DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention
By the operation of the treated treatment element, the treatment applied to the treatment element
The treatment site is configured to perform treatments such as massage, tapping, and acupressure.
About massage machine. [0002] 2. Description of the Related Art In recent years, due to the growing health orientation,
Attention is being paid to massage machines used for home use
I have. In particular, treatment units that move along the back of the chair
A pair of knits projecting forward (front side of back)
Equipped with a treatment element, for movement of the treatment unit and movement of the treatment element
More various treatments to the treatment site pressed against the back
Chair-type massage for treatment (rubbing, tapping, acupressure, etc.)
From the neck line to the waist without changing the sitting posture
A wide range of treatments is possible, and excellent treatment effects are obtained.
It is widely used as a massage machine. [0003] Conventional massage machines of this type include
Although some species have already been proposed,
The current position of the treatment element is recognized as an absolute position.
And a reference position where the position of the treatment element is determined in advance.
There is a method of recognizing the position as a relative position to the position. [0004] In the former method, the power supply is switched off.
There is no need to select the reference position when the switch is turned on.
However, many position sensors (photo sensors) are required
Has the disadvantage of inviting cost increases, while
The treatment method is based on the treatment child each time the massage machine operates.
It is necessary to return to the position.
The operation is invalid, and during this return operation
Although there is an annoyance that you have to wait,
There is an advantage that it is simple and advantageous in cost. [0005] The present inventors have determined the position of the massage machine.
As a result of conducting experimental research on the recognition method, the latter method was used.
, Waiting time for the return movement of the treatment element to the reference position
Efficient use of can eliminate substantial waiting time
I knew that it would work. The present invention has been made based on such findings.
The aim is to move the treatment element to the reference position.
Enable the operation of the operation unit during the return movement process,
Make reservations for the next massage mode to use
Allows you to virtually eliminate waiting time and
A massage machine that can receive massage quickly
To offer. [0007] The massage according to the present invention
The machine is movably provided on the backrest,
A treatment element for executing a plurality of massage modes including
An operation unit for selecting and setting a massage mode by a massager,
When the power switch is turned on, the treatment element is moved to a predetermined reference position.
And a means for performing a return movement,
The operating section returns the treatment element to the reference position and moves it.
Reservation setting of massage mode is possible by operating while moving
It is characterized by the ability. [0008] According to the present invention, the treatment element is positioned at the reference position.
Use the time in the process of returning to the
By setting the reservation of the mode, the next massage can be done quickly.
It becomes possible to carry out, and handleability is improved. [0009] BRIEF DESCRIPTION OF THE DRAWINGS FIG.
It will be described in detail. FIG. 1 is an oblique view of a massage machine according to the present invention.

Down or down. By pushing up or down as described above,
The support arms 42, 42 correspond to the respective moving blocks 40, 40.
Around the axis of the support shaft 30 with the rotation of the arm holders 41, 41
Rocks. The operation of the acupressure drive shaft 33 is within a predetermined angle range.
Rotation at a low speed caused by
The swing of the holding arms 42, 42 occurs gradually in the same phase and is supported.
The treatment elements 4, 4 at the tips of the arms 42, 42 project forward.
Alternatively, the backward retreat operation is performed collectively. On the other hand, beating drive
The movement of the shaft 32 is a unidirectional rotation at a relatively high speed.
The swing of the support arms 42, 42 according to the rotation of the crank 3
2a and 32b alternately occur with a phase shift between
4 and 4 are in front and rear positions according to the rotational position of the acupressure drive shaft 33.
Make short-period up and down movements. Further, the massaging drive motor M₁Transmission from
When the massaging drive shaft 31 is driven to rotate, the treatment elements 4, 4
Depends on the sliding of the moving blocks 40, 40 that occur as described above.
To move toward or away from each other. Tapping drive shaft 32
The cranks 32a and 32b are suitably mounted on both sides of the center swing arm 34.
And the connecting links 43 and 44 to them
Is capable of swinging about the axis and sliding in the axial direction.
The approaching and separating movements of the treatment elements 4 and 4
 Allowed by sliding of connecting links 43 and 44 along 32a and 32b
