Abstract

PURPOSE: To obtain a unit which provides display of respective axis component of X and Y coordinates in terms of the center position of a stationary body and a shift from the rotation axis of a boky of revolution by providing a shift detector, signal generator which generates a signal corresponding to the rotation, multiplier for its output, and unit which draws its output on the XY coordinates.
CONSTITUTION: Spindle 1 is driven by motor M through worm 2 and worm wheel 3. Spindle 1 is provided with eccentric cam 4, and displacement detector 5 which detects the center position from the circumferential surface of stationary body A. Eccentric cam 4 is also provided with detecting elements 6a and 7a of two displacement detectors 6 and 7 at positions with an angle difference of 90°. Both displacement detectors 6 and 7 generate cosine-wave and sine-wave signals according to the rotation of eccentric cam 4. To eccentric cam 4, displace detecting element 5a is fitted in contact with stationary body A. Those signals are multiplied 11 and inputted as X and Y inputs to oscillograph 12 to draw Lissajous' figures, so that a shift will be detected from the figures.
