Abstract
Abstract An optical connector tip polisher which comprises a stationary block for supporting a wheel spindle stock, a manual slider for supporting an optical connector and a cam mechanism. The stationary block has a base for mounting the wheel spindle. The base has a guide space and a guide opening. The manual slider has a horizontal stock, a post and is a holder. The horizontal stock is fitted in the guide space of the base and restricted against movement in the vertical direction while being movable along a horizontal plane. The post is embedded in the horizontal stock and is movable in unison therewith. The post extends upright through the guide opening of the base. An idling wheel is provided between the inner periphery of the guide opening and the outer periphery of the post to guide the post along the inner periphery. The holder is secured to the post at an intermediate position thereof and holds an optical connector to perpendicularly press the tip of the optical connector against the wheel spindle stock.
