1. A transaction terminal comprising:
- a housing;
a display;
a reader, said reader configured to read data from a removable data carrier;
an optical reader unit, said optical reader unit having an imaging axis and a field of view that varies with distance along the imaging axis;
an illumination unit disposed to illuminate at least a portion of the field of view of said optical reader unit; and
a luminiferous shroud extending outwardly from said optical reader unit, said luminiferous shroud disposed perimeterly around the field of view of said optical reader unit, said luminiferous shroud allowing a portion of the incident light emitted from said illumination unit to be transmitted through said luminiferous shroud and dispersed in peripheral directions, said luminiferous shroud having a first end and a second end.

12. An optical reader comprising:
-
a luminiferous shroud including a first end and a second end; a photoelectric conversion unit adapted to read an image, said photoelectric conversion unit disposed proximate to said first end of said luminiferous shroud, said photoelectric conversion unit having a field of view; and a light source disposed proximate to said first end, said light source providing light of a predetermined intensity and energy density; wherein said luminiferous shroud is disposed perimeterly around the field of view of said photoelectric conversion unit; wherein said luminiferous shroud includes a partially reflective inner surface; wherein said partially reflective inner surface reflects a portion of the light incident thereon; and wherein said partially reflective inner surface allows a portion of the light incident thereto to be transmitted through said luminiferous shroud and dispersed in peripheral directions. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
