Abstract: An apparatus is set forth wherein a housing includes a forward wall spaced rearwardly of and parallel to a rear wall, wherein the forward wall is of a lesser height than that of the rear wall, with a floor extending rearwardly of the forward wall spaced from the rear wall, with a first inclined wall extending upwardly and rearwardly of the floor spaced below and parallel to a second inclined wall extending above and rearwardly of the first inclined wall, wherein the first and second inclined walls are arrranged at an obtuse angle relative to the floor. The housing includes a series of spaced cylinders defining cassette cradles therebetween to accept pivot cylinders mounted to a floor of an associated cassette holder, wherein the cassette holders are removably and pivotally mounted relative to the housing and are pivotally arranged thereto by the pivot cylinders received within the cradles.
