摘要： An optical type displacement detecting device including a main scale and an index scale, wherein a pitch of a first optical grating formed on the main scale is set at P and a pitch of a second optical grating formed on the index scale is set at P/n, thereby producing divided detection signal having pitch P/n. Furthermore, the pitch of the second optical grating is set at (u+v) P/u or (u+v) P/(2u) (u is a gap between a diffusive light source and the first optical grating and v is a gap between the first and second optical gratings), so that a collimator lens can be dispensed with. Further, higher harmonic components of the first optical grating are utilized, whereby the pitch of the second optical grating is set at substantially (u+v) Q/u or (u+v) Q/(2u) (Q=P/m, and m is a whole number of 2 or more), thereby preventing the pitch of the second optical grating from being divided into small ones.

摘要： A coordinate measuring instrument wherein a measuring element is related to a work to be measured, and a configuration or the like of the work is measured from a displacement of this measuring element. In this measuring instrument, one of supports is supported by one of guide rails in a manner to be positionally adjustable in direction of X- and Z-axes and the other of the supports is supported in a manner to be displaceable only in a direction of one of the guide rails. A slider guide rail racked across the supports can be adjusted in its posture in the direction of X- and Z-axes by a posture adjusting mechanism provided on connecting portions between the slider rail and the supports. The slider guide rail thus adjusted in posture in non-displaceable in the moving direction of a slider in a state where adjustment members provided on the slider guide rail are closely abutted against abutting surfaces of the supports.
