<p>An improved body sensing device capable of precisely sensing a living body at a standstill by discriminating the living body from other substances than the living body. An oscillator (10) provided with a detection coil (11) oscillates a high frequency signal. As there is no object or exists baggage or the like near the detection coil (11), the oscillator (10) oscillates and generates a high frequency signal at a high level to be detected by a detector (20) for turning on a transistor (31) of a controller (30). As there exists a human body near the oscillator (10), the oscillation stops and the input signal from the detector (20) to the transistor (31) is extremely lowered, so that the transistor (31) is turned off. <IMAGE></p> |
