Abstract
The present invention provides a polishing apparatus for optical fiber end surface making it possible to freely adjust the contact pressure between a polishing plane and the distal end face of a ferrule and capable of preventing a defective product from being produced under polishing. A control circuit drives a vertically driving mechanism to allow a ferrule holding plate to move from a preparation state to a ferrule polishing starting state and by compressing a spring it then allows the ferrule holding plate to lower further beyond the starting state to complete the polishing.
