Abstract:
An adjustable reader arrangement for reading encoded sound-related indicia, comprising:(a) an object having encoded first sound-related indicia and an image formed as a print on a first side of said object and encoded second sound-related indicia formed on a second side of said object, the first indicia defining a predetermined first quantity of information associated with the image and being invisible to humans and the second indicia defining a predetermined second quantity of information associated with the image, the second quantity of information including the first quantity of information; (b) a base disposed relative to said object; (c) a detector removably connected to said base for detecting the first indicia and the second indicia, said detector having a first portion adapted to be removably connected to said base and a second portion adjustable into alignment with the first indicia or the second indicia formed on said object, wherein the second portion of said detector is adjustably pivotable through an angle of approximately 120 degrees with respect to the first portion of said detector and wherein the second portion of said detector is adjustably rotatable through an angle of approximately 360 degrees about a longitudinal axis extending through the first portion; and (d) a sound emitter coupled to said detector for emitting a sound indicative of the first indicia and the second indicia detected by said detector.
