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 polishing apparatus for optical fiber end surface is constituted by including a base 14, a rotary disk 15 supporting a polishing member for forming a polishing plane and rotatably set to the base, ferrule holding means 21, 22, and 21A removably supporting one optical-fiber ferrule 23 or more, vertically guiding means 21, 22, and 21A vertically movably supporting the ferrule holding means in parallel with the polishing plane and moving between a preparation position and a polishing end position, urging means 33 and 34 for urging the vertically guiding means supporting the ferrule holding means 18 and 20 in the direction vertical to the polishing plane, vertically driving means 30 for vertically driving the vertically guiding means supporting the ferrule holding means 21, 22, and 21A, and a control circuit for driving the vertically driving means.

La présente invention porte sur un appareil de polissage de la surface de l'extrémité des fibres optiques, permettant de régler librement la pression de contact entre un plan de polissage et la face de l'extrémité distale d'une ferrule, et pouvant empêcher de produire un composant défectueux au polissage. L'appareil de polissage de la surface de l'extrémité des fibres optiques comprend une base 14, un disque rotatif 15 supportant un élément de polissage pour former un plan de polissage et réglé sur la base de façon à pouvoir tourner, les dispositifs de retenue 21, 22 et 21A de ferrule supportant de façon non permanente une ferrule 23 ou plus de fibres optiques, guidant verticalement les dispositifs 21, 22 et 21A, supportant verticalement de façon mobile le dispositif de retenue de la ferrule en parallèle avec le plan de polissage et se déplaçant entre une position de préparation et une position de polissage de l'extrémité, poussant les dispositifs 33 et 34 de façon à pousser le dispositif de guidage vertical, et supportant les dispositifs de retenue 18 et 20 de la ferrule dans la direction verticale au plan de polissage, entraînant verticalement le dispositif 30 de façon à entraîner verticalement le dispositif de guidage vertical, et supportant les dispositifs de retenue 21, 22 et 21A de la ferrule, et un circuit de commande servant à entraîner le dispositif d'entraînement vertical.
