Hereinafter, the movement trajectories of the contact portions 10a and 11a in the treatment arms 10 and 11 will be described. 10A and 10B are explanatory views showing the movement trajectories of the contact portions 10a and 11a. FIG. 10A is a rear view of the user, and FIG. 10B is a plan view of the user.
The contact portions 10a of the left and right first arms 10 move in a three-dimensional locus in the front-rear direction and the vertical direction while approaching and separating from each other in the left-right direction on the upper surface of the treatment portion (shoulder). Further, the contact portions 11a of the left and right second arms 11 move in a three-dimensional locus in the front-rear direction and the vertical direction while approaching and separating from each other in the left-right direction on the rear surface of the treatment portion (shoulder). . The movement of the contact portion 10a of the first arm 10 in the front-rear direction and the movement of the contact portion 11a of the second arm 11 in the front-rear direction are opposite to each other. Since the first arm 10 and the second arm 11 have different longitudinal dimensions and shapes, the movement trajectories of the contact portions 10a and 11a are also different.

  That is, when the contact portions 10a and 11a of the first and second arms 10 and 11 are close to each other, the treatment portion (shoulder) is sandwiched, and the contact portions 11a and 11a of the pair of left and right second arms 11 and 11 are sandwiched. As the two come close to and away from each other, the back of the treatment area (shoulder) is swung up and down. Since the contact portion 10a of the first arm 10 is located on the upper surface of the treatment portion (shoulder), it is possible to prevent the user's body from floating upward, and to squeeze up the contact portion 11a of the second arm 11 Can be carried out effectively. In addition, when the abutting portion 11a of the second arm 11 performs scooping, the abutting portion 10a of the first arm 10 is configured to move downward, so that scooping can be performed more effectively. When this treatment arm 3 is replaced with a hand, the contact portion 10a of the first arm 10 corresponds to the index finger to the little finger, and the contact portion 11a of the second arm 11 corresponds to the thumb. It is possible to realize a feeling.

Hereinafter, an example of the massage program which the massage machine 1 has will be described. FIG. 11 is a flowchart of the massage program (part 1). FIG. 12 is a flowchart of the massage program (part 2).
As shown in FIG. 11, when the user operates the operation unit 20 to start the massage program (part 1), the control unit 6 drives the motor 5 to rotate in the forward direction to pinch massage, massage up, or squeeze down by the treatment arm 3. Is started (step S1). Then, the motor 5 is continuously driven in the forward direction for a predetermined time, and the sandwiching massage, the squeaking up and the squeaking down by the treatment arm 3 are repeated. When the predetermined time has elapsed, the control unit 6 determines the close proximity positions of the first and second arms 10 and 11 by the position detection sensor 26 (step S2). When it is determined that the first and second arms 10 and 11 are in the close positions (for example, the closest positions), the control unit 6 stops driving the motor 5 (step S3). Subsequently, the control unit 6 excites the electromagnetic solenoid 27a to drive the hitting member 27 for a predetermined time, and after the predetermined time has elapsed, demagnetizes the electromagnetic solenoid 27a to stop the driving of the hitting member 27 (steps S4 to S6). Subsequently, the control unit 6 reversely drives the motor 5 to start pinching massage, squeaking up, and squeezing down by the treatment arm 3 (step S7).

  According to the massage program (part 1), since the hitting member 27 is driven when the first and second arms 10 and 11 are in the proximity positions, the hitting operation can be effectively given to the treatment site. . Further, since the hitting member 27 is driven in a state where the operations of the first and second arms 10 and 11 are stopped, the user can concentrate on the hitting operation and can fully feel the hitting operation.

  As shown in FIG. 12, when the user operates the operation unit 20 to start the massage program (part 2), the control unit 6 drives the motor 5 to rotate in the forward direction to pinch massage, massage up, or massage down by the treatment arm 3. Is started (step S8). Then, the motor 5 is continuously driven in the forward direction for a predetermined time, and the sandwiching massage, the squeaking up and the squeaking down by the treatment arm 3 are repeated. When the predetermined time elapses, the control unit 6 determines the proximity positions of the first and second arms 10 and 11 by the position detection sensor 26 (step S9). When it is determined that the first and second arms 10 and 11 are in the close position (for example, the closest position), the control unit 6 drives and controls the motor 5 so as to repeat normal rotation and reverse rotation in small increments ( Step S10).

  According to the massage program (part 2), the forward and reverse rotations of the motor 5 are repeated in small increments, so that the treatment portion can be quickly held and opened by the first and second arms 10 and 11. Further, the treatment portion can be quickly swung up and down by the pair of left and right treatment arms 3 and 3.
