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.

A slide projector system including a slide projector for projecting slides, comprising:

an accordion slide magazine having a plurality of interconnected pockets with hinge connection means between the pockets so the magazine is foldable at the hinge connection means into an accordion configuration, each of the pockets adapted to hold a slide and permit projection of the slide while remaining in the pocket;
a projection slot extending from an opening on one side of the slide projector to an opening on the other side of the projector for the magazine to pass therethrough, the slot having a projection position therein to project a slide held in one of the pockets;
means to transport the magazine through the projection slot, and
two slide trays positioned one on each side of the slide projector having surfaces substantially level with the openings for the projection slot, the trays having a width equivalent to at least about two pockets to permit the magazine to unfold when being transported through the projection slot.
