Patent ID: 7924478

Claim:
A scanner module, comprising: a light source configured to generate light; and a light guide member configured to receive the light from the light source, and to direct the received light toward an object to be scanned, the light guide member having a length and a width, the light source being disposed on at least one longitudinal end of the light guide member, wherein the light guide member includes an exit surface defining a top surface of, and extending along the length of, the light guide member to face the object to be scanned, a reflective surface disposed at a bottom of the light guide member, the reflective surface being configured to reflect the light received, and a pair of light guide surfaces each extending between the reflective surface and the exit surface, the pair of light guide surfaces being configured to direct the light reflected by the reflective surface toward the exit surface, and wherein each of the pair of light guide surfaces comprises a first guide surface and a second guide surface, the first guide surface extending between the reflective surface and the second guide surface, the second guide surface extending between the first guide surface and the exit surface, wherein the reflective surface and the first guide surface defines a first obtuse angle therebetween, wherein the first guide surface and the second guide surface defining a second obtuse angle therebetween, and a first imaginary line parallel to the reflective surface and a second imaginary line parallel to the second guide surface define a third obtuse angle therebetween.
