PURPOSE:To eliminate the wasteful consumption of a battery at the time of non-use, by increasing the magnetic field formed by a high frequency generating circuit and an antenna when the title apparatus is mounted on the body. CONSTITUTION:A temp. detection circuit 9 is provided to an oscillation circuit 6 and controls the oscillation circuit 6 to control the output of a current to an antenna 7. A thermistor RTH detects the temp. based on bodily temp. when a unit case is mounted on a mount region and, on the basis of the detection output thereof, the current flowing to an inductance through a transistor Q1 is increased. By this method, the electromagnetic field from the antenna 7 is strongly emitted in a degree necessary for promoting blood circulation. |
