1. An adjustable scanner mounting assembly, comprising: a pair of first mounting rails forming a part of opposite walls of a scanner/scale device housing or adapted for attachment to opposite walls of a scanner/scale device housing;a pair of second mounting rails adapted to cooperatively support a scanner and extending transversely between the first mounting rails and slidably connected thereto, a scanner retention wall extending upwardly from and along the length of each second mounting rail; andat least one scanner locating mechanism movably affixed to each of the second mounting rails so as to be slidable along the length thereof;wherein, positional adjustment of a scanner along a first axis is accomplishable by sliding the second mounting rails along the length of the first mounting rails; andwherein, positional adjustment of a scanner along a second axis is accomplishable by sliding the scanner locating mechanisms along the length of the second mounting rails. 2. The adjustable scanner mounting assembly of claim 1, further comprising a plurality of rail retention devices configured for releasably securing ends of the second mounting rails through associated slots in the corresponding first mounting rails. 3. The adjustable scanner mounting assembly of claim 2, wherein: each rail retention device includes a spring-loaded pin;each one of the pair of second mounting rails includes a hole near each end thereof; andwhen the rail retention devices are installed to the second mounting rails, the pin of each rail retention device is adapted to extend through one of the holes in the respective second mounting rail and through the slot in the respective first mounting rail to releasably clamp the second mounting rails against the first mounting rails. 4. The adjustable scanner mounting assembly of claim 1, wherein each scanner locating mechanism includes a scanner stop element having a base leg that engages a slot in the second mounting rail to which it is installed, and a locating tab that extends upward from the base leg. 5. The adjustable scanner mounting assembly of claim 1, further comprising a scanner locating mechanism retention device associated with each scanner locating mechanism and adapted to releasably secure the scanner locating mechanism base leg to an associated second mounting rail through at least one slot located therein. 6. The adjustable scanner mounting assembly of claim 5, wherein the scanner locating mechanism retention device includes a spring-loaded pin that is adapted to extend through the at least one slot in the second mounting rail to which the associated scanner locating mechanism is installed, and to releasably clamp the base leg of the scanner stop element against a top or bottom surface of the second mounting rail. 7. The adjustable scanner mounting assembly of claim 1, further comprising position indicating markings located along the length of each of the first mounting rails and the second mounting rails. 8. The adjustable scanner mounting assembly of claim 1, wherein the second mounting rails are adapted to permit adjustment of the spacing therebetween and the scanner locating mechanisms are adapted to permit adjustment of the spacing therebetween, such that the mounting assembly can accommodate scanners of dissimilar dimensions. 9. An adjustable scanner mounting assembly, comprising: a first mounting rail set having a pair of first mounting rails forming a part of opposite walls of a scanner/scale device housing or adapted for attachment to opposite walls of a scanner/scale device housing;at least one slot extending along the length of each first mounting rail;a second mounting rail set having a pair of second mounting rails adapted for releasable attachment between the first mounting rails of the first mounting rail set;at least one slot extending along the length of each second mounting rail;a scanner retention wall extending upwardly from and along the length of each second mounting rail;rail retention devices, each including a spring-loaded pin, for releasably clamping the second mounting rails against the first mounting rails through the at least one slot in each of the corresponding first mounting rails;a plurality of scanner locating mechanisms releasably affixed to each of the second mounting rails, each scanner locating mechanism including a scanner stop element having a base leg that engages the at least one slot of the second mounting rail, and a locating tab that extends upward from the base leg; anda scanner locating mechanism retention device associated with each scanner locating mechanism, the scanner locating mechanism retention device including a spring-loaded pin adapted to releasably clamp the base leg of the scanner stop element against a top or bottom surface of the second mounting rail through the at least one slot located therein;wherein, a scanner is supportable on the mounting rails of the second rail set, between the scanner retention walls thereof;wherein, positional adjustment of a scanner along a first axis is accomplishable by sliding the second mounting rails along the length of the first mounting rails; andwherein, positional adjustment of a scanner along a second axis is accomplishable by sliding the scanner locating mechanisms along the length of the second mounting rails. 10. The adjustable scanner mounting assembly of claim 9, further comprising at least one guide tab extending from the base leg of the scanner stop element and adapted to fit within the at least one slot located in the second mounting rail. 11. The adjustable scanner mounting assembly of claim 9, further comprising position indicating markings located along the length of each of the first mounting rails and the second mounting rails. 12. The adjustable scanner mounting assembly of claim 9, wherein the second mounting rails are adapted to permit adjustment of the spacing therebetween and the scanner locating mechanisms are adapted to permit adjustment of the spacing therebetween, such that the mounting assembly can accommodate scanners of dissimilar dimensions.
