<P>PROBLEM TO BE SOLVED: To provide a detection apparatus that enables mounting of a piezoelectric sensor automatically so that a uniform connection state is achieved in every mounting operation. <P>SOLUTION: A detection apparatus 1 detects an object based on a change in oscillation frequency due to the object being adsorbed to an adsorption layer provided on an adsorption face of a piezoelectric vibrator 72 of a piezoelectric sensor 7. In the detection apparatus 1, a measuring device body 41 has a connection portion 412 to which the piezoelectric vibrator 72 is connected. The piezoelectric sensor 7 is detachably held by a holder 6, which is fitted to a moving body 212 allowing for up and down movement of play. A movement mechanism 2 allows the moving body 212 to move forward and backward between a hold position where the piezoelectric sensor 7 is held by the holder 6 and a connection position where the piezoelectric sensor 7 is mounted on the measuring device body 41. When the moving body 212 moves from the hold position to the connection position, the holder 6 is guided forward while being placed on a guiding component 42. <P>COPYRIGHT: (C)2012,JPO&INPIT |
