The photo diode 75 forms a photo coupler with the photo triac 67, and the photo diode 78 forms a photo coupler with the photo triac 70.

The operation of the rubbing machine 1 of this embodiment will be described below with reference to FIGS. The rubbing operation such as the kneading operation and the hitting operation in the rubbing machine 1 is as described above. In the rubbing machine 1 of the present embodiment,
a, 10b, at the end of the alternate beating operation,
The position of the subject 0b with respect to the patient can be determined at the same position by switching the rotation direction of the motor 60.

The output shaft 61 of the motor 60 rotates forward as an example,
That is, a case will be described in which the state in which the player is rotating clockwise in the direction of arrow A1 in FIG. FIG.
As shown in (1), when the alternate hit switch (not shown) of the remote controller 63 is operated, the microcomputer 72 of the remote controller 63 outputs a high-level forward rotation signal S shown in FIG. 73 conducts and a current flows through the photodiode 75 to emit light. As a result, the photo triac 67 becomes conductive, and the triac 66 is gated.
The triac 66 is turned on to supply a drive current to the motor 60. On the other hand, the reverse rotation signal G of the microcomputer 72 is at a low level as shown in FIG. 7C, the transistor 76 is kept off, the triac 69 is off, and the reverse drive current is supplied to the motor 60. Not done.

At this time, when the output shaft 61 of the motor 60 rotates clockwise (direction A1), the gear 39 turns counterclockwise, and the switching gear 40 rotates clockwise. At this time, since the screw portion 53 near the tip of the switching shaft 42 and the slide wheel 47 are engaged, the switching shaft 42 moves upward in FIG. 1, and the pin 46 contacts the contact piece 49, It rotates with the slide wheel 47. Also, since the switching shaft 42 moves to the upper end in FIG. 1, the detent pin 43 of the switching shaft 42 is disengaged from the engagement hole 57 of the switching gear 40, and the rotation of the gear cover 54 fixed to the switching gear 40 is stopped. It enters into the cut groove 54 ′ and engages with the gear cover 54. Also, the detent pin 44 of the switching shaft 42
Is in a state of being meshed with the switching gear 41,
The switching shaft 42 rotates with the rotation of the switch shaft 42, the switching gear 41 also rotates with the rotation of the switching shaft 42, and the gear 38 meshed with the switching gear 41 also rotates. That is, the gears 38 and 39 rotate together, and as shown in FIG.
The alternate beating operation by a and 10b is performed.

Next, as shown in FIG. 7 (1) to FIG. 7 (3), when the alternate hit switch is turned off, the forward rotation signal S becomes low level and the reverse rotation signal G becomes high level. Become. At this time, the transistor 76 is turned on and a current flows through the photodiode 78 to emit light. As a result, the photo triac 70 conducts, and the triac 69 is gated.
Signal is supplied, the triac 69 is turned on, and a driving current for reverse rotation is supplied to the motor 60. On the other hand, the forward rotation signal S of the microcomputer 72 is at a low level as shown in FIG. 7 (2), the transistor 73 is shut off, the triac 66 is also shut off, and the motor 60 is not supplied with the forward drive current.

When the motor 60 starts rotating counterclockwise (direction A1) from the clockwise state (direction A1), the gear 39 rotates clockwise and the switching gear 40 rotates counterclockwise. At this time, the switching shaft 42 moves downward in FIG. 1 while rotating while the screw portion 53 near the tip end thereof meshes with the screw 59 on the inner periphery of the slide wheel 47. Thus, the rotation preventing pin 43 moves downward in FIG. 1 while rotating counterclockwise in the cut groove 54 '. At this time, the detent pin 43
It moves from the inside of the gear cover 54 into the engagement hole 57 of the switching gear 40. Then, the detent pin 43 moved into the engagement hole 57 stops while the switching gear 40 makes a half turn, and during that time,
The rotation of the switching gear 40 is not transmitted to the switching shaft 42, and the switching gear 41 and the gear 38 stop rotating.

At this time, in the present embodiment, the switching shaft 42
The screw pitch between the screw portion 53 near the distal end and the screw 59 on the inner periphery of the slide wheel 47 is appropriately selected, and the rotation preventing pin 43 is engaged with the engagement hole of the switching gear 40 during the half rotation of the rotation shaft 27. 57 is rotated half a turn. Thereby, when the rotation shaft 27 makes a half rotation, the rotation preventing pin 43 engages with the switching gear 40. At this time, the circumferential position of the rotating shaft 26 is shifted by a half cycle as compared with the case where the motor 60 is in the clockwise state. Therefore, in the clockwise state of the motor 60, the massagers 10a and 10b perform an alternate beating operation. In the present case in which the motor 60 is rotated left, the massagers 10a and 10b Will be located at the same position.

As described above, when the switching shaft 42 moves downward in FIG. 1 and the detent pin 43 reaches the engagement hole 57 of the switching gear 40 and the motor 60 continues clockwise, the detent is stopped. The pin 43 presses the circumferential end of the engaging hole 57 to rotate the rotating shaft 42. The detent pin 44 fixed to the rotation shaft 42 also rotates the switching gear 41. As a result, the gear 38 also rotates, and the massagers 10a,
Simultaneous tapping operation by 10b is performed.

Thereafter, the beating operation shown in FIG.
In the case of performing the kneading operation shown in (3) or the above-described rolling operation, the pair of massaging members 10a and 10b, which were alternately operated in the hitting operation, are simultaneously operated only by switching the rotation direction of the motor 60. Can be switched as follows. Therefore, the hitting operation, the kneading operation, and the rolling operation can be performed using the pair of massagers 10a and 10b having the same position with respect to the patient. Thus, in the kneading operation, the treatment site can be effectively sandwiched between the pair of massaging elements 10a and 10b, and the lubrication effect can be improved. Further, even in the rolling operation, the positions of the pair of massagers 10a and 10b with respect to the patient are the same, so that the effect of stretching the back muscles can be improved.

On the other hand, when the movements of the massagers 10a and 10b are in the same phase, but are to be in the opposite phase,
That is, when the motor 60 switches from the counterclockwise state (A2 direction) to the clockwise state (A1 direction), the gear 39 rotates counterclockwise, and the switching gear 40 rotates clockwise. At this time, the rotation stop pin 43 is
After stopping in the engagement hole 57 and the rotation preventing pin 43 abutting on the terminal end of the engagement hole 57, the rotation starts together with the switching gear 40. Then, due to the meshing of the screw portion 53 near the tip of the switching shaft 42 and the screw 59 on the inner periphery of the slide wheel 47, the switching shaft 42 moves upward in FIG. 1 while rotating. This allows
The detent pin 43 rotates upward in FIG. 1 while rotating clockwise in the engagement hole 57 of the switching gear 40, and the detent pin 43 moves from the engagement hole 57 of the switching gear 40 It moves into the cut groove 54 'of the cover 54. As described above, after the rotation of the motor 60 is switched, the rotation is not transmitted from the switching gear 40 to the switching shaft 42 while the rotation preventing pin 43 is stopped, and the switching gear 41 and the gear 38 stop rotating.

At this time, when the rotation shaft 27 completes a half rotation by the selection of the screw pitch and the like between the screw portion 53 near the tip of the switching shaft 42 and the screw 59 on the inner periphery of the slide wheel 47 as described above. The positional relationship between the detent pin 43 and the switching gear 40 is shifted by a half turn, and the circumferential position of the rotary shaft 26 is shifted by a half cycle as compared with the counterclockwise state of the motor 60. In the counterclockwise state of the motor 60, the massagers 10a and 10b perform the simultaneous beating operation, so that in the current case where the motor 60 is rotated clockwise,
The massagers 10a and 10b perform alternate beating operations on the patient.

As described above, in the rubbing machine 1, the massager 10
In the case where the simultaneous operation of a and 10b is performed and the alternate operation is to be performed, the motor 60 is started and the rotating shaft 2 is rotated.
6. Rotate 6, 27 counterclockwise in FIG. Thereby, the massagers 10a and 10b perform an alternating operation. On the other hand, massager 10
When the simultaneous operation is to be performed from the state where the alternate operations a and 10b are being performed, the motor 60 is started to rotate the rotating shaft 2.
6. Rotate 6, 27 clockwise in FIG. Thereby, the massagers 10a and 10b operate simultaneously.

As described above, in the rubbing machine 1 of the present embodiment, the simultaneous operation and the alternate operation of the massagers 10a and 10b can be easily selected only by switching the rotation direction of the motor 60. Thereby, compared with the case of performing only one of the alternating operation and the simultaneous operation as in the related art, it is possible to realize various rubbing operations, increase the treatment effect, and significantly improve the operation quality. be able to.

The present invention is not limited to the above embodiments, but includes a wide range of modifications without departing from the spirit of the present invention.

[0033]

As described above, in the rubbing machine according to the first aspect of the present invention, the control means changes the rotational direction of the motor when the pair of massaging members performs the alternate beating operation performed on the patient. The direction of rotation is changed to the opposite direction. When the rotation direction of the motor is switched in the direction opposite to the rotation direction during the alternate tapping operation, the phase switching device causes the second rotation shaft to rotate by half a rotation thereof in the direction corresponding to the rotation direction after the switching of the motor. The rotation of the first rotating shaft is stopped over a period. Therefore, when the rotation direction of the motor is changed in the reverse direction, the first rotating shaft is stopped and the second rotating shaft is rotated by half a rotation thereof. The phase is switched to the same in the rotation direction.

Thus, in the massaging machine of the present invention, when the massaging operation of the massaging is a kneading operation or a rolling operation after the completion of the alternating striking operation, a pair of massaging operations which are alternately operated in the striking operation are performed. The child can be switched to operate simultaneously by simply switching the rotation direction of the motor. Therefore, the massaging operation and the rolling operation can be performed by using the pair of masses at the same position with respect to the patient. Thereby, in a fir operation | movement, a to-be-processed part can be pinched effectively by a pair of massagers, and a lubrication effect can be improved. In addition, even in the rolling operation, the positions of the pair of massagers with respect to the patient are the same, so that the back stretching effect can be improved.

The operation and effect of the present invention are as follows: the phase switching device comprises a first gear fixed to a first rotating shaft;
