Abstract: A three-axis acceleration sensor is mounted to a body of an electric toothbrush. A CPU detects the three-dimensional attitude of the body based on an output from the acceleration sensor and, based on the attitude of the toothbrush, estimates which portion is being brushed. Then, the CPU performs control for switching between operation modes (such as the rotational direction of a motor and the frequency of vibration of the brush) according to the estimated portion being brushed.

Abstract: The invention provides an electric toothbrush capable of changing a resonant frequency and vibration amplitude of an eccentric shaft. An electric toothbrush of the present invention includes a motor, an eccentric shaft with one end fixed to a rotation shaft of the motor, and a stemserving as a vibration transmitting component having a bearing for supporting the other end of the eccentric shaft for transmitting vibration generated in accordance with rotation of the eccentric shaft to a brush portion. In the electric toothbrush, the eccentric shaft is formed so that a gravity center position is movable at least in one direction among a direction in which a distance to a shaft center is changed and an axial direction.

Abstract: A three-axis acceleration sensor is mounted to a body of an electric toothbrush. A CPU detects the three-dimensional attitude of the body based on an output from the acceleration sensor and, based on the attitude of the toothbrush, estimates which portion is being brushed. Then, the CPU measures by using a timer a brushing time of the portion being brushed. Results of brushing for each portion are evaluated and outputted based on the measured brushing time.

Abstract: A vibrator has massaging balls supported by a treating unit that may be shifted along a subject portion for treatment, guided by guiding members. The treating unit is supported by a supporting structure with respect to the guiding members. A position or orientation altering mechanism is provided for altering the position of the treatment unit in a direction orthogonal to the direction of its shifting or the orientation of the treating unit with respect to the guiding members. The supporting structure may include an engaging unit that engages the guiding members and an arm for supporting the engaging unit.

Abstract: A massaging machine includes a mechanism for oscillating its massaging unit and adjusting the protrusion of its massaging balls. The mechanism includes a bracket that supports the massaging unit, a supporting device by which the bracket supports the massaging unit by allowing the massaging unit to oscillate with respect to the bracket around a support axis parallel to the crank shaft of the massaging unit, a guiding member and a rotary driver such as a motor that drives the crank shaft rotationally. The guiding member has an elongated opening and a crank pin that engages in the elongated opening and serves to guide the crank pin to move with respect to the bracket perpendicularly to the direction of oscillation of the massaging unit and to the support axis.

Abstract: A massaging machine includes a massaging unit having massaging balls for contacting a patient and a massaging shaft that is rotationally driven and causes the massaging balls to undergo massaging motions and a lifting shaft that is rotated for moving the massaging unit along guide devices. Pinions are fixed to the lifting shaft and engage racks on the guide devices. Eccentric collars are supported by the lifting shaft and their outer peripheries support link holders rotatably. Arm-supporting members supporting the massaging balls are axially supported by the massaging shaft and are connected to the link holders. Phase difference in the rotary motions of the eccentric collars is varied by the direction of rotation of a motor for the eccentric collars.
