Abstract: A plurality of storage trays are arranged for a stacked relationship relative to one another defined by side walls mounting projections on top surfaces of the side walls received within slots directed through bottom surfaces of an adjacent side wall of an overlying tray. The tray structure defines a cavity between a forward edge of a floor and a rear first wall. A rear second wall is spaced relative to the first wall to mount spaced flanges therewithin, wherein the flanges are further received within openings within an overlying tray. A ratchet plunger is positioned medially of the first rear wall to provide selective projection of a compact disc positioned on the floor in communication with the plunger. A modification of the invention includes an underlying support base formed with fiber optic cables directed through the support base and cooperative with fiber optic cable segments positioned within each of the overlying trays to provide visual indication of proper registration of each tray relative to one another, whereupon misalignment provides a discontinuity in an associated fiber optic cable line indicating such misalignment.

Abstract translation: 布置多个存放托盘，用于相对于彼此限定的堆叠关系，该侧壁由接纳在覆盖托盘的相邻侧壁的底表面的狭槽内的侧壁的顶部表面上的安装突起所限定。 托盘结构在地板的前边缘和后第一壁之间限定一个空腔。 后第二壁相对于第一壁间隔开以在其间安装间隔开的凸缘，其中凸缘进一步容纳在覆盖托盘内的开口内。 棘轮柱塞位于第一后壁的中间位置，以提供与柱塞连通的位于地板上的光盘的选择性投影。 本发明的修改包括下面的支撑基座，其形成有通过支撑基座的光纤电缆，并与位于每个上覆托盘内的光纤电缆段配合，以提供每个托盘相对于彼此的适当配准的视觉指示， 未对准在指示这种未对准的相关联的光纤电缆线中提供不连续性。
