Patent ID: 6848315

Claim:
A vibrating contact detection probe, comprising: a shaft-shaped stylus having a contact portion to be in contact with a workpiece; a vibrator for causing resilient vibration to the stylus when electrical alternating current energy is applied thereto; a detector for detecting the action of the vibration changing in accordance with contact of the contact portion with the workpiece; a vibration energy transmitter for applying the electrical alternating current energy to the vibrator; a detection signal transmitter connected to the detector; and a stylus support and a stylus structure being mutually fitted, the vibration energy transmitter having a first primary magnetic circuit having a first primary coil connected to a vibration energy source and a first secondary magnetic circuit having a first secondary coil connected to the vibrator, the detection signal transmitter including a second primary magnetic circuit having a second primary coil connected to the detector and a second secondary magnetic circuit having a second secondary coil for fetching the detection signal, the stylus, the vibrator, the detector, the first secondary magnetic circuit and the second primary magnetic circuit being integrated on the stylus structure, the first primary magnetic circuit and the second secondary magnetic circuit being integrated on the stylus support, wherein, when the stylus structure and the stylus support are fitted, electromagnetic connection is established between the first primary magnetic circuit and the first secondary magnetic circuit and between the second primary magnetic circuit and the second secondary magnetic circuit and mechanical position of the stylus relative to the stylus support can be reproduced.
