ABSTRACT:
Apparatus for processing an end face of an optical fiber connector includes a rotatable index shaft mounted on a frame. A plurality of rotatable chucks are mounted on the index shaft so as to hold optical fiber connectors, respectively. In accordance with the rotation of the index shaft, the chucks can be moved sequentially from one index position to another so as to grind and finish the optical fiber connector. A rotatable drive gear is disposed coaxially with the index shaft. A driven gear is fixedly mounted on each chuck. A pair of first and second intermediate gears are connected to the drive and driven gears, respectively. A clutch is interposed between the pair of intermediate gears and normally connecting them together to transmit the rotation of the drive gear to the driven gear to rotate each chuck. A clutch disengagement device is provided for disengaging the clutch to disconnect the two intermediate gears when each chuck is indexed to a position where the optical fiber connector is attached to and detached from the chuck.
