Abstract
A light guide support mechanism to minimize light transmission loss to the extent possible that houses a light guide in hollow cones such that each of the two end surfaces of the light guide protrudes from the windows of cover members fixed to either external end of the pair of hollow cones that are linked along their axis and that suspend the light guide in the empty spaces in the cones in a suspended state by means of relative rotation of the hollow cones such that the ridges of the light guide are in contact with the edges of the windows in the covers in a point-to-surface or edge-to-surface fashion.
