ABSTRACT:
A module for an optical fiber receptacle used in an optical scanning device forming a latent image on a photosensitive body by scanning a laser beam emitted from the optical fiber, the efficiency of light use is improved. The module includes a module holder having a semiconductor laser for generating a laser beam, a lens for condensing the laser beam emitted from the semiconductor laser and a lens holder for holding the lens; a flat glass plate arranged on the optical path of the laser beam and fixed in the module holder; an optical fiber fixed onto a surface of the flat glass plate opposite to the surface facing the semiconductor laser through a photo-curing resin. The flat glass plate, the photo-curing resin and the optical fiber are made of materials having approximately equal refractive indexes.
