Abstract
The mounting device for a resin lens, used for refracting a light beam in the formation of an image, has a housing in which laser diode and bimetals are supported. An acrylic-resin lens, for use as the resin lens, is supported by the bimetals. As the ambient temperature changes, the focal point of the lens is displaced, and at the same time, moving parts of the bimetals are displaced. As its focal point is displaced in this manner, the lens shifts its position. Thus, the position of the focal point of the acrylic-resin lens is corrected by means of the bimetals.
