ABSTRACT:
A detecting device for detecting fluctuation of an arm, to which a stylus is attached, comprises a linear guide installed to an arm supporting member and for guiding vertical or horizontal linear movement, a scale supporting member so installed to the linear guide as to be linearly movable, a jointing mechanism for converting circular arc movement caused by fluctuation of the arm to linear movement of the scale supporting member guided with the linear guide, the jointing mechanism having a jointing pin inserted between a projection integrally formed with the arm at a position of a given distance from an axis supporting part of the arm and the scale supporting member, and a displacement detecting device composed of a scale installed to the scale supporting member for detecting displacement by the linear movement.
