ABSTRACT:
This disclosure depicts a ray beam converter having a rotary mirror driven by a motor, for reflecting ray beams to convert the same into rotary scanning ray beams in an optical measuring instrument wherein the ray beams from a beam generator are converted into the rotary scanning ray beams to be scanned in one direction and dimensions of a workpiece to be measured are measured by utilization of the rotary scanning ray beams. A rotor of the motor is rotatably supported by bearings at a plurality of positions in a direction of the rotary axis of the motor, and the rotary mirror is integrally formed on the rotor at a portion of the rotor supported by at least two bearings to each other out of the bearings. The rotary mirror is integrally formed on the rotor at a portion of the rotor supported by at least two bearings, and the rotor is rotatably coupled to a spindle affixed to a stator of the motor through the bearing. The spindle is provided with a tubular portion to be coupled with a portion of the spindle protruding from the main body. The rotary mirror is integrally formed on the tubular portion.
