Graphical code reading apparatus for reading codes on reflective surfaces

A graphical code reading apparatus for reading a graphical code on a reflective surface, comprising:

• a graphical code reader having an illumination source and a detector, the illumination source emitting electromagnetic radiation;
• a transmissive diffuser insert that includes a window, wherein the detector receives a reflected image of the graphical code without the reflected image being impeded by the transmissive diffuser insert, and wherein the transmissive diffuser insert is located within an interior portion of a light scattering chamber, wherein the transmissive diffuser insert is located in an area of the interior portion of the light scattering chamber that is not tapered;
• and
• an irregularly uneven reflective surface that scatters the electromagnetic radiation emitted from the illumination source, such that the electromagnetic radiation impinges the reflective surface from multiple angles of incidence.

A light scattering chamber for enabling a graphical code reader to read a graphical code on a reflective surface, comprising:

• an interior portion and an exterior portion;
• a first opening configured to receive a portion of the graphical code reader;
• a second opening for placement adjacent a graphical code, the second opening opposite from and smaller than the first opening;
• a light scattering surface on the interior portion that scatters electromagnetic radiation emitted from the graphical code reader in random directions before the electromagnetic radiation impinges upon the graphical code on the reflective surface;
• and
• a transmissive diffuser insert that includes a window, wherein the detector receives a reflected image of the graphical code without the reflected image being impeded by the transmissive diffuser insert, and wherein the transmissive diffuser insert is located within the interior portion of the light scattering chamber, wherein the transmissive diffuser insert is located in an area of the interior portion of the light scattering chamber that is not tapered.
