97 of the three corresponding LEDs. Next, rub and rub at the "back" position to determine the degree of stiffness and relaxation of the area, and the result is the center LED of the three LEDs corresponding to the "light" position of the display device 71. Indicated by (97). Next, the "rub" massage is performed at the "neck / shoulder" position, and the degree of stiffness and relaxation of the part is similarly determined, and the result is determined by three corresponding to the "neck / shoulder" position of the display device 71. Indicated by the LED 97 in the center of the LEDs.

After the rubbing massage is completed, tap and rub the massage from the neck / shoulder to the back and the waist. Similarly, the GSR, the skin temperature and the pulse rate of each part are applied to each part. The degree of stiffness and the degree of relaxation are determined, and the result is displayed as the rightmost LED 97 of the three LEDs corresponding to each part of the display device 71.

Even in the same area, if the types of massage are different, the response of the bioinformation sensor 5 is different. For example, if the result is that the "rub" massage is more active than the "tap" massage, it can be assumed that rubbing massage is more effective than tapping massage.

As described above, after determining the degree of stiffness and the degree of relaxation for each of the plural types of massages in each site, a comprehensive judgment described later is performed.

7 shows a flowchart of the preliminary massage.

First, in step S1, the live waveform is received from the GSR sensor, and it is judged whether or not abnormality in the waveform generated by the hand being removed from the sensor is confirmed. When it judges, abnormal display is performed in step S2. The abnormality display lights up all the LEDs 97 of the display device 71 in red, for example. When the waveform is normal, the noise removing process is performed in step S3, and then the flow advances to step S4 to detect a change in the GSR in each phase section (each massage operation, that is, the period during which tapping is performed). . For the detection of the slope, a method of calculating the slope of the GSR change by, for example, the least squares approximation can be adopted.

In step S5, the live waveform is received from the pulse sensor to determine whether or not the waveform is abnormal, and when it is determined as "yes" here, the abnormal display is performed in step S6. When the waveform is normal, after the noise removing process is performed in step S7, the pulse rate is detected in step S8. Thereafter, the flow advances to step S9 to detect a change in the pulse rate in each phase section. For the detection of the slope, a method of calculating the slope of the pulse rate change by, for example, the least squares approximation can be adopted.

In step S10, the live waveform is received from the skin temperature sensor to determine whether or not the waveform is abnormal, and when it is determined to be "yes", the above display is performed in step S11. When the waveform is normal, the noise removing process is performed in step S12, and then the flow advances to step S13 to detect a change in skin temperature in each phase section. For the detection of the slope, for example, a method of calculating the slope of the skin temperature change by the least squares approximation can be adopted.

After execution of steps S4, S9 and S13, the process proceeds to step S14, and the psychology of the subject is determined from the combination of the change in GSR (ΔG), the change in skin temperature (ΔT), and the change in pulse rate (ΔH). The states "Sick", "Active", "Neutral" and "Relax" are determined. Here, "active" refers to a case in which both feelings of feeling pain and good feeling are felt. In addition, "sick" and "active" are regarded as having a high degree of stiffness, "relax" is considered to have the smallest degree of stiffness, and "neutral" is considered to be slightly stiff.

FIG. 9 formulates the estimation of the degree of autonomic nerve activity based on the relationship shown in FIG. Here, the constants A, B, and C representing the degree of GSR change are in the relation A <B <C.

Subsequently, in step S15 of FIG. 7, the determination result of the degree of stiffness with respect to each phase (each massage operation in each site | part) is displayed on the display apparatus 71 as mentioned above. That is, LEDs 97 corresponding to the order of stiffness are displayed in red, orange, and green colors by color. Specifically, in the case of "sick" and "active", it lights in red, in the case of "neutral", it lights in orange, and in the case of "relax", it lights in red. After repeating steps S4, S9, S13, S14, and S15 for each number of phases, the flow advances to step S16 to determine the overall degree of stiffness in each part from the determination result of each phase.

The determination of the degree of overall stiffness is performed as follows. It demonstrates based on the flowchart of the comprehensive determination of FIG. In each part, the degree of stiffness is judged for each kind of massage (in this case, three types), and the result is displayed by three LEDs 97. However, the degree of stiffness is the highest among three LEDs 97 in each part. If the number of LEDs that are determined to be high and lit in red is one or less, the degree of stiffness is determined to be small, if two, it is determined to be frosted, and if it is three, it is determined to be very frosted. And when there are two or more, LED 99 of the corresponding site | part of the comprehensive determination display part 98 is lighted, and it informs that the site | part is formed (step S1-S2). At the same time, the lighting states of the three LEDs in each site are changed as follows.

That is, in each site, the LEDs 97 arranged in a horizontal line are lit up in red from the left by the number which is determined to be the most plentiful and is lit in red (step S3).

For example, in the region of the "neck / shoulder", as shown in FIG. 11, the degree of stiffness is largest for the "tap" massage, and the LED is lighted in red, and for the "rub" massage, the degree of stiffness is moderate and the LED is When the LED is lit in red while the degree of stiffness is greatest and the LED is lit in red with respect to the `` rubbing while rubbing '' massage, the overall judgment is determined to be two red LEDs, and three in a row as shown in FIG. The two LEDs are lit in red from the left side of the LEDs arranged in the left and the rightmost LEDs are turned off. If only one LED is lit in red, only one rightmost LED is lit in red (steps S4 to S5). If the LED lit in red is zero (0), all LEDs are turned off (step S6). .

In each part, such a comprehensive judgment result is displayed by changing the lighting state of the LED so that the degree of stiffness is as if it is displayed by a bar graph, and the effect is visually enhanced.

FIG. 11 shows an example of the display device 71 before comprehensive determination, and as shown in FIG. 12 when this state is determined. In this case, it is judged that "neck / shoulder" and "waist part" are combined. In these figures, the center of each LED 97 frame is indicated by a vertical line in red, an inclined line in orange, and a horizontal line in green. In the center of the LED 99 frame, the lighting state is indicated by a vertical line.

In this case, only the red LED is turned on and the remaining LEDs are turned off, but the green LED may be turned on.

After performing such a preliminary massage, this massage is started. The massage movement is performed based on the result of the preliminary massage, in order to perform various kinds of massage movements (tapping, rubbing, rubbing, rolling, etc.) to each part according to the relaxation mode or the refresh mode. .

Massage movement in Relax mode is a program that increases the relaxation degree of the subject.As the stiffness degree is large, massage is performed for a short time for a part that feels painful when massaged, and the stiffness degree is small. Long-term massage is performed about the site | part determined to be.

The massage operation in the refresh mode is a program that increases the activity of the autonomic nervous system. Specifically, the massage operation is to focus on the area determined to be stiff.

In the above embodiment, the degree of stiffness is displayed by color at the time of stiffness. However, when the degree of stiffness is given by the degree of relaxation in the opposite relationship, the degree of relaxation may be displayed by color. In other words, the LEDs are turned on in red, orange, and green in the order of stiffness, but the green, orange, and red colors are displayed in large order in terms of relaxation.

In order to perform the comprehensive determination of the degree of relaxation instead of the comprehensive determination of the degree of stiffness, of the three LEDs 97 in each part, it is determined that the degree of stiffness is the smallest (the degree of relaxation is large) and is lit in green. If it is three, it is determined that the degree of relaxation is sufficient, if it is two, it is determined that it is relaxed, if it is one, it is determined that it is not so relaxed, and if it is zero, it is determined that it is not relaxed at all. In the case of two or more cases, the corresponding part of the comprehensive judgment display unit 98 is turned on to inform that the part is relaxed. At the same time, the three LEDs in each part change the lighting state as follows, as opposed to the case of comprehensive determination of stiffness.

That is, in each part, the LEDs 97 arranged in a horizontal line are turned on from the left as many as the number which is determined to be the most relaxed and lit in green, and the remaining LEDs are turned off.

As described above, in the comprehensive determination, the degree of stiffness may be displayed for each color in accordance with the degree of stiffness, or the degree of relaxation may be displayed for each color in accordance with the timing of relaxation. In this case, it is sufficient to display the degree of stiffness by lighting red from one end of the LEDs arranged in a horizontal line to display the degree of stiffness from one end, and to display the degree of relaxation by lighting green from the other end.

In the above embodiments, the degree of stiffness and the degree of relaxation are divided into three stages, and the number of display means (LEDs) of the color indicating the largest case is determined in the case of the comprehensive judgment, and the overall judgment display is also performed in the color displaying the greatest degree. For example, the degree of stiffness and relaxation may be divided into more steps. In this case, the criterion for determining that the degree of stiffness and the degree of relaxation is large may not be the largest degree, and the display color used for comprehensive determination may not be the color indicating the largest degree.

According to the present invention, since the degree of stiffness and / or relaxation of the sample is determined based on the biometric information detected by the biometric information sensor, and the degree is displayed for each color, the degree of stiffness or the degree of relaxation can be easily recognized. For example, it can be used for massage in many ways, such as adjusting the intensity and time of massage according to the degree of stiffness.

In addition, since the degree of stiffness and / or relaxation of the subject was determined for each massage while performing a plurality of types of massage movements on a predetermined portion of the subject, the results determined for each massage were distinguished and displayed. He can set the criteria for which massage will work best for this area.

In addition, after determining the degree of stiffness and / or relaxation of the subject for each massage at a predetermined part of the subject, and displaying the result by the display means, the comprehensive judgment of the degree of stiffness and / or relaxation of the subject at that part is determined. Since the results are displayed as display means, the overall degree of stiffness and the degree of relaxation at the site can be easily recognized.

In addition, a plurality of display means for displaying the degree of stiffness and / or the degree of relaxation is arranged in a row for each massage for each part. When comprehensively determining the degree of stiffness and / or the degree of relaxation, the degree of stiffness and / or relaxation at the site is The display of a large degree of accuracy is performed by the number of display means, and the result of the comprehensive determination is displayed by a color indicating a large state of stiffness and / or relaxation degree by the number from either of the display means arranged in a line. As a result, the degree of stiffness and / or relaxation can be as if displayed on a bar graph, thereby enhancing the effect visually.
