Abstract: Apparatus (36, 37 and 38) adapted for association with a projector (11) and a compartmented magazine (12) for containing photographic slides for said projector whereby a stack of slides (42) contained in said apparatus are loaded into said magazine utilizing the slide removing (32, 33) and magazine advancement (29) mechanisms contained within the projector.

Abstract: The disclosure relates to a rectilinear transport means particularly adapted for transporting a rectangular array of individual photographic film elements one at a time into register with the axis of a projector lens or the like or for the purpose of moving or controlling the movement of other objects in a generally rectilinear manner with respect to a generally rectangular array of elements or portions; the disclosure including a simple mechanical rotary actuator and indexing means wherein the rotary actuator continuously rotates in one direction and drives the indexing means back and forth in a generally serpentine path by engaging successively indexing portions spaced in rows generally parallel to each other and whereby the rotary phase direction of the rotary indexing means when it reaches opposite ends of the rows in the rectilinear path causes a reversal of direction in the movement of the indexing means so as to progressively move in one direction and then the other and wherein the disclosure also rela

Abstract: The disclosure relates to a micro fiche transport means adapted to transport a micro fiche in rectilinear directions at right angles to each other for projection relative to a plurality of micro photos carried thereby; the transport means having a plurality of parallel rows of indexing portions disposed at right angles to each other and intersecting each other and also a rectilinear track means and a plurality of generally herring bone shaped cam means operable by a rotary cam member which is limited by a single or partial revolution clutch.

Abstract: A drive mechanism for a spiral array of individual film photographs comprising a rotary driving plate having a spiral array of switch operating portions adapted to energize a driving motor for driving the driving plate; rotary axis means coupled to said driving plate; a photographic mount coupled to said rotary axis means and carrying a spiral array of individual photographs. A rectilinear bearing means on said frame adapted to guide said rotary axis means and said rotary driving plate together with said photographic mount in a rectilinear path laterally of the rotary axis of said rotary axis means, and mounting means carrying a track follower adapted to operate said switch and engagable with said switch operating portions. The track follower engaging a spiral track means on the rotary driving plate and serving to index said plate relative to said swith operating portions and also to activate said rotary driving plates in a direction along said rectilinear bearing means.
