Contact survey instrument and its contact inspection method of contact survey instrument and disk unit

摘要

To body of revolution, it loads the detection element which generates the detection output which responds to the vibration that body of revolution, being the contact inspection method of inspecting the contact of the other object to body of revolution and something regarding the device, especially, in the disk unit, the disk which turns (1) and the slider (2) it offers ideal method and the device to appraisal of mechanical quality. As the detection element which generates the detection output which responds to the vibration (12) it loads in body of revolution (1), rotary trance (33h) through, it transmits that detection output to the fixed part, in order body of revolution (1) to turn that on the basis of the detection output which is transmitted, it constitutes, the aforementioned rotary trance (33h) as for impedance, the aforementioned detection element acquires specified output features that the impedance which is sufficient is guaranteed in the portion of effective sensitivity zone of the aforementioned detection element.
