An articulated robot comprises a movable first transferring portion and a second transferring portion movably supported in relation to the movable first transferring portion by a joint portion. A workpiece is positioned at a position, where a workpiece positional deviation detector is located, by a hand portion formed at an end of the second transferring portion. The workpiece positional deviation, detector detects the amount of deviation in the position of the workpiece. A positioning portion of the workpiece and a sensor portion for detecting deviations of the workpiece are formed either at the first transferring portion to the second transferring portion which form the articulated robot. A detecting operation by the sensor portion and transferring of the first and second transferring portions are enabled when the workpiece is positioned at the positioning portion of the articulated robot.

An optical fiber connector polishing apparatus is disclosed which comprises a polishing element rotated at high speed, a chuck for supporting an optical fiber connector in such a manner that the optical fiber connector is rotatable in a reciprocation mode, a swing arm which holds the chuck to swing the chuck, in a horizontal plane, between a first fixed position and a second fixed position, a positioning unit for positioning the swing arm selectively at the first or second fixed position on the swing locus thereof, a swinging unit for swinging the swing arm in a horizontal plane continuously while the end portion of the optical fiber connector being polished with the polishing element, and a reference member for positioning the end portion of the optical fiber connector at a reference position. The polishing element and the reference member are arranged at the first and second fixed positions of the swing arm, respectively. After, at the second fixed position, the end portion of the optical fiber connector is positioned with the reference member, the swing arm are moved to the first fixed position to polish the end portion of the optical fiber with the polishing element.
