1. An optical connector end face machining apparatus comprising:

  • an operation circuit box having a drive motor and a battery and serving as a grasping section;

    a planetary gear mechanism box including a drive mechanism that rotatably retains a polishing table on a polishing table retainer and permits rotation from the drive motor to be delivered to the polishing table retainer through a planetary gear mechanism; and

    a chuck mounting section fixedly secured to the planetary gear mechanism box, wherein the chuck mounting section includes a chuck that allows a ferrule to be guided with respect to the polishing table for a sliding capability in a vertical direction, and a pressure-applying mechanism that causes the ferrule to be vertically held in pressured contact with the polishing table, wherein the drive mechanism rotates and revolves the polishing table and the polishing table retainer on a surface, opposing to an end face, to be processed, of the ferrule, and wherein the drive mechanism further includes;

    a central shaft standing upright in a frame;

    a sun gear fixedly secured to the central shaft;

    a rotary bearing gear rotatably attached to the central shaft;

    a rotary bearing unitarily formed with the rotary bearing gear;

    a stationary shaft disposed on the rotary bearing;

    a first planetary gear rotatably attached to the stationary shaft and meshing with the sun gear;

    a second planetary gear unitarily formed with the polishing table retainer and meshing with the first planetary gear; and

    a second planetary gear shaft on which the second planetary gear is rotatably supported and supported on the rotary bearing via an arm;

    wherein the presence of a difference in gear teeth between the sun gear and the second planetary gear allows the second planetary gear, the polishing table retainer and the polishing table to rotate and revolve about a center of the central shaft.
