Abstract
A pointer illuminating structure in a measuring instrument. A pointer of the measuring instrument is of a generally elongated structure and transparent. At an intermediate portion thereof, a light inducing section is provided to extend substantially perpendicularly to the generally elongated structure to form a T shape. The pointer has a flat upper surface and lower surfaces extending from about both side of the light inducing section. A reflective material is applied to the lower surfaces. Beneath the upper surface and above levels of the lower surface, cavities laterally extend to open sideways. Said cavities are defined by reflective surfaces. In alternative form, said elongated pointer is formed with a truncated conical portion at the light inducing section. Said truncated conical portion has a truncated conical reflective surface. The reflective material is applied to the side surfaces instead of the lower surface thereof.
