Abstract: A massage machine is provided which is adapted to give a suitable massage in accordance with the degree of stiffness or degree of relaxation of the person to be massaged, based on the results obtained by measuring the body outline of the person and physiological data as to the person such as the pulse rate and skin temperature. The massage machine measures the body outline of the person, and measures physiological data concerning the person which is produced by massaging the person. The body outline of the person, such as the position of the neck, shoulder, back and waist is measured, and the measured physiological data is used to discriminate between the part of great stiffness and the part of low stiffness so as to give an effective massage in accordance with the degree of stiffness.

Abstract: A massage unit of a massage device moves upward and downward along a backrest of a chair. A pair of therapeutic arms are pivotably supported on a pair of pivot arms projecting forward when viewed from the backrest. Therapeutic fingers on the therapeutic arms have massage balls disposed on them. The pivot arms are driven to move the therapeutic arms in three dimensions, i.e., up and down, left and right, forward and back, so that a patient is massaged by the massage balls. An angle detector detects the angle of the therapeutic arms relative to the pivot arms. The magnitude and change in the output of the detector is used to determine the portion of the patient's body that is being contacted by the massage balls at any time.

Abstract: The present invention provides a massage machine comprising a living body information sensor 5 for detecting the living body information of the autonomic nervous system of the person to be massaged, and a control circuit 6 for controlling massage based on the living body information detected by the sensor 5. The control circuit 6 estimates the psychological state of the person based on variations in the living body information detected by the sensor 5, and adjusts massage movement in accordance with the estimated psychological state. In adjusting the massage movement, one of a relaxation mode and a refreshment mode can be selected, and the massage movement is so adjusted as to lower the activity of the autonomic nervous system in the relaxation mode, or is so adjusted as to increase the activity of the autonomic nervous system in the refreshment mode.
