ABSTRACT:
A miniature slide storage tray having a plurality of annularly arranged, radially extending compartments for receiving and storing a plurality of slides in a compactly arranged manner so that the storage tray and slides require a minimum of storage space. An annular slide transfer tray having a plurality of radially extending compartments corresponding to the compartments in the storage tray is temporarily engageable with the storage tray and the mated storage and transfer trays are temporarilyengageable with an associated, annular, slide projection tray. Alignment and indexing structure maintains alignment between the respective compartments in the storage, tranfer and projection trays when these parts are in mated relationship. Transfer of slides between the compartments in the storage and transfer trays is effected by radially shifting the slides between these compartments and transfer of slides between the compartments of the transfer and projection trays is effected by gravity by inverting the mated trays. A novel method is employed to transfer slides from the compartments of the slide storage tray into the compartments of the slide transfer tray and thence into the compartments of the associated slide projection tray, and vice versa.
