An electric toothbrush includes an inner case, made up of an inner case main body and a motor holder, mounted with various components including a motor; an outer case which interiorly accommodates the inner case and which acts as a portion the user grips with hand when brushing teeth; an eccentric shaft, configured by a shaft main body and an eccentric member, which center of gravity is arranged at a position shifted from a shaft center and which rotates by a drive force of the motor; and a vibration transmitting component for transmitting the vibration generated with the rotation of the eccentric shaft to a brush portion; where the vibration transmitting component is positioned with respect to the outer case by point contacting the inner wall surface of the outer case at a plurality of locations.

Electric toothbrush

An electric toothbrush capable of suppressing loss of vibration energy while suppressing the vibration of the portion a user grips with hand is provided. In an electric toothbrush including an inner case, made up of an inner case main body and a motor holder, mounted with various components including a motor; an outer case which interiorly accommodates the inner case and which acts as a portion the user grips with hand when brushing teeth; an eccentric shaft, configured by a shaft main body and an eccentric member, which center of gravity is arranged at a position shifted from a shaft center and which rotates by a drive force of the motor; and a vibration transmitting component for transmitting the vibration generated with the rotation of the eccentric shaft to a brush portion; where the vibration transmitting component is positioned with respect to the outer case by point contacting the inner wall surface of the outer case at a plurality of locations.

An apparatus for measuring biological data such as blood pressure of a user has a pulse detector for simultaneously obtaining fingerprint data and a first signal from the user's body such as a pulse wave signal. The fingerprint data are used to check if the user is a registered user. After the user's biological data such as pulse waves are measured and a second signal is obtained from the user, the first and second signals are compared to check if this is the same user from whom the fingerprint data were taken in order to prevent the apparatus from being used by a wrong person. Comparison may be made between the first signal and a pattern of pulse waves extracted from earlier obtained pulse waves stored in a memory. Similar components may be used for an exercising machine to prevent it from being used by a person not preliminarily registered or a person different from the one who passed the fingerprint test on the machine.
