ABSTRACT:
A lens-holding apparatus used for holding a hexagonal lens and for fixing the light receiving end of an optical conductor at the focal point of the lens includes a frame body having a hexagonal portion on at least a part thereof, a hexagonal lens tightly inserted into the hexagonal portion, and an optical conductor cable fixing mechanism for fixing the light-receiving end of the optical conductor at the focal point of the lens on another portion of the frame body. The hexagonal portion comprises six side surfaces, every other one of which has two slits formed symmetrically in relation to the center line of each side surface in the longitudinal direction for mounting the lens thereon and a tongue piece formed between both slits. The lens is tightly inserted into the hexagonal portion and held therein by means of a tongue piece for pressing the lens.
