ABSTRACT:
A slide projector system adapted to the projection of a continuous train of slides. The train of slides moves in the form of a slide magazine across the body of the projector parallel to the plane of projection transported by a mechanism that assures movement from left to right in the forward direction and from right to left in the reverse direction. The train of slides moves from an open rectangular tray temporarily attached to the body of the projector on one side into another tray temporarily attached to the opposite side. The train of slides comprises an interconnected series of pockets that are naturally folded in an accordion position from which they unfold in traversing the body of the projector and fold again naturally upon leaving the projector body. The present invention includes the slide projector, the left and right slide trays, the slide train transport mechanism and the accordion slide magazine.
