Abstract
An electronic clinical thermometer comprises a circuit for measuring and displaying the temperature of a portion being measured, a secondary battery for supplying electric power to the circuit, rectifier means connected to the secondary battery, a power receiving coil connected to the rectifier means for inducing a voltage in response to a change in an external magnetic field applied to the power receiving coil, and a hollow bar-shaped casing housing the circuit, the secondary battery, the rectifier means, and the power receiving coil. The secondary battery can be charged efficiently through the power receiving coil in response to the change in the external magnetic field. An apparatus for charging the electronic clinical thermometer comprises container means having a cylindrical cavity for accommodating a plurality of electronic clinical thermometers, a power transmitting coil disposed around the cylindrical cavity, and a.c. supply means for supplying an alternating current to the power transmitting coil, whereby the secondary battery can be charged by exciting the power receiving coil through inductive coupling between the power transmitting and receiving coils with the power transmitting coil positioned closely to the power receiving coil in the electronic clinical thermometer that is accommodated in the cylindrical cavity.
