Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair type massage machine for performing treatment according to an automatic treatment course, and more particularly to a chair type massage machine having an automatic course having a function of relieving stiffness in a designated place.

[0002]

2. Description of the Related Art In a conventional massage machine having an automatic course, a user who is troublesome to select a treatment pattern is left to a user to select one of a number of recommended patterns for treatment. . However, in many cases, the treatment pattern of the above automatic treatment course is fixed, and the treatment is performed uniformly on the whole body from the shoulders to the hips, or the treatment is divided into the neck / shoulder or the hips. The function that a person concentrates on the stiff part that he / she wants to massage is to be performed manually.

As an improved version of this, a massaging machine is known in which a massaging member is reciprocated within a range narrower than the total mass travel range of a massage centered on an arbitrary designated position in order to intensively massage the "vase". (Tokuhei 1
No. 13379).

However, when the user wants to relieve stiffness, the location of the stiffness is limited, and the location of the stiffness is gradually narrowed from the surroundings, and finally it is better to concentrate on the specific location for the treatment. It is effective. Moreover, the person to be treated also desires a massage machine having such a function. However, the Japanese Patent Publication No. 1-13379 has a fixed narrow range and does not have a function of further narrowing the narrow range.

Further, as described above, when it is desired to particularly relieve stiffness in a specific part, it is sometimes desired to stop the vertical movement of the treatment element, that is, the massage unit, and concentrate the treatment at the specific part. For that purpose, conventionally, the only method was to manually move the treatment element, stop it, and manually select the treatment method that one wants to treat. In particular, for many practitioners who select the automatic course, there is no means for receiving intensive treatment while the movement of the treatment element is stopped at such a specific location.

Further, in the above-mentioned in-situ intensive treatment (hereinafter, referred to as fixed treatment), the massage effect is improved when the treatment is performed by combining various treatment patterns, but the fixed treatment in which the treatment pattern is programmed is fixed. There has never been an automatic course.

[0007]

SUMMARY OF THE INVENTION The present invention is a chair type having an automatic treatment course for designating a desired treatment site of a user and intensively treating a specific place (a stiff place). The purpose is to provide a massage machine.

[0008]

In order to achieve the above object, a chair-type massage machine of the present invention has a massage unit that can be moved up and down along a backrest, and performs a treatment according to a pre-programmed automatic treatment pattern. The chair-type massage machine has a program for an automatic treatment pattern that performs treatment in a narrow range around an arbitrary designated position, and when the operation key is operated while performing treatment around the designated position, the above-mentioned treatment is performed. The range is further narrowed each time the key is operated.

Further, in the treatment range, the pulse from the motor is input to the microcomputer to count the number of pulses, and when the count reaches the preset upper limit position and lower limit position of the treatment range, the motor is reversed. Is characterized by.

Alternatively, in a chair-type massage machine having a massage unit that can be moved up and down along a backrest and performing treatment according to a pre-programmed automatic treatment pattern, the treatment is performed without moving the treatment element at any designated position. It is characterized by having a program of a fixed automatic treatment pattern. Furthermore, in the fixed automatic treatment pattern, treatment units such as rolling and stretching for performing treatment in a narrow range centered on the arbitrary designated position are interwoven.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below. FIG. 6 is a perspective view showing the appearance of a chair-type massage device to which the present invention is applied. Further, FIG. 7 is a cross-sectional view of FIG.

The massage device comprises a backrest portion 10, a seat portion 11 and a footrest portion 14. Seat part 11
An electric reclining mechanism and a control device (not shown) are housed inside. A back frame is arranged in the backrest 10 of the massage device, and inside the back frame,
A massage unit 12 is held in the back frame so that it can slide up and down. In FIG. 6, for convenience of explanation, the portion 13 in which the back massage unit is stored and the footrest portion 14 are cut open. The massage unit 12 is fitted with a vertical feed screw (not shown), and the feed screw is rotatably held by the back frame. A pulley is attached to the lower part of the feed screw and is connected to a vertical movement motor attached to the back frame via a belt. The vertical movement motor is a control device (CP).
Under the control of U), normal rotation and reverse rotation are possible at any speed. The rotation of the vertical movement motor is transmitted to the feed screw,
The massage unit is configured to be movable between upper and lower movement limit position detecting limit switches (not shown) attached to the back frame.

The massage unit 12 is equipped with a clutch and a treatment drive motor. The rotation of the treatment drive motor causes a roller (firball) which is a treatment element to swing back and forth and / or left and right, Kneading massage, kneading (or shiatsu) massage, kneading kneading (or shiatsu)
Take action.

The outline of the known massage unit will be described below. FIG. 15 shows the arrangement of parts when the massage unit is viewed from the front, and includes a hitting shaft 39, a kneading shaft 51, and a roller arm 5.
6 and a roller (firball, treatment element) 24. The eccentric shafts 40 and 41 fixed to both ends of the hitting shaft 39 and the two roller arms 56 are respectively the ball joints 5.
7 are engaged. The ball joint 57 is slidable in the axial direction of the eccentric shafts 40, 41, and the eccentric shafts 40, 41 and the two roller arms 56 can be engaged with each other at an arbitrary angle.

The helical gear 43 is engaged with the helical gear 50 fixed to the kneading shaft 51. Two eccentric inclined cylindrical members 54 are fixed to both ends of the kneading shaft 51, and permanent magnets 52 for detecting the rotational position are fixed. Further, the roller 24 shown in FIG.
The Hall element 53 is arranged at a position facing the permanent magnet 52 at the rotational position where the width of the hall becomes the narrowest. A slider 55 having a substantially rectangular outer shape is rotatably attached to the eccentric inclined cylindrical member 54 with respect to the eccentric inclined cylindrical member 54, and the slider 55 slides only in a direction substantially parallel to the paper surface of FIG. It is movably fitted to the roller arm 56.

Next, each operation will be described. "Strike"
In the case of, the power of the motor is transmitted to the striking worm, and the striking shaft 39 rotates. Then, since the eccentric shafts 40 and 41 arranged at rotational positions different in phase by 180 degrees rotate while being eccentric, the roller arm 56 and the roller 24 are rotationally driven via the ball joint 57, and the left and right rollers 24 are moved. Alternately project and strike. It is possible to strike at any width position of the roller 24.

In the case of "rubbing", the power of the motor is transmitted to the rubbing worm gear and the rubbing shaft 51 is rotated. Two eccentric inclined cylindrical members 54 are fixed to both ends of the kneading shaft 51, and a slider 55 having a substantially rectangular outer shape is attached to the eccentric inclined cylindrical member 54.
It is attached so that it can rotate with respect to the slider 5
Reference numeral 5 is fitted to the roller arm 56 so as to be slidable only in a direction substantially parallel to the paper surface of FIG.

Therefore, when the rubbing shaft 51 is rotated, the direction of the inclined surface of the eccentric inclined cylindrical member 54 is rotated, and the surfaces of the slider 55 and the roller arm 56 maintain the same surface as the inclined surface. The roller arm 56 and the roller 24 swing left and right around the inclined cylindrical member 54, so that the interval between the rollers 24 becomes wider or narrower.

By rotating the kneading shaft 51,
When the hall element 53 detects the permanent magnet 52, the width between the left and right rollers is the narrowest position. The number of times of rubbing is counted by the detection signal of this Hall element. The width position of the roller 24 is determined by setting the drive voltage and drive time of the motor with reference to the narrow position detected by the hall element 53. Therefore, the width position of the roller 24 can be arbitrarily controlled by controlling the drive voltage and drive time of the motor based on the detection signal from the hall element 53. When both rubbing and tapping are performed simultaneously, the power of the motor 25 is transmitted to both the tapping shaft 39 and the rubbing shaft 51, and the above-described rubbing and tapping operations are performed simultaneously.

The structure and operation of these are well known,
Details are disclosed in Japanese Patent Application Laid-Open No. 2001-258972.

Indicates the state It is a surface view.

As shown in FIGS. 8 and 9, the base plate 31a of the massage unit 31 is formed by sheet metal working, and the flanges 31b on both sides of the base plate 31a are formed.
Each of the three rollers 31c is provided on the shaft, and moves up and down while rolling along a seat frame in a seat back (not shown). A gear box 32 is attached to a substantially central portion on the rear surface side of the base plate 31a, and a kneading shaft 33, a tapping shaft 34, and a finger-pressure shaft 35 are axially mounted on the gear plate 32 in three stages arranged vertically. In the gear box 32,
Gear reduction mechanisms G1, G2, G3 formed of a worm gear mechanism or the like corresponding to the shafts 33 to 35 are housed (see FIG. 1).
2). Worm G1a and worm wheel G1b (Fig. 1
The gear reduction mechanism G1 for the kneading shaft 33 described in 1) is driven by the kneading drive motor 37 via the belt 36 (FIG. 12) to rotate the kneading shaft 33. Similarly, the tapping shaft 34 is
It is rotated by a gear reduction mechanism G2 for a beating shaft 34 driven by a beating drive motor 139 via a belt 38 (FIG. 9). Similarly, the worm G3a and the worm wheel G3
The gear reduction mechanism G3 for the acupressure shaft 35 is a belt 1
The acupressure shaft 35 is driven by the acupressure drive motor 141 via 40 (FIG. 12). Thus, the kneading drive motor 37, the belt 36, and the gear reduction mechanism G1 form a kneading drive unit, which is a beating drive motor 39 and a gear reduction mechanism G
2. The striking drive unit by the belt 38 further includes the acupressure drive motor 141, the belt 140, and the gear reduction mechanism G3.
Thus, the acupressure driving units are respectively formed. In addition,
The belt 140 may be a toothed belt, a flat belt, a V-belt, or the like.

In this way, in the two left and right watermark windows 31d (FIG. 8) formed by cutting out the base plate 31a, a treatment link for performing a rubbing motion, a tapping motion, and a shiatsu motion by each of the kneading, tapping, and shiatsu driving units. With the means 142 supporting the treatment element 143, the treatment element 143 is passed through from the rear surface side to the front surface side.

Next, the structure of the newly developed treatment link means 142 shown in FIGS. 10 and 11 will be described. It is as follows. That is, the treatment link means 142 is a pantograph-shaped four-bar rotary link mechanism in which four links L1 to L4 are rotatably coupled by four pins P1 to P4 (also referred to as “rotary coupling portions”), The pin P3 is coaxially supported so as to be swingable with respect to the kneading shaft 33. The four-node rotary link mechanism 142 moves in a pantograph manner with the rotary coupling portion of the pin P3 as a fixed point. Each of the links L1 to L4 is preferably made of a hard synthetic resin material in order to satisfy the requirements for weight reduction, quietness, and mechanical strength, but a sheet metal product may be used as appropriate. May be a combination of. The return spring 1 is provided between the link L2 and the treatment arm 144 that rotatably supports the treatment element 143.
45 (FIG. 8) is stretched, and the treatment arm 1 is provided by its spring force.
44 is always biased in the arrow Z direction (FIG. 11). The treatment arm 144 is swingably supported by the pin P1 that is an opposed rotary coupling portion that is disposed opposite to the pin P3.

The pin P3 corresponds to a protruding kneading shaft 33a protrudingly provided on the shaft end of the kneading shaft 33, which will be described later, and serves as a driving shaft for imparting a kneading motion to the treatment link means 142 by the rotation of the kneading shaft 33. In addition, the pin P3 functions as a swing center for swinging the link L3 and the link L2 of the treatment link means 142 when the treatment element 143 strikes or performs shiatsu movement described later.

A tapping push rod 146 is provided between the tapping shaft 34 and the link L3. In order to allow the movement of the link L3 during the kneading movement, the upper end of the hitting push rod 146 has a ball joint 146.
The link L3 is coupled via a (FIG. 10), and the lower end 146b of the push rod 146 is coupled so as to allow swinging in a direction perpendicular to the paper surface of FIG.

The acupressure shaft 35 for performing the acupressure motion added as a newly developed massage motion is provided between the acupressure shaft 35 and the link L2 in the same manner as the above-mentioned massaging shaft 33.
An acupressure push rod 147 is provided. The upper end of the acupressure push rod 147 has a ball joint 147a.
(FIG. 10) via the link L2, its lower end 1
The link 47b is coupled so that the link L2 is allowed to swing in a direction perpendicular to the plane of FIG.

Next, as shown in FIGS. 11 and 12,
The above-described four-bar rotary link mechanism 142 is installed in the gear box 32.
And the massage unit 31 is formed. First, the relationship between the kneading shaft 33 and the pin P3 will be described.
The pin P3 is formed so that both shaft end surfaces of the kneading shaft 33 are inclined with respect to the longitudinal axis of the kneading shaft 33, and the protruding kneading shafts 33a and 33b project in a direction substantially orthogonal to the inclined surface.
Is provided, and the links L2 and L3 are coaxially supported by the shafts 33a and 33b. Then, the main surface of the four-node rotation link mechanism 142, which is the treatment link means, has its main surface protruding and kneaded.
It is arranged so that it exists in a plane oriented in a direction substantially orthogonal to b. In this way, a pair of treatment link means 142 is provided on the left and right of the gear box 32. When the beating shaft 34 and the acupressure shaft 35 are stopped, only the kneading shaft 33 rotates, so that the four-node rotation link mechanism 142 can knead.

Next, the mounting structure of the beating shaft 34 and the beating push rod 146 is as follows. Eccentric shafts 34b and 34c are provided at both ends of the beating shaft 34 at positions where their phases are opposite to each other, offset from the center of rotation of the main shaft 34a of the beating shaft 34. The lower end of the hitting push rod 146 is pivotally supported by the eccentric shafts 34b and 34c. That is, as a result, the left and right push rods 146 are alternately moved up and down by the crank movement of the eccentric shafts 34b and 34c. The link L3 swings around the pin P3 in accordance with the vertical movement of the tapping push rod 146, and the shoulder can be tapped.

Acupressure shaft 35 and acupressure push rod 147
With respect to the attachment structure of and, the eccentric shafts 35a and 35b are provided at both ends of the acupressure shaft 35 so as to project, as in the case of the tapping shaft 34. However, unlike the case of the beating shaft 34, since both the eccentric shafts 35a and 35b are arranged in the same phase in left-right symmetry, the left and right push rods 147 both move up and down in the same direction. As the acupressure push rod 47 moves up and down, the pair of left and right links L2 is pin P
Simultaneous swinging in the same direction around 3 enables shiatsu massage.

The massage motion by the massage unit 31 can be controlled by an electronic control system so that each of the above motions can be performed independently, but any two massage motions can be combined or three motions can be performed. The massage movements can be controlled to work in combination at the same time. Further, it is possible to control the strength or speed of each movement or to operate the movement.

The operation of the massage machine will be described. First, as shown in FIG. 11 and FIG. 12, in the kneading motion mode, only the kneading drive motor 37 drives and the hitting push rod 146 and the acupressure push rod 14 are driven.
7 does not move. Therefore, the treatment link means 142 is restrained in a stopped state, and only the kneading shaft 33 rotates,
The treatment link means 30 performs a tilting movement by the kneading shaft 33, and the treatment link means 142 moves so as to draw a kneading movement trajectory as a whole. Therefore, the treatment element 143 can approach the treatment link means 30 in the direction of the arrow N or be separated in the direction of the arrow D to perform a kneading motion to massage the shoulder of the user.

As shown in FIG. 13, in order to perform the tapping motion mode, only the tapping drive motor 139 is driven. Since the acupressure shaft 35 is stopped, the movement of the link L2 is fixed. Hitting Push Rod 1
Since only 46 moves up and down, only link L3 is pin P3
The four-node rotation link mechanism 142 makes a pantograph movement by swinging about. At this time, since the lever ratio is larger than that in the acupressure movement mode, the amount of movement of the massaging element 143 in the front-back direction is larger than that in the acupressure movement mode. Thus, the pair of four-bar rotary link mechanisms 142 arranged on the left and right sides.
13 so that the center point of the pin P1 draws the locus Q.
The deformation is performed by repeating the closed state shown in (a) and the opened state as shown in FIG. As a result, the pair of left and right treatment elements 143 alternately perform left and right tapping motions, and the shoulder tap of the user can be treated.

As shown in FIG. 14, when the acupressure movement mode is performed, only the acupressure drive motor 141 is driven. The tapping shaft 34 and the push rod 1 for the tapping
46 has stopped, so the movement of link L3 is fixed,
Only the acupressure push rod 147 moves up and down. Therefore, only the link L2 swings around the pin P3.
Therefore, as a result, the pantograph mechanism as the four-bar rotation link mechanism, that is, the treatment link means 30 is pin P.
Deformation is performed repeatedly between the closed state as shown in FIG. 14A and the opened state as shown in FIG. 14B so that the center point of 1 draws the locus R. As a result, it is possible to cause the treatment element 22 to perform acupressure exercise and to apply acupressure massage to the user.

FIG. 1 shows a remote control display section of the chair type massage machine of the present invention. As can be seen from the display unit 1, the chair type massage machine of the present invention is provided with the following six types of automatic treatment courses. (1) Respiratory detection course Detects respiration, relaxes the body with rhythmical movements that match the respiratory cycle, and induces sleep. (2) Relaxed course With a monotonous rhythm that is gentle to the body, it gently stimulates the entire body and induces relaxation. (3) Refreshing course By stretching the back muscles, the whole body is stretched and the fatigue of the body is healed. (4) Rigid loosening course Recovers muscle fatigue with intensive stimulation with a stimulating sensation. (5) Point course The selected point is locally stimulated. (6) Area course Focusing on a certain range centered on the selected point, and making a round trip stimulation.

As shown in FIG. 2, in the above (1) to (4), by selecting from three types of treatment ranges of neck, shoulder, upper body, and waist, a total of 12 types of automatic courses can be experienced. Therefore, the automatic course has a total of 14 types of courses.

The present invention relates to the above (5) and (6), and is selected as shown in FIG. That is, FIG.
In case of manual treatment, above (5), (6)
Moves the massage ball (treatment element) up and down with the massage head up / down switch 2 in FIG. 1 to search for the treatment location (5 in FIG. 3), and after determining the treatment location, press the point switch (1 in FIG. 3).
1), the one-point concentrated automatic course at the position where the fir tree ball exists, and when the area switch is pressed (8 in Fig. 3), the automatic course in a narrow range centered on the position where the fir tree ball exists To do. Furthermore, when the point switch or area switch is selected at a favorite part of the automatic course (11, 8 in FIG. 3), the point course or area course starts on the spot (12, 13 in FIG. 3). When the area course selection key is pressed again, the treatment range of the area course is further narrowed (14 in FIG. 3).

4 and 5, the area course (an automatic treatment pattern for performing treatment in a narrow range around an arbitrary designated position) and a fixed course (the treatment is performed without moving the treatment element at the arbitrary designated position). An example of a specific treatment pattern (fixed automatic treatment pattern) will be described. As described above, when the area course is selected and then the area course button is pressed (9, 10 in FIG. 3), the control is performed to narrow the range of the treatment area by one step. This is because the treatment method is effective in loosening the treatment by slightly expanding the treatment area around the stiffness area and then gradually confining it to the stiffness area.

The area course will be described in detail below. (Example 1) -The treatment area range is the position where the pulse of the motor is input to the microcomputer from the stiffness point selected by the user to count the number of pulse inputs, and the position reaches a predetermined count. The upper and lower limits of the area are controlled by reversing the motor.・ When selecting the area course for the first time, the area course is set with the position where the motor pulse is counted about 1700 pulses from the input position centered on that position as the upper and lower limit range (about 3400 pulses in the entire movement range). Set. This is set in a movement range that is almost the same as the movement range when performing partial range treatment of the "neck / shoulder" and "waist". -When the area course is selected again for the second time during the area course, the upper and lower limits (about 2400 pulses of the total movement range) in which about 1200 pulses from the motor are counted from that input position centering on that position ), The area course treatment is performed within the range narrowed by one step, and if the area course is further selected, the position where the motor pulse is counted about 700 pulses from the input position around that position is the upper and lower limit range (total About 1 in the moving range
(400 pulses), an area course limited to a narrower range is performed, and the more the course is selected, the more the treatment range is controlled so as to concentrate on the specific portion to be massaged by the user. In this embodiment, the treatment area is limited in three stages, and when the area course button is selected, the treatment range in the initial stage area course is restored. It should be noted that this setting is not limited to three stages, and the final range may be fixed treatment without the movement range of the treatment element. At this time, the treatment element can be moved up and down by the massage head upper limit switch 2 in FIG. 1 to arbitrarily adjust the center position of the area range.

(Embodiment 2) When an area course is selected, massage is started within a predetermined treatment area range centering on the selected position. Further, when it is desired to change the treatment area range, the massager up / down switch is used to move the treatment element up / down to a desired position, and the area course is started at the position where the switch is released.

Next, when the position where the area course is selected is in the vicinity of the upper limit and the lower limit, the control is as follows. (1) Treatment is performed centering on the selected position until it is reversed by the upper limit or the lower limit. The non-inverted side is the distance in the normal area range. In this case, the upper limit or the lower limit position reaches the limiter and becomes short. (2) At positions where there is a possibility of reversal by the upper or lower limiter, the moving range is unified to match the repeat distance with other positions. That is, the lower limit or the upper limit position becomes shorter than usual.

Other application examples include the following forms. (Example 3) -When an area course is selected, massage is started in a predetermined area range centering on the position. After that, if the area course is continuously performed, the treatment area range is narrowed to continue the massage after a predetermined time has passed, and the treatment area range is further narrowed to continue the massage after the predetermined time has passed.

Further, in the fixed course (FIG. 5), the movement of the treatment element is stopped as indicated by 20 in FIG. 5, and seven kinds of treatments from the hitting to the widening are automatically and continuously performed on the spot. . By mixing various treatment patterns and performing the treatment in this way, the treatment pattern is achieved by first giving a beat to give the treatment, then giving a strong stimulus with a tap, then putting the chaff to finish with a wide strike at the end. ing.

In addition, in the treatment pattern on the fixed course,
It is also preferable to interlace treatment operations such as rolling operation and stretching operation that require vertical movement of the treatment element. In this case, the treatment element is moved while the treatment element moves from the arbitrary fixed position as a base point, and when the treatment operation pattern ends, the treatment element is returned to the original arbitrary designated position and the next treatment operation pattern is continued. .

The stretch means the following treatment (see FIG. 16). This is a treatment method that combines vertical movement of the treatment element and wide / narrow width (the narrower the width is slightly protruding), and is characterized by the combination of speed change and distance change compared to conventional moving fir. 16 shows an example of a stretch treatment trajectory used for a fixed automatic course.

As shown in FIG. 16, in the fixed automatic course, wide width → narrow width → wide width (or vice versa) is repeated continuously. In FIG. 16, for example, 71 and 72 indicate movements (trajectories) of the left and right treatment elements. 71 and 72 are 73 and 76
It starts from the starting point of and rises while narrowing the width between the treatment elements upward. Since the width becomes narrow when the ascending, the treatment element protrudes slightly forward and pushes the back of the user. If the treatment element does not move up and down and moves left and right, it will be a rubbing operation, but this stretch is a stretching operation in which the treatment element moves upward with a narrow movement of the treatment element, so that it protrudes while moving diagonally. . It should be noted that the movement from the narrow width to the wide width becomes a return locus in which the protruding state returns to the original state.

The loci of 71 and 72 end at 74 and 77,
It reverses and moves to the loci of 81 and 82, and ends at 75 and 78. Next, the loci of 83 and 84 are drawn, and after 85 and 86, the process returns to the initial start points 73 and 76. The loci of 83 and 84 are also a stretching operation in which the loci are projected while moving diagonally. -The time to move from wide to narrow and narrow to wide is set to be the same.

That is, in FIG. 16, each locus (7
1, 72, 81, 82, etc.) are set to the same time. Therefore, the longer the upper limit movement distance from the wide width to the narrower width is, the faster the speed is, and the stimulation is stronger, and the longer the upper limit movement distance from the narrow width to the wide width is, the weaker the stimulation feeling is. As described above, in FIG. 16, the time interval of each movement unit is set evenly. Therefore, FIG. 16A shows an example of a strong stretch treatment pattern, and FIG. 16B shows an example of a weak stretch treatment pattern. That is, in FIG.
The stretch motions 90, 91 and 92, 93 in (b) are treatments with weak stimulation because the treatment element moves slowly.・ In addition, in the fixed automatic course, it is possible to combine the rise and fall of the strength of the stretch. That is,
It is also possible to "strengthen when rising and weaken when falling".

[0051]

As described above, according to the present invention, when the user wants to relieve stiffness, the location of the stiffness is gradually narrowed from the surroundings, and finally the treatment is concentrated on a specific place. You can effectively localize and relieve stiffness.

Further, as described above, when it is desired to particularly relieve stiffness in a specific portion, the treatment element, that is, the massage unit, can be stopped at that portion and the treatment can be intensively performed, and an automatic course can be selected. Many treated users can also receive intensive treatment while the movement of the treatment element is stopped at such a specific location, and can relieve stiffness more effectively.
