[0001] This invention relates to a massage machine. Background Technology

[0002] Previously, a massage machine was proposed in which a massage device for massaging the treated area was built into the main body of the chair, and a massage tool that expands and contracts by supplying and exhausting air could be detachably installed (for example, see Patent Document 1).

[0003] Patent Document 1: Japanese Patent Application Publication No. 2004-201922 Summary of the Invention

[0004] In the massager described in the aforementioned Patent Document 1, for areas that cannot be massaged by the massager, massage is performed by wearing a massage tool wrapped around the arm or installed on the palm. However, there is a problem that the massage unit itself cannot be attached or detached according to the user's preference. Therefore, the present invention was made to solve the above-mentioned problems, and its object is to provide a massage machine in which the massage unit itself can be attached and detached according to the user's preference.

[0005] The massage machine of the present invention comprises: a massage unit for massaging the treatment area of ​​a user; a control unit for controlling the driving of the massage unit; and a storage unit for storing massage programs. The massage machine is characterized in that the massage unit is configured to be detachably mounted on a body support that supports the user's body, and the control unit changes the massage programs stored in the storage unit according to the mounting / detachment state of the massage unit mounted on the body support. By designing it in this way, the massage unit can be freely changed according to the user's preferences, and a massage program corresponding to the installed massage unit can be provided.

[0006] Furthermore, preferably, the body support portion has a mounting portion for mounting the massage unit, and the mounting portion is provided with a locking mechanism for fixing the massage unit to the body support portion. This design prevents the massage unit from falling off.

[0007] Furthermore, preferably, the massage unit is a massage unit that massages the same treatment area of ​​the user, and the massage unit has: a first massage unit; and a second massage unit, which is installed in place of the first massage unit by removing the first massage unit, and there are multiple second massage units. By designing the structure in this way, the second massage unit can be freely changed according to the user's preferences.

[0008] Furthermore, preferably, the control unit changes the massage program stored in the storage unit according to the second massage unit installed on the body support among the plurality of the second massage units. By configuring it in this way, it is possible to provide massage programs corresponding to the second massage units installed in the massage machine among multiple second massage units.

[0009] Furthermore, preferably, the body support portion is a seat for the user to sit on and a backrest for the user to lean against, and the second massage unit is detachably mounted on the seat and / or the backrest. By designing the structure in this way, the seat or backrest can be changed to suit the user's preferences.

[0010] Furthermore, preferably, the body support portion is an armrest portion that supports the user's arm, and the second massage unit is detachably mounted on the armrest portion. By designing the armrests in this way, they can be changed to suit the user's preferences.

[0011] Furthermore, preferably, the body support is a footrest that supports the user's legs, and the second massage unit is detachably mounted on the footrest. By setting it to this structure, the footrest can be changed to match the user's preferences.

[0015] [Overall structure of the massage machine] The overall structure of the massage machine 1 according to one embodiment of the present invention will be described below. Figure 1 This is a perspective view of a massage machine 1 according to one embodiment of the present invention. Figure 2 This is a block diagram of a massage machine 1 according to one embodiment of the present invention.

[0016] like Figure 1 , Figure 2 As shown, a massage machine 1 according to one embodiment of the present invention comprises a seat 3 for a user to sit on, a backrest 6 provided at the rear of the seat 3 for the user to lean against, a footrest 5 provided at the front of the seat 3, and an armrest 2 installed on the side of the seat 3. An arm massager 2a for massaging the user's arm is provided in the armrest 2. The massage machine 1 includes a massage unit M (massage mechanism 7, armrest unit 2, seat unit 3, side wall unit 4, footrest unit 5) for massaging the user, a control unit 8 for controlling the functions of the massage machine 1, a controller 9 for performing various operations on the massage machine 1, an air supply and exhaust device 11 for supplying and exhausting air to the airbags, and a drive unit (not shown) for swinging the footrest 5 or the backrest 6 in the back-and-forth direction. Each structure will be described later.

[0017] [Structure of the Control Department] Figure 2 This is a block diagram of a massage machine 1 according to one embodiment of the present invention. Figure 2 As shown, a control unit 8 is provided in the massage machine 1. This control unit 8 consists of a microcomputer or similar component used to control the driving of the massage units M (2A-5C, 7A-7C) or the air supply and exhaust device 11. This control unit 8 is located below the seat 3 (within the frame F). Figure 10 It is connected to the user-operated controller 9. Various massage actions are performed by the user operating the controller 9.

[0018] Furthermore, a storage unit 10 is connected to the control unit 8. Multiple massage programs P are stored in the storage unit 10. The control unit 8 can change the massage programs P stored in the storage unit 10 according to the installation / removal status of the massage unit M mounted on the body support S. The modification of the massage programs P will be described later. Furthermore, a sensor 12 is connected to the control unit 8. The sensor 12 is used to identify the type of each massage unit M installed on the massage machine 1. More specifically, a sensor (not shown) is installed on each massage unit M. Since the massage units M have different structures, the massage program P needs to be changed according to the structure of the installed massage unit M. Therefore, by reading the sensor (not shown) on the massage unit M side by the sensor 12 on the massage machine 1 side, the massage program P can be changed according to the installation / removal state of the massage unit M installed on the body support S (identifying the type of installed massage unit M). The change of program P based on sensor 12 will be described later.

[0019] [Structure of the air supply and exhaust system] like Figure 2 As shown, the air supply and exhaust device 11 consists of a pump 11a for supplying air to each unit 2A-5C, which is a massage unit composed of airbags, and a valve 11b connecting each unit 2A-5C to the pump 11a. By opening and closing the valve 11b, air can be supplied and exhausted to the airbags.

[0020] The massage unit M is used to massage the user's treatment area. More specifically, it is a massage unit M that massages the same treatment area of ​​the user. In this embodiment, the massage unit M has a first massage unit and a second massage unit. The part corresponding to the first massage unit will be described as unit 100 OA, and the parts corresponding to the second massage unit will be described as unit 200 OB and unit 300 OC. Furthermore, there can be multiple second massage units (in this embodiment, there are two units, unit 200 OB and unit 300 OC), and any number of units can be used. Therefore, the second massage unit can be freely changed according to the user's preferences.

[0021] Furthermore, by removing each massage unit M (described later) from the massage machine 1, it can be used as a single massage unit M (see reference). Figure 10 Therefore, even the massage unit M can be used as a single unit. For example, the armrest unit 2 can be used as a fixed (small) arm massager by using it as a single unit, or the footrest unit 5 can be used as a fixed (small) foot massager by using it as a single unit. That is, multiple users can receive massage simultaneously, including the user using massage machine 1 and the user using massage unit M which is not installed on massage machine 1 (removed from massage machine 1).

[0022] Furthermore, a massage unit M can be used with the massage mechanism or massage components removed from the massage unit M. For example, suppose there is a user who wants to use the armrest 2 for placing their arm but does not need arm massage. It is also possible to set up a massage unit M without a massage mechanism or massage components (only the frame of the armrest unit 2) to accommodate this situation. Even in this case, the control unit 8 can change the massage program P stored in the storage unit 10 (omit the block related to the drive of the armrest unit 2) according to the installation or removal status of the massage unit M installed on the body support unit S (here, the armrest unit 2). Details will be described later.

[0023] Figure 3 This is a front view of the armrest unit 2 according to one embodiment of the present invention. Figure 3 (a) is a diagram showing the first armrest unit 2A. Figure 3 (b) is a diagram showing the second armrest unit 2B. Figure 3 (c) is a diagram showing the third handrail unit 2C. The left and right sides of handrail unit 2 have the same structure, therefore... Figure 3 The description focuses on the right-side armrest units 2A to 2C, omitting the description of the left-side armrest units 2A to 2C. Furthermore, the arrangement of the armrest units 2 is an example and is not limited to this. For example, the openings of the armrest units 2 can be arranged to face upwards, or the openings of the armrest units 2 can be arranged to face outwards from each other.

[0024] [Structure of the armrest unit] like Figure 1 , Figure 10 As shown, armrest units 2A to 2C are detachably mounted on the upper surfaces of armrest bodies 2L and 2R. In this embodiment, the detachable nature of armrest units 2A to 2C relative to armrest bodies 2L and 2R is described, but this is only one example and is not a limitation. For example, the armrest units 2A to 2C could be an integral part of the armrest bodies 2L and 2R. The armrest units 2A to 2C and the armrest bodies 2L and 2R function as body support S (armrests) supporting the user's arms.

[0025] The armrest bodies 2L and 2R are mounted on the sides of the seat 3. More specifically, they are mounted on the frame F on which the seat 3 is mounted (see reference). Figure 10 ).like Figure 1As shown, a first armrest unit 2A, serving as a massage unit for massaging the user's arm (treatment area), is installed on the upper surface of the armrest body 2L, 2R. The first armrest unit 2A is detachable from the armrest body 2L, 2R (body support S) and can be changed (replaced) into a second armrest unit 2B or a third armrest unit 2C according to the user's preference.

[0026] like Figure 3 As shown in (a), the first armrest unit 2A has a mechanism for gripping and kneading the user's arm from above and below. The first armrest unit 2A is composed of multiple massage units. More specifically, the first armrest unit 2A is composed of a bottom wall 21, a side wall 22 extending upward from the right side of the bottom wall 21, and an upper wall 23 opposite to the bottom wall 21, forming a U-shape with an opening on the left (inner) side. Upper massage units 20UR and 20UL are mounted on the upper wall 23. Lower massage units 20DR and 20DL are mounted on the bottom wall 21. By inserting the user's arm into the opening, the user's arm can be massaged.

[0027] The upper massage units 20UR and 20UL are composed of multiple components. More specifically, they consist of a treatment element 24, a treatment plate 25 on which the treatment element 24 is mounted, a forward / backward mechanism 27 mounted on the upper surface of each treatment plate 25, and a force application mechanism 26. The upper massage units 20UR and 20UL are mounted symmetrically about the left and right sides with the swing axis 28 (connecting part 29) as the center.

[0028] The treatment element 24 is mounted on the lower surface of the treatment plate 25 (the surface opposite to the treated area). More specifically, it is mounted on the lower surface of the treatment plate 25 (the surface opposite to the treated area) and near the end of the treatment plate 25 (the end away from the swing axis 28). The treatment element 24 is made of an elastic component such as rubber or an elastomer. The treatment element 24 is formed in a hemispherical shape.

[0029] The shape of the treatment element 24 is an example, but not limited to it. For example, it can be formed into a cone shape. By changing the shape of the treatment element 24, the sensation of the massage applied to the user can be changed. Furthermore, the number of treatment elements 24 installed is also an example, but not limited to it. For example, multiple elements can be installed along the left-right direction, or multiple elements can be installed along the front-back direction. By changing the shape of the treatment element 24 or the number installed, the sensation of the massage applied to the user can be changed.

[0030] The treatment plate 25 is composed of plate-shaped components. A treatment element 24 for applying stimulation to the user is mounted on the lower surface of the treatment plate 25 (the surface opposite the treated area). A force-applying mechanism 26 for applying upward force to the treatment plate 25 is mounted on the upper surface of the treatment plate 25 (the surface opposite the upper wall 23). An airbag 27, serving as a forward and backward mechanism for pushing the treatment plate 25 downward, is installed between the treatment plate 25 and the upper wall 23.

[0031] The treatment plate 25 is mounted so as to swing freely in the vertical direction with the swing shaft 28 inserted into the connecting portion 29 as the fulcrum. More specifically, a pair of connecting portions 29 for connecting the treatment plates 25 are provided near the center of the lower surface of the upper wall 23. A connecting shaft 28 extending in the vertical direction is inserted into the center of the connecting portion 29. The end of the treatment plate 25 is mounted on the connecting shaft 28 inserted into the connecting portion 29. Therefore, when the forward and backward mechanism is driven, the treatment plate 25 is pushed downward with the connecting portion 29 (connecting shaft 28) as the fulcrum. When the treatment plate 25 is pushed downward, the treatment element 24 abuts against the treated area, thereby performing a massage. That is, the treatment plate 25 moves in the up and down direction (relative to the direction of moving closer to and further away from the treatment area) with the connecting part 29 as the fulcrum by driving the forward and backward mechanism (causing the airbag 27 to expand and contract).

[0032] The force-applying mechanism 26 applies force to the treatment plate 25 upwards (away from the treatment area). As an example, the force-applying mechanism 26 is made of an elastic spring. One end of the force-applying mechanism 26 is mounted on the upper wall 23, and the other end is mounted on the upper surface of the treatment plate 25UR. That is, the treatment plate 25 is always subjected to force in the direction toward the upper wall 23 (away from the treatment area) through the force application mechanism 26.

[0033] The retraction mechanism of the first armrest unit 2A is composed of an airbag 27 that expands and contracts by supplying and releasing air. By using the airbag 27 as the retraction mechanism, the upper massage sections 20UR and 20UL (treatment plate 25) can be moved forward and backward relative to the treated area in a direction of approach and distance with a simple structure. The retraction mechanism is mounted on the upper wall 23 that forms the opening. More specifically, it is mounted on a surface opposite to the upper surface of the treatment plate 25 and is designed to expand and contract with the connecting part 29 as the fulcrum. Furthermore, in this embodiment, the case where the forward and backward mechanism is composed of airbag 27 has been described, but this is only one example and is not limited thereto. For example, a structure using gears can be adopted.

[0034] If the retraction mechanism is activated (inflating the airbag 27), the treatment plate 25 moves downwards away from the upper wall 23, using the connecting portion 29 as a fulcrum. If the retraction mechanism is deactivated (contracting the airbag 27), the treatment plate 25 moves upwards towards the upper wall 23, using the connecting portion 29 as a fulcrum, through the action of the force application mechanism 26. Furthermore, the structures of the lower massage portions 20DR and 20DL are the same as those of the upper massage portions 20UR and 20UL, therefore, descriptions are omitted.

[0035] The control unit 8 can independently control the advance and retraction mechanisms (airbags 27) of each massage unit 20UR, 20UL, 20DR, and 20DL. For example, it can drive only the advance and retraction mechanism of the upper massage unit 20UR, or drive both the advance and retraction mechanisms of the upper massage unit 20UR and the lower massage unit 20DL. Furthermore, if the advance and retraction mechanisms located diagonally opposite each other are driven, massage can be performed by clamping the treatment unit diagonally from the top and bottom. Furthermore, the timing of actuating each of the advancing and retreating mechanisms can be the same or different. By making the actuation timing the same or having a time delay, a variety of massage techniques can be performed.

[0036] like Figure 3 As shown in (b), the second armrest unit 2B is a mechanism capable of pressing down on the user's arm from above and below. More specifically, with... Figure 3 (a) Similarly, the second armrest unit 2B is formed in a U-shape (bottom wall 21, side wall 22, upper wall 23). Airbags are installed on the upper surface of the bottom wall 21 (the surface opposite the user's arm) and the lower surface of the upper wall 23 (the surface opposite the user's arm). The airbags 27 in the second armrest unit 2B are massage airbags for massaging the user's arm. That is, although they are the same airbags, they perform a different function than the airbags 27 in the first armrest unit 2A. By inserting the user's arm into the U-shaped opening, the user's arm can be massaged. In addition, each airbag 27 is preferably capable of inflating and contracting independently.

[0037] like Figure 3 As shown in (c), the third armrest unit 2C is a mechanism capable of gripping and kneading the user's arms from both sides. The third armrest unit 2C is configured with a U-shaped opening facing upwards. Furthermore, in Figure 3 In (c), the diagrams of each wall are omitted. The third armrest unit 2C consists of a drive mechanism A having a rotating shaft G and treatment plates 22a mounted at both ends of the rotating shaft G. Airbags are mounted on the inner surface of the treatment plates 22a (the surface opposite the area being treated). The airbags 27 in the third armrest unit 2C are massage airbags used for massaging the user's arms. That is, although they are the same type of airbag, they perform a different function than the airbags 27 in the first armrest unit 2A. Furthermore, each airbag 27 is preferably capable of independently inflating and contracting.

[0038] An eccentric cam 22b is mounted on the underside of the treatment plate 22a. That is, the treatment plate 22a is mounted on the rotating shaft G with free swing via the eccentric cam 22b. Therefore, the treatment plate 22a swings in the up-down direction relative to the rotating shaft G via the eccentric cam 22b. Alternatively, an angular cam or an eccentric angular cam can be used instead of the eccentric cam 22b. When using an angular cam, the treatment plate 22a can swing in a direction closer to and further away from the treated area, enabling kneading motions on the user's arm. Furthermore, when using an eccentric angular cam, it is possible to combine the movement of the eccentric cam 22b with the movement of the angular cam.

[0039] Furthermore, in this embodiment, the first armrest unit 2A to the third armrest unit 2C are described as examples, but the structure of the armrest unit 2 is only one example and is not limited thereto. The massage unit can be of any structure if it can massage the user's arm. Furthermore, by detaching the armrest unit 2 from the massager 1, the armrest unit 2 can be used as a massage unit on its own. Additionally, a power supply device integrating the air supply and exhaust system is provided; by connecting the armrest unit 2 to this power supply device, the armrest unit 2 can be used as a massage unit on its own. Thus, it can be used as a single massage unit.

[0040] Figure 4 This is a front perspective view of the seat unit 3 according to one embodiment of the present invention. Figure 4 (a) is a diagram showing the first seat unit 3A. Figure 4 (b) is a diagram showing the second seat unit 3B. Figure 5 This is a front perspective view of the third base unit 3C according to one embodiment of the present invention. Figure 5 (a) is a diagram showing the state in which the seating part 30 is installed. Figure 5 (b) is a diagram showing the state of the seating section 30 being removed.

[0041] [Structure of the seat] like Figure 1 , Figure 4As shown in (a), the seat 3 (body support S, seat unit 3A) is composed of a rectangular component that extends horizontally in the left-right direction. The seat 3 is mounted on the frame F (reference). Figure 10 The upper surface of the seat 3, where the user sits, functions as a body support for the body. More specifically, the frame F can be easily installed and removed, and can be changed (replaced) with either the second seat unit 3B or the third seat unit 3C according to the user's preference. The structure of each seat unit 3A to 3C will be described later.

[0042] like Figure 4 As shown in (a), the first seat unit 3A consists of airbags 31 for pushing the user's buttocks upwards. More specifically, the first seat unit 3A consists of a seat body 30 including cushioning components such as urethane, and airbags 31 arranged in pairs on the upper surface of the seat body 30. Preferably, the airbags 31 can expand and contract independently, and by making the airbags 31 expand and contract independently, a variety of massages can be performed on the user's buttocks.

[0043] like Figure 4 As shown in (b), the second seat unit 3B is a mechanism capable of pushing the user's buttocks upwards from both the left and right sides. At least a portion of the mounting surface supporting the user's buttocks massages the area by pressing on a portion of the user's buttocks. The pressing direction of the second seat unit 3B is upwards. Furthermore, in this embodiment, the case of alternating left and right swinging up and down is described, but this is only one example and is not limited to this. For example, it can also be configured such that by providing drive mechanisms on the left and right sides respectively, it can swing left and right separately (swinging left and right simultaneously or with time delay, etc.).

[0044] The second seat unit 3B has a mounting surface 32 for supporting the user's buttocks. The mounting surface 32 is composed of a first surface 32a for supporting a first portion of the buttocks and a second surface 32b for supporting a second portion. The first surface 32b is located behind the second surface 32a. Therefore, if the buttocks are supported on the first surface 32b, the thighs are supported on the second surface 32a. By using the first surface 32b and the second surface 32a to form the mounting surface, it is possible to massage not only the buttocks but also the thighs.

[0045] The mounting surface 32 is formed by combining two surfaces: a mounting surface on the right side of the user's buttocks and a mounting surface on the left side of the user's buttocks. Each mounting surface can swing up and down alternately left and right by the action of the drive mechanism described later. The drive mechanism is composed of multiple components. It consists of a motor 36 as a power source, a rotating shaft 34 connected to the motor 36, and swing members 33 located at both ends of the rotating shaft. A worm gear 35 is located near the center of the rotating shaft 34. The worm gear 35 meshes with the output shaft of the motor 36. The swing member 33 has an eccentric cam with a left-right phase difference of 180 degrees.

[0046] If the motor 36 is rotated, the rotation of the motor 36 is transmitted to the rotating shaft 34 via the worm gear 35. The left and right phase difference of the swinging components 33 mounted at both ends of the rotating shaft 34 is 180 degrees, so when the left mounting surface swings upward, the right mounting surface swings downward. When the left mounting surface swings downward, the right mounting surface swings upward. Thus, an alternating upward and left-right massage can be performed on the user's buttocks.

[0047] like Figure 5 As shown, the seat unit 3C is a mechanism that allows the user's hips to swing from side to side. The seat unit 3C consists of a seat body 30 for the user to sit on and a swing mechanism J disposed on the lower side of the seat body 30. The seat body 30 is horizontal near the center and has a shape that rises upwards as it moves outwards in the left and right directions (see reference). Figure 5 (a) The seat body 30 is mounted to the swing mechanism J via movable members 38b having rollers 37 on the left and right sides. The seat body 30 swings in the left and right direction by driving the swing mechanism J.

[0048] like Figure 5 As shown in (b), the moving member 38b is a U-shaped plate-like member with an opening on its lower side, arranged in pairs front and back. The moving member 38b is cut open near its center, and each swinging member is located in the cut-open portion. Rollers 37 are mounted at both ends of the moving member 38b. By moving the rollers 37 on the plate 38a, the seat body 30 can swing in the left-right direction. On the outer surface of the moving member 38b in the front-back direction, grooves 39b are symmetrically arranged for engagement with pins 39a mounted on the plate 38a. The pins 39a and grooves 39b function as guides for guiding the movement direction of the seat body 30. That is, the moving part 38b swings by driving the swing mechanism J. At this time, since the movement of the moving part 38b is restricted by the guide (pin 39a and groove 39b), the moving part 38b moves in the left and right direction on the plate 38a. As the moving part 38b moves, the seat body 30 also moves in the left and right direction, which allows the user's buttocks to swing in the left and right direction.

[0049] The swing mechanism J is mounted on a plate 38a that is elongated in the left-right direction. The swing mechanism J comprises a motor 36 having a pulley 36a mounted on the front side of the plate 38a, a pulley 36b for transmitting the rotation of the motor 36 to the swing component, and a swing component (bearing 36d, plate 36c, eccentric cam 36f (including eccentric shaft 36e)) mounted on the rear side of the moving component 38b in the front-rear direction. Furthermore, corresponding pulleys (not shown) are also provided on the opposite sides of the pulley 36b and the eccentric shaft 36e. Belt components (not shown) are mounted throughout the pulleys 36a and 36b. Similarly, belt components (not shown) are also mounted on the pulleys (not shown) on the opposite side of the pulleys 36b and eccentric shaft 36e.

[0050] If motor 36 is rotated, pulley 36a rotates, and pulley 36b rotates via a belt component (not shown). At this time, the pulley (not shown) on the opposite side of pulley 36b is also rotated. Since a belt component (not shown) is mounted on the pulley (not shown), the pulley (not shown) on the opposite side of eccentric shaft 36e also rotates as the pulley (not shown) rotates. That is, the rotation of motor 36 is slowed down by multiple pulleys and transmitted to eccentric shaft 36e. As eccentric shaft 36e rotates, eccentric cam 36f rotates, and the moving part 38b mounted on eccentric cam 36f also moves.

[0051] The oscillating component is composed of multiple parts. An eccentric cam 36f (including an eccentric shaft 36e) is mounted on the rear side of the plate 38a in the front-rear direction. One end of the plate 36c is mounted on the eccentric shaft 36e. A bearing 36d is mounted on the other end of the plate 36c, and the moving part 38b is mounted via the bearing 36d. That is, the oscillating component is used to oscillate the moving part 38b relative to the plate 38a in the left-right direction. By driving the motor 36, the oscillating component oscillates, and the seat body 30 can be oscillated in the left-right direction via the moving part 38b.

[0052] [Backrest Structure] like Figure 1 As shown, the backrest 6 functions as a body support S that supports the upper body of the user by allowing them to lean against it. The backrest 6 is constructed of a rectangular component that extends along the height direction. A guide rail 16 is provided inside the backrest 6, and a massage mechanism 7 (massage unit M) is mounted via the guide rail 16. The front surface of the backrest 6 is covered by a cover member (not shown), and the massage mechanism 7, by moving up and down along the guide rail 16, can massage the back of the user's body (e.g., shoulders or waist) seated on the seat 3 via the cover member (not shown).

[0053] [Structure of sidewall unit] Figure 8 This is a diagram showing the sidewall unit 4 according to one embodiment of the present invention, viewed from the left. Figure 8 (a) is a diagram showing the second sidewall element 4B. Figure 8 (b) is a diagram showing the third sidewall unit 4C. The first side wall unit 4A has an airbag 41 installed on the inner side of the side wall in the left-right direction. Figure 10 ). And, as Figure 8 As shown in (a), the second sidewall unit 4B also has an airbag 41 installed on the inner side of the sidewall in the left-right direction. The difference between the first sidewall unit 4A and the second sidewall unit 4B is the structure of the sidewall on which the airbag is installed.

[0054] The first sidewall unit 4A is composed of a plate-shaped component that is elongated in the front-back direction, and an airbag 41 is installed on its inner side in the left-right direction. That is, massage can be performed by clamping the user's shoulder or upper arm from the left and right directions. The second sidewall unit 4B has an airbag 41 mounted on a rod-shaped frame 42 via a fastener 43. The frame 42 is constructed by bending in a way that elongates its length in the front-back direction, and the airbag 41 is mounted on its inner side in the left-right direction. That is, similar to the first sidewall unit 4A, massage can be performed by clamping the user's shoulder or upper arm from the left and right directions.

[0055] like Figure 8 As shown in (b), the third sidewall unit 4C not only has an airbag 41, but also a swing mechanism K. More specifically, the swing mechanism K consists of a motor 47, an eccentric cam 46 mounted on the motor 47, and a plate 42 mounted on the eccentric cam 46. The eccentric cam 46 has a rotation shaft 45 that serves as the center of rotation and an eccentric shaft 44 that is eccentrically positioned relative to the rotation shaft 45. The airbag 41 is mounted on the inner side of the plate 42 in the left-right direction.

[0056] Plate 42 is eccentrically mounted to motor 47 via eccentric cam 46, so if motor 47 is driven, it will rotate in the up-down and back-and-forth directions. That is, in addition to the monotonous massage action of the airbag 41 clamping the user's shoulder or upper arm from the left and right directions, the massage action can also be varied by swinging it in the up-down and back-and-forth directions through the action of the swing mechanism K.

[0057] Figure 6 This is a diagram illustrating the footrest unit 5 according to one embodiment of the present invention. Figure 6 (a) is a front perspective view of the second footplate unit 5B. Figure 6 (b) is a top view showing the foot massage section 500 of the second footrest unit 5B. Figure 7This is a front perspective view showing the footboard unit 5 (third footboard unit 5C) according to one embodiment of the present invention. Also, refer to... Figure 1 The first footplate unit 5A will be described. Furthermore, in this embodiment, the footrest 5 is described as a massage unit M as a whole, thus allowing each footrest unit 5A to 5C to be attached and detached from the massage machine 1. However, for example, the frame 51 can be kept as is, and only the rollers 52b, including the foot massage section 500 of the second footrest unit 5B and the drive mechanism of the third footrest unit 5C, can be detachably assembled. Therefore, the footrest 5 can be changed to correspond to the user's preferences.

[0058] [Structure of the footboard] like Figure 1 As shown, the first footrest unit 5A includes leg massage airbags 53 for massaging the user's legs. More specifically, in the frame 51 constituting the first footrest 5A, recesses 5b into which the user's legs can be inserted are arranged symmetrically on both sides. Airbags 53 for massaging the user's legs are respectively provided on the inner walls of the left and right sides of the recesses 5b. The footrest 5, which supports the user's legs, functions as a body support S. More specifically, one airbag 53, serving as a leg massager, is provided on each of the inner walls of the left and right sides of the right recess 5b, and one airbag 53 is provided on each of the inner walls of the left and right sides of the left recess 5b. Each airbag 53 is preferably configured to expand and contract independently. Furthermore, a foot massager (not shown) for massaging the user's feet may also be provided on the bottom surface of the recess 5b.

[0059] like Figure 6 As shown in (a) and (b), in addition to the airbags 53 installed on the inner walls of the left and right outer sides of the left and right recesses 5b, the second footplate unit 5B also has a foot massage part 500. The foot massage part 500 is composed of multiple components. Furthermore, the foot massage unit 500 is symmetrical about the drive mechanism 55, therefore, the description of the left foot massage unit 500L will be provided, while the description and reference numerals for the right foot massage unit 500R will be omitted. Regarding the structure of the foot massage unit 500R, the L appearing in the description of the foot massage unit 500L will be replaced with R.

[0060] The foot massage unit 500 consists of a right foot massage unit 500R for massaging the user's right foot and a left foot massage unit 500L for massaging the user's left foot. Each foot massage unit 500L and 500R is mounted on the output shaft 56 via an angled portion (angled cam 58cL). Hereinafter, the foot massage unit 500L will be described as an example.

[0061] The foot massage unit 500L consists of a foot support unit 59cL (including a treatment component 59aL and an air bladder 59bL), toe units 58aL to 58dL, and heel units 57aL to 57cL. The toe unit is composed of multiple components. More specifically, it comprises an L-shaped foot support 59cL placed on the sole of the foot, a pair of treatment elements 59aL arranged back-to-back on the bottom side of the foot support 59cL, and an airbag 59bL disposed on the side side of the foot support 59cL. A support member 58dL is located on the underside of the foot support 59cL, and an angled cam 58cL is mounted on the support member 58dL. A receiving portion 58bL is located at the rear of the support member 58dL.

[0062] The heel units 57aL to 57cL consist of a heel support 57aL for mounting the heel, a shaft support 57bL mounted in front of the heel support 57aL, and a swing shaft 57cL mounted on the shaft support 57bL. A connecting rod 58aL is mounted on the swing shaft 57cL. The connecting rod 58aL is inserted into a receiving portion 58bL located behind the support member 58dL.

[0063] If the output shaft 56 is rotated, the foot support portion 59cL will swing left and right through the action of the eccentric cam 58cL, thus massaging the user's feet. Alternatively, an eccentric cam can be used instead of the eccentric cam 58cL. When using an eccentric cam, the foot support portion 59cL swings up and down, massaging the user's feet. Furthermore, an eccentric eccentric cam can also be used. When using an eccentric eccentric cam, the foot support portion 59cL swings not only up and down but also left and right, enabling a three-dimensional massage of the user's feet.

[0064] like Figure 7 As shown, the third footrest unit 5C is a footrest equipped with a roller 52b that massages the user's feet. The third footrest 5C consists of a frame 51 with a recess for supporting the foot, a rack 51a disposed in the frame 51, a pinion 52a meshing with the rack 51a, and a roller 52b. The roller 52b is a polygon with its corners removed, and is driven by a drive mechanism (not shown) disposed in the frame 51 to massage the user's feet while rotating.

[0065] Roller 52b is mounted on a rotating shaft (not shown) that is inserted into a drive mechanism (not shown). Pinion gears 52a are mounted at both ends of the rotating shaft (not shown). When the rotating shaft (not shown) rotates, the pinion gears 52a move along the rack 51a provided on the frame 51 in the back-and-forth direction. That is, the third footrest unit 5C is not a simple roller, but can massage the user's feet while moving in the front and back direction.

[0066] [Massage parlor] Figure 9 This is a diagram illustrating a massage mechanism 7 according to one embodiment of the present invention. Figure 9 (a) is a front perspective view of the first massage unit 7A. Figure 9 (b) is a frontal perspective view of the treatment arm of the second massage unit 7B. Figure 9 (c) is a diagram showing the treatment arm of the third massage unit 7C as viewed from the left. Additionally, Figure 9 (a)~ Figure 9 The structural differences between the massage mechanisms 7 in (c) are the number of treatment elements 70 and the shape of the arms 71 supporting the treatment elements 70. Therefore, the structure of the drive mechanism, etc., used to actuate the treatment elements 70, which are common structures, will be described using the first massage mechanism 7A as an example, and its description will be omitted in the descriptions of the second massage mechanism 7B and the third massage mechanism 7C. In addition, the structure of each massage mechanism 7 is only one example and is not limited to this.

[0067] like Figure 9 As shown in (a), the first massage mechanism 7A is composed of multiple components. More specifically, the first massage mechanism 7A consists of a treatment element 70, a main body consisting of an arm 71 supporting the treatment element 70 and a drive mechanism V (including a reducer 73, etc.) on which the arm 71 is mounted, and a frame 75 on which the main body is mounted.

[0068] The frame 75 is configured as a roughly quadrilateral shape, with the top, bottom, left, and right sides of a metal plate bent forward, forming a cavity on the inside. The main body of the first massage mechanism 7A is installed in this cavity. Small gears 76 are installed on the left and right sides of the frame 75 to allow the first massage mechanism 7A to move vertically along the guide rail 16 on the backrest 6. Anti-dislodgement tools 77 are installed on the outer sides of the small gears 76 in the left and right directions to prevent them from falling off. The upper small gear 76 is mounted at both ends of a rotating shaft 74 that passes through the reducer 73. The lower small gear 76 is mounted on the frame 75 via a rotating shaft 78 and is capable of free rotation.

[0069] If the motor (not shown) installed in the reducer 73 is driven, the rotating shaft 74 inserted into the reducer 73 will rotate. Along with the rotation of the rotating shaft 74, the upper pinion 76 also rotates, and the first massage mechanism 7A moves vertically along the guide rail 16. The drive mechanism V has a built-in motor (not shown) for rotating the kneading shaft or the tapping shaft. By rotating the motor (not shown), the treatment piece 70 can perform kneading massage or tapping massage.

[0070] like Figure 9 As shown in (b), the second massage mechanism 7B is a massage mechanism in which the arm 71 is configured as two strands, one vertical and one horizontal. The arm 71 is configured as two strands, one vertical and one horizontal, extending from the rear to the front. A limiting part 71d for limiting the swing of the arm 71 is installed on the rear end side of the arm 71. The limiting part 71d is installed on the frame 75 of the massage mechanism 7. The vertical swing of the arm 71 is limited by the limiting part 71d, so if the drive mechanism V is driven, the arm 71 swings in the left-right direction.

[0071] Treatment elements 70 are mounted on the upper and lower sides of the arm 71, respectively. Each treatment element 70 consists of two ball bearings (four ball bearings in total, one on the upper side and one on the lower side, 70a). A hole is formed near the center of the arm 71. An eccentric cam 72 is mounted in this hole, separated by a bearing. The eccentric cam 72 is mounted on a kneading shaft (not shown) that constitutes the drive mechanism V. Therefore, when the drive mechanism V is activated, the kneading shaft (not shown) rotates, and the eccentric cam 72 mounted on the kneading shaft (not shown) rotates as well. Through the action of the eccentric cam 72 and the limiting part 71d, the rotational motion of the kneading shaft (not shown) is converted into the oscillating motion of the treatment elements 70a and 70b, enabling a kneading massage action to be performed on the user.

[0072] like Figure 9 As shown in (c), the third massage mechanism 7C is a massage mechanism in which the arm 71 is divided into two parts and a forward / backward mechanism 71c is provided between the two parts of the arm 71. The arm 71 is composed of a first arm 71a located on the front side and a second arm 71b located on the rear side, and the first arm 71a and the second arm 71b are mounted via a swing shaft T. An airbag 71c, which serves as a forward / backward mechanism for swinging the first arm 71a relative to the second arm 71b, is mounted on the front surface of the second arm 71b (the surface opposite to the back surface of the first arm 71a).

[0073] The treatment element 70 consists of two rollers (four rollers in total, one on the upper side and one on the lower side, 70a and 70b). Each of the treatment elements 70a and 70b is mounted above and below the first arm 71a located on the front side. When the airbag 71c is inflated, the first arm 71a is pushed forward (towards the user) with the swing axis T as its fulcrum. This pushing of the first arm 71a allows the treatment element 70a to fit more closely to the user, thus providing a powerful massage.

[0074] The second arm 71b is fitted with the third arm 72a via a swing shaft 72c. More specifically, the swing shaft 72c is mounted near the center of the second arm 71b, and a force-applying mechanism is mounted along the lower sides of both the second arm 71b and the third arm 72a. The force-applying mechanism is a spring 72b. The second arm 71b is constantly subjected to force by the force-applying mechanism (spring 72b), causing the upper side of the second arm 71b to tilt forward. This allows massage to be performed along the user's treatment area by the treatment pieces 70a and 70b.

[0075] Near the center of the third arm 72c, an eccentric cam 72 is mounted via a bearing. The eccentric cam 72 is mounted on the kneading shaft (not shown) that constitutes the drive mechanism V. Therefore, when the drive mechanism V is driven, the kneading shaft (not shown) rotates, and the eccentric cam 72 mounted on the kneading shaft (not shown) rotates as well. The eccentric cam 72 converts the rotational motion of the kneading shaft (not shown) into the oscillating motion of the treatment pieces 70a and 70b, enabling kneading massage movements to be performed on the user.

[0076] [Lockdown Agency] Figure 11 This is a diagram representing the locking mechanism. Figure 11 (a) is a diagram representing the locked state. Figure 11 (b) is a diagram representing the state where the lock has been released. Figure 11 (c) indicates that in Figure 11 The diagram shows the state in which the massage unit M is installed on the body support S. The locking mechanism is an example, but not limited to it. The locking mechanism is used to secure the massage unit M to the body support S. When each massage unit M is installed on the massage machine 1, any mechanism can be used to lock the massage unit M in place so that it will not fall off.

[0077] like Figure 11 As shown, the locking mechanism is composed of multiple components. The locking mechanism is disposed on the mounting portion Q for mounting the massage unit M. In this embodiment, the mounting portion Q and the locking mechanism are integrally formed. The mounting portion Q consists of a main body portion 91 having a recess 92 and a locking mechanism disposed on the main body portion 91. The locking mechanism consists of a switching portion 93 for switching between a locked state and a locked-out state and a locking pin 94.

[0078] By rotating the switching unit 93 by 90 degrees, the locked state and the unlocked state can be switched. The locked state refers to the state in which the handle 93a of the switching unit 93 is rotated 90 degrees from a horizontal position to a vertical position (see reference). Figure 11(a)). If the handle 93a of the switching unit 93 is rotated 90 degrees, the locking pin 94 pops out from the main body 91 according to the rotation of the handle 93a. The popped-out part is inserted into the groove 96 of the pin 95 provided on the body support part S or the massage unit M side. Therefore, the massage unit M can be locked in place so that it will not fall off the massager 1.

[0079] The unlocked state refers to the state in which the handle 93a of the switching unit 93 is horizontal by rotating it 90 degrees from a vertical position (see reference). Figure 11 (b) If the handle 93a of the switching unit 93 is rotated 90 degrees, the locking pin 94, which pops out according to the rotation of the handle 93a, retracts into the main body 91. By retracting the locking pin 94 into the main body 91, the insertion of the pin 95 provided on the body support S or the massage unit M side is eliminated, and the massage unit M can be removed from the massage machine 1.

[0080] The mounting part Q is installed on the side or bottom of the massage unit M. For example, if it is the seat unit 3 or the armrest unit 2, it is installed on the bottom; if it is the side wall unit 4, it is installed on the side. The installation is done according to the shape of the massage unit M. The massage unit M is installed on the body support S (seat 3, backrest 6, etc.) via the mounting part Q. The mounting part Q can be installed on the side of the body support S or on the side of the massage unit M.

[0081] like Figure 11 As shown in (c), the massage unit M (armrest unit 2) is shown installed on the body support S (armrest body 2R). More specifically, the mounting part Q is integrally formed with the armrest unit 2 (massage unit M), and a pin 95 is provided on the body support S side. Alternatively, the mounting part Q can be provided on the body support S (armrest body 2R) side, and the pin 95 can be provided on the armrest unit 2 (massage unit M) side. In short, it is acceptable as long as the massage unit M can be installed on the body support S via the mounting part Q.

[0082] A pin 95 for inserting a mounting part Q is mounted on the upper surface of the armrest body 2R (body support part S). A groove 96 for engaging a locking pin 94 is provided at the end of the pin 95. By inserting the recess 92 of the mounting part Q, which is integrally formed in the armrest unit 2, into the pin 95 provided on the upper surface of the armrest body 2R, the user can easily install and remove the massage unit M (armrest unit 2).

[0083] [Changes to the massage procedure] Figure 12This diagram illustrates the changes to the massage program P corresponding to the massage unit M. Multiple massage programs P1, P2, ... are stored in the storage unit 10. The control unit 8 changes the massage program P stored in the storage unit 10 in accordance with the massage units mounted on the body support S in the first massage unit and the multiple second massage units. In this embodiment, the changes to the massage program P1 will be explained using massage program P1 as an example. like Figure 12 As shown, massage program P1 is a "full body massage process" that massages the user's entire body. The full body massage process is composed of a combination of multiple blocks B1 to B8. At this time, the massage unit installed on the massage machine 1 is configured as the second armrest unit 2B, the first seat unit 3A, the first side wall unit 4A, and the first footrest unit 5A.

[0084] At this point, it is assumed that each massage unit M is equipped with a sensor (not shown) corresponding to that massage unit M. More specifically, sensors 2Aa to 2Ca (not shown) are installed in the first armrest unit 2A to the third armrest unit 2C, sensors 3Aa to 3Ca (not shown) are installed in the first seat unit 3A to the third seat unit 3C, sensors 4Aa to 4Ca (not shown) are installed in the first side wall unit 4A to the third side wall unit 4C, and sensors 5Aa to 5Ca are installed in the first footrest unit 5A to the third footrest unit 5C.

[0085] The user removes the first seat unit 3A (sensor 3Aa) and the first side wall unit 4A (sensor 4Aa) from the massager 1, and installs the third seat unit 3C (sensor 3Ca) and the third side wall unit 4C (sensor 4Ca) onto the massager 1. The control unit 8 identifies the type of massage unit M installed on the massager 1. More specifically, the sensor 12 installed on the massager 1 reads the sensors of the third seat unit 3C (sensor 3Ca) and the third side wall unit 4C (sensor 4Ca) to identify the type of massage unit M installed. If the identification is successful, the control unit 8 begins to change the massage program P1 stored in the storage unit 10 according to the installation / removal status of the massage unit M installed on the massage machine 1. More specifically, the operation content of multiple blocks B1 to B8 is changed.

[0086] The first seat unit 3A has a pair of airbags 31 mounted on the left and right sides of the seat body 30, and the third seat unit 3C has a swing mechanism V on the lower side of the seat body 30 for swinging the seat body 30 in the left and right direction. That is, by replacing the first seat unit 3A with the third seat unit 3C, the user can be massaged based on the seat swaying, instead of the pressing of the airbags 31.

[0087] The movement of the first seat unit 3A is defined as movement block B2. Movement block B2 is the alternating and repetitive movement of inflating and contracting the right airbag 31 and the left airbag 31. The movement of the third seat unit 3C is defined as movement block B2a. Movement block B2a is the movement that causes the seat body 30 to swing left and right.

[0088] If the first seat unit 3A is replaced with the third seat unit 3C, the sensor 12 installed on the massager 1 detects the interruption of the response from the sensor 3Aa in the first seat unit 3A and the response from the sensor 3Ca in the third seat unit 3C. In this case, the control unit 8 reads the sensor 3Ca and receives the massage program stored in the third seat unit 3C. Since the airbag 31 is not installed on the third seat unit 3C, the action block B2 cannot be executed. The control unit 8 determines that it is necessary to change the massage program P1 (action block B2) stored in the storage unit 10.

[0089] Control unit 8 changes action block B2 to action block B2a. More specifically, it deletes action block B2 and retrieves action block B2a corresponding to the action of the third unit 3C from storage unit 13. The retrieved action block B2a is then inserted in place of the deleted action block B2. Therefore, while changing the action content of the massage program P1, the user can be massaged based on the seat rocking through the action block B2a.

[0090] The first sidewall unit 4A has a pair of airbags 41 mounted on the left and right sides of the sidewall body 40. The third sidewall unit 4C has a swing mechanism K for swinging the entire third sidewall unit 4C about a rotation axis 45 in the up-down and back-and-forth directions. That is, by replacing the first sidewall unit 4A with the third sidewall unit 4C, a massage based on the pressure of the airbags 41 and the swing of the third sidewall unit 4C can be performed on the user.

[0091] The operation of the first sidewall unit 4A is defined as action block B4. Action block B4 is the action that causes the airbags 41 installed on the left and right sides of the first sidewall unit 4A to inflate simultaneously. The operation of the third sidewall unit 4C is defined as action block B4a. Action block B4a is the action of the swing mechanism K that causes the first sidewall unit 4A and the left side of the first sidewall unit 4A to swing in the same direction of rotation.

[0092] If the first sidewall unit 4A is replaced with the third sidewall unit 4C, the sensor 12 installed in the massager 1 detects the interruption of the response from the sensor 4Aa of the first sidewall unit 4A and the response from the third sidewall unit 4C (sensor 4Ca). In this way, the control unit 8 reads the sensor 4Ca and receives the massage program stored in the third sidewall unit 4C. The third sidewall unit 4C is capable of performing a swinging motion based on the swinging mechanism K, which is not present in the first sidewall unit 4A. Therefore, the motion block B4 cannot correspond to the swinging motion of the third sidewall unit 4C (execute the swinging motion). The control unit 8 determines that it is necessary to change the massage program P1 (motion block B4) stored in the storage unit 10.

[0093] Control unit 8 changes action block B4 to action block B4a. More specifically, it deletes action block B4 and retrieves action block B4a corresponding to the action of the third side wall unit 4C from storage unit 10. The retrieved action block B4a is then inserted in place of the deleted action block B4. Thus, while changing the action content of the massage program P1, the user can be massaged based on the oscillation of the side wall unit through the action block B4a.

[0094] like Figure 12 As shown, the massage program P1 is configured to execute action blocks B2 to B8 sequentially from action block B1. However, since the massage unit M is replaced, the action content of the action blocks needs to be changed. In summary, in Figure 12 In this process, by setting action block B2 as action block B2a and action block B4 as action block B4a, massage program P1 automatically changes to massage program P2. The change in massage program P is further optimized based on the recognition (reading) from sensors (not shown) installed in each massage unit M. That is, even with the same full-body massage process (massage program P), the actions of massage program P are changed according to the installation and removal status of the massage unit M and provided to the user.

[0095] The modification of massage program P1 when the fourth armrest unit 2D (sensor 2Da) of the massage mechanism or massage component is removed from the massage unit M and installed on the massage machine 1 is explained (see reference). Figure 12 (a)(d)). The user removes the first armrest unit 2A (sensor 2Aa) from the massager 1 and installs the fourth armrest unit 2D (sensor 2Da) onto the massager 1. The control unit 8 identifies the type of massage unit M installed on the massager 1. More specifically, it reads the sensor of the fourth armrest unit 2D (sensor 2Da) using the sensor 12 installed on the massager 1 and identifies the type of massage unit M installed. If the identification is complete, the control unit 8 starts changing the massage program P1 stored in the storage unit 10 according to the installation / removal status of the massage unit M installed on the massager 1. More specifically, it changes the operation content of multiple blocks B1 to B8.

[0096] If the first armrest unit 2A is replaced with the fourth armrest unit 2D, the sensor 12 installed in the massager 1 detects the interruption of the response from sensor 2Aa in the first armrest unit 2A and the response from sensor 2Da in the fourth armrest unit 2D. The control unit 8 then reads sensor 2Da. Since no massage mechanism or massage component is provided in the fourth armrest unit 2D, no massage is performed on the user. The operation of the first armrest unit 2A is defined as action blocks B3 and B5. If the first armrest unit 2A is replaced with the fourth armrest unit 2D, since no massage mechanism or massage component is provided in the fourth armrest unit 2D, action blocks B3 and B5 cannot be executed. If the control unit 8 recognizes that the first armrest unit 2A has been removed from the massager 1 and the fourth armrest unit 2D has been installed, it determines that the massage program P1 (action blocks B3 and B5) stored in the storage unit 10 needs to be changed.

[0097] Control unit 8 omits action blocks B3 and B5. More specifically, action block B3 is deleted, and the content of massage program P is changed so that action block B4 is executed after action block B2. Furthermore, action block B5 is deleted, and the content of massage program P is changed so that action block B6 is executed after action block B4. That is, the operation content of the massage program P1 can be changed according to the installation and removal status of the installed massage unit M. The changed massage program P becomes massage program P3 and is executed by the control unit 8.

[0098] In this embodiment, the case where armrest units 2A to 2D are mounted on the upper surface of armrest bodies 2L and 2R is described. However, it is also possible not to mount armrest units 2A to 2D on armrest bodies 2L and 2R. For example, if pins 95 are provided on the upper surface of armrest bodies 2L and 2R, the pins 95 are accommodated inside the armrest bodies 2L and 2R, and the holes accommodating the pins 95 are covered when the upper surfaces of the armrest bodies 2L and 2R are coplanar. If the sensor detects (identifies) that the holes are covered, it can be determined, similar to the case where the fourth armrest unit 2D is mounted, that the massage program P1 (action blocks B3 and B5) stored in the storage unit 10 needs to be changed.

[0099] Furthermore, a foldable pin 95 is provided on the upper surface of the armrest body 2L, 2R. By folding the pin 95, it is housed inside the armrest body 2L, 2R. With the upper surfaces of the armrest body 2L, 2R becoming a flat plane, the groove housing the pin 95 is covered. If the sensor detects (identifies) that the groove is covered, it can be determined, similar to the case where the fourth armrest unit 2D is installed, that the massage program P1 (action blocks B3, B5) stored in the storage unit 10 needs to be changed.

[0100] The arrangement of action blocks B1 to B8 is an example, but not limited to this. For example, massage program P could be performed before action block B2. The combination (execution order) of action blocks B1 to B8 can be appropriately modified according to the content of massage program P. In addition, action blocks other than action blocks B1 to B8 (e.g., action block B9) can be added. Therefore, the massage unit M can be freely changed according to the user's preferences, and the massage machine 1 can provide the user with a massage program P corresponding to the installed massage unit M.
