Abstract

PURPOSE: To simplify the mechanism of a detection part for a body by allowing a control circuit to control and detect the vibration of a vibrating piece.
CONSTITUTION: Vibrating piece 1 has one terminal fixed and the other extended in contact with a body to be detected and near magnet 2 fixed to vibrating piece 1, detection coil 3 coupled electromagnetically with magnet 2 is arranged. While vibrating piece 1 comes partially in contact with some body, vibration shortens in attenuation time. For the purpose, the attenuation time of the free vibration of vibrating piece 1 is measured by control circuit 7, so that the existence of the body can be detected.
