Abstract
A receptacle has an end surface supported along a plane extending at right angles to the axis of the receptacle and a contact surface at the other end. The contact surface also extends at right angles to the axis of the receptacle. A receptacle holder has a recess within which the receptacle is received. An adjusting mechanism is devised to adjust radial position of the receptacle. A lens holder is attached to the other end of the receptacle holder. A slide member has a sliding surface in surface contact with the contact surface of the receptacle. The slide plate is urged toward the one end of the receptacle so as to bring the sliding surface into contact with the contact surface of the receptacle. An optical fiber is inserted into the receptacle through a ferrule. If the optical fiber is twisted, the slide plate permits ready rotation of the receptacle in a torsional direction so as to prevent the optical fiber from being subjected to torsional stress. Also, opposite ends of the receptacle are gripped in surface contact and supported in a plane extending at right angles to the axis of the receptacle holder. This arrangement prevents inclination of the receptacle and thus, optical …
